We find the generating function for C(n, k, r), the number of compositions of n into k positive parts all of whose runs (contiguous blocks of constant parts) have lengths less than r, using recent generalizations of the method of Guibas and Odlyzko for finding the number of words that avoid a given list of subwords.

This paper concerns the problem of implementation of a multi-segment virtual memory with the number of segments variable in time on a memory consisting of one fixed size segment. The segments can differ in size but the size of each segment is invariable in time. For such a memory the following operations are defined: _ creating a segment of a given size, ~ removing an indicated segment, _ addre...

Large data installations normally archive relatively inactive data to a near-line tape library. The tape library performs reasonably well for sequential-access retrieval workloads. However, if the retrieval access slices across multiple data sets, or makes retrievals from scattered portions of a large data set, then the performance can suffer

<p>Thyroid gland (TG) metastasis by laryngeal cancer is uncommon. However, now a days following concept of ‘organ preservation’, so ipsilateral hemithyroidectomy not required in every case with total laryngectomy (TL) for cancer. Studies T3 and T4 having, anterior commissure involvement, transglottic growth or subglottic extension indicates thyroidectomy the majority cases. Hemithyroidect...
