Reasoning & Querying – State of the Art

Various query languages for Web and Semantic Web data, both for practical use and as an area of research in the scientific community, have emerged in recent years. At the same time, the broad adoption of the internet where keyword search is used in many applications, e.g. search engines, has familiarized casual users with using keyword queries to retrieve information on the internet. Unlike this easy-to-use querying, traditional query languages require knowledge of the language itself as well as of the data to be queried. Keyword-based query languages for XML and RDF bridge the gap between the two, aiming at enabling simple querying of semi-structured data, which is relevant e.g. in the context of the emerging Semantic Web. This article presents an overview of the field of keyword querying for XML and RDF

A Survey of Techniques for Improving Security of GPUs

Graphics processing unit (GPU), although a powerful performance-booster, also has many security vulnerabilities. Due to these, the GPU can act as a safe-haven for stealthy malware and the weakest `link' in the security `chain'. In this paper, we present a survey of techniques for analyzing and improving GPU security. We classify the works on key attributes to highlight their similarities and differences. More than informing users and researchers about GPU security techniques, this survey aims to increase their awareness about GPU security vulnerabilities and potential countermeasures

Large Scale Data Analytics with Language Integrated Query

Databases can easily reach petabytes (1,048,576 gigabytes) in scale. A system to enable users to efficiently retrieve or query data from multiple databases simultaneously is needed. This research introduces a new, cloud-based query framework, designed and built using Language Integrated Query, to query existing data sources without the need to integrate or restructure existing databases. Protein data obtained through the query framework proves its feasibility and cost effectiveness

A Software Application for Colleges of Education Students Results Processing

Most educational institutions in Nigeria, such as the Universities, Polytechnics and Colleges of Education still operate on the manual method of record keeping and computation of students’ grade point averages (GPA) which is time-consuming and error prone especially when the number of students is large. This paper examines the inadequacies involved in the manual method of calculating Students CGPA (cumulative grade point average) and proposes a solution by developing a software Application to facilitate the automated processing of the results. The software was developed using PHP (Hypertext processor) scripting language and employing MYSQL Relational Database Management System in designing the database. The developed software was tested and found to performed well and produced expected results on completion. With it, it was possible to compute Grade Point Average (GPA) and Cumulative Grade Point Average (CGPA) for each student based on examination scores entered. The new system has some qualities such as reduction in the cost of processing of information, reduction in time spent in computing GPA and generating transcripts, increase in accuracy and efficiency, and elimination of duplication of effort which makes it superior to the manual system of student record keeping. This new system is flexible and can be modified to suit any kind of student’s record keeping and data processing. Keywords: Examination Scores, Automated Processing, Cumulative Grade Point Average, Software Application, Results Grading, Database

How to Create an Innovation Accelerator

Too many policy failures are fundamentally failures of knowledge. This has become particularly apparent during the recent financial and economic crisis, which is questioning the validity of mainstream scholarly paradigms. We propose to pursue a multi-disciplinary approach and to establish new institutional settings which remove or reduce obstacles impeding efficient knowledge creation. We provided suggestions on (i) how to modernize and improve the academic publication system, and (ii) how to support scientific coordination, communication, and co-creation in large-scale multi-disciplinary projects. Both constitute important elements of what we envision to be a novel ICT infrastructure called "Innovation Accelerator" or "Knowledge Accelerator".Comment: 32 pages, Visioneer White Paper, see http://www.visioneer.ethz.c

Advantages of low-code in Intranet Portals: Enhancing the visualization of internal data in a major retail chain through low-code applications

Internship Report presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Information Systems and Technologies ManagementLIDL, a major multinational retail chain with branches spread across the globe, has many internal processes that aren’t centralized. In each country branch, information is dispersed within several platforms, in different formats, which in turn makes data harder to analyze, slowing down procedures that are frequently used within each division of the major retail chain. With this problem in mind LIDL has decided to invest in Low-Code, giving the liberty to each country to develop its own internal portal to counter this problem. With this, each branch centralizes all its essential information in one place. By choosing low-code, LIDL has given each country the freedom of developing the necessary applications in record time, providing a way to experience omnichannel experiences without giant budgets and costly development teams. The results of this study show why portal development should be done with Low-Code, the synergy that is built between the two concepts and the many advantages that follow. To defend these claims, the work done during my internship will be showcased and analyzed
