    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; condensed matter; electrics; electrical; materials science; Elektroteknik; elektronik och fotonik; TECHNOLOGY Electrical engineering; electronics and photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik;

    Abstract : The continuing shrinkage of semiconductor devices towards nanoscale features and increased functionality has prompted a strong need for high-resolution characterization tools capable of mapping the electrical properties with nanoscale lateral resolution. In this regard, scanning capacitance microscopy (SCM) scanning spreading resistance microscopy (SSRM) and Kelvin probe force microscopy (KPFM) have emerged as powerful techniques. READ MORE

  4. 2. Physics of Electrical Discharge Transitions in Air

    University dissertation from KTH Royal Institute of Technology

    Abstract : Electrical bioimpedance spectroscopy (EBIS) has been used to assess the status or composition of various types of tissue, and examples of EBIS include body composition analysis (BCA) and tissue characterisation for skin cancer detection. EBIS is a non-invasive method that has the potential to provide a large amount of information for diagnosis or monitoring purposes, such as the monitoring of pulmonary oedema, i. READ MORE

  6. 4. Electrical Bioimpedance Cerebral Monitoring: Fundamental Steps towards Clinical Application

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Fernando Seoane Martinez; [2007]

    Abstract : Neurologically related injuries cause a similar number of deaths as cancer, and brain damage is the second commonest cause of death in the world and probably the leading cause of permanent disability. The devastating effects of most cases of brain damage could be avoided if it were detected and medical treatment initiated in time. READ MORE

  7. 5. Distributed Topology Inference for Power System Applications Algorithms and architectures utilising industry standards

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Abstract : The electrical transmission and distribution system is undergoing unprecedented changes to meet the need for a carbon emission-free global energy system. An expected increase in the portion of end-user energy use in the form of electricity and need to integrate renewable energy sources into the power grid on a large scale require major changes in how power grids are operated and controlled.
