Precision agriculture is becoming very important in improving food security. Unmanned Aerial Vehicles (UAVs) have higher possibilities in this way, improving real time data gathered with aerial sensors. Fuzzy techniques have proved to be highly effective in managing vagueness and ambiguity. The unmanned helicopters are highly valuable due to the level of maneuverability that they possess. We be...

Most plasma physics experiments that use ion beam heating need short bunches. To accommodate this requirement the RF system in the SIS is used to produce a single compressed ion bunch. Typical examples of such bunches were recorded in two beamtimes at the HHT experimental area in 2009 and are shown in Fig. 1. The bunch form is measured by a fast current transformer in the beamline. The bunch ha...

Laser-plasma interaction has been a widespread and popular field of research since the birth of the laser. It involves numerous interesting phenomena such as inertial confinement fusion; generation and acceleration of electron, positron, neutron, proton and ion particle beams; source of electro-magnetic radiation in the IR, visible, UV and x-ray range, just to mention some important application...

introduction breast cancer is one of the most common types of cancer among women.  early detection of breast cancer is the key to reducing the associated mortality rate. the presence of microcalcifications clusters (mccs) is one of the earliest signs of breast cancer. due to poor imaging contrast of mammograms and noise contamination, radiologists may overlook some diagnostic signs, specially t...

In this paper I examine some of the factors influencing technology development and attempt to explain whether CLIA '88 enhances the opportunities or exacerbates the problems for U.S.-based technology development. The viewpoint I express is concentrated on the clinical chemistry segment of the diagnostics arena.
