Induced fatigue has led to a large number of deviations of service failures in a wide range of applications, where the deterioration of properties occurs due to the slipping between surfaces at a small displacement. In this article, a numerical simulation of a semi-elliptical crack in the dovetail joint of the compressor was performed to understand the destruction of the blade due to the stress contour in the contact area. A three-dimensional crack is modelled using the ANSYS Finite Element Analysis program, and the blade profile is modelled by CATIA V5R20 software. The study considers a model of an open semi-elliptical crack, and the parameters of the movement of the crack tip are estimated using three-dimensional singular elements of the crack tip in ANSYS. Initially, a three-dimensional finite element model of a compressor blade with a dovetail contact area was simulated in CATIA V5 and analysed in the ANSYS working environment to determine the maximum principal stresses in the crack-free region. After the crack front has been precisely identified and confirmed, fracture modelling is used to determine the impact of crack size with one side, as well as rotation speed, on fracture parameters (stress intensity factors).

One of the measures from one's health is someone's heart wellbeing. Pulse rate monitoring could be used to determine heart conditions in contrast with using an ECG machine. That customer's high blood pressure requires regular heart rate management. In some circumstances, victims' health could be checked directly at such a medical facility. Digital vital signs monitor apps which can submit information in real-time are considered necessary for all of this. This article discusses the development of even a user interface that can instantly transmit blood pressure readings to the physician and health specialist via Short Messaging (SMS). That validity of a test then was shown by verification for detector data measured or SMS data output (systolic and diastolic). That processing period and pause among sending or receiving was 46.27 seconds for just a specific measurement based on the overall system test.

The most significant thing after the surgery in angle and leg, the incision part should be in immobilize state and shielding it from optional injury of thrashing around. That’s why individuals enthusiastically suggested this leg elevator. The leg elevator in this paper made of sugarcane bagasse. The sugarcane bagasse is a crude material which is of biodegradable. By using molding process the crude material made into a solid leg elevator. It is of minimal effort and sound contrasted with the current item made of synthetic substances. This is generally useful to recuperate rapidly from leg, point and thigh surgery. This paper proposes that sugarcane bagasse can be one of the elective crude materials which can be applied for bundling reason to decrease the ecological dangerous items in clinical supporting medium for leg.

This water management system enhances irrigated agriculture usage. We implemented an open loop fuzzy logic based scheme in this system. Inside the field, the inputs to the fuzzy logic system are modified from a pressure transducer, a temperature controller, and a flux sensor. The light and the water pump are the device's inputs. The simulation is performed with the aid of MATLAB and Simscape tools. The controller's control parameters and rule-based schemes are illustrated in the following sections of this study.

The Artificial intelligence (IoT) is indeed a technology that is used in a wide range of applications, like health monitoring. It makes it possible for human wellbeing integrity – to be hosted in the system, hospital stays for standard routine exams to be shortened, and, most importantly, wellbeing to be tracked and illness treated either by doctor anywhere at time. Detectors developed an IOT-based medical monitoring system which tracked body temp, breathing oximetry, and environment humidity and temperature, all of which have been shown through an LCD in the document. The above sensed data are then wirelessly transmitted to a healthcare provider. These data are then delivered to an approved personal smart phone compatible with an IOT platform. The specialist then diagnoses the disease and the patient's health status depending on the principles received.
