Automatic computation of continued fraction representations as solutions of explicit differential equations
(2019)
The main focus of this thesis is to present a variation of an algorithm first presented by Maulat and Salvy, with which it is possible to algorithmically guess as well as prove continued fraction expansions of analytical expressions with the help of ordinary differential equations.

Multi-Frequency Microwave Radiometer for Medical Thermography
(2019-09)
Microwave radiometer systems are an entirely non-invasive, non-toxic, avoiding ionizing radiation, and relatively inexpensive detecting modality. The microwave radiometry technique is based on the measurement of natural electromagnetic noise signals emitted by lossy materials. In medicine, microwave radiometry technique offers a non-invasive thermometry method having the potential advantages of monitoring and producing a full map of the temperature deeply inside the human tissues. The method of diagnosing procedures ...

InP - based quantum dots for telecom wavelengths ranges
(2019-12)
Long-distance quantum communication applications require sources of single photons, emitting at telecom wavelengths (around 1550 nm) with minimum attenu-ation losses of silica fiber.
Semiconductor self-assembled InAs/InP-based quantum dots (QDs) are possible candidates to
reach this spectral region. One of the challenges on the way is a QD asymmetry, which limits the fidelity of entangled photons. Therefore, morphological and optical properties of QDs should be improved in order to achieve the necessary quality and ...

‘Libertas’ e monachesimo femminile: l’interazione tra papa e vescovo a livello locale
(Vita e Pensiero, 2019)
Questo contributo si propone di analizzare i rapporti che si instaurarono tra papato e istituzioni monastiche femminili sulla base dei privilegi loro accordati; privilegi che miravano a concedere diritti particolari o libertates, creando così un legame di dipendenza particolare dal papato. A questo scopo è stato scelto il caso del monastero benedettino prima e cistercense dopo di S. Giovanni della Pipia a Cremona. Il momento della fondazione di un’istituzione religiosa e i relativi documenti e privilegi papali ricevuti ...

Discovering Knowledge in Bipartite Graphs with Formal Concept Analysis
(2019)
Since the 1970s knowledge based approaches are a crucial part of artificial intelligence (AI) research. In this work we investigate data sets in the form of bipartite graphs, i.e., graphs where a bipartition of the vertex set respecting the edge set can be found, for knowledge. To this end we first relate those bipartite graphs to the structure formal context, as used in formal concept analysis (FCA). This link enables us to employ the whole tool-set of FCA to bipartite graphs and therefore, notably, to bipartite ...

Implizite Positionierung unter Nutzung des Smartphone-Kompasses
(2019)
Der Ort, an dem ein Nutzer sich in einem Gebäude aufhält, spielt für technische Dienste wie Heimautomatisierung eine zentrale Rolle. In dieser Dissertation wird die Implizite Positionierung vorgestellt, ein neues Verfahren, das den Aufenthaltsort eines Nutzers mittels des Kompasses eines Smartphones erkennt, das der Nutzer bei sich trägt. Das Verfahren findet in den Kompassdaten Muster, die entstehen, wenn Nutzer durch Flure, Treppen, etc. oder um Ecken gehen. Da die Ausrichtungen dieser Orte die Nutzer in ihrer ...

Integration of Heat Pump Storage Systems in Manufacturing Systems via Data Farming and Monte Carlo Simulation
(2019)
The electrification of industrial energy demand is essential for effective climate protection and a successful energy transition. In production systems with fluctuating heating and cooling demands, heat pumps can make a significant contribution to electrification and increased efficiency in a demand-oriented production with automated standby operation. In order to dimension a suitable heat pump storage system, well-founded statistical information about the production system is required. For the creation of stochastic ...

Constraints to commercialisation of smallholder agriculture in Tanintharyi division, Myanmar
(2019-12-17)
Myanmar is a country in rapid economic and political transition, with opportunities emerging for its smallholders to benefit from current economic growth. However many smallholders are trapped in semi-subsistence agriculture, disconnected from markets. Commercialisation can increase farm incomes, and - through the multiplier effect - lead to wider pro-poor growth in the rural economy. However, there are many constraints to commercialisation that prevent this process from occurring. While literature on constraints ...

Responses of Filipino farmers to harsh weather phenomena: A risk perception and attitude study
(2019-12-17)
Small-scale farmers, whose livelihood and food security greatly depends on farming, are constantly exposed and vulnerable to the risks of extreme weather events. The current study explored how the perception and attitude on agricultural risks of small-scale farmers from the upland, lowland and waterside ecosystems in Siniloan, Laguna in Philippines influence the way they respond and cope with extreme weather events. The study employed quantitative and qualitative data collection methods particularly farm surveys, ...
