Mining code change patterns to aid software development

Fengcai, Wen ; Bavota, Gabriele (Dir.) ; Lanza, Michele (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO012.

Mining Software Repositories (MSR) has become a complete and mature research field, also due to the increasing number of open source projects publicly available. Repository hosting services such as GitHub provide unprecedented access to millions of events generated during development activities (e.g., code commits, pull requests), that can be mined and analyzed to extract new pieces of...

Data mining in Bioprocesses – Knowledge discovery in databases (IIG part)

Artero, Christopher ; Schumann, René (Dir.)

Mémoire de bachelor : Haute Ecole de Gestion & Tourisme, 2021.

The purpose of this thesis is to create clusters from historical data with and without domain knowledge. The method used to cluster the data with domain knowledge is a pattern matching sequence and the method done without domain knowledge is a clustering algorithm that will be defined later. The data had to be retrieved from four old databases, then prepared to be clustered. A...

Text mining for online mental health state and personality assessment

Ríssola, Esteban A. ; Crestani, Fabio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO009.

Advances on psycho-linguistics have evidenced that the ways in which people use words could act as a reliable source to assess a wide array of behaviours. Language use acts as an indicator of the individuals’ current mental state, personality and even personal values. In this thesis, we focus on language analysis to study two closely related processes which encompass integral components of...

Potential for endozoochorous seed dispersal by sheep and goats : Risk of weed seed transport via animal faeces

Oveisi, Mostafa ; Ojaghi, Ahmad ; Rahimian Mashhadi, Hamid ; Müller‐Schärer, Heinz ; Reza Yazdi, Kamran ; Pourmorad Kaleibar, Behnaz ; Soltani, Elias

In: Weed Research, 2021, vol. 61, no. 1, p. 1-12

Endozoochory is known as an important mechanism for the spread of weeds. We carried out experiments to assess the fate of seeds of several weed species (Convolvulus arvensis, Cuscuta campestris, Rumex crispus, Hordeum spontaneum and Sorghum halepense) after passing through the gut of sheep and goat. Eighteen animals of both sheep and goat received diet mixed with seeds of the weed species or ...

Petrophysical joint inversion applied to alpine permafrost field sites to image subsurface ice, water, air, and rock contents

Mollaret, Coline ; Wagner, Florian M. ; Hilbich, Christin ; Scapozza, Cristian ; Hauck, Christian

In: Frontiers in Earth Sc-ience, 2020, vol. 8, p. -

Quantification of ground ice is crucial for understanding permafrost systems and modeling their ongoing degradation. The volumetric ice content is however rarely estimated in permafrost studies, as it is particularly difficult to retrieve. Standard borehole temperature monitoring is unable to provide any ice content estimation, whereas non-invasive geophysical techniques, such as refraction ...

The impact of ambient air pollution on hospital admissions

Filippini, Massimo ; Masiero, Giuliano ; Steinbach, Sandro

In: European Journal of Health Economics, 2019, vol. 20, no. 6, p. 919-931

Ambient air pollution is the environmental factor with the most significant impact on human health. Several epidemiological studies provide evidence for an association between ambient air pollution and human health. However, the recent economic literature has challenged the identification strategy used in these studies. This paper contributes to the ongoing discussion by investigating the...
