The classical problem of reliable point-to-point digital communication is to achieve a low probability of error while keeping the rate high and the total power consumption small. Traditional information-theoretic analysis uses explicit models for the communication channel to study the power spent in transmission. The resulting bounds are expressed using ‘waterfall’ curves that convey the revolu...

In this paper, we describe our experiences with student team projects in objectoriented software development. Object-oriented development processes are not as straightforward as, for example, traditional waterfall-like models. In objectoriented development, there is no clear border between analysis, design, and implementation. Students therefore have difficulties deciding on what to do next, ho...

With continuous changes in technology and the project management practices used to deliver successful software projects to the business and users, Information Technology leaders need to optimize and adapt to find more effective management approaches. Understanding the strengths and weaknesses of both the waterfall and agile methodologies in order to choose and blend the characteristics that ali...

Uncoded bit error probability with maximum-likelihood detection and channel capacity is derived for binary signaling on the dual antenna array channel with constrained scattering in the large system limit making use of the replica method. Examples are discussed in case of equal power for all propagation paths. In case of poor scattering (or high load), a waterfall behavior of the uncoded bit er...

geomorphologic landforms associated with tourism and development has been considered by many researchers in recent years. geomorphologic landforms which have values and capabilities, considered in context of tourism, known as geomorphosite and are studied in geomorphotourism approach. in this paper, we used landsat satellite imageries, geological and topographic maps, data obtained by field obs...
