The bag-of-words (BoW) method has been used widely in language modelling and information retrieval. A document is expressed as a group of words disregarding the grammar and the order of word information. A typical BoW method is latent semantic analysis (LSA), which maps the words and documents onto the vectors in LSA space. In this paper, the concept of BoW is extended to Bag-of-Word Pairs (BoW...
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...
ترمیم asd primum درافراد با رنج سنی متفاوت معمولا در برگیرنده عوارض کوتاه مدت و تاخیری می باشد. مابصورت مطالعه توصیفی و گذشته نگر در صدد تعیین نتایج جراحی با تکنیک اصلاح شده در بیماران با نقص (partial a-v canal defect)sdprimum در مراکز جراحی قلب کرمانشاه از سال 1373 تا مهرماه 1380 می باشیم.
در این پایان نامه، رفتار استاتیک ساختارهای آرایه ای پادهدایت vcsel، شبیه سازی و آنالیز شده است. برای تحلیل مشخصه های نوری (میدان نزدیک و دور)، گرمایی (توزیع دما) و اکتریکی (چگالی حامل) ساختار، از مدل نسبتاً جامعی که شامل معادلات موج، پخش حامل و انتقال گرما و اثرات متقابل پدیده های نوری، گرمایی و الکتریکی است، استفاده گردیده است. دو گروه از vcselهای آرایه ای پادهدایت، بررسی شده اند: آرای? تزویج ...
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...
