Smoke Test Planning using Answer Set Programming

Smoke testing is an important method to increase stability and reliability of hardware- gramming, Testing depending systems. Due to concurrent access to the same physical resource and the impracticality of the use of virtualization, smoke testing requires some form of planning. In this paper, we propose to decompose test cases in terms of atomic actions consisting of preconditions and effects. We present a solution based on answer set programming with multi-shot solving that automatically generates short parallel test plans. Experiments suggest that the approach is feasible for non-inherently sequential test cases and scales up to thousands of test cases

Cost modelling and concurrent engineering for testable design

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.As integrated circuits and printed circuit boards increase in complexity, testing becomes a major cost factor of the design and production of the complex devices. Testability has to be considered during the design of complex electronic systems, and automatic test systems have to be used in order to facilitate the test. This fact is now widely accepted in industry. Both design for testability and the usage of automatic test systems aim at reducing the cost of production testing or, sometimes, making it possible at all. Many design for testability methods and test systems are available which can be configured into a production test strategy, in order to achieve high quality of the final product. The designer has to select from the various options for creating a test strategy, by maximising the quality and minimising the total cost for the electronic system. This thesis presents a methodology for test strategy generation which is based on consideration of the economics during the life cycle of the electronic system. This methodology is a concurrent engineering approach which takes into account all effects of a test strategy on the electronic system during its life cycle by evaluating its related cost. This objective methodology is used in an original test strategy planning advisory system, which allows for test strategy planning for VLSI circuits as well as for digital electronic systems. The cost models which are used for evaluating the economics of test strategies are described in detail and the test strategy planning system is presented. A methodology for making decisions which are based on estimated costing data is presented. Results of using the cost models and the test strategy planning system for evaluating the economics of test strategies for selected industrial designs are presented

Feasibility and Efficacy of Definitive Radiotherapy with 66 Gy and Concurrent Carboplatin-Paclitaxel Chemotherapy for Stage III Non-Small Cell Lung Cancer.

Purpose/Objectives : This study was conducted to assess the feasibility and efficacy of definitive radiotherapy (RT) with a total dose of 66 Gy and concurrent carboplatin-paclitaxel chemotherapy for patients (pts) with stage Ⅲ non-small celllung cancer. Materials/Methods : Between April 2007 and December 2013，99 pts with non-small cell lung cancer were treated using RT with concurrent carboplatin-paclitaxel chemotherapy in our hospital. Sixty-eight of them received RT with a total dose of 66 Gy. We analyzed 46 Stage Ⅲ pts who had been treated with RT using three-dimensional radiotherapy treatment planning. The prophylactic mediastinal lymph nodes were included in the clinical target volume for RT. The survival rate after the start of RT was estimated using the Kaplan-Meier method. We estimated the cumulative local failure and distant metastasis rates with the Fine-Gray method. Adverse events were evaluated according to the CTCAE (v.4.0). Results : The median age of the pts was 70.9 (52.8-78.7) years old (y.o.). The performance status (PS) of each pt was fairly good (ECOG PS 0: 25, PS 1: 20, PS 3:1), and their clinical stages (UICC 7th) were twenty-nine Ⅲ A and seventeen Ⅲ B. Diagnoses were pathologically confirmed in 32 pts. The median follow-up period was 35.7 (2.0-82.2) months among all pts, and 55.9 (40.1-82.2) months among survivors. The 3- and 5-year Kaplan-Meier overall survival rates were 52.2 and 34.0%，respectively, and the median survival time was 36.6 months. The 3- and 5-year Kaplan-Meier progression-free survival rates were 29.1 and 21.9%，respectively, and the median progression-free survival time was 9.9 months. The 5-year local failure rate was 37.6%, and the 5-year distant metastasis rate was 49.7%. Sixteen (34.8%) pts required steroid administration because of radiation pneumonitis (CTCAE Grade 2 or higher) and two of them died (Grade 5). No other severe non-hematologic toxicity (Grade 3 or higher) was observed. Conclusion : These results suggest that definitive RT with a total dose of 66 Gy and concurrent carboplatin-paclitaxel chemotherapy is feasible and may be promising for pts with Stage Ⅲ non-small cell lung cancer

Principles for aerospace manufacturing engineering in integrated new product introduction

This article investigates the value-adding practices of Manufacturing Engineering for integrated New Product Introduction. A model representing how current practices align to support lean integration in Manufacturing Engineering has been defined. The results are used to identify a novel set of guiding principles for integrated Manufacturing Engineering.

The research contribution is an illustration of aerospace Manufacturing Engineering practices for New Product Introduction. The conclusions will be used to indicate new priorities for New Product Introduction and the cross-functional interactions to support flawless and innovative New Product Introduction. The final principles have been validated through a series of consultations with experts in the sponsoring company to ensure that correct and relevant content has been defined

Modelling iteration in engineering design

This paper examines design iteration and its modelling in the simulation of New Product Development (NPD) processes. A framework comprising six perspectives of iteration is proposed and it is argued that the importance of each perspective depends upon domain-specific factors. Key challenges of modelling iteration in process simulation frameworks such as the Design Structure Matrix are discussed, and we argue that no single model or framework can fully capture the iterative dynamics of an NPD process. To conclude, we propose that consideration of iteration and its representation could help identify the most appropriate modelling framework for a given process and modelling objective, thereby improving the fidelity of design process simulation models and increasing their utility

Working Memory in Writing: Empirical Evidence From the Dual-Task Technique

The dual-task paradigm recently played a major role in understanding the role of working memory in writing. By reviewing recent findings in this field of research, this article highlights how the use of the dual-task technique allowed studying processing and short-term storage functions of working memory involved in writing. With respect to processing functions of working memory (namely, attentional and executive functions), studies investigated resources allocation, step-by-step management and parallel coordination of the writing processes. With respect to short-term storage in working memory, experiments mainly attempted to test Kellogg's (1996) proposals on the relationship between the writing processes and the slave systems of working memory. It is concluded that the dual-task technique revealed fruitful in understanding the relationship between writing and working memory

SCRIPTKELL : a tool for measuring cognitive effort and time processing in writing and other complex cognitive activities

We present SCRIPTKELL, a computer-assisted experimental tool that makes it possible to measure the time and cognitive effort allocated to the subprocesses of writing and other cognitive activities, SCRIPTKELL was designed to easily use and modulate Kellogg's (1986) triple-task procedure,.which consists of a combination of three tasks: a writing task (or another task), a reaction time task (auditory signal detection), and a directed retrospection task (after each signal detection during writing). We demonstrate how this tool can be used to address several novel empirical and theoretical issues. In sum, SCRIPTKELL should facilitate the flexible realization of experimental designs and the investigation of critical issues concerning the functional characteristics of complex cognitive activities
