Wireless Sensor Network Operating System Design Rules Based on Real-World Deployment Survey

2013

Wireless sensor networks (WSNs) have been a widely researched field since the beginning of the 21st century. The field is already maturing, and TinyOS has established itself as the de facto standard WSN Operating System (OS). However, the WSN researcher community is still active in building more flexible, efficient and user-friendly WSN operating systems. Often, WSN OS design is based either on practical requirements of a particular research project or research group's needs or on theoretical assumptions spread in the WSN community. The goal of this paper is to propose WSN OS design rules that are based on a thorough survey of 40 WSN deployments. The survey unveils trends of WSN applic…

Arc routing problems with drones

2023

La tecnología emergente de vehículos aéreos no tripulados, comúnmente conocidos como drones, ha brindado nuevas oportunidades para los profesionales de la logística urbana en la última década. El transporte ha jugado siempre un papel crucial en la sociedad y en la economía, y un motor fundamental del desarrollo económico en los últimos tiempos ha sido la inversión en sistemas de transporte cada vez más eficientes. Los drones presentan ventajas atractivas en comparación con los vehículos terrestres estándar, como evitar la congestión en las redes viales, eliminar el riesgo del personal en operaciones de difícil acceso u obtener una mayor precisión de medición en la inspección de infraestruct…

Statistical properties of general Markov dynamical sources: applications to information theory

2004

In \textitDynamical sources in information theory: fundamental intervals and word prefixes, B. Vallée studies statistical properties of words generated by dynamical sources. This is done using generalized Ruelle operators. The aim of this article is to generalize sources for which the results hold. First, we avoid the use of Grotendieck theory and Fredholm determinants, this allows dynamical sources that cannot be extended to a complex disk or that are not analytic. Second, we consider Markov sources: the language generated by the source over an alphabet \textbfM is not necessarily \textbfM^*.

Il piano economico finanziario nelle concessioni di servizi

2021

The motivational system contained in the sentence of the Council of State of 13 October 2020, n. 6168 suggests reflecting on the function performed by the economic and financial plan in the matter of service concession contract as well as on its possible qualification as an integral element of the economic offer presented by the economic operator

Gli operatori economici nel labirinto dei gravi illeciti professionali e il periodo triennale di esclusione dalla gara dall’accertamento definitivo

2019

In the presence of a difficult system, such as that of serious professional offences, art. 80, paragraph 5, lett. c), Legislative Decree no. 50 of 2016, this work aims, first of all, to identify possible solutions suitable for avoiding choices of exclusion from the tender, potentially arbitrary, by the station contractor and to ensure a tender procedure based on compliance with the principle of certainty of law and on the constitutional principles referred to in Articles 3, 41 and 117, paragraph 2 lett. e), Constitution. We then focus on the issue of the temporal relevance of serious professional offences, such as significant deficiencies in the execution of a previous procurement contract,…

Regularization Preserving Localization of Close Edges

2007

International audience; In this letter, we address the problem of the influence of neighbor edges and their effect on the edge delocalization while extracting a neighbor contour by a derivative approach. The properties to be fulfilled by the regularization operators to minimize or suppress this side effect are deduced, and the best detectors are pointed out. The study is carried out in 1-D for discrete signal. We show that among the derivative filters, one of them can correctly detect our model edges without being influenced by a neighboring transition, whatever their separation distance is and their respective amplitude is. A model of contour and close transitions is presented and used through…

“To Own, or not to Own?” A multilevel analysis of intellectual property right policies' on academic entrepreneurship

2017

The political environment around universities has led them to create an infrastructure to manage academic inventions. While some consider that the advantages of a university entrepreneurial structure outweigh any potential negative effects, others question their detrimental effect on academic scientists’ entrepreneurial behavior. However, this debate remains unresolved as none of these two views have been fully empirically supported. Using multilevel models for a population of 2230 professors in 27 universities in Canada (82 individuals per unit on average), we test the effect of three features of institutional intellectual property right policy characteristics, namely, property rights (own…
