Face Processing on Low-Power Devices
2009
The research on embedded vision-based techniques is considered nowadays as one of the most interesting matters of computer vision. In this work we address the scenario in which a real-time face processing system is needed to monitor people walking through some locations. Some face detection (e.g., Viola-Jones face detector) and face recognition (e.g., eigenfaces) approaches have reached a certain level of maturity, so we focused on the development of such techniques on embedded systems taking into account both hardware and software constraints. Our goal is to detect the presence of some known individuals inside some sensitive areas producing a compact description of the observed people. Cap…
Channel Occupancy-Based Dynamic Spectrum Leasing in Multichannel CRNs: Strategies and Performance Evaluation
2016
Spectrum leasing has been proposed as an effective approach for enabling more flexible spectrum utilization in CRNs. In CRNs, a primary network (PN) which consists of multiple primary users (PUs) can lease part of the licensed spectrum to secondary users (SUs) in exchange for operational benefits. The focus of this study is to investigate how and to what extent the PN allows spectrum leasing in CRNs, considering the QoS requirements of the PN and the secondary network (SN). Correspondingly, we propose two dynamic spectrum leasing strategies, which can improve the QoS performance of SUs while ensuring sufficient remuneration for PUs. In order to dynamically adjust the portion of leased bandw…
Improving big-data automotive applications performance through adaptive resource allocation
2019
In automotive applications, connected vehicles (CVs) can collect various information (external temperature, speed, location, etc.) and send them to a central infrastructure for exploitation in a wide range of applications: Eco-Driving, fleet management, environmental monitoring, etc. Such applications are known to generate a massive volume of data that is processed in real or near real time (i.e., data streams) depending on the target application requirements. To handle this data volume, big data architectures, based on stream computing paradigm, are usually adopted. Within this paradigm, data are continuously processed by a set of operators (elementary operations) instances. Further, a str…
The disenchantment of professionals in a new, implemented model of primary health care in Spain: A structural equations model
1992
Abstract A new model of primary health care has been progressively implemented in Spain. Previous research (Peiro and Gonzalez-Roma 1991) suggested that the implementation of this new model has produced a kind of disenchantment—that is, an experience of negative surprise—among health care professionals involved. In the present paper, a structural equations model about the antecedents and consequences of the experience of surprise is tested in a sample of 432 health care professionals working in 44 Primary Health Care Teams (PHCT). The results obtained showed that the number of uncovered functions in the PHCTs, the discrepancy between actual and desired time allocation, and the assessment of…
Queue Based Dynamic Charging Resource Allocation and Coordination for Heterogeneous Traffic in an Electrical Vehicle Charging Station
2021
Electric vehicle (EV) fast-charging stations (CSs) with innovative operation management strategies can help to meet the growing EV charging needs. Despite the short charging time associated with th...
No room for males in caves : Female‐biased sex ratio in subterranean amphipods of the genus Niphargus
2021
Sex allocation theory predicts that the proportion of daughters to sons will evolve in response to ecological conditions that determine the costs and benefits of producing each sex. All else being equal, the adult sex ratio (ASR) should also vary with ecological conditions. Many studies of subterranean species reported female-biased ASR, but no systematic study has yet been conducted. We test the hypothesis that the ASR becomes more female-biased with increased isolation from the surface. We compiled a dataset of ASRs of 35 species in the subterranean amphipod Niphargus, each living in one of three distinct habitats (surface-subterranean boundary, cave streams, phreatic lakes) representing …
Exposing ecological and economic costs of the research-implementation gap and compromises in decision making
2018
The frequently discussed gap between conservation science and practice is manifest in the gap between spatial conservation prioritization plans and their implementation. We analyzed the research-implementation gap of one zoning case by comparing results of a spatial prioritization analysis aimed at avoiding ecological impact of peat mining in a regional zoning process with the final zoning plan. We examined the relatively complex planning process to determine the gaps among research, zoning, and decision making. We quantified the ecological costs of the differing trade-offs between ecological and socioeconomic factors included in the different zoning suggestions by comparing the landscape-l…
Zasady finansowania współpracy euroregionalnej na przykładzie Euroregionu Silesia
2016
The tasks of the Euroregion Silesia in the pre-accession program Phare CBC were different on both sides of the border and were limited contem- porary rules that force countries not belonging to the community of the EU. After the entry of both countries to the EU and the incorporation of the program INTERREG III A, the activities of the Euroregion as the so-called. Fund Manager of the Micro sometimes codified and today authorities of both parts Euroregion perform tasks in close cooperation with each other. With the Fund may be funded projects in the field of culture, sports, education, education, tourism, the environment, eco- nomic development planning, use of information technologies and o…
Adaptacja gospodarstw rolnych województwa opolskiego do nowych warunków gospodarowania
2012
Nowe spojrzenie na miejsce, rolę i funkcje rolnictwa w gospodarce wiąże się z próbą odpowiedzi na pytanie: jak jego potencjały rozwojowe mogą być wykorzystane jako czynniki wzrostu gospodarczego. Na płaszczyźnie mikroekonomicznej jest ważna nie tylko ocena efektywności wykorzystywanych czynników produkcji, ale również identyfikacja bodźców wpływających na decyzje kierowników gospodarstw rolnych dotyczące sposobów ich aktywności ekonomicznej. Ta druga kwestia jest istotna, ponieważ otoczenie instytucjonalne zreformowanej WPR kieruje rolnictwo na ścieżkę zrównoważonego rozwoju, co wymaga ukształtowania nowych typów jego wielofunkcyjności. W pracy jako mechanizm procesu zaproponowano „cele aut…
Factors Associated with Decisions for Initial Dosing, Up-Titration of Propiverine and Treatment Outcomes in Overactive Bladder Syndrome Patients in a…
2021
Two doses of propiverine ER (30 and 45 mg/d) are available for the treatment of overactive bladder (OAB) syndrome. We have explored factors associated with the initial dosing choice (allocation bias), the decision to adapt dosing (escalation bias) and how dosing relative to other factors affects treatment outcomes. Data from two non-interventional studies of 1335 and 745 OAB patients, respectively, receiving treatment with propiverine, were analyzed post-hoc. Multivariate analysis was applied to identify factors associated with dosing decisions and treatment outcomes. Several parameters were associated with dose choice, escalation to higher dose or treatment outcomes, but only few exhibited…
