Pesticide Demand Among Hybrid Vegetable And Cereal Seed Producers In Bangladesh: A Simultaneous Equation Analysis, S Rahman, Mz Hossain

School of Geography, Earth and Environmental Sciences

Demand for pesticides, inorganic and organic fertilizers were jointly estimated using survey data from a randomly selected 81 BRAC ‘contract hybrid vegetables and cereal seed growers’ in northwestern Bangladesh applying a simultaneous equation framework. Pesticide cost accounts for 6.9% of the gross value of output in hybrid seeds of vegetables and 3.2% in cereals. About 87% of farmers used pesticides at least once with mean number of application of 4.4 times. Twenty-seven brands of pesticides were used including a substantial number of banned pesticides. Price elasticity of demand for pesticides, fertilizers and biofertilizers were estimated at –0.83, –0.21 and –1.13, …

From Robotic Toil To Symbolic Theft: Grounding Transfer From Entry-Level To Higher-Level Categories1, A Cangelosi, A Greco, S Harnad

School of Engineering, Computing and Mathematics

Neural network models of categorical perception (compression of within-category similarity and dilation of between-category differences) are applied to the symbol-grounding problem (of how to connect symbols with meanings) by connecting analogue sensorimotor projections to arbitrary symbolic representations via learned category-invariance detectors in a hybrid symbolic/non-symbolic system. Our nets are trained to categorize and name 50 × 50 pixel images (e.g. circles, ellipses, squares and rectangles) projected on to the receptive field of a 7 × 7 retina. They first learn to do prototype matching and then entry-level naming for the four kinds of stimuli, grounding their names directly in the …

Intermodal Transit System Coordination With Dynamic Vehicle Dispatching, Md. Shoaib Chowdhury

Dissertations

In most urban areas where transit demand is spread widely, passengers may be served by an intermodal transit system, consisting of a rail transit line (or a bus rapid transit route) and a numbers of feeder routes connecting at different transfer stations. In such a system, passengers may need one or more transfers to complete their journey. Therefore, scheduling vehicles operating in the system with special attention to reduce transfer time can contribute significantly service quality improvements. In this study two models, one for coordination of a general intermodal. transit system and another for dynamic dispatching of vehicles on coordinated …

Genetically Evolved Dynamic Control For Quadruped Walking, Giorgio Grasso

Dissertations

The aim of this dissertation is to show that dynamic control of quadruped locomotion is achievable through the use of genetically evolved central pattern generators. This strategy is tested both in simulation and on a walking robot. The design of the walker has been chosen to be statically unstable, so that during motion less than three supporting feet may be in contact with the ground.

The control strategy adopted is capable of propelling the artificial walker at a forward locomotion speed of ~1.5 Km/h on rugged terrain and provides for stability of motion. The learning of walking, based on simulated …

Endotoxin Removal From Protein Solutions By Immobilized Metal Ion Affinity Chromatography, Yun Kang

Dissertations

In the biotechnology/pharmaceutical industry, the removal of endotoxins from final protein product has always been a challenge. A novel method for endotoxin removal from protein solutions, immobilized metal (ion) affinity chromatography (IMAC) has been developed in this study. Fe³⁺ was charged to a chelating gel that contains iminodiacetic acid (IDA). The IDA- Fe³⁺ IMAC column was exploited to remove endotoxin from protein solutions. This method involves the adsorption of the endotoxin on IMAC column. More than 99% endotoxin is removed and protein yield is higher than 90%. IDA-Fe³⁺ IMAC has proved to be an economical and efficient …

Investigation Of The Baroreflex Of The Rat : Steady State And Dynamic Features, Xiaorui Tang

Dissertations

The baroreflex is one of the most important feedback systems in the body to maintain blood pressure variation within the homeostatic range. In this dissertation, the important features of the carotid and aortic baroreflexes have been extensively investigated on ventilated, central nervous system intact, neuromuscular blocked (NMB) rats using different control system and signal processing tools. Studies have demonstrated that sinoaortic denervation (SAD) caused substantial increases in the blood pressure variability. Comparing the pre- and post-SAD blood pressure spectra, there was a significant increase of power in the very low frequency region (0.00195 -0.2 Hz), and a significant decrease of …

Applications Of Agent Architectures To Decision Support In Distributed Simulation And Training Systems, Plamen V. Petrov

Dissertations

This work develops the approach and presents the results of a new model for applying intelligent agents to complex distributed interactive simulation for command and control. In the framework of tactical command, control communications, computers and intelligence (C₄I), software agents provide a novel approach for efficient decision support and distributed interactive mission training. An agent-based architecture for decision support is designed, implemented and is applied in a distributed interactive simulation to significantly enhance the command and control training during simulated exercises. The architecture is based on monitoring, evaluation, and advice agents, which cooperate to provide alternatives to the …

Airflow Characteristics Of Commonly Used Temperature Radiation Shields*, X. Lin, Kenneth G. Hubbard, George E. Meyer

School of Natural Resources: Faculty Publications

The air temperature radiation shield is a key component in air temperature measurement in weather station networks; however, it is widely recognized that significant errors in the measured air temperature exist due to insufficient airflow past the air temperature sensor housed inside the shield. During the last several decades, the U.S. National Weather Service has employed a number of different shields in air temperature measurements. This paper focuses on the airflow characteristics inside air temperature shields including the Maximum–Minimum Temperature System (MMTS), the Gill shields, and the Cotton Region Shelter (CRS).

Average airspeed profiles and airflow efficiency inside the shields …

Simulation And Modeling Of Magnetically-Assisted Impaction Coating (Maic) Process For Dry Particle Coating, Bodhisattwa Chaudhuri

Dissertations

The objective of proposed research is to model, and understand the processes happening at multiple length and time scales in magnetically assisted impaction coating process. The smallest length scale is of the order of the molecular size and is important because during collisions the molecules rearrange themselves to form a semi-permanent bond between the core and secondary particles, which is studied by using the results of direct numerical integration of the governing Newton's equations. The effect of parameters such as size, orientation and relative velocity of particles on the collision mechanics is quantified. The largest length scale which is the …

Comparing The Effectiveness Of Instructor-Led Training To Stand-Alone Web-Based Training : A Case Study, Robert P. Myre

Theses

Web-based Training (WBT) is still a relatively new technology, and the full extent of WBT functionality has yet to be realized. Most of corporate America recognizes the necessity of a well-trained workforce; however, instructor-led training is often difficult to implement due to a variety of logistical issues. These issue, include cost constraints, location issues, and limited resources.

WBT has been touted in recent years as a viable alternative to traditional, instructor-led training. However, the effectiveness of WBT versus instructor-led training has been questioned by its many critics. This case study tested the effectiveness of a stand-alone web-based training program and …
