Mobile communications have evolved in a very rapid manner along with other fast-growing communication technologies. The widespread use of this technology has turned mobile communications into a life style. Thus the necessity for high quality and high capacity networks with thorough coverage has become one of the major demands. Many models have been proposed to cover the signal strength measurements...
The Measurement of radio wave propagation into and within buildings at 900 and 1800 MHz frequencies have been undertaken using the library building at the University of Bridgeport campus in CT, USA. Furthermore, the signal propagation for the cases into and within elevator has also been investigated. Signal loss is a major problem for cellular wireless devices, resulting in dropped calls and failure...
Mobile phone base station (tower) provides coverage for one or more geographical areas, known as cells. A mobile phone network is made up of a base station operating in conjunction with adjacent base stations. Base stations must be carefully located in relation to each other, so each cell in the network functions efficiently to ensure minimum interference between cells and good signal quality. One...
The Electrical interaction and the signaling process between a neuron and a metal oxide semiconductor field effect transistor (MOSFET) in a nanostructure circuit have led to a growing interest in computer brain interface. A wide variety of neuron silicon sensors and systems have been developed [2]. Typically, such brain chip interfaces rely on miniature sensors/electrodes that can get inside the interfaces...
This paper demonstrates the Least Mean Square (LMS) adaptive filter for adaptive noise (interference) removal. A measured signal contains an unknown signal of interest and an interference signal. The goal is to design an LMS based adaptive noise canceller that adaptively removes the maternal heartbeat signal from the fetal electrocardiogram signal. This Least Mean Square based adaptive filter will...
Big Data has shown lot of potential in real world industry and research community. We support the power and potential of it in solving real world problems. However, it is imperative to understand Big Data through the lens of 7 V's. 7th V as ‘Value’ is desired output for industry challenges and issues. We provide a brief survey study of 7 Vs of Big Data in order to understand Big Data and extract Value...
This paper describes the implementation of a Transport System database. We have used the entity-relationship model to design a database that will store and organize the details of the transport system. Using MySQL and an internet based graphical user interface, this database will allow everyone to access it remotely. The user will be able to view the route map from the given source to a destination...
Research into pronunciation and acoustic properties of foreign speech have evolved with technology and produced interesting results. The production of English vowel sounds by native Mandarin and Hindi speakers were investigated. The first three formant frequencies (F1, F2) and the mean and standard deviation values are calculated. The goal of this study is to contribute to a richer understanding of...
Head-Related Transfer Functions (HRTFs) are commonly used to impose a virtual location of origin to mono-aural digital sounds. In listening tests, however, subjects tend to confuse the virtual location of sounds from the front hemisphere with symmetric locations in the back hemisphere, and vice versa, in an effect called “Cone of Confusion”. Preliminary observations suggested that the HRTFs of individuals...
