In this paper, we theoretically and experimentally analyze the influence of round-trip phase distributed feedback (DFB) lasers on harmonic-phase photocurrent, caused by external injection current. The results indicate that photocurrent introduced (HPIRP) reduces with increase modulation depth at a fixed frequency. Then, based HPIRP DFB laser, simple photonic generation method optical microwave ...

We analyze a month of Internet packet loss statistics for speech transmission using three different sets of transmitter/receiver host pairs. Our results indicate that packet loss is highly bursty, with the majority of individual losses occurring in a relatively small number of bursts. We find that loss exhibits dependence in most cases, but is not always wellmodeled as dependent. We introduce a...

To embrace the challenges of the mobile communication era and of the personalized travel planning aid, eTourism web portals need to evolve from the simplified perspective of pre-visit organizational tools to the wider perspective of personal travel advisors and companions, featuring useful, usable, accessible and engaging services before, during and after the travel. This paper describes some r...

Although several automatic itinerary generation services have made travel planning easy, often times travellers find themselves in unique situations where they cannot make the best out of their trip. Visitors differ terms many factors such as suffering from a disability, being particular dietary preference, travelling with toddler, etc. While most tourist spots are universal, others may not be ...

This article presents PAMELA, an annotation-based Java modeling framework. PAMELA provides a smooth integration between model and code enables developers to handle software development both at conceptual level source-code level, without transformation and/or generation, avoiding round-trip-related issues.

Despite its importance, the first image rarely figures in theories of international relations. Two conventional wisdoms explain this neglect: first, that the first image does not matter; second, that our epistemological or methodological predilections limit our ability to theorize it. Neither is true. I argue that we neglect the first image not because it is difficult to quantify or study rigor...

There is a lack of studies on trip generation rates related to land use activities in developing countries. The absence makes transportation planners listed the Institute Transportation Engineers (ITE) Trip Generation Manual, which may lead unrealistic results. study aims determine attraction for banking services Zagazig city, Egypt, and evaluate factors affecting attracted trips banks. has des...
