data envelopment analysis (dea) is a technique that uses all collected observations to measure performance. this method presents no data about how to operate on dmu. the present research attempted to study a unit with all its subunits, if the unit is efficient, it means that all its subunits are efficient too and if it is an inefficient, it shows clearly that which one of the subunits makes ine...

Recently, underwater wireless sensor network is one of the popular research topics to scientist. There are many novel methodologies to reach the goal of the effectiveness network performance such as cluster-based structure, in-network data aggregation, etc. In this paper, we assume the network is clustered by a specific clustering scheme. Then, we suggest a new geographicaldata-aggregation meth...

Big Data aims at the efficient processing of massive amounts of data. Performance modeling is often used to optimize performance of systems under development. Based on experiences from modeling Big Data solutions, we describe some problems in applying performance modeling and discuss potential solution approaches.

Two antagonistic models are used to model the training-performance relationship during an eight week cycling training, with a prediction of the performances in the last week of training. Results indicated different qualities of the model fits for the test data for both models. Mean differences between predicted and real performances were 2.39% for the Fitness-Fatigue-Model and 4.43% for the Per...

In this paper, we focus on the synthetic understanding of documents, specifically reading comprehension (RC). A current problem with RC is the need for a method of analyzing the RC system performance to realize further development. We propose a methodology for examining RC systems from multiple viewpoints. Our methodology consists of three steps: define a set of basic skills used for RC, manual...

This paper presents a survey of segmentation handwritten cursive word images into individual characters. It provides a comprehensive review of segmentation rates and descriptions of test data for the approaches discussed. Techniques that used to decide segmentation points describe in detail. Then the performances are compared in two categories based on number of words and existence of learning ...

This project aims at developing tools to extend the use of the MediaCycle software to live performances and installations. In particular, this requires real-time recording and analysis of media streams (e.g., video and audio). These tools are developed as patches for the Puredata (Pd) software [10] which is widely used by the artistic community. This project is a collaboration with the Belgian ...

data envelopment analysis (dea) was developed to help compare the relative performance of decision-making units. it is a non-parametric method for performing frontier analysis. it uses linear programming to estimate the efficiency of multiple decision-making units and it is commonly used in production, management and economics [3]. dea generates an efficiency score between 0 and 1 for each unit...

introduction: establishing improvement in every organization requires assessment of organizational performance, planning and goal-setting to improve the performance. despite remarkable progresses occurred in recent years on designing the frameworks and performance evaluation systems, many organizations still rely on traditional criteria. therefore, according to the importance of performance eva...
