Tilde-Arrow-Out (~→O)
Chapter 5: Derivations in Sentential Logic 181 atomic). In the next example, the disjunction is complex (its disjuncts are not atomic). Example 2 (1) (P ´ Q) → (P & Q) Pr (2) •: (P & Q) ∨ (~P & ~Q) ID (3) |~[(P & Q) ∨ (~P & ~Q)] As (4) |•: ¸ DD (5) ||~(P & Q) 3,~∨O (6) ||~(~P & ~Q) 3,~∨O (7) ||~(P ∨ Q) 1,5,→O (8) ||~P 7,~∨O (9) ||~Q 7,~∨O (10) ||~P & ~Q 8,9,&I (11) ||¸ 6,10,¸I The basic strategy is exactly like the previous problem. The only difference is that the formulas are more complex. 13. FURTHER RULES In the previous section, we added the rule ~∨O to our list of inference rules. Although it is not strictly required, it does make a number of derivations much easier. In the present section, for the sake of symmetry, we add corresponding rules for the remaining two-place connectives; specifically, we add ~&O, ~→O, and ~↔O. That way, we have a rule for handling any negated molecular formula. Also, we add one more rule that is sometimes useful, the Rule of Repetition. The additional negation rules are given as follows. Tilde-Ampersand-Out (~&O) ~(d & e) ––––––––– d → ~e Tilde-Arrow-Out (~→O) ~(d → f) –––––––––– d & ~f 182 Hardegree, Symbolic Logic Tilde-Double-Arrow-Out (~±O) ~(d ± e) –––––––––– ~d ± e The reader is urged to verify that these are all valid argument forms of sentential logic. There are other valid forms that could serve equally well as the rules in question. The choice is to a certain arbitrary. The advantage of the particular choice becomes more apparent in a later chapter on predicate logic. -
Keyboard Shortcuts for Windows Computers
AbilityNet Factsheet – May 2019 Keyboard Shortcuts for Windows computers This factsheet highlights some of the actions you can carry out quickly on your computer by using key combinations rather than using the mouse to navigate menus and options. These key combinations are referred to as shortcuts as they are often a much quicker way of carrying out tasks. They can also be particularly useful for repetitive actions.

Function Keys One of the Biggest Differences Between a Typewriter
Function Keys One of the biggest differences between a typewriter keyboard and the computer keyboard is the row of keys at the top of the keyboard that are labeled F1 through F12. Commonly referred to as Function Keys, these keys were frequently used in the good old days of DOS programs. In today’s Windows world of computers, you can probably use your computer without ever using one of these keys. Yet, these function keys provide some interesting shortcuts for common computer functions that can be useful tools in everyday computing . The function keys are frequently used in combination with other keys such as the CTRL key, the ALT key, and the Shift key. This results in a plethora of possible keyboard shortcuts . Here is a brief rundown of the function key and what they can do for you. F1 As a throwback to DOS days, you will find that the F1 key will often bring up a help menu. If you press F1 while working in a program, help for that program will usually appear. If you press F1 while at the Windows desktop or when the Windows Explorer is open, a Windows help screen will pop up . If you happen to be working in a program and would like to see the Windows help screen, simply press the Windows key (the key with the Windows logo on the bottom row of keys) on your keyboard and press F1 at the same time. F2 You can use the F2 key to rename an item when working in Windows. Highlight any folder or file, and press F2. -
Proposal to Add U+2B95 Rightwards Black Arrow to Unicode Emoji
Proposal to add U+2B95 Rightwards Black Arrow to Unicode Emoji J. S. Choi, 2015‐12‐12 Abstract In the Unicode Standard 7.0 from 2014, ⮕ U+2B95 was added with the intent to complete the family of black arrows encoded by ⬅⬆⬇ U+2B05–U+2B07. However, due to historical timing, ⮕ U+2B95 was not yet encoded when the Unicode Emoji were frst encoded in 2009–2010, and thus the family of four emoji black arrows were mapped not only to ⬅⬆⬇ U+2B05–U+2B07 but also to ➡ U+27A1—a compatibility character for ITC Zapf Dingbats—instead of ⮕ U+2B95. It is thus proposed that ⮕ U+2B95 be added to the set of Unicode emoji characters and be given emoji‐ and text‐style standardized variants, in order to match the properties of its siblings ⬅⬆⬇ U+2B05–U+2B07, with which it is explicitly unifed. 1 Introduction Tis document primarily discusses fve encoded characters, already in Unicode as of 2015: ⮕ U+2B95 Rightwards Black Arrow: Te main encoded character being discussed. Located in the Miscellaneous Symbols and Arrows block. ⬅⬆⬇ U+2B05–U+2B07 Leftwards, Upwards, and Downwards Black Arrow: Te three black arrows that ⮕ U+2B95 completes. Also located in the Miscellaneous Symbols and Arrows block. ➡ U+27A1 Black Rightwards Arrow: A compatibility character for ITC Zapf Dingbats. Located in the Dingbats block. Tis document proposes the addition of ⮕ U+2B95 to the set of emoji characters as defned by Unicode Technical Report (UTR) #51: “Unicode Emoji”. In other words, it proposes: 1. A property change: ⮕ U+2B95 should be given the Emoji property defned in UTR #51. -

The rollermouse condition was associated with a more neutral hand posture (lower Pointing device inter-fingertip spread and greater finger flexion) along with significantly lower forearm extensor muscle Computer tasks fi Musculoskeletal disorders activity. The touchpad and rollermouse, which were centrally located, were associated with signi cantly more neutral shoulder postures, reduced ulnar deviation, and lower forearm extensor muscle activities than other types of pointing devices. -

Writing Mathematical Expressions in Plain Text – Examples and Cautions Copyright © 2009 Sally J
Writing Mathematical Expressions in Plain Text – Examples and Cautions Copyright © 2009 Sally J. Keely. All Rights Reserved. Mathematical expressions can be typed online in a number of ways including plain text, ASCII codes, HTML tags, or using an equation editor (see Writing Mathematical Notation Online for overview). If the application in which you are working does not have an equation editor built in, then a common option is to write expressions horizontally in plain text. In doing so you have to format the expressions very carefully using appropriately placed parentheses and accurate notation. This document provides examples and important cautions for writing mathematical expressions in plain text. Section 1. How to Write Exponents Just as on a graphing calculator, when writing in plain text the caret key ^ (above the 6 on a qwerty keyboard) means that an exponent follows. For example x2 would be written as x^2. Example 1a. 4xy23 would be written as 4 x^2 y^3 or with the multiplication mark as 4*x^2*y^3. Example 1b. With more than one item in the exponent you must enclose the entire exponent in parentheses to indicate exactly what is in the power. x2n must be written as x^(2n) and NOT as x^2n. Writing x^2n means xn2 . Example 1c. When using the quotient rule of exponents you often have to perform subtraction within an exponent. In such cases you must enclose the entire exponent in parentheses to indicate exactly what is in the power. x5 The middle step of ==xx52− 3 must be written as x^(5-2) and NOT as x^5-2 which means x5 − 2 . -
REMOVABLE CORE) ASSEMBLY for Installation Assistance, Contact SARGENT at 800-727-5477 •
INSTRUCTIONS FOR REKEYING THE SARGENT® (65-)11-10- (6300) LARGE FORMAT INTERCHANGEABLE (REMOVABLE CORE) ASSEMBLY For installation assistance, contact SARGENT at 800-727-5477 • www.sargentlock.com The 6300 series LFIC (Removable Core) uses a control key whose bittings match the Top Master Key of the key system in positions 1, 2, 5 and 6. The control bittings in positions 3 and 4 are selected from the Key Bitting Array of the master key system. This method significantly reduces the bittings available in the Key Bitting Array of any Top Master Key. Increasing the levels in the master keying system and cross keying also has a significant impact on the yield of keys at each selected level. The chamber stack value for the 6300 series LFIC (removable core) is normally calculated by using a stack value of 15 in positions 1, 2, 5, and 6. This is the total value of the bottom pins, master splits and driver pins that would be required to pin the core (based on the keying levels). In chambers 3 and 4 of the 6300 series LFIC (removable core), the stack value is 20. This is done to allow the control key to achieve a shear line in chambers 3 and 4 of the control sleeve. Important Cylinders master keyed at the factory prior to January 2009 use hollow drivers and SARGENT recommends their continued use. Hollow drivers must be used in chambers 3 and 4. A different spring is used in conjunction with the hollow drivers. These special drivers and springs are included in a special pinning kit #437 RC/UL. -
