Abstract: The demand for energy in continues to grow. This projected growth in demand has spurned several initiatives aimed at forestalling potential shortages. The focus is on influencing the energy consumption patterns in industry especially during peak demand times when energy supply systems are strained. Moreover, the modern society has become more sensitive to the impact on the environment. More consumers are aware today of the need to conserve energy. A typical platform will enable industry to reduce electricity usage. The ability to manage energy usage more effectively saves businesses. To ensure the provision of adequate, secure and cost-effective energy supplies, resources using the latest cost options are being utilized. To promote the efficient utilization of energy and discourage wasteful and non-productive patterns of energy consumption, the energy policy's approach is to rely heavily on industry to exercise efficiency in energy conversion, utilization and consumption through the implementation of awareness programs. This research will encourage engineers in industry to evaluate, investigate, discover and discuss the various opportunities available to manage energy in industry utilizing a well-structured and engineered methodology and to consider energy management initiatives seriously.

Abstract: In wireless sensor network (WSN), LEACH protocol is a typical representative of the hierarchical topology control protocol. Compared to plane multiple hops routing protocol, it can significantly prolong the life cycle of the network. But LEACH protocol having the problem of uneven distribution at the cluster head election, this paper proposes a low energy adaptive clustering routing protocol based on the partition. On the basis of the partition, cluster heads are selected by the energy of nodes and their location information. Simulation experiments show that the proposed protocol can be more effective than LEACH to balance the energy and improve the life cycle of the network.

Abstract: Product design, energy consumption and carbon emission belong to different domain. For the purpose of achieving low carbon and energy conservation design, the relation between design information and energy information must be established. This paper employs bond graph theory for extracting and expressing basic energy characteristics and presents a mapping framework between design information and energy information.

Abstract: The mobile grids bring some additional features into the grid, such as mobility, energy-constrained, etc. And the task scheduling becomes a more challenge thing. We propose a mobile grid task scheduling model considering the mobility of both user and resource, and the resource energy consumption. Through analyzing the architecture of mobile grid, a mathematical model is built to calculate the average distance between the resource and Base Station (BS). Then, it can decide which mobile grid the mobile devices are apt to stay in, which can deal with the mobility of mobile devices. On the other hand, the resource energy consumption is also considered, which ensure that the resources have enough energy to finish the task. As a result, the task can be assigned to the best resources in the suitable mobile grids. The failures may happen in the task scheduling because of many unpredictable factors. So the fault-tolerance scheme based on the notion of replication is proposed.

Abstract: Routing problem is one of the most important issues to a wireless sensor network (WSN). It is the key problem to find an efficient energy strategy for prolonging network's lifetime because power supply might be impossible. This paper discusses the multicast routing problem of WSN with multiple QoS constraints, which may deal with the delay, bandwidth, hop count and packet reception rat and surplus energy metrics, and finds a minimum resource consumption path while satisfying multiple constraints optimization conditions, and describes a network model for researching the multicast routing problem. It presents a dynamic multicast routing algorithm with multiple QoS constraints (MCQoSRA). The MCQoSRA successfully solves the QoS routing problems when multicast nodes change dynamically in the networks. The MCQoSRA only requires the local state information of the link (or node), but does not require any global network sate to be maintained. In MCQoSRA, a multicast group member can join or leave the multicast session dynamically. The MCQoSRA can effectively decrease the overhead for constructing a multicast tree and the delay of the nodes, and improve the success ratio of seeking links. Simulation results show that the MCQoSRA provides an available means to implement multicast routing, and adapt to all kinds of the topology networks, and have better expansibility.

Abstract: In wireless sensor network, node’s energy is limited. The energy consumption of transmission a bit is larger than that of handle a bit. If it adopt effective routing algorithm, it can greatly improve the energy efficiency of wireless sensor network. In order to improve the energy efficiency of wireless sensor network in the large area, we propose a clustering routing algorithm based on energy, the algorithm realize the multi-hops communication between cluster heads by dividing the WSN area into concentric rings, and reduce the size of radius of the clusters gradually when the nodes’ energy is decreasing slowly. The results of simulation show that the algorithm can effectively prolong the network lifetime.

Abstract: The energy of the node in Wireless Sensor Network (WSN) is supplied by the battery, and the energy is limited. In this paper, the more energy-efficient WSN routing protocol is improved, to support the operation of the WSN to prolong the lifetime of network as much as possible. On the basis of the existing Low Energy Adaptive Clustering Hierarchy (LEACH) routing protocol, a new Geography and Energy Cluster Algorithm is proposed. The new algorithm not only improve the biggest connectivity of the clustering routing protocol, but also balance the energy consumption of the whole network, and achieve more energy-efficient . The results of the simulation of the software indicated that the new improvement of GECA protocol is more efficient and prolongs the WSN lifetime.

Abstract: All of the performances of the car, break performance is one of the most important. In the stage of automotive design, road tests usually are not available, only special brake tests are used to simulate the test. Using brake tester is a good measure to decide the vehicle braking performance. To carry out the brakes test and to explore inertia, it can better simulate the actual use of the brake mode and environmental conditions, a more realistic response to brake performance, not only brake to improve the level of R & D to enhance the braking technology, but also can improve brake testing technology to improve the design level test bench, the most critical is a good control analysis of the mathematical modeling of the brake product development, quality control, and vehicle braking performance are very important. Based on the data calculation and analysis, model, and the control algorithm, obtained reasonable control of the brake test bench mathematical modeling, and the method to do the appropriate improvements.
