We consider a dimensionality reducing matrix design based on training data with constraints on its Frobenius norm and number of rows. Our design criteria is aimed at preserving the distances between the data points in the dimensionality reduced space as much as possible relative to their distances in original data space. This approach can be considered as a deterministic Johnson-Lindenstrauss e...

Prior to answering the above questions we need to clarify what is meant by play. Many books have been written on this subject but each author defines play somewhat differently. So do dictionaries. The Oxford Dictionary defines play as 'spontaneous activity of children or young animals', the Chambers English dictionary as 'acts not part of the immediate business of life, but in mimicry or rehear...

The aim of this short series of lectures is to give some impression of what life as a mathematician is like. It has taken me to many parts of the world, and enable me to work with extraordinary people from many different cultures. There will be some mathematical content in the lectures. As Julian Havel said, mathematics is not a spectator sport; I will expect some engagement from you. You may a...

The Distributed Software Engineering (DSE) Group in the Department of Computing, Imperial College consists of 9 academics, 9 research associates and 12 research students. The Department is rated double 5* and the DSE group is world-renowned for its research which combines practical work for building tools for the design and implementation of adaptive distributed systems and networks, with more ...

Future e-Health systems will consist of low-power on-body wireless sensors attached to mobile users that interact with a ubiquitous computing environment. This kind of system needs to be able to configure itself with little or no user input, but more importantly, it is required to adapt autonomously to changes such as user movement, device failure, and the addition or loss of services. We propo...

This paper presents Megame [me-ga-me], a multiplatform game for working memory training and assessment. Megame uses letters and words to amuse, train and assess memory capacity. Based on memory research, the main parameters of the working memory have been identified and some improvement possibilities are presented. While it is not clear that the working memory in itself can be improved, other c...

In \blind signal separation," a collection of linear combinations of signals is broken into its original sources without any knowledge of their initial characteristics. In this paper, we review four important yet fundamentally diierent approaches to this problem. An algorithm by Herault and Jutten emulates structures found in biological systems through a recursive adaptive neural network. In JA...

The article considers a number of genres Arctic films in the world cinema. Among them, some most common are horror (horror), thrillers (part I), dramas, science fiction and action II). socio-political climate times determined evolution influenced their semantic content structure. Their formation production flow has calendar milestone. In second half twentieth century, after end Great Patriotic ...

OBJECTIVES In this pilot study, we intended to assess whether a procedure based on blind source separation (BSS) and subsequent partial reconstruction of magnetoencephalogram (MEG) recordings might enhance the differences between MEGs from Alzheimer's disease (AD) patients and elderly control subjects. MATERIALS AND METHODS We analysed MEG background activity recordings acquired with a 148-ch...
