Traditional centralized management solutions do not scale to present-day large-scale computer/communication networks. They suffer from certain other drawbacks too: a single point of failure and hence lack of fault tolerance, and heavy communication costs associated with the central manager. It has been recognized that the decentralization/distributed solutions can solve some of the problems associated with centralized solutions. A new theoretical multi-level paradigm called ML-ADSD (Thulasraman et al. (2003)) assumes that all nodes in the same cluster are symmetric for multi-level adaptive distributed diagnosis algorithms for fully connected networks which is not true and cannot be realized in real life. In this paper, we propose a new algorithm called asymmetric multi-level adaptive distributed diagnosis algorithms, AML-ADSD. In this new algorithm, node parameters are to be classified using a standard benchmark program. Then, each node's performance can be calculated.

Parameter estimation of an autoregressive movmg average (ARMA) model is discussed in this paper by using bounding approach. Bounds on the model structure error are assumed unknown, or known but conservative. To reduce this conservatism, a point-parametric model concept is proposed, where there exist a set of model parameters and structure error corresponding to each input. Feasible parameter sets are defined for point-parametric model. Bounded values on the model parameters and structure error can then be computed jointly by tightening the feasible set using observations under deliberately designed input excitations. Finally, a constantly bounded parameter model is established, which can be used for robust control.

In this paper, we develop a 4-DOF force display system for the analysis by synthesis of facial color for the interaction with anthropomorphic agent. By using the system, we analyze the changes in facial skin temperature and facial color associated with circulation dynamics in response to forced actions. On the basis of the analysis, we propose a synthetic method for the affect display of virtual face with facial color and expression in force display, and the effectiveness of the method is confirmed. Finally, we develop a prototype of virtual arm wrestling system with anthropomorphic agent using synthesized dynamic three-dimensional facial color and expression.

Authors compared courses related to biomedical measurements at Wroclaw University of technology, where they are a base of speciality education and at Rzeszów University of technology, where they are merely a supplement on measurements of living organism for students of Metrology. This comparison revealed that there is a "canon" of the necessary and common knowledge offered to students.
Since the time. that electric power meters were introduced in the 1870s, the basic function of the meters has remained more or less unchanged. Many developed countries are still using the same technology that has exis...

The paper discusses complexity of circuit realization through Haar wavelet series. By applying permutation of binary coordinates of indices of Haar functions, a lower complexity of circuit synthesis through higher number of zero Haar coefficients has been achieved. Experimental results confirm the minimization of the number of non-zero Haar coefficients and the savings range from 5.25% to 99.41% for all benchmark functions.

The current-voltage characteristics of superconducting Bi-2223 tapes are not as sharp as those of metallic superconductors. This feature, characterized by their low n values especially at high fields and at high temperatures, is partly influenced by the sausaging of the superconducting filaments. In order to improve the n values, therefore, the effect of filament sausaging on the transport property was investigated in this research. It was found that the distribution of the thickness of the filaments is of a Gaussian type. The real distribution of the critical current density (Jc) is obtained from the thickness distribution and the apparent distribution of pinning strength estimated using the flux creep-flow model. The estimated real distribution of Jc is slightly sharper than the apparent distribution of Jc. However, the improvement of the n-value is predicted not to be remarkable, even if the filament thickness can be made uniform.

Numerous studies have indicated that ATM available bit rate (ABR) service can provide low-delay, fairness, and high throughput, and can handle congestion effectively inside the ATM network. However, network congestion is not really eliminated but rather it is pushed out to the edge of the ATM network, packets from TCP sources competing for the available ATM bandwidth are buffered in the routers or switches at the network edges, causing severe congestion, degraded throughput, and unfairness. This poor performance is mainly due to the uncoordinated interaction between the congestion control mechanism of TCP and ATM. It is well accepted that some form of cooperation at edge device would help to control TCP traffic flow over ATM more effectively. We have previously proposed the fair intelligent explicit window adaptation (FIEWA) scheme and fair intelligent ACK bucket control (FIABC) scheme. The key idea is to combine the feedback information from the receiver, from the underlying ATM network, and from the local information at the edge device intelligently to explicitly/implicitly control the TCP rate. We present a comparative simulation study on our schemes with other established schemes; to identify the characteristics of each different scheme; and to indicate the requirement for a fairer, simpler and more robust coherent approach at the edge device.

Applying the effective-mass approach, the energy eigenvalues of excitonic states in amorphous semiconductors are derived. It is shown that Wannier- Mott-type excitons can indeed be formed in amorphous solids. The results show that the occurrence of the double photoluminescence (PL) lifetime distribution peak, fast and slow, in hydrogenated amorphous silicon (a-Si : H) and hydrogenated amorphous germanium (a-Ge : H) can unambiguously be assigned to radiative recombinations from singlet and triplet excitonic states respectively. The dependence of PL peaks on the temperature and generation rate in a-Si : H and a-Ge : H is also discussed. The approach is general and simple and can be applied to study the charge-carrier transport and PL properties in any amorphous solid. [ABSTRACT FROM AUTHOR]
