in this study, the profitability of contrarian and momentum strategies were traded in mid- term based on trading volume. the stocks were categorized into three parts (high, middle and low) at the outset. then, the relationship between excess return with three components such as cross-sectional risk, lead-lag effect and time-series pattern were examined based on jegadeesh and titman approach.the...

This paper provides an overview of recent results for relay-delay systems. In a first section, simple examples illustrate the problems induced by delays in the synthesis of sliding mode controllers. Then, a brief overview of the existing results shows the present advances and limits in this domain. The last parts of the paper are devoted to new results: first, for systems with state delay, then...

If an observer sees a flashed (briefly presented) object that is aligned with a moving target, the perceived position of the flashed object usually lags the perceived position of the moving target. This has been referred to as the flash-lag effect, and the flash-lag effect has been suggested to reflect how an observer compensates for delays in perception that are due to neural processing times ...

in the present study, the effect of core on shear lag phenomenon in tubular structures is investigated. three different tubular structure models including model without core, model with central core and model with central core but eliminated in last 15 stories have been analyzed. a shear lag index is defined for evaluating these models. from examination of the results, the effective influence o...

Most capital projects have an implementation lag. We examine the effect of implementation lag on a levered firm’s investment decision. The main finding is that implementation lag can potentially have a substantial effect on a levered company’s investment trigger, and this effect can be significantly different from that of an unlevered company. The exact relationship between lag and investment t...

In a recent paper we presented the first adaptive control design for an ODE system with a possibly large actuator delay of unknown length. We achieved global stability under full state feedback. In this paper we generalize the design to the situation where, besides the unknown delay value, the ODE also has unknown parameters, and where trajectory tracking (rather than equilibrium regulation) is...
