In this paper, a hybrid of Bat-Inspired Algorithm (BA) and Genetic Algorithm (GA) is proposed to solve N-queens problem. The proposed algorithm executes the behavior of microbats with changing pulse rates of emissions and loudness to final all the possible solutions in the initialization and moving phases. This dataset applied two metaheuristic algorithms (BA and GA) and the hybrid to solve N-queens problem by finding all the possible solutions in the instance with the input sizes of area 8*8,...

This paper describes the initial findings of research work to assess the impact of thermal conditions on the human capacity to do work. Heart rate is considered as a lead indicator of human energy consumption. A laboratory was set up where human volunteers performed standard work routines under controlled conditions. The heart rate of the volunteers was constantly monitored while the temperatures of the laboratory were varied between 5 degrees to 40 degrees centigrade. Data analysis from the...

This paper presents and evaluates some methods to improve the accuracy of systolic blood pressure measurements based on pulse waveform. A set of measurement was carried out with elderly cardiac surgery patients. The experiments comprised two to five measurements per patient, each including a one-minute follow-up, after which the cuff was slowly inflated over the systolic blood pressure. Systolic pressure errors were defined and correlations with other specific values, like pressure rise time,...

Steady-state power conversion applications have benefited from numerous packaging and cooling improvements, and there has been a push to apply the same techniques to pulsed power electronic systems and devices. However, the unique aspects of pulsed systems create a trade-off between high package thermal capacity for mitigating rapid temperature rise and low thermal resistance for rapid heat rejection. This report details a numerical study of several electronics packages with varying levels of...

The U. S. Army Research Lab (ARL) is investigating the capabilities of high energy density capacitors at narrow pulse widths from two different manufacturers for high current pulsed power applications. Breakthroughs in this technology would allow smaller capacitor storage to be possible while retaining the same capabilities. The discharge pulse widths of the test shots were between thirteen and fourteen microseconds. These pulse widths were taken from the full wave half maximum pulse width...

The Phase I program explored the generation of submicrosecond wide CO2 laser pulsewidths using a completely sealed-off, non-recirculating pulsed discharge gain medium. Two sealed-off devices with nominal gain volumes of 1.5 mL and 35 mL were utilized in the Phase I program to generate pulses as short as several microseconds at atmospheric pressure and as long as 10 to 20 microseconds at pressures in the 60 to 100 torr region. Sealed-off PRF's from 50 to 500 Hz were used and single-fill...

Electrocardiograms of four monkeys were recorded during exposure of the animals to air slowly heated 5 -8C above room level. Neither rectal nor skin temperature was affected. Deceleration of the heart and increase in T-wave amplitude under these conditions are noteworthy phenomena. As a control, EKG records for two of the monkeys were similarly recorded during exposure to slowly cooling air. Rectal temperature showed a very small change. Heart rate and respiration rate increased and T-wave...

A comparison of the respiration of Macaca mulatta restrained with strait jackets or injected intramuscularly with 1 mg/kg of phencyclidine hydrochloride revealed that the minute volume of the strait-jacketed animals was about 3 times that of relatively unrestrained animals when measurements were made 10, 20, and 30 minutes after treatment. The values obtained from the drug- treated animals were about 60% of those predicted by Guyton (3), and those obtained from strait-jacketed monkeys were...

Camera-based measurement of the blood volume pulse via non-contact, imaging photoplethysmography is a very popular approach for measuring pulse rate using a remote imaging sensor. Comparatively less attention has been paid to the usefulness of the method for measuring features of pulse rate variability, and even less focus has been put on the accuracy of any cardiac activity feature that can be achieved at long imager-to-subject distances. In this study, video was recorded from 19 participants,...

Frozen Wave Hertzian generators have been built which can produce multikilowatt RF pulses in the megahertz frequency range with repetition rates of 10's of kilohertz. These generators do not have a damped sinusoidal output; they generate a discrete, controllable number of rectangular half cycles. The output waveform can be discretely changed from one half-cycle to the next. At the higher frequencies, discontinuities in the switch and dispersion in the cables round the edges of the rectangular...

A compact 1 MV Long Pulse Generator, developed for high power microwave application of electron beam sources, is described. Such applications require voltage pulse flat-top with low ripple (+- 1 percent) and low droop (- 2 percent). For the present application variable pulse widths of 0.1 to 10 microsecond into a fixed load (200 to 1 k omega) up to 500 kV, and 0.1 to 1 microsecond for voltage above 500 kV and up to 1 MV were required. This pulse generator is presently in operation in the new...

Many advanced electronic technologies and devices for the 1980's are based on sophisticated compound single crystals, i.e. ceramic oxides and compound semiconductors. Space processing of these electronic crystals with maximum perfection, purity, and size is suggested. No ecomonic or technical justification was found for the growth of silicon single crystals for solid state electronic devices in space.

A method of performing ultrasonic stir welding uses a welding head assembly to include a plate and a rod passing through the plate. The rod is rotatable about a longitudinal axis thereof. In the method, the rod is rotated about its longitudinal axis during a welding operation. During the welding operation, a series of on-off ultrasonic pulses are applied to the rod such that they propagate parallel to the rod's longitudinal axis. At least a pulse rate associated with the on-off ultrasonic...

The relative pulse-working-capacity 170 PWC(170 rel) is thought to represent the maximum workload which a person can achieve with constant oxygen-uptake. The general mean of about 3 Watt/kg body weight depends on gender and fitness and to a low degree on age. With allowing all kinds of military tasks for women in the german forces it is likely that only women out of the upper regions of the standard deviation of that special group will be chosen for demanding military tasks.

The surprising sensitivity of ignitors was encountered on RACE, a compact torus device. Its capacitor bank has both the common reverse-crowbar circuit and an unusual forward-crowbar circuit that made this investigation necessary. The ignitors were fired with high-capacitance coaxial-cable pulse transformers. When the bank fired, because of negative bank charge, forward-crowbar ignitrons saw both positive anode voltage and a positive pulse to their ignitors coupled through pulse transformer...

It is also combined with the RBackprop algorithm, which computes the product of the matrix of second derivatives (Hessian) with an arbitrary vector. The RBackprop method allows us to avoid computationally expensive, direct line searches. In addition, it can be utilized in the new, 'predictive' updating...

There was found a transient initial decrease in oxygen uptake correlated with the...
