Abstract

Klein-4 or Klein-V group is a group with four elements including identity. The binary operation on Klein-4 group will produce identitiy if operated to it self and produce another non-identity element if operated to another non-identity element. The focus of this paper is to explain the principle of Klein-4 group on Domino card and also find all complete possible elements. Domino card is a set of 28 cards which the surface of each card divided in two identic boxes contain combination of dots as pattern. The final part of this research is to find out all possible combination of cards which can be used as elements of a Klein-4 groups.

Abstract

An option is a financial instrument in which two parties agree to exchange assets at a price or strike and the date or maturity is predetermined. Options can provide investors with information to set strategies so they can increase profits and reduce risk. Option prices need to be accurately evaluated according to reality and quickly so that the resulting value can be utilized at the best momentum. Valuation of option prices can use the Heston equation model which has advantages compared to other equation models because the assumption of volatility is not constant with time or stochastic volatility. The volatility that is not constant with time corresponds to reality because the underlying asset as a basis can experience fluctuations. The Heston equation has a disadvantage because it is a derivative equation that is difficult to solve. One way to solve derivative equations easily is to use a numerical solution to the finite difference method of non-uniform grids because the Heston equation can be assumed to be a parabolic equation. The numerical solution of the finite difference method can solve derivative equations flexibly and do not require matrix processing. But it requires a heavy and slow computing process because there are many elements of calculation and iteration. This study proposes a numerical solution to the finite difference method by using the Compute Unified Device Architecture (CUDA) parallel programming to solve the Heston equation model that applies the concept of stochastic volatility to get accurate and fast results. The results of this research proved 15.52 times faster in conducting parallel computing processes with error of 0.0016..

Abstract

Smart Campus is an android mobile application that has strong features to facilitates students, faculties, admins, parents, and managers. It provides a comprehensive integrated solution to improve the overall performance of the college. The use of mobile applications is increasing day by day. We all use mobile application in a lot of things in our daily life. We came up with an idea of building an application that will help the students and faculty member to accesses the system as fast as possible. In this study, we will discuss the problem and propose a solution to it, as we will talk about the planning phase and its component, requirements the functional and non-functional with its Data Flow Diagram, etc. We also design the interfaces. This mobile application will help the students and faculty members to do the tasks in the minimum time.

Abstract

Drinking water is one of the main needs of human life. Water sources do not always have the feasibility to drink. Distillation is one way to obtain potable water. Distillation can influence on drinking water quality. Low performance is a major problem in distillation. One way to improve performance is by increasing the input water temperature. One way to increase the input water temperature by utilizing heat energy on the cover glass. This study aims to improve the performance of solar energy water distillation and input water temperature by a heat exchanger. This research method is experimental. The measured variables are absorber temperature in the distillation model (T1), glass temperature (T2), ambient temperature (Ta), amount of distilled water produced (m) and heat energy coming from solar energy (G). This research uses variations, namely with a white or black heat exchanger and without heat exchanger. Water quality tested using 4 parameters such as microbiology, inorganic chemistry, physical and chemical. Based on this study, the best results produced by a black heat exchanger using a water flow rate of 2 l/h which produce distillation water 422 ml (480 ml/(m2.h)) and efficiency value of 79.74%. While the best results using white heat exchanger is using 0.7 l / hour water flow rate which produces distillation water of 497 ml/(m2.h) and efficiency value of 82.63%, Distilled water has increased in quality even though it has not met the standards No. 492 of 2010Keywords: distillation, solar energy, glass cover, water quality, efficiency

Abstract

A design phase commonly initiates either a product invention or development. Before it continues to the fabrication steps, a modern computational, enabling a simulation study during the phase, often gives opportunity to develop its effectiveness and efficiency. Through several boundary conditions, some analytical and/or computational approaches could be determined. This paper aims to elaborate both static simulations and simple experimental tests on an electric automobile chassis prototype. An application based on finite element analysis was assessed to carry out both von Misses stresses and the nodal displacements regarding the construction and/or material strength to a static loads mode. Furthermore, an experimental based examination was also executed as a simple physical validation. The studies emphasize accepted results on von Misses stresses and nodal displacements for both simulation and experimental approaches.Keywords: Chassis Statics, von Misses stresses, nodal displacements, finite element

Abstract

In the Calculus, a definite integral can be used to calculate the area between curves and coordinate axes at certain intervals; surface area and volume formed if an area is rotated against the coordinate axis. Problems arise if you want to calculate the area of the area bounded by a curve and a line that does not form an angle of 0 or 90 degree to the coordinate axis, as well as the calculation of the volume of objects and the surface area of a revolution axis of rotation is a slanted line. By using existing definitions, a formula is developed for this purpose.

Abstract

A set of data pattern that have the characteristic of a function can be approached using Newton series simulation. When using the Newton series, the simulation result of the summation of extrapolation data can be gradually done in step by step. However, if using the IN series, the simulation result of the summation of extrapolation data doesnt need to be gradually done in step by step. The methodology in this research compares the data pattern from the simulation results of the high degree function with the results of interpolation and extrapolation from the results of the IN series simulation. Futhermore, will be carried out comparison simulation analysis of the summation of the function values gradually with the extrapolation function directly using the IN series. The result of comparison simulation analysis point out that the value of the total summation of data between the gradual and the direct summation is the same, so that the direct sum technique using the IN Series is able to make the total sum process more efficient.

Abstract

Inverse problems deal with recovering the causes for a desired or given effect. Their presence across sciences and their theoretical study can be traced to a classic example. Moreover, their ill-posedness motivates computational methods to solve them, and we give a very humble introduction to them. In relation we discuss their active research trends!
