The MIata required a larger diameter pulley in order to reduce the speed of the alternator relative to the crankshaft. With the engine operating at higher rpms for most of the on track time, we did not want to over charge the electrical system.
Video analysis showed that the inside tire was lifting during hard cornering. Symptoms were mid corner and exit understeer.
This led to research to determine the roll rate of the rear suspension through vehicle dynamics and spring rate calculations. Then, commercially available rear anti roll bars (ARB) were assessed and their spring rates calculated and compared to custom original designs.
In the end, due to lack of manufacturing ability and time, the commercially available rear ARB was purchased and installed.
Results: mid corner understeer corrected, exit understeer improved, vehicle cannot lift inside front tire.
Original radiator design to accommodate a change in the coolant routing in the engine. This design also allowed the engine to be over cooled, thereby allowing the use of water restrictors and tape on the grill to calibrate energy transfer rates for given atmospheric conditions.

A quick presentation put together to inform students what kind of projects they should expect, how the class operates, when and where the class meets and other general info.
This study was performed to determine the projected cost of developing the programs MGB race to a prep level of F Production for competition in SCCA Club Racing.
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.

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.
