Wireless and mobile communication networks critically affect almost every aspect of modern economic (e.g., electronic commerce), political (e.g., elections) and social life (e.g., contemporary social networks), i.e., our culture.
In the context of this course we address mobile and wireless networks, such as cellular, ad hoc, wireless sensor networks (WSN). We study their fundamental characteristics together with issues related to their efficient design with emphasis on algorithmic aspects of topology control and efficient management of critical resources (such as energy and frequency spectrum). We present applications and effects of mobile and wireless networks in cultural heritage management. We study and review modern mobile technologies placing emphasis on the design and development of mobile web and augmented reality applications.

This course is taught as a core course of the the Applications and Foundations of Computer Science direction, during the first semester of the Postgraduate Programme «Computer Science and Technology», at the Computer Engineering and Informatics Dept, University of Patras. The subjects of the course are the mechanisms and technologies used to provide (guaranteed) Quality of service in computer networks.

Development of training material in digital form. The course is related to the creation of undergraduate and postgraduate courses and includes notes, presentations, videotaped lectures, educational software, online exercises, presentation of experiments etc. The aim of the project is this material to become available via Creative Commons license through the institutional platform of the University of Patras to members of the academic community and the wider society.

IOANNIS HATZILYGEROUDIS  Undergraduate 
(A)
COMPUTER ENGINEERING AND INFORMATICS DEPARTMENT, University of Patras
The course consists of the following main topics: functional programming language Lisp, solving problems using Lisp, rulebased programming, intelligent rulebased systems, development of Intelligent Systems, Programming Environment CLIPS. Also, it provides students the opportunity to acquire skills in theoretical and practical issues on implementation of Intelligent Systems using intelligent programming tools.

Course description
The course aims to furnish students with a comprehensive knowledge of the literary comic and its subversive potentials, as well as to develop skills relevant to postgraduate studies. The course therefore concentrates on four core concepts: satire, irony, parody, humor, which constitute basic writing tools and, at the same time, theoretical issues with philosophical implications.
In addition to the knowledge and skills specific to the field of the Comic and the Poetics of Subversion, the course will investigate relevant terms, such as burlesque, pastiche, grotesque, caricature, allegory, quotation, related to the four main terms in many different ways.
The course is so designed to give students an overview of developments within the theoretical field, from the Early Modern Period to today. Within such a chronological framework, the course introduces students to the ways satire, irony, humor and parody have been transformed and to the social and historical conditions under which specific works of literature were created.
Students are introduced to critical and theoretical texts and debates which surround primary texts of the course, thereby being allowed to place their own interpretations within a proper academic context and to understand the developments in critical thinking surrounding a text and within critical theory in general. Different theoretical models are applied to a wide range of European and mainly Greek literary texts

Discrete Mathematics
Evi Papaioannou  Undergraduate 
(A)
Department of Cultural Heritage Management and New Technologies, University of Patras
The course is an introduction to discrete mathematics, a branch of mathematics which aims at counting discrete objects like, for instance, pixels on a screen, characters in a password, directions on how to drive from one place to another.
Despite a strong correlation with Computer Science, Discrete Mathematics are used in practice for solving problems from various disciplines (engineering, physical sciences, social sciences, economics, operations research) and are essential for decision making in non continuous situations.
Emphasis is placed on basic concepts of combinatorics (like combinations, permutations, distribution of objects, subsets, etc.) as well as on the principle of inclusion and exclusion so that students acquire the necessary background and skills for using Discrete Mathematics efficiently in practice for addressing a variety of issues relevant to the Management of Cultural Heritage, with or without the support of New Technologies.
Does a curriculum in Cultural Heritage Management and New Technologies really need to include Discrete Maths? To get the answer just consider the “No” replies to the question: which of the tasks below you can handle? The more the “No” replies, the more intense the necessity of the course...
• You are given 5 Greek, 7 English and 10 Spanish books. In how many ways you can chose 2 of them?
• How many 7character words (no character repetition allowed) you can generate using the Greek alphabet?
• In how many ways you can schedule the exam of 3 courses in 5 days so that no 2 courses are scheduled on the same day?
• In an ancient text, a 3digit date is detected but only the first digit is a clear “1”; the next two digits are not recognizable. What is the range of dates that you should further investigate for your study?
• There are 10 collections available in a museum. In how many ways you can organize a visit including 3 of them?

Digital Signal Processing is concerned with the representation, transformation and manipulation of signals on a computer. After half a century advances, DSP has become an important field, and has penetrated a wide range of application systems, such as consumer electronics, digital communications, medical imaging to name a few. Applications of signal processing include some of the hottest current technology trends: internet of things (IoT), cloud computing, softwaredefined radios, robotics, autonomous vehicles, etc. We are also starting to see higher levels of performance and reduced computational requirements by combining DSP and machine learning techniques.
