A Middleware Framework for Constraint-Based Deployment and Autonomic Management of Distributed Applications

We propose a middleware framework for deployment and subsequent autonomic management of component-based distributed applications. An initial deployment goal is specified using a declarative constraint language, expressing constraints over aspects such as component-host mappings and component interconnection topology. A constraint solver is used to find a configuration that satisfies the goal, and the configuration is deployed automatically. The deployed application is instrumented to allow subsequent autonomic management. If, during execution, the manager detects that the original goal is no longer being met, the satisfy/deploy process can be repeated automatically in order to generate a revised deployment that does meet the goal.Comment: Submitted to Middleware 0

Materials and techniques of Art Nouveau architecture in Italy and Portugal: a first insight for an European route to consistent restoration

The results of the investigations on building materials and techniques of Casa Major Pessoa, a typical Art Nouveau construction in Aveiro (Portugal), and two coeval Art Nouveau buildings in Bologna (Italy) are presented as a methodological contribution to the restoration of this kind of buildings. This is the first step to ascertain the existence of a common thread between local materials, technologies and architecture in European countries at the same period. A holistic approach was adopted: materials were investigated along with architectural, structural and technological features, in order to achieve a first insight into the Art Nouveau architecture in Europe in particular for its consistent restoration without loss of historical memory

A Functional Architecture Approach to Neural Systems

The technology for the design of systems to perform extremely complex combinations of real-time functionality has developed over a long period. This technology is based on the use of a hardware architecture with a physical separation into memory and processing, and a software architecture which divides functionality into a disciplined hierarchy of software components which exchange unambiguous information. This technology experiences difficulty in design of systems to perform parallel processing, and extreme difficulty in design of systems which can heuristically change their own functionality. These limitations derive from the approach to information exchange between functional components. A design approach in which functional components can exchange ambiguous information leads to systems with the recommendation architecture which are less subject to these limitations. Biological brains have been constrained by natural pressures to adopt functional architectures with this different information exchange approach. Neural networks have not made a complete shift to use of ambiguous information, and do not address adequate management of context for ambiguous information exchange between modules. As a result such networks cannot be scaled to complex functionality. Simulations of systems with the recommendation architecture demonstrate the capability to heuristically organize to perform complex functionality

Demolition by Neglect: Repairing Buildings by Repairing Legislation

One of the biggest problems today facing communities with historic preservation ordinances is delinquent owners who don’t have the will or the finances to maintain their historic properties and landmarks. Historic preservation law plays an important role in building a sense of patriotism and community togetherness, fostering education and providing incentives for aesthetically pleasing architecture. When residents can identify with a community, this creates a dialogue and sense of belonging. There are also environmental and psychological impacts of preserving old buildings, since human beings are positively affected by their surroundings when they feel a sense of place. When buildings in a historic district fall prey to \u27demolition by neglect,\u27 meaning that the owners allow their property to reach a state of deterioration, the entire sense of community can be lost

The First World Trade Center Project: A Historical Tribute to a Great Mega Project

The tragic collapse of the World Trade Center on September 11, 2001 could not erase the memory of one of the most successful projects in history. The project set standards of excellence in project management for years to come. Using a retrospective look at the construction management of the WTC during the 1960s and 1970s, we show how the vision of great leadership and a determined organization transformed the economy of one of the most important cities in the world

Who paints the house? Scotswomen as housepainters and decorators from 1820

In the early 21st century it is still considered unusual to find a woman in paid employment as a skilled housepainter and decorator. Tradeswomen, in these most domestic of building trades, were working throughout Scotland during the 19th and 20th centuries. The women were those whose work self-identities were sufficiently strong to be recorded in directories and census returns. These are women who worked, not middle class or amateur women interior decorators dabbling in the arts and crafts because it was fashionable. The historical record is compared with contemporary records of women taking paid employment in these fields and also with the strong market created in modern times by the many TV DIY programmes encouraging women into DIY. The high level of present and past involvement of women in house-painting and decorating shows that the aptitude and ability exists at both the professional and amateur levels. The factual reality is compared with perception and prejudice within the industry and the barriers that were and are placed in front of women wishing to do this work

Ten virtues of structured graphs

This paper extends the invited talk by the first author about the virtues of structured graphs. The motivation behind the talk and this paper relies on our experience on the development of ADR, a formal approach for the design of styleconformant, reconfigurable software systems. ADR is based on hierarchical graphs with interfaces and it has been conceived in the attempt of reconciling software architectures and process calculi by means of graphical methods. We have tried to write an ADR agnostic paper where we raise some drawbacks of flat, unstructured graphs for the design and analysis of software systems and we argue that hierarchical, structured graphs can alleviate such drawbacks
