This document summarizes a study that evaluated the performance of asphalt binders and mixtures containing sugarcane waste molasses. Various percentages of molasses (5%, 10%, 15%, 20%) were added to replace the base asphalt binder. Traditional tests were used to evaluate the modified binders' characteristics. Marshall stability and indirect tensile strength tests were conducted on asphalt mixtures containing the modified binders. The results showed that sugarcane molasses improved moisture damage resistance and Marshall properties at 10% replacement. The optimum molasses content found was 10% of the base asphalt weight based on the laboratory tests.
Laboratory Investigation of Conventional Asphalt Mix Using Shell Thiopave for...IJERA Editor
The characteristic performance of asphalt pavement always depends on the properties of bitumen, volumetric properties of asphalt mixtures. Bitumen is visco– elastic material where the temperature and rate of load application have a great influence on its behavior. There are different solutions to reduce the pavement distress such as using Thiopave (binder extender and asphalt mixture modifier) in the mix design. Thiopave can significantly alter the performance properties of the mix and it is helpful to extend the life span of pavement. In this study, investigating use of thiopave and the change in the performance properties is dependent both on the percentage of virgin binder using VG-30 bitumen that is substituted with thiopave with different percentages. The study indicated that 10%, 20%, 30% and 40% replacement of binder was done with thiopave. The most notable impact of the addition of thiopave to a bituminous mixture is an increase in the stiffness of the mixture for better resistance to fatigue cracking and rutting. Thiopave materials can have a positive impact on laboratory mixture performance. The addition of thiopave has been shown to significantly increase Marshall Stability. From this study it is observed that thiopave can be utilized up to 30% to 40% as replacement to bitumen.

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.

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.
