Pages: 1 - 9
Currently protection codes are essential to memory cells using to maintain a good reliability, various error detection and error correction methods can be used but to avoid corruption data Error correction code (ECC) are mostly widely used and introduced a delay penalty in accessing the encoding and decoding process can be performed but limitation of ECC are low speed performed in memory .it can be contributed to the utilization of simple code such as single error correction (SEC) and Double error correction (DEC) and detection. Matrix Codes (MC) constructed on hamming codes has been proposed for memory protection. The main dispute is that they are double error correction codes and the error correction capabilities are not enhanced in all cases. Decimal Matrix Code (DMC) structure on matrix and divide symbol is proposed to improve memory reliability with lesser delay. In this thesis, 64-bits and 128-bits Decimal Matrix Code is offered to assure the memory reliability. Here to detect and correct up to 9 and 17 errors respectively. The offered DMC based on decimal algorithm to extended the number of detection and correction capability of error bits stored in memory. More ever structure area of DMC is reduced by reusing its Encoder this is called Encoder Reuse Techniques (ERT). ERT can be used to minimize area without interrupting DMC encoder and decoder. ERT Uses DMC Encoder itself to be a part of decoder. Hence the entire structure area of DMC can be minimized. Using Xilinx Design Suite 14.2 simulation and implementation analysis can be done. Next A Verilog Description has been adopted to embed the low power design.

Year: 2015, Volume:2, Issue : 4
Pages: 28 - 35
This paper emphasis on the study of typical premature failure of water wall tubes of two thermal power plant boiler of same capacity (250 MW) and same operational parameter but with different boiler water chemistry. The investigation concludes on the waterside corrosion in both of the case. One boiler is running with coordinated phosphate treatment (CPT) and another with all volatile treatment (AVT). The causes of corrosion were discovered and proposed measures for their elimination were given. Visual examination, chemical analysis of deposits, oxide scale thickness measurement and micro structural examination were carried to ascertain the probable cause/causes of failure. From the investigation, it was finally concluded that the combination of localized high tube metal temperature and wall thinning due to under deposit corrosion led to the premature tube failure in boiler running with coordinated phosphate treatment and localized pitting corrosion in boiler running with AVT. Based on the results and discussions, a possible way to combat the corrosion was proposed.

Pages: 36 - 41
Cognitive Radio (CR) systems are the upcoming technology in the wireless communication where we have to utilize our spectrum available in the best and the efficient way. The tasks to be covered in the CR technology are broadly classified into two categories .They are efficient utilization of the available spectrum and secondly energy efficiency in the wireless transmission. As said above that in the wireless communication system we have major two challenges are to utilize the spectrum efficiently by also keeping in mind that the least power gets wasted during this process. In this work, we have presented different algorithms like that of Shared Carrier Assignment (SCA) Iterative water-filling algorithm (SCA-IWF) algorithm for efficient utilization of spectrum by sensing it keeping in concern the interference from the other secondary users. Secondly we have provided the energy efficiency of the MIMO system by using Iterative Power Allocation Scheme (IPAS) that converges as the number of iterations increased. Finally we have plotted the result of both the capacity and energy efficiency with respect to number of iterations in both the graph and bar-graph form.

Pages: 50 - 57
We are currently using smart phone sensors to detect physical activities. The sensors which are currently being used are accelerometer, gyroscope, barometer, etc. Recently, smart phones, equipped with a rich set of sensors, are explored as alternative platforms for human activity recognition. Automatic recognition of physical activities – commonly referred to as human activity recognition (HAR) – has emerged as a key research area in human-computer interaction (HCI) and mobile and ubiquitous computing. One goal of activity recognition is to provide information on a user’s behavior that allows computing systems to proactively assist users with their tasks. Human activity recognition requires running classification algorithms, originating from statistical machine learning techniques. Mostly, supervised or semi-supervised learning techniques are utilized and such techniques rely on labeled data, i.e., associated with a specific class or activity. In most of the cases, the user is required to label the activities and this, in turn, increases the burden on the user. Hence, user- independent training and activity recognition are required to foster the use of human activity recognition systems where the system can use the training data from other users in classifying the activities of a new subject.

Nursing home residents with dementia face challenges in adapting to a new living environment and feeling at home. Due to communicative limitations, people with dementia after often left out of design processes. The aim of this study is to investigate the housing needs in relation to the interior design on the object level and design level. Based on the principles of practice development, seven residents participated in a creative workshop in which they produced a mood board, followed by subsequent interviews. People with dementia value colours in the built environments, their own practical pieces of furniture, and personal belongings like pictures of relatives. Their sense of home turned out to depend more on the social environment than the built environment. We conclude that involving older people with dementia can lead to a better match between the needs and design solutions and can stimulate the dialogue between design stakeholders.

Pages: 72 - 80
As technology improve the size will be reduced, and the power dissipated by the links of a network-on-chip (NoC) is starts to participate with the power dissipate by the other element of communication system, for example the routers and the network interfaces (NIs). We design an set of data encoding technique by different schemes to decrease the power dissipation by an links of NoC, which optimizing the on-chip communication system not only in terms of performance but also in terms of power. The idea presented in this paper is base on encoding the packets before they are inserted in to the network in such a way as to minimize both the switching action and the coupling-switching action in the NoC’s link which represent the main factor of power dissipation. These schemes were universal and transparent with respect to the construct NoC fabric that means this application will not require any change in the router and link of architecture. These will be carried in both artificial and real traffic scenario. These effective of the proposed scheme will tolerate to save the energy consumption and power dissipation without changing the performance degradation and with less area consumption in the NI.
