Achievable rate (AR) is significant to communications. As to multi-input multi-output (MIMO) digital transmissions with finite alphabets inputs, which greatly improve the performance of communications, it seems rather difficult to calculate accurate AR. Here we propose an estimation of considerable accuracy and low complexity, based on Euclidean measure matrix for given channel states and const...

The 10-90 gap, double burden of disease, lack of infrastructure, resource scarcity: developing countries face a series of circumstances and determinants which inhibit progress in population health. Add to this constellation of challenges another set related to knowledge sharing, including the "know-do" gap and the digital divide, and the barriers to health in the Global South loom larger still....

The focus of the Japanese local telecommunications policy is moving toward how to solve the problem of the digital divide that accompanies the spread of high-speed and broadband services. This paper estimates the translog cost function of two outputs, the standard telephone service and the leased circuit service, and measures the regional gap of those stand-alone costs and incremental costs. Th...

Heterogeneous system verification lacks on functional and formal verification methodologies. A verification gap exists between the different signal domains. To bridge this gap an assertion-based design method is essential. This requires the integration of the special analog characteristics in formal digital temporal assertions. Therefore, we defined a new set of mixed-signal assertions to impro...

Recent studies that compared reading comprehension between print and digital displays found a disadvantage for digital reading. A separate line of research has shown that effective use of learning strategies and active learning tools (e.g. annotation tools: highlighting, underlining and notetaking) can improve reading comprehension. Here, the influence of annotation tools on comprehension and t...

abstract limitations of traditional (conventional) soil surveys and improvement of information technology have lead soil surveyors to invent new methods which are generally called digital soil mapping (dsm). the aim of these methods is the prediction of soil classes or soil properties based on easily-available or measuring environmental variables. the objective of this investigation is to study...

This paper presents SMIL PhotoShow, an authoring tool for photo books, which allows the creation of enhanced multimedia presentations, enriched with audio (music or spoken) comments, transition effects and animations in a very simple way. Our tool allows to create a digital counterpart of a printed photo book with the aim to bridge the gap between digital web albums and printed photo books. Sin...
