The purpose of the design and application of the ATMEGA8535 microcontroller system simulation circuit is minimize the damage of the practicum module, helping students improve their understanding of practicum goals through maximum frequency of practices. Every year damage the practicum module avr8535 increased. Based on the analysis, the damage of this module is mostly caused by the damage of the main component, namely the IC ATMEGA8535. This happen because a maximum of program downloading to the IC ATMEGA8535 is 1000 times and this ability can even be less if the operation procedure of the module is incorrect. This simulation software utilizes the facilities contained in the proteus software. The steps to make this simulation circuit are doing the needs analysis, designed the basic circuit, ouput circuit, input circuit, and ADC circuit. The test results show all units of the circuit can run according to the practicum module. This simulation circuit has been implemented in microcontroller practicum activities and interfacing as companion software. There was a decrease in module damage of 57.60% after the implementation of simulation circuit. With this simulation software programs that have been created can be loaded first into a simulations circuit, so they can extend the life time of the practicum module and can help lecturers in developing lecture material and maximize the understanding of learning for students through practical activities.

Background: Katigraha (lumbago)is the condition which is characterised by Stiffness and Pain. Due to Vitiation of Vata in the Katipradesh. About 80% of the industrial population and 60% of the general population experience low back pain at some point of their life time due to wrong postural habits and psychological factors. Basti chikitsa is mainly useful in disorders related to Vata Doshas. Matrabasti is a type of Sneha Basti which can be given in all seasons without any strict regimen of Diet. It has Brumhana and Vatashamaka in nature. And Madhur Dravya (Ashwagandha Taila) is one such combination to pacify the Vata in Katigraha. Objectives: To evaluate the efficacy of Madhur Dravya (Ashwagandha Taila) Matrabasti in Katigraha for relieving Pain and Stiffness. Settings and design: This was an open-labelled single arm interventional clinical study. Methods: Fifteen diagnosed case of katigraha were registered from the outpatient and inpatient department of Panchakarma and Madhur Dravya (Ashwagandha Taila) Matrabasti administered for 9 days. Statistical Analysis- The data were statistically analysed by using paired t test.

Electromagnetic Shielding Effectiveness

In the research, The electromagnetic interferences (EMI) have drastically increased and can disrupt and reduce the life time and the efficiency of devices. Therefore, the electromagnetic shielding problem is become the important issue. In the research, Ni wire and Cu wire (Floodlit Enterprise Co., Ltd.) were used to make the Ni conductive composite yarn and Cu conductive composite yarn via an electrical covering machine. And the Cu conductive composite yarn was fabricated to the woven fabrics with the plain weaving. The test results revealed that the EMSE of the W/K/W complex fabrics have stable EMSE than the W/W/W complex fabrics when the laminated at the same direction. The W/90W/W complex woven fabrics were shown the best EMSE of 46.25 dB, which the test frequency is 1800 MHz.

Point Of Departure

Start-transient testing of a hybrid (combined hydrostatic and hydrodynamic action) bearing supplied with air was completed, providing an indication of its performance while operating in a compressible fluid medium. The test start transients were modeled after Rocket Engine Transient Simulation Software (ROCETS) predictions for start-transient behavior of running speed ω(t) and bearing supply pressure Ps(t). The top test speed was 15 krpm. The ramp rate, supply pressure Ps values at 15 krpm, constant bearing unit load magnitude w0, and load orientation (load-on-recess LOR or load-on-land LOL) were varied. Five different load-case combinations were carried out (separately) for LOR and LOL load configurations with ramp rates varying from 2206 rpm/s to 8824 rpm/s. The target pressures at 15 krpm varied from 5.32 bars to 18.25 bars. The tested bearing dimensions were: L = D = 38.1 mm, and Cr =.0635 mm. Lift-off occurs due to the increase in Ps (ω dependent) and was defined as the point of departure towards the center of the bearing with increasing ω while the rotor remained 0.00254 mm (0.1 mils) above the bearing surface. This method is limited by the inability to accurately measure an established operating bearing clearance. Evaluation of the lift-off Ps versus applied unit load w0 supports the following conclusions: (1) Lift-off Ps is approximately a linear function of w0, (2) Changing the ramp rate while keeping constant the specified Ps at 15 krpm has no significant impact, (3) Lowering the limit Ps at 15 krpm may reduce the lift-off Ps value, and (4) The LOR start-transient cases required a higher lift-off speed and lift-off Ps values than the corresponding LOL start-transient cases.

With the fierce research on the space and terrestrial network, the satellite network as the main component has received increasing attention. Due to its special operating environment, there are temporary link failures caused by interference and permanent port failures caused by equipment problems. In this paper, we propose a new satellite network routing technology for fault recovery based on fault detection. Based on Bayesian decision, this technology judges the probability of each fault by a priori probability of the two faults to achieve the purpose of effectively distinguishing between two types of faults and locate faulty links and node ports. Then, corresponding to the previous two stages of the fault detection, different stages and different methods are updated for different types of fault. We also combine satellite network data from satellite simulation software to validate our study. The results show that the recovery strategy has good performance, and the effective resource utilization rate is improved significantly.

Heavy-equipment airdrops are mainly used to deliver relief supplies and heavy weapons. Given the heavy weight of the goods, the tension of the extraction and brake ropes of the parachute significantly affects the safety of the aircraft. On the basis of the measurement and installation characteristics of the parachute rope, this study designed the structure of a nondestructive pressure-type parachute rope tension sensor and set the location of the strain gauge patch using the ANSYS simulation software to obtain a high sensor sensitivity. The temperature error of the tension sensor is compensated, and the precision is improved using the LSSVM-PSO (Least Squares Support Vector Machine-Particle Swarm Optimization) algorithm. The developed tension sensor is applied to the extraction parachute test system to measure the traction of 2 and 8 m2 parachutes. Test results show that the maximum weight of the platform these two parachutes can draw and the effect of parachute opening can be calculated.

This article analyzes the current status of the lighting quality at the Escuela Técnica Superior de Ingeniería Aeronáutica y del Espacio (ETSIAE), the aerospace engineering faculty at the Universidad Politécnica de Madrid (UPM), and evaluates possible improvement actions based on the use of DIALux® lighting simulation software together with measured data. The results show rather low levels of measured illuminance on classroom desks and blackboards in one of the buildings comprising the faculty. The improvements proposed (a new coat of paint on the walls and replacement of luminaires) were simulated in four individual classrooms representing all rooms in two of the ETSIAE buildings (where the lower illuminance levels were measured). In order to study these improvements, the current situation of the four selected classrooms was simulated using DIALux® and fine-tuning attenuation of the luminaires to take into account their wear and tear. The correlation between the DIALux® simulation and the test results was analyzed with quite good results. The results clearly reveal a need to fully replace the classroom lighting systems in ETSIAE building A (the oldest building, dating back to 1955). According to the results from the selected classrooms, the average lighting over the desks can be greatly improved by using LED technology in order to meet UNE 12464-1 standard (that is, 500 lx, from an initial situation with much lower illuminance values: 129 lx to 295 lx). This article represents an innovative way to perform lighting improvement projects as real measured lighting data is used as initial input for the lighting simulations.
