Basic Triac and SCR Projects and Circuits by Lewis Loflin This page will discuss basic triacs and SCRs. A triac is a bidirectional, three-terminal dual, back-to-back Thyristor (SCR) switch. This device can switch the current in either direction by applying a small current of either polarity between the gate and one of the two main terminals. The triac is fabricated by integrating two thyristors in an inverse parallel connection.
1. Create a Photorealistic Car Render using 3DS Max and Vray Whenever you see highly realistic images of CG cars, you may think that it is an incredibly difficult process to arrive at such a high quality result…this is not actually the case. In this tutorial, Sumeet Gupta will show you how easy it can be to create a photorealistic car render using 3DS Max and Vray, as long as you know the right steps. 16 Awesome Car Modeling tutorials for 3ds Max
But does weeding out genetic maladies imply the term "designer?" As a person who has a family history of hyper-tension, cancer(s), heart disease, ADHD, etc... I feel morally obligated to make sure that the genetic information that promotes those maladies would be removed/switched off in my progeny. However, I do not believe that I have the right to choose the hair/eye color, height, etc... of my progeny. These Unresolved Ethical Questions Are About to Get Real
Would it be boring if we could live forever? Some futurists predict that we'll be able to halt the aging process by the end of this century — if not sooner. The prospect of creating an ageless society is certainly not without its critics, with concerns ranging from the environmental right through to the spiritual. One of the most common objections to radical life extension, however, is the idea that it would be profoundly boring to live forever, and that by consequence, we should not even attempt it. So are the critics right? Let's take a closer look at the issue and consider both sides. To help us make sense of the problem, we spoke to two experts who have given this subject considerable thought: Bioethicist Nigel Cameron, the President of the Center for Policy on Emerging Technologies, and philosopher Mark A.

TPE sur le son : conversion de l'onde en signal électrique 1) Structure générale L’oreille interne est composée de deux parties principales appelées respectivement labyrinthe osseux et labyrinthe membraneux. Le labyrinthe osseux est une cavité creusée directement dans l’os temporal. Sa forme singulière est composée des canaux vestibulaires, sortes d’arcs impliqués dans la localisation dans l’espace, et de la cochlée, tube enroulé sur lui-même qui analyse et transmet les sons au cerveau.

From Simons Science News (find original story here). Alice and Bob, beloved characters of various thought experiments in quantum mechanics, are at a crossroads. The adventurous, rather reckless Alice jumps into a very large black hole, leaving a presumably forlorn Bob outside the event horizon — a black hole’s point of no return, beyond which nothing, not even light, can escape. Conventionally, physicists have assumed that if the black hole is large enough, Alice won’t notice anything unusual as she crosses the horizon. In this scenario, colorfully dubbed “No Drama,” the gravitational forces won’t become extreme until she approaches a point inside the black hole called the singularity.

GravityLight … the lamp powered by sand and gravity. Photograph: GravityLight The problem of bringing light to remote parts of the developing world has been tackled in the past with everything from solar-powered lamps to wind-up devices and rechargeable batteries – all of which require relatively expensive kit or physical effort by the user.

Wonderwall Studios uses natural materials, real and authentic. The wall is constructed using separate tiles. These tiles are shaped in a way that, after mounting, no connection lines will be visible. Wonderall Studios designs can be used for multiple purposes, wall panelling, furniture design, ceilings etc. Naturally the wooden wall is great for acoustics. Current collection consists of three designs: Brooklyn, Parker and Wheels. materials

TetraBox Light by Ed Chew Liquid to Light Designer Ed Chew takes a green step in the right direction with the TetraBox lamp, a light object made from discarded drink packets that would have otherwise ended up in landfills already packed to the brim. The design is achieved by unfolding the packets and refolding them into hexagonal and pentagonal sections that are then pieced together to form a geodesic sphere or any other desired shape. Here, the Epcot-like ball makes an attractive overhead light and casts an impressive web of shadows and shapes on the surrounding space. Designer: Ed Chew
