A handover (HO) is an important procedure used to maintain connectivity in mobile networks. Nevertheless, it is not sufficient when a user equipment associates with a certain base station for a very short period. In this letter, we propose an estimated time-of-stay-based cell selection (ETCS) scheme to minimize the number of unnecessary HOs that adversely affect the performance of heterogeneous...

Taking the Landsat TM and ASTER images of Hanshiqiao wetland nature reserve in 1988, 1996 and 2004 as data source, based on the images interpretation by supervised classification, the land use changes during the period 1988 to 2004 were analyzed through land use dynamic degree. And then the driving forces of land use changes were analyzed based on natural and artificial factors. The results ind...

Based on the analysis of existing relevant systems on the basis of inadequate, after a detailed investigation and research, urban planning and management information system will be designed for three-tier structure system, under the LAN using C / S mode architecture. Related functions for the system designed in accordance with the requirements of the architecture design of the functional relati...

In this paper, prosody-based attitude recognition and its application to a spoken dialog system are proposed. Paralinguistic information plays a important role in the human communication. We aimed to recognize the user’s attitude by prosody, and apply it to a spoken dialog system as para-linguistic information. In order to find important features to recognize the attitude from automatically ext...

paper presents an intelligent decision support system (DSS) for facilitating the adoption of the most appropriate multicriteria analysis (MA) method in solving the information systems (IS) project evaluation and selection problem. A knowledge base consisting of IF-THEN production rules is developed for assisting with a systematic adoption of the most appropriate MA method through considering th...

This paper seeks to improve usability and semantics of complex decision support based on multiple criteria and data envelopment analysis using the profile distance method. We recognize the need of decision making practice for more intuitive and understandable decision support in complex and comprehensive settings by proposing three areas for improvement. We suggest a more meaningful indicator o...

Attempting to obtain a classifier or a model from datasets could be a cumbersome task, specifically, when using datasets of high dimensionality. The larger the amount of features the higher the complexity of the problem, and the larger the time that is expended in generating the outcome -the classifier or the model-. Feature selection has been proved as a good technique for choosing features th...

The Special Issue of the Journal of Information Technology Management (JITM) is publishing very selective papers on information management, technology in higher education, integrated systems, enterprise management, cultural thoughts, strategic contributions, management information systems, and cloud computing. We received numerous papers for this special issue but after an extensive pe...

A number of e-Processes (i.e. software processes for developing e-Commerce information systems) are available in industry. It is difficult to select the best suited e-Process for a case at hand. At the same time this selection is important because functionality and quality of any system under development will depend on the instantiated software process. The knowledge required for the selection ...
