A Performance Evaluation of Fusion Techniques for Spatio-Temporal Saliency Detection in Dynamic Scenes
2013
International audience; Visual saliency is an important research topic in computer vision applications, which helps to focus on regions of interest instead of processing the whole image. Detecting visual saliency in still images has been widely addressed in literature. However, visual saliency detection in videos is more complicated due to additional temporal information. A spatio-temporal saliency map is usually obtained by the fusion of a static saliency map and a dynamic saliency map. The way both maps are fused plays a critical role in the accuracy of the spatio-temporal saliency map. In this paper, we evaluate the performances of different fusion techniques on a large and diverse datas…
Approaching the whole quality of buildings: methods for the evaluation of economic, energetic and environmental issues
2002
In this work the energy, economy and environment ("three E") requirements for buildings are approached in a joint view, by means of an application to an example building typical of the Italian building stock. With this aim, the rate of involvement of renewable sources is here considered for linking energy and environmental characteristics. Economic and environmental features are joint by means of the evaluation of the cost of the saved CO2. Economic and energy characteristics are linked by means of the cost of the saved energy. In turn, the environmental ambit is addressed by means of the ecoprofile methodology and of the environmental labelling of buildings. This should lead toward a first…
Comparison Between Conventional and Vegetated Roof by Means of a Dynamic Simulation
2015
In this paper, a dynamic simulation of a building located in the Campus University of Palermo, Italy, has been carried out. We considered two different scenarios; in the first one, the building as it is, with a conventional covering, while in the second one the roof was equipped with a green roof. The results of the two simulations have been compared, suggesting that such building component could contribute to the energy savings of the building. However, it has to be considered as part of other possible actions devoted to improve the energy efficiency of the whole building. (C) 2015 The Authors. Published by Elsevier Ltd.

Automatic social distance estimation for photographic studies: Performance evaluation, test benchmark, and algorithm
2022
The social distancing regulations introduced to slow down the spread of COVID-19 virus directly affect a basic form of non-verbal communication, and there may be longer term impacts on human behavior and culture that remain to be analyzed in proxemics studies. To obtain quantitative results for such studies, large media and/or personal photo collections must be analyzed. Several social distance monitoring methods have been proposed for safety purposes, but they are not directly applicable to general photo collections with large variations in the imaging setup. In such studies, the interest shifts from safety to analyzing subtle differences in social distances. Currently, there is no suitabl…
HUMAN RESOURCES IN THE PROCESS OF GRANTING PERFORMANCE IN THE MANAGEMENT OF PRE-UNIVERSITY EDUCATIONAL INSTITUTIONS
2011
Under Romania 's actual development context, pre-university education and mainly the human resources in this field can and need to be an authentic development vector. The paper is meant to be a theoretical analysis and a practical research on the contribution of human resources to granting the performance and quality of the educational management in the pre-university educational institutions, from a systemic, interactive and interdisciplinary perspective, which turns into a reflection but also an applicative issue for the researchers and managers in the educational domain, interested in meeting European and world standards. The research was done on a technical education institution, respec…
Networking strategies as enabler for competitive advantage creation: a market-based and a resource-based perspectives
2010
The purpose of this work is to explore the potential of networking strategy as a source of competitive advantage by integrating market-based and resource-based logics. According to the former logic a firm identifies operations performance objectives as drivers for achieving its wished competitive position and advantage. According to the latter logic the firm achieves a competitive advantage through the obtainment and/or the creation of valuable, rare, imperfectly imitable, and not substitutable resources. Both operations performance objectives and strategic resource needs should, thus, directly affect networking strategy decisions. The question is whether they effectively do and how. In thi…
Achieving operations performance objectives through networking strategy
2010
The main objective of this paper is to investigate how firms make strategic networking decisions in order to pursue competitive advantage. Literature analysis with theory building purposes and two case studies to support our theoretical findings and to explore the linkages between networking strategy and operations performance objectives constitute our research methods. Our analysis led to the definition of networking strategy in terms of decisional dimensions, and found effective linkages between networking decisions made by managers and wished operations performance objectives.
Trade-offs or Complements? : Balancing Diversified Stakeholder Expectations, Institutional Pressures, and Functional Demands in the Strategic Managem…
2019
While scholars and practitioners have warned that business schools are losing their edge in creating and disseminating relevant knowledge in the crosscurrent of environmental demands, the management and organization of higher education institutions (HEIs) have been described as “herding cats” and “organized anarchy”. The teaching–research nexus forms the cornerstone of academic organization and has a quintessential role in strategic management. However, despite the growing body of literature on HEIs’ teaching–research nexus, organization, and environmental changes, few studies have examined the interplay of the three. Therefore, this study combines two contingency-theory views to examine th…
How Relevant Are Risk Perceptions, Effort, and Performance Expectancy in Mobile Banking Adoption?
2018
This article provides a comprehensive overview of the adoption process using evidence from m-banking adoption in Pakistan. A survey design was used and 189 responses were received from across Pakistan and analyzed using Smart PLS application. Findings suggest that research on the effect of risk in the adoption process remains inconclusive. Contrarily, consumers have overcome many fears due to the usefulness, indispensability, high security features, and effort expended in the use of financial services delivered through m-banking. Perceived risk's (PR) direct influence was found to be generally weak. However, PR plays a major role in the pre-adoption process because it's weak and direct inhi…
Can neurophysiological markers of anticipation and attention predict ADHD severity and neurofeedback outcomes?
2021
Abstract Neurophysiological measures of preparation and attention are often atypical in ADHD. Still, replicated findings that these measures predict which patients improve after Neurofeedback (NF), reveal neurophysiological specificity, and reflect ADHD-severity are limited. Methods We analyzed children’s preparatory (CNV) and attentional (Cue-P3) brain activity and behavioral performance during a cued Continuous Performance Task (CPT) before and after slow cortical potential (SCP)-NF or semi-active control treatment (electromyogram biofeedback). Mixed-effects models were performed with 103 participants at baseline and 77 were assessed for pre-post comparisons focusing on clinical outcome p…
