Evolutionary changes applied to a framework API may invalidate existing framework-based applications. While manually adapting applications is expensive and error-prone, automatic adaptation demands cumbersome specifications, which the developers are reluctant to write and maintain. Considering structural changes (so-called refactorings) of framework APIs, our adaptation technology supports backward-compatible framework upgrade. The technology is rigorous defining precisely the structure and automatic derivation of compensating adapters. It is also practical compensating for most application-breaking API changes automatically, while requiring neither manual adaptation nor recompilation of existing application code.

LHCb is a high-precision experiment for the study of CP violation and rare decays in B physics. It has two Ring Imaging Cherenkov (RICH) counters for particle identification. The RICH system uses Hybrid Photon Detectors (HPD) for single photon detection. This thesis describes tests performed on individual HPDs for quantum efficiency and vacuum quality. It then presents work done monitoring HPD vacuum quality through regular ion feedback measurements after they were mounted into the RICH. Also discussed is HPD vacuum degradation and how replacement and repair of deteriorated HPDs was implemented using data from the vacuum monitoring. Preparations for an upgrade to LHCb have started. The upgrade will extend the discovery potential of the LHCb by increasing the rate of data collection. This thesis presents particle identification and avour tagging studies using upgrade simulations. Flavour tagging using kaons was then reoptimised for upgrade conditions and this work is described with discussions of the results.

Bakgrund och problemdiskussion: Efterfrågan på en mer harmoniserad redovisnings- lagstiftning på grund av ökad globalisering och mer fria gränser ledde fram till införandet av IFRS, som implementerades år 2005. IFRS är obligatoriskt för noterade bolag i Sverige, men även onoterade bolag kan välja att frivilligt tillämpa IFRS. K-regelverket infördes i sin helhet år 2014 och sedan dess har större onoterade bolag möjligheten att frivilligt uppgradera sin redovisningsstandard från K3 till IFRS. Syfte: Uppsatsens syfte är att identifiera vilka faktorer som bidrar till att bolag väljer att frivilligt uppgradera sin redovisningsstandard. Metod: Uppsatsen består av två delstudier. Den första delstudien är en kvantitativ studie med en deduktiv forskningsansats och den andra delstudien är en kvalitativ studie med en abduktiv forskningsansats. Att kombinera de två delstudierna möjliggör identifiering av faktorer som studeras genom data från årsredovisningar och utifrån en intervjuserie med ekonomi- eller redovisningsansvariga på åtta bolag. Resultat och slutsatser: Studiens resultat tyder på att det finns vissa faktorer som påverkar bolag att frivilligt uppgradera sin redovisningsstandard. Den första delstudiens resultat visar att storlek och bransch har en påverkan på bolag att frivilligt uppgradera sin redovisningsstandard. Delstudie två visar att flera av första delstudiens faktorer i kombination påverkar bolagens förhållande till att frivilligt uppgradera sin redovisningsstandard, men även att ägarnas preferenser och riskbenägenhet är avgörande. / Background and problem diskussion: The demand for a more harmonized accounting legislation due to increased globalization and more free borders led to the introduction of IFRS, which was implemented in 2005. IFRS are mandatory for listed companies in Sweden, but also unlisted companies may choose to voluntarily adopt IFRS. The K- regulatory framework was introduced in its entirety in 2014 and since then larger unlisted companies has the opportunity to voluntarily upgrade their accounting standard from K3 to IFRS. Purpose: This paper aims to identify the factors contributing to why companies choose to voluntarily upgrade their accounting standard. Method: The thesis consists of two studies. The first study is a quantitative study with a deductive research approach and the second study is a qualitative study with an abductive research approach. Combining the two sub-studies allow identification of factors studied through data from annual reports and factors through a series of interviews with finance or accounting officers of eight companies. Results and conclusions: The study's results suggest that there are certain factors that affect the companies to voluntarily upgrade their accounting standard. The results from the first part of the study show that the size and industry have an impact on companies to voluntarily upgrade their accounting standard. Part two of the study shows that factors from the first part of the study in combination with each other affect companies to voluntarily upgrade their accounting standard, but also that owners' preferences and willingness to take risks is crucial.

Business Process Management (BPM) is a relatively new development paradigm that takes a high-level approach to coding by leveraging a graphical, “flow chart” aesthetic that allows users to assemble modular tasks into a larger process. The resulting diagrams effectively enshrine the organizations processes into an executable model that provides an objective and transparent view of the process and the activities contained within. In doing so, BPM models serve as both a system to guide employees through proper business procedures as well as documentation of the businesses processes. Similar to most other software development environments, BPM development platforms possess several features intended to address the needs of code versioning, dependency management and impact assessment. However, due to the unique way that development is done in BPM platforms, the more traditional functionality of these features sometimes renders them ineffective and ill suited to the task of BPM development. Changes to lower level reusable components in these BPM models can result in impacts to diverse processes across an organization that are difficult to predict and onerous to locate. There is much room for improvement in BPM development tools. This thesis proposes a new framework for dependency management and impact assessment to improve the usability, effectiveness and efficiency. The framework is composed of a Business Process Component Architecture, a Dependency Data Model and an Upgrade Algorithm which are all used to provide increased visibility over dependent processes and superior guidance during upgrade operations. Several example case scenarios are be used to evaluate our proposed framework. The cases represent progressive degrees of complexity to test the capabilities and robustness of the framework. Overall, the framework was able to appropriately handle the case examples used and showed promise in terms of providing practical effort, time and cost savings for BPM developers. The framework can also provide developers assistance in locating circular dependencies, but is subject to the same limitations as developers when attempting to upgrade these relationships.

Semileptonic B decays of the type Bq⁰→Dq⁻μ⁺ν (where Dq⁻→K⁻K⁺pie⁻) are selected and their lifetimes are corrected using a statistical simulation-based correction called the k-factor. Using 1 fb⁻¹ of LHCb data the B⁰ and Bs⁰ mixing frequencies are measured to be Deltamd = ( 0.503 ± 0.011 (stat) ± 0.013 (syst) ) ps⁻¹ and Deltams = ( 17.93 ± 0.22 (stat) ± 0.15 (syst) ) ps⁻¹. We exclude the null hypothesis of no mixing for the B⁰ and Bs⁰ by 5.8 and 13.0 standard deviations respectively. This is the first observation of Bs Bsbar mixing using only semileptonic B decays. The lepton flavour violating decay D⁰→eμ is searched for, using tagged D⁰ decays from D*→D⁰pie, and the measurement is normalised using D⁰→K⁻pie⁺ decays. No evidence is seen of an excess over the expected background and so a limit is placed B(D⁰→eμ) < 1.3×10⁻⁸ at a 90% confidence level using 3 fb⁻¹ of LHCb data. This improves the previous measurement by a factor of 20 and is the world's best measurement. Possible upgrades to the LHCb VELO detector are simulated and aspects of the upgraded detector are optimised to ensure that all tracks within the angular acceptance can be detected with high precision. Finally the simulated performance of the current and upgraded VELO detectors are compared.

Abstract Taiwan¡¦s economy has progressed along with the industrial development. Various scales of industrial development districts had begun their way since the 60¡¦s and Feng Shang Industrial District (FSID) was among the examples at that time. However, following the time and location changes, earlier developed infrastructure of FSID had deteriorated and has been unable to maintain its functions. Similar to the needs confronting with the industrial economy, FSID is also required to change in the structure and upgrade their technology in order to maintain its function and fulfill the pressing requirement of environmental protection and sustainment. The purpose of the study is to analyze the current problems confronting with FSID and its development in the future in order to come up with the possibility of upgraded industry and transformation. Through the analysis of an in-depth focused group interview, it was found that FSID can progress in two directions. One direction is to release the current organization and re-develop its planning of land. The other direction is to upgrade FSID¡¦s technology into an industry with higher profit. Regardless of which directions FSID would take, they should fulfill the requirement in low pollution and be environmental concerned.

This thesis presents an electrical model of two pairs of interconnects of the ATLAS Phase-1 Upgrade Hadronic Endcap Front End Crate prototype baseplane. Stripline transmission lines of the baseplane are modeled using Keysight Technologies' Electromagnetic Professional's (EMPro) 3D electromagnetic simulation (Finite Element Method) and the connectors are modeled using built-in models in Keysight Technologies' Advanced Design System (ADS). The model is compared in both the time and frequency domain to measured Time Domain Reflectometer (TDR) traces and S-parameters. The S-parameters of the model are found to be within 5% of the measured S-parameters for transmission and reflection, and range from 25% below to 100% above for forward and backward crosstalk. To make comparisons with measurements, the cables used to connect the prototype HEC baseplane to the measurement system had to be included in the model. Plots of the S-parameters of a model without these cables are presented for one pair of interconnects for which the crosstalk is expected to be the higher than most other interconnects of the baseplane. / Graduate / 0605 / 0798 / rdporter@uvic.ca

Syftet med denna uppsats är att beskriva användarnas upplevda nytta/upplevelse av ett affärssystem som företaget använder. Vidare redogörs för de eventuella svårigheter företaget stött på vid uppgradering av affärssystemet. Studien har utgått ifrån en kvalitativ undersökning och en deduktiv ansats. Genom semistrukturerade intervjuer med ett urval på sex respondenter i ett fastighetsbolag skapades en empiri. De valda respondenterna arbetar på olika avdelningar och har olika positioner i företaget, detta för att kunna ge en helhetsbild av företaget till studien. Företagets affärssystem är ett verksamhetsanpassat affärssystem, som företaget är nöjda med. Det finns för- och nackdelar med ett sådant system, där en av nackdelarna som respondenterna nämner är att det är kostsamt. Det är kostsamt framförallt vid uppgradering av affärssystemet, då det tar mycket tid att utföra och att företaget är i stort behov av konsulter. Behovet av konsulter finns för att kunna uppgradera systemet, samt när problem uppstår med systemet. Något annat som kostar är interna och externa utbildningar. Det företaget gör är att ta in konsulter för att utbilda sina anställda istället för att skicka anställda på utbildning. Anledningen till att konsulter tas in av företaget är för att fler anställda tar del av utbildningen vid en internutbildning, vilket leder till en mindre kostnad för företaget. / The purpose of this essay is to describe the users' perceived benefits / experience of an ERP system that the company uses. Furthermore, outlines the possible difficulties the company encountered when upgrading the ERP system. The study has been based on a qualitative study and a deductive approach. Through semi-structured interviews with a sample of six respondents in a property company created an empiricist. The selected respondents are working in different departments and with different positions in the company, this in order to give an overall picture of the company in to the study. The system of the company is an activity suited ERP and the company is pleased with. There are advantages and disadvantages of such system, where one of the disadvantages that the respondents mention is that it is costly. It is costly, especially when upgrading the business system, in which it takes much time and that the company is in great need of consultants. The need for consultants is in order to upgrade the system, as well as problems arise within the system. Something else that costs is internal and external training programs. What the company doe’s, is to bring in consultants to train their employees. The reason that the consultants are brought in by the company is that more employee’s takes part of the training during an internal, which leads to a lower cost to the company.
