Agro-systems that avoid food decay and spoilage are required to extend produce shelf life. Driers remove food internal water, so dehydrated calyces can be stored without refrigeration for years. A roselle flower dehydrator with forced convection and air recirculation was tested in a high relative humidity environment. The constant circulation of dry hot air helped to maintain the air relative humidity below 28%. The equipment-controlled temperature at 55°C and dried calices in 7 hours. As several trays were used final calyx moisture homogeneity was analyzed and differences up to 2% obtained. After two years, stored calyces remained fungal-free and with excellent flavor. Solar indirect driers took 25 hours to dehydrate calices, as air temperature was not constant, and air relative humidity was always above 60%. Calyces’ moisture h..... ReadMore

In recent years, in the field of health, converting sign language information into written or spoken language has been proven to be an effective solution to the communication problems faced by deaf-mute individuals. However, achieving efficient and accurate gesture recognition still poses several challenges. These challenges include the diversity and individual differences in gestures, which require gesture recognition algorithms to possess strong universality...... ReadMore

Autonomous Underwater Vehicles (AUVs) are a highly suitable platform to investigate subsurface oil spills in the ocean. Adopting a dual driver system (sometimes known as a backseat driver) is now becoming almost standard practice since it enhances autonomy in the operation of the vehicle, thus increasing the achievement......
