Face recognition using representation based classification (RC) is a new hot technique in recent years. However, the recognition rate degrades when the misalignment problem occurs, especially in unconstrained environment. In this paper, a novel framework of RC multi-view face recognition is proposed. A 3D reference model is used for projection matrix approximating. The train frontal face samples are...
Flow phantoms with anatomically realistic geometry and high acoustic compatibility are valuable investigative tools in vascular ultrasound studies. Here, we present a new framework to fabricate ultrasound-compatible flow phantoms to replicate human vasculature that is tortuous, nonplanar, and branching in nature. This framework is based upon the integration of rapid prototyping and investment casting...
As a major application domain of vascular ultrasound, the carotid artery has long been the subject of anthropomorphic phantom design. It is nevertheless not trivial to develop walled carotid phantoms that are compatible for use in integrative imaging of carotid wall motion and flow dynamics. In this paper, we present a novel phantom design protocol that can enable efficient fabrication of walled carotid...
Recently, permanent magnet (PM)-brushless direct current motors (BLDCMs) have been widely used in high-performance motor drive applications, thanks to their many attractive advantages, such as higher power and torque density and efficiency, simpler motor assembly and maintenance, lower cost, acoustic noise, and vibration. However, due to cost increase rapidly and restricted exploitation of rare earth...
Stator bar transposition is a key technology in the electromagnetic design of water-cooled turbo-generator. Transposition bars are located in the slot within the scope of different leakage magnetic fields, circulating current and additional loss are produced among the parallel strands connected by the end nose, which bring the local overheating and seriously affect the operation safety. In engineering,...
A novel technique has been developed under a DNDO SBIR Program to improve the quality and availability of law enforcement and first responder training in the use of Preventative Radiological/Nuclear Detection (PRND) equipment. This training method is implemented in a software system designated as RAILS (Realistic and Adaptive Interactive Learning System), which allows trainees to practice finding,...
In this work, new halo profile engineering is proposed to suppress the threshold voltage variation (σVt) caused by discrete random dopant fluctuation (RDF). An in-house 3D atomistic numerical simulation tool is utilized to assess nMOSFETs σVt caused by RDF for a HK/MG process. The results show that σVt can be effectively suppressed by 10% by optimizing rotation and tilt angles of the halo implant.
We present an in-house tool to simulate random dopant fluctuation effects on nano-scale devices with nonuniform channel doping profiles. A novel dopant discretization scheme using Poisson statistics that can achieve self-consistent median parametric values (e.g. average channel concentration) with deterministic device simulations was introduced. This capability was deployed to study the variability...
