Risk & return relationship in the portfolio of banks' common stocks nyse versus ISE
(European Journal of Scientific Research, 2007)
The main indicators of risk for a particular asset or a portfolio are the standard deviation which we define it as an indicator of total risk and the beta which we define it as an indicator of systematic (market) risk. In ...
Research on the middleware of grid GIS - distributed cooperative computing GIS software and its key technologies
(SPIE-INT SOC OPTICAL ENGINEERING, 2007)
This paper introduces the concept of grid computing and its characteristics. Basing on analyzing the characteristics of grid computing, we apply grid computing to GIS field to construct grid GIS, which is the application ...
Determining a continuous marker for sleep depth
(PERGAMON-ELSEVIER SCIENCE LTD, 2007)
Detection and quantification of sleep arousals is an important issue, as the frequent arousals are known to reduce the quality of sleep and cause daytime sleepiness. In typical sleep staging, electroencephalograph (EEG) ...
Frequency domain analysis of power system transients using Welch and Yule-Walker AR methods
(PERGAMON-ELSEVIER SCIENCE LTD, 2007)
In this study, power quality (PQ) signals are analyzed by using Welch (non-parametric) and autoregressive (parametric) spectral estimation methods. The parameters of the autoregressive (AR) model were estimated by using ...
Gene expression profile class prediction using linear Bayesian classifiers
(PERGAMON-ELSEVIER SCIENCE LTD, 2007)
Due to recent advances in DNA microarray technology, using gene expression profiles, diagnostic category of tissue samples can be predicted with high accuracy. In this study, we discuss shortcomings of some existing gene ...
Client's cache updating using idle time of clients in relational database management systems
(INST INFORMATION SCIENCE, 2007)
Although multi-tiered software development is taking the place in database application environments, client-server infrastructure has still been in use for years. Furthermore, both infrastructures still need to be improved ...
Distance education techniques to assist skills of tourist guides
(IEEE COMPUTER SOC, LEARNING TECHNOLOGY TASK FORCE, 2007)
This study is a presentation of the usage of distance education technologies in a bid to support face to face education of tourist guide candidates during the training tour. The laws require tourist guide candidates to ...
Obtaining Volterra Kernels from Neural Networks
(SPRINGER-VERLAG BERLIN, 2007)
Both neural networks (NN) and Volterra series (VS) are widely used in nonlinear dynamic system identification. In VS approach, the system is modeled using a set of kernel functions that correspond to different order ...
