Evaluation of Acceleration Signal Frequency Results on Bearing Shell Non-destructive Testing, Ultrasonic Waves, Simulation
Abstract: Bearings are used in many rotary machines. Defects in them can cause car breakdowns, loss of production, and even catastrophic accidents. This makes them difficult to maintain and will make it costly to repair and maintain. Therefore, detecting defects in bearing vibrations is an important issue for the industry. On the other hand, error-related frequencies may be identified as discrete frequency lines, and therefore error characteristics cannot be easily identified.For …

Significant Prolongation of QTc-Interval in Overweight-Obese Hypertensive Patients Does Not Relate to the Obesity as a Risk Factor
Abstract: The duration of QT interval in the electrocardiograph record represents the ventricular repolarization. It is prolonged in women, ageing and using certain medications. In hypertensive patients, prolongation of QT interval is associated with cardiac risk factors and/or the complications of hypertension. This study aimed to measure the uncorrected (QT) and corrected (QTc) intervals using different formulas in overweight-obese patients with chronic hypertension. A total number of 25 healthy subjects and …

Remote Monitoring and Controlling of Digital Signage
Abstract: This paper is the design implementation and evaluation of a digital signage system based on a PC to display web contents (or other dynamic information) on digital displays located at one or more locations. The system will display information based upon a “playlist” that can be dynamically updated. It avoids the single point of failure of a display system, since each display has an attached processor and local storage containing …

ELECTROENCEPHALOGY (EEG) SIGNALS AND ITS EXPERIMENT DESIGN – A STUDY
Abstract: Human brain is a very complex structure of the whole body which actually contains millions of the neurons which are playing a vital role in controlling and maintaining the behaviour of the human body when we talk about the internal or external sensory stimuli. These neurons actually carry the message from the brain to body and body to brain. It acts as the messenger between the body and the brain. …

Real-time Sign Language Detection Using Computer Vision and Machine Learning Techniques
Abstract: Communication plays an important role in our day-to-day lives as it assists people in sharing, and connecting to each other. Despite knowing the significance of the same, some deaf-mute pupils who are not able to communicate freely. These groups of people use sign language for sharing their thoughts. It could be a tough task to understand sign language for a group of humans who are not deaf-mute. We developed a …

Sign Language Recognition Using Deep Learning
Abstract: People with hearing/speech disabilities use sign language to communicate their thoughts and feelings, but non-disabled people often find it hard to comprehend these hand gestures since they do not know sign language. This project aims to create a system that uses MediaPipe, LSTM and Keras for sign language recognition. The webcam will capture video footage of people performing sign language gestures, then MediaPipe will extract and identify the hand landmarks …

Introduction to Statistical Tests of Significance
Abstract: Hypothesis examination is the process in which we compare between two differing hypotheses. i.e. the null hypothesis H0 and the alternative hypothesis. As the null hypothesis is examined, a choice is either correct or incorrect. An incorrect conclusion can be produced in two methods: We can deny the null hypothesis once it is true (Type I error) or we cannot succeed to eliminate the null hypothesis when it is incorrect …

Human Deep Skin Surface Vibration Frequency Detection from CT and DT Signals Using Genetic Algorithms
Abstract: To diagnose respiratory problems early on, a contactless, non-invasive, real-time assessment of human vibration is a crucial prerequisite. Optoelectronic plethysmography (OEP) and the forced oscillation technique (FOT), are two widely utilized methodologies, depending on variations in each patient’s local chest impedance. Calibration of the devices before each measurement is hence the primary problem of these approaches. This report presents a simulation-based analysis to assess the effectiveness of the CT and …
