The workshop concludes the Research Seminar Series, which has provided a platform for disseminating the latest research activities in related technologies through its weekly seminars. The EEE courses cover a broad range of technologies and this is reflected in the variety of topics presented during the workshop. In total, thirty-three papers have been selected for the proceedings, which have been divided into seven sections. The workshop aims to be as close to a ‘real’ event as possible. Hence, authors have responded to a Call for Papers with an abstract, prior to the submission of the final paper. This has been a novel experience for many, if not all of the contributors. Clearly, authors have taken up the challenge with enthusiasm, resulting in what promises to be an interesting and informative workshop.

Agbede School of Engineering, Design and Technology University of Bradford Abstract - The telecommunications scene today seems to telecommunications and fueled the idea of Fixed Mobile be divided between fixed-line and mobile providers. This is Substitution (FMS)[2]. rather inconvenient for users who have to subscribe to The strategy to combat the exodus of traffic to wireless different providers, pay multiple bills and use different options is not a complete teardown of traditional terminals to utilize both fixed and mobile telecom services. telecommunications but the dissolution of network Subscribers want the quality of fixed services with the flexibility of mobile services. boundaries through the merger of networks, services and Fixed-Mobile Convergence (FMC) is the buzz-word that terminals via a cost-effective unified platform. This is the describes the seamless integration of fixed-line and mobile goal of Fixed Mobile Convergence (FMC)[3]. This paper telecom services as a better option to Fixed Mobile aims to give a broad overview of FMC, its enablers and Substitution (FMS) by the addition of mobility to the triple its impact on the telecommunications sector. play of voice, data and video/TV already available on fixed II.

This paper explains FMC from the three different technologies on the same platform and consequently perspectives of Terminal Convergence, Network provide the media-rich content consumers crave.

It also takes a look brings about a business makeover for the operator and a at the key facilitators for FMC such as the 3GPP-inspired IP reduction in operation costs while bringing convenience Multimedia Subsystem (IMS) and Universal Mobile Access for end users. Operators can explore new business models (UMA) which allows end-users to preserve their service via key enabling technologies while consumers can fully experience as they handover and roam when in transit experience quadruple play[4]. between networks. This paper concludes by highlighting the FMC is considered from the three perspectives of consequence of FMC to all players in the telecoms sector.

INTRODUCTION seamless access to mobile and fixed networks on an Traditionally, there has been independence in integrated platform, terminal convergence denotes a telecommunication networks, services and devices clearly single device being able to access a range of technologies operating on different platforms and under different and service convergence entails the bundled combination regulations. Fixed-line telecommunications have been of data, voice, video plus value added services. Terminal known to provide voice and data services with high convergence and service convergence concentrate on user reliability. The need to add video/TV to their services and experience and services while network convergence offer triple play offerings brought about network simplifies their operation[4]. upgrades via technologies such as fibre-optics and thus supporting broadband capabilities. The fixed-line Telco industry is massive and gets good revenue accrued from internet, Digital Subscriber Lines (DSL), hosting, provision of data transport services such as Synchronous Optical Networking (SONET) and its dedicated high capacity lines for bandwidth-hungry clients. It provides the spine for the internet and still offers the best data speeds[1]. However, great data speeds and fixed-line broadband have not been able to suppress the rapid migration to Fig.1. Successful FMC entails convergence in these areas wireless services. More and more people are being attracted by the convenience and cheap tariff offered by A.

    Articulated Nimble Adaptable Trunk Robotics Design Inc. is the leader in advanced technology costs. The ANAT robot pictured below has 8 articulations of modular robots. Our patented 1 robotic technology ANAT kinematically hyper-redundant. ANAT robot is the lightest allows the industry to be more competitive and effective for electric drive, zero backlash, articulated robot arm applications where flexibility and obstacle avoidance are available for a given reach and payload. For instance, critical. Our goal is to provide the user with maximum ANAT offer a 60-inch reach and 40 lb. continuous-duty flexibility in operation. This technology allows the robot to payload, and weigh only 100 lbs. Continuous-duty payload modify its shape according to the environment constraints, represents the maximum load that the system can handle satisfying the need of a wide range of applications for in any arm pose, indefinitely. ANAT satisfy the need of a fixed and mobile robots. The robot may have many arms; wide range of motion and dexterity through simplicity and each arm is formed by a series of identical modules, efficiency of design. all arms work in coordination. ANAT robots are currently in use After many years of R&D, Robotics Design is proud to by universities in coordination present the ANAT family. with Robotics Design.

  • July 2014 Supplement: Rescue Robotics
    CBRNE-Terrorism Newsletter July 2014 Supplement: Rescue Robotics 1 www.cbrne-terrorism-newsletter.com CBRNE-Terrorism Newsletter July 2014 Supplement: Rescue Robotics Rescue Robotics There is no doubt that Robotics will be our coworkers in the near (?) future. Especially in rescue operations and potential deadly environments. They can walk, crawl, climb, fly and dive already. They can operate into swarms, alone or indermendently and are not affected by fatigue, emotions or other disturbing factors like humans do. This special collection of articles will highlight some of the most recent advances on Rescue Robotics and their existing or future applications and possibilities. The Editor-in-Chief CBRNE-Terrorism Newsletter Robot Source: http://en.wikipedia.org/wiki/Robot The word robot can refer to both physical robots and virtual software agents, but the latter are usually referred to as bots. There is no consensus on which machines qualify as robots but there is general agreement among experts, and the public, that robots tend to do some or all of the following: move around, operate a mechanical limb, sense and manipulate their environment, and exhibit intelligent behavior — especially behavior which mimics humans or other animals. In practical terms, "robot" usually refers to a machine which can be electronically programmed to carry out a variety of physical tasks or actions. 2 KITT (a fictitious robot) is mentally ASIMO is physically anthropomorphic anthropomorphic There is no one definition of robot that satisfies everyone and many people have their own. For example Joseph Engelberger, a pioneer in industrial robotics, once remarked: "I can't define a robot, but I know one when I see one.‖ The two ways that robots differ from actual beings are, simply stated, in the domain of cognition, and in the domain of biological form.
