With the increasing complexity of todays’ parallel computer systems and the design time being exponential in the number of system parts used, parallel design automation has become a necessity, rather than a luxury. The system parts are modeled using objectoriented technologies such that not only are the static features of the components encapsulated, but also are the dynamic design states. A sy...

For a family of dynamical systems we define sensitive dependence on parameters in a way resembling Guckenheimer’s definition of sensitive dependence on initial conditions. While sensitive dependence on initial conditions tells us that if we know the initial condition only approximately then we cannot make deterministic predictions, sensitive dependence on parameters tells us that if we know the...

Few studies have examined dynamic interactions between IT change and organizational change during information system evolution (ISE). We propose a dynamic model of ISE which characterizes ISE related change in four dimensions: 1) planned, 2) improvised, 3) organizational, and 4) IT related. The modelgenerated inductively through theory-building case studies enables us narrate a more comprehensi...

Beyond the effects of temperature increase on local population trends and on species distribution shifts, how populations of a given species are affected by climate change along a species range is still unclear. We tested whether and how species responses to climate change are related to the populations locations within the species thermal range. We compared the average 20 year growth rates of ...

In the past few decades, the field of positive behavior support has emerged from its origins in applied behavior analysis. However, the difference between an appropriate literature base and statewide implementation by a state MR/DD agency cannot be overstated. The development process and model for statewide system change in positive behavior support being implemented by the South Carolina Depar...

Todays multimodal systems, which allow full-body (3D) gestures and speech as input modalities, are quite restricted to easily interpretable coverbal gestures with a prede ned shape and meaning. In this paper, we propose methods to abstract the concrete shape of gestures by using high-level features and to integrate them with coexpressive words using their phonological attributes. The applicatio...

the agricultural sector was affected by climate change more than every other sectors, because it is close to nature. in other words, the effects of climate change were been on the farmers’ livelihood. farmers need to entrepreneurial changes for adaptation to climate change in their livelihood. hence, investigation of farmers’ entrepreneurial behavior in response to climate change was the main p...

Brain-implanted devices are no longer a futuristic idea. Traditionally, therapies for most neurological disorders are adjusted based on changes in clinical symptoms and diagnostic measures observed over time. These therapies are commonly pharmacological or surgical, requiring continuous or irreversible treatment regimens that cannot respond rapidly to fluctuations of symptoms or isolated episod...
