Forgetting And The Value Of Social Information, Benjamin James Abts

Theses

Information is everywhere in nature, however it can be deceitful or incorrect, so not all information should be used. Foraging pollinators utilize variable and ephemeral resources so learning about patch quality and nectar replenishment rates are essential to success and survival. However, remembering information after it is no longer relevant is not advantageous. It has been theorized that a pollinator’s memory should reflect their environment. Bumblebees are known to use both personal information (information gathered through trial and error) and social information (information gained through observations of or interactions with other animals or their products) in foraging decisions; however, it …

Memory Emphasizing Digital Camera, Jae Ho Seo

Theses

The thesis is focused on how users can realize the value of personal memories when they use cameras.

The design of a camera has barely changed over the hundreds of years of its history. In the current market, most companies emphasize functionalities, such as better quality images, faster processors, and safer storage. However, the basic rectangular form factor, the round lens, and the layout of control knobs and buttons are essentially the same amongst many different companies. Similar to the auto design, the camera design has changed minimally in its outer shape with slightly advanced inner components.

It is important …

Predicting Choices In Bumblebees (Bombus Impatiens): Learning Rules And The Two-Armed Bandit, Isabel Lucia Rojas-Ferrer

Theses

Animals must make estimates about possible resources in order to choose the resource which will save them time and energy while conferring high energetic content. In order to make the most optimal decision, foragers must use various parameters to come up with an accurate estimate for each possible alternative. Learning rules allow us the possibility of analyzing which parameters animals may be using in order to make the best decision. We use compare known learning rules (i.e. Linear Operator Rule, Relative Payoff Sum Rule, Perfect Memory) and experimental data extracted from bumblebees (Bombus impatiens) subjected to a two armed bandit …

The Home, Memory, And Materialism Explored Through Landscape, Kelly Wilton

Theses

Moving from Arizona two years ago meant editing down my possessions to fit in the back of a pickup truck that my best friend, two cats, and I shared for three days. I have been moving on average about once a year since I was fourteen. This nomadic lifestyle meant constantly having to get rid of things that felt unimportant and insignificant. Certain things, however, have survived the moves. Throughout my nomadic lifestyle, the bedroom became a curated space for possessions put on display, showcasing the importing things I own. In my travels, landscape and house became equally important in …

A Scalable Flash-Based Hardware Architecture For The Hierarchical Temporal Memory Spatial Pooler, Lennard G. Streat

Theses

Hierarchical temporal memory (HTM) is a biomimetic machine learning algorithm focused upon modeling the structural and algorithmic properties of the neocortex. It is comprised of two components, realizing pattern recognition of spatial and temporal data, respectively. HTM research has gained momentum in recent years, leading to both hardware and software exploration of its algorithmic formulation. Previous work on HTM has centered on addressing performance concerns; however, the memory-bound operation of HTM presents significant challenges to scalability.

In this work, a scalable flash-based storage processor unit, Flash-HTM (FHTM), is presented along with a detailed analysis of its potential scalability. FHTM leverages …

Anticonvulsant And Procognitive Properties Of Novel Histamine H3 Receptor Antagonists In Male Adult Rats, Ali Kassem Saad

Theses

To determine the potential of histamine H3 receptor (H3R) ligands as new antiepileptic and procognitive drugs, aromatic ether derivatives (1-12) belonging to the nonimidazole class of ligands, with high in-vitro binding affinity at human H3R, were tested for their in-vivo anticonvulsive activity in maximal electroshock (MES)-, pentylenetetrazole (PTZ)-, and strychnine (STR)-induced seizure models in male adult rats having phenytoin (PHT) and valproic acid (VPA) as the reference antiepileptic drugs, pitolisant (PIT) as the standard H3R antagonist/inverse agonist, and donepezil (DOZ) as a reference procognitive drug. Among the H3R ligands (1-12) tested in the current project, H3R …
