Abstract

Pengenalan Emosi Wajah telah lama menjadi topik hangat dalam penelitian identifikasi pola komputer, dan saat ini tidak ada metode pengenalan ekspresi wajah yang memiliki tingkat pengenalan 100%. Jadi, meningkatkan tingkat pengenalan memerlukan pra-pemrosesan set data yang lebih baik, meningkatkan pendekatan ekstraksi fitur, dan memanfaatkan pengklasifikasi terbaik untuk pengenalan wajah. Penelitian ini bertujuan untuk meningkatkan pendekatan ekstraksi ciri untuk meningkatkan tingkat pengenalan sistem pengenalan ekspresi wajah. Fase penting dalam pengenalan gerakan wajah adalah ekstraksi fitur, yang menentukan tingkat pengenalan. Fitur harus diekstraksi dengan cara atau proyeksi yang berbeda untuk meningkatkan tingkat pengenalan, tetapi ada risiko mengembangkan redundansi, yang akan menurunkan tingkat pengenalan. Sementara Gabor memiliki varian fitur yang maksimal, ia memiliki kesulitan dengan dimensi dan redundansi yang tinggi. Beberapa strategi harus digunakan untuk mengurangi ukuran dan redundansi. Filtering adalah teknik pengurangan dimensi yang digunakan oleh Gabor. Oleh karena itu seluruh proses dikenal sebagai filter Gabor. Pengambilan sampel, pemfilteran rata-rata, dan teknik pemfilteran lainnya adalah contohnya. Fitur-fitur Gabor difilter menggunakan transformasi wavelet dan mendapatkan komponen optimal dari dataset wajah dalam teknik ekstraksi fitur Gabor yang diusulkan, memberikan tingkat pengenalan yang lebih tinggi daripada teknik ekstraksi fitur Gabor rata-rata dan teknik ekstraksi fitur penyaringan Gabor sampling pengenalan ekspresi wajah.

Abstract

Memanfaatkan mobilitas beberapa komponen jaringan baru-baru ini dilaporkan sebagai salah satu pendekatan yang paling menjanjikan untuk meningkatkan kinerja jaringan sensor nirkabel (WSN) dalam hal metrik penting seperti masa pakai dan latensi data. Teknik Pergerakan Node Terkendali Berbasis Energi diusulkan dalam penelitian ini untuk mengatur mobilitas node sensor (EBCNM). EBCNM mencoba untuk menggeser node untuk mencapai keseimbangan energi dan beban di seluruh node, memperpanjang masa pakai jaringan. Menggunakan simulator jaringan NS2, kinerja EBCNM diuji dan dibandingkan dengan node statis dan gerakan node acak. Hasilnya menunjukkan peningkatan masa pakai jaringan sebesar 31 persen hingga 120 persen dan peningkatan rasio pengiriman paket sebesar 43 persen hingga 115 persen.

Abstract

When motorcyclists have an accident, they are at high risk of suffering severe or fatal injuries. The difficulty experienced by motorcyclists and considered one of the most complicated to do in an emergency is braking because motorcycle accidents are often caused by loss of control or stability when braking as evasive action. In the braking process, a motorcycle must pay attention to distance and speed so that the deceleration during braking is by the kinematic concept to avoid the shock force during braking, in this study uses research and development methods in making automatic braking systems on motorbikes. The actuator system controls the brake pedal, and the gas pedal uses a stepper motor. The two stepper motors will move automatically if the motorbike detects an object in front of it at less than 4 meters. The angle of the stepper motor that drives the brake lever is in a span between 0 degrees to 30 degrees, while the tip of motion of the stepper motor that moves the gas pedal is in a span of 0 degrees to 70 degrees. The angle movement of the stepper motor is influenced by the distance detected by the HC-SR04 type proximity sensor and the motorbike speed detected by the KY-003 type speed sensor, which works by utilizing the hall effect principle. The results of the tests that have been carried out show that the automatic braking system created can work well with an indicator that there is no shock force during the automatic braking process

Abstract

Image segmentation is very important in the approach of image analysis to learn about any image. The K-means clustering technique is an algorithm widely used in image segmentation systems. This work utilizes the Lab* color space and K-means clustering to offer color-based image segmentation. This research demonstrates image segmentation of a database based on color characteristics using unsupervised K-means clustering technique implemented with MATLAB coding. The entire work is divided into two phases. Firstly, color separation augmentation from the color image database is enhanced through de-correlation stretching. Then, the six areas of the image database are clustered into three groups using the K-means clustering technique. By using the Lab* color space and K-means clustering method in the color image database, we can only show the central area of any image. We can isolate contaminated areas in medical color image databases with this approach and treat diseases quickly. We can use various approaches such as Particle swarm Optimization (PSO) for better results.

Abstract

Utilizing clean and renewable energy is crucial for progress and development. Reducing carbon emissions is the goal of using this renewable energy, resulting in a clean and healthy environment. With only a tiny CO2 emission of 20.32% or CO2 emissions reduced by up to 79.69%, solar energy is regarded as one of the most environmentally friendly renewable energy sources. The method used in this study is to simulate the creation of PLTS with the HelioScope web application with a design project for the Kadudampit sub-district office, Sukabumi district. The results of this study are that with the use of new renewable energy (EBT) for solar power plants (PLTS), the monthly energy production obtained is relatively stable, with yields ranging from 1,041.5 kWh - 1,568.1 kWh, and the annual energy production got is 14,853.7 kWh.
