Development and Application of a Failure Monitoring System by Using the Vibra...inventy
In this project, a failure monitoring system is developed by using the vibration and location information of balises in railway signaling. A lot of field equipment in railway are loosening and broken in time period so that they need maintenance due to the vibrations that occur due to high speed trains traffic and railway vehicles impact. Among the field equipment, balises have very important role of communication in terms of transmitting information to trains. In this scope, it is aimed to make maintenance works more efficient, have no delayed trains, detect previously failure location and intervene in failure timely, by detecting and controlling balise cases such as loosening, out of place and the data consistency error that happens because of balise physical state. In this project, the communication is provided with I2C, Modbus RTU (Remote Terminal Unit) and RS485 standards by using Arduino Uno cards and MPU6050 IMU (Inertial Measurement Unit) sensors in laboratory. Each used sensors are in slave mode and computer interface designed with C# is in master mode. Fault situations in the system are checked instant by the interface. (it is assumed to mount the IMU sensor and the Arduino circuit on the balise) it is seen that the interface responds to the sensor movements instant and the system works well in the end of test processes.
This session combines the high speed analog signal chain from RF to baseband with FPGA-based digital signal processing for wireless communications. Topics include the high speed analog signal chain, direct conversion radio architecture, the high speed data converter interface, and FPGA-based digital signal processing for software-defined radio. The demo board uses the latest generation of Analog Devices’ high speed data converters, RF, and clocking devices, along with the Xilinx Zynq-7000 SoC. Other topics of discussion include the imperfections introduced by the modulator/demodulator with particular focus on the effect of temperature and frequency changes. In-factory and in-field algorithms that reduce the effect of these imperfections, with particular emphasis on the efficacy of in-factory set-and-forget algorithms, are examined.

Design of an IOT based Online Monitoring Digital StethoscopeIJAAS Team
Acoustic stethoscopes have low sound levels. Digital stethoscope overcomes this issue by amplifying body sounds electronically. As the sound signals are transmitted electronically, it can be wireless and can provide noise reduction. Acoustic stethoscope can be changed into a digital stethoscope by inserting an electric capacity microphone onto its head. Heart sounds received from the microphone are processed, sampled and sound signals are converted analog to digital and sent wirelessly using the Internet of Things(IOT) techniques, so that multiple doctors can do auscultation and monitor conditions of the patient.

Implementation of Algorithms For Multi-Channel Digital Monitoring ReceiverIOSR Journals
Abstract: Monitoring Receivers form an important constituent of the Electronic support. In Monitoring
Receiver we can monitor, demodulate or scan the multiple channels.
In this project, the Implementation of algorithm for multi channel digital monitoring receiver. The
implementation will carry out the channelization by the way of Digital down Converters (DDCs) and Digital
Base band Demodulation. The Intermediate Frequency (IF) at 10.7 MHz will be digitalized using Analog to
Digital Converter (ADC) with sampling frequency 52.5 MHz and further converted to Base band using DDCs.
Virtually all the digital receivers perform channel access using a DDC. The Base band data will be streamed to
the appropriate demodulators. Matlab Simulink will be used to simulate the logic modules before the
implementation. This system will be prototyped on an FPGA based COTS (Commercial-off-the-shelf)
development board. Xilinx System Generator will be used for the implementation of the algorithms.
Keywords: DDC, ADC, Digital Base band demodulation, IF, Monitoring Receiver.
The numerically controlled oscillator (NCO) is one of the digital oscillator
signal generators. It can generate the clocked, synchronous, discrete
waveform, and generally sinusoidal. Often NCOs care utilized in the
combinations of digital to analog converter (DAC) at the outputs for creating
direct digital synthesizer (DDS). The network on chips (NOCs) are utilized
in various communication systems that are fully digital or mixed signals
such as synthesis of arbitrary wave, precise control for sonar systems or
phased array radar, digital down/up converters, all the digital phase locked
loops (PLLs) for cellular and personal communication system (PCS) base
stations and drivers for acoustic or optical transmissions and multilevel
phase shift keying/frequency shift keying (PSK/FSK) modulators or
demodulators (modem). The basic architecture of NCO will be enhanced
and improved with less hardware for facilitating complete system level
support to various sorts of modulation with minimum FPGA resources. In
this paper design and memory optimization of hybrid gate diffusion input
(GDI) numerically controlled oscillator based on field programmable gate
array (FPGA) is implemented. compared with NCO based 8-bit microchip,
memory optimization of hybrid GDI numerically controlled oscillator based
on FPGA gives effective outcome in terms of delay, metal-oxidesemiconductor field-effect transistors (MOSFET’s) and nodes.

Architecture of direct_digital_synthesizanjunarayanan
A frequency synthesizer is an electronic device which generates a range of frequency mostly sine wave from a fixed clock provided. These frequency synthesizers are commonly found in radio receivers, mobile telephones radio telephones, wacky talkies, as local oscillators, satellite receivers, GPS system. Direct digital synthesizer is a frequency synthesizer which digitally creates arbitrary wave forms of different frequencies from the fixed frequency provided as clock input.DDS generates digital wave forms and these digital waveforms are converted to analog signals by the digital to analog converter connected at the output of DDS. The DDS designed here is a ROM based DDS. DDS has many advantages over PLL and other similar approaches such as fast settling time, sub-Hertz frequency resolution, continuous phase switching response and low phase noise. This system has many applications such as the confidential message transfer, speedy frequency switching.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
