As the number of computing devices embedded into engineered systems continues to rise, there is a widening gap between the needs of the user to control aggregates of devices and the complex technology of individual devices. Spatial computing attempts to bridge this gap for systems with local communication by exploiting the connection between physical locality and device connectivity. A large nu...

The problem of computing the edit-distance between a string and a finite automaton arises in a variety of applications in computational biology, text processing, and speech recognition. This paper presents linear-space algorithms for computing the edit-distance between a string and an arbitrary weighted automaton over the tropical semiring, or an unambiguous weighted automaton over an arbitrary...

We give an informal presentation of the basic ideas, results, and applications of membrane computing, a branch of natural computing inspired by the structure and the functioning of biological cells, cell tissues, or colonies of cells. Membrane computing has given rise to computing models (called P systems) that are distributed and parallel, which process multisets of objects in compartments def...

We survey the current techniques to handle with the problem of parallel string matching with computing models. This is becoming a more and more relevant issue for many fast growing areas such as information retrieval and computational biology. We focus on current developments of parallel string matching, computing models, and the central ideas of the algorithms and their complexities. We presen...

We present a new computing machine, called an active element machine (AEM), and the AEM programming language. This computing model is motivated by the positive aspects of dendritic integration, inspired by biology, and traditional programming languages based on the register machine. Distinct from the traditional register machine, the fundamental computing elements – active elements – compute si...

The rapid advances in both the development and the use of parallel computing systems has led to the need for highly trained professionals with a knowledge of both the hardware and the software aspects of parallel and distributed computing. We present a course aimed at preparing students for the demands of the workplace by giving them hands-on experience working with parallel computers and softw...

26 Computer Computational Challenges of Systems Biology B ioinformatics is the computing response to the molecular revolution in biology. This revolution has reshaped the life sciences and given us a deep understanding of DNA sequences, RNA synthesis, and the generation of proteins. In the process of achieving this revolution in understanding, we have accumulated vast amounts of data. The scale...

the systematics, morphology, distribution, biology, economic importance and conservation of the freshwater eel ( anguilla anguilla ) of iran are described, the species is illustrated, and a bibliography on this fish in iran is provided. the species is found in the caspian sea basin as an exotic.

service oriented architecture (soa) technology enables composition of large and complex computational units out of the available atomic services. implementation of soa brings about challenges which include service discovery, service interaction, service composition, robustness, quality of service, security, etc. these challenges are mainly due to the dynamic nature of soa. soamay often need to ...
