Reading the Simultaneous Motion and Reality Bending Concepts through Doctor Strange

In order to exemplify the interaction between architecture and science fiction films, Doctor Strange (2016), one of today's cinema examples, was chosen because of that the special effects created in computer environment by transferring the dreams to the film have a surrealist effect on the film; of the fantastic spaces that arise with the deformation of real places become the main character of the film; of foreseeing a different future in terms of architecture. Within the scope of the study, the film was read through the changes of time and space of the concepts of “reality bending” and “simultaneous motion”. As a result of the readings on these concepts, the relationship of cinema with architecture has gained a different dimension, and it has been seen that this film can create a fantastic perspective and inspiration to the designers about the future deconstructivist buildings.

КАРКАСНА МОДЕЛЬ ОДНООСНОГО РОЗТЯГУВАННЯ КУЛІРНОГО ТРИКОТАЖУ ВЗДОВЖ ПЕТЕЛЬНИХ СТОВПЧИКІВ

The purpose of this study is to develop a frame model for stretching the weft-knits in the wale direction, suitable for further integration into the algorithm for building a three-dimensional knitwear model in a stretched state and modeling of interactive deformation dynamics. Methodology. Methods of theoretical analysis, basics of knitting theory, topological model of knitwear, methods of geometric modeling and parameterization were used in the research process. Findings. Modeling the physical and mechanical behavior of knitwear in a computer environment is one of the promising ways to increase the level of conformity of knitted products with the requirements of comfort and functionality. However, the complexity of the internal structure, the anisotropy of properties and the instability of the parameters of the loop structure determine the need to find non-trivial ways to solve the problem of mathematical description of the three-dimensional model of the thread, knitted in the knitwear, considering the stretching deformations. During the study, a frame model of a uniaxial stretching of knitwear in the wale direction was developed. The basis of the frame model is the idea of a knitted structure, represented as a logically organized set of elements, each of which is interlaces with other elements in accordance with the topology of knit. The frame of the jersey fragment is described as a set of bars and hinges. The hinges are located at the interlacing points of the loop heads and loop feet, and each rod in the model is an imaginary element representing a complex of force factors that prevent the change of distance between the hinges connected to the given rod. In the process of stretching, the geometrical characteristics of the elements change, while the logical connections remain unchanged. The wireframe model allows to define coordinates of interlacement points in the coordinate system of the sample, relative position of coordinate systems of each elementary fragment, which correspond to given loops, coordinates of characteristic points of a loop for transition to a three-dimensional model of a knitted structure. Scientific novelty. For the first time, a frame model of deformation of the knit, suitable for three-dimensional modeling of its structure, considering deformation of the thrust, was developed. Practical value. The developed model can be used as mathematical support of systems of automated designing of knits.

Object-Based Trace Model for Automatic Indicator Computation in the Human Learning Environments

This paper proposes a traces model in the form of an object or class model (in the UML sense) which allows the automatic calculation of indicators of various kinds and independently of the computer environment for human learning (CEHL). The model is based on the establishment of a trace-based system that encompasses all the logic of traces collecting and indicators calculation. It is im-plemented in the form of a trace database. It is an important contribution in the field of the exploitation of the traces of apprenticeship in a CEHL because it pro-vides a general formalism for modeling the traces and allowing the calculation of several indicators at the same time. Also, with the inclusion of calculated indica-tors as potential learning traces, our model provides a formalism for classifying the various indicators in the form of inheritance relationships, which promotes the reuse of indicators already calculated. Economically, the model can allow organi-zations with different learning platforms to invest only in one traces Management System. At the social level, it can allow a better sharing of trace databases be-tween the various research institutions in the field of CEHL.

Numerical and Experimental Vibration Analysis of a Steam Turbine Rotor Blade

Damage to the rotor blade of a steam turbine is a relatively common problem and is one of the leading causes of sudden and unplanned shutdowns of a steam turbine. Therefore, the high reliability of the rotor blades is very important for the safe and economical operation of the steam turbine. To ensure high reliability, it is necessary to perform a vibration analysis of the rotor blades experimentally and in a computer environment. In this paper, a modal analysis was performed on the twisted blade of the last stage of the turbine in the Ansys software. The results of the modal analysis of the stationary rotor blade were compared with the results obtained by the bump test, which confirmed the numerical model of the blade. A modal analysis of a rotating rotor blade was performed on the same numerical model, and Campbell diagrams were plotted to determine the critical speed

The Relationship Between Anaerobic Power and Arm Volume and Service Shot Speed in Volleyball Players

Aim: The aim of this study is to examine the relationship between upper extremity anaerobic power and arm volume with the correct service shooting rate of athletes interested in volleyball. A total of 13 male athletes playing elite level volleyball participated in the study. Method: Arm volumes were measured while the athlete was standing and legs were shoulder width apart. The distance between the acromion bone and the olecranon bone was measured with ± 1 mm accuracy at 10% intervals. Forearm volumes were measured while the athlete was standing and legs were shoulder-width apart. The distance between the olecranon bone and the ulnar styloid bone was measured with ± 1 mm accuracy at 10% intervals. To determine their anaerobic performance, Wingate anaerobic power and capacity test (AP) was performed on a pan arm ergometer, which was connected to a computer modified for this arm and operated with compatible software. The service speed (SS) of the athletes was used in Pocket Radar. Data evaluation was carried out using a statistical program in computer environment. "Shapiro-Wilk Test" was used for normal distribution of data. In statistical analysis, minimum and maximum values, arithmetic mean, standard deviation values were calculated. "Pearson" correlation analysis was used for the normally distributed data in the relationship of arm volume (AV) with anaerobic power. The data were evaluated according to the "0.05" significance level. Results: When the findings are examined, the AP and SS values of the athletes (r =, 843 **; p <, 001), RightAV values with SS (r = .857 **; p <, 000), LeftAV and SS values (r = .924 **; p <, 000) and significant relationship was found between Total AV and SS values (r =, 894 **; p <, 000). Conclusions: As a result, the findings of our study showed that men who do elite volleyball sports both have high upper extremity anaerobic power characteristics and have a high percentage of muscles around the arm, and play a decisive role in the correct service shooting speed.
