And Performance

Wireless Sensor Network (WSN) applications that favor more local computations and less communication can contribute to solving the problem of high power consumption and performance issues plaguing most centralized WSN applications. In this study, we present a fully distributed solution, where leaks are detected in a water distribution network via only local collaborations between a sensor node and its close neighbors, without the need for long-distance transmissions via several hops to a centralized fusion center. A complete approach that includes the design, simulation, and physical measurements, showing how distributed computing implemented via a distributed Kalman filter improves the accuracy of leak detection and the power consumption is presented. The results from the physical implementation show that distributed data fusion increases the accuracy of leak detection while preserving WSN lifetime.

Partition Method

This paper aims to minimize power consumption and sustain customer satisfaction for a datacenter. In some distributed computing environments, especially in a cloud computing environment, the most concerned issue for a datacenter designer is power consumption instead of its speed. This is because the storage devices always consume much electricity. To save power, we can assign to each device proper workload and turn off some spare devices. Therefore, partitioning data and allocating them among the storage devices becomes the first priority. However, due to some complex constraints, the data partition problem is very time-consuming or even NP-hard. Therefore, we propose a gradient-based method to deal with the problem. The novelty of the proposed method lies in that the discretized combinatorial problem is solved by a calculus-based technique. Experimental results show that significant energy is saved by shutting down as many uncalled-for devices as possible. The results also suggest that other similar optimization problems can be solved by the linearly-convergent method.

Cloud Computing has been viewed as the cutting edge design of Information Technology. The Cloud worldview included points of interest and its potential for diminishing expenses and time for an administration that favors towards security issues. Distributed computing is an accumulation of data technology(IT) that offered to the client dependent on renting. In spite of the fact that countless security issues are tended to, in any case some are not tended to and a few calculations are proposed for security issues. This paper shows an on the Power Consumption of utilizing our refreshed H-HABE calculations and contrast and the different encryption systems. A similar report made on a few encryption systems are utilized for power utilization in the cloud. At long last, the significant measurements like Power Consumption issues present in distributed computing are examined

Computing Approach

Beamforming performance of autonomous, distributed sonar array degrades due to random position deviation. A new algorithm for beamforming based on Least Squares (LS) approximation of the desired beampattern is proposed in this paper. Elements of autonomous, distributed array are battery-powered and capable of computing with microprocessor. Centralized approach has shortcoming of failures due to excessive power consumption and lower fault-tolerant capability. Distributed computing approach of LS solution has profound significance with respect to longer life period and better robustness for autonomous sonar array systems.

Shim Coil

It is necessary to develop a high homogeneous, low power consumption, high frequency and small-size shim coil for high precision and low-cost atomic spin gyroscope (ASG). To provide the shim coil, a multi-objective optimization design method is proposed. All structural parameters including the wire diameter are optimized. In addition to the homogeneity, the size of optimized coil, especially the axial position and winding number, is restricted to develop the small-size shim coil with low power consumption. The 0-1 linear programming is adopted in the optimal model to conveniently describe winding distributions. The branch and bound algorithm is used to solve this model. Theoretical optimization results show that the homogeneity of the optimized shim coil is several orders of magnitudes better than the same-size solenoid. A simulation experiment is also conducted. Experimental results show that optimization results are verified, and power consumption of the optimized coil is about half of the solenoid when providing the same uniform magnetic field. This indicates that the proposed optimal method is feasible to develop shim coil for ASG.

Halogen Lamps

This work contains analysis of characteristics of automobile lamps by Philips, KOITO, ETI flip chip LEDs, Osram, General Electric (GE), Gtinthebox, OSLAMPledbulbs with H1, H4, H7, H11 caps: luminous flux, luminous efficacy, correlated colour temperature. Characteristics of the studied samples are analysed before the operation of the lamps. The analysis of the calculation results allows us to make a conclusion that the values of correlated colour temperature of halogen lamps are close to the parameters declared by manufacturers. The analysis of the study results has shown that, based on actual values of correlated colour temperature, it is not advisable to use LED lamps in unfavourable weather conditions (such as rain, fog, snow). The results of the study demonstrate that there is a slight dispersion of actual values of luminous flux of halogen lamps by different manufacturers. Maximum variation between values of luminous flux of different lamps does not exceed 14 %. The analysis of the measurement results has shown that actual values of luminous flux of all halogen lamps comply with the mandatory rules specified in the UN/ECE Regulation No. 37 and luminous flux of LED lamps exceeds maximum allowable value by more than 8 %. Luminous efficacy of LED lamps is higher than that of halogen lamps: more than 82 lm/W and lower power consumption. The results of the measurements have shown that power consumption of a LED automobile lamp is lower than that of similar halogen lamps by 3 times and their luminous efficacy is higher by 5 times.
