Energy Management and Smart Grids
2013
The paper outlines energy management concepts and the smart grid evolution. The necessity of considering energy management as a crucial innovation in load supplying to permit a more powerful penetration of renewable energy usage at the building and city level and to perform energy savings and CO2 emissions reduction is pointed out. The driving factors to enhance the current power distribution are presented, and the benefits concerning smart grids are underlined. In the paper, a specific energy management analysis is reported by considering all the electric value chain, and the demand-side management and distributed on site control actions are described. To verify the benefit of energy manag…
Alcohol Consumption and Long-Term Labor Market Outcomes
2017
This paper examines whether alcohol consumption is related to long-term labor market outcomes. We use twin data for Finnish men and women matched to register-based individual information on employment and earnings. The twin data allow us to account for the shared environmental and genetic factors. The quantity of alcohol consumption was measured by weekly average consumption using self-reported data from three surveys (1975, 1981 and 1990). The average of an individual's employment months and earnings were measured in adulthood over the period 1990–2009. The models that account for the shared environmental and genetic factors reveal that former drinkers and heavy drinkers both have almost 2…
Uwarunkowania i przejawy różnicowania modelu konsumpcji na Śląsku w latach 2004-2015
2017
Przedmiotem badań przedstawionych w artykule są długookresowe zmiany modelu konsumpcji na Śląsku, czyli w trzech województwach przygranicznych – śląskim, opolskim i dolnośląskim, a także identyfi kacja ważniejszych czynników warunkujących zróżnicowanie realizowanych przez gospodarstwa domowe modeli konsumpcji. W oparciu o dane z panelowych badań GUS budżetów gospodarstw domowych w latach 2004–2015 przeprowadzono ekonometryczną analizę wpływu na poziom i strukturę wydatków gospodarstw domowych oraz takich ich cech, jak poziom oraz główne źródło dochodów, miejsce zamieszkania, wiek czy wykształcenie osoby odniesienia (głowy domu). Przyjęto przy tym założenie, że o modelu konsumpcji można wnio…
Demographic and Economics Determinants of Differentiation of Consumption Model in Silesia in Poland in the Years 1994-2013
2016
The research presented in this article focuses on long-term changes in consumption patterns in Silesia, which covers three border provinces of Poland - Silesia, Opole Voivodship and Lower Silesia. The investigation concerns also identification of the most important factors determining differentiation of consumption patterns implemented by households in that region. Based on data of the Central Statistical Office in Warsaw coming from the panel research on households’ budgets in 2004-2013 there was conducted an econometric analysis of few characteristics of households (such as: the level and the main source of income, place of residence, age or educational level of reference person (leader o…
The Analysis of the Digital Economy and Society Index in the EU
2019
Abstract The paper analyzes the Digital Economy and Society Index (DESI), which characterizes the development of digital economy. Based on the data of 28 European countries for 2013–2018, using the panel regression, we studied the influence of the consumption index growth by the purchasing power parity and unemployment among the active population on the structural units of DESI. It is shown that a 1% increase in the consumption index results in about 0.2 increase in the DESI, and an increase in unemployment by 1% leads to about 0.2 DESI decline. It is also shown that the 98% value of DESI is actually determined by its previous trends, and therefore it is impossible to increase this index ra…
La evolución energética del sector español de baldosas cerámicas
2014
espanolEl presente texto analiza como ha ido evolucionando el consumo y la eficiencia energetica de la industria espanola de baldosas ceramicas durante el siglo XX, y explora las posibilidades que se le plantean en el siglo XXI. Durante el pasado siglo este sector industrial acometio tres transiciones radicales al pasar de los combustibles tradicionales de biomasa a los hidrocarburos liquidos (fueloleo y gasoleo), y posteriormente a los gaseosos, principalmente gas natural. Aunque la informacion que permite evaluar de manera fiable la eficiencia energetica real en las plantas de fabricacion no es facil de obtener, los datos disponibles indican que se ha llegado a una elevada eficiencia con …
Tumour oxygenation during fractionated radiotherapy--comparison with size-matched controls.
1999
The effect of fractionated irradiation on the oxygenation status of experimental tumours was investigated using polarographic assessment of the pO2 distribution. Since an improvement in tumour oxygenation could simply be the result of tumour shrinkage, a comparison of pO2 readings of untreated size-matched control tumours was performed. Irradiation was carried out using 6 fractions of 6 Gy applied within 11 days. A comparison of polarographic pO2 data with size-matched untreated tumours revealed a significant improvement in oxygenation after the irradiation. The median pO2 was 0.9+/-0.1 mm Hg for unirradiated tumours at a volume of 180 mm3, while the corresponding data for irradiated tumour…
Positioning the Supply of Live Performance: Innovative Managerial Practices Relating to the Interaction of Spectator, Performance and Venue
2006
Because of the abundance of offerings, the question of positioning with regard to live performances is becoming increasingly crucial for managers in the cultural sector. The authors address this issue by proposing original means of differentiation that managers can use in order to reinforce the identity of their offerings. The authors point to the need for analysis of the relationship between the public and the spectacle (central focus of positioning), highlighting the various facets that structure this positioning. They then examine the interaction between the public and the cultural venue (peripheral focus of positioning). Such a framework of consumption experiences offers promising solut…
An Efficient Implementation of Parallel Parametric HRTF Models for Binaural Sound Synthesis in Mobile Multimedia
2020
The extended use of mobile multimedia devices in applications like gaming, 3D video and audio reproduction, immersive teleconferencing, or virtual and augmented reality, is demanding efficient algorithms and methodologies. All these applications require real-time spatial audio engines with the capability of dealing with intensive signal processing operations while facing a number of constraints related to computational cost, latency and energy consumption. Most mobile multimedia devices include a Graphics Processing Unit (GPU) that is primarily used to accelerate video processing tasks, providing high computational capabilities due to its inherent parallel architecture. This paper describes…
Qualitative Evaluation of the STOEMP Network in Ghent: An Intersectoral Approach to Make Healthy and Sustainable Food Available to All
2020
The STOEMP network is, to our knowledge, one of the first initiatives to bring different sectors together in a municipality so as to increase accessibility to healthy and sustainable foods for all, with particular attention for the disadvantaged population. This qualitative study aimed to gain an in-depth insight into how the STOEMP network aims to reach its goal of making healthy, sustainable food available to everyone, through an intersectoral, collaborative process, exploring the facilitators and challenges of taking a systems-oriented approach to achieving this. Interviews were conducted among 15 stakeholders of the STOEMP network between March&ndash
