Communication Security (ComSec)

INTRODUCTION
Communication security is an important section of modern telecommunication systems where signal intelligences and other methods are used to provide secure communication among peers to be connected. Signal intelligence falls into the category of cryptography where the encrypted signal is collected and analyzed for propagating secure communication. This research work will explain the requirements of communication security and will discuss how signal intelligence can be used in communication security. These solutions can be used practically in communication security of the military services.
Signal intelligence is introduced and evolved by military services where signals from foreign communication systems are Continue reading...

Positive Bold fMRI Response in Neuroimaging

Positive Bold fMRI Response in Neuroimaging and its Relation to Neural Activity
Introduction
Some research suggests that functional magnetic resonance imaging (fMRI) signals result from an indirect measure of neural activity. Interpreting these signals allows making deductions about the nervous system and requires some understanding of the signaling mechanisms according to Logothetis and Wandell (2004). The following academic discourse explores, reviews, and describes the literature aligned with the focus of this subject identifying research variable outcomes.

About Positive Bold fMRI Response

As a part of cognitive neuroscience, the fMRI proves a revolutionized aspect in the last decade. The process is a coupling of the Continue reading...

Frequency and Amplitude Modulation has been in used for communication lines for many years (Poole, n.d.). During the early stages of wireless communication, frequency modulation (FM) cannot function under circumstances employing narrower bandwidth thus amplitude modulation (AM) is more predominant. Throughout the years of usage of FM and AM, the advantages and disadvantages between these two modulation types have been observed and have been used as basis for appropriate application.
The use of amplitude modulation over frequency modulation has its advantages and drawbacks. AM can be implemented easier, thus it is simpler compared to FM. It can be demodulated Continue reading...

Introduction:

Kanban is a technique used to determine production quantities in the work process thus facilitating Just-In-Time (JIT) production and ordering systems in lean manufacturing. Kanban was originally developed in the 1950s by the Toyota Motor Company - Japan to help manage the flow of materials in the assembly line. The main aim at the time was to secure active operator involvement and participation in order to improve system productivity through the provision of a highly visible means to observe product flow through the production system and inventory buildup within the system. Later, the method was further improved to help Continue reading...

Introduction
It is a part of the job of an energy manager that he minimizes the energy loss of the building by controlling the ambient temperature of the building or different parts of the building. In order to maintain the temperature and save valuable energy, a data acquisition and monitoring system is needed that will display the ambient temperature with the help of sensors. This supervisory control system will be designed to control the remote infrastructure that handles the heating system. The energy manager will be in control of this system. First the data of the room will be Continue reading...

Analog and digital signals, basically, differ in their graphs of voltage versus time. Analog signals have a continuous signal function with respect to time (Angoletta, 2014). The signal here can be sound, light, temperature, pressure, etc. The signals have smooth continuous changes similar to an analog watch. On the other hand, digital signals have a discrete (taking only binary values 0 and 1) function with respect to time. The signals have determined levels such as the case of the digital clock where time can only take account of 0 to 9.
The advantages of using analog versus digital signals Continue reading...
