FOCAL (programming Language)
FOCAL (acronym for Formulating On-line Calculations in Algebraic Language, or FOrmula CALculator) is an interactive interpreted programming language based on ''JOHNNIAC Open Shop System'' (JOSS) and mostly used on Digital Equipment Corporation (DEC) Programmed Data Processor (PDP) series machines. FOCAL is very similar to JOSS in the commands it supports and the general syntax of the language. It differs in that many of JOSS' advanced features like ranges and user-defined functions were removed to simplify the parser. Some of the reserved words (keywords) were renamed so that they all start with a unique first letter. This allows users to type in programs using one-character statements, further reducing memory needs. This was an important consideration on the PDP-8, which was often limited to a few kilobytes (KB). Like JOSS, and later BASICs, FOCAL on the PDP-8 was a complete environment that included a line editor, an interpreter, and input/output routines. The package as a wh ...

Focal (HP-41)
The HP-41C series are programmable, expandable, continuous memory handheld RPN calculators made by Hewlett-Packard from 1979 to 1990. The original model, HP-41C, was the first of its kind to offer alphanumeric display capabilities. Later came the HP-41CV and HP-41CX, offering more memory and functionality. The alphanumeric "revolution" The alphanumeric LCD screen of the HP-41C revolutionized the way a pocket calculator could be used, providing user friendliness (for its time) and expandability (keyboard-unassigned functions could be spelled out alphabetically). By using an alphanumeric display, the calculator could tell the user what was going on: it could display error messages, such as showing ("DATA ERROR") upon attempting to divide by zero instead of simply displaying a blinking zero; it could also specifically prompt the user for arguments ("ENTER RADIUS") instead of just displaying a question mark. Earlier calculators needed a key, or key combination, for every ava ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

FOCAL (spacecraft)
FOCAL (an acronym for ''Fast Outgoing Cyclopean Astronomical Lens'') is a proposed space telescope that would use the Sun as a gravity lens. The gravitational lens effect was first derived by Albert Einstein, and the concept of a mission to the solar gravitational lens was first suggested by professor Von Eshleman, and analyzed further by Italian astronomer Claudio Maccone and others. In order to use the Sun as a gravity lens, it would be necessary to send the telescope to a minimum distance of 550 astronomical units away from the Sun, enabling very high signal amplifications: for example, at the 203 GHz wavelength, amplification of 1.3·1015. Maccone suggests that this should be enough to obtain detailed images of the surfaces of extrasolar planets. Other uses of the mission Even without using the Sun as the lens, FOCAL could perform various, otherwise impossible measurements: a separate telescope could be used to measure stellar distances by parallax, which would, using t ...

FOCAL International
FOCAL International is the trade association representing stock footage companies, post-production facilities and individuals involved in the use of footage, still images and audio in all forms of media production. It represents more than 300 companies and individuals involved in media production, asset management, preservation of historical archives, film restoration and post-production. History FOCAL International was founded in 1985 by an international group of library archive leaders, specialising in film, television and news content who knew each other largely through licensing film and television archives. The high cost of Archive management, preservation and storage and the introduction of new formats was also endangering many film based collections. The founders included Jill Hawkins from BBC Enterprises (now BBC Worldwide), Pam Turner of Visnews, David Warner of ITN, George Marshall of British Pathe, Sten Frykholm from the Swedish broadcaster SVT, Jacque Blanchard, ...

Focal Radio
Focal Radio was a commercial radio station based in the city of Stoke-on-Trent and broadcasting to the two counties of Staffordshire and Cheshire in England. The station broadcasts 24 hours a day, seven days a week via the local DAB multiplex for the city as well as online. The station's entirely locally produced programming consisted of popular music from the past 40 years along with news, sport and speech features of general interest to the local population. A number of specialist music programmes were also provided. In February 2009, the station closed down having run out of cash after just four months on air and its parent company Trent Radio Station Limited was placed into liquidation. Several weeks later, the station resumed broadcasting having been acquired by local businessman Mo Chaudry. Chaudry pulled out of backing the station three months later, resulting in an on-air pledge drive A pledge drive is an extended period of fundraising activities, generally used by p ...

Focal Neurologic Signs
Focal neurologic signs also known as focal neurological deficits or focal CNS signs are impairments of nerve, spinal cord, or brain function that affects a specific region of the body, e.g. weakness in the left arm, the right leg, paresis, or plegia. Focal neurological deficits may be caused by a variety of medical conditions such as head trauma, tumors or stroke; or by various diseases such as meningitis or encephalitis or as a side effect of certain medications such as those used in anesthesia. Neurological soft signs, are a group of non-focal neurologic signs. Frontal lobe signs Frontal lobe signs usually involve the motor system and may include many special types of deficit, depending on which part of the frontal lobe is affected: * unsteady gait (unsteadiness in walking) * muscular rigidity, resistance to passive movements of the limbs (hypertonia) * paralysis of a limb (monoparesis) or a larger area on one side of the body (hemiparesis) * paralysis head and eye movements * ...
