In recent years, Blockchain technology has been highly valued, and the related applications have begun to be developed in large numbers. A smart contract is a software component encompass business logics and transactions that run on a blockchain. Thus, verifying whether the contract logics fully reflect the business requirements are one of the most important software engineering issues in blockchain...
We can perceive the advent of smart living spaces attributed to the fast emerging of IoT (Internet of Things) technologies. By combining with the blockchain technology, many innovative business models can be brought into reality. This paper aims to report our recent progress in investigating the architectural issues for realizing blockchain-driven IoT services. In particular, we present and discuss...
In recent years, many near-infrared systems are used to detect breast tumor. However, the large instrument size and unfriendly interface make them hard to be accessed by users. In this paper, we proposed a portable, wireless and user friendly breast imaging system for breast tumor early detection. The system is implemented on self-designed platform combined with front-end sensors, DOT chip by TSMC...
Recently there have been many studies regarding pulse wave velocity (PWV) produced by near-infrared light. However, these studies have used multiple probes with the synchronization problem. This paper proposed a new detecting method to measure PWV on a radial artery with multiple channels in one front-end sensor array. The system was implemented on a MSP430F169 platform and the PWV result was transmitted...
Diffuse Optical Tomography (DOT) is a novel medical image technology with non-invasive method in the recent years. However, it has not been popular in clinical practice. In this work, a custom signal processing engine for Continuous Wave (CW) DOT is proposed, for the forward and inverse problem in the calculating procedure. To achieve the goals of small hardware size, low power consumption, and popularity,...
In recent years, many studies of 2-D oxygen saturation distribution reconstruction have provided easy access to human brain activity regions. However, only a few research focus on the home health care system using this technique. In this paper, we proposed a portable, low cost and real-time distribution reconstruction system of oxygen saturation in 2-D to make diagnosis at home possible. The system...
In this paper, a digital signal processing system for image reconstruction of continuous wave diffusion optical tomography (CW-DOT) is proposed. Optical tomography systems employing near-infrared light can be used to detect oxygen concentration and impurities such as breast cancer in the human body. The proposed CW-DOT architecture is a truly appropriate system for further enhancing the possibility...
Liver fibrosis can be induced by environmental chemicals or toxicants, and finally stimulates fibrogenic cytokines expression, such as transforming growth factor-β (TGF-β) and its downstream mediator connective tissue growth factor (CTGF). 15-deoxy-Δ 12,14 -prostaglandin J 2 (15d-PGJ 2 ) is a metabolite of arachidonic acid, can act as a peroxisome proliferator-activated receptor...
