Energy nonequipartition in a collisional model of a confined quasi-two-dimensional granular mixture (American Physical Society, 2020)A collisional model of a confined quasi-two-dimensional granular mixture is considered to analyze homogeneous steady states. The model includes an effective mechanism to transfer the kinetic energy injected by vibration ...
-
(Elsevier Ltd, 2018)This paper presents a method for thermal comfort control for trams which achieves the desired thermal comfort and minimises the power consumption of heating,ventilation and air conditioning (HVAC). Mathematical models of ...
-
(Elsevier, 2003)In several countries (Chile, Bolivia, Argentina and Peru, among others), power plants are dispatched according to merit order, i.e. based on the marginal operating costs of the plants. In this scheme, the operating plant ...
-
(Soc Neuroscience, 2017-06-07)The mechanisms that power the physiological events occurring in cilia, flagella, and microvilli are of fundamental importance for the functions of these important and ubicuous organelles. The olfactory epithelium is mostly ...
-
(2010)Energy restriction decreases bone mineral density (BMD), and epidemiological studies suggest that the risk of weight loss-induced bone loss is greater in lean than in heavier individuals. Our goal in this study was to ...
-
(Wiley, 2020)Cells possess a variety of organelles with characteristic structure and subcellular localization intimately linked to their specific function. While most are intracellular and found in virtually all eukaryotic cells, there ...
-
(1999)A theoretical study is reported of the mechanisms for internal rotation of hydrogen peroxide (HOOH), hydrogen thioperoxide (HSOH) and hydrogen persulphide (HSSH). Calculations at the ab initio HF//6-311G** and MP2//6-311G** ...
-
(2014)The adoption of mobile and ubiquitous solutions that involve participatory or opportunistic sensing increases every day. This situation has highlighted the relevance of optimizing the energy consumption of these solutions, ...

Energy-based iteration scheme of the double-multiple streamtube model in vertical-axis wind turbines (Springer, 2016)Due to their simplicity, blade element momentum models, such as the double-multiple streamtube (DMS) model, are among the most common models to predict the performance of Darrieus vertical-axis wind turbines (VAWTs). A ...
-
(1994)Useful energy-density relationships, connected with the embedding of singly charged postive or negative atomic ions in polar solvents, are developed. The insertion of the atomic charged system into the polarizable host is ...

(IEEE, 2015)This paper first provides a brief survey on existing traffic offloading techniques in wireless networks. Particularly as a case study, we put forward an online reinforcement learning framework for the problem of traffic ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2020)We investigate the energy-efficient channel estimation in wireless networks, where one pilot is inserted for every several data slots to estimate the channel coefficients. Both the channel state information estimation error ...
-
(IEEE Inst Electrical and Electronic Engineering Inc., 2017)The coordinated multiple-point (CoMP) transmission technique recently has been considered as an efficient method to achieve energy-efficient cellular wireless communications and enhance cell-edge user performance. Conventional ...
-
(Elsevier B.V., 2019)© 2018 Elsevier B.V. We propose an energy-efficient resource block (RB) assignment and power control strategy for underlay device-to-device (D2D) communications in multi-cell networks, where more than one D2D pair is allowed ...
-
Energy-Efficient transmission strategies with multiple radios in cognitive radio: Beyond rendezvous (Institute of Electrical and Electronics Engineers Inc., 2018)Cognitive radio (CR) has emerged as a key technology to deal with the frequency spectrum scarcity. The efficient and opportunistic use of the spectrum requires rapid coordination between the secondary users (SUs). Besides, ...
-
(Universidad de Chile, 2022)En el contexto climático actual, reducir el impacto ambiental de la humanidad es más importante y urgente que nunca. Esto debe lograrse sin dejar de lado las mejoras que se han conseguido durante las últimas décadas en la ...
