Strengthening of prism beam by using NSM technique with roots planted in concrete

This paper presents experimental results of four prismatic concrete reinforced beam and strengthened by NSM (Near surface mounted) FRP (Fiber Reinforced Polymer) reinforced technique, with additional roots planted in the concrete. The strengthening technique causes load capacity of beams to increase from (6%-8%).A decrease in mid-span deflection was also observed from (4%-5%).Using this technique gave increasing in flexural beam resistant under the same conditions and this increasing was also noted in shear beam resistant

Design and development of wireless stethoscope with data logging functions

Stethoscope is a special device to hear heartbeat sound and monitor pulmonary disease. The most type of stethoscope used these days is the acoustic stethoscope. However, the problem with this acoustic stethoscope is the sound level very low. It is hard to analyze the heart sound and difficult to be diagnosed by a medical doctor. Therefore, this project was developed to monitor and display heartbeat sound using wireless digital stethoscope. The condenser microphone is used as a sensor to capture the low sensitivity of heart sound signal and transmit the signal using Antenna Arduino ZigBee Pro Series 1. Microcontroller Arduino Nano and Arduino Mega were used as a platform to process the signal and sent the result to the computer. Graphical User Interface (GUI) was developed using MATLAB software to monitor real time electrocardiogram (ECG) waveform and for data logging purpose. The result shows that this device able to transmit and receive ECG waveform wirelessly. The ECG signal can be recorded through data logging application for further analysis by the medical personnel

A Wireless Emergency Telemedicine System for Patients Monitoring and Diagnosis

Recently, remote healthcare systems have received increasing attention in the last decade, explaining why intelligent systems with physiology signal monitoring for e-health care are an emerging area of development. Therefore, this study adopts a system which includes continuous collection and evaluation of multiple vital signs, long-term healthcare, and a cellular connection to a medical center in emergency case and it transfers all acquired raw data by the internet in normal case. The proposed system can continuously acquire four different physiological signs, for example, ECG, SpO2, temperature, and blood pressure and further relayed them to an intelligent data analysis scheme to diagnose abnormal pulses for exploring potential chronic diseases. The proposed system also has a friendly web-based interface for medical staff to observe immediate pulse signals for remote treatment. Once abnormal event happened or the request to real-time display vital signs is confirmed, all physiological signs will be immediately transmitted to remote medical server through both cellular networks and internet. Also data can be transmitted to a family member’s mobile phone or doctor’s phone through GPRS. A prototype of such system has been successfully developed and implemented, which will offer high standard of healthcare with a major reduction in cost for our society

Sistema para el apoyo a la atención domiciliaria mediante redes de sensores inteligentes

RESUMEN: El incremento de pacientes con enfermedades crónicas y los costos asociados a su tratamiento representan un serio problema para los diferentes sistemas de salud a nivel mundial. Este tipo de pacientes son recurrentes a los hospitales y centros de salud causando congestión y altos costos asociados a la atención médica. Las nuevas tendencias tecnológicas podrían ayudar en la implementación de sistemas de información que puedan brindar apoyo a los médicos en el cuidado de pacientes crónicos en ambientes domiciliarios. Un ejemplo de estas tendencias tecnológicas son las redes inalámbricas de área corporal WBAN (Wireless Body Area Network). Esta tecnología emergente promete brindar una ayuda en el desarrollo de aplicaciones de cuidado médico en el hogar. La tecnología WBAN se encuentra aún en una etapa temprana y requiere de trabajo e investigación para poder impulsar un cambio de paradigma en la atención médica, pasando del hospital al hogar del paciente. Este trabajo de investigación presenta el diseño de un nodo sensor inalámbrico basado en la tecnología WBAN y orientado a apoyar la atención de pacientes crónicos. Se presenta el diseño completo del nodo sensor y la evaluación del prototipo funcional. El proceso de diseño se basó en técnicas innovadoras de co-creación que llevaron a la implementación de un prototipo funcional. Los requerimientos del sistema, el prototipo conceptual y el prototipo final fueron obtenidos de este proceso de diseño. El prototipo funcional se evaluó en términos de consumo energético, latencia y pérdida de paquetes. Los resultados muestran que el sistema diseñado representa un buen punto de partida para potenciales aplicaciones de cuidado médico de pacientes crónicos en ambientes domiciliarios

Body sensor network for in-home personal healthcare

A body sensor network solution for personal healthcare under an indoor environment is developed. The system is capable of logging the physiological signals of human beings, tracking the orientations of human body, and monitoring the environmental attributes, which covers all necessary information for the personal healthcare in an indoor environment. The major three chapters of this dissertation contain three subsystems in this work, each corresponding to one subsystem: BioLogger, PAMS and CosNet. Each chapter covers the background and motivation of the subsystem, the related theory, the hardware/software design, and the evaluation of the prototype’s performance
