Designing a portable surface roughness inspection probe

Designing a portable surface roughness inspection probe

114th Annual ASEE Conference and Exposition, 2007

作者： Moslehpour, Saeid Cloutier, Greg Brown, Matthew University of Hartford United States Electrical and Computer Engineering Department College of Engineering Technology and Architecture University of Hartford United States JDS Uniphase

The University of Hartford has been involved with the measurement of surface roughness using non-contact methods. The type of surface finish under study is created by a grinding operation in industrial applications. This surface must meet a specified pre-determined finish. Surface roughness is a measure of localized small-scale height variations or imperfections on the surface of a material. The measurement parameter of surface roughness is described by the term Ra, which is the average roughness expressed in micro-inches. One method used for non-contact measurement of a ground surface is to measure the back-scatter of a laser light source. The amount of back-scatter is directly proportional to the Ra value. One drawback to the current design is that it is not portable. A computer handles data acquisition and provides a user interface. The inspection probe is attached to the computer via a limited length of wire. In an industrial setting, it would be more efficient and flexible to bring the inspection probe to the surface in question rather than to bring the surface to the inspection probe. This design will eliminate the need for the wire tether and the computer altogether. The functionality for both data acquisition and user interface will be replaced by an embedded system. This embedded system will consist of a microcontroller, a multi-channel analog to digital converter, an LCD display, and a keypad input device. © American Society for Engineering Education, 2007.

Recognition of activities in an unobtrusive manner has attracted the attention of context aware systems, which provide end users with services based on everyday activities that are recognised without infringing the privacy of the end user. Current work has generally focused on applying a range of traditional classification and semantic reasoning based techniques in order to recognise these activities. However, the ability to recognise unexpected actions while the activity is being conducted remains a challenge. In this paper, we present an approach that is able to recognise activities regardless of the order of tasks/actions used to perform the activity. The proposed recognition framework extends an existing activity recognition approach by deploying a frequent pattern mining technique to find patterns among different streams of captured sensor events in order to increase the adaptive learning of the proposed recognition approach. © 2015 ACM.

Current consumer-grade computers and game devices incorporate very powerful processors that can be used to accelerate many classes of scientific codes. However, programming multi-core chips, hybrid multi-processors or graphical processing units is not an easy task for those programmers that deal mainly with sequential codes. In this paper, we explore the ability of the Cell Broadband Engine to run a particular Estimation of Distribution Algorithm. From an initial sequential version, we develop a multi-threaded one that is afterwards reworked to run on a Cell. The multi-threaded version is capable of efficiently use current multi-core chips, such as those used in desktop PCs. However, the efficiency of the Cell version is very low. We analyze the causes of these discouraging results, and provide some clues about the class of problems that could be efficiently ported to the Cell. © 2009 ACM.

Guided wave tomography allows the investigation of extended areas with a limited number of measurements, typically using transducer arrays. Most imaging methods rely heavily on the material properties such as dispersion curves, that in the case of fouling deposition are not always known. In the case of complex shaped structures, geometrical anisotropy can bring additional complexity. Here we present an unsupervised machine learning approach based on the Gaussian process to detect and characterize the fouling in a pipe bend that relies only on the difference between clean/healthy and fouled/damaged measured signals. © 2023 IEEE.

The SAMOS workshop is an international gathering of highly quali?ed researchers from academia and industry, sharing in a 3-day lively discussion on the quiet and - spiring northern mountainside of the Mediterranean island of Samos. As a tradition, the workshop features workshop presentations in the morning, while after lunch all kinds of informal discussions and nut-cracking gatherings take place. The workshop is unique in the sense that not only solved research problems are presented and discussed but also (partly) unsolved problems and in-depth topical reviews can be unleashed in the sci- ti?c arena. Consequently, the workshop provides the participants with an environment where collaboration rather than competition is fostered. The earlier workshops, SAMOS I–IV (2001–2004), were composed only of invited presentations. Due to increasing expressions of interest in the workshop, the Program Committee of SAMOS V decided to open the workshop for all submissions. As a result the SAMOS workshop gained an immediate popularity; a total of 114 submitted papers were received for evaluation. The papers came from 24 countries and regions: Austria (1), Belgium (2), Brazil (5), Canada (4), China (12), Cyprus (2), Czech Republic (1), Finland (15), France (6), Germany (8), Greece (5), Hong Kong (2), India (2), Iran (1), Korea (24), The Netherlands (7), Pakistan (1), Poland (2), Spain (2), Sweden (2), T- wan (1), Turkey (2), UK (2), and USA (5). We are grateful to all of the authors who submitted papers to the workshop.

A microgrid is an effective solution to enhance the integration of distributed renewable energy resources, which can operate both in grid connected mode and islanded mode. In order to reduce the jumps of the system variables within acceptable limits to ensure the system has good transient performance and power quality in multiple operating modes, seamless transfer is the key problem to be considered. In this paper, due to the different multiple equilibrium points for the two operating modes, the dynamics of every operating mode re modeled as a subsystem with all the variables that are needed to be synchronized. Linearization is carried out respectively for the two operation modes on the different equilibriums in a state-space form based on the small-signal stability method. To reduce the conservatism of the unified controller, the concept of the relative Lyapunov function is introduced to derive a multiple segmental Lyapunov method and a robust feedback mode-dependent switching controller is designed to achieve smooth transfer by making the deviation energy of the two modes both converge to the zero point. To rapidly detect the switching signal, a sparse communication network is introduced by the use of low bandwidth communication links to broadcast the switching signal to each distributed controller. Finally, two microgrid test systems were built in SIMULINK to show the feasibility and effectiveness of the proposed seamless transfer control strategies. © 2019 Chinese Automatic Control Society and John Wiley & Sons Australia, Ltd

The COVID-19 pathological test can be carried out with a sample taken from the nose, the back of the throat, or both, using a special swab. Currently, laboratories are checking through a process called Polymerase Chain Reaction (PCR) on a collected sample from the suspected person. PCR is used to find genetic material on the virus. PCR amplifies the genetic material such that the virus can be detected easily. In general, the PCR process is used to match the genetic material with the virus that causes COVID-19 is unique. Blood tests are also can be done to detect if a person has previously been exposed to the virus or not. This blood test is useful for knowing if a person may have developed immunity. In our paper, we propose a unique technique which will work on the microscopic image of Coronavirus affected tissue and detects the tissue is affected or damaged by the Coronavirus or not. In this research, we use the microscopic image(s) of a smear of epithelial throat/bronchial tract tissue. Firstly, image smoothing is conducted, and then Region of Interest (ROI) is detected. Then that 24-bit colour image (ROI) is converted to grey to bi-colour images using edge detection by setting a threshold. At last, the contours is detected and counted. In our technique, the resultant contours are the affected areas, and the count is the number of possible affected areas, an approximation. Thus, the infection depth can be guessed. Our technique is not only detecting the infection but also identifies the approximate number of attacked spots in a specific tissue area. Thus, the proposed technique identifies the person has COVID-19 or Coronavirus disease. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
