Hybrid imaging techniques utilize couplings of physical modalities – they are called hybrid, because, typically, the excitation and measurement quantities belong to different modalities. Recently there has been an enormous research interest in this area because these methods promise very high resolution. In this paper we give a review on hybrid tomography methods for electrical conductivity ima...

In this paper, an experiment is conducted to optimize the kerf width of wire electrical discharge machining (WEDM) on Aluminum hybrid composite with Zinc coated brass wire using Taguchi method. Aluminum metal matrix composites (MMCs) reinforced with silicon carbide particulate (SiCp) find several applications due to their improved mechanical properties for a wide variety of aerospace and automo...

This paper proposes a feed-forward control model for SWB6105 parallel hybrid electric urban bus (PHEUB) by using Matlab/Simulink. In order to optimize the fuel economy, balance the battery state of charge (SOC), and satisfy the requirements of the vehicle performance and drivability as well, a logic threshold torque distribution control strategy (LTTDCS) incorporating with an instantaneous opti...

Hybrid imaging plays a central role in the diagnosis and management of a wide range of malignancies at all stages. In this article, we review the most pertinent historical developments, emerging clinical applications of novel radiotracers and imaging technologies, and potential implications for training and practice. This includes an overview of novel tracers for prostate, breast, and neuroendo...

Hybrid electric vehicles (HEVs) are an emerging technology for improving fuel economy and emissions. However, hybrid powertrains are expensive to manufacture because of the sophisticated electronics required. In particular, the motor and battery requirements must be carefully considered because of the cost and weight of these components. For this reason, it is important to conduct an upfront an...

STATEMENT OF THE PROBLEM In stress-bearing cavities, low fracture resistance adversely affects the longevity of the dental resin composite restorations. PURPOSE The aim of this in vitro study was to investigate the effect of glass fiber layering on the flexural strength of microfill and hybrid composites. MATERIALS AND METHODS Flexural test specimens (N = 75) were prepared according to Inte...

Hybrid imaging techniques provide enhanced visualization of biological targets by synergistically combining multiple imaging modalities, thereby providing information on specific aspects of structure and function, which is difficult to obtain by a single imaging modality. Advances in the field of hybrid imaging have resulted in the recent approval of PET/magnetic resonance (MR) imaging by the U...

The purpose of our study was to determine the value of different hybrid imaging combinations for the detection of focal and diffuse bone marrow infiltration in lymphoma. Patients with histologically proven lymphoma, who underwent both [18F]-FDG-PET/CT and whole-body MRI (including T1- and diffusion-weighted [DWI] sequences) within seven days, and a subsequent bone marrow biopsy, were retrospect...

Hybrid Monte Carlo (HMC) is a rigorous sampling method that uses molecular dynamics (MD) as a global Monte Carlo move. The acceptance rate of HMC decays exponentially with system size. The shadow hybrid Monte Carlo (SHMC) was previously introduced to reduce this performance degradation by sampling instead from the shadow Hamiltonian defined for MD when using a symplectic integrator. SHMC's perf...

We show, by means of numerical and analytical methods, that media with a repulsive nonlinearity which grows from the center to the periphery support a remarkable variety of previously unknown complex stationary and dynamical three-dimensional (3D) solitary-wave states. Peanut-shaped modulation profiles give rise to vertically symmetric and antisymmetric vortex states, and novel stationary hybri...
