Description
This paper presents work that was done to create a system capable of facial expression recognition (FER) using deep convolutional neural networks (CNNs) and test multiple configurations and methods. CNNs are able to extract powerful information about an image using multiple layers of generic feature detectors. The extracted information can be used to understand the image better through recognizing different features present within the image. Deep CNNs, however, require training sets that can be larger than a million pictures in order to fine tune their feature detectors. For the case of facial expression datasets, none of these large datasets are available. Due to this limited availability of data required to train a new CNN, the idea of using naïve domain adaptation is explored. Instead of creating and using a new CNN trained specifically to extract features related to FER, a previously trained CNN originally trained for another computer vision task is used. Work for this research involved creating a system that can run a CNN, can extract feature vectors from the CNN, and can classify these extracted features. Once this system was built, different aspects of the system were tested and tuned. These aspects include the pre-trained CNN that was used, the layer from which features were extracted, normalization used on input images, and training data for the classifier. Once properly tuned, the created system returned results more accurate than previous attempts on facial expression recognition. Based on these positive results, naïve domain adaptation is shown to successfully leverage advantages of deep CNNs for facial expression recognition.

Description
This paper presents the design and evaluation of a haptic interface for augmenting human-human interpersonal interactions by delivering facial expressions of an interaction partner to an individual who is blind using a visual-to-tactile mapping of facial action units and emotions. Pancake shaftless vibration motors are mounted on the back of a chair to provide vibrotactile stimulation in the context of a dyadic (one-on-one) interaction across a table. This work explores the design of spatiotemporal vibration patterns that can be used to convey the basic building blocks of facial movements according to the Facial Action Unit Coding System. A behavioral study was conducted to explore the factors that influence the naturalness of conveying affect using vibrotactile cues.

Description
This paper presents a system to deliver automated, noninvasive, and effective fine motor rehabilitation through a rhythm-based game using a Leap Motion Controller. The system is a rhythm game where hand gestures are used as input and must match the rhythm and gestures shown on screen, thus allowing a physical therapist to represent an exercise session involving the user's hand and finger joints as a series of patterns. Fine motor rehabilitation plays an important role in the recovery and improvement of the effects of stroke, Parkinson's disease, multiple sclerosis, and more. Individuals with these conditions possess a wide range of impairment in terms of fine motor movement. The serious game developed takes this into account and is designed to work with individuals with different levels of impairment. In a pilot study, under partnership with South West Advanced Neurological Rehabilitation (SWAN Rehab) in Phoenix, Arizona, we compared the performance of individuals with fine motor impairment to individuals without this impairment to determine whether a human-centered approach and adapting to an user's range of motion can allow an individual with fine motor impairment to perform at a similar level as a non-impaired user.

Description
This paper presents an overview of The Dyadic Interaction Assistant for Individuals with Visual Impairments with a focus on the software component. The system is designed to communicate facial information (facial Action Units, facial expressions, and facial features) to an individual with visual impairments in a dyadic interaction between two people sitting across from each other. Comprised of (1) a webcam, (2) software, and (3) a haptic device, the system can also be described as a series of input, processing, and output stages, respectively. The processing stage of the system builds on the open source FaceTracker software and the application Computer Expression Recognition Toolbox (CERT). While these two sources provide the facial data, the program developed through the IDE Qt Creator and several AppleScripts are used to adapt the information to a Graphical User Interface (GUI) and output the data to a comma-separated values (CSV) file. It is the first software to convey all 3 types of facial information at once in real-time. Future work includes testing and evaluating the quality of the software with human subjects (both sighted and blind/low vision), integrating the haptic device to complete the system, and evaluating the entire system with human subjects (sighted and blind/low vision).

Description
Currently, Arizona State University's West Campus offers students a Bachelor's of Science degree in Forensics. This degree program has been at ASU's West campus for over three years now and is at its capacity of 300 students due to limitations on lab space. In order to support the growth and provide students with a valuable experience, the Math and Natural Sciences department seeks to create a "fee-for-service" enterprise within the Forensics division. This new lab called the Arizona State University Forensic Science Center (ASU-FSC) would serve city, county, state, and federal government agencies. The mission of the ASU-FSC is to provide robust, accurate and efficient forensic services while leading innovation in research and education in forensics for Arizona, the Southwest and the country. The School of Natural Science and Mathematics has sought help from W. P. Carey School of Business students to analyze the possibility of adding a Forensics fee-for-service lab to ASU West campus. The deliverables from this report will provide a comprehensive marketing, supply chain and financial review of all aspects of the business, and will aid in the decision making process for the creation of the Arizona State University Forensic Science Center.

What if unplanned free time could be spent with friends instead of trying to contact them? This app will do that by connecting you with friends who are ready to hang out. Kickback is a mobile app designed to connect individuals with their friends and businesses that offer opportunities to socialize in a group setting. The idea had been floating around in my head for a few years and this creative project gave me the opportunity to try my hand at making the idea into a reality. This thesis is a combination of technical efforts and business know-how that I had to learn in order to keep up along the way.

Description
The purpose of this thesis is to convince readers of the benefits of cross-functional collaboration and innovation within the W. P. Carey School of Business. Specifically, cross-functional collaboration is the "innovation" that is being discussed and will be presented. Written from the perspective of a current business student, this thesis incorporates secondary research as well as personal experience to explain why this would benefit the business school at Arizona State University. The research conducted stems from online resources such as the Harvard Business Review, Kai Nexus, Forbes and other websites and explains why the author decided to pursue this topic. Cross-functional collaboration is seen in the everyday workings of the business world and are a utilized by a multitude of successful companies \u2014 Dell, Intel, Amazon, Apple and other similar companies. Therefore, it should be taken advantage of within undergraduate education in order to better prepare students for what they may experience afterwards. In addition, a majority of the paper is dedicated to recommendations for how exactly cross-functional collaboration could be incorporated, as well as examples of successful cross-functional courses and teams. These recommendations will be beneficial to business and general faculty members and can contribute to positive organizational change at the university.

In the current age of global climate crisis, corporations must confront the rising pressure to mitigate their environmental impacts. The goal of this research paper is to provide corporations with a resource to manage waste through the implementation of a circular economy and by increasing Corporate Social Responsibility (CSR). Navigating this large and complex system required the use of various methodologies including: the investigation of the relationships between waste management systems and sustainable development across major companies; literature reviews of scholarly articles about CSR, circular economies, recycling, and releases of company reports on sustainable development and financials. Lastly, interviews and a survey were conducted to gain deeper insight into the problems that make circular economies so difficult to achieve at scale.
