Towards More Sustainable Pavement Management Practices Using Embedded Sensor Technologies

2019

Road agencies are constantly being placed in difficult situations when making road maintenance and rehabilitation decisions as a result of diminishing road budgets and mounting environmental concerns for any chosen strategies. This has led practitioners to seek out new alternative and innovative ways of monitoring road conditions and planning maintenance routines. This paper considers the use of innovative piezo-floating gate (PFG) sensors and conventional strain gauges to continuously monitor the pavement condition and subsequently trigger maintenance activities. These technologies can help develop optimized maintenance strategies as opposed to traditional ad-hoc approaches, which often le…

Fault detection for continuous-time switched systems under asynchronous switching

2013

In this chapter, the problem of FD for continuous-time switched systems under asynchronous switching is investigated. The designed FD filter is assumed to be asynchronous with the original systems. Attention is focused on designing a FD filter such that the estimation error between the residual and the fault is minimized in the sense of H ∞ norm. By employing piecewise Lyapunov function and ADT techniques, a sufficient condition for the existence of such a filter is exploited in terms of certain LMIs. Finally, an example is provided to illustrate the effectiveness of the proposed approach.

Sectors on sectors (SonS): A new hierarchical clustering visualization tool

2011

Clustering techniques have been widely applied to extract information from high-dimensional data structures in the last few years. Graphs are especially relevant for clustering, but many graphs associated with hierarchical clustering do not give any information about the values of the centroids' attributes and the relationships among them. In this paper, we propose a new visualization approach for hierarchical cluster analysis in which the above-mentioned information is available. The method is based on pie charts. The pie charts are divided into several pie segments or sectors corresponding to each cluster. The radius of each pie segment is proportional to the number of patterns included i…

Understanding the role of entrepreneurial behavior in SMEs

2015

From my real life experience and as a student studying in the University of Jyväskylä, I have developed an interest on the importance of becoming either a philanthropist or industrialist. This actually led to my inquiry into the world of a social and business enterprise in relationship to how they impact the society. The study of Entrepreneurship therefore has broaden my ideology on business and this has led to knowing about the conflicting views of its definition and what makes a successful entrepreneur? The following research work will examine how Entrepreneurial behavior interpretes to the growth of a business enterprise and what are the behavior(s) that encourages exploration and exploi…

L'utilisation du médiateur ludique pour favoriser le développement des compétences non-académiques en formation supérieure

2015

The competency-based curriculum is being more and more used in France, and leads to pedagogical changes. This raises questions about what to teach, and how to teach. More specifically, the characteristics of thegeneration Y, including the fact that this generation considers education as a consumption value, being engaged only if they get some direct personal benefits, leads to invest some methods of innovative pedagogy, in order to get students’ interest and engagement. At the same time, literature about soft skills, show the importance of those skills for success, encouraging to more include soft skills in education. The research presented in this thesis, aims to assess how a games-based a…

Ion traps in nuclear physics : recent results and achievements

2016

Ion traps offer a way to determine nuclear binding energies through atomic mass measurements with a high accuracy and they are routinely used to provide isotopically or even isomerically pure beams of short-living ions for post-trap decay spectroscopy experiments. In this review, different ion-trapping techniques and progresses in recent nuclear physics experiments employing low-energy ion traps are discussed. The main focus in this review is on the benefit of recent high accuracy mass measurements to solve some key problems in physics related to nuclear structure, nuclear astrophysics as well as neutrinos. Also, several cases of decay spectroscopy experiments utilizing trap-purified ion sa…
