Este estudo, realizado nas condições do Cerrado do Planalto Central, teve porobjetivo avaliar o efeito da época de suspensão das irrigações por aspersão naprodução, qualidade de frutos e uso de água do tomateiro para processamento. Ostratamentos consistiram de quatorze épocas de suspensão, espaçadas de 7 dias,desde o florescimento até a colheita. A maior produtividade de frutos foi obtidaquando as irrigações fo...
This paper describes the fabrication process of thermoelectric microconverters, based on n-type bismuth telluride (Bi2Te3) and p-type antimony telluride (Sb2Te3) thin films. Materials are fabricated by thermal co-evaporation with thermoelectric properties comparable to those reported for the same materials in bulk form (used in conventional macro-scale Peltier modules). Absolute value of Seebeck coefficient in ...
This paper describes the development of wireless sensor network prototype that gathers biometrical data and posture information from several wearable sensor networks and sends it in real-time to a personal computer where the information is monitored and stored. The wireless sensor network is based on a low power real-time MAC protocol that was designed and implemented in the MICAz platform. This paper also pres...
A wireless smart-suit network for monitoring body kinetics, heart and respiratory rate during hidrocinesiotherapy sessions is presented. Sensing modules composed by 3-axis accelerometers, 3-axis magnetometers and interface electronics are used to monitor the body kinetics. Heart rate is measured using an ear clip infrared sensor and respiratory frequency is measured with inductance plethysmography. The sensor n...
