The Impact

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.

New Buildings

The climate is changing very fast today, and this is not natural. We are experiencing the impact of climate change in many aspects. It is also expected to impact the performance of buildings badly in due course of time. In recent years, many countries started investing to evaluate the energy performances of the buildings and opting for the best suited energy-saving measures. However, this concept may be new in the context of Bhutan. However, the author expects that this new concept may revolutionize the building construction sectors in Bhutan. Many studies show that buildings are one of the world’s largest consumers of energy, and on the other hand, strategies are available to reduce energy consumption. The strategies can be applied right from the design phases for the new buildings and retrofits for the old buildings. In order to apply the best strategies of energy consumption reduction and to understand building energy consumption patterns, an evaluation of the building’s energy performance needs to be carried out.

The Impact

Energy consumption reduction in the residential sector is crucial for mitigating global warming. This has prompted researchers to investigate the determinants of household energy consumption from various aspects. However, previous studies have not examined the impact of time allocation on energy consumption, primarily because of the lack of surveys that simultaneously examine time allocation and energy consumption. We conducted an original survey of 547 Japanese households to examine whether time allocation affects their electricity consumption. We divided a 48-hour period into 192 time slots and asked the households to choose one of the 20 types of actions listed for each slot. We also collected information on the socioeconomic background and electricity consumption of the households. After controlling for various factors that affect household electricity consumption, we examined whether time allocation determines electricity consumption. The empirical result of our study revealed that while a married male’s bedtime does not affect electricity consumption, a married female’s bedtime does. This suggests that it is essential to understand the daily habits of consumers for proposing effective energy conservation measures.Keywords: Electricity Usage, Household, Time Allocation

The Impact

In this paper, we demonstrate the feasibility and efficiency of approximate computing techniques (ACTs) in the embedded Support Vector Machine (SVM) tensorial kernel circuit implementation in tactile sensing systems. Improving the performance of the embedded SVM in terms of power, area, and delay can be achieved by implementing approximate multipliers in the SVD. Singular Value Decomposition (SVD) is the main computational bottleneck of the tensorial kernel approach; since digital multipliers are extensively used in SVD implementation, we aim to optimize the implementation of the multiplier circuit. We present the implementation of the approximate SVD circuit based on the Approximate Baugh-Wooley (Approx-BW) multiplier. The approximate SVD achieves an energy consumption reduction of up to 16% at the cost of a Mean Relative Error decrease (MRE) of less than 5%. We assess the impact of the approximate SVD on the accuracy of the classification; showing that approximate SVD increases the Error rate (Err) within a range of one to eight percent. Besides, we propose a hybrid evaluation test approach that consists of implementing three different approximate SVD circuits having different numbers of approximated Least Significant Bits (LSBs). The results show that energy consumption is reduced by more than five percent with the same accuracy loss.
