What Do You Think About LIFX LED Strips and Can They Light a Small Bathroom ?

They look pretty cool. According to the company's website a 2-meter strip gives 1400 lumens. A 75-watt bulb (which is bigger than what I've got in my own bathroom) only gives 1100 lumens. So, it should work fine in your bathroom.

1. I want to install led strips under my dash how do i wire them up 2 turn on only wen i turn my headlights on?

tap into the incoming power on the dimmer switch , or you can tap after and the dimmer will allow you to turn them up and down

2. How many of these LED strips should I install. 2 or 3? Ecoxotic Panorama Pro 12K?


3. Can I hook up multiple LED strips to 1 Toggle Switch?

particular i would use a connector that suits the toggle & connect the wires to that. and twine length does be counted to small it gets warm, you do not desire a twine thats to special it want harm in spite of the undeniable fact that it rather is huge and cumbersome,examine on line for the stunning sizes of twine for various purposes. good success

4. how to tie in led strips to subs so that they strope when bass hits?

just connect the LED wires directly to the wires 2 wires that are connected to the back of your speaker, its not going to blow them because the LEDs will only use what the speakers use and 1500W will blow the speaker before the LEDs...youll be fine

5. i have 10 led strips what would be the best way to power them?

I got led strips on my car to, just wire them to the battery. Have someone that knows what there doing install it. Its dangerous if you dont you could cause a fire or something if it shorts. I googled everything and i cant seem to find anything. Im sure if you keep searching or ask someone thats good with electric they will know. You need to wire it to some type of battery. Most LEDs dont require alot of power. Sorry i wish i could give you more info man

6. where can i buy the purple led strips?

hi, we are making LED strips, then I will send list to you.

7. Controlling 10x 5m led strips with 10 individual analog floor switches

Unless you want to do fancy things with the LED strips you really do not need an Arduino to accomplish this task. You can just switch each strip with a powerful enough MOSFET and control the gate with the sensor:simulate this circuit - Schematic created using CircuitLabIf you really want the Arduino (for example to add effects like delays, fading, blinking patterns, etc) it would basically go into the circuit at point A in the circuit. The sensor into an input and the MOSFET into an output. Since these are just presence sensors (not pressure sensors, they do not sense pressure, only presence) you do not need an analog input to read them - a digital one will suffice and also make your programming simpler.You can use shift registers or IO expanders to increase the number of input and output pins you have, or you can use a larger Arduino with more pins

8. Are there any rgb LED strips that auto fade?

ebay amazon?

9. Is it possible to use a raspberry pi to control these LED strips?

For DMX512 you need a UART capable of 250000 baud and 8 data bits with two stop bits (or 8 data bits a space for parity and one stop bit) I tried a cheap* RS485 dongle and while it claimed to manage the necessary framing minicom could not make it do 250000 baud.I am not sure what the exact capabilities if the Raspberry Pi main UART are.(*)it cost less than $1it looks like FTDI uarts can do 250000 Baud so one of them and an RS485 interface chip should probably get you there. You can of course buy DMX adaptors that connect to USB or to GPIO but shopping questions are off topic here

10. i want to install led strips under my dash how do i wire them up 2 turn on only wen i turn my headlights on?

LiTTT Snaps LED Strips Together Without Solder
LiTTT Snaps LED Strips Together Without Solder
Programmable RGB and RGBW LEDs, especially in strip form, have revolutionized the kind of lighting effects that creators can easily make. Working with strips, however, normally means breaking out the soldering iron. If for some reason you need to make changes, you then have to repeat the process over again — hopefully without damaging anything.If you’d prefer for things to be more plug-and-play, the LiTT Snap! system, by Daniel Tooker, features electrical connectors that — you guessed it — simply snap together. They form connections by bending the strip inside of a square piece of RPVC extrusion, or into an equivalent 3D-printed shape. The system is now available on Kickstarter, featuring 90 and 45 degree connectors, extrusion, and the RGBW LEDs themselves, along with the pigtails needed to connect everything to power and your favorite dev board.It’s an interesting concept, but the stretch goals expand things even further, including a 135- and 180-degree connector, as well as mounting hardware, and even a rotating corner connector. As an added bonus, if successful, this campaign will help in the development of the LiTTT HUB. The aim of the hub is to be a connected lighting controller “to rule them all,” further simplifying what you can do with these amazing strips!.·RELATED QUESTIONWere can I get quality outdoor LED lighting for my landscape project?If short maintenance, eco friendly landscape lighting is a precedence for you, outdoor LED lighting is a ideal option for your landscape lighting design.

Chaining Up 5v LED Strips Using 5v Cellphone Chargers [duplicate]
If you go on ebay they sell 1 male to multiple female connectors. Having multiple power supplies is not ideal because if one goes out it puts stress on the LED strip and could short out the strip and other power supplies. With one power supply and wires to divide it evenly if it goes out, the whole thing goes out without the risk of a short in the microchips in the strip. One strip one power supply is best. An adjustable power supply to lets you choose your voltage and amperage and they are cheap. The 50/50 rgb has more versatility then that brand in you picture which looks like a 30/30. The 50/50 come with built in power connectors. You will have more difficulty tracking down the bad power supply in your example if it goes bad without a multi-meter.If you hard wiring this without a control box(small control CPU that con be programmed for sequenced patterns and brightness) a 3 12volt dimmer switch for each color would work. The control box does have a timer and can be thrown off by multiple power supplies. Some of the answer came from the comments1. im trying to make sound reactive LED strips for a car subwoofer?definite, that is conceivable, yet you gotta make constructive your sub is not stressed out down bypass 4 ohm, otherwise your reciever will bypass into look after mode. I also advise you hook up a house sub extremely of a motor vehicle sub. They both are outfitted in yet in a unique way and the residing house sub will sound alot extra proper. sturdy success.2. Why are most RGB LED strips common anode instead of common cathode?I was not able to find any definitive reasons, but I did come across:- EEng (source)It may be that the slight advantage that sinking current offers over sourcing for most devices, leads manufacturers more often to design displays in a common anode configuration3. Why don't people power LED strips in parallel instead of using amplifiers?Watts = Volts x Amps, so the current and wire size required to deliver a certain amount of power with minimal voltage drop is much larger at 12V or 24V than at 110V or 230V, and that thick cable has to be run all the way from the power source. Where will you put the cable? Not in the LED strip channel because there is not room. Not alongside it as that would be unsightly. That leaves in the ceiling or under the floor, which makes for a difficult installation. But let's say you do not mind seeing the extra cable or crawling through the ceiling to get it to the destination - just how much larger does it need to be to eliminate visible loss? The human eye is very sensitive to intensity variations, and the strips have multiple LEDs in series so they are quite sensitive to voltage drop. So to achieve 'insignificant' power loss the current has to be much lower than the ampacity of the cable. Therefore the cable needs to be oversized. A typical LED strip may draw several Amps - your cable might need to be rated for tens or even hundreds of Amps to match the output voltage of a local controller. However the room probably already has multiple mains power points that can be tapped into to supply additional LED drivers. So now you do not need to run a long thick cable to each remote LED strip, and each strip gets full voltage from a local power supply so it has the same brightness. The only problem is how to operate them all from a single location. LED 'amplifiers' or are peaters' solve this problem.4. How To Create Ambient Lighting with LED StripsHow To Create Ambient Lighting With LED Strips Ambient light is defined as the general illumination within a space. The availability of ambient light throughout the home is one of the most critical considerations in interior design. With LED strip lights, there are many more ways to effectively create ambient light to brighten the home for family and guests. Strip lights capitalize on the well-known benefits of LED technology - providing ample, beautiful light with low energy costs and incredible durability. But there is another important factor exclusive to strip lights, and that is their supreme design versatility. Our strips can be cut, curved and connected to fit any space and shine light exactly where you want it. Here are four ways to create attractive ambient light with LED strips: One of the best uses for LED strip lights is in indirect lighting projects. Indirect lighting is a great way to add focus, texture, layering and accent color to rooms throughout the house. Many people choose to run the strips above cabinets in the kitchen, behind mirrors in the bathroom, or in coves through hallways. Modern designers have expressed a preference for indirect lighting because of the way it hides fixtures and because it produces an evenly distributed glow of ambient light throughout the room. Pro Tip: Take extra care to make sure the high energy areas of your house have ample lighting. Where does the family gather? In the kitchen or the living room? Make sure that the lights you install are bright enough to energize a crowd, making everyone feel lively and excited to be together. Our LED strips are some of the very brightest LEDs you will find on the market. Ambient light in a room is not only measured by how attractive it is, but also by its functionality. One advantage of LED strips is that their versatility makes them great for task lighting installations. LED strip lights are perhaps the best solution there is for under cabinet lighting - a common example of home-based task lighting. Further, this is a simple DIY project that wo not require a huge electrician expense. To add kitchen task lighting, just peel back the adhesive on the back of our strips, stick them under the cabinet and connect them to a power source for incredible kitchen task lighting. Pro Tip: When installing task lighting, it's a good idea to put in more light than you think you will need. First, these lights will last many years into the future, and who could not use more light as the years go on? Second, when you are focusing on a task, more light means better concentration and improved accuracy. Dimmers are important for creating the right ambient light atmosphere in the home. With dimmers, you can turn down the lights as night falls, which will relax your mind and bring you closer to sleep. Dimmers can also be used to add light to a room where natural light normally enters, but perhaps clouds are letting in less light than normal and you need a little extra. With a dimmed LED strip lights, you will have full control to add the perfect level of light necessary for any given situation. Pro tip: Before you add a dimmable LED strip lighting system, it is a good idea to consider whether you want a hardwired wall dimmer or a remote inline dimmer. The first option is easier if you have a professional electrician on hand, while the second option can be done as part of a DIY installation. LED strip lights can also improve a room's ambient light by adding accent. Running strips along toe kickers or under counters is a great way to add color or textures to a room. With LED strips, the possibilities are only limited by your imagination. If you are looking to add an extra creative flair, add color-changing RGBs and harness the power of color psychology. For instance, say you want to create an excited mood in a room, add red light and the occupants will feel stimulated and passionate. On the other hand, add blue light and the occupants will feel relaxed and comfortable. Pro tip: Many color changing LED strips on the market are of low quality. Be sure to compare options before making your purchase and make sure that the lights come from a trusted brand. While many lights claim to last 25,000 to 50,000 hours, make sure there is a warranty on the product to guard yourself against disappointment.

LED Lights Flexible LED Strips, LED Strips?
Is the LED strip battery powered, perhaps intended for car use? If so you can. If it is mains powered then that becomes more uncertain, waterproof normally means splash proof not immersion proof1. If you hate led zeppelin?! who hates led zeppilen? O.o zeppilen kicks a**2. led lights for growing!?Forget the LED's for growing. They do not throw the UV's flourescent or HID bulbs do. That is what will make your plants grow3. Mag light LED conversion?Yeah, it's expensive. But the LED conversion actually does a better job in one respect. The mag lights let you focus the light from a wide flood to a spot. The LED conversion will let you continue to do that. The flashlights with multiple LED's can not do this. You can not have all the LED's at the focal point so the light will always be difuse in a flood mode. You can not get a real spot to shine a distance. Even if one of the LED's were in the focal point, the other LED's mounted around in the reflector will destroy the narrow beam4. What tv should I buy? LED, LCD, or combination LCD/LED?All led are a combo of LCD and LEDS some are edge lit and other run across the entire back of the tv. these are LED advantages lighter better color than LCD life span is longer(up to 100,000 hours) LCD is about 60,000 doesent overheat like a LCD( kills the life of the tv) and you can get anything other than a LCD or LED at that size. toshiba is a good brand.5. Samsung led tv specifications?The UE40B6000 is Samsung's entry level LED TV and certainly the .... However, as you will notice later in the review, it does not stay there6. What are the advantages of design-led and development-led web apps?There are not advantages to either.David Kelley (IDEO) introduced the concept of the three lenses of design:Desirability (What do people desire?) - This is led by IXD and UX designers.Feasibility (What is technically and organizationally feasible?) - This is led by developers. Viability (What can be financially viable?) - This is led by business stakeholders. A successful product lies at the intersection of these three concerns.Forcing a hierarchy among three critical components is not necessary when you have intelligent people who are able to understand and appreciate the perspective and role of the other two.7. what led to FARMING IN CHINA?farming has been a part of life since day one, tehy grew the same things they do today, rice, corn, peanuts, fruits and so on8. Light bulb in replace of LED?You can stick it in and try it. But I doubt it will work for you. Incandescent light bulbs work by getting very hot. You either need high voltage or high current, or both, to light a light bulb. LEDs on the other hand, work by driving a specific interaction within the device. An LED usually operates at a low voltage and a low current. Furthermore, LEDs only work at specific voltages and currents, while a light bulb will work at a very broad range of voltages and current. I have no idea what the 308 ohm resistor is in your circuit, but if I had to guess, I would guess that it is a voltage divider to reduce the source voltage to the value required by the LED. If that is the case, removing or replacing the resistor would probably make the light bulb work better. Whether you want to remove or replace would depend on the circuit's configuration. In any case, I would guess that your LED circuit will not be able to light your light bulb no matter what you do.9. Multiple led drivers for a single LEDYou can not in general connect multiple drivers to a single LED, they are likely to damage each other.Why do not you replace it with four white LEDs, each connected to a single driver? That way it should be electrically good and you can adjust the brightness by an extra 6dB10. Help with Led Zeppelin shirt?I prefer the second one, but both are nice11. led light circuit ? ?"when i remove the power i would then like them to power down 1 at a time in sequence" Ca not do this, as you have no power to keep them lit. But you may be able to use a very large capacitor to supply that energy. If they are drawing 10mA each, that is 160mA average. If the power down sequence takes 1 second total, you would need a 10000 to 50000F cap. But the cap would take a lot of energy to charge up, and would be physically large and expensive. .

LCD Industry Touch LCD Screen Slow Response How to Do, What Treatment
With the development of science and technology, LCD touch-screen can be seen everywhere, especially in industrial production. Then, LCD industrial touch LCD screen occasionally has some faults, such as touch insensitivity, so what causes this phenomenon? Xiaobian came to solve our doubts.If the touch screen on the industrial touch surface reacts slowly, it may be that the touch screen system is old, the internal clock frequency is too low, or there are water droplets on the touch screen surface and it cannot be moved. In order to restore the touch screen to rapid response, the system driver must be replaced or upgraded, or the touch screen surface must be wiped with a rag. In general, this is common for multi touch screens, but care should be taken to maintain them. In the detailed operation and use, the following problems must also be paid attention to:1. TP is a glass product. Please handle it with care to avoid damage and rupture.2. The contact surface of TP is a conductive film. If the protective film is torn off, it is forbidden to contact the product surface with sharp objects such as nails, pencils and so on, so as to avoid soiling and scratching the product.3. Do not stick oil, water and other liquids on the surface of the product.4. When there are stains on the touch surface, please gently touch the alcohol with a degreasing cotton ball or dust-free cloth, and gently wipe the product surface. Do not infiltrate the alcohol into the product.5. Avoid the use and preservation of organic solvents or corrosive gases (acid gases, etc.).6. When installing the machine, please use non corrosive glue to fix the product.7. When installing the machine, please wear fingertips or gloves to ensure the cleanliness of the product.8. When TP is found to be ineffective, please check whether there is faulty welding, whether the pin contact is good, whether the machine is installed correctly and whether the operation touch position is accurate. If there is no such problem, please stick the protective film back to the product surface to ensure that the product is returned to the manufacturer for analysis and treatment.9. After unpacking inspection, keep the original package sealed and stored to prevent the product from being affected by high temperature and high humidity, resulting in watermark on the glass surface of the product.The above content is the problem of slow response of LCD industrial touch LCD screen. Doing these protective measures well and protecting the touch screen as much as possible can delay its service life and avoid slow response.fqj

Baby Wont Sleep Unless Home...HELP?congratulations for your new child. I actually have a two week historical son, it is robust is not it? Something I did for my son was once lifted up the matress on his bassinett and placed a blanket beneath it to hold him extra upright. I did not do that given that he was not sound asleep in it, I did it given that he's having a predicament with a few publish nasal drip and I was once hoping to avert a few of it from happening his throat, however it sort of feels to be running quality so far as him sound asleep greater too. He too likes to be held while he's sound asleep however propping up his matress and giving him an incline turns out to fulfill him. Something else you would wish to provide a check out if you have not already. Before mattress time provide him a first-class hot tub utilizing the Johnson and Johnson bedtime tub merchandise.

How do I make my indoor cats outdoor cats at a new home? HELP!?gradually introduce them to the outdoors. hold them in your arms while outside so they can see how wonderful it is outside. then, after about 10 minutes of holding, you go back inside and feed them a special treat they like, so they know that the outside is a fun place to be, but they always come home to get all of the love and attention you provide for them. after a few times of this, use a cat harness (available at petsmart) and let your cat feel the ground under its paws. once again, after like 10 minutes, bring her back inside and show her why she does not want to run away (by showing her that you provide love and attention). then, after you are confident with that, let her off the harness, BUT STAY VERY CLOSE! this will show her that she has freedom, but also that you have a wonderful home for her. cats are very loyal, so if you do this gradually, she will always come back. cats are loyal. i heard a story from Hurricane KAtrina that said this man had to leave his 3 cats behind. the floodwater came up pretty high, and the poor man was worried about his cats. once he returned, he found 2 of his cats rescued by an animal shelter. he found his 3rd one under his bed at home, waiting for his return. if the worst thing happens, and they scatter, do not panic. they are probably hiding in the bushes near your house. mines did that one time. lol. also, check to see if cats in your area have been disappearing. my neighborhood has suffered from a series of bobcat/coyote attacks on our local cat population, so our cats come in before dark. i would pay attention to these numbers before letting them live outside. wish you the best of luck!

Ypu need to verify $curl vec F 0$ to determine if there exists $phi$ such that $F nabla phi$. $phi$ is called potential in physicsOnce you confirm there exisrs a $phi$, you can try to integrate partially and combine three to get $phi$I believe $curl vec F ne 0$, so there is no potential.------Expressing position due to gravitational acceleration as a 3-Dimensional differential equationThe easiest thing to do is to start from the gravitational potential$$phi-fracGm_1m_2sqrtx^2y^2z^2$$and use $vec F-vecnabla phi$, or in components:$$F_x-fracpartial phipartial x-fracGm_1m_2,x(x^2y^2z^2)^3/2 m_2 A_x m_2 fracd^2 xdt^2$$with a similar approach for your other components.------syllogism package new counterThere's no need to use a new counter (would be difficult, perhaps)I used another approach, replacing the list in @sylloc command with a special sylloglist which is a clone of enumerate, which provides the counter anyway.The 3rd item is a rule, I have to replace item ... with item there.The list spacing settings have been incorporated into the optional argument of sylloglist.------How to change the html of threaded comments?Could you give a little more info on what you are trying to do?If you want to add your view for displaying comments to a specific thread, please take a look at using panel from contrib ( module allows you to add views (and other components as well) to specific pages, other panels (when using mini panels) etc------Slope of tangent in $(x,y)$ on a circle $K(x,y)inmathbbR^2|x^2y^2r^2$ with initial conditions$r$ is indeed constant (otherwise $K$ wouldn't be a circle)It doesn't matter if separate constants of integration are included on both sides. (Two arbitrary constants can simply be combined: $c_1 c_2$ is still just a constant).$c2$ and $c5$ come from the initial values: $y(1) 1$ and $y(-1) 2$, respectively. In the first case $x1$, $y1$ which gives $c2$. Similarly for the second case------Would a triangle wave have finite or infinite sinusoidal components?a triangle wave is continuousQuote from here: -The triangle wave has no discontinuous jumps, but the slope changes discontinuously twice per cycleHaving the slope change discontinuously also means an infinite range of sinusoidal components.For instance, if you time integrated a square wave you produce a triangle wave but, all the hamonics of the original square wave are still present after the time integration: -------How do I explain to a team that the project they will work on for six months will certainly be cancelled?If the company is making a mark-up of 200%, one way to motivate your developers is to offer them some of that, surely? Say, an extra month's pay on acceptance of the sham product if (as expected) it gets cancelled after six months. You could even give them the option not to participate in the work, but I doubt that there would be many takers------Decomposing quasi-finite separated group schemesAt OP's suggestion, I am moving my comment to an answer. In the original question $U$ was the spectrum of a Henselian DVR $R$ with $K mathrmFrac(R)$.Define $G_1$ to be the union of those connected components of $G$ whose images cover $U$. Then use EGA $textIV_4$, 18.5.11 c) to verify that $G_1$ is a clopen $U$-finite subgroup scheme of $G$------How are files opened in unix?Generally you should read a book like this one to get answers for most such details inside kernel. But, in general, yes, the process is that:Details of directory search for this are very specific for particular VFS. It can be of any kind including memory-only ones (tmpfs), disk-based ones (ext4, etc.), but the common concept of hierarchy of directories is kept in effect------How to make the HT12E transmit (TE to low) only when one or both buttons are pressed?It may be easier than you think; if you look at the data sheet more closely: -So, any button being activated will automatically pull TE low and enable transmission and, in the case when buttons are released (thus deactivating TE), this diagram tells you that the device will continue to transmit the four byte message and thus inform the receiver that buttons are deactivated: -------how to post data of a form to an iframe in lightning component?The browser's same-origin policy prevents a page from accessing content or code in another page loaded from a different origin (protocol port host).You can use postMessage() to communicate between your Lightning Component and the content of the iframe. See this blog post for details.In Spring17, you can also use the Lightning Container Component, but be aware that it is in Developer Preview.------Need sorting method for coordinated, flattenned collection closedThis is not just a sorting problem. You are also updating the YOffset values based on the sorting. So assume the input data is valid(i.e. no missing offsets, consistent type of Value property). Here is the code:Source data:LINQ:Verify the result:The output:Note: I kept sortedByFirstColumn as IEnumerable and unordered, but adjust it the way how your application requires.------Defining real powor of linear operatorThis is impossible. Consider $Vmathbb R$ and $Tx-x$. A linear $T^frac 1 2$ would satisfy $T^frac 1 2T^frac 1 2 x -x$. All linear operators on $mathbb R$ are of the form $Ax cx$ for some $cinmathbb R$. Thus, assuming $T^frac 1 2 x cx$, we get $c^2 x-x$. For $x1$ this gives $c^2-1$ which has no solution in $mathbb R$------Why does water reflect light?EM wave consists of electric and magnetic component. Electric field is responsible for reflection. When EM wave hits the water surface electric component turn molecules of water (H2O is a dipole) Next moment water molecules want to go back in initial position. So they turn back and thus so many molecules at the same time re-emit new EM wave in the opposite direction------Basic tension and equilibrium confusionThe object is not in equilibrium. However, you can still calculate $F$. You know that the string isn't lengthening or shortening, so the net force in the direction of the string is zero.So you can decompose the three forces in the problem into components along the string and components perpendicular to the string, and set the net force along the string to zero------Is there any scrappable junk I should hold on to that could otherwise be used for other purposes?Over due library books can be returned at a library in exchange for book return tokens, you can trade in the tokens for misc items like a camera or toys, and if you have enough you can get a Surgical Magazine.I haven't figured out if subway tokens have anything similar yet so for the time being I've just been holding on to them------Find the coordinates for $v$ in the subspace $W$ spanned by the following vectors:Basically what @PrahLad said, $v a_1u_1 a_2u_2 a_3u_3$ So since $u_1,u_2,u_3$ are orthogonal you can use the formula $a fracy cdot uu cdot u$ or in your case: $alpha fracv cdot u_iu_icdot u_i$So the first one for example will be $fracv cdot u_1u_1 cdot u_1 $ (your calculation here)------What is the purpose of marking the positive terminal of an 50% duty cycle oscillating source?It is just common practice. In reality there is no need, but people like reference points, and things that feel familiar to them. People who have a lot of experience with electronics know that there is almost always a positive and a negative end (even if it is arbitrary and does not matter). Putting a is just a way to make people feel comfortable.
Siemens Is Considering Using Blockchain to Improve the Car Sharing Market
Siemens Is Considering Using Blockchain to Improve the Car Sharing Market
With the emergence of bitcoin, a new secure value transfer method has emerged through its underlying technology blockchain. Since the birth of bitcoin 10 years ago, a large number of mainstream entities have studied various ways to guide the potential of blockchain. Automation giant Siemens is evaluating technologies for various enterprise use cases, including improving the car sharing market.Siemens is following the trend of mainstream giants seeking to integrate blockchains. "We are developing industrial expansion products of blockchain system," Andreas kind, technical director of network security of Siemens, told me in an interview. The use cases mentioned above are related to supply chain, mobility, manufacturing and other fields.Kind explained that when entities are interested in moving towards blockchain, they usually have to go through a period of testing and discovery before they can choose the most effective and applicable use cases. "Siemens is at this stage," he added. Kind said that the company has just completed a period of exploration. "Now we have really entered a set of use cases related to Siemens business." Kind pointed out that Siemens especially wants to obtain the use license of blockchain.Blockchain in the mobile fieldThe director of network security and blockchain mentioned that the mobile field is one of the key applications of Siemens blockchain. Siemens has a separate branch in the mobile field. Siemens mobility, a subsidiary of Siemens AG in Germany, stated on its website that the company is committed to providing "transportation solutions" and integrating "people and goods" Shipped all over the world.Car sharing as an optionKind explained that people living or working in larger urban areas often rely on carpooling rather than undertaking some responsibilities related to owning a car, such as parking, car payment and insurance. According to the details on the enterprise carshare website, carpooling service allows users to rent a car at any time, even as short as an hour. Zipcar is another example of car sharing operation Son.This is a huge change. So in the future, there will be more opportunities around mobile services, not just selling a car. You have seen it in the context of car sharing. People want to go from point a to point B, rather than owning a car and moving, because sometimes it is much more convenient than owning their own car.As king specifically mentioned the "gas card", carpooling does have its difficulties. King said that in the car sharing subscription service, "you don't have to worry about paying parking fees or refueling your car, so all fees are included."However, kind said that sometimes customers may need to refuel their cars. Finding a suitable gas station may be difficult because customers need to refuel at specific gas stations, which cooperate with companies sharing their cars. When customers find a place to refuel, they must use a gas card and attach the relevant personal identification number (PIN) with detailed instructions.Kind pointed out: "this is not only inconvenient for drivers, but also inconvenient for companies, because gas cards will be stolen and sold on the Internet." he explained: "in an industrial environment, you need something, a technology that can bring together different participants who (do not) fully trust each other." "this is where blockchain can add value."Car sharing and blockchainKing explained that sharing cars is an area where Siemens is considering integrating the blockchain. "In this area, blockchain provides a more frictionless way of transaction." he added: "transactions can be car delivery or (simple) carpooling." king also noted many interacting groups, such as brokers, organizations owning cars "Garage provider" and so on. Kind said: "all this should be completely seamless in the process of transaction. Blockchain is indeed a correct technology."At Bosch's 2019 connected world conference, a representative of Siemens explained to me in an email that Siemens's enterprise technical team introduced in detail the concept of "Intelligent Parking Based on blockchain" as a possibility of using blockchain.
Pretty and Cool Halloween Witch Or Dark Fairy Costume Ideas for a 11 Year Old Girl?
Pretty and Cool Halloween Witch Or Dark Fairy Costume Ideas for a 11 Year Old Girl?
Hi there Here is an article I wrote recently when I was asked a similar question. I hope you find it useful. When it comes to girls, there are some standard costumes that you will see year after year at Halloween time. With many of them, they wear the costume year round in creative play. Birthday parties year round are starting to have "theme" costumes, as well, and many of these will fit with those beautifully. Princess - The Disney Princesses are the most popular. With gorgeous dresses that go with Belle, Sleeping Beauty, Cinderella, Snow White and Jasmine, you will surely find one that fits your child and that they will enjoy. Most toy stores carry these costumes year round, so you can find them on sale and stock up for future Halloweens. Ballerina - A very simple costume of a leotard and a tutu. Best used in warmer climates, as Halloween night can get chilly in some areas. I've found that these costumes often come with wings, making the costume more along the lines of a "Fairy Ballerina". Blue from Blue's Clues - no matter what you may think, Blue and Magenta are both girls. Most children know this! Blue can sometimes be worn on little boys, though, and Magenta is quite popular with the girls. Dora the Explorer - What an easy costume to either purchase or make yourself! With a simple pink t-shirt, red shorts, yellow socks and white tennis shoes, you have the costume pretty much complete. Add a purple backpack and some jewelry you find at a dollar store and you little girl can be Dora all year long. Various Animals and Bugs - Little girls love dressing as animals. At Halloween time, black cats and bunnies are popular. Bugs like bumblebees, ladybugs and butterflies are also everywhere! These costumes can be bigger and bulkier than some, so make sure to take into account how heavy it is and how far you are expecting your child to walk. My best advice when costuming your child at Halloween is let them choose what they want. Do not make big plans and create a costume, only to turn around and see they want to buy something "cool" from the store. They are not going to have fun in a costume you force them to wear, which will ultimately ruin your night, too1. how much money should a child get from the tooth fairy for their teeth?i used 2 get a dollar a tooth then i would get a candy bar or soda from the gas station with it so maby 1-2 dollars2. Why we rarely see magic circle during battle in Fairy Tail : Final Series?I found this reddit post from 4 years ago that addresses this issue. Relevant comments from the thread:That might also be the reason why you feel the fights ended more quickly3. If you could do whatever you want with a fairy tale village, what would you do?that sounds like a very fun place to live, you need to add a well of spirits though, you know a central magical area :)4. Are fairy's real? if so, have you ever seen one?Fairies are real but i doubt many people have seen them. They like to stay away from humans i guess5. WHAT AM I??? AM I A VAMPIRE, fairy, mermaid ect...?...Yet another little girl who's read cursed Twilight one to many times. But anyway, none of the things you mentioned are criteria for being any kind fictional creature.6. What colour is Levy McGarden's guild tattoo in Fairy Tail?I think it's white. They show it during the tenrou arc when she goes to get help for Gajeel. And yes it's on the back of her left shoulder blade7. Why will Fairy Tail have 4 consecutive weeks of double chapters?I think this is mainly a marketing tactic, meant to attract more readers to buy copies of the Weekly Shonen Magazine1. When the magazine's copies hit the bookstore, a front cover caption Fairy Tail! Double Chapter inside!! ... and next 3 weeks too!!! (or something on those lines) will draw the buyer's attention, and would likely lead to an increase in sales. Regular readers would buy the magazine no matter what, but the tactic is mainly aimed at two categories of prospective buyers:People are made to believe that they are getting something "extra", which often leads to making a buy decision. This, by the way, is not much different from the "Buy One, Get One Free" offers. It is also quite common for popular TV shows to have "2-hour specials" every once in a while, which is also based on the same "principle" (if you will). Moreover, announcing 4 consecutive editions with double chapters increases likelihood of repeat business. People look forward to buying the next 3 issues as well. Buying 4 consecutive issues will lead to at least a sizeable number of readers "latch on" to the magazine, who would naturally choose to continue buying later issues as well. As for why Fairy Tail gets double chapters so often (as against other mangas), I think it mostly comes down to "because he is Erza Mashima!!" To elaborate, Mashima (and his assistants?) are able to spend more time and/or effort on their manga and can submit two chapters in a week, whereas most other mangakas may not be able to do so due to personal commitments or other reasons. As an aside, he published triple chapters of Fairy Tail for two consecutive weeks a year or so ago. (Chapters 338-340 and 341-343, IIRC)1 Weekly Shonen Magazine is different from Weekly Shonen Jump.
What Should My Sister Put on Her Wedding Registry?
What Should My Sister Put on Her Wedding Registry?
We have all the standard stuff that you need for a house too. I've already owned 3 houses and have moved into a bigger house every time I buy a new one so of course, I have enough stuff. She had her own apartment for the last 3 years. However, she decided she wanted all new stuff so that's what we asked for on the registries. Towels, sheets, comforter, mattress cover, dishes, cutlery, appliances, etc. We had a few nontraditional items on the registry too. Dog bed for our dog (purchased), a new gas grill (yes, somebody bought it), a motorized cooler on wheels (got that too!), a microwave (got it) and stuff like that. Those are just some ideas you can registered for. Go shopping in these stores that have registries and just pick out stuff you want. That's what we did.1. maintenance schedule tracking softwareYou mention Strava: they do that for you. If you register components and parts of your bike like a chain it will show the mileage from the registering date. It might a bit problematic if you have two sets of wheels (like one for rain and another for sunny days)that you use alternatively2. How many wheels are on a boat?Depends on your definition of a wheel and what kind of boat.By the most common definition, there are no wheels on my sailboat. But you could call a "block" with a rotating pulley in it a wheel. This would bring the sailboat up to 12 wheels.If you mean "steering wheels" or the wheel for the helm, again my sailboat has none. It uses a tiller. Some sailboats have just one wheel for the helm. Some of the large sailing vessels had many, because the power needed to hold the helm was far more than one person could exert and power steering did not exist.3. Road Shape for Square WheelsLet Choose a coordinate system so that $Q$ is constrained to move on the line $y=0$. This means $y_Q = 0$ identically.Parameterize $P$ by arc-length $s$. We will assume the wheel is rolling from left to right without sliding. Furthermore, at $s = 0$, $Q$ is located at origin and lies directly above $P$. More precisely,$$(x_Q(0), y_Q(0)) = 0,quadtext and quad begincases ( x_P(0), y_P(0) ) = (0,-b) ( x'_P(0),y'_P(0)) = (1,0) endcases$$After we roll the wheel for a distance $s$, $P$ moved to $(x_P(s), y_P(s))$. The tangent vector and upward normal vector of the bump at that point equals to $t = (x'_P(s),y'_P(s))$ and $n = (-y'_P(s), x'_P(s))$. Since the wheel is rolling without sliding with respect to the bump. One can reach $Q$ from $P$ by a move along direction $n$ for a distance $b$ followed by a move along direction $-t$ for distance $s$. This leads to following ODE$$0 = y_Q(s) = y_P(s) - s y'_P(s) b x'_P(s)$$Together with the constraint $x'_P(s)^2 y_P'(s)^2 = 1$ and given initial conditions, one find:$$ begincases x_P(s) = bsinh^-1fracsb y_P(s) = -sqrts^2b^2 endcases quad iff quad begincases x_P(s) = bt y_P(s) = -bcosh t endcases quadtext where quad t = sinh^-1fracsb $$ Let $t_0 = sinh^-1(1) = log(1sqrt2)$. The two endpoints of the bump corresponds to $s = pm b iff t = pm t_0$. At those points, $y_P(s)$ reaches its lowest value $-sqrt2b$. The area under the bump (but above this $y$) is given by the formula:$$beginalignint_-b^b (y_P(s)sqrt2b)x'_P(s) ds &= b^2 int_-t_0^t_0 (sqrt2 - cosh t) dt = 2b^2 left(sqrt2t_0 - sinh t_0ight) &= fraca^22 left(sqrt2log(1sqrt2) - 1ight) endalign $$ UpdateAbout how to solve the ODE, differentiate both equations by $s$, one get $$ begincases y - s y' b x' &= 0 y'^2 x'^2 &= 1 endcases quadstackrelfracddsLongrightarrowquad begincases -sy'' bx'' &= 0 y'y'' x'x'' &= 0 endcases $$ Comparing coefficients for $x''$ and $y''$, we find there is a function $lambda(s)$ such that $$ (x',y') = ( blambda, -slambda ) $$Since we want $x' > 0$, the normalization condition $x'^2 y'^2 = 1$ fixes $lambda$ to $frac1sqrts^2b^2$. Integrate above equation by $s$ will give us the desired solution.4. Helpful Spring Cleaning & DIY Car Detailing Tips | Fredonia Chrysler Dodge Jeep RamWinter is finally taking its final breaths, and with it comes warmer and more enjoyable weather. But just because winter's wrath is weakening does not mean your car is out of the woods. Here are some useful spring cleaning tricks and DIY car detailing tips you can use to ensure your vehicle is prepared for the higher temps and longer road trips you are bound to take. Road salt is no joke-it can lead to car rust and all sorts of disgusting automotive ailments. As winter ends, you should ensure you are giving your car a full-on wash. Start by moving your car into the shade. Using a high-pressure hose or pressure washer, blast off the chemicals from the undercarriage and wheel wells. Do it again, just as a precaution. Take to the paint with a rinse and a few swipes from a soft sponge or microfiber cloth. Use a non-abrasive car-wash soap and wash one side at a time so that you can rinse the soap off before moving onto the next. Repeat if needed with clean water, and do not forget the wheels. Most mats are made of a special carpeting material-resilient, yes, but they are not typically stain-proof-and will require a thorough wash-n-scrub session. First, remove your mats and pick or vacuum up any loose debris like rock salt or wrinkled-up straw wrappers from your car's floor. Next, dilute stains with cold water, blotting with a rag. You can make a solution of water and dishwashing solution, but for the best results, use a specialty spot cleaner and follow the manufacturer's instructions. Here are some other handy cleaning tricks to help remove different types of stains: You can use small amounts of paint thinner-do perform a test spot first-to remove grease spots. Saturate the stain and cover with iodized salt. Let this mixture sit for a few minutes or until the grease looks to have been absorbed by the salt, then vacuum. If your pen exploded and left a large stain on our floor sometime during the winter, grab a can of hairspray and blast the stain. Once dry, wipe or brush the stain away, repeating the process until the ink is out. We wo not question why there's blood on your carpets. Instead, just use a laundry stain pen and ice-cold water. Dry laundering starch and water works well, too. If you are like most of us car owners, you've no doubt spilled a mocha latte or two on your way to work. To reduce the visibility of those pesky stains, apply cold water and glass cleaner, then blot. Carsickness can get the best of anyone. To remove the sights (and smells) of such a disaster, wash the area with mild soap detergent, warm water, and some club soda. Cover the saturated area with baking soda for additional odor absorbency. Lay your car mats out. Grab a brush and create a solution of hot water, dish soap, and white vinegar. Scrub the mats and allow to dry. Repeat if needed. For your car floors, you can use a steam cleaner to lift and treat most stains, or the same solution and process as mentioned above, taking care not to use too much water. Finally, apply standard shoe wax/polish to your mats to give them that new-car glisten. The harsh winter conditions and temperatures can do a doozy to your wipers. Allow the techs at our Fredonia CDJR service center to install your wipers, or check online to ensure sure you are investing in a quality set that fits your vehicle's make and model. A clean car is one thing, but why not have a clean and reliable car? To ensure your vehicle is ready to pile on some warmer-month mileage, bring it into our Fredonia service department. Our specialists will gladly change your oil and fluids, rotate and align your tires and wheels, and perform recommended maintenance.
