This document summarizes a literature review on 3D printed concrete. It discusses the objectives of studying interlayer bonding strength in 3D printed concrete structures and reducing alkali-silica reaction (ASR). The literature review covers topics like the effect of time gaps between printed layers on bonding strength, modeling fresh self-consolidating concrete flow, and using recycled sand in 3D printed concrete mixes. It also examines prior research on predicting concrete properties with artificial neural networks, improving buildability and early strength with nanoclay additives, and using viscosity modifying admixtures like polyacrylamide and polyvinyl alcohol fibers in printable concrete mixes.

This document summarizes research on 3D network-on-chip architectures. It begins by introducing the benefits of 3D integrated circuits for reducing wire lengths and improving performance. It then surveys several existing 3D NoC architectures:
1) Symmetric NoC which treats intra-layer and inter-layer hops identically, incurring high overhead.
2) NoC-Bus Hybrid which uses a bus for single-hop vertical links to reduce hops.
3) Ciliated 3D Mesh which restricts switches to layers and adds cores per switch, lowering bandwidth.
4) True 3D NoC Router which embeds vertical links directly in crossbars for seamless routing.
The
QD to NH; Mathematical Modelling of Nano-structure Formations
Mathematical formulation is given to the formations of the nano-structures created by DE (Droplet Epitaxy) for
quantum – circuit application. Many of the known (and yet unknown) formations are derived from the two basic
elements of nano-structures, namely the QD (Quantum Dot) and the NH (Nano Hole). Combined formations of the
two shapes model the formations of the ones already used for circuit applications and predicts new nano-shapes for
possible future usage such as meta materials. Their parameters are close related to the experimental conditions used
at productions stage.

Rapid prototyping (RP) uses additive manufacturing techniques to quickly produce physical prototypes directly from 3D CAD models. There are several RP technologies categorized by the form of the starting material - liquid, solid or powder. RP allows faster prototyping compared to traditional methods and is useful for design validation, engineering analysis, tooling applications and small batch manufacturing. However, RP parts can have reduced accuracy and mechanical properties compared to final production components.

This document summarizes a project to develop a structure-property linkage model for glass fibre reinforced polymer (GFRP) composites. The project involves collecting micro-CT scan data from GFRP samples, segmenting the scans into fibre and matrix phases, simulating microstructures and properties using finite element analysis, extracting 2-point statistics from the microstructures, using principal component analysis for dimensionality reduction, and developing a regression model to link microstructure properties to predict physical properties. The initial model is validated against a limited number of samples and further work is suggested to improve the model with more real samples and experimental testing.

Improving the Strength of Acrylonitrile Butadiene Styrene Filament Used in th...
This document reviews improving the strength of acrylonitrile butadiene styrene (ABS) filament used in 3D printers. ABS is widely used for 3D printing due to its low cost and availability. However, ABS filament lacks strength. The document surveys research on techniques to increase the strength of ABS filament, such as reinforcing it with carbon fibers. Fused deposition modeling is the predominant 3D printing method that builds objects by extruding thin layers of heated ABS filament. The mechanical properties and tensile strength of ABS depend on factors like the orientation of printed strands. Improving the strength of ABS filament could enable more durable 3D printed parts.

The document describes a study that uses finite element analysis and Taguchi's method to optimize the preform shape of a connecting rod forging. The goal is to minimize forging load and produce defect-free forgings. Finite element software was used to simulate hot forging of the connecting rod under different preform design parameters, including flash thickness, width, and radii. Taguchi's method was then applied to design parameter combinations to determine the most influential parameters. Through several optimization iterations, the optimal preform shape that gave minimum forging load and complete die filling was obtained. The approach aims to reduce design time and costs compared to traditional trial and error methods.

COST EFFECTIVENESS OF HIGH PERFORMANCE CONCRETE
This document compares the cost effectiveness of using high performance concrete versus normal concrete for building construction. It discusses how high performance concrete can provide structural benefits like reduced member sizes, self-weight, and foundation costs. The document outlines a study that analyzed a multi-story building modelled in ETABS to compare concrete usage, steel reinforcement needs, and costs when using concrete grades from M20 to M40. It was found that using high performance concrete for columns and other load-bearing elements proved to be the most cost-effective option by reducing both the total volume of concrete and total construction costs.
Multiscale Modeling Approach for Prediction the Elastic Modulus of Percolated...
In this study the effective elastic modulus of cellulose nanocrystal CNC network is evaluated using multiscale method and micromechanical analysis. For this purpose, the elastic modulus of CNC water phases are randomly assigned to a two dimensional 2D checkerboard structure and the elastic response is evaluated. In addition, the effect of having a different number of phases CNC, water and interface is evaluated by assigning a discreet and continuous distribution of elastic modulus to checkerboard structure. When the number of phases increases dramatically, the distribution of phases is continuous and is defined with Weibull distribution. The results show that for two phase materials CNC and water when the microstructure has organized pattern the rule of the mixture and numerical model provide the same effective modulus, however when the microstructure is completely random, the self consistent micromechanical model should be used. Also, this study suggests 50 volume fraction as the percolation threshold for the CNC network with 10 GPa effective elastic modulus. The results from percolated multiphase network reveal that for microstructures with 4 phases and above, the percolated network converge to 35 GPa.

Energy and latency aware application
Energy efficiency is one of the most critical issue in design of System on Chip. In Network On
Chip (NoC) based system, energy consumption is influenced dramatically by mapping of
Intellectual Property (IP) which affect the performance of the system. In this paper we test the
antecedently extant proposed algorithms and introduced a new energy proficient algorithm
stand for 3D NoC architecture. In addition a hybrid method has also been implemented using
bioinspired optimization (particle swarm optimization) technique. The proposed algorithm has
been implemented and evaluated on randomly generated benchmark and real life application
such as MMS, Telecom and VOPD. The algorithm has also been tested with the E3S benchmark
and has been compared with the existing algorithm (spiral and crinkle) and has shown better
reduction in the communication energy consumption and shows improvement in the
performance of the system. Comparing our work with spiral and crinkle, experimental result
shows that the average reduction in communication energy consumption is 19% with spiral and

Abstract Digital image processing is the technique to process pixel variations on digital images. This paper employs the digital image processing procedure for microstructure analysis and enhancement of nodular cast iron properties inorder to determine the quality factors. This processing made to sharpen and enhance the microstructure before quantitative analysis. This analysis taken in the analog form of nodular cast iron was performed manually such that, it is time consuming for multiple set of images. To avoid this criteria probably, Digital Image Processing techniques are being used. Often the nodular cast iron images are corrupted or defected during transmission by impulse noise which is often filtered using median filters. In this paper, some of processing steps as pre-processing, segmentation, filtering process and edge detection are done on these images for effective and lossless transmission ensuring the counting of nodules in microstructure and detailed study of grain properties that correlates with the mechanical properties such as ductility, malleability and brittleness. Only 30% restoration of image applicable to an acceptable level is limited. A new filtering method – Resolution Based Median Filter (RBMF) is proposed which achieves more than 95% restoration of nodular cast iron images to an acceptable level. This method optimizes further microstructure analysis of grain smoothening and grain boundary detection using finite element simulation model by varying the intensity level of images. Keywords – Digital Image Processing, Material Microstructure, Edge Detection, Grain Boundary, Resolution Based Median Filter (RBMF).

Improving the Strength of Acrylonitrile Butadiene Styrene Filament Used in th...
This document reviews improving the strength of acrylonitrile butadiene styrene (ABS) filament used in 3D printers. ABS is widely used for 3D printing due to its low cost and availability. However, ABS filament lacks strength. The document surveys research on techniques to increase the strength of ABS filament, such as reinforcing it with carbon fibers. Fused deposition modeling is the predominant 3D printing method that builds objects by extruding thin layers of heated ABS filament. The mechanical properties and tensile strength of ABS depend on factors like the orientation of printed strands. Improving the strength of ABS filament could enable more durable 3D printed parts.

The document describes a study that uses finite element analysis and Taguchi's method to optimize the preform shape of a connecting rod forging. The goal is to minimize forging load and produce defect-free forgings. Finite element software was used to simulate hot forging of the connecting rod under different preform design parameters, including flash thickness, width, and radii. Taguchi's method was then applied to design parameter combinations to determine the most influential parameters. Through several optimization iterations, the optimal preform shape that gave minimum forging load and complete die filling was obtained. The approach aims to reduce design time and costs compared to traditional trial and error methods.

Multiscale Modeling Approach for Prediction the Elastic Modulus of Percolated...
In this study the effective elastic modulus of cellulose nanocrystal CNC network is evaluated using multiscale method and micromechanical analysis. For this purpose, the elastic modulus of CNC water phases are randomly assigned to a two dimensional 2D checkerboard structure and the elastic response is evaluated. In addition, the effect of having a different number of phases CNC, water and interface is evaluated by assigning a discreet and continuous distribution of elastic modulus to checkerboard structure. When the number of phases increases dramatically, the distribution of phases is continuous and is defined with Weibull distribution. The results show that for two phase materials CNC and water when the microstructure has organized pattern the rule of the mixture and numerical model provide the same effective modulus, however when the microstructure is completely random, the self consistent micromechanical model should be used. Also, this study suggests 50 volume fraction as the percolation threshold for the CNC network with 10 GPa effective elastic modulus. The results from percolated multiphase network reveal that for microstructures with 4 phases and above, the percolated network converge to 35 GPa.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
