01 Dec 2008TL;DR: Comparison of sub-word based methods for spoken term detection (STD) task and phone recognition and two constrained methods of multigram training found that the proposed method improves the phone accuracy more than 9% relative and STD accuracyMore than 7% relative.
Abstract: This paper deals with comparison of sub-word based methods for spoken term detection (STD) task and phone recognition. The sub-word units are needed for search for out-of-vocabulary words. We compared words, phones and multigrams. The maximal length and pruning of multigrams were investigated first. Then two constrained methods of multigram training were proposed. We evaluated on the NIST STD06 dev-set CTS data. The conclusion is that the proposed method improves the phone accuracy more than 9% relative and STD accuracy more than 7% relative.

TL;DR: A GPU accelerated toolbox for shaping the light propagation through multimode fibre using a spatial light modulator (SLM) and can be readily used to acquire transformation matrix and implement beam-shaping in any other linear optical system.
Abstract: We present a GPU accelerated toolbox for shaping the light propagation through multimode fibre using a spatial light modulator (SLM). The light is modulated before being coupled to the proximal end of the fibre in order to achieve arbitrary light patterns at the distal end of the fibre. First, the toolbox optimises the acquisition time of the transformation matrix of the fibre by synchronous operation of CCD and SLM. Second, it uses the acquired transformation matrix retained within the GPU memory to design, in real-time, the desired holographic mask for on-the-fly modulation of the output light field. We demonstrate the functionality of the toolbox by acquiring the transformation matrix at the maximum refresh rate of the SLM - 204Hz, and using it to display an on-demand oriented cube, at the distal end of the fibre. The user-controlled orientation of the cube and the corresponding holographic mask are obtained in 20ms intervals. Deleterious interference effects between the neighbouring points are eliminated by incorporating an acousto-optic deflector (AOD) into the system. We remark that the usage of the toolbox is not limited to multimode fibres and can be readily used to acquire transformation matrix and implement beam-shaping in any other linear optical system.

TL;DR: The findings suggest that an appropriate synovial fluid composition should be represented in a simulated body fluid in order to evaluate an implant material and subsequently to conduct biotribology tests.
Abstract: Biological components of synovial fluid and their concentration play a crucial role in the lubrication mechanism of artificial joints, particularly boundary lubrication. The purpose of this review was to summarise and critically analyse the lubrication mechanism and their tribological outcomes to artificial joints. Thirteen papers published between 01/01/2003 and 28/02/2013 met the inclusion criteria for the review. Four major biological components of synovial fluid (albumin, globulin, hyaluronic acid and lubricin) were found to have an influence on film thickness, friction coefficient and wear rate. The role of these components was reported to be varied, depending on not only their composition and concentration but also surface material properties, wettability, temperature and pressure. The findings suggest that an appropriate synovial fluid composition should be represented in a simulated body fluid in order to evaluate an implant material and subsequently to conduct biotribology tests.

TL;DR: In this paper, the PSPICE models of current-and flux-controlled meminductors are described, which consist of two parts, one representing the state-space description of the memory effect of the device, and the other part is an inductor whose inductance depends on the system state.
Abstract: PSPICE models of current- and flux-controlled meminductor are described. The models consist of two parts, one of which represents the state-space description of the memory effect of the device, and the other part is an inductor whose inductance depends on the system state. The basic fingerprints of the meminductor, i.e. the flux---current pinched hysteresis loops, the unambiguous constitutive relation between the time integral of flux and electric charge, and identical zero-crossing points of flux and current waveforms are demonstrated on the example of current-controlled meminductor.

21 Jul 2008TL;DR: This work proposes new antichain-based algorithms for checking universality and inclusion of nondeterministic tree automata (NTA) and implements these algorithms in a prototype tool and experiments show that they provide improvement over the traditional determinisa tion-based approaches.
Abstract: We propose new antichain-based algorithms for checking universality and inclusion of nondeterministic tree automata (NTA). We have implemented these algorithms in a prototype tool and our experiments show that they provide a significant improvement over the traditional determinisation-based approaches. We use our antichain-based inclusion checking algorithm to build an abstract regular tree model checking framework based entirely on NTA. We show the significantly improved efficiency of this framework through a series of experiments with verifying various programs over dynamic linked tree-shaped data structures.
