OBJECTIVES The aim of the current study was to analyse the effects of posterior cruciate ligament (PCL) deficiency on forces of the posterolateral corner structure and on tibiofemoral (TF) and patellofemoral (PF) contact force under dynamic-loading conditions. METHODS A subject-specific knee model was validated using a passive flexion experiment, electromyography data, muscle activation, and ...

Manual Handling involves the lifting, carrying, pushing and pulling of materials and objects [1]. Training in safe handling techniques is a recommended way to reduce risk factors associated with manual handling within the working environment, particularly the lifting of low-lying objects as this has long been associated with an increased risk of lower back injuries [2]. However, manual handling...

Oligotrophic tropical coral reefs are built on efficient internal energy and nutrient cycling, facilitated by tight trophic interactions. In the competition for available prey, some small fishes have evolved to feed apparently barren sand patches that connect hard-substratum in many reef habitats. One strategy obtaining prey from a particulate matrix is sift out items sediment (often called ‘wi...

Fast string matching is essential for deep packet inspection (DPI). Traditional string matchers cannot keep up with the continuous increases in data rates due to their natural speed limits. We add a multibyte processing prefilter to the traditional string matcher to detect target patterns on a multiple character basis. The proposed winnowing prefilter significantly reduces the number of identit...

[Purpose] This study compared the electromyographic activity of the quadriceps in hemiplegic patients during the downward, maintenance, and upward phases of squat exercises performed with the feet parallel and with the non-paretic foot lifted. [Subjects] A total of 17 hemiplegic patients (9 males and 8 females) volunteered for this study. [Methods] All subjects performed squat exercises with th...

In recent years a great deal of research efforts in ship hydromechanics have been devoted to practical navigation problems in moving larger ships safely into existing harbors and inland waterways. An area of particular concern is the prediction of ship squat in shallow or restricted waters at different speeds. Squat may cause grounding of the ship which result in severe damage to the ship, and ...
