The foot is constituted from a series of small bones making a segmented structure with multiple joints, likened to a dome, in contact with the ground in three points: posteriorly the calcanear tuberosity; anteriorly and medially the head of 1st metatarsum, and anteriorly and laterally the head of 5th metatarsum. In fact, each foot presents a semi-arch whose base is represented by the lateral bo...

The two-dimensional (2D) Self-Organizing Map (SOM) has a well-known "border effect". Several spherical SOMs which use lattices of the tessellated icosahedron have been proposed to solve this problem. However, existing data structures for such SOMs are either not space efficient or are time consuming when searching the neighborhood. We introduce a 2D rectangular grid data structure to store the ...

For developing innovative construction techniques, extensive research has been carried out on the behavior characteristics for shaping formation of space structures by means of cable-tensioning method. This paper discusses the shaping formation of space structures by means of post-tensioning of the cable in bottom chords. It is a fast and economical construction method used in many types of spa...

Abstract: Modal analysis is a powerful technique for understanding the behavior and performance of structures. Modal analysis can be conducted via artificial excitation, e.g. shaker or instrument hammer excitation. Input force and output responses are measured. That is normally referred to as experimental modal analysis (EMA). EMA consists of three steps: data acquisition, system identificatio...

Problem statement. Today, the world's leading researchers are engaged in investigating possibilities of building bases and settlements on surface Moon. To ensure protection crew for long-duration missions, development residential modules is required. An effective solution construction Moon use local soil (regolith) production concrete reinforcement. For today, there already data physical mechan...
