A Deep Reinforcement Learning scheme for Battery Energy Management
2020
Deep reinforcement learning is considered promising for many energy cost optimization tasks in smart buildings. How-ever, agent learning, in this context, is sometimes unstable and unpredictable, especially when the environments are complex. In this paper, we examine deep Reinforcement Learning (RL) algorithms developed for game play applied to a battery control task with an energy cost optimization objective. We explore how agent behavior and hyperparameters can be analyzed in a simplified environment with the goal of modifying the algorithms for increased stability. Our modified Deep Deterministic Policy Gradient (DDPG) agent is able to perform consistently close to the optimum over multi…
A system-level power saving approach for cellular networks with microcells/picocells
2011
Network power consumption reduction has recently become an active research topic. In this paper, we propose a novel approach to save power consumption of a three-cell microcellular network. When the traffic load in the middle cell is low, it can be switched-off and its users are covered. This is enabled by increasing the transmission power of one sector antenna in the two neighboring cells. Numerical results show that by increasing antenna transmission power of the two sectors, the overall network power consumption can be reduced.
Influence of oxygen vacancies on the photorefractive effect in barium titanate single crystals
1990
Abstract In this work the influence of the vacancies concentration in pure BaTiO3 single crystals is studied. It is shown that the oxidation and the reduction do not change the electrooptic coefficients. The reduction modifies the nature of the majority carriers. An evaluation of the trap density N is done.
Polarographische Untersuchungen an monomeren und polymeren N-Chlorcarbonamiden
1979
The polarographic reduction of low molecular and high molecular N-chlorocarboxamides at the dropping mercury electrode proceeds in two one-electron-transfer steps, which are highly irreversible. In the case of the low molecular models 1 and 2 the reaction is diffusion-controlled, whereas in the case of the poly(N-chloroamide) 3 the reaction is adsorption-controlled. Reduction of several poly(N-chloroamide)s shows always two reduction waves with a distance of 0,5 V. There is, however, no relation between the polyamide-type and the position of the half-wave potentials. The polarographic reduction can be used as an analytical method for quantitative determination of N-chlorocarboxamide groups …
ChemInform Abstract: The Reduction of α,β-Unsaturated Nitriles and α- Halonitriles with Sodium Hydrogen Telluride.
2010
Abstract Sodium hydrogen telluride reacts chemoselectively with α,β-unsaturated nitriles and α-halonitriles linked to aromatic and aliphatic substituents to give the corresponding saturated nitriles with good yields.
Applications and numerical convergence of the partial inverse method
2006
In 1983, J.E. Spingarn introduced what he called the Partial Inverse Method in the framework of Mathematical Programming. Since his initial articles, numerous applications have been given in various fields including Lagrangian multipliers methods, location theory, convex feasibility problems, analysis of data, economic equilibrium problems. In a first part of this paper we give a survey of these applications. Then by means of optimization problems relevant to location theory such as single and multifacility minimisum or minimax location problems, we examine the main advantages of the algorithm and we point out its drawbacks mainly concerning the rate of convergence. We study how different p…
Premio di Laurea “Ametek Scientific Instruments”: Electrochemical Conversion of Carbon Dioxide to Formic Acid. Study of the Effect of the Operating P…
2017
Electrochemical conversion of CO2 is considered one of the more appealing approaches to introduce renewable energy in the chemical and energy chain and to mitigate the greenhouse gases effect. In this work, the reduction of carbon dioxide was performed in undivided electrochemical cell to produce formic acid, which is one of the highest value-added chemicals and economically feasible for large-scale applications (1). It is well known that the main hurdle of the reduction of CO2 from water solution is the low CO2 solubility in water. In order to overcome this obstacle, a specific investigation on the effect of the CO2 pressure and other operating parameters at tin flat cathodes was carried o…
Must Ethics for Moral Neuroeducation Be Naturalistic?
2019
The naturalization of ethics is being promulgated in a range of domains, one of which is neuroscience, hence the question stated in this chapter’s title. In order to answer this question, we must clarify what is meant by “naturalistic”; is it used in a reductionist sense? Or solely to refer to a concern for incorporating a neuroscientific perspective into the study of ethics, thereby without any intention that it should predominate within philosophical discussion?
¿Conduce la neurociencia a una naturalización del deontologismo? «Juicios morales deontológicos» en perspectiva neuroética
2017
A tenor de las investigaciones en el campo de la neuroética y más en concreto en la teoría del proceso dual del juicio moral en autores como Joshua Greene, nos planteamos la cuestión de si la neurociencia conduce necesariamente a una «naturalización del deontologismo». De este modo en nuestra comunicación ponemos en cuestión un modo de hacer neurociencia que pretenda reducir el deontologismo a un tipo de respuesta exclusivamente emocional. Frente a este modelo planteamos otra forma de hacer «neuroética» donde se consideren las estructuras psicofísicas de la moralidad sin incurrir en el reduccionismo miope naturalista. Se trata, por lo tanto, de descubrir la neurociencia de la ética, esto es…
Tinkering and Evolution
2015
Jacob is one of the fathers of modern Biology, and in his monumental work The Logic of Life he recounts the polarity that has always existed in biological science between analytical and synthetic traditions, between reductionism and holism . Interestingly, however, although he is a model example of the reductionist tradition and one of the fathers of Molecular Biology, Jacob does not rule out the possibility of emergent properties.
