BABA in priming tomato for enhanced tolerance to drought, salinity and fungal stress and combinations thereof

Ben Rejeb, Ines ; Mauch-Mani, Brigitte (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Tomatoes are among the most produced and consumed vegetable-fruit in many countries and is considered an economically important crop. However, drought, salinity and pathogen infection are the main causes of crop yield reduction and variability. Although plants have developed defensive capacities against these stresses, but plant tolerance and resistance depend on the degree and intensity of...

Courtship communication in the wild chimpanzees of Budongo, Uganda

Fallon, Brittany Laurie Ann ; Zuberbühler, Klaus (Dir.) ; Byrne, Richard (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

This thesis examines wild chimpanzee mating behaviour, and considers in particular the role of communication during mating. Previous studies have focused on compiling behavioural ethograms, or on a small subset of courtship signals. More generally, research on chimpanzee sexual behaviour has rarely looked at intentional communication, but instead focused on a handful of courtship tactics, such as...

Social dimensions of public large-scale wi-fi networks : the cases of a municipal and a community wireless network

Picco-Schwendener, Anna ; Cantoni, Lorenzo (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018COM011.

Wireless networks play an increasingly important role in today’s mobile and interconnected society. People use mobile devices such as smartphones, tablets or portable game consoles on a regular basis to interact, retrieve and share information, and to orient and entertain themselves. However, in order to be fully performant these devices need to be connected to the Internet. Thanks to very...

Derivative securities in risk management and asset pricing

Legnazzi, Chiara ; Barone-Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO009.

The high informational content and the ease of accessibility are among the most attractive features which make derivative securities particularly useful in financial applications. With a special focus on risk management and asset pricing, I present several methodologies which involve the use of option and futures data in the estimation process. This doctoral thesis consists of three chapters....

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...
