Design and Implementation of a GPS based Personal Tracking SystemSudhanshu Janwadkar
Design and Implementation of a GPS based Personal Tracking System
Tracking based applications have been quite popular in recent times. Most of them have been limited to commercial applications such as vehicular tracking (e.g tracking of a train etc). However, not much work has been done towards design of a personal tracking system. Our Research work is an attempt to design such personal tracking system. In this paper, we have shared glimpses of our research work.
The objective of our research project is to design & develop a system which is capable of tracking and monitoring a person, object or any other asset of importance (called as target). The system uses GPS to determine the exact position of the target. The target is aided with a compact handheld device which consists of a GPS receiver and GSM modem. GPS receiver obtains location coordinates (viz. Latitude & Longitude) from GPS satellites. The location information in NMEA format is decoded, formatted and sent to control station, through a GSM modem. Due to use of Open CPU development platform, no external Microcontroller is required, with additional advantage of compact size product, reduced design & development time and reduced cost.
Thus, the proposed system is able to track the accurate location of target. This system finds applications in tracking old-age people, tracking animals in forest, tracking delivery of goods etc. Our final designed system is a small-size compact l.S"X3.7S" Tracker system with position accuracy error <30m (100 feet).
With advancement in CMOS technology, a lot of research has been done to develop various logic styles to improve the performance of logic circuits. D flip-flops (DFF) are fundamental building blocks in almost every sequential logic circuit. Hence, in sequential logic circuits, the overall performance of the circuit is affected by the performance of constituent DFFs. In recent years, the focus has been towards incorporating higher clock rates in a processor for better performance. To achieve high clock rates, fine granularity pipelining techniques are used, which implies that there are relatively a fewer levels of logic in each pipeline stage. A major consequence of this design trend is that the pipeline overhead has becoming more significant. The primary cause of pipeline overhead is the latency of the flip-flop or latch used to design the processor and the clock skew of the system. This calls out for the need of incorporating the logic functionality within the architecture of flip-flop. The new family of flip-flops are called Embedded Logic Flip Flops. In this Paper, we have reviewed various Flip-flop architectures which have been proposed so far. Our attempt is to do a qualitative analysis and comparison of the proposed Embedded logic flip-flop designs.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

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.
