In this paper we study the disturbance response of open-loop neutrally stable linear systems with saturating linear feedback controller. It is shown that the closed-loop states remain bounded if the disturbances consists of those signals that do not have large sustained frequency components corresponding to the system’s eigenvalues on the imaginary axis (continuous-time) or on the unit circle (...

Temporary Shocks and Offshoring: The Role of External Economies and Firm Heterogeneity We construct a model of offshoring with externalities and firm heterogeneity. Due to the presence of externalities, temporary shocks like the Y2K problem can have permanent effects, i.e., they can permanently raise the extent of offshoring in an industry. Also, the initial advantage of a country as a potentia...

General Results about Integral Points on the Elliptic Curves y2 = x3 + mx2 (m+3)x + 1 References Let f(X) be a cubic polynomial defining a simplest cubic field in the sense of Shanks. We study integral points on elliptic curve...

Software testing research traditionally focuses on module testing rather than integration testing. Thus, many techniques are available to address module testing, but few are available for integration testing. Unfortunately, in practice, integration testing is often more important and more time consuming than module testing. For example, during the recent Department of Defense (DoD) Y2K testing ...

This report presents the work of AIS from January 1, 2000 to April 30, 2001. It summarizes the highlights during the author’s term as president. THE MERGER OF AIS AND ICIS Much of the focus of the officers of the AIS in the first half of 2000 was on the amalgamation of AIS and the International Conference on Information Systems (ICIS). ICIS is the premiere research conference in information sys...

The purpose of this study was to determine possible future disclosure practices related to information technology (IT) problems and the factors affecting such practices within an international accounting context. Disclosure practices related to Y2K disclosure practices was used as the central frame of reference for this study. Based on the survey of 1997/1998 fiscal-year annual reports from 161...

The Helmholtz equation arises when modeling wave propagation in the frequency domain. The equation is discretized as an indefinite linear system, which is difficult to solve at high wave numbers. In many applications, the solution of the Helmholtz equation is required for a point source. In this case, it is possible to reformulate the equation as two separate equations: one for the travel time ...

After the Y2K crisis many futurists feared that it might take another millennium to receive the same attention the year 2000 brought to us. Fortunately, we have seen that part of the interest in the future that the turning of century and millennium provoked seems to carry on. One of the most remarkable features of this continued appeal is regional foresight, or should I say regional planning? T...

1. INTRODUCTION At midnight on December 31 st last year one of the most widely anticipated events in computing took placeΧthe Millennium date rollover. Fortunately, the occasion was marked by virtually no disruption to computing services and the global meltdown that some authors had predicted did not arise. The purpose of this panel is to explore the experiences of and the lessons learned from ...

Despite of much work on TTS technologies and several TTS systems customized for Korean, current TTS systems output many errors in transliterating non-alphabetic symbols such as Arabic numerals and text symbols. This paper proposes TLAN (Transliteration Learner for Arabic-Numeral expressions) which can efficiently disambiguate the reading and meaning of Arabic Numeral Expressions (ANEs) in texts...
