Abstract—Ultra-Wideband (UWB) technology is a low power and high data rate technology for applications like radar imaging, sensor data collection, position localization and medical imaging. In UWB systems, antennas plays a critical role as they are required to be compact and wideband with minimal pulse distortion. This paper present a small three-dimensional volcano smoke antenna, designed and opt

ad transport of dangerous goods is due to its inherent risk associated with a potential impact far higher than the small volumes might suggest, and has therefore been the target of numerous ITS-related initiatives. However, there are few indications of actual working ITS solutions for dangerous goods. In this paper we conduct an empirical investigation of past projects and research to analyze the

Gas phase polyethylene reactors are able to produce several different grades of polymer. Adapting to market conditions requires grade transitions, associated with costs in terms of raw material and temporary production of lower priced off-specification products. In this paper, both stationary production and dynamic grade transitions are optimized to maximize profit, i.e., economic process optimiza

Objective: To evaluate long-term oncological outcome and surgical quality of robotic radical hysterectomy for cervical cancer. Methods: Consecutive women with stage IA2 to IIA operated between March 2006 and May 2012 with a robotic radical hysterectomy and pelvic lymphadenectomy were prospectively followed up until five years after surgery or until death. Details regarding clinical results, recurr

A general mixed initial-boundary value problem for a non-local hyperbolic equation, relevant for the study of the propagation of transient electro-magnetic waves in flat slabs, consisting of dispersive stratified complex media, and excited by incident plane waves, is treated. Theorems regarding unique solvability and causality are presented and proved by a time domain method similar to the one use

Objective. Most methods for measurements of the regional cerebral blood flow are unable to provide absolute blood flow values. Until now interest has been focused on measurement of the gray matter blood flow, while the white matter blood flow has been rather neglected. The aim of the present project was to develop and evaluate an improved method for reliable tomographic measurements of absolute wh

The 2nd generation bioethanol will be produced from lignocellulose biomass including agricultural residues such as bagasse, straw, and stover, forest products residues and dedicated energy crops. The bioconversion of lignocellulose raw materials to ethanol requires microorganisms that are able (i) to ferment both hexose and pentose sugars present in lignocellulose and (ii) to tolerate and to remai
