Step 1: Select Your Ideal Design Career

Now that you have had a chance to consider various careers in design, take a moment to consider which one is right for you by writing a blog post or journal entry. Review the lessons and determine which of the careers described best fits your interest in the design industry. If the career you have in mind is not mentioned in the unit, you can still write about it. Just be sure to include details about that career and the talents you have that make it a good fit. Also include details about job responsibilities and salary. You may need to do research on the internet to find facts and details.

Step 2: Describe Your Ideal Day at Work

Sometimes envisioning a goal can help you reach that goal. In the second paragraph, describe what an ideal day at work would look like in your design career. What skills and talents would you use? What difficulties might you overcome?

Step 3: Explain How You’ll Get There

In the third paragraph, describe what steps you can take, both right now and in the future, to achieve the career you want. Is there a youth organization related to fashion that you could join or start? Is there a professional organization that could provide you with information? Is there a college major you could pursue or a training program you could sign up for? What about a job, internship, or apprenticeship? Look for local education programs or organizations that could help you, and list whichever ones you are able to find.

An economy consists of three workers: Larry, Moe, and Curly. Each works 10 hours a day and can produce two services: mowing lawns and washing cars. In an hour Larry can either mow one lawn or wash one car; Moe can either mow one lawn or wash two cars, and Curly can either mow two lawns or wash one car.

a. Calculate how much of each service is produced under the following circumstances, which we label A, B, C, and D:

• All three spend all their time mowing lawns. (A)
• All three spend all their time washing cars. (B)
• All three spend half their time on each activity. (C)
• Larry spends half his time on each activity, while Moe only washes cars and Curly only mows lawns. (D)

b. Graph the production possibilities frontier for this economy. Using your answers to part (a), identify points A, B, C, and D on your graph.

c. Explain why the production possibilities frontier has the shape it does.

d. Are any of the allocations calculated in part (a) inefficient? Explain.

Universal hashing is a technique used in computer science and cryptography to design hash functions that minimize collisions and provide good average-case performance. The idea is to randomly select a hash function from a family of hash functions, ensuring that the probability of collisions is low for any given input set. Here's an overview of how universal hashing works:

1. Hash Function Family: Define a family of hash functions, denoted as H, that can be used to hash the keys. Each hash function in this family maps keys to hash values.

2. Random Selection: When you want to hash a key, you randomly select a hash function from the family H. This random selection introduces an element of randomness that helps distribute the keys more uniformly.

3. Collision Probability: The key to the effectiveness of universal hashing is to ensure that the probability of collisions (i.e., two different keys hashing to the same value) is low for any input set of keys. This is achieved by carefully designing the hash function family.

4. Analysis: Universal hashing relies on probabilistic analysis to demonstrate that the chosen hash function family provides good average-case performance in terms of minimizing collisions.

To solve or implement universal hashing, you need to perform the following steps:

Step 1: Define Hash Function Family Choose a prime number p and define a hash function family H. For each a and b where a is in the range [1, p-1] and b is in the range [0, p-1], define a hash function h_{a,b}(k) as:

Where:

• k is the input key.
• p is a prime number that determines the range of the hash function.
• m is the number of slots or buckets in the hash table.

Step 2: Random Selection For each key you want to hash, randomly choose a and b from the allowed ranges. This random selection is typically done using a truly random source or a pseudorandom number generator.

Step 3: Hashing Given a key k, and the selected a and b, calculate the hash value using the formula mentioned earlier.

Step 4: Collision Analysis To analyze the collision probability, you can use techniques from probability theory and number theory. The goal is to show that for any distinct keys k1 and k2, the probability that h_{a,b}(k1) = h_{a,b}(k2) is small, ideally close to 1/m (where m is the number of buckets).

Step 5: Usage Use the selected hash function to hash keys in your hash table. Remember to re-randomize the a and b values whenever you rehash or resize the hash table.

It's important to note that implementing universal hashing requires a good understanding of number theory, probability, and hash functions. The effectiveness of the technique relies on the careful choice of parameters and the quality of the hash function family H. Universal hashing is often used in situations where security and performance are both important, such as in cryptographic applications or hash-based data structures.

You received an unsolicited proposal from a self-declared inventor who is seeking investors for the development of his latest idea: a device that uses heat extracted from the ground by heat pump to boil water into steam that is used to heat a home and to power a steam engine that drives the heat pump. This procedure is potentially very lucrative because after an initial extraction of energy from the ground no fossil fuels would be required to keep the device running indefinitely. Would you invest in this idea? State your conclusion clearly and present detailed arguments to support it.
