- Design Of A Miniature Base Isolation DemoPatil, Saurabh; Baishya, Ronit; Li, Yuhao (2023-05-15)In this project, we will design a miniature base isolation demo. The objective is to design the total mass, stiffness, and damping (mb, kb, cb) of a base isolation system for a single-story building, subject to the design spectrum described below. An effective isolator will result in a maximum moment that is significantly lower than that of the no-isolation case (fixed base). The target reduction in the base moment is shown in Table 1. The challenge is that as you make the isolator more flexible, it will also deform more and could break as well, so we also will place a limit on the maximum allowed deformation.
- Image Processing Approach For Creating An Alert System For Active Induction/StoveBaishya, Ronit (2023-12-15)The problem-focused to be solved through this project is that after cooking many times people forget to switch off the burner or induction. This might be a serious issue as it might cause a house fire. For the project, a Pi camera along with Raspberry Pi would be used as the setup, where the camera will collect data that can be used for computer vision and image processing. The techniques used in this project are divided into two parts. First is to separate the light source in the regulator area image and second use edge detection to separate the utensils on the stove/burner and empty the stove/burner. The creation of the actual alert system was not covered in the presentation.
- Review Of Bridge Structural Inspection Aided By Augmented RealityBaishya, Ronit (2023-12-15)In tackling the pressing concern of deteriorating infrastructure, the integration of element-level condition ratings and the digitization of the national bridge inventory stands out as a crucial response, not only refining the quality of inspection data but also unlocking the potential for machine learning and statistical methods to forecast future infrastructure conditions. AR emerges as a beacon of promise, touted as a tool capable of elevating the quality, precision, and efficiency of bridge inspections. AR is a technology that blends computer-generated information with the user's real-world environment in real time. Unlike virtual reality, which creates a completely artificial environment, augmented reality enhances the existing surroundings by overlaying digital information, such as images, videos, or 3D models, onto the physical world. AR is typically experienced through devices like smartphones, tablets, smart glasses, or AR headsets. It has applications in various fields, including gaming, education, healthcare, manufacturing, and navigation. For example, AR can be used to display additional information about a product when a user points their smartphone camera at it, or it can provide real-time navigation cues overlaid on the street view seen through smart glasses. However, the technology, despite its potential, remains in its infancy within this domain, grappling with various implementation challenges in structural and infrastructure health monitoring. The purpose of this review is to provide an overview of both state of the practice and state of the art applications of AR and related technologies in the bridge inspection context. Based on this overview, key research gaps are identified and discussed. This study ventures into the exploration of Augmented Reality (AR) and immerses itself in the latest developments and the transformative influence it could wield on the digital aspects of bridge inspection. It addresses many aspects of bridge structural inspection aided by augmented reality, such as (i) the process of AR bridge inspection (ii) the present stage and future implementation in the industry (iii) software (iv) challenges, and (v) the future of AR.
- A Study Of Dynamic Forces Due To Human Movement On StairsBaishya, Ronit; Setareh, Mehdi (2022-12-30)In recent times there has been an improvement in computerized analysis and design of structures which have resulted in longer span and lightweight structures. The structures are strong enough to carry loads but due to their lightness and slenderness, they are more susceptible to vibration due to human movements. Structural engineers need to address the vibration issue and find the underlying reason and to solve or reduce the issue with knowledge and experience. The main objective of this research is to define the dynamic forces due to human movement on stairs. The data was the measurements of ground reaction forces (GRF) from several individuals ascending and descending a prototype rigid stair located at the Virginia Tech Vibration Testing Laboratory using an instrumented force plate to measure the exerted forces. The weight of each individual was also measured by the same force plate. Considering the periodicity of human excitation force, the Fourier Series parameters (Fourier Coefficients or Dynamic Load Factor (DLF) and corresponding phase angles) of the measured forcing functions were computed. Relationships between the DLFs and their associated phase angles as a function of the step frequencies were established.
