Preservation of food and vegetable products is an age-old practice for the retention flavor, appearance, quality. From ancient times, driers drying grains work on direct sun rays, firewood, fossil fuels, coals causing carbon release. These available methods are expensive, unreliable, unhygienic; thereby use a solar dryer working free clean energy better higher value addition to preservation. Th...

If infiltration is uncontrolled and admits unconditioned air, the results will be undesirable. Controlling this problem increase thermal comfort decrease energy consumption. The aim of paper to assess performance different materials used improve airtightness, which efficiency. This research primarily adopted an experimental approach. A typical residential building in UAE was chosen as a case st...

PURPOSE To evaluate the effects of hydrogen peroxide pretreatment and heat activation of silane on the shear bond strength of fiber-reinforced composite posts to resin cement. MATERIALS AND METHODS The specimens were prepared to evaluate the bond strength of epoxy resin-based fiber posts (D.T. Light-Post) to dual-curing resin cement (RelyX U200). The specimens were divided into four groups (n...

BACKGROUND Several adverse consequences are caused by mild perioperative hypothermia. Maintaining normothermia with patient warming systems, today mostly with forced air (FA), has thus become a standard procedure during anesthesia. Recently, a polymer-based resistive patient warming system was developed. We compared the efficacy of a widely distributed FA system with the resistive-polymer (RP) ...

XRD1 was the first X-ray diffraction beamline to be built at the LNLS and after approximately 12 years of operation it was substantially updated to improve beam stability, increase the reliability of the monochromator movement as well as provide an experimental hutch that would meet the demands of users. The improvements included the construction of an independent concrete slab below the mirror...

The contribution of this paper is to provide a nonlinear MIMO scheme for a drying process, composed by four fuzzy controllers: Fuzzy Dehumidifier Controller (FDC-PD), Fuzzy Humidifier Controller (FHRC-PD), Fuzzy Electrical Resistance controller (FERC-PD) and Fuzzy Blower Controller (FBC-FD) and compare with results obtained previously with PID control scheme. The main aim is to allow the resear...
