This paper deals with the robust output tracking problem of uncertain large-scale systems with input delay and the time-delay interconnections. Due to the informat ion transmission between subsystems, time delays are often encountered in large-scale systems and lead to the source of system instability. First, the original nonlinear time-delay systems can be represented by the Takagi-Sugeno fuzz...

The output stabilization problem for a linear system with an unknown bounded time-varying input delay is considered. The interval observation technique is applied in order to obtain guaranteed interval estimate of the system state. The procedure of the interval observer synthesis uses lower and upper estimates of the unknown delay and requires to solve a special Silvester’s equation. The interv...

In this paper the concept of multiple models and concept of switching controllers is used. The analog part of the system is described by finite set of continuous-time models with input delays. The continuous-time models include unmodeled dynamics in the form of affine matrix family. Using suitable transformation the models with input delay is converted in the delay free models. Then for multipl...

BACKGROUND For internal fixation of AO classification Type B lateral malleolar fracture, insertion of lag screws into the fracture plane and fixation with a one-third tubular plate as a neutralization plate are the standard treatment procedures. The one-third tubular plate is processed to a hook shape and hung on the distal end of the fibula. In this study, to compare the function of the hook a...

JEL Classification: F16, F43 This study examines the impacts of CO2 emissions on economic growth of Vietnam for the period 1986-2015 by using Autogressive Distributed Lag (ARDL) model. The results reveal that there is cointegration relationship between CO2 emissions and economic growth. In the long run carbon dioxide emissions have a significant negative impact on Vietnam economic growth. There...

This article proves a lemma which shows that two empirical processes will be uniformly close if they are evaluated with a small time lag. A new feature of our lemma is that we allow the empirical processes to be functionally weighted (by fi(t), see Lemma 2). A third lemma for functionally weighted empirical process is also included. AMS 1991 Subject Classification: Primary 62G10. Secondary 62P1...

Jet lag sleep disorder and shift work sleep disorder are the result of dyssynchrony between the internal clock and the external light-dark cycle, brought on by rapid travel across time zones or by working a nonstandard schedule. Symptoms can be minimized by optimizing the sleep environment, by strategic avoidance of and exposure to light, and also with drug and behavioral therapies.

This article examines whether domestic saving rate leads to higher domestic investment rate in the case of Malaysia. We argue that the results obtained from cross-sectional studies are not able to address this issue satisfactorily and highlight the importance of individual country case studies. Using the recently developed autoregressive distributed lag bounds testing procedure, the results rev...
