Power shortage and unstable power supply remain serious problems. Conventional cooling technologies that utilize harmful refrigerants consume more energy and cause peak loads leading to negative environmental impacts. As the world grapples with the energy and environmental crisis, there is an urgent need to develop and promote environmentally benign sustainable cooling technologies. Solar cooling is one such promising technology, given the fact that solar energy is the cheapest and widely available renewable energy that matches the cooling load requirements. Thermal storage systems are essential to overcome the disadvantage of the intermittent nature of solar energy and variation in cooling demand. The enhanced utilization of solar energy and other consequences of thermal storage integrated systems have gained the attention of researchers in the recent years. This paper reviews research articles in the field of solar cooling techniques, solar collectors, storage methods and their integration, along with performance improvement studies reported using thermal stratification and cascaded thermal storage systems. © 2011 Elsevier Ltd.

This paper deals with the fabrication and mechanical investigation of aluminium alloy, alumina (Al2O3) and boron carbide metal matrix composites. Aluminium is the matrix metal having properties like light weight, high strength and ease of machinability. Alumina which has better wear resistance, high strength, hardness and boron carbide which has excellent hardness and fracture toughness are added as reinforcements. Here, the fabrication is done by stir casting which involves mixing the required quantities of additives into stirred molten aluminium. After solidification, the samples are prepared and tested to find the various mechanical properties like tensile, flexural, impact and hardness. The internal structure of the composite is observed using Scanning Electron Microscope (SEM). © 2014 Elsevier Ltd.

Hybrid materials of any kind are the keynote for today's demands. This paper deals with one of such hybrid composite made of natural fibres namely, banana and flax fibres. The structural build-up is such that one layer of banana fibre is sandwiched between two layers of flax fibres by hand layup method with a volume fraction of 40% using Epoxy resin and HY951 hardener. Glass fibre reinforcement polymer (GFRP) is used for lamination on both sides. This lamination also increases the overall mechanical properties along with better surface properties. The properties of this hybrid composite are determined by testing its tensile, impact, and flexural loads using a Universal testing machine. Thermal properties are analysed and hybrid composites of flax and banana with GFRP have better thermal stability and flame resistance over flax, banana with GFRP single fibre hybrid composites. Morphological analysis is done using Scanning Electron Microscope (SEM). The result of test shows that hybrid composite has far better properties than single fibre glass reinforced composite under impact and flexural loads. However it is found that the hybrid composite have better strength as compared to single fibre composites. © 2014 Elsevier Ltd.

Cloud computing is one of the fast spreading technologies for providing utility based IT services to users. These services are provided by large-scale virtualised data centers. As it is these data centers consume large amount of electrical energy for their operation and maintenance. Extensive research had been undertaken to reduce the power consumption of data center by bringing changes in the hardware technology of data center. Alternatively, virtualization can also be used to reduce the power consumption in a data center. Migration of virtual machines(VM), one of the key feature of virtualization can be used to consolidate workloads on fewer servers and thus switch off idle servers to conserve energy. The major concern in any server consolidation technique is the optimal choice of physical server for VM placement. This paper aims to summarise the available VM placement algorithm that takes into consideration the power consumption factor during VM migration. A survey of various solutions to VM placement based on bin packing strategy is discussed. © 2013 IEEE.

In the next generation of wireless networks, the entire network operating on different radio frequencies under wireless mode will be available for communication. The rapidly growing demand for "any service - anywhere - anytime" high-speed access to IP-based services is becoming one of the major challenges for mobile networks. However, in several situations, mobile terminals tend to associate with networks guaranteeing the best performances to stay "Always Best Connected" which leads to overload the most attractive technology while keeping the others technologies underutilized. As a recent research focus, load balancing is one of the key technologies in the convergence of heterogeneous wireless networks. Load balancing is a significant method to achieve the resource sharing over heterogeneous wireless networks, and it can improve resource utilization, enlarge system capacity, as well as provide better services for users. When dealing with high speed traffic over heterogeneous, we propose a load balancing algorithm using novel approach. For wireless packet network, this novel load metric is based on the packet scheduling and the radio link quality information. The solution can be used in on-line system because it requires less computation time and it operates in a distributed way instead of a usual centralized way. The two main targets of the proposed algorithm are the admission control and the network initiated handover. Further we have to investigate the joint load balancing and resource allocation optimization in heterogeneous networks. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2012.
