Current passive RFID systems face the challenges to locate mobile objects in real time in indoor environments, including the realization of low delay as well as effective cooperation among readers and accurate ranging ability in the physical layer. In order to overcome these challenges, this paper presents a low delay multi-reader passive RFID system using ultra high frequency (UHF) radio as the f
In a masterly book, Roderick MacFarquhar and Michael Schoenhals explain why Mao launched the Cultural Revolution, and show his Machiavellian role in masterminding it (which Chinese publications conceal). In often horrifying detail, they document the Hobbesian state that ensued. The movement veered out of control and terror paralyzed the country. Power struggles raged among Lin Biao, Zhou Enlai, De
Popular Abstract in Swedish Jorden i vår natur är en mycket komplex miljö som innehåller en mängd olika organismer. Bland dessa är bakterier och svampar av störst betydelse eftersom de står för en stor del av nedbrytningen av olika ämnen. Jordbakterierna utför t.ex. många av ämnesomvandlingarna av kväve, svavel och fosfor i marken. Nedbrytningen frigör näringsämnen som sedan kan utnyttjas av växteThe soil bacterial community is under the constant influence of its environment. Changing any of the factors affecting the bacterial community will induce a selection pressure which, with time, will change the community. In this work the effect of changing the temperature or pH on the soil bacterial community was studied. Measurements using the [3H]-thymidine incorporation technique showed that th

This thesis has synchronization of Multicarrier systems, more specifically Orthogonal Frequency Division Multiplexing (OFDM) systems, as the main theme. The thesis addresses two areas, the first proposing and analyzing time and frequency estimators for OFDM systems, the second investigating more practical issues around these estimators. The practical part addresses implementation and applies the e
This volume presents research that relates decision making to creativity with a focus on the social context in which these processes occur. Social and creative aspects have, to some extent, been neglected in previous behavioral decision research. The chapters complement research that have been presented under different headings such as ’naturalistic decision making’, ’distributed decision making’,
Popular Abstract in Swedish Urininkontinens utgör ett stort socialt problem, framför allt hos den äldre befolkningen. Kliniskt är urininkontinens iakttaget i större omfattning hos kvinnor än hos män, men studier antyder männen är mer drabbade än vad nuvarande statistik gör gällande. Grundat på symptombild kan urininkontinens indelas i trängningsinkontinens, ansträngningsinkontinens samt överrinninNormal urine storage and bladder emptying are controlled by the central (CNS) as well as the peripheral nervous system. Dysfunction of these mechanisms can lead to urinary incontinence. Urinary tract dysfunctions have symptomatically been treated mainly with drugs acting peripherally. However, in the CNS, drug targets for pharmacological intervention may be found. The present study deals with effe
