The effects of two types of auditory distracters (steady-state noise vs. four-talker babble) on visual-only speechreading accuracy were tested against a baseline (silence) in 23 participants with above-average speechreading ability. Their task was to speechread high frequency Swedish words. They were asked to rate their own performance and effort, and report how distracting each type of auditor...

two methods that are used in cognitive psychology both to study cognitive effort and to determine "time processing," i.e., the evolution of cognitive processes while performing a specific task; and to illustrate the use of these methods in design areas which require the use of a computational tool, as it is the case in computer graphics and in web site design. First, relationships between chara...

Non-neutral speech data has a strong negative impact on speech processing systems such as Automatic Speech Recognition (ASR) or speaker ID systems [1]. It is therefore necessary to detect and segment non-neutral speech data before further processing steps. Alternatively, the detection and segmentation of non-neutral speech segments from an input speech stream can be used in speech analysis and ...

A constraint-based framework for computing privacy preserving OLAP aggregations on data cubes is proposed and experimentally assessed in this paper. Our framework introduces a novel privacy OLAP notion, which, following consolidated paradigms of OLAP research, looks at the privacy of aggregate patterns defined on multidimensional ranges rather than the privacy of individual tuples/data-cells, l...

Future Grid Networks should be able to provide Quality of Service (QoS) guarantees to their users. In this work we examine the way Grid resources should be configured so as to provide deterministic delay guarantees to Guaranteed Service (GS) users and fairness to Best Effort (BE) users. The resources are partitioned in groups that serve GS users only, or BE users only, or both types of users wi...

Software effort estimates is an important part of software development work and provides essential input to project feasibility analyses, bidding, budgeting and planning. Analogy-based estimates models emerge as a promising approach, with comparable accuracy to arithmetic methods, and it is potentially easier to understand and apply. Studies show all the models are sensitive to the quality and ...

Amidst the rapid growth of wireless broadband networks, little attention has been paid to wireless network survivability issues. We propose a survivable wireless ATM network architecture that allows it to survive from a single base station failure condition, by redirecting a failure cell’s traffic via its six neighboring cells. We present two failure-handling schemes for the proposed architectu...
