In a walking cycle design, maximizing the upright balance should be considered in addition to the kinematic constraints, energy consumption rate must be considered. The purpose of this study is to find the optimal step length obtained for each person according to the physical features. In this research, in order to minimize energy consumption rate by considering maximum balance two cost functio...

Abstract This study was conducted to reduce energy consumption and consumed electricity costs at drinking water pumping stations in villages located at the central part of Khorramabad city in 2017. In this study, 10 wells and pumping stations from a total of 48 wells and pumping stations in Khorramabad were selected randomly. The energy consumption, energy intensity, the effect of the capacito...

In this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between T6 and L2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. All subjects walked at their preferred speed on a figureof- eight track. Normal subjects also walked at slower and faster speeds. Oxygen consumption, heart rate and rating of perceived exertion were measured. In...

With support of GIS tools and Theil index, the spatial variance of urban energy consumption in China was discussed in this paper through the parallel comparison and quantitative analysis of the 30 provincial capital cities of mainland China in 2005, in terms of scale, efficiency and structure. The indicators associated with urban energy consumption show large spatial variance across regions, po...

In France, non-residential buildings account for a significant part in energy consumption. Moreover, a large part of this consumption is due to Heating, Ventilation and Air-Conditioning (HVAC) systems, which are generally badly handled. So, the present work deals with an efficient approach allowing energy consumption to be minimized while ensuring thermal comfort. In this sense, a predictive co...

In this paper we investigate the problem of uneven energy consumptions in a large class of many-to-one sensor networks. In a many-to-one sensor network, all sensor nodes generate constant bit rate (CBR) data and send them to a single sink via multihop transmissions. This type of sensor networks has many potential applications such as environmental monitoring and data gathering. Based on the obs...

In this study, an attempt is made to investigate the effect of energy consumption on environmental pollution in Iran. For this purpose, a basic model (the whole economy) and three sectoral models (household, commercial and public; industry and transportation) has been estimated with an autoregressive distributed lag approach in the period 1971-2017. The results of the model estimation show the ...

E nergy consumption has increased significantly in Iran during the recent decades. In this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. The input-output tables of Iran for the years 1988 and 2001 have been employed as the database of the model. The innovation of this research allows the researchers to stud...
