In the modeling of continuous time systems, there is a need to convert the analog system to a discrete time system. The transform frequently encountered in the literature is the impulse invariant transform. This transform has proven to be inadequate for biological system modeling. In this paper we will review the available linear transforms and derive three new transforms, namely the centered s...

Hospitals are data-rich but information-poor. To develop a ‘continuous-learning health care system’ we need to harness our myriad information sources so that every patient encounter becomes the basis for new evidence of what works.

The author has chosen a somewhat inappropriate title for this paper; the file records he discusses are not "generalized," but rather tailored to predictable real world constraints, and the "management information systems" he considers form only a portion of the spectrum. Nevertheless, he presents an objective technique for file record design quite applicable in certain cases. Given 1) known and...

Industrial systems generate a lot of information for operators. Increased measurement information flow might cause difficulties for the process operators to observe the process states and faulty process operation. In this study, measurements and statistical variables are combined by fuzzy logic to generate key factors for several points in the continuous cooking digester. The overall diagnosis ...

In this paper, we describe a new graphical environment for learning continuous simulation. This open source software solution enables engineering students to learn and understand various real system models in the CSMP (Continuous Simulation Modelling Programme) language easily, and at the same time learn about the implementation aspects of simulation languages. The software provides efficient t...

For nearly every technology there is a doubling period over which the price/performance ratio of that technology improves by a factor of 2. Careful examination of longterm historical trends reveals that these doubling periods are themselves shortening every decade; implying that the rate of technical progress is hyperexponential. If we take the 1990s as the benchmark decade of technical progres...

ABSTRACT This paper presents two subspace-based methods, from the MOESP (MIMO output-error state space) family, for state-space identification of continuous-time fractional commensurate models from sampled input-output data. The methodology used in this paper involves a continuous-time fractional operator allowing to reformulate the problem so that the state-space matrices can be estimated with...

In this paper, we present a formal approach to modeling continuous system dynamics in SysML using differential algebraic equations (DAE’s). To support model-based design, the Object Management Group has recently developed the Systems Modeling Language (OMG SysMLTM). The language is well-suited for modeling many different aspects of largescale, multidisciplinary engineering projects. It allows s...

Continuous Queries (CQ) help users to retrieve results as soon as they become available. The CQ keeps track of two important events. If there is any change in the source information, it immediately notifies the user about that particular change. Secondly, it also keeps track of the timer-based events, in case information is required after a fixed period of time. Existing techniques such as Open...
