Defect reports are generated from various testing and development activities in software engineering. Some-times two reports are submitted that describe the same problem, leading to duplicate reports. These reports are mostly written in structured natural language, and as such, it is hard to compare two reports for similarity with formal methods. In order to identify duplicates, we investigate usi
Non-radiative decay of core excitations at the B 1s and N 1s absorption edges of bulk hexagonal boron nitride (h-BN) has been studied with resonant Auger spectroscopy. In order to reproduce the bulk properties of the sample while keeping it electrically conducting, we have grown reasonably thick (more than 20nm) polycrystalline films of h-BN on a Ni(111) surface by thermal cracking of borazine vap
We use a 2-dimensional (2-D) Vernier gated-ring-oscillator (GRO) time-to-digital-converter (TDC) in a cascade structure (MASH), so that a larger raw quantization step can be allowed without sacrificing the final resolution performance. The 2-D approach effectively reduces the latency time under a large input, while the MASH structure provides a 2nd-order noise shaping that produces a lower in-band
We present a dynamical study of the double parton distribution in impact parameter space, which enters into the double scattering cross section in hadronic collisions. This distribution is analogous to the generalized parton densities in momentum space. We use the Lund Dipole Cascade model, presented in earlier articles, which is based on BFKL evolution including essential higher order corrections
One of the main drivers of China’s e-commerce boom is the dramatic expansion of the country’s Internet finance industry, which has grown and diversified at a staggering rate over the past decade. The emergence of Chinese Internet finance has been discussed in largely positive terms as facilitating commercial activity. It has also been linked to the wider developmental goal of promoting financial i
Partially premixed combustion is a compression ignited combustion strategy where high exhaust gas recirculation (EGR) levels in combination with early or late injection timing result in a prolonged ignition delay yielding a more premixed charge than with conventional diesel combustion. With this concept it is possible to get low smoke and NOx emissions simultaneously. Accurate control of injection
Popular Abstract in Swedish Detta är en studie om Willy Brandt och Berlinfrågan. Berlinfrågan kom att symbolisera en stor del av Brandts politiska gärning och med den som utgångspunkt belyses och analyseras hans politiska livsverk. Med hjälp av en semantisk metod undersöker författaren hur Brandts politiska språk är uppbyggt och redovisar hur hans argumentation ser ut. Tyngdpunkten i studien är enWilly Brandt is one of the most important charismatic leaders of the postwar era and his Ostpolitik is considered his great political achievement. The Berlin Question can be said to symbolize his political activities. Therefore, by concentrating on this issue I can explore and analyse his political thinking as a whole. My basic assumption in this dissertation is that a politician tends to stick to
The globalization of English in Sweden is examined as it takes shape in educational policy and practice. Following in the tradition of a “new wave” of language policy and planning research that emphasizes connections between policy and how it is interpreted by local stakeholders, this investigation focuses on textual data from Swedish national curricular documents and observational data of preserv
This work presents a digital calibration technique in continuous-time (CT) ΔΣ analog to digital (A/D) converters. The converter is clocked at 144MHz with a low oversampling ratio (OSR) of only 8. Dynamic element matching (DEM) is not efficient to linearize the digital to analog converter (DAC) when the OSR is very low. Therefore, non-idealities in the outermost multi-bit feedback DAC are measured
We carry out bipolar Monte Carlo (MC) simulations of electron and hole transport in a multi-quantum well light-emitting diode with an electron-blocking layer. The MC simulation accounts for the most important interband recombination and intraband scattering processes and solves self-consistently for the non-quasiequilibrium transport. The fully bipolar MC simulator results in better convergence th
The focus of this paper is on investigating the influence of skewing on the torque production of an Interior Permanent Magnet Synchronous Machine (IPMSM). The machine is designed as a traction machine according to the requirements of a parallel hybrid electric commercial heavy vehicle. In order to meet the requirements, the machine is designed with a speed higher than that of the conventional powe
The dissertation analyzes a recognized collective political actor in Egypt, the shabāb al-thawra – the revolutionary youth. The thesis posits that in order to understand the shabāb al-thawra political actor, it is necessary problematize “revolutionary youth” beyond its nominative sense. Instead, the concepts of “youth” and “revolutionary” are conceived as communities of practice, whereby “youth” r
The traditional view of asthma has changed considerably during the last decades. A paradigm shift in our understanding of asthma has turned our focus from the importance of muscle spasm to inflammation. Today asthma is believed to be a central airway inflammatory disorder, and the importance of activated eosinophils found in central airway biopsies and in induced sputum is believed to be a hallmar
Background: Several attempts to increase the locoregional control in locally advanced lung cancer including concurrent chemotherapy, accelerated fractionation and dose escalation have been made during the last years. As the EGFR directed antibody cetuximab has shown activity concurrent with radiotherapy in squamous cell carcinoma of the head and neck, as well as in stage IV NSCLC combined with che
