Blow Molded Specialties Internship

Blow Molded Specialties is an extrusion blow molding firm based in Pawtucket, Rhode
Island. Since 1988 BMS has been a leader in custom blow molding for the medical
device, healthcare, and food packaging industries and beyond. One of BMS’ fields of
expertise is in the development and manufacture of bellows; we manufacture
approximately 40, all varying is size, material and specification requirements.
With this being said, the product design team is currently stymied with an engineering
problem related to a large cylindrical bellows, and is seeking a student intern to research
a solution.

This is an excellent opportunity for a student to gain first-hand experience in researching
and identifying a solution to an engineering issue, while working closely with the
engineering team and within the framework of a manufacturing environment.

The company manufactures a cylindrical bellows that collapses like an articulating straw.
The problem bellows is larger in diameter but is intended to function in the same manner,
with controlled articulation. However, the larger bellows does not behave the same way;
it collapses, but not completely and it will not stay collapsed as the smaller one does.
The company has studied the plastic itself and finds no difference between the two sizes
of bellows, leading to the conclusion that the difference has to do with the geometric
configuration of the larger bellows.

The company has access to an optical comparator, as well as drawings and CAD files of
the two bellows.
A student intern will be asked to analyze the control samples and CAD files, do a sample
match of the CAD files and attempt to determine the significant differences between the
two items. The ultimate aim, of course, is to identify the solution to manufacturing the
larger bellows in a manner that permits controlled articulation and maintains the closed
position when desired.

Please submit resume and cover letter to Avril Cook at acook@bmsplastics.com. We
look forward to hearing from you. Feel free to contact us with questions.

Electronics and Photonics Seminar with John Weiner

Division of Engineering
“Electronics and Photonics Seminar”
Extraordinary optical transmission revisited:
how light gets through isolated or periodic arrays of
subwavelength slits and holes (or not)

Prof. John Weiner
Center for Nanoscale Science and Technology (CNST)
National Institute of Standards and Technology (NIST)
Gaithersburg, MD USA

Thursday, May 6th
12:45pm in Barus & Holley 751
(pizza and sodas will be offered)

Abstract: The passage of light through apertures much smaller than the
wavelength of the light has proved to be a surprisingly subtle phenomenon.
This talk describes how modern developments in nanofabrication, coherent
light sources and numerical vector field simulations have led to the upending
of early predictions from scalar diffraction theory and classical
electrodynamics. Optical response of real materials to incident coherent
radiation at petahertz frequencies leads to unexpected consequences for
transmission (and extinction) of light through subwavelength aperture arrays.

Biosketch: John Weiner is a CNST Visiting Fellow in the Nanofabrication Research
Group. He is Professeur Èmèrite from the Université Paul Sabatier in Toulouse, France.
John received a Ph.D. from the University of Chicago in Chemical Physics. Following
postdoctoral studies and a lectureship at Yale, he joined the faculty at Dartmouth College.
Later, John spent a year as visiting professor at the Laboratoire des Collisions Atomiques
et Moléculaires at Orsay, France, returning to the US to join the faculty at the University
of Maryland, where he investigated atomic collisions at submillikelvin temperatures
achieved by optical cooling techniques. After two decades at Maryland, John returned to
France, where he became interested in light localization by plasmonic structures. At the
CNST, he is working with Henri Lezec on the design, fabrication, and characterization of
nanoscale optical resonator arrays.

Lucy. H. Spelman, DVM: The Canary in the Kitchen: Why Animal Health Matters. Join us for a lecture by veterinarian and visiting Assistant Professor Dr. Lucy Spelman on why animal health matters, followed by a discussion about the many connections between human and animal health. Bring your own examples of the canary in the kitchen! http://picasaweb.google.com/Science.Resource.Center/DropBox?authkey=Gv1sRgCImR-N-_28nU7gE#5467052292985077026

Lucy, a Brown graduate ('85), is currently Visiting Assistant Professor in the Department of Psychology. She has worked as a zoo veterinarian, zoo director, media consultant, and wildlife veterinarian. She is co-author of a collection of stories written by zoo and wildlife vets about their patients called, "The Rhino with Glue-on Shoes." She has also held one of the most specialized jobs in the animal world, that of gorilla doctor. For nearly three years, Lucy lived in central Africa, trekking up and down the mountains of Rwanda, Uganda, and the Democratic Republic of Congo to provide lifesaving care for the endangered mountain gorilla. As field manager for the Mountain Gorilla Veterinary Project, she also helped to expand its one-health program. This novel approach to conservation is based on the concept that the health of one species impacts another. Thus the health of the gorillas is intricately tied to the health of the rangers who protect them, the tourists who visit them, the farmers who live near their park-as well as livestock and other animals. Fresh from this experience, she returned to Brown last fall and taught a senior seminar on primate behavior. Her current course, a first-year seminar called, "Animals As Indicators of Human Health," serves as the framework for this lecture. Lucy begins by offering a series of examples that illustrate the many connections between animal and human health. For instance, overheating Teflon cookware will kill a canary; perhaps it's not as safe for people as we think. Ocean warming causes coral to expel it symbiotic algae; unless the temperature returns to normal, the corals bleach and die, and the entire aquatic food chain is disrupted, including the fisheries millions of people rely on for food. Next she invites the audience to share their own examples, as well as discuss solutions. The good news is that if we're willing to invest in the science behind these problems, we can solve them. The bad news is that we're running out of time.

Joint Materials/Solid Mechanics Seminar Series with Prof. Gui-Rong Liu

BROWN UNIVERSITY
Joint Materials/Solid Mechanics Seminar Series

“Computational methods for certified solutions, adaptive analysis, real-time computation, and inverse analysis of engineering systems”

Friday, April 30, 2010 4:00-5:00 pm B&H Room 751

Prof. Gui-Rong Liu
Deputy Head of Mechanical Engineering
National University of Singapore

Abstract:

Rationale: Engineering systems become more and more sophisticated. Computer modelling for such systems is a must for optimal design, healthy monitoring, NDE, existing strength assessments, and service life prediction. The necessary requirements for an effective computational method have now become stability, convergence, automation, solution certification, adaptation, and real-time computation.
Theory: This talk introduces first the basic theory for a unified formulation of a wide class of compatible and incompatible methods based on FEM and meshfree settings. Important properties and inequalities for G spaces are proven, leading to the so-called weakened weak (W2) formulation that guarantees stable and convergent solutions. We then present some possible W2 models that meet all these challenges: 1) linear conformability ensuring the stability and convergence; 2) softening effects leading to certified solutions and real-time computational models; 3) insensitivity to the quality of mesh allowing effective uses of triangular/tetrahedral meshes best suited for automatic adaptive analyses.
Applications: A large number of benchmarking examples and practical examples will be presented to examine the theory and various numerical models, including material behavior at various extreme situations, dynamic behavior and interactions of red blood cells, inverse identification of material properties and cracks in engineering structural systems, and integrity assessment of dental implant systems via inverse analysis with real-time computation.

IBM semiconductor facility in Essex Junction, Vermont hiring supplemental manufacturing employees

I did want to pass this on for any engineering students at Brown who may be looking for summer work experience. The IBM semiconductor facility in Essex Junction Vermont where I work is looking to hire supplemental manufacturing employees. It may be of some interest to anyone interested in getting some experience in the industry. I personally did this for 2 summers while attending Brown and did help me land my first job after graduation. I know we usually hire local college students to help during the summer vacation season. Students would need to find summer housing, but Burlington is a college town and there are generally many summer sublet opportunities.

Any official openings would be posted at www.ibm.com. The possible summer only positions would be listed as production operators (search with keyword Essex and job area Manufacturing). There are a couple of official co-op/intern positions open in our division as well as some entry level positions listed in our division.

I'd be happy to talk to interested students, although I will say up front that my influence on helping them successfully get hired is likely extremely limited.

You can have them contact me via email (shelden@alumni.brown.edu).

Bacteria in Shear Flow
I present a combined experimental and theoretical analysis of a bacterium exposed to a shear flow. I start by addressing the role of chirality in shear, motivated by the helical shape of some bacterial species (e.g. spirochetes) and of the flagella of all motile bacteria. While non-chiral objects at low Reynolds numbers faithfully follow streamlines, our model based on Resistive Force Theory predicts that the coupling of chirality and shear results in a lift force, which induces a drift perpendicular to the shear plane. We verified this prediction experimentally by exposing spirochetes to a plane parabolic flow in a microfluidic channel and tracking their lateral position by videomicroscopy. This method can be used to separate microscale chiral objects of opposite handedness when shear is larger than rotational Brownian diffusion, providing hope for a straightforward approach for the separation of chiral molecules, of considerable interest in the food and pharmaceutical industries. By tracking individual bacteria in microchannels, we find that shear alters bacterial swimming patterns and in particular reduces their ability to move across streamlines. This results from the bacteria undergoing Jeffery orbits, which bias cell orientation in the direction of the flow and hamper cross-streamline swimming. This can in turn hinder chemotaxis and thus have a significant negative effect on bacteria foraging. Finally, a separate set of experiments shows that bacteria do not alter their swimming behavior in response to shear: nature has apparently not deemed it worthwhile to develop a shear sensor at the micrometer scale.

Granular Aggregates with Capillary Interactions We consider assembly of identical spherical particles (of diameter about 3 mm) floating on the surface of a viscous liquid. Interface deformation and gravity create attractive interactions between particles, leading to capillary aggregation. Firstly, features of this phenomena are experimentally investigated for a small number of particles to understand self-organization of floating spheres. Then for a large number of particles, density is homogeneously increased. Dense aggregates are formed and we investigate structure of such a cohesive granular medium as a function of area fraction. Using Voronoi tesselation, heterogeneity is characterized. Moreover significant short range order is found, by computing pair correlation function and orientational order parameter. This two-dimensional example demonstrates that structure of an athermal system of attractive particles contrasts strongly with the cohesionless case. When density is increased, heterogeneity decreases and steric effects become more important compared to attraction of particles. Finally jamming transition is reached, inducing the buckling of the aggregate.

“Scale and Time Dependent Mechanics of Polymeric Nanofibers”

BROWN UNIVERSITY
Joint Materials/Solid Mechanics Seminar Series

“Scale and Time Dependent Mechanics of Polymeric Nanofibers”

Prof. Ioannis Chasiotis
Department of Aerospace Engineering
University of Illinois at Urbana-Champaign

Abstract:

The mechanical response of polymeric nanostructures as a function of size and strain rate is largely unexplored. This seminar will elaborate on the mechanical behavior of electrospun polymeric nanofibers at strain rates 10-4 - 200 s-1 as a function of their diameter and fabrication conditions. The experiments were conducted via MEMS tools in conjunction with digital image correlation motion tracking, which allowed for high resolution measurements in force and nanofiber extension. The advantage of this method lies with the ability to carry out nanoscale experiments in ambient conditions, contrary to commonly followed practices that require imaging with electron microscopy. The elastic modulus and the tensile strength of nanofibers with diameters between 200-800 nm varied by a factor of seven with fibers in the range of 200-300 nm resulting in the highest property values. Thinner fibers that demonstrated the highest mechanical strengths were characterized by molecular alignment which was confirmed by Fourier transform infrared spectroscopy. Most mechanical properties varied monotonically in the aforementioned range of strain rates, while they were a strong function of the nanofiber diameters and the necking instabilities occurring during the tensile experiments. These results supported the optimization of the fabrication method of electrospinning in order to produce amorphous polymeric nanofibers with true ultimate tensile strength as high as 900 MPa and ductility exceeding 200% at most applied strain rates.

We're a team of Brown CS students and alumns (we've also graduated from Apple and Google) building an awesome startup right here, in Providence. Our team is pretty small and we're looking for some serious talent to help us out. What better way to find talent than by creating a fun challenge?
We have a really good barcode scanner for the iPhone 3GS but we want to extend it to the older model iPhones which have a fixed-focus camera.
Be the first one to write a decoder for UPC/EAN barcodes that can decode blurry pictures of barcodes taken with a first or second generation iPhone (3G), and we’ll write your name on a $2,000 check.
You can use any language you want (Matlab, C, C++, Obj-C preferred), and any Computer Vision library, as long as we can include it in a commercial program and it’s available for C/C++/Obj-C.
You can work in teams and cooperate.
The decoder’s success rate must be of at least 85% and must run in real time (i.e.optimizable to decode a barcode in less than 0.2 seconds)
Send us an email if you are participating, so we can update you with news. challenge@dedoware.com
You have until April 26th, 2010, but you should keep us posted on your progress.Visit http://www.dedoware.com/challenge for more details

MoSAIc REU at Iowa State University

The MoSAIc REU at Iowa State University will provide participants with a ten-week research experience in the area of Microscale Sensing Actuation and Imaging. Students will pursue fundamental investigations related to design and manufacturing of microscale sensors, actuators and smart materials as well as development of state-of-the-art imaging and diagnostic systems. Examples include flexible linkages, magneto-restrictive materials, solar cell architectures, nanomechanical sensors for biological agents, switchable surface assemblies and high spatiotemporal resolution 4-D imaging sensors. The research experiences will be complemented by cohort experiences including a suite of short courses, professional development and extracurricular activities. A unique component of the REU site will be a workshop on ethical issues pertaining to engineering research. Students can walk away from their REU experience where they evolved from a dependent status to a relatively independent status with life-long learning skills that will impact their contributions to society.

Applications are due by April 23, 2010

“Phase-field crystal study of compositional domain formation on surfaces”

BROWN UNIVERSITY
Joint Materials/Solid Mechanics Seminar Series

“Phase-field crystal study of compositional domain formation on surfaces”

Prof. Mikko P. Haataja
Department of Mechanical and Aerospace Engineering
Princeton University

Abstract:

When deposited on a surface, bulk-immiscible binary alloys often display interesting compositional domain formation phenomena at the atomic scale, driven by the lattice mismatch between the substrate atoms and the alloy constituents. Control of such nanoscale features may offer a means to engineer surfaces with tunable chemical and mechanical properties. In this work, we study the structure and dynamics of such domains using the so-called phase-field crystal (PFC) method. In the limit of purely elastic deformations of the adlayer, the model predicts the formation of compositional nanoscale domains for a 1:1 mixture, in agreement with experiments and previous simulations. We further examine the interplay between misfit dislocation formation and compositional patterning for a wide range of alloy compositions.

Elizabeth Schibuk:
“After writing my Science and Society thesis on undergraduate science education reform, I decided to give science education a try. Since graduating in May 2008, I've been teaching chemistry, physics, and sustainable design at a small charter high school in Pawtucket RI. My background in Science and Society has informed my teaching practice as I've worked to develop interdisciplinary units in my classroom. Earlier this year my chemistry students spent five weeks investigating the science and the politics of nuclear warfare and nuclear energy. My students got the chance to video conference with an active nuclear submariner as well as with a former Naval nuclear reactor operator before writing position papers on a nuclear-chemistry related "issue" of their choice. In a different vein, my physics class recently began studying the history of astronomy, and has been studying the historical interface between science and religion as they prepare to perform a mock trial of Galileo. Though these projects certainly deviate from any standard high school curriculum, I find student engagement increases when students can study science in the context of some social or historical "problem." I very much enjoy teaching science and recognize the ways that my Brown education inspired me and prepared me for this career.”
