Statecharts: A Visual Formalism For Complex Systems
, 1987
"... We present a broad extension of the conventional formalism of state machines and state diagrams, that is relevant to the specification and design of complex discrete-event systems, such as multi-computer real-time systems, communication protocols and digital control units. Our diagrams, which we cal ..."

call statecharts, extend conventional state-transition diagrams with essentially three olements, dealing, respectively, with the notions of hierarchy, concurrency and communication. These transform the language of state diagrams into a highly structured' and economical description language
Coverage Problems in Wireless Ad-hoc Sensor Networks
- in IEEE INFOCOM
, 2001
"... Wireless ad-hoc sensor networks have recently emerged as a premier research topic. They have great longterm economic potential, ability to transform our lives, and pose many new system-building challenges. Sensor networks also pose a number of new conceptual and optimization problems. Some, such as ..."

"... A widespread belief seems to be emerging, at least in the popular press, that the U.S. economy is in the throes of a fundamental transformation, one which is wiping out the 1972–95 productivity slowdown, along with inflation, the budget deficit, and the business cycle. A typical recent comment, in a ..."

Beyond computation: Information technology, organizational transformation and business performance
- Journal of Economic Perspectives
, 2000
"... To understand the economic value of computers, one must broaden the traditional definition of both the technology and its effects. Case studies and firm-level econometric evidence suggest that: 1) organizational “investments ” have a large influence on the value of IT investments; and 2) the benefit ..."

Nonlinear Neural Networks: Principles, Mechanisms, and Architectures
, 1988
"... An historical discussion is provided of the intellectual trends that caused nineteenth century interdisciplinary studies of physics and psychobiology by leading scientists such as Helmholtz, Maxwell, and Mach to splinter into separate twentieth-century scientific movements. The nonlinear, nonstatio ..."

-Schuster models. A Liapunov functional method is described for proving global limit or oscillation theorems for nonlinear competitive systems when their decision schemes are globally consistent or inconsistent, respectively. The former case is illustrated by a model of a globally stable economic market

The Regional Dimension of Economic Growth in Ukraine
, 2015
"... Abstract Regional asymmetries in Ukraine take the form of deep spatial divisions and gaps. Moreover, their evolutionary route has been influenced by the especially high growth rates of the Ukrainian economy during the first half of the 2000s and the deep recession of 2009-crisis. This paper explore ..."

explores the level of regional inequalities in Ukraine, detects the growth determinants in regions and investigates the spatial development pattern. The analysis shows that the 2009-crisis led the country into a transformational recession and a remodelling of its regional growth pattern.

We analyse the unreduced, nonperturbative dynamics of an arbitrary many-body interac-tion process with the help of the generalised effective potential method and reveal the well-specified universal origin of change (emergence), time and evolution in an a priori conservative, time-independent system. ..."

We then consider the detailed structure of this uni-versal evolutionary process showing its step-wise, “punctuated ” character, now
