This paper studies how to design the spectrum of a UWB signal in accordance with the FCC regulations and IEEE 802.15.3a recommendations. We show that the "conventional" UWB system with pulse-position modulation and time-hopping multiple access gives rise to spectral lines that violate the regulations. The impact of different modulation and multiple access schemes on the spectrum shaping is derived

A capillary filling microfluidic proteomic sample processing system has been realized in an automated set-up. Chip-integrated solid-phase extraction is performed in a 96-array format followed by sequential capillary action elution into a piezoelectric microdispenser and subsequent transfer to MALDI targets. Samples are eluted and deposited in volumes of 200–300 nl. The robotic system offers calibr

Popular Abstract in Swedish I denna avhandling analyseras ett samverkansprojekt i den så kallade ungdomsvården i Sverige. Projektet hade som mål att förbättra samordningen mellan socialtjänsten och Statens institutionsstyrelse för att kunna effektivisera insatserna för samhällsomhändertagna ungdomar och deras familjer. I projektet var också ett antal samordnare anställda. Det övergripande syftetIn this dissertation a collaboration project in Swedish youth care is analysed. The aim of the project was to enhance coordination between the Social Services and the Swedish National Board of Institutional Care in order to make the efforts more efficient. The project also employed a number of coordinators. The overall purpose of this dissertation is to analyse conflicts, alliances and compariso

OBJECTIVE:: To evaluate the effect of prednisolone and valacyclovir on ipsilateral pain around the ear and in the face or neck in Bell's palsy. The incidence and intensity of pain during the first 2 months of palsy and its prognostic value were also assessed. STUDY DESIGN:: Prospective, randomized, double-blind, placebo-controlled, multicenter trial. SETTING:: Sixteen tertiary referral centers in

The aim of this paper to draw attention to several aspects of the algebraic dependence in algebras. The article starts with discussions of the algebraic dependence problem in commutative algebras. Then the Burchnall-Chaundy construction for proving algebraic dependence and obtaining the corresponding algebraic curves for commuting differential operators in the Heisenberg algebra is reviewed. Next

A frequency synthesizer applied to a 10/100Base-T ethernet transceiver is described. It can work adaptively in either a 10Mbps or 100Mbps mode and convert freely from on mode to another. Cascode current sources and differential delay cells are adopted to guarantee good performance. The circuit meets the requirements of both transmitter on rising/falling time and receiver on CDR so that additional

There existed a great ambivalence concerning masculinity and its relationship to religion in the decades around the last turn of the century. The historical encoding process of religion, from gender neutral to feminine, have in general been interpreted as something solely negative for the constitution of masculinity during this period. Consequently, religious encoded masculinities have been deemed

This article is based on the author’s inaugural lecture as professor of New Testament studies at Lund University and articulates his view of the hermeneutics of text and history by reference to the notion of memory. The old veneration of Mnēmosynē and her daughters Clio and Polyhymnia indicates the close and yet complex relationship between historical truth and persuasion and points to the decisiv

Cognitive semantics relates linguistic expressions to conceptual structures. The purpose of this paper is to present a framework for such a cognitive structure. As a preparation, Putnam's argument against intensional semantics as a theory of meaning is presented. Some of the main tenets of cognitive semantics as it has developed during the last years are outlined. The notion of a conceptual space

Hemiparasitic plants accumulate nutrients in their leaves and therefore produce high-quality litter with faster decomposition and nutrient release rates compared to non-parasitic litter. Higher levels of plant-available nitrogen (N) in the presence of hemiparasitic plants have been attributed to this 'litter effect', but effects on N dynamics in the soil remain unstudied. We tested the hypothesis
