Na0.5Bi0.5TiO3-based materials with mechanical-stress-dependent dielectric properties

Author(s): Jakob König (Author), Danilo Suvorov (Supervisor), Boštjan Jančar (Co-Supervisor)

Year: 2009

Type: Doctoral dissertation

The stress dependence of the electrical permittivity offers a convenient way of measuring pressure. This effect is suitable for static and quasi-static stress applications, where the conventional method based on the piezoelectric effect becomes inadequate. Although the principle of applying this effect for pressure sensing has been known for almost …

Monitoring of the product quality in manufacturing industries

Author(s): Jani Kleindienst (Author), Đani Juričić (Supervisor)

Year: 2009

Type: Doctoral dissertation

Unexpected production breakdowns and unpredictable defects in product quality remain critical problems in modern manufacturing systems. Usually occuring by no obvious exterior cause and often during periods of smooth production, they lead to production losses and reduced process availability, which results in lower profit rates. Conventional statistical methods of process …

Development of an alternative approach to membrane protein structure determination based on the analysis of local rotational conformational spaces

Author(s): Aleh Kavalenka (Author), Janez Štrancar (Supervisor)

Year: 2009

Type: Doctoral dissertation

The problem of structure determination of membrane proteins is addressed with a new combination of site-directed spin labelling (SDSL) electron paramagnetic resonance (EPR) spectroscopy and structure modelling of a protein and its conformational spaces. This new approach is aimed at structural characterization of membrane proteins and intrinsically disordered proteins. In …

Network Models of Self-Assembled Functional Materials

Author(s): Milovan Šuvakov (Author), Bosiljka Tadić (Supervisor)

Year: 2009

Type: Doctoral dissertation

The fabrication of functional materials composed of metallic nanoparticles is one of the most important steps in the contemporary nanotechnology. Nonlinear selfassembly of nanoparticles into macroscopic aggregates are promising methods in which various structures can be obtained by tuning certain control parameters. Such large-scale aggregates exhibit new physical features, which …

Modular gene dynamics and network theory at mesoscopic scale

Author(s): Zoran Levnajić (Author), Bosiljka Tadić (Supervisor), Tomaž Prosen (Co-Supervisor)

Year: 2009

Type: Doctoral dissertation

Complex dynamical systems are often modeled as networks, with nodes representing dynamical units which interact through the network’s links. Gene regulatory networks, responsible for the production of proteins inside a cell, are an example of system that can be described as a network of interacting genes. The behavior of a …
