Consider a solid spherical medium B with area P and density ρ. The sphere is subjected on both sides to different concentrations C, of species A to which it is permeable. The boundary surfaces at inner radius r1 to outer radius r2 are located within the solid adjacent to the interfaces, and the mole fractions of A at those surfaces are maintained at and respectively at all times. If DAB is the binary diffusivity of A through B, show through the basis that the molar fraction of species A through the sphere at can be expressed as; Ndiff,A, Sphere=4pier1r2CDab(Ya,1-Ya,2/r2-r1) and in terms of the concentration of A at the interfaces as: Ndiff,A,sphere=4pier1r2CDab(Ca,1-Ca,2/r2-r1) (b) Given inner and outer diameter of surfaces of B to be 4.68m and 4.80m respectively; moles per volume of A at the inner surface of B is 0.087 kmol/m3 and the same is negligible at the outer surface. Assuming there is no diffusion in medium B and the total molar concentration is constant, determine the mass flow rate of A by diffusion through medium B.

Extract an 8 × 8 patch from the image. To access to the (i, j)th pixel of the image, you can type Y(i,j). To access the an 8×8 patch at pixel (i, j), you can do Y(i:i+7, j:j+7) for some index i and j. Extract all the available 8 × 8 patches from the image, and store them as a 64 × K matrix where K is the number of patches. The following code will be useful.
for i=1:M-8
for j=1:N-8
z = Y(i+[0:7], j+[0:7]);
... % other steps; your job.

Here, M and N are the number of rows and columns of the image, respectively. No need to worry about the boundary pixels; just drop them.
Hint: Use the command reshape in MATLAB (and Python) to turn an 8 × 8 patch into a 64 × 1 column vector. Submit the first 2 columns and the last 2 columns of your data matrix.

2. Shauna Coleman is single. She works as an architectural designer for Streamline Design (SD).For 2018, she correctly calculated her AGI to be $107,000. However, she wasn’t sure how to compute the rest of her taxable income. She provided the following information with hopes that you could use it to determine her 2018 federal income tax return.
a. Shauna paid $4,680 for medical expenses for care from a broken ankle sustained in a biking accident. Blake, Shauna’s boyfriend, drove Shauna (in her car) a total of 115 miles so that she could receive care for the broken ankle.
b. Shauna paid a total of $3,400 in health insurance premiums during the year (not through an exchange). SD did not reimburse any of this expense. Besides the health insurance premiums and the medical expenses for her broken ankle, Shauna had Lasik eye surgery last year and she paid $3,000 for the surgery (she received no insurance reimbursement). She also incurred $450 of other medical expenses for the year.
c. SD withheld $1,800 of state income tax, $7,495 of Social Security tax, and $14,500 of federal income tax from Shauna’s paychecks throughout the year.
d. In 2018, Shauna was due a refund of $250 for overpaying her 2017 state taxes. On her 2017 state tax return that she filed in April of 2018, she applied the overpayment towards her 2018 state tax liability. She wasn’t sure but she estimated that her state tax liability for 2018 will be $2,300.
e. Shauna paid $3,200 of property taxes on her personal residence. She also paid $500 to the developer of her subdivision, because he had to replace the sidewalk in certain areas of the subdivision.
f. Shauna paid a $200 property tax based on the state’s estimate of the value of her car.
g. Shauna has a home mortgage loan in the amount of $220,000 that she secured when she purchased the home. The home is worth about $400,000. Shauna paid interest of $12,300 in interest on the loan this year.
h. Shauna made several charitable contributions throughout the year. She contributed stock in ZYX Corp. to the Red Cross. On the date of the contribution, the FMV of the donated shares was $1,000 and her basis in the shares was $400. Shauna originally bought the ZYX Corp. stock in 2008. Shauna also contributed $300 cash to State University and religious artifacts she has held for several years to her church. The artifacts were valued at $500 and Shauna’s basis in the items was $300. Shauna had every reason to believe the church would keep them on display indefinitely. Shauna also drove 200 miles doing church-related errands
i Shauna paid $250 in investment advisory fees and another $150 to have her tax return prepared (that is, she paid $150 in 2018 to have her 2017 tax return prepared).
j. Shauna is involved in horse racing as a hobby. During the year, she won $2,500 in prize money (which she is including in income) and incurred $10,000 in expenses. She has never had a profitable year with her horse racing activities, so she acknowledges that this is a hobby for federal income tax purposes.
k. Shauna sustained $2,000 in gambling losses over the year (mostly horse-racing bets) and only had $200 in winnings (which she is including in income)
Required: Determine Shauna’s 2018 taxable income starting with Adjusted Gross Income of $107,000 reported on line 7 of Form 1040 and complete page 2 of Form 1040 through Taxable Income, line 10. Also complete Schedule A, Itemized Deductions.
