A ladle belt conveyor with increased traction ability is proposed at the request of Kostanay Minerals JSC. A geometric diagram of the conveyor route for cyclic-flow technology with the transportation of rock mass steeply falling conveyors in the contours of the quarry of the first stage of the Dzhetygara chrysotile deposit is given. The calculation of the geometric dimensions of individual sections of the conveyor is performed. The parameters of the transported material, the route and the bucket belt conveyor itself are determined.

Toulmin’S Model

The practice of formulating and justifying claims is a fundamental aspect of doing mathematics, and in geometry, students’ use of diagrams is integral to how they establish arguments. We applied Toulmin’s model to examine 23 geometry students’ arguments about figures included in a 1-point perspective drawing. We asked how students’ arguments drew upon their knowledge of 1-point perspective and their use of the diagram provided with the problem. Students warranted their claims based upon their knowledge of perspective, both in an artistic context as well as from experiences in everyday life. Students engaged in multiple apprehensions of the diagram, including using the given features, adding features, or measuring components, to justify claims about the figures. This study illustrates the importance of students’ prior knowledge of a context for formulating arguments, as well as how that prior knowledge is integrated with students’ use of a geometric diagram.

State Examination

The Mini-Mental State Examination was taken by 862 subjects from the general population, all born in 1931 and 55 to 57 years of age at the time of the study. These responses were analyzed in detail to obtain normative data for the test, and comparisons were made between the members of the group who had lifetime histories of psychiatric disorder and those who did not. Comprehensive comparisons were also made of the geometric diagram included in the test with the aim of finding non-pathological variations within correct geometric drawings. Apart from providing normative data, findings show a difference in the final score for the sexes, depending on whether Serial 7s are chosen or a word is spelled backwards. The men received a higher score on Serial 7s and the women a higher score on spelling a word backwards. A pretest choice is recommended in that the Serial 7s be selected for men, but omitted for women. Both gender differences and a psychiatric diagnosis correlate with the naming of two digits in a MMS subscore category.

Peircean Semiotics

The document illustrates some elements of reflection on Peirce's semiotics focused on reasoning through diagrams. The solution of a Euclidean geometry problem is taken as a reference in which mathematical diagrams are recognized as epistemological tools in the learning and teaching of geometry. This is how an interpreter, who systematically observes and experiments with a geometric diagram, generates different interpretants by means of abductive, inductive and deductive reasoning.

Geometric Diagram

The pupil who draws dashes through lines or angles in a geometric diagram to denote equality by hypothesis is taking advantage of an elementary logical symbolism. Ever since the days of Boole and Frege such symbolisms have become increasingly important in representing and furthering mathematical thought. Present day symbolic logic, which is an outgrowth of the methods of logical symbolism, has begun to revolutionize such diverse fields as the design of mathematical instruments, insurance analysis, brain physiology, and electrical network design. The study of symbolic logic at present occupies the full time research of at least two hundred creative mathematicians in our universities and industrial laboratories.

Probe Request

This paper presents a novel passive mobile device localization mode based on IEEE 802.11 Probe Request frames. In this approach, the listener can discover mobile devices by receiving the Probe Request frames and localize them on his walking path. The unique location of the mobile device is estimated on a geometric diagram and right-angled walking path. In model equations, site-related parameter, that is, path loss exponent, is eliminated to make the approach site-independent. To implement unique localization, the right-angled walking path is designed and the optimal location is estimated from the optional points. The performance of our method has been evaluated inside the room, outside the room, and in outdoor scenarios. Three kinds of walking paths, for example, horizontal, vertical, and slanted, are also tested.
