Special Education in Greek Multicultural and Inclusive School Classrooms: A Primary Research in Secondary Education Schools of Ioannina
Social inclusion, worldwide, has become the focus of governments for their policies. Education is seen as a key driver for achieving social inclusion and cohesion. The separation between mainstream and special school hampers the idea of including different students in education (Lareau & Horvat, …

Exploring the Use of Wearables to Enable Indoor Navigation for Blind Users
One of the challenges that people with visual impairments (VI) have to have to confront daily, is navigating independently through foreign or unfamiliar spaces.Navigating through unfamiliar spaces without assistance is very time consuming and leads to lower mobility. Especially in the case of …

From spatio-temporal data to a weighted and lagged network between functional domains: Applications in climate and neuroscience
Spatio-temporal data have become increasingly prevalent and important for both science and enterprises. Such data are typically embedded in a grid with a resolution larger than the true dimensionality of the underlying system. One major task is to identify the distinct semi-autonomous functional …

Approximation of Multiobjective Optimization Problems
We study optimization problems with multiple objectives. Such problems are pervasive across many diverse disciplines -- in economics, engineering, healthcare, biology, to name but a few -- and heuristic approaches to solve them have already been deployed in several areas, in both academia and …

Fight and flight: Behavioural drivers and evolutionary consequences of resource competition in birds
Animal competition determines the allocation of resources required for individual survival and reproductive success. These consequences of competition drive selection for traits that confer competitive advantages. While previous studies have quantified effects of fundamental behaviours on …

A Stochastic Lagrangian Model for Non-Gaussian Fluid Turbulence and Its Application to Describe Particle Dispersion in a Channel
Stochastic Lagrangian simulations are computationally efficient, since the equations to be solved are not partial differential equations as in the direct simulations. They are ideally suited for parallel computers. The stochastic model is about 120 times faster than the DNS on a single processor on …

Many-body effects in metals, modulation doped quantum wells and doped semiconductors
A new approach to the problem of X-ray edge singularities and peaks of many-body origin observed in the optical spectra is presented. We first establish the analogy between a system of one hole interacting with many electrons and the polaron, where one electron interacts with many phonons. We …

Network and storage stack specialisation for performance
In order to serve hundreds of millions of users, contemporary content providers employ tens of thousands of servers to scale their systems. The system software in these environments, however, is struggling to keep up with the increase in demand: contemporary network and storage stacks, as well as …

Collective intelligence at Enron during the California energy crisis : uncovering collaborative innovation networks using social network analysis
As interaction takes place between individuals, relationships are formed and collaboration and innovation emerge. In this thesis I have applied Coolfarming (Gloor, 201 lb), a social network analysis method using Condor, a software tool to quantify communication patterns based on various data …

Computational and statistical challenges in high dimensional statistical models
This thesis focuses on two long-studied high-dimensional statistical models, namely (1) the high-dimensional linear regression (HDLR) model, where the goal is to recover a hidden vector of coefficients from noisy linear observations, and (2) the planted clique (PC) model, where the goal is to …

Development of innovative approaches for life extension of railway track systems
… relevant to the industry by the two sponsors, Dr Ilias Oraifige, Senior Academic and Reader at the University of Derby and Ken Mee, Managing Director of Quality and Safety Services Ltd. The term “life extension” was uniquely created and applied to railway infrastructure by the author and his teams …

Darstellung und Bewertung funktioneller Ergebnisse nach Beugesehnenersatzplastiken der Hand
In der Zeit von Mai 1992 bis Februar 1998 wurden in der Handchirurgie der Universitätsklinik Würzburg insgesamt 25 Patienten an 27 Fingern mit einer zweizeitigen Beugesehnenersatzplastik operiert. Die Ergebnisse sind sehr unterschiedlich. Patienten mit glatten Schnittverletzungen und einem Alter …

Measurement and Analysis of Rider Input and Motorcycle Response in High-Performance Environments
This thesis presents the development and validation of a novel rider input measurement platform designed to capture and analyse key rider inputs, including handlebar forces, footpeg inputs, and steering torque, to better understand rider and motorcycle behaviour in high-performance settings. The …

Structural determinants of mutability across cancer genomes
Cancer is a group of diseases which are characterised and actuated by somatic mutations. In cancer the distribution of mutations across the genome is inhomogeneous, with genomic and epigenomic features influencing mutational patterns. Previous studies have indicated that chromatin organization and …

The Third Energy Package gas Directive (2009/73/EC): compliance in Lithuania and Romania
"Threats posed to EU's energy security during the last fifteen years, made the Commission to develop the Energy Policy promoting the integration and the creation of the Internal Energy Market. The ""Third Energy Package"" was introduced in 2009 aiming to promote the liberalization of the market but …
