Falvey Scholars 2022: Mai Khuc ’22 COE

Mai Khuc The Falvey Scholars Program is an annual program established by Falvey Library to recognize outstanding undergraduate research. Now in its 20th year, the program is a collective initiative of the Library and the Center for Research and Fellowships. The recipients of this award are selected from a pool of candidates nominated by Villanova faculty and reviewed by Library staff and faculty.

This year, eight students received awards, their work reflecting the breadth and depth of undergraduate research at the University as well as the support the Library, its resources and staff, provide student-scholars.

This blog is the last of seven installments, which will introduce our scholars and cover their research in their own words. Look for additional coverage of the Falvey Scholars in the fall issue of Mosaic.

Congratulations to all of our Falvey Scholars, past and present!

Describe your research in your own words.
Data centers consume approximately 2% of all U.S. electricity, so efficiency improvements can yield large financial and environmental benefits.

I started out by learning about data centers, their operations, and their energy usage. I have never had a chance to learn about air conditioning systems in my engineering class before, thus Falvey Library was a great resource for me to get started.

After modeling the heat recovery system in Aspen Plus simulation software, I once again relied on the Library to learn about financial terminology, such as capital cost as well as payback period and how to calculate them. I also looked up different case studies to compare my analysis with other researchers’ work. After getting my capital cost and payback period, I used different sustainability metrics to evaluate these systems’ performance from an environmental perspective.

How did Falvey’s resources and databases impact your research?
The resources from Falvey Library have helped me tremendously throughout my career at Villanova, especially over this project where I tried to estimate the capital cost of a data center energy recovery system.

The online library has a wide variety of both physical and electronic books, journal articles, and conference papers for me to learn more about data centers, their energy consumption, as well as different heat recovery options. My project also has environmental and business aspects, such as sustainability metrics and capital cost estimation, thus many large databases in different fields that Falvey has have allowed me to access the top-quality papers in multiple disciplines.

How did the Library’s staff impact your research and academic experience?
Those resources could not have been used to their full potential if not thanks to the most friendly and supportive librarians that I met. I was fortunate enough to meet Alfred Fry, Science and Engineering Librarian, during my first semester at Villanova when he came to two of my classes to teach us how to most effectively utilize Falvey’s resources.

Those tips that Alfred has taught us have been extremely helpful for me, especially for this research since I was looking for a very niche field. I have also had the opportunity to work with both Alfred and Linda Hauck, Business Librarian, personally, and while our meeting was not directly related to this research, I have learned a lot from their guidance during these sessions and applied it to my project, specifically their advice on how to properly use engineering and economics resources.

What’s next for you?
I am now working as an Energy Engineer in the Albany, N.Y., office of Ramboll, an engineering consulting firm based in Denmark. While I won’t be working directly with data centers, it is still working to use energy most efficiently.


Engineering Historica: The Final Report on the Engineering and Construction of the Quebec Bridge

To His Excellency, Victor Christian William, Duke of Devonshire, Marquis of  Hartington, Earl of Devonshire, Earl of Burlington, Baron Cavendish of Hardwicke, Baron Cavendish of Keighley, K.G., P.C., G.C.M.G., etc,. etc, Governor-General of Canada,

May it Please Your Excellency:

The undersigned have the honour to lay before Your Excellency the Final Report of the Board of Engineers on the Design and Construction of the Quebec Bridge.

Respectfully Submitted,

J.D. Reid,

Minister of Railways and Canals

Our digital library collection grows day by day, as volunteers and staff at the Falvey Memorial Library here at Villanova University continue to scan different works from both our own collection as well as collections generously loaned from other institutions.  Because Villanova is a Catholic university, much of this material is of related interest, i.e. our collection includes scanned Catholic manuscripts, works from Augustinian scholars, collections related to Irish history, etc.  Of course, not every item in our collection comes from this area, so I’ve decided to highlight one item from our collection today with more of an engineering-historical bent.

Published in 1919, and donated to Villanova in 1944, the digital library currently has posted two volumes containing the final report from the board of engineers on the design and construction of the Quebec Bridge.  With its abundance of information, figures and stats on the bridge, this material may be of interest to civil and structural engineers on its own merit; however, what makes this a more interesting read is that the Quebec Bridge itself is famous above and beyond other bridges for three reasons: the first is that, at 987 meters, the bridge is the longest cantilever (i.e. non-suspension) bridge in the world; the second and third reasons are related – the bridge is also famous for collapsing not once, but twice during construction, the first occurrence in 1907, the second in 1916.

The Quebec Bridge @1919

Fortunately for the travelers and commuters among us, bridge collapses, though not unheard of, are a rare occurrence – and collapsing while still under construction rarer still.  To collapse twice, however, is exceptionally rare.  Therein, the story of the construction of this particular bridge is a fascinating tale – the initial warning signs of the first impending bridge collapse were ignored, and eventually when pleas from on-site engineers to halt construction on the bridge were finally heeded, the message did not arrive to the construction site in time before disaster struck.   The resulting collapse cost the lives of 75 bridge builders.  When construction of the bridge began a few years later, disaster struck again when the central span of the bridge was being raised into position – the span fell during the raising, killing an additional 13 workers [1].

Raising the Central Span

This particular report covers the time period of the second bridge building, including the time period when the central portion fell into the river (the central portion was re-raised and the bridge eventually completed, leading to this report). While the later sections of this report are very “engineer dense”, with drawings, figures and tables on the exact structure of the bridge (load tolerance of the materials used, etc.), most users will find the General Narrative, starting at page 13 of the book, the most interesting portion of the read.  It recounts the issues with the first bridge and its collapse, what was changed in the new bridge and why, as well as a running narrative of the construction of the new span (the fall of the central span is covered on page 32).  Included in this read are some interesting historical references (note the reference to the Lusitania on page 18 as the current ship with the tallest mast, and references to the Carnegie Steel Co. and Bethlehem Steel on page 25, amongst others).

The complete scan of this report is available through the Villanova University Digital Library.  Volume I can be found here and Volume II here.
