1. Differential Protection for Arbitrary Three-Phase Power Transformers
Abstract : This thesis describes how to provide standardized, current based, differential protection for any three-phase power transformer, including phase-shifting transformers with variable phase angle shift and transformers of all construction types and internal on-load tap-changer configurations. The use of standard transformer differential protection for such applications is considered impossible in the protective relaying standards and practices currently applied. READ MORE

2. Multi-terminal HVDC protections based on transient line modeling
Abstract : High voltage direct current (HVDC) is considered one of the critical technologies required for the power system to enable the transition toward renewables. With an increasing geographical density of HVDC converters, there is a potential for optimization by connecting more than two converters into a shared DC transmission system, thus forming a multi-terminal HVDC (MTDC) system.

4. Go the Extra Mile for Accountability : Privacy Protection Measures for Emerging Information Management Systems
Abstract : The thesis considers a systematic approach to design and develop techniques for preventing personal data exposure in next generation information management systems with the aim of ensuring accountability of data controllers (entities that process personal data).With a rapid growth in the communication technologies, heterogenous computing environments that offer cost-effective data processing alternatives are emerging.

5. Asymptomatic Bacteriuria. Protection against, and differential diagnosis towards symptomatic Urinary Tract Infection
Abstract : Urinary tract infections (UTIs) are among the most common infectious diseases in humans, with a subset of sus- ceptible individuals who experience recurrent episodes. e increase in antibiotic resistance in gram-negative uropathogens, due to antibiotic overuse, is a strong rationale for developing therapeutic alternatives and to improve diagnostics.
