We address the problem of specifying and detecting emergent behavior in networks of cardiac myocytes, spiral electric waves in particular, a precursor to atrial and ventricular fibrillation. To solve this problem we: (1) Apply discrete mode-abstraction to the cycle-linear hybrid automata (clha) we have recently developed for modeling the behavior of myocyte networks; (2) Introduce the new concept...
The proliferation of mobile phones across the world, to people of all statures, has provided platform to bring computing resources to the masses. In this paper we present three mobile phone applications designed to aid the businesses and people of informal economies in developing countries. The goal of the applications is to assist in the growth of the economy through financial education and awareness...
There are over 3.5 billion mobile phones in the world and they are proliferating at astounding rates across socioeconomic and cultural boundaries. They also provide unprecedented opportunities for enabling social impact and technical activism. To most of the people in informal economies and immigrant communities, the mobile phone is the dominant computing resource which they have access to with limited...
Africa is the fastest growing mobile phone market in the world. The portfolio of available mobile phone applications that impact the populations of the continent is however limited in number and scope. Future African graduates will be the main vectors for the development of mobile applications. In this paper we present a model of teaching mobile application development for social changes emphasizing...
We present here a formal syntax and semantics for descriptive data mining. We do so in terms of three abstract models: Descriptive, Semantic, and Granular. The Descriptive Model formalizes the syntactical concepts and properties of the data mining process. Semantic Model formalizes its semantical properties. The Granular Model establishes a relationship between the Descriptive and Semantic models...
We present here a mathematical model for the Protein Secondary Structure Prediction (PSSP) problems and research. It also represents un effort to build a uniform foundations for PSSP research. The model, and hence the paper, is designed to facilitate and speed up understanding of the long standing PSSP research and its problems also for people who want to get involved in it. We present an abstract...
