As variety of applications and services that can be provided on packet switched networks has strongly increased over the last years and keeps on increasing, the need for an accurate network monitoring has become an important challenge to be dealt with accurately. Among the different parameters that can be considered for the traffic monitoring on a path, this paper focuses the attention on the a...

Although mobile phone usage has proliferated in urban areas of developing countries, many rural or poor users remain completely unconnected, particularly in Africa. In this paper, we advocate an alternative “voice message mostly” mobile phone architecture to reach the next billion users. Using initial analyses of mobile phone usage and rural power data, we outline the potential benefits of swit...

This paper describes the benefits of using controlled switching technology on medium voltage circuit breakers. Although this technology has been used on high voltage networks for over 30 years, recent technological advances have permitted the development of a new generation of controlled switching devices for medium voltage. This paper reviews controlled switching device approaches, describes m...

Prognostics is seen as a key component of health usage monitoring systems, where prognostics algorithms can both detect anomalies in the behavior/performance of a micro-device/system, and predict its remaining useful life when subjected to monitored operational and environmental conditions. Light Emitting Diodes (LEDs) are optoelectronic micro-devices that are now replacing traditional incandes...

Emerging feature dense portable microelectronic devices pose several challenges, including demanding multiple supply voltages from a single miniaturized power-efficient platform. Unfortunately, the power inductors used in magnetic-based switching converters (which are power efficient) are bulky and difficult to integrate. As a result, single-inductor–multiple-output (SIMO) solutions enjoy popul...

This work describes a distributed technique to dynamically determine the state of an optical Banyan switching network that will provide the paths requested by a parallel application.

Code-switching is commonly used in the free-form text environment, such as social media, and it is especially favored in emotion expressions. Emotions in codeswitching texts differ from monolingual texts in that they can be expressed in either monolingual or bilingual forms. In this paper, we first utilize two kinds of knowledge, i.e. bilingual and sentimental information to bridge the gap betw...

Over the past few years, the Internet traffic has grown rapidly and the optical transport bandwidth has been continuously increasing. These changes are stimulating the evolution of data networks. In such a dynamic environment, a network architecture that accommodates multiple data formats, supports high throughput, and is capable of flexible bandwidth provisioning is the key to the design and d...

Many methods for finding the optimal design of an optical packet switching ring network are without the performance guarantees, leading to the unexpected network behavior in terms of the QoS performance that network offers to its clients. The inter-dependability between the network QoS performances and the cost optimal design of an optical packet switching ring with a single tunable transmitter...

This paper discusses key results in the field of high speed optical networking with particular focus on packet-based systems. Schemes for optical packet labeling, packet switching and packet synchronization will be discussed, along with schemes for optical clock recovery, channel identification and detection of ultra-high-speed optical signals.
