Automated Barrel Cleaner, Brian C. Gumino

Honors Capstones

Numerous industrial companies use 55 and 30 gallon barrels to hold, transport, and dispense liquids and chemicals. Due to this there are many businesses that will reuse their barrels. In order to reuse their barrels, they must clean them to ensure there is no cross contamination from contents that were in the barrel before placing new contents in them. This is normally a time consuming process for most businesses depending on the material that was inside the barrel. With the hefty time relationship related to cleaning barrels most companies either dispose of their barrels, either legally or sometimes illegally, or …

Motivation In Mathematics, Andre J. Richmond

Honors Capstones

I conducted a review of existing mathematics education research on students’ motivation related to mathematics learning. My initial research questions were: “What are the constructs of student motivation as related to mathematics learning?” and “How do they these constructs inform mathematical teaching practice?” The research method that I decided to used was secondary research. I found that motivation can be understood in terms of self-efficacy, cognitive engagement, skill development, achievement motivation, self-regulation, and mindset about mathematics. Students’ unproductive beliefs can undermine their progress in mathematics learning. Motivation is what drives a person to do something. As a future teacher, I …

Looking Into The Crystal Ball: Requirements Evolution Over Time, Alicia M. Grubb, Marsha Chechik

Computer Science: Faculty Publications

Goal modeling has long been used in the literature to model and reason about system requirements, constraints within the domain and environment, and stakeholders' goals. Goal model analysis helps stakeholders answer 'what if' questions enabling them to make tradeoff decisions about their project requirements. However, questions concerning the evolution over time of stakeholder requirements or changes in actor intentionality are not explicitly addressed by current approaches. In this paper, we tackle this problem by presenting a method for specifying changes in intentions over time, and a technique that uses simulation for asking a variety of 'what if' questions about such …

A Grand Unified Model For Liganded Gold Clusters, Wen Wu Xu, Beien Zhu, Xiao Cheng Zeng, Yi Gao

Xiao Cheng Zeng Publications

A grand unified model (GUM) is developed to achieve fundamental understanding of rich structures of all 71 liganded gold clusters reported to date. Inspired by the quark model by which composite particles (for example, protons and neutrons) are formed by combining three quarks (or flavours), here gold atoms are assigned three ‘flavours’ (namely, bottom, middle and top) to represent three possible valence states. The ‘composite particles’ in GUM are categorized into two groups: variants of triangular elementary block Au₃(2e) and tetrahedral elementary block Au₄(2e), all satisfying the duet rule (2e) of the valence shell, akin to …

Protecting Hatred Preserves Freedom: Why Offensive Expressions Command Constitutional Protection, Andrew P. Napolitano

Journal of Law and Policy

The First Amendment is not the guardian of taste. Instead, the U.S. Constitution wholeheartedly protects freedom of thought and expression, even if generated and defined by hatred, as long as that expression does not produce immediate lawless violence. Although free speech may lead to tenuous relationships or uncomfortable debates, it must be defended unconditionally. Too many politicians and lawmakers believe that the freedom of speech protected by the First Amendment attaches only to those ideas and expressions that they approve of; this is not so. This article argues that the Founders intended the First Amendment's free speech principle as a …

Implementation Of The Array-Based Approach For The Evaluation Of Randomness Of The Advanced Encryption Standard (Aes), Hanadi Yahia Alomari

Theses

Randomness is critical when it comes to cryptography. When a cryptographic system has randomness in it, it is impossible to decrypt the codes and break the system. To evaluate a cryptographic function’s randomness, many statistical tests were developed such as: Diehard and ENT, but these tests are not well suited for block ciphers. CryptoStat is the best statistical test suite to test the randomness of the Advanced Encryption Standard or AES, which is a block cipher established by NIST, the National Institute of Standard and Technology. An array based approach is also used to apply the CryptoStat test suite on …

Pricing And Reliability Enhancements In The San Diego Activity-Based Travel Model, Joel Freedman

PSU Transportation Seminars

The estimation of demand for priced highway lanes is becoming increasingly important to agencies seeking to improve mobility and find alternative revenue sources for the provision of transportation infrastructure.

However, many modeling tools fall short of what is required for robust estimates of demand with respect to toll and managed lanes in two key areas:

• The value-of-time is often aggregate and not consistently defined throughout the model system, and
• The reliability of transport infrastructure is rarely taken into account.

This presentation describes an effort which implemented recommendations of the Strategic Highway Research Program C04 and L03\L04 tracks on pricing and …

Re-Conceptualizing Research Misconceptions: Top Ten Myths Demystified, Faisal S. Al-Maamari Dr

i.e.: inquiry in education

It is generally acknowledged that novice researchers may not be adequately prepared to engage in/with research and that an increasingly widening divide exists between researchers and teachers, and therefore between research and practice. To explore this gap, this paper addresses ten of the most popular misconceptions novice researchers hold in engaging in research about their practice, and offers advice to these researchers towards teacher research engagement. Amongst the issues I describe are the various forms of research, the relationship between research and reflective or exploratory practice, issues pertaining to sampling, methods of data collection, research site access and the juxtaposition …

Engineering Design For Engineering Design: Benefits, Models, And Examples From Practice, Ken L. Turner Jr., Melissa Kirby, Sue Bober

i.e.: inquiry in education

Engineering design, a framework for studying and solving societal problems, is a key component of STEM education. It is also the area of greatest challenge within the Next Generation Science Standards, NGSS. Many teachers feel underprepared to teach or create activities that feature engineering design, and integrating a lesson plan of core content with an engineering design perspective can be a daunting task. Nevertheless, engineering design can be a useful tool in building students’ confidence in science, engaging students in science classes, building relationships with the community, and empowering under-represented groups.

The problem-solving approach of engineering design can become a …

Practitioner Research: A “Refreshing Change” For Professional Learning, Jennifer K. Allen

i.e.: inquiry in education

This article discusses a study that utilized a practitioner research approach to professional learning (Cochran-Smith & Lytle, 2009) that used student-created digital photo stories combined with focused teacher conversations guided by the NOT-ICE Teacher Discussion Protocol (Author, 2016) to explore why classroom teachers sometimes fail to notice the gifts and talents of emergent bilinguals of Latin@ heritage. Six elementary teachers participated in six small-group, collaborative discussion sessions in which they acted as co-researchers. Findings illuminate the significance of the research design in providing an effective professional learning experience. Highlighted design elements include the importance of using visual media as a …

The Impact Of Mindfulness-Based Interventions On Stress Eating, Emotional Eating, And Binge Eating: A Literature Review, Kira L. Minot

Food Science and Nutrition

This literature review examines the impact of various mindfulness-based interventions (MBIs) on the obesity-related eating behaviors of stress eating, emotional eating, and binge eating. With the inconsistency of the weight loss industry to provide long-term weight loss results, the United States is in need of alternative methods of weight loss and weight maintenance to combat the current overweight and obesity epidemic. MBIs are thought to be beneficial when targeted at behaviors of weight gain because mindfulness promotes an individual’s awareness of present physical and emotional sensations within the body, including hunger and satiety cues. Self-acceptance and stress reduction are also …

An Efficient And Long-Time Accurate Third-Order Algorithm For The Stokes–Darcy System, Wenbin Chen, Max Gunzburger, Dong Sun, Xiaoming Wang

Mathematics and Statistics Faculty Research & Creative Works

A third order in time numerical IMEX-type algorithm for the Stokes–Darcy system for flows in fluid saturated karst aquifers is proposed and analyzed. a novel third-order Adams–Moulton scheme is used for the discretization of the dissipative term whereas a third-order explicit Adams–Bashforth scheme is used for the time discretization of the interface term that couples the Stokes and Darcy components. the scheme is efficient in the sense that one needs to solve, at each time step, decoupled Stokes and Darcy problems. Therefore, legacy Stokes and Darcy solvers can be applied in parallel. the scheme is also unconditionally stable and, with …

Landsat 5 Thematic Mapper Reflectance And Ndvi 27-Year Time Series Inconsistencies Due To Satellite Orbit Change, Hankui Zhang, David P. Roy

GSCE Faculty Publications

The Landsat 5 Thematic Mapper (TM) sensor provided the longest single mission terrestrial remote sensing data record but temporally sparse station keeping maneuvers meant that the Landsat 5 orbit changed over the 27 year mission life. Long-term Landsat 5 TM reflectance inconsistencies may be introduced by orbit change induced solar zenith variations combined with surface reflectance anisotropy, commonly described by the Bi-directional Reflectance Distribution Function (BRDF). This study quantifies the local overpass time and observed solar zenith angle changes for all the Landsat 5 TM images available at two latitudinally separated locations along the same north-south Landsat path (27) in …
