International Conference on Acoustics, Speech, and Signal Processing (ICASSP)

作者： H. Nii Heuristic Programming Project Computer Science Department University of Stanford USA

In the past fifteen years, artificial intelligence scientists have built several signal interpretation, or understanding, programs. These programs have combined "low" level signal processing algorithms with knowledge representation and reasoning techniques used in knowledge-based, or expert, systems. [4] They have shown how the use of task domain knowledge combined with symbolic manipulation techniques can be of use in making signal understanding systems more effective and efficient. HASP/SIAP is one such program that tries to interpret the meaning of passively collected sonar data. In this paper we explore some of the AI techniques that contribute in the "understanding" process. We also describe the organization of HASP/SIAP system as an example of a programming framework that show promise for applications in a class of similar problems.

Weakest specifunctions for BSP

引用

Parallel Processing Letters 2001年第4期11卷 439-454页

作者： Chen, Yifeng Sanders, J.W. Department of Maths and Computer Science University of Leicester University Road Leicester LE1 7RH United Kingdom Programming Research Group Oxford University Computing Laboratory Parks Road Oxford OX1 3QD United Kingdom

This paper introduces a calculus of weakest specification for supporting reuse of established components in deriving a design (in the sense of formal methods). The weakest specifunction generalizes the notions of weakest pre-specification and weakest parallel environment;but instead of calculating the weakest required component of a target specification, it calculates the weakest specification function whose value refines the target when applied to an established component. In particular it overcomes the restriction of those other calculi to taking merely one required component at a time. The theory of specifunctions is applied to a new weakest-design calculus in the context of BSP. The calculus is based on the par-seq specifunction which involves two required components: it places one established component in parallel with one required component and the result in sequence with another required component to meet a given specification. A calculus is provided for the par-seq specifunction and it is applied to the derivation of a distributed BSP algorithm for greatest common divisor.

The report considers the peculiarities of the distribution of computing resources in cloud systems. The most used classification of existing technologies of cloud services is considered. The advantages and disadvantages of such technologies are analyzed. The characteristic features of cloud computing that will need to be taken into account when allocating resources have been identified. IAAS technology has been shown to be most vulnerable to suboptimal resource allocation or reallocation. An expanded set of indicators for IAAS technology has been identified, including time-varying ones that need to be considered in resource allocation. Solving this problem will increase the efficiency of the use of cloud computing resources in general, increase application productivity and reduce the cost of infrastructure and its maintenance. © 2022 IEEE.

3rd International Workshop on Equation-Based Object-Oriented Modeling Languages and Tools, EOOLT 2010 - In Conjunction with the MODELS 2010 Conference

ModelicaML is a UML profile for the creation of executable models. ModelicaML supports the Model-Based Systems Engineering (MBSE) paradigm and combines the power of the OMG UML standardized graphical notation for systems and software modeling, and the simulation power of Modelica. This addresses the increasing need for precise integrated modeling of products containing both software and hardware. This paper focuses on the implementation of executable UML state machines in ModelicaML and demonstrates that using Modelica as an action language enables the integrated modeling and simulation of continuous-time and reactive or event-based system dynamics. More specifically, this paper highlights issues that are identified in the UML specification and that are experienced with typical executable implementations of UML state machines. The issues identified are resolved and rationales for design decisions taken are discussed.

An alternative to Quiescence: Tranquility

An alternative to Quiescence: Tranquility

International Conference on Software Maintenance (ICSM)

作者： Yves Vandewoude Peter Ebraert Yolande Berbers Theo D'Hondt Department of Computer Science Leuven Belgium Programming Technology Laboratory Brussels Belgium

This paper revisits a problem that was identified by Kramer and Magee: placing a system in a consistent state before and after runtime changes (1990). We show that their notion of quiescence as a necessary and sufficient condition for safe runtime changes is too strict and violates the black-box design principle. We introduce a weaker condition, tranquility; easier to obtain, less disruptive for the system and still sufficient to ensure application consistency. We also present an implementation of this concept in a component middleware platform

Dual-image based reversible data hiding scheme using pixel value difference expansion

引用

International Journal of Network Security 2016年第4期18卷 633-643页

作者： Jana, Biswapati Giri, Debasis Mondal, Shyamal Kumar Department of Computer Science Vidyasagar University Midnapore721102 India Department of Computer Science and Engineering Haldia Institute of Technol India Department of Applied Mathematics with Oceanology and Computer Programming Vidyasagar University India

In this paper, we propose a dual-image based reversible data hiding scheme. Here, we divide a secret message into sub-stream of size n bits, where n-1 bits are embedded using Pixel Value Differencing (PVD) and 1 bit is embedded using Difference Expansion (DE). We consider two consecutive pixels from cover image, calculate the difference between them andthen embed n-1 bits secret message by modifying the pixel pair. Again, we consider that modified pixel pair to embed 1 bit secret message using embedding function. After that, we distribute these two stego pixel pairs among dual image depending on a shared secret key bit stream. At the receiver end, we extract the secret message successfully and recover original cover image from dual stego image without any distortion. Finally, we compare our scheme with other state-of-the-art methods and obtain reasonably better performance in terms of data embedding capacity.

SPar: A DSL for High-Level and Productive Stream Parallelism

SPar: A DSL for High-Level and Productive Stream Parallelism

This paper introduces SPar, an internal C++ Domain-Specific Language (DSL) that supports the development of classic stream parallel applications. The DSL uses standard C++ attributes to introduce annotations tagging the notable components of stream parallel applications: stream sources and stream processing stages. A set of tools process SPar code (C++ annotated code using the SPar attributes) to generate FastFlow C++ code that exploits the stream parallelism denoted by SPar annotations while targeting shared memory multi-core architectures. We outline the main SPar features along with the main implementation techniques and tools. Also, we show the results of experiments assessing the feasibility of the entire approach as well as SPar's performance and expressiveness. © 2017 World Scientific Publishing Company.
