It is important to know how the results from a land change model vary based on both the pixel resolution of the maps and the precision of the independent variables because subjective decisions or default values frequently determine these two factors. This paper presents an approach to measure the variation in model accuracy that is triggered by alteration of the pixel resolution and the precisi...

Introduction: Scatter radiation is one of the major sources of error in nuclear medicine data processing. Different methods of scatter correction have been introduced in order to improve the quality of data. However the best method is to avoid recording of scatter photons in acquisition. The only difference between scattered and non-scattered photons is the energy. Pulse height analyzer i...

Biophysical feedbacks between vegetation and sediment are important for forming and modifying landscape features and their ecosystem services. These feedbacks are especially important where landscape features differ in their provision of ecosystem services. For example, the shape of coastal foredunes, a product of both physical and biological forces, determines their ability to protect communit...

In this paper, first, an overview is given about the whole scenario of analogic CNN computing. Next, two areas on CNN Computing Technology are considered briefly: (i) the architectural advances, especially the variable resolution and adaptation in space, time, and value and (ii) the computational infrastructure from high level language and compiler to physical implementations. Three basic physi...

In this paper we examine ways to verify reference nets, a class of high level Petri nets supported by the Renew tool. We choose to restrict reference nets to hypernets, another nets-within-nets model more suitable for verification purposes thanks to an expansion toward 1-safe Petri nets. The contribution of the paper is the implementation of such analysis techniques by means of a Renew plugin. ...
