A lower voltage may not affect your electronics' performance, but you should always check with your device's user manual to see if a battery voltage or chemistry is compatible. Yes, rechargeable D batteries use NiMH (nickel-metal hydride) or LiPoly (lithium-polymer) chemistries and have an 8.4V voltage compared to the typical 9V of primary variants. At least, it is so long as the current is low enough that the reaction rates can sustain it.Frequently Asked Questions Are there rechargeable 9V batteries? The battery voltage is held up in this way. When you place the battery in service and the accumulated charges disperse rapidly into a circuit to motivate a current to move (very rapid process that is only very rarely discussed in electronics), current in the circuit occurs and charges at the two battery terminals will recombine and this will disturb the field gradient inside the battery, lowering it, and thus the equilibrium state shifts out of that equilibrium with a renewed, slight preference for one side of the chemical equation, again, and electrons are moved through the inside of the battery until things are back in equilibrium. This sets the unloaded battery voltage that you'd measure using a high impedance device designed for that purpose. The increasing electric field gradient increasingly retards the chemical reaction rate, too.Įventually, the early preference for one side of the balanced reversible chemical reaction for moving electrons from the cathode to the anode has diminished enough so that the other side of the balanced chemical reaction occurs at the same rate and the battery finds an equilibrium state. This continues for a while and as it does an increasing field gradient (electric in nature) develops because of the accumulating charge differences. When all the materials are first assembled (for example, the diluted sulfuric acid is first poured into a lead-acid wet cell), the reversible chemical reactions inside the battery cell have a preference to start removing electrons from the cathode and adding electrons to the anode. Suppose you fabricate a chemical battery, using any of a variety of practical arrangements. (I'll also talk about a rechargeable battery case, with reversible reactions - although that's not critical to what I write below, it makes it a little easier for me to write.) And keep in mind that the usage of anode and cathode as a chemist applies them may at first seem confusing to someone in electronics. I'll just talk generally about the chemistry. Hence, how does a 9V battery generate 9V for an extended period of time? Obviously reality doesn't match my expectations but the saying "voltage is pressure current is flow" doesn't really explain this situation either. I conclude the potential difference must be less than 9V significantly. If electrons are flowing from the negative terminal through the light bulb and back to the positive terminal then how is it possible to have a 9V voltage difference between terminals for the entire hour? After 30 minutes wouldn't I be left with 4.5V worth of electrons? Half of my electrons have flowed from the negative terminal to the positive terminal. In one hour the battery runs out and the light bulb turns off. So lets say I connect a light bulb that consumes 500 mA at 9V. In a 9V battery the manufacturer might label the battery has 500 mAh (it can produce 500 mA for one hour.) I conclude there are enough electrons in this battery to create 500 mA for 1 hour. Voltage is a difference in the amount of electrons between 2 points. We can quantify the number of electrons moving past a point into a measurement called current. Electrons moving is what we call electricity. I recognize that all things are made up of atoms. In my career I have mostly ignored this question and just taken it for granted that if a 9V battery says it produces 9V that it will produce 9V until it runs out of "battery" but curiosity finally caught up with me and I want more details.

I can then get back to working with Houdini So, Houdini, make an option to use Apprentice for commercial content creation for Unity. We as Unity users can only benefit from it. They have missed the main wave of Unity's rise, but they can get on some of the ripples if they act now, and those ripples can be quite lucrative for them. I hope they come to their senses and do so now. Houdini, I feel, pioneered many of today's standard content creation features.īut they have lost much ground to other options. They have missed an enormous opportunity to get Houdini into the hands of literally millions of indie developers (and potential upgraders). I switched to Unity when it became available for Windows and have kept an eye out for Side Effects to do like wise for Unity. Side Effects gave an options for Torque users long ago to use Houdini Apprentice for content creation commercially with Torque. Or perhaps I am wrong and the price of houdini engine will be reasonable, while the use of ready made parametric assets will eliminate the steep learning curve difficulties. What I say is that there are technologies that are less relevant for the solo-small team devs, because of their cost - learning curve and chances are, Houdini engine will fall in this category, alongside with substance designer, scaleform and others. I consider Houdini a serious player in DCC and without doubt, this move, if successful, will help to further improve its position as an Autodesk alternative.

There's also a built-in lens cover to protect it when it's in your bag or pocket, which helps make it even more portable. For example, you get a two-component retractable lens that makes storage a bit easier, as well as an f-stop of 60 mm. The Instax Mini 7+ is very similar to the 7S, but boasts a couple of quality-of-life improvements. Fujifilm Instax Mini 7S - you'll know that the Mini 7S is a great instant camera to grab. If you read our instant-print face-off - Polaroid OneStep Flash vs. Why you should buy the Fujifilm Instax Mini 7+ You can even grab it for cheaper than usual from Walmart, as it's just $49 rather than the $67 it normally goes for. It's small, cute, and relatively inexpensive, yet gives you the opportunity to play with instant photos. Take the Fujifilm Instax Mini 7+, for example. For those in the know, though, instant cameras provide an interesting retrospective and stylistic choice that a filter can't easily recreate. Many folks might write off instant cameras, especially with everybody having a high-end portable camera in their pocket that primarily serves as their phone. As for the video, well, sadly, it's not as impressive, at least in terms of advancements in image quality, and while it can do 8-bit 4K at 30 frames per second, it's no longer ahead of the pack in that regard, like the Panasonic Lumix GH5 is with its 400Mbps 10-bit codec and 60-fps 4K. Interestingly, the a7 III manages to do an excellent job at both low and high ISOs, the latter of which can go as high as 51,200 non-boosted, which, granted, adds a lot of noise, but noise reduction helps with that. It has excellent dynamic range, low-light performance, and high-speed performance, and the full-frame sensors make the images look absolutely stunning. The Sony Alpha a7 III is a camera with so much tech that it might as well be three different cameras. While it usually goes for a whopping $2,200, Best Buy had brought it down to $1,900, and while that relatively doesn't seem like much, you could always spend the $300 savings on a new lens. Of course, many folks may not realize that Best Buy has some fantastic deals on high-end photography gear, such as this Sony Alpha a7 III mirrorless camera. There are a lot of great Best Buy Black Friday deals going on right now, and whether you're looking for TVs, laptops, or even headphones, there's a little something for everybody.

SNFs provide the best careįortunately, in terms of quality outcomes, SNFs continue to lead the pack, according to data Trella Health presented this week. Success depends on finding facilities that, based on a rigorous evaluation process, put the patient in the best position to have the best outcome for themselves or their loved one, he said. “For now we are very much committed to on the post-acute care side.” “We have seen firsthand … there are unique skills and attributes and talents that you bring to the table that we do not,” he explained. There are things that experienced skilled nursing operators can provide that no one else can. Desai, medical director for value innovation at Yale-New Haven Health, said during the hospital executive perspective portion of the state of the industry panel at the Synergy Summit this week. “If a facility is willing to take risk as we continue on this arc from fee-for-service to value, if we can find partners on the post-acute side that want to take some risk with us or embed themselves in a different kind of relationship with us … that signals to us that facility’s overall alignment with what we’re trying to do,” Dr. When developing an integrated network of care, these groups are looking for facilities that always pick up the phone, show up for the meeting and are engaged with the health system as a whole. She is not alone in seeing SNFs as high-quality partners. “I think starting an ACO in the pandemic in a lot of ways allowed us to keep our conversations going and I don’t think they ended during the pandemic.” When a patient falls … we can’t be a provider in all those spaces and so it makes sense for us to find true partners in the community,” she explained. “For us, post-acute care becomes the eyes and ears of our patients. It also requires a “total system” approach to effectively balance multiple fluctuating energy sources, consumption levels, and new renewable technologies. It requires an advanced level of computing to manage and optimize the highly distributed intermittent loads introduced. The need for more power is met by building another power plant.Ī smart grid is a highly distributed network of clean, renewable energy deployed at the edge of the existing grid. Traditional energy grids allow for a one-way power flow from centralized sources like coal, nuclear, and gas to places of consumption such as homes, businesses, and data centers. The current energy grid structure provides little flexibility or support for new renewable technologies. Thus, allowing them to control demand, safeguard the distribution network, save energy, and drive down costs. The smart grid electricity network lets devices connect. Creating a smart grid is vital in delivering energy resources in the face of supply disruptions while optimizing usage for a healthier planet. The energy grid is where the crises mentioned above meet. One such trend we discuss in this post is “Smart Grid technology,” which allows electrical networks to operate more efficiently. This is a project where we can leverage our solutions for sustainable cities and unique Environment Portfolio to help achieve the project’s low carbon objectives and deliver affordable electricity.As energy crises and prices sharply increase, we are witnessing some amazing innovation trends in the energy storage sector. Siemens is also part of the team delivering Western Power Distribution’s Project BRISTOL) and works as a partner to Electricity North West (Project CLASS) in the current round of submissions to Ofgem.Ĭolin Henry, business development manager at Siemens said: "We are delighted to be part of the Customer-Led Network Revolution project to develop one of the most ambitious smart grids ever in the UK. Siemens is part of the GB Smart Grid initiative and was a partner in UK Power Networks Low Carbon London project 2010-2012. Siemens impressed us with their understanding of our needs, offering the right solution at the right price." Jim Cardwell, head of regulation & strategy at Northern Powergrid commenting on the contract award said: "We needed a solutions provider who could deliver an innovative solution, which encompassed experience of working with complex system integration, technology, as well as an ability to meet our demanding project deadlines. The system uses a hierarchical approach taking decisions at substation level and in the control centre to optimise operation of the network by use of energy storage, enhanced voltage control, real-time thermal rating and demand response. Siemens’ system is to be installed in Northern Powergrid’s control centre for its advanced network optimisation algorithm. This is the first time Siemens will use this system in the context of a Distribution Network Operator (DNO) in the UK. Siemens will base its solution on its Spectrum PowerCC network management system technology to deliver the smart grid scheme. The project involves Siemens in delivering the Grand Unified Scheme Control System (GUS control system), a system which brings together multiple elements, allowing them to operate as a smart grid. Siemens will design, install, commission and support the comprehensive smart grid scheme, which will control 6MWh of energy storage. The Customer-Led Network Revolution (CLNR) project, awarded to Northern Powergrid as part of Ofgem’s Low Carbon Network Fund can help lead the way in which the grid will be transformed. Smart grid is key to this transformation as it will allow the network to deliver low carbon electricity where and when it is needed. Meeting these targets will involve significant shifts in the way the UK delivers energy for heat and transport from carbon intensive methods (gas and oil) to a low carbon electricity network. The project, which covers North East England and Yorkshire, will enable Northern Powergrid and the wider UK electricity industry to prepare for transformation of the electricity networks to help the UK meet its 2050 low carbon commitments. In contrast, using tau, the pizza-slice angle is simply τ/8. That makes things confusing: For example, the angle at the tip of a slice of pizza - an eighth of a pie - isn’t π/8, but π/4. Pi is the number of radians in half a circle, not a whole circle. The simplest way to see the failure of pi is to consider angles, which in mathematics are typically measured in radians. But the debate tends to reignite every year on March 14, which is celebrated as Pi Day for its digits: 3/14. In 2001, mathematician Bob Palais of the University of Utah in Salt Lake City published an article in the Mathematical Intelligencer titled “ π is wrong!” The topic gained more attention in 2010 with The Tau Manifesto, posted online by author and educator Michael Hartl. Sometimes known as tau, or the symbol τ, the quantity is equal to a circle’s circumference divided by its radius, not its diameter. These critics - including myself - advocate for an arguably more elegant number equal to 2π: 6.28318…. But some contend that replacing pi with a different mathematical constant could make trigonometry and other math subjects easier to learn. But, as some mathematicians have argued, the mathematical constant was poorly chosen, and students worldwide continue to suffer as a result.Ī longtime fixture of high school math classes, pi has inspired books, art ( SN Online: 5/4/06) and enthusiasts who memorize it to tens of thousands of decimal places ( SN: 4/7/12, p. Pi, known by the symbol π, is the number you get when you divide a circle’s circumference by its diameter: 3.14159… and so on without end. I don’t mean that the value is incorrect. As a physics reporter and lover of mathematics, I won’t be celebrating Pi Day this year.
