Fiber Reinforced Composites Of A Novel Pendent Polyimide: Optimum Processing And Mechanical Properties, Akshay Kamdar
Fiber Reinforced Composites Of A Novel Pendent Polyimide: Optimum Processing And Mechanical Properties, Akshay Kamdar
Theses
A 2-component polyimide [3,4'-ODA + 4,4'-ODPA], a 3-component "parent" polyimide [3,4'-ODA + 4,4'-ODPA + 10 mol % Mellitic acid dianhydride (MADA)] and a 4-component "pendent" polyimide [3,4'-ODA + 4,4'-ODPA + 10 mol % MADA + 10 mol % Zr] were synthesized and characterized using fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) techniques. Since temperature and time are critical factors influencing the thermal and mechanical properties of the final polyimide, it is important to have detailed information on the best time-temperature conditions for imidization and cure in order to optimize the processing and properties of …
Support Vector Machines For Image And Electronic Mail Classification, Matthew Woitaszek
Support Vector Machines For Image And Electronic Mail Classification, Matthew Woitaszek
Theses
Support Vector Machines (SVMs) have demonstrated accuracy and efficiency in a variety of binary classification applications including indoor/outdoor scene categorization of consumer photographs and distinguishing unsolicited commercial electronic mail from legitimate personal communications. This thesis examines a parallel implementation of the Sequential Minimal Optimization (SMO) method of training SVMs resulting in multiprocessor speedup subject to a decrease in accuracy dependent on the data distribution and number of processors. Subsequently the SVM classification system was applied to the image labeling and e-mail classification problems. A parallel implementation of the image classification system's color histogram, color coherence, and edge histogram feature extractors …

Effectiveness Of Opc For Systems Integration In The Process Control Information Architecture, Philips Zachariah
Theses
A Process is defined as the progression to some particular end or objective through a logical and orderly sequence of events. Various devices (e.g., actuators, limit switches, motors, sensors, etc.) play a significant role in making sure that the process attains its objective (e.g., maintaining the furnace temperature within an acceptable limit). To do these things effectively, manufacturers need to access data from the plant floor or devices and integrate those into their control applications, which maybe one of the "off the shelf tools such as Supervisory Control and Data Acquisition (SCADA), Distributed Control System (DCS), or Programmable Logic Controllers …
