Ⅰ型中性点钳位(neutral point clamped, NPC)三电平变流器作为中大容量新能源发电系统的核心设备,其调制策略直接影响变流器的能量转换效率、谐波特性和运行控制特性等。鉴于Ⅰ型三电平变流器的传统空间矢量脉宽调制(space vector pulse width modulation, SVPWM)策略在实施过程中包含大量三角函数运算,基于三相静止坐标系进行调制算法的大小扇区判断和矢量作用时间计算等,并通过归纳整理,按照单调制波双载波的载波化思路,获得了适用于全扇区的三相统一的占空比函数。借助该占空比函数,变流器的数字控制器仅需通过简单的关系运算和数值计算,便可获得变流器功率管的控制信号,省去了大量三角函数计算,节约了硬件资源。此外,将SVPWM与正弦波脉宽调制(sinusoidal pulse width modulation, SPWM)+3次谐波注入调制算法进行对比,从调制波层面,揭示了这2种调制算法之间的内在差异。最后,通过仿真验证了该算法的有效性。

Circular and Faceted Monopile Installation Fatigue Damage

引用

Engineering（科研） 2016年第4期8卷 232-244页

作者： Giorge koulin Ian Sewell Brain A. Shaw Design Unit Newcastle University Newcastle upon Tyne UK

There are currently no models predicting localised stressing induced in monopole foundations resulting from pile driving installation. A scaled down test was conducted for both circular and faceted monopile, during which monopile stressing was measured. From the stress data gathered fatigue damage was estimated. Fatigue damage of the faceted geometry is significantly larger than that of the circular geometry. It is shown that in the worst case the fatigue damage incurred is still negligible compared to the full service life of the foundation. Suggestions for future developments are made, such developments can be helpful in providing greater understanding of the occasional cases where fatigue damage resulting from pile driving is not negligible and has perhaps resulted in failure.

Plasma von Willebrand factor level as a prognostic indicator of patients with metastatic colorectal carcinoma

引用

World Journal of Gastroenterology 2005年第14期11卷 2166-2170页

作者： Wei-ShuWang Jen-koulin Tzu-ChenLin Tzeon-JyeChiou Jin-HwangLiu Chueh-ChuanYen Po-MinChen DivisionofMedicalOncology DepartmentofMedicineTaipeiVeteransGeneralHospitalandNationalYang-MingUniversitySchoolofMedicineTaipei112TaiwanChina DivisionofColorectalSurgery DepartmentofSurgeryTaipeiVeteransGeneralHospitalandNationalYang-MingUniversitySchoolofMedicineTaipei112TaiwanChina

AIM:To evaluate the correlations of plasma von Willebrand factor (vWF) level with the distant metastasis and prognosis of patients with colorectal cancer. METHODS: A total of 86 patients with historically confirmed metastatic colorectal cancers receiving treatment at Taipei Veterans General Hospital were enrolled. All patients had measurable metastatic lesions and life expectancies of more than 3 mo. Plasma vWF levels were measured by immuno-turbidimetric assay and compared with results from 40 non-metastatic colorectal cancer patients and 22 healthy controls. Patients with metastatic colorectal cancer were divided into two groups according to serum vWF levels and the differences between these two groups were analyzed using X2 test. Data on age, gender, performance status, location of primary tumor, extent of metastasis, site of metastases, histological differentiation, serum CEA and plasma vWF levels were analyzed to determine association with survival. Survival curves were constructed by Kaplan-Meier product limit method and the data was analyzed using log-rank test on a microcomputer. Multivariate analysis using the Cox's proportional hazards regression model was then performed to determine the independent prognostic indicators among all of the possible variables. RESULTS: Colorectal cancer patients were identified as having significantly higher plasma vWF concentrations than healthy controls (P<0.05). Moreover, higher vWF plasma levels were associated with advanced tumor stage (P<0.05) and the presence of multiple metastases (P=0.014). Patients with lower vWF plasma levels (≤160%) survived significantly longer than those with a higher plasma vWF level (log-rank test, P= 0.0043). By multivariate analysis, plasma vWF levels (P<0.001), the extent of metastasis (P= 0.012), and the performance status (P=0.014) were identified as independent prognostic factors. CONCLUSION: Our data indicates that high plasma vWF concentrations correlate with advanced diseases and sign

Open Journal of Pathology 2016年第1期6卷 26-31页

作者： Tchin Darré Atchi Walla Tchilabalo Matchonna Kpatcha Abdoul-Samadou Aboubakari Nidain Maneh mikotakatola koulin.a Koffi Amégbor Gado Napo Koura Department of Pathology The University Teaching Hospital of Lomé Lomé Togo Department of Trauma and Orthopedic The University Teaching Hospital of Lomé Lomé Togo Department of Urology The University Teaching Hospital of Lomé Lomé Togo Department Obstetrics and Gynecology The University Teaching Hospital of Kara Kara Togo Department of Ophthalmology The University Teaching Hospital of Lomé Lomé Togo

Background: The elderly cancers are worldwide a major public health issue. Their exact incidence is unknown in Togo. The purpose of this study was to describe epidemiological and histological data of cancers in the elderly in Togo. Materials and Methods: This was a cross-sectional and descriptive study of cases of elderly cancers diagnosed at the laboratory of pathology of the university teaching hospital of Lomé from 1995 to 2014 (20 years). Cases of examination on samples of the elderly (biopsy, excision, surgical specimens) were collected from the data records of that laboratory. Results: Overall, 792/5200 cases of elderly cancer were collected representing 15.2% of all cancers diagnosed in the laboratory. The annual incidence was 39.6 cases. Patient age ranged from 65 to 103 years old, with a mean of 68.5 ± 4 years old. The sex ratio (M/F) was 1.3. At pathological level, the study material included pieces (n=290 cases;36.6%) and biopsies (n=502 cases;63.4%). Cancers located preferably in prostate in men (38%), and in women the most frequent locations were cervix (16.2%) and breast (15.8%). We noticed four histological groups: carcinomas (n = 706 cases;89.1%), sarcomas (n = 43 cases;5.5%), lymphoma (n = 34 cases;4.3%) and melanoma (n = 9 cases;1.1%). Carcinomas were dominated by adenocarcinomas (50.1%) and squamous cell carcinomas (33.8%);Kaposi’s sarcoma (32.6%) was the most common histological type in sarcomas. Conclusion: Our results showed that the elderly cancers were frequent in Togo, locating mostly in uterus cervix and breast in female, and prostate in men. This study could help to advocate the establishment of a cancer registry in Togo.
