Analysis Of Experimental Research In Determining Bubbling Extractor Mixing Zones’ Sizes, Karimov Ikromali
Analysis Of Experimental Research In Determining Bubbling Extractor Mixing Zones’ Sizes, Karimov Ikromali
CHEMISTRY AND CHEMICAL ENGINEERING
In the inner mixing zone of the tested suspended extractor, the fluid and gas flows in the stream and the external mixing zone moves in a contradictory flow. In order for these mixing zones to operate equally in hydrodynamic mode, their gas values should be equal. This is achieved by the correct selection of the dimensions of the mixing zones of the liquid and gas. The article summarizes the results of the study of the measurement of the mixing zones of the apparatus.
An Analysis Of Perceptual Masking Between Stems In Manually-Mixed Multitrack Audio Using A Cross-Analytic Loudness Model, Brian H. Cofer
An Analysis Of Perceptual Masking Between Stems In Manually-Mixed Multitrack Audio Using A Cross-Analytic Loudness Model, Brian H. Cofer
Student Theses
In music production, there are many tools available to an audio engineer throughout the mixing process to bring a song to completion. Among the most common are level balancing, equalization (EQ), and compression. However, these tools still require the subjective judgments of human engineers to create the desired listening experience. While automated mixing algorithms have been increasingly studied, they have yet to match the skills of even an amateur mixing engineer, in major part, because the subjective mixing decisions of an engineer are difficult to replicate by automated systems. The following research was developed with the primary goal of objectively …
Effect Of Mixing On Monochloramine Formation Through In-Line Injection Of Chemicals In Water Disinfection Process, Farhikhteh Samadi
Effect Of Mixing On Monochloramine Formation Through In-Line Injection Of Chemicals In Water Disinfection Process, Farhikhteh Samadi
Civil Engineering Dissertations
Addition of chlorine and ammonia to water for monochloramine formation in the secondary disinfection process in treatment plants has some challenges. Monochloramine formation as the only desirable product of the chloramination process is affected by several factors. These factors are pH, chlorine to nitrogen ratio and chemical mixing. In this study an investigation was conducted to measure the effect of mixing on monochloramine formation through direct injection of chemicals in a pipeline when keeping the other factors constant. In this study two sets of experiments were conducted. In the first study a tracer salt testing was used to find a …
Physical Controllers Vs. Hand-And-Gesture Tracking: Evaluation Of Control Schemes For Vr Audio Mixing, Justin Bennington
Physical Controllers Vs. Hand-And-Gesture Tracking: Evaluation Of Control Schemes For Vr Audio Mixing, Justin Bennington
Student Theses
Alternative control schemes for affecting the characteristics of audio signals have been designed and evaluated within the audio research community. The medium of virtual reality (VR) presents a unique method of sound source visualization using a headset which displays a virtual environment to the user, allowing users to directly control sound sources with minimal intermediary interference with a variety of different controllers. In order to provide insight into the design and evaluation of VR systems for audio mixing, the differences in subject preference between physical controllers and hand-and-gesture detection controls were investigated. A VR audio mixing interface was iteratively developed …
Listener Evaluation Of Common Drum Recording And Mixing Techniques, Tucker W. Arbuthnot
Listener Evaluation Of Common Drum Recording And Mixing Techniques, Tucker W. Arbuthnot
Student Theses
This thesis explored whether listeners could perceive the differences between samples recorded and mixed according to methods reported by the so-called popular audio press and samples that did not utilize those methods. The three recording methods were: aligning multiple tracks to achieve a coherent phase relationship, microphone selection, and the style of recording. The three mixing methods were: inverting the bottom snare drum microphone to match the top snare drum microphone, having a pre-delay time on a reverb that matched the tempo of the sample, and routing the room microphones to the drummer’s perspective. ABX listening tests, preference surveys, and …
The Effects Of Scale On Granular Mixing In A Double Screw Pyrolyzer, Breanna L. Marmur
The Effects Of Scale On Granular Mixing In A Double Screw Pyrolyzer, Breanna L. Marmur
Breanna L. Marmur
Granular mixing processes are important to many industries including the pharmaceutical, agricultural, and biotechnology industries. These processes often require both a high degree of homogeneity and a high degree of customizability. As granular mixing processes are so widely employed, a thorough understanding of the mixing dynamics is necessary to understand and control the resulting products. Research into granular mixing processes has been, thus far, largely focused on laboratory scale mixers with simple geometries, while actual industrial processes often require large mixers with complex geometries. Moreover, granular mixing processes are often very sensitive to changes in operating conditions and any solutions …
