This paper presents <i>Xetal-Pro</i> SIMD processor, which is based on <i>Xetal-II</i>, one of the most computational-efficient (in terms of GOPS/Watt) processors available today. <i>Xetal-Pro</i> supports ultra wide <i>V</i><sub><i>DD</i></sub> scaling from nominal supply to the sub-threshold region. Although aggressive <i>V</i><sub><i>DD</i></sub> scaling(More)
Visual servoing has been proven to obtain better performance than mechanical encoders for position acquisition. However, the often computationally intensive vision algorithms and the ever growing demands for higher frame rate make its realization very challenging. This work performs a case study on a typical industrial application, organic light emitting(More)
We explore the Ziptronix Direct Bond Interconnect (DBI) technology [2] for the integration of sensors and readout integrated circuits (ROICs) for high energy physics. The technology utilizes an oxide bond to form a robust mechanical connection between layers which serves to assist with the formation of metallic interlayer connections. We report on testing(More)
Visual servoing applies image sensors instead of mechanical encoders for position acquisition. It can achieve higher resolutions than mechanical encoders at comparable cost. However, visual servoing is computation intensive. Special purpose hardware is often required. This work performs a case study on organic light emitting diode (OLED) manufacturing, a(More)
Results are reported on the transverse target-spin asymmetry associated with deeply virtual Compton scattering on the proton, extracted from the data accumulated by the HERMES experiment in the years 2002-2004. By comparing the HERMES results and theoretical predications based on a phenomenological model of generalized parton distributions, a(More)
Visual servoing has been proven to obtain better performance than encoders at comparable cost. However, the often computationally intensive vision algorithms and the ever growing demands for higher frame rate make its realization very challenging.

Solution-processed hybrid perovskite of CH3NH3PbI3 (MAPbI3) exhibits an abnormal luminescence behavior at around the tetragonal-orthorhombic phase transition temperature. The combination of time resolved photoluminescence (PL), variable excitation power PL, and variable-temperature X-ray diffraction (XRD) allows us to clearly interpret the abnormal(More)
This paper presents direct methods for vision-based control for the application of industrial inkjet printing. In this, visual control is designed with a direct coupling between camera measurements and joint motion. Traditional visual servoing commonly has a slow visual update rate and needs an additional local joint controller to guarantee stability. By(More)
Recent advances in Graphics Processing Units (GPUs) provide opportunities to exploit GPUs for non-graphics applications. Scientific computation is inherently parallel, which is a good candidate to utilize the computing power of GPUs. This report investigates QR factorization, which is an important building block of scientific computation. We analyze(More)
