Abstract:

“Discovering the unexpected is more important than confirming the known [7]. In software development, the “unexpected” one relates to defects. These defects when unattended would cause failure to the product and risk to the users. The increasing dependency of society on software and the crucial consequences that a failure can cause requires the need to find out the defects at the origin itself. Based on the lessons learnt from the earlier set of projects, a defect framework highlighting the 5 Dimensions (Ds) of defect origin is proposed in this work. The defect framework is b

Abstract:

Line defects are ubiquitious features in interfaces, and have important structural and mechanistic role. Recently, a crystallographic theory of such defects has been presented which appears to offer a comprehensive framework for their classification. The object of the present paper is firstly to outline the characterisation and classification of defects according to this treatment. Secondly, we illustrate examples of defects in the distinctive classes observed using tern, and discuss the various imaging techniques which have been employed.In the absence of a rigorous treatment of line defects

Abstract:

In press working, to prevent defects in sheet products and establish the traceability of the causes of defects, we have developed defect detection dies incorporating several types of sensor, including load sensors, fiber laser sensors, ultrasonic sensors and optional sensors. Typical defects such as the rising of pierced scraps, burrs, spring-back/spring-go and wrinkling can be detected using the defect detection dies, i.e., the intelligent forming dies. The real-time defect inspection of all products will be possible. This system can be used to identify defective products on the basis of sens

Abstract:

Congenital heart disease is the most frequent birth defect and the leading cause of death for the fetus and in the first year of life. The wide phenotypic diversity of congenital heart defects requires expert diagnosis and sophisticated repair surgery. Although these defects have been described since the seventeenth century, it was only in 2005 that a consensus international nomenclature was adopted, followed by an international classification in 2017 to help provide better management of patients. Advances in genetic engineering, imaging, and omics analyses have uncovered mechanisms of heart f

Abstract:

Concrete defects have a significant impact on concrete constructions. These defects should be considered not only aesthetic defects but also structural defects. In this study, a novel Surface Defect Index (SDI) method was developed to quantify the defect volume according to liquids’ penetrating properties by applying ready-mixed plaster (RMP). The SDI refers to the volumetric proportion of all apparent and unapparent defects in a given area of concrete, and it is expressed as a percentage of the total volume affected by defects. The proposed SDI method was validated and tested under various co

Hot isostatic pressing (HIPping) technology is used for healing the casting defects for aerospace applications. Castings used for aerospace applications like turbo-pumps need to meet very stringent quality requirements. Complexity of the castings used in these applications, makes it difficult to meet the quality requirements in all the areas. Defects like gas holes, shrinkages, cavities etc. may occur in few locations and need to be repaired by welding or healed by HIPping. In the present study, we attempted to simulate the defect healing capability of HIP in a systematic manner. Artificial de

The development of new product with low cost and reliable quality is one of important means to improve customer satisfaction and increase manufactures’ profits. It is necessary to identify the key factors affecting product defects and control them early in the new product development (NPD) process with defect prediction methods, because defect prediction can effectively avoid or lower testing and unnecessary rework costs. The author proposes a new product defect prediction approach on the basis of Bayesian Network theory for decision-making in the NPD process. The proposed approach makes use o

This thesis investigated the refractive, accommodative and colour vision status of young people with Down's syndrome (DS). Seven separate studies were conducted. Participants were recruited from the Cardiff Down's Syndrome Vision Research Unit. Abnormal refractive development was reported from an early age, and continued through the first 15 years of life. The normal emmetropisation process was re-aligned to leave subjects with hypermetropic errors, with a wide variation in refractive error, at all ages. There was a specific development of oblique astigmatism with age, which may be associated

Pipeline defects such as cracks, dents and corrosion often require permanent pressure retaining repairs.

Abstract:

Composite materials installed on pipelines where damage generated by corrosion or erosion that begins as a wall-loss defect that can transition to a through-wall defect. Critically, the damage generated by the process tends to have a region of diffuse wall loss surrounding a through-wall penetration. Design qualification of repairs for through-wall defects are performed using simulated flaws manufactured by drilling through the pipe wall. This creates straight-sided flaws with significant remaining stiffness, very different from the diffuse, tapered flaws produced by erosion or corrosion. This

Abstract:

Guidance is needed for the pipeline industry's in-line inspection (ILI) technologies as current industry practices address mainly thin-wall pipe specifications as well as spool and defect design. Heavy-wall pipe is mostly found in subsea applications where the predominant threats are internal; however, external defects cannot be discounted. Nondestructive evaluation (NDE) sensing technologies for heavy-wall pipe often have very different specifications for examining external versus internal defects. The end uses for ILI technologies in the heavy-wall subsea applications often put a premium on

Abstract:

Full encirclement repair sleeves with fillet-welded ends are often used as permanent repairs on pipelines to reinforce and develop pressure retaining repairs on areas with defects, such as cracks, dents, or corrosion. In-service failures have occurred at pressure retaining sleeves as a result of defects associated with the sleeve welds, such as hydrogen-induced cracks, undercut at the fillet welds and inadequate weld size. Currently, there are no reliable methods to carry out a quantitative fitness for service assessment for a sleeve fillet weld with a weld fault because: - The stresses at the

Full text

Abstract:

This project extends the investigation of the remaining strength of blunt and sharp flaws in pipe to develop a new, simple equation, known as PCORRC, for predicting the remaining strength of corrosion defects in moderate- to high-toughness steels that fail by the mechanism of plastic collapse. This report summarizes the development of this criterion, which began with the enhancement of a special-purpose, analytical, finite-element-based software model (PCORR) for analyzing complex loadings on corrosion and other blunt defects. The analytical tool was then used to compare the influence of diffe
