Moreover, it shows how FinFETs can be effectively integrated with high density by using the three-dimensional configuration to improve short-channel effects control. Double-gate transistors can be used instead of MOSFETs with electrostatic control superiority. On the other hand, Trigate Transistors are known for their speed and power efficiency. GAAFETs have gate-all-around architecture, which helps in electrostatic control and minimizes leakage current. Lastly, TFETs operate under reverse bias and have tunneling to conduct current; they are efficient in terms of energy and speed. This review highlights the excellent journey of the development of transistors from the first one in 1947.

If there are enough redundant nodes available to keep the network functioning and connected in the event of node failures, the network's ability to self-organize makes it robust and fault-tolerant. The router, which plays a key role in organizing the data flow, is the brain of an on-chip network. The main components of the WSNs are the routers, which oversee sending messages and publishing-subscribe events between senders and receivers. A high level of parallelism and a fast on-chip router are both made possible by allowing routing functions for each input port and utilizing distributed arbiters. The research article focuses on the hardware chip design of mesh configured network on chip routers chip with embedding RSA cryptographic algorithm. The chip design is done in Xilinx ISE, simulated in Modelsim with different key sizes, and analyzed on Virtex-5 field programmable gate array.

This research focuses on enhancing SoMIT over hospital communication networks using a soft computing-driven framework (Hybrid Fuzzy-AHP) method within the Multiple-Criteria Group Decision Making (MCGDM) technique. The Hybrid Fuzzy-AHP method considers five critical medical image security (MIS) parameters: integrity [MS1], authentication [MS2], confidentiality [MS3], access control [MS4], and availability [MS5]. Furthermore, this soft computing technique assigns weighted prioritization to each MIS parameter, indicating that integrity holds the highest impact, followed by authentication, confidentiality, access control, and availability. The MIS optimization outcome of 0.8075 signifies robust security according to the triangular fuzzy number (TFN) scale. These MIS security outcomes were validated using GNU Octave and MATLAB tools. Additionally, a comparison between the proposed Hybrid Fuzzy-AHP method and various MCGDM techniques shows that the proposed method outperforms other MCGDM techniques. This research significantly contributes to the development of secure and efficient medical image transmission (MIT) systems.

The BPS method necessitates the use of a bit-slicing algorithm to include hidden data in any one of the eight slices. This method uses 8 bits to represent each pixel in an (8 × 8) image. The information in a grayscale image is encoded using 8 bits since each pixel's value falls between 0 and 255. Bit plane slicing is widely used in data hiding, image compression, and other related applications of image processing in security, privacy, encryption-decryption, health care data processing, and so on. The research article provides bit plane slicing concept realization in hardware chips for digital image processing in which the 4-bit and the 8-bit images are processed to estimate the different planes and corresponding values in Xilinx ISE14.7 software using VHDL programming.

Based on the results, suitable regions for plant factory/vertical farms locations were suggested. The study analyses the heat losses due to wind in two scenarios with various wall surfaces based on annual wind speed, direction, and temperature experimental data from a mast. The heat transfer in a wall surface with 10 m<sup>2</sup> and an annual average wind speed of 4.6 m/s, can be more than 18 MWh/yr. The investigation showed that while places outside the built-up agglomerations can face noticeably larger heat losses, there are sites within Davleia with low wind speeds that can limit heat loss.
