This paper deals with hardware implementation of the robust sensor fault detection and accommodation system of F8 aircraft control system. Both detection and accommodation of normal acceleration sensor is done using two different models of neural network. The simulation model of the novel method of fault accommodation is tested for timing constraints in the embedded system target of ARM processor. Longitudinal plant dynamics of F8 aircraft model and C-Star controller is used for validation of neural network based sensor fault detection and accommodation (NNSFA) system. The robust sensor fault accommodation system is implemented on ARM target of Atmel SAM3X8E ARM Cortex-M3 CPU. This board is inbuilt with ADC and DAC ports to interface pilot input command and the display of the cockpit.

The concept of a hardware-in-the-loop method of implementing open-loop control of a three phase modular multilevel converter (MMC) using a cyclone II FPGA (field-programmable gate array) device on an Altera DE2 board is presented. Control signals are generated for the lower and upper level of each arm of the MMC by comparing reference signals with a carrier signal. This MMC topology employs a large number of switches depending on the number of levels needed in the output waveform. For its efficient operation, these switches need to operate as fast as possible and in parallel. Hence, an FPGA is a preferred choice for generating the switching signal. The analog-to-digital (ADC) pins of an arduino due micro-controller is used to interface the FPGA controller with the MMC and implemented in MATLAB/Simulink. The simulation and experimental results presented affirm the effectiveness of this open loop control implementation.

The traditional method of tea leaves harvesting is done in following ways, such as Hand Plucking using knife, Hand Plucking without using Knife. In the recent years the harvesting machines are introduced which can be operated by a single person or multiple persons and also a robotic vehicle. The challenges faced in the above systems are not enough capacity of human resources, intruding of wild animals into the fields, the machines don't have the intelligence on its own and also the robotic vehicle is terrain dependent which can be used only in the plain terrain. But the fields in India are irregular terrain. This paper proposed a semi-automatic system where the tea leaves will be harvested automatically by a robotic arm which will pluck the tea leaves based on the grade. The grade identification is done using the image processing techniques such as, Key Frame extraction, Rice counting, optical flow, and noise model with segmentation. The proposed work is novel because it has capabilities of considering motion with key frame capabilities and the noise model.

Subtractive and additive synthesis are two powerful sound synthesis techniques that caused a revolution when the first electronic and electro mechanic music instruments started to appear some decades ago. Subtractive synthesis became very popular during the 60s and 70s after the creation of analog hardware modules that could be interconnected, creating the concept of the modular synthesizers. After the initial impact, for some years these instruments faced a slow-down in its usage, a tendency that was reverted on the past decade. Nevertheless, the prices of these instruments are often high. Digital synthesizers also offer the subtractive synthesis technique, by using customized electronic components designed and developed by the synthesizers vendors in order to use the most up-to-date technologies and signal processing techniques, which also leads to high prices. In this project, we investigate the hypothesis that it is possible to design and develop a good quality music instrument with low budget electronic components and limited processing capabilities, by implementing this on a low budget and easy to use platform. The development is based on object oriented design, creating software modules that replicates the functionalities of analog synthesizer hardware modules. With this approach, we have a modular software that can be easily changed based on programmers’ preferences. The implementation was tested on the arduino due board, which is a cheap, easy to use and widely available platform and powered by a 32-bits ARM 84Mhz processor. We were able to add oscillators with anti-aliasing algorithms, filters, envelope generators, delay effects, a MIDI interface and a keybed, making a complete synthesizer. In addition to this, we included an additive synthesis organ design with full polyphony based on classic organs design, demonstrating the possibility of having two powerful synthesis methods on a cheap and widely available platform. With this design, suitable for low c

Development and programming of Geophonino: A low cost arduino-based seismic recorder for vertical geophones

COMPUTERS & GEOSCIENCES 2016年 94卷 1-10页

The commercial data acquisition systems used for seismic exploration are usually expensive equipment. In this work, a low cost data acquisition system (Geophonino) has been developed for recording seismic signals from a vertical geophone. The signal goes first through an instrumentation amplifier, INA155, which is suitable for low amplitude signals like the seismic noise, and an anti-aliasing filter based on the MAX7404 switched-capacitor filter. After that, the amplified and filtered signal is digitized and processed by arduino due and registered in an SD memory card. Geophonino is configured for continuous registering, where the sampling frequency, the amplitude gain and the registering time are user-defined. The complete prototype is an open source and open hardware system. It has been tested by comparing the registered signals with the ones obtained through different commercial data recording systems and different kind of geophones. The obtained results show good correlation between the tested measurements, presenting Geophonino as a low-cost alternative system for seismic data recording. (C) 2016 Elsevier Ltd.
