In this paper, two non-linear technologies are proposed based on weak disposability definitions: weak disposability with non-uniform abatement factors and new weak disposability. Both technologies are applied to Spanish airport systems and the existing technologies are modified. To remove the computational complexity of non-linear approaches, the linearization methods are proposed. Then, in ord...
Abstract Background : Although, different studies on end-to-side nerve repair, results are controversial. The importance of this method in case is unavailability of proximal nerve. In this method, donor nerves also remain intact and without injury. In compare to other classic procedures, end-to-side repair is not much time consuming and needs less dissection. Overall, the previous studies i...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
This lecture gives a general introduction of graph partitioning problems. We will begin with the definitions of some classic graph partitioning problems (e.g. multiway cut, multicut, sparsest cut), and discuss their relationships. Then we will focus on deriving two approximation algorithms. For the multiway cut problem, we will show a 2-approximation algorithm through a combinatorial argument. ...
Childhood obesity is considered a major issue because of its high prevalence and because of its severe consequences on adult health. Prevalence studies are carried out in numerous countries. Analysis of time trends and geographic comparisons are particularly useful, as they may help to identify factors promoting obesity. These studies require adequate definitions of nutritional status and stand...
teachers’ beliefs greatly influence their performance in the classroom, their choice of instructional strategies, their way of controlling the class, their dealing with the students, and their general goals and objectives. one of these beliefs is teachers’ sense of efficacy which is viewed as an important construct and has shown to be positively correlated with students’ achievement (ross, 1992...
one of the main important and challenging issues in substance use disorders is the comorbidity of diseases. in fact, substance use disorder falls into a special circumstance that is unlike any other disease in medical science. substance abuse patients typically and on purpose use illegal drugs (poison) in aim of damaging their nervous system and change function of their brains by applying subst...
Cut-elimination is the most prominent form of proof transformation in logic. The elimination of cuts in formal proofs corresponds to the removal of intermediate statements (lemmas) in mathematical proofs. The cut-elimination method CERES (cut-elimination by resolution) works by constructing a set of clauses from a proof with cuts. Any resolution refutation of this set then serves as a skeleton ...
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...
