This paper presents a method for IFC-compliant design information modelling and sharing by use of the IFC technology and IFC property set (Pset) extension mechanism. The method comprises defining the nonstandard and project-specific design information in extensible and interoperable Psets, instantiating these Pset definitions with CAD object information and generating IFC-compliant product mode...

The increased functionality of EPC Class1 Gen2 (EPCGen2) is making this standard a de facto specification for inexpensive tags in the RFID industry. Recently three EPCGen2 compliant protocols that address security issues were proposed in the literature. In this paper we analyze these protocols and show that they are not secure and subject to replay/impersonation and statistical analysis attacks...

3 I owe this research to my wonderful husband, Donald, who has been my motivation and inspiration during these years. You suffered with me through the bad times and celebrated with me through the good times. My parents Joseph and Yvonne, and my brother, Nikolas, thank you for all of your support and love. You encouraged me to persevere when things got tough. Thank you. 4 ACKNOWLEDGMENTS I would...

We present an approach for operating unknown one-degree-of-freedom (DoF) mechanisms, using a compliant robot. The key aspect of our approach is that we make only little assumptions about the operated mechanism in terms of imposed kinematic constraints on the end-effector as well as dynamic properties, which can not always be neglected. The proposed system consists of: i) a constraint estimator ...

This report summarizes the evaluation of a controllable, instmmented compliant wrist. The design of th< wrist and the concept of a remote center of compliance (RCC) have been described in an earlier repoil (CMU-Rl-TR-82-9). The wrist is mounted on a large industrial robot used to load precisely machined parts int( jigs and fixtures on computer controlled machine tools. The robot and the machine...

This paper introduces conceptual design principles for a novel class of adaptive structures that provide both flow regulation and control. While of general applicability, these design principles, which revolve around the idea of using the instabilities and elastically nonlinear behaviour of post-buckled panels, are exemplified through a case study: the design of a shape-adaptive air inlet. The ...

Compliant assemblies are widely used in automobiles and airplanes etc. In order to simplify the complex assembly sequence planning problem of compliant assemblies involving dimensional variation caused by deformation, a two-step assembly sequence planning method is proposed in this paper. Meanwhile, an example of a wingbox assembly is used to explain the principle of the method. In the first st...

Reconfigurable Video Coding (RVC) aims to provide a framework allowing a dynamic development, implementation and adoption of standardized video coding solutions with features of higher flexibility and re-usability. RVC-CAL is a dataflow oriented language which is used for describing modules in the RVC framework. In this paper, an RVC-CAL description of an AVC intra prediction, module is present...

Abstract: In multi-objective optimization problems, the optimization target is to obtain a set of non-dominated solutions. Comparing solution sets is crucial in evaluating the performances of different optimization algorithms. The use of performance indicators is common in comparing those sets and, subsequently, optimization algorithms. A good solution set must be close to the Pareto-optimal fr...

| This paper presents a systematic approach for quantifying the quality of compliant grasps. Appropriate tangent and cotangent subspaces to the ob-ject's connguration space are studied, from which frame-invariant characteristic compliance parameters are de-ned. Physical and geometric interpretations are given to these parameters, and a practically meaningful method is proposed to make the param...
