This paper presents a low band antenna impedance tuner in 130nm CMOS-SOI technology. It consists of three digitally controlled switched capacitor banks and two off-chip inductors and is intended for use in terminals supporting modern cellular standards like WCDMA and LTE. By using a negative gate bias in the off state, linearity can be improved and maintained. Measurements show an OIP3 exceeding +
Measurement noise generates undesired control activity resulting in wear of actuators and reduced performance. The effects of measurement noise can be alleviated by filtering the measurement signal. New criteria based on the trade-offs between performance,robustness,and attenuation of measurement noise are proposed for assessment of the design. Simple rules for calculating the filter time constant
The loss of longitudinal connectivity in regulated rivers, both up- and downstream, has been detrimental for biodiversity worldwide. While progress has been made regarding upstream fish passage solutions, many questions remain unanswered regarding downstream passage alternatives. To address these knowledge gaps, we used Atlantic salmon (S. salar) smolts to experimentally assess the guidance effici
“It is with great pleasure that I present to you Fluiten in het Donker, a publication conceived alongside the eponymous group exhibition held at de Appel arts centre, Amsterdam, from May 20th to June 26th, 2011.This book is not stricto sensu an exhibition catalogue. You will not find any explanation or straightforward analysis of the artworks included in the show but instead a constellation of ima
In voltage- and temperature-biased coherent conductors quantum screening effects occur if the conductor's transmission is energy dependent. Here, we show that an additional ac-driven terminal can act as a probe for a direct readout of such effects, hitherto unexplored. We find that screening of charges induced by the static biases impacts already their standard linear thermoelectric response coeff
Appreciation and production of musical rhythm is a human universal and, as with other human capacities, it is imperative to understand the extent of our capacity to perceive and produce rhythm. This thesis presents my work on the cognitive and perceptual aspects of rhythm perception and production at a slow tempi. In Paper I I establish that rhythm production, such as keeping the beat to a metron
E-waste is one of the fastest growing waste streams today and considered a significant developmental challenge with less than 30% of e-waste being formally recycled. High-income countries are at an increasing rate exporting their hazardous waste onto low- and middle-income countries, creating additional pressure, exacerbating health risks, and degrading local environments in countries with less ca

Polymerer är naturliga eller syntetiska makromolekyler som är uppbyggda av flera repeterande enheter, monomerer. I blocksampolymerer är de ingående typerna av monomerer fördelade i olika block i polymeren, t.ex. A och B. Blocksampolymerer är ett intressant forskningsområde med möjliga tillämpningar inom bland annat läkemedelstransport, så kallad controlled drug release, d.v.s för kontrollerad frisIn the present work, the formation of complex coacervate micelles and aggregates of the oppositely charged diblock copolymers poly(N-isopropylacrylamide)27-b-poly((3-acrylamidopropyl)trimethylammoniumchloride)15 [PNIPAAM27-b-PAMPTMA15(+)] and poly(N-isopropylacrylamide)27-b-poly(2-acrylamido-2-methyl-1-propanesulfonic sodium)15 [PNIPAAM27-b-PAMPS15(-)] in aqueous solution have been studied at diff
Through discourse analysis I investigate how the Swedish liberal party, Folkpartiet, constructs two opposing identities in their discourse of alienation (in Swedish utanförskap). I draw from Torben Bech Dyrbergs theory on how identities are constructed through the logics of difference and equivalence (1997). Laclau and Mouffe are the main inspirations for analyzing the organization of the discours
In Chonyonyo, a village in north-west Tanzania, the majority of the population have no access to the groundwater beneath them. Every day, women and children walk several hours to a hole shared with animals, to collect contaminated drinking water for their families’ domestic needs. This report shows that the groundwater resources in the area are sufficient to supply the people of Chonyonyo with fre
Follow-up survey on legal status of information society service providers in the post-CDSM Directive era in Sweden, focusing on service providers as intermediaries and as users of copyright-protected content (March 2022). Phase 2 report, part of ReCreating Europe project WP6 - Intermediaries.
Placing concrete using a truck-mounted pump is a common construction method, enabling pouring of large volumes of concrete in a highly efficient way. However, the method is associated with unfavorable working conditions due to the need for manual handling of the end-hose. The hose-man are exposed to hazardous and poor working conditions.
