Improving The Truck Driver Job, Kerry Melton

Operations Management Presentations

Freight transportation has increased dramatically over the last 35 years as freight and shipment demand have expanded resulting in truck driver and equipment capacity issues and infrastructure problems. Freight transport tonnage in the U.S. is predominately truck transportation consisting of more than 70% of all freight distribution with a 25% growth expectation over the next 5 years. Within the trucking industry, over-the-road (OTR) truckload transportation consists of 50% of all truck tonnage shipped. Due to high OTR truckload demand, OTR driver capacity issues have plagued the truckload industry for years. Additionally, high OTR driver turnover and poor driver job retention …

Effective Room-Temperature Ammonia-Sensitive Composite Sensor Based On Graphene Nanoplates And Pani, Zongbiao Ye, Yan Chen, Bohao Liu, Yuanjie Su, Zhi Chen, Huiling Tai, Yadong Jiang

Electrical and Computer Engineering Faculty Publications

The graphene nanoplate (GN)-polyaniline (PANI) composite was developed via in-situ polymerization method and simultaneously assembled on interdigital electrodes (IDEs) at low temperature for ammonia (NH₃) detection. The assembled composite sensor showed excellent sensing performance toward different concentrations of NH₃, 1.5 of response value and 123 s/204 s for the response/recovery time to 15 ppm NH₃. Meanwhile, an interesting supersaturation phenomenon was observed at high concentration of NH₃. A reasonable speculation was proposed for this special sensing behavior and the mechanism for enhanced sensing properties was also analyzed.

Correlated Network Of Networks Enhances Robustness Against Catastrophic Failures, Byungjoon Min, Muhua Zheng

Publications and Research

Networks in nature rarely function in isolation but instead interact with one another with a form of a network of networks (NoN). A network of networks with interdependency between distinct networks contains instability of abrupt collapse related to the global rule of activation. As a remedy of the collapse instability, here we investigate a model of correlated NoN. We find that the collapse instability can be removed when hubs provide the majority of interconnections and interconnections are convergent between hubs. Thus, our study identifies a stable structure of correlated NoN against catastrophic failures. Our result further suggests a plausible way …

Radiology Faculty Publications

Intravesical Bacillus Calmette–Guerin (BCG) immunotherapy is a proven, effective treatment for intermediate- and high-risk non-muscle-invasive bladder cancer. Minor side effects are common and expected but systemic effects can occur in < 5% of treated patients. We present a rare case of a 49-year-old male that presented with fever and chills after 3 weeks of intravesical BCG therapy post transurethral resection of bladder tumor. New renal lesions were present on contrast-enhanced computed tomography scan which was histologically proven to be necrotizing renal granulomatosis.

Stepping Responses To Treadmill Perturbations Vary With Severity Of Motor Deficits In Human Sci, Virginia W. T. Chu, T. George Hornby, Brian D. Schmit

Biomedical Engineering Faculty Research and Publications

In this study, we investigated the responses to tread perturbations during human stepping on a treadmill. Our approach was to test the effects of perturbations to a single leg using a split-belt treadmill in healthy participants and in participants with varying severity of spinal cord injury (SCI). We recruited 11 people with incomplete SCI and 5 noninjured participants. As participants walked on an instrumented treadmill, the belt on one side was stopped or accelerated briefly during mid to late stance. A majority of participants initiated an unnecessary swing when the treadmill was stopped in mid stance, although the likelihood of …

Investigations On Frp-Concrete Bond, Mostfa Al Azzawi

USF Tampa Graduate Theses and Dissertations

This dissertation presents findings from three separate investigations, a laboratory study and two field studies that evaluated the durability of the Fiber Reinforced Polymer (FRP)-concrete bond. The laboratory study explored the role of porosity on CFRP-concrete bond following immersion in warm water. Two disparate field studies measured residual bond after 20 years outdoor exposure of FRP repairs of full-size masonry walls and after 12 years for partially submerged piles supporting the Friendship Trail Bridge, Tampa Bay.

The ACI 440 code requires the same surface preparation for all externally bonded FRP concrete repairs. This disregards the role of porosity that is …

A Route Less Traveled: Principals’ Perceptions Of Alternative Licensed Cte Teachers, Scott R. Bartholomew, Emma P. Bullock, Louis S. Nadelson

Faculty Publications

The shortage of teachers prepared to teach career and technical education (CTE) courses, or willing to work in certain locations (e.g. inner city, rural), has motivated the desire to explore solutions such as alternative routes to teacher licensure (ARL). Most ARL programs bypass colleges of education and provide a different approach to preparing individuals to teach, leaving many to wonder about the quality and knowledge of these teachers. Specific areas, such as CTE, have seen a large influx of ARL teachers in recent years. We sought to determine school principals’ perceptions of ARL CTE teachers. We found principal support for …
