CONCURRENT PRODUCTION ENGINEERING SYSTEM FOR BUFFER SIZE AND FLEXIBLE TRANSFER LINE LAYOUT DESIGN

Journal of Systems Science and Systems Engineering 2008年第2期17卷 187-203页

作者： hidehiko yamamoto Jaber ABU QUDEIRI M.Anouar JAMALI Intelligent Manufacturing Systems Laboratory Gifu UniversityJapan Department of Industrial Engineering University of Quebec at Trois-Rivers(UQTR)Canada

In this paper we propose a COncurrent Production Engineering System （COPES） for the flexible transfer line （FTL） layout design in a restricted area. COPES first determines the buffer size in front of the bay of each machine tool in the FTL and then initializes a computer aided design （CAD） system to draw the FTL in a restricted area. We develop a set of modules systems which have been integrated into a single framework, in accordance with the practice of concurrent engineering. Concurrent engineering involves the cooperation of these activities. It＇s expected that the developed COPES can improve the cooperation between production engineers＇ and the plant designer. This can be done by enabling the production engineers＇ to make better decision regarding FTL buffer size.

Journal of Mechanics Engineering and Automation 2012年第10期2卷 606-627页

作者： Takayoshi Yamada Manabu Yamada hidehiko yamamoto Department of Human and Information Systems Faculty of Engineering Gifu University Gifu 501-1193 Japan Department of Mechanical Engineering Faculty of Engineering Nagoya Institute of Technology Nagoya 466-8555 Japan

In this study, the static stability of the grasp of a single planar object is analyzed using the potential energy method. In previous papers, we considered cases in which individual fingers were replaced by a multidimensional translational spring model, in which each finger is constructed with prismatic joints. Human hands and the most developed mechanical hands are constructed with revolute joints. In this paper, the effects of fingertip rotation and a revolute joint spring model are investigated. A grasp stiffness matrix is analytically derived by considering not only frictional rolling contact but also frictionless sliding contact. The difl＇erence between the frictional stiffness matrix and the frictionless one is analytically obtained. The effect of local curvature at contact points is analytically derived. The grasp displacement directions affected by the change in curvature and the contact condition are also obtained. The derived stiffness matrix of the revolute joint model is compared with that of the prismatic joint model, and then the stiffness relation is clarified. The gravity effect of the object is also considered. The effectiveness of our method is demonstrated through numerical examples. The stability is evaluated by the eigenvalues of the grasp stiffness matrix, and the grasp displacement direction is obtained by the corresponding eigenvectors. The effect of joint angle is also discussed.

AIM:To investigate the predictors of success in stepdown of proton pump inhibitor and to assess the quality of life(QOL).METHODS:Patients who had heartburn twice a week or more were treated with 20 mg omeprazole(OPZ) once daily for 8 wk as an initial therapy(study 1).Patients whose heartburn decreased to once a week or less at the end of the initial therapy were enrolled in study 2 and treated with 10 mg OPZ as maintenance therapy for an additional 6 mo(study 2).QOL was in-vestigated using the gastrointestinal symptom rating scale(GSRS)before initial therapy,after both 4 and 8 wk of initial therapy,and at 1,2,3,and 6 mo after starting maintenance ***:In study 1,108 patients were *** characteristics were as follows;median age:63(range: 20-88)years,sex:46 women and 62 *** success rate of the initial therapy was 76%.In the patients with successful initial therapy,abdominal pain,indigestion and reflux GSRS scores were *** study 2,83 patients were *** of 83 patients completed the study 2 *** the per-protocol analysis,80%of 70 patients were successful for *** multivariate analysis of baseline demographic data and clinical information,no previous treatment for gastroesophageal reflux disease(GERD)[odds ratio (OR)0.255,95%CI:0.06-0.98]and a lower indigestion score in GSRS at the beginning of step-down therapy(OR 0.214,95%CI:0.06-0.73)were found to be the predictors of successful step-down *** improved GSRS scores by initial therapy were maintained through the step-down ***:OPZ was effective for most GERD ***,those who have had previous treatment for GERD and experience dyspepsia before stepdown require particular monitoring for relapse.

Double balloon enteroscopy to retrieve an accidentally swallowed dental reamer deep in the jejunum

引用

World Journal of Gastrointestinal Endoscopy 2011年第4期3卷 78-80页

作者： Shingo Kato Kazuhito Kani hidehiko Takabayashi Ryuichi yamamoto Koji Yakabi Department of Gastroenterology and Hepatology Saitama Medical CenterSaitama Medical UniversityKawagoe CitySaitama 350-8550Japan

Accidentally swallowed foreign objects are not uncommon but difficult to manage without complications. We describe the case of a 68 year old man who accidentally a swallowed sharp-pointed dental reamer that had reached deep in his jejunum. Double balloon enteroscopic retrieval was performed with polypectomy snare but the reamer was entangled in the wire loop of the snare and penetrated the jejunal wall. After releasing the reamer by pushing and pulling the snare for approximately 30 min, the reamer was retrieved with biopsy forceps. This is the first report of double balloon enteroscopic removal of a dental reamer. Furthermore, this is a novel case with regard to decision making in situations when sharp objects are swallowed.

目的找出可反映宫颈癌亚型不同组织结构的;F-脱氧葡萄糖（FDG）PET/CT纹理特征,并对宫颈癌中;F-FDG PET纹理特征的关联性进行视觉评估。方法纳入83例在治疗前行;FFDG PET/CT检查的宫颈癌患者,其中62例鳞状细胞癌（SCC）、21例非鳞状细胞癌（NSCC）。对PET/CT图像进行纹理分析,从中提取出18个PET放射组学特征,包括标准摄取值（SUV）、肿瘤代谢体积（MTV）和病灶糖酵解总量（TLG）等一级特征,二级以及高级结构特征分别为SUV直方图、归一化灰度共生矩阵（NGLCM）和局部灰度差分矩阵。使用Bonferroni校正P值0.002 8（0.05/18）来比较SCC和NSCC间这些特征的差异。用层次聚类的热图分析方法来评估PET特征之间的关联性。结果在18个PET特征中,相关性（NGLCM的二级纹理特征）是稳定的参数,并且是SCC和NSCC之间差异有统计学意义的唯一特征。SCC的相关性（0.70±0.07）显著高于NSCC（0.64±0.07,P=0.003 0）。其他PET特征在SCC和NSCC间无明显差异。与NSCC相比,SCC的高度相关性可能反映出癌细胞的结构完整性和更强的空间/线性关系。对PET特征进行热图分析,清晰显示出5个不同的群集,其中相关性与MTV、TLG属于一个群集,但相关性与他们的关联不强。相关性是宫颈癌相对独立的PET特征。结论;F-FDG PET纹理特征可能反映宫颈癌亚型间组织学结构差异。PET放射组学的方法揭示了PET特征间的关联性,并有助于发现单一特征或这些特征的组合,从而便于精确诊断、确定潜在的预后模型和有效的治疗策略。
