  1. 1. The mechanics in two nanosized systems Size effect and threshold field

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Martin Olsen; Mittuniversitetet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis investigates the mechanics in two nanosized system. Paper I investigates a size effect in a cantilever nanowire affecting its resonance frequency. Paper II reveals a threshold field for the formation of a mound by the diffusion of surface atoms on a substrate under a STM-tip. READ MORE

  3. 3. The Effects of Lightning on Low Voltage Power Networks

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Raul Montaño; Uppsala universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Lightning induced effects; Lightning Electromagnetic fields; Electromagnetic Compatibility EMC ; Surge Protective Devices SPDs ; Low voltage power networks; Elektroteknik; elektronik och fotonik; TECHNOLOGY Electrical engineering; electronics and photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik;

    Abstract : The present society is highly dependant on complex electronics systems, which have a low damage threshold level. Therefore, there is a high risk of partial or total loss of the system’s electronics when they are exposed to a thunderstorm environment. READ MORE

  4. 4. Ultra-low Voltage Embedded Memories – Design Aspects and a Biomedical Use-case

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Oskar Andersson; Lund University.; Lunds universitet.; [2016-08-15]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRAM; CMOS; ultra-low voltage; ultra-low power; subthreshold; standard-cell based memories; atrial fibrillation; SRAM; CMOS; ultra-low voltage; ultra-low power; subthreshold; standard-cell based memories; atrial fibrillation;

    Abstract : As the Internet of Things (IoT) era emerges the need for ultra-low power (ULP) devices is becoming more eminent. A research-proven approach to achieve ULP consumption is to aggressively lower the supply voltage (VDD) below or in the vicinity of the transistor threshold voltage (Vth) and operate the transistors in the subthreshold (sub-Vth) region.

    Abstract : Silicon nanowires (SiNW) are in the spotlight for a few years in the research community as a good candidate for biosensing applications. This is attributed to their small dimensions in nanometer scale that offers high sensitivity, label-free detection and at the same time utilizing small amount of sample. READ MORE
