This paper presents the vector analysis used to develop an educational computer design tool which could enable prosthetists and mechanical designers to tailor the motion of low-cost, four-bar prosthetic knees to the sizes and needs of individual amputees. In designing a prosthetic knee joint, it is important to control the position of the lower leg in three angles of flexion and to control its center of rotation in the standing position. In 2010 [1] this problem was analyzed using vector methods, and an algorithm was written which produced curves displaying pivot locations which solve the problem exactly. Since then, a software tool called Speciknee has been developed by building on the core vector computational method and adding a user-friendly operator interface through which a designer could input individual patient needs, select pivot points along the set of curves where prosthetic joint pivots could be placed, and animate the mechanism.

The STEP File Analyzer is a software tool that generates a spreadsheet or a set of CSV (comma-separated value) files from a STEP (ISO 10303 –STandard for Exchange of Product model data) Part 21 file. STEP files are used to represent product and manufacturing information (PMI) and for data exchange and interoperability between Computer-Aided Design (CAD), Manufacturing (CAM), Analysis (CAE), and Inspection (CMM) software related to the smart manufacturing digital thread. STEP is also used for the long-term archiving and retrieval of product data. A spreadsheet simplifies inspecting information from the STEP file at an entity and attribute level. Typical STEP file viewers show a 3D visualization of the part or model represented by the STEP file. The viewers usually have a high-level hierarchical display of the information in the STEP file where the user can drill down to individual attributes of parts. However, there is no way to view all of the actual STEP entities and their attributes at once. The STEP File Analyzer provides this capability by creating a spreadsheet from the STEP file. The STEP File Analyzer also generates reports for PMI Representation, PMI Presentation, and Validation Properties based on Recommended Practices defined by the CAx Implementor Forum (CAx-IF) [5]. The objective of the CAx-IF is to advance CAx (mainly Computer-Aided Design and Engineering) software system STEP translator development and to ensure that user requirements for interoperability are satisfied.

The graphical user interface driven engineering software tool FlawPRO™ has been extensively used for subsea pipeline design and installation under high strain or fatigue intense applications. The methodology included in the program has evolved since its inception in 2002 through a series of JIPs involving major oil and gas operators and installation contractors. This paper summarises the fracture mechanics concepts incorporated in the methodology of the latest version of FlawPRO™ and the results of an extensive full scale flawed pipe testing programme that included over 45 reeling simulations and other fracture tests performed to validate the methodology. It is shown that the program’s crack growth predictions under large strain reeling are consistent with test data obtained from reeled pipes containing centreline flaws in over-matched welds, with the majority of the predicted results obtained using average material property data scattering around the mean 1:1 line consistent with uncertainties in the mechanical property values used in the validation. The results of an assessment of some of the reeling test data using the DNV ECA methodology (DNV-RP-F108) are also presented. It is concluded that the FlawPRO™ methodology is consistently more accurate in assessing the test data compared with the DNV methodology which may yield some non-conservative results. Both methodologies require suitable factors of safety or adjustments to either material and / or load inputs to maintain conservatism in applications to the pipeline projects.

Crash Tests

In general, crash test data have a comparatively large variation because of the complexity of the tests. However, only limited numbers of crash tests are usually conducted to assess the safety performance of a vehicle due to monetary and time limitation. Thus, it is necessary to control factors which cause the variation in the test data to have consistent crash test results and to correctly assess the safety performance of a vehicle under development. In this study, a MADYMO (MAthematical DYnamic MOdeling; an engineering software tool developed by TNO that allows users to design and optimize occupant safety systems) model was validated deterministically to result in similar head, chest, pelvis deceleration pulses and belt load pulses to those from tests, and it was also validated stochastically to result in similar mean and standard deviation values of HIC15 and 3 msec clip. By reducing the standard deviation of major factors which might cause the variation in the injury numbers, the reduced standard deviation of the injury numbers could be determined by conducting a stochastic analysis using the validated MADYMO model. The sensitivity of the standard deviation of the injury numbers to that of the major factors was calculated in order to determine the major factors which may cause the variation of the injury numbers the most. The sensitivity of the injury numbers implies that the variation in the air bag permeability and the critical load of the loadlimiter should be well controlled in order to reduce the variation in HIC15 and 3 msec clip, respectively.

Many scientists who implement computational science and engineering software have adopted the object-oriented (OO) Fortran paradigm. One of the challenges faced by OO Fortran developers is the inability to obtain high level software design descriptions of existing applications. Knowledge of the overall software design is not only valuable in the absence of documentation, it can also serve to assist developers with accomplishing different tasks during the software development process, especially maintenance and refactoring. The software engineering community commonly uses reverse engineering techniques to deal with this challenge. A number of reverse engineering-based tools have been proposed, but few of them can be applied to OO Fortran applications. In this paper, we propose a software tool to extract unified modeling language (UML) class diagrams from Fortran code. The UML class diagram facilitates the developers' ability to examine the entities and their relationships in the software system. The extracted diagrams enhance software maintenance and evolution. The experiments carried out to evaluate the proposed tool show its accuracy and a few of the limitations.
