Computer Science at FU • Working Groups – – – Algorithms in Bioinformatics Education Computer Science at FU • Working Groups – – – Algorithms in Bioinformatics Education and Society Databases and Information Systems IT-Sicherheit Artificial Intelligence Mathematical Basics Medical Infomatics Networkbased Informationsystems Programming Languages and Computer Architecture Software Engineering and System Software Computer Systems and Telematics Theoretical Computer Science

Algorithms in Bioinformatics is Development and Application of Methods and Tools of Computer Science Algorithms in Bioinformatics is Development and Application of Methods and Tools of Computer Science on biological issues ? ? ? e. g. Interpretation of Mass-spectrometrically Measuring data for Protein regulation

Algorithms in Bioinformatics At the interface of Biology/Chemistry/Medicine/ Computer Science and Mathematics • Concrete Algorithms in Bioinformatics At the interface of Biology/Chemistry/Medicine/ Computer Science and Mathematics • Concrete Questions: • Pattern Matching in Blood count • Similarities of Humans and Mice (and Dogs and …) • Develop Algorithms, which are able to scan Terabyte f Data fast.

Education and Society How is Computer Science concerned with Education and Society? • It Education and Society How is Computer Science concerned with Education and Society? • It needs good teachers for school subject Computer Science. These are studying Didactics here and get to know new Methods of Teaching • It supports Living and Learning, e. g. by means of internet • If affects the Society, e. g. by many new professions and computer support at work.

New teaching Methods • Pupils from Japan and Deutschland are learning together via E-Mail, New teaching Methods • Pupils from Japan and Deutschland are learning together via E-Mail, Internet and Video-Meetings

Databases and Informationsystems Applications: • Public Transport (find train connections), • Airlines (book Tickets), Databases and Informationsystems Applications: • Public Transport (find train connections), • Airlines (book Tickets), • Online-Shops (buy Books and CDs), • Search engines (e. g. Google), • File-Sharing (mp 3 on Gnutella, Ka. Za. A) An Example: Saving Videos and searcing for Scenes Find all Musicvideos with Eminem Find all Scenes with Sunset

Artificial Intelligence The research on the subject of artificial intelligence deals with problems, which Artificial Intelligence The research on the subject of artificial intelligence deals with problems, which are hard to solve for a computer, although they can be easily solved by humans (because humans profit of the benefits of intelligence) Examples: Face Recognition Speech Recognition Agility

Robotics: AI with mechanic body Interdisciplinary: Mechanic is of need, as well as elektronic, Robotics: AI with mechanic body Interdisciplinary: Mechanic is of need, as well as elektronic, computer science and the right communication. Concrete questions: • How does a robot recognize Objects on the field? • Which is the ideal route he should take? • Which actions shall the robot perform?

Programing Languages • There are various kinds of Programs: – Programs prescripe the way Programing Languages • There are various kinds of Programs: – Programs prescripe the way how to perform calculations. – A variety of programs can be formed by concatenation of computer instructions. – Programs are parts of huge EDV-Systems. • Programs are written using programming languages. There are various kinds of programming languages, each focused on another range of problems. • Programming is mathematically exacting. • Programming is an engineers job.

Programming Languages (Part 2) • How can programs get created more efficiently and secure Programming Languages (Part 2) • How can programs get created more efficiently and secure ? • How can one avoid coding errors, or how can they be found automatically ? • How may properties of programs get verified ? • Which tools takes it to simplify the process of programming ?

Software Technics and System Software How do I build a big software system out Software Technics and System Software How do I build a big software system out of existing components – without having to add too much ? What kind of languages, methods and tools can be provided by the computer science, for the reason of simplifieing the development of software for connected Computers ? How could structur and functionality of complex systems get explained using visualising techniques and animation ?

Software Technics involve • systematic approach of • structured development • complex software systems Software Technics involve • systematic approach of • structured development • complex software systems - jenseits der „Programmierung im Kleinen“ Quality of Software and quality assurance Software Architecture: How can big systems get well structured? Modelling and Specification: How can software development get planned precisly structuring before implementing? Construction of secure Systems: Showing no weak spots! Software Visualising and –animation: Visibility!
