Coarse Grained Reconfigurable Arrays have emerged, in recent years, as promising candidates to realize efficient reconfigurable platforms. CGRAs feature high computational density, flexible routing interconnect and rapid reconfiguration, characteristics that make them well-suited to speed up execution of computational kernels. A number of designs embodying the CGRA concept have been proposed...

My dissertation aims at understanding the impact of uncertainty and disagreement on asset prices. It contains three main chapters. Chapter One gives a general introduction into the topic of partial information and heterogeneous beliefs. Chapter Two explains the link between credit spreads and the heterogeneous formation of expectations in an economy where agents with different perception of...

This dissertation develops and tests theories on identity-based resource partitioning in the context of the German electricity market after deregulation in 1998. I apply insights from the recent theoretical development on organizational identity and pay special attention to the roles of audience heterogeneity which is observed through the lens of geography. Based on both theoretical arguments...

The goal of this PhD Thesis is the definition of new robust estimators, thereby extending the available theory and exploring new directions for applications in finance. The Thesis contains three papers, which analyze three different types of estimators: M-, Minimum Distance- and R- estimators. The focus is manly of their infinitesimal robustness, but global robustness properties are also...

The present dissertation has as a main goal to identify and describe relevant design and communication processes taking place during co-design meetings, in a way suitable to inform practice in similar settings in the field of eLearning design and development. The need for such a research emerges from the inadequacy of prescriptive models that can guide professionals in their communication...

Following the industrial demand to address the problem of software correctness, the computer science research community puts a lot of efforts into development of scalable and precise formal methods that are applicable to industrial-size programs. Unfortunately, most of software verification techniques suffer from the effect of combinatorial blowup also known as a "state-space explosion", i.e.,...

This doctoral thesis focuses on fixed income markets exploring two essential questions in this area: (i) the risk compensation for holding Treasury bonds and (ii) the behavior of interest rate volatilities across different maturities. The objective is to understand the effect of changes in risk premia and in yield volatilities on bond prices, identify their economic drivers, and to propose...

This thesis is made of three articles dealing with two main subjects: the so called "Kernel Puzzle" and the problem of immunization of portfolio of treasury and corporate bonds. For the first topic, we provide a new method to derive the state price density per unit probability based on option prices and GARCH model. We derive the risk neutral distribution using the result in Breeden and...

This dissertation examines individual opinion formation in the context of the smoking ban that was voted in Ticino in March 2006 using a complex model that includes selfinterest, political predispositions, media use, interpersonal discussion and perception of community support for the policy proposal. These variables were assumed to impact individual's belief systems (salience of the different...

This dissertation analyzes argumentative interactions in the context of corporate takeover bids, representing thus a first systematic study of financial communication from the perspective of argumentation theory. In general, the importance of financial communication is justified by the relevance of information for making sound investment decisions (cf. Healy Williams 2008)....
