a newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (uwb) applications. the two band notches of this coplanar waveguide (cpw) fed antenna are achieved by an m-shaped slot (mss) embedded in the radiating element and a c-shaped strip(css) close to ground plane, therefore two very narrow rejected properties in the wireless loc...

a variety of anthropometric and training characteristics have been identified as predictor variables for race performance in endurance and ultra-endurance athletes. anthropometric characteristics such as skin-fold thicknesses, body fat, circumferences and length of limbs, body mass, body height, and body mass index were bi-variately related to race performance in endurance athletes such as swim...

In [1] we uniquely introduced ultra exponential functions (uxpa) and denednext step of the serial binary operations: addition, multiplication and power.Also, we exhibited the topic of limit summability of real functions in [2,3]. Inthis paper, we study limit summability of the ultra exponential functions andprove some of their properties. Finally, we pose an unsolved problem aboutthem.

We humans tend to believe that the world has always existed in the form in which we know it. History is fine as an object of study, but we rarely make the effort to really situate ourselves in the past. If we ask most pulmonologists who have started or finished their training this century about the origins of inhaled treatment for obstructive lung disease, we might be surprised to find how litt...

One of the potential benefits of the UWB radio is its multipath resolution. The implications are multipath components which might not be resolved as distinct arrivals in more narrowband systems, may be separately identified in UWB systems. This paper explores some of the propagation characteristics associated with UWB signals, based on measured data.

There are several types of ultra wideband (UWB) radar systems which can be used with advantage for the purpose of detection and tracking of persons moving behind obstacles. The intention of this paper is to test in real conditions performance of an impulse UWB radar in comparison with an M-sequence UWB radar for the mentioned application. For that purpose a through-wall measurement with two per...
