Thermal imaging is a nondestructive testing method for monitoring internal material changes that are indicated by changes in an object’s surface temperature. In this study, field observation using thermographs was applied to monitor and analyze the breach process of large-scale earth dams. The earth dam test site was Landao Creek in Nantou County, Taiwan. Four field tests were performed to monitor...
In this paper, we improve the direction finding accuracy for shortwave fixed stations located in imperfect environment. A correction method of direction finding data is proposed based on least square algorithm. Firstly, we establish the mathematical model of the relationship between real azimuthal angles and errors according to the statistical features of direction finding data. Then we design model...
In a recent study, we have shown that the mixtures of graphene oxide (GO) nanosheets and Pluronic F-127 (PLU) polymers (GO-PLU) exhibit superior antimicrobial activity compared to GO alone on physiologically naïve bacteria challenged with hypoosmotic stress, particularly on Gram-negative species. Further, we have more recently demonstrated that the antibacterial activity of GO (alone) is significantly...
Distributed data stream processing has become an increasingly popular computational framework due to many emerging applications which require real-time processing of data such as dynamic content delivery and security event analysis. These distributed data stream processing applications are often run on shared, multi-tenant clusters as companies try to consolidate from dedicated clusters for each application...
Mosaic is a low-cost sensing system for city scale air quality monitoring. Mosaic is able to monitor city scale air quality with low costs by deploying customized sensors on moving vehicles. Objectives of this demo are to show how our customized low-cost sensors work and present the three-layer air quality monitoring system. Details about the node design can be found in [1] which will be presented...
This study proposes a real-time abnormal heartbeat detection and emergency system for helping users to obtain immediate rescue and treatment in a short period of time when they suffer from severe heart disease, for example, acute myocardial infarction (MI) or fatal malignant arrhythmia. The proposed system can detect abnormal heartbeat waveforms and automatically send out emergency signals. The detection...
Error correction code (ECC) and built-in self-repair (BISR) schemes have been wildly used for improving the yield and reliability of memories. Many built-in redundancy-analysis (BIRA) algorithms and ECC schemes have been reported before. However, most of them focus on either BIRA algorithms or ECC schemes. In this paper, we propose an ECC-Enhanced Memory Repair (EEMR) scheme for yield improvement...
Traffic Emergency Command System is a vital part of City Emergency Command System. Besides, studies on the emergency processing procedures are the foundation of studying Emergency Command System. The thesis is going to introduce the concept of HTCPN, elaborating its advantages in Emergency Command System. The thesis gives a detailed explanation of HTCPN modeling procedures and has done simulation...
Climate change is one of the driving forces behind a new wave of energy management systems. Most of the currently available energy management systems in domestic environment are concerned with real-time energy consumption monitoring, and display of statistical and real time data of energy consumption. Although these systems play a crucial role in providing a detailed picture of energy consumption...
In this paper, we present a low-cost driving assistant system which can provide the surrounding image of a vehicle in a bird's-eye view. By implementing a fast image stitching algorithm on an embedded platform, this system can generate the around-vehicle view in real time from four fisheye cameras mounted around the vehicle. Moreover, we also propose a dynamic boundary determination method to allow...
A new cell culture system is demonstrated in this paper. This system includes a culture incubator with a compact optical monitoring module and an electro-chemical impedance sensor (ECIS) chip with gelatin micro patterns attracting living cells selectively. We provided a platform with a shorter observation interval of 4 hours and a finer line width of electrodes of sensor chips than the prior art in...
In order to manage a service to meet the agreed upon SLA, it is important to design a service of the required capacity and to monitor the service thereafter for violations at runtime. This objective can be achieved by translating SLOs specified in the SLA into lower-level policies that can then be used for design and enforcement purposes. Such design and operational policies are often constraints...
As system-on-chip (SoC) becomes prevalent in the intelligent system applications, the reliability issue of SoC is getting more attention in the design industry while the SoC fabrication enters the very deep submicron technology. In this study, we present a new approach of system-bus fault injection in SystemC design platform, which can be used to assist us in performing the FMEA procedure during the...
Mineral filler-reinforced polymer is an important family of polymers designed to achieve high mechanical impact strength. The state of mineral filler dispersion in a polymer matrix strongly affects the mechanical properties of the product and is an important piece of information for the extrusion-based fabrication process. In this work, a measurement system composed of 2 ultrasonic sensors, 3 pressure...
