Cable termination faults are problematic in electrical networks almost always. Technology has solved problems somewhat, but there are many annual reports about damaged cable terminations. For analyzing the problems, faults in two regional electricity companies are studied. At first step, damaged cable terminations are analyzed statistically and grouped according to their problems. Then, some of...

During the late 1990s, Jamaica’s telecommunications industry was poised for growth with an increased demand for new telecommunication services. At this time however, there was only one player, Cable and Wireless Ja. Ltd, which had a monopoly licence until the year 2013. However, this licence was revoked in 1999, bringing new players to the market, such as Digicel and Claro which revolutionised ...

Advancements in telecommunication services and networking, have remarkably improved information communication services. The growing need of proper and secure communication is based on using appropriate communication technologies to work effectively and efficiently to meet the objectives of the information users. For some time this has been a great problem. For example, if one element e.g. a cab...

The essential requirements for establishing a low-loss and high-speed telecommunication line using optical fibers are high performance and quality splicing technology. The simple connection of optical fibers using optical connectors and mechanical splices is increasing. However, the fusion splice is needed for long-haul and high-capacity trunk communications such as submarine optical fiber cabl...

We report on our experience in telementoring during laparoscopic adrenalectomy. An experienced laparoscopic surgeon supervised a less experienced surgeon from a control room about 100 meter away. Mentoring was accomplished over a fiber optic cable employing real-time video imaging, two-way audio communication, OES ImageTrac Video System used to control the laparoscopic image, and a telestrator....

This paper deals with RC active biquad working in the so-called current mode (CM). The design approach uses only three transconductors (OTA) with the minimum necessary number of outputs and with only three passive grounded elements. The proposed filter has simple circuit configuration providing all standard transfer functions such as high-pass (HP), band-pass (BP), low-pass (LP), band-reject (B...

In this study, nonlinear vibration of a composite cable is investigated by considering nonlinear stress-strain relations. The composite cable is composed of an aluminum wire as reinforcement and a rubber coating as matrix. The nonlinear governing equations of motion are derived about to an initial curve and based on the fundamentals of continuum mechanics and the nonlinear Green-Lagrangian stra...

The convergence of telecommunication, cable TV, and broadcast networks towards the Internet technology will enable the provision of emerging multimedia services as well as the integration of rich communication capabilities with TV services. However, enabling efficient delivery of interactive personalized multimedia services with mobility support requires an advanced overlay control framework. T...

This paper addresses voltage control of distributed dc power systems. DC power systems have been discussed as a result of the introduction of renewable, small-scale power generation units. Also, telecommunication power systems featuring UPS properties might benefit from a broader introduction of dc power systems. Droop control is utilized to distribute the load between the source converters. In...

Wireless access in hybrid fiber/coax (HFC) networks can integrate two major telecommunication infrastructure, i.e., wireless and HFC networks. This paper studies the technical feasibility of integrating IS-95 code-division-multiple-access (CDMA) wireless networks and HFC networks. Capacity estimation of an HFC optical node-based CDMA cellular systems using a return-path channel model is provide...
