Adaptive Motion Pooling And Diffusion For Optical Flow, Naga Venkata Kartheek Medathati, Pierre Kornprobst, Guillaume Masson, Manuela Chessa, Fabio Solari

MODVIS Workshop

We study the impact of local context of an image (contrast and 2D structure) on spatial motion integration by MT neurons. To do so, we revisited the seminal work by Heeger and Simoncelli (HS) [4] using spatio-temporal filters to estimate optical flow from V1-MT feedforward interactions. However, the HS model has difficulties to deal with several problems encountered in real scenes (e.g., blank wall problem and motion discontinuities). Here, we propose to extend the HS model with adaptive processing by focussing on the role of local context indicative of the local velocity estimates reliability. We set a network structure representative …

A Space-Variant Model For Motion Interpretation Across The Visual Field, Guido Maiello, Manuela Chessa, Peter J. Bex, Fabio Solari

MODVIS Workshop

We implement a neural model for the estimation of the focus of radial motion (FRM) at different retinal locations and we assess the model by comparing its results with respect to the precision with which human observers can estimate the FRM in naturalistic, moving dead leaves stimuli. The proposed neural model describes the deep hierarchy of the first stages of the dorsal visual pathway [Solari et al., 2014]. Such a model is space-variant, since it takes into account the retino-cortical transformation of the primate visual system through log-polar mapping that produces a cortical representation of the visual signal to the …

Electrospinning Of Polycaprolactone Core-Shell Nanofibers With Anti-Cancer Drug, Sakib Iqbal, Mujibur Khan, Saheem Absar, Andrew Diamanduros, Samuel Chambers

GS4 Student Scholars Symposium

Encapsulation of a model anti-cancer drug, 5-Fluorouracul (5-FU) into biocompatible core-shell nanofibers of polycaprolactone (PCL) nanofibers was fabricated using a coaxial electrospinning process. Our work aims to solve these issues using a novel method of fabrication of fibers featuring confinement of drugs within a biodegradable core-shell structure, thereby permitting sustained release of drugs to specific sites of treatment, such as tissues affected with tumor cells. The coaxial electrospinning was performed using a sheath polymer solution consisting of a 14 wt% PCL solution and a 5 wt% solution of 5-FU as the core solution. Dimethylformamide (DMF) was used as the solvent …

PSU High School Innovation Challenge

We have noticed that there is an increasing number of homeless in our community. People who are homeless have a more difficult time getting jobs, making it harder to for them to get back on their feet.

Homeless is defined as a person without a stable place to live, in risk of being homeless. Homeless under Federal status, is defined as fleeing/attempting to escape domestic violence. Examples of homelessness include couch surfing, sleeping in shelters, and living in a car.

Our proposal was to build homeless shelters out of shipping containers.

People with cell phones often take it for granted how much knowledge is at their fingertips. Many people without cell phones don’t have easy instant access to the information that others do, leaving them in the dark. This kiosk would aid the homeless community, tourists, and people whose cell phones are not working. This is often overlooked by middle and upper class people, who have cell phones ingrained as a way of life.

People that do not have access to information miss out on opportunities to better their situation. There are many resources such as educational, medical, and professional tools. …

Portland is known as Bike City U.S.A for its promotion of a eco friendly method of transportation and support of biking infrastructure. Although our city has this progressive reputation, there is a negative aspect of a bike-loving city that has not received attention. The Oregon Household Activity survey in 2011 states that “about 29 percent of adults in Multnomah, Clackamas and Washington counties own a bike”. As more people has decided to commute with bikes, theft has increased dramatically. According to the Portland Police Bureau, “Portland thieves last year took more than 2,100 bikes worth well over $1 million combined”. …

PSU High School Innovation Challenge

A huge problem with current modernized and non modernized cities is the amount of trash being thrown away. There is a tremendous amount of recyclable material that is being thrown away with non recyclable waste into massive landfills. Even though we can not physically see the trash that we throw away on the street, it must still go somewhere. Some of that waste is toxic, other waste is made of non decomposable material. These massive waste disposal sites hurt animals, damage soil, and harm the health people living nearby.

In 2007, Americans threw out about 570 billion pounds of municipal …

Pavement Underdrain To Achieve Longer Life Pavement Structure, Tommy E. Nantung

Purdue Road School

Drainage as the key to pavement performance has been suggested since the early design of modern pavement structures. In fact, the three parameters for pavement performance are drainage, drainage and drainage. Drainage is so important to the performance of pavement that many state DOTs mandate a pavement underdrain system for routes with medium to high truck traffic. In the current evolution of pavement underdrain design, the speed of water removal from the soil foundation is the key issue. In a recent field investigation, some pavement sections with an underdrain system are not immune to pavement structural deterioration. It was determined …
