If you are providing your own lighting, Polycom recommends using a lighting designer and having the lighting professionally installed. Lighting specifications are included in the Room Preparation Guide.Optional SeatingChairs are to be supplied by the customer or canbe purchased through Polycom. The chairsPolycom offers to accompany RealPresenceImmersive Studio Flex are:•Herman Miller Eames Executive•Steelcase Amia Task ChairThese chairs were chosen to complement thedécor of the system in both style and size. It isrecommended that chairs are the same size, colorand shape to maintain cohesiveness of the suite.For customers choosing to supply their ownchairs, the dimensions must NOT exceed:•Arm span: 24.5” [62.23 cm]•Wheel base: 27” [68.58 cm]Wall façade for decorative purposeUsed for improved aesthetics.

In order to conduct multipoint calls, you will need a multipoint server, such as Polycom RealPresence Clariti™ or RealPresence® Collaboration Server (RMX®)with the telepresence option enabled and applicable licensing as well as Polycom’s Multipoint Layout Application (MLA). The RealPresence® Distributed Media Application™ (DMA®) (included with RealPresence Clariti) for dialing is also a requirement.•Room Continuous Presence: In this standard mode, the multipoint layout will automatically be generated. All participants will be shown on the displays. The layout will be determined either by following the general principles of Polycom Immersive Telepresence multipoint or fit a custom-set view configured by the conference administrator.•Voice Activated Room Switching (VARS): VARS is different from the standard Room Continuous Presence mode in that the speaker’s site is the only site seen by others. The view of thespeaker’s site is sized to be as large as possible on all of the other participants’ displays. Thecurrent speaker sees the previous speaker’s site (i.e., the speaker’s layout remains unchanged).Layouts used in VARS are not customizable.•Active Speaker Priority (ASP): ASP mode allocates full screen real-estate to endpoints that have speaking participants. Non speaking endpoints are put in a “film-strip” in the bottom center ofeach display. Each film-strip can accommodate five endpoints. Note that ImmersiveTelepresence rooms require a frame for each codec.BandwidthThe recommended bandwidth required depends on the customer’s application, location, required resolution and other factors. Please refer to the RealPresence®Group Series Administrator’s Guide for a detailed matrix of call speeds and resolutions. Numbers are for People and Content being shared simultaneously.*Minimum network requirement may not provide an end-to-end max frame rate / highest resolutionexperience. **Other network conditions may require additional bandwidth beyond what is recommended.LAN Connection RequirementsThe customer must provide 10 sequential static IP addresses. These will be used for the Codecs, Content monitor, SoundStructure(s), Terminal Server, Display Matrix, and RealPresence Touch.A 24-port unmanaged Ethernet switch is supplied with the system. This may be replaced with a customer-preferred device of the same capacity. If an in-room switch is used, only one LAN connection on the front wall is required.Environmental Conditions•Conference room operating temperature: 41-82° F, 5-28° C•Relative humidity: 20% to 90% (non-condensing)•Ambient Noise Level: 40 dBA or lower•Recommended NC rating: NC18 to NC25Weights and Dimensions© 2017 Polycom, Inc.

This insures proper meter safety when wiring directly to high voltage systems. The unit will perform to specification on 69 Volt, 120 Volt, 230 Volt, 277 Volt and 347 Volt power systems.Unique Current Input ConnectionsEPM 2200 meter uses two current input wiring methods.• Method One - CT pass through. Directly pass the CT through the meter without any physical termination on the meter. This insures that the meter cannot be a point of failure on the CT circuit. This is preferable to utility users when sharing relay class CTs. No Burden is added to the secondary CT circuit.• Method Two - Current “Gills.” The meteradditionally provides ultra-rugged termination pass through bars allowing the CT leads to be terminated on the meter. This also eliminates any possible point of failure at the meter. This method is also a preferred technique for ensuring relay class CT integrity does not get compromised. No terminal blocks are required and this stud based design ensures that CTs will not open under a fault condition.CommunicationsThrough an optional serial Modbus communications interface, the EPM 2200 can also provide data to RTUs, PLCs and other control devices at baud rates ranging from 9600 baud to 57.6 kbaud.The EPM 2200 meter also supports optional, simultaneous BACnet MS/TP and Modbus Ethernet communications for easy integrationinto BMS and electrical monitoring systems.Method TwoNickel Plated Brass Current “Gill”CT wires terminate to meterMethod OneCT wirespass through meter (dia. 0.77” / 4.5mm)Inherently Safe DesignCurrent Input ConnectionsSolid Construction with Mounting VersatilityThe EPM 2200 has a rugged design for harsh environment.

2L670:A Flexible Adaptive Hypertext Courseware SystemPaul De Bra1Eindhoven University of TechnologyDepartment of Computing SciencePO Box513NL5600MB Eindhoven,The NetherlandsEmail:debra@win.tue.nlABSTRACTIn[4,5](among other papers)we have reported on the devel-opment of an adaptive hypertext document and system,used for learning about the subject of hypertext,through distance learning by means of World Wide Web.In the terminology of Brusilovsky’soverview paper[1],the system offered adaptive content and link hiding.This short paper briefly describes the latest developments,which include the possibility for users to choose between link hiding and link annotation.The adaptive hypertext contents consists of standard HTML(3.2)pages, which makes it easy for authors to create adaptive courses using off the shelf authoring tools.KEYWORDS:hypertext courseware,adaptive content,adap-tive hiding and annotationINTRODUCTIONAdaptive hypertext and hypermedia is an emerging research field,on the crossroad between hypermedia and intelligent user-model-based adaptive systems.Although there are many application areas for adaptive hypermedia systems,the vast majority of these systems is used for educational purposes, as intelligent tutoring systems.Based on a user-model the system generates(lists of)links to nodes(pages)the student should study in order to achieve a desired learning goal. The ELM-ART adaptive Lisp course[2]and the subsequently developed general-purpose adaptive hypertext system Inter-book[3]are typical for adaptive hypertext:the dynamically determined link structure is presented through frames(in HTML terms).Interbook presents a table-of-contents-like frame in which links are annotated to indicate which pages are suggested,advised against,or rmation pages are presented in another frame.The hypertext links that occur in these pages are also annotated,but the information content is not adaptive.This paper reports on the development of the adaptive course-ware2L670(named so for historic reasons),which features adaptive content as well as adaptive linking.Authoring for this courseware is not only simple but also familiar because it uses standard HTML.Licia CalviUniversity of Antwerp(UIA)Department of Romanic LanguagesUniversiteitsplein1B2610Wilrijk,BelgiumEmail:calvi@uia.ua.ac.beADAPTIVE CONTENTDepending on the user’s knowledge state information on a given subject may need to be presented in different ways.Stu-dents who arefirst reading about hypertext may be confused when they see the term“node”whereas the word“page”,used in the same context,would be meaningful to them,and proba-bly sufficiently accurate in an introductory text.In the course text for“2L670:Hypermedia Structures and Systems”,the use of adaptive hypertext requires that studentsfirst visit a “readme”page with instructions on how to use the course-ware and how to configure their WWW-browser.Therefore a short paragraph which tells students to go to the readme page is prominently displayed,along with a link to that page.After reading the instructions the textual content of the start-page of the course is changed automatically.The pointer to the readme page is removed from the top,and a small reminder at the bottom of the page is all that remains.Such adaptive changes to a page,using what Brusilovsky[1] calls fragment variants,are non-trivial to realize in World Wide Web,because HTML does not allow for text fragments which are condionally made visible or hidden.It would be possible to use Dynamic HTML for this purpose,but this would lead to HTML documents that are complicated(be-cause of the JavaScript or VBscript code they need to contain) and thus difficult to author.The(latest)courseware for2L670implements adaptive con-tent in HTML by means of a preprocessor thatfilters content fragments by means of conditionals encoded in structured HTML comments:<!--if definition and history-->This part appears if the two"concepts" definition and history are both known according to the user model.<!--else-->If this is not the case then this alternative is presented instead.<!--endif-->Because the comments have no“meaning”in HTML,there is no need to respect the proper nesting of conditionals and HTML tags.We give an example of the(useful)use of non-properly nested conditionals and HTML tags(in the next section).ADAPTIVE LINKINGBrusilovsky[1]distinguishesfive types of adaptive linking: direct guidance,adaptive link sorting,adaptive link annota-tion,adaptive link hiding and map adaptation.Most adaptivehypertext systems offer only one of these features.Inter-book[3]for instance concentrates on link annotation,mean-ing that desired links are marked differently from undesiredlinks,in this case by means of a colored(big)dot.The(latest)courseware for2L670supports two variations ofadaptive hiding as well as adaptive navigation. Adaptive link annotation in2L670is realized by means of link classes which are turned into different colors by usingcascading style sheets.Because of differences in author and user preferences the courseware can be configured to use any color scheme(for desired,undesired,neutral and external links)the author desires,and the user may override these choices through a“setup”HTML page and a CGI-script. Links that may be desired or undesired at times are marked in the HTML source of the pages using a link class we call “conditional”.The2L670preprocessor translates this to the classes“good”or“bad”depending on the user model. One variation of adaptive link hiding is to make the link an-chors indistinguishablefrom normal text.Undesired links are still present,but the user is not attracted to them because they look like plain text,whereas the desired(and neutral)links are clearly visible.The default setup of the courseware uses blue for desired links,purple for neutral links(which indicate that the links lead to pages with no new information because the user already visited them)and black for undesired links. Both the author and the user may configure the courseware to use link annotation or this variation of link hiding simply by replacing black by another color if desired.The second variation of adaptive link hiding,also called link removal,means that a link is made non-functional when not desired.This variation can be achieved through adaptive content,as in the following example:<!--if desired--><a href="..."><!--endif-->here is the link anchor text<!--if desired--></a><!--endif-->Note that if the conditionals were not HTML comments,but “real”tags,this construction would violate the nesting rules. AUTHORING FOR2L6702L670is different from other educational adaptive hypertext courseware in that it combines adaptiveness with“normal”hypertext functionality.A hyperdocument for2L670consists of HTML nodes and links.All features of HTML can be used by the author,including frames,scripting(with JavaScript or VBscript),Java applets,etc.In addition to hypertext function-ality some links can be annotated(or hidden)conditionally by means of the“conditional”link class,and text fragments (as small as a single word and as large as an entire page)can be conditionally included through the<!--if-->com-ments.This approach has the advantage(over other adaptive hypertext systems for the Web)that authoring can be done using standard HTML editors or word processors capable of generating HTML(with comments).Unfortunately,the2L670courseware does not eliminate the need for authors to carefully construct a didactic plan which indicates how concepts depend on each other.Each HTML page in a course starts with two structured comments:<!--requires definition and history--> <!--generates xanadu-->for instance means that links to this page are only desired when the user has learnt about the concepts“definition”and “history”,and that after reading this page the user has learnt the concept“xanadu”.The expresion in the requires clause can be any boolean expression using concept names(and possibly including subexpressions in parentheses).These two types of clauses form the basis through which an au-thor establishes the dependencies between concepts.The system automatically annotates or hides links to guide the user towards pages in an order which corresponds to the or-der the author has envisaged when creating the dependencies between concepts.1CURRENT AND FUTURE DEVELOPMENTSThe2L670courseware is currently being used for the course “Hypermedia Structures and Systems”(initiallywith the code 2L670)which is offered to students at six universities in The Netherlands and Belgium.It is also used in a course on Graph-ical User-Interfaces.The software for the courseware is freely available upon demand.It consists of two(Fast-)CGI scripts written in Java and a few wrapper shell scripts.Apart from adaptive hypertext distance education requires additional sup-port,like a message board(for which we use HyperNews), multiple-choice tests(for which the2L670courseware also offers support),and upload facilities for assignment work (for which we plan to use the DReSS document repository system).REFERENCES1.Brusilovsky,P.,Methods and Techniques of AdaptiveHypermedia,User Modeling and User-Adapted Interac-tion6,Kluwer academic publishers,pp.87–129,1996.2.Brusilovsky,P.,Schwarz,E.,Weber,G.,ELM-ART:Anintelligent tutoring system on World Wide Web,Proc.of the Third International Conference on Intelligent Tutor-ing Systems,ITS-96,Montreal,1996.(Lecture Notes in Computing Science,vol.1086,pp.261–269).3.Brusilovsky,P.,Schwarz,E.,Weber,G.,A Tool for De-veloping Adaptive Electronic Textbooks on WWW,Proc.of the WebNet’96Conference,pp.64–69,San Francisco, 1996.4.Calvi,L.,De Bra,P.,Improving the Usability of Hyper-text Courseware through Adaptive Linking,Proc.of the ACM Conference on Hypertext,pp.224–225,Southamp-ton,1997.5.De Bra,P.,Calvi,L.,Creating Adaptive Hyperdocumentsfor and on the Web,Proc.of the AACE WebNet’97Con-ference,pp.149–154,Toronto,1997.。
