This paper proposes an analytical design procedure for 2D FIR circular filter banks and also a novel, computationally efficient implementation of the designed filter bank based on a polyphase structure and a block filtering approach.The component filters of the bank are designed in the frequency domain using a specific frequency transformation appl
In hypergolics two substances ignite spontaneously upon contact without external aid.Although the concept mostly applies to rocket fuels and propellants, it is only recently that hypergolics has been recognized from our group as a radically new methodology towards carbon materials synthesis.Comparatively to other preparative methods, hypergolics al
Kegiatan penambangan minyak bumi tidak hanya dilakukan oleh perusahaan-perusahaan besar, tetapi juga oleh masyarakat secara tradisional.Potensi pencemaran lingkungan yang ditimbulkan oleh kegiatan penambangan rakyat ini menjadi lebih tinggi karena pengelolaannya yang tradisional.Salah satu jenis pencemaran yang ditimbulkannya misalnya adalah tanah
An experimental and numerical study was carried out to investigate heat transfer and flow characteristics through the tractor heat exchanger (radiator).The engine of the tractor is Diesel (compression ignition) engine type.The experimental study used heat exchanger (radiator) manufactured from copper instead of the original heat exchanger of the tr
Background: copyright dependent individuals (CDI) present executive cognitive function (ECF) deficits, but the impact of psychiatric comorbidities such as Attention-Deficit Hyperactivity Disorder (ADHD) on neuropsychological functioning is still poorly understood.The aim of this study was Lamp/Light to investigate if CDI with ADHD (CDI+ADHD) would
