Cooling sector is dominating by vapor compression cooling sector which uses refrigerant which are harmful to environment. The solar ejector cooling system is alternative for vapor compression cycle which uses solar energy to give heat to the generator, which is a viable method for heat generation. The solar ejector cooling system not only fulfills cooling requirement but also helps in energy conservation and protection of environment. It reduces the generator work and decrease the throttling losses. Maintenance requirement and cost is low for ejector cooling system .In this paper, theoretically study is done on enhancement of the performance of solar ejector cooling system. Various system configuration are presented with detailed design. This system still needed a lot of research work to make it alternative for vapor compression cycle based cooling system completely.

This work intends to analyze the processes of flexibility to improve the adaptability to the users and to define some strategies to delay building obsolescence. Some approaches that address the architectural flexibility processes are studied to understand the rapid transformation of user lifestyles and changes in needs and performance building requirements. Obsolescence is often characterized by the lack of flexibility in the structure and walls, as well as services that change rapidly according to the different uses of buildings. This poses a threat to the built environment, since a large number of buildings are demolished having still years of useful life. In this way, different types of obsolescence are analyzed, focusing on some structural, economic, functional and social aspects of the construction and the use of buildings, seeking the capacity to design and produce adaptive buildings that are more resilient to obsolescence.............

Adi Sucipto Airport-Jogyakarta is an airport with enclave civil status or as TNI-AU airbase (civilian airport within the military area) has limited infrastructure with Azimuth Runway 09-27, has no RESA (Runway End Safety Area). The calculation results using Acceptable Safety Level (ASL) standard 1 x 10-7 shows that the probability of accident risk at wet runway condition is greater than in dry condition. Runway Excursion occurs at the airport, especially when the runway is wet and overrun due to hydroplaning and the plane deviates from the center of runway as well as the aircraft wheels are in contact with ground or obstacle surface outside the runway. It means the thicker layer of water above the runway will cause increased risk of accidents on the runway. This is why standing water should be immediately removed from the runway as quickly as possible..............

The problems of constructing optimal adaptive onboard color RGB depictingUAV systems have been analyzed. The problem of optimal formation of color signals of RGB color system has been formulated and solved by implementing the adaptive flight mode of UAVs containing an onboard imaging system. An adaptive UAV mode with an imaging system on board is proposed, which consists of adaptive changes in flight altitude depending on the wavelength of the received color signal. As a result of the optimization of the proposed operating mode of the UAV imaging system, an analytic formula for adaptive device control has been obtained. Recommendations have been given on the practical implementation of the proposed method.

The study aimed at findingout the customer satisfaction level of services provided by five star hotels and find out theservice areas in which customers are not satisfied i.e. there is a service gap that needs to be taken care. The study was conducted with special reference to the Hotel Taj-Vivanta by using survey method to understand the level of satisfaction of the current customers staying at the hotel and the customers who had stayed in the hotel in the last month. The sample size randomly taken from the population was 200 respondents, who were requested to fill up the Questionnaire. The hotel staff of the chain in Lucknow region cooperated in order to find out the areas of improvement vis-à-vis their competitors...............

Drying of three agricultural products namely potato slices, onion slices and whole grapes was done using an indigenously designed and fabricated forced convection indirect solar dryer and under open sunlight. The diurnal variation of temperature, relative humidity in the solar dryer was also compared with the ambient temperature and relative humidity during March and April 2017 for all the three products. The study showed increase of temperature and lower humidity inside the drying chamber at different time interval. Hourly moisture loss for all the three agricultural products in the drying chamber and open sun drying was also compared and the percentage of moisture loss in the drying chamber was found to be higher compared..............

Sorting data is one of the most important problems that play an important rule in many applications in operations research and computer science. Many sorting algorithms are well studied but the problem is not to find a way or algorithm to sort elements, but to find an efficiently way to sort elements. The output is a stream of data in time. We are interested in this flow of data. For the performance of such algorithms, there has been little research on their stochastic behavior and mathematical properties.In this paper we study the mathematical behavior of some different versions sorting algorithms. We also discuss the corresponding running time using some different strategies.

The purpose of this study is to investigate internal and external influences on consumers purchasing decisions on cosmetic products in NCR for the two competing brands Kama and Kara. The questionnaires were given to 150 consumers who are all using these brands. The instruments of this study involved two parts: the first section of the instrument consisted of forced-choice questions about demographic characteristics: gender, marital status, age, occupation, monthly income level. The second section variables chosen for this study in order to measure the influence of consumer buying behaviour in cosmetics products. The Statistical Package for the Social Science (SPSS) for Microsoft Windows 20.00 was used to complete the analysis of the collected data. Descriptive statistics..............
