Investigation on the Existing Geometry of Pathein Suspension Bridge

Pathein Suspension Bridge constructed across Pathein River completed in 2004 is a single-span suspension bridge. The region has soft alluvial ground. According to 2012 bridge inspection report, Current Situation and Issues of Myanmars Bridge Work, this suspension bridge had lost a great deal of camber since completion. And also it is found that there are some problems such as movement of anchor block, tilting tower. In this study, investigations on the existing of Pathein suspension bridge are presented by using 3D laser scanner, and site surveying. 

According to the investigation results, it is found that all towers are inclined towards river and the maximum inclination occurs the downstream tower of Chaungthar side. The downstream main cable sag is lower than the upstream one. Most hangers are inclined towards Pathein side and the maximum inclination degree occurs at middle portion. The existing truss profile is very different from as per drawing and all truss nodes are under the horizontal surface. Therefore seismic risk assessment and disaster mitigation plan for unexpected future severe earthquake should be developed.

Analysis of Adsorption Time for Solar Adsorption Refrigeration System

The solar adsorption Refrigeration system is very useful in rural area without grid. The Adsorber desorber are the important role in this system. Among the adsorbent - refrigerant, the activated carbon and ethanol is applied. This paper focuses on the adsorption time of adsorber bed with constant thickness.

Inter-Cell Interference

The continuously increasing demand for higher data rates results in increasing network density, so that inter-cell interference is becoming the most serious obstacle towards spectral efficiency. Considering that radio resources are limited and expensive, new techniques are required for the next generation of cellular networks, to enable a more efficient way to allocate and use radio resources. In this framework, we target the design of a frequency reuse 1 scheme, which exploits the coordination between base stations as a tool to mitigate inter-cell interference.

Spectrum Handoff Decisions

In modern society wireless communication plays a very important role with huge increase of users, services and standards. Although there are several pros of using cognitive radio networks, for example increasing the spectrum utilization of wireless networks, but still there exist some challenges which need to be discussed in detail First, since cognitive radio networks are planned to operate over a heterogeneous spectrum environment, which comprises of both licensed and unlicensed spectrum bands, most of the research has been done in only the licensed band of the spectrum and only some research has been carried out in such an environment as merging licensed and unlicensed spectrum bands for transmission increases the spectrum utilization of cognitive radio wireless networks. There is need to develop new spectrum handoff schemes to improve the performance of the secondary users in terms of their handoff delay.

Image Filtering Based on GMSK

Image Denoising is an important pre-processing task which is used before further processing of image. The purpose of denoising is to remove the noise while retaining the edges and other detailed features. This noise gets introduced during the process of acquisition, transmission and reception and storage and retrieval of the data. Due to this there is degradation in visual quality of image. The noises which are of major considerations are Additive White Gaussian Noise AWGN and Impulsive Noise.

Design and Simulation of Low Noise Amplifier at 15 GHz Using Advanced Design System ADS

the first stage of each microwave receiver there is low noise amplifier LNA circuit, and this state has important rule in quality factor of the receiver. In this study, design and simulation of 15 GHz low noise amplifier LNA have been explored. This simulation has been performed by using the Agilent Advanced Design System ADS software. It also describes the design and simulation of a high frequency low noise amplifier, with high gain and low noise using MESFET for frequency 15GHz.

A single stage LNA has successfully designed with 14.5 dB forward gain and 0.003dB noise figure in frequency of 15GHz.The NE76000 transistor was chosen for the design of the LNA due to its low noise figure, stability, and good gain at high frequency, good input and output impedance matching. Also the designed LNA should be working stably in frequency of 15GHz.
