An activity-based vocabulary for Voice Output Communication Aids (VOCAs) was designed and evaluated through a user-centred, iterative design process, using expressions from the Gothenburg Spoken Language Corpus as well as other recorded, natural conversations. The growth and development of the vocabulary, called Phrases, was closely linked to its evaluation. The iterative design process included p
Service discovery is central in pervasive middleware systems, built on top of the communication substrate using the more fundamental mechanisms for device discovery. In mobile pervasive systems devices come and go, and switch network frequently, demanding support for device discovery across heterogeneous networks. We present the design of a device discovery mechanism for the PalCom middleware that
A pulse of respiration is induced by rewetting dry soil. Here we study the microbial responses underlying this pulse of respiration when rewetting soil dried for 4-days or 1-year. In the 4-days dried soil, respiration increased to a maximum rate immediately upon rewetting after which it decreased exponentially. In the 1-year dried soil, respiration also increased immediately, but then remained hig
The results of a search for an excited bottom-quark b* in pp collisions at root s = 7 TeV, using 4.7 fb(-1) of data collected by the ATLAS detector at the LHC are presented. In the model studied, a single b*-quark is produced through a chromomagnetic interaction and subsequently decays to a W boson and a top quark. The search is performed in the dilepton and lepton + jets final states, which are c
Hypoxic preconditioning is thought to rely on gene products regulated by hypoxia-inducible factor (HIF)-1. Here, we show that the HIF-1 target gene cyclin-dependent kinase inhibitor 1, p21(WAF1/CIP1), is essential for neuroprotection by hypoxic/aglycemic or erythropoietin preconditioning using wild-type and p21(WAF1/CIP1)-deficient neurons. Furthermore, overexpression of wild-type p21(WAF1/CIP1) o
We report the development of a high-level bacterial expression system for the Alzheimer's disease-associated amyloid beta-peptide (A beta), together with a scaleable and inexpensive purification procedure. A beta(1-40) and A beta(1-42) coding sequences together with added ATG codons were cloned directly into a Pet vector to facilitate production of Met-A beta(1-40) and Met-A beta(1-42), referred t
Experimental single-phase, condensation, and evaporation (flow boiling) pressure drop data from the literature and our previous studies were collected to evaluate previous frictional pressure drop correlations for horizontal microfin tubes of different geometries. The modified Ravigururajan and Bergles correlation, by adopting the Churchill model to calculate the smooth-tube friction factor and by
This paper explores a global trend where universities are collaborating with local government, industry and civic organisations to advance the sustainable transformation of a specific town, city or region. With empirical evidence, we argue that this function of ‘cocreation for sustainability’ could be interpreted as the seeds of an emerging, new mission for the university. We demonstrate that this
Climate warming is expected to alter hydropower generation in California through affecting the annual stream-flow regimes and reducing snowpack. On the other hand, increased temperatures are expected to increase hydropower demand for cooling in warm periods while decreasing demand for heating in winter, subsequently altering the annual hydropower pricing patterns. The resulting variations in hydro
Rating scales are increasingly the primary outcome measures in clinical trials. However, clinically meaningful interpretation of such outcomes requires that the scales used satisfy basic requirements (scaling assumptions) within the data. These are rarely tested. The SF-36 is the most widely used patient-reported rating scale. Its scaling assumptions have been challenged in neurological disorders
The management of minor and moderate head trauma in children differs widely between countries. Presently, there are no existing guidelines for management of these children in Scandinavia. The purpose of this study was to produce new evidence-based guidelines for the initial management of head trauma in the paediatric population in Scandinavia. The primary aim was to detect all children in need of
Following the fragmentation of a 550 MeV u(-1)primary beam of Ni-58, time-and energy-correlated gamma decays from isomeric states in neutron-deficient nuclei in the 1f(7/2) shell have been identified using the GSI fragment separator in combination with the RISING Ge-detector array. The results on isomers in the mirror pairs Ti-43(22)21-Sc-43(21)22 (I-pi = 3/2(+) and 19/2(-)), Cr-45(24)21-Sc-45(21)
This doctoral thesis explores the implications of establishing tradable certificate schemes for improving energy efficiency (so-called ‘Tradable White Certificate’ [TWC] schemes). Carrying out different case studies, a set of complementary evaluation methods is applied in conducting ex-ante and ex-post evaluation studies. To analyse the attributes and complexities of TWC schemes, the thesis focuse
We have compared the predictions of ligand-binding affinities from several methods based on end-point molecular dynamics simulations and continuum solvation, i.e. methods related to MM/PBSA (molecular mechanics combined with Poisson-Boltzmann and surface area solvation). Two continuum-solvation models were considered, viz. the Poisson-Boltzmann (PB) and generalised Born (GB) approaches. The non-el
Monitoring of glucose in subcutaneous and brain striatum have been extensively studied in the past. While biocompatibility was one of the limitations, others included the messy measuring equipments preclude monitoring in a complex environment. This study tried to establish an amperometric measurement of glucose in pre- and post-insulin-administration on diabetic and hyperglycemia rats via wireless
This paper investigates the gains harvested through base station cooperation in the up-link for a multi-user (MU) Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system, operating in a real indoor environment. The base stations perform joint detection using an iterative receiver that carries out multi-user detection and channel estimation via soft information
Syftet med denna studie är att analysera hur de involverade aktörerna upplever, definierar och tolkar ett behandlingsprojekt, som involverade samhällsomhändertagna ungdomar. Projektet involverade olika myndigheter vars representanter skulle innefatta en vårdkedja och benämndes Motverka Våld och Gäng (MVG-projektet). I projektet var också ett antal samordnare anställda. Utöver redovisningen av våraThis report concerns a large evaluation of a project concerning Swedish juvenile care. We analyse how professionals, youngsters and parents perceived and interpreted the three-year project which involved different authorities whose representatives should form a care-giving chain. The project also employed a number of coordinators. Beyond accounting for the results from just over one houndred inter
In this paper a fully coupled thermomechanical two-dimensional simulation model for orthogonal cutting is presented. The model is based on the arbitrary Lagrangian-Eulerian formulation with the remeshing technique. The material model used for the workpiece material includes Johnson-Cook plasticity, and as the chip separation criterion the Johnson-Cook damage law is employed. The different friction
Many persons world wide are exposed to cold environments, either indoors for example in cold stores, or outdoors. Cold is a hazard to health and may affect safety and performance of work. Basis for the creation of safe and optimal working conditions may be obtained by the application of relevant international standards. ISO 11079(1)) presents a method for evaluation of whole body heat balance. On
