Improving Wireless Sensor Network Performance Using  BigData and Clustering Approach

Well-organized big data get together in the densely distributed sensor networks is, therefore, a challenging research area. One of the most effective solutions to address this challenge is to utilize the sink node’s mobility to facilitate the data gathering. While this technique can reduce energy consumption of the sensor nodes, the use of mobile sink presents additional Challenges such as determining the sink node’s trajectory and cluster formation prior to data collection. In this paper, we propose a new mobile sink routing and data gathering method through network clustering based on modified ExpectationMaximization (EM) technique. In addition, we derive an optimal number of clusters to minimize the energy consumption. The effectiveness of our proposal is verified through numerical results.

Solar power for Wireless Sensor Networks in  Environment Monitoring Applications-A Review

Routing in Wireless Sensor Networks has to take into account the limited battery resources of the nodes. Sensor nodes can also be powered by other energy sources like solar energy. This paper provides a review of Environment monitoring using Wireless Sensor Networks. The issues related to environment sensor networks is highlighted. The real time applications in environment monitoring is presented with emphasis on energy conservation. Furthermore in this paper we address the problem of scavenging energy using solar powered devices.

Factors influencing Sexual Risk Behaviors among Senior  Secondary School Students (Youths)

This quantitative descriptive cross sectional study explored factors influencing sexual risk behaviours among youths in senior secondary schools in Ethiopia. Data were collected using structured questionnaires. Religious attachment, living with friends, living alone, parental control, level of parental education, peer pressure and number of friends who had experienced sex were some of the factors noted to influence youths to engage in sexual risk behaviours. The findings of this study have implications for both practice and policy development. They will enable healthcare workers to identify youths at risk of engaging in sexual risk behaviours and subsequently motivate them using health promotion strategies to engage in safe sexual practices. Adopting such an approach will prevent or at least minimise risk of youths being infected with sexually transmitted diseases, such as HIV/AIDS.

Measuring Occupational Stress among Management  Information Systems Workers and Users in the Financi

Occupational stress is considered to be a main health problem for both individuals and organizations. This study has investigated the measurement of occupational stress among Management Information Systems (MIS) Users in different banks in the Kingdom of Bahrain. Furthermore, to identify their high job stressor factors and increase understanding of the impact of individuals differences in occupational stress. A descriptive, cross sectional survey was performed in five banks. Using quota sampling, MIS users’ from different divisions were asked to complete questionnaires- including demographic data, job stress and stressor factors. Six main stress factors were identified among MIS users banker staff: 1) intrinsic work characteristics (job design); 2) work culture and function; 3) managerial role; 4) career development; 5) relationships at work and 6) home-work interface. A total of 250 self-administrated questionnaires were distributed (hand delivery) to the banks divisions. The overall response rate was 80.8% (202/250) and the result suggested that over a third of MIS users in banks reported that their jobs were highly stressful. The bankers are exposed to high job stressors such as job design (overload, long working hours, deadlines and time pressure, repetitive task and lack of variety, and shortages of staff); and career development (under promotion and working at a level below their level of abilities and skills). However, the result of this research can be applied for improving sources of occupational stress and further, precluding severe stress and concern was expressed that such findings should be considered when delivering stress management programs.

Review on Basic Clustering Techniques for  Heterogeneous Wireless Sensor Networks

Clustering technique is the basic technique used in the wireless sensor network to enhance the lifetime of a sensor network by mitigating energy consumption and provide efficiency, scalability, and security. Formerly sensor nodes are considered to be homogeneous in which each node has the same processing capacity, energy and functionality, but to prolong network lifetime researches has been evolved to infuse heterogeneity in wireless sensor network such as to provide different energy level to some nodes. In this paper, we present a survey on basic clustering techniques for Heterogeneous wireless sensor networks.

CFD Analysis of Pelton Runner
by ijsrporg 0 Comments favorite 6 Viewed Download 0 Times

This paper presents Computational Fluid Dynamics (CFD) analysis of Pelton turbine of Khimti Hydropower in Nepal. The purpose of CFD analysis is to determine torque generated by the turbine and pressure distributions in bucket for further work on fatigue analysis. The CFD analysis is carried out on model size Pelton runner reduced at 1:3.5 scale to minimize computational cost and time. The operating conditions for model size runner is selected in accordance with IEC 60193 and IEC 1116. The paper describes the methods used for CFD analysis using ANSYS CFX software. 3 buckets are used to predict the flow behavior of complete Pelton turbine. k-ε and SST turbulence model with interphase transfer method as free surface and mixture model is compared in the paper. The pressure distribution is found maximum at bucket tip and runner Pitch Circle Diameter (PCD). The torque generated by the middle bucket is replicated over time to determine total torque generated by Pelton turbine.

Murderer Algorithm Based Automatic Waking up  System

As the world runs fast, its our duty to run with the world compensating its speed. There is an urge to prove everyone unique. Hence time management play a worthless role in the daily work of a person. At morning it is a herculean task to wake up from the bed. “Let me sleep for some more time” is the first slogan of everyone every morning. But feeling guilty for not waking up in the morning is also encountered in several cases. In this paper we propose a novel “Murderer Algorithm” based automatic waking up system that helps to wake up every morning. The uniqueness of the system is to make the person in the bed to wakeup and get away from the bed. The device employs simple capacitive touch sensor to sense the presence of a person and also a brig

LONGEVITY Offers Advanced Welding Machine for Versatile Industrial Applications

The welding machine has really made the tough job of welding two different materials easy. Previously, welding two different metals was a Herculean task, and it used to take a lot of time and pressure, but with the modern invention of welding equipment, the task of welding has dramatically changed.
