The pole assignment method for non-delay multivariable systems has received a great deal of attention for designing feedback controllers to achieve desired objectives [1], [2]. Suh and Bien [3] have considered a root locus technique for linear systems with time-delay. Here is an attempt to present a pole assignment method for multi-input systems with input delay. The single-input system with de...

The robust stability analysis of asynchronous and uncertain sampled-data systems with constant incremental input delay is addressed in the looped-functional framework. These functionals have been shown to be suitable for the analysis of impulsive systems as they allow one to express discrete-time stability conditions in an affine way, enabling then the consideration of uncertain and time-varyin...

This work presents a new discrete-time adaptive-predictive control algorithm for a system with force disturbance and input delay. This scenario is representative of a mechatronic device for percutaneous intervention with pneumatic actuation and long supply lines which is controlled remotely in the presence of an unknown external force resulting from needle-tissue interaction or gravity. The ult...

This chapter discusses the positive effects of IT investment on firm financial performance when a distinct range of characteristics is examined. The relationship between IT investment and firm performance considering the information intensity of the industry is explored using a distributed lag model. Findings indicate both a positive effect and a positive lag effect of IT investment. The effect...

This research extends extant literature examining the relationship between IS use and performance. While prior theory has predominantly treated IS use as an antecedent of performance and hypothesized a positive effect of use on performance, this research provides an alternative perspective. Specifically, this paper theorizes that under certain contexts performance can be an antecedent of use an...

Shift work misaligns the environment and the body's internal clock. A new study suggests that this 'social jet lag' can be remedied by a 'personalized schedule', an intervention that may help reduce circadian misalignment and pathologies in shift workers.

In this paper, a neural-network-based control scheme is developed for the tracking control problem of a class of switched strict-feedback nonlinear systems with uncertain input delay and external time-varying disturbances. First, the auxiliary signals are obtained by masterly constructing a filter and a virtual observer. Then the adaptive backstepping technique and neural network (NN) are emplo...
