IT133 – Week 3 Assignment

IT133 – Week 3 Assignment 4B/5B is a block encoding system that breaks up long strings of zeroes and ones but does not increase the frequency bandwidth by breaking them up in four-bit sequence. Table 1 shows each block of four bits replaced by a block of five bits. Due to this, there cannot be more than one leading zero and two trailing zeros. This means that the resulting bit stream has no more than three consecutive zeros (Figure 1). This bit stream is transmitted using non-return to zero inverted (NRZI) method and is used in 100BaseTX (Fast Ethernet) networks ...

Embodied cognition incorporates that the human cognition is comprised and shaped by various aspects of the body, which eventually indicates that it exceeds from the dependency on brain. In this manner, cognition is observed to be dependent on the experiences that an individual receives from numerous sensorimotor capabilities of the body. These capabilities are considered to be highly integrated in accordance with the psychological, biological and cultural setting of an individual (Wilson & Foglia 2011). Embodied cognition also accounts for the feedback mechanism that takes place between an individual and the world and hence, the prevalence of action ...

Transcriptional regulation of gene expression

Gene expression in eukaryotic cells is regulated at transcriptional, post transcriptional and translational levels (Tomizawa,  Lekstrom-Himes, and Xanthopoulos 17). Transcriptional control is the primary means of regulating gene expression. Eukaryotic transcriptional control functions at three levels: modulation of the activities of activators and repressors; variations in chromatin structure; and effect of activators and repressors on assembly of initiation complexes (Lodish et al. 368). Regulation of transcription initiation is the most widespread form of gene control in eukaryotes. However, in some cases, transcription may be attenuated and regulated at subsequent steps, such as during or after the transcription process (Cooper ...

Description

The Rett syndrome is originally known as cerebroatrophic hyperammonemia. It is a rare genetic disorder which commonly affects women although there are cases where it could be found in male patients. It is considered as a postnatal neurological disorder which affects the grey matter of the brain. Rett syndrome is also considered as a progressive disorder which affects the development of the brain. It is also considered as one of the common cause of mental disorders among women. It occur about 1 in 10,000 births and it typically develops at age 6 to 18 months. The signs or ...

Introduction

In recent decades, trends in diets tailored to promote weight loss have resulted in a significant increase in the intake of protein, particular in people with overweight and obesity issues. Accordingly, researchers have questioned the benefits or risks linked to the habitual consumption of “dietary protein in excess of recommended intakes” (Martin et al., 2005). In general, the primary concern has involved the possibility that diets rich in protein may increase hyperfiltration and, hence, exacerbate renal damage. Nevertheless, the potential link between protein-rich diets and renal damage has also been questioned due to an absence of adequate clinical evidence. ...

Cross-cultural Communication In the book's Preface, Tannen states: "all communication is more or less cross-cultural." (Tannen) What does she mean by this statement? This point has to be made because challenges arise in communication when there is more than one culture involved. In the communication process, culture differences are an issue during encoding and decoding. The challenge for the sender is to develop a message in forms that can be decoded successfully by the receiver without losing or misunderstanding the content and meaning of the message. The forms of communication like language and non-verbal communication are ...

Two of the more frustrating aspects of living in a modern, information society and the constant need to “have internet access” everywhere, all the time are finding a strong, and stable signal to provide access and the power drain to your device that results from the constant searching for and connecting to an accessible signal. One emerging technology that is working hard to resolve these two issues is known as passive Wi-Fi, or as it is more informally known, “backscattering” (Harris, 2016). Passive Wi-Fi refers to a technology that is being developed at the University of Washington that is ...

Communication System

The key elements of a data communication system are the source, the transmitter, the transmission system, the receiver and the destination. The source will be used in the generation of the data to be transmitted. The transmitter has a purpose of transforming and encoding the data into signals that can be transmittable for example the transformation from a digital bit stream to the corresponding analogue signal. The transmission system serves the purpose of carrying the data and it can be in terms of a transmission line or a complex network connecting the source and the destination. The receiver will ...

In the article, "Why Game of Thrones is taking over the world," writer Charlotte Runcie considers the popularity of the HBO television series noting that it is one of most popular shows of all time and is broadcast in roughly 170 countries.

The appeal is intricate and intense among fans. The show is recognized as exploring the topic of power, weaving in the comic and harsh realities of what is means ...

Communication is the process of exchanging information. When evaluating communication, it is important to consider the words used, body language, accent, and the subject. However, it is imperative to note that communication does not necessarily involve spoken words; silence or other nonverbal expressions such as smiling or frowning qualify as communication. Communication may only be labelled as effective when the recipient of the information comprehends the sense of the message and can relay it back to the sender. In other words, the receiver needs to understand the meaning and respond accordingly. On the contrary, if the recipient does not ...

Description of how MRI sequences spatially encode nuclei in the read and phase direction

Differences that occur in an induced magnetization in biological tissues in a magnetic field cause image contrast in MRI. A signal measured by the receiver coils is the integral of an induced magnetization over the whole imaged volume. To construct a three-dimensional distribution of magnetization, a spatially varying field pattern is generated in the volume, such that voxels at various parts generate a signal that is tagged with data on the location. Standard techniques for spatial encoding in MRI create high-quality images. In magnetic resonance imaging technique, two main methods (SVD MRI and SMASH MRI) are used to modify ...

Assignment about MRI Physics

The magnetic moment is considered as a vector quantity whose direction is perpendicular to the current loop in a right-hand-rule direction. The magnetic moment of nuclei are the magnetic moment of the nucleus that arises from a spin of protons and neutrons. A magnetic moment of nuclei is dipole moment – the quadrupole moment causes a shift in the hyperfine structure (Mangrum, 2012). Nuclei with non-zero spin have a non-zero magnetic moment while that have zero spins have zero magnetic moments. Different isotopes of an element have a different nuclei magnetic moment. A nucleus with an even number of protons ...

Basic communication literatures would differentiate various methodologies that highlight how significant encoding and decoding are in the process of communication in general. By the literal translation, the process of encoding signifies the conversion of various pieces of information from system into another with the use codes. These codes can fall different categories such as sign, letters or symbols that be generated to form secret meaning. The process of coding constitutes to both rules and signs that decipher how the signs are used and what complex messages are formed. Both culture and sub culture are formed due to the full-pledged ...
