Abstract: The orbit transfer problems using impulsive thrusters have attracted researchers for a long time [3]. One of the objectives in these problems is to find the optimal fuel orbit transfer between two orbits, generally inclined eccentric orbits. The optimal two-impulse orbit transfer problem poses multiple local optima, and classical optimization methods find only local optimum solution. McCue [7] solved the problem of optimal two-impulse orbit transfer using a combination between numerical search and steepest descent optimization procedures. The transfer of satellites in too high orbits as geosynchronous one (geostationary), usually is achieved firstly by launching the satellite in Low Earth Orbit (LEO) (Parking orbit), then in elliptical transfer orbit and finally to the final orbit (Working orbit). The three steps process is known as Hohmann transfer. The Hohmann transfer which involves two circular orbits with different orbital inclinations is known as non‐coplanar Hohmann transfer. If both orbital planes are aligned the Hohmann transfer is known as coplanar what is further considered in this paper. In terms of propellant consumptions the Hohmann transfer is the best known transfer to be applied when transferring between elliptical coplanar orbits. For transfer between elliptical coplanar orbits, the given information usually consists of the altitude of perigee and apogee of the initial and the altitude of perigee and apogee of the final orbits. The velocity to be applied into two orbit points in order to attain the dedicated final orbit is analyzed.
The aim of this paper is compare between three types of coplanar impulsive transfer (two impulses, three impulses and one tangent burn) and conclude about the velocity changes for these types under relation between initial low Earth altitudes and final orbit. For the relation between initial orbit altitudes and final orbit altitude, the velocities to be applied in process of Hohmann transfer are simulated. From respective simulations, the velocity variations on dependence of this relation are derived. And the time of flight is considered too. The problem of spacecraft orbit transfer with minimum fuel consumption is considered, in terms of testing numerical solutions.

Abstract:In health care domain, data mining plays a vital role for predicting diseases. For detecting a disease number of tests should be required from the patient but number of test should be reduced while using data mining techniques. The data mining technique analyze the test parameters and it concludes the associative relation between the parameters that reduces the tests and the reduced test plays key role in time and performance.  In this study medical terms such as sex, blood pressure, and cholesterol like nineteen input attributes are used. In this paper association among various attributes which are the causative factors of heart diseases are analyzed. The patient’s records are observed before prediction and the factors are grouped as per its severity level. In this system the level of causative factors are categorized using K-Means clustering technique and it distinguishes the risky and non-risky factors. Frequent risk factors are mined from the clinical heart database using Apriori algorithm. The risk factors are taken for this study to predict the risk level and find the co-ordination among the factors that helps the medical people to predict the disease with minimum tests and treatments.

Abstract: Microbial fuel cells (MFCs) are alternative source of producing electricity, yet not commercialized but they shows production of electricity. The power produce by this experiment is limited but can be consider for future aspect. This research carried out by various samples which show positive result. , its due to metabolic activity which carried out in the anaerobic condition MFCs production of electricity is indirectly proportional to time. This can be seen in all samples. The experiment is carried out by construction of two-chamber, in which transfer of energy was carried out. The power production of the main mechanism in this experiment was by direct transfer of electrons to the electrode by bacteria growing on the electrode cyclic voltammeter. The attachment of bacteria on electrode was studied. The most bacteria which were isolated from the sample were Klebsiella pneumonia, Escherichia coli, Pseudomonas aeruginosa.

Abstract: The ever increasing levels of electronic waste (e-waste) and limited capacities for disposal and recycling have worsened e-waste management in Kenya. An understanding of end-user of electronic devices (consumer) participation is fundamental in planning for e-waste management as Kenya has a pending bill on e-waste management since 2013 that stipulates the role of consumers in e-waste management. There is need to understand factors influencing willingness to recycle to inform policy. Various studies suggest socio-economic, demographic and individual preferences influence participation by consumers. Our study relied on Kisumu municipality registry (N = 1,193) to get a sample of businesses and offices to be surveyed in the Central Business District. Using multiple regression model, the authors found factors that influence participation in e-waste drop-off schemes are Income, Education, Gender and Recycling habit but not Age and Awareness levels. Our results suggest that Economic instruments such as deposit and refund programs for e-waste drop-off should be embraced by waste planners to encourage low income earners to participate, there is need for civil education on the benefits.
