End-to-End Requirement Traceability through Contribution Structures and Requirements Traceability Matrices
2007Co-Authors: Aamrah Naqvi, Syed Irfan Hyder, Pakistan AirAbstract:Requirements traceability is the ability to follow the life of a Requirement i.e. from its origin, to its refinement and inclusion in the Requirement specification document, and from there to its subsequent deployment in coding, testing and validation. PreRequirement Traceability is concerned with Requirement’s life before its inclusion in the Requirement specification, while PostRequirement Traceability is concerned with the Requirement’s life after its inclusion in the Requirement specification. Pre-Requirement Traceability is typically not covered by existing tools because it is difficult to trace the origin of Requirements to the individuals who initiate, authenticate and document the user Requirements. This research indicates that the performance of these tools can be significantly improved by including Pre-Requirement Traceability in their traceability frameworks. Contribution structures specify relationships between the user Requirements and their initiators during pre-Requirement traceability. Traceability matrix is a structure often used by tools and techniques covering Post-Requirement Traceability. Thesis of this research is that the integration of contribution structures with the traceability matrix extEnds the traceability to both the pre and post-Requirement traceability phases and provides End-to-End coverage. This integration becomes possible when elements of a contribution structure are mapped to the elements of a Requirement traceability matrix. The entity relationship diagram can also be converted into relation database for its further utilization. Use of contribution structures in conjunction with Requirement traceability matrix helps in identifying relevant information about source of user Requirements, documenting in a reusable form to suit the needs of End users and enabling them to define their Requirements.

statistical delay budget partitioning in wireless mesh networks
Computer Communications, 2008Co-Authors: Najah Abuali, Hossam S HassaneinAbstract:Wireless Mesh Networks (WMNs) are currently attracting strong attention due to their great potential in supporting multimedia applications with real-time transport with last-mile Internet access. Multimedia End-to-End transmission requires Quality of Service (QoS) guarantees. Mapping End-to-End QoS Requirements into link QoS Requirements is an important step for providing QoS in WMNs. Despite the importance of this functionality, it is yet to be addressed in WMNs or, more generally, in multihop wireless networks. Such mappings, however, have resulted in several algorithms being proposed for connection-oriented wired networks. The algorithms proposed, nevertheless, are either near-optimal or heuristics, and provide solutions for only one End-to-End Requirement. In this paper, we propose a partitioning algorithm that is capable of partitioning multiple End-to-End QoS Requirements simultaneously. We define QoS as the pair of the required End-to-End delay and the violation probability of meeting the required End-to-End delay. Our approach is motivated by experiments decisively showing that the delay probability distribution can be accurately characterized by a gamma or logistic distribution, thus there is not a specific one distribution that can characterize the delay. This conclusion is used to formulate a mathematical linear program that optimally partitions the End-to-End delay and the violation probability into link delays and link violation probabilities without imposing any specific delay distribution. Extensive simulation verified the effectiveness of the algorithm compared to two representative QoS partitioning algorithms. The proposed algorithm outperforms the other algorithms for loose and stringent QoS Requirements, and over different path lengths.

A new approach to develop, characterise and model actuating textiles
'IOP Publishing', 2021Co-Authors: Kongahage Dharshika, Spinks, Geoffrey M., Richards, Christopher J., Shepherd, David J., Foroughi JavadAbstract:Smart materials are capable of recognising environmental stimuli, processing the information arising from the stimuli, and responding to it in an appropriate manner. It is well known that smart textiles provide some interesting possibilities in this regard. Consequently, smart textiles based on artificial muscles polymer actuators will provide a breakthrough to many areas including soft robotics, prosthetics, and healthcare for the benefit of humankind. Therefore, it is a worthy attempt to work on artificial muscle designs to aid them in applications. This paper presents the effect of fibre arrangement within a material structure for force and stroke generation. A method of fabrication, characterisation of actuating textiles was presented with experimental results. Most importantly, a modelling was carried out to develop equations to calculate the force and stroke of actuating textiles which has not been reported to date. A reasonable agreement was found between calculated and measured force/stroke curves of both woven and knitted textiles. The woven textile exhibited a force enhancement directly proportional to the number of actuators while retaining the same strain of the single actuator. Nonetheless, the force and strain of knitted textile were highly depEndent on the number of wales and courses per unit length. The fabricated knitted textile showed a lesser strain than the single actuator with a force amplification. However, the performance parameters of as fabricated knitted textiles were higher than the fabricated woven textile. Finally a practical applications, process for bulk manufacturing of silicone coated actuators was proposed to enable them in commercialised products and long length production. This study will enable developers to select the fibre architectures and suitable actuators to suit a particular End Requirement
