On Retention of Eventual Stability of Perturbed Impulsive Differential Systems

In this paper, a system of non nonlinear differential equations withimpulse effect at fixed time moments is considered and criteria for retention ofuniform eventual stability of its perturbed impulsive differential systems undervanishing perturbations are established. Sufficient conditions are obtained byusing piecewise continuous Lyapunov functions. An example is also worked outto illustrate the results.AMS Subject Classification: 34CXX, 34DXX, 34A37, 34K45

Povrsinški plazmonski sateliti u spektrima fotoemisije iz sredica u spojevima kasnih prijelaznih metala

The origin of satellites in 2p core level of late transition metal compounds are studied using plasmon theory. The calculated values of energy separation and relative intensity agree well with the experimental values and the theoretical calculations by Kozo Okada et al. The excitation of surface plasmons in 2p core level X-ray photoemission spectra of transition metal dihalides is discussed.Proučavamo nastanak satelita 2p sredice spojeva kasnih prijelaznih metala primjenom plazmonske teorije. Izračunate vrijednosti pomaka energije i relativnih intenziteta u dobrom su skladu s eksperimentalnima i s teorijskim vrijednostima Kozo Okade i sur. Raspravljamo uzbudu površinskih plazmona rentgenskim zračenjem u fotoemisijskim spektrima 2p sredice dihalida prijelaznih metala

On Certain Gluing of semigroup rings and indispensable resolution of semigroup rings

In this paper, our aim is twofold: First, by using the technique of gluing semigroups, we give infinitely many families of a projective closure with the Cohen-Macaulay (Gorenstein) property. Also, we give an effective technique for constructing large families of one dimensional Gorenstein local rings associated to monomial curves, which supports Rossi question, saying that every Gorenstein local ring has a non-decreasing Hilbert function. In the second part, we study strong indispensable minimal free resolutions of semigroup rings, focusing on the operation of the join of affine semigroups, which provide class of examples supporting Charalambous and Thoma question on the class of lattice ideal which has a strong indispensable free resolution.Comment: 12 Pages, comments are welcom

Extended 16x16 Play-Fair Algorithm for Secure Key Exchange Using RSA Algorithm

With the world entering in the 21st century rigorous efforts are being made to secure data and flow of information among the users. Though with the advancements are fast and efficient the third party intervention and security threats has also increased many folds. The algorithms being used to encrypt and decrypt data needs to be strong enough to secure the data but also simple enough for a user to handle the process. With this article a novel, practical approach is presented which not only makes the information more secured but also being based on RSA algorithm is easy enough for users to understand and implement into the systems

Fabrication and Simulating Solar Cell Devices using Silvaco TCAD Tools

Solar cells are p-i-n photodiodes, which are operated under forward bias. The intention is to convert the incoming optical power into electrical power with maximum efficiency. In this paper we are going to design a solar cell and simulation of solar cell using the Silvaco TCAD tools. Silvaco TCAD refers to Technology Computer-Aided Design. This means that computer simulations are used to develop and optimize semiconductor processing technologies and devices. As TCAD simulations solve fundamental, physical partial differential equations, such as Poisson, Diffusion and Transport equations in a semiconductor device. This deep physical approach gives TCAD simulation predictive accuracy. It is therefore possible to substitute TCAD simulations for costly and time-consuming test wafer runs when developing and characterizing a new semiconductor device or technology. Keywords- photodiode, Silvaco TCAD Tools
