Research

My Contribution: 

• Wrote C++ and Matlab scripts allowing to extract the spectral characteristics of audio signals, change them using the time discretization shift method and wavelet transformation, and to regenerate the signals based on the updated spectral characteristics with small noises 

• Worked on the improvement of the restored signals quality and application of the work to information compression, background noise elimination and other areas

• Presented the project results at KSTA Student Conferences in 2010 and 2011 and was awarded 2nd and 1st places respectively

• Contributed to a conference publication as the first author and presented the projects results on the International Scientific - Practical Conference “Borders of Contemporary Science” in Krasnodar, 2013

Reflection: The project was my first research experience. I gained an understanding of audio signal spectral characteristic processing, acquired C++ and Matlab basic coding skills, and practiced technical writing and oral presentation.

My Contribution: 

• Defined the general construction characteristics of the given parallel shaft speed reducer units (the number of shafts and their arrangement, gear type, housing material, etc.)

• Performed gear measurements (tooth thickness, working depth, pitch diameter, etc.) 

• Recorded the consumer properties of the units (the gear ratio, torque, energy efficiency, weight, and size) 

• Extended the collected data using information published in the literature

• Explored the impact of the collected parameters on the units' consumer properties and determined the most favorable unit design characteristics

• Presented the work at KSTA Student Conference in 2011 and was awarded 1st place

Reflection: I learned about parallel shaft speed reducer units, got experience in data collection, integration, and analysis, and practiced critical thinking and oral presentation skills.

My Contribution: 

• Gathered published data on free-wheel inertial gear mechanisms' parameters (the number of plates, their width, thickness, material, etc.)

• Calculated bending stresses in the plates based on the collected parameters

• Identified parameters resulting in low bending stresses in the plates and thus providing their greatest durability

• Presented the work at KSTA Student Conference in 2011

Reflection: I learned about free-wheel inertial gear mechanisms, developed data collection and analysis skills, and practiced critical thinking and presenting results to an audience.

My Contribution: 

• Studied problems of electricity supply in megacities including the growing electricity demand, power outages, and the environmental impacts of electricity generation and transmission

• Studied solutions to different electricity supply issues including the growth of existing electric grids, the use of combined heat and power systems, and the modernization of electricity delivery

• Using publicly available data, designed and conducted case studies of electricity supply in a city where new transmission lines, substations, or electricity storage were added to the existing system; Explored advantages and disadvantages of the interventions 

• Presented the work at KSTA Student Conference in 2011 and was awarded 1st place

Reflection: I learned about electricity supply in megacities, acquired experimental skills, practiced data analysis and oral presentation.

Reflection: The work on the project positively influenced the development of my abstract thinking, imagination, and spatial ability.
