Agustin Anarwati, Iman Setiono, today human life is very rapidly developing, one of them in the field of technology as time advances. This requires the creation of ideas to make a variety of equipment that is more practical and more reliable in meeting needs. In the industrial world today, most equipment uses PLC as a controller for various existing equipment, while the Human Machine Interface (HMI) is used to simplify monitoring existing equipment. In the automotive world, the power windows system is part of the body's electrical circuit which aims to make it easier for motorists to operate car windows. The driver can adjust the work of the power windows through a switch. When the driver presses the switch then the motor power window will rotate and will make the window work both open and close. The type of motor used in the power window system is a DC motor. One of the features of this DC motor is its speed can be controlled easily. In this case, I tried to make the design of the monitoring device setting the DC power speed of the windows power using PLC and HMI as monitors and controllers for operating the DC power windows rotating speed to make it easier, the speed can be adjusted through the output voltage from the PLC to the driver, starting from 0 VDC up to 5 VDC. if the voltage is 5 VDC then the motor will rotate with a maximum speed of 100%, whereas if given a 2.5 VDC input, the motor speed will be half of the 5 VDC rotational speed.

We have developed an experimental setup of corn crusher of shock-reflective action. The experimental data on the impact of the loading windows location of corn crusher of shock-reflective effect on its activity were obtained. Their analyses were carried out and we identified the optimal location of the loading window, from the point of view of the of energy consumption reduction of grain refinement process. The authors studied the influence of feed delivery through the lower, upper and both loading windows simultaneously. According to the results of the experiments, we constructed graphs of energy consumption change, depending on the capacity of the crusher, during the loading the crushed feed through the top, bottom and both windows. As a result of this work it was founded that: the lowest cost crusher throughput 90 kg per hour are observed, while loading the feed through both windows; increasing the capacity over 90 kg per hour implies a sharp increase in power consumption, when applying the feed through both windows, and minimal consumption - when filing through the upper window; minimum energy fall is when feeding the feed through the top of window and hitting speed of n=2900 ... 5100 min-1. Thus revealed, that in order to reduce the energy consumption for a finished product, we must conduct further studies at loading the feed through the top window, and the rotor speed must be within n=2900 ... 5100 min-1.

Texto completo da fonteResumo:
Over the last 20 years, the rapid development of high-speed Chinese trains has provided valuable guidelines to countries and companies eager to develop their complex product and system (CoPS) sectors. CoPS refers to the high cost and technology-intensive systems, networks, infrastructure and engineering constructs, and services. Although established studies highlight the importance of CoPS to the economy and development of a country, especially those that have yet to develop high-speed rail, scholars have not paid much attention to investigating the catch-up of CoPS industries from the windows of opportunity perspective. We aimed to fill in this research gap by analyzing the successful catch-up of Chinese high-speed trains. Based on a longitudinal case study of this industry, we analyzed and detailed the mechanisms of the catch-up process of a typical CoPS sector and its development. Our results enrich the literature of the catch-up process, CoPS, and the studies of windows of opportunity. In particular, we show that the windows of opportunity that emerge in the catch-up process of CoPS have the characteristics of endogeneity, asymmetry, and relevance. Moreover, our study further indicates that the endogenous windows of opportunity regarding policy result in the development of later windows of technology and demand. We also find that the technology’s windows of opportunity consist of the window to broaden the technology width and the window to deepen the technology depth of latecomers. In addition to theoretical contributions, our findings can help policymakers of latecomer countries better formulate CoPS industrial policies, followed by a gradual progress in successfully catch-up with the leading countries.

The article describes a new bench for testing the reliability of passenger car windows and doors. The bench can be used in various industries, mainly in transport engineering, as well as in the construction industry. This bench is functionally designed to test the entire product (windows or doors), as well as to determine the service life of individual mechanisms of this product. In contrast to the known analogs, the new bench for testing the reliability of windows and doors allows testing under the influence of variable aerodynamic pressure arising from the operation of windows and doors on moving objects, for example on high-speed transport. Specially developed test method is proposed on this bench, which allows simulating alternating aerodynamic effects on windows and doors that occur when a train passes tunnels or when trains in opposite directions diverge at high speeds. Thanks to this, bench tests can serve as an actual addition to the existing methods of testing windows and doors of modern high-speed rolling stock.

Texto completo da fonteResumo:
Abstract We study the effect of sampling windows on derived shock and associated energetic storm particle (ESP) properties in 296 fast-forward interplanetary shocks using Advanced Composition Explorer measurements at 1 au between 1998 February and 2013 August. We vary the time windows from 2 minutes to 20 minutes for the shock properties and from 2 minutes to 540 minutes for ESP properties. Variability is quantified by the median absolute deviation statistic. We find that the magnetic, density, and temperature compression ratios vary from their median values by 17.03%, 20.05%, and 25.91%, respectively; shock speed by 16.26%; speed jump by 45.46%; Alfvénic Mach number by 31.53%; and shock obliquity by 24.25%. Spectral indices in the 2 minute–540 minute windows downstream of the shock vary from the median value of 1.79 by 26.05% and by 30.53% from the 1.70 median value upstream of the shock. Similarity of ESP spectral indices upstream and downstream of the shock suggest that these ESP populations are likely locally accelerated at the shock. Furthermore, we find that for a moving sampling window around the shock, values for the density ratio hold for ∼10 minutes; the magnetic ratio and shock speed jump hold for ∼30 minutes and ∼60 minutes, respectively. Fixing the upstream window to 2 minutes and moving only in the downstream direction, the density ratio holds for ∼60 minutes downstream, magnetic ratio holds for ∼30 minutes, and the shock speed jump holds for ∼110 minutes. Beyond these time windows, derived shock properties are no longer representative of shock properties. These results provide constraints for modeling and forecasting efforts of shock and ESP-associated properties.

In this paper, k-Omega turbulence model is applied in the numerical simulation of the transit bus, several typical working conditions of the transit bus with windows open at a speed of 10m/s are investigated, and a custom function Q is introduced to characterize the amount of ventilation of each window. The results show that, when the transit bus travels with windows open, the air always flows into the carriage through the middle and rear side windows of the transit bus, and circulates in the carriage and then flows out of the carriage through the front side window. When the bus travels with sunroofs open in leeward mode and side windows open, the amount of ventilation is the maximum. This working condition is the best one when taking both drag coefficient and the amount of ventilation.

Fluctuation-enhanced sensing (FES) comprises the analysis of the stochastic component of the sensor signal and the utilization of the microscopic dynamics of the interaction between the agent and the sensor. We study the relationship between the measurement time window and the statistical error of the measurement data in the simplest case, when the output is the mean-square value of the stochastic signal. This situation is relevant at any practical case when the time window is finite, for example, when a sampling of the output of a fluctuation-enhanced array takes place; or a single sensor's activation (temperature, etc.) is stepped up; or a single sensor's output is monitored by sampling subsequently in different frequency windows. Our study provides a lower limit of the relative error versus data window size with different types of power density spectra: white noise, 1/f(flicker, pink) noise, and 1/f2 (red) noise spectra.

External wind is one of the major factors that influence the spread of fire along building exterior facade in high-rise buildings. Fire simulation experiments are conducted .First, under two circumstances of low-speed and high-speed side-blown wind, observing barrier of window spill plume along building exterior facade under different dimensions of windows, windowsill walls and balconies. Then the correlation between smoke temperature near the exterior facade and dimensions of window, windowsill wall and balcony is obtained by numerical fitting and dimensional analyses. The correlation indicates that, on low-speed side-blown wind, spill plume spreading diagonal up downwind, balcony width plays a leading barrier; on high-speed side-blown wind, spill plume horizontal spreading downwind, balcony extension plays a leading barrier.

"Higher Playing Times Accumulated Across Entire Games and Prior to Intense Passages Reduce the Peak Demands Reached by Elite, Junior, Male Basketball Players." American Journal of Men's Health 15, no. 5 (2021): 155798832110543. http://dx.doi.org/10.1177/15579883211054353.
Texto completo da fonteResumo:
The aim of this study was to analyze the effects of different factors on the external peak demands (PD) encountered by elite, junior, male basketball players in games, including the (1) total playing time during games and (2) playing time accumulated directly prior to each PD episode. Workload variables included the PD for total distance, distance covered in different intensity zones, accelerations >2 m·s-2 (ACC), decelerations <-2 m·s-2 (DEC), and PlayerLoad. PD were calculated across different sample durations for each variable. Linear mixed models were used to identify differences in PD between groups based on playing times. PD for total distance (5-min window), high-speed running (>18 km·h-1) distance (2-min window), and ACC (30-s, 45-s, 1-min, 2-min, and 5-min windows) were significantly ( p < .05) higher for players who completed lower total playing times (16.6 ± 2.4 min) than players who completed higher total playing times (25.0 ± 3.4 min). The PD for total distance (30-s, 45-s, 1-min, and 2-min windows), high-speed running distance (30-s and 5-min windows), and PlayerLoad (1-min and 2-min windows) were significantly ( p < .05) higher for players who accumulated lower playing times before each PD episode than players who accumulated higher playing times before each PD episode. Players who undertake less playing time overall and prior to each PD episode can reach higher peak external loads aggregated across varied time windows. These findings can inform tactical coaching decisions during games for high external loads to be accomplished during important passages of play.
