eveloping software systems involves a series of activities where there are many opportunities to make errors. Such errors may occur at an early stage of the development process where user requirements are incorrectly or incompletely specified, and also in subsequent stages when design and programming faults are introduced. Thus, software development should always be accompanied by quality assur...

Inspection policies are essential for many types of systems for which the status (functioning or failed) can be determined only by actual inspection. Two types of inspection error may occur. A functioning system may be incorrectly assessed as having failed or a failed system may be incorrectly assessed as functioning. These errors are designated as Types I and II respectively, and their impact ...

this paper aims to investigate a new and intricate behavior of immediate follower during the lane change of leader vehicle. accordingly, the mentioned situation is a transient state in car following behavior during which the follower vehicle considerably deviates from conventional car following models for a limited time, which is a complex state including lateral and longitudinal movement simul...

Containers and cargos arriving at port-of-entry are inspected using sensors and devices to detect drugs, weapons, nuclear materials and other illegal items. Measurement errors associated with the inspection process may result in higher percentage of misclassification of containers. In this paper, we propose and formulate three inspection policies for containers at port-of-entry assuming the pre...

This paper describes an empirical study on typing errors made by children during a text copy exercise. The literature on text input errors is first examined, focussing on studies of errors that occur during keyboard typing. A study of errors made by children during typing is described and the results from this study are analysed using visual inspection and already published error categorisation...

This paper considers the role of comprehension during the preparation and defect detection phases of the software inspection process. Software inspection is generally accepted as a useful technique for finding errors in both documents and code. However, there is no general agreement on how defects are best detected and, in particular, how much understanding of the product is required and how th...

This memo describes the results of Shack-Hartmann wavefront sensor measurements of the 48” mirror at the Whipple Observatory, Mount Hopkins, AZ. The observations show significant errors in the figure of the primary mirror. Visual inspection of the data shows spots that are significantly shifted, distorted in shape, and some spots that are missing entirely from the images. Local slope errors on ...
