The study involves segmentation of the image using the three segmentation modules of three software namely ERDAS Imagine, ENVI and eCognition to extract building features. The best parameters for segmenting buildings have been established. New method of evaluation has been presented for evaluating segmentation quality. The results of three segmentation modules are assessed using the proposed ev...

In this research, a new method for market-product strategic planning is presented. In this method, an expert system is designed on the basis of identifying important factors that are effective in a firm and analyzing the logical relations between them. The objective is to develop a decision support system (DSS) for helping managers to make strategic decisions. DDS can serve as suitable replacem...

To formulate a single-leg seat inventory control problem in an airline ticket sales system, the concept and techniques of revenue management are applied in this research. In this model, it is assumed the cabin capacity is stochastic and hence its exact size cannot be forecasted in advance, at the time of planning. There are two groups of early-reserving and late-purchasing customers demanding t...

In this paper, we propose the knowledgeable envi. ronment as a framework for integrated systems for human-machine co-existing space. In the knowledgeable environment, integration is achieved as knowledge-level communication and cooperation. We abstract all machines as information agents whose roles and communication are understandable for people. Ontology is here used as explicit representation...

In this paper, estimation and tracking of the propagation delays, also known as code acquisition and tracking, in an asynchronous DS-CDMA system are considered. Of special interest is the performance in a near-far environment and the proposed estimator is shown to be near-far resistant. The suggested technique is subspace based and relies on recursively tracking the signal subspace, followed by...

Performance orientation in the development process of parallel software is motivated by outlining the misconception of current approaches where performance activies come in at the very end of the development mainly in terms of measurement or monitoring after the implementation phase At that time major part of the development work is already done and performance pitfalls are very hard to repair ...
