The pathloss exponent and the variance of the large-scale fading are two parameters that are of great importance when modeling or characterizing wireless propagation channels. The pathloss is typically modeled using a single-slope log-distance power law model, whereas the large-scale fading is modeled using a log-normal distribution. In practice, the received signal is affected by noise and it mig
This research was undertaken in an aerospace company, which manufactures aero engines and also offers contracts, under which it remains responsible for the maintenance of engines. These contracts allow the company to collect far more data about the in-service performance of their engines than was previously available. This paper aims at understanding what parts of this in-service information are a
To overcome the bottleneck of the one-way translation from VR (virtual reality) to CAD in VR-based CAD system, this paper proposes a Web-based VR-CAD system WVCD (Web-based virtual conceptual designer) to support both customers’ and design team members' involvement in the conceptual design and analysis activity over the Internet. It provides users with both parametric and freehand methods to creat
In order to stimulate benchmarking and comparisons between different municipal activities, the Swedish Association of Local Authorities and Regions (SALAR) and the Ministry of Finance in the year of 2007 initiated a voluntary nationwide Swedish benchmarking project (NBP) in order to develop new measures that capture the relationship between cost and quality. The ambition is that the new measures s
A number of techniques have been proposed to provide run- time performance guarantees while minimizing power consumption. One drawback of existing approaches is that they work only on a fixed set of components (or actuators) that must be specified at design time. If new components become available, these management systems must be redesigned and reimplemented. In this paper, we propose PTRADE, a n
There has been much work concerning the comparative analysis on English and German (e.g. Hawkins 1986), but there is an area still less studied. Diachronic comparative studies in these languages show a typologically unique diversity within a same language family. What is used as a key factor in this paper is alignment change.
Alignment can involve various linguistic features, but what various
