Autonomous navigation algorithms for indoor mobile robots
In many autonomous mobile robotic applications, the capability of finding a good path is of primary importance, especially for the places which are cluttered by random obstacles that may appear on the robot's path.
Effects of nutrients conditions and solids retention time (SRT) on performance and membrane fouling of aerobic membrane bioreactors (MBRs)
This thesis investigated the effect of chemical oxygen demand (COD) to nitrogen ratio (COD:N) in feed on the biological performance of aerobic membrane bioreactor (MBR). Meanwhile, the effects of nutrients condition (COD:N ...
Utilization of coal biomass fly ash in the control and treatment of acid mine drainage
This study investigated the feasibility of using coal/biomass fly ash (CBFA) blended with various percentages of mine tailings, bentonite, and glacial till soil to control and treat acid mine drainage (AMD). Applications ...
Adsorption and microflotation studies with pure minerals and an arylhydroxamic acid collector
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
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
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
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
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
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
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, ...
