North Lake Ave Bridge Design

North Lake Ave is a road located in Worcester, MA that has been suffering from erosion for many years. Conceptual plans have been made to create a linear park and convert this road into a one-way. Options have been considered to address the erosion and collapse of the road. The design for a retaining wall and bridge will be compared based on safety, economic, constructability, environmental, societal and sustainability criteria. The design for the bridge includes the superstructure, substructure, and foundation, in compliance with AASHTO LRFD Bridge Design Specifications

Marquette Interchange Phase I Final Report

This report provides details on the design, installation and monitoring of a pavement instrumentation system for the analysis of load-induced stresses and strains within a perpetual HMA pavement system. The HMA pavement was constructed as part of an urban highway improvement project in the City of Milwaukee, Wisconsin. The outer wheel path of the outside lane was instrumented with asphalt strain sensors, base and subgrade pressure sensors, subgrade moisture and temperature sensors, HMA layer temperature sensors, traffic wander strips and a weigh in motion system. Environmental sensors for air temperature, wind speed and solar radiation are also included. The system captures the pavement response from each axle loading and transmits the data through a wireless link to a resident database at Marquette University. The collected data will be used to estimate the fatigue life of the perpetual HMA pavement and to modify, as necessary, pavement design procedures used within the State of Wisconsin

WPI - Pedestrian Bridge Study

This project explored alternative structural solutions for a pedestrian bridge to connect the field atop of the new Parking Garage to the alleyway behind Harrington Auditorium at the Worcester Polytechnic Institute Campus. Four basic bridge types, each consisting of steel or concrete, were initially considered. Two alternatives, a steel truss bridge and a steel arch bridge, were designed in detail. A Building Information Model was generated to visualize the two alternatives. The supporting bridge structure using cast-in-place reinforced concrete for both cases was also designed

Highway Bridge Redesign

The goal of this MQP was to analyze different possible replacement strategies for a specific highway bridge to design the most easily implementable and efficient replacement. Design of the bridge elements was completed in accordance with the AASHTO LRFD Bridge Specification and was aided by the use of software. The final presentation included a structural design of the selected superstructure and substructure with accompanying construction and traffic planning, as well as a cost estimate of direct and indirect costs

Measures of reconfigurability and its key characteristics in intelligent manufacturing systems

\In recent years, the fields of reconfigurable manufacturing systems, holonic manufacturing systems, and multi-agent systems have made technological advances to support the ready reconfiguration of automated manufacturing systems. While these technological advances have demonstrated robust operation and been qualitatively successful in achieving reconfigurability, limited effort has been devoted to the measurement of reconfigurability in the resultant systems. Hence, it is not clear (1) to which degree these designs have achieved their intended level of reconfigurability, (2) which systems are indeed quantitatively more reconfigurable and (3) how these designs may overcome their design limitations to achieve greater reconfigurability in subsequent design iterations. Recently, a reconfigurability measurement process based upon axiomatic design knowledge base and the design structure matrix has been developed. Together, they provide quantitative measures of reconfiguration potential and ease. This paper now builds upon these works to provide a set of composite reconfigurability measures. Among these are measures for the key characteristics of reconfigurability: integrability, convertibility, and customization, which have driven the qualitative and intuitive design of these technological advances. These measures are then demonstrated on an illustrative example followed by a discussion of how they adhere to requirements for reconfigurability measurement in automated and intelligent manufacturing systems

Energy efficient wireless sensor network protocols for monitoring and prognostics of large scale systems

In this work, energy-efficient protocols for wireless sensor networks (WSN) with applications to prognostics are investigated. Both analytical methods and verification are shown for the proposed methods via either hardware experiments or simulation. This work is presented in five papers. Energy-efficiency methods for WSN include distributed algorithms for i) optimal routing, ii) adaptive scheduling, iii) adaptive transmission power and data-rate control --Abstract, page iv
