Since many years Doppler radar profilers are known as valuable tools to retrieve profiles of rain rate and further rain parameters (e.g. Wakasugi et al. (1986)). Applying well established relations for terminal fall velocity, shape and backscatter cross section of rain drops allows to derive rain rate without empirical assumptions. For calculating the backscatter cross section, the flattening o...

The signal induced by an electron on a pickup strip has been calculated in a RPC used in INO calorimeter [1] following Ramo’s theorem [2]. An accurate estimation of weighting field has been obtained using a nearly exact Boundary Element Method (neBEM) solver [3] while the electron velocity from the real field values. The calculation has shown a growth and subsequent fall of pickup signal with d...

Retropharyngeal haematoma as a cause of acute airway obstruction is uncommon and following low velocity neck hypertension is rare. We report the case of a 76-year-old man who, following a fall with neck hyperextension, developed a retropharyngeal haematoma which caused airway obstruction requiring cricothyroidotomy. Initially he complained of no neck pain. We discuss the importance of airway an...

The majority of mandibular fractures occur in young males aged 16-30 years. As with all traumas, the history and examination cannot be over emphasised as diagnoses can be made with these tools. It is important when taking an accurate history to ascertain the mode and mechanism of injury (fall, punch, road traffic accident), and the magnitude and direction of the force involved (high or low velo...

~ vortex t~chnique capable of calculating the Rayleigh-Taylor instability to large amplitudes in inviscid, mcompresstble, layered flows is introduced. The results show the formation of a steady-state bubble at large times, whose velocity is in agreement with the theory of BirkhotT and Carter. It is shown that the spike acceleration can exceed free fall, as suggested recently by MenikotT and Zem...

The Confidence project is designed to support independent living of the elderly. The main goal of the project is reconstructing the user’s posture to detect falls in real time and to detect other abnormalities in behavior. This paper presents a survey of methods for fall detection and activity recognition and discusses how suitable they are for the Confidence project. The presented methods use ...

Most published reports of a floating clavicle consist of a dislocation of both ends of the clavicle and are associated with a high-energy injury. We report a 71 year old patient with a fracture of the medial end of the clavicle with anterior sternoclavicular dislocation and a nondisplaced fracture of the lateral end of the same clavicle distal to the insertion of coracoclavicular ligaments due ...
