A financial model has been developed that takes into account the impact of cost elements and unit costs on cargo transportation forms basis for calculating resulting performance indicators

using productivity index for investigating a firms’ performance makes it possible to evaluate efficiency of the production system and cost at the same time. in this study the total factor productivity (tfp) of several sugar cane varieties in imam khomeini cultivation and processing center in khuzestan province is compared. two hundred and forty eight farms are categorized on the basis of variet...

introduction: a large number of software programs have been used in dentistry for diagnosis and treatment planning to date. however, due to promotion of programming languages and developments in dental sciences, it is necessary to develop and update these softwares. use of softwares for treatment planning for removable partial dentures has been popular for some time and always new softwares hav...

Abstruct: Optimum frequency reuse patterns for roadside base station to vehicle communications in Intelligent VehicldHighway Systems (IVHS) are determined based on optimal delayhhroughput and packet erasure rates for BPSK transmission over narrowband dispersive Rician channel with IS1 and (Rayleigh-faded) co-channel interference. For fixed cluster size and fixed total system bandwidth, a reuse ...

Retrovirus-mediated gene transfer into hepatocytes in vivo results in long-term gene expression. Limitations include the need to remove two-thirds of the liver and the relatively low frequency of gene transfer. To increase gene transfer without surgical hepatectomy, mouse hepatocytes were transduced in vivo with a recombinant adenovirus that transiently expressed urokinase, resulting in high ra...

The technique of hierarchical matrices is used to construct a solution operator for a discrete elliptic boundary value problem. The solution operator can be determined once for all from a recursive domain decomposition structure. Then, given boundary values and a source term, the solution can be evaluated by applying the solution operator. The complete procedure yields all components of the sol...

We investigate the impact of self-interference on the performance of joint partial RAKE (PRAKE) receiver and adaptive modulation over both independent and identically distributed and independent but non-identically distributed Rayleigh fading channels in the presence of self-interference in terms of the average spectral efficiency as performance measures. Some selected results show the performa...

A 2-D version of PPM (Prediction by Partial Matching) coding is introduced simply by combining a 2-D template with the standard PPM coding scheme. A simple scheme for resolution reduction is given and the 2-D PPM scheme extended to resolution progressive coding by placing pixels in a lower resolution image layer. The resolution is increased by a factor of 2 in each step. The 2-D PPM coding is a...
