International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / The Technical Committee 9 (TC-9) of the Institute of Electrical and Electronics Engineers (IEEE) Instrument and Measurement Society wants to ensure that all members of the IEEE 1451 family of standards conform to a common set of basic functionality and have, at some level, a common interface. To this end, the IEEE p1451.0 working group has been chartered to prepare an overarching standard that will define the operation of the other members of the family while still leaving the physical interface up to the various other standards working groups. The IEEE p1451.0 will define the general functionality required of an IEEE 1451 transducer, a common command set that is appropriate to all family members, and the core set of transducer electronic data sheets (TEDS). This paper gives a brief overview of the overall functionality and follows that with a description of the commands and the TEDS.

"With the rapid development of the Internet, cloud gaming has increasingly gained attention. Cloud gaming is a new type of cloud service that allows a game to run on the cloud servers, and players interact with the game remotely on their own light-weight clients. There are many potential benefits for both players and game developers to deploy a game on a cloud server, such as reducing the need for clients to update the game, easing development of cross-device games and helping prevent software piracy. In this work, I developed a cloud game engine, Drizzle, with a time warp algorithm for latency compensation, and implemented a new transmission method that reduces the network bandwidth. Using Drizzle, I also developed a simple cloud game to evaluate the functionality and performance. Experiments with this game in a controlled laboratory environment provide objective measurements of game performance and subjective measurements of user performance. Analysis of the results shows Drizzle with time warp did not reduce noticeable latency but helped players get higher game scores compared to Drizzle without time warp. Moreover, Drizzle reduced network bitrates compared to some conventional cloud transmission methods."

This study investigates doctors’ and patients’ usage of three speech functions; namely statements, questions and commands in the American medical drama series House M.D. Furthermore, the study investigates interruptions between doctors and patients. The aim of the study was to ascertain whether the claim that doctors practice power over patients can be verified. The data comprises transcripts of 16 video recorded sessions of doctors and patient interacting where the material was personally collected and analyzed. In their interactions, doctors were found to dominate in making statements, asking questions and uttering commands. In addition, it was detected that the doctors’ and patients’ way to communicate differed given the fact that doctors are trained in their roles as doctors while patients are not. However, both interactants were found to perform the different speech functions similarly. The study also revealed that doctors interrupted more as compared to patients. Furthermore, gendered interruptions were found in the data, all of which came from male participants and it was concluded that the findings could be linked to the social and cultural roles of the participants. Overall, it was concluded that there exists a power relationship between doctors and patients.

This thesis describes work on using vision verification within an object level language for describing robot assembly (RAPT). The motivation for this thesis is provided by two problems. The first is how to enhance a high level robot programming language so that it can encompass vision commands to locate workpieces of an assembly. The second is how to find a way of making full use of sensory information to update the robot system's knowledge about the environment. The work described in this thesis consists of three parts: (1) adding vision commands into the RAPT input language so that the user can specify vision verification tasks; (2) implementing a symbolic geometrical reasoning system so that vision data can be reasoned about symbolically at compile time in order to speed up run time operations; (3) providing a framework which enables the RAPT system to make full use of the sensory information. The vision commands allow partial information about positions to be combined with sensory information in a general way, and the symbolic reasoning system allows much of the reasoning work about vision information to be done before the actual information is obtained. The framework combines a verification vision facility with an object level language in an intelligent way so that all ramifications of the effects of sensory data are taken account of. The heart of the framework is the modifying factor array. The position of each object is expressed as the product of two parts: the planned position and the difference between this and "he actual one. This difference, referred to as the modifying factor of an object, is stored in the modifying factor array. The planned position is described by the user in the usual way in a RAPT program and its value is inferred by the RAPT reasoning system. Modifying factors of objects whose positions are directly verified are defined at compile time as symbolic expressions containing variables whose value will become known at run time. The modifying factors of other objects (not directly verified) may be dependent upon positions of objects which are verified. At compile time the framework reasons about the influence of the sensory information on the objects which are not verified directly by the vision system, and establishes connections among modifying factors of objects in each situation. This framework makes the representation of the influence of vision information on the robot's knowledge of the environment compact and simple. All the programming has been done. It has been tested with simulated data and works successfully.

This study investigates the potential benefits and challenges of using layer 3 Internet Protocol version 6 (IPv6) configuration commands. Although any other type of layers 3 devices could have been used in this study, only Cisco routers and multilayer switches are considered. The study is conducted using a simulator called Graphical Network Simulator-3 (GNS3). Even though real Cisco Internetwork Operating System (IOS) software is reliably used in this simulator, an avoidable limitation of this method involves not using this software on real routers and multilayer switches. However, it has been found that contrary to Cisco documentation, using the outgoing local interface as next hop address causes IPv6 static routing not to work; it only works when the neighbouring global unicast address is used as the next hop address. Other findings show that when static addresses are configured with Routing Information Protocol Next Generation (RIPng), Enhanced Interior Gateway Routing Protocol version 6 (EIGRPv6) or Open Shortest Path First version 3 (OSPFv3), RIPng has the best round-trip time (RTT), while OSPFv3 gives the best traceroute results. Likewise, 64-bit Extended Unique Identifier (EUI-64) addresses produce better RTT and traceroute results with RIPng than with EIGRPv6 and OSPFv3. Nonetheless, one challenge for RIPng involves failure to start the RIPng process by misconfiguring the ipv6 router rip name and ipv6 rip name enable commands. The benefit of EIGRPv6 is that its RTT is faster than that of OSPFv3 and even if the router identifiers (router-ids) are configured the same on all the routers, the EIGRPv6 process still works well. However, configuring different autonomous system numbers and failing to configure the "no shutdown" or router-id commands results in routing challenges. On the other hand, configuring the same router-id on different layer 3 devices causes OSPFv3 not to work. In spite of this challenge, when OSPFv3 is used with Hot Standby Router Protocol version 2 (HSRPv2), it generates faster RTT than EIGRPv6 and RIPng. However, the success rate of OSPFv3 for failover time of the active router to the standby router is 4% lower than EIGRPv6. In comparison to Internet Protocol version 4 (IPv4), configuring of static and EUI-64 address commands is a very challenging task, because of the hexadecimal nature of IPv6 addresses. Despite this challenge, one benefit of these commands is the ability to use slash notation such as /64 for the prefix length. When used on dual stack commands, static addresses give better native router processing performance with no encapsulation overheads. However, configuring these addresses on dual stack commands in large networks is a challenge. With regard to manual IPv6 tunnelling, configuring the tunnel interface addresses in the same network and failure to configure the tunnel mode ipv6ip command, prevents this technique from working. Although IPv6 static Network Address Translation-Protocol Translation (NAT-PT) commands are easy to configure and to troubleshoot, the NAT-PT router raises the challenge of being a single point of failure in the network. On the whole, given these benefits and challenges, implementing IPv6 in industrial networks should not be scary. The results of this study are useful guidelines on how to efficiently design and configure IPv6 networks in a smooth way. / Dissertation (MEng)--University of Pretoria, 2016. / Electrical, Electronic and Computer Engineering / MEng / Unrestricted

<p> The design of a flexible, high speed, raster scan graphics terminal is presented. The design is presented in general architectural terms rather than from a detailed circuitry point of view.</p> <p> Control is divided between the 'main' microprocessor, an Intel 8086, and a subservient graphics controller which consists of a microprogrammable, bit-sliced, AM2903/2910 special purpose microprocessor. The high speed graphics controller is microprogrammed to accept basic line and circle generating commands. The configuration is felt to represent an efficient balance between simplicity and speed.</p> / Thesis / Master of Science (MS)
