We present DESAL(alpha), a realization of the Dynamic Embedded Sensor-Actuator language for Telos-based devices. The platform provides native support for (i) rule-based programming, (ii) synchronized action scheduling, (iii) neighborhood management, and (iv) distributed state sharing. We describe the design and implementation of DESAL(alpha), present examples that illustrate its use, and summarize the resource requirements of compiled applications. Finally, we present lessons learned based on our use of DESAL(alpha) during the past year.

Although there are certain '' preferred '' languages for real-time system design, such as C, C++, Ada 95, and increasingly Java, many real-time systems are still written in Fortran, assembly language, and even Visual BASIC. The purpose of this article is to synthesize the theoretical basis of real-time distributed systems in order to facilitate the definition and implementation a new programming language dedicated for this kind of systems.

This paper describes the design of Monty, a language intended to be equally suitable for both scripting and conventional programming. Monty features an unusually flexible type system in which all values are viewed as objects in a single-inheritance class hierarchy, static and dynamic typing are smoothly integrated, and both nonvariant and covariant generic classes are supported. An interesting by product of the design of Monty has been the light it has shed on the power of mutability as a linguistic concept. Among other things, it turns out that the type-soundness of a covariant generic class is closely related to the class's mutability.

Because enriching grid applications is crucial to promote grid computing and grid economy, in this paper we focus on how to attract expert system programmers to run their applications on grid systems. CLIPS is a rule-based language designed to help construct expert systems more easily because it is not required to design all algorithm to solve any problem. Instead, it relies oil the CLIPS inference engine to draw a conclusion from the known facts and rules. However. because Of the language's characteristics. it is very time-consuming to execute a CLIPS application when compared with other algorithmic languages. To address the problem, we propose to execute a CLIPS-based expert system in parallel by emerging cluster and grid systems in this paper. To achieve the goal, CLIPS has to be extended with new syntax to be a parallel version. In addition, we propose to adopt the SPMD computational model for programming to maintain parallel CLIPS applications in an easier way. According to experimental results. it is appealing to run CLIPS-based expert systems in parallel oil Cluster and grid systems by adopting our approach because the performance improvements can be superlinear.

Level - Beginner, but attendees should have some experience with a high-level programming *** tutorial is designed for those who have some familiarity with a programming language, but who are new to Ada. In the morning, we will discuss the basics of programming in Ada, including types, packages, syntax rules, and other Ada programming constructs. In the afternoon, we will cover Ada's object-oriented programming and concurrent-programming features. Many examples will be shown; freely downloadable Ada programming environments and tools will be demonstrated.

"This work strikes a balance between the pure functional aspects of F# and the object-oriented and imperative features that make it so useful in practice, enable .NET integration, and make large-scale data processing possible."—Thore Graepel, PhD, Researcher, Microsoft Research Ltd. Over the next five years, F# is expected to become one of the world's most popular functional programming languages for scientists of all disciplines working on the Windows platform. F# is free and, unlike MATLAB® and other software with numerical/scientific origins, is a full-fledged programming language. Developed in consultation with Don Syme of Microsoft Research Ltd.—who wrote the language— F# for Scientists explains and demonstrates the powerful features of this important new programming language. The book assumes no prior experience and guides the reader from the basics of computer programming to the implementation of state-of-the-art algorithms. F# for Scientists begins with coverage of introductory material in the areas of functional programming, .NET, and scientific computing, and goes on to explore: Program structure Optimization Data structures Libraries Numerical analysis Databases Input and output Interoperability Visualization Screenshots of development using Visual Studio are used to illustrate compilation, debugging, and interactive use, while complete examples of a few whole programs are included to give readers a complete view of F#'s capabilities. Written in a clear and concise style, F# for Scientists is well suited for researchers, scientists, and developers who want to program under the Windows platform. It also serves as an ideal supplemental text for advanced undergraduate and graduate students with a background in science or engineering.

Serial analysis of gene expression (SAGE) is a powerful technique for measuring global gene expression through sampling of transcript tags. SAGE tag collections or libraries serve as a rich data source for differential gene expression analysis, transcriptome mapping, and gene discovery. Transcriptome mapping and gene discovery are facilitated by extensions of SAGE, e.g., Long SAGE, where the transcript tags are elongated by utilization of a different tagging enzyme. SAGE, as a sequencing-based technique, is prone to errors resulting in artifact SAGE tag sequences and erroneous tag numbers. A methodology to pinpoint and correct tag artifacts is necessary to fully exploit the value of large SAGE libraries. SAGEScreen is a tag sequence correction algorithm. The algorithm is a multistep procedure that addresses error rates and performs ditag and tag processing. The error rate estimates are based on a stochastic model of PCR and sequencing related mutations. The ditag processing step is essential for calculation of unbiased tag numbers, and the tag processing step allows for filtration of tag sequence artifacts and adjustment of tag numbers. less

As transposomics is extended to genome scale, appropriate statistical methods need to be developed to assign significance to gene essentiality. In this chapter, the author presents a set of steps that, together with genome-scale insertion data and the complete genome sequence of a prokaryote, can be used to classify the genes of the organism as either “essential” or “nonessential.” less

The secondary structure of most functional RNA molecules is strongly conserved in evolution. Prediction of these conserved structures is therefore of particular interest when studying noncoding RNAs. Moreover, structure predictions on the basis of several sequences produce much more accurate results than energy directed folding of single sequences. The RNAalifold program predicts the consensus structure for a set of aligned sequences taking into account both thermodynamic stability and sequence covariation. In this contribution, we provide a tutorial on how to install and use RNAalifold, as well as a guide on how to interpret the results. less

The function of many noncoding RNAs (ncRNAs) depend on a defined secondary structure. RNAz detects evolutionarily conserved and thermodynamically stable RNA secondary structures in multiple sequence alignments and, thus, efficiently filters for candidate ncRNAs. In this chapter, we provide a step-by-step guide on how to use RNAz. Starting with basic concepts, we also cover advanced analysis techniques and, as an example for a large scale application, demonstrate a complete screen of the Saccharomyces cerevisiae genome. less
