Receivers for faster-than-Nyquist signaling with and without turbo equalization

Faster-than-Nyquist (FTN) signaling is a trellis coding method that maintains the error rate while reducing signal bandwidth. The combined effect is to move closer to capacity. We study some basic receiver issues: How to model the signaling efficiently in discrete time, how much the Viterbi receiver can be truncated, and how to combine the method with an outer code. The methods are modeling for mi

Vibration-induced neuropathy in the hand

Popular Abstract in Swedish Vibrationsskador utgör idag ett av de största yrkesmedicinska problemen. Hälften av dem som arbetar med handhållna vibrerande verktyg får besvär från händerna på grund av skador på blodkärl och nerver. Nervskadan yttrar sig som domningar och stickningar i fingrarna med fumlighet och svaghet i handen. Skadan är allvarlig eftersom symptomen kan leda till försämrad handfunThe aim of this study was to investigate clinical, pathophysiological and structural aspects of vibration-induced peripheral neuropathy since work with hand-held vibrating tools may lead to progressive neurological and vascular hand symptoms. Symptomatic vibration-exposed men were examined clinically and by neurography, tactilometry, and vibrometry and by measurement of temperature perception thre

Stability Criteria for Systems with Bounded Uncertain Time-varying Delay

Stability in presence of bounded uncertain time-varying time delays in the feedback loop of a system is studied. The stability problem is treated in the Integral Quadratic Constraint (IQC) framework. The stability criterion is formulated as frequency dependent linear matrix inequalities. The criterion can be equivalently formulated as a Semi-Definite Program (SDP) using Kalman-Yakubovich-Popov lem

The Lebanese Diaspora: The Arab Immigrant Experience in New York, Montreal and Paris

The Lebanese are the largest group of Middle Eastern immigrants in the United States, and Lebanese immigrants are also prominent across Europe and the Americas. Based on over eighty interviews with first-generation Lebanese immigrants in the global cities of New York, Montreal and Paris, this book shows that the Lebanese diasporaolike all diasporasoconstructs global relations connecting and transf

Skriftens ansikten : konsten att läsa mellan raderna

The biblical figures have stimulated the creative imagination of a wide variety of writers and composers during the past two millennia. This study surveys the reception history in poetry, novels, art and music of a number of biblical figures, e.g. Cain, Abel, Abraham, Isaac, Miriam, the poor widow (Mark 12:41-44), Peter, Judas and Barabbas. The book discusses the interpretations of these biblical

On Auxiliary Systems in Commercial Vehicles

Popular Abstract in Swedish Hjälpsystem i tunga fordon (bussar)As more and more focus is put on the environmental questions and the request for cleaner transportation the demand on the vehicles increases. Especially the environmental request of the public transportation that is visible to the public and operates in the centre of the city. The demand on the buses used for public transportation will increase. The whole bus must be optimised, usually only the pr

Mineral element contents in drinking water - aspects on quality and potential links to human health

Popular Abstract in Swedish Mineraler fås från både fast och flytande föda. De senaste årtiondena har bordsvattenkonsumtionen ökat, och vattnets kemiska innehåll har alltmer kommit i fokus. Studier visar dessutom att grönsakers mineralinnehåll har minskat, vilket ökar betydelsen av mineralintag från annat håll. Den här doktorsavhandlingen omfattar fyra olika studier. I den första studien undersökMineral elements in drinking water have been in focus for more than a decade, especially as the habit of drinking bottled water has increased, not the least among young people. Minerals in drinking water have become more important since minerals in food, especially in vegetables, have decreased substantially the last decades. This thesis includes four different studies. In the first study 20 munic

The Definition of Acceptance and Acceptability.

Despite the recognised importance of the concept of acceptance, how and why new technologies are actually accepted by drivers is not well understood. While many studies claim to have measured acceptance, few have defined what it is. The chapter points out the importance of defining acceptance and categorizes the definitions that have been used according to their “essence” and the various dimension
