On the Lifecycle Management of Standards

Popular Abstract in Swedish Globala internationella standards har stort inflyttande i var nutida teknikorienterade värld. Exemplen är många: vi kan importera och exportera produkter och tjänster i de flesta andra länder, vi kan kommunicera med andra personer var de än befinner sig, vi kan även resa snabbt och effektivt. Men skapande och underhåll av internationella standarder är ingen enkel procesStandards are used everywhere in the modern world and are a fundamental part of a functioning society. But the creation and maintenance of international standards is not an easy task. In addition to the technical prerequisites that must exist to create a standard, there are also political, economic and cultural aspects that must be considered. The present thesis does not interpret all these aspec

Self-consistent GW0 results for the electron gas: Fixed screened potential W0 within the random-phase approximation

With the aim of properly understanding the basis for and the utility of many-body perturbation theory as applied to extended metallic systems, we have calculated the electronic self-energy of the homogeneous electron gas within the GW approximation. The calculation has been carried out in a self-consistent way; i.e., the one-electron Green function obtained from Dyson’s equation is the same as tha

Neuropsychiatric background factors to violent crime

Introduction and aims. Mental disorders among perpetrators of violent and sexual crimes differ from those in the general population in prevalence, course, and patterns of comorbidity. The Göteborg Forensic Neuropsychiatry Projects was initiated to map neuropsychiatric vulnerability factors (disorders, deficits, symptoms, and neurobiological aberrations) among violent offenders and analyze the find

Medicinsk fysik

Medicinsk fysik är ett ämnesövergripande läromedel, som ger en inblick i modern medicinsk diagnostik och terapi med strålning, områden i ständig utveckling. Boken beskriver och förklarar olika strålningsfysikaliska tillämpningar och hur fysiken gör det möjligt att framställa medicinska bilder.

Generalization of the duration-time concept for interpreting state of the art high resolution resonant photoemission spectra

The duration-time concept, vastly successful for interpreting the frequency dependence of resonant radiative and nonradiative x-ray scattering spectra, is tested for fine-scale features that can be obtained with state of the art high-resolution spectroscopy. For that purpose resonant photoelectron (RPE) spectra of the first three outermost singly ionized valence states X 2Σg+, A 2Πu, and B 2Σu+, a

An Integrated Framework for the Design and Optimization of SOC Test Solutions

We propose an integrated framework for the design of SOC test solutions, which includes a set of algorithms for early design space exploration as well as extensive optimization for the final solution. The framework deals with test scheduling, test access mechanism design, test sets selection, and test resource placement. Our approach minimizes the test application time and the cost of the test acc

HCCI Operation of a Multi-Cylinder Engine

A six-cylinder truck-size engine has been converted for Homogeneous Charge Compression Ignition (HCCI) operation. This work demonstrates that it is possible to run a multi-cylinder engine under HCCI operation. The ultra-low NOX characteristic of HCCI is also demonstrated. The sensitivity of combustion timing with respect to operating parameters is investigated, and a closed-loop control system is

Structure Functions and Final-State Properties in Deeply Inelastic electron-proton Scattering

Popular Abstract in Swedish Hur ser det ut inuti protonen? Vi vet att protonen består av mindre partiklar. Den utgörs egentligen av tre st. kvarkar, men där finns också en mängd gluoner och virtuella kvarkar och antikvarkar. Gluonerna är de partiklar som håller ihop de tre kvarkarna (valenskvarkarna) i ett så hårt grepp att protonen blir väldigt liten (ca. 100000 ggr mindre än en atom). Det är deIn this thesis, we give a description of the detailed structure of the proton and a description of the final-state properties in electron-proton scattering. Qualitative results, in a purely gluonic scenario with the leading log approximation, and quantitative results, where quarks are included and some sub-leading corrections have been made, are presented. The quantitative results are in fair agre

Polymer Displacement and Supermacroporous Cryogels - Two New Tools in Chromatographic Separation of Biomolecules and Bioparticles

Production of protein is often accompanied with difficulties due to the large amounts of different biological material resulting from fermentation. This makes purification necessary and affinity chromatography is usually involved as being biospecific, although suffering from limitations as low recovery due to ineffective elution and inability to handle particulate materials. Displacement of lactat

Social Militarisation and the Power of History. A Study of Scholarly Perspectives

In this book, three historical macro-regions are analysed: East Asia, Southeast Asia and Mesoamerica. By comparing three very different historiographical patterns from the specific point of view of social militarisation, we gain an outsider's perspective that proves to be very illuminating. Due to structural features of the various scholarly arenas the three regions turn out very differently. Some
