Transformational leadership and organizational commitment : mediating role of leader-member exchange

Keskes, Imen (Date of defense: 01-10-2014)
In the present thesis a theoretical and empirical study of the relationship between transformational leadership (TL) styles and organizational commitment (OC) is performed. These two concepts are examined as multidimensional ...
Singular phenomena in the length spectrum of analytic convex curves

Tamarit Sariol, Anna (Date of defense: 06-07-2015)
Consider the billiard map defined inside an analytic closed strictly convex curve Q. Given q>2 and 02 and 00 is small and continuous so the formulas are exponentially small in 1/h instead. The exponent r has been proved ...
Contributions to QoS and energy efficiency in wi-fi networks

Camps Mur, Daniel (Date of defense: 19-01-2012)
The Wi-Fi technology has been in the recent years fostering the proliferation of attractive mobile computing devices with broadband capabilities. Current Wi-Fi radios though severely impact the battery duration of these ...
The Removal Lemma: algebraic versions and applications

Vena Cros, Lluís (Date of defense: 02-07-2012)
This thesis presents some contributions in additive combinatorics and arithmetic Ramsey theory. More specifically, it deals with the interaction between combinatorics, number theory and additive combinatorics. This area ...
Contributions to the evolution of next generation WLANs

Afaqui, Muhammad Shahwaiz (Date of defense: 28-06-2017)
The explosive growth in usage of IEEE 802.11 based WLAN networks has resulted in dense deployments in diverse environments and has made the concept of anytime - anywhere data connectivity a realm of commercial reality. The ...
Machine learning methods for the analysis of liquid chromatography-mass spectrometry datasets in metabolomics

Fernández Albert, Francesc (Date of defense: 30-10-2014)
Liquid Chromatography-Mass Spectrometry (LC/MS) instruments are widely used in Metabolomics. To analyse their output, it is necessary to use computational tools and algorithms to extract meaningful biological information. ...
The Contribution of Shared Knowledge and Information Technology to Manufacturing Performance: An Evaluation Model

Papoutsakis, Charalampos
The Doctoral Thesis builds and tests a theoretical model that evaluates the contribution of shared knowledge and information technology to manufacturing performance. This is achieved through a sectorial research study among ...
Characterization and modelling of SFRC elements

Blanco, Ana (Date of defense: 20-03-2013)
The use of fibre reinforced concrete (FRC) as a construction material has expanded beyond the traditional applications since the publication of design codes and guidelines. In fact, the industry is demanding FRC with ...
Admission control in mobile cellular networks: design, performance evaluation and analysis

Vesselinova Vassileva, Natalia (Date of defense: 13-04-2012)
Key to the success of the mobile telecommunication systems is provision of mobility and more specifically, continuity of communication sessions on the move. However, from engineering point of view the cobination of scarce ...
Exponentiated weibull fading channel model in free-space optical communications under atmospheric turbulence

Barrios Porras, Ricardo (Date of defense: 17-05-2013)
Free-space optical (FSO) communications is drawing increasing attention as a promising technology to overcome bandwidth shortage, of an evermore crowded wireless marketplace. Currently radio-frequency (RF) technology ...
