While there is agreement on the drawbacks of centralized management, many approaches that address those do not scale well to large networks. We believe that effective management of future large-scale networks requires decentralized but coordinated control. In our recent work, we introduced the paradigm of pattern-based management, an approach that formalizes the use of graph traversal algorithm...

Crosscutting concerns are pervasive in embedded software, because of the various constraints imposed by the environment and the stringent QOS requirements on the system. This paper presents a framework for modularizing crosscutting concerns in embedded and distributed software, and automating their composition at the modeling level, for simulation and validation purposes. The proposed approach ...

Object-oriented software systems that are developed using aspect-oriented programming techniques consist of classes and aspects. Classes implement the primary functionality of an application, for example, managing stocks or calculating insurance rates. Aspects, on the other hand, capture technical concerns like persistence, failure handling, communication, or process synchronization. They are w...

Deployment has emerged as a major challenge in distributed real-time and embedded (DRE) systems. Application deployment planners must integrate numerous functional and non-functional constraints, such as security and performance, to produce correct deployment plans. The numerous deployment constraints and their complex interactions make manually deducing correct/efficient deployments hard. This...

AOP (aspect-oriented programming) is an important new software construction methodology because it allows to specify parts and behaviors of components in a view-based way, i.e. with aspects. While these aspects can be speciied independently from each other, a weaver tool combines them to the nal form of the component. This yields software that is better readable (since speciications are modular...

~.~chine translation has a scme%~at checquered history. There were already proposals for autcmatic translation systems in the 30's, but it was not until after the second world war that real enthusiasm led to heavy funding and unrealistic expectations. Traditionally, the start of intensive work on machine translation is taken as being a memorand~n of Warren Weaver, then Director of the Natural S...

Making a distributed system adaptable to the dynamic variations in the user requirements is a big challenge in software industries. It is identified that the solution for the adaptability of such dynamic variations can be achieved through reflective middleware. In this paper an efficient solution is proposed by combining aspect oriented approach with reflective middleware. The significant featu...

INTRODUCTION Many tracts of native vegetation still remain in the western portion of that vast North American grassland known as True Prairie. Some are mowed annually for the crop of excellent forage, but far greater areas are now in native pasture (Weaver & Fitzpatrick 1932, 1934). One result of the long years of study of the grazed portion of this grassland was the recognition of the manner i...

We report a case of Japanese girl with a rare disorder of Weaver syndrome, which was characterized by overgrowth with advanced and disharmonic bone age, craniofacial abnormalities, developmental delay, metaphyseal flaring of the long bones and camptodactyly. The patient was delivered at 38 weeks of gestation with a length of 54.2 cm (+ 2.6 SD), a weight of 3805 g (+ 2.5 SD) and an occipitofront...

Machine translation began in 1947 with an influential memo by Warren Weaver. In that memo, Weaver noted that human code-breakers could transform ciphers into natural language (e.g., into Turkish)  without access to parallel ciphertext/plaintext data, and  without knowing the plaintext language’s syntax and semantics. Simple wordand letter-statistics seemed to be enough for the task. Weaver th...
