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. -
CD-ROM, CD-R, CD-RW, and DVD-ROM Drives) Are the Hardware Devices That Read Computer Data from Disks
A Brief History of CD/DVD The first disc that could be written and read by optical means (using light as a medium) was developed by James T. Russell. In the late 1960s, Russell created a system that recorded, stored, and played audio/video data using light rather than the traditional contact methods, which could easily damage the disks during playback. Russell developed a photosensitive disc that stored data as 1 micron-wide dots of light and dark. The dots were read by a laser, converted to an electrical signal, and then to audio or visual display for playback. Russell's own company manufactured the first disc player in 1980, although the technology never reached the marketplace until Philips and Sony developed the technology. In late 1982, Philips and Sony released the first of the compact disc (CD) formats, which they then called CD-DA (digital audio). In the years since, format has followed format as the original companies and other industry members developed more adaptations of the original specifications. Digital Versatile disc (DVD) had its beginning in 1994, when two formats, Super disc (SD) and Multimedia CD (MMCD) were introduced. Promoters of the competing technologies failed to reach an agreement on a single standard until 1996, when DVD was selected as a convergence format. DVD has, in the few years since, grown to include variations that do anything that CD does, and more efficiently. Standardization and compatibility issues aside, DVD is well-placed to supplant CD. Magnetic vs Optical Media Optical media are storage media that hold information in digital form and that are written and read by a laser; these media include all the various CD and DVD variations, as well as optical jukeboxes and autochangers. -

Introducing Sentential Logic (SL) Part I – Syntax
Introducing Sentential Logic (SL) Part I – Syntax 1. As Aristotle noted long ago, some entailments in natural language seem to hold by dint of their “logical” form. Consider, for instance, the example of Aristotle’s being a logician above, as opposed to the “material” entailment considering the relative locations of Las Vegas and Pittsburgh. Such logical entailment provides the basic motivation for formal logic. So-called “formal” or “symbolic” logic is meant in part to provide a (perhaps idealized) model of this phenomenon. In formal logic, we develop an artificial but highly regimented language, with an eye perhaps of understanding natural language devices as approximating various operations within that formal language. 2. We’ll begin with a formal language that is commonly called either Sentential Logic (SL) or, more high- falutinly, “the propositional calculus.” You’re probably already quite familiar with it from an earlier logic course. SL is composed of Roman capital letters (and subscripted capital letters), various operators (or functors), and left and right parentheses. The standard operators for SL include the tilde (~), the ampersand (&), the wedge (v), and the arrow (→). Other operators, such as the double arrow, the stroke and the dagger, can easily be added as the need arises. The Syntax of S.L 3. A syntax for a language specifies how to construct meaningful expressions within that language. For purely formal languages such as SL, we can understand such expressions as well-formed formulas (wffs). The syntax of SL is recursive. That means that we start with basic (or atomic) wffs, and then specify how to build up more complex wffs from them. -
EXP-26 Open Frame CD Player
EXP-26 Open Frame CD Player Topics: Diode Laser, Detection of Light, CD Control System, CD Structure, Computer Control The most widespread laser applications are unambiguously the optical data storage systems such as CD, DVD and nowadays Blue-Ray disc (BD). The CD was originally designed for storage and playing back music and was later extended to the CD-ROM for computer storage. Most optical drives operate on the principle of detecting changes in the intensity of light that is reflected by the media surface. The data information is printed as so-called pits onto the reflective surface of the media. The limitation of the storage capacity is the wave length of the laser light. Light of a shorter wavelength can be focused better thus allowing higher storage density. Within this course the data detection, the control loop for the reading laser head and other components of an optical drive will be demonstrated using the open frame CD player. The optical technique to read data remains the same regardless of whether a CD, a DVD or a BD is used. Examples of Investigations: Reading assembly: A laser beam of 780 nm wavelength is focused on the CD by means of lenses L1 and L2. The spot size on the reflective layer is about 0.6 µm. The light returning from the CD is reflected by the polarizing beam splitter cube (BC) due to the action of the quarter wave plate (QWP) and is imaged on the position sensitive sensor (PSD). Detection of pits: Once the laser beam hits a pit, a change in reflected light intensity occurs due to partial scattering and destructive interference between the incoming and outgoing laser beam. -

Measure the Distance Between Tracks of CD and DVD the Aim of Work
University of Technology Department Laser & Optoelectronics Engineering Laser Eng Branch Laser application Lab. Experiment (9) Measure the Distance Between Tracks of CD and DVD The aim of work: 1-measure the distance between tracks of CD and DVD. 2-study the different between the CD & DVD. Instruments:- Laser He-Ne, CD & DVD, screen, ruler, holders Theory:- The Compact Disc was invented by Sony and Philips in 1981 in order to serve as a high-quality compact audio storage device which allowed for direct access to digital sound tracks. It was officially launched in October 1982. In 1984, the Compact Disc's specifications were extended (with the publication of the Yellow Book) so that it could store digital data. A CD (Compact Disc) is an optical disc 12cm in diameter and 1.2mm thick (its thickness may vary from 1.1 to 1.5 mm) for storing digital information: up to 650 MB of computer data (equivalent to 300,000 typed pages) or 74 minutes of audio data. A circular hole 15mm in diameter is used to centre it on the CD player's surface. A CD is built from a plastic (polycarbonate) substrate and a fine, reflective metallic film (24-carat gold or a silver alloy). The reflective layer is then covered with an anti-UV acrylic finish, creating a protective surface for data. Finally, an additional layer may be added so that data can be written on the other side of the CD as well. The reflective layer contains tiny bumps. When the laser passes over the polycarbonate substrate, light is reflected off the reflective surface, but when the laser reaches a bump, that's what allows it to encode information. -
