Integrating social and environmental impacts of green transportation infrastructure : a framework for effective decision-making
Green Infrastructure (GI) gains recognition as a viable alternative to traditional infrastructure due to its economic, environmental, and social benefits. However, quantifying and monetizing GI\u27s social and environmental impacts pose challenges, leading to their neglect in comparative evaluations. To heighten GI\u27s appeal, this study introduces a novel framework that incorporates social and environmental impacts and public opinion using the Analytical Hierarchy Process and Monte Carlo simulation. The framework offers a comprehensive approach to evaluate GI\u27s impact. Findings from a Philadelphia project demonstrate that projects with more GI elements are cost-effective when considering public opinion and long-term benefits. The research emphasizes the importance of incorporating GI\u27s threefold benefits into evaluation frameworks, aiding decision-makers in making informed choices by accounting for social, environmental, and economic impact
Enabling Green Energy awareness in Interactive Cloud Application
International audienceWith the proliferation of Cloud computing, data centers have to urgently face energy consumption issues. Although recent efforts such as the integration of renewable energy to data centers or energy efficient techniques in (virtual) machines contribute to the reduction of carbon footprint, creating green energy awareness around Interactive Cloud Applications by smartly using the presence of green energy has not been yet addressed. By awareness, we mean the inherited capability of Software-as-a-Service applications to dynamically adapt with the availability of green energy and to reduce energy consumption while green energy is scarce or absent. In this paper, we present two application controllers based on different metrics (e.g., availability of green energy, response time, user experience level). Based on extensive experiments with a real application benchmark and workloads in Grid'5000, results suggest that providers revenue can be increased as high as 64%, while 13% brown energy can be reduced without deprovisioning any physical or virtual resources at IaaS layer and 17 fold increment of performance can be guaranteed
An Efficient Transfer Learning-based Approach for Apple Leaf Disease Classification
Correct identification and categorization of plant diseases are crucial for
ensuring the safety of the global food supply and the overall financial success
of stakeholders. In this regard, a wide range of solutions has been made
available by introducing deep learning-based classification systems for
different staple crops. Despite being one of the most important commercial
crops in many parts of the globe, research proposing a smart solution for
automatically classifying apple leaf diseases remains relatively unexplored.
This study presents a technique for identifying apple leaf diseases based on
transfer learning. The system extracts features using a pretrained
EfficientNetV2S architecture and passes to a classifier block for effective
prediction. The class imbalance issues are tackled by utilizing runtime data
augmentation. The effect of various hyperparameters, such as input resolution,
learning rate, number of epochs, etc., has been investigated carefully. The
competence of the proposed pipeline has been evaluated on the apple leaf
disease subset from the publicly available `PlantVillage' dataset, where it
achieved an accuracy of 99.21%, outperforming the existing works.Comment: Accepted in ECCE 2023, 6 pages, 6 figures, 4 table
12-segment display for the Bengali numerical characters
For representing the Bengali numerical characters the researchers have been working for a long time. In this paper, the idea of 12-segment display is introduced which ensures better outlook than the existing or proposed display systems. A 12-segment display for Bengali Numerical Characters needs 4-bit inputs for representing each digit. Appropriate logic circuits are also designed for that purpose
Maximally mixing active nematics
Active nematics are an important new paradigm in soft condensed matter
systems. They consist of rod-like components with an internal driving force
pushing them out of equilibrium. The resulting fluid motion exhibits chaotic
advection, in which a small patch of fluid is stretched exponentially in
length. Using simulation, this Letter shows that this system can exhibit stable
periodic motion when sufficiently confined to a square with periodic boundary
conditions. Moreover, employing tools from braid theory, we show that this
motion is maximally mixing, in that it optimizes the (dimensionless)
``topological entropy'' -- the exponential stretching rate of a material line
advected by the fluid. That is, this periodic motion of the defects,
counterintuitively, produces more chaotic mixing than chaotic motion of the
defects. We also explore the stability of the periodic state. Importantly, we
show how to stabilize this orbit into a larger periodic tiling, a critical
necessity for it to be seen in future experiments
Structural Analysis and material selection for biocompatible cantilever beam in soft robotic nanomanipulator
This paper investigates the selection of appropriate materials for cantilever beams in surgical robotic nanomanipulators. Cantilever beams play a crucial role in soft robotic surgery. Biocompatible materials, which have minimal adverse effects on biological systems, are commonly used for these beams. Using SOLIDWORKS software simulation, the study assesses the flexibility of cantilever beams made from different biocompatible materials. The analysis involves varying the applied force (0.001 µN to 0.004 µN), beam length (80 µm, 120 µm, and 160 µm), and beam thickness (0.4 µm, 0.6 µm, and 0.8 µm). Four materials—Alumina, Poly-Ether-Ether-Ketone (PEEK), Polyurethane (PUR), and Ti-6Al-4V—are evaluated. Simulation results highlight Polyurethane (PUR) as a suitable material for cantilever beams in nanomanipulators due to its favorable properties. These findings provide valuable insights for the design and advancement of efficient and reliable robotic nanomanipulators, advancing the field of soft robotic surgery
A Survey: Implementations of Non-fungible Token System in Different Fields
In the realm of digital art and collectibles, NFTs are sweeping the board.
Because of the massive sales to a new crypto audience, the livelihoods of
digital artists are being transformed. It is no surprise that celebs are
jumping on the bandwagon. It is a fact that NFTs can be used in multiple ways,
including digital artwork such as animation, character design, digital
painting, collection of selfies or vlogs, and many more digital entities. As a
result, they may be used to signify the possession of any specific object,
whether it be digital or physical. NFTs are digital tokens that may be used to
indicate ownership of one of a-kind goods. For example, I can buy a shoe or T
shirt from any store, and then if the store provides me the same 3D model of
that T-Shirt or shoe of the exact same design and color, it would be more
connected with my feelings. They enable us to tokenize items such as artwork,
valuables, and even real estate. NFTs can only be owned by one person at a
time, and they are protected by the Ethereum blockchain no one can alter the
ownership record or create a new NFT. The word non-fungible can be used to
describe items like your furniture, a song file, or your computer. It is
impossible to substitute these goods with anything else because they each have
their own distinct characteristics. The goal was to find all the existing
implementations of Non-fungible Tokens in different fields of recent
technology, so that an overall overview of future implementations of NFT can be
found and how it can be used to enrich user experiences.Comment: 14 pages, 3 figures, 3 table
Risk communication during COVID-19 pandemic: impacting women in Bangladesh
Risk communication during COVID-19 is essential to have support, but it is challenging in developing countries due to a lack of communication setup. It is more difficult for the low-income, marginal communities, and specifically, women in developing countries. To understand this, particularly during the COVID-19 pandemic, we conducted a qualitative study among N = 37 women (urban 20, rural = 17) across Bangladesh that presents the risk communication factors related to social and financial challenges. It reveals that the majority of the urban communities lack communication with local authorities, where urban low-income communities are the worst sufferers. Due to that, the majority of the urban participants could not get financial support, whereas the rural participants received such support for having communications with local authorities during the pandemic. However, access to technology helped some participants share and receive pandemic-related information about risk communication, and the adoption of financial technology helped to get emergency financial support through risk communication. Moreover, this work is expected to understand the role of risk communication during the COVID-19 pandemic among women in Bangladesh
