the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
This paper presents a literature review discussing empirical as well as conceptual papers concerning the CTO – the Chief Technology Officer – his tasks, responsibilities and authority and his relations with other corporate functions.

Information System (IS) flexibility has been regarded as an important indicator of information technology success. This article provides a model of IS flexibility encompassing all stages of IS implementation and usage. The model considers the cognitive factors from IS staff and users as important leveraging IS flexibility with adaptation activities. A review of constructs extending from the int...
In this, paper we present a probabilistic approach to analysis and prediction of protein structure. We argue that this approach provides a flexible and convenient mechanism to perform general scientific data analysis in molecular biology. We apply our approach to an important problem in molecular biology-predicting the secondary structure of proteins-and obtain experimental results comparable t...
Based on the literature on decision support systems, we develop propositions about the appropriateness of knowledge management system (KMS) designs for different organizational knowledge processing challenges. An exploratory field experiment is conducted in the context of Internet-based online knowledge sharing services to provide empirical support for our propositions. The results of our exper...
Activity theory is a powerful theoretical instrument to untangle the " complications. " Based on activity theory, a comprehensive framework is proposed in Part I (Y. Xu, 2007) of this report to describe interactive information retrieval (IIR) behavior. A set of propositions is also proposed to describe the mechanisms governing users' cognitive activity and the interaction between users' cogniti...
Models of business processes are usually created and presented using some visual notation. In this way, one can express important activities, milestones, and actors of a process using interconnected graphical symbols. While it has been established for other types of models that their graphical layout is a factor in making sense of these, this aspect has not been investigated in the business pro...
To develop recommendations for the management of medium to high-dose (ie, >7.5 mg but ≤100 mg prednisone equivalent daily) systemic glucocorticoid (GC) therapy in rheumatic diseases. A multidisciplinary EULAR task force was formed, including rheumatic patients. After discussing the results of a general initial search on risks of GC therapy, each participant contributed 10 propositions on key cl...
