A prevalence of heavy-tailed, peaked and skewed uncertainty phenomena have been cited in literature, dealing with economic, physics, and engineering data. This fact has invigorated the search for continuous distributions of this nature. In this paper we shall generalize the two-sided framework presented in Kotz and van Dorp (2004) for the construction of families of distributions with bounded s...

The Power TAC is a competition-based simulation of an electricity market. The goal of the competition is to test retailer (broker) strategies in a competitive environment. Participants create broker agents that trade electricity. In this paper we describe our broker, which we created as a participant of the 2014 Power TAC competition. We describe the strategies for two main components of the ga...

In this paper we investigate how readability varies between texts originally written in English and texts translated into English. For quantification, we analyze several factors that are relevant in assessing readability – shallow, lexical and morpho-syntactic features – and we employ the widely used Flesch-Kincaid formula to measure the variation of the readability level between original Engli...

We show that the problem of representing every odd positive integer as the sum of a squarefree number and a power of 2, is strongly related to the problem of showing that p 2 divides 2 p?1 ? 1 for \few" primes p.

We say a number is flat if it can be written as a non-trivial power of 2 times an odd squarefree number. The power is the “exponent” and the number of odd primes the “length”. Let N be flat and 4-perfect with exponent a and length m. If a 6≡ 1 mod 12, then a is even. If a is even and 3 ∤ N then m is also even. If a ≡ 1 mod 12 then 3 | N and m is even. If N is flat and 3-perfect and 3 ∤ N , then...

We show how automorphisms can be used to reduce signiicantly the resources needed to enforce laws in p-groups. This increases the extent to which Burnside groups with prime-power exponent can be studied in detail. For example, we describe how to construct power-conjugate presentations for the restricted Burnside groups R(5; 4) and R(3; 5) which have orders 2 2728 and 5 2282 respectively. We als...

When two speech signals are mixed in a single channel the voiced parts of any of them remain mostly unaltered during the voicing interruptions of the other, i.e. pauses and voiceless consonants. The mixture is made of 3 types of multivoiced segments noted 0V (unvoiced), 1V (one voicing) and 2V (two voicings). A statistical study of readaloud texts reveals that total time spent in the 1V state i...

Abstract. In this paper, we construct two binary linear codes associated with multi-dimensional and m−multiple power Kloosterman sums (for any fixed m) over the finite field Fq. Here q is a power of two. The former codes are dual to a subcode of the binary hyper-Kloosterman code. Then we obtain two recursive formulas for the power moments of multi-dimensional Kloosterman sums and for the m-mult...

We address the problem of reconstructing a non-duplicated ancestor to a partially duplicated genome in a model where duplicated content is caused by several tandem duplications throughout its evolution and the only allowed rearrangement operations are DCJ. As a starting point, we consider a variant of the Genome Halving Problem, aiming at reconstructing a tandem duplicated genome instead of the...
