A Fuzzy Logic-based Control System for Microwave Ovens

Conventional microwave ovens rely on users for their cooking time. In other words, the user must set the oven’s cooking time manually. This paper aims to design a fuzzy logicbased controller to resolve the above-mentioned issue by determining the cooking time of the microwave oven automatically. The time determined depends on the quantity and type of food. During the fuzzy logic process, we used the Mamdani fuzzy model. This model involves determining the crisp input, fuzzification, rule evaluation, and defuzzification, to obtain the crisp output result. Input real variables used were the type of food and quantity of food, whereas the output variable used was cooking time. A fuzzy logic toolbox on MATLAB software was used to design and simulate the whole system. Considering the IF-THEN rules and functions, we used the value of food as 50, and the type of food as 50 and we obtained the cooking time as 25 minutes. The result showed that Fuzzy models are good at determining cooking time in Microwave ovens and that their cooking time depends on the inputs. Using fuzzy logic in microwave ovens helps to maintain food quality, saves users’ time, and controls the energy used by the ove

Designing a conceptual framework of a smart city for sustainable development in Bangladesh

A smart city is a future solution to better management of the city and people. Recent researches have highlighted the necessity of smart city projects to improve urban lifestyle for the growing population. Bangladesh is one of the most densely populated countries in the world. Despite being a developing country, Bangladesh still lacks a smart city. A smart city framework is required to ameliorate urban lifestyle. The purpose of this study is to address a conceptual framework for a smart city project focusing on sustainable development in Bangladesh. The research approach follows an exhaustive literature review to collect suitable information to design the new smart city framework. Necessary information to design a smart city framework such as the core smart city dimensions and the sustainability indictors are identified through the thorough literature review. From the extracted information a new smart city framework is developed focusing on sustainable development. The findings of this study offer a clear overview of the smart city core dimensions and factors that influence sustainability in a smart city. The research presents a smart city framework that can be followed in a developing country like Bangladesh

DESAIN ARSITEKTUR SISTEM CERDAS BERBASIS IOT PADA BIDANG PERTANIAN PRESISI DI BANGLADESH

Pertanian di Bangladesh menjadi salah satu sektor produksi terbesar di kawasan Asia Selatan. Namun, dalam praktiknya para petani masih menerapkan metode pertanian tradisionnal. Hal ini dirasa tidaklah efisien untuk menghasilkan bahan pangan yang cukup untuk masa depan melihat populasi yang kian bertambah dari waktu ke waktu. Ada banyak ruang lingkup di bidang pertanian untuk dikembangkan di Bangladesh. Salah satu dengan menerapkan arsitektur sistem cerdas berbasis teknologi pada bidang pertanian presisi yang dapat memperlancar kegiatan pertanian tradisional. Penelitian ini bertujuan untuk memperkenalkan arsitektur sistem cerdas di bidang pertanian presisi berbasis IoT di Bangladesh. Metode yang diterapkan dalam penelitian ini menggabungkan beberapa sensor yang kompatibel dengan unit mikrokontroler, platform cloud IoT, dan aplikasi mobile. Sistem ini disimulasikan dalam perangkat lunak Cisco Packet Trace (Versi 7.3.1). Sensor mengumpulkan data lingkungan dari lapangan dan memprosesnya dalam platform cloud untuk menghasilkan informasi. Dan pada akhirnya Petani dapat mengakses informasi melalui aplikasi seluler dan membuat keputusan cerdas berdasarkan informasi untuk meningkatkan produksi tanaman. Sistem ini mendukung pemantauan dan pengendalian jarak jauh. Hasil simulasi menunjukkan bahwa sistem yang diusulkan dapat memantau faktor lingkungan dan memanipulasi berbagai status aktuator untuk menjaga lingkungan yang sesuai untuk tanaman
