摘要：This paper presents a case study of reverse engineering closely-spaced free-form shapes. The raw point cloud data captured from a body scanner was processed to filter most noise and redundancy. They were used to generate meshes through triangulation of points. Upon removal of inconsistencies resulted from residual noise, the clean-up meshes were then used to reconstruct the free-form surfaces that represented a fabric layer and a human body surface. The solid produced between these two surfaces is the fabric-over-body model. It helped generate a FEA (finite-element analysis) mesh with quality checks, such as distortion and stretch, were performed for all the meshed tetrahedral elements. The purpose is to prepare a FEA-ready model for future CFD (computational fluid dynamics) analysis.

摘要：智能配电网除传统的树状拓扑结构外,还将出现环网、格状网等结构。建立具有这些特殊拓扑配电网的电力线信道模型,并进行信道特性影响因素的分析是在智能配电网中应用电力线载波通信技术的必要前提和重要依据。通过基于信息节点的建模方法建立格状网拓扑的信道模型,并仿真分析前后主干长度、格网主干长度、分支长度、分支负载等因素对格网拓扑下信道传输特性的影响规律,重点分析了这些影响因素对信号衰减的影响。通过实验验证了所得结果的正确性和有效性。所提出的分析方法和所得结论为设计智能配电网电力线载波通信的调制方法提供了必要的理论基础和技术手段。

摘要：Architectural design is leading us in the direction of structures with free and irregular forms. As a consequence of this the connection between the design’s intent and its fabrication represents a challenge when creating a support structure that is geometrically viable and which needs to possess certain aesthetic, fabricational, thermal and strength requirements. To ensure the contacts of the edges of the neighboring insulation panels along their thicknesses, the edges must be cut at different angles, which causes differences in the vertex heights and, furthermore, differences in the positions of the inner metal sheets of the insulation panels. The main goal of the presented research is the development of a post-optimization procedure, by which the minimum joint-height differences will be achieved for all the joints, taking into account all the free-form surfaces of the individual architectural design. To compensate for the residual height differences the use of spacers of different thicknesses is proposed. The paper considers the global minimization of the joint-height differences for a sample free-form architectural design that is meshed with a quad-dominant mesh.

摘要：随着半导体工艺的进步和SoC技术的不断完善,产生了借鉴并行计算和计算机网络设计思想的NoC概念。针对NoC的不规则2D mesh拓扑结构,提出了综合考虑功耗与面积的最优化映射模型,提高了运行效率。并且用模拟退火算法对3个多媒体播放器实例进行了模拟。实验结果表明,不规则mesh相对于规则mesh的拓扑结构,面积减小了75%,功耗减小了60%。同时与其它算法相比,平均耗时减小了90%。

摘要：Incisional hernias are a prevalent problem in abdominal surgery and occur in 11% of patients who undergo laparotomy. Primary suture clo-sure of incisional hernias results in a 31%-58% chance of recurrence. The addition of a pros-thetic mesh implant decreases recurrence rates to 8%-10%. Popularized in Europe by Rives and Stoppa, the sublay technique has proven to be very effective, with low recurrence rates (0%-23%) and minimal complications. The pur-pose of the study was to evaluate the experi-ence of a single surgeon at a large tertiary care center performing a modified Rives-Stoppa re-pair for abdominal incisional hernias. To do this, the records of all patients undergoing a modi-fied Rives-Stoppa incisional hernia repair be-tween January 2000 and August 2003 were ret-rospectively reviewed. Outpatient clinic notes, discharge summaries, operative reports, and laboratory data were reviewed for patient demographics, surgical data and postoperative complications. Univariate analysis was per-formed in order to identify predictors for recur-rence. During the study period, 83 patients un-derwent a modified Rives-Stoppa incisional hernia repair. Nineteen patients were excluded due to incomplete medical records. No patients required postoperative exploration for an in-tra-abdominal catastrophe. Twenty-five percent (n=16) of patients had a complication as a result of the hernia repair. Only two patients (3.1%) developed recurrent incisional hernias. History of diabetes (p=0.007) and benign prostatic hy-perplasia (p=0.000) were the only significant predictors for recurrence. The results presented here confirm that the modified Rives-Stoppa retromuscular repair is an effective method for the repair of incisional hernias. The complica-tion and recurrence rates compare favorably to results for currently popular alternative tech-niques.
