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.

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.

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.

자기 공명 영상을 이용한 안면비대칭환자의 측두하악관절 원반의 형태와 위치에 관한 연구

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.

Semisubmersible platforms with Steel Catenary Risers for Western Australia and Gulf of Mexico

Zou, Jun Techno-Press 2012 Ocean systems engineering Vol.2 No.2

Steel Catenary Risers (SCR) are the simplest and often the most economic solution compared to other riser types such as flexible pipe, riser towers, top tensioned risers, etc. The top of a SCR is connected to the host platform riser porch. The other end of the SCR connects to flowlines from subsea wells. The riser touchdown point (TDP), which is the location along the riser where contact with the sea floor first occurs, exhibits complex behaviors and often results in compression and fatigue related issues. Heave dynamic responses of semisubmersibles in extreme and operating sea states are crucial for feasibility of SCR application. Recent full field measurement results of a deep draft semisubmersible in Hurricane Gustav displayed the considerable discrepancies in heave responses characteristics between the measured and the simulated results. The adequacy and accuracy of the simulated results from recognized commercial software should be examined. This finding raised the awareness of shortcomings of current commercial software and potential risk in mega investment loss and environmental pollutions due to SCR failures. One main objective of this paper is to attempt to assess the importance and necessity of accounting for viscous effects during design and analysis by employing indicator of viscous parameter. Since viscous effects increase with nearly third power of significant wave height, thus newly increased metocean criteria per API in central Gulf of Mexico (GoM) and even more severe environmental conditions in Western Australia (WA) call for fundamental enhancements of the existing analysis tools to ensure reliable and robust design. Furthermore, another aim of this paper is to address the impacts of metocean criteria and design philosophy on semisubmersible hull sizing in WA and GoM.

Zou, J.,Park, J.,Yoon, H.,Mark Sammes, N.,Chung, J. Elsevier Sequoia 2013 Journal of alloys and compounds Vol.558 No.-

A systematic study of 10 transition metal ions (M=Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zn) doping in Ca<SUB>2.9</SUB>Bi<SUB>0.1</SUB>Co<SUB>4</SUB>O<SUB>9-δ</SUB> cathode for solid oxide fuel cells is performed by measuring their crystal structures, electrical conductivities and electrochemical performances. The presence of metal ion dopants in the Ca<SUB>2.9</SUB>Bi<SUB>0.1</SUB>Co<SUB>4</SUB>O<SUB>9-δ</SUB> matrix significantly influences its crystal structure and electrochemical performances. The electrochemical performances of metal ion-doped Ca<SUB>2.9</SUB>Bi<SUB>0.1</SUB>Co<SUB>4</SUB>O<SUB>9-δ</SUB> cathodes are quantified in terms of the electrical conductivity, impedance and power density of button cells. Doping with small amounts of ions for cobalt has negligible effect on the structure of powder samples as all of them form single-phase solid solutions with monoclinic misfit layered structure. However, the bar type samples of doping with Ti, Cr, Mn, Fe, Co, Ni, Cu and Zn keep the structure intact while those of doping with Sc and V slightly decompose after sintering. It is proposed that the metal dopants are located at different sites of double layered Ca<SUB>2.9</SUB>Bi<SUB>0.1</SUB>Co<SUB>4</SUB>O<SUB>9-δ</SUB> matrix due to their different ion radii, which mainly accounts for the difference of conductivity of doped samples. Among them, the Cu doped Ca<SUB>2.9</SUB>Bi<SUB>0.1</SUB>Co<SUB>4</SUB>O<SUB>9-δ</SUB> sample (Ca<SUB>2.9</SUB>Bi<SUB>0.1</SUB>Co<SUB>3.9</SUB>Cu<SUB>0.1</SUB>O<SUB>9-δ</SUB>) shows the highest electrical conductivity in the whole temperature range and has the lowest area specific resistance at 750 and 800<SUP>o</SUP>C. The Ca<SUB>2.9</SUB>Bi<SUB>0.1</SUB>Co<SUB>3.9</SUB>Cu<SUB>0.1</SUB>O<SUB>9-δ</SUB>|Ce<SUB>0.8</SUB>Sm<SUB>0.2</SUB>O<SUB>2+γ</SUB>|NiO+Ce<SUB>0.8</SUB>Sm<SUB>0.2</SUB>O<SUB>2+γ</SUB> button cell shows obvious improvement than Ca<SUB>2.9</SUB>Bi<SUB>0.1</SUB>Co<SUB>4</SUB>O<SUB>9-δ</SUB>|Ce<SUB>0.8</SUB>Sm<SUB>0.2</SUB>O<SUB>2+γ</SUB>|NiO+Ce<SUB>0.8</SUB>Sm<SUB>0.2</SUB>O<SUB>2+γ</SUB> button cell. The maximal power densities of the Ca<SUB>2.9</SUB>Bi<SUB>0.1</SUB>Co<SUB>3.9</SUB>Cu<SUB>0.1</SUB>O<SUB>9-δ</SUB> cathode-cell were 689, 465 and 331mWcm<SUP>-2</SUP> at 800, 750 and 700<SUP>o</SUP>C respectively.

Optimal Routing Strategy on Scale-free Networks with Heterogeneous Delivering Capacity

Zou Yamei,Li Zuoming 보안공학연구지원센터 2015 International Journal of Future Generation Communi Vol.8 No.1

We proposed the information traffic dynamics on scale-free networks considering the heterogeneous delivering capacity. In the previous researches, the delivering capacity is the same for all nodes in the system, which obviously contradicts the real observations. In this paper, a heuristic algorithm for the optimization of transport is proposed to enhance traffic efficiency in complex networks, where each node's capacity is set as ci = ki and ki is the degree of node i. Our algorithm balances traffic on a scale-free network by minimizing the maximum effective betweenness, which can avoid or reduce the overload in some busy nodes. The simulation result shows that the network capacity can reach a very high value, which is four times more than that of the efficient routing strategy. The distribution of traffic load is also studied and it is found that our optimal routing strategy can make a good balance between hub nodes and non-hub nodes, resulting in high network capacity.

Positive Association Between miR-499A>G and Hepatocellular Carcinoma Risk in a Chinese Population

Zou, Hong-Zhi,Zhao, Yan-Qiu Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.3

A case-control study of the association of miR-499A>G rs3746444 with risk of hepatocellular carcinoma (HCC)was conducted. Patients with HCC and healthy control subjects were recruited for genotyping of miR-499A>G using duplex polymerase-chain-reaction with confronting-two-pair primer(PCR-RFLP) analysis. The MiR-499 GG genotype was associated with a decreased risk of HCC as compared with the miR-499 AA genotype (adjusted OR=0.74, 95%CI=0.24-0.96). Similarly, the GG genotype showed a 0.45-fold decreased HCC risk in a recessive model. The MiR-499 G allele was significantly associated with decreased risk of HCC among patients infected with HBV in a dominant model (OR=0.09, 95%CI= 0.02-0.29). In conclusion, the MiR-499A>G rs3746444 polymorphism is associated with HCC risk in the Chinese population, and may be useful predictive marker for CAD susceptibility.
