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.

Bike that Runs on Compressed Air (let’s move from  black oil past to a green air future…)

In the present energy scenario the rate of depletion of fossil fuel sources is increasing day after day and their combustion products are causing global environmental problems. So it is inevitable to shift towards the use of renewable energy resources which in turn will reduce pollution and save fossil fuels. AIR POWERED ENGINE is an alternative technology which uses compressed air to run the engine and thus eliminates the use of fossil fuels. Exhaust coming out would be air only and thus would help in controlling global warming and reducing temperature rise

Effect of some factors on lipase production by Bacillus  cereus isolated from diesel fuel polluted s

Optimization the production of extracellular lipase in culture of Bacillus cereus has been investigated. From 10 samples of diesel fuel polluted soil it was found that 3 samples was positive for the presence of B. cereus. Lipase production by B. cereus isolated from diesel fuel polluted soil was investigated and optimized. The enzyme production was increased with increasing time and maximum enzyme activity was obtained after 72 hrs of incubation. Effect of pH and temperature indicated that, the lipase production was maximum at pH 8.0 (60.2 U/ml) and at 35°C (55.25 U/ml). The lipase production was optimized in shake flask experiments. With a selected carbon sources, maltose (65.5 U/mL) and nitrogen source, peptone (66.25 U/mL) was suitable substrates for accelerating lipase production. The present study indicates that the various factors influenced enzyme production by the bacteria, it appears that the nature of the supplements had significantly influenced on the produc

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.

Pollution Studies in the Chengannur Segment of River  Pampa Based on Physical Parameters.

Pampa River is the third longest river in the South Indian state of Kerala. The river is one of the most stressed rivers in Kerala .Water quality of Chengannur segment of Pampa River was determined based on Physical parameters such as TDS,Turbidity,Temperature and Conductivity followed by water quality index. Three study sites were selected. Mean with standard deviation were taken. Two way ANOVA was conducted. The water quality index (WqI) was calculated. The quality index was84 forTDS and 98 forTurbidity during premonsoon and summer . The study shows that water in the Chengannur segment of Pampa river is of moderate quality

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.

Primary Production estimation in the euphotic zone of a  Tropical Harbour Ecosystem, Nigeria

Primary productivity and selected relevant associated physico-chemical parameters in the euphotic zone of Lagos Harbour, a tropical Harbour was monitored at NIOMR Jetty station (Latitude 6º 25 ´ 14, 88º N, Longitude 3º 24´ 24, 42º E) on a monthly basis from October, 2012 to March, 2013. Air and surface water temperature ranged from 23.5⁰C to 28⁰C and between 27 ⁰C and 30⁰C respectively. Alkaline pH ranged (7.81 to 8.45). Brackish salinity varied from 6.2 to 35.4PSU while Electrical conductivity minimum and maximum values were 11200 and 53300µS/cm respectively. Moderate dissolved oxygen ranged between 5.0mg/l and 6.4mg/l, slightly lower than 6.8mg/l standard suggested by FEPA. Total dissolved solid ranged from 7504 to 35711mg/l while Low Alkalinity varied between 12 and 20mg/l. Rainfall minimum and maximum values were 8.8 and 229mm respectively. Gross primary production (GPP) varied from 0.22 to 0.46gC/m 2 /day. The corresponding Net primary production (NPP)

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

Oguchi Approximation of a mixed spin-2 and spin-5/2  Blume-Capel Ising ferrimagnetic system

By using the Oguchi approximation(OA), we study a mixed spin-2 and spin-5/2 Blume-Capel Ising ferrimagnet with different single-ion anisotropies on a simple cubic lattice. It has been carried out Oguchi method and calculated the free energy of a mixed spin ferrimagnetic model from the partition function. By minimizing the free energy, it has been obtained the equilibrium magnetizations and the compensation temperatures. The existence and dependence of a compensation temperature on the crystal field is mainly investigated.
