After Section 404 of the Sarbanes-Oxley Act was released, developing an effective computer auditing system became critical for management and auditors. In this study, the researchers used Gowin's Vee, raised as a research strategy by Novak and Gowin (1984). On the theoretical side, the researchers arranged documents and employed an expert questionnaire to(More)
—In this paper we present an efficient block-based fragile watermarking system for tamper localization and recovery of images. We apply the Cyclic Redundancy Checksum (CRC) to authenticate the feature of a block stored in a pair of mapping blocks. The proposed scheme localizes the tampered area irrespective of the gray value, and the detection strategy is(More)
Human body tracking has received increasing attention in recent years due to its broad applicability. Among these tracking algorithms, the particle filter is considered an effective approach for human motion tracking. However, it suffers from the degeneracy problem and considerable computational burden. This paper presents a novel 3D model-based tracking(More)
BACKGROUND, AIMS AND SCOPE This research attempted to identify the dominant factors simultaneously affecting the airborne concentrations of five air pollutants with principal component analysis and to determine the meteorologically related parameters that cause severe air-pollution events. According to the definition of subPSI and PSI values through the(More)
BACKGROUND Since the 1970s, at least 200 hectares (ha) of farm-land has been polluted by the heavy metal cadmium (Cd). Consequently, the Cd pollution has led to contaminate the rice production and caused acute social panic. According to the recent investigation results performed by the Taiwan Environmental Protection Administration (TEPA), it is indicated(More)
