Visualizing Complexity: Navigating Algorithms with Algorithm Visualizer
Abstract: We think that studying algorithms may be amusing and exciting. Many students are currently struggling, but we hope to change that. Our strategy is to emulate gaming while learning. We're building hands-on learning exercises, such as mazes and patterns, to convey key concept. To help students understand how algorithms function in practice, we also use some stunning visualizations. Three major categories of algorithms are under our purview: sorting, pathfinding, CPU …

Design and Implementation of Low Power and Area Efficient Sub Threshold Level Shifter Using 16 nm CMOS Technology
Abstract: An efficient method of modifying subthreshold voltages is proposed here. As an alternative to static power dissipation, the suggested design allows for charging of internal nodes through VDDH. The force of the pull-down mechanism may be increased by connecting a second auxiliary circuit. The transition energy for input frequencies between 1 and 5 MHz is 84 fJ, the propagation delay is 46 ns, the dynamic power dissipation is 0.3 mW, …

Thermal Steganography: A New Way to Steal Data from Air-Gapped Computers Using Heat and Fan Noise
Abstract: Nowadays, high-security computers are "air-gapped," meaning they are not connected to the internet to prevent hacking. Cybercriminals are increasingly using direct, physical methods to access and take data instead of relying on internet-based attacks. This paper introduces a new cybersecurity threat called Thermal-Secret. Most existing heat-based attacks are very slow and fail if the room temperature changes. To solve this, we developed a Slope-Based method. Instead of looking at how …

Designing Digital Filters of Underwater Wireless Sensor Node
Abstract: Underwater Wireless Sensor Networks (UWSNs), an emerging area, integrate sensing, computing, and communication into a single compact device. The digital data is acquired using an FPGA (Field Programmable Gate Array), and the fusion of numerous sensor data is accomplished in the sensor node’s ARM (Advanced RISC Machine) CPU. The sensor interfacing circuit should connect the sensor to the sensor node’s data collecting system. The data from these sensors may be …

Design and Implementation of High-Speed Low Power Low Area Hybrid One Bit Full Adder Using CMOS Technology
Abstract: In this article, we'll take a look at a new kind of Full Adder (FA) design that mixes traditional Complementary Metal Oxide Semiconductors (CCMOS) with Pass Transistors (PTs) and Transmission Gates (TGs). To analyze the circuit's performance, we used the Mentor Graphics software package. Since all twenty (20) varieties of Full Adder circuits were able to be measured and compared, this research was conducted. When the clock rate of the …

64 Bit ALU DESIGN USING VEDIC MATHEMATHICS
Abstract: High-speed arithmetic operations are crucial for better performance in contemporary digital systems. Particularly for high bit-width operations, conventional arithmetic logic units (ALUs) frequently experience increased latency and complexity. This work presents the design and implementation of a 64-bit Arithmetic Logic Unit (ALU) using notions from Vedic mathematics. The suggested design makes use of a Kogge-Stone Adder for effective addition and the Urdhva Tiryagbhyam sutra for quick multiplication. Among other mathematical …
