Simple Apparatus For Producing Single Liquid Drops, Dhiren Panda, D. G. C. Robertson 2017 Missouri University of Science and Technology

Simple Apparatus For Producing Single Liquid Drops, Dhiren Panda, D. G. C. Robertson

D. G. C. Robertson

A simple experimental apparatus has been used to produce individual mercury and sodium amalgam drops in the size range of 0.3-2.5 mm diam. A high resistance to the flow of liquid was provided by a capillary tube. The cross section consisted of a 0.20 mm o.d. tungsten wire placed in a 0.25 mm capillary bore. By this method, flow rates of 1 μl/s and lower were obtained, which enabled the formation of drops as small as 1 mm diam in a time interval of 20 s. The drops were formed at a plastic tip ...

Developing Grounded Goals Through Instant Replay Learning, Lisa Meeden, Douglas S. Blank 2017 Swarthmore College

Developing Grounded Goals Through Instant Replay Learning, Lisa Meeden, Douglas S. Blank

Computer Science Faculty Research and Scholarship

This paper describes and tests a developmental architecture that enables a robot to explore its world, to find and remember interesting states, to associate these states with grounded goal representations, and to generate action sequences so that it can re-visit these states of interest. The model is composed of feed-forward neural networks that learn to make predictions at two levels through a dual mechanism of motor babbling for discovering the interesting goal states and instant replay learning for developing the grounded goal representations. We compare the performance of the model with grounded goal representations versus random goal representations, and find ...


Smooth Muscle Stiffness Sensitivity Is Driven By Soluble And Insoluble Ecm Chemistry, William G. Herrick, Shruti Rattan, Thuy V. Nguyen, Michael S. Grunwald, Christopher W. Barney, Alfred J. Crosby, Shelly Peyton 2017 University of Massachusetts - Amherst

Smooth Muscle Stiffness Sensitivity Is Driven By Soluble And Insoluble Ecm Chemistry, William G. Herrick, Shruti Rattan, Thuy V. Nguyen, Michael S. Grunwald, Christopher W. Barney, Alfred J. Crosby, Shelly Peyton

Shelly Peyton

Smooth muscle cell (SMC) invasion into plaques and subsequent proliferation is a major factor in the progression of atherosclerosis. During disease progression, SMCs experience major changes in their microenvironment, such as what integrin-binding sites are exposed, the portfolio of soluble factors available, and the elasticity and modulus of the surrounding vessel wall. We have developed a hydrogel biomaterial platform to examine the combined effect of these changes on SMC phenotype. We were particularly interested in how the chemical microenvironment affected the ability of SMCs to sense and respond to modulus. To our surprise, we observed that integrin binding and soluble ...


Peg-Phosphorylcholine Hydrogels As Tunable And Versatile Platforms For Mechanobiology, William G. Herrick, Thuy V. Nguyen, Marianne Sleiman, Samantha McRae, Todd Emrick, Shelly Peyton 2017 University of Massachusetts - Amherst

Peg-Phosphorylcholine Hydrogels As Tunable And Versatile Platforms For Mechanobiology, William G. Herrick, Thuy V. Nguyen, Marianne Sleiman, Samantha Mcrae, Todd Emrick, Shelly Peyton

Shelly Peyton

We report here the synthesis of a new class of hydrogels with an extremely wide range of mechanical properties suitable for cell studies. Mechanobiology has emerged as an important field in bioengineering, in part due to the development of synthetic polymer gels and fibrous protein biomaterials to control and quantify how cells sense and respond to mechanical forces in their microenvironment. To address the problem of limited availability of biomaterials, in terms of both mechanical range and optical clarity, we have prepared hydrogels that combine poly(ethylene glycol) (PEG) and phosphorylcholine (PC) zwitterions. Our goal was to create a hydrogel ...

When Big Data Gets Too Big, 2017 Vocational Training Council

When Big Data Gets Too Big

SIGNED: The Magazine of The Hong Kong Design Institute

Computer modelling has long been used as a design tool, and big data is a massive resource on which to build these models. But when the datasets get too big for computers to handle, innovative design solutions are needed. And the urge to play has driven technology forward


Estimating River Discharge Using Multiple-Tide Gauges Distributed Along A Channel, Hamed R. Moftakhari, David A. Jay, Stefan Talke 2017 Portland State University

Estimating River Discharge Using Multiple-Tide Gauges Distributed Along A Channel, Hamed R. Moftakhari, David A. Jay, Stefan Talke

Stefan A. Talke

Reliable estimation of freshwater inflow to the ocean from large tidal rivers is vital for water resources management and climate analyses. Discharge gauging stations are typically located beyond the tidal intrusion reach, such that inputs and losses occurring closer to the ocean are not included. Here, we develop a method of estimating river discharge using multiple gauges and time-dependent tidal statistics determined via wavelet analysis. The Multiple-gauge Tidal Discharge Estimate (MTDE) method is developed using data from the Columbia River and Fraser River estuaries and calibrated against river discharge. Next, we evaluate the general applicability of MTDE by testing an ...

17 How To Start A Career In Architecture, Amy Harker

Amy Harker

If you’re just oozing with creativity and can’t stop yourself from sketching, then you may have considered a career in architecture.

An architect works in all spectrums of design, including creating plans and technical drawings of buildings. They can be found working in so many different settings, whether it’s on large buildings or for a housing estate, they can even be self-employed and focus on house extensions. You never know, you may become a famous architect like Antoni Gaudi who designed La Sagrada Familia, Barcelona’s most famous landmark!


A Look To The Sustainable Draining Systems: Criteria Of Sustainability And Successful Cases, Marian Sabau 2017 Universidad de la Costa

A Look To The Sustainable Draining Systems: Criteria Of Sustainability And Successful Cases, Marian Sabau

Marian Sabau

There have been many studies and research that address sustainable drainage urban systems (SUDS), where factors like costs or the zone where a SUDS is to be installed are determinant, so multicriteria studies are important in decision-making. The development of a multidisciplinary approach could in the future serve as a helping tool to support decision, whose purpose would be to guide users in their choice of the most appropriate solution for managing the collection of rainwater. Another key point is to make use of other strategies to accurately define the most appropriate SUDS for a particular location. Modelling for example ...


The Predictive Link Between Matrix And Metastasis, Lauren E. Barney, Lauren Jansen, S. R. Polio, Sualyneth Galarza, Maureen E. Lynch, Shelly Peyton 2017 University of Massachusetts Amherst

The Predictive Link Between Matrix And Metastasis, Lauren E. Barney, Lauren Jansen, S. R. Polio, Sualyneth Galarza, Maureen E. Lynch, Shelly Peyton

Shelly Peyton

Cancer spread (metastasis) is responsible for 90% of cancer-related fatalities. Informing patient treatment to prevent metastasis, or kill all cancer cells in a patient's body before it becomes metastatic is extremely powerful. However, aggressive treatment for all non-metastatic patients is detrimental, both for quality of life concerns, and the risk of kidney or liver-related toxicity. Knowing when and where a patient has metastatic risk could revolutionize patient treatment and care. In this review, we attempt to summarize the key work of engineers and quantitative biologists in developing strategies and model systems to predict metastasis, with a particular focus on ...


Mechanics Of Intact Bone Marrow, Lauren Jansen, Nathan P. Birch, Jessica D. Schiffman, Alfred J. Crosby, Shelly Peyton 2017 University of Massachusetts Amherst

Mechanics Of Intact Bone Marrow, Lauren Jansen, Nathan P. Birch, Jessica D. Schiffman, Alfred J. Crosby, Shelly Peyton

Shelly Peyton

The current knowledge of bone marrow mechanics is limited to its viscous properties, neglecting the elastic contribution of the extracellular matrix. To get a more complete view of the mechanics of marrow, we characterized intact yellow porcine bone marrow using three different, but complementary techniques: rheology, indentation, and cavitation. Our analysis shows that bone marrow is elastic, and has a large amount of intra- and inter-sample heterogeneity, with an effective Young’s modulus ranging from 0.25-24.7 kPa at physiological temperature. Each testing method was consistent across matched tissue samples, and each provided unique benefits depending on user needs ...


Generalized Fractals For Computer Generated Art: Preliminary Results, Charles F. Babbs 2017 Purdue University

Generalized Fractals For Computer Generated Art: Preliminary Results, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

This paper explores new types of fractals created by iteration of the functions xn+1 = f1(xn, yn) and yn+1 = f2(xn, yn) in a general plane, rather than in the complex plane. Iteration of such functions generates orbits with novel fractal patterns. Especially interesting are N-th order polynomials, raised to a positive or negative integer power, p.

Such functions create novel fractal patterns, including budding, spiked, striped, dragon head, and bat-like forms. The present faculty working paper shows how to create a rich variety of complex and fascinating fractals using this generalized approach, which is accessible to students ...

The Challenges Of Building Intelligent Tutoring Systems For Teams, Desmond Bonner, Stephen B. Gilbert, Michael C. Dorneich, Eliot Winer, Anne M. Sinatra, Anna Slavina, Anastacia MacAllister, Joseph Holub 2017 Iowa State University

The Challenges Of Building Intelligent Tutoring Systems For Teams, Desmond Bonner, Stephen B. Gilbert, Michael C. Dorneich, Eliot Winer, Anne M. Sinatra, Anna Slavina, Anastacia Macallister, Joseph Holub

Anastacia MacAllister

Intelligent Tutoring Systems have been useful for individual instruction and training, but have not been widely created for teams, despite the widespread use of team training and learning in groups. This paper reviews two projects that developed team tutors: the Team Multiple Errands Task (TMET) and the Recon Task developed using the Generalized Intelligent Framework for Tutoring (GIFT). Specifically, this paper 1) analyzes why team tasks have significantly more complexity than an individual task, 2) describes the two team-based platforms for team research, and 3) explores the complexities of team tutor authoring. Results include a recommended process for authoring a ...


Fusing Self-Reported And Sensor Data From Mixed-Reality Training, Trevor Richardson, Stephen B. Gilbert, Joseph Holub, Frederick Thompson, Anastacia MacAllister, Rafael Radkowski, Eliot Winer 2017 Iowa State University

Fusing Self-Reported And Sensor Data From Mixed-Reality Training, Trevor Richardson, Stephen B. Gilbert, Joseph Holub, Frederick Thompson, Anastacia Macallister, Rafael Radkowski, Eliot Winer

Anastacia MacAllister

Military and industrial use of smaller, more accurate sensors are allowing increasing amounts of data to be acquired at diminishing costs during training. Traditional human subject testing often collects qualitative data from participants through self-reported questionnaires. This qualitative information is valuable but often incomplete to assess training outcomes. Quantitative information such as motion tracking data, communication frequency, and heart rate can offer the missing pieces in training outcome assessment. The successful fusion and analysis of qualitative and quantitative information sources is necessary for collaborative, mixed-reality, and augmented-reality training to reach its full potential. The challenge is determining a reliable framework ...

Stephen B. Gilbert

With the movement in education towards collaborative learning, it is becoming more important that learners be able to work together in groups and teams. Intelligent tutoring systems (ITSs) have been used successfully to teach individuals, but so far only a few ITSs have been used for the purpose of training teams. This is due to the difficulty of creating such systems. An ITS for teams must be able to assess complex interactions between team members (team skills) as well as the way they interact with the system itself (task skills). Assessing team skills can be difficult because they contain social ...
