Adsorption and microflotation studies with pure minerals and an arylhydroxamic acid collector
(2009)
A study was conducted to understand the adsorption of N-hydrocinnamoyl-N-phenylhydroxyl-amine (HCNPHA) on the surfaces of various pure minerals: sphalerite, pyrite, galena, chalcopyrite and quartz. HCNPHA is a member of ...
Image-based visual servoing of a VTOL UAV
(2009)
Unmanned Aerial Vehicles (UAVs) are an area of significant research activity these days because of their use in dull, dangerous, and dirty tasks. Lack of human pilot paves the way for advanced and more sophisticated control ...
Thermophilic and mesophilic aerobic biological treatment of wastewater
(2010)
To achieve closed cycle operation and subsequent reuse of treated effluent, individual streams of pulp and paper mill effluents are being evaluated for their suitability for in-mill treatment. This thesis includes two ...
Effects of freezing on UV inactivation of waterbourne microorganisms
(2009)
In northern communities where source water may be frozen for parts of the year or wastewater is treated using freezing technology, the efficiency of UV inactivation may be affected. This research was carried out to investigate ...
Modeling and identification of an axially-moving cantilever beam
(2002)
An axially-moving cantilever beam is used to study identification o f time-varying
systems. A circuitry for DC motor current control and sensor conditioning is built. The
circuitry meets the design requirement of controlling ...
Modeling and control of various styles of paper machine headboxes
(2003)
In this thesis non-linear mathematical models of a typical paper machine approach system
with three different styles of headboxes are presented. The non-linear models include the
dynamics of the fan pump, DC motor, ...
Vibration suppression in a traversing mass-cantilever beam system
(2003)
A cantilever beam carrying a traversing spring-mass system is modeled. Applications of the system include robot traversing on space trusses, loads moving along stacker cranes carrying moving loads in a large warehouse, ...
Modeling and analysis of limit cycles in buck converters under PI control
(2005)
A zero order hold equivalent discrete-time model of the buck converter for computing its
large signal frequency-response is developed and experimentally verified. It is shown that
with a dc bias and a sinusoidal variation ...
Investigation into the use of ELG for stand alone power system frequency control
(2006)
The use of ELG for stand alone power system frequency control is investigated in this
thesis. Characteristics of a stand alone power system with PCR-ELG are presented.
Dynamic simulation of the system is developed using ...
Radio resource allocation in OFDMA system
(2006)
In this thesis, orthogonal frequency division multiple access (OFDMA) system is considered.
Assuming perfect knowledge of instantaneous channel conditions for all users, we propose resource
allocation algorithms to ...
