TREESAPP, VERSION 2.0
TreeSap was built to allow nature enthusiasts to identify and understand the value of trees throughout the Holland, Michigan area. Using data collected by Hope College and the City of Holland, users can identify trees via their current location, manual coordiate entry, map, and QR code. Additionally, users can add their own trees to the database and have their trees reviewed and approved by trusted curators.
Future versions of TreeSap could include the ability to add notes and images to existing trees, as well as the ability for curators to edit pending trees before accepting or rejecting them.
Josiah Brett (East Lansing), Jonathan Chaffer (Grand Rapids, Michigan), Micah Chrisman (Sheboygan, Wisconsin) and Josie Crane (Mattawan, Michigan) are all junior Computer Science majors at Hope College. They completed their work on TreeSap as part of the Computer Science department's Hope Software Insitute during a 9-week period in the summer. In addition to software development, they enjoyed drawing creative "frogs" on the lab's white board and weekly trips to various local eateries for lunch. Their work was supervised by Dr. Jipping.

THE HELPME WEB APPLICATION: ENHANCING COMMUNICATION WITHIN INSTRUCTIONAL LAB SETTINGS
Stressful college labs are all too familiar to today’s students due to the imbalance of instructional staff (professors and TAs) and the students’ need for assistance. Students are often left waiting for help, hindering their ability to utilize lab time effectively. It can also leave instructors stressed and exasperated, especially when the same question is asked repeatedly.
We created the HelpMe application to better facilitate communication during labs between students and instructors. As students enter their questions into the system, the instructional staff is alerted. Instructors can then provide detailed information to the student and allow other students to access and benefit from the answer via HelpMe. This allows students to work at their own pace and avoids the pitfall of many students having the same question and needing assistance. Our overarching vision is to better provide students with the support they need by providing access to the necessary information and allowing instructional staff to use their time as effectively as possible.
Our presentation will describe how HelpMe enhances rather than replaces human interaction by addressing its features and future uses. We performed two beta tests over the course of the summer and will describe what we learned from these two tests. Attendees will have a chance to interact with the HelpMe application as part of the presentation.
Gabrielle Kosiba (Farmington Hills, Michigan), Claire Lundy (Okemos, Michigan), and Carmen Rodriguez (Tegucigalpa, Honduras) are all sophomore Computer Science majors at Hope College. They completed their work on the HelpMe application as part of the Computer Science department's Hope Software Insitute during a nine-week period in the summer. In addition to software development, they enjoyed hourly workout breaks, weekly trips to various local eateries for lunch and a highly competitive evening of Spike Ball. Their work was supervised by Dr. McFall.

Maia: A Language for Mandatory Integrity Controls of Arbitrary Structured Data
The expansion of attacks against information systems of companies, that operate nuclear power stations and other energy facilities in the United States and other countries, are noticeable with potential catastrophic real-world implications. Data integrity is a fundamental component of information security. It refers to the accuracy and the trustworthiness of data or resources. Data integrity within information systems becomes an important factor of security protection as the data becomes more integrated and crucial to decision-making. The security threats brought by human errors whether, malicious or unintentional, such as viruses, hacking, and many other cyber threats, are dangerous and require mandatory integrity protection. To date, Biba and Clark-Wilson are well-known general integrity models in computer systems but they impose a number of restrictions that make them impractical to implement. Additionally, permission-based solutions are one of the popular approaches in the literature but existing solutions are designed to address the trustworthiness of who accesses the data not the trustworthiness of the data itself. To solve these problems, we propose a generally applicable system to prevent and detect compromised data integrity.
The proposed work consists of two major components: the definition of the language for describing integrity constraints, and the construction of the mandatory integrity control model. The main idea of this research is to describe the integrity constraints for arbitrary structured data. In addition, we propose to construct a set of specification rules that enables users to identify the clearance levels of their tested data using Multi-Level Security (MLS). Furthermore, we use Structural Operational Semantic (SOS) to evaluate and validate our approach. Also, we will provide an evaluation study in term of the effectiveness and usability of our system in the classroom. By using our mandatory integrity protection approach, companies and organizations can ensure data integrity in their information systems.

Soter: Trust Discovery Framework for the Internet of Medical things (IoMT)While the Internet of Things is in the rise in the healthcare industry, implementation of this technology has not been as rapid as in many other sectors-largely because of the strict HIPAA compliance. In this talk, we propose Soter a HIPAA compliance distributed personalized authentication mechanism for the Internet of Medical Things (IoMT), based on Multiparty Trust Negotiation. Multiparty Trust Negotiation (MTN) is a promising approach for establishing trust between multiparty (Things) demanding to share resources, by gradually exchanging digital credentials based Access Control Policies (ACP). Previous work has been proposed for authentication in IoMT environment, however the proposed approaches are not the best for IoMT as they are centralized and based on Identity Access Control Policies (IBAC) which have limitations make them unsuitable for open distributed environment such as the IoMT, we explain these limitations on the next section. Soter framework presents a number of innovative features, such as the use of Multiparty Trust Negotiation (MTN) to establish trust between Medical Things, and the use of Personalized Access Control Policies (PACP).
Maha Allouzi is currently a PhD candidate at Kent State University and received her Master’s degree in computer science at Kent State University.

Scalable Algorithms and Hybrid Parallelization Strategies for Multivariate Integration with ParAdapt and CUDAThe evaluation of numerical integrals finds applications in fields such as High Energy Physics, Bayesian Statistics, Stochastic Geometry, Molecular Modeling and Medical Physics. The erratic behavior of some integrands due to singularities, peaks, or ridges in the integration region suggests the need for reliable algorithms and software that not only provide an estimation of the integral with a level of accuracy acceptable to the user, but also perform this task in a timely manner. We developed ParAdapt, a numerical integration software based on a classic global adaptive strategy, which employs Graphical Processing Units (GPUs) in providing integral evaluations. Specifically, ParAdapt applies adaptive region partitioning strategies developed for efficient integration and mapping to GPUs. The resulting methods render the framework of the classic global adaptive scheme suitable for general functions in moderate dimensions, say 10 to 25. The algorithms presented have been determined to be scalable as evidenced by speedup values in the double and triple digits up to very large numbers of subdivisions. An analysis of the various partitioning and parallelization strategies is given.
Prior to coming to the United States to pursue a PhD degree, Fola worked for some years at PricewaterhouseCoopers in Nigeria, working with teams to provide assurance services to the firm’s clients.
Her research areas include: high performance computing, applying GPUs and CUDA to scientific computations including the estimation of multivariate numerical integrals from diverse fields such as Bayesian Statistics and High Energy Physics.
Fola obtained her Bachelors in Computer Science from University of Lagos, Lagos, Nigeria, and her M.S. degree in Computer Science from the University of Massachusetts at Boston.

Why Microsoft is the #1 Company Developers Should be Watching
For many years, development was pretty simple. You could realistically learn everything there was to know about your technology of choice, you did all your work on your own computer, and the development world was split neatly into two camps: enterprise and open-source. Today, all of those lines have blurred into each other.--development rarely happens without use of the cloud, enterprise frameworks like Microsoft's .NET have gone open-source, and virtually no one can afford to only develop using a single technology. During this transition, Microsoft made some deft technology moves that, in my opinion, make it the most important company for professional software developers to watch.
In this talk, I'll give you a quick survey of some of the most important technologies coming out of Microsoft today, including .NET Core, Xamarin, and Blazor for doing cross-platform development, great tooling like Visual Studio for Mac and Visual Studio Code, and some of Microsoft's game-changing cloud services like Azure Functions, Machine Learning, AI, and Azure DevOps. Even if you currently know nothing about Microsoft's development technologies, you will walk away with a good overview of what's happening at software development's most important company.

AI is an issue of increasingly urgent international import. In 2017, Russian President Vladimir Putin declared that the control of artificial intelligence will be crucial to global power. In a “science lesson” to start the Russian school year, Putin said that artificial intelligence is “the future, not only for Russia, but for all humankind.” Tech writer Kevin Kelly calls AI, “the ur-force in our future. The term artificial intelligence came into wide use among computer scientists after MIT researcher John McCarthy imagined in 1960 the possibility of computers not simply managing data, but thinking like human beings. In 1989 mathematician Roger Penrose defined the “objectives” of AI as “to imitate, by means of machines…as much of human mental activity as possible, and perhaps to improve upon human abilities in these respects.”
Despite such assessments--and despite the fact that the stakes could not be higher—AI remains enigmatic and poorly understood by the public. The language we employ to describe AI will have important consequences for the technology’s future development and regulation. As a result, efforts to craft linguistic frames for AI are in full swing. Journalist Andrea Morris writes that “we may need a vernacular to talk about non-biological superintelligent agents who display highly skilled behaviors.” That new vernacular is being forged in contemporary public discourse about AI. This presentation will explore six prominent efforts to frame AI for contemporary audiences, and the implications of each.
James A. Herrick (MA University of California-Davis, PhD University of Wisconsin) is the Guy Vander Jagt Professor of Communication at Hope. Professor Herrick is the author or editor of three books on the rhetoric of technology.

Exploring the Tradeoffs Between Performance and Power for Parallel Applications
The demand for computational power continues to drive the deployment of ever-growing parallel systems. Production parallel systems with hundreds of thousands of components are being designed and deployed. Future parallel systems are expected to have millions of processors and hundreds of millions of cores, with power requirements. The complexity of these systems is increasing, with hierarchically configured manycore processors and accelerators, together with a deep and complex memory hierarchy. As a result of the complexity, applications face an enormous challenge in exploiting the necessary parameters for efficient execution. While reducing execution time is still the major objective for high performance computing, future systems and applications will have additional power requirements that represent a multidimensional tuning challenge. To embrace these key challenges, we must understand the complicated tradeoffs among runtime and power, and in some cases resilience strategies. This talk will present our methods and analyses to explore these tradeoffs for parallel applications.
The lectureship is supported by a multi-year grant from the Kavli Foundation of Oxnard, California, to bring prominent scientists to campus.

Social Media Consumers and Curators
People frequently rely on social media as their primary source of news and information. Tasked with curating an ever-increasing amount of content, providers leverage user interaction feedback to make decisions about which content to display, highlight, and hide. User interactions such as likes, votes, clicks, and views are assumed to be a proxy of a content's quality, popularity, or news-worthiness. Users in turn rely on the anonymous, aggregate ratings of others to make important decisions about which products to buy, movies to watch, news to read, or even political candidates to support. The sheer volume of new information being produced and consumed only increases the reliance that individuals place on anonymous others to curate and sort massive amounts of information. As crowd-sourced curation of news and information have become the norm, it is important to understand not only how individuals consume information through social news Web sites, but also how they contribute to their ranking systems and to the spread and reception of news and misinformation.
Maria Glenski is a PhD Candidate in Computer Science and Engineering at the University of Notre Dame. She is an Arthur J Schmitt Leadership in Science and Engineering Fellow, a member of the Interdisciplinary Center for Network Science and Applications (iCeNSA), and has served on the program committee for the international AAAI conference on web and social media (ICWSM).

Inclusive Design, Ethical Tech, and All of Us
We all want design to be a force for good—we want to make things welcoming, seamless, and maybe even fun to use. But without a process for ensuring our design decisions are also inclusive, equitable, and fair, our products can end up with all sorts of biases embedded in them. At best, these biases leave people out or let them down, like a “smart scale” that assumes everyone wants to lose weight, or a celebratory notification sent out to a grieving user. At worst, they can cause lasting harm: résumé-review algorithms trained to weed out women candidates, facial-recognition services that fail for people of color, “recommended content” features that put increasingly disturbing and violent content in front of kids.
In this talk, we’ll look at the ways tech and design have gone wrong—and then talk about what needs to happen to prevent these problems in our own work, and to push tech companies to adopt a more ethical and inclusive way forward.
