We plan to construct an unmanned COVID-19 testing solution. Our main customers are organizations such as governments, schools, companies who want to provide affordable, easy and reliable testing services to associated people such as local citizens, students and employees. Upon agreement, we install our machines on customers’ sites. Our machine is capable of three testing methods: PCR Swab, PCR Saliva and Antigen Swab. Sample collection is completely automatic, and no people are required on site. Antigen samples can be analyzed directly inside the machine with results available in a short period of time. PCR samples will be collected by our employees and transported to our labs for further experiments. Test results will be reported to the customer organization, and we consider our process done. We also provide software interfaces, so that we can exchange data with the customer organization, such as user authentication info and test results.

The goal of this project is to design a 4-bit “Absolute-value Detector” with the minimum energy and worst-case delay of 800ps. Here “delay” refers to the worst-case propagation delay and “energy” refers to total energy drawn from VDD for a given input probability distribution. You may use gate sizing and supply voltage scaling as variables.

The Stratification Illusion
Stratification is a malicious tool used by the ruling class to diverge us from those well-established institutional problems and hinder us from bringing social changes. This essay will utilize various sociology theories to discuss how common people are forced to form the reality of a stratified society, why it is dangerous and whether there exist possible solutions.
The project implements the classic tic-tac-toe game on the Spartan-6 FPGA. The game board size is 3×3, and two human players are involved. The board of the game will be displayed on a monitor via VGA. The player who has the turn can press 4 buttons, UP, DOWN, LEFT, or RIGHT to move a blinking cursor on the board. When the cursor is moved to the target grid, the player can press the ENTER button to record the move, and if the game is not ended yet, the other player gets the turn. During the game, the 7-segment display will show the current location of the cursor, and which player’s move is now pending. We also need to constantly check whether or not the game should be over. There can be three outcomes: tie, Player 0 wins, or Player 1 wins. When a game-over condition is met, the game ends automatically, and no new moves are recorded. The final outcome will be shown on the 7-segment display. The user can press the RESET button to start a new game with an empty board.
This paper will compare the economic factors behind choosing between an Intel x86 MacBook Pro and an Apple M1 Pro (ARM) MacBook Pro through the perspective of a full-time video editor, a user-base known for demanding performance from their PCs.

It is intended for the general public who is interested in the incident but has no knowledge of shipbuilding, so only the management aspects of the failure will be included.
