    Abstract : Vehicle drivers are a group of workers that are exposed to noise and whole-body vibration (WBV) several hours a day. Some drivers may also be exposed to high mental loads – monitoring and manipulating physical controls while engaging problem solving activities often with strong short-term memory and spatial manipulation components.

  4. 12. Measurements, Analysis Techniques and Experiments in Sound and Vibration : Applied to Operational MRI Scanners and in Remote Laboratories

    Author : Imran Khan; Lars Håkansson; Ingvar Claesson; Josef Ström Bartunek; Gustavo R. Alves; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Noise Control; Remote Laboratories; Sound and Vibration Measurements; Vibration Analysis; Vibration Transmission;

    Abstract : High quality noise and vibration measurements outside of a laboratory environment on real life structures and applications are not trivial. True boundary and operating conditions enforce unique challenges on the measurements. Measurements in hazardous situations such as high magnetic fields, and high temperature environments, etc. READ MORE

  6. 14. Joint Interface Effects on Machining System Vibration

    Author : Qilin Fu; Cornel-Mihai Nicolescu; Tomas Beno; KTH; []
    Keywords : Joint Interface; Vibration; Damping; Chatter; Machining; Carbon NanoComposite; PECVD; HiPIMS; SRA - Production; SRA - Produktion; Järnvägsgruppen - Ljud och vibrationer; Järnvägsgruppen - Ljud och vibrationer;

    Abstract : Vibration problems are still the major constraint in modern machining processes that seek higher material removal rate, shorter process time, longer tool life and better product quality. Depending on the process, the weaker structure element can be the tool/tool holder, workpiece/fixture or both. READ MORE

  7. 15. Health effects from occupational hand-arm vibration

    Author : Per Vihlborg; Pål Graff; Sverre Wikström; Karim Makdoumi; Magnus Svartengren; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hand-arm vibration; Raynaud’s phenomenon; vibration white finger; carpal tunnel syndrome; acute vibration exposure; neuropathy;

    Abstract : Hand-arm vibration (HAV) is a common occupational exposure in Sweden and worldwide that causes both acute transient effects and persistent hand-arm symptoms. The health effects include vibration-induced Raynaud’s phenomenon, neuropathic symptoms, carpal tunnel syndrome (CTS), and musculoskeletal disorders. READ MORE
