PROJECTS ANALYSIS OF ELECTROENCAPHALOGRAPHIC DATA OF ALCOHOLICS
Supervisors: Professor Ramsey Saunders and Mr. Oba Ranu
Number of Students: 2
The analysis of the record of the electrical signals for the surface of the head, the Electroencephalogram (EEG), can potentially yield important information on the diseased states as well as the state of wellness of an individual. Alcoholism is a classicstate for testing this hypothesis. The State University of New York (SUNY) has made available to us twenty (20) years of resting EEG measurements on alcoholic patients from a large scale study in the U.S. Two students are required to analyse these data using neurometric analysis and coarse grained dimensional analysis (Chaos).
Medical Physics students required.

Development of new electrolyte membranes as separators for application in Polymer Electrolyte Membrane Fuel Cells
Summary of the project:
In this project the aim will be to develop new/novel electrolyte/membrane materials for applications in two different types of fuel cells viz. polymer electrolyte membrane fuel cells (PEMFC’s) and direct methanol fuel cells (DMFC’s). The start will be done with reviewing the literature and systems will be decided. The aim will be to find/develop new materials for developing the membranes and then developing them by using various techniques (acid/base, Ionic liquid etc). The developed membranes are expected to show better properties than the commercial Nafion materials and should also achieve all the favourable properties required at less cost. The membranes developed will be characterized for various properties like electrical, thermal, morphological, ion transport, swelling, mechanical properties etc. and will be further tested for their suitability in fuel cells.
Materials Science students/ or students with chemistry interest/background preferred.

Linkage between Geomagnetic activity, variability of Total ozone during the Hurricane season over the Atlantic Ocean.
Summary
During solar activity, many energetic particles enter the Earth’s magnetic field. When they reach the middle of the atmosphere, they ionize the atmospheric gases, resulting a change in the atmospheric ozone. These variations in the ozone density modulate the amount of UV radiation reaching the lower atmosphere, with a consequent variation in heating that would lead to temperature changes and changes in atmospheric circulation pattern. Evidences of the solar activity modulation of the Earth’s climate have been observed on different time scales. This project is another attempt to investigate the linkage between Geomagnetic activity and ozone during July- September over a period of five years(2003-2007).

EXTRASOLAR PLANETS
Several methods for searching for extrasolar planets are possible. This projectwill utilize the transit method and involves using the SATU telescope to do preliminary testing and searching for extrasolar planets and determining physical characteristics of the objects monitored. It will involve night time work. The observatory on the roof has facilities for overnighting. Image processing will be required. It would be useful if the student has already completed PHYS 3383.

ASTROBIOLOGY
The question of the origin and existence of life in the Universe is one of the big astronomy questions in recent times. Astrobiology is a multidisciplinary field that seeks to gain insight into the ability for organisms to exist in extreme and hostile environments. This project involves sampling and testing from the mud volcanoes and the pitch lake in La Brea as two analog sites for Mars and Saturn’s moon Titan respectively. Background into Chemistry and Microbiology will be an asset.

Development and Assessment of Visualizations/Animations for the Teaching of Nuclear and Radiation Physics to Medical Students
Exposure to physics and physics concepts may not only be an essential part of the education of the natural scientist but also of students and researchers in the fields of health and medical sciences. It is often the case in the health and medical sciences that students must quickly learn to deal with advanced physics concepts. Often, they may have had limited exposure to the field of physics or have made little use of previous education in the field for many years. Many methods can be utilized to improve theteaching and learning of physics to these specific groups. One method/tool which is believed to significantly influence students’ understanding and visualization of physics concepts is the use of digitized video and animations. The project will focus on the development and assessment of visualizations/animations for the teaching of nuclear and radiation physics to medical students. The visualizations will be developed using the vector graphics editors (e.g Inkscape and EVE), however any other suitable software program, with which the student is familiar, may be used.

EVALUATING THE PERFORMANCE OF AN EVACUATED TUBE COLLECTOR SOLAR WATER HEATER
Solar water heaters incorporate many different designs, such as Plat Plate collector technology and Evacuated Tube collector technology. Extensive analysis on the performance of the flat plate collector design has been performed for the Caribbean context. This project aims to evaluate the performance of an evacuated tube collector solar water heater for the Caribbean situation. The usable heat produced can be utilised for water heating, space heating, and space cooling by the use of an absorption chiller or dessicant cooler technology.

GEOPHYSICAL SURVEY AT THE DEVIL'S WOODYARD AND PIPARO MUD VOLCANOES
For a number of years the Department of Physics has been monitoring activity and environmental-related issues at Trinidad’s major mud volcanoes. In addition to surface indicators and mineralogical characteristics, emphasis is focused mainly on seismic and resistivity subsurface probing and X-ray diffraction mineralogical analysis. The project will serve as the 2008 input into the on-going monitoring programme.

Development of the protocol to ensure quality assurance in the delivery of services in the Radiology Department at the E.W.M.S.C.
One of the essential responsibilities of a qualified Medical Physicist in the clinical environment is to assure the safe and effective delivery of ionizing and non-ionizing radiation for the diagnosis and treatment of disease. In this context, quality assurance is defined as the planned and organized actions necessary to provide adequate confidence that equipment for diagnostic imaging will produce quality diagnostic results reliably, with minimal radiation exposure to patients and staff. As such, a quality assurance program is essential to any radiological department. It ensures that: 1. All equipment are operating within specified parameters 2. Images acquired are accurate and reproducible 3. Patients and occupational workers are not exposed to ionizing radiation exceeding recommended international standards. 4. Any deviations in the operation of the instruments are detected early so that: complete failure is minimized failing components can be ordered before hand instrument downtime is reduced it translates to better overall patient care The student will be responsible for setting up and testing respective protocols for selected instrumentation used by the Radiology Department at the E.W.M.S.C. Some operational parameters that may be determined are image noise, CT number values, CT number uniformity, CTDI, irradiated slice thickness and high contrast spatial resolution.
