Nowadays, renewable energy is becoming the most reliable way to generate electricity in exchange with non-renewable which commonly comes from coals and gases. This project about monitoring system of mini wind DC water pump application harvested seaside area. Thus, addresses development prototype by using Arduino UNO as main microcontroller. For development, voltage current sensors are used moni...

Water is one of the needs with remarkable significance to man and other living things. quality management a concept based on continuous monitoring water quality. The scheme aims accumulate data make decisions resource descriptions, identify real emergent issues involving pollution, formulate priorities, plan for management. regularly considered parameters when conducting are turbidity, pH, temp...

Abstract This paper proposes a low-cost portable interrogator for dynamic monitoring of wavelength-based fiber-optic sensors such as fiber Bragg gratings (FBGs) and Fabry-Perrot interferometers (FPIs). The is based on compact solution involving broadband light source the spectral convolution between sensor tunable filter. filtered signal then acquired by photodetector where optical-electrical c...

Wireless video communication over portable devices has become the driving technology of many important applications, experiencing dramatic market growth and promising revolutionary experiences in personal communication, gaming, entertainment, military, security, environment monitoring, and more. Portable devices are powered by batteries. Video encoding schemes are often computationally intensiv...

Post-traumatic stress disorders (PTSD) affect up to 20% of service members in the global war on terror. We use a portable multi-channel fNIRS device to assess student veterans with PTSD; preliminary results are reported. 2011 Optical Society of America OCIS codes: (170.1610) Clinical applications; (170.2655) Functional monitoring and imaging; (170.4580) Optical diagnostics for medicine;

Optical techniques are promising methods for measuring tissue temperature noninvasively due to the transparency of tissue to near infrared-light and the temperature dependent light-absorbing properties of endogenous absorbers, particularly water. Besides being noninvasive, the instruments are compact and portable, permitting bedside monitoring.

Micromachining technology is coupled to a selective pre-concentration material for the development of a portable sub-ppb level monitoring system for aromatic volatile organic compounds (VOC); the high sensitivity of Metal Oxide (MOX) gas sensors is combined with a supramolecular concentration unit to increase selectivity and reduce the detection limits.

STUDY OBJECTIVES Laboratory-based spirometry is the "gold standard" for the assessment of lung function, both in clinical and research protocols. These spirometers, however, are neither practical nor affordable for home-based monitoring or studies that collect data in multiple locations. Traditionally, peak flowmeters have been used, but they have important limitations. DESIGN Based on data f...
