Main Stages Of Automated System Of Processes For Determining And Ensuring Functional And Parametric Compatibility Of Production And Technological Systems, Sarvar Botir Ugli Nabiyev
Chemical Technology, Control and Management
This article presents the main stages of the development of an automated system of processes for determining and ensuring functional and parametric compatibility (FPC) of components of production and technological systems (PTS), in particular production and technological modules (PTM) of machine-building production, respectively, based on the analysis and systematization of technological zones of loading of the main technological equipment (MTE) and the construction of coating surfaces, the main parameters of industrial robots and storage systems (SS), determination and mathematical formalization of coating surfaces and guiding planes of MTE loading zones, formation of types of analytical dependences of FPC PTM functions, …

Image Analysis Of Charged Bimodal Colloidal Systems In Microgravity., Adam J. Cecil
Electronic Theses and Dissertations
Colloids are suspensions of two or more phases and have been topics of research for advanced, tunable materials for decades. Stabilization of colloids is typically attributed to thermodynamic mechanisms; however, recent studies have identified transport or entropic mechanisms that can potentially stabilize a thermodynamically unstable colloidal system. In this study, suspensions of silsesquioxane microparticles and zirconia nanoparticles were dispersed in a nitric acid solution and allowed to aggregate for 8-12 days in microgravity aboard the International Space Station. The suspensions were subsequently imaged periodically at 2.5x magnification. Due to the inadequacy of existing image analysis programs, the python package “Colloidspy” …

The main parameters of the electrocardiogram (ECG) were processed on the basis of the neural network apparatus. A decision support algorithm for ECG analysis using a neural network for learning vector quantization is proposed. For the study was chosen such features as the duration of QRS complex, RR interval, amplitude of R-wave and the change in the slope of ST segment and heart rate, which are five inputs to the neural network learning vector quantization. Methods of pre-processing and analysis of extraction of ECG functions based on the ECG database of a medical institution in Matlab are presented. The generalized …
Experimental Analysis Of R134a, R22, And R404 For An Edibon Taab: Air Conditioning Lab Unit, Kyle T. Heesen
Experimental Analysis Of R134a, R22, And R404 For An Edibon Taab: Air Conditioning Lab Unit, Kyle T. Heesen
Senior Honors Projects, 2010-2019
This paper presents an experimental analysis of an Ebidon® TAABTM: Air Conditioning Lab unit running on R-134a being compared with R22 and R404 refrigerants, a $24,449 piece of equipment purchased by the JMU ISAT Department. In this paper we will compare the performance of the R-134a refrigerant under a range of working conditions and compare them to how the system would run on R22 or R404. The experimental tests use varying fan speeds and the R-134a data collected is compared to simulated data collected for R22 and R404. Analysis of the collected data and simulated data will be compared on …
