Optimal switches in multi-inventory systems
2007
Given a switched multi-inventory system we wish to find the optimal schedule of the resets to maintain the system in a safe operating interval, while minimizing a function related to the cost of the resets. We discuss a family of instances that can be solved in polynomial time by linear programming. We do this by introducing a set-covering formulation with a totally unimodular constraint matrix.
A Research Review on Building Information Modeling in Construction―An Area Ripe for IS Research
2012
Published version of article of an article in the journal: Communications of the Association for Information Systems. Also available from the publisher : http://http://aisel.aisnet.org/cais/vol31/iss1/10/ This article presents a review of the research on Building Information Modeling (BIM) in construction, with the aim of identifying areas in this domain where IS research can contribute. The concept of BIM comprises an infrastructure of IT tools supporting collaborative and integrated design, assembly, and operation of buildings. This integrated construction approach, with all stakeholders editing or retrieving information from commonly shared models, requires major changes to well-establis…
Perceived-Value-driven Optimization of Energy Consumption in Smart Homes
2020
Residential energy consumption has been rising rapidly during the last few decades. Several research efforts have been made to reduce residential energy consumption, including demand response and smart residential environments. However, recent research has shown that these approaches may actually cause an increase in the overall consumption, due to the complex psychological processes that occur when human users interact with these energy management systems. In this article, using an interdisciplinary approach, we introduce a perceived-value driven framework for energy management in smart residential environments that considers how users perceive values of different appliances and how the us…
Quality of life ranking of Spanish cities: A non-compensatory approach
2021
Abstract Urban areas are hubs of economic activity, but also consumption centers where a high quality of life may attract human capital and increase prospects of economic growth and well-being. We rank 73 Spanish cities on the basis of 35 individual indicators covering three basic facets of quality of life: socio-economic performance, general livability conditions, and residents' health status. We reject the conventional approach of compensability among different quality of life dimensions in favor of a Condorcet-inspired non-compensability approach. We obtain three partial composite indicators, one for each of the aforementioned dimensions, and a global indicator that synthesizes the three…
Social Media News: Motivation, Purpose and Usage
2013
This paper presents the results of an online survey which was conducted to analyse the use of social web in the context of daily news. Users' motivation and habit in the news consumption were focused. Moreover, users' news behaviour was distinguished in three purposes such news consumption, news production and news dissemination to find out if the usage has a passive or active character. In a second step it was questioned which social software is used for which purpose. In conclusion users appreciate social software for features such as interactivity and information that traditional media does not provide. Among the social web platforms users prefer social networking sites as well as videos…
REDU : revista de docencia universitaria
2014
[ES] Desde su origen, la misión de la universidad ha sido formar profesionales y especialistas en diversas áreas de conocimiento, pero también, la formación de una auténtica ciudadanía, responsable y comprometida éticamente con la realidad social que la rodea. El artículo presenta una contribución a los debates sobre una nueva conceptualización de la iniciativa empresarial social, así como sobre el desarrollo de planes de estudio en el espacio universitario que expliciten procesos de enseñanza-aprendizaje en emprendimiento social.Aplicamos el método de análisis de contenido para llevar a cabo una revisión crítica de los títulos universitarios que ofrecen las universidades públicas valencian…
Orbits of bounded bijective operators and Gabor frames
2020
This paper is a contribution to frame theory. Frames in a Hilbert space are generalizations of orthonormal bases. In particular, Gabor frames of $L^2(\mathbb{R})$, which are made of translations and modulations of one or more windows, are often used in applications. More precisely, the paper deals with a question posed in the last years by Christensen and Hasannasab about the existence of overcomplete Gabor frames, with some ordering over $\mathbb{Z}$, which are orbits of bounded operators on $L^2(\mathbb{R})$. Two classes of overcomplete Gabor frames which cannot be ordered over $\mathbb{Z}$ and represented by orbits of operators in $GL(L^2(\mathbb{R}))$ are given. Some results about opera…
A note on the iterative object symmetry transform
2004
This paper introduces a new operator named the iterated object transform that is computed by combining the object symmetry transform with the morphological operator erosion. This new operator has been applied on both binary and gray levels images showing the ability to grasp the internal structure of a digital object. We present also some experiments on artificial and real images and potential applications.
Innovative Educational Program for Biogas Production Carried Out at University of Hradec Králové (CZ) and at University of Opole (PL)
2016
Abstract Recently, there is a growing pressure on a rapid construction of agricultural biogas plants, particularly in the Czech-Polish border region. It is an area with large expanses of agricultural land which can serve to supply biogas plants with biomass. This strategy should contribute to harmonize the common agricultural policy of the European Union. A need for qualified operators of these stations on this territory is also increasing. Therefore we first include a demonstration of an education program for students in the field of agricultural waste anaerobic fermentation and biogas production. We present here the first part of an innovative approach which we use in the teaching program…
Strict quasi-concavity and the differential barrier property of gauges in linear programming
2014
Concave gauge functions were introduced to give an analytical representation of cones. In particular, they give a simple and a practical representation of the positive orthant. There is a wide choice of concave gauge functions with interesting properties, representing the same cone. Besides the fact that a concave gauge cannot be identically zero on a cone(), it may be continuous, differentiable and even on its interior. The purpose of the present paper is to present another approach to penalizing the positivity constraints of a linear programme using an arbitrary strictly quasi-concave gauge representation. Throughout the paper, we generalize the concept of the central path and the analyti…
