Therapeutic effect of medical glue combined with the great omentum in severe tunica muscularis injury

REN Peitu, LU Baochun, RUAN Xinxian, CHEN Zhiliang, MA Yuliang, FU Hong

Frontiers of Medicine 2008, Volume 2, Issue 2,   Pages 143-146 doi: 10.1007/s11684-008-0027-9

Abstract: Twenty-seven patients with severe colon trauma treated in the Shaoxing People’s Hospital from 1995 to 2006 were retrospectively analyzed. The patients with severe tunica muscularis injury were treated by medical glue combined with the greater omentum during operations. The initial result was encouraging. All patients were cured with no anastomotic leakage or abscess. Therefore, reasonable use of medical glue combined with the greater omentum can not only improve the curative rate but also reduces postoperative complications for patients with colon injury.

Keywords： abscess     initial     muscularis     anastomotic     medical

Numerical investigation of circle defining curve for two-dimensional problem with general boundaries

Chung Nguyen VAN

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 1,   Pages 92-102 doi: 10.1007/s11709-018-0472-8

Abstract: The scaled boundary finite element method (SBFEM) is applied to the static analysis of two dimensional elasticity problem, boundary value problems domain with the domain completely described by a circular defining curve. The scaled boundary finite element equations is formulated within a general framework integrating the influence of the distributed body force, general boundary conditions, and bounded and unbounded domain. This paper investigates the possibility of using exact geometry to form the exact description of the circular defining curve and the standard finite element shape function to approximate the defining curve. Three linear elasticity problems are presented to verify the proposed method with the analytical solution. Numerical examples show the accuracy and efficiency of the proposed method, and the performance is found to be better than using standard linear element for the approximation defining curve on the scaled boundary method.

Establishing Profiles for Systems Engineering Standards: A Great Help for Companies to Manage Their Processes

Rui Xue,Claude Baron,Philippe Esteban,Qiang Zhang

Frontiers of Engineering Management 2014, Volume 1, Issue 3,   Pages 297-303 doi: 10.15302/J-FEM-2014036

Abstract: In this paper, we discuss how to establish profiles of system engineering standards for companies. To define an appropriate system engineering standard for a company, this paper presents a detailed comparison between the current releases of the main system engineering sta-ndards (ANSI/ EIA-632, ISO/IEC-15288 and IEEE-1220), and explains how to choose the most adapted one according to the company practices. When no standard completely corresponds, the paper illustrates how to elaborate a tailor-made standard on the basis of specific required characteristics of the company or of the project, following a multi-standard approach, leading to extend and adapt a sta-ndard by importing some elements from another.

Applying Rational Envelope curves for skinning purposes

Kinga Kruppa,kruppa.kinga@inf.unideb.hu

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 2,   Pages 141-286 doi: 10.1631/FITEE.1900377

Abstract: Special curves in the Minkowski space such as Minkowski Pythagorean hodograph curves play an important role in computer-aided geometric design, and their usages are thoroughly studied in recent years. Bizzarri et al. (2016) introduced the class of Rational (RE) curves, and an method for Hermite data was presented, where the resulting RE curve yielded a rational boundary for the represented domain. We now propose a new application area for RE curves: of a discrete set of input s. We show that if we do not choose the Hermite data correctly for , then the resulting RE curves are not suitable for . We introduce a novel approach so that the obtained curves touch each at previously defined points of contact. Thus, we overcome those problematic scenarios in which the location of touching points would not be appropriate for purposes. A significant advantage of our proposed method lies in the efficiency of trimming offsets of boundaries, which is highly beneficial in computer numerical control machining.

Strategic Study of CAE 2008, Volume 10, Issue 6,   Pages 56-62

Abstract:

This article reviews the developing tendency about the ocean exploration technology on the satellite remote sensing and its effect on the oceanic science. It looks back the developed status on the ocean satellite remote sensing technology, compares the domestic ocean remote sensing technology with overseas status simply and gives their differences. It presents the developing key technology in 2007—2020 years about our country's application technology on satellite ocean remote sensing. The first developing keystone about ocean remote sensing is to launch subsequence HY-1 satellite and HY-2 satellite. The satellite application will be stress on monitoring the ocean disaster such as red tide, overflow oil, water quality and sea ice etc. It is to table a proposal and policy about developing the application technology on the satellite remote sensing in our country.
