architecting to Ensure Requirement relevance keynote twinpeaks workshop
Proceedings of the Fifth International Workshop on Twin Peaks of Requirements and Architecture, 2015Co-Authors: Jan BoschAbstract:Research has shown that up to two thirds of features in software systems are hardly ever used or not even used at all. This represents a colossal waste of R&D resources and occurs across the industry. On the other hand, product management and many others work hard at interacting with customers, building business cases and prioritizing Requirements. A fundamentally different approach to deciding what to build is required: Requirements should be treated as hypothesis throughout the development process and constant feedback from users and systems in the field should be collected to dynamically reprioritize and change Requirements. This requires architectural support beyond the current state of practice as continuous deployment, split testing and data collection need to be an integral part of the architecture. In this paper, we present a brief overview of our research and industry collaboration to address this challenge.

On the use of model transformation for Requirements trace models generation
2017 International Conference on Wireless Technologies Embedded and Intelligent Systems (WITS), 2017Co-Authors: Saida Haidrar, Adil Anwar, Ounsa RoudiesAbstract:Requirements traceability is handled in order to help stakeholders understanding existing dependencies between Requirements and development artifacts. In this paper, we aim at taking advantage from system engineering and model-driven engineering field in order to automatically generate trace links from SYSML models. Our approach establishes a transformation of Requirement diagrams and design diagrams into a trace model. The input SYSML model is compliant with the SYSML4TRACEABILITY profile that helps in capturing all traceability data before performing the transformation. The generated trace model is compliant with a trace meta-model and depicts various links between Requirements and design artifacts so as to Ensure Requirement traceability at different levels of granularity. We experiment this approach by extracting Requirements traces relevant to the anti-lock braking system.

Fast image processing on chain board of inverted tooth chain
3rd International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, 2007Co-Authors: Qing-min LiuAbstract:Discussed ordinary image processing technology of inverted tooth chain board, including noise reduction, image segmentation, edge detection and contour extraction etc.. Put forward a new kind of sub-pixel arithmetic for edge orientation of circle. The arithmetic first did edge detection to image by Canny arithmetic, so as to enhance primary orientation precision of edge, then calculated gradient direction, and then interpolated gradient image (image that was detected by Sobel arithmetic) along gradient direction, last obtained sub-pixel orientation of edge. Performed two kinds of least-square fitting methods for line edge to getting its sub-pixel orientation, from analysis and experiments, the orientation error of improved least-square linear fitting method was one quarter of ordinary least-square linear fitting error under small difference of orientation time. The sub-pixel orientation of circle made resolution of CCD increase 42 tines, which enhanced greatly orientation precision of image edge. For the need of quick on-line inspection next step, integrated the whole environment containing image preprocess, Hough conversion of line, setting orientation & direction of image, sub-pixel orientation of line and circle, output of calculation result. The whole quick processing course performed without operator, processing tine of single part is less than 0.3 second. The sub-pixel orientation method this paper posed fits precision orientation of image, and integration calculation method Ensure Requirement of quick inspection, and lays the foundations for on-line precision visual measurement of image.
