Sparsity Preserving Computation for Spectral Projectors
(Amer Inst Physics, 2011)Several areas of applications such as model order reduction preconditioner design and eigenvalue problems for spectral projectors can be found in the literature. In this paper a fast and sparsity preserving approach for ... -
A sparsity-preserving spectral preconditioner for power flow analysis
(TUBITAK Scientific & Technical Research Council Turkey, 2016)Due to the ever-increasing demand for more detailed and accurate power system simulations the dimensions of mathematical models increase. Although the traditional direct linear equation solvers based on LU factorization ... -
A spectral divide and conquer method based preconditioner design for power flow analysis
(2010)Power system simulations most of the time require solution of a large sparse linear system. Traditional methods such as LU decomposition based direct methods are not suitable for parallelization in general. Thus Krylov ... -
Strategic Early Warning System for the French milk market: A graph theoretical approach to foresee volatility
(Elsevier, 2017)This paper presents a new approach for developing a Strategic Early Warning System aiming to better detect and interpret weak signals. We chose the milk market as a case study in line with the recent call from the EU ... -

(Int Business Information Management Assoc-IBIMA, 2012)Corporate social responsibility (CSR) refers to companies that voluntarily go beyond what the law requires in order to achieve social and environmental objectives during the course of their daily business activities. The ... -
Sustainable Knowledge Management Shown In The Example of a Company Operating On The Telecommunications Market
(Elsevier Science Bv, 2015)Modern organizations are being strongly pressured to increase agility and competitiveness operate on the global market and engage in alliances. One key success factor for these organizations is the human factor. Human ... -
A Sustainable Multi-Layered Open Data Processing Model For Agriculture: IoT Based Case Study Using Semantic Web For Hazelnut Fields
(ASTES Publishers, 2020)In recent years, several projects which are supported by information and communications technologies (ICT) have been developed in the agricultural domain to promote more precise agricultural activities. These projects ... -
Tablets as primary educational computing devices. An impact analysis on the educational landscape in an Austrian university.
(Elsevier Science, 2014)In this study we analyze how tablet devices could be used as educational tools to support innovative educational practice in a university in Austria. Students and educators were issued tablet devices in 2011 across the ... -
Towards Faster Branch Outage Simulations Using Simulated Annealing and Parallel Programming
(IEEE, 2009)Contingency studies such as branch outage and generator outage are among important studies of energy management centers operations. Branch outage modeling on the other hand is one of the basic steps of post-outage state ... -
Trends in social media application: The potential of Google+ for education shown in the example of a bachelor's degree course on marketing
(Springer, 2011)Google Plus has the potential to improve students' collaboration through circles conduct research for projects with sparks improve the student-instructor relationship by using this kind of social media to get in touch with ... -
