How to select the best method for database applications, database independent platform or not?
(Journal of Applied Sciences, 2007)Software developers generally want to create software that could run with many different DBMSs (database independent platform). But, this idea sometimes may not be implemented to real world applications. The key point is ... -
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 ... -
Obtaining volterra kernels from neural networks
(IFMBE Proceedings, 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 ... -

A method for database independent application software development [Veri̇tabani baǧimsiz uygulama yazilimi geli̇ştii̇ rme yöntemi̇]
(Journal of the Faculty of Engineering and Architecture of Gazi University, 2007)Database independency can be defined as: a platform that a database includes only data in form of tables and indexes, and all other relations and processes about data are loaded in and managed by a data module located in ... -
Frequency domain analysis of power system transients using Welch and Yule-Walker AR methods
(Energy Conversion and Management, 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 ... -
Applying Mathematica and webMathematica to graph coloring
(Future Generation Computer Systems, 2007)This paper analyzes some graph issues by using the symbolic program Mathematica and its version for the Web, webMathematica. In particular, we consider the problem of graph coloring: the assignment of colors to the ... -
Face matrix: A quick search and indexing method for suspect recognition in police departments
(Information Technology Journal, 2007)This study presents an indexing and a quick sort method that could be used to find the possible matching guilty pictures from the police database by using a tracing software and eyewitness descriptions about the suspected ... -

(Journal of Euromarketing, 2007)This paper examines the impact of the three organizational success factors-customer focus, innovation, and personnel commitment-on the business performance of Turkish firms. A survey instrument was developed and administered ... -
Research on the middleware of grid GIS - Distributed cooperative computing GIS software and its key technologies
(Proceedings of SPIE - The International Society for 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
(Computers in Biology and Medicine, 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) ... -
Gene expression profile class prediction using linear Bayesian classifiers
(Computers in Biology and Medicine, 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 ... -
