SREP: An Energy Efficient Relay Protocol for Wireless Sensor Networks
2018
While wireless sensor networks continue to break new grounds in applications, favored by technological innovations, energy efficiency continues to stagnate. Duty cycling remains the most popular and effective technique used to improve energy efficiency and thus lifetime of the network. Nevertheless, duty cycling imposes temporary unavailability on the network leading to deterioration of quality of service. To take care of this rather contradicting reality, this paper proposes Sleep Relay Protocol (SREP). Network nodes are divided into sets according to their location and the sets sleep in relay within a duty cycle period. Two set formation algorithms are proposed at initiation of our propos…
Does Wake-Up Radio Always Consume Lower Energy Than Duty-Cycled Protocols?
2017
Many recent studies anticipate that wake-up radio (WuR) will replace traditional duty-cycled (DC) protocols given its overwhelming performance superiority on energy consumption. Meanwhile, the question on whether WuR performs always better than DC protocols has not been answered explicitly. In this paper, we investigate in-depth the energy consumption performance of WuR by considering various levels of traffic load in a wireless sensor network. By comparing SCM-WuR with both synchronous MAC (S-MAC) and asynchronous MAC (X-MAC), we ascertain that SCM-WuR does consume orders of magnitude lowerenergythanDCprotocolswhentrafficloadislow.Howe ver, our numerical results reveal at the same time that …

Task Contexts in Dutch Mathematics Education
2020
This chapter offers a description of task contexts in mathematics education in the Netherlands. International comparative studies show that the Dutch average percentage of mathematics tasks with real-life connections per lesson exceeds any other country by far. This tradition goes back more than 500 years, when the earliest mathematics textbooks in the Dutch language consisted entirely of tasks, in which mathematics was put to use in commercial contexts. In this chapter characteristics of contexts in mathematics tasks in the Netherlands are studied. Underlying frame is the notion of usefulness, which is a perception by students on future practices outside school. A distinction is made betwe…
GLI OBBLIGHI DI INFORMAZIONE TRA REGOLE DI PROTEZIONE DEL CONSUMATORE E DIRITTO CONTRATTUALE EUROPEO
2013
Less ambitious than the original proposals, the Consumer Rights Directive 2011/83 focuses on the area of information duties and the right of withdrawal in B2C contracts. This article analyses the new rules providing information obligations, and highlights some of the unresolved questions particularly concerning the level of consumer protection, and the remedies for the breach of those obligations. An extensive catalogue of information is now to be given in distance and off-premises contracts; and — according to the existing rules within the Directives on Timeshare Contracts and Package Travel — this catalogue is to be considered an integral part of the contract. According to the Author’s op…
LA CONTRATTAZIONE COLLETTIVA NEGLI STATI UNITI DAL WAGNER ACT AI NOSTRI GIORNI
2016
LA CONTRATTAZIONE COLLETTIVA NEGLI STATI UNITI. DAL WAGNER ACT AI NOSTRI GIORNI. — Riassunto. Il presente lavoro analizza la legislazione statunitense in materia di contrattazione collettiva sin dall’emanazione del Wagner Act nel 1935. Al riguardo, vengono discusse le regole per il riconoscimento dei sindacati nei luoghi di lavoro e per la stipula degli accordi collettivi (principio di maggioranza e rappresentanza esclusiva, obbligo di negoziare secondo buona fede) e per la gestione del conflitto industriale (arbitrato e clausola di tregua): sulla scorta di un approccio storico-critico e dei leading case giurisprudenzialil’articolosottolineailcarattereprettamenteaziendaleeprivatisticodellere…
Riconoscimento e tutela delle fattispecie contrattuali atipiche: interferenze tra logiche argomentative e modelli processuali
2014
La ricerca affronta il tema della tutela delle fattispecie contrattuali atipiche, tenendo distinto il tema dell’atipicità processuale da quello dell’atipicità contrattuale in senso stretto. Ci si sofferma, in particolare, sulle relazioni tra processi logico-argomentativi (ragionamento paradigmatico: assimilazione, analogia; ragionamento sillogistico-deduttivo) e connessi modelli processuali (azione tipica, azione ad exemplum di tipo specifico, azione ad exemplum di tipo generico). Più precisamente, si sottopongono ad analisi i seguenti modelli solutivi. Soluzioni sostanzialmente e formalmente assimilative. Azioni ad exemplum di tipo specifico con assimilazione sostanziale, ma non formale, c…
I diritti dei consumatori dopo la Direttiva 2011/83/UE
2013
Il saggio offre una disamina critica dei contenuti della Direttiva 2011/83/UE, anche in rapporto agli obiettivi annunciati nella Proposta ( e poi abbandonati), soffermandosi particolarmente sulle regole in tema di obblighi di informazione al consumatore.Alla luce di queste regole, la nuova Direttiva si rivela quale ulteriore significativa conferma della scelta che affida l'obiettivo della trasparenza contrattuale a rigide prescrizioni di forma e contenuto dell'informazione, lungo un processo che qui viene definito di "standardizzazione" delle condotte del professionista. L'obiettivo di disclosure viene affidato non a tecniche di controllo e verifica del concreto livello di informazione offe…
Lifestyle counseling to reduce body weight and cardiometabolic risk factors among truck and bus drivers – a randomized controlled trial
2015
Objectives We conducted a randomized trial among overweight long-distance drivers to study the effects of structured lifestyle counseling on body weight and cardiometabolic risk factors. Methods Men with waist circumference > 100 cm were randomized into a lifestyle counseling (LIFE, N=55) and a reference (REF, N=58) group. The LIFE group participated in monthly counseling on nutrition, physical activity, and sleep for 12 months aiming at 10% weight loss. After 12 months, the REF group participated in 3-month counseling. Assessments took place at 0, 12, and 24 months. Between-group differences in changes were analyzed by generalized linear modeling. Metabolic risk (Z score) was calculated fr…
