Design elements - UML use case diagrams

The vector stencils library "UML use case diagrams" contains 25 symbols for the ConceptDraw PRO diagramming and vector drawing software.
"Use case diagrams are usually referred to as behavior diagrams used to describe a set of actions (use cases) that some system or systems (subject) should or can perform in collaboration with one or more external users of the system (actors). Each use case should provide some observable and valuable result to the actors or other stakeholders of the system. ...
Use case diagrams are in fact twofold - they are both behavior diagrams, because they describe behavior of the system, and they are also structure diagrams - as a special case of class diagrams where classifiers are restricted to be either actors or use cases related to each other with associations. ...
Use case is usually shown as an ellipse containing the name of the use case. ...
Name of the use case could also be placed below the ellipse. ...
If a subject (or system boundary) is displayed, the use case ellipse is visually located inside the system boundary rectangle. Note, that this does not necessarily mean that the subject classifier owns the contained use cases, but merely that the use case applies to that classifier. ...
A list of use case properties - operations and attributes - could be shown in a compartment within the use case oval below the use case name. ...
Use case with extension points may be listed in a compartment of the use case with the heading extension points. ...
A use case can also be shown using the standard rectangle notation for classifiers with an ellipse icon in the upper right-hand corner of the rectangle and with optional separate list compartments for its features. ...
Subject (sometimes called a system boundary) is presented by a rectangle with subject's name, associated keywords and stereotypes in the upper left corner. Use cases applicable to the subject are located inside the rectangle and actors - outside of the system boundary. ...
Standard UML notation for actor is "stick man" icon with the name of the actor above or below of the icon. Actor names should follow the capitalization and punctuation guidelines for classes. The names of abstract actors should be shown in italics. ...
Custom icons that convey the kind of actor may also be used to denote an actor, such as using a separate icon(s) for non-human actors. ...
An actor may also be shown as a class rectangle with the standard keyword «actor», having usual notation for class compartments ...
An actor can only have binary associations to use cases, components, and classes. ...
An association between an actor and a use case indicates that the actor and the use case somehow interact or communicate with each other.
Only binary associations are allowed between actors and use cases.
An actor could be associated to one or several use cases. ...
A use case may have one or several associated actors." [uml-diagrams.org/ use-case-diagrams.html]

The vector stencils library "Media" contains 36 multimedia, audio, video, photo icons. Use this media icon set to design your computing and telecom illustrations and infographics with ConceptDraw PRO diagramming and vector drawing software.
"Multimedia is content that uses a combination of different content forms such as text, audio, images, animation, video and interactive content. Multimedia contrasts with media that use only rudimentary computer displays such as text-only or traditional forms of printed or hand-produced material.
Multimedia can be recorded and played, displayed, dynamic, interacted with or accessed by information content processing devices, such as computerized and electronic devices, but can also be part of a live performance. Multimedia devices are electronic media devices used to store and experience multimedia content. Multimedia is distinguished from mixed media in fine art; by including audio, for example, it has a broader scope. The term "rich media" is synonymous for interactive multimedia. Hypermedia scales up the amount of media content in multimedia application." [Multimedia. Wikipedia]

A new app named Health and a corresponding framework named HealthKit will be available. Siri will support hands-free activation and music identification using Shazam. Voice and video messages will be automatically deleted unless the user saves them for future reference. Interactive notifications will let the user respond to texts without leaving the app they are currently using." [iOS 8. Wikipedia]

"Wheelchair curling is an adaptation of curling for athletes with a disability affecting their lower limbs or gait. Wheelchair curling is governed by the World Curling Federation, and is one of the sports in the Winter Paralympic Games.
Wheelchair curling is played with the same rocks and on the same ice as regular curling, though the rocks are thrown from a stationary wheelchair and there is no sweeping. Rocks may be thrown by hand while leaning over the side of the wheelchair, or pushed by a delivery stick. This is a pole with a bracket that fits over the rock handle, allowing the rock to be pushed while applying correct rotation. ...
Wheelchair curling began in Europe in the late 1990s and in North America in 2002. The first World Wheelchair Curling Championship was held in Sursee, Switzerland in 2002, and was won by the host nation who beat Canada 7 - 6 in the final. It started as a Paralympic sport at the 2006 Winter Paralympics in Turin, Italy." [Wheelchair curling. Wikipedia]
