We consider frames and Bessel systems generated by iterations of the form {Ag : g ∈ G, 0 ≤ n < L(g)}, where A is a bounded linear operators on a separable complex Hilbert space H and G is a countable set of vectors in H. The system of iterations mentioned above come from the so called dynamical sampling problem. In dynamical sampling, an unknown function f and its future states Af are coarsely ...

In this paper we discuss our preliminary experiences in designing a visual system for social data analysis in collaboration between citizens and municipal authorities through a web-based open government system. Based on the integration of theoretical models with findings from formative evaluations and stakeholder workshops with a prototype system, we present a multiperspective visualization mod...

Medical records are crucial resources for every aspect of healthcare practice. The amount and complexity of the information they bear require the use of automation. In this paper we propose a method for separating and classifying the information available in medical records, drawing on Karl Popper philosophical theories. We test this method by using descriptions of clinical cases within the sco...

A Boolean network model is one of the models of gene regulatory networks, and is widely used in analysis and control. Although a Boolean network is a class of discrete-time nonlinear systems and expresses the synchronous behavior, it is important to consider the asynchronous behavior. In this paper, using a Petri net, a new modeling method of asynchronous Boolean networks with control inputs is...
متن کاملMapping Web Pages by Internet Protocol (IP) addresses: Analyzing Spatial and Temporal Characteristics of Web Search Engine Results
Internet Protocol (IP) addresses are frequently used as a method of locating web users by researchers in several different fields. However, there are competing reports concerning the accuracy of those locations, and little research has been done in manually comparing the IP geolocation databases and web page geographic information. This paper categorized web page from the Yahoo search engine in...
