A numerical impact study is presented on a Formula Student (FS) racing car carbon composite nose cone. The effect of material model and model parameter selection on the numerical deceleration curves is discussed in light of the experimental deceleration data. The models show reasonable correlation in terms of the shape of the deceleration-displacement curves but do not match the peak decelerati...

The experimental investigation on a 60 apex-angle is carried out to study feasibility of simultaneous measurement of drag and aerodynamic heating in a shock tunnel. A three-component accelerometer balance system is used to measure the drag whereas platinum thin film gauges are used for heating rate measurements on the surface of the blunt cone model. Since every ground test and flight test data...

Tricho-rhino-phalangeal syndrome type I (TRPS I) is characterized by a bulbous nose, sparse hair and epiphyseal coning. Autosomal dominant and recessive transmission are suggested. The presence of cone-shaped epiphyses, the major complaint of patients due to swelling over the phalangeal joints, requires differential diagnosis among various syndromes. This paper, describing a ten-year-old girl w...

A nose cone is the conically shaped tip part of a missile, bomb or aircraft, used to regulate behavior oncoming airflow and minimize drag. In this study, effects different designs on trajectory impact angle smart fire extinguishing ammunition were investigated. For purpose, three types with profiles designed: spherically blunted conic cone, tangent ogive truncated cone. virtual wind tunnel was ...

UNLABELLED OBJECTIVES : A non-invasive immobilization system consisting of a thermoplastic mask with image-guidance using cone-beam CT (CBCT) and infrared (IR) tracking has been developed to ensure minimal inter- and intra-fractional movement during Gamma Knife radiosurgery. Prior to clinical use for patients on a Gamma Knife, this study clinically evaluates the accuracy and stability of this n...

Abstract This paper deals with the analysis of fluid flow around bluff bodies using computational dynamics. Two-dimensional rectangular body, semi-circular tip, triangular tip and elliptical nose cone shapes have been considered in paper. The are analysed at various Mach numbers, ranging from 1.5 to 10. aerodynamic characteristics like Drag coefficient drag force investigated. Also, formation s...

Adults use eye contact as a cue to the mental and emotional states of others. Here, we examined developmental changes in the ability to discriminate between eye contact and averted gaze. Children (6-, 8-, 10-, and 14-year-olds) and adults (n=18/age) viewed photographs of a model fixating the center of a camera lens and a series of positions to the left/right or upward/downward and judged whethe...

Acrodysostosis is characterized by distinctive facial features and severe brachydactyly. Mutations in PRKAR1A or PDE4D are known to be responsible for this disease. Cases of hormonal resistance have been reported, particularly in patients with PRKAR1A mutations. The physical characteristics and endocrine function of pseudohypoparathyroidism type Ia is known to resemble acrodysostosis. We report...

The maxillary sinuses diseases are an actual clinical problem today. aim of our study was to determine the frequency pathology different origin and its age dynamics in adults.
 500 series anonymized tomograms adults were analyzed: 22-35 years (1st group) 36-60 (2nd group men) 36-55 women). Cone-beam computed tomography (CT) nose, paranasal sinuses, upper jaw performed on a Point 3D Combi c...
