the task of optimally assigning military ordinance to enemy targets, often termed weapon target allocation (wta) problem, has become a major focus of modern military thought where a cost effective allocation is required without degrading the required kill performance. the paper presents three main weapon allocation techniques namely uniform weapon allocation, first-in-first weapon allocation an...

in today's communities achieving to effectiveness of urban advertising is one of troubles of advertisement industry. this research is trying to answer this question that using three-dimensional design in urban advertising has what place in urban field? this query has been conducted in the method of iconological analysis on chosen urban advertising works of last 15 years in the world with t...

the paper discusses the current state of research concerning railway network timetabling and traffic management. timetable effectiveness is governed by frequency, regularity, accurate running, recovery and layover times, as well as minimal headway, buffer times and waiting times. analytic (queuing) models and stochastic microsimulation are predominantly used for estimation of waiting times and ...

In this paper we study microstrip antenna miniaturization using partial filling of the antenna volume with dielectric materials. An analytical expression is derived for the quality factor of an antenna loaded with a combination of two different materials. This expression can be used to optimize the filling pattern for the design that most efficiently retains the impedance bandwidth after size r...

These modes of analysis [cost-effectiveness and cost-benefit] are neither good for nothing nor good for everything, and one cannot speak of them as wholly good or bad. It is much more useful to try to specify some conditions under which they would or would not be helpful for various purposes.

background: dna extraction is one the most important steps for molecular analysis of food-borne pathogens. in this research, three methods of dna extractions from beef harboring sarcocystis spp. were compared for the quality, quantity, safety, as well as cost-effectiveness. methods: about 100 mg intersostal and diaphragm were collected from 10 slaughtered cattle. after ensuring their contaminat...

This article compares the relationship between patent quality and patent value in discrete and cumulative innovation. Using factor analysis and a set of various commonly used patent quality indicators including claims, citations and family size, we build a quality factor jointly driving all indicators for 9255 patents. We then test the significance of this quality factor for predicting patent r...
