Studieneingangstests und Studienerfolg. Mögliche Zusammenhänge am Beispiel zweier Hochschulen

Tests zu Studienbeginn werden an vielen Hochschulen durchgeführt, um die mathematischen Fähigkeiten der Studienanfänger zu ermitteln. Am Beispiel der Daten von der Universität Kassel und der Fachhochschule Aachen werden Einflüsse von Vorkursen und Zusammenhänge der Ergebnisse von Studieneingangstests und Mathematikklausuren der ersten Semester untersucht. Es zeigt sich ein durchaus unterschiedliches Bild – in Abhängigkeit der konkreten Rahmenbedingungen

Stepping further the isolated Roman settlements heritage, ISTER tackles the territorial dimension of the Roman Routes, as a contiguous transnational element that passes national borders acreoss the Danube region and provides a relevant scale for exchange and joint development. Therefore, ISTER’s main objective focuses on rediscovering and revitalizing the ancient Roman Roads Network along the Danube river as a key driver in promoting territorial development based on sustainable use of cultural and natural heritage. During the project, data from all local and regional partners were collected, sorted and harmonised. Based on a user requirements survey, a strategy for the deployment of the ISTER Interactive Tool was developed. The interactive tool uses the collected data and geodata for an open orientation and information platform which aims to foster knowledge about the Roman cultural heritage in the broad public. The ISTER Interactive Tool is set up as a responsive website to be used with mobile devices like smartphones or tablets. The central element of the interactive tool is a map, all information is queried from a central database as location-based service. The tool does not only provide information about the cultural heritage elements (monuments, milestones), but also provides other information which can be useful when planning a trip, like places to eat or drink, accommodation facilities, public transport stops, or supermarkets. It is available not only in English, but also in the local languages of the ISTER project partners

Privacy-Preserving Multi-Party Reconciliation Secure in the Malicious Model (Extended version)

The problem of fair and privacy-preserving ordered set reconciliation arises in a variety of applications like auctions, e-voting, and appointment reconciliation. While several multi-party protocols have been proposed that solve this problem in the semi-honest model, there are no multi-party protocols that are secure in the malicious model so far. In this paper, we close this gap. Our newly proposed protocols are shown to be secure in the malicious model based on a variety of novel non-interactive zero-knowledge-proofs. We describe the implementation of our protocols and evaluate their performance in comparison to protocols solving the problem in the semi-honest case

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV
