Besides bigger challenges on economy and foreign policy issues, Obama has also to cover much more sectors which have postponed crucial decisions till the election of new President. They all require immediate attention because they are going to lose a lot along with the delay. As science and technology is one of them, it is our duty to estimate what he can bring to science and act or react accordingly. Obama’s speeches were very positive on issues with science and what I liked most among them is his “planet in…

Use of Traction Control System
A traction control system (TCS), on current production vehicles, is typically electro-hydraulic systems designed to prevent loss of traction and therefore the control of the vehicle when the driver applies excessive throttle or steering. Although similar to electronic stability control systems, traction control systems do not have the same goal. The intervention can consist of any, or all, of the following: Retard or suppress the spark to one or more cylinders Reduce fuel supply to one or more cylinders Brake one or more wheels Close the throttle, if the vehicle…
Read MoreCall Control Or Call Processing
In telephony, call control refers to the software within a telephone switch that supplies its central function. Call control decodes addressing information and routes telephone calls from one end point to another. It also creates the features that can be used to adapt standard switch operation to the needs of users. Common examples of such features are “Call Waiting”, “Call Forward on Busy”, and “Do Not Disturb”. Call control software, because of its central place in the operation of the telephone network, is marked by both complexity and reliability. Call…
Read MorePlan 9 from Bell Labs
Plan 9 from Bell Labs is a distributed operating system, primarily used as a research vehicle. It was developed as the research successor to Unix by the Computing Sciences Research Center at Bell Labs between the mid-1980s and 2002. Plan 9 is most notable for representing all system interfaces, including those required for networking and the user-interface, through the file system rather than specialized interfaces. Plan 9 aims to provide users with a workstation-independent working environment through the use of the 9P protocols. Plan 9 continues to be used and…
Read MoreAdvantages and Disadvantages of Die-casting
target=”_blank”>Die-casting is the process of forcing molten metal under high pressure into mold cavities. Most die-castings are made from nonferrous metals, specifically zinc, copper, and aluminum based alloys, but ferrous metal die-castings are possible. The die casting method is especially suited for applications where a large quantity of small to medium sized parts are needed with good detail, a fine surface quality and dimensional consistency. This level of versatility has placed die-castings among the highest volume products made in the metalworking industry. In recent years, injection-molded plastic parts have replaced…
Read MoreGraphene: the wonderful material
When you look at its lattice deeply through some lattice viewing method, you will look at a honey comb shaped crystal lattice, standing there with equal dimensions and spacing. This is called Graphene, the material made of carbon atoms and their bonds. Graphene is a wonder material for the scientists working on nano technology. The specialty of Graphene is that it is the thinnest possible material in this world. If you could pile up around 25,000 sheets of Graphene, one over the other, they make up to just the thickness…
