A robust state feedback design subject to placement of the closed loop eigenvalues in a prescribed region of unit circle is presented. Quantitative measures of robustness and disturbance rejection are investigated. A stochastic optimization algorithm is used to effect trade-off between the free design parameters and to accomplish all the design criteria. A numerical example is given to illustra...

the stacking mechanism of the 1h-4h proton transfer in 4-pyridone, 4-pyridinthione and p-aminopyridineare constructed. for quantitative description of this process by means of the quamtumchemicalmethod density functional theory (dft) the activation energy (

this research chiefly focused on the application of mitigation strategies and traditional form of feedback in writing development of the fifth semester university students majoring in tefl and english translation fields based on vygotsky’s sociocultural theory in general and the notion of “zone of proximal development” in particular. to that end, this study relied on a pre-posttest experimental...

This paper presents a theory of corn monsense understanding of the behavior of electronic circuits. It is based on the intuitive qualitative reasoning electrical engineers use when they analyze circuits. This intuitive reasoning provides a great deal of important information about the operation of the circuit, which although qualitative in nature, describes important quantitative aspects of cir...

This paper documents a very pervasive underconfidence bias in the area of sensory discrimination. In order to account for this phenomenon, a subjective distance theory of confidence in sensory discrimination is proposed. This theory, based on the law of comparative judgment and the assumption of confidence as an increasing function of the perceived distance between stimuli, predicts underconfid...

Social network applications (SNAs) can have a tremendous impact in raising awareness to important controversial topics such as religion or politics. Sharing and liking are powerful tools to make some of those topics emerge to a global scale, as already witnessed in the recent Tunisian and Egyptian revolutions. However, in several countries the simple act of liking an anti-government article or ...

To the Editor: Iyer et al. have presented an interesting study of the usefulness of a deliberate apprenticeship model in the pediatric emergency department for third year students.1 The deliberate apprenticeship model appeared from both the quantitative and qualitative results to show benefits of deliberate apprenticeship. However a closer examination of the methodology reveals potential proble...

In this paper we describe one critical research program within a complex, ongoing multi-year project (2010 to 2014 inclusive) with the overall goal to improve the learning outcomes for first year undergraduate commerce/business students within an Information Systems (IS) subject with very large enrolment. The single research program described in this paper is the analysis of student attitudes a...

The tools of lattice theory are applied to readdress the static state feedback linearization problem for discrete-time nonlinear control systems. Unlike the earlier results that are based on differential geometry, the new tools are also applicable for nonsmooth systems. In case of analytic systems, close connections are established between the new results and those based on differential one-for...

corrective feedback (cf) and its different types have long absorbed many scholars and practitioners. as ellis (2009) mentioned some experimental studies need to be carefully designed to discover the relative effectiveness of each of these cf techniques. the goal of this qualitative study was to discover whether the employment of different cf strategies could bring about an attitudinal shift. to...
