Crowdfunding serves as a method for individuals or organizations to gather funds for projects through small contributions from a large number of people, typically facilitated online, as exemplified by platforms like Kickstarter. The adoption of crowdfunding platforms has simplified the connection between business owners and a global audience willing to support their initiatives. However, the current crowdfunding system faces challenges such as high maintenance costs, limited system openness, and a lack of user confidence. Addressing these issues, a proposed project introduces a blockchain-based solution with an immutable ledger recording every transaction. Utilizing a peer-to-peer network, each system serves as both a client and a server. The project incorporates features like a voting mechanism for donors and an alert system for low gas prices, enhancing transparency through blockchain technology and fundamentally distinguishing itself from existing solutions. By leveraging smart contracts, the project aims to ensure the protection of funds and provide users with enhanced transparency and trust in the crowdfunding process.

Wood-based bio-composites are materials that combine wood or wood-derived components with bio-based polymers, fibers, or other natural materials to form a composite material. These composites are designed to utilize renewable and sustainable resources, such as wood, in their composition. The Department of Mechanical Engineering at the University of Mississippi, The Department of Sustainable Bioproducts at Mississippi State University, and Alcorn State University focused on creating new wood-based bio-composites from agricultural and plant-based materials in response to the current trends toward natural-based composites. It is imperative to study the structural properties of newly developed bio-composites to find the potential capabilities and applications. The materials tested were made from southern yellow pine (SYP), a commercial urea-formaldehyde (UF Unibond) resin, and a polymeric methylene diphenyl isocyanate (pMDI) resin using a Dieffenbacher hot press. The dynamic and damping properties were determined using the hammer excitation vibration technique. The responses were obtained from the frequency domain for the fundamental natural frequency (fn). The panel made using 4% pMDI resin (Material 1) demonstrated the highest average storage modulus (4.32 GPa), indicating superior stiffness and potential for use in load-bearing applications where structural integrity is essential. The panel made with 5.3% UF resin (Material 2) exhibited the highest average damping ratio (0.02), suggesting its effectiveness in reducing vibrations and providing damping in dynamic applications. Overall, these materials have distinctive attributes that cater to specific application requirements. Any of the three materials could be considered a viable option depending on the intended use.

In order to mitigate the proliferation of deceptive employment solicitations on the internet, a sophisticated automated tool employing machine learning-based classification methodologies is posited within the confines of this scholarly work. Various classifiers are deployed to scrutinize online postings for fraudulent employment opportunities, and the outcomes of these classifiers are systematically juxtaposed to ascertain the most efficacious model for detecting spurious job listings. This approach facilitates the identification and subsequent elimination of counterfeit job posts from an extensive array of online submissions. The investigation encompasses two principal categories of classifiers: individual classifiers and ensemble classifiers, both instrumental in discerning deceitful job postings. Nonetheless, empirical findings unequivocally affirm that ensemble classifiers exhibit superior efficacy in discerning scams when compared to their singular counterparts. The technological landscape has ascended to a heightened echelon, ushering in a paradigm wherein corporations engage in the recruitment of personnel through the conduit of online methodologies. This not only expedites the acquisition of requisite personnel for businesses but also augurs well in terms of cost-effectiveness. The virtual expanse facilitates individuals in procuring employment commensurate with their qualifications and desired occupational spheres. However, the veracity of these posted job opportunities remains shrouded, posing an inherent challenge for job seekers. In response to this predicament, we proffer a pioneering software meticulously crafted to prognosticate the authenticity of job posts, discerning between genuine and spurious listings. Embarking upon the realm of machine learning, our innovative system, aptly named "Fake Job Post Prediction," leverages the formidable Random Forest classifier. This sophisticated algorithm boasts a commendable efficiency in generating precise outcomes, with a remarkable 98% accuracy vis-à-vis its predecessors. Recognizing the perils faced by students or job seekers navigating the labyrinth of online employment opportunities, our system becomes a beacon of protection against unwittingly submitting personal information to fraudulent job posts. Instances of potential deception, such as solicitation of application fees or promises of employment contingent upon monetary transactions, are thus preemptively averted through the discerning capabilities of our framework, thereby safeguarding users from falling prey to scams.
