Serving Eastern Massachusetts
Thomas “Thom” Davidson will discuss his work on the Nacala Dam Rehabilitation project. The Government of the Republic of Mozambique (GOM) has received a grant from the Millennium Challenge Corporation (MCC), an innovative United States established foreign assistance program designed to reduce poverty by promoting sustainable economic growth. The MCC operates on the principle that aid is most effective in countries that promote good governance, economic freedom and investments in people. The GOM, through MCA (Millennium Challenge Account-Mozambique, a public institution created by the GOM) and its National Directorate of Water (DNA-GOH), intends to use a portion of the proceeds of this grant, to carry out feasibility studies relating to the rehabilitation and augmentation of the Nacala Dam and Reservoir. The U. S. Army Corps of Engineers, New England District is providing technical engineering services to support MCC for all deliverables associated with the rehabilitation and augmentation of the dam and reservoir.
The Nacala Dam is located on the Muecula River approximately 30 kilometers south west of Nacala and serves as the primary water source for the town of Nacala which is situated approximately 200 kilometers north east of Nampula City. It was designed and constructed from 1968 to 1975. The current water supply system is inadequate for projected development for the town of Nacala and its deep water port. In 1982 the dam embankment was overtopped for 10 consecutive hours due to the non operation of the spillway gates. In1983 the wash away area was reinstated and a layer of stone pitching was placed on the downstream face of the embankment as a protective measure against the possibility of future overtopping. Further repairs were undertaken in 1995 and 2002 during road improvement projects. A pre-feasibility study into the possibility of rehabilitating and raising the dam embankment was performed by Michael Baker Jr. Inc. (Baker) in 2006. In 2009, the Contractor (Jeffares and Greene), performed a geotechnical investigation program to assess the dam and reservoir for rehabilitation and augmentation.
Thom Davidson graduated in 1991 from DePauw University with a Bachelor of Arts in Geology, and in 2004 he received his Master of Science degree in Geology & Geophysics from Boston College. He began his career in the private sector where he worked with the Massachusetts Water Resources Authority, as a Geologist on the Metrowest Tunnel Project. Over the next eight years he worked on various environmental and large civil infrastructure projects which included Defense Environmental Restoration Projects on Formerly Used Defense Sites (DERP-FUDS); the Fall River Combined Sewer Overflow (CSO) Abatement Tunnel Project; the Braintree/Weymouth Tunnel Project; the Iroquois Gas Pipeline Phase II Geotechnical Investigation Project, Northport/Bronx, New York and the South Boston Piers Transit Way Project for the Massachusetts Bay Transportation Authority Silver Line Maintenance Facility.
Thom joined the U.S. Army Corps of Engineers, New England District in May 2004. He is the Engineering Technical Lead on the Massachusetts Military Reservation (MMR) Groundwater Restoration Project in Bourne, Massachusetts. He has also been part of the U.S. Army Corps of Engineers Dam Safety Inspection program since and is currently involved in assessing foundation conditions at dam rehabilitation projects within New England District.

The lecture will begin with a brief consideration of geological change on geological time scales as the driving force of all of evolution, including and specifically human evolution in Africa beginning around 15 million years ago. With this backdrop we consider the emergence of homo sapiens approximately 200,000 years ago, followed by human migration out of Africa. To appreciate this part of the story we have to discuss DNA, mutations, evolutionary selection, chromosomal haplotypes, and mitochondrial genetics, as well as the specifics and peculiarities of human reproduction. By the end of the lecture Prof. Wangh will discuss the rise of civilization, about 10,000 years ago, and will talk about population growth, the genetics underlying human subpopulations (races), the human genome project, and genomic medicine of the future based on personalized SNP chips.

The oceans provide an important source of food and other natural resources and are a critical component of the global climate. The harsh environment faced in underwater exploration and study presents many engineering challenges because of the extreme pressures and temperatures encountered and the high corrosivity and electromagnetic absorption of sea water. Our mission is to develop advanced autonomous underwater vehicle (AUV) technology and promote its use and benefits in the study and utilization of the oceans. By incorporating onboard sensors, computers, power supply, and pre-programmed missions, AUVs have several advantages over manned submersibles and remotely operated vehicles (ROV), resulting in reduced cost of construction and operation. Ultimately, these reduced costs will facilitate access to and expand our understanding of the ocean environment.
We have developed an AUV, the Odyssey IV, that is a multi-purpose vehicle system for a wide variety of applications. The AUV is capable of both cruising and hovering maneuvers, is rated for 6000 meter depth dives, and can operate continuously for over 8 hours on a single battery charge. Recently, the vehicle has performed imaging surveys of the ocean floor in Massachusetts Bay and Stellwagen Bank to study damage to offshore habitat caused by invasive species. The AUV is being prepared for upcoming deep water missions to discover new colonies of rare cold-water coral species. Also, the Odyssey IV is used to develop technology for autonomous inspection of ultra-deep manmade structures with navigation by machine vision for use in offshore oil and gas production operations.
The Reef Explorer vehicle is a lightweight, one-man-deployable, hybrid AUV-ROV that is capable of dives up to 25 meters. The vehicle is tele-operated with manual and supervisory control. Video and telemetry from the Reef Explorer is transmitted wirelessly and over the internet in real time to a pilot located anywhere with internet access. The vehicle is routinely deployed in Kaneohe Bay, HI and remotely piloted from Cambridge, MA. The applications for the Reef Explorer include habitat studies, ship hull inspection, and classroom-based virtual field trips to coral reefs.
Finally, as part of our educational programs to foster oceanography and engineering instruction in primary schools, we have developed the Sea Perch, a small, low cost ROV. The Sea Perch is constructed mostly of household materials and can be built in approximately 12 hours using a simple set of hand tools. Students benefit from and enjoy the hands-on experience of constructing and deploying the vehicles. The Sea Perch design can be easily adapted to carry sensor payloads and accessories that allow incorporation into curricula for physical science, biology, chemistry, and other courses.
Seth
Newburg has been a research engineer in the MIT AUV Lab since March
2009. His interests focused on underwater robotics technology ten
years earlier while an undergraduate at MIT when he founded Project
ORCA, a student team dedicated to designing AUVs for the International
Autonomous Underwater Vehicles Competition sponsored by AUVSI and ONR.
The experience of implementing sonar systems for AUVs led him to pursue
research in auditory physiology, including that of whales and dolphins,
for his doctorate in biomedical engineering at Boston University.
As part of the AUV Lab's engineering team, Newburg draws on his
multi-disciplinary background in carrying out his primary responsibility
for the design and integration of robust sensor systems for the Odyssey
IV autonomous underwater vehicle project. The meeting will be held
at the Lincoln Lab Auditorium at 4:00 PM. Refreshments will be served at

The
key to defending an IT system or network is to understand the threats it
faces. How does the threat operate, what tools and techniques does
it use, how does it achieve access to the target system, how technically
sophisticated is it, how well financed is it, what are the intentions of
the threat, and who, if anyone, is backing them? The purpose of
this talk is to convince you that all cyber threats are not equal.
They vary greatly in intentions, technical sophistication, access
methods, financing and tools and techniques. In order to simplify
things, we have created 5 different levels of cyber threats:
Cyber Vandalism – Use widespread non-targeted attacks over the Internet designed to cause disruption of services. May have loose affiliation using social networking sites for prestige and to establish bragging rights. Can also employ more targeted attacks to deface specific web sites. Intent is to cause as much widespread disruption as possible or to embarrass the victim.
Cyber Crime – Adversaries motivated by greed or ideology. The intent is to steal money, identities, services or intellectual property and in some cases to commit blackmail associated with corruption of data or denial of service. Perpetrator attempts to be more covert than the cyber vandal.
Cyber Surveillance – Broad based general surveillance conducted via internet-based attacks designed to gain large amounts of information held by the target. Could be information pertaining to national security, financial data, commercial products, or intellectual property. Could also be conducted for general infrastructure surveillance purposes or to plant seeds for later corruption of data or denial of service. These operations are generally better financed and more technically sophisticated than the Level 1 and 2 attacks.
Cyber Espionage – Very specifically targeted espionage using a number of highly sophisticated approaches. Can be Internet based or penetrations taking advantage of insider access. Remote attacks can also be enabled by physical attacks either via supply chain intercept or by using a co-opted or even unwitting insider. Intent is to remain highly covert in penetration, presence and exfiltration. May leave behind tools that can be activated on demand for future use in corrupting data or denial of service.
Cyber Warfare – Will use multiple approaches to degrade or destroy an opponent’s use of its information infrastructure. Non-state actors may develop more limited versions of these approaches in the future as well. The techniques can vary across the entire threat spectrum of those described and extend to physical or electronic disruption of communication equipment and paths, processing sites, data storage sites, command centers, and importantly to the homeland critical infrastructure.
