Heat and mass transfer in porous media is a complex mathematical problem involving multiple partial differential equations. The current paper brings into picture the solution strategy to be applied using finite element method to solve the heat and mass transfer along with viscous dissipation in Cartesian coordinates. The applied methodology is successful in predicting the heat and mass transfer.

One of the greatest issues facing the nation today is the energy crisis. The energy crisis can be mitigated to some extent if people keep track of our energy consumption and avoid wasting it. People nowadays confront a variety of issues, including electricity theft. One’s own country’s economy has a major significant influence on electric power theft and is a type of crime. In this research, an IoT-based power utilizedis proposed andit is measured utilizing current and voltage sensor reading. The proposed IoT technology will readily detect energy theft. This Internet of Things is connected with an Arduino UNO IDE with a Wi-Fi module for IoT connectivity andcustomers will receive information viathe Blynk app. A current sensor is also included in this smart electricity meter, which relays the current information to the microcontroller. Users must connect cell phones to Blynk app so that the electricity theft can be tracked and monitored,which can help you to set up your system. The reading appears on the IoT screen as soon as it activates the system. The reading will be altered following the passage of time. If energy theft occurs, the theft will be detected and displayed on the IoT screen. To prevent theft, the user can use the IoT Blynk app to monitor the tracking of power utilized by the system anywhere and at any time, even after receiving the theft indication signal.

Idealized simulations of the tropical atmosphere have predicted that clouds can spontaneously clump together in space, despite perfectly homogeneous settings. This phenomenon has been called self-aggregation, and it results in a state where a moist cloudy region with intense deep convectivestorms is surrounded by extremely dry subsiding air devoid of deep clouds. We review here the main findings from theoretical work and idealized models of this phenomenon, highlighting the physical processes believed to play a key role in convective self-aggregation. We also review the growing literature on the importance and implications of this phenomenon for the tropical atmosphere, notably, for the hydrological cycle and for precipitation extremes, in our current and in a warming climate.

Proceedings of Meetings on Acoustics 2021年第1期44卷

作者： Safaa N. Awny Bilal A. Jebur Charalampos C. Tsimenidis 1University of Mosul Mosul Nineveh 41002 IRAQ safaanawny@*** 2Department of Computer and Information Engineering Ninevah University Mosul Nineveh 41002 IRAQ bilal.jebur@uoninevah.edu.iq 3School of Engineering Newcastle University Faculty of Science Agriculture and Engineering Newcastle Upon Tyne NE1 7RU UNITED KINGDOM charalampos.tsimenidis@newcastle.ac.uk

Cooperative communication systems can solve the data rate limitations in underwater acoustic channels (UAC) introduced by their half-duplex (HD) nature and bandwidth limitations. In this paper, Hierarchical Modulation (HM) is introduced to both enhance the system throughput and spectral efficiency, as well as to enable various degrees of priority communication links. The proposed system utilizes HM with orthogonal frequency division multiplexing modulation (OFDM) in a two-way relay network (TWRN) using physical layer network coding (PLNC) to exchange information between two nodes operating in HD mode. The performance of the proposed PLNC-TWRN system is analysed via simulations using realistic UAC and numerical results are presented to demonstrate that it can significantly enhance the throughput.

Advancing agrivoltaics within the U.S. legal framework: A multidimensional assessment of barriers & opportunities

引用

AIP Conference Proceedings 2022年第1期2635卷

作者： Alexis S. Pascaris Chelsea Schelly Joshua M. Pearce 1Department of Social Sciences Michigan Technological University 1400 Townsend Drive Houghton MI 49931 USA 2Department of Electrical & Computer Engineering Western University 1151 Richmond St. N.

To support the broader realization of agrivoltaics in the U.S., this research provides a multidimensional assessment of the socio-political barriers and opportunities for development. A synthesis of five empirical studies is presented: 1) an investigation of the impediments to farmer adoption; 2) an exploration of development challenges from the perspective of solar industry professionals; 3) a survey gauging public support and siting preferences for agrivoltaics; 4) a life cycle assessment of a pasture-based agrivoltaic system; and 5) the development of a comprehensive legal framework for agrivoltaics in the U.S. The assessment reveals the intersectionality among key stakeholders, communities, the environment, and legal frameworks, which can inform agrivoltaic decision making, stakeholder relations, and policy design globally. The primary socio-political barriers identified include: techno-economic challenges, community resistance, lack of financial incentive for both sectors, and restrictive local land use policy. The central socio-political opportunities include: income diversification, enhanced community relations and acceptance, energy demand and emissions reduction, and policy integration between key sectors. These findings demonstrate the need for multidimensional and interdisciplinary approaches to agrivoltaic development and an increased research focus on socio-political considerations.

Head in 1987 was the first person to introduce the concept of splicing system as a theoretical model for DNA based computation using splicing operation. Splicing operation is a method of cutting and recombining DNA molecules under the influence of restriction enzymes such as ligase. Previous researches have proven that splicing systems with finite sets of axioms and rules generate only regular languages. Hence, in order to increase the computational power of the languages generated by splicing systems, several restrictions in the use of rules have been considered. In this paper, simple splicing systems controlled by permutation groups are defined and the computational power of the languages generated by this variable is explored.

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
