Sizing of Dual-V-T Gates for Sub-V-T Circuits

This paper presents a novel method to improve the performance of sub-threshold (sub-V-T) gates in 65-nm CMOS technology. Faster transistors with a lower threshold voltage are introduced in the weaker network of a gate. It is shown that the employed method significantly enhances the reliability and performance of the gate, with an additive advantage of a lower area cost compared to traditional tran

Sverige - EEC och konkurrensen: aspekter på Sveriges frihandelsavtal med EEC med särskild tonvikt på avtalets konkurrensregler

Sveriges frihandelsavtal med EEC. En genomgång av avtalens mål medel och administration. Hur ska bestämmelserna tolkas mot bakgrund av bl.a. Wienkonventionen om Traktaträtten. Praktiska implikationer granskas med särskild tonvikt på avtalets konkurrensregler liksom hur dessa är kopplade till utvecklingen av konkurrensrätten i den Europeiska Ekonomiska Gemenskapen. Kan avtalet förväntas få en direk

Chloride Penetration into concrete: Proceedings of the International RILEM Workshop

"Chloride penetration into concrete is one of the most decisive processes for durability and service-life of concrete structures. Design for durability of new structures, and maintenance and repair of existing structures, requires a correct understanding and quantification of the processes involved. Throughout the world, much work has been done and is going on, but still we cannot predict the pe

Structural Studies Of Materials Using Time-Resolved X-ray Diffraction

This work consisted of the application of X-ray diffraction methods to the study of ultrafast phenomena in various materials. Since the X-ray pulses generated from the bending magnet at the MAX II ring, where most of the experimental work was conducted, have a duration of the order of 300 ps, they can not be used directly as probe pulses in experiments where higher temporal resolution is required.

A genetic component to resistance to fungal infection in frog embryos

The embryo has traditionally been considered to completely rely upon parental strategies to prevent threats to survival posed by predators and pathogens, such as fungi. However, recent evidence suggests that embryos may have hitherto neglected abilities to counter pathogens. Using artificial fertilization, we show that among-family variation in the number of Saprolegnia-infected eggs and embryos i

Spatio-Temporal Estimation for Mixture Models and Gaussian Markov Random Fields - Applications to Video Analysis and Environmental Modelling

In this thesis computationally intensive methods are used to estimate models and to make inference for large, spatio-temporal data sets. The thesis is divided into two parts: the first two papers are concerned with video analysis, while the last three papers model and investigate environmental data from the Sahel area in northern Africa. In the first part of the thesis, mixture models are used to

Knowing and the Art of IT Management. An inquiry into work practices in one-stop shops

Popular Abstract in Swedish Informationsteknologin utvecklas i allt snabbare takt. Däremot tycks utvecklingen ske långsammare när det gäller de modeller, metaforer och metoder som används för att beskriva och förstå hur information sprids och hanteras i organisationer, i kommuner och i samhället i stort. Använder vi egentligen IT på ett effektivt sätt i det dagliga arbetet? I den här avhandlingen New information technology is developing faster than the models, metaphors and methods in use for conceptualizing the sharing and managing of information in organizations, in communities and in society in general. The way we utilize information technology today does not seem to succeed in supporting the everyday work practices through which organizations accomplish their work. In this Ph.D. disser

Clinical evaluation of an adjustable cerebrospinal fluid shunt valve

Popular Abstract in Swedish Operationer för att dränera vätska från hjärnans hålrum för att sänka ett högt tryck i skallen är den mest förekommande operationstypen vid neurokirurgiska kliniken i Lund. Orsaken till det höga trycket är oftast hydrocefalus (vattenskalle p.g.a. för mycket hjärnvätska), antingen som följd av en medfödd missbildning eller som följd av en förvärvad åkomma. Ytterligare orIntroduction: Shunting systems are implanted for draining cerebrospinal fluid to treat hydrocephalus, intracranial cysts, and idiopathic intracranial hypertension. Most shunt systems include a valve which regulates drainage. A differential pressure valve opens when intracranial pressure exceeds the valve’s opening pressure. The difficulty with these valves is selecting and predicting the most sui

Processing of raw Cassava (Manihot esculenta) - Experiments and Modelling.

The objective of the present thesis was to understand how the quality and performance of dried cassava products could be developed by drying and other processing steps. This goal was achieved in several stages. First, a survey of the composition of six cassava varieties from Bolivia, was performed, which resulted in the report of chemical and mineral compositions of the tubers. The mineral composi
