Analysis Of Methods For Assigning Capacity In A Transportation Planning Network, Yogesh Kandaswamy Dheenadayalu
Analysis Of Methods For Assigning Capacity In A Transportation Planning Network, Yogesh Kandaswamy Dheenadayalu
LSU Master's Theses
The objective of the research was to analyze the current practice of assigning capacity values to links of a network and to determine how capacity can be assigned more accurately without greatly increasing time, effort and costs. Currently in most planning networks, the link capacities are assigned based on the number of lanes and a gross facility and area type considerations (LSU, 1997). This practice might have affected the results of travel demand modeling performed using the network. To test this hypothesis, the current practice was compared to the practice of assigning capacities link-by-link using the Highway Capacity Manual (HCM) …
Movement Along The Baton Rouge Fault, Araya Eshetu Kebede
Movement Along The Baton Rouge Fault, Araya Eshetu Kebede
LSU Master's Theses
The Baton Rouge fault is one of two faults (the other being Denham Spring-Scotlandville fault) that traverse the city of Baton Rouge and has long been thought to be active. Structural damages to buildings, streets and sidewalks near the fault have previously been attributed to movement of the fault. Although the presence of the fault has been known for nearly 60 years, previous investigations have failed to determine its rate of movement. This study was aimed at determining the rate of modern movement along the Baton Rouge fault. Using a precise geodetic leveling technique, the current elevations of NGS (National …
Ternary And Quaternary Logic To Binary Bit Conversion Cmos Integrated Circuit Design Using Multiple Input Floating Gate Mosfets, Harish N. Venkata
Ternary And Quaternary Logic To Binary Bit Conversion Cmos Integrated Circuit Design Using Multiple Input Floating Gate Mosfets, Harish N. Venkata
LSU Master's Theses
Multiple-input floating gate MOSFETs and floating gate potential diagrams have been used for conversion of ternary-valued input and quaternary-valued input into corresponding binary-valued output in CMOS integrated circuit design environment. The method is demonstrated through the design of a circuit for conversion of ternary inputs 00 to -1-1 (decimal 0 to -4) and 00 to 11 (decimal 0 to +4) into the corresponding binary bits and for conversion of quaternary inputs (decimal 0 to 3) into the corresponding binary bits (binary 00 to 11) in a standard 1.5 mm digital CMOS technology. The physical design of the circuits is simulated …
Multiple-Access Interference Suppression In Cdma Wireless Systems, Jianqiang He
Multiple-Access Interference Suppression In Cdma Wireless Systems, Jianqiang He
LSU Master's Theses
This thesis presents techniques that suppress the multiple access interference (MAI) in CDMA wireless systems. MAI is the main factor that influences the communication quality and the capacity in CDMA wireless systems. Hence the suppression of MAI is essential to the performance of a CDMA wireless system. For conventional CDMA systems where matched filters are used as receivers, the only MAI suppression method available is the power control, which allocates each user in the system an appropriate transmitter power level such that the transmitter power is minimized to decrease the MAI, while at the same time each user maintains a …
Electrodeposition Of Niw Alloys Into Deep Recesses, Lakshmikanth Namburi
Electrodeposition Of Niw Alloys Into Deep Recesses, Lakshmikanth Namburi
LSU Master's Theses
Pulse electrodeposition has been investigated as a general technique for the electrodeposition of nickel-tungsten alloys in deep recesses for MEMS. Ni-W exhibits an induced codeposition mechanism, where the Ni reaction rate enhances the codeposition of W. Electrodeposition of this alloy has been achieved into recesses of 500 micron deep. The challenges that have been encountered are those related to gas evolving side reactions, local pH rises, diffusional limitations of the soluble species and long times required for filling the recesses. Electrodeposition on cylinder electrodes at different rotation rates was also carried out in order to obtain data on composition of …
Simulation Study And Instability Of Adaptive Control, Zhongshan Wu
Simulation Study And Instability Of Adaptive Control, Zhongshan Wu
LSU Master's Theses
The Minimum-degree Pole Placement algorithm for Self-tuning Regulator design and the Recursive Least-square method and the projection algorithm for plant estimation are studied first in this thesis. Simulation studies for the estimator and controller algorithms are mainly undertaken after describing how to use MATLAB S-function in detail. Not only do Simulation experiments illustrates how and how well the MDPP and RLS algorithms work, but also show how to write and debug MATLAB codes for S-function programs. The robustness of the adaptive control system is intensively discussed subsequently. By using an estimator resistant to the noise contamination, the adaptive control system …
Dynamic Scheduling, Allocation, And Compaction Scheme For Real-Time Tasks On Fpgas, Shobharani Tatineni
Dynamic Scheduling, Allocation, And Compaction Scheme For Real-Time Tasks On Fpgas, Shobharani Tatineni
LSU Master's Theses
Run-time reconfiguration (RTR) is a method of computing on reconfigurable logic, typically FPGAs, changing hardware configurations from phase to phase of a computation at run-time. Recent research has expanded from a focus on a single application at a time to encompass a view of the reconfigurable logic as a resource shared among multiple applications or users. In real-time system design, task deadlines play an important role. Real-time multi-tasking systems not only need to support sharing of the resources in space, but also need to guarantee execution of the tasks. At the operating system level, sharing logic gates, wires, and I/O …
Polyurethane Foam Based Packing Media For Biofilters Removing Volatile Organic Compounds From Contaminated Air, Felipe A. Martinez
Polyurethane Foam Based Packing Media For Biofilters Removing Volatile Organic Compounds From Contaminated Air, Felipe A. Martinez
LSU Master's Theses
In recent years, biofiltration technology has gained acceptance worldwide as an economical and reliable air pollution control technology for treating gases contaminated by low concentrations of biodegradable volatile organic compounds (VOCs). Important applications include control of odors generated by wastewater treatment plants and control of VOC emissions from industrial sources. Although there have been many successful applications, several operational problems have been reported in the literature. These include difficulty in control over bed moisture content, high head loss caused by excessive biomass production, and inability to maintain removal efficiency during transient periods of high concentration loading. Use of a superior …
