Cost-Benefit Analysis Of Error Reduction For Complex Systems, Robert A. Mcdonald
Cost-Benefit Analysis Of Error Reduction For Complex Systems, Robert A. Mcdonald
Aerospace Engineering
The cost-benefit tradeoff of analysis fidelity in complex systems analysis has been posed as an optimization problem providing quantitative guidance for investment in improving analysis. A nonlinear constrained optimizer to solve this problem has been integrated into an error tradeoff environment providing an intuitive tool for the decision maker to consider investment in fidelity at the same time as design decisions are considered. An example demonstrates the efficacy of the improved interface to enable fidelity improvement investment decisions.

A Modification To The Group Delay And Simulated Annealing Technique For Characterization Of Peripheral Nerve Fiber Size Distributions For Non-Deterministic Sampled Data, Robert B. Szlavik
A Modification To The Group Delay And Simulated Annealing Technique For Characterization Of Peripheral Nerve Fiber Size Distributions For Non-Deterministic Sampled Data, Robert B. Szlavik
Biomedical Engineering
The ability to determine the characteristics of peripheral nerve fiber size distributions would provide additional information to clinicians for the diagnosis of specific pathologies of the peripheral nervous system. Investigation of these conditions, using electro-diagnostic techniques, is advantageous in the sense that such techniques tend to be minimally invasive yet provide valuable diagnostic information. One of the principal electro-diagnostic tools available to the clinician is the nerve conduction velocity test. While the peripheral nerve conduction velocity test can provide useful information to the clinician regarding the viability of the nerve under study, it is a single parameter test that yields …
A Novel Approach For Analyzing Severe Crash Patterns On Multilane Highways, Anurag Pande, Mohamed Abdel-Aty
A Novel Approach For Analyzing Severe Crash Patterns On Multilane Highways, Anurag Pande, Mohamed Abdel-Aty
Civil and Environmental Engineering
This study presents a novel approach for analysis of patterns in severe crashes that occur on mid-block segments of multilane highways with partially limited access. A within stratum matched crash vs. non-crash classification approach is adopted towards that end. Under this approach crashes serve as units of analysis and it does not require aggregation of crash data over arterial segments of arbitrary lengths. Also, the proposed approach does not use information on non-severe crashes and hence is not affected by under-reporting of the minor crashes. Random samples of time, day of week, and location (i.e., milepost) combinations were collected for …
Variability Within Irrigated Fields, Charles M. Burt, Byron Clark
Variability Within Irrigated Fields, Charles M. Burt, Byron Clark
BioResource and Agricultural Engineering
In agricultural production and research, it is common to represent fields as uniform areas. For example, fertilizers, soil amendments, and other inputs have traditionally been applied uniformly (or as uniformly as possible) based on estimated needs for the field as a whole (or as an “average”).
Of course, it is also recognized that fields are not truly uniform with respect to soil characteristics, uniformity of applied water, pest pressures, fertility needs, crop growth and yield, and other characteristics. With the emergence and refinement of variable rate application technology, many growers now attempt to maximize returns by “prescribing” variable amounts of …
Traffic Signal Control With Swarm Intelligence, David Renfrew, Xiao-Hua Yu
Traffic Signal Control With Swarm Intelligence, David Renfrew, Xiao-Hua Yu
Electrical Engineering
Traffic signal control is an effective way to regulate traffic flow to avoid conflict and reduce congestion. The ACO (Ant Colony Optimization) algorithm is an optimization technique based on swarm intelligence. This research investigates the application of ACO to traffic signal control problem. The decentralized, collective, stochastic, and self-organization properties of this algorithm fit well with the nature of traffic networks. Computer simulation results show that this method outperforms the conventional fully actuated control, especially under the condition of high traffic demand.
Electrocardiogram (Ecg) Signal Modeling And Noise Reduction Using Wavelet Neural Networks, Suranai Poungponsri, Xiao-Hua Yu
Electrocardiogram (Ecg) Signal Modeling And Noise Reduction Using Wavelet Neural Networks, Suranai Poungponsri, Xiao-Hua Yu
Electrical Engineering
Electrocardiogram (ECG) signal has been widely used in cardiac pathology to detect heart disease. In this paper, wavelet neural network (WNN) is studied for ECG signal modeling and noise reduction. WNN combines the multi-resolution nature of wavelets and the adaptive learning ability of artificial neural networks, and is trained by a hybrid algorithm that includes the adaptive diversity learning particle swarm optimization (ADLPSO) and the gradient descent optimization. Computer simulation results demonstrate this proposed approach can successfully model the ECG signal and remove high-frequency noise.

Electrical Engineering
Frequency dependent I/Q imbalance in real I/Q filter pairs compensation may be performed using a simple compensation module, placed in the receiver/transmitter chain, with a gain adjustment coefficient and a delay adjustment coefficient. The gain adjustment coefficient may be determined by amplitude measurements conducted at a selected frequency near the center of the band-pass region of the filters. The delay adjustment coefficient may be determined by phase measurements conducted at a selected frequency near the edge of the band-pass region of the filters. Statistical analysis may be used to determine types of real filters that are better suited for the …

Reinvestigation Of Liquefaction And Nonliquefaction Case Histories From The 1976 Tangshan Earthquake, Robb E.S. Moss, Robert Kayen, Liyuan Tong, Songyu Liu, Guojun Cai, Jiaer Wu
Civil and Environmental Engineering
A field investigation was carried out to retest liquefaction and nonliquefaction sites from the 1976 Tangshan earthquake in the People's Republic of China (PRC). These sites were carefully investigated in 1978/1979 using standard penetration test (SPT) and cone penetration test (CPT) equipment; however the CPT measurements are obsolete because of the now nonstandard cone that was used at the time. In 2007 a modern cone was mobilized to retest 18 select sites that are particularly valuable because they experienced intense ground shaking, have high fines content, and are classified as nonliquefaction sites. Of the sites reinvestigated and carefully processed, 13 …
Using Conditional Inference Forests To Identify The Factors Affecting Crash Severity On Arterial Corridors, Abhishek Das, Mohamed Abdel-Aty, Anurag Pande
Using Conditional Inference Forests To Identify The Factors Affecting Crash Severity On Arterial Corridors, Abhishek Das, Mohamed Abdel-Aty, Anurag Pande
Civil and Environmental Engineering
Introduction
The study aims at identifying traffic/highway design/driver-vehicle information significantly related with fatal/severe crashes on urban arterials for different crash types. Since the data used in this study are observational (i.e., collected outside the purview of a designed experiment), an information discovery approach is adopted for this study.
Method
Random Forests, which are ensembles of individual trees grown by CART (Classification and Regression Tree) algorithm, are applied in numerous applications for this purpose. Specifically, conditional inference forests have been implemented. In each tree of the conditional inference forest, splits are based on how good the association is. Chi-square test statistics …

Electrical Engineering
This paper presents a parallelized architecture for hardware acceleration of multi-view face detection. In our architecture, the multi-view face detection system generates rotated image windows and their integral image windows for each classifier which perform parallel classification operations to detect non-upright (rotated) and non-frontal (profile) faces in the images. We use the training data from OpenCV to detect the frontal and profile faces based on the Viola and Jones algorithm. The proposed architecture for multi-view face detection has been designed using Verilog HDL and implemented in a Xilinx Virtex-5 FPGA. Its performance has been measured and compared with a Jones' …

Bit Error Rate, Power And Area Analysis Of Multiple Fpga Implementations Of Underwater Fsk, Ying Li, Bridget Benson, Ryan Kastner, Xing Zhang
Electrical Engineering
There has been an increasing interest in creating short-range, low data-rate underwater wireless sensor networks for scientific marine exploration and monitoring. However, the lack of an inexpensive, low-power, underwater acoustic modem is preventing the proliferation of these sensor networks. Thus, we are building an underwater acoustic modem that considers cost and power at every level, from the analog electronics, to the modulation scheme, to the hardware platform. In this paper, we use reconfigurable devices to explore the design space of our modulation scheme – Frequency Shift Keying (FSK) – to select an implementation that provides the lowest power and area …

Materials Engineering
Obliquely deposited thin films of ternary Ag–Ge–S glasses are characterized in this work. Thin films are fabricated in a vacuum thermal evaporator at different evaporation angles and examined by Raman spectroscopy. The Raman mode frequency of GeS4 corner-sharing (CS) structure of the as-deposited films display a red-shift as a function of Ag content due to reduced global connectivity, and therefore decreased network stress. Film thickness of normally deposited thin films is significantly less when compared against obliquely deposited ones. Sulfur-ring (S8) modes are observed in thin films but not in corresponding bulk material. Thermal annealing of thin …
