please answe these 2 topic

Topic 1: Electromagnetic Waves
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
According to your Knowledge, answer the following questions:
- Describe the characteristic of Electromagnetic Waves?
- Radio Waves travel along different paths:
a. State their names?
b. Which of them does Loran-C receiver receive?

Topic 2: Loran-C and e-Loran Systems
Two navigation systems that produce position through the measurement of the difference in times of radio signals from two or more synchronized transmitters at fixed points. Such systems require the use of a receiver, which measures the time difference.
According to your Knowledge, answer the following questions: (Within 600 words)
A. Define the Coding delay and the Group Repetition Interval in loran-C system and
mention their benefits?
B. Mention8pointsascommonpointsbetweenLoran-Cande-LoranSystems? C. State6pointsasdifferentpointsbetweenLoran-Cande-LoranSystems?

Summarize IFRS/GAAP differences from the following:

Differences • Presentation of the income statement under GAAP follows either a single-step or multiple-step format. IFRS does not mention a single-step or multiple-step approach.
• Under IFRS, companies must classify expenses by either nature or function. GAAP does not have that requirement, but the SEC requires a functional presentation.
• IFRS identifies certain minimum items that should be presented on the income statement. GAAP has no minimum information requirements. However, the SEC rules have more rigor-ous presentation requirements.
• IFRS does not define key measures like income from operations. SEC regulations define many key measures and provide requirements and limitations on companies reporting non-GAAP/ IFRS information.
• Under IFRS, revaluation of property, plant, and equipment, and intangible assets is permitted, with gains reported as other comprehensive income. The effect of this difference is that applica-tion of IFRS results in more transactions affecting equity but not net income.

A certain drug induces sleep in 80% of people who consume it. One researcher argues that if it is mixed with another newly developed drug the percentage of effectiveness would be higher. To determine if he is right, he independently selects a random sample of 16 patients and records the number Y of cases in which the mixture induced sleep. The hypotheses for this test are:

H_0 ∶p = 0.80
 
H_a ∶p> 0.80
where p is the proportion of patients in which the mixture of drugs under study induces sleep.
a. If it is decided that the null hypothesis will be rejected if Y≥14, calculate the significance level α for this test.
b. The experiment is carried out and it is obtained that in y = 13 patients the drug mixture induces sleep.
    1.Calculate the p-value of this test.
    2.Infer if the null hypothesis is rejected and why, also mention what type of error could be made according to the inference.
c. Assuming that the true proportion of patients in which the drug mixture induces sleep is p = .85, calculate β, the probability of making a type II error.

You recently started an entry-level job in sales and customer service at a large Canadian telecom company. You were told by your manager that your company is offering a free, 30 day trial of “Fibe Alt TV,” and that you should be suggesting this to customers you talk to. However, you soon learn that this is not in fact a trial, and that customers only receive a free month if they continue the service. You believe that your manager is encouraging sales associates to intentionally mislead customers. You’ve talked with a friend at the company, and she has similar concerns. Imagine you want to raise your concern at your workplace, either to your manager or to someone else at the company.

Drawing on the work of Mary Gentile, specify and explain 2 rationalizations you may possibly encounter. How could you use knowledge of the ways our decision-making can be biased to better craft your response? This part of your answer should mention and explain at least 2 decision-making biases that Gentile considers.

I have been assigned a 3 page research paper into "active investment strategy" versus "passive investment strategy".

Our course's textbook has no direct mention of either after searching exhaustively, which means the research paper invites me to use other sources and any perspectives or angles to defining, giving examples of, and comparing the two strategies.

How would you define them? What topics would they encompass? I imagine passive strategies include ones with fewer steps and less oversight/watch needed, whereas active strategies involve any marketable securities like stocks where you might have to be making all sorts of security analysis and stock market watching. This is for a Fundamentals of Financial Management MBA course that basically goes over every kind of marketable security and every kind of asset.

Do you recommend any sources or databases or academic searches to make this concise 3 page paper?

Thank you for your time and help!

Scenario Question.

Omani company for investment ( OCI ), is one of the biggest business company in Oman, it has diverse varieties of investment, one of these businesses is an old tower building, 20 floors located in Seeb area used as offices by multiple companies.

OCI decided to change the purpose of the building to a residential building, so it started to plan to demolish the building through one of its construction company.

The location description of the building is located in a very crowded area, the main gate of the building opening to the main road in the North direction, East and West directions of the building attached to two buildings, the South direction of the building is next to a wadi. after the company communicated its plan to all governmental authorities, the municipality requested that the work should be finish in a very short time due to the nature of the area.

Task's questions:

1/ Identify which suitable technique of demolition that the company has to follow and why?

2/ Mention all the important precautions that should be taken by the demolition contractor.

3/ Discuss the method statement of the demolition operation.

We assume a superscalar pipeline capable of fetching and decoding two instructions at a time, having two separate functional units (e.g., one integer arithmetic and one floating-point arithmetic), and having two instances of the write-back pipeline stage. Assume the following constraints on a six-instruction code fragment:

Inst-1 is a floating point operation

Inst-2 requires two cycles to execute and depends on output of Inst-1

Inst-3 and Inst-4 conflict for the same functional unit. Inst-3 and Inst-4 are floating point operations.

Inst-5 is an Integer operation

Inst-5 and Inst-6 conflict for a functional unit.

Integer operations can be performed on integer or floating point unit whichever found available but floating point operations must require floating point unit.

Show the states of different stages of superscalar processor at different clock cycles for any instruction issue policy. Please mention the policy you use to answer the question.
