I need help with the matlab question

Objective: In this experimentMatlab is used to generate approximations of a periodic square wave using the truncated Fourier series representation

Assignment: Develop a MATLAB m-file to generate a Fourier series of a square-wave in the time domain. Display the Fourier series for a square-wave based on different harmonic numbers.  Demonstrate the effects of band-limiting for a square-wave. Comment your results.

General Procedure: Write the code for an m-file (script) that will be used to generate the Fourier series representation of a square-wave. The representation should be based on a peak value of 1 V (2 V peak-to-peak) and displayed over two cycles based on a period of 1 s. Both the horizontal and vertical axes should be labeled and the graph should be given a title. The equations required are given in Table 2-2 on page 50 of the class textbook. All plots should be generated with a sufficient number of points for smooth curves. Use the title Surname_1 for the m-file. Submit your report in Blackboard as a word document file structured like this:

Pg. 2, 3, .. These pages will contain the following plots: 

   Display two cycles of the waveform for the following cases: N=1; N=3; N=5; N=7; N=9.      For each of the cases above use Matlab to plot the amplitude line spectra (one-sided). Since for this signal the phase spectra is only due to the negative sign of some of the coefficients, you can include the negative sign in the amplitude spectra and plot the coefficients with their corresponding sign. 

*you can put 2, 4 or 6 figures on a page, or arrange them as you like, just make sure that the plots are large enough to be readable. 

**after inserting all your figures you should include a paragraph of comments based on the figures presented. This paragraph can be on the same page with the last plot or on a separate page.

Pg. last This page should contain the m-file.

1-On September 1, your calendar year company rents a machine to another firm for $24,000 a year. As of December 31, $17,000 has been received and recorded in Rent Revenue. If your company uses the accrual basis, what adjusting entry do you record at year end?

debit Rent Revenue for $7,000; credit Unearned Rent Revenue for $7,000

debit Rent Revenue for $9,000; credit Unearned Rent Revenue for $9,000

debit Unearned Rent Revenue for $7,000; credit Rent Revenue for $7,000

debit Unearned Rent Revenue for $8,000; credit Rent Revenue for $8,000

debit Rent Revenue for $8,000; credit Unearned Rent Revenue for $8,000

debit Unearned Rent Revenue for $9,000; credit Rent Revenue for $9,000

2-Your company receives a $40,000 advance for a $125,000 painting job and you credit Unearned Painting Revenue. At year end, 14% of the job has been completed. If your company uses the accrual basis, what adjusting entry will you record?

debit Unearned Painting Revenue for $17,500; credit Painting Revenue for $17,500

debit Painting Revenue for $22,500; credit Unearned Painting Revenue for $22,500

debit Unearned Painting Revenue for $22,500; credit Painting Revenue for $22,500

debit Painting Revenue for $17,500; credit Unearned Painting Revenue for $17,500

I need help creating a thesis and an outline on Pacific Asian Art: The Interactions of Dynastic Cultures. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. This incident not merely made it possible for a large number of Western travelers to witness the majestic country of China than ever before. It was the source also of a dramatic contributory consequence, because of the proliferation of railways in China itself, specifically in the Northern provinces, which were the hub of the Empire in ancient ages. The disturbance of the earth due to engineering works resulted in a wealth of concrete or physical evidence of a culture previously known entirely from literary reserves. It now turned out to be probable to appreciate as never been centuries ago, not merely the literature, philosophy, and history, but as well as the art of ancient China (ibid).

On the other hand, Japanese art has been showcased in Europe in large quantities which were mostly porcelains carried by Dutch traders from Nagasaki, and oftentimes made to order for export. The art of making porcelain in Japan was learned later and never has emerged as others accomplished to be hailed nationally unique and distinctive. Some Japanese porcelain is remarkable of fine quality but they exhibit how triumphantly the Japanese can borrow from the Chinese when they are unable or unskilled to make an art of their own (Ledoux 1927). Meanwhile, for the pottery, it is a different story. Here the continental impact came prematurely, from Korea rather than from the Far East, and the pottery of Japan developed racial attributes until a greater part of it became meticulously distinctive and uphold of charisma and lure all of its own. Particular kinds remained obvious replicas of Chinese varieties, others did not. yet in neither instance does Japanese pottery somewhat equal in appearance and excellence its continental forebears. It does extremely well in a congenial manner of permitting the&nbsp.personality of the creator to materialize in his craft. In uniquely Japanese pottery one senses the individuality of the maker, a connection of communion is forged and lifeless clay appears vibrant with life.&nbsp.

Welding fumes are a common occupational exposure. Several different welding fumes can cause similar adverse health effects. Personal sampling of a welding operation at a manufacturing facility produced the following 8-hour time-weighted average (TWA) results for individual metal fumes.

Metal Fume Result OSHA PEL ACGIH TLV

Antimony 0.05 mg/m³ 0.5 mg/m³ 0.5 mg/m³

Beryllium 0.00001 mg/m³ 0.002 mg/m³ 0.00005 mg/m³ (I)

Cadmium 0.025 mg/m³ 0.1 mg/m³ 0.01 mg/m³

Chromium 0.02 mg/m³ 1 mg/m³ 0.5 mg/m³

Copper 0.03 mg/m³ 0.1 mg/m³ 0.2 mg/m³

Iron Oxide 0.5 mg/m³ 10 mg/m³ 5 mg/m³

Magnesium Oxide 0.02 mg/m³ 15 mg/m³ 10 mg/m³

Molybdenum 0.003 mg/m³ 15 mg/m³ 10 mg/m³ (I)

Nickel 0.25 mg/m³ 1 mg/m³ 1.5 mg/m³ (I)

Zinc Oxide 0.3 mg/m³ 5 mg/m³ 2 mg/m³ (R)

(R) Respirable fraction (I) Inhalable fraction Briefly summarize the primary health effects associated with overexposure to each type of metal fume, including both acute and chronic health effects. Explain what analytical methods you would use for evaluating health hazards in the workplace. Identify the types of metal fumes that would produce similar health effects on an exposed worker. Assume that each listed metal can cause respiratory irritation. Use the equation in 1910.1000(d)(2)(i) to calculate the equivalent exposure (in relation to OSHA PELS) for the metal fumes with similar health effects based on the “Result” column in the table above. Discuss whether you believe any of the individual metal fume exposures or the combined exposure exceeds an OSHA PEL or an ACGIH TLV.

Please help answer this. I would prefer someone in industrial hygiene or safety profession to answer this. Thanks.
