The role of radiative cooling during the evolution of a bow shock was studied in laboratory-astrophysics experiments that are scalable to bow shocks present in jets from young stellar objects. The laboratory bow shock is formed during the collision of two counterstreaming, supersonic plasma jets produced by an opposing pair of radial foil Z-pinches driven by the current pulse from the MAGPIE pu...
We developed an ”augmented violin”, i.e. an acoustic instrument with added gesture capture capabilities to control electronic processes. We report here gesture analysis we performed on three different bow strokes, Détaché, Martelé and Spiccato, using this augmented violin. Different features based on velocity and acceleration were considered. A linear discriminant analysis has been performed to...
A commuted-synthesis model for bowed strings is driven by a separate nonlinear model of bowed-string dynamics. This gives the desirable combination of a full range of complex bow-string interaction behavior together with an efficiently implemented body resonator. A “single-hair bow” may control a pulsed-noise version which provide the effects of multiple bow hairs. The pulsed noise may also inc...
This paper presents a new framework for visual bag-of-words (BOW) refinement and reduction to overcome the drawbacks associated with the visual BOW model which has been widely used for image classification. Although very influential in the literature, the traditional visual BOW model has two distinct drawbacks. Firstly, for efficiency purposes, the visual vocabulary is commonly constructed by d...
A parameter study is undertaken for steady symmetrical planar field-aligned MHD bow shock flows around a perfectly conducting cylinder. For sets of values of the inflow plasma β and Alfvénic Mach number (MA) which allow for switch-on shocks, a numerical solution is obtained which exhibits a complex bow shock shape and topology with multiple shock fronts and a dimpled leading front. For paramete...
abstract introduction: balance is one of the most important contexts in ageing. improving balance in middle age can prevent falling down in elderly which impose the financial and mental costs to society. imbalance between dominant and non-dominant leg can lead to some problems. that’s way; studying effects of similar exercise on dominant and non-dominant legs of body can prevent problems caus...
This paper describes the development of a virtual violin bow haptic human-computer interface, which senses bow position with encoders, to drive bowed-string physical model synthesis, while engaging servomotors, to simulate the haptic feedback of a violin bow on a string. Construction of the hardware and programming of the software are discussed, as well as the motivation for building the instru...
The bag of visual words (BOW) model is an efficient image representation technique for image categorisation and annotation tasks. Building good visual vocabularies, from automatically extracted image feature vectors, produces discriminative visual words which can improve the accuracy of image categorisation tasks. Most approaches that use the BOW model in categorising images ignore useful infor...
BACKGROUND Cephalomedullary Nail (CMN) is seen as the mainstay of internal fixation in femoral fractures. The purpose of the study was to present an accurate calculation method by simulating diverse anterior bow femoral models with finite element software. We hypothesized that anterior cortical penetration in distal femur would occur in patients whose femoral anterior bow was identified as too ...
