A Mathematical Approach to Self-Organized Criticality in Neural Networks
(2008-12-22)Self-organized criticality (SOC) is one of the key concepts to describe the emergence of complexity in natural systems. Recently a candidate for a SOC system has been found in the recordings ... -
A Mayer-Vietoris Spectral Sequence for C*-Algebras and Coarse Geometry
(2019-04-10)Let $A$ be a C*-algebra that is the norm closure $A = \overline{\sum_{\beta \in \alpha} I_\beta}$ of an arbitrary sum of C*-ideals $I_\beta \subseteq A$. We construct a homological spectral sequence that takes as input the ... -
A Multi-Layered Identity and Access Management Solution for Establishment of Scalable Federated Identity
(2023-12-22)Federated identity management (FIM) systems are defined as a group of organizations (entities) that have agreed to establish trust relationships and share identity information to enable seamless access to resources across ... -
A Multi-objective Ant Colony Optimisation-based Routing Approach for Wireless Sensor Networks Incorporating Trust
(2012-08-31)In the near future, Wireless Sensor Networks (WSNs) are expected to play an important role for sensing applications, in the civilian as well as in the military sector. WSNs are autonomous, distributed, self-organised ... -
A new approach to the investigation of Iwasawa invariants
(2015-01-05)Let K be a fixed number field, let p be a prime number, and let Z_p denote the additive group of p-adic integers. The growth of the p-Sylow subgroups of the ideal class groups of the intermediate fields in a Z_p-extension ... -
A Process-Oriented Framework for Security Assessment of Cyber-Physical Systems
(2022-07-28)Due to digitalization and technological advancement, systems and their requirements are changing, and there is an increasing use of Cyber-Physical Systems (CPS) with a direct connection between the physical and the digital ... -
A Secure and Privacy-Friendly IP-based Emergency Services Architecture
(2019-12-20)Emergency services support is one of the most valued features of the public switched telephone network. With the transition to IP-based communication the opportunity to re-design the emergency services communication ... -
A Security Aware Fuzzy Enhanced ACO Routing Protocol in MANETs
(2018-12-20)As Mobile Ad hoc NETworks (MANETs) grow more popular and are deployed as solutions in various applications such as road safety in Vehicular Ad hoc NETworks (VANETs), wildlife tracking in Wireless Sensor Networks (WSNs) and ... -
A Statistical Model of Microscope Resolution
(2020-07-10)A general rule of thumb in imaging is that the resolution of a light microscope depends linearly on the full width at half maximum (FWHM) of its point spread function (psf). In the present work we carefully define a ... -
A Study of VoIP Performance in Anonymous Network - The Onion Routing (Tor)
(2014-06-23)Information technology is developing rapidly, especially in the field of computer science, telecommunications and information systems. In the early days of telecommunications, voice networks could not be combined with data ... -
A theory of discrete parametrized surfaces in R^3
(2018-07-27)In discrete differential geometry (DDG) one considers objects from discrete geometry from a differential geometric perspective. Rather than focusing on approximations of the smooth theory, with error vanishing in the ... -
A UML Based Methodology for the Development of Web Services
(2010-08-06)Web services are currently one of the most important technologies for enabling an effective communication between and within distributed systems. The Web services technology relies on widely ... -
A unified framework for spline estimators
(2013-07-09)This dissertation develops a uni ed framework to study the (asymptotic) properties of all (periodic) spline based estimators, that is of regression, penalized and smoothing splines. The explicit form of the periodic ... -
A Wasserstein-like Distance on Vector Fields
(2023-10-06)We introduce a new distance on the space of vector fields over a Riemannian manifold that is motivated by the construction and properties of the Wasserstein distance. The construction relies on a particular metric on the ... -
