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 ... -
