Recently, there has been a large interest in the 3D modeling of real scenes using range data scanned by laser sensors. After the range scans from different viewpoints are acquired, an important step is the registration of these different scans in a common frame of reference. Considering that there often exist a great number of planes in real scenes, we present a range registration method based ...

The main objective of this research is to analyze the bifurcation phenomenon in Internet congestion model for Transmission Control Protocol (TCP) with Random Early Detection (RED). This problem can be divided to many categories considering different viewpoints. Different approaches of modeling (continuous and discrete models) and various system structures (control in end node or routers) are so...

This paper describes how the RM-ODP approach for system specification is applied to the description of the IT architectures of a large Swiss bank. The IT organization of UBS AG is defining several architectures based upon a business model which describes the main objectives of the bank considering the IT requirements. The semantics and the components of each architecture are explained using the...

Bioethics needs to include study of the social and historical context in which ethical meanings in medical encounters make sense. It needs to do this in order to remain relevant, vibrant, and aware of how it might unwittingly facilitate the agendas of others. As an illustration, this paper critiques some of the accepted meanings and purposes of the idea of the Therapeutic Misconception (TM) whi...

The paper analyses the reengineering concept as it comes from software engineering and management fields. We combine two viewpoints and apply them to solve a problem of reengineering of a distance study system, in general, and the unit of learning, in particular. We propose a framework for reengineering of unit of learning, based on general model of software reengineering, and present a case st...

Background: In the recent decades, worldwide attentions were increased in many countries for example North America and Europe to evaluate physician’s performance and become a necessity. The purpose of this study was to translate and determine the validity and reliability of the Persian version of the 360-degree assessment for anesthesiology residents. It consists of different d...

the aim of the research was to investigate the content analysis of physical education organization chiefs’ viewpoints on sport components from 1357 to 1388. 325 reports on physical education organization chiefs were gathered from ettela’at newspaper and were investigated by whole counting sampling. for content analysis, researcher-made coding sheet was used and the validity and reliability were...
