    Essential written information such as text books, bills, and catalogues needs to be accessible by everyone. However, access is not always available to vision-impaired people. As they require electronic documents to be available in specific formats. In order to address the accessibility issues of electronic documents, this research aims to design an affordable, portable, standalone and simple to use complete reading system that will convert and describe complex components in electronic documents to print disabled users

    According to a World Intellectual Property Organization (WIPO) estimation, only 5% of the world's one million print titles that are published every year are accessible to the approximately 340 million blind, visually impaired or print disabled people. Equal access to information is a basic right of all people. Essen- tial information such as flyers, brochures, event calendars, programs, catalogues and booking information needs to be accessible by everyone. Information helps people to make decisions, be involved in society and live independent lives. Ar- ticle 21, Section 4.2. of the United Nation's Convention on the rights of people with disabilities advocates the right of blind and partially sighted people to take control of their own lives. However, this entitlement is not always available to them without access to information. Today, electronic documents have become pervasive. For vision-impaired people electronic documents need to be available in specific formats to be accessible. If these formats are not made available, vision-impaired people are greatly disadvantaged when compared to the general population. Therefore, addressing electronic document accessibility for them is an extremely important concern. In order to address the accessibility issues of electronic documents, this research aims to design an affordable, portable, stand-alone and simple to use "Complete Reading System" to provide accessible electronic documents to vision impaired

    Development of enabling technologies for single cell analysis with mass spectrometry

    Mass spectrometry (MS) is an effective methodology for untargeted, label-free, highly multiplexed analyses of trace compounds based on their mass-to-charge ratios. For biological applications, these properties have generated interest in determining biomarkers of diseased states, detecting drug compounds and metabolites, and observing previously unknown chemical messengers. Recent developments in instrumentation have provided exquisite sensitivity with robust performance. A growing field of single cell chemical analysis has arisen around these figures of merit. While early reports utilized manual isolation and extraction, recent developments in high-throughput sampling have enabled the examination of large populations of cells. One such method includes the analysis of dispersed single cells on a flat surface. When cells are randomly seeded onto the surface, their locations have to be determined by optical imaging to direct acquisition of isolated cells efficiently. A variety of microprobe ionization sources are suitable for such analyses, though smaller probe footprints can utilize more densely seeded samples. This dissertation describes two technologies for performing single cell analysis with mass spectrometry. The first, synchronized desorption electrospray ionization (DESI), facilitates ambient ionization MS with high mass resolution, low duty cycle mass analyzers. The initial report utilized synchronized DESI for mass spectrometry imaging, but interrupting the desorption plume would be useful for profiling several locations on a surface in an arbitrary order for single cell analysis. The second methodology utilizes microscopy images to guide MS profiling. Specifically, image analysis software, called microMS, was developed to perform cell finding and correlate optical coordinates with the physical coordinates in a mass spectrometer. Since most of the functionality of microMS is decoupled from the mass spectrometer, the workflow can be easily extended to a variety of instruments. Using matrix-assisted laser desorption/ionization (MALDI) time of flight (TOF)-MS, rodent pancreatic islet cells were investigated and heterogeneous peptide processing was detected at the single cell level. With secondary ion mass spectrometry, disparate tissue from the mammalian nervous system was differentiated and further stratified into separate populations. A unique feature of such analyses is that only a fraction of the sample is consumed and the location of a cell is constant once the sample is dried. This property greatly simplifies sequential, follow-up analysis. As an example, MALDI-TOF-MS was utilized to rapidly screen a population of islet cells to select alpha and beta cell types. The locations of those cells were then targeted for liquid microjunction extraction in order to examine their metabolite profiles with capillary electrophoresis-MS. Finally, while microscopy-guided MS profiling is accurate enough to target single cells, the methodology is flexible enough to analyze much larger samples, including tissue sections or bacterial colonies. As an application, natural product mutant libraries were screened directly from E. coli colonies using microMS. The suite of technologies and protocols described increases the applicability of many mass spectrometers to characterize a range of cells, colonies and similar objects for their chemical composition

    Die Bauhaus-Universität Weimar ist seit langer Zeit mit dem Forum Bauinformatik eng verbunden. So wurde die Veranstaltung 1989 hier durch den Arbeitskreis Bauinformatik ins Leben gerufen und auch das 10. und 18. Forum Bauinformatik (1998 bzw. 2006) fand in Weimar statt. In diesem Jahr freuen wir uns daher besonders, das 30. Jubiläum an der Bauhaus-Universität Weimar ausrichten zu dürfen und viele interessierte Wissenschaftler und Wissenschaftlerinnen aus dem Bereich der Bauinformatik in Weimar willkommen zu heißen. Das Forum Bauinformatik hat sich längst zu einem festen Bestandteil der Bauinformatik im deutschsprachigen Raum entwickelt. Dabei steht es traditionsgemäß unter dem Motto „von jungen Forschenden für junge Forschende“, wodurch insbesondere Nachwuchswissenschaftlerinnen und ‑wissenschaftlern die Möglichkeit geboten wird, ihre Forschungsarbeiten zu präsentieren, Problemstellungen fachspezifisch zu diskutieren und sich über den neuesten Stand der Forschung zu informieren. Zudem wird eine ausgezeichnete Gelegenheit geboten, in die wissenschaftliche Gemeinschaft im Bereich der Bauinformatik einzusteigen und Kontakte mit anderen Forschenden zu knüpfen. In diesem Jahr erhielten wir 49 interessante und qualitativ hochwertige Beiträge vor allem in den Themenbereichen Simulation, Modellierung, Informationsverwaltung, Geoinformatik, Structural Health Monitoring, Visualisierung, Verkehrssimulation und Optimierung. Dafür möchten wir uns ganz besonders bei allen Autoren, Co-Autoren und Reviewern bedanken, die durch ihr Engagement das diesjährige Forum Bauinformatik erst möglich gemacht haben. Wir danken zudem Professor Große und Professor Díaz für die Unterstützung bei der Auswahl der Beiträge für die Best Paper Awards. Ein herzliches Dankeschön geht an die Kollegen an der Professur Informatik im Bauwesen der Bauhaus-Universität Weimar für die organisatorische, technische und beratende Unterstützung während der Planung der Veranstaltung

    ENERGY CONSUMPTION OF MOBILE PHONES

    Battery consumption in mobile applications development is a very important aspect and has to be considered by all the developers in their applications. This study will present an analysis of different relevant concepts and parameters that may have an impact on energy consumption of Windows Phone applications. This operating system was chosen because limited research related thereto has been conducted, even though there are related studies for Android and iOS operating systems. Furthermore, another reason is the increasing number of Windows Phone users. The objective of this research is to categorise the energy consumption parameters (e.g. use of one thread or several threads for the same output). The result for each group of experiments will be analysed and a rule will be derived. The set of derived rules will serve as a guide for developers who intend to develop energy efficient Windows Phone applications. For each experiment, one application is created for each concept and the results are presented in two ways; a table and a chart. The table presents the duration of the experiment, the battery consumed in the experiment, the expected battery lifetime, and the energy consumption, while the charts display the energy distribution based on the main threads: UI thread, application thread, and network thread
