Visualizing wiki author contributions in higher educationArias Torres, Cristina G 11 1900 (has links)
This thesis investigates how users contribute to wiki environments implemented in higher education settings. The type, extent and quality of users' edits is assessed by analyzing a student-generated wiki through a manual analysis carried by three raters. This project aims to present the relative contribution of wiki users as a way to motivate them to collaborate in a wiki-based group project. Manual as well as automatic programs are used to analyze the same set of wiki articles. Automatic algorithms are proposed to estimate users' relative contribution and ownership to the article. Suggested is the implementation of a visual representation known as a glyph (working as an add-on to the wiki) that shows statistics on participants contributions. Several glyph designs were tested by participants through interviews. These interviews showed that participants identified the visualization as a motivation enhancer to contribute to wikis.

ICT Security of an Electronic Health Record System: an Empirical Investigation : An in depth investigation of ICT security in a modern healthcare system / ICT-säkerhet inom vårdsystem:en empirisk undersökningKvastad, Johan January 2016 (has links)
An empirical investigation of the security flaws and features of an in-use modern electronic health record system is performed. The investigation was carried out using dynamic analysis, manual testing and interviews with developers. The results indicate that in-use electronic health record systems suffer from serious authentication flaws, arising from the interaction of many different proprietary systems. The authentication problems are so severe that gaining access to any user’s computer on the hospital intranet would compromise a large database of patient medical records, including radiological data regarding the patients. Common web vulnerabilities were also present, such as injections and incorrectly configured HTTP security headers. These vulnerabilities were heavily mitigated by the use of libraries for constructing web interfaces. / En empirisk undersökning av säkerheten inom ett modernt elektroniskt patientjournal-system har utförts. Undersökningen genomfördes med hjälp av dynamisk analys, manuell testning och intervjuer med utvecklarna. Resultatet indikerar att system för elektroniska patientjournaler har stora brister inom autentisering, vilka uppstår p.g.a. att flera olika kommersiella system måste samarbeta. Problemen är så allvarliga att med tillgång till en enda dator på intranätet kan en stor databas med patientdata äventyras, inklusive radiologisk data gällande patienterna. Vanliga websårbarheter fanns också, så som injektioner av skript och inkorrekt konfigurerade HTTP säkerhetsheaders. Dessa sårbarheter mitigerades starkt genom användandet av bibliotek för webinterface.

Automated Identification of Adverbial Clauses in Child Language SamplesClark, Jessica Celeste 10 March 2009 (has links) (PDF)
In recent years, computer software has been used to assist in the analysis of clinical language samples. However, this software has been unable to accurately identify complex syntactic structures such as adverbial clauses. Complex structures, including the adverbial clause, are of interest in child language due to differences in the development of this structure between children with and without language impairment. The present study investigated the accuracy of new software, called Cx, in identifying adverbial clauses. Two separate collections of language samples were used. One collection included 10 children with language impairment, 10 age-matched peers, and 10 language-matched peers. A second collection contained language from 174 students in first grade, third grade, fifth grade, and junior college. There was high total agreement between computerized and manual analysis with an overall Kappa level of .895.

Analýza závad na DPS pomocí X-RAY / Analysis of Defects on PCB Using X-RAYMlýnek, Martin January 2015 (has links)
This thesis is focused on BGA packages and fault detection after rework using X – Ray. There is a description of BGA packages by carrier substrate, techniques of connecting on chip, from mounting packages to repair printed circuit boards (hereafter PCB). Thesis summarizes description of defects, which are created after rework process. There is also description of X – Ray as method for analyzing defects. X – PLANE method used to detect internal structure of BGA packages and it was confirmed by microsection and by software for reconstruction. Description of automatic and manual measurement is follow.
