1. Rigorous Simulation : Its Theory and Applications
Abstract : Designing Cyber-Physical Systems is hard. Physical testing can be slow, expensive and dangerous. Furthermore computational components make testing all possible behavior unfeasible. Model-based design mitigates these issues by making it possible to iterate over a design much faster. READ MORE

2. Non-conformal gauge/string duality : A rigorous case study
Abstract : The gauge/string duality, a.k.a. the holographic principle is a profound assertion that emerged from string theory. READ MORE

3. Computational dynamics – real and complex
Abstract : The PhD thesis considers four topics in dynamical systems and is based on one paper and three manuscripts.In Paper I we apply methods of interval analysis in order to compute the rigorous enclosure of rotation number. READ MORE

4. Histopathological and immunocytochemical studies in age-associated dementias : the importance of rigorous histopathological criteria for classification of progressive dementia disorders
Abstract : Dementia is an age-associated organic brain disorder, recognizable by the essential features of psychological or behavioral abnormality associated with permanent dysfunction of the brain interfering with social and occupational functioning.There are two clinical and three histopathological forms of dementia 1) primary degenerative dementia, (PDD), or Alzheimer's dementia/Senile dementia of Alzheimers type (AD/SDAT) which is associated with clinical features of uniform progression and insidious onset of symptoms and histopathologically i- dentified by the occurrence of neurofibrillary tangles (NFT) and senile/neuritic plaques (SP/NP) in various cortical and subcor- tical regions; 2) vascular dementia, or multi-infarct dementia (MID), which is associated with clinical features of stepwise progress and patchy distribution of deficits, and histopathologically identified by the occurrence of multiple large and/or small haemorrhagic and/or ischaemic infarcts in various cortical and subcortical regions and 3) intermediate form of dementia or "mixed” ("combined") dementia (AD-MID), which is histopatho- logically associated with the coexistance of symptoms and lesions observed in AD/SDAT and MID, and clinically referred to the MID group.

5. The Lorenz attractor exists
Abstract : We prove that the Lorenz equations support a strange attractor, as conjectured by Edward Lorenz in 1963. We also prove that the attractor is robust, i.e., it persists under small perturbations of the coefficients in the underlying differential equations. READ MORE
