This project presents the development of a "Smart Cat House" using Internet of Things (IoT) and image processing technology to facilitate and enhance the safety of cat care for owners. The infrastructure of the smart cat house consists of an ESP8266 board connected to an ESP32 CAM camera for cat monitoring, and an Arduino board that controls various sensors such as a motion sensor in the litter box, a DHT22 temperature and humidity sensor, an ultrasonic water and food level sensor, including a water supply system for cats, an automatic feeding system, and a ventilation system controlled by a DC FAN that adjusts its operation according to the measured temperature to maintain a suitable environment. There is also an IR sensor to detect the cat's entry into the litter box and an automatic sand changing system with a SERVO MOTOR. All systems are connected and controlled through the Blynk application, which can be used on mobile phones, allowing owners to monitor and care for their pets remotely. Cat detection and identification uses image processing technology from the ESP32 CAM camera in conjunction with YOLO (You Only Look Once), a high-performance object detection algorithm, to detect and distinguish between cats and people. Data from various sensors are sent to the Arduino board to control the operation of various devices in the smart cat house, such as turning lights on and off, automatically changing sand, adjusting temperature and humidity, feeding food and water at scheduled times, or ventilation. The use of a connection system via ESP8266 and the Blynk application makes it easy and convenient to control various devices. Owners can monitor and control the operation of the entire system from anywhere with internet access.
ในปัจจุบัน ผู้คนจำนวนมากเลือกเลี้ยงแมวเป็นเพื่อนคลายเหงา แต่ด้วยภาระหน้าที่การงาน การเรียน หรือธุระส่วนตัว ทำให้หลายครั้งเจ้าของไม่สามารถดูแลแมวได้อย่างใกล้ชิดตลอดเวลา ก่อให้เกิดความกังวลใจและเป็นห่วงสัตว์เลี้ยงที่บ้าน ปัญหาเหล่านี้เป็นแรงบันดาลใจให้เกิดแนวคิดในการพัฒนาบ้านแมวอัจฉริยะ (Smart Cat House) เพื่ออำนวยความสะดวกและตอบโจทย์ความต้องการของผู้เลี้ยงแมวในยุคปัจจุบัน บ้านแมวอัจฉริยะเป็นระบบที่ถูกออกแบบมาเพื่อช่วยให้เจ้าของสามารถติดตามและดูแลแมวได้จากระยะไกลผ่านแอปพลิเคชันบนมือถือ โดยภายในบ้านแมวอัจฉริยะจะมีระบบต่างๆ ที่ช่วยอำนวยความสะดวกสบายให้กับทั้งเจ้าของและแมว อาทิ ระบบควบคุมการให้อาหารและน้ำ ระบบจัดการกระบะทราย ระบบควบคุมอุณหภูมิ และระบบกล้องวงจรปิด เป็นต้น ทำให้บ้านแมวอัจฉริยะเป็นทางออกที่ตอบโจทย์สำหรับผู้เลี้ยงแมวที่ไม่ค่อยมีเวลา แต่ยังคงต้องการดูแลสัตว์เลี้ยงของตนให้มีความสุขและมีสุขภาพแข็งแรง

In this project, we introduce Power Grid Analyzer (PGAz), an open-source software package based on MATLAB, specifically designed for analyzing and controlling future power grids. Initially, PGAz is equipped with four fundamental features: power flow (PF), optimal power flow (OPF), small-signal stability analysis (SSSA), and time-domain simulation (TS). At this stage, Part I concentrates on the development of PF and OPF. The formats of our developed tool are presented, along with its command prompts. In this part, we have developed several conventional yet effective methods in the PGAz package to address PF and OPF problems, including techniques such as the Newton-Raphson method, Gauss-Seidel method, Interior Point Method, Iwamoto’s method, Fast Decoupled Load Flow, Genetic Algorithm, and Particle Swarm Optimization. Additionally, it emphasizes important aspects, algorithms, and various case studies that have been tested against IEEE benchmarks ranging from the IEEE 5-bus to the IEEE 300-bus test systems. The results demonstrate the capabilities of PGAz for future educational and research applications in PF and OPF. Finally, we outline a plan for developing Part II, which will mainly focus on SSSA and TS.

Microalgae are rich in bioactive compounds that may contribute to the growth of probiotics, which require appropriate nutrients, known as prebiotics, to thrive. This study aims to evaluate the effectiveness of crude extracts from intracellular components residues of the microalga Chlorella sp. KLSc61 in promoting the growth of the probiotic bacterium Lactiplantibacillus plantarum JCM1149 under simulated gastrointestinal conditions. The intracellular extracts were obtained using 70% (v/v) ethanol, and their effects on probiotic growth were tested at concentrations of 0.1%, 0.75% and 1.5%. The growth of Lactiplantibacillus plantarum JCM1149 was assessed using the drop plate method. The findings of this study will provide insights into the potential of Chlorella sp. KLSc61 extracts in enhancing probiotic growth, which could lead to the development of synbiotic dietary supplements containing both probiotics and prebiotics. Additionally, this study may serve as a foundation for further research on the role of microalgal extracts in gut health and immune system modulation.

The "PRIVARY" product is an innovative herbal jelly beverage designed to support weight management and promote health through the benefits of four Thai herbs: roselle, safflower, chrysanthemum, and bitter melon. These herbs are rich in active compounds such as flavonoids, beta-carotene, and anthocyanins, which help reduce blood lipids, prevent inflammation, and exhibit antioxidant properties. The product emphasizes convenience and caters to health-conscious consumers using advanced production techniques like Inverse and External Gelation to create spheres encapsulating key bioactive compounds. Additionally, the product aligns with sustainability goals by enhancing the value of Thai herbs and supporting local communities.
