Multiplexing

Optical fiber thin as hair is everywhere on this planet, carries an enormous amount of information from place to place. There are a number of desirable characteristics of the optical fiber for conveying this information. They have the ability to carry large amounts of information, a low cost and have the immunity from electrical wiring and wireless communication link a number of disturbances that can afflict. Advantages of optical fibers for transmitting information from place to place, it…

The Distributed Network Protocol version 3.3 or the DNP 3.3 is a protocol used in the telecommunication between the master station, RTU’s (Remote Telemetry Units) and other Intelligent electronic devices. The DNP 3.0 was introduced to communicate between systems in the electric utility, waste and water, oil and gas and security industries(Clarke, Reynders, & Wright, 2004). Created by Harris controls division for the use in electrical utility industry, the DNP 3.0 was available for the third…

This report investigates three mini cases as provided by the brief (insert book title), these include Big E. Bank, Global consultants and Atlas advertising. The first mini case Big E. Banking (BEB) discusses the problems with connecting networks together over a wide area, all using different protocols to communicate. The second mini case addresses the problems with software acquisition including the methods used to communicate across different software products. The third mini case investigates…

Alongside CRISPR-Cas9 in site specific genome editing are ZFNs and TALENs. ZFNs are a DNA-binding motif assembled as ββα that utilizes a roughly thirty amino acid protein with DNA recognizing amino acids at the alpha helix (Gaj, Gersbach, & Barbas, 2013). These groups of amino acids usually recognize DNA in segments of three. This does not present much specificity in a genome. Therefore multiple DNA-binding motifs need to be combined to create specificity and result in highly specific…

1.1 Describe common physical network topologies Topologies Topologies describes the how different computers or other devices in a computer network is arranged. Topologies can be either physical (meaning placement of the components are arranged in a particular shape) or logical (meaning how data flows despite of its physical layout). There are different recognised topologies including star, mesh, tree and ring. In a star topology, each network device (computer or peripheral) is linked to a…

Mobile phone data transmission has several different ways of getting data from one point to the next. There have been several different standards developed over the years, which has changed the way we communicate. In this paper I will go over the history of mobile transmission, the different cellular access technologies, mobile broadband technologies, the top mobile phone companies, and the future of mobile phone transmission. My goal for this paper is to get a better understanding of how mobile…

(D. Tse and P. Viswanath, 2005) In 151, the proposed scheme is known as "the diversity of user cooperation," the author of this particular plan to achieve the rate in the region and the probability of failure. Sendonaris, who proposed a simple method of user cooperation, based on a signal of DF with the CDMA scheme. According to Liu (2009), different users with different orthogonal spreading codes can distinguish between different forms of cooperation from users to send information to the…

While ubiquitous Internet access is extremely convenient and enables marvelous new applications for mobile users, it also creates a major security vulnerability—by placing a passive receiver in the vicinity of the wireless transmitter, that receiver can obtain a copy of every packet that is transmitted! These packets can contain all kinds of sensitive information, including passwords, social security numbers, trade secrets, and private personal messages. A passive receiver that records a copy of…
