  2. 6. Broadband and HF radiation from cloud flashes and narrow bipolar pulses

    Author : Noor Azlinda Ahmad; Uppsala universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Remote measurement of electric field generated by lightning has played a major role in understanding the lightning phenomenon. Even though other measurements such as optical, photographic, channel base current and thunder signatures have contributed in this regards, due to practical reasons remote measurements of electric field is considered as the most useful tool in lightning research.

  4. 7. Stimuli Generation Techniques for On-Chip Mixed-Signal Test

    Author : Shakeel Ahmad; Jerzy Dabrowski; Torkel Arnborg; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : With increased complexity of the contemporary very large integrated circuits the need for onchip test addressing not only the digital but also analog and mixed-signal RF blocks has emerged. The standard production test has become more costly and the instrumentation is pushed to its limits by the leading edge integrated circuit technologies. READ MORE

    Keywords : LOH; microsatellite; fragment analysis; DNA sequencing; pyrosequencing; cancer; mutation; variation; SNP; allele-specific extension; apyrase; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Detecting mutations and genomic variations is fundamental indiagnosis, isolating disease genes, association studies,functional genomics and pharmacogenomics. The objective hasbeen to use and further develop a variety of tools andtechnologies to analyze these genetic alterations andvariations. READ MORE

  6. 9. Compliance Control of Robot Manipulator for Safe Physical Human Robot Interaction

    Author : Muhammad Rehan Ahmed; Ivan Kalaykov; Kystof Kozlowksi; Örebro universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical human robot interaction; collision safety; variable stiffness actuators; compliance control; TECHNOLOGY; TEKNIKVETENSKAP; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

    Abstract : Inspiration from biological systems suggests that robots should demonstrate same level of capabilities that are embedded in biological systems in performing safe and successful interaction with the humans. The major challenge in physical human robot interaction tasks in anthropic environment is the safe sharing of robot work space such that robot will not cause harm or injury to the human under any operating condition.
