Simultaneous thermal analysis (STA) method has been applied to study decomposition reactions of AP under a flowing nitrogen atmosphere and static air. Results obtained indicate that a phase transformation occurs prior to the decomposition reaction. Decomposition takes place exothermally in two stages, first stage of decomposition could be suppressed by the controlled heating programme. Addi...

in 2005, a. abdollahi and a. rejali, studied the relations betweenparadoxical decomposition and configuration for semigroups. in thepresent paper, we introduce one other concept of amenability typeon semigroups and groups which includes amenability of semigroupsand inner-amenability of groups. we have extend the previous knownresults to semigroups and groups satisfying this concept.

This paper presents a hierarchical motion planner for humanoid robots navigating complex environments. We use a workspace decomposition that allows our planning algorithm to be separated into high-level, subgoal, and local algorithms. The workspace decomposition consists of a passage map, obstacle map, gradient map, and local map. We verify our approach using a virtual humanoid robot in a simul...

We prove a new ‘runner removal theorem’ for q-decomposition numbers of the level 1 Fock space of typeA (1) e−1 , generalising earlier theorems of James–Mathas and the author. By combining this with another theorem relating to the Mullineux map, we show that the problem of finding all q-decomposition numbers indexed by partitions of a given weight is a finite computation.

Plant genetic variation and herbivores can both influence ecosystem functioning by affecting the quantity and quality of leaf litter. Few studies have, however, investigated the effects of herbivore load on litter decomposition at plant genotype level. We reduced insect herbivory using an insecticide on one half of field-grown Betula Pendula saplings of 17 genotypes, representing random intrapo...

We describe a simulator-parallel method for parallelization of a large industrial Compositional Simulator. Our approach is based on domain-decomposition, with a coarse grid operator, generated by a Galerkin technique. The technique is highly object-oriented, which gives a high level of parallelization. Also inclusion of local mesh reenement can be done in a eecient and exible way. The code is r...

The classification of the lower levels of Lu I is mainly based on the pioneer work of Meggers and Scribner [1] and Klinkenberg [2 ] . In a recent investigation Verges and Wyart [3] observed 155 emission lines in the infrared region of 1 — 3.7/<m. By means of Fourier transform spectroscopy they measured the magnetic and electric hyperfine constants of the combining levels of 40 lines for the iso...

In 1982, Arjen Lenstra, Hendrik Lenstra Jr. and László Lovász introduced an efficiently computable notion of reduction of basis of a Euclidean lattice that is now commonly referred to as LLL-reduction. The precise definition involves the R-factor of the QR factorization of the basis matrix. In order to circumvent the use of rational/exact arithmetic with large bit-sizes, it is tempting to consi...

This paper presents a digital watermarking scheme based on a new application of DWT and SVD for color artworks protection. This scheme uses the major features of the two chrominance components where the watermark bits are embedded only into one chrominance component according to the color prevalence rate. In watermark embedding process, more modifications can be done upon the selected chrominan...
