In this paper, we address the problem of estimating image features whenever they become unavailable during a vision-based task. The method consists in using numerical algorithm to compute the lacking data and allows to treat both partial and total visual features loss. Simulation and experimental results validate our work for two different visual-servoing navigation tasks. A comparative analysi...

One of the major overheads that prohibits the wide spread deployment of parallel discrete event simulation (PDES) is the need to synchronize the distributed processes in the simulation. Considerable investigations have been conducted to analyze and optimize the two widely used synchronization strategies, namely the conservative and the optimistic simulation paradigms. However, little attention ...

This paper presents a region-representation scheme and comparative analysis methods based on a tesseral addressing system. The proposed scheme is described in the context of performance analysis of Page Segmentation methods, a Document Image Analysis area that is particularly sensitive to both a successful region-description scheme and efficient methods for comparative analysis. The proposed te...

I agree with much of what Michael Shalev (2007) says in his paper, both about the limits of multiple regression and about how to improve quantitative analysis in macro-comparative research. With respect to the latter, Shalev suggests three avenues for advance: (1) improve regression through technical refinement; (2) combine regression with case studies (triangulation); (3) turn to alternative m...

Abstract. This paper deals with the clustering task for Russian texts obtained using automatic speech recognition (ASR). The input for processing are recognition result for phone call recordings and manual text transcripts for these calls. We present a comparative analysis of clustering results for recognition texts and manual text transcripts, make an evaluation of how recognition quality affe...

This paper seeks with the comparative analysis of MAC protocols in wireless cellular networks. Theory begins with a short overview of basic cellular networks. Then special MAC algorithms for world of wireless are discussed according to the particular type of wireless networks like wireless cellular networks. A description of these algorithms and protocols together with their issues and comparis...

The present Article is an attempt to analyze the scheme of Separation of Powers as envisaged under the Indian Constitution and the difficulties faced by the three wings of the government in practice while implementing the provisions of the Constitution in letter and spirit. The author also draws a comparative analysis with the American Constitution scheme of Separation of Powers. Throughout the...

This paper deals with a comparative analysis of two different packaging and transport scenarios, which exemplifies the implications of choosing between single-use and reusable packaging. In particular, transport of a batch of chemicals by means of disposable fibre drums vs. reusable steel drums is investigated from a life cycle perspective, and the associated environmental impact in terms of Gl...
