Mobile applications have become ubiquitous, adopted by millions of users that register billions of downloads a day. To increase the competitiveness of the mobile software product, developers should care in a very detailed fashion about the qualities demanded by end users, execution targets and mobile markets. The quality of mobile applications is controlled by market policies, and is judged by customer's reviews and ratings. Software developers need to count on reference points to assess the ...
The main focus of this thesis is the data summary problem, where one takes a large set of multidimensional data points in the Euclidean space, creates a data summary that is much smaller and then uses only the summary to approximately answer range count queries over the data. Range count queries are a crucial tool for data analysis and selectivity estimation in query optimizers. While traditionally the functionality of data summaries is limited to estimates and confidence intervals for the ra...
Software developer's working process could benefit from the support of a recommender system that is able to suggest applicable and useful integrated development environment commands. While previous work focused on prediction methods that can identify what developers will eventually discover autonomously, we built a system that is aimed at recommending commands that are most suitable for the developer's work and are not likely to be discovered without the recommender system. Moreover, we inves...
Nell'esperimento #4, la produzione ottimale di corimbi (35 t ha-1) ਠstata registrata su cavolfiore coltivato in successione al pisello e concimato con 75 kg N ha-1 frazionati in tre applicazioni (25 kg N ha-1 al trapianto, pi๠50 kg N ha-1 distribuiti 35 e 55 giorni dopo il trapianto).
My Ph.D. research is based on an ethnographic investigation of social work advocacy practices toward migrant women who have suffered domestic violence. The investigation was undertaken in a women's shelter located in South Tyrol. The shelter is administered by an association of women and, for the purposes of this thesis, I have named the association DoRi. In previous years, I had practiced as a social worker at this shelter, and had observed the difficulties that frequently obstacle the empow...
The microbial community of the leaf is extremely complex just as the environment that they inhabit. When a perturbation is applied, the microbial community could be affected and change its composition and/or functionality or remained stable. In this context, I studied how the microbial community, fungi and bacteria, of the oak green leaves and leaf litter responds to external disturbance in the area of South Tyrol (Italy). The phyllosphere was subjected to nitrogen aerial fertilization in a s...
Nitrogen (N) is an important nutrient that determines yield in cocoa trees. Atmospheric N (N2) -fixing plants when involved in intercropping systems may provide additional N sources for agricultural crops, thus reducing the need for mineral fertilization. This study has been carried out in five sites in Ghana (during both the dry and rainy season), where cocoa (Theobroma cacao L.) and gliricidia (Gliricidia sepium (Jacq.) Kunth ex Walp.) trees (a N2-fixing species) were either intercropped or...
Estimating biomass and canopy structure is important to characterize forest ecosystems. The characteristics of vegetation at local level affect both ecological and hydrological processes. The increased availability of Airborne Laser Scanning (ALS) surveys and ALS-derived datasets in the last decade pushed forest scientists to find the way to properly exploit the detail information contained to extract forest characteristics. The topic of the present research is the development of a methodolog...
The main object of this work is to prepare nanofibrous membranes (NFM) for the development of novel Enzymatic Membrane Reactors (EMRs) to be used in food processing. EMRs are systems where a biochemical conversion occurs inside a compact and flexible membrane. Such membranes are of special interest in food processing as they can be used for a number of applications in food industries such as: production of electrochemical sensor for the detection of glucose in energy drink and during the be...
Almost 90% of agricultural land in South Tyrol is composed of extensively and intensively used meadows und pastures. Land-use in mountain environments has strong influence on water supply in the lower regions, on soil stability and on hydropower. With the Alpine region not only being influenced by large-scale changes in land-use during the last decades, but also being affected by climate change more than the global mean, it is essential to deeply understand the hydrological mechanisms of Alpi...
