A workstation that runs quietly and cooly and uses less power is a great boon to workers and the companies they work for. In our tests, both when idle and when under load, the Lenovo ThinkStation D30 generally ran at lower surface temperatures than the HP Z820 Workstation and ran more quietly. The Lenovo ThinkStation D30 also used less power when idle and while under load. These findings show that the Lenovo ThinkStation D30 could meet the needs of those who want to provide a reliable, comfortable work environment while using less power.
Abstract To develop a home heating system with high efficiency, the outdoor temperature is not the only parameter to be considered but also disturbances such as ventilation, door/window openings and personal lifestyle. The aim of the project is to develop the home heating system which adapts itself to changing customer demands using fuzzy logic. The energy consumption and the outdoor temperature of the house were monitored over a period of one year to produce the data required to program the fuzzy controller and thereby the appropriate set temperature will be determined. When load disturbances such as door/window openings are given, there is an increase in the energy required by the heater. This additional energy is obtained as an output from the fuzzy controller and given to the heating system. The design, optimization and implementation of the fuzzy controller are supported by LabVIEW software

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.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

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.

Place laptop on box, and power it on.
The system works best if the laptop is as cool as
possible at the start.
Place the system so that the temperature sensor is positioned
in front of the exhaust port of the laptop.
Plug PSoC into a USB port, and plug the fan into the power
supply.
Program the PSoC and power it.
LCD will display the temperature of the exhaust and the
current fan setting. The current fan setting will also be
displayed using the LEDs.
Begin operating the computer as desired, including any
high-load operations.
As the computer heats up, the system will increase the
fan speed to the next setting if the temperature rises
above 120 °F. It will then wait 30 seconds before
checking the temperature again. If the fan reaches the
highest setting, a buzzer will turn on to warn the user
that the fan is unable to keep the laptop cool.
When finished with the high-load operations, allow the
computer to cool down.
As the computer cools, the system should decrease the
fan speed if the temperature drops below 110 °F.
We designed a system that uses a temperature sensor to measure the temperature of a computer’s exhaust and uses that information to adjust the speed of a fan to
cool the laptop.
For many engineering students that run powerful software on their laptops, it is important to keep their computers well maintained to avoid needlessly shortening their
laptop’s life span. A common issue is overheating. When a laptop is exerting a lot of its processing power, the internal temperature of the computer increases, which
can cause the computer to crash or possibly experience hardware damage. While this is typically avoidable from a software perspective, it is much less avoidable
when the user needs to work with powerful software that demand a lot of processing power from their computer. To protect a laptop from overheating and ultimately
shortening its working lifetime, a supplemental external cooling fan can be used. However, overuse of a fan can cause unnecessary wear. Additionally, an external
fan is louder and uses more power at higher speeds. Therefore, it is beneficial to have a system that determines the minimum speed the fan needs to run at to keep
the computer cool.
