Tracking user interests over time is important for making accurate recommendations. However, the widely-used time-decay-based approach worsens the sparsity problem because it deemphasizes old item transactions. We introduce two ideas to solve the sparsity problem. First, we divide the users’ transactions into epochs i.e. time periods, and identify epochs that are dominated by interests similar ...

هدف اصلی از انجام این تحقیق ایجاد یک تست کامپیوتری پویای خواندن یا cdrt می باشد. تستی که در عین حال که ویژگی های سایکومتریک تست (پویایی و روائی) را دارا باشد بتواند مهارت خواندن دانشجویان را به صورت پویا (dynamic) ارزشیابی کند. ارزشیابی پویا(dynamic assessment) که ریشه در تئوری «منطقه تقریبی رشد» یا zpd ویگوتسکی دارد دو هدف اصلی که در ارزشیابی ایستا یا سنتی (static or non-dynamic)توجهی به آن نم...

This paper examines whether in the analysis of the impact of monetary policy, the exchange rate can play a role along with the interest rate as a transmission mechanism of monetary policy effects on economic variables or not? For this purpose, the general dynamic stochastic equilibrium models were used in the form of a New Keynesian small open macro-economy; accordingly, in this study, the Baye...

The objective of this paper is to evolve simple and effective methods for the optimal power flow (OPF) problem in thermal units, which are capable of obtaining optimal power generations for a large-scale system. In optimization, GA has some well-known advantages and disadvantages. The classical (derivative based) method is applied as economic dispatch problem with transmission capacity constrai...

The objective of this work is to develop a dynamic geographical information system (DGIS) applicable for the simulation of spatio-temporal phenomena. DGIS is designed and implemented as a dynamic raster GIS in a fully integrated systems strategy using theory of modelling and simulation, discrete event systems speciŽ cations, and knowledge-based simulation methodologies. The approach accommodate...
