In Memory Computation Of Glowworm Swarm Optimization Applied To Multimodal Functions Using Apache Spark, Goutham Miryala Jan 2018

In Memory Computation Of Glowworm Swarm Optimization Applied To Multimodal Functions Using Apache Spark, Goutham Miryala

Computer Science

Glowworm Swarm Optimization (GSO) is one of the optimization techniques, which need to be parallelized in order to evaluate large problems with high-dimensional function spaces. There are various issues involved in the parallelization of any algorithm such as efficient communication among nodes in a cluster, load balancing, automatic node failure recovery, and scalability of nodes at runtime. In this paper, we have implemented the GSO algorithm with the Apache Spark framework. The Spark framework is designed in such a way that one does not need to deal with any parallelization details except the logic of the algorithm itself. For the …

Health Risk Prediction Using Big Medical Data - A Collaborative Filtering-Enhanced Deep Learning Approach, Xin Li Jan 2018

Health Risk Prediction Using Big Medical Data - A Collaborative Filtering-Enhanced Deep Learning Approach, Xin Li

Computer Science

Deep learning has yielded immense success on many different scenarios. With the success in other real world application, it has been applied into big medical data. However, discovering knowledge from these data can be very challenging because they normally contain large amount of unstructured data, they may have lots of missing values, and they can be highly complex and heterogeneous. In these cases the deep neural network itself is not applicable enough. To solve these problems we propose a Collaborative Filtering-Enhanced Deep Learning Approach. In particular, first we estimate missing values based on the information mining from the structured and …

An Integrated Approach To Assess The Impacts Of Zinc Pyrithione At Different Levels Of Biological Organization In Marine Mussels., Lorna J. Dallas, Andrew Turner, Tim P. Bean, Brett P. Lyons, Awadhesh N. Jha

School of Geography, Earth and Environmental Sciences

The mechanisms of sublethal toxicity of the antifouling biocide, zinc pyrithione (ZnPT), have not been well-studied. This investigation demonstrates that 14-d sublethal exposure to ZnPT (0.2 or 2 μM, alongside inorganic Zn and sea water controls) is genotoxic to mussel haemocytes but suggests that this is not caused by oxidative DNA damage as no significant induction of oxidised purines was detected by Fpg-modified comet assay. More ecologically relevant endpoints, including decreased clearance rate (CR), cessation of attachment and decreased tolerance of stress on stress (SoS), also showed significant response to ZnPT exposure. Our integrated approach was underpinned by molecular analyses …

Blood Glucose Prediction Models For Personalized Diabetes Management, Warnakulasuriya Chandima Fernando Jan 2018

Blood Glucose Prediction Models For Personalized Diabetes Management, Warnakulasuriya Chandima Fernando

Computer Science

Effective blood glucose (BG) control is essential for patients with diabetes. This calls for an immediate need to closely keep track of patients' BG level all the time. However, sometimes individual patients may not be able to monitor their BG level regularly due to all kinds of real-life interference. To address this issue, in this paper we propose machine-learning based prediction models that can automatically predict patients BG level based on their historical data and known current status. We take two approaches, one for predicting BG level only using individual's data and second is to use a population data. Our …

Using Human Error Models To Improve The Quality Of Software Requirements, Vaibhav Kumar Anu Jan 2018

Using Human Error Models To Improve The Quality Of Software Requirements, Vaibhav Kumar Anu

Computer Science

Creating high quality software is a primary concern for software development organizations. Researchers have devoted considerable effort in developing quality improvement methods that help software engineers detect faults early in the development lifecycle (when the faults are cheapest to detect and repair). While useful, the available approaches still cannot make sure that Software developers are able to identify all or even a significantly large portion of faults. This is because they do not help software developers identify errors (i.e., underlying cause of faults) that may have led to the insertion of the faults (i.e., manifestation of error). This lack of …

Scalable Algorithms For Mining Maximal Quasi Frequent Subnetworks, Eihab Salah El Radie Jan 2018

Scalable Algorithms For Mining Maximal Quasi Frequent Subnetworks, Eihab Salah El Radie

Computer Science

Frequent graph mining has received considerable attention from researchers. Existing algorithms for frequent subgraph mining do not scale for large networks, and take hours to finish. Mining multiple gene coexpressions networks allows for identifying context-specific modules. Frequent subnetworks represent essential biological modules. In this thesis, we propose two algorithms for mining frequent subgraphs. In the first algorithm, we propose a parallel algorithm for mining maximal frequent subgraphs from gene coexpression networks. Despite the algorithm’s parallelization, it takes much time and it does not allow relaxation. This inspired us to develop a second algorithm that solves those problems. In the second …

Mining Structure Patterns Based On 3d Features In The Protein-Dna And Protein-Protein Complex, Qing Sun Jan 2018

Mining Structure Patterns Based On 3d Features In The Protein-Dna And Protein-Protein Complex, Qing Sun

Computer Science

For a long time, researchers have been searching for the “recognition codes” of protein complexes, which determine what DNA sequence or other protein a protein can bind to. The binding part prediction of protein complexes have important applications in many biological research fields, such as cleavage enzyme design and drug design and so on. Most sequence-based and PWM methods only capture sequence features on the protein interfaces and ignore the crucial spatial attributes of the features. This study investigates the recognition codes from a new angle, in which the preferred binding modes are captured using local structural motifs spanning the …

Deception In Cyberspace: Con-Man Attack In Cloud Services, Md. Minhaz Chowdhury Jan 2018

Deception In Cyberspace: Con-Man Attack In Cloud Services, Md. Minhaz Chowdhury

Computer Science

A con-man deception appears in services from cyberspace, e.g., in cloud services. A cloud-service provider deceives by repeatedly providing less service than promised and deliberately avoids service monitoring. Such a repeated shortfall is beneficial for the cloud-service provider but victimizes the service’s legitimate consumers. This deception is called a con-man deception. A con-man-resistant trust algorithm is used as a proactive measure against such deception, reducing the deception’s severity on the victim’s end. This trust algorithm detects a con-man deception by evaluating a cloud service’s expected versus actual behavior. This detection application reveals the con-man-resistant trust algorithm’s previously veiled properties. With …

Within And Without: St. Paul Museum Of Architecture, Mitchell Abrahamsen

Architecture Theses

This thesis project revolves around how museums influence our perception of objects and ideas. Through research on museum design and architectural theory, I have come to understand the idea of framing and its importance in how museums and museum exhibits are designed. Framing, in an abstract sense, is the foundation from which our perceptions are built. The same object, space, or idea can be framed in different ways and will therefore be perceived differently. Framing in museums an be very literal, such as a wooden frame around a painting, and it can be more metaphorical, such as the spatial volume …

Developing A New Powered Seed Delivery System With Constant Seed Release Speed Using Two Confronting Belts, Mojtaba Ahmadi Jan 2018

Developing A New Powered Seed Delivery System With Constant Seed Release Speed Using Two Confronting Belts, Mojtaba Ahmadi

Agribusiness and Biosystems Engineering

Seed delivery devices are aimed to carry seeds down to open furrow that might affect uniformity of plant stand and spacing. The objective of this study was to develop and evaluate a new seed delivery system utilizing a two-belt mechanism configuration for sunflower (Helianthus annuus). A prototype were fabricated and tested with MeterMax® Ultra Test Stand in order to evaluate the new seed delivery system. The outcomes show that dependent variables like seed population, singulation, skips, and multiples rates were not affected by planting speed levels (Pvalues > 0.05), while planting speed had a negative effect on seed spacing consistency (P-values < 0.05). In addition, due to facing broken seeds during test process, multiples rate were between 8.0 to 9.5% and consequently affected other variables as well. To improve this mechanism and avoid the systematic error that caused by broken seeds, this system should be redesigned in a single-belt form.

The Effects Of Maternal Diet On Passive Transfer Of Immunity To The Neonatal Beef Calf, And Calf Immune Response To Vaccination And Immunostimulants, James Joseph Gaspers Jan 2018

The Effects Of Maternal Diet On Passive Transfer Of Immunity To The Neonatal Beef Calf, And Calf Immune Response To Vaccination And Immunostimulants, James Joseph Gaspers

Animal Sciences

To investigate the effects of maternal diet on passive transfer of immunity to the neonatal beef calf, and calf immune response to vaccination and immunostimulants, three experiments (Exp.) were completed. Results from Exp. 1 indicated that there was no effect of supplemental starch to cows on colostrum production, offspring birth weight, incidence of dystocia, respiratory acidosis, and the passive transfer of immunity. Results from Exp. 2 indicated that both the needle – free injection devices (NFs) and needle and syringe (NS) initiate a haptoglobin (Hp) inflammatory response (P < 0.001). After injection bovine viral diarrhea virus (BVDV) type 2 antibody titers continually declined from d 0, 7, 28, and 115 across both NS and NF treatment groups (P < 0.001). After secondary booster vaccination on d 115, BVDV type 2 antibody titers significantly increased by d 143 (P < 0.001). The use of NFs will maintain a level of immunity that has been seen by the use of conventional NS vaccine administration methods. In Exp. 3, treatments containing a modified live vaccine (MLV) antigen initiated an Hp inflammatory response over time (P < 0.001). Interferon gamma was not significantly different across treatment over time (P = 0.39); however, there was a threefold increase in treatment three over time. Treatments containing a MLV BVDV antigen maintained BVDV type 2 antibodies over time (P <0.001). Feed intake and feeding behavior were unaffected by the use of the vaccine and/or immunostimulant.

Distributed Electric Propulsion Effects On Traditional Aircraft Through Multidisciplinary Optimization, Kevin Moore, Andrew Ning Jan 2018

Distributed Electric Propulsion Effects On Traditional Aircraft Through Multidisciplinary Optimization, Kevin Moore, Andrew Ning

Faculty Publications

Electric aircraft face a steep tradeoff between the demand for runway performance and range. While fuel based propulsion technologies typically increase in specific power with increasing size, electric propulsion is typically much more scalable. This system scalability enables alternative designs including distributed propulsion, optionally powered propulsion units, and vectored thrust, which can all contribute to better runway performance and range. In this paper, we explore how continuously powered distributed propulsion can reduce takeoff distance while still satisfying range constraints. We use a combination of a blade element momentum method, a vortex lattice method, experimental data, and nonlinear optimization techniques to …

Benefits Of Two Turbine Rotor Diameters And Hub Heights In The Same Wind Farm, Andrew Pj Stanley, Andrew Ning, Katherine Dykes Jan 2018

Benefits Of Two Turbine Rotor Diameters And Hub Heights In The Same Wind Farm, Andrew Pj Stanley, Andrew Ning, Katherine Dykes

Faculty Publications

Significant turbine-wake interactions greatly reduce power output in a wind farm. If different turbine hub heights and rotor diameters are included in the same wind farm, the wake interference in the farm will be reduced, resulting in a lower cost of energy (COE) than a farm with identical turbines. In this paper, we present a method to model wind farm COE in farms with hub heights and rotor diameters that vary across the wind farm. We also demonstrate how to optimize these wind farms to minimize COE. The results show that COE can be greatly reduced in wind farms with …
