Irreducible restriction and zeros of characters
2000
Let G be a finite group, let N be normal in G and suppose that X is an irreducible complex character of G. Then XN is not irreducible if and only if X vanishes on some coset of N in G.
Finite groups with real-valued irreducible characters of prime degree
2008
Abstract In this paper we describe the structure of finite groups whose real-valued nonlinear irreducible characters have all prime degree. The more general situation in which the real-valued irreducible characters of a finite group have all squarefree degree is also considered.
Research of a Cellular Automaton Simulating Logic Gates by Evolutionary Algorithms
2003
This paper presents a method of using genetic programming to seek new cellular automata that perform computational tasks. Two genetic algorithms are used : the first one discovers a rule supporting gliders and the second one modifies this rule in such a way that some components appear allowing it to simulate logic gates. The results show that the genetic programming is a promising tool for the search of cellular automata with specific behaviors, and thus can prove to be decisive for discovering new automata supporting universal computation.
When the arts inspire businesses: Museums as a heritage redefinition tool of brands
2018
International audience; While the literature has mainly considered brand museums as communication tools or complex retail environments, this article analyses them through a heritage framework and suggests that brands can use heritage technologies of the arts for their own purposes. The case study of the brand museum of the Laughing Cow highlights the heritage technologies the brand uses to endorse two heritage roles: an inter-generational memory role based on the transmission of the brand's history and a community representation role through spaces and objects. As a consequence, this research sheds light on how brands can come to be accepted as heritage objects. By using heritage technologi…
SmartCampus Project
2017
The aim of the SmartCampus project is to create an environment which enables high-quality, flexible and effective studying, both as traditional face-to-face and online. A focal result of the project is the CiNetCampus environment, developed in connection with the Master’s education in mathematical information technology. It increase flexibility in education with the help of video lectures and add interactivity to lecture videos. It was also possible to integrate other functionalities to the environment that are useful for teaching and studying. This paper focuses on the presentation of the CiNetCampus environment and the functionalities implemented for it. The paper also highlights the impa…
Modeling Requirements for Future CASE
1995
In this paper we discuss some requirements for future CASE Computer Aided Software/Systems Engineering environments. These requirements include increased modifiability and flexibility as well as support for process and agent models. We claim that they can only be addressed by developing more powerful representation and modeling techniques. As a possible basis for modeling various techniques, we outline a general information architecture for a future CASE environment. In addition, we propose primitive types for specifying techniques, the development process, and agent models, and use these types for modeling an example methodology and examine how the requirements are or can be supported in o…
Existence and uniqueness of solutions to superdifferential equations
1993
Abstract We state and prove the theorem of existence and uniqueness of solutions to ordinary superdifferential equations on supermanifolds. It is shown that any supervector field, X = X0 + X1, has a unique integral flow, Г: R 1¦1 x (M, AM) → (M, AM), satisfying a given initial condition. A necessary and sufficient condition for this integral flow to yield an R 1¦1-action is obtained: the homogeneous components, X0, and, X1, of the given field must define a Lie superalgebra of dimension (1, 1). The supergroup structure on R 1¦1, however, has to be specified: there are three non-isomorphic Lie supergroup structures on R 1¦1, all of which have addition as the group operation in the underlying …

Ventricular Fibrillation and Tachycardia Detection Using Features Derived from Topological Data Analysis
2022
A rapid and accurate detection of ventricular arrhythmias is essential to take appropriate therapeutic actions when cardiac arrhythmias occur. Furthermore, the accurate discrimination between arrhythmias is also important, provided that the required shocking therapy would not be the same. In this work, the main novelty is the use of the mathematical method known as Topological Data Analysis (TDA) to generate new types of features which can contribute to the improvement of the detection and classification performance of cardiac arrhythmias such as Ventricular Fibrillation (VF) and Ventricular Tachycardia (VT). The electrocardiographic (ECG) signals used for this evaluation were obtained from…
On Human–Computer Interaction in Brain–Computer Interfaces
2014
In this chapter, theoretical reflections on human–computer interaction in brain–computer interfaces (BCIs) are combined with the results of an empirical investigation concerning non-invasive EEG-based BCI users’ experiences with this technology. After a short overview of transhumanist visions in the field of neurotechnology this text discusses some anthropological positions concerning interaction between man and technical devices. The focus will be on the concept of “transparency”. Then some empirical results of a pilot study which investigated BCI users’ experiences concerning human–computer interaction in BCI use are presented and discussed against the anthropological background.
