Work In Progress: Using Second Language Acquisition Techniques To Teach Programming - Results From A Two-Year Project, Christina Frederick, Lulu Sun

Publications

This WIP paper presents two years of findings for an NSF funded project under the Research Initiation Grant in Engineering Education (RIGEE) program. The project (SLA-aBLe) is currently in the second year of implementation and assessment. Final results from the project will be presented and discussed at the annual ASEE conference. The project used second language acquisition (SLA) theory and techniques to facilitate learning in an introductory programming language class. The project was developed by a multi-disciplinary team and involved multiple instructors and sections of an introductory programming language class using MATLAB. Each semester, instructors trained in SLA techniques taught …

The Application Of Second Language Acquisition To Programming Language Study, Lulu Sun, Christina Frederick, Li Ding, Rebecca Rohmeyer

Publications

This paper describes a design and implementation of a Second Language Acquisition in a Blended Learning (SLA-aBLe) project that aims to examine the efficacy of SLA approaches for teaching programming language. The project, which has been running for three semesters, modifies specific learning modules in a programming language class using a series of shorter videos with subtitles, online quizzes with tiered questions and comments, and a topic specified discussion board with Q&A sections. The SLA aspect of the SLA-aBLe study is emphasized through the use of strategies defined as best-practice SLA techniques, such as the inclusion of self-testing tired questions …

Rancang Bangun Pengukur Laju Detak Jantung Berbasis Plc Mikro, Dena Anugrah

Elinvo (Electronics, Informatics, and Vocational Education)

Artikel ini bertujuan untuk melakukan rancang bangun pengukur laju detak jantung yang terdiri dari perangkat keras dan perangkat lunak. Kalibrasi dilakukan dengan menggunakan alat medis Automatic Blood Pressure Monitor. Alat yang dirancang dibuat menggunakan PLC mikro yang diprogram dengan perangkat lunak LDmicro. Teknologi optik LED inframerah dan fotodioda digunakan untuk mendeteksi aliran darah di dalam kulit jari. Dari hasil pengukuran didapat bahwa alat ini memiliki tingkat kesalahan 0,198%. Nilai ini masih di bawah nilai kesalahan yang masih bisa ditolelir yakni sebesar 0,6745%. Jadi dapat disimpulkan bahwa alat yang dirancang dapat digunakan untuk mengukur laju detak jantung dengan akurasi yang sesuai …

Nuclear Power: Black Sky Liability Or Black Sky Asset?, Sherrell R. Greene

International Journal of Nuclear Security

Ready access to abundant electricity is a key enabler of modern life. During the past decade the vulnerability of Critical Infrastructure sectors in the U.S. to a variety of natural hazards and man-made threats has become increasingly apparent. The electrical infrastructure (the “Grid”) is the foundation for all other critical civil infrastructures upon which our society depends. Therefore, protection of the Grid is an energy security, homeland security, and national security issue of highest importance. Geomagnetic disturbances (GMD) induced by solar coronal mass ejections (CMEs), electromagnetic pulse (EMP) attacks, and cyber attacks are three events having the potential to plunge …

Evaluation Of Covert Plutonium Production From Unconventional Uranium Sources, Ondrej Chvala, Steven Skutnik, Tyrone Christopher Harris, Emily Anne Frame

International Journal of Nuclear Security

The potential for a relatively non-advanced nation to covertly acquire a significant quantity of weapons-grade plutonium using a gas-cooled, natural uranium-fueled reactor based on relatively primitive early published designed is evaluated in this article. The economic and technical issues that would influence the design decisions of a covert ²³⁹Pu production program are considered.

Several unconventional uranium acquisition approaches were explored. Methods for extracting uranium from enrichment tails, seawater, and coal ash sources were considered. The evaluation indicated that uranium extraction from coal ash or insitu leaching from underground deposits could be performed in economical manner that might be difficult …

Opportunities And Challenges In Developing Nuclear Security In Africa, James Larkin Mfr

International Journal of Nuclear Security

Those involved in nuclear security recognize that regions of significant instability in Africa have an impact on the safety and security of the continent's nuclear material and un-enriched uranium; however, some countries outside of continental Africa have taken counterproductive approaches to this issue. Despite challenges, the nuclear security community continues to develop and apply appropriate levels of nuclear security where needed. The community also takes every opportunity to make significant contributions to the global discourse on nuclear security culture.

Legal And Regulatory Framework Of Nuclear Security In Indonesia, Dahlia Cakrawati Sinaga

International Journal of Nuclear Security

Nuclear security is one of the most important topics for regulatory purposes in Indonesia. Nuclear security measures exist to prevent, detect, and respond to unauthorized removal of radioactive material and the sabotage of nuclear and radiation facilities. Indonesia participates in bilateral and multilateral cooperation and international events such as the Nuclear Security Summit. Indonesia has also ratified several international instruments related to nuclear security. Based on commitment to international events and ratification, Indonesia has developed nuclear security infrastructures by strengthening legislation and regulation, enhancing building capacity, and strengthening equipment and facilities. Badan Pengawas Tenaga Nuklir (BAPETEN) is Indonesia’s nuclear energy …

Nuclear Security Risk Analysis: An Insider-Outsider Collusion Scenario, Mohammad A. Hawila, Sunil S. Chirayath

International Journal of Nuclear Security

This study analyses the vulnerability of the physical protection system (PPS) deployed at a hypothetical facility. The PPS is designed to prevent and eliminate threats to nuclear materials and facilities. The analysis considers possible outsider and insider threats. A modified adversary sequence diagram (ASD) evaluates threat pathways to test an insider-outsider collusion case. The ASD also measures the probability of adversary interruption by demonstrating the methodology for a typical nuclear facility.

Nuclear Security Culture And Batan’S Assessment: Batan’S Experience, Anhar R. Antariksawan

International Journal of Nuclear Security

Organizations should increase safety to minimize the harmful effects of nuclear materials. Additionally, organizations should take measures to protect security culture within the organization itself. This paper covers the National Nuclear Energy Agency of Indonesia’s (BATAN’s) promotion of nuclear security culture and self- assessment projects, which is based on the International Atomic Energy Agency’s (IAEA) methodology.

Modified Fault Tree Method For Vulnerability Analysis Of Nuclear Medicine Facility Security System Case Study: Radiotherapy Facility, Sardjito General Hospital, Haryono Budi Santosa

International Journal of Nuclear Security

Assessing the vulnerability of physical protection systems (PPS) in nuclear medicine facilities is needed to prevent a security incident that could lead to the malicious use of nuclear material. Theft and sabotage of nuclear materials is becoming globally recognized. The current methods of assessing vulnerability tend to be oriented toward complex nuclear security; consequently, it is excessive to use such methods in simple facilities (i.e., radiotherapy facilities in hospitals).

The fault tree analysis is a method to assess vulnerability for a simple nuclear facility. The method’s primary events (i.e., basic events and undeveloped events) are able to accommodate fault causes …
