The present paper aims to improve the dynamical balancing of a slider-crank mechanism. This mechanism has been widely used in internal combustion engines, especially vehicle engines; hence, its dynamical balancing is important significantly. To have a full balance mechanism, the shaking forces and shaking moment of foundations should be eliminated completely. However, this elimination is usuall...

Industrial Underwater Acoustic Sensor Networks (IUASNs) come with intrinsic challenges like long propagation delay, small bandwidth, large energy consumption, three-dimensional deployment, and high deployment and battery replacement cost. Any routing strategy proposed for IUASN must take into account these constraints. The vector based forwarding schemes in literature forward data packets to si...

ZigBee hierarchical tree routing protocol (HRP; ZigBee Alliance, San Ramon, CA, USA) provides a simple but reliable topology. However, the transmission routes are not always efficient, and the links are fixed after they were determined during the network initialization. In this paper, we propose an adaptive routing optimization and energy-balancing algorithm in ZigBee hierarchical networks. In ...

Cloud computing is a highly scalable and cost-effective infrastructure for running HPC, enterprise and Web applications. However rapid growth of the demand for computational power by scientific, business and webapplications has led to the creation of large-scale data centers consuming enormous amounts of electrical power. Hence, energy-efficient solutions are required to minimize their energy c...

Wireless Sensor Network (WSN) is a major and very interesting technology, which consists of small battery powered sensor nodes with limited power resources. The sensor nodes are inaccessible to the user once they are deployed. Replacing the battery is not possible every time. Hence in order to improve the lifetime of the network, energy efficiency of the network needs to be maximized by decreas...

Hydraulic balancing is key to ensure proper operation of the heating system. When system not hydraulically balanced, heat unevenly distributed across dwellings resulting in a wide temperature spread, overheating, and consequently, wastage energy. In this paper, we study which extent hydraulic imbalance affects thermal energy demand buildings. Furthermore, variables interactions that influence p...

This paper introduces an energy efficient clustering algorithm for sensor network based on the leach protocol. The proposed algorithm adds features to leach and aims to reduce power consumption of the network resources in each round of data gathering and communicating. The proposed algorithm is a cluster_ based routing algorithm that exploits the redundancy properties of the sensor networks in ...
