We show that any capacity or fuzzy measure ranging on a qualitative scale can be viewed both as the lower bound of a set of possibility measures, and the upper bound of a set of necessity measures. An algorithm is provided to compute the minimal set of possibility measures dominating a given capacity. This algorithm relies on the representation of the capacity by means of its qualitative Moebiu...

The reproductive performance of a dairy herd has a significant effect on the profitability of that herd. Common measures of reproductive performance are days to first service, days to conception, calving interval, services per conception, conception rate, estrus detection rate, and pregnancy rate. Most cow operations would benefit economically by reducing the number of operational days, decreas...

Still and multi-media images are subject to transformations for compression, steganographic embedding and digital watermarking. We propose new measures and techniques for detection and analysis of steganographic embedded content. We show that both statistical and pattern classification techniques using our proposed measures provide reasonable discrimination schemes for detecting embeddings of d...

introduction: endoscopy is an invasive procedure and finding noninvasive alternative tools in detection of probable upper gastrointestinal (gi) tract injuries following caustic ingestion is an area of interest. the present study aimed to evaluate the screening performance characteristics of thoraco-abdominal computed tomography (ct) scan in this regard. methods: this prospective cross sectional...

introduction: the potential benefit of ultrasonography for detection of thoracic bone fractures has been proven in various surveys but no comprehensive conclusion has been drawn yet; therefore, the present study aimed to conduct a thorough meta-analytic systematic review on this subject. methods: two reviewers independently carried out a comprehensive systematic search in medline, embase, isi w...

How to measure the performance of an edge detection method is an open problem. Many performance measures have been presented in the literature. However, there seems to be no agreement on the best option, and there exist no practical studies of the features of some of the most recent measures. In this work we make a comprehensive overview of the different proposals, followed by a practical compa...
