This paper discusses the process of optimizing truss structure step by from 2D to 3D space using finite element analysis. step-by-step optimization is carried out simplify analysis structures simple more complex cases. Optimization aims obtain minimum cross-sectional area and weight for each member. The stages in this study are starting a 2-dimensional (2D) with several two five members 3-dimen...

OBJECTIVE Progressive muscular atrophy (PMA) is a clinical diagnosis characterised by progressive lower motor neuron (LMN) symptoms/signs with sporadic adult onset. It is unclear whether PMA is simply a clinical phenotype of amyotrophic lateral sclerosis (ALS) in which upper motor neuron (UMN) signs are undetectable. To elucidate the clinicopathological features of patients with clinically diag...

Many neurons in the rat anterodorsal thalamus (ADN) and postsubiculum (PoS) fire selectively when the rat points its head in a specific direction in the horizontal plane, independent of the animal's location and ongoing behavior. The lateral mammillary nuclei (LMN) are interconnected with both the ADN and PoS and, therefore, are in a pivotal position to influence ADN/PoS neurophysiology. To fur...

in this paper, we discuss the equivalent conditions of pretopological and topological $l$-fuzzy q-convergence structures and define $t_{0},~t_{1},~t_{2}$-separation axioms in $l$-fuzzy q-convergence space. {furthermore, $l$-ordered q-convergence structure is introduced and its relation with $l$-fuzzy q-convergence structure is studied in a categorical sense}.

One of the most demanding current mega engineering projects on Earth is to build a space elevator for various space applications. The current trend in new inflatable structure applications lends itself to study for the preliminary engineering design analysis of the space tower. Today, to access outer space, conventional chemical rockets are the only method in use. This method is extremely ineff...

The purpose of multi-tower crane motion planning is to find a collision-free construction process for multiple tower cranes operating in a construction site. This problem can be reduced to the path searching problem in highdimensional space and an important amount of research related to the path search algorithm has been published in various fields. In this paper, we analyzed the features of hi...

We consider the problem of classifying the orbits within a tower of fibrations with P-fibers that generalize the Monster Tower due to Montgomery and Zhitomirskii. The action on the tower is given by prolongations of diffeomorphism germs of 3-space. As a corollary we give the first steps towards the problem of classifying Goursat 2-flags of small length. In short, we classify the orbits within t...

the aim of this paper is to study the high order difference scheme for the solution of a fractional partial differential equation (pde) in the electroanalytical chemistry. the space fractional derivative is described in the riemann-liouville sense. in the proposed scheme we discretize the space derivative with a fourth-order compact scheme and use the grunwald- letnikov discretization of the ri...
