disadvantages of using lossless compression rather than lossy compression
Answer:
Larger files
Explanation
Lossless advantages and disadvantages Advantages: No loss of quality, slight decreases in image file sizes. Disadvantages: Larger files than if you were to use lossy compression.
Compression, Explained. We use compression to make files smaller, so that they take up less storage space and can be downloaded more quickly.
Lossless vs. Lossy Formats.
Lossy Compression. Lossy compression is useful because of its ability to shrink a file to a more convenient size
Select the Pixel Format to be either Mono8 or BayerRG8.
Ensure ISP Enable is not selected (disabled).
From the Image Compression Mode drop-down, select Lossless.
Select the Adaptive Compression Enable checkbox to allow dynamic updates to compression tables to achieve a better compression ratio.

Explanation:
The memory of a particular microcomputer is built from 64k * 1 drams. according to the data sheet, the cell array of the dram is organized into 256 rows. each row must be refreshed at least once every 4 ms. suppose we refresh the memory on a strictly periodic basis. a. what is the time period between successive refresh requests? b. how long a refresh address counter do we need?
The time period between successive refresh requests is 0.015625 ms, and a refresh address counter with at least 16 bits is required to represent 64,000 refresh addresses.
The time period between successive refresh requests can be calculated by dividing the required refresh time (4 ms) by the number of rows in the cell array (256).
Time period between refresh requests = Required refresh time / Number of rows
= 4 ms / 256
= 0.015625 ms
Therefore, the time period between successive refresh requests is 0.015625 ms.
To determine how long a refresh address counter we need, we need to calculate the number of refresh addresses required. Since each row needs to be refreshed at least once every 4 ms, and there are 256 rows, we can calculate the number of refresh addresses required per second.
Refresh addresses per second = Number of rows / Required refresh time
= 256 / 0.004 (converted 4 ms to seconds)
= 64,000 refresh addresses per second
To determine the length of the refresh address counter, we need to find the number of bits required to represent 64,000 refresh addresses. The number of bits required can be found using the formula:
Number of bits = log2(Number of refresh addresses)
= log2(64,000)
= 15.954 bits (rounded up to the nearest whole number)
Therefore, we would need a refresh address counter with at least 16 bits to represent 64,000 refresh addresses.
In summary, the time period between successive refresh requests is 0.015625 ms, and a refresh address counter with at least 16 bits is required to represent 64,000 refresh addresses.

explain why tcp, as a byte-oriented stream protocol, is not suitable for applications such as live or real time multimedia streaming?
Acknowledgment packets slow down the speed of the TCP and are not necessary for real-time video streaming because they must be sent and received in additional time.
What is byte-oriented stream protocol?
The sender inserts bytes into a TCP connection, and the receiver reads bytes from the TCP connection since TCP is a byte-oriented protocol. TCP does not, by itself, transport individual bytes over the Internet, despite the fact that the term "byte stream" defines the service it provides to application processes.
TCP/IP and UDP are both packet-oriented protocols, however TCP/IP is stream-oriented. This means that TCP/IP is viewed as consisting of two long streams of data: one long stream of data traveling in one direction from one end of the connection to the other.
Since UDP handles each piece of data as a separate datagram, it is not a byte-stream protocol.

Question 3 Four measurements are made on each of a random sample of 500 animals. The first three variables were dif- ferent linear dimensions, measured in centimetres, while the fourth variable was the weight of the animal mea- sured in grams. The sample covariance was calculated and its four eigenvalues found to be 14.1, 4.3, 1.2, and 0.4. The eigenvectors corresponding to the first and second eigenvalues were: u [0.39 0.42 0.44 0.69] = u= [0.40 0.39 0.42 -0.72] where t denotes transpose. (a) [3 marks] Comment on the use of the sample covariance matrix for the principal components analysis for these data. (b) [3 marks] What is percentage of the variance in the original data accounted for by the first two principal components? Describe the results. CSC1933 Autumn 2022 Page 2 of 4 (c) [3 marks] The undercomplete autoencoder can be used to achieve feature extraction and dimensionality reduction. What is the relationship between the autoencoder and the principal component analysis? Draw an autoencoder that can accomplish similar task as the principal component analysis described in this question. Indicate the number of nodes at each layer of your autoencoder. (d) [4 marks] The following equation represents an infinite impulse response filter: N 3[n] = [n – 1] + y[n – 2]+Ezn]+C n=0 where z[n] is the input sample and y[n] is the output sample at time instance n; C is a constant. The notation y[n 1] indicates an output delayed by one time unit. It can be thought of as a memory. (i) By considering the equation of the filter given above, explain how it achieves the memory using the following input, z[n] = [0.5, 0.4, 0.7,0.5, 0.6, 0.4.0.8, 0.5], n = 0,...7, C = 0.1, N = 2, y[-1] = 0.0,y[-2] =0.0. [Hint: calculating y[n] up to n = 5 should be sufficient.] (ii) In what way does this filter function similarly to an LSTM cell? You need to explain how LSTM achieves "memory".
(a) The sample covariance matrix is used in principal components analysis (PCA) for these data. PCA helps to reduce dimensionality, as the goal of PCA is to find new variables (known as principal components) that are linear combinations of the original variables.
It is important to note that the sample covariance matrix requires the assumption of linearity between variables and normality of data. Additionally, PCA is most effective when there is a high correlation between variables. If there is low correlation between variables, then PCA is not useful.
As such, given that the four measurements were made on each of a random sample of 500 animals and the four eigenvalues found, it can be argued that PCA is useful in this scenario. (b) The percentage of variance accounted for by the first two principal components can be found by adding the two eigenvalues corresponding to the first two eigenvectors and dividing by the sum of all four eigenvalues.
In this case, the percentage of variance accounted for by the first two principal components would be: (14.1 + 4.3) / (14.1 + 4.3 + 1.2 + 0.4) = 0.72 or 72%. This means that the first two principal components explain 72% of the variability in the original data. This is a relatively high percentage, indicating that the first two principal components are able to capture a significant amount of the variability in the data.
(c) The autoencoder is a neural network architecture that can be used for feature extraction and dimensionality reduction. Like PCA, the autoencoder can be used to reduce the dimensionality of data by finding new variables that are linear combinations of the original variables.

imagine there are 100 miners in the bitcoin network, each of whom is capable of calculating 1024 hashes per minute. in order for the network block rate to be 1 block per 10 minutes, how many hexadecimal zeros must we require for our difficulty level?
The required number of hexadecimal zeros for the difficulty level is 7 (i.e., 4,248,294 in hexadecimal is equivalent to 7 leading zeros).
The bitcoin network uses a system called proof-of-work to secure its transactions and maintain the blockchain. Miners compete to solve complex mathematical problems by performing millions of calculations per second.
The difficulty level of the mathematical problem is adjusted by the network every 2016 blocks, or approximately every 2 weeks, to ensure that blocks are solved at a consistent rate of 1 block per 10 minutes.
To calculate the required number of hexadecimal zeros for the difficulty level, we need to use the formula:
Difficulty = (\(2^256 / Target\))
where Difficulty is the current difficulty level, \(2^256\) is the total number of possible hash values, and Target is the target hash value required for a block to be considered valid.
Since we want the block rate to be 1 block per 10 minutes, and there are 100 miners each capable of calculating 1024 hashes per minute, the total number of hashes per minute for the network is:
100 x 1024 = 102,400 hashes per minute
And the target hash value required for a block to be considered valid is:
10 minutes x 60 seconds x 102,400 hashes per minute = 61,440,000 hash values
So, the required number of hexadecimal zeros for the difficulty level can be calculated as:
Target = \(2^256 / Difficulty\)
Difficulty =\(2^256 / Target\)
Difficulty = \(2^256 / 61,440,000\)
Difficulty = \(4,248,294\)

How are the waterfall and agile methods of software development similar?
The waterfall and agile methods of software development are similar in that they both aim to develop software in an organized and efficient manner. However, they differ in the approach they take to achieve this goal.
The waterfall method is a linear, sequential method of software development. It follows a defined process with distinct phases, such as requirements gathering, design, implementation, testing, and maintenance. Each phase must be completed before the next phase can begin, and changes to the software are not allowed once a phase is completed.
On the other hand, Agile method is an iterative and incremental approach to software development. It emphasizes on flexibility, collaboration, and customer satisfaction. Agile method encourages regular inspection and adaptation, allowing for changes and improvements to be made throughout the development process. Agile methodologies, such as Scrum and Kanban, follow an incremental approach, where the software is developed in small chunks called iterations or sprints.
Both Waterfall and Agile approach have their own advantages and disadvantages and are suitable for different types of projects and teams. It is important to choose a method that aligns with the specific needs and goals of the project and the team.
