Multimedia and real-time applications require bandwidth guarantees, which may be achieved by resource reservation. Several researches were done to propose efficient reservation MAC protocols for ad-hoc networks. In these schemes, channel is segmented into super-frames composed of fixed number of slots. They allocate slots to each traffic source, and make sure that neighbor nodes record the rese...

The performance of listening tests can be a laborious process and requires significant preparation and control to ensure good data quality . This is particularly true for sm all impairment listening tes ts perform ed in accordance to recommendation ITU-R BS.1116-1 [ 1] in dedicated listening rooms under calibrated conditions. The us age of s uch central location testing (CLT) methods is time co...

Performance evaluation of salient features has a long-standing tradition in computer vision. In this paper, we fill the gap of evaluation for the recent wave of binary feature descriptors, which aim to provide robustness while achieving high computational efficiency. We use established metrics to embed our assessment into the body of existing evaluations, allowing us to provide a novel taxonomy...

In this article CCPR, a multidimensional framework for comparative performance evaluation is proposed, which is elaborated and illustrated through a real-life case. A particular feature of the approach is that it takes account of and corrects for the influence of risks, which are beyond the control of the decision maker. Here risk is seen as a multidimensional measure; it is expressed by means ...

This paper studies a text mining problem, comparative sentence mining. A comparative sentence expresses an ordering relation between two sets of entities with respect to some common features. For example, the comparative sentence “Canon’s optics are better than those of Sony and Nikon” expresses the comparative relation: (better, {optics}, {Canon}, {Sony, Nikon}). Given a set of evaluative text...

While natural language generation (NLG) has a strong evaluation tradition, in particular in userbased and task-oriented evaluation, it has never evaluated different approaches and techniques by comparing their performance on the same tasks (shared-task evaluation, STE). NLG is characterised by a lack of consolidation of results, and by isolation from the rest of NLP where STE is now standard. I...

Software engineering society has suggested many methods of software architecture to enhance the preferred quality with concern of performance, reliability, maintainability, usability etc. However little effort is required for systematic comparison of these methods to mind variances and resemblances between existing methods. By using an evaluation framework, we will compare four famous software ...

Currently there are many user-adaptive systems across different application types including education, business and information systems. However, evaluating user-adaptive systems is still a challenging research issue and a difficult task. This is because of the lack of widely accepted evaluation methods, data and the difficulty on generalizing the application areas. In order to provide comparat...

This paper reports a comparative experimental evaluation of proportional derivative and adaptive modelbased control for underwater vehicles. To the best of the authors’ knowledge, this is the first such evaluation of modelbased adaptive tracking control for underwater vehicles during simultaneous dynamic motion in all 6 degrees-of-freedom. This experimental evaluation revealed the presence of u...
