In recent years, with the increasing interest in indoor wireless communications systems, the development of appropriate tools for modeling the propagation within an indoor environ‐ ment is becoming of utmost importance. A versatile technique for studying propagation in such a complex scenario is ray tracing [1-2]. Through this approach, a number of paths, stemming from the transmitter, are trac...

Despite the last decade’s research and new insights into humanmachine communication, much of today’s technology is too complicated to use, e.g., [6]. This is true for consumer electronics as well as household devices—much of the cutting-edge products do not fit in an every-day environment for every-day users. Current home automation solutions are for technophile users. The lack of intuitive or ...

We consider a random walk on R in a polynomially mixing random environment that is refreshed at each time step. We use a martingale approach to give a necessary and sufficient condition for the almost-sure functional central limit theorem to hold.

the perform type of the monopoly enterprises are diversified, which is caused due to combined action of multiple effects. The interactive performance between “gene type” and environment of the monopoly enterprises is one critical part. Accurate definition can assist to speed up expected benefits of the monopoly enterprises’ reform and construct the salary incentive mechanism of the monopoly ent...

This paper describes several paradigms for the directly manipulating a surface in computer graphics. The surface is considered as a collection of points in three-dimensional space which define a surface. These points may be the vertices of polygons, the control points of splines, and so on. Three paradigms are described and evaluated: direct grabbing of the surface at a single point and moving ...

It is unquestionably essential for students to gather their previous knowledge of specific subjects when they are about to learn new and more complex ones. The gaps left by the absence of welldefined learning prerequisites not only contribute to the increase in the learning difficulties, but also lead many students to fail in school. This situation gets even more serious when students are not a...

Conclusions: Ten times the EA2 of the working environment measurement concentrations, or ten times the B-value, obtained according to the Japanese working environment control system can be used to conservatively estimate the personal exposure concentrations in EU workplaces as well as in occupational exposure scenarios of the Regulation on Registration, Evaluation, Authorisation and Restriction...

Identification of multifactor gene-gene (G×G) and gene-environment (G×E) interactions underlying complex traits poses one of the great challenges to today's genetic study. Development of the generalized multifactor dimensionality reduction (GMDR) method provides a practicable solution to problems in detection of interactions. To exploit the opportunities brought by the availability of diverse d...
