15-820: ICAD may refer to: ICAD (software) iCAD Inc. , a medical-device manufacturer headquartered in Nashua, New Hampshire Inhibitor of caspase-activated DNase , also called DFFA, a protein Inter-Agency Committee on Anti-Illegal Drugs of the Philippines International Committee Against Disappearances , Turkey ICAD school of learning, JEE and NEET preparing institute, based in India. International Community for Auditory Display Topics referred to by

30-530: A bit unclear. ICAD 8.3 was delivered. The recent COE Aerospace Conference had a discussion about the futures of KBE. One issue involves the stacking of 'meta' issues within a computer model. How this is resolved, whether by more icons or the availability of an external language, remains to be seen. The Genworks GDL product (including kernel technology from the Gendl Project ) is the nearest functional equivalent to ICAD currently available. ICAD provided

45-519: A declarative language (IDL) using New Flavors (never converted to Common Lisp Object System (CLOS)) that supported a mechanism for relating parts (defpart) via a hierarchical set of relationships. Technically, the ICAD Defpart was a Lisp macro; the ICAD defpart list was a set of generic classes that can be instantiated with specific properties depending upon what was represented. This defpart list

60-401: A major assembly design. One example of an application driving thousands of instances of parts is that of an aircraft wing – where fastener type and placement may number in the thousands, each instance requiring evaluation of several factors driving the design parameters. One role for ICAD may be serving as the defining prototype for KBE which would require that we know more about what occurred

75-473: Is different from Wikidata All article disambiguation pages All disambiguation pages ICAD (software) KBE, as implemented via ICAD, received a lot of attention due to the remarkable results that appeared to take little effort. ICAD allowed one example of end-user computing that in a sense is unparalleled. Most ICAD developers were degreed engineers. Systems developed by ICAD users were non-trivial and consisted of highly complicated code. In

90-843: The MIT Artificial Intelligence Laboratory for the Lisp machine and its programming language Lisp Machine Lisp , was the first programming language to include mixins . Symbolics used it for its Lisp machines, and eventually developed it into New Flavors ; both the original and new Flavors were message passing OO models. It was hugely influential in the development of the Common Lisp Object System (CLOS). Implementations of Flavors are also available for Common Lisp . New Flavors replaced message sending with calling generic functions . Flavors offers :before and :after daemons with

105-524: The end of 2001, the KTI Company faced financial difficulties and laid off most of its best staff. They were eventually bought out by Dassault who effectively scuppered the ICAD product. See IIUG at COE, 2003 (first meeting due to Dassault by KTI) The ICAD system was very expensive, relatively, and was in the price range of high-end systems. Market dynamics couldn't support this as there may not have been sufficient differentiating factors between ICAD and

120-417: The existence of ability that would exist were expectations and use reasonable or properly managed. The original implementation of ICAD was on a Lisp machine ( Symbolics ). Some of the principals involved with the development were Larry Rosenfeld, Avrum Belzer, Patrick M. O'Keefe, Philip Greenspun, and David F. Place. The time frame was 1984–85. ICAD started on special-purpose Symbolics Lisp hardware and

135-405: The lower-end systems (or the promises from Dassault). KTI was absorbed by Dassault Systemes and ICAD is no longer considered the go-forward tool for knowledge-based engineering (KBE) applications by that company. Dassault Systemes is promoting a suite of tools oriented around version 5 of their popular CATIA CAD application, with Knowledgeware the replacement for ICAD. As of 2005 , things were still

150-401: The past 15 years (much information is tied up behind corporate firewalls and under proprietary walls). With the rise of functional programming languages (an example is Haskell ) in the markets, perhaps some of the power attributable to Lisp may be replicated. Flavors (programming language) Flavors , an early object-oriented extension to Lisp developed by Howard Cannon at

165-532: The presentations at the annual IIUG (International ICAD Users Group) that have been published in the KTI Vault (1999 through 2002). Boeing and Airbus used ICAD extensively to develop various components in the 1990s and early 21st century. As of 2003, ICAD was featured strongly in several areas as evidenced by the Vision & Strategy Product Vision and Strategy presentation. After 2003, ICAD use diminished. At

195-412: The sense of end-user computing , ICAD was the first to allow the power of a domain tool to be in the hands of the user, at the same time being open to allow extensions as identified and defined by the domain expert or subject-matter expert (SME). A COE article looked at the resulting explosion of expectations (see AI winter ), which were not sustainable. However, such a bubble burst does not diminish

210-450: Was extendible via composited parts that represented domain entities. Along with the part-subpart relations, ICAD supported generic relations via the object modeling abilities of Lisp. Example applications of ICAD range from a small collection of defparts that represents a part or component to a larger collection that represents an assembly. In terms of power, an ICAD system, when fully specified, can generate thousands of instances of parts on

225-436: Was then ported to Unix when Common Lisp became portable to general-purpose workstations. The original domain for ICAD was mechanical design with many application successes. However, ICAD has found use in other domains, such as electrical design , shape modeling, etc. An example project could be wind tunnel design or the development of a support tool for aircraft multidisciplinary design.
