The Inorganic Chemistry of Carbon Inorganic Carbon For more than 200 years‚ chemists have divided compounds into two categories. Those that were isolated from plants or animals were called organic‚ while those extracted from ores and minerals were inorganic. Organic chemistry is often defined as the chemistry of carbon. But this definition would include calcium carbonate (CaCO3) and graphite‚ which more closely resemble inorganic compounds. We will therefore define organic chemistry as the study

Argon (Ar) is a noble gas found in Group 0 on the periodic table. It gets its name because of its chemical inertness and comes from the Greek root ‘Argo‚’ which means lazy. This is because Argon doesn’t react well with other elements. The atomic number of Argon is 18 making it a member of the helium group of elements which are also called noble‚ or inert‚ gasses and are non reactive. Its electronic configuration is: 1s2 2s2 2p6 3s2 3p6 The outermost shell‚ shell number three‚ has a completely

3.3 Hardware Assembly The next part is assembling all the components together. The Raspberry Pi 2 (in this case) contains a single 40-pin ex-pansion header labeled as ‘J8’ providing access to 26 GPIO pins[1] which is illustrated in Fig. 4. Fig. 4.Raspberry Pi J8 Header Since Pi4J will be used as an external library which enables us to control the GPIO pins using Java Fig.5 illustrates the GPIO pinout using the Pi4J [18] numbering scheme.

Convergence of IP-based Networks Most computer networks based on IP are all pervasive today. Every department‚ building‚ branch of an organization requires and maintains a full-fledged Local Area Network (LAN) for inter-connecting computers. The IP Network can operate on a variety of media – Copper‚ Fiber and wireless. So‚ since they have become inevitable and dominant‚ the other services (voice and data) have been redesigned to run on this network. Before establishing a converged network‚

Although Zigbee implements a wide assortment of security measures‚ there are still a variety of vulnerabilities and attack methods that can be used. These attacks and how they can be carried out will be described in this Section. The first and possibly easiest attack to implement is the denial of service attack. These types of attacks overload the network such that service is denied to the network’s end users. In a typical wired network this is accomplished by having a huge number nodes simultaneously

I believe that the importance of correct programming and setting up of part is very important in today’s CNC manufacturing world as you are producing very precise components that need to be produced first time‚ every time or this is bad news for the company because of loss profits‚ scrap material and expensive repair costs. So ensuring correct programming and setting up of CNC machines is critical. The main reason for needing to produce accurate programing codes to the right specifications is to

In this presentation‚ the author has explained different metrics and there attributed used to measure software. A person can only measure and represent it in number when he knows something about it. On the other hand‚ if has no idea about it then he doesn’t have any idea about it [1]. There are two types of software complexity metrics. One gives the efficiency of the machine while running the software which is called as computational complexity. Another one is giving us the factors which affect the
