Most atomic physics experiments are controlled by a digital pattern generator used to synchronize all equipment providing triggers and clocks. Recently, the availability of well-documented open-source development tools has lifted barriers using programmable systems on chip (PSoCs), making them convenient versatile tool for synthesizing patterns. Here, we take advantage these advancements in des...

The harmonic generation process in a harmonic cascade (HC) FEL is subject to noise degradation which is proportional to the square of the total harmonic order. In this paper, we study the shot noise evolution in the first-stage modulator and radiator of a HC FEL that produces the dominant noise contributions. We derive the effective input noise for a modulator operating in the low-gain regime, ...

Since delivery of thefirst vacuum-column magnetic-tape transport in 1953 and thefirst movable-head disk drive in 1957, tape and disk devices in many configurations have been the principal means for storage of the large volumes of data required by data processing systems. Magnetic drums and other device geometries have also been important system components, but to a lesser extent. Over the past ...

Static and dynamic balance can be influenced by many factors. However, there is limited evidence regarding the effects that shoe sole hardness may have on balance. The aim of our study was to investigate different sports shoes bare feet static in healthy female individuals. Seventeen participants were included study. All assessed with feet, hard-support soft-foam shoes. order assessment for eac...

The built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. The built up layer (BUL) is formed in second deformation zone near the tool-chip interface in the back of the chip. This parameter influences the tool life and machined surface quality. This BUL should not be confused with the built up edge (BUE). The deformation of the BUL in...

In recent years, direct Time-of-Flight techniques have been exploited with single-photon detectors to provide long distance ranges and high-frame rates measurements. Detectors based on Silicon Photon Multipliers commonly collect repetitive laser shots reconstruct a histogram of the TOF returning pulsed-laser photons, so discriminate between signal, background light, detector noise. Instead perf...

Abstract Negative ions are an important constituent of the spatial afterglow atmospheric pressure plasmas, where fundamental plasma-substrate interactions take place that vital for applications such as biomedicine, material synthesis, and ambient air treatment. In this work, we use laser-induced photodetachment to liberate electrons from negative in region plasma jet interacting with argon-oxyg...

The investigation aims at static examination and determination of differences for three age groups: under 13, 13–15 years old over 15, all practitioners the martial art karate do. This occured level main parameters, measured using FreeMed baropodometric platform Free Step software by Sensor Medica: plantar surface areas, location pressure center (C) inside support polygon, imbalances noticed Pm...

The effect of an electroless Ni-Cu-P coating on the fatigue behavior of quenched and tempered CK45 steel has been investigated. The fatigue tests under rotating bending conditions have been conducted in three different conditions of uncoated, as-deposited and shot peened prior to the coating deposition. The results indicate that plating of the base steel leads to a fatigue life reduction. The d...

plantar artery which had been severed, and was in a very weakened condition, though quite cheerful when spoken to encouragingly. In addition to rupture of the plantar artery, part of the lower portion of the articular area of the oscalsis had been shot away, together with the internal lateral ligament. The lost part, however, was not of such a nature as to cause any dislocation or disfigurement...
