  1. 11. Motion Analysis and Postural Stability of Transtibial Prosthesis Users

    Författare :David Rusaw; Göteborgs universitet; []
    Nyckelord :Artificial limb; balance; electromyography EMG ; motion analysis; postural stability;

    Sammanfattning : The AIMS of the thesis were to critically evaluate motion analysis methods used during investigations of transtibial prosthesis users, and to propose improvements to these methods. Additionally, the aim was to evaluate if vibratory feedback could be used to improve postural stability in transtibial prosthesis users and how being a prosthesis user influenced muscular response to postural perturbations.

  3. 12. Accelerating Distributed Storage in Heterogeneous Settings

    Författare :Waleed Reda; Dejan Kostic; Peter Van Roy; Marco Chiesa; Adam Morrison; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed storage; File systems; Hardware offload; Persistent memory; Distribuerad lagring; Dilsystem; Maskinvaruavlastning; Beständigt minne; Computer Science; Datalogi;

    Sammanfattning : Heterogeneity in cloud environments is a fact of life—from workload skews and network path changes, to the diversity of server hardware components, these are all factors that impact the performance of distributed storage. In this dissertation, we identify that heterogeneity can in fact be one of the primary causes of service degradation for storage systems. LÄS MER

  4. 13. The face of wrath : how facial emotion captures visual attention

    Författare :Daniel Lundqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Faces; Facial expressions; Schematic faces; Threatening faces; Emotion; Semantic differential scales; Activity; Potency; Negative Evaluation; Attention; Visual search;

    Sammanfattning : We look at the things that matter to us. We may rest our eyes on things that attract us, stare at something horrifying, or glare at someone we dislike: things that affect us emotionally are also things that capture our visual attention. LÄS MER

  5. 14. A Purkinje cell Timing Mechanism. On the Physical Basis of a Temporal Duration Memory

    Författare :Fredrik Johansson; Associativ inlärning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cerebellum; Purkinje cell; Timing; Temporal; Memory; Eyeblink conditioning; mGluR7; Kir3; GIRK;

    Sammanfattning : The standard view of neural signaling is that a neuron can influence its target cell by exciting or inhibiting it. Learning is thought to involve strengthening or weakening synaptic connections. For most behaviors, the brain must learn to produce precisely timed activity patterns. LÄS MER

  7. 15. Clinical Electrocochleography in Menière´s disease

    Författare :Kornel Sass; Lund Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intrathoracic pressure; perilymphatic fistula; pressure exposure; endolymphatic hydrops; Menière´s disease; reproducibility; specificity; sensitivity; rarefaction click; condensation click; electrocochleography; summating potential; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Sammanfattning : Electrocochleography (ECoG) is an objective method to evaluate cochlear electrophysiology. The recordings are considered to reflect the mechano-electric processes of the cochlea, and can indicate the presence of suspected endolymphatic hydrops. LÄS MER
