Assignment #2 – Visit the Steelcase website at:

https://www.touchboards.com/steelcase/steelcase-eno2810/ (Links to an external site.)

And read about electronic whiteboards. What advantages and disadvantages do you see in using a whiteboard during a meeting? Would you recommend purchasing this product? Explain why or why not. Draft a memo to your boss outlining your recommendations and a plan for action (tips are listed below).

TIPS FOR CREATING AN EFFFECTIVE MEMO:

Memos

When preparing a memo, you

May use a lower-grade paper than you use for letters

May be asked to use a special memo form

Include the title “Memo” (or similar) at the top of the page either centered or flush left

At the top of a memo (arranged in almost any order), place introductory information such as

To:

From:

Date:

Subject:

If a memo has wide distribution, type “See distribution list” after “To:” and place recipient names at the bottom of the page (usually in alphabetical order).

The subject line (or lines) should be short but informative.

For the body of the memo:

Start on the fourth line below heading.

Use single-spacing, with double spacing between paragraphs (unless the memo is very short).

Either indent paragraphs or make them flush left.

Head the second page just as you would head the second page of letter.

Although no complimentary close or signature block is required in a memo, the sender may initial the memo beside his or her name or at the bottom of the memo.

Handle reference initials, enclosure notations, and copy notations just as you would in a letter.

Memos may be delivered by hand, interoffice mail, or post office.

Your task is to implement an automatic language identification system that can identify… 1 answer below »

/in /by

Your task is to implement an automatic language identification system that can identify 5 written languages (English, French, German, Italian and Spanish). The system will input a text and output the language identified for this text. Assume that all words in the input text are written in the same language. The system consists of two stages: Learning and Identification. Details of the system are as follows. Stage 1: Learning languages from given text files using the n-gram technique (here n = 2, bigram). The following steps are required: • Access to a given folder named Learning and verify that it contains 5 text files which are English.txt, French.txt, German.txt, Italian.txt, and Spanish.txt. These text files are in UTF-8 format. • Do the following for each of the 5 text files: o Open the current text file, read its content, change all uppercase letters to lowercase ones, and remove non-alphabetic characters such as ~ ` ! @ # $ % ^ & * ( )
