Study Of Rehydration Properties Of Powder Produced From Chelated Skim Milk, Kristina Ellice Tan

Master's Theses

Poor rehydration properties of skim milk powder (SMP) can impact processing efficiency and functionality in finished product applications. Rehydration can be split into four stages: wettability, sinkability, dispersibility, and solubility. Previous work has suggested that chelator addition during SMP manufacture leads to higher solubility compared to SMP without chelators. This study focuses on the addition of ethylene diamine tetraacetic acid (EDTA) or sodium citrate dihydrate (SCD) at concentrations of 5, 10, and 15 mM to skim milk prior to evaporating and spray drying. The objective of this investigation was to determine the effects of the chelator additions on each SMP …

Effect Of The 2013-2015 California Drought On Small Mammal Abundance And Diversity In Chaparral, Oak Woodland And Riparian Habitats, Nicole Desideri

Biological Sciences

Long-term biodiversity surveys are a useful tool for assessing the impacts of stochastic events on wildlife and their communities. A recent stochastic event to affect the state of California is the historic 2013-2015 drought. This drought, described as a one-in-one-thousand year event, brought precipitation to a historic low; the statewide rainfall reaching 34% below average (Swain et al. 2014). While humans are feeling the impact of this water shortage, the effects on native ecosystems and wildlife populations are poorly documented. Baseline small mammal biodiversity data collected in 2011, before the drought, allows us the opportunity to study the impacts of …

Magnetic Bearing For Bently Nevada Rk4 Rotor Kits, Sean Fowler, Garrett Olson

Mechanical Engineering

Active Magnetic Bearings (AMB) are contact free bearings that support loads by magnetic levitation. This is accomplished by generating magnetic forces with electric current through a series of electromagnets surrounding a suspended rotor mass. Along with a set of electromagnets, an AMB assembly also consists of power amplifiers for each electromagnet, a controller, and proximity sensors. The proximity sensors provide rotor position feedback to the control system, which modulates power to the amplifiers [4]. Magnetic bearings are used in several industrial applications today, including but not limited to compressors, turbines, pumps, motors, and generators. Advantages of their utility include very …

The Effects Of Latency On 3d Interactive Data Visualizations, Allen Korenevsky

Master's Theses

Interactive data visualizations must respond fluidly to user input to be effective, or so we assume. In fact it is unknown exactly how fast a visualization must run to present every facet within a dataset. An engineering team with limited resources is left with intuition and estimates to determine if their application performs sufficiently well.

This thesis studies how latency affects users' comprehension of data visualizations, specifically 3D geospatial visualizations with large data sets. Subjects used a climate visualization showing temperatures spanning from the 19th to the 21st century to answer multiple choice questions. Metrics like their eye movements, time …

Music And Language Development: Traits Of Nursery Rhymes And Their Impact On Children's Language Development, Ashley Lauren Gonzalez

Music

From birth--possibly even before birth--the amount and array of external stimuli profoundly affect a child’s cognitive and linguistic development. In addition to verbal communication from parent to child, singing proves to be an integral aid to a child’s development of speech and language, allegedly due to repetitions of words and rhythms. Nursery rhymes are, from infancy, among the most commonly presented forms of musical stimulus for children. The repetitive nature of the nursery rhymes undoubtedly supports language and speech development, but various characteristics of nursery rhymes, specifically pitch interval, meter, phrase length, contour, and harmony, also contribute substantially to the …

Commercial Vertical Farm Design Phase 1, Tyler Tappin, Bryan Gomes

Architectural Engineering

Until recent years, vertical farming, or urban agriculture, has usually been referred to as more of a science fiction concept than a realistic means of production. However, it is becoming increasingly apparent that these urban crop­growing structures are not only technologically feasible, but efficient. These structures are entering the realm of economic feasibility as well, appearing in niche markets near large cities. Most of the facilities, however, are generally restricted in size to single­story buildings. The objective of this project was to design a multi story structure that would be well­equipped to house a large vertical farming operation. Some of …

Rapid Battery Exchange (Rbx), Daniel Rostom

Electrical Engineering

Electric vehicles have begun to hit the main stream market, with sales raising form under 20,000 in 2001 to over 110,000 per year since 2014 [1]. With new models hitting the market every year, and more people becoming conscious about their fossil fuel usage, this trend will only continue until there are more electric vehicles than combustion vehicles on the road. A major drawback of electric vehicles is their limited range, and relatively long recharge times.
