Properties and constructions of codes with the rank and the subspace metric

Ravagnani, Alberto ; Gorla, Elisa (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

In 2000 Ahlswede, Cai, Li, and Yeung discovered that employing coding techniques in network transmissions at the intermediate nodes of the network may give substantial gains in information throughput. These results originated a new research field, called network coding, concerned with efficiency and reliability of communications over networks. Network coding started to draw the attention...

Sporulation capability and metabolic mechanisms of endospore-forming Firmicutes under conditions limiting for growth and survival

Filippidou, Sevasti ; Junier, Pilar (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

Life, as we know it, has physical and chemical limits. More precisely, physical and chemical environmental parameters set the thresholds for reproduction, metabolism and survival for the organisms known to date. Environmental conditions unsuitable for survival and development are the rule rather than the exception in most habitats. Microorganisms have developed various strategies to withstand...

ASQ : active learning with interactive web presentations and classroom analytics

Triglianos, Vasileios ; Pautasso, Cesare (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO013.

Today it is commonly accepted that the effectiveness of instructional technology, measured as improvement over the learning outcomes of students, is highly correlated with the learning environment, the applied pedagogies and the goals of the participants of the learning process. The often applied passive lecture model and the undirected use of modern technology such as student laptops and...

Practical erasure codes for storage systems : the study of entanglement codes, an approach that propagates redundancy to increase reliability and performance

Estrada Galiñanes, Verónica del Carmen ; Felber, Pascal (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

This dissertation deals with the design of practical erasure codes for storage systems. Hardware and logical disk failures are a common source of system failures that may lead to data loss. Nevertheless, it is predicted that spinning disks would remain the standard storage medium in large datacenters. Cloud storage needs efficient codes to become reliable despite its low-cost components. As...

Ramsey spectroscopy in a Rubidium vapor cell and realization of an ultra-stable atomic clock

Gharavipour, Mohammadreza ; Mileti, Gaetano (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Various application fields in industry, telecommunication, navigation and space demand reliable, compact, high-performance frequency standards with a stability level of −14 at 105s (equivalent to <1ns/day). Thanks to semiconductor technology, optical pumping technique with a laser has opened up new schemes based on laser-microwave double-resonance (DR), such as...

The impact of official development assistance on the donor's economy : the case of Switzerland

López, Luciano ; Zarin-Nejadan, Milad (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018 ; 2696.

This thesis investigates the impact of Official Development Assistance (ODA) on the donor's economy in the case of Switzerland. As a first step, chapter 1 discusses a flow-of-funds approach to quantify the impact of bilateral and multilateral ODA on the donor country's economy. The simple yet rigorous methodology employed allows to compute both, the primary (immediate) and the final impacts of...

Energy service contracting : an economic perspective

Klinke, Sandra ; Farsi, Mehdi (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018 ; 2672.

Energy service contracting consists in the outsourcing of energy-related services to a contractor, an Energy Service Company (ESCO), through a long-term contract. This business model has been deemed, in the literature, a promising market-based instrument to foster the deployment of renewable energy and energy conservation projects. This thesis examines empirically the determinants of adoption of...

Time aware location recommendations in location based social networks

Mudda, Steven ; Giordano, Silvia (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO012.

Smartphones have fundamentally changed how people make choices about the products and services they consume and the way they interact with each other. The spread and extensive usage of mobile applications has led to the rise of Location-based Social Network (LBSN) services like Foursquare, Yelp etc, that aim to aim to provide new and novel places of interest to people based on their interests...
