Unmanned Aerial Vehicle (UAV) is inherently an unstable system and this necessitated the need of an external controller to stabilize and to control it. In this paper presents the exploration into the simulation, design and analysis of two autopilot schemes: (1) a fuzzy-PID controller and, (2) hybrid PID-Fuzzy controller for controlling pitch plane dynamics of an aircraft. The modeled fuzzy logi...

This paper presents an intelligent interpretation of ultrasonic C-scan results for carbon-fiber-reinforced plastic (CFRP) panels by using fuzzy logic approach. Ultrasonic C-scan results have relatively low resolution and poor imaging quality in anisotropic composites due to the speckle noise produced by the interference of backscattered signals. In this study, fuzzy logic was implemented to acc...

Despite significant advancements in wireless sensor networks (WSNs), energy conservation remains one of the most important research challenges. Researchers have investigated architectures and topologies that allow energy efficient operation of WSNs. One of the popular techniques in this regard is clustering. While many researchers have investigated cluster head selection, this paper investigate...

introduction: epilepsy is a clinical syndrome in which seizures have a tendency to recur. sodium valproate is the most effective drug in the treatment of all types of generalized seizures. finding the optimal dosage (the lowest effective dose) of sodium valproate is a real challenge to all neurologists. in this study, a new approach based on adaptive neuro-fuzzy inference system (anfis) was pre...

In this paper, the use of fuzzy inference system in criterion-referenced assessment was investigated. The aim of criterion-referenced assessment (CRA) was to report student achievement with reference to their objective reference points. To ease the assessment as in common practice, scores were given to each item or task. In this paper, we focus on CRA that utilizes rubric. Rubric is an essentia...

In this paper, a general approach is to classify of the green leaf healthiness. Fuzzy logic tool (FuzzyLite 3.2 software) and color features (RGB Spectrum) are used in this experiment. Mean values of primary colors (Red, Green and Blue) channels as input to FIS (Fuzzy Inference System). FIS gives decision whether this part of leaf is healthy, unhealthy or dying. Experimentation is conducted on ...

Prakiraan cuaca merupakan salah satu kajian yang sangat menarik untuk dilakukan. Data mengenai juga dibutuhkan di berbagai bidang kehidupan, sehingga membuat penulis tertantang meneliti metode paling akurat dalam memprakirakan cuaca. Salah teknik pemodelan prakiraan adalah Fuzzy Inference System (FIS), dan FIS ini menghasilkan tingkat akurasi tinggi.. Metode terbagi menjadi tiga tipe yaitu Mamd...
