This document describes an IoT-based system for detecting and locating faults in underground cable lines. The system uses a potential divider network laid across underground cables to detect faults. When a fault occurs, it generates a specific voltage that is sensed by a microcontroller. The location of the fault is determined by the voltage and corresponding distance in the resistor network.

Design and ASIC Implemenatation of DUC/DDC for Communication Systems
Communication systems use the concept of transmitting information using the electrical distribution network as a communication channel. To enable the transmission data signal modulated on a carrier signal is superimposed on the electrical wires. Typical power lines are designed to handle 50/60 Hz of AC power signal; however they can carry the signals up to 500 KHz frequency. This work aims to aid transmission/reception of an audio signal in the spectrum from 300 Hz to 4000 Hz using PLCC on a tunable carrier frequency in the spectrum from 200 KHz to 500 KHz. For digital amplitude modulation the sampling rate of the carrier and the audio signal has to be matched. Tunable carrier generation can be achieved with Direct Digital Synthesizers at a desired sampling rate. DSP Sample rate conversion techniques are very useful to make the sampling circuits to work on their own sampling rates which are fine for the data/modulated-carrier signal’s bandwidth. This also simplifies the complexity of the sampling circuits. Digital Up Conversion (DUC) and Digital Down Conversion (DDC) are DSP sample rate conversion techniques which refer to increasing and decreasing the sampling rate of a signal respectively.
The objective was to design and implement low power ASIC of DUC and DDC designs at 65nm for PLCC. Low power implementation was carried out using Multi-VDD technique. MATLAB software models were used to understand the DUC and DDC designs. RTL to GDS flow was executed using Synopsys tools such as VCS, Design Compiler, IC Compiler and PrimeTime. Key milestones of this activity are RTL verification, synthesis, gate-level simulations, low power architecture definitions, physical implementation, ASIC signoff checks and postroute delay based simulations. Multi-VDD technique deployed on DUC and DDC helped to reduce the power consumption from 280.9uW to 198.07uW and from 176.26uW to 124.47uW respectively. DUC and DUC designs have met functionality at 64MHz clock frequency. Both the designs have passed postroute delay based simulations, static performance checks, power domain checks and TSMC’s 65nm design rule checks.

Using HPC to Advance Water Desalination By Electrodialysis
In this deck from the 2016 Stanford HPC Conference, Clara Druzgalski PhD, from Stanford University presents: Using HPC to Advance Water Desalination By Electrodialysis.
“Electrodialysis is a technology used for water purification in applications such as desalination for drinking water, waste water reuse, and demineralization. An electrodialysis system uses ion-selective membranes and applied electric fields to remove ions from aqueous electrolytes. High performance computing allows us to model the electrokinetic interactions that drive this process, providing insight on important underlying physics such as electroconvective chaos which has a significant effect on ionic transport and the prediction of mean quantities. Large scale simulations of this system provide a rich set of data enabling us to investigate phenomena such as the appearance of current density hotspots and the dominant spatial and temporal scales contributing to ionic transport through the membrane surface. In this talk I will discuss the development of the EKaos code: a parallel direct numerical simulation code for simulating chaotic electrokinetic transport. Results from large scale simulations using the EKaos code show qualitative agreement with experiments and improved quantitative prediction of statistical quantities.”

DIGITAL WAVE FORMULATION OF PEEC METHOD (SLIDES)
- The document presents a digital wave formulation of the partial element equivalent circuit (PEEC) method for quasi-static electromagnetic problems.
- It converts traditional PEEC networks into an equivalent digital wave network using scattering parameters and reflection-free ports. This allows for a more explicit solution scheme compared to matrix node analysis approaches.
- Numerical results on microstrip and multilayer structures show significant speed-ups of up to 627 times compared to traditional SPICE solvers when using the proposed digital wave PEEC approach.

This presentation shows a digital wave formulation
(DWF) of the quasi-static Partial Element Equivalent Circuit
formulation. Through the use of a pertinent change of variablesand the choice of a specific implementation of PEEC cell elementsin the Digital Wave domain, the standard PEEC model istransformed into and solved as a wave digital network. The
example reported shows the accuracy and the significant speedup up to 627X of the proposed DWF-based PEEC solver when compared to the standard Spice solution.

iaetsd Software defined am transmitter using vhdl
This document discusses the design and implementation of an amplitude modulation (AM) software defined radio transmitter using an FPGA. It begins with an abstract describing the goals of the project. It then provides an overview of the system design, including discussion of the individual components like the microphone, analog to digital converter, digital to analog converter, carrier frequency generator, and antenna. It describes how these components will be implemented on the FPGA, including using behavioral modeling with VHDL. It also discusses designing filters and modulation/demodulation circuits. The overall summary is that this document outlines the goals and high-level system design for creating an AM transmitter using an FPGA that can transmit an audio signal by digitally modulating a carrier frequency.
PC based Oscilloscope
The document describes a PC-based oscilloscope that can display input waveforms on a computer screen. It includes a block diagram of the circuit which conditions input signals below 1 kHz and converts them to digital format for interfacing with a PC. Software written in Turbo C acquires and displays the data. The PC-based oscilloscope costs less than traditional models, can store multiple waveforms, and allows viewing on multiple PCs over a network. However, it has limitations such as low input frequency and voltage range and lacks multi-channel capability.
Design and Detection of Underground Cable Fault Using Raspberry Pi and IoT Sy...
This document describes a proposed system to detect and locate faults in underground power cables using a Raspberry Pi and Internet of Things (IoT) technology. The system uses current transformers to measure changes in current caused by faults, which are then processed by a microcontroller to calculate the distance to the fault. The Raspberry Pi sends the fault details over the internet where they are displayed. The system aims to provide faster fault detection and more accessible fault information than existing methods. It works on the principle of current transformer theory and uses the Raspberry Pi's processing power and ability to connect to the internet to remotely monitor and locate underground cable faults.
Remote Control of Nanogrids: a Cost-effective Solution in a Laboratory Setup
This document summarizes a laboratory setup for remote control of nanogrids as a cost-effective solution. It describes how a nanogrid was prototyped to supply loads and connect to utility grid and storage. A single board computer remotely obtained setpoints from a database to control the power converter between the nanogrid and utility grid. The laboratory experiment demonstrated load curtailment to balance the nanogrid when battery levels dropped or PV generation turned off.
