http://www.madgetech.com/advancedsearch/result/?q=RHTemp101A&x=0&y=0 | Warehouse mapping is an important procedure for analyzing temperature variations in a facility that stores perishable materials like foods and pharmaceuticals. Using quality data loggers is essential for ensuring the success of this procedure.
Facebook and Ericsson, working together as part of the internet.org initiative championed by Facebook CEO Mark Zuckerberg to boost online connectivity in emerging markets, claimed they can improve app performance by up to 70 per cent. The companies said they have developed a methodology to measure and optimise network performance that can be applied globally. A joint project created a framework for evaluating user key performance indicators based on simulated Facebook app use cases using a test agent and correlating those with network statistics. By identifying and addressing user-impacting issues, they said they were able to increase the number of connections completed within three seconds by 70 per cent, reduce the time to content by up to 70 per cent and cut upload time up to 50 per cent.
Direct dock style wafer probing allows for a higher bandwidth, increased pin density and testing more devices in parallel. Direct dock probe cards also support the growing movement of traditional final test to wafer probe which allows for known good die (KGD) and reduced cost of ownership.
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.
- This paper presents the concept of using a polyethene film to address the shortcomings of the conventional solar pond which are low efficiency, short operation time among others. The thermal behavior of a solar pond with a polyethene has been analyzed and compared with that without a polyethene film. The experiments show that: the heat storage layer (LCZ) temperature rising rate was significantly higher than that of single layer porous media solar pond. The polyethene film of thickness 100µm was used. The polyethene film brings about the greenhouse effect where the solar energy that penetrates the film is trapped and improves the efficiency of the storage zone. Results show that the efficiency of a polyethene stabilized pond rises to about 69 % compared to the conventional solar pond with about 52 %.
The functioning of calcium lignosulfonate (CLS) as the potential inhibitor in the corrosion of mild steel in 0.5 M H2SO4 medium has been studied. The various parameters in connection with the corrosion behaviour of the metal and the inhibitive action of CLS were obtained by weight loss, potentiodynamic polarisation, electrochemical impedance spectroscopy (EIS) and scanning electron microscopy(SEM) methods. The effect of temperature on the mild steel surface has been reported. The results of the present investigation show that CLS acts as a good inhibitor and it is of mixed type. The mode of action is by the process of adsorption at anodic and cathodic sites. The scanning electron microscopic studies gives the picture of surface morpholog
