Abstract
Audio bandwidth extension has emerged as a key low bit rate coding tool. In continuation with our on going research on audio bandwidth extension, this paper presents new enhancements to Audio Bandwidth Extension Toolkit (ABET). ABET consists of three primary tools Accurate Spectral Replacement (ASR), Fractal Self Similarity Model (FSSM) and Multi-band Temporal Envelope Amplitude Coding (MBTAC) [1],[2],[3]. Additionally we have also introduced a blind bandwidth extension mode into ABET [4]. We discuss several new ideas / improvements to ABET. Specifically enhancements to the blind bandwidth extension architecture which allow it to work with signals with only 3.5-4.0 kHz audio bandwidth are described. We also elaborate on a new tool for efficient coding of time-frequency envelope which cuts the overhead by 0.75-1.0 kbps/channel. We also address a practical issue i.e., the computational complexity and describe a new low decoder complexity mode of ABET.

Abstract
This paper presents the stability and robustness analysis of an indirect adaptive control based variable structure algorithm for uncertain plants with relative degree one. The indirect approach has been proposed as a way to get an easier design of the switching laws, compared to the direct relationship between the plant transfer function parameters and the physical parameters of the system. Here, a singular perturbation approach is used to establish the robustness of the controller in the presence of unmodelled dynamics and disturbances. It is shown that, for sufficiently small parasitics, the system remains stable with respect to some small residual set.

Abstract
It is well known, widely accepted, scientifically proved and published by major governmental and non-governmental organizations worldwide (e.g. WHO - World Health Organization), that nutritional misbehaviour in so called developed countries, is a major cause of diseases, morbidity and death. The phenomenon is mainly felt in aged populations, but a significant increase has also been detected more recently in young populations. This paper presents a proposal to tackle serious social and behavioural problems related to aging and nutrition. NutriMe is presented as a nutritional monitoring and advising system to help individuals to monitor and correct their behaviours. We also propose NutriMe as the main component for a public national observatory on nutritional profiles for public health analysis purposes.

Abstract
Audience complete action immersion sensation is still the ultimate goal of the multimedia industry. In spite of the significant technical audiovisual advances that enable more realistic contents, coping with individual audience needs and desires is still an incomplete achievement. The proposed project's intention is to contribute for solving this issue through enabling real-time dynamic multimedia storylines with emotional subconscious audience interaction. Individual emotional state assessment is accomplished by direct access to online biometric information. Recent technologic breakthroughs have enabled the usage of minimal invasive biometric hardware devices that no longer interfere with the audience immersion feeling. Other key module of the project is the conceptualization of a dynamic storyline multimedia content system with emotional metadata, responsible for enabling discrete or continuous storyline route options. The unifying component is the definition of the full-duplex communication protocol. The current stage of research has already produced a spin-off product capable of providing computer mouse control through electromyography and has identified key factors in human emotions through experiments conducted in the developed system's architecture that have enabled semi-automatic emotion assessment.

Abstract
A versatile optical imaging system is presented that provides imaging resolutions down to the micrometer range. The system is built for time domain optical coherence tomography, with versatility in the scanning regime to be employed when scanning samples in the transverse and depth directions, thus generating cross-section images (B-scans) by using either transverse priority or depth priority. The system is targeted for eye fundus imaging but is easily adapted for the imaging of other biological samples, in vivo, by using its non-invasive property.
