Mixtures of truncated exponentials (MTE) potentials are an alternative to discretization for solving hybrid Bayesian networks. Any probability density function (PDF) can be approximated with an MTE potential, which can always be marginalized in closed form. This allows propagation to be done exactly using the Shenoy-Shafer architecture for computing marginals, with no restrictions on the constr...

In this paper a new algorithm to detect hybrid periodic orbits of autonomous hybrid dynamical system is developed. Conventional Newton algorithm is modified so that it suits to the analysis of Poincaré return map of hybrid dynamical systems that include multiple phases (modes) and discrete jumps. Then, the algorithm is applied to a specific example; planar one-legged robot model having a spring...

Oscillator phase noise (PHN) and carrier frequency offset (CFO) can adversely impact the performance of orthogonal frequency division multiplexing (OFDM) systems since they can result in inter carrier interference and rotation of the signal constellation. In this paper, we propose an expectation conditional maximization (ECM) based algorithm for joint estimation of channel, PHN, and CFO in OFDM...

To replace the film recording aspect of performing optical correlation, conventional real-time joint-transform correlation (JTC) optical systems make use of a spatial light modulator (SLM) located in the Fourier plane to record the joint-transform power spectrum (JPS) to achieve real-time processing. The use of an SLM in the Fourier plane, however, is a major drawback in these systems because S...

Principal Components Analysis (PCA) being the most optimal linear mapper in Least-Squares (LS) sense has been predominantly used in subspace-based signal processing methods. In system identification problem, optimal subspace projections must span the joint space of the input and output of the unknown system. In this scenario, subspaces determined by the principal components of the input or the ...

The quasiparticle band structures and fundamental energy gaps of the rock-salt (rs), zinc-blende (zb), and wurtzite (wz) polymorphs of CaO and AlN are calculated within the G0W0 approximation on top of a selfconsistent solution of the generalized Kohn–Sham equation with the hybrid functional HSE03. Based on these reliable electronic structures, the dielectric functions of rs-CaO, zb-AlN, and wz...

Composite to steel joints as important components of ships are gradually found in the marine industry. The purpose of this study is to investigate mechanical performance and optimization methods of the composite sandwich to steel joints. The main emphasis was placed on the mechanical properties of a hybrid joint between a sandwich glass fibre reinforced plastic superstructure and a steel main h...

This article presents methods for robust and efficient communication over wireless channels. Both benefits and limitations of the classical approach of separate source and channel coding are discussed. Joint source-channel coding (JSCC) is presented as the most promising scheme for communication of analogue sources over wireless channels, due to its ability to cope with varying channel qualitie...

Space robots are an effective resource for astronauts working in a dangerous space environment. This paper proposes and implements a system to validate the performance of robot movement in space. A humanoid robot was designed with a vision-based self-calibration and navigation system. In addition, a path planning method was proposed to minimize joint torque. Simple gravity-compensation equipmen...

aim: abnormal joint mobility is an important factor in movement dysfunction and physical disability. a general lack of descriptive details exists for measurements of hip rotation range of motion (rom). this study was designed to establish the influence of hip position on active and passive range of motion of the hip in external and internal rotation(ext & int rot). material & methods: ...
