In iterative schemes of identification and control one of the particular and important choices to make is the choice for a model uncertainty structure, capturing the uncertainty concerning the estimated plant model. This is typically done in some normbounded form, in order to guarantee robust stability and/or robust performance when redesigning the controller. Structures that are used in the re...

Critical gap is the most important parameter associated with gap acceptance study especially in case of delay and capacity estimation. Many studies are reported on gap acceptance behavior of pedestrian but most of them confined to developed country where traffic is homogeneous and traffic rules are strictly followed. Uncontrolled intersections in case of developed countries control the traffic ...

This paper reports the results of a small study of requirements changes to the onboard software of three spacecraft subsequent to launch. Only those requirement changes that resulted from post-launch anomalies (i.e., during operations) were of interest here, since the goal was to better understand the relationship between critical anomalies during operations and how safety-critical requirements...

In 1998 Donovan and Howse proved that for all n there exist critical sets of order n and size s, where l rt J ~ s ~ n2;n with the exception of the case s = rt + 1 when n is even. In this paper we will present a construction for this case, where n :2: 6, based on the discovery of a critical set of size 17 for a Latin square of order 8. This verifies that there does exist a critical set of order ...

The focus of this paper is a participatory design process that is used as a means to enable multiple stakeholders' collaboration in discussing strategies, designs and solutions of a conceptual future factory. The reason for this study is the Swedish industrial sector's difficulty in attracting women and young people. The design process can adapt to various complexities, building on the creative...

In the heat-bath Glauber dynamics for the Ising model on the lattice, physicists believe that the spectral gap of the continuoustime chain exhibits the following behavior. For some critical inversetemperature βc, the inverse-gap is O(1) for β < βc, polynomial in the surface area for β = βc and exponential in it for β > βc. This has been proved for Z except at criticality. So far, the only under...

temporomandibular joint ankylosis causes limitation in mouth opening and establishes severe deformity and asymmetry in patient’s face, especially in children. surgery is the only treatment. this study was conducted to compare the effect of two surgical approaches, gap arthropasty and interpositional gap arthroplasty, on rate of maximum interincisal opening in temporomandibular joint ankylosis. ...
