Design space exploration in high-level synthesis

Ferretti, Lorenzo ; Pozzi, Laura (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO016.

High Level Synthesis (HLS) is a process which, starting from a high-level description of an application (C/C++), generates the corresponding RTL code describing the hardware implementation of the desired functionality. The HLS process is usually controlled by user-given directives (e.g., directives to set whether or not to unroll a loop) which influence the resulting implementation area and...

Neuroticism in the digital age : a meta-analysis

Marciano, Laura ; Camerini, Anne-Linda ; Schulz, Peter J.

In: Computers in human behavior reports, 2020, vol. 2, no. August–December, p. 14 p

The pervasiveness of the Internet has raised concern about its (problematic) use and the potentially negative impact on people's health. Neuroticism has been identified as one potential risk factor of Internet and other online addictions. To obtain a comprehensive quantitative synthesis of the association of neuroticism and both overall and problematic Internet activities, a meta-analysis was...

The signed distance measure in fuzzy statistical analysis : Some theoretical, empirical and programming advances

Berkachy, Rédina ; Donzé, Laurent (Dir.)

Thèse de doctorat : Université de Fribourg, 2020.

This thesis intends to present some advances in fuzzy statistical analyses. A particular distance between fuzzy numbers called the signed distance, seems to be appealing because of its directional property. It has the ability of describing the direction of travel between two fuzzy numbers. In addition, it has been often used as a fuzzy ranking tool or a defuzzification operator. Despite the...

Novel insights on the geomagnetic field in West Africa from a new intensity reference curve (0-2000 AD)

Kapper, Lisa ; Serneels, Vincent ; Panovska, Sanja ; Ruíz, Rafael García ; Hellio, Gabrielle ; Groot, Lennart de ; Goguitchaichvili, Avto ; Morales, Juan ; Ruíz, Rubén Cejudo

In: Scientific Reports, 2020, vol. 10, no. 1, p. 1121

The geomagnetic field variations on the continent of Africa are still largely undeciphered for the past two millennia. In spite of archaeological artefacts being reliable recorders of the ancient geomagnetic field strength, only few data have been reported for this continent so far. Here we use the Thellier-Coe and calibrated pseudo- Thellier methods to recover archaeointensity data from...

Asset prices and demand shocks

Barbon, Andrea ; Franzoni, Francesco (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO002.

My dissertation consists of three chapters, each of which focuses on a different area of research in asset pricing. The first chapter deals with the informational role of brokerage firms during fire sales in the equity market. The second chapter exploits the ETF program by the bank of Japan as a quasi-natural experiment to measure the slope of the equity demand curve. The last chapter presents...

Competing Institutional Logics and Paradoxical Universalism : School-to-Work Transitions of Disabled Youth in Switzerland and the United States

Tschanz, Christoph ; Powell, Justin J. W.

In: Social inclusion, 2020, vol. 8, no. 1, p. 155-167

Disablement is a complex social phenomenon in contemporary societies, reflected in disability policies oriented towards contrasting paradigms. Fraught with ambivalence, disability raises dilemmas of classification and targeted supports. Paradoxical universalism emphasizes that to achieve universality requires recognizing individual dis/abilities and particular contextual conditions and barriers...

Kompetenzbereich "Forschungsmethoden" : was sollen angehende Lehrpersonen am Ende ihrer Ausbildung aus der Sicht von in der Forschungsausbildung tätigen Dozierenden können? = Competence area «research methods» : what skills do lecturers in research methodology expect pre-service teachers to have acquired by the end of their training?

Vetter, Peter ; Gerteis, Markus ; Moroni, Sandra

In: Beiträge zur Lehrerinnen- und Lehrerbildung, 2019, vol. 37, no. 2, p. 160-176

The article examines the question as to what skills pre-service teachers should have acquired by the end of their training in research methodology. To that end, we fi rst set a conceptual framework. Based on a quantitative survey of lecturers who provide training in research (N = 28), we then present the expectations that pre-service teachers are supposed to fulfi ll. The results show that the...

The digital birth of an African city : the case of Douala

Pucciarelli, Marta ; Cantoni, Lorenzo (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019COM003.

This dissertation focuses on the online communication and representation of a digital city in Africa: Douala, the largest city of the Republic of Cameroon. In particular, it explores the evolution of the web-based reproduction (Couclelis, 2004) of Douala, the largest city of the Republic of Cameroon, from a chronological, spatial and representational perspective, with the purpose of...

Conditioning groundwater flow parameters with iterative ensemble smoothers : analysis and approaches in the continuous and the discrete cases

Lam, Dan-Thuy ; Renard, Philippe (Dir.) ; Kerrou, Jaouher (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Data assimilation (DA) consists in combining observations and predictions of a numerical model to produce an optimal estimate of the evolving state of a system. Over the last decade, DA methods based on the Ensemble Kalman Filter (EnKF) have been particularly explored in various geoscience fields for inverse modelling. Although this type of ensemble methods can handle high-dimensional systems,...
