Distributed Recognition of Reference Nodes for Wireless Sensor Network Localization

All known localization techniques for wireless sensor and ad-hoc networks require certain set of reference nodes being used for position estimation. The anchor-free techniques in contrast to anchor-based do not require reference nodes called anchors to be placed in the network area before localization operation itself, but they can establish own reference coordinate system to be used for the relative position estimation. We observed that contemporary anchor-free localization algorithms achieve a low localization error, but dissipate significant energy reserves during the recognition of reference nodes used for the position estimation. Therefore, we have proposed the optimized anchor-free localization algorithm referred to as BRL (Boundary Recognition aided Localization), which achieves a low localization error and mainly reduces the communication cost of the reference nodes recognition phase. The proposed BRL algorithm was investigated throughout the extensive simulations on the database of networks with the different number of nodes and densities and was compared in terms of communication cost and localization error with the known related algorithms such as AFL and CRP. Through the extensive simulations we have observed network conditions where novel BRL algorithm excels in comparison with the state of art

Impact assessment for the twenty-first century–rising to the challenge

The future of impact assessment has to contend with global megatrends, including the Fourth Industrial Revolution, that are set to change the face of the planet, and with the neoliberal economy, and the implications this has for trade-offs in decision-making under the umbrella of ‘sustainable development’. Together these challenges have implications for human health and well-being, and biodiversity. In this letter, we set out these challenges, before moving onto the solutions that are needed to rise to them. These include: formalising technology assessment processes and/or the inclusion of emerging technologies within the scope of legislated IA processes; a move towards legislated substantive outcomes, rather than enforcement of procedure only; and ensuring that the framing of IA goals are based on societal definitions of sustainability

Strafferettssystemets håndtering av personer med pedofilidiagnose som begår seksuallovbrudd mot barn: En rettsempirisk og tverrfaglig systemanalyse

Denne masteroppgaven inntar et "systemperspektiv" for å undersøke hvordan personer med pedofilidiagnose (pedofil forstyrrelse) håndteres i strafferettssystemet. Fenomenet pedofili er oppgavens omdreiningspunkt, og undersøkes i relasjon til flere ulike regler og vurderinger innenfor strafferettssystemet (skyldevne, straffeutmåling, reaksjonsvalg og særregler under straffegjennomføring). Oppgavens tilnærming kan omtales som en rettsempirisk og tverrfaglig systemanalyse, der én ambisjon er å bringe innsikt om fenomenet pedofili fra psykologi og psykiatri inn i jussen.Masteroppgave (60 sp)JUS396MAJU

Biskupi zwolennicy orzeczeń soboru w Nicei na Wschodzie po synodzie mediolańskim w 355 roku na podstawie korespondencji Lucyferiusza z Calaris

In extant correspondence of Lucifer of Calaris, have been discussed the problems related to difficulties with which, some of the bishops and their communities have had to faced in times of the Arians major influence in the Roman Empire and as well as issues of efforts made to improve their conditions. Source base of presented text represent the letter of Pope Liberius and two letters of St. Athanasius. This article states not only the elaboration those three of among surviving letters, but also takes into account their translation into polish language

Environmental assessments and sustainable finance taxonomies – a riposte

Seven authors have responded to our paper asking whether the European Union (EU) Taxonomy will change the mindset over the contribution of Impact Assessment (IA) to sustainable development, delivering a range of opinions, based on a number of themes including: the politics of decision-making; the need to achieve positive impacts and strengthen carrying capacities; the transition to a green economy; the lack of clarity over the role of Strategic Environmental Assessment; and past historical experience. To each of these points, we provide a response highlighting why we think the potential for a change of mindset still exists. Ultimately, however, we recognise that a mindset change will not happen passively; it does need the IA community to become more political and engage with the financial community to make it clear what financial benefits their environmental knowledge can deliver

The role of CFTR in bicarbonate secretion by pancreatic duct and airway epithelia

The secretory epithelia of the pancreatic duct and airway share the ability to generate HCO3--rich fluids. They both express CFTR (cystic fibrosis transmembrane conductance regulator) at the apical membrane and both are adversely affected by cystic fibrosis. CFTR is predominantly a Cl- channel, and it is widely believed that HCO3- secretion in the pancreatic duct is mediated mainly by a Cl-/HCO3- exchanger at the apical membrane. Studies on airway epithelia, however, have suggested that CFTR, despite its low permeability to HCO3-, may nonetheless be directly responsible for HCO3- secretion across the apical membrane. This article reviews recent work that has re-examined both of these hypotheses
