Waterless dyeing Presentation
Waterless dyeing Presentationalaminmasum1 The document discusses two types of waterless dyeing processes: air dyeing technology and DyeCoo dyeing which uses supercritical carbon dioxide. Air dyeing uses air instead of water to help dyes penetrate fibers by heating and injecting dye gas directly into fibers. It uses up to 95% less water and 86% less energy than traditional dyeing. DyeCoo dyeing involves dissolving dyes in supercritical carbon dioxide due to its low viscosity and surface tension properties, then transporting and adsorbing the dyes onto fibers through diffusion, without using water. It provides advantages like eliminating water treatment and pollution but requires high pressure and temperature during processing.

ADVXAI IN MALWARE ANALYSIS FRAMEWORK: BALANCING EXPLAINABILITY WITH SECURITY
ADVXAI IN MALWARE ANALYSIS FRAMEWORK: BALANCING EXPLAINABILITY WITH SECURITYijscai With the increased use of Artificial Intelligence (AI) in malware analysis there is also an increased need to
understand the decisions models make when identifying malicious artifacts. Explainable AI (XAI) becomes
the answer to interpreting the decision-making process that AI malware analysis models use to determine
malicious benign samples to gain trust that in a production environment, the system is able to catch
malware. With any cyber innovation brings a new set of challenges and literature soon came out about XAI
as a new attack vector. Adversarial XAI (AdvXAI) is a relatively new concept but with AI applications in
many sectors, it is crucial to quickly respond to the attack surface that it creates. This paper seeks to
conceptualize a theoretical framework focused on addressing AdvXAI in malware analysis in an effort to
balance explainability with security. Following this framework, designing a machine with an AI malware
detection and analysis model will ensure that it can effectively analyze malware, explain how it came to its
decision, and be built securely to avoid adversarial attacks and manipulations. The framework focuses on
choosing malware datasets to train the model, choosing the AI model, choosing an XAI technique,
implementing AdvXAI defensive measures, and continually evaluating the model. This framework will
significantly contribute to automated malware detection and XAI efforts allowing for secure systems that
are resilient to adversarial attacks.

Taking AI Welfare Seriously, In this report, we argue that there is a realist...MiguelMarques372250 In this report, we argue that there is a realistic possibility that some AI systems
will be conscious and/or robustly agentic in the near future. That means that the
prospect of AI welfare and moral patienthood — of AI systems with their own
interests and moral significance — is no longer an issue only for sci-fi or the
distant future. It is an issue for the near future, and AI companies and other actors
have a responsibility to start taking it seriously. We also recommend three early
steps that AI companies and other actors can take: They can (1) acknowledge that
AI welfare is an important and difficult issue (and ensure that language model
outputs do the same), (2) start assessing AI systems for evidence of consciousness
and robust agency, and (3) prepare policies and procedures for treating AI systems
with an appropriate level of moral concern. To be clear, our argument in this
report is not that AI systems definitely are — or will be — conscious, robustly
agentic, or otherwise morally significant. Instead, our argument is that there is
substantial uncertainty about these possibilities, and so we need to improve our
understanding of AI welfare and our ability to make wise decisions about this
issue. Otherwise there is a significant risk that we will mishandle decisions about
AI welfare, mistakenly harming AI systems that matter morally and/or mistakenly
caring for AI systems that do not.

Dust Suppressants: A Sustainable Approach to Dust Pollution Control
Dust Suppressants: A Sustainable Approach to Dust Pollution ControlJanapriya Roy This journal explores the growing field of bio-organic dust suppressants as a sustainable solution to dust pollution. It reviews the working principles of dust suppression, key performance indicators, and the latest research on using natural materials like polysaccharides, lignin, proteins, and agricultural wastes. It also highlights current challenges and future directions to enhance the durability, cost-effectiveness, and environmental safety of bio-based dust control technologies. A valuable reference for researchers, environmental engineers, and industry professionals seeking eco-friendly dust management solutions.
Dust pollution, whether natural or anthropogenic, poses significant threats to both the environment and public health. Effective dust suppression technologies are essential in mitigating airborne particulate matter, especially in industrial, mining, and construction settings. Recently, bio-organic materials have emerged as promising raw materials for eco-friendly dust suppressants. This paper explores the working principles of dust suppressants, key performance evaluation indices, and the current progress in developing bio-based dust control agents using polysaccharides, lignin, proteins, microorganisms, and agricultural or forestry waste. It also discusses existing challenges and future research directions for enhancing the efficiency and applicability of bio-organic dust suppressants.
Working Principles of Dust Suppressants
Dust suppressants operate primarily through three interrelated mechanisms: wetting, coagulation, and consolidation.
Wetting: This mechanism involves the application of dust suppressants to reduce the surface tension of water, allowing it to penetrate and coat dust particles. This increases the weight and cohesion of the particles, causing them to settle quickly. Surfactants and hygroscopic agents are commonly used in this approach.
Coagulation: Dust particles are brought together to form larger aggregates through electrostatic interactions or binding agents, which helps in accelerating their settling.
Consolidation: A more long-term effect where the suppressant forms a crust or mesh-like structure over the dust-prone surface, physically stabilizing it and preventing re-entrainment of particles by wind or vehicle movement.
Bio-Organic Materials in Dust Suppressants
The shift toward natural, renewable, and biodegradable components has led to extensive research on the use of various bio-organic substances, including:
Polysaccharides: Starch, cellulose derivatives, and chitosan can form gels or films that stabilize surfaces.
Lignin: A byproduct of the paper industry, lignin offers strong binding capacity and is naturally water-resistant.
Proteins: Derived from agricultural waste, proteins like casein and soy protein can enhance binding and wetting.
Microorganisms: Certain bacteria and fungi can produce biofilms or exopolysaccharides that trap dust particles.

Building Security Systems in Architecture.pdf
Building Security Systems in Architecture.pdfrabiaatif2 Building security systems are essential for protecting people, property, and assets within a structure. These systems include a range of technologies and strategies such as surveillance cameras (CCTV), access control systems, alarm systems, security lighting, and motion detectors. Modern security solutions often integrate smart technology, allowing remote monitoring and real-time alerts through mobile devices. Access control systems, like key cards or biometric scanners, ensure that only authorized individuals can enter certain areas, enhancing both safety and privacy. Alarm systems, whether triggered by unauthorized entry, fire, or environmental hazards, play a critical role in emergency response. Additionally, video surveillance acts as both a deterrent and a tool for investigating incidents. An effective building security system is carefully planned during the design phase, taking into account the building's size, purpose, and potential risks. Ultimately, robust security systems are vital for ensuring peace of mind, protecting lives, and preserving valuable assets.
