Finite Element Analysis (FEA) is an important engineering tool used to assist in approximating and verifying how a component will react under various external and internal loading conditions. The purpose of this master of engineering project is to investigate and analyze fully elastic and elastic-plastic deformation of a High Strength Steel (HSS) tensile test specimen in FEA ANSYS under various conditions. In general, material selection is a key component to engineering analysis.

The aim of the research was to determine the effects of Anhydrous ammonia application on yield and yield components of sunflower. Field experiment was conducted in Tekirdag at Trakya Region, Turkey during 2014 and 2015. Three different methods was planned. Anhydrous ammonia application (M1), the traditional condition (M2) and the control (M3). Anhydrous ammonia application was made once before the sowing period. At the M2 is the method used by local farmers. No nitrogen fertilization was at the M3 method.

In this paper we present a concrete method to estimate the moments of time of ruin, surplus immediately before the ruin and deficit at ruin under two way renewal process. Gerber–Shiu discounted penalty function are used to estimate the same. Laplace transform is taken into account while calculating the moment. Furthermore, Lindley distribution is being assumed as the distribution of the claim amount .This approach allows for the experimentation of various distribution forms among the eventual random variables.

Data transfer from one server to another needs a great ontology process in which data from one server to another gets migrated with a protocol service in which three layers are minimum required. In this work, focus on migrating the particular application data. Cloud creates a series of mechanical, architectural and legal challenge that the State of the Art attempts to address. Arrange such efforts into a set of migration scenarios and connect them with a list of reusable results for the application data migration in the form of patterns.

In this study, we apply Grey System Theory-GM (1, 1) based on the statistics provided by the Vietnam dairy Products Joint-Stock Company (Vinamilk) from 2009 to 2016 and make prediction values for two years, i.e., 2017 and 2018. The results which help enterprises to figure out the target in the near future are shown with low tolerance proven by Mean Absolute Percent Error (MAPE).

In this study; basically the design of a 1KVA tubular linear alternator has been carried out for a free mechanical piston and internal combustion engine. In the conducted design, the conformity of the optimization data has been examined with finite elements method and the geometrical dimensionings of the designed alternator have been determined with a developed analytical calculation program.

In this paper, an analysis is presented the effects of chemical reaction parameter variable thermal conductivity and radiation on the flow and heat transfer of an electrically conducting micropolar nanofluid over a continuously stretching surface with varying temperature in the presence of a magnetic field.  The surface temperature is assumed to vary as a power-law temperature. The governing conservation equations of mass, momentum, angular momentum and energy are converted into a system of non-linear ordinary differential equations by means of similarity transformation.

Ancient India, an important role in the development of chemistry was made by Ayurveda which used a variety of minerals. Science and technology in ancient and medieval India covered all the major branches of human knowledge and activities. In any, early civilization, metallurgy has remained an activity central to all civilizations from the Bronze Age and the Iron Age, to all other civilizations that followed. The Indus valley civilization was the earliest society, the story of early chemistry in India begins from here. Traces of cement had been ford in the era of Mohanjodaro.

Dy3+ doped lithium borate (LB) glasses with compositions (in mol %) (60-x) B2O3+ 20LiF + 10MgF2 + 10ZnO + xDy2O3 (where x = 0.1, 0.5, 1.0, 1.5 and 2 mol%) were prepared by melt quenching technique and have been investigated using structural measurements, optical absorption, luminescence, and decay kinetic techniques as well as Judd–Ofelt (J–O) analysis. The structure of host glass system can be accessed from XRD and Raman graphs. For these glasses, optical absorption, emission and decay measurements were carried out.

This paper explains the selection procedure for Skip lot-sampling plan of type SkSP-R which use Multiple Repetitive Group Sampling (MRGS) plan as reference plan through relative slopes at various points on the OC curve, which describes the degree of steepness of the OC curve.
