The aim of this paper is to compute the rational character tables of the dicyclic group $T_{4n}$, the groups of order $pq$ and $pqr$. Some general properties of rational character tables are also considered into account.The aim of this paper is to compute the rational character tables of the dicyclic group $T_{4n}$, the groups of order $pq$ and $pqr$.

Hash tables are an essential data-structure for numerous networking applications (e.g., connection tracking, rewalls, network address translators). Among these, cuckoo hash tables provide excellent performance by allowing lookups to be processed with very few memory accesses (2 to 3 per lookup). Yet, for large tables, cuckoo hash tables remain memory bound and each memory access impacts perform...

The display of the data by means of contingency tables is used in different approaches to statistical inference, for example, to broach the test of homogeneity of independent multinomial distributions. We develop a Bayesian procedure to test simple null hypotheses versus bilateral alternatives in contingency tables. Given independent samples of two binomial distributions and taking a mixed prio...

"Sixty-five has long been thought of as the point of entry into ¿old age'. We propose a number of life table criteria for answering the following questions: If 65 was considered appropriate four decades ago, what is the corresponding age today? If 65 was (implicitly) a male-oriented definition four decades ago, as we believe it was, what would have been the appropriate definition for women at t...

In the paper the n−ary k−valued functions (k > 2) on a finite set of k elements with essential arity gap equal to p, p ≤ k are investigated. We give a formula (term-presentation of the functions which have given essential arity gap. This representation is based on the operation tables of the functions in their SC-forms as sums of conjunctions. The combinatorial problem how many there are k−valu...

The current economic climate makes it increasingly likely that the role of nurses in the operating theatre will be scrutinised once again. This article reports on how theatre nurses view their work, making some recommendations to try to improve the perception of theatre nursing outside operating departments.
