This paper presents experimental results of subgroup discovery algorithms SD, CN2-SD and Apriori-SD implemented in the Orange data mining software. The experimental comparison shows that algorithms perform quite differently on data discretized in different ways. From the experiments, performed in the brain ischemia domain, it is impossible to conclude which discretization is the most adequate f...

We prove that the free Burnside Group B(3; 2) has order 27 and is isomorphic to ha; b j a3; b3(ab)3; (b 1a)3i. The technique of our proof is also used to show that ha; bja3; b3; a2(ba)nb2i is the semidirect product Cn2+n+1o C3.

The refractive index structure constant (Cn2) is a key parameter used in describing the influence of turbulence on laser transmissions atmosphere. Three different methods for estimating Cn2 were analyzed detail. A new method that uses combination these continuous profiling with both high temporal and spatial resolution proposed demonstrated. Under assumption Kolmogorov “2/3 law”, profile can be...

In the medical profession, recent technological advancements play an essential role in early detection and categorization of many diseases that cause mortality. The technique rising on daily basis for detecting illness magnetic resonance through pictures is inspection humans. Automatic (computerized) imaging has found you emergent region several diagnostic applications. Various death need to be...

The strength of optical turbulence, Cn2(z), 2-3 m above ground level, was measured as a function of distance along a 1.23-km path by the simultaneous capture of the scintillation from two infrared laser sources. The data collected differ in a number of important aspects from the normal vertical scintillation detection and ranging (SCIDAR) data in astronomy. The SCIDAR inversion method for the h...

Abstract Soft actuators are increasingly being required for a variety of application ranging from robotics to biomedicine. This work reports on the development printable materials soft actuator applications based ionic liquids (ILs) and fluorinated polymer, poly(vinylidene fluoride) (PVDF). ILs sharing same cation 1?butyl?3-methylimidazolium, [Bmim]+ different anions (tricyanomethanide, [C(CN3)...

The existence of a new two dimensional CN2 structure was predicted using ab-initio molecular dynamics (AIMD) and density-functional theory calculations. It consists tetragonal hexagonal rings with C-N N-N bonds arranged in buckling plane, isostructural to tetrahex-carbon allotrope. is thermodynamically kinetically stable suggested by its phonon spectrum AIMD. This nanosheet has high concentrati...
