Managing large repositories of natural language requirements
No full textAn increasing number of market and technology driven software development companies face the challenge of managing an enormous amount of requirements written in natural language. As requirements arrive at high pace, the requirements repository easily deteriorates, impeding customer feedback and wellfounded decisions for future product releases. In this chapter we introduce a linguistic engineering approach in support of large-scale requirements management.
We present three case studies, encompassing different requirements management processes, where our approach has been evaluated. We also discuss the role of natural language requirements and present a survey of research aimed at giving support in the engineering and management of natural language requirements
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Matematik i köket
No full textProblem: Allt fler elever har svårigheter inom de matematiska målen enligt media. Skolverket anser dock att
svenska elever inte försämrats utan stannat upp i sin förbättringsprocess till skillnad från andra länders elever
som gått ikapp de svenska barnen. Kan praktisk matematik i form av matlagning hjälpa barnen till en bättre
förståelse.
Syfte
Syftet med denna uppsats är att undersöka om det projekt jag beskrivit kan skapa ett intresse samt ökar en
förståelse hos eleverna beträffande matematiken. Jag vill även se om det finns någon märkbar skillnad hos
eleverna gällande dessa två frågor på grund av genus. Jag vill även undersöka om lärarna på skolan anser att
elevernas förståelse påverkats genom projektet samt om pedagogerna ser samarbetet som positivt.
Frågeställningar
1) Ändras elevernas inställning till matematik genom praktik som att laga mat eller baka? På vilket sätt?
) Anser eleverna att projektet med praktisk matematik höjt deras förståelse för matematik ?
3) Går det att tyda någon skillnad i de ovanstående frågorna ur ett genusperspektiv?
4) Hur har lärarna ansett att projektet har fungerat, beträffande samarbetet?
5) Anser lärarna att projektet med praktisk matematik höjer förståelsen för matematik hos eleverna och i så fall
på vilket sätt?
Metod, material & design
Ett kumulativt arbete med en sociokulturell experimentell studie som analyseras genom en kvalitativ &
Kvantitativ undersökning. Mitt resultat är i huvudsak grundat på kvantitativa frågeformulär, intervjuer och
observationer.
Resultat
Det går inte att se några stora skillnader i elevernas syn på kunskap pga av kön. Eleverna visade glädje under
lektionerna.
Majoriteten av elever framförde att de hade lärt sig mer under projektet. Den educationistiska lärarrollen
framkommer som väsentlig. Lärarna valde att arbeta separat med projektet, men ansåg att eleverna utvecklats i
positiv riktning
Requirements Engineering: Solutions and Trends
No full textThis last chapter of the book describes solutions and trends in the discipline of RE. Starting from a wrap-up of what was presented throughout this book, it suggests a framework of requirements engineering and indicates what current solutions are available in this framework. Beyond providing a short overview of the state of the practice, this chapter also summarizes current trends in RE. Four trends are evaluated, namely the growing usage of commercial off-the-shelf components and systems and how RE activities need to be adjusted; the evolving focus on product lifecycle management and the need to collaborate amongst very heterogeneous communities; the wish to learn and to share experiences on effective ways to implement RE in an organization and the growing interest in requirements engineers’ skill sets. We finally provide an outlook into where requirements engineering is heading for

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
A 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C
No full text Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.
