The Traffic-Aware Scatter Net Scheduling (TASS) algorithm is an advanced scheduling strategy designed to reduce the latency of the data transmission in wireless networks. It is a hybrid technique that combines both the advantages of a random-access scheduling scheme and a deterministic scheduling scheme. The TASS algorithm is based on two main components: the "scatter" and the "aware." The scatter part of the algorithm randomly assigns nodes to different time slots, while the aware part of the algorithm takes into account the current network traffic. By using the aware part of the algorithm, the TASS algorithm can schedule transmissions in such a way that it reduces the latency of data transmission. The main advantages of the TASS algorithm are its ability to reduce the latency of data transmission and its flexibility in adapting to changes in the network traffic. The algorithm is also designed to be resilient to any changes in the network topology, allowing it to quickly adapt to changing network conditions. Furthermore, the algorithm is designed to be energy efficient, as it minimizes the number of control messages that need to be sent and received.

The COVID-19 illness primarily carried by a Corona viral, commonly known as SARS-CoV-2. The rapid pace of such a drug's growth over six of the seven planets, except South, was already reported. Ever since it appeared, it has caused serious damage for many sectors and didn't harm the luxury goods sector. A major gate as in transition is opened by the epidemic. The COVID-19's effects on the Indian economy are negative. A old company concept needs to evolve to meet the demands of present.Through a clever absorption of internet media, method, & aptitude in any point & activity, the change as in setting of online is witnessed in all areas, i.e., in society, organisation, or in the exactness like an organisation, only in companies, or in the environment. Technology is used in conjunction with industry 4.0 (also known as DX or DT) to generate value for key parties (users in the totality), and to develop and gain the capacity for quickly adapting to situations which are altering.Any item or service may now be marketed but also advertised to customers online thanks to change carried out in a data - driven method, which has done away with the need for external middlemen. A large number of firms are impacted by COVID-19 since it has an impact to the entire globe and causes social estrangement with customers. In light of social distance, a wide range of sectors and businesses will be impacted. In this research, the idea of digitisation is proposed as a projected way through. Social distance may alter the characteristics or the purchasing habits. This study is being done to determine how it COVID-19 problem will affect consumer purchasing habits. By using internet tactics and strategies, consumers are shifting the way that merchandise and services are traditionally purchased. As per research, the digital advertising framework has permeated our imagination for acquiring the ways that are best for selling from several top-performing businesses.Only thing changing in regard of consumer purchase intention following COVID-19 recuperation would be the sales for items, which will mostly stay same with. Consumers will develop the buying habit so as protection, physically or straight from creators.

5G communications at frequencies below 6 GHz require a new type of antenna, thus designers have created a wideband microstrip patch antenna (WMP A). To achieve such a broad frequency range, the suggested antenna makes use of a new defective ground structure (DGS). For the antenna to work better, a triangular strip is added to the ground plane. In addition to improve the gain of the microstrip-antenna, the WMP A proposed uses the reflective plate to focus on the side lobes and reduce the creation of the main lobes. The suggested WMP A is designed and built on a FR-4 epoxy substrate, and the inset feed approach is utilised in order to provide the WMP A with its input. Utilizing the CST Microwave Studio Suite, the simulation of the proposed antenna and its subsequent optimization are carried out. The WMP A takes up a minimal amount of space on the substrate, yet it achieves excellent results in terms of gain, directivity, and radiation efficiency. The suggested antenna has a frequency range of 4.93 GHz to 5.765 GHz, which allows it to cover the sub-6 GHz portion of the 5G spectrum ranging from 4.9 GHz to 5.8 GHz. The computed and measured properties of the antenna demonstrate that the this high gain compact WMPA is suitable for the applications operating at frequencies below 6 GHz.

In this study, the schematics for Magnetic Tunnel Junction-Magnetoresistive Random Access Memory (MTJ-MRAM) are designed and simulations are carried out in 45 and 90 nm Complementary Metal-Oxide Semiconductor (CMOS) Very Large Scale Integration (VLSI) technology using analog design environment. Other memory circuits like volatile Static Random Access Memory (SRAM) and non-volatile flash memory are designed and behavioural waveforms verified. The output behavioural characteristics of MTJMRAM are compared with that of SRAM and flash memory. The attributes like power and delay are calculated and compared with SRAM and flash memory circuits. The study was carried out in order to integrate the non-volatile memory with field-programmable gate array (FPGA) architecture and design a nonvolatile memory-based FPGA. MTJ-MRAM shows better performance than volatile SRAM and nonvolatile flash memory in terms of power and delay parameters.
