During the last years, the concept of input congestion and technical ineff-ciency in data envelopment analysis (DEA), have been investigated by manyresearchers. The motivation of this paper is to present models which obtain thedecreased output value due to input congestion and technical ineciency. More-over, we extend the models to estimate input congestion, technical ineciencyand output reduct...

Technology development and the fast changing market have resulted in the life cycle of high-tech products becoming shorter. Enterprises must therefore continuously conduct innovative research to meet customer demand and increase industrial competitiveness. Innovative product research and management have become the most important activities in enterprise survival and sustainability. This study i...

Fundamental and technical analyses are two common methods for predicting the future behavior of the stock. Fundamental analysis focuses on the economic forces of supply and demand which cause stock prices change. On the other hand, technical analysis examines historical data relating to changes in the price and trading volume by using graphs and indicators as a primary tool to predict future pr...

The aim of this paper is to test the validity and reliability of a Portuguese version of the Team Factors Inventory/TFI derived from the Creative Leadership Model. This inventory measures the propensity of a team towards creative leadership and consists of a paper and pen measure with 37 items on a Likert-type scale. The literature concerning creativity in organizational studies has focused mai...

In this paper we cluster and analyse temporal user behaviour in online communities. We adapt a simple unsupervised clustering algorithm to an evolutionary setting where we cluster users into prototypical behavioural roles based on features derived from their ego-centric reply-graphs. We then analyse changes in the role membership of the users over time, the change in role composition of forums ...

The present research aims to design strategic management model in technical and vocational training. The research has qualitative design and for data analysis and classification, thematic Analysis Method (Thematic Network) was applied. The statistical population of the study consisted of experts of the Iran Technical and Vocational Training Organization. The number of 13 participants were selec...

The importance rating of the technical skills and their related knowledge of industrial engineering and business management graduates are developed. A survey was conducted at the Faculty of Economics of the Budapest Tech to measure and evaluate 17 technical skills required by employers. The study utilized questionnaires to rate and rank these skills based on student assessment. The research was...

1 Intro In my 1988 SIGPLAN paper “Control-Flow Analysis in Scheme,” I promised to cover several items in more detail in a “forthcoming tech report.” The tech report has yet to happen. Most of the promised items have been covered in other papers (“The Semantics of Scheme Control-Flow Analysis” and “Data-Flow Analysis and Type Recovery in Scheme”). Useless-variable elimination, however, is still ...

The aim of this paper is to analyze total factor productivity (TFP) growth and its components in Asian countries applying Stochastic Frontier Analysis (SFA) to the time series data of 44 Asian countries from 2000 to 2010. Using Battese and Coelli approach, TFP is divided into technical efficiency change and technical change. TFP decomposition using SFA method for the years 1998 to 2007 indicate...

In [4], we have studied the statistical properties and mono-fractality of the power system time series, voltage magnitude (V), frequency (f), and phase angle (θ). The power system data was measured using three Phasor Measurement Units (PMUs) installed at Baylor University, Harris Substation, McDonald Observatory in the Texas Synchrophasor Network [1]. Our analysis of several data sets has shown...
