  1. 6. Numerical methods for inverse heat conduction problems

    University dissertation from Linköping : Linköpings universitet

    Author : Fredrik Berntsson; Linköpings universitet.; Linköpings universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ill-posed; Heat Conduction; Regularization; MATHEMATICS; MATEMATIK;

    Abstract : In many industrial applications one wishes to determine the temperature history on the surface of a body, where the surface itself is inaccessible for measurements. The sideways heat equation is a model of this situation. READ MORE

  2. 7. Ionic Conduction and Bond Valence in Glasses

    University dissertation from Linköping : Linköpings universitet

    Author : Andreas Hall; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutron; Phosphate; Borate; reverse Monte Carlo; Glass; Bond Valence; Structure; Diffraction; X-ray; Ion Conduction;

    Abstract : Ion conducting glasses are highly interesting for several different applications, among them, chemical sensors, smart windows with variable optical properties and as electrolytes in batteries. The last example can take full advantage of the ease with which a thin film (... READ MORE

  3. 8. A Novel Bone Conduction Implant System

    University dissertation from Linköping : Linköpings universitet

    Author : Hamidreza Taghavi; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sound radiation; amplitude modulation; low-power systems.; bone conduction implant; feedback; bone anchored hearing aid; RF power amplifier; gain headroom; implantable transducer; wireless power and data transmission; RF power and data link;

    Abstract : Bone conduction is the process by which an acoustic signal vibrates the skull bones to stimulate the cochlea. Patients with pure conductive hearing loss, mixed hearing loss, and single sided deafness are sometimes poorly rehabilitated by conventional air conduction hearing aids due to for example the functionality losses in the middle ear.

  4. 9. On Direct Drive Bone Conduction Devices - Hearing Rehabilitation and Objective Assessment of Stimulation Methods

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Cristina Rigato; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone Conduction Implant; vibrations; audiology; comparative study; Bone Conduction Devices; active transcutaneous; Direct Drive;

    Abstract : Bone conduction devices (BCDs) rely on the transmission of sound in form of vibrations generated by a transducer to the inner ear via the skull and surrounding soft tissues. Direct drive BCDs stimulate the skull bone directly, either via a skin-penetrating abutment (BAHAs, Bone Anchored Hearing Aids), or with a transducer implanted under intact skin (active transcutaneous devices).

  5. 10. The Role of Impaired Interatrial Conduction in Paroxysmal Atrial Fibrillation

    University dissertation from Lund University

    Author : Pyotr Platonov; Lunds universitet.; Lund University.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electrophysiology; Cardiovascular system; anatomy; interatrial conduction; lone atrial fibrillation; Kardiovaskulära systemet;

    Abstract : Popular Abstract in Swedish Projektet har for avsikt att vardera den elektriska overledningen mellan hjartats formak och hur forsamring av denna overledning bidrar till uppkomsten av attackvis pakommande formaks- flimmer. Studierna har anvant sig av ekg- registreringar fran kroppsytan, registreringar fran hjartats insida, anatomiska dissektionsstudier och djurexperiment. READ MORE
