The influence of different seat properties on the head-neck motion during a low-velocity rear-end impact was tested using a Hybrid III-dummy fitted with a modified neck (RID-neck). The results show that by modifying the properties of the seat-back and head-restraint it is possible to influence the head-neck kinematics to a great extent. It was possible to virtually eliminate the neck extension ...

This paper describes a real-time vision-based system that detects vehicles approaching from the rear in order to anticipate possible rear-end collisions. A camera mounted on the rear of the vehicle provides images which are analysed by means of computer vision techniques. The detection of candidates is carried out using the top-hat transform in combination with intensity and edge-based symmetri...

BACKGROUND There are many ways to treat aseptic non-union of femoral shaft fractures with reported varied success rate. Amongst all these, Exchange nailing is the simplest and most successful technique for treating aseptic non union of femoral shaft fractures. We have carried out a prospective study in the Department of Trauma & Orthopaedics, Ayub Medical College Abbottabad to analyse the role ...

The adult peripheral nervous system of Drosophila includes a complex array of mechanosensory organs (bristles) that cover much of the body surface of the fly. The four cells (shaft, socket, sheath, and neuron) which compose each of these organs adopt distinct fates as a result of cell-cell signaling via the Notch (N) pathway. However, the specific mechanisms by which these cells execute their c...

BACKGROUND To study phacoemulsification probe shaft/wound and corneal surface/tip temperatures in vivo during longitudinal, torsional and combined phacoemulsification modes and their relationship to machine parameters. DESIGN This was a prospective study at Chaithanya Eye Hospital and Research Institute, Trivandrum, India (tertiary). PARTICIPANTS Twenty-two eyes of 22 patients were randomiz...

The paper presents a new approach to the parameter identification of a wind turbine shaft vibrations measured with piezoelectric sensor. The system order and unknown processes matrices are determined using the wind force as the model input and wind turbine shaft vibrations as the model output. The identified model can be used to estimate the shaft vibrations and design an early damage monitorin...

We report the results of a three-year study of bifocal fractures of the tibia and fibula, excluding segmental shaft fractures. In our whole series, these formed 4.7% of all tibial diaphyseal fractures. We describe three groups: bifocal fractures of both the proximal and the distal joint surfaces, fractures of the shaft and tibial plateau, and fractures of the shaft and ankle. These groups of fr...

Introduction This paper summarizes my collection of research findings on the role of shaft flexibility in the golf swing. The research was initiated during my PhD thesis under the supervision of Dr. Eric Sprigings. The goal was to gain a comprehensive understanding of the role that shaft stiffness plays in the golf swing. This paper will provide a rationale for the methodologies I’ve used, a su...
