Background & Aim: One of the most important and useful models for assessing hospital performance is the Pabon Lasso Model, a graphical model that determines the relative performance of hospitals using three indicators: 1. Bed Occupancy Rate (BOR); 2. Bed turnover (BTO); 3 Average Length of Stay (ALS). The aim of this research is to investigate the performance of the hospitals affiliated with Te...

the estimation of velocity distribution plays a major role in the hydrodynamics of vegetated streams or rivers of extensive natural floodplains. the velocity profile in vegetated channels can be divided into three zones: uniform zone which is close to bed with uniform velocity distribution, logarithmic zone which involves the main channel with no vegetive cover and the transition zone that is a...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

The development of yielded or failure zone due to an engineering construction is a subject of study in different disciplines. In Petroleum engineering, depletion from and injection of gas into a porous rock can cause development of a yield zone around the reservoir. Studying this phenomenon requires elasto-plastic analysis of geomaterial, in this case the porous rocks. In this study, which is a...

 Estimating discharge and velocity in natural channels and flood plains for inflexible vegetative cover is important. In such waterways, velocity profile can be divided into three zones: uniform zone which is close to bed with uniform velocity distribution, logarithmic zone which involves the main channel without vegetative cover and the middle zone (transition zone) that is affected by the mom...

Pedestrians are the most vulnerable road users. For evaluating and modifying pedestrian safety in unsignalized crosswalks,the first important issue is to identify and explore factors affecting the interaction behavior of pedestrians andvehicles in conflict areas. By analyzing those factors and determining how they affect road user's behavior, we canrepresent the plans and proc...

An excavation damage zone (EDZ) can be defined as a rock zone where the rock properties and conditions have been changed due to the processes related to an excavation. This zone affects the behavior of rock mass surrounding the construction that reduces the stability and safety factor and increase probability of failure of the structure. This paper presents an approach to build a model for the ...

در میدان نفتی مارون، جنوب غرب اهواز، سازند آسماری ( الیگوسن - میوسن ) غالبا متشکل از سنگهای کرتاسه همراه با میان لایههایی از شیل، ماسه سنگ، آهک ماسه ایی و آهک رسی است که به صورت پیوسته روی شیلهای سازند پابده و با پیوستگی در زیر نهشتههای سازند گچساران قراردارد. فونایی نسبتا متنوع شامل فرمهای مختلف فرامینیفرهای بنتونیک و پلانکتونیک در نهشته های سازند آسماری در چاه 312 میدان نفتی مارون شناسایی شده...
