Shareholder valuations are economically and statistically positively correlated with independent director power, gauged by a composite of social network power centrality measures. Powerful directors’ sudden deaths reduce shareholder value significantly; other do not, consistent powerful directors increasing firm valuations. Further tests associate more less value-destroying mergers acquisitions...

Many declarative query languages for object-oriented (oo) databases allow nested subqueries. This paper contains a complete classiication of oo nested queries and appropriate unnesting optimization strategies based on algebraic rewriting. We adapt some known relational techniques and introduce new ones that use and are concerned with features speciic to object-oriented queries. In particular, w...

in this study, eutrophication was investigated in lake ontario to identify the interactions among effective drivers. the complexity of such phenomenon was modeled using a system dynamics approach based on a consideration of constant and variable stoichiometric ratios. the system dynamics approach is a powerful tool for developing object-oriented models to simulate complex phenomena that involve...

This paper investigate the possibility and effectiveness of multi-mode vibration control of a plate through real-time FPGA (Field Programmable Gate Array) implementation. This type of embedded system offers true parallel and high throughput computation abilities. The control object is an aluminum panel, clamped to a Perspex box’s upper side. Two types of control laws are studied. The first belo...

Db4o is an already established OODBMS solution for Java and .NET, providing a powerful and easy-to-use solution for object persistence. It is therefore desirable to make it accessible to programmers that use Eiffel, a well-known, pure object-oriented programming language offering features like design by contract, multiple inheritance, genericity and agents. The effort that this paper describes ...

Fast runtime reconfigurable hardware enables system designers to swap hardware into and out of an FPGA much as the pages of virtual memory are swapped into and out of virtual memory. Java provides a powerful object-oriented language with constructs to support multiple threads. In this paper, we discuss a method for developing reconfigurable hardware object class libraries, a runtime environment...

The Parallel Object-Oriented Specification Language (POOSL) is an expressive modelling language for hardware/software systems [10]. It was originally defined in [7] as an object-oriented extension of process algebra CCS [6], supporting (conditional) synchronous message passing between (hierarchically structured) asynchronous concurrent processes. Meanwhile, POOSL has been extended with real-tim...

Dynamic adaptability of operating systems becomes more and more important, to be able to deal with new requirements, without the necessity of recompiling and rebooting the whole system. In the eld of software development the object-oriented paradigm has been widly accepted as powerful method to achieve adaptability. This paper presents a novel approach to achieve ne-grained, dynamic adaptabilit...
