Exploring The Relationship Of The Closeness Of A Genetic Algorithm's Chromosome Encoding To Its Problem Space, Kevin Mccullough

Master's Theses

For historical reasons, implementers of genetic algorithms often use a haploid binary primitive type for chromosome encoding. I will demonstrate that one can reduce development effort and achieve higher fitness by designing a genetic algorithm with an encoding scheme that closely matches the problem space. I will show that implicit parallelism does not result in binary encoded chromosomes obtaining higher fitness scores than other encodings. I will also show that Hamming distances should be understood as part of the relationship between the closeness of an encoding to the problem instead of assuming they should always be held constant. Closeness to …

Cal Poly Organic Farm Business Plan, Eric Ryan Mccarthy

Agribusiness

This study was undertaken to determine which strategies would allow the Cal Poly Organic Farm to operate as a profitable business without compromising educational and agricultural objectives. Three strategies were analyzed to determine the most profitable approach. The first strategy, expanding CSA sales, emphasizes marketing efforts to increase products and services awareness. This should increase CSA, CPOF, merchandise, and farmers’ markets sales. The second strategy implements new CSA produce boxes that cater to specific groups. Existing produce boxes will remain available to CSA members. Expanding produce boxes can be done with the produce on hand or expanding crop selection. The …

Foraging Rates Of Larval Dragonfly Colonists Are Positively Related To Habitat Isolation: Results From A Landscape-Level Experiment, Shannon J. Mccauley, Tomas Brodin, John Hammond

Biological Sciences

There is increasing evidence of intraspecific variation in dispersal behavior. Individual differences in dispersal behavior may be correlated with other traits that determine the impact individuals have on patches they colonize. We established habitat patches—artificial pools—across a landscape, and these pools were naturally colonized by dragonfly larvae. Larvae were collected from pools at different levels of isolation and held under common lab conditions for 5 months. We then compared larval foraging rates. Foraging rate was positively related to habitat isolation, and colonists from the most isolated artificial pools had significantly higher foraging rates than individuals from the least isolated pools. …

Climate Change And Human Health Consequences, Jennifer Alford

Social Sciences

The intent of this project is to highlight the human health ramifications of climate change and the strategies for coping with this challenge. Possible effects may include reduction in agricultural outputs, dwindling freshwater aquifers, intensification of tropospheric ozone, and expanding areas of disease-carrying vectors. Because humans are closely connected with their environment, we are directly affected by any environmental disturbance. Consequently, human health is vulnerable to the effects of climate change. The questions are: what are those consequences, how will we adapt, and what does the future hold?

Lessons will focus on …

Complying With Proposition 2 Chore-Time Modular Belt Cage System Modifications And The Effects, Angela Coelho, Andrew Demler

Agribusiness

The California poultry industry is at a turning point due to the approaching deadline of Proposition 2 taking effect in 2015. The method of choice to be implemented to stay in business is called an enriched colony cage system. This system is very popular in E.U production, however has yet to be implemented in the United States. Thus, for the purpose of this project the modification of Chore Time® equipment at the Cal Poly poultry unit to resemble colony cages was the taken approach.

The fiscal impact the new law will have on California egg farmers can only be estimated. …

The Implementation Of A Conceptually Coherent Curriculum Within A Constructivist Preschool Environment, Heather Jones, Sarah Post

Psychology and Child Development

Creating a learning environment that enchants children’s curiosity and sparks exploration, discovery, and thought does not require a great amount of financial resources. Rather, one must concentrate on observation and focus on building on children’s existing interests in the natural world. The research and theories of Swiss psychologist and philosopher, Jean Piaget, and Russian Psychologist, Lev Vygotsky provide a concrete look into a child’s cognitive and social development and can be informative in creating such environments. Using the developmental knowledge presented in these theories, programs such as the Reggio Emilia program, the Preschool Pathways to Science program (PrePS), and the …

Feminist Criticism: The Importance Of Sharing The Native Female Journey, Michelle Newfield

Communication Studies

The female Native American perspective is grossly neglected in mainstream media. Sadly, stereotypical images romanticize Native American women in a light that disallows them to be taken seriously in a modernized world. The fact is that the majority of women with American Indian ancestry do not live on reservations; they make up a considerable part of the general population.

There is an unfortunate “invisibility of Native women in comparison to men,” and “Native women are often represented by popular culture within the Plains Indian context, the generic Indian. Omnipresent is the ‘squaw’ who is portrayed as servant, concubine, beast of …

The Critical Decision Vortex: Lessons From The Emergency Room, Jean-François Coget, Eugene Keller

Management, HR and Information Systems

The dominant model of decision making, rational decision making, is increasingly challenged by research on intuitive decision making and emotion. This article contributes to the debate by articulating a model of how rational decision making, intuitive decision making, and emotion influence each other: the critical decision vortex. The critical decision vortex emerges from a discussion between an emergency room (ER) doctor and a management scholar. The experience of the doctor diagnosing and treating patients in the ER provides the background for a reflection on decision making in critical conditions. One of the main findings of this collaborative effort is that …

Temperature Affects Adhesion Of The Acorn Barnacle (Balanus Amphitrite), Laurel A. Johnston

Master's Theses

Biofouling is the accumulation of sessile marine organisms, such as algae, tube worms and barnacles on man-made substrata and has negative economic and ecological implications. Ship hulls are readily fouled, which significantly increases drag while decreasing ship fuel efficiency when moving through water. Fouled hulls have also become important vectors of invasive species. These problems are minimized when hulls are painted with a toxic anti-fouling or non-toxic foul-release coating. Due to recent restrictions of anti-fouling paint use, research and development of non-toxic alternatives has increased.

Novel hull coating efficiency is often quantified by the critical removal stress value of barnacles …

St. Jude Medical: St Monitoring, Anna Marie Kinney

Master's Theses

Myocardial infarction is the leading cause of death in the western world. Time is critical when treating patients with myocardial infarction. The major problem is that many patients who are symptomatic wait too long before seeking medical attention, and some patients have no symptoms at all. In order to improve patient outcome there needs to be a better way to diagnose myocardial infarction. One solution is the continuous monitoring of the ST-Segment of the intrinsic ventricular beat morphology, called the QRS complex. There have been many studies that show that there are detectable shifts of the ST-Segment during coronary occlusion. …

Autonomous Satellite Operations For Cubesat Satellites, Jason Lionel Anderson

Master's Theses

In the world of educational satellites, student teams manually conduct operations daily, sending commands and collecting downlinked data. Educational satellites typically travel in a Low Earth Orbit allowing line of sight communication for approximately thirty minutes each day. This is manageable for student teams as the required manpower is minimal. The international Global Educational Network for Satellite Operations (GENSO), however, promises satellite contact upwards of sixteen hours per day by connecting earth stations all over the world through the Internet. This dramatic increase in satellite communication time is unreasonable for student teams to conduct manual operations and alternatives must be …

Developing A Source Water Protection Plan For Boron In The San Luis Obispo County Water Supply, Jenny Macartney

Master's Theses

The goal of this project is to design a feasible way to develop a protection plan for boron in the surface waters and groundwater of San Luis Obispo County. Boron is a micronutrient needed by all plants and animals but the threshold for toxicity in plants is narrow. As the need for water increases and the production of wastewater and irrigation water infiltrates the soil and waters of the County, an understanding of background soil and water concentrations, as well as anthropogenically produced sources of boron must be quantified and mapped so that intelligent planning decisions can be made.

Variation In The Heat Shock Response And Its Implication For Predicting The Effect Of Global Climate Change On Species' Biogeographical Distribution Ranges And Metabolic Costs, Lars Tomanek

Biological Sciences

The preferential synthesis of heat shock proteins (Hsps) in response to thermal stress [the heat shock response (HSR)] has been shown to vary in species that occupy different thermal environments. A survey of case studies of aquatic (mostly marine) organisms occupying stable thermal environments at all latitudes, from polar to tropical, shows that they do not in general respond to heat stress with an inducible HSR. Organisms that occupy highly variable thermal environments (variations up to >20°C), like the intertidal zone, induce the HSR frequently and within the range of body temperatures they normally experience, suggesting that the response is …

Time-Temperature Curing Relationship Of An Adhesive Binder With Rice Straw, Kevin Ka-Wan Ng

Master's Theses

Rice straw is a global and proliferate agricultural waste whose production grossly outstrips viable uses. Current disposal methods are not sustainable, and more convenient methods – such as incineration – exude poor environmental stewardship. Although the direct use of straw bales in building construction presents a practical and sustainable alternative, engineering challenges associated with using it prevent its wide adoption. The Stak Block – a composite formed from compressed rice straw and a heat-cured adhesive – may overcome challenges associated with straw bale building. However, the times and temperatures needed to cure the binder with straw are not well understood. …

Hormones And Reproductive Cycles In Snakes, Emily N. Taylor, Dale F. Denardo

Biological Sciences

The study of the hormonal regulation of reproduction in snakes is in its infancy. Studies have disproportionately examined temperate zone viperid and colubrid snakes, especially the red-sided garter snake (Thamnophis sirtalis parietalis). Indeed, extensive observational and experimental studies on T. s. parietalis form the basis for our understanding of the hormonal regulation of reproduction in snakes. This review focuses on seasonal hormone concentrations in snakes in relation to events in the reproductive cycle; the limited data available on hypothalamic hormones, gonadotropins (GTHs), hormone receptors, and binding globulins; the neuroendocrinology of reproduction; and the environmental, social, physiological, and embryonic aspects of …
