CLIPS was probably the most widely used expert system tool as of 2005.[1] CLIPS itself is written in C, extensions can be written in C, and CLIPS can be called from C. Its syntax resembles that of the programming language Lisp.[2]
The use of energy is important in all sectors, considered essential in industrial, commercial and residential activities. In view of this and the environmental problems caused by energy sources with fossil fuel origin, methods of energy production with renewable sources have been increasingly addressed. Studies that estimate the impact and evaluations of solar technologies in homes are scarce. In this sense, the applied method addresses the use of CLIPS for the development of a knowledge base for preliminary diagnosis and evaluation of solar energy for homes and businesses, thus obtaining a prototype of an expert system, the method also approaches the use of artificial intelligence with a heuristic characteristic and its target audience is people with little or no knowledge in the area, thus contributing to the social impact. As a result, the developed programming helps people with little or no knowledge about solar energy and its residential application to have access and thus verify the applicability. It is worth noting that this is the first empirical study carried out in Brazil, a country of crucial importance for the development of solar energy.
For this study with regard to knowledge representation, the rule set mechanism was used, which is identified as the knowledge base. Therefore, the tool used for the development of the knowledge-based system was CLIPS, which is a rules-based programming language useful for creating expert systems and other programs where a heuristic solution is easier to implement and maintain than a algorithmic. Written in C, CLIPS can be installed and used on a wide variety of platforms. Since 1996 CLIPS has been available as public domain software (Giarratano 1996).
CLIPS is an ES tool originally developed by the Software Technology Branch (STB), NASA/Lyndon B. Johnson Space Center, and is designed to facilitate the development of software to model human knowledge or experience. There are three ways to represent knowledge in CLIPS: (1) Rules, which are primarily intended for experience-based heuristic knowledge; (2) Deffunctions and generic functions, which are primarily intended for procedural knowledge; and (3) Object-oriented programming, also aimed primarily at procedural knowledge. The five generally accepted features of object-oriented programming are supported: classes, message handlers, abstraction, encapsulation, inheritance, and polymorphism. Rules can combine patterns in objects and facts (Giarratano 1996). In CLIPS, the knowledge engineer can develop software using only rules, only objects or a mixture of objects and rules, in this work we used a mixture of objects and rules, which form an integrated system, as the rules can combine patterns in facts and objects.
The object orientation used in the study is characterized as a programming paradigm that allows the implementation of knowledge represented through frames and semantic networks, which facilitates the management and expansion of computational code and can also serve as a way of representing knowledge. It is based on four fundamental concepts: Abstraction; Heritage; Polymorphism and Encapsulation.
I'm in this predicament now, and my advice is to stay far away from option 1 as possible! I have a one hour project spanning 4 gropro clips, and syncing up my gpx data 4 different times on a short race course is a nightmare. Instead, combine your entire footage into one mp4 file using any other video editing software (Camtasia, iMovies, whatever), and THEN fire up VIRB Edit.
New to Premiere Pro. Was trying to line up a two clips in time line, both same material one with timecode burn in (of an edited sequence) and the other (unedited) without. I hit some key inadvertently and was able to see both clips side by side in the program monitor. It would be enormously helpful if I could figure out how to do this again. If anyone can help me out I would be very grateful.
If you have two clips next to each other you can do a roller trim (hold down on CTRL and drag the join) and the display will show you the in and out of both clips. A ripple trim (hold ctrl and click one side of the join) will also let you do this.
If the clips are on different tracks then you have to make one semi-transparent - using the opacity control in the effects window (ECW) - to see the other underneath. Or shrink one down using the motion parameters in the ECW. Then remember to remove

So I had this problem with Pro 19 and upgraded to 20 just to find it causing the same issue. Whenever I drag a video clip onto the timeline it adds about a quarter of a second of extra audio into the clip that isn't in the clip. The program is creating NEW audio inside of files on the timeline. After removing clips, deleting the files it creates when they are imported and dragging them back in, it does it again, but the new sound will be different. I went back and installed 17 and found there was no issue. It's as if the program is pulling audio from the clip and adding extra to the end. Why is it doing this and how do I stop it?
Ah, the issue is that it's not a specific file that has the problem. The program itself is causing the issue. It will do it to random audio clips at random points. Like if I save a project, close the program, reopen it later, a new clip will have the issue.
An overwrite edit adds a clip by replacing any framesalready in a sequence starting from the edit point and extendingfor the length of the clip. Overwrite is the default method whendragging a clip to a sequence or when rearranging clips in a sequence.
With an insert edit, adding a clip to the sequence forces any clips later in time to shift forward to accommodate the new clip. When dragging a clip, press the Ctrl (Windows) or Command (macOS) key to shift into insert mode.
If one or more tracks is locked, an insert editshifts clips in all unlocked tracks. To prevent an insert edit fromshifting clips in a track, lock the track. Alternatively, click theSync Lock button in the header of every track you want to shift.
When you add clips to a sequence by pasting, (or keyboard shortcuts), you must specify target tracks in advance. You can target more than one video track or more than one audio track at a time. Also, you can choose to target a video track only or an audio track only. Click the track or tracks you want to target in the track header area of a Timeline panel. The track header area for a targeted track appears highlighted.
If you insert a clip, the clip goes into the targeted tracks,and clips in any unlocked tracks where the source clip lands shiftto accommodate the insertion. You can specify other tracks to alsoshift by enabling Sync Lock on them.
By default, when dropped into a sequence,the video and audio components of linked clips appear in correspondingtracks (for example, Video 1 and Audio 1), unless the audio channeltype of the clip is incompatible with the target track. In thiscase, the linked audio appears in the next compatible track, ora compatible track is created automatically.
An audio clipdragged to an incompatible track automatically shifts to the next compatibletrack, even if the track is occupied by another audio clip. Therefore,take care not to disturb clips already in the sequence.
You can also drag, or Ctrl-drag (Windows) or Command-drag(Mac OS), a clip into the Program Monitor to overwrite or inserta clip. Make sure the track you want is targeted in a Timeline paneland the playhead is at the location where you want to add the clipin the sequence. To prevent an insert edit from shifting clips inany track, turn off Sync Lock for that track, or alternatively,lock the track.
Specifies how clips are placed in the sequence. If youchoose Sequentially, clips are placed one after another. If youchoose At Unnumbered Markers, clips are placed at unnumbered sequencemarkers. Choosing At Unnumbered Markers makes the Transitions optionsunavailable.
Creates an audio crossfade at each audio edit, usingthe default audio transition (defined in the Effects panel). Thisoption is available only when audio tracks are present in selectedclips, and the Placement option is set to Sequentially. It has noeffect when the Clip Overlap option is set to zero.
You can mix clips with different frame rates, frameaspect ratios, and frame sizes in the same sequence. For example,if you drop an HD clip into a sequence in an SD project, the clipwill be letter-boxed and scaled to the SD frame size automatically.Similarly, if you drop an SD clip into a sequence in an HD project,the clip will be pillar-boxed automatically.
A render bar will appear above any clip in a Timeline panel withattributes not matching the sequence settings. The render bar indicatesthat those clips will have to be rendered before final output. However,it doesn't necessarily indicate these clips can't be previewed inreal-time. If a yellow render bar appears above the clip, PremierePro can probably play it back in real time without rendering. If, however,a red render bar appears above the clip, Premiere Pro probably cannot play it back in real time without rendering.
You can replace the source footage for anyclip in the Project panel. Replacing the source footage for a cliplinks it to a new source file. All instances of the clip and itssubclips are retained in the Project panel and Timeline, with theirIn and Out points, and any applied effects, intact. However, theclip becomes linked to the replacement footage instead of its originalfootage. You can easily replace, for example, placeholder footagewith final footage, or footage with a soundtrack in one languagewith identical footage with a different-language soundtrack, and keepall the same edits that were made with the original footage.
