Abrupt time variations of the properties of optical materials have been at the center of intense research efforts in recent years, with the prospect of enabling extreme wave transformations and of leveraging time as a degree of freedom for wave control. While the most viable approach to yield ultrafast variations of the optical material response is through optical pumping of nonlinear media, the complex dynamics in these systems are not yet fully understood. Here, as a relevant case study, we rigorously investigate the pump-probe dynamics in a 310nm-thick transparent conductive oxide etalon, using a weak 40 femtosecond probe and a pump that displays peak power densities in the TW/cm2 range with a duration of a few femtoseconds. We examine the pump-probe interaction using a hydrodynamic-maxwell approach that accounts for diffraction, self-focusing and -defocusing, self- and cross-phase modulation, probe gain, and linear and nonlinear material dispersion expanded in the perturbative regime up to 9th order for both pump and probe. By allowing the intricacies of the pump-probe interaction to proceed in time, we can also define an effective spatio-temporal permittivity for a more direct evaluation of the material ultra-broadband optical behavior. The reported results challenge the conventional modeling of this kind of problem, which has so far overlooked pump dynamics, simplistically assigning a local time-dependent refractive index to the probe that may be designed to fit the experimental data, but has no physical connection to the complex pump-probe interaction. Our approach unveils new dynamics, pointing towards the possibility to achieve extreme pulse compression into the attosecond range and nonlinear diffraction over deeply subwavelength propagation distances, thus opening a possible new path towards novel and cost-effective tools for integrated photonics and attosecond science. © 2025, CC BY-NC-ND.

Utilizing the vast amounts of data acquired by sensor networks set up in various businesses is the foundation of smart supply chain services. When it comes to exchanging data, Sensing as a Service (S2aaS) is an intriguing pattern of IoT business models. Data security, performance, privacy, and single point of failure are just a few of the reasons why the present centralized Internet of Things (IoT) S2aaS models aren’t cut out for IoT large data sharing. We present a decentralized framework for IoT S2aaS for smart supply chains that is based on blockchain technology. Without the need for intermediaries, this framework may ensure that data consumers can safely communicate data with data owners of IoT solutions while retaining full ownership of their data. Researchers lay out the framework’s layered architecture and system model, from which derive a specific plan for implementing IoT S2aaS through the usage of smart contracts. We put an Ethereum-based software prototype into action. The outcomes of the experiments prove that our solution is both valid and effective.

In today's world VANET get a lot of attention because of its easy and comfortable less infra-structure and life-saving factor. But whatever the facilities is available now it's not properly able to provide a strong security to the vehicle to vehicle (V2V) or vehicle to infrastructure communication (V2I) so attacks obey the authentication, confidentiality, and security which can influence the privacy of the user. The mechanism of VANET is unloosed with a lot of security risk nowadays. This paper gives an idea of VANETS architecture, existing work in VANET with security issues and challenges. Further, provide the solution to that issue with comparative analysis and use group-based key share algorithm which is enhanced the privacy of users and provides some research guidance for upcoming work.

The ability to drive a car is a significant step toward independence for individuals with impairments, however, the standard driving system placed in a car does not provide the functionality for the challenged driver to operate the vehicle. Hence, in this project, we focused on designing a prototype of a car that works with the help of renewable energy like solar for people who have disabilities related to their legs or arms. It will be very helpful for those people who have physical disabilities to drive from one place to another without counting on anybody. The research shows that the issues about sustainable mobility are gaining increasing attention both in public opinion and specialists because of the major impact of automotive systems on carbon Dioxide production, climate change (global warming), and fuel exhaustion. So, by using renewable energy such as solar energy as source power it helps pollution-free, sustainable, and causes no greenhouse gases which will save the environment in the future. Probably the best development in the clinical field that helped both the old and the impeded is the portability vehicle. The expense of the vehicle may not be reasonable for an average person. In this case, an endeavor is made to manufacture a Solar Electric vehicle for disabled people at an ideal cost that can be used easily. It ensures the physically challenged people to be comfortable in travel and life. As solar energy is the main source on which we are focusing nowadays, because of many reasons like pollution, cost of fuel and also due to unavailability of the fuels. In the future solar energy will be the major source. The features have made in this solar electric vehicle are intelligent ones and are very useful for physically disabled people who want to be independent. In addition to that, the GSm is attached to the vehicle for monitoring disabled people. If the vehicle got any damage or the people is in out of control or any other irregular activities are found

This article synthesizes the insights gained through presentations and discussions at the 2023 IEEE Workshop on Norbert Wiener in the 21st Century (21CW2023), which focused on "The Future of Work in the Age of Automation."Hosted at Purdue University, this interdisciplinary convening of technologists, social scientists, and humanists explored the impacts of automation on labor, drawing on Wiener's legacy of insights as a backdrop to examine the technologically mediated future we face in coming decades. The workshop presented a rare opportunity to reflect critically on these issues at a pivotal moment in human and technological history, and to elicit underappreciated dimensions. Areas of focus include: the qualitative and quantitative losses associated with automation and AI, the impacts automation has for questions about the meaningfulness of work, the challenges we face related to uncertainty and lack of predictability in technological advancement, and the opportunities that exist for centering human values and agency in these conversations. While acknowledging many items for concern in the context of automation in the future of work, such as the domination of economic narratives, a potential loss of qualitative texture, and the neglect of certain issues key to human identity, the authors conclude by offering optimistic visions - or calls - for redefining value and labor, preserving human agency, and embracing creative problem-solving. © 2024 IEEE.

Recently, new technologies are introduced to minimize the disorderly disposal of waste, not only from the processing of ornamental stones (OS), but also from other industrial sectors. A technological alternative to reduce the environmental impact and recycle waste is its incarnation into clayey ceramic products. This solution can improve the properties of the final product. Some studies using granite residues, from sawing blocks, showed great potential for their use in red ceramics, due to their characteristics such as a high content of alkaline oxides , fine granulometry , and low cost. The goal of this work is to characterize the residues from the processing of OS, with the aim to incarnate into clayey ceramics. The characterization will contribute to the knowledge of the residue (mud) and, through this fact, will favor the study of a possible solution to the problem of disposal of mud generated in the sawing of rocks, besides contributing to the practice of sustainable development , and the consequent use of waste discarded as unusable.

Introduction of Synchronized phasor measurement unit (PmU) in power system is a solution for monitoring system wide disturbances. PmUs provide precise information about a system's phasors such as magnitude and phase angle of sine waves of the system. PmU data is a valuable source when determining the post-mortem of a fault, or a system disturbance. It can be unveiled what time the system began to falter and exactly what instabilities the system experienced. Knowing the cause of such instabilities will allow enhancement of the current system protection system. This will help in minimizing risk, disruptions or total system collapse. PmUs are synchronized via global positioning system (GPS). For wide area monitoring (WAm), synchronization of the PmUs allows for interconnected systems to be monitored simultaneously, giving real time records. This paper explores the impact of PmU in modern power system, deployment strategies of PmU network around Texas tech University, importance of PmU data collected from the network, correlation of events by data analysis and focus on how the time stamped information is valuable for grid stability. The ongoing smart architecture of grid will increase dependency and importance on PmU based network in future.
