Present paper discusses the working methodologies used for drop test. Engineers widely used physical testing method to investigate the behaviour of cellular phone during drop test. It is very costly, time consuming and complex. Finite element analysis provides numerical models without spent so much money on physical testing methods. Drop test simulation is one of the important tool uses for the...

with increasing competition in today’s markets, the vital point for companies is to maintain their market shares. therefore, marketers try to vitalize the companies’ brands, in order to maintain their position in market. whereas, creation a new brand is very costly and time consuming and its chance of success is limited, nowadays, more than ever, marketers are trying to achieve their goals thro...

cation exchange capacity and specific surface area are among some of the important soil characteristics the direct measurement of which is laborious, costly and time consuming. therefore, fractal dimension of particle size distribution has been widely studied in relation with many such dynamic and static processes as transmission of water and solutes, water holding capacity, heat storage and co...

water balance components are difficult to measure in short intervals because their measurement is time consuming and costly. therefore, soil-water--plant models can be used for prediction of these components. in this study, to predict grain yield and evaluate water use efficiency, an agro-hydrological model, namely, swap was used. this study covered a 10-years period from 2000-2010. based on th...

In India, vehicles on the road are increasing very rapidly. Either more infrastructures required to meet needs of an increase in which costly and time-consuming projects. An intelligent transportation system can also overcome traffic other related problems. this paper, developments achievements India taken into consideration. Some projects listed, recent services added Intelligent Transportatio...

abstarct precise knowledge of all components of water balance is essential to optimize water use in irrigated agriculture. however, water balance components are difficult to measure in required time intervals because their measuring is time consuming and costly. unsaturated zone simulator models are useful tools for predicting the effects of agricultural management on crop water use and can be ...

background: one issue of concern in water supply is the quality of water. measuring the qualitative parameters of water is time-consuming and costly. predicting these parameters using various models leads to a reduction in related expenses and the presentation of overall and comprehensive statistics for water resource management. methods: the present study used an artificial neural network (ann...

furrow irrigation is the most common type of surface irrigation. determine the advance and recession time in the field is required the accurate measurement and this can be costly and time consuming. winsrfr model is used for simulation furrow irrigation by zero inertia and kinematic wave engines. using this model, advance time, reaction time, infiltration depth, runoff depth and application eff...

an important issue in implementation of a gis system is preparation of data to be entered in gis. to produce spatial data for gis using photogrammetric techniques, conventional method is to apply photogrammetric and gis systems individually (off-line procedure). this approach is costly, time consuming and somehow unreliable due to the fact that 3d photogrammetric model is not available at the t...
