Power Flow control in HVDC Grid and its effect on the underlying AC power system stability.

HVdc is the preferred approach for transmission of bulk power into existing AC network from point to point and from remote generation resources because of technical advantages, including low transmission losses. Integration of HVdc grid with existing AC grid provides considerable economic benefits while throwing up challenges for effective control of both the grids at the same time. This project proposes to study through simulations and come up with suitable recommendations for the following: (a) The effect of transfer of bulk power through HVdc grid into existing AC grid and the stability of AC network arising out of fast transients related to converters, (b) Impact of bulk power from HVdc on slower dynamics of the generators located at far places. The presently-used simulation technique takes a long time, as the systems become large and complex with real plant data. In the proposed study, these complex power systems will be simulated on a platform by splitting / parallelization to get faster results. The study will thus result in better understanding of operation of HVdc grid and will aim to develop an optimized control scheme for effective control of such a system.

Evaluating the Impact of a Mobile Unit in a Cancer Screening Program Among Vulnerable Populations in Brazil

In Brazil, inequities in accessing healthcare are linked to socioeconomic disparities. Poor and middle-income countries – like Brazil – bear the highest burden of cancer morbidity and mortality; yet typically do not have structured screening programs. My research aims to evaluate an innovative program in Brazil for screening breast, cervical, prostate and skin cancer. To combat inequities in access to healthcare, Brazil has implemented mobile units (MUs) to
proactively reach vulnerable populations and provide essential screening and health promotion services. My research will investigate the effectiveness of MUs in Brazil, including statistical analysis on the increase of early detection and the reduction in complications that occur due to invasive cancer. I will also be assessing operational measures of MUs (e.g., cost and viability). The research findings will provide an assessment of Brazil’s MU program intended to inform decision-making at local, national and international levels, as well as how similar interventions for vulnerable populations can be implemented elsewhere. Improving cancer screening can save lives, reduce treatment costs, and reduce inequalities in avoidable cancer mortality.

Nitrosation of dimethylformamide (DMF) wastewater in fluidized bed biological reactors

DMF is a toxic organic compound used in various industrial processes. It has been linked to causing cancer and assorted birth defects, and therefore is a dangerous compound to have in wastewater. The process of nitrosation is simply the conversion an organic molecule into a nitroso derivative, essentially a molecule with a nitrogenoxygen functional group. This process will turn the toxic DMF into a safe non-toxic compound. We expect to see different levels of DMF degradation depending on the setting of the reactor. By changing parameters such as pH (acidity or alkalinity) we hope to find the most effective and efficient way to degrade DMF in wastewater.

Green and Controlled Synthesis of Chiral Compounds

Organocatalysis is a method used where the rate of reaction is increased by an organic catalyst, referred to an an organocatalyst. The use of an organic compound eliminates the need to use a metal catalyst, deeming the project as “green”. The absence of the metal catalyst means there is no need for the expensive recovery process during waste treatment and there is no risk of metal leakage. Organocatalysis are particularly useful because they allow for the production of many complex structures through multicomponent, multi-step or tandem reactions using relatively inexpensive compounds. The objective of this lab is to develop a new class of organocatalysts that incorporate both functionalities, NHCs and thiourea functionalities in a chiral scaffold. The combination these two grounps has never been investigated, however has the potential to lead to the generation of new organocatalysts important for many important transformations.

Determination of Solubilities of CO2 in Brines Under Geological Storage Conditions

More and more attention is being paid to the sequestration of CO2. The proposed methods for CO2 sequestration include geological sequestration, ocean sequestration, mineral sequestration, and so on. Among them, saline aquifers in geological sequestration can store the largest amount of CO2, and is the most promising method. At present, the study of CO2 sequestration in saline aquifers remains at the stage of modeling prediction. Even though
numerous experimental data for the solubility of CO2 in CO2-H2O-NaCl system are available, data in certain P-T-x conditions are still lacking, especially in the saline systems containing additional Ca2+, Mg2+, and SO4 2- ions, and their effects on the large-scale injection of CO2 to saline aquifers. We plan to simulate the CO2 sequestration environments in saline aquifers, using our originally designed visual capillary device, in combination with in-situ Raman spectroscopy and/or microscopy technology, to study solubility of CO2 in brines (contains Na+, Ca2+,Mg2+,Cl-,SO4 2-) at relevant P-T conditions.

In situ synthesis and characterization of cellulose Ag/AgCl composite photocatalyst

The research project I will be working on at Tianjin University is called the “in situ synthesis and characterization of cellulose Ag/AgCl composite photocatalyst.” During this project, we will be working with lignocellulosic-based composites, which have many applications in biology, medicine, dirt degradation, and wastewater treatment. A composite is defined as a material made of two different materials, each with different properties. In the case of this project, we will be using cellulose acetate and different amounts of silver to form our composite. By producing many different membranes of these composites, with different amounts of silver, we will be able to test their broad range of applications. In doing so, we believe we can determine the
relationships between the different composites and their physical and chemical properties.

Synthesis of hierarchical porous Ti-ZSM-5 and it’s performances for alkylation of benzene

The alkylation of benzene is receiving increased attention in petrochemical industry. This is because it is potentially an alternative to produce xylene (used in production of polyester and plastic water bottles) from coal and natural gas. It is expected that changing the acidity of the reaction catalyst would improve the utilization of methanol in the reaction. A more efficient catalytic benzene alkylation, using methanol, will decrease production costs as well as energy consumption. This project is also about broadening my research skills and creating global academic network. It will allow me to gain a greater understanding of research processes and expand on my learning from my engineering studies.

Catalytic Reforming, Hydrogenation, and Decarboxylation of Unsaturated Fatty Acid Esters over Non-noble Metal Catalyst

Biodiesel refers to a vegetable oil or animal fat based diesel fuel consisting of saturated and unsaturated long-chain alkyl esters. Low value biodiesel has been developed on a commercial scale, however the application is limited. The conversion of biodiesel to high value C8-16 n-alkanes currently uses metal catalysts (Pt/C), which is an expensive technique. Designing and preparing non-noble catalysts, such as Ni and Fe based catalysts, is important
for the commercialization of biodiesel carboxylation technology. The purpose of this project is to develop a catalyst that will catalyze the process of reforming, hydrogenation, and decarboxylation for the conversion of unsaturated fatty acid esters to n-alkanes found in aviation fuel.

High-efficiency DC-DC converter for TFT touch sensors

This project aims at designing a high-efficiency DC-DC converter for TFT touch sensors. The main task of the converter is to step-up the low and variable input voltage to a higher and more stable voltage that is able to power the touch sensor. The most challenging part of the design is the regulation of the converter, especially since the touch sensor can be powered by different sources such as rechargeable batteries and USB interconnections. The design will be modelled, simulated, and optimized until it is able to achieve the required efficiency. The design will be fabricated and integrated as part of a complete sensor system.

Educational Math Games For Developing Countries

Hundreds of millions of children in developing countries are unable to complete primary education. Mobile devices such as tablets are increasingly inexpensive and becoming accessible in large numbers in such developing countries. We propose developing educational software for such tablets to help children acquire arithmetic skills. To do this, we will develop new ways of gamifying math operations, to apply the principle that says that the gameplay in educational games should have users perform the very skill that they are meant to develop. To do this, we propose breaking down math operations into small steps, each of which can be performed with gestures or with textual input, with appropriate feedback at each step to guide or confirm the user’s actions. We will design and prototype such gamifications in software for mobile devices and evaluate them with primary school students. Beyond this initial project, in the future, we hope to pursue field evaluations with students in India.

The luminescence of cavitation bubble generated by spark discharge in water

Cavitation bubble can be generated by ultrasound, laser or spark discharge underwater. It has good potential in the application of medical treatment, environmental treatment and surface cleaning. When the bubble collapse, the vapor inside will be compressed quickly and the temperature will rise to several thousand Kelvin, even reach ten of thousand Kelvin, and the pressure inside is around several hundred atm. Under such condition, there will be luminescence phenomena inside of the bubble if its energy is large enough. In this project, we want to use simulation and experimental methods to study the luminescence inside of the cavitation bubble. The temperature and pressure variation will be simulated and the intensity and spectrum characteristic of luminescence will be
studied by using high speed photography and emission spectra methods.

Integrating physics and geology for an improved understanding of rock deformation

The relationship between the structure of rocks near the Earth’s surface and their geophysical properties is little understood. Rock samples from a large, exposed fault will be collected from Serifos, Greece, a region strongly affected by earthquakes and recent tectonism. These samples preserve varying degrees of deformation and structural complexity. The amountof deformation affects the orientations of a rock’s crystals as well as their magnetic properties, consequently influencing the behavior of seismic (earthquake) waves propagating through these rocks. Quantitatively characterizing these parameters will contribute to a better understanding of seismic anisotropy, which is the variation in seismic wave velocities depending on their propagation direction in a material. This in turn will enable more accurate large-scale models of the Earth’s interior and further understanding of earthquakes in densely populated areas, like Greece. The project will comprise Gaudreau’s Bachelor’s Honours Thesis and results will be presented at the international European Geoscience Union (EGU) in Vienna in April 2016.
