The result will have r in the X register and the angle in the Y register. The next program, Rect > Polar, will be an example of this.Ĭonvert Rectangular Coordinates to Polar CoordinatesĮnter the y coordinate then the x coordinate. When all the calculations are finished, I store the results into X, Y, and permanent memory registers (if necessary). I use temporary registers to store and execute immediate calculations. In more complex programs, I start by making copies of X, Y, and any other required registers into temporary registers. If we treat Earth as a sphere, it's volume would approximately be 260,711,882,973.332 cubic miles. Test example: The radius of Earth is approximately 3,963 miles. Multiply X By Pi (scroll down the possible list of values to select π). Please pay careful attention to the order of the program steps. This program takes the radius in the X register and calculate the volume of the radius. The volume of a sphere is V = 4/3 * π * r^3, where r is the radius. You can stop, even invoke the error condition at any time by inserting a Stop or Error command, respectively. There are no loop commands in PCalc (as of this blog post). It may take practice to get the Skip commands correct. There is a plain Skip command to arbitrarily skip a number of commands. Skip (number of steps if the comparison is true) Value (register or value that is compared) Skipping Functions: PCalc allows for Boolean comparisons of values.Ĭommand: Skip (what has to happen for the next commands to be skipped) Let A and B be registers, B can also be a value.Ī To Power Of 1/B: Bth root of A stored in A (principal root) Value (value of a designed register or specified value) Two Argument Commands: This is the arithmetic operations, power commands, and the Set command. x must be positive, but does not have to be an integer.

This also includes several number operations: ![]() This includes trigonometric and logarithmic commands. One Argument Commands: A command operates on a register and stores the result in that register. This includes angle setting (Degrees Mode, Radians Mode) and base setting (Decimal Mode, Octal Mode, Binary Mode, Hexadecimal Mode). Mode Commands: they change the mode of PCalc. PCalc also has 10 permanent memory registers (labeled Memory 0 through Memory 9), 16 temporary registers (labeled Register 0 through Register 9, then Register A through Register F), and a tax register.Įverything is done in a sequential manner.

To recruit these fanatics, invitations were extended to DEW fans online. The next step was to create DEW Labs, an online community composed of the brand’s most loyal, hard-core fans. Three finalists emerged from the grassroots voting and the feedback from brand fanatics. ![]() The artwork was unveiled at a July event in Denver, and included artists such as John Fellows, Jeremy Charles Burns, Delton Demarest, Jolt, Max Kauffman, Scot LeFavor and Kelly Potter. The boxes themselves were one-of-a-kind: They unfolded into works of art, each designed by an up-and-coming artist commissioned by Mountain Dew. This footage then posted to YouTube and Facebook. ![]() Home-tasters then asked to record themselves sampling the flavors and choosing their favorite. Recipients then selected from among hundreds of brand fans who submitted video clips of up to 12 seconds explaining why they deserved a kit. More than 3,000 tasters texted their ballot.Īt the same time, 50 brand fanatics received unique DEW in a Box home-tasting kits. Participants could vote on site using touch pads, or they can text in their vote later, referring to a card marked with their flavor choice. This mobile tour drove more than 1,100 fans to the Facebook page during the four-week program. These visitors were also direct their opinions to YouTube, Facebook and Twitter to watch the taste-experience videos and comment on their own experience. Visitors were encouraged to document their experience in a video booth at the truck stop, describing which flavors they liked or disliked. Fans came from miles away to get a taste-and more than 1.5 million people attended the events. Matching with a “laboratory” theme, each astounding flavor were labeled with a coded number, and samples was presented in test tubes. In July 2009, the second DEWmocracy campaign began with a tour of a team of DEW Labs trucks traveled to 17 markets in 12 states, giving consumers from Chicago to Charlotte the chance to sample the seven flavors. ![]() Phases Phase 1: From Seven Flavors To Three
![]() Unlike other birds, however, the shoebill stork doesn’t have any webbing in between the legs. As you can see from its looks, the shoebill stork comes with very long, black-ish legs. One thing to consider about the shoebill stork is the fact that the eyes are grayish-white or even yellow in color. That helps the bird catch fish with ease and eat it without a problem. Another thing to consider here is that the shoebill stork mandible has a very sharp edge. The bill color is yellow, but in many cases it does have some blotchy dark spots. ![]() On top of that, it has a curved, sharp hook towards the end. The shoebill stork bill is their prominent feature and it’s very similar to a wooden shoe. That crest is covered, and the juveniles tend to have a darker shade most of the time. This will sometimes appear in the form of a crest. When you see the shoebill bird, you will notice some tuft of feathers on the back of their head. When it comes to their underparts, they have light touches of gray, which is something to take into consideration. Their primaries are black-tipped, while their secondary comes with a green tint. ![]() Another thing to consider when it comes to the shoebill stork is the fact that it has a blue-gray, slaty plumage. Males are usually taller than females and they will also have a much longer bill. Most of the time it will be anywhere from 110 to 140 cm in height. The shoebill stork is amongst the largest birds in the world.

We don’t blame you- they can be awfully troublesome to carry around. ![]() How Sophia the Robot works is that she has deep neural networks in her “brain” that aid her in discerning humans’ emotions. This is essentially what Sophia the Robot is capable of doing. Imagine all the humanoid alien movies you have seen where there is an unavoidable montage of the main character trying to fit in amongst humans by learning their expressions, emotions, and thoughts. There is a learning curve for Sophia the Robot. Recognize Human Faces Photo by geralt via Pixabay Still, we do know that this is not a fixed software, since her expressions are being built around her day-to-day interactions with human beings and her curiosity in understanding them. Thus, the public is not specifically sure of how Sophia matches her facial expressions to her emotions. Sophia the Robot’s code is a space of wide contention among those in AI because it is not an open resource. In her famed speech at the 2017 Future Investment Initiative Conference, she demonstrated that she can make faces that show whether she is angry, sad, or happy. Her code allows her to socialize with humans by mimicking human behaviors and emotions. Sophia the AI Robot is a social robot and reflects human expressions right back to you when you are in conversation with her. What Can Sophia the Robot Do? Photo by geralt via Pixabay Supporters push Saudi Arabia to the forefront of international technological advancements, while the latter begs this question: How far are AI rights going to go from here? This historical moment was met with awe and criticism. The Middle Eastern powerhouse granted Sophia the Robot this distinction at the 2017 Future Investment Initiative Conference in Riyadh, Saudi Arabia, catching her by surprise. Specifically, a citizen of Saudi Arabia as of 2017. But as of today, Sophia is very much a citizen of our world. This sparked controversy at the time and continues to charge conversations about AI rights. Sophia the Robot is the first robot granted citizenship to any country worldwide. What Country Is Sophia the Robot a Citizen Of? Before anything else, we want to tell you the biggest stark difference between Sophia and you. Her advanced Artificial Intelligence (or AI) abilities challenge what it means to be “real” and to be human that you can’t help but ask if Sophia the Robot is “real.” With so many AI trends today, AI robots are still perhaps the most shocking. She is several hypothetical conversations come to life. ![]() Its capabilities surpass any human’s, and it can keep updating its repository of data and information as much as it wishes to. It occurs at a shorter amount of time than our brains single-handedly can. This goes beyond simple AI inventions such as Discord Bots or virtual assistants. Sophia the AI Robot has intelligence systems that can process large data and information. Sophia the Robot Is a Super Intelligent Robot, but What Is Superintelligence? Photo by SM5_7114 on Flickr She learns and adapts to human behavior to become more human and work with humans better. Sophia the Robot, albeit programmed to be like humans, does one of the most important functions of the brain: learn. Hanson Robots envisioned her to help humans in building their homes, their cities, and even their basic principles. These tenets fueled the creation of Sophia the Robot. Hanson was a sculptor and material researcher at the Walt Disney Imagineering Laboratory when he decided to go on a quest to create what he called “genius machines.” These machines would have human capabilities such as intelligence, wisdom, and compassion. Sophia the Robot is CEO David Hanson’s most successful AI yet. Who Created Sophia the Robot? Photo by SazzadHossain via Wikimedia Commons Hanson designed the famous AI robot to be humanity’s companion. You can see the tangled wires inside of her physique, which Hanson claims is a constant reminder to us humans that Sophia the Robot, is, in fact, still a robot. Perhaps the most disturbing (or wondrous) part of Sophia the Robot’s physical attributes is her exposed head. Her fluttery eyelashes and picture-perfect eyebrows? Glued on. Her skin has a patented rubber design and can stretch around enough to help create her facial expressions. ![]() In terms of rubber physicality, Hanson modeled her after Audrey Hepburn and his wife. Little Sophia, her tiny spin-off which we will discuss later, aims to promote STEM education for girls. Since her debut in 2016, Sophia the Robot has appeared publicly to talk about AI rights and opportunities.

![]() If the base voltage is equal to the emitter voltage then the transistor is in OFF state. ![]() Here the base terminal and collector terminals always contain positive voltages with respect to emitter terminal. Here both the loads RB and RL can limit the current flow through the corresponding terminals. The collector terminal connected to the voltage VCC through the load RL. In the above circuit connections we observed that the supply voltage VB is applied to the base terminal through the load RB. The working of NPN transistor is quite complex. Here the collector terminal always connected to the positive voltage, the emitter terminal connected to the negative supply and the base terminal controls the ON/OFF states of transistor depending on the voltage applied to it. The above figure shows the NPN transistor circuit with supply voltages and resistive loads. Now let us see the operation of the NPN transistor with explanation. In this structure we can observe the three terminals of transistor, circuit currents and voltage value representations. The above figure shows the symbol and structure of NPN transistor. The NPN transistor is mostly used for amplifying and switching the signals. The NPN transistor has three terminals – emitter, base and collector. Generally the NPN transistor is the most used type of bipolar transistors because the mobility of electrons is higher than the mobility of holes. The flowing of these electrons from emitter to collector forms the current flow in the transistor. Here the majority charge carriers are the electrons. The NPN transistor consists of two n-type semiconductor materials and they are separated by a thin layer of p-type semiconductor. NPN transistor is one of the Bipolar Junction Transistor (BJT) types.
