Cooling suit with two-phase flow heat-exchange system

Cooling suit with two-phase flow heat-exchange system

Abstract

Cooling suit with two-phase flow heat-exchange system is a state-of-the-art heat sink, designed for thermal dissipation in fire fighter, racing driver and worker who needs to wear Personal Protective Equipment (PPE). The liquid cooling system with gas injection can enhance heat transfer performance and continuously maintain the temperature at 18-20 degree Celsius.

Astaxanthin-rich Oil Extracted with Ultrasound Assisted-Natural Deep Eutectic Solvent from the Byproduct of Black Tiger Shrimp (Panaeus monodon).

The study investigated the extraction of astaxanthin-rich oil from shrimp waste biomass, a valuable byproduct rich in functional lipids and proteins. Wet rendering has long been an inexpensive method to extract oil, however the high temperatures and long cooking times negatively affect the amount of astaxanthin. On the other hand, the study looked into employing deep eutectic solvent as a green solvent and combining a wet rendering process with high-shear homogenization and high-frequency ultrasound-assisted extractions. DES-UAE at 60% amplitude and wet rendering at 60 °C were found to be the ideal conditions, as were DES-HAE at 13,000 rpm and wet rendering at 60 °C. With a notable increase in oil yields of 16.80% and 20.12%, respectively, and improved oil quality (lower acid and peroxide values) in comparison to the conventional wet rendering, experimental validation validated the effectiveness of the DES-HAE and DES-UAE procedures. DES-UAE notably raised the amount of astaxanthin. This study demonstrates that DES-HAE and DES-UAE are quicker, lower-temperature substitutes for obtaining premium, astaxanthin-rich shrimp oil, resulting in more effective use of this priceless byproduct.

Flow of Humane

This piece represents the collection of all human elements, applied to design for maximum efficiency, following the principles of Modern designers who embraced the famous phrase "Form follows Function." Every line and structure of the design is carefully considered for user comfort and practical use, while reflecting the idea that the user's experience is central to the design process. The beauty emerges from the harmony between function and form, not only meeting functional needs but also enhancing the aesthetic of Modernist design in a complete and meaningful way.

Web Application for Shrimp Feed Transportation Route Optimization: A Case Study of an Animal Feed Store

Efficient logistics management requires the development of advanced tools to streamline delivery operations. This study aims to optimize vehicle routes for an animal feed store and develop a web-based application for route planning. The research compares two optimization methods: the Branch and Bound Method and Clustering with the Branch and Bound Method. These methods are evaluated against the store’s existing delivery route by analyzing differences in average travel distance across three dependent groups using Repeated Measures ANOVA. The findings reveal a statistically significant difference in average daily travel distances among the three methods at a 0.05 significance level. The Branch and Bound Method yields the shortest average daily travel distance. Additionally, pairwise comparisons of total daily travel distances using the Paired t-test confirm that the Branch and Bound Method produces the most efficient route with statistical significance at 0.05 level. Implementing this method can reduce total travel distance by 957.51, representing a 30.88% reduction, which translates into fuel cost savings of 2,579.45 THB per month. Based on these results, the Branch and Bound Method was selected for implementation in a web-based application. The application features an intuitive user interface, product inventory management, and optimized daily delivery route recommendations for the case study store. Following development, the web application was deployed and tested in real-world operations. The results demonstrate that it effectively provides map-based route recommendations, ensuring ease of use and accessibility on standard mobile devices.
