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. -
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. -
8 December 2004 (Revised 10 January 2005) Topic: Unicode Technical Meeting #101, 15 -18 November 2004, Cupertino, California
To: LSA and UC Berkeley Communities From: Deborah Anderson, UCB representative and LSA liaison Date: 8 December 2004 (revised 10 January 2005) Topic: Unicode Technical Meeting #101, 15 -18 November 2004, Cupertino, California As the UC Berkeley representative and LSA liaison, I am most interested in the proposals for new characters and scripts that were discussed at the UTC, so these topics are the focus of this report. For the full minutes, readers should consult the "Unicode Technical Committee Minutes" web page (http://www.unicode.org/consortum/utc-minutes.html), where the minutes from this meeting will be posted several weeks hence. I. Proposals for New Scripts and Additional Characters A summary of the proposals and the UTC's decisions are listed below. As the proposals discussed below are made public, I will post the URLs on the SEI web page (www.linguistics.berkeley.edu/sei). A. Linguistics Characters Lorna Priest of SIL International submitted three proposals for additional linguistics characters. Most of the characters proposed are used in the orthographies of languages from Africa, Asia, Mexico, Central and South America. (For details on the proposed characters, with a description of their use and an image, see the appendix to this document.) Two characters from these proposals were not approved by the UTC because there are already characters encoded that are very similar. The evidence did not adequately demonstrate that the proposed characters are used distinctively. The two problematical proposed characters were: the modifier straight letter apostrophe (used for a glottal stop, similar to ' APOSTROPHE U+0027) and the Latin small "at" sign (used for Arabic loanwords in an orthography for the Koalib language from the Sudan, similar to @ COMMERCIAL AT U+0040). -

Assessment of Options for Handling Full Unicode Character Encodings in MARC21 a Study for the Library of Congress
1 Assessment of Options for Handling Full Unicode Character Encodings in MARC21 A Study for the Library of Congress Part 1: New Scripts Jack Cain Senior Consultant Trylus Computing, Toronto 1 Purpose This assessment intends to study the issues and make recommendations on the possible expansion of the character set repertoire for bibliographic records in MARC21 format. 1.1 “Encoding Scheme” vs. “Repertoire” An encoding scheme contains codes by which characters are represented in computer memory. These codes are organized according to a certain methodology called an encoding scheme. The list of all characters so encoded is referred to as the “repertoire” of characters in the given encoding schemes. For example, ASCII is one encoding scheme, perhaps the one best known to the average non-technical person in North America. “A”, “B”, & “C” are three characters in the repertoire of this encoding scheme. These three characters are assigned encodings 41, 42 & 43 in ASCII (expressed here in hexadecimal). 1.2 MARC8 "MARC8" is the term commonly used to refer both to the encoding scheme and its repertoire as used in MARC records up to 1998. The ‘8’ refers to the fact that, unlike Unicode which is a multi-byte per character code set, the MARC8 encoding scheme is principally made up of multiple one byte tables in which each character is encoded using a single 8 bit byte. (It also includes the EACC set which actually uses fixed length 3 bytes per character.) (For details on MARC8 and its specifications see: http://www.loc.gov/marc/.) MARC8 was introduced around 1968 and was initially limited to essentially Latin script only. -

Haptiread: Reading Braille As Mid-Air Haptic Information
HaptiRead: Reading Braille as Mid-Air Haptic Information Viktorija Paneva Sofia Seinfeld Michael Kraiczi Jörg Müller University of Bayreuth, Germany {viktorija.paneva, sofia.seinfeld, michael.kraiczi, joerg.mueller}@uni-bayreuth.de Figure 1. With HaptiRead we evaluate for the first time the possibility of presenting Braille information as touchless haptic stimulation using ultrasonic mid-air haptic technology. We present three different methods of generating the haptic stimulation: Constant, Point-by-Point and Row-by-Row. (a) depicts the standard ordering of cells in a Braille character, and (b) shows how the character in (a) is displayed by the three proposed methods. HaptiRead delivers the information directly to the user, through their palm, in an unobtrusive manner. Thus the haptic display is particularly suitable for messages communicated in public, e.g. reading the departure time of the next bus at the bus stop (c).

Alphabets, Letters and Diacritics in European Languages (As They Appear in Geography)
1 Vigleik Leira (Norway): [email protected] Alphabets, Letters and Diacritics in European Languages (as they appear in Geography) To the best of my knowledge English seems to be the only language which makes use of a "clean" Latin alphabet, i.d. there is no use of diacritics or special letters of any kind. All the other languages based on Latin letters employ, to a larger or lesser degree, some diacritics and/or some special letters. The survey below is purely literal. It has nothing to say on the pronunciation of the different letters. Information on the phonetic/phonemic values of the graphic entities must be sought elsewhere, in language specific descriptions. The 26 letters a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z may be considered the standard European alphabet. In this article the word diacritic is used with this meaning: any sign placed above, through or below a standard letter (among the 26 given above); disregarding the cases where the resulting letter (e.g. å in Norwegian) is considered an ordinary letter in the alphabet of the language where it is used. Albanian The alphabet (36 letters): a, b, c, ç, d, dh, e, ë, f, g, gj, h, i, j, k, l, ll, m, n, nj, o, p, q, r, rr, s, sh, t, th, u, v, x, xh, y, z, zh. Missing standard letter: w. Letters with diacritics: ç, ë. Sequences treated as one letter: dh, gj, ll, rr, sh, th, xh, zh. -
