This paper presents a new method of analyzing the orientation angle rotatability of a planar serial n-link manipulator by examining the rotatability of its virtual equivalent *** orientation boundary region decomposition is proposed based on the polynomial discriminant derived from a serial three-link *** angle workspace indicates a set of angle ranges by which the end-effector can reach with certain orientation for every point in the reachable position *** introducing a virtual equivalent mechanism,the open-chain kinematic problem is converted into a close-chain mechanism,and the Grashof-type condition is used to examine the rotatability of the end-effector *** reachable position workspace can be divided into several Grashof intervals and non-Grashof intervals based on the extreme positions and singular configurations of a *** derived equations in this paper can be used to calculate the variation rule of the orientation angle workspace of any given planar serial n-link manipulator on the basis of its link *** orientation angle rotatability of a seven-link serial manipulator is solved by the proposed method and graphical representations of the orientation angle workspaces are mapped onto a three-dimensional coordinate *** theoretical approach has practical significance for the design of a highly dexterous serial n-link manipulator with proposed link relations.

Low-degree-of-freedom (Low-DOF) parallel manipulators (PMs) have drawn extensive interests, particularly in type synthesis in which two main formal approaches were established by using the reciprocal screw system theory and Lie group theory. This paper aims at numeration and type synthesis of orthogonal translational parallel manipulators (OTPMs) by resorting to an integration of the group- based method and graphical representation of the topology. For this purpose, the concept of Cartesian DOF-characteristic matrix, orig- inated from displacement subgroup and displacement submanifold, is proposed. A new approach based on the combination of the atlas of Cartesian DOF-characteristic matrix and the displacement group-theoretic method is addressed for both exhaustive classi cation and type synthesis of OTPMs. The proposed approach is prone to construct an orthogonal structure and is easy to realize the complete clas- si cation and exhaustive enumeration of this class of low-DOF PMs.

Early resection of hepatocellular carcinoma is a key measure to prolong the survival of patients. This study was designed to summarize our experience in surgical resection of small hepatocellular carcinoma (HCC), and to analyze the factors influencing the postoperative survival of patients. METHODS:The clinicopathologic data of 105 patients with small HCC after resection from 1986 through 2003 were analyzed ; the patients had been followed up for more than half a year (median 33 months). Nine clinicopathologic factors, preoperative α-fetoprotein (AFP) level, liver cirrhosis, Child-Pugh score, tumor size (>2cm vs.≤2 cm) and number (single vs. multiple), capsule formation, portal vein tumor thrombi (PVTT), Edmondson tumor grade and surgical method, were analyzed by the log-rank test and the Cox proportional harzards model analysis. RESULTS:The cumulative 1-,3- and 5-year survival rates after the operation were 86.5%, 70.3% and 55.2%, respectively, and the 1-, 3- and 5-year disease-free survival rates were 78%, 58. 9% and 45. 6%, respectively. One patient died from esophagogastric varices hemorrhage in 2 weeks after reoperation. Thirty-six patients had intrahepatic recurrence or metastasis postoperatively and 34 patients died. The Kaplan-Meier method and the Cox proportional harzards model analysis indicated that poor Child-Pugh score, tumor more than 2 cm in diameter, PVTT and multiple lesions (including satellitic lesions) were adverse factors affecting postoperative survival. The Cox proportional harzards model analysis indicated that tumor size, PVTT and multiple lesions were the factors influencing postoperative disease-free survival. CONCLUSIONS:Limited hepatectomy with a margin more than 1 cm is an appropriate surgical approach. Adverse preoperative Child-Pugh score and postoperative intrahepatic recurrences are the main factors leading to the death of patients with small HCC.
