Abstract :


Electrical bioimpedance monitoring is an emerging tool for biomedical research. It constitutes one of the diagnostic methods, based on the study of the passive electrical properties of the biological tissues. Whole body bioelectrical impedance analysis (BIA) is widely used by researchers and clinicians as a non-invasive and safe method to estimate body composition and body water volume in children and adults. This paper is a brief study about the various bio impedance applications for determining multi physiological parameters i.e. arterial blood pressure, heart rate variability, cardiac output, breathing pattern, joint movement and blood glucose recognition. Bioimpedance is an effective parameter and is being researched widely. Since BIA is objective, safe, rapid and non-invasive method, it has been used for clinical diagnosis.

Abstract :


Live stream is a live streaming video platform that allows users to view and broadcast video content using a camera and a computer through the internet. This paper proposes the Public-Shared Network system that is capable of streaming content to numerous clients simultaneously and requires only a small amount of bandwidth is spent on the video streaming source. To optimize public-shared bandwidth and reduce the system load, the two algorithms were used and a resource management scheme was developed for recycling and reusing resources, without disturbing continuity of streaming. Also three innovative methods are used that users can use to optimize bandwidth management in video surveillance application such as multicasting, multistreaming and video compressions. The main intention of this paper is to construct efficient, reliable, and high-availability video streaming delivery system.

Abstract :


In this paper an Improved Differential Evolution (IDE) algorithm is proposed to solve optimal reactive power dispatch problem. Differential Evolution (DE) algorithm is a renowned population based stochastic algorithm used to solve optimization problems. But, DE, like other nature inspired algorithms, occasionally stuck in local optima and also undergoes from the problem of stagnation. To resolve these issues and improving the convergence speed of DE algorithm, Artificial Bee Colony algorithm?s fitness based position update strategy is assimilated with it. In the proposed algorithm, first all the solutions are updated their positions using the DE algorithm than the ABC search strategy is applied to improve the convergence speed of the exploration process. The proposed IDE algorithm has been tested on standard IEEE 57 bus test system and simulation results show clearly the better performance of the proposed algorithm in reducing the real power loss.

Abstract :


Water is a basic need. The provision of safe and adequate drinking water for rural and urban communities continues to be one of the major unfinished tasks. Lack of access to safe water seriously undermines the health and well being of the people. The poor and economically weaker sections are affected the most. Majority of the Indian Population lives in rural areas. At present also the rural community does not have access to safe, regular and adequate drinking water. Under the Swajaldhara scheme of Government of India (Swajaldhara guild line) to provide safe, regular, adequate drinking water to each and every village of this country. Loop 4.0 is used for simulation, design & optimization of looped water distribution network. Sensitivity Analysis is carried out for considering input parameter as pipe material, Population, Residential Pressure and observed the effect on output parameter as unit head loss, pipe diameter, and pressure respectively. The sensitivity analysis suggests that 10, 30 no. of pipes in zone-1 and 1,2,11 in zone-2 are more sensitive in HDPE network while 16,18,28 in zone-1 and 4,6,16 in zone-2 no. of pipes are more sensitive in case GI network. Moreover, HDPE network seems to be more sensitive compare to GI network. The sensitivity analysis for 1257, 1839 & 2207 population has been carried out. It has been found that the diameter of pipe increases with the increase in the population. Effect of change in input pressure on output pressure also been studied in the present work. Also Highly sensitive pipes need more attention in term of maintenance or replacement. It must be noted that the present study helps in identifying a set of pipes on a qualitative basis: however this will not help in quantifying magnitude of damage to pipes i.e. leaks, pipe breakages, pipe bursts etc. But still, the primary information obtained from the study helps in deciding a broad operation policy with respect to reparability or maintenance of the pipe network system.

Abstract :


Improving efficiency with extremely little exhaust in a robust and cost efficient manner with higher life of components are of prime important factors that a contemporary industrial gas turbine have to compete with. Rough surfaces are widely used to increase convective heat transfer by supporting the advancement in turbulence levels. The most common technique employed for enhancement of heat transfer rate in an internal cooling passage of a gas turbine blade is using ribs at regular intervals because of their simple fabrication, operation and low maintenance. Ribs have got major applications in various chemical process plants, refrigeration, nuclear, heat exchangers and gas turbines. In this research work, a computational study has been carried out to investigate the heat transfer characteristics in rectangular duct roughened by trapezoidal shaped rib (increasing height in flow direction) using CFD (ANSYS/FLUENT). The main objectives of this work are mainly (1) to study the effect of variation in trapezoidal angle (a = 0 to 22.5) on the heat transfer characteristics and (2) to study the effect of Reynolds number (Re = 10000 to 20000) on heat transfer characteristics for different Trapezoidal angles. It has been observed that the wall with different taper angles shaped ribs have high average heat transfer coefficient as compared to corresponding square shape rib. So, this investigation suitably offers an improved rib design for internal fluid flow investigations related to cooling applications. The results clearly enlightened that the highest of Nusselt number is corresponding to the taper angles of 22.5 in upstream side and 7.5 in downstream side of the rib.

Abstract :


In this paper we consider new cooperative communication system which consists of single antenna source, relay and destination. Modified Cooperative system utilizes the concept of spatial diversity and temporal diversity in order to achieve high diversity gain and better performance as compare to classical cooperative system without increasing number of antennas at source or destination node. Source node transmits symbols to destination with the help of relay which uses Amplify- and-Forward protocol and quadrature phase shift keying (QPSK). Main drawback of classical cooperative communication system using Amplify-and-Forward protocol is noise amplification which can be overcome by Modified Cooperative communication system. Mathematically, it has been analyzed improvement of diversity gain in the case of modified cooperative communication system. Finally, simulation validates the mathematical analysis.

Abstract :


Digital video is present in many applications, including video conferencing, DVDs, and broadcast television. Since digital video requires a prohibitive amount of storage in uncompressed form. There is a limit to the available storage space and hardware resources. The widely established compression standards suffer from the annoying blocking artifacts. The reason for the blocking artifacts is the usages of block based DCT. Therefore it is judicious to use discrete wavelet transform which can be directly applied to the whole image/frame at once. Therefore, this research develops an enhanced MPEG-2 video compression algorithm that explores the advantages of DWT. The compressibility factor, quality of reconstruction of frames; everything depends on the efficiency of the motion estimation algorithm that is used in the standard, therefore hybrid motion estimation technique (H-MET) based on Diamond Search (DS) algorithm and Adaptive Rood Pattern Search (ARPS) algorithm proposed. To measure the visual quality of the video parameters like: Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE), Structural Similarity Index (SSIM), Mean Absolute Difference (MAD), Blocking Beta, Blurring Beta etc. are used. Experimental results show that the MPEG codec with hybrid transformation and hybrid motion estimation technique (H-MET) provides more compression as well as less computational time as compared to existing MPEG codec.

Abstract :


Efficient consumption of energy and reduction in energy wastage is now widely seen as essential for business, as well as environment. However, small and medium scale organizations typically do not have facility of monitoring energy consumption and hence do not have necessary information to make proactive decisions about their energy usage. In such cases remote energy monitoring can prove to be an effective solution that can make a visible impact on the bottom line. Basically remote monitoring of energy meters includes fetching of data like voltage, current, power, power factor etc. from energy meters and send that data to controller or server. In this paper remote energy monitoring scheme that links energy meters over a campus to central monitoring server is proposed. The link between server and meters is based on MODBUS RTU protocol over TCP/IP via Ethernet. Through use of internet technology the system facilitates real time energy monitoring from any place over the internet along with desired analysis and reports. Further facility of notification of alarm conditions through SMS is also provided using GSM technology.
