In wireless sensor network nodes position estimation in space is known as localization. Node localization in wireless sensor network is important for many applications and to find the position with Received Signal Strength Indicator requires a number of anchor nodes. However the estimation of distance from signal strength decay in not very accurate especially in time varying environmental conditions and the estimation of exact direction required highly directive antenna but, may still affected by multipath fading. A Genetic Algorithm for wireless sensor network localization is proposed in this paper to solve the issue that the positioning accuracy is low with minimum anchor nodes. Hence in this paper we are presenting a Genetic algorithm for optimization approach which tries to find the optimal location by satisfying both the criteria with minimal error. The simulation results also shows effectively outperform both the techniques.
Vehicle Sensor Networks (VSN) are emerging as a new tool for effectively monitoring the physical world, especially in urban areas where a high concentration of vehicles equipped with on board sensors is expected.A vehicle tracking system combines the installation of an electronic device in a vehicle, or fleet of vehicles, with purpose-designed computer software at least at one operational base to enable the owner or a third party to track the vehicle’s location, collecting data in the process from the field and deliver it to the base of operation.
The heart of this paper here is a LPG gas leakage sensor circuit that detects the outflow of LPG gas and the circuit is a gas sensor module SEN 1327. QM 6 gas sensor is used in the SEN 1327 module.
The gas analyzer market units are estimated to be 639 thousand units in 2013, growing at a CAGR of 4.3% between 2013 and 2018. In terms of revenue, the gas sensor, and detectors markets are expected to grow at a CAGR of 6.1% and 5.7% respectively, during the same period.

An easy-to-use entry level digital SLR camera, offering high-quality performance and outstanding value for money PENTAX RICOH IMAGING COMPANY, LTD. is pleased to announce the launch of the PENTAX K-500 digital SLR camera. With its solid basic specifications and outstanding value for price, this new model is designed to extend the joy of high-quality digital SLR photography to everyone. The PENTAX K-500 was developed based on the PENTAX K-50 digital SLR camera (launched in June 2013). This cost-efficient model inherits such remarkable features as a compact, lightweight, easy-to-hold body; high-resolution image reproduction with approximately 16.2 effective megapixels; super-high-sensitivity shooting at ISO 51200; and high-speed continuous shooting at approximately six images per second, making it an ideal imaging tool for all casual digital photographers. Major Features 1. High-resolution, super-high-sensitivity shooting at ISO 51200 The K-500 features the state-of-the-art CMOS image sensor with a large image-capturing area measuring 23.7mm by 15.7mm, to assure high-speed image data readout. This image sensor is coupled with PRIME M — the same high-performance imaging engine incorporated in upper-class models — to deliver super-high-resolution, rich-gradation digital images with approximately 16.28 effective megapixels. The K-500 also offers super-high-sensitivity shooting at a top sensitivity of ISO 51200, allowing the photographer to handhold the camera for beautiful nighttime snapshots.
The street presence is pure Ram 1500. But this engineering goes way beyond muscle and capability. Here, performance is so good, quality is measured in terms of decades.What you see is a dramatic forward-raking grille and sleek exterior — but the story is bigger: This design contributes to reducing air friction and drag. The results? Best-in-class aerodynamics. An honor, to be sure, but one that helps improve fuel consumption, further reduces wind noise, and even helps channel rain and water away from the windshield much more eff ectively.An integral part of the tailgate design, the spoiler also functions to direct airﬂow away from the body — with measurable improvements that help reduce aero drag.Door seals for Ram 1500 off er a triple-play of advantages: They help lock out road noise, create an airtight seal, and boost the interior comfort level.Ram 1500 Laramie Crew Cab shown in two-tone Inferno Red Crystal Pearl and Light Graystone Pearl.
