At present, the data center is widespread in energy intensive and serious resource waste and other issues. How to efficiently integrate computing resources and reduce the energy consumption cost is a hotspot of research on the data center. Because of virtualization technology can achieve the efficient use of resources and simple management, so widely used in data center energy saving algorithm based on virtual machine migration on resource allocation and scheduling, implementation resource on the server load balance and reduce energy consumption of data centers. However, most existing algorithms for data center energy saving without considering the energy consumption of the virtual machine migration between server costs, excessive reliance on virtual machine migration can realize the average allocation of resources, but is likely to reach the purpose of reduce system energy consumption. Therefore, research on the energy consumption in the process of virtual machine migration overhead and reasonable design of energy-saving scheduling algorithm for data center power management is of great significance.

In this paper to compensate for the current stress for Induction Motor Drive , a novel current limit strategy with  minimized DC-Link capacitor is proposed. In order to avoid excessive pumping up in dc-link voltage during the occurrence of a fault, the conventional all-turn-off current limit logic is replaced and there by  eliminating the reversal dc-link current. For this a low cost fault tolerant  control strategy, based on a quasi-cycloconverter method  is proposed as a potential solution for overcoming the reversal dc-link current. In this configuration, along the PWM drive, the three-phase Induction motor terminals are connected to the ac supply mains  through  a group of back-to-back connected SCRs which can even provide a speed control at selectable frequencies by controlling the switching patterns of a SCR switches by adjusting the frequency and the firing angles of the SCRs . The proposed design stands out as it is used for mitigating all driver faults along with elimination of reversal dc-link current with very minimal hardware modifications  and there by providing system compactness, reliability as well as cost effectiveness. This proposed control strategy is verified by simulating using the software Matlab-Simulink and desirous waveforms for DC link current and voltage along with speed torque waveforms are obtained.

Technology improvements are happening on a day to day basis. In order to grow, we need to update ourselves, so as the main aim of this paper. We see vehicles on road moving in one lane as a chain sometimes and out of chain the other. We aim to bring this under control by using the Algorithms of latest technological advancements in the field of electronics and computer sciences. The whole idea is to make communication between the vehicles possible using electronic devices like IR Transmitters and IR receivers, Pulse encoders and Decoder and an Android application connected to a central server to map the movement of the vehicles. This is made possible by using Data Analysis, Control of Vehicles and an Android application using the centralized server located remotely in another location. When the vehicles travel in one particular lane where there is traffic ahead, they are instructed to change the lane to avoid it and prevent dead lock traffic jams and accidents.

One of the most important challenges that need to be currently faced in securing resource-constrained embedded systems is optimizing the trade-off between resources used and security requirements. Security is constantly evolving as threats change over time. As a device becomes popular exists in the market longer, it becomes more susceptible to attack. Many devices in the past were not designed to be field programmable or accept updates without significant modifications. Those days are gone. Devices today must be field upgradeable to not only change and improve functionality, but to deal with bugs and security issues. Including security planning in the life cycle management of your device is critical. Moreover, it’s important that your organization deal with security vulnerabilities as they arise with high priority and rapid response times. This paper first surveys the current situation and then proposes a approach where security is considered from the beginning of the Embedded systems development approach. Obviously, prevention is not the complete solution. A 5-level security strategy assures not only that a system has been properly designed in terms of security, but also that the liabilities of its designers are adequately covered.

The aim of this paper is to present funding opportunities for investments with private capital participation for urban mobility Infrastructure, through Project Finance. This model searches to bring economic fundamentals of engineering, making it possible for the participation of private sector in the financing of projects of the Urban Mobility Plans of Brazilian cities. The Brazilian experience refers to a strong dependence on public funding, that even demonstrating great strides in financial structures in the past, nowadays is proven to be insufficient to meet the demands of infrastructure investments, among them, those related to urban mobility. It was noticed that there is a very big effort and success in obtaining funds but without the effective concern with economic and financial sustainability of the projects, i.e., after deployment. Unfortunately, both in Brazil and in other countries, it is observed a myopic view of urban mobility, taking into consideration only the financing of infrastructure to meet the mobility of passengers, at the expense of mobility. However, Urban Operations have practical conditions of a systemic view, due to the way that occurs to their deployment planning, being possible to identify goods supply demands in the region, allowing the systemic vision of the mobility that the major cities around the world need.

Fly ash is a waste by-product extracted by mechanical / electrostatic precipitator, obtained from coal fired power plants. In India most of the thermal power plants are utilizing bituminous or sub-bituminous coal for generation of electricity. Fly ash is the by-product of burning these types of coal. Utilization of low grade coal, having 35% to 55% of ash content results in bulk production of fly ash. It is estimated that in the year 2012 A.D. annual production of fly ash may reach 140 million tons. The quality and quantity of fly ash depends on Coal type and purity, Degree of pulverization of coal,Boiler type and operation, Air / fuel ratio and effectiveness of mixing the same and collection and stockpiling methods.

In India Only 3% to 5% of the fly ash produced annually is utilized effectively. The unutilized large quantity requires special attention of researchers to identify the ways of bulk utilization of fly ash.

In the present study experiments were carried out to understand the strength characteristics of stabilized and unstabilized fly ash. Ordinary Portland cement and Crumbed Rubber were used as stabilizers. Different percentages of stabilizers were used for different tests. These percentages are – 6%, 8%, 10%, 12% and crumbed rubber was used 5%.

Flash floods is one of the major natural hazards that affect the socio-economic practices. Wadi Dahab is one of the major attraction sites for touristic activities in Egypt that contribute to the local economy, however, it is subjected to sever flash flood events. This research aimed at exploring the possibilities of developing mitigation measures for preventing flood damages in Wadi Dahab. Complementary to the city plan, three mitigation scenarios were proposed 1) historical scenario (2010) which proposed 7 dams and 3 reservoirs; 2) actual situation scenario (2014) which proposed 8 dams and 5 reservoirs; and 3) future planning scenario which proposes building three new dams, three artificial lakes and two retention walls. MIKE 21 and LISFLOOD-FP models were used to generate the flood extent for each scenario. Satellite data was used to estimate the current situation with other thematic maps. The outcomes of the three scenarios were comprehensively compared to understand the actual impact on the residential area and estimate the economic losses from land cover and residential buildings in Dahab city.  Finally, it is well understood that the current mitigation measures are not sufficient to assure the safety of the city against the flash floods and more structural measures are recommended according to the third proposed scenario.

This paper reveals the focus of the study of marble dust as replacement material in concrete. Marble has been commonly used as a building material since the ancient times, In building industry. The disposal of the marble powder material, consisting of very fine powder, constitutes one of the environmental problems around the world. Marble blocks are cut into smaller blocks in order to give them the desired smooth shape. In India, marble dust is settled by sedimentation and then dumped away which results in environmental pollution, in addition to forming dust in summer and threatening both agriculture and public health. Therefore, utilization of the marble dust in various industrial sectors especially the construction, agriculture, glass and paper industries would help to protect the environment. For instance, certain residues such as marble sludge from stony material manufacturing and cement kiln dust are characterized by an average diameter. This important characteristic makes them potentially candidates for use in the production of self-levelling mortars (SLMs) and self-compacting concretes (SCCs). They can be compacted under their self-weight, with no external action, providing a considerable saving in time and energy.
