The vast research conducted on nitrogen-vacancy (NV) centers in diamond recent years opened the door for a wide range of NV based applications. However, some properties center dynamics and energy levels remain unknown. In this work, we propose charge-conversion pulsed sequence scheme locating singlet manifold level, by multicolor excitation using tunable laser. We present two approaches readout...

Scene change detection is an essential process of frame rate up-conversion (FRUC). The performance FRUC highly dependents on the accuracy scene detection. This paper proposes a new scene-change method that uses analysis luminance level histograms for FRUC. histogram refers to statistical average value obtained from generated each region. Existing histogram-based methods calculate difference bet...

Analog-digital converters are inherently nonlinear. Conventional A/D conversion allows no real remedy afterwards. However, an alternative is to increase the available information by observing the transition instants, even with a conventional ADC. Performing the conversion with significant oversampling data points at threshold level crosses can be used. The values of these samples are precisely ...

This paper proposes the physical architecture of an electric power system with multiple homes. The notion of home is a unit of small-scale power system that includes local energy source, energy storage, load, power conversion circuits, and control systems. An entire power system consists of multiple homes that are interconnected via a distribution network and that are connected to the commercia...

This paper reports the study of both direct and indirect up-conversion sensitization luminescence phenomenon of the Tm ion’s G level in ZBLAN glass, oxyfluoride glass and pentaphosphate non-crystallite. We found, in the case of 4 indirect up-conversion sensitization, the up-conversion luminescence of Tm Yb La P O non-crystallite is enhanced 0.03 0.18 0.79 5 14 Ž . Ž . up to a level comparable t...

A new method for efficient, broadband sum and difference frequency generation of ultrafast pulses is demonstrated. The principles of the method follow from an analogy between frequency conversion and coherent optical excitation of a two-level system. For conversion of ultrafast pulses, the concepts of adiabatic conversion are developed further in order to account for dispersion and group veloci...

In this paper, a novel multi-target design methodology based on the concepts of transformational design, and its application to the interlaced-to-progressive scan conversion (IPSC) problem, are discussed. Starting from a single high-level behavioral specification in VHDL a direction detector used in IPSC adgorithms is mapped onto both a custom implementation and a programmable video signall pro...

a trial was conducted to evaluate the performance of broiler birds which supplemented with a commercial inactivated probiotic. four hundred and fifty day old broiler chickens were allocated into 3 treatments with 6 replicates each. each replicate was placed on clean wood shavings in floor pens receiving feed and water ad libitum. in treatment 1, feed was supplemented with 500 g/ton of a heat-in...

Background: Knowing the conversion risk factors of laparoscopic cholecystectomy to open surgery, helps the surgeon to plan for surgery accordingly. This study aimed to determine the risk factors for converting laparoscopic cholecystectomy to open surgery. Methods: In this analytical study, the case information of 1104 patients who underwent laparoscopic cholecystectomy in Shahid Beheshti Hospi...
