In object oriented programming, it is sometimes necessary to copy objects and to compare them for equality or inequality. We discuss some of the issues involved in copying and comparing objects and we address the problem of generating appropriate copying and comparing operations automatically, a service that is not provided by most object oriented languages and environments. Automatic generatio...

C heating is a potentially serious problem on high-stakes tests, such as the Multistate Bar Exam (MBE), because it can result in under-qualified individuals receiving their Board’s certification to practice, thereby undermining the certification process. Because cheating on exams has such serious ramifications, it is important for test administrators to minimize cheating opportunities and detec...

In this work, control strategies for combining two potentially powerful buffer management techniques in object bases were devised and evaluated: (1) buffer pool segmentation with segment-specific replacement criteria, and (2) dual buffering consisting of copying objects from pages into object buffers. Two diiensions exist for exerting control on the buffer pool: (1) the copying time which deter...

The release of image processing techniques make image modification and fakery easier. Image fakery, here, is defined as a process to copy a region of source image and paste it onto the destination image, with some post processing methods applied, such as boundary smoothing, blurring, etc. to make it natural. The most important characteristic of image fakery is object copy and paste. In order to...

In recent years, loop tiling has become an increasingly popular technique for increasing cache eeectiveness. This is accomplished by transforming a loop nest so that the temporal and spatial locality can be better exploited for a given cache size. However, this optimization only targets the reduction of capacity misses. As recently demonstrated by several groups of researchers, connict misses c...

Vocal learning is relatively common in birds but less so in mammals. Sexual selection and individual or group recognition have been identified as major forces in its evolution. While important in the development of vocal displays, vocal learning also allows signal copying in social interactions. Such copying can function in addressing or labelling selected conspecifics. Most examples of address...
