Testing of Offshore Wind Turbine Positional Controller

A previous mathematical model of an offshore wind turbine was established and then, a positional controller was designed and simulated for a single Wind Turbine in order to provide movement around an area using the force of air that acts on the wind turbine. The goal of my research project is to validate this Position Controller by testing its performance in a real offshore wind turbine system in a controlled environment provided by the host university. By achieving this goal, we will be capable of modifying and controlling the position large-scale offshore wind turbines. This will lead to my second objective that consists on controlling the position of a group of wind turbines, called Wind Turbine Farm, been able to control each wind turbine simultaneously and independently.

Extreme climatic events revealed by tree-ring anomalies in temperate mixed forests of Central China

In dendrochronology, tree-ring widths are used in environment and climate reconstructions. In addition to tree-ring width, wood anatomy and tree-ring anomalies are becoming increasingly valuable as sources of proxy data. The disruption of normal tree growth resulting in various tree-ring anomalies including frost rings, false rings or light rings have been related to climate events such as severe frosts, droughts or cool summers. To our knowledge, only one such study has been done in China where light rings were related to severe droughts. An analysis of tree-ring anomalies in Chinese pine tree species offers the opportunity to address this gap. The purpose of this project is to identify tree-ring anomalies in Chinese tree species and determine their relationship to instrumental records of extreme climatic events in central China. The knowledge of tree-ring anomalies and their calibration to climate data from this study will benefit long-term climate reconstructions, especially where instrumental records are missing and multi-century tree-ring chronologies exist.

Exploring livelihood change in upland rural Hmong villages in Maguan County, Yunnan, China

My Master’s thesis will investigate how ethnic minority livelihoods, specifically those of ethnic minority Hmong (Miao) , have changed in rural Southwestern China over the last 20 years. Hmong communities have traditionally made their livelihoods around household based semi-subsistence agricultural production, based primarily on rice or maize. However, new state policies, technologies, and opportunities are changing the means by which Hmong individuals and households are making ends meet. I will conduct fieldwork in a series of three rural upland villages where I will undertake semi-subsistence interviews, oral histories, potentially complete a photovoice project, and participate in and observe daily life. My aim is to discover the ways Hmong households and individuals are piecing together livelihoods that are both culturally appropriate and situated within the global cash-economy, and the factors that have been directly impacting these livelihood opportunities.

Investigation of LDPE/LLDPE blends foaming behavior based on the high-pressure rheology

Rheology is the branch of physics that deals with the deformation and flow of matter, especially the non-Newtonian flow of liquids and the plastic flow of solids, which is very important in the foaming process. Currently, the rheology of a pure polymer is mainly used to characterize the foamability of polymers. However, the processing conditions, such as high pressure and blowing agent dissolution, exert a significant effect on the rheology. Thus, the investigation of the rheology under the practical conditions is critical for a better understanding of the process and its optimization. The objective of this research project is to correlate the high-pressure rheology of Low density polyethylene (LDPE) and Linear Low density polyethylene (LLDPE) blends with their batch foaming behavior. The high-pressure rheology of LDPE and LLDPE will be characterized, respectively. TO BE CONT’D

Experimental Validation of an Offshore Wind Turbine Control-Oriented Model and Advanced Contoller Implementation

Our laboratory has developed an improved model of large scale offshore wind turbines systems for controller design. This model captures all the important dynamics involved in the system such as the 3 dimensional motion, wave disturbance and wind effects, allowing to design advanced control techniques to enhance the efficacy of the wind turbines and increase their lifespan. The project consists on the experimental validation of this model. Although simulations have been performed achieving promising results, no experimental validation has been done since our home university does not possess a real model and the necessary facilities to run the experiments that the host university has. Once the validation is done I will proceed to design advanced controllers based on this model in order to improve the performance of the offshore wind turbine system. Finally, I will implement these controllers in the real model of the host university and evaluate the performance obtained. If validated, these new controllers will be applicable to large scale wind turbines, maximizing their energy capture and increasing their life span.

Polymorph Screening and Characterization of Active Pharmaceutical Materials

Polymorphs are solid compounds that can take on various forms. Since polymorphs of the same type of material normally exhibit different physical properties, it is very important that polymorphs be known so that useful forms of materials can be consistently controlled in the production process. This project will look at improving pharmaceuticals by finding more polymorphs of materials by polymorph screening, manipulating the external conditions that the materials are subjected to in order to have them undergo polymorphism. This study intends to find new crystal forms that could further be used to improve pharmaceuticals as well as to learn how to prepare polymorphs and operate various characterization apparatus.

Glycoprofiling of Erythropoietin using High Resolution Capillary Electrophoresis-Mass Spectrometry

Erythropoietin is a protein with attached sugars that stimulates the production of red blood cells. As such, it can be used by athletes to enhance their competitive performance, an act that is called doping. Erythropoietin that us used for doping is typically produced in animal cells, which functionalize the protein with sugars that differ from those produced in human cells. Jessica Risley’s project is to develop a method of analysis using capillary electrophoresis coupled to high resolution mass spectrometry to detect this difference in sugars quantitatively and use the information to later test samples to determine whether or not doping has occurred.

Ammonia nitrogen removal from melamine wastewater by biological fluidized bed

The purpose of the research project to be performed at the Zhejiang University of Technology is the study of the hydraulic characteristics associated with removal of ammonia nitrogen and chemical oxygen demand (COD) from wastewater treated in an anaerobic-aerobic fluidized bed. Most of the current biological denitrification processes are performed by some form of biological method but are only suitable for removal of relatively low ammonia nitrogen concentrations due to the requirement of an appropriate carbon to nitrogen ratio. Thus, there is a need to study the hydraulic characteristics of the proposed process in order to determine optimal reactor conditions for ammonia nitrogen removal. The main expected outcome of the research project is the achievement of maximum removal efficiency of both COD and ammonia nitrogen from melamine wastewater, which is made possible by a high resistance to organic loading in the reactor.

Nitrous oxide emissions from fertilized cotton (Gossypium hirsutum L.) under a drip drip irrigation as influenced by nitrogen fertilizer placement depth and rate.

Irrigated cotton (Gossypium hirsutum) in arid areas of China receive very high nitrogen inputs of up to 240 kg/ha-1. The crop also receives large inputs of irrigation water mostly under drip irrigation system. This system will be used to determine the contribution of processes of nitrification and denitrification (microbial processes involved in the production of nitrous oxide) to total nitrous oxide fluxes from the soil. Urea will be applied at different depths and rates. Each microbial process will be linked to these aforementioned variables. The study will be established at the beginning of the cotton cycle with labeled nitrogen (15N) applied to distinguish the contribution of nitrification and denitrification to nitrous oxide fluxes. We expect deeper placement of nitrogen to have a mitigatory effect on nitrous oxide emissions especially when the application rates are high. TO BE CONT’D

Fresh State Characterization of Low-Cement Content Concrete

In 2010 and 2015, the cement industry produced approximately 3.3 and 4.1 billion tons of cement, respectively; hence almost 2 and 2.5 billion tons of carbon dioxide (CO2) were emitted, respectively. Given this rapid growth of CO2 emissions together with the importance of cement in concrete strength development, research studies have focused on approaches to reduce the CO2 of cement consumption. Although it is necessary to reduce cement use to produce a more environmental friendly concrete, it is important to analyze its effects on concrete durability. Reducing the cement content will lower concrete pH, which is normally very alkaline. This could affect concrete durability because high pH values protect against corrosion of the reinforcing steel. This research will characterize the low-cement content concrete on fresh state to conclude how the reduction of cement affects concrete porosity and viscosity, that will change concrete durability.

Shear Behaviour of Concrete affected by Alkali-Aggregate Reaction

The first part of this thesis project consist in a study of the structural behavior, mainly focusing on shear resistance, of concrete elements affected by alkali-aggregate reaction (AAR), an internal swelling reaction. Especially in the presence of moisture, this reaction causes the concrete to expand and form internal cracks. This expansion and formation of cracks is generally associated with a decrease in the mechanical properties of the concrete material. Shear issues of affected concrete is one critical thing to investigate, as they can lead to brittle failures. The chemical and physical processes associated with AAR have now been the subject of considerable research, but there’s a current lack of knowledge with the actual implications on shear performance of affected concrete structures.

Application of the Potts model to find the structure-function relationship of the Brain

Complexity of human brain is limiting our understanding about the mechanisms that dominate its spontaneous activity. An understanding about the architecture of the axonal fibers in the brain and how they support the functions is crucial when it comes to dealing with brain injuries. A mathematical model, was investigated to gain an understanding about the relationship between the structure and the function of the brain. The proposed project aims to extend this understanding by developing a more generalized model to explain the role of the anatomical structure of the brain which is believed to influence brains’ spontaneous activity. Gaining the necessary knowledge about the model as well as the computer simulations are expected by the end of this project as well as a more generalized model which could predict the spontaneous activity of the brain using the distribution of the axonal fiber bundles.
