It grew out of the early West Slavic settlement of ''Misni'' inhabited by Glomatians and was founded as a German town by King Henry the Fowler in 929. In 968, the Diocese of Meissen was founded, and Meissen became the episcopal see of a bishop. The Catholic bishopric was suppressed in 1581 after ...

Acatech
Acatech (styled ''acatech),'' founded in 2002 and established as the German Academy of Science and Engineering (german: Deutsche Akademie der Technikwissenschaften) on 1 January 2008, represents the interests of German technical sciences independently, in self-determination and guided by the common good, at home and abroad. acatech is organized as a working academy that advises politicians and the public on forward-looking issues concerning the technical sciences and technology politics. The academy sees itself as an institution that provides neutral, fact and science-based assessments of technology-related questions and serves society with far-sighted recommendations of excellent quality. Also, acatech aims to facilitate the knowledge transfer between science and business and to promote new talent in the technical sciences. To further the acceptance of technical progress in Germany and demonstrate the potential of forward-looking technologies for the economy and for society, acate ...

Academic Staff Of The University Of Potsdam
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

OpenHPI (Online Education)
openHPI is a platform for massive open online courses ( MOOC) in the field of computer science and information technology. It is hosted at the Hasso Plattner Institute (HPI) in Potsdam, Germany. openHPI is open to everyone, and participation is free of charge. Everybody can register and enroll for courses without any prerequisites. openHPI's courses are derived from HPI's bachelor and master programs in IT-Systems Engineering and cover both, foundations of information technology as well as highly topical innovations. The course languages are English and German. openHPI offers around six to ten courses per year. All courses follow the same educational format: The subject domain is split into two to six weekly units. Each week, video lectures, reading materials and quizzes are presented in a learning sequence. Learners can ask their questions and discuss points of interest with each other in the course discussion forum which is actively moderated by the teaching team. Learning prog ...

MOOC
A massive open online course (MOOC ) or an open online course is an online course aimed at unlimited participation and open access via the Web. In addition to traditional course materials, such as filmed lectures, readings, and problem sets, many MOOCs provide interactive courses with user forums or social media discussions to support community interactions among students, professors, and teaching assistants (TAs), as well as immediate feedback to quick quizzes and assignments. MOOCs are a widely researched development in distance education, first introduced in 2008, that emerged as a popular mode of learning in 2012, a year called the "Year of the MOOC". Early MOOCs (cMOOCs: Connectivist MOOCs) often emphasized open-access features, such as open licensing of content, structure and learning goals, to promote the reuse and remixing of resources. Some later MOOCs (xMOOCs: extended MOOCs) use closed licenses for their course materials while maintaining free access for students. ...

Tele-TASK
Tele-TASK is a university research project in the e-learning area. It can be applied to lecture recording, post-processing and distribution. Research topics include e-learning, tele-teaching, semantic web, video analysis, speech recognition, collaborative learning, social networking, web technologies, recommendation systems, statistics and video codecs and conversion. The project was founded by Christoph Meinel and his research group at the University of Trier. When he accepted the chair for Internet Technologies and Systems at Hasso Plattner Institute at the University of Potsdam/Germany, the tele-TASK project also moved with him. Reference software was developed as proof of concept, such as an online e-lecture archive a lecture recording Lecture recording refers to the process of recording and archiving the content of a lecture, conference, or seminar.

Binary Decision Diagram
In computer science, a binary decision diagram (BDD) or branching program is a data structure that is used to represent a Boolean function. On a more abstract level, BDDs can be considered as a compressed representation of sets or relations. Unlike other compressed representations, operations are performed directly on the compressed representation, i.e. without decompression. Similar data structures include negation normal form (NNF), Zhegalkin polynomials, and propositional directed acyclic graphs (PDAG). Definition A Boolean function can be represented as a rooted, directed, acyclic graph, which consists of several (decision) nodes and two terminal nodes. The two terminal nodes are labeled 0 (FALSE) and 1 (TRUE). Each (decision) node u is labeled by a Boolean variable x_i and has two child nodes called low child and high child. The edge from node u to a low (or high) child represents an assignment of the value FALSE (or TRUE, respectively) to variable x_i. Such a BDD is ca ...

Computational Complexity Theory
In theoretical computer science and mathematics, computational complexity theory focuses on classifying computational problems according to their resource usage, and relating these classes to each other. A computational problem is a task solved by a computer. A computation problem is solvable by mechanical application of mathematical steps, such as an algorithm. A problem is regarded as inherently difficult if its solution requires significant resources, whatever the algorithm used. The theory formalizes this intuition, by introducing mathematical models of computation to study these problems and quantifying their computational complexity, i.e., the amount of resources needed to solve them, such as time and storage. Other measures of complexity are also used, such as the amount of communication (used in communication complexity), the number of gates in a circuit (used in circuit complexity) and the number of processors (used in parallel computing). One of the roles of computationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
