Pedestrian Intent Recognition (PIR) is a system for predicting future positions and trajectories of pedestrians on board an autonomous vehicle. Using the OpenPose library as a basis, a model was created using a feed forward neural network based on 3D skeletal posture to predict future pedestrian positions. The predictive model results in an accurate depiction of pedestrian actions as trained on the Carnegie Mellon Mo-Cap Dataset. PIR functions as a proof of concept that can be adapted to an autonomous vehicle platform. Future work includes adapting the model to function using LIDAR and multiple RGB cameras as input for a real-time prediction system for autonomous vehicles

To expand on the level of interaction that is had with the player, mood-detection has been implemented to obtain data about their mood in realtime. This provides information that can be used to enhance the player experience. This project aims to provide features of mood detection that will enable both real-time adjustments to a player’s gaming experience and options for offline data analytics. The motivation behind integrating mood-detection into gaming machines is to allow those at IGT to analyze what makes a game interesting and add a new layer of interaction between the player and machine, increasing both player enjoyment and player retention

Software is often used to keep track of data regarding the frequency and magnitude of these vibrations. General Electric currently has to bring out expensive equipment to log and convert the data from the software into relevant and readable data, risking the equipment in the process. The goal of this project was to use a Renesas Embedded GUI board to create a device that no longer requires bringing out expensive equipment to read the data. The board logs the data and makes it possible for the information to be saved onto a USB stick. The data then is sent to a remote computer and converted into usable data
PINCH: A Proprietary Interface for Network Communication with Hardware

This task will require network communication between the server hosting the game and the hardware in the machine. Communication with the hardware is already implemented by the operating system, so we will implement a layered architecture that will allow the server to communicate securely with the hardware interface in the operating system. Messages from the server will be sent to a network communication layer via secure TCP sockets, and this layer will communicate directly with the operating system. This will allow players to insert money and collect winnings, and allow the game to access players’ card information or even trigger machine tilts
A Video Library Management Software Toolkit for the Nevada Climate Change Portal
No full textWeb-based video libraries represent a recognized and useful method of gathering contributions in the form of videos to research information that is provided from various users. Video libraries can be more effective and innovative, as compared to other more usual forms of video libraries, in terms of accessibility, flexibility, streaming, cost, and several other factors. These factors are essential for the development of commercial video library management toolkits and are being increasingly adopted in commercial web-based video libraries.The Video Library Management Software Toolkit for the Nevada Climate Change Portal (in short, VLMST for NCCP) presented in the thesis is a web-based video management system designed to be integrated in the Nevada Climate Change Portal (NCCP) that is being developed at the University of Nevada, Reno as a part of the NSF EPSCoR funded project Nevada Infrastructure for Climate Change Science, Education and Outreach. One of the primary goals of this toolkit is to ensure that the users of the Nevada Climate Change Data Portal have equal access to participate in, contribute to, and benefit from all the functionalities provided by this specialized video library. VLMST is a web-based video repository that uses the server-client technology, which allows management and sharing of videos for the purpose of enhancing research and education. The proposed solution incorporates the forthcoming HTML5 technology, including the accessible video capability, allowing users to utilize cross-browser compatible video control. The thesis presents the software specification, the design, and the prototype of the VLMST. It highlights VLMST's distinguishing characteristics, compares it with several related tools, and points to a number of directions of future work
Environment for Large Data Processing and Visualization Using MongoDB
No full textData means treasures to both scientists and business people. Scientists can discover significant rules and theories beneath data. People involved in business can find their potential customers and improvement suggestions from exploring data. To uncover these valuable treasures, we need effective and efficient tools. There are some traditional quality data management, processing, and visualization tools and systems. However, most of them are no longer as powerful as before when the data size grows larger. These tools and systems may respond slower or even stop working because of increasingly large data volumes. We are now in the digital era. Data is generated at an amazingly high speed. Remarkably, 90% of the data in the whole world has been generated in the last two years. To manage, process, and visualize large data, we need new tools and systems.In this thesis, we introduce the ELDP&V system. It is designed to manage, process, and visualize large data. We used MongoDB to record file paths and stored files in a filesystem to manage data. By using this method, we do not need to create different schemas for different files. The system offers users basic data processing methods, such as distribution frequency histograms. It also provides scientific models for users for data processing. ELDP&V can visualize data with line charts, bar charts, and 2D maps. Most of the visualization results are interactive. We implemented ELDP&V with some new ideas and design workflows, which led to higher performance. For example, in a test we performed the system has visualized 13,455,368 records in 50 seconds. We tested the same dataset with some traditional web-based tools. They stopped working or produced some errors. When ELDP&V visualizes a time-based file, it displays the chosen items based on timestamps. This means the loading time will not be affected by the file size.The thesis presents background on big data, outlines ELDP&V’s goals and characteristics, the proposed system’s design, and demonstrates its prototype in action. It also contains a comparison with related work and provides several pointers to directions of future work
Haptic Interface for Non-Visual Steering
No full textGlare significantly diminishes visual perception, and is a significant cause of traffic accidents. Existing haptic automotive interfaces typically indicate when and in which direction to steer, but they don't convey how much to steer, as a driver typically determines this using visual feedback. We present a novel haptic interface that relies on an intelligent vehicle positioning system to indicate when, in which direction and how far to steer, as to facilitate steering without any visual feedback. Our interface may improve driving safety when a driver is temporarily blinded, for example, due to glare or fog. Three user studies were performed, the first study tries to understand driving using visual feedback, the second study evaluates two different haptic encoding mechanisms with no visual feedback present, and a third study evaluates the supplemental effect of haptic feedback when used in conjunction with visual feedback. Studies show this interface to allow for blind steering through small curves and that it can improve a driver's lane keeping ability when combined with visual feedback. We improved our interface to identify whether this allows for blind steering with no visual feedback by users who are blind. We conducted a user study with an adapted version of our interface that implements self correction and conducted user studies with users who are blind
Mitigation Of Electromagnetic Interference In Pulse Width Modulated Voltage Source Inverters And Communication Enhancement In Power Lines
Full text linkMost of the modern society's conveniences depend on electrical energy. The power supplied by the system can be considered as raw power and often it must be conditioned according to the application. The conditioning process is done by power electronic converters using semiconductor switches. This work involves the operation of pulse width modulated inverters. Because of the high switching rate of the semiconductor switches harmonics are generated in the output voltage and current of the inverter. These harmonics result in propagation of electromagnetic noise in the power electronic system. This work explains how the harmonic pollution can be mitigated by randomizing the switching period of the pulse width modulated inverter. In particular, an advanced spectral shaping technique is presented, which produces spectral nulls at selected frequencies. The spectral nulls can then be used as communication channels in power line communication systems
