Abstract (sommario):

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.

Abstract (sommario):

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.

Abstract (sommario):

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.

Abstract (sommario):

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.

Abstract (sommario):

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.

Abstract (sommario):

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.

Abstract (sommario):

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.

Abstract (sommario):

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.

Abstract (sommario):

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.

Abstract (sommario):

Transmission Control Protocol (TCP) is the dominant transport protocol today and likely to be adopted in future high‐speed and optical networks. A number of literature works have been done to modify or tune the Additive Increase Multiplicative Decrease (AIMD) principle in TCP to enhance the network performance. In this work, to efficiently take advantage of the available high bandwidth from the high‐speed and optical infrastructures, we propose a Stratified TCP (STCP) employing parallel virtual transmission layers in high‐speed networks. In this technique, the AIMD principle of TCP is modified to make more aggressive and efficient probing of the available link bandwidth, which in turn increases the performance. Simulation results show that STCP offers a considerable improvement in performance when compared with other TCP variants such as the conventional TCP protocol and Layered TCP (LTCP).

Abstract (sommario):

In this study we conduct wind resource assessment to evaluate the annual energy production of a wind turbine. To estimate energy production of a wind turbine over a period of time, the power characteristics of the wind turbine are integrated with the probabilities of the wind speed expected at a chosen site. The first data set was obtained from a wind farm in Denmark. We propose several probability density functions to model the distribution of the wind speed. We use techniques from nonlinear regression analysis to model the power curve of a wind turbine. The best fit distribution model is assessed by performing numeric goodness–of–fit measures and graphical analyses. Johnson’s bounded (SB) distribution provides the best fit model with the smallest Kolmogorov–Smirnov (K-S) test statistic . 15. The four parameter logistic nonlinear regression (4PL) model is determined to provide the best fit to the power curve data, according to the Akaike Information Criterion (AIC) and the Bayesian Information Criterion (BIC). The estimated annual energy yield is compared to the actual production of the wind turbine. Our models underestimate the actual energy production by a 1 difference. In Chapter Six we conduct data processing, analyses and comparison of wind speed distributions using a data set obtained from a measuring wind mast mounted in Humansdorp, Eastern Cape. The expected annual energy production is estimated by using the certified power curve as provided by the manufacturer of the wind turbine under study. The commonly used Weibull distribution is determined to provide the best fit distribution model to our selected models. The annual energy yield is estimated at 7.33 GWh, with a capacity factor of 41.8 percent.

Abstract (sommario):

AbstractIn inland ports, where access is done navigating along an estuary, river or artificial canal, the operation may be strongly conditioned by the tide (in case it has enough wide run) or the water level in the river. The variations in water level imply restrictions on the draft of the vessels that can access such ports.Siport21 has been working for several years in ports of these characteristics, where there is no possibility to dredge the inland waterway. The alternative is to develop synchronization analysis tools, which allow identifying the “operational windows” and maximizing the draft of the vessels in transit operations. The result takes advantage of the tidal run by means of adequate planning, so that there is always enough underkeel clearance safety margin.Grounding risk estimation is elaborated applying Monte Carlo method. A failure (grounding) function is defined, considering the propagation of the tidal wave (water level and current), ship speed along the waterway, wind conditions, squat, and other variables. Probability distributions of all variables involved are considered, so that thousands of random navigation conditions can be simulated. This allows to estimate the failure probability.This methodology is applied to a practical case of a port that is carrying out actions to improve and optimize its operations. To do this, AIS data and tide data along the entire waterway, obtained from measurement sensors and a calibrated numerical prediction model, have been used.

Abstract (sommario):

AbstractUrban residents commonly spend a considerable proportion of their time indoors, and it is, therefore, important to pay particular attention to the characteristics of their home. During the time that humans remain indoors, the only bridge connecting them with the natural environment was through the views from their windows. Studies on the effect of these views have highlighted the restorative effects that nature views can provide, including feelings of calmness and relaxation. Likewise, such views can help better manage stress, anxiety and scape from loneliness, because they make a connection between indoor and outdoor spaces. At a time of lockdown and isolation following the COVID-19 pandemic, window views were for many the only option for contact with the natural environment, which provided significant positive effects. With the aim of assessing the benefits that views can bring to humans, we set out to study the role of views of nature from windows by analysing the GreenCOVID survey, conducted during the first wave of the COVID-19 pandemic in Spain, England and Ireland.

Abstract (sommario):

Rain impacts roadways such as wet pavement, standing water, decreased visibility, and wind gusts and can lead to hazardous driving conditions. This study investigates the use of high fidelity Doppler data at 1 km spatial and 2-minute temporal resolution in combination with commercial probe speed data on freeways. Segment-based space-mean speeds were used and drops in speeds during rainfall events of 5.5 mm/hour or greater over a one-month period on a section of four to six-lane interstate were assessed. Speed reductions were evaluated as a time series over a 1-hour window with the rain data. Three interpolation methods for estimating rainfall rates were tested and seven metrics were developed for the analysis. The study found sharp drops in speed of more than 40 mph occurred at estimated rainfall rates of 30 mm/hour or greater, but the drops did not become more severe beyond this threshold. The average time of first detected rainfall to impacting speeds was 17 minutes. The bilinear method detected the greatest number of events during the 1-month period, with the most conservative rate of predicted rainfall. The range of rainfall intensities were estimated between 7.5 to 106 mm/hour for the 39 events. This range was much greater than the heavy rainfall categorization at 16 mm/hour in previous studies reported in the literature. The bilinear interpolation method for Doppler data is recommended because it detected the greatest number of events and had the longest rain duration and lowest estimated maximum rainfall out of three methods tested, suggesting the method balanced awareness of the weather conditions around the roadway with isolated, localized rain intensities.

Abstract (sommario):

COVID-19 may have forever changed our world. Given the limited space and air circulation, potential infections on public transportation could be concerningly high. Accordingly, this study has two objectives: (1) to understand air circulation patterns inside the cabins of buses; and (2) to test the impact of different technologies in mitigating viruses from the air and on surfaces inside bus cabins. For the first objective, different devices, metrics and experiments (including colored smoke; videotaping; anemometers; pressure differentials; particle counts; and 3D numerical simulation models) were utilized and implemented to understand and quantify air circulation inside different buses, with different characteristics, and under different operating conditions (e.g. with windows open and shut). For the second objective, three different live prokaryotic viruses were utilized: Phi6, MS2 and T7. Various technologies (including positive pressure environment inside the cabin, HEPA filters with different MERV ratings, concentrated UV exposure with charged carbon filters in the HVAC systems, center point photocatalytic oxidation technology, ionization, and surface antiviral agents) were tested to evaluate the potential of mitigating COVID-19 infections via air and surfaces in public transportation. The effectiveness of these technologies on the three live viruses was tested in both the lab and in buses in the field. The results of the first objective experiments indicated the efficiency of HVAC system designs, where the speed of air spread was consistently much faster than the speed of air clearing. Hence, indicating the need for additional virus mitigation from the cabin. Results of the second objective experiments indicated that photocatalytic oxidation inserts and UVC lights were the most efficient in mitigating viruses from the air. On the other hand, positive pressure mitigated all viruses from surfaces; however, copper foil tape and fabrics with a high percentage of copper mitigated only the Phi6 virus from surfaces. High-temperature heating was also found to be highly effective in mitigating the different viruses from the vehicle cabin. Finally, limited exploratory experiments to test possible toxic by-products of photocatalytic oxidation and UVC lights inside the bus cabin did not detect any increase in levels of formaldehyde, ozone, or volatile organic compounds. Implementation of these findings in transit buses, in addition to the use of personal protective equipment, could be significantly valuable for protection of passengers and drivers on public transportation modes, possibly against all forms of air-borne viruses.

Testo completo

Abstract (sommario):

This evaluation assesses how well IDB's current mode of engagement meets the needs and expectations of countries that have relatively higher income levels and increasing access to diverse funding sources.For the purpose of this evaluation OVE selected 10 countries as case study countries using three objective indicators: (a) income level, (b) level of access to international financial markets, and (c) the weight of the country in IDB's lending portfolio. The countries, labeled higher middle income countries (HMICs) in this evaluation, are Argentina, Brazil, Chile, Colombia, Mexico, Panama, Peru, Trinidad and Tobago, Uruguay, and Venezuela. The evaluation finds that IDB remains a valued and trusted development partner in the vast majority of the HMIC case study countries. It is still financially competitive, even in countries with investment-grade sovereign risk ratings, and is particularly so during times of international turbulence. IDB's counterparts particularly value the following aspects of their cooperation with the Bank: the discipline IDB helps impart to project design and execution, along with capacity building related to project management; the opportunity that IDB provides to learn from other experiences in the Region; the seal of approval that IDB's project financing can help provide through its social, environmental, and fiduciary safeguards; and IDB's ability to facilitate medium-to long-term project continuity across political cycles. However, the evaluation also finds that several aspects require further consideration as IDB moves forward, regarding the usefulness of country strategies; engagement with subnational governments; streamlining of IDB's different private sector windows; fine-tuning of some lending instruments; speed of project preparation and implementation; knowledge creation and sharing; and the introduction of fee-based services. The evaluation provides five recommendations to help IDB strengthen its engagement with High-Middle Income Countries.

Abstract (sommario):

Snow2Rain investigated the impacts and perception of climate change in East Greenland through a holistic approach that includes natural science methods of time series analysis and statistical climatology on the one hand, and social science approaches of social anthropology on the other. In addition, this interdisciplinary approach was based in a transdisciplinary framework by involving the local people in Tasiilaq (East Greenland) and their knowledge. Based on the intention to study the effects of climate close to the everyday life of the locals, snow was chosen as one such interdisciplinary indicator of climate change. In addition, Greenland, as the study site of Snow2Rain, is a region in the Arctic and thus affected by Arctic amplification (implying a temperature increase of about three times the global average). With this in mind, Snow2Rain examined changes in snow characteristics in East Greenland and their underlying mechanisms, and placed these changes in the context of social and cultural as well as socioeconomic impacts for local people. From the main results of Snow2Rain, it can be concluded that (i) Arctic amplification is less pronounced compared to other regions in the Arctic and therefore climate change impacts (e.g., changes in snowpack, transition from snowfall to rain) are less pronounced and co-determined by precipitation changes. The strongest signals for the transition from snow to rain were found for the summer season. In addition, the most important climate change events currently discussed by locals in Tasiilaq are the storm winds known as piteraqs and icequakes (earthquakes triggered by calving glaciers). There is considerable interest in scientific information about meteorological and climate conditions as well as changes in the community of Tasiilaq, even though the topic of climate change is not the most pressing issue within the community. It also became clear that local knowledge holders from Tasiilaq hold relevant knowledge about past snow and environmental conditions (e.g. stories about snow conditions along dogsledding routes), but several challenges exist that make it a complex task to make this knowledge usable for climate scientists. To give a few examples of the existing knowledge, there is a lot of relevant knowledge about changes in wind direction and wind speed, and particularly a lot of memories exist in relation to extreme wind events (piteraqs and other storm winds). Overall, the perception of climate change in Greenland is different than in Europe (the recent signing of the Paris Agreement seems to be a clear reflection of this). People from Tasiilaq region are very sensitive in observing changes of their environment including the climate. Snow is only one of those changes observed (wind/storms and earthquakes are currently widely discussed by the locals). However, they speculate much less about future changes and are cautious about the human influence on climate change.
