Recall that the Hoopoe birds are getting cancer because of the HCP retrovirus – take a look at the viral transforming gene, v-hcp compared to the c-hcp/mtk gene (above). (v-hcp lacks a ligand binding domain) Is a mAb therapy strategy likely to be useful in treating the virally-caused cancer? Briefly explain.

Transcribing Anonymous SEC Tips

Java or Python

   * The function is expected to return a STRING_ARRAY.

     * The function accepts following parameters:

     *  1. STRING_ARRAY inputNames

     *  2. STRING_ARRAY secRecords

     */

Problem Statement

Introduction

Imagine you are helping the Security Exchange Commission (SEC) respond to anonymous tips. One of the biggest problems the team faces is handling the transcription of the companies reported by the callers. You've noticed that sometimes the company name is misheard by the person taking the call, sometimes it is simply mistyped, and sometimes both. These problems make it more difficult to search the SEC records to identify the company.

You have access to the list of transcribed company names and the database of SEC records. We need a way to effectively translate company names based on their transcriptions so we can narrow our search results to the one company we are interested in.

Input

You will receive a string array representing the list of transcribed company names.

Each string in the array takes the following form:

  • The string will contain a company name comprising a set of words separated by spaces.
  • You can assume company names will only use alphabetic characters -- no numbers, no punctuation.

You will also receive a string array representing the database of SEC records.

  • Each string will be of the form ; (company name string and company EIN string separated by a semicolon). An EIN is a federal tax identification number used to uniquely identify each company.
  • As above, the company name half of the string will contain a set of words separated by spaces.
  • The EIN half of the string comprises 2 integers, a dash, and 7 more integers, in that order. Example, "12-3456789".
  • There will be no semicolons anywhere in the company name or EIN strings.

You may also make the following assumptions about the structure:

  • There will be at most 1000 companies in the SEC database.
  • There will be at most 50 company names in the input.
  • No company names or EINs will be repeated in either the input or the database.

Output

For each transcribed company name in the input string array, you want to match that to a company name (first part of a string) in the SEC database. The second part of the string in the SEC database will represent the company's EIN. Your output should also be a string array, this time representing the EINs mapped to the names in the input string array. You may assume that every input name will match a name in the SEC records.

Responding to Calls

The Basics

Let's start with the first step: making sure that if the name is transcribed perfectly, we match that company's record in the database right away. This will give you an idea of how to match company names in our system and what the output array should be. This will also show you how the input is structured if you desire to make your own custom inputs. The input comes in the form of two string arrays, where the first line represents the length of the array. An example is below.

Output

["54-1264938", "58-1481332", "19-3563561"]

Your code should pass test cases 0, 1, and 2 after solving this step.

Misspellings

The second thing we want to look for are basic misspellings due to the transcriber hearing the company name correctly but missing a keystroke or pressing the wrong key instead. Think "Harveys Steakhouse" turns into "Harfeys Sreakhouse" or "Sugar and Sugar" turns into "Sugra and Sugar". In the first example, the transcriber missed the "v" key and hit "f" instead, and missed "t" and hit "r" instead. In the second, the transcriber accidentally typed "r" before "a". You should pass test cases 3 through 8 after solving this problem. Hint: looking up the phrase "string edit distance" in a search engine should be of some help to you here.

Output

Metaphones

The last and trickiest instance of transcription comes in the form of arbitrary misspellings resulting from the transcriber either hearing the name correctly and using a different spelling than the one in our database, or mishearing the name in some form. Think "Ashley Antiques" vs. "Ashlee Antiques" vs. "Ashleigh Antiques" or "Rate My Reading" turns into "Great My Treating". This is a purposefully very open-ended and tricky problem, and you are not expected to get all cases. One example is viewable and most are purposefully hidden - try to be creative with your solution, as there are multiple ways you could solve this piece! Test cases 9 through 16 are the ones that relate to this part of the problem; as before, an example is below.

Exercises

1. A 25 kVA single-phase transformer has the primary and secondary number of turns of 200 and 400, respectively. The transformer is connected to a 220 V, 50 Hz source. Calculate the (i) turns ratio, and (ii) mutual flux in the core.

2. A 25 kVA, 2200/220 V, 50 Hz single-phase transformer’s low voltage side is short-circuited and the test data recorded from the high voltage side are P=150 W, I1 = 5A and V1 = 40 V. Determine the (i) equivalent resistance, reactance and impedance referred to primary, (ii) equivalent resistance, reactance and impedance referred to secondary.

3. A 30 kVA transformer has the iron loss and full load copper loss of 350 and 650 W, respectively. Determine the (i) full load efficiency, (ii) output kVA corresponding to maximum efficiency, and (iii) maximum efficiency. Consider that the power factor of the load is 0.6 lagging. (97.74%, 13.2 kW, 94.96%).

4. A 2.5 kVA, 200 V/40 V single-phase transformer has the primary resistance and reactance of 3 and 12 Ω, respectively. On the secondary side, these values are 0.3 and 0.1 Ω, respectively. Find the equivalent impedance referred to the primary and the secondary. (17.9ohms, 0.72ohms).

Synthetically produced ethanol is an important industrial commodity used for various purposes, including as a solvent (especially for substances intended for human contact or consumption); in coatings, inks, and personal care products; for sterilization; and as a fuel. Industrial ethanol is a petrochemical synthesized by the hydrolysis of ethylene:

C2H4 (g) + H2O (v) <=>C2H5OH (v)
Some of the product is converted to diethyl ether in the undesired side reaction:

2 C2H5OH (v)<=> (C2H5 )2O (v) + H2O (v)

The combined feed to the reactor contains 53.7 mole% C2H4, 36.7% H2O, and the balance nitrogen, and enters the reactor at 310oC. The reactor operates isothermally at 310oC. An ethylene conversion of 5% is achieved, and the yield of ethanol (moles ethanol produced/moles ethylene consumed) is 0.900. Hint: treat the reactor as an open system.

Data for Diethyl Ether:

ˆ
H of = -271.2 kJ/mol for the liquid

ˆ
Hv = 26.05 kJ/mol (assume independent of T )

Cp[kJ/(molC)] = 0.08945 + 40.33*10-5T(C) -2.244*10-7T2

(a) Calculate the reactor heating or cooling requirement in kJ/mol feed.
(b) Why would the reactor be designed to yield such a low conversion of ethylene? What processing

step (or steps) would probably follow the reactor in a commercial implementation of this process?
