We present a generalisation of the sifting procedure introduced originally by Sims for computation with finite permutation groups, and now used for many computational procedures for groups, such as membership testing and finding group orders. Our procedure is a Monte Carlo algorithm, and is presented and analysed in the context of black-box groups. It is based on a chain of subsets instead of a...

The rationale for clinical coding is to associate concepts with precise meanings to patient data. One of the most widely used coding systems is ICD-9-CM. Due to several limitations associated with this system, coding cannot adequately be performed without additional computational linguistic tools. In this paper, the development of a clinical thesaurus and an appropriate set-theoretic algorithmi...

The use of epoxy resins in metal structures for adhesive reasons is getting wider. Epoxy resins possess enhanced mechanical, chemical and physical properties, i.e. increased shear and compression strength, resistance in solvents, as well as at high temperatures. Tensile tests were carried out with standard aluminium tension specimens glued with epoxy resins. The thickness of the glue and the ac...

Double aortic aneurysm (DAA) falls under the category of multiple aortic aneurysms. Repair is generally done through staged surgery due to low invasiveness. In this approach, one aneurysm is cured per operation. Therefore, two operations are required for DAA. However, post-first-surgery rupture cases have been reported. Although the problems involved with managing staged surgery have been discu...

The estimation of a finite population distribution function is considered when there are missing data. Calibration adjustment used for dealing with nonresponse at the stage. Several procedures proposed and compared. A numerical study carried out to evaluate performances estimators. Computational problems implementation calibration estimators also considered.

context despite advancements in the science of surgery, minimizing bleeding from parenchymal tissue of the liver continues to be one of the challenges surgeons are facing to protect patients’ lives. however, the number of surgeries needing incisions in the liver tissue, e.g. metastatectomy, is constantly increasing. conclusions the excessive blood loss and the long time needed to control the bl...

Neuromedin B (NMB) (Minamino et al., 1983), a ten residue (GNLWATGHFM-NH2, Figure 1) neuropeptide, belongs to the ranatensin subfamily of bombesin-like peptides (Erspamer, 1980) which exhibits a wide range of biological responses in the central nervous system and gastrointestinal tract including thermoregulation (Marki et al., 1981), stimulation of the secretion of gastrointestinal hormones (Gh...

Acquiring and incorporating intraoperative data into image-guided surgical systems has been shown to increase the accuracy of these systems and the accuracy of image-guided surgical procedures. Even with the advent of powerful computers and parallel clusters, the ability to integrate highly resolved computer model information in the planning and execution of image-guided surgery is challenging....

A class of discrete time GI/D/k systems is considered for which the interarrival times have finite support and customers are served in first-in first-out FIFO order. The system is formulated as a single server queue with new general independent interarrival times and constant service duration by assuming cyclic assignment of customers to the identical servers. Then the queue length is set up as...

Ab initio quantum chemical calculations, G3B3, second-order Møller– Plesset (MP2), and the hybrid density functional method B3LYP were employed to compute the proton affinities of 24 heterocyclic amines. A range of basis sets are employed, starting from doublepolarization quality to triplequality basis set with augmented diffuse and polarization function. Experimental values were used to calibr...
