The steamer ‘Ostrich’ ferries people between Dhaka and Barisal. Ostrich usually starts from
Dhaka around 7.30pm (evening/night depending on the season). At night, the visibility is
usually very low. So, the steamers/launches usually have a flashing signal light on the roof.
On top of that, the master of the steamer also honks the horn when necessary. This signal
light and the horn are both controlled by an Arduino Uno. The signal light flashes every 4s
whereas the horn is sounded whenever the master presses the horn switch. The horn switch
already has a small RC circuit attached to it to counter bouncing. Now, prepare a program in
Arduino Uno to control the signal light and the horn considering the information mentioned
above.

Write an assembly code that performs the following four tasks: enable the interrupt number 31, and sets its priority bits to 2, and clears its pending bit disable the interrupt 31 (Hints: Each interrupt has one enable bit, one pending bit, and one byte of priority.)

7. The number of surface flaws in plastic panels used in the interior of automobiles has a Poisson distribution with mean of 0.04 flaws per square foot of plastic panel. Assume automobile interior contains 10 square feet of plastic panel.(a) What is the probability that there are no surface flaws in an auto's interior?(b) If 10 cars are sold to a rental company, what is the probability that none of the 10 cars has any surface flaws?(c) If 10 cars are sold to a rental company, what is the probability that at most two cars have any surface flaws?

Please DO NOT respond to this question by copy/pasting the code provided elsewhere on the site, none of those work. Thanks. Virtual Memory Lab This lab project addresses the implementation of page-replacement algorithms in a demand-paging system. Each process in a demand-paging system has a page table that contains a list of entries. For each logical page of the process, there is an entry in the table that indicates if the page is in memory. If the page is in memory, the memory frame number that page is resident in is indicated. Also, for each page, the time at which the page has arrived in memory, the time at which it has been last referenced, and the number of times the page has been referenced since the page arrived in memory are maintained. The page table data structure is a simple array of page-table entries (PTEs). Each PTE contains five fields as defined below: struct PTE { int is_valid; int frame_number; int arrival_timestamp; int last_access_timestamp; int reference_count; } Each process in the system has a page table that is simply an array of PTEs. Each process also has a pool of frames that is allocated. The frame pool for a process is represented as an array of integers, where each Integer represents the frame number of a frame that is free and is available for use by the process. Note that in order to get the frame number in the pool, you first need to access the integer in the array. This lab project aims to exercise the various policies for page replacement. In particular, we study the following three page-replacement policies: First-In-First-Out (FIFO) Least-Recently-Used (LRU) Least-Frequently-Used (LFU) In order to implement the above policies, we need to develop corresponding functions that process page accesses for a process. That is, for each process, given its page table, a logical page number being referenced and the free frame pool of the process, the functions should determine the memory frame number for the logical page. Also, the functions should modify the page table and the free frame pool appropriately. The details of the functions with respect to the different policies are described below. You need to develop code for these functions that implement the specifications. Place the code in a file called virtual.c. You should include the oslabs.h file.

(At least two years of comparable financial statements are required.) a) Assess 7-Eleven’s financial position for year 2020 and 2021 according to i) liquidity position, and how the liquidity position has changed over time from 2020 to 2021. (6 marks) ii) asset management position, and how its asset management efficiency has changed over time. (6 marks) iii) debt management position, and how its debt management has changed over time. (6 marks) iv) profitability ratios, and how its profitability position has changed over time. (6 marks) v) market value ratios, and how its valuation has changed over time. (6 marks) b) Calculate 7-Eleven’s ROE as well as the industry average ROE, using the DuPont equation. From this analysis, how does 7-Eleven’s financial position. (10 marks) c) Write your opinion on what you think would happen to its ratios if the company initiated cost-cutting measures that allowed it to hold lower levels of inventory and substantially decreased the cost of goods sold. No calculations are necessary. Think about which ratios would be affected by changes in these two accounts. (10 marks)
