As already mentioned, the key distribution can be made simple and effective with smart cards which also contain the DES algorithm. The cards are customised by the operator and sent to each individual subscriber. The key stored in the card is uniquely related to the subscribers logical directory number, which again is uniquely related to the physical line. A smart card can thus only be used by t...

New spectral methods for ratio cut partitioning and clustering. A general purpose multi-way partitioning, Proc. We introduced a new natural metric, Via-Count, to better estimate inter-partition delays for evaluating partitioning solutions. We presented K-VIA-FM, an algorithm that iteratively improve solutions for the new metric. We compared the performance of K-VIA-FM with other algorithms, bot...

A high-throughput computing policy attempts to efficiently utilize all of the resources in a cluster to generate faster overall execution. It is acceptable for jobs running on a workstation serving remote pages to execute more slowly, if other jobs benefit by achieving faster execution times through the use of network RAM, as long as throughput is maximized. Further work must be done to fully u...

The concurrency is classified into two types: structured concurrency and nonstructured concurrency. After showing that the nonstructured concurrency cannot be represented by the conventional notations in the Petri net language, a method to represent such concurrency by the language is proposed. The proposed method allows us to utilize the existing approaches for analyzing properties of a nonstr...

objective: to identify the proportion and some selected characteristics of juvenile diabetics attending birdem hospital. materials and methods: this was a cross sectional study. the study was conducted in the birdem hospital. all diabetic young aged up to 18 years who visit birdem hospital were included in study population. the sample size was 240. results: it was observed that among the respon...
