    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (239 KB)

    The authors compare the utilization of three multivariable stability margins for stability analysis of multivariable linear and nonlinear dynamical systems. The three margins considered are those developed by R.W. Bass (1956, 1983), J.C. Doyle (1982) and M.G. Safonov and are commonly represented by rho , mu , and K/sub m/, respectively. These margins provide the analyst with varying degrees of bot... View full abstract»

    Linear systems of automatic control with interconnected subsystems are considered. The behavior of each subsystem is characterized by a quadratic integral criterion. The problem of multicriteria optimization in such systems is formulated and solved. The solution is obtained on the basis of the principle of proportional damages, which ensures the following properties: the control of law is synthesi... View full abstract»

    The authors show that the synergetic combination of both surface- and edge-based segmentation processes can lead to more accurate segmentation results than just either one alone. A segmentation algorithm which integrates edge and surface information to come up with a high-level description of a scene given a range image is proposed. It is shown that the surface parameters can be used for accurate ... View full abstract»

    An attempt was made to develop a protocol, which will use both single packet and arbitrary-gated service schemes. in which the token-holding-time (THT) of a station depends on its buffer occupancy or queue length. If the buffer occupancy is less than a preassigned threshold value, the station will hold the token for only one packet service time. If the buffer occupancy is greater, then the THT wil...

    A node in a switch architecture is examined. The node receives messages, stores and processes them locally, and transmits them to other nodes. Both message transmission and processing times depend on the message length, which is a random variable. The node is modeled as a queue with a single server where the interarrival and service times are related, and different cases are studied where this rel... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (332 KB)

    Software testing cannot guarantee that a program is at least correct with respect to the inputs over which the program was tested. This is a problem when testing concurrent programs, or could also be due to the possibility of a mistake in evaluating the results of a test of a sequential program. It is shown that, even if such evaluation mistakes are eliminated, testing still cannot normally guaran... View full abstract»

    The synchronization in the code-division multiple-access (CDMA) fiber-optic networks reduces interchannel interference, permits larger number of stations, and gives higher throughput. In the star topology proposed, very strict synchronization of transmitters and equalization of propagation delays over various paths in the network is achieved since a single optical source is used for the whole netw...

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (332 KB)

    Agglomerative clustering is proposed as an unsupervised training method. The algorithm is controlled either by giving the number of clusters or by specifying some threshold value. In the latter case, the algorithm uses the adaptive threshold technique to achieve its natural clusterings. Similar to merging regions in image segmentation (M.D. Levine et al.. 1981), this method grows the clusters by a... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (256 KB)

    The authors consider the tilt error problem in a multisensor radar system using an arbitrary number of radars. Assuming that the sensors measurements are bias-free, or the bias has been removed, a measurement model of the tilt error is obtained by transforming each secondary sensor data to the primary sensor frame. Then an adaptive Kalman-filter-based technique is used to estimate the reference fr... View full abstract»
