BACKGROUND Road traffic Injuries (RTIs) as a health problem imposes governments to implement different interventions. Target achievement in this issue required effective and efficient measures. Efficiency evaluation of traffic police as one of the responsible administrators is necessary for resource management. Therefore, this study conducted to measure Iran's rural traffic police efficiency. ...
data envelopment analysis (dea) is a method for measuring the relative efficiencies of a set of decision-making units (dmus) that use multiple inputs to produce multiple outputs. in this paper, we study the measurement of dmu performances in dea in situations where input and/or output values are given as imprecise data. by imprecise data we mean situations where we only know that the actual val...
the aim of the present study was to evaluate the efficiency of the computer and internet training course from the viewpoint of dental students of kermanshah university of medical sciences in 2014. in this descriptive survey, the study sample included 39 dental students who entered university in 2011 and 2012. the required data were collected through a reliable and valid questionnaire using cens...
مقدمه : سرطان سینه از جمله شایعترین بدخیمی ها در زنان ایرانی می باشد که میزان بروز آن 09/17% در هر 100 هزار زن می باشد. میزان بقای 5 ساله این بدخیمی در حدود 75% گزارش شده است. سرطان پستان شایعترین علت مرگ در زنان پس از سرطان ریه بوده و شایعترین محل درگیری آن در ربع فوقانی-خارجی سینه می باشد. مبتلایان به سرطان سینه به دلیل مصرف داروهای مختلف از جمله مهارکننده های آروماتاز در معرض ابتلا به کاهش چ...
abstract this study scrutinized the interaction between linguistic and strategic variables in reading comprehension test performance of iranian efl learners. to this end, the interaction among the participants’ reading comprehension test performance, use of test-taking strategies, and level of language proficiency was analyzed. the participants comprised 286 students who answered a reading comp...
The present study is an attempt toward improving the performance of members of supply chain. Improvement of two-stage supply chains is three cases. Inefficients suppliers are improved or inefficient manufactures are improved or both of them are improved. First, New sub-perfect supply chain production possibility set is obtained with efficiency score of α for inefficient suppliers and only all D...
Data holders, such as statistical institutions and financial organizations, have a very serious and demanding task when producing data for official and public use. It’s about controlling the risk of identity disclosure and protecting sensitive information when they communicate data-sets among themselves, to governmental agencies and to the public. One of the techniques applied is that of micro-...
We present a question answering system (CASIA) over Linked Data (DBpedia), which focuses on construct a bridge between the users and the Linked Data. Based on the Linked Data consisting of subject-property-object (SPO) triples, each natural language question firstly is transformed into a triple-based representation (Query Triple). Then, the corresponding resources in DBpedia, including class, e...
Units of a good are produced at some symmetric cost. A mechanism elicits agents’ willingness to pay for one unit of the good, allocates some goods to some agents, and covers the cost by charging those agents. We introduce the generalized average cost mechanism (GAC) for arbitrary symmetric cost functions. GAC is the only Pareto selection among group strategyproof mechanisms that treat equal age...
The AllDifferent constraint is a crucial component of any constraint toolkit, language or solver, since it is very widely used in a variety of constraint models. The literature contains many different versions of this constraint, which trade strength of inference against computational cost. In this paper, we focus on the highest strength of inference (enforcing a property known as generalised a...
