follow the instructions given. please do not copy and past any thing.

you just make the slides as final presentation . and if possible give me some handwritten or rough paper from where i can read through while presenting.

A ray of non-polarized light incidents on a uniaxial calcite crystal at an angle of to the normal from the air. The optical axis has a 60 deg angle to the surface in the plane of the incident. For calcite: 0=1.65836 and =1.48641.

(a) Please calculate the separation angle between ordinary ray (o-ray) and extraordinary rage (e-ray) in terms of light energy propagation direction when

(b) Please calculate the incident angle when the separation angle between ordinary ray (o-ray) and extraordinary rage (e-ray) is zero in terms of light energy propagation direction.

A single-spaced, 7-9 pages analysis research. The main points are to address types of batteries used in EV cars, and how different types produce better effeciency.

I’m working on a chemical engineering discussion question and need an explanation to help me learn.

Liquids that boil at relatively low temperatures are often stored as liquids under their vapor pressure which at ambient temperature can be quite large. Thus, n-butane stored as a liquid/vapor system is at a pressure of 2.581 bar for a temperature of 300K. Large scale storage (>50m3) of this kind is sometimes done in spherical tanks. Give two reasons why

The following software is typically needed to create a web service:

• ASP.NET 4.0
• Visual Studio 2010
• IIS 7.5
• Microsoft SQL Server 2008 R2

For this assignment, conduct some research over the internet and create a professional document including general steps needed to create a web service.  When preparing the general steps, be sure to discuss any updated software found for which you would recommend creating a web service and why?

We are asking you to write a short document on the standards that are relevant to your part of the EcoCar project.

In engineering projects, there are usually many ways to accomplish the same task. A “standard” is a set of guidelines for how to implement a particular task that has been agreed upon by a broad set of engineers across multiple organizations within a field. The use of standards allows different organizations to create parts, devices, and systems which interoperate with one another, and allows engineers and technicians from many different backgrounds to talk about technical problems using the same language.

Standards are might be created by created by an industry consortium (e.g., the Telecommunications Industry Association (TIA) creates standards for cellular communications), a professional society such as the Society of Automotive Engineers (SAE) or Institute of Electrical & Electronic Engineers (IEEE), or a government agency (e.g., the National Institute of Standards & Technology creates many standards related to cybersecurity). They are usually developed over the course of years by committees of engineers and professionals representing a broad cross-section of effected industry.

Standard will often have to be updated with new versions because of evolving technologies. Updates to standards are also created by committees with broad representation. There is great incentive for newer versions of standards to be backwards compatible, that is to allow for new products to have additional features while ensuring that older products without those new features can still inter-operate with the newer products. Sometimes the hardest decisions made by standards committees is determining whether a new technology provides enough advantages to break with backward compatibility. You see this with the IEEE 802.11x family of standards (Wi-Fi), which allow for backwards compatibility in many but not all generations.

Note that tools or software (such as Matlab or GitHub) that are widely used are not “standards” in themselves.

For this assignment, I would like for you to write about the standards that you use in your work for the EcoCar project. One of the those standards is used by all of us: SAE J3016, the complete version of which is given at: https://saemobilus.sae.org/content/j3016_201401

For this assignment, we are asking that you research and report on SAE J3016 AND AT LEAST ONE OTHER STANDARD that is related to your work for the EcoCar project. Each of the subteams is working in areas which there are standards. For example, if your work involves the CAN bus, that is defined by ‎SAE J1939. There are other standards for electrical wiring, for safety, for software design and verification.

For your report I would like for you to:

• Cite the standard you are using
• Briefly explain what that standard covers
• Explain how the standard is applied to your work for EcoCar.

I would expect most papers would be about 2 pages in length.

. Describe concisely the chemical causes of NSA and outline methods that have been employed to prevent its occurrence. 

1. Prepare a transmittal letter for your change order proposal using the provided format.

2. Prepare a detailed cost estimate for this change using Means “Bare costs” for material, labor, and equipment. The Means excerpts provided are from 2007. Productivity rates are unchanged, but labor, material, and equipment costs must be adjusted for inflation. Assuming 3%/year inflation, adjust the costs up by (1.03)13 = 1.47. The contract allows for 10% overhead and 8% profit on change orders under $10,000. Use the provided Excel template estimating sheet.

3. Use the provided MS Project schedule to prepare a revised schedule. Create a new task “Change 01” with the duration that you estimate in question 1. Make “Change 01” parallel with the task “Windows and doors.” Make sure that you assign the Standard Calendar to the Change 01 task so that holidays will be taken into account. You can start work on the change the day after the Owner authorizes the change. What is the latest date

that you can receive the Owner’s authorization of the change order without delaying your overall schedule? 4. Explain whether this change causes any changes to the insulation, electrical, plumbing, or HVAC parts of this project. You do not have to include any costs for these items in your estimate, only discuss them and explain how you identified affected items.

5. Will any interior walls or other items have to be moved because of this change? Will this have any effect on the cost or schedule? You do not have to include any costs for these items in your estimate, only discuss them.
