The object of research is the process of unloading bulk crop products from the bodies of dump trucks, the subject of the study is the dependence of the energy consumption of unloading on the properties of products when exposed to vibration. This dependence is understood as a change in the properties of bulk products, such as internal friction and the angle of repose, in the direction of decreasing, providing a decrease in the angle of lift of the body. One of the most problematic areas is the lack of objective information on the dependence of the required lifting angles of the dump truck body when unloading fine-grained crop products when exposed to vibrations. There is also insufficient information on the dependence of these angles on vibration frequency for each of the products. In the course of the study, an experimental method was used to determine the angles of natural bevel for different crops without and under the influence of vibrations of different frequencies on the reference area. The proposed development makes it possible to quantitatively assess the degree of influence of vibrations, their frequencies and time of impact on the frictional properties of bulk crop products. The degree of reduction of internal friction in these products and the maximum angles of lifting the body required for its unloading were experimentally determined, and numerical data were obtained on their reduction under the influence of vibrations. The results obtained allow to consider it an effective tool for obtaining objective information about the effect of vibrations on the characteristics of internal friction of bulk crop products. This made it possible to determine the degree of influence of the lift angle of the dump truck body during unloading and to reduce energy costs. In contrast to the existing ones, the proposed development makes it possible to differentiate these angles depending on the frequency and time of exposure to vibration, as well as on a specific product. Certain parameters make it possible to regulate them to achieve minimum energy consumption.

The body of literature on climate change impacts on building energy consumption is rising, driven by the urgency to implement adaptation measures. Nevertheless, the multitude of prediction methodologies, future scenarios, as well as climate zones investigated, results in a wide range of expected changes. For these reasons, the present review aims to map climate change impacts on building energy consumption from a quantitative perspective and to identify potential relationships between energy variation and a series of variables that could affect them, including heating and cooling degree-days (HDDs and CDDs), reference period, future time slices and IPCC emission scenarios, by means of statistical techniques. In addition, an overview of the main characteristics of the studies related to locations investigated, building types and methodological approaches are given. To sum up, global warming leads to: (i) decrease in heating consumptions; (ii) increase in cooling consumption; (iii) growth in total consumptions, with notable differences between climate zones. No strong correlation between the parameters was found, although a moderate linear correlation was identified between heating variation and HDDs, and total variation and HDDs. The great variability of the collected data demonstrates the importance of increasing specific impact studies, required to identify appropriate adaptation strategies.

The Impact

Background. The human foot contains one of the most variable structures of the body, which is the medial longitudinal arch. Decrease in the height of this arch results in a flat foot. Although there is some evidence regarding the influence of flat foot on gait performance of flat-footed individuals, there is no strong evidence to support the theory that being flat-footed has an effect on energy consumption. Therefore, the aim of this study was to find the relationship between flat foot and energy consumption. Method. Two groups of normal and flat-footed participants were recruited in this research project. They were selected from the staff and students of Isfahan University of Medical Sciences. The foot indexes of both groups were obtained using the footprint method with help of Solid worker software. The physiological cost index (PCI) of the participants was measured by the use of a heart rate monitoring system (Polar Electro, Finland). The differences between the PCIs of both groups of participants was determined using a t test. In addition, the influence of using an insole was evaluated using a paired t test. Result. The energy consumption of flat-footed individuals differed significantly from that of normal individuals (the PCIs of normal and flat-footed individuals were 0.357 and 0.368 beats/m, respectively). Using a foot insole improved the performance of the flat-footed individuals during walking. Conclusion. The PCI of flat-footed individuals is more than that of normal participants as a result of misalignment of foot structure. Moreover, using a foot insole improved foot alignment and decreased energy consumption. Levels of Evidence: Therapeutic, Level III: comparative case series

The Impact

In light of the recent launch of the Minimum Energy Efficiency Standard and its expected impact on the commercial buildings sector, this study investigated the impact of adding cooling systems on the annual energy consumption, carbon dioxide emissions and energy performance certificate (EPC) rating of an existing UK hotel. Thermal Analysis Software (TAS) was used to conduct the study, and the baseline model was validated against the actual data. As is the current accepted procedure in EPC generating in the UK, the cooling set points of the guest rooms were set to 25 °C, resulting in a small increase in the annual energy consumption and emission rates, but not enough to change the energy performance certificate rating. Also, it was found that an improvement in energy consumption and energy performance certificate rating of the hotel would be achieved if the new systems replaced the existing heating systems in the guest rooms. Further simulations investigated more realistic situations, in which occupants may decide to keep their rooms at cooler temperatures. The results from this round of simulations showed considerable increase in the energy consumption and emissions of the building; however, these results would not be considered in the current approved procedure for EPC generating.

New Energy Vehicles

In recent years, in order to improve Beijing's air quality and reduce vehicle emissions, the Beijing Municipal Government promotes the popularization of new energy vehicles through purchase subsidies, plate lottery, and driving restriction policy. However, the increase in the number of new energy vehicles and the increase in the number of vehicles travelling on roads have intensified the traffic pressure in Beijing. Traffic congestion has increased the emissions of motor vehicle exhaust in turn, resulting in higher socio-economic costs. Based on the actual data of Beijing, this paper quantitatively analyzes the economic cost of new energy vehicle policies by discussing the impact of current new energy vehicle policies on time, energy consumption and tail gas cost. Empirical results show that during the implementation period of the new energy vehicle policy, time cost and tail gas cost increase, energy consumption cost decreases, and the overall economic cost of the policy implementation period increases from 50 million yuan to 321 million yuan.

Abstract The present paper deals with the use of systems and devices with artificial intelligence in the motor vehicle driving. The main objective of transport operations is a transportation planning with minimum energy consumption. There are various methods for energy saving, and the paper discusses one of them – proper planning of transport operations. To gain proper planning it is necessary to involve the system and devices with artificial intelligence. They will display possible developments in the choice of one or another transport plan. Consequently, it can be supposed how much the plan is effective against the spent energy. The intelligent device considered in this paper consists of an algorithm, a database, and the internet for the connection to other intelligent devices. The main task of the target function is to minimize the total downtime at intermediate stations. A specific unique PHP-based computer model was created. It uses the MySQL database for simulation data storage and processing. Conclusions based on the experiments were made. The experiments showed that after optimization, a train can pass intermediate stations without making multiple stops breaking and accelerating, which leads to decreased energy consumption.

Information Adoption

Purpose – The purpose of this paper is to investigate the impact of features involving online product reviews (OPRs) on information adoption by new product developers (NPDs). Design/methodology/approach – In total, 143 OPRs on a specific product on Amazon.com were collected as the sample of this study. Using content analysis ratings and observed data in OPRs, the research model was analyzed with the partial least squares (PLS) method. Findings – Results suggest that helpfulness rating and the degree of referencing are positively associated with NPDs’ information adoption, while the extremeness of product rating is negatively associated. Moreover, title attractiveness mitigates the negative relationship between the extremeness of product rating and information adoption. Practical implications – The findings provide interesting insight for NPDs who visit e-commerce sites to learn through electronic word-of-mouth (eWOM) communication. OPRs with a higher degree of referencing, higher helpfulness rating, moderate level of product rating, and higher degree of title attractiveness are better adopted by NPDs. Social implications – This paper investigates the value of OPRs for a specific group of information users and suggests that information about products generated by anonymous consumers can be crucial. Originality/value – While extant studies have focussed on the impacts of OPRs on consumers’ purchasing intention and behavior, this paper is among the first attempts to investigate the impacts of OPRs on developers’ information adoption. Therefore, it contributes to the body of knowledge on knowledge transfer from consumers to business as well as the information adoption literature.

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.

The Impact

With the rise in awareness of energy efficient buildings and adoption of mandatory energy conservation codes across the globe, significant change is being observed in the way the buildings are designed. With the launch of Energy Conservation Building Code (ECBC) in India, climate responsive designs and passive cooling techniques are being explored increasingly in building designs. Of all the building envelope components, roof surface has been identified as the most significant with respect to the heat gain due to the incident solar radiation on buildings, especially in tropical climatic conditions. Since ECBC specifies stringent U-Values for roof assembly, use of insulating materials is becoming popular. Along with insulation, the shading of the roof is also observed to be an important strategy for improving thermal performance of the building, especially in Warm and humid climatic conditions. This study intends to assess the impact of roof shading on building’s energy performance in comparison to that of exposed roof with insulation. A typical office building with specific geometry and schedules has been identified as base case model for this study. This building is simulated using energy modelling software ‘Design Builder’ with base case parameters as prescribed in ECBC. Further, the same building has been simulated parametrically adjusting the amount of roof insulation and roof shading simultaneously. The overall energy consumption and the envelope performance of the top floor are extracted for analysis. The results indicate that the roof shading is an effective passive cooling strategy for both naturally ventilated and air conditioned buildings in Warm and humid climates of India. It is also observed that a fully shaded roof outperforms the insulated roof as per ECBC prescription. Provision of shading over roof reduces the annual energy consumption of building in case of both insulated and uninsulated roofs. However, the impact is higher for uninsulated roofs (U-Value of 3.933 W/m2K), being 4.18% as compared to 0.59% for insulated roofs (U-Value of 0.33 W/m2K).While the general assumption is that roof insulation helps in reducing the energy consumption in tropical buildings, it is observed to be the other way when insulation is provided with roof shading. It is due to restricted heat loss during night.

The purpose of this study is to examine the impact of Shariah governance and corporate governance (CG) on the risk management practices (RMPs) of local Islamic banks and foreign Islamic banks operating in Malaysia. The Shariah governance comprises the Shariah review (SR) and Shariah audit (SA) variables. The study also evaluates the level of RMPs, CG, SR, and SA between these two type of banks. With the aid of SPSS version 20, the items for RMPs, CG, SR, and SA were subjected to principal component analysis (PCA). From the PCA, one component or factor was extracted each for the CG, SR, and RMPs while another two factors were extracted for the SA. Primary data was collected using a self-administered survey questionnaire. The questionnaire covers four aspects ; CG, SR, SA, and RMPs. The data received from the 300 usable questionnaires were subjected to correlation and regression analyses as well as an independent t-test. The result of correlation analysis shows that all the four variables have large positive correlations with each other indicating a strong and significant relationship between them. From the regression analysis undertaken, CG, SR, and SA together explained 52.3 percent of the RMPs and CG emerged as the most influential variable that impacts the RMPs. The independent t-test carried out shows that there were significant differences in the CG and SA between the local and foreign Islamic banks. However, there were no significant differences between the two types of the bank in relation to SR and RMPs. The study has contributed to the body of knowledge and is beneficial to academicians, industry players, regulators, and other stakeholders.
