In this paper satellite wave propagation at Ku and Ka band is considered. The design and simulation of a typical satellite beacon receiver at Ka band is designed and simulated for the future works. Also rain attenuation prediction at Ku band using satellite signal beacon measurement and simulations for Iran Telecommunication Research Center (ITRC) are presented. The measurement setup consists o...

In this report we discuss plans to carry out a longitudinal measurement study of changes in service-level reachability in the global TCP/IP Internet. We overview our experimental design, considerations of network and remote site load, mechanisms used to control the measurement collection process, and network appropriate use and privacy issues, including our efforts to inform sites measured by t...

HYPOTHESIS For patients with primary hyperparathyroidism and patients with 2 localization studies showing the same single location of parathyroid disease, use of intraoperative parathyroid hormone (IOPTH) measurement does not significantly increase the success of minimally invasive parathyroidectomy. DESIGN Retrospective cohort study. SETTING Experience of 2 academic centers over 5 years (a...

The dispersion of the measurement of electromagnetic disturbance above 1 GHz is mainly affected by site imperfections (expressed by SVSWR). To evaluate the uncertainty in electromagnetic disturbance measurements at 1 18 GHz, we measured SVSWR and the field strength at 9 measurement site. From our result, the measured field strength at each measurement site was observed in the range of 2σ that d...

This paper focuses upon the visual aesthetic performance of web sites. It describes an experiment in which a site, designed at three controlled levels of visual ‘enrichment’, was evaluated on a number of measures by two subject groups. The measures used represent the two main facets of the Categorical-Motivation model of aesthetics, and included others specific to the performance of web sites. ...

Healthcare security professionals are facing new challenges as their responsibilities in a fast-changing environment are increasing. The level of healthcare professionalism, the author says, can be improved through the use of risk assessments, strategic planning and design, security safeguards, and security program measurement. In this article, he discusses the importance of a site survey--prov...

An important step in the design process for a web site is to determine which information is to be included and how the information should be organized on the web site’s pages. In this paper we describe ’SiteGuide’, a tool that automatically produces an information architecture for a web site that a user wants to create. SiteGuide takes as input URLs of web sites from the same domain as this tar...

As we see many websites have a hierarchical organization of content. This organization may be quite different from the organization expected by visitors to the website and sometime it is unclear where a specific document is located. There are many algorithms that automatically search pages in a website whose location is different from where visitors expect to find them. In the above case visito...

The starting point for this paper is a comparison undertaken by Romm and Wong (1997) between two data sets focusing on the strategy of organizational web site design. The first data set, comprising two case studies, originally documented by Jarvenpaa and Ives (1996), was based on the computer industry in the US. The second data set, comprising one case study, was based on a university in Austra...
