This paper proposes a fault detection algorithm for a velocity controller using MRAC in the belt conveyor system of a fish processing line. In general terms, the fault detection algorithm utilizes an extended Kalman filter (EKF) based on a known mathematical model to estimate the state vector and compare computed residue values with a threshold value to determine fault condition. However, a system that models a belt conveyor system has some uncertain parameters. Thus, a fault detection algorithm based on the mathematical model with uncertain parameters can give false alarms or miss detection events. The following can be done to solve this issue: First, a velocity controller based on an MRAC has been designed to estimate uncertain parameters in the belt conveyor system and control belt conveyor velocity to track a reference input asymptotically. Second, an angular velocity output and a friction coefficient are chosen as the state vector and observation vector elements for the EKF. Third, process and observation vector functions are determined and the EKF is used to compute the residue value, which is then compared to a given threshold value to detect a fault. Finally, the simulation and experimental results are shown to verify the proposed algorithm’s effectiveness.

Research Articles : Trichoderma asperellum Chi42 Genes Encode Chitinase
( Nguyen Hoang Loc ),( Hoang Tan Quang ),( Nguyen Bao Hung ),( Nguyen Duc Huy ),( Truong Thi Bich Phuong ),( Tran Thi Thu Ha ) 한국균학회 2011 韓國菌學會誌 Vol.39 No.3
Four Trichoderma strains (CH2, SH16, PQ34, and TN42) were isolated from soil samples collected from Quang Tri and Thua Thien Hue provinces in Vietnam. The strains exhibited high chitinolytic secretion. Strain PQ34 formed the largest zone of chitinase-mediated clearance (> 4 cm in diameter) in agar containing 1% (w/v) colloidal chitin. Analysis of the internal transcribed spacer regions of these strains indicated that they were Trichoderma asperellum. The molecular weights of the chitinases were approximately 42 kDa. Chitinase genes (chi42) of T. asperellum strains TN42, CH2, SH16, and PQ34 were 98~99% homologous to the ech42 gene of T. harzianum CB-Pin-01 (accession No. DQ166036). The deduced amino acid sequences of both T. asperellum strains SH16 and TN42 shared 100% similarity.

Backgrounds/Aims: Parenchymal-sparing anatomical hepatectomy (Ps–AH) based on portal ramification of the right anterior section (RAS) is a new technique to avoid unnecessarily transecting too much liver parenchyma, especially in cases of major anatomical hepatectomy. Methods: We prospectively assessed 26 patients with primary hepatic malignancies having undergone major Ps–AH based on portal ramification of the RAS from August 2018 to August 2022 (48 months). The perioperative indications, clinical data, intra-operative index, pathological postoperative specimens, postoperative complications, and follow-up results were retrospectively evaluated. Results: Among the 26 patients analyzed, there was just one case that had intrahepatic cholangiocarcinoma The preoperative level of α– Fetoprotein was 25.2 ng/mL. All cases (100%) had Child–Pugh A liver function preoperatively. The ventral/dorsal RAS was preserved in 19 and 7 patients, respectively. The mean surgical margin was 6.2 mm. The mean surgical time was 228.5 minutes, while the mean blood loss was 255 mL. In pathology, 5 cases (19.2%) had microvascular invasion, and in the group of HCC patients, 92% of all cases had moderate or poor tumor differentiation. Six cases (23.1%) of postoperative complications were graded over III according to the Clavien–Dindo system, including in three patients resistant ascites or intra-abdominal abscess that required intervention. Conclusions: Parenchymal-sparing anatomical hepatectomy based on portal ramification of the RAS to achieve R0-resection was safe and effective, with favorable short-term outcomes. This technique can be used widely in clinical practice.
