Dynamic response characteristics of an innovative turretless low motion FPSO hull in central GoM ultra-deep waters

Zou, Jun Techno-Press 2022 Ocean systems engineering Vol.12 No.2

In oil and gas industry, FPSO concept is the most popular hull form and ship shaped hull form dominants the FPSO market. Only a non-ship-shaped hull in operations with minor market shares is the cylindrical FPSO hull with medium to small storage capability. To add contracting options and competitions to reduce field development costs, an innovative turretless low motion hull, eco-FPSO, with 1MM bbls oil storage capacity and suitable for installing topsides modulars and equipping with regular SCRs, was first introduced in Zou (2020a). Dynamic characteristic responses of the eco-FPSO compared to the traditional SS-FPSO hull and DD-Semi platform are presented and discussed in this paper, suitability and feasibility of the proposed hull have been demonstrated and validated through extensive analyses in 10-yrp, 100-yrp and 1,000-yrp hurricanes in ultra-deepwater central GoM.

Bingshuang Zou,김태우,최순철 대한치과교정학회 2005 대한치과교정학회지 Vol.35 No.5

본 연구는 안면비대칭이 있는 환자의 측두하악관절원반 형태와 위치를 평가하고 악관절내장증과 안명비대칭 간의 관계를 규명하기 위하여 시행되었다. 남자 10명 및 여자 27명으로 구성된 안명비대칭 환자 37명의 74개의 TMJ MRI를 사용하였으며, 대상 집단의 연령은 12세에서 44세까지의 범위로 평균 21.4세였다. 시상 및 두정 TMJ MRI를 최대감합위 및 최대개구위에서 채득한 후 부분전방변위, 전방변위, 회전 또는 측방 원반변위 등 원반변위의 종류를 기록하였으며, 원반의 모양, 위치, 그리고 원반의 변위 및 회전을 MRI tracing 상에서 판독하였다. 악관절내장증의 증상은 정상, 정복성 전방원반변위 (ADDR). 그리고 비정복성 전방원반변위(ADDNR)집단으로 분류하였으며, 환자는 양측성 정상. 편측 혹은 양측 내장증 집단으로 분류하였다. 약 70%의 환자에서 편측성 또는 양측성 내장증을 보였으며, 통계분석 결과 ADD. 특히 회전성 ADD가 변위측에서 더 높은 빈도로 나타났으나 반대측에서는 원반의 위치가 정상인 경우가 많았다 (p<0.01).변위측의 원반은 모양의 변형 및 하전방 변위를 유의하게 더 나타냈다. 그러나 반대쪽은 개구시 원반이 수직방향으로 과운동성이 관찰되었다. 이 연구는 안면비대칭 환자에서 ADD의 종류가 원반의 모양,경사,변위 각도,변위의 수직거리 및 회전각도와 연관이 있다는 것을 제시한다. The present study was conducted to examine the morphometrics and function of the disk on both sides among patients with facial asymmetry (FA) and to elucidate plausible correlations between internal derangement (ID) and FA. The sample was composed of 10 males and 27 females with FA. The disk status of all subjects was evaluated by biateral high resolution magnetic resonance scans in the sagittal (closed and open) and coronal (closed) planes. Five types of disk displacement were identified accordingly. The disk function was diagnosed as normal disk function, disk displacement with reduction, and disk displacement without reduction. The disk shape on sagittal MRI in closed position was classified as bi-concave, biplanar, funnel/hemiconvex, and deformed. The disk position, translation and rotation were also measured. The difference between the shifted side and non-shifted side was analyzed by statistical analysis. Approximately 70% of the patients in the present study showed unilateral or bilateral ID. It was found that anterior disk displacements (ADD), especially rotational ADD, occurred more frequently in the shifted side, while normal disk position was observed mainly in the non-shifted side(p<0.01). The disk of the shifted side showed significantly deformed configuration and inferior-anterior disk position. However, the disk of the non-deviated side showed hyper-mobility during jaw opening movement. These results demonstrate that in FA patients, the disks status of the shifted side is different from that of the non-shifted side, a phenomenon that could be correlated to facial asymmetry.

Yang Zou,XinPing Zou,XiZhi Li,Gang Guo,Peng Ji,Yan Wang,ShengLi Li,YaJing Wang,ZhiJun Cao 아세아·태평양축산학회 2018 Animal Bioscience Vol.31 No.3

Objective: The impact of forage feeding strategy on growth performance, ruminal fermentation and nutrient digestibility in post-weaning calves was investigated. Methods: Forty-five female Holstein calves (body weight [BW] = 79.79±0.38 kg) were enrolled in the 35-d study at one week after weaning and randomly assigned to one of three dietary treatments. All diets were fed as total mixed ration containing 60% (dry matter [DM] basis) of basal starter feed and 40% (DM basis) of forage, but varied in composition of forage source including i) alfalfa (40% DM, AH); ii) alfalfa hay (26.7% DM)+oat hay (13.3% DM; OH); iii) alfalfa hay (26.7% DM)+corn silage (13.3% DM; WS). Results: Dry matter intake was not different among treatment groups (p>0.05). However, BW (p<0.05) and average daily gain (p<0.05) of calves fed AH and OH were greater than WS-fed calves, whereas heart girth was greater in OH-fed calves than those fed AH and WS (p<0.05). Ruminal fermentation parameters including proportion of butyric acid, acetated-to-propionate ratio, concentration of total volatile fatty acid, protozoal protein, bacterial protein, and microbial protein in rumen were the highest in OH (p<0.05) and the lowest in WS. Compared with the AH and WS, feeding oat hay to postweaning calves increased crude protein digestibility (p<0.05), and decreased duration of diarrhea (p<0.05) and fecal index (p<0.05). Conclusion: Our results suggested that partially replacing alfalfa hay with oat hay improved ruminal fermentation, nitrogen utilization, and reduced incidence of diarrhea in post-weaning dairy calves.

Asymmetric Virtual Impedance for Improving Transient Stability of Grid-Forming Inverters Based on Virtual Reluctance Torque

Zhaoyue Zou,Chao Wu,Yong Wang,Yu Lu,Qiang Zou,Nannan Wang 전력전자학회 2023 ICPE(ISPE)논문집 Vol.2023 No.-

The grid-forming inverters have received much attention due to the great voltage and frequency support ability. However, a lot of transient instability phenomena have been reported to the grid-forming inverters. In order to improve the transient stability of grid-forming inverters, an asymmetric virtual impedance is proposed to simulate the reluctance torque of synchronous generator to increase to power transfer ability. Furthermore, the design of virtual impedance is considered from the dimensions of d axis and q axis respectively, and the effect of reluctance torque on the transient stability is shown from the perspectives of increasing power transfer margin and providing larger deceleration area. Finally, the simulation results are presented to validate the effectiveness of the proposed method.

Two-dimensional water seepage monitoring in concrete structures using smart aggregates

Zou, Dujian,Li, Weijie,Liu, Tiejun,Teng, Jun Techno-Press 2018 Structural monitoring and maintenance Vol.5 No.2

The presence of water inside concrete structures is an essential condition for the deterioration of the structures. The free water in the concrete pores and micro-cracks is the culprit for the durability related problems, such as alkali-aggregate reaction, carbonation, freeze-thaw damage, and corrosion of steel reinforcement. To ensure the integrity and safe operation of the concrete structures, it is very important to monitor water seepage inside the concrete. This paper presents the experimental investigation of water seepage monitoring in a concrete slab using piezoelectric-based smart aggregates. In the experimental setup, an $800mm{\times}800mm{\times}100mm$ concrete slab was fabricated with 15 SAs distributed inside the slab. The water seepage process was monitored through interrogating the SA pairs. In each SA pair, one SA was used as actuator to emit harmonic sine wave, and the other was used as sensor to receive the transmitted stress wave. The amplitudes of the received signals were able to indicate the water seepage process inside the concrete slab.

Zou Hongbo,Yang Qinhe,Chen Junting,Chai Yanhui 대한전기학회 2023 Journal of Electrical Engineering & Technology Vol.18 No.5

With the increasing complexity of the world energy structure, the uncertainty of the power system increases significantly, and the accuracy of the short-term power load forecasting is of great significance to the safe, economical and reliable operation of the power system. In order to further improve the accuracy of short-term power load forecasting, this paper innovatively combines the theories such as phase space reconstruction, empirical mode decomposition, and extreme learning machine to establish a new short-term power load forecasting model based on phase space reconstruction and EMD-ELM. The prediction results show that the root means square error, average relative error and global maximum relative error of the short-term power load forecasting model based on phase space reconstruction and EMD-ELM are much smaller than other forecasting models, which verifies the correctness and effectiveness of the short-term load forecasting method.

Zou, Shi-geng,Zhi, Ai-min,Zhou, Xiang-yan,Zuo, Jian-jun,Zhang, Yan,Huang, Zhi-yi,Xu, Ping-Wen,Feng, Ding-yuan Asian Australasian Association of Animal Productio 2009 Animal Bioscience Vol.22 No.5

The goal of this study was to elucidate the expression and segmental distribution of the glomerular cationic amino acid metabolism transporter-2 (CAT-2) and thus to improve our understanding of porcine cationic amino acid transporters and amino acid absorption. Porcine CAT-2 was cloned, sequenced and characterized. The predicted amino acid sequence of porcine CAT-2 shared 86.1% and 92.1% identity with human and mouse CAT-2A, respectively. The tissue distribution patterns and ontogenic changes of CAT-2 mRNAs were determined by real-time Q-PCR. The results showed that porcine CAT-2 was highly expressed in the heart and intestinal tract (duodenum, ileum and jejunum). In addition, the mRNA of CAT-2 was found in liver, lung, kidney, brain and muscle. Within the intestinal tract, CAT-2 mRNA was most abundant in the ileum and rarely expressed in the duodenum. In the duodenum, the levels of CAT-2 mRNA reached their peak on day 7 (p<0.05) while in the jejunum, levels were low on day 1 and 7 and increased rapidly after day 26 before peaking on days 30 and 60 (p<0.05). The levels then dramatically decreased by day 90 (p<0.05). In the ileum, levels achieved their maximum on day 30 and then decreased significantly on day 60 (p<0.05).
