background : to date, 36 years has passed since the beginning of measles vaccination; the disease is still circulating around the world, threatening lives of human beings especially in developing countries. in recent years, we have confronted measles in previously vaccinated adults from all over the country. objective: to find out if there is a need for changing our routine measles vaccinati...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
The Cauchy-Davenport theorem states that for any two nonempty subsets A andB of Z/pZ we have |A + B| ≥ min{p, |A| + |B| − 1}, where A + B := {a + bmod p | a ∈ A, b ∈ B}. We generalize this result from Z/pZ to arbitrary finite(including non-abelian) groups. This result from early in 2006 is independent ofGyula Károlyi’s 2005 result in [13] and uses different methods.
in the first chapter we study the necessary background of structure of commutators of operators and show what the commutator of two operators on a separable hilbert space looks like. in the second chapter we study basic property of jb and jb-algebras, jc and jc-algebras. the purpose of this chapter is to describe derivations of reversible jc-algebras in term of derivations of b (h) which are we...
A utility function is an important tool for representing a DM’s preference. We adjoin utility functions to multi-objective optimization problems. In current studies, usually one utility function is used for each objective function. Situations may arise for a goal to have multiple utility functions. Here, we consider a constrained multi-objective problem with each objective having multiple utili...
in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
