Image super-resolution is a process to enhance image resolution. It is widely used in medical imaging, satellite imaging, target recognition, etc. In this paper, we conduct continuous modeling and assume that the unknown image intensity function is defined on a continuous domain and belongs to a space with a redundant basis. We propose a new iterative model for single image super-resolution bas...

This work describes a simple optical method for obtaining, in a single still-capture image, the continuous absorbance spectra of samples at multiple locations of microsystems. This technique uses an unmodified bright-field microscope, an array of microlenses, and a diffraction grating to disperse the light transmitted by samples of 10- to 500-microm dimensions. By analyzing in a single image th...

CsI(Na), CsI(T1) and NaI(T1) scintillators coupled through optical fibers were investigated with simulations and measurements to evaluate their potential as gamma imaging intraoperative probes. Three coupling methods were employed: discrete crystals coupled one-to-one with the fibers; discrete crystals coupled through a light diffuser to an unmatched fiber array; and continuous crystals coupled...

A high resolution analog to digital converter (ADC) is presented and it’s dedicated to neural recording systems. By employing two continuous time incremental sigmadelta(I∑∆) ADC in a pipeline configuration, without sacrificing the conversion rate the proposed ADC can obtain high resolution. This two-step architecture is furthermore power efficient, as the resolution need for the incremental ADC...

The mechanical wiring between cells and their surroundings is fundamental to the regulation of complex biological processes during tissue development, repair or pathology. Traction force microscopy (TFM) enables determination of the actuating forces. Despite progress, important limitations with intrusion effects in low resolution 2D pillar-based methods or disruptive intermediate steps of cell ...

We propose a Brillouin optical correlation-domain reflectometry (BOCDR), which can measure the distribution of strain and/or temperature along an optical fiber from a single end, by detecting spontaneous Brillouin scattering with controlling the interference of continuous lightwaves. In a pulse-based conventional Brillouin optical time-domain reflectometry (BOTDR), it is difficult in principle ...

Tonal music is characterized by a continuous flow of tension and resolution. This flow of tension and resolution is closely related to processes of expectancy and prediction and is a key mediator of music-evoked emotions. However, the neural correlates of subjectively experienced tension and resolution have not yet been investigated. We acquired continuous ratings of musical tension for four pi...

The series of joint U.S.-Japan spaceborne scatterometers missions to provide continuous measurements of ocean wind vectors is reviewed. Examples of the scientific impact of the continuous effort in improving spatial resolution and coverage are provided,. The plan for future missions is reviewed.

Wireless base station and VDSL transceiver require A/D converter with signal bandwidth more than 10MHz and resolution in the range of 12-14bits. Continuous-time Σ∆ A/D converter has the advantage of possible high signal bandwidth as well as low power consumption compared with discrete time counterpart. In this project, our target is to design a 12MHz-signal bandwidth continuous time Σ∆ A/D conv...

In this paper we address the problem of drawing planar graphs with circular arcs while maintaining good angular resolution and small drawing area. We present a lower bound on the area of drawings in which edges are drawn using exactly one circular arc. We also give an algorithm for drawing n-vertex planar graphs such that the edges are sequences of two continuous circular arcs. The algorithm ru...
