Accurate Indoor Navigation System Based On Imu/Lp-Mm Integrated Method Using Kalman Filter Algorithm, Abdullah Mohammed Bahasan

Hadhramout University Journal of Natural & Applied Sciences

Abstract

The demand for navigation systems is rapidly increasing, especially in indoor environments which the signal of GPS is not available. Therefore the Inertial Measurement Unit (IMU) system is a suitable navigation system in such indoor environments. It usually consists of three accelerometers and three gyroscopes to determine position, velocity and attitude information, respectively, without need of any external source. But this type of navigation systems has errors growth with time due to accelerometers and gyroscopes drifts. This paper introduces indoor navigation system based on integrated IMU navigation system with proposed system called Landmarks Points-Map Matching (LP-MM) system using Kalman …

Real-Time Illumination Capture And Rendering On Mobile Devices, Snehal Padhye, James A. Ferwerda

Frameless

We present our efforts to develop methods for rendering 3D objects on mobile devices using real-world dynamic illumination from the user’s environment. To achieve this, we use the front and back cameras on the mobile device to estimate the light distribution in the environment in real time. We then create a dynamic illumination map and render the object at interactive rates in a browser on the device using a web-based graphics API. This project achieves one of the goals of our related work on realistic visualization of virtual objects: to make virtual objects appear to be situated within the scene …

Mixed Reality Prototype Device Showcase: Using Smart Glasses To Enhance Language Access, Aaron Parker, Connor Switenky, Roshan Mathew, Wendy Dannels

Frameless

While the use of American Sign Language (ASL) interpreters and real-time captioning significantly increases deaf individuals’ ability to participate in a wide variety of functions, there are some limitations. The major problem is that current ways of providing communication and information access to deaf people require them to split their attention between the visual focus of the specific content and the interpreter/captioning display. At any given point in time, deaf people are forced to decide what explanation to miss with subsequent effects on topic comprehension and perceptions of the interaction and environments.

Epics Urban Farming: Bringing Sustainable Fresh Food To Gary, Indiana, Elijah Klein

Purdue Journal of Service-Learning and International Engagement

EPICS Urban Farming is a team of seventeen undergraduate students designing and implementing an aquaponics and food distribution system in Gary, Indiana. With the area being a food desert, most people turn to corner stores for food that is easily accessible and cheap but unhealthy. From this diet, there are quite a few widespread health concerns that the population of Gary, Indiana, faces daily. For example, obesity, diabetes, and heart conditions are some of the most common diseases that plague the community. Urban Farming is working to aid in combating these issues with the partnership of Pastor Marty Henderson, who …

A Study Of Static And Dynamic Characteristics Of Multifunctional Signal Converters, Akmal Abdumalikov

Chemical Technology, Control and Management

The issues of continuity, accuracy, speed and reliability of signal conversion, which are the main problems of quality control and management of production processes, remain relevant. Research shows that in practice there are different signal variables, the study of which is highly formalized in a number of modeling tasks and basic classification studies, in particular transients in converters, its sources and elements requires a unified mathematical approach, that is, visual, highly formalized modeling and research based on it. The paper presents a graph model of multifunctional signal converters that provide microprocessor and electronic devices with signals in the form of …

Answering Food Insecurity: Serving The Community With Food And Knowledge Using Technology, Courtney Simpson

Purdue Journal of Service-Learning and International Engagement

The courses of Tech120, CGT110, and ENGT 180/181 and Red Gold at Purdue collaborated to design a robot that would plant and water a garden for a local community charter school. The students centered the project on the users’ needs for fresh food, nutrition education, and early exposure to STEM for children. The school, Anderson Preparatory Academy (APA), is comprised of many children who come from low-income families and are in the free or reduced lunch program. Inspired from “Farm Bot,” a similar system that allows for almost hands-free gardening, the “Boiler Bot” is designed to be scalable so children …

Graphene Valley, Daniel Applebaum

Missouri S&T’s Peer to Peer

Silicon Valley in northern California is the proverbial hub of technological innovation and industry. Its namesake derives from the fact that silicon acts as the main component in modern electronics; however, a new material called graphene is challenging its role. In its early years of research, it was evident that the qualities of graphene far exceeded expectations. Industries are going mad trying to come up with applications and consumer products. While headway has been made, it is hard to say how long it will take to see products advertising their new graphene capabilities. Before touch screens or graphene-based microprocessors can …

Applications Of Ultrasonic Non-Destructive Testing In 3d Printing, Parker Lawley

The Journal of Undergraduate Research

To determine the capabilities of ultrasonic non-destructive testing methods in 3D printing, test specimens were designed to evaluate advantages and limitations in using ultrasoundC-scanning to determine 3D printing effectiveness. A Matlab program was written to process the data obtained from the UTwin software and ultrasound tank, as well as produce 3D models of the parts being tested. Thickness, types of features, and various printing methods were evaluated to determine how these characteristics vary in effectiveness of C-scan imaging. Results from the UTwin software C-scans were compared to the Matlab program’s imaging and three-dimensional modeling. After determining the capabilities of ultrasonic …

High Definition 3d Printing – Comparing Sla And Fdm Printing Technologies, Tyler Finnes

The Journal of Undergraduate Research

For consumer level additive manufacturing, there are currently two main methods to 3D print objects: Stereo lithography and Fused Deposition Modeling. Both processes add material, layer by layer, to create objects. Stereo lithography (SLA) uses a UV light source to selectively cure resin while Fused Deposition Modeling (FDM) extrudes semi-liquid plastic in a specific layout to create objects. As with most technologies, both styles of printing have advantages and disadvantages. The biggest advantage of SLA 3D printing is very high resolution. SLA 3D printing can produce objects with more than double the resolution of FDM printers. The mUVe 3D SLA …

Is Tech M&A Value-Additive?, Ani Deshmukh

Undergraduate Economic Review

Given rising M&A deal volume across all high-tech subsectors, the ability to measure post-acquisition performance becomes critical. Despite this growth, the relevant academic literature is severely lacking (Kohers and Kohers 2000). Using an event-study approach, I find that acquirers and targets both realize statistically significant day-0 abnormal returns (1.23% [p<0.1] and 8.1% [p<0.01], respectively). As positive stock returns signal positive growth prospects in a semi-strong efficient market, AR regressions found that firms' technological relatedness, deal financing, purchase price premiums, and the relative book to market ratio, explained most variance. Overall, high-tech transactions are value-additive for both targets and acquirers.
