Usability Simplified: A Basic Guide To Undertaking Effective Usability Testing, Garrison Reeves Apr 2016

Usability Simplified: A Basic Guide To Undertaking Effective Usability Testing, Garrison Reeves

Professional Writing and Information Design Capstone Projects

Usability can be complicated but I provide simple guidelines to effective usability. Every product has an intended purpose, and the scope and aim of usability testing is measuring if a product meets this purpose with regards to a user. Testing is used in many fields, but I intend to focus on user-centered interaction design and how to test when designing and developing such a product. I provide a simple head-start to usability testing based off of my research. Usability testing is a technique used for evaluating a product by testing the product on users who are part of the respective …


Economic Efficiency In Fisheries And Aquaculture, Paul Molyneaux Apr 2013

Economic Efficiency In Fisheries And Aquaculture, Paul Molyneaux

The Catch

Reflection of the author as a worker looking to make the best use of his time and energy. His innate understanding of the principles of ecological economics followed by exposure to the discipline’s advancing theories leads to a revelation regarding the backwards logic of fisheries and aquaculture policy thus far, and the decline in real seafood production.Along with many others, Molyneaux looks to ecological economics to create a new paradigm for sustainable fisheries.


Innovative Desalination Systems Using Low-Grade Heat, Chennan Li Apr 2012

Innovative Desalination Systems Using Low-Grade Heat, Chennan Li

USF Tampa Graduate Theses and Dissertations

Water and energy crises have forced researchers to seek alternative water and energy sources. Seawater desalination can contribute towards meeting the increasing demand for fresh water using alternative energy sources like low-grade heat. Industrial waste heat, geothermal, solar thermal, could help to ease the energy crisis.

Unfortunately, the efficiency of the conventional power cycle becomes

uneconomically low with low-grade heat sources, while, at the same time, seawater desalination requires more energy than a conventional water treatment process. However, heat discarded from low-grade heat power cycles could be used as part of desalination energy sources with seawater being used as coolant …


Synthesis And Characterization Of Nanocomposites For Electrochemical Capacitors, Farah Alvi Feb 2012

Synthesis And Characterization Of Nanocomposites For Electrochemical Capacitors, Farah Alvi

USF Tampa Graduate Theses and Dissertations

Presently there are deep concerns over the environmental consequences and the consumption of non-renewable energy sources, with the accelerated greenhouse effect, triggered enormous interest in the use of renewable energy sources e.g., solar, hydropower, wind and geothermal. However the intermittent nature of harvesting renewable energy sources has recently gained considerable attention in the alternative reliable, cost effective, and environmentally friendly energy storage devices. The supercapacitor and lithium ion batteries are considered more efficient electrical energy storage devices than conventional energy storage systems.

Both devices have many useful and important applications; they could be an excellent source for high power and …


Smart Grid Functionality Of A Pv-Energy Storage System, Nenad Damnjanovic Jan 2011

Smart Grid Functionality Of A Pv-Energy Storage System, Nenad Damnjanovic

USF Tampa Graduate Theses and Dissertations

Renewable Energy will be the key to preserving the Earth's remaining resources and continuing this surge of technological progress that we have experienced this past century. New philosophies of how/when/where energy should be consumed and produced are attempting to improve upon the current grid infrastructure. The massive advancement in communications, renewable and control systems will allow this new-age electric grid to maximize its efficiency while reducing cost. Renewable, "green" energy is now at the forefront of innovation. As the world population increases, there will be a need to free ourselves from natural resources as much as possible. Advanced Energy Storage …
