This paper proposes a SPAD array sensor based on breakdown pixel extraction architecture with background readout for scintillation detectors. The proposed architecture extracts the addresses of only the breakdown pixels during the exposure time of the next frame. Therefore, this sensor minimizes the dead time and improve the readout efficiency. A SPAD array sensor was fabricated in a 0.18 μm CMOS...

The availability and amount of sequenced genomes have been rapidly growing in recent years because of the adoption of next-generation sequencing (NGS) technologies that enable high-throughput short-read generation at highly competitive cost. Since this trend is expected to continue in the foreseeable future, the design and implementation of efficient and scalable NGS bioinformatics algorithms are...
Neuronal tuning property such as preferred direction and modulation depth could change gradually or abruptly in brain machine interface (BMI). The decoding performance will decay in static algorithms where dynamic neuronal tuning property is regarded as stationary. Many adaptive algorithms have been proposed to update the time-varying decoding parameter with main consideration on the decoding performance,...
This paper presents a circularly polarized millimeter wave antenna by using a tapered polarizer. The polarizer consists of several air and dielectric slabs, which can be used to switch the polarization of the antenna from linear polarization into circularly polarization. Besides, with the tapered shaped, the polarizer can decrease the sidelobe of the radiation pattern and increase the gain of the...
Balanced/balanced-to-single-ended networks have been used widely in modern communication systems due to their ability of easy connection in balanced systems as well as differential-mode power division, common-mode suppression. Furthermore, filtering balanced or balanced-to-single-ended networks have become increasingly of interest for the advantages of multiple functions and compactness. In this paper,...
The progress of next-generation sequencing has a major impact on medical and genomic research. This technology can now produce billions of short DNA fragments (reads) in a single run. One of the most demanding computational problems used by almost every sequencing pipeline is short-read alignment; i.e. determining where each fragment originated from in the original genome. Most current solutions are...
Compressive sensing (CS) is a promising technology for realizing energy-efficient wireless sensors for long-term health monitoring. However, conventional model-driven CS frameworks suffer from limited compression ratio and reconstruction quality when dealing with physiological signals due to inaccurate models and the overlook of individual variability. In this paper, we propose a data-driven CS framework...

Computer generated forces (CGFs) are autonomous or semi-autonomous actors within military, simulation based, training and analyzing applications. Rapid, realistic and adaptive behavior modeling for CGFs is imperative and challenging. Traditional modeling approaches like rule-based script usually need time-consuming, repetitive endeavor and result in rigid, predictable behavior performance. Recent...

Multiple object tracking has been modelled as minimum cost network flow (MCNF) optimization problem recently. It is one of the most popular tracking-by-detection algorithm. MCNF is particularly effective due to its simple model and optimal solutions. However, complex scenarios, such as noisy detections and multi-objective interactions, make it difficult to track multi-objects in consecutive frames...

Sensemaking is described as the process in which people collect, organize and create representations of information, all centered around some problem they need to understand. People often get lost when solving complicated tasks using big datasets over long periods of exploration and analysis. They may forget what they have done, are unaware of where they are in the context of the overall task, and...
