Replicant

Artist Statement This body of work explores technology throughout modern history into today, and how it affects society and the people within. There are many sides to technological innovation, and as time goes on it also changes our own priorities; even how we choose to either reject reality or intensify the effects of mass consumerism. Technology can also change the way we look at currency itself, surprise us with an unexpected reality or change what we view as beauty. Within this work I utilize drawing, printmaking, and collage to visualize our observed reality, the implications of the decisions we make, and how we interact with technology. I use saturated and appealing color palettes to draw the viewer into the content and questions that the work imposes

Determination of temperature distribution on windings of oil transformer based on the laws of heat transfer

Object of research: development of a technology for determining the temperature of the winding of a power oil transformer, in particular, the analysis of thermal processes in the winding of a power transformer during short-term overloads, taking into account the influence of the environment. Investigated problem: temperature distribution in the winding of a power oil transformer taking into account short-term load surges in the problem of assessing the residual life of the insulation of the transformer winding by temperature aging. The calculation of the temperature distribution in the winding was carried out using the passport data and characteristics of the power oil transformer, including the winding, transformer oil, load currents. Main scientific results: a mathematical model was calculated, with the help of which the results of temperature distribution in the transformer winding were obtained during short-term load surges or constant work with an increased load. According to the presented model, the analysis of the cooling time of the transformer winding after short-term overloads is carried out. Comparing the results obtained on the simulation model with the known results of experimental studies of the temperature distribution in the winding of a power transformer, the adequacy of the mathematical model is proved. It is shown that the use of the laws of heat transfer in a homogeneous plate to analyze the temperature distribution in the transformer winding is not wrong, but requires clarifications and simplifications. The area of practical use of the research results: enterprises of the machine-building industry and energy companies specializing in the production and operation of transformer equipment. Innovative technological product: simulation model of heat distribution in a transformer winding, which can take into account the load of the transformer, the effect of the environment on the insulation of the transformer windings. An innovative technological product: a method for diagnosing the duration of the non-failure operation of a transformer, which makes it possible to ensure trouble-free operation and save money for the repair of transformer equipment. Scope of application of the innovative technological product: design and development of diagnostic systems for windings of power oil transformer

Forecast of changes in the beach condition of the Yuzhne city under the influence natural factors

The study of the factors of degradation and the forecast of the state of recreational areas of the coast to prevent their negative changes is relevant. Purpose. Forecast of changes in the condition of the Yuzhne beach, provision of general proposals for its protection from degradation. Methods. Mathematical statistics, linear analysis and mathematical modeling, comparative analysis, cartographic and grapho-analytical studies. Results. The beach of Yuzhne is located on the coast of the Black Sea. Its length is approximately 700 m. The southern direction in the sector 180±22.5⁰ is dangerous for waves. The distance from the beach to the opposite shore (wave acceleration) is 540-610 km. The boundary between the shallow and deep water zones is at a distance of approximately 200 km with a depth of 75 m. With southerly winds, recurring once every 25 years, on the approach to the shallow water zone with a depth of 50-75 m, a developed disturbance with extreme wave parameters is formed, which, transforming in the shallow water zone, significantly affects the coast. A profile of relative dynamic equilibrium with a length of 1,200 m and a depth at this distance of 11.2 m is formed during the calculated disturbance. From the water cut, the boundary between the near-cut and surf zones is located at a distance of 220 m with a depth of 3.6 m. Regardless of the standing water level, the calculated storm destroys the original shore at the extreme parts of the beach. When the sea level is high, the disturbance moves the destroyed material with the beach material into the cut-off zone, while the water cut at the 0.0 m BS mark does not change its planned location. The amount of beach material on the upper part of the coastal slope may decrease significantly. At an average level of the sea, the washing away of destroyed and beach material is accompanied by the advance of the water cut toward the sea for a distance of up to 20 m, but at the same time, a decrease in beach material on the above-water part of the coastal slope is also observed. Conclusion. Without taking special protection measures, the beach of the Yuzhne city will degrade in the future. In areas of the beach, in order to prevent its erosion, it is necessary to erect a retaining wall with a backfilling layer. An option for an active method of protection can be the construction of permeable bunkers on the beach or an intermittent breakwater at a distance from the shore. Such protection will not impede the alongshore transport of sand. Dunes or waves will contribute to the accumulation of sand on the beach. At the same time, after strong storms from the southern direction, with high sea level, episodic additions of sand to the beach are necessar

No humans here: Exploration in the digital age

No Humans Here connects a lineage between landscape painters of the Hudson River School and Impressionists with 3D landscape renderings from artists of the early digital age at the turn of the millennium – work that conveyed an era of unbound creativity before dwindling as populated by more and more people over time. This transition diluted elements of exploration and curiosity through actions of curation, control, and exploitation - to the point that what once was, no longer remains. The initial magic, mystery and creativity of those early explorers and inhabitants in this digital age are now merely artifacts. As global exploration began to reach its limits by the mid 20th century, the advent of digital space opened new lands to cultivate and explore. Artists of the 90’s began using modeling programs, beginning with natural landscapes and architecture as a launchpad for creativity, akin to previous eras of landscape art – with particular comparisons to the Hudson River School. These early digital worlds were void of human inhabitants due to the practical nature of digital space itself – that humans do not exist directly within, rather we (currently) interact externally – or their presence is only alluded to because of technical limitations. Unlike early American landscape paintings, users of this new medium were unconstrained by romanticized realism or religious fervor, rather, they were unbound by the vastness of their own imaginations, and fantasy and science fiction literary influences of the 20th century such as J.R.R Tolkien (1892-1973) and William Gibson (b. 1948). Additionally, the use of light, color, and visual-distortion brushstrokes of Impressionist landscape painting parallels the pixelated, low-resolution imagery of the early digital age. As of this writing, humans do not physically exist within digital space but use it as a gateway for mental projection. Digital space exists outside of time itself – records of its early history still live on online, untouched and without decay, while also constantly evolving through the present. No Humans here pays homages to the creativity of early 90's digital landscapes through nostalgia and reimagining, while also questioning hope, loss, and entropy of our digital futures.Art & DesignCollege of Liberal Art

Mechanism of deformation of crystals during microidentification

The paper was aimed at the investigation of the mechanism of deformationof crystals with various bonds (ion, covalent, and combined) under the impact of concentrated load in a wide range of temperatures of deformation and correlation of microhardness with other parameters of plastic deformation in both homogeneous and heterogeneous fields of stress. As a result complex investigations of the peculiarities of plastic deformation under the impact of concentrated load in the rage of temperatures of 77-900 K were carried out on crystals with different bounds for the first time. The main rules of the microidentification were detected.

Solution of the contact problem on indentation of rectangular punch in an elastic roughnesses half-space in the presence of coulomb friction

The numerical solution of the static three-dimensional contact problem of the indentation of a rectangular stamp with a flat base in an elastic rough half-space in the presence of Coulomb friction and previously unknown adhesion and slip zones is obtained. Accounting for surface roughness in this problem is carried out based on the spherical model of microroughnesses by introducing the nonlinear terms describing surface microroughnesses crushing and shearing to the expression of relative displacement of the interacting bodies. The influence of the values of the friction coefficient and the parameters of the microscopic irregularities on the size and shape of the zone of adhesion and the distribution of the tangential contact stresses are analyzed. It is shown that the inclusion of surface microroughness shear forming roughness can lead to a substantial increase in the size of the zone of adhesion
