Analysis Of Per Capita Expenditures Of Suburbanizing Communities In Maine, New England Environmental Finance Center
Analysis Of Per Capita Expenditures Of Suburbanizing Communities In Maine, New England Environmental Finance Center
Economics and Finance
This study analyzes per capita expenditure trends among selected fast-growing Maine towns from 1970-2004. The ten communities studied are termed as “suburbanizing” towns. This term is used to describe towns that over the past 30-40 years have been in the process of transition from rural to suburban – in terms of their population and housing densities, their forms of government, and the services they provide, as well as other characteristics.1 Such towns are of particular interest because they have been absorbing a healthy percentage of the state’s population growth during this time period, often at the expense of Maine’s service …
Revised Asce Specification For The Design Of Cold-Formed Stainless Steel Structural Members, Shin Hua Lin, Wei Wen Yu, Theodore V. Galambos, Edward Wang
Revised Asce Specification For The Design Of Cold-Formed Stainless Steel Structural Members, Shin Hua Lin, Wei Wen Yu, Theodore V. Galambos, Edward Wang
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Since the publication of the first edition of the AISI specification for the design of light gage cold-formed stainless steel structural members in 1968 [Specification for the design of light gage cold-formed stainless steel structural members. 1968 ed. American Iron and Steel Institute (AISI); 1968], cold-formed stainless-steel members have been increasingly used in building construction and other structural applications due to their superior corrosion resistance, ease of maintenance, pleasing appearance, and high strength. in 1990, the first ASCE standard, ANSI/ASCE-8-90 [Specification for the design of cold-formed stainless steel structural members (ANSI/ASCE 8-90). American Society of Civil Engineers (ASCE); 1991], was …
Damage Localization In Ambient Vibration By Constructing Proportional Flexibility Matrix, Zhongdong Duan, Guirong Yan, Jinping Ou, B. F. Spencer
Damage Localization In Ambient Vibration By Constructing Proportional Flexibility Matrix, Zhongdong Duan, Guirong Yan, Jinping Ou, B. F. Spencer
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Damage Localization Approaches based on Changes of Flexibilities Constitute an Important Technique for Damage Detection. However, the Unavailability of Flexibility Matrix with Output-Only Data Makes Flexibility-Based Approaches Not Really Applicable in the Very Important Cases of Ambient Vibrations. an Algorithm is Presented to Construct a Proportional Flexibility Matrix (PFM) from a Set of Arbitrarily Scaled Tested Modal Shapes and Modal Frequencies. the Constructed PFM is Just within a Scalar Multiplier to the Real Flexibility Matrix, and the Scalar Multiplier is Theoretically the First Modal Mass, Which is Undetermined Before the Mode is Properly Scaled. Instead of Real Flexibilities, the PFMs …
Thermal Efficiency Characteristics Of Indirect Evaporative Cooling Systems, Ben Costelloe, Donal Finn
Thermal Efficiency Characteristics Of Indirect Evaporative Cooling Systems, Ben Costelloe, Donal Finn
Conference Papers
Recent developments in enhancing heat transfer in cooling towers, together with the success of chilled ceilings, have prompted a review of the evaporative cooling technique. in temperate maritime climates. The thermal efficiency of such systems is a key parameter, as a measure of the degree to which the system has succeeded in exploiting the cooling potential of the ambient air. This paper presents the results of experimental research into the thermal efficiency of a water-side open indirect evaporative cooling test rig designed to achieve low (1-4 K) approach conditions. Secondary efficiencies in the range 0.24-0.76 have been achieved.
Lessons Learned From Failures Of The Building Envelope In Windstorms, Joseph E. Minor
Lessons Learned From Failures Of The Building Envelope In Windstorms, Joseph E. Minor
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Lessons learned from failures of the building envelope in windstorms are encapsulated in three principal findings. the building envelope is crucial to the performance of buildings in windstorms. Windborne debris is decisive in shaping the performance of the building envelope. Design attention should be given to postimpact behavior of building-envelope systems. Reviews of damage documentation, insurance records, and computer simulations of building failures establish the importance of the building envelope to satisfactory building performance. These reviews also establish the decisive role of windborne debris in causing damage. the imperative for considering the postimpact behavior of building envelope systems is discussed, …

Individual Certification As An Engineering Manager?, Rafael Landaeta, Kawintorn Pothanun, William Peterson
Engineering Management & Systems Engineering Faculty Publications
Several of the discipline specific professional societies are offering or planning to offer certification of individuals as engineering managers. Does this have implications for Engineering Management programs at universities? Other stakeholders (faculty, students, employers, and graduates of engineering management programs) are impacted by certification as well. This paper attempts to look at the issue from several points of view. This paper is intended to provoke a dialog on the topic.

Or-05-6-4: Relating Human Productivity And Annoyance To Indoor Noise Criteria Systems: A Low Frequency Analysis, Erica Eileen Bowden, Lily M. Wang
Durham School of Architectural Engineering and Construction: Faculty Publications
A number of indoor noise criteria systems are used to quantify the background noise in a built environment, including Noise Criteria (NC), Balanced Noise Criteria (NCB), Room Criteria (RC), Room Criteria Mark II (RC Mark II), A-weighted Equivalent Sound Pressure Level (LAeq), and others. An on-going debate exists in the acoustical community over which criterion is the most appropriate to use in the variety of ambient noise situations encountered. In an effort to quantitatively support the use of individual criterion, this project subjectively correlates these various criteria with human task performance and perception. Eleven subjects participated in a …

Mechanical Damping System For Structures, Jay A. Puckett, Patrick S. Mcmanus, Homer R. Hamilton Iii
Durham School of Architectural Engineering and Construction: Faculty Publications
A mechanical damping system for a structure is provided. The mechanical damping system comprises a tubular impact frame secured to the structure. A support frame is secured to the structure with the support frame spaced from the impact frame. An elongated member is provided having a first end and a second end. The first end is secured within the support frame and the second end is free from connection and extends into the impact frame. At least one impact mass is secured to the second end of the elongated member, the impact mass movable within and contactable with the impact …
