New realizations of Chua L-C and L-R mutators using current conveyors (CCII) and inverting current conveyors (CCII) are introduced. Two realizations are available in the literature using CCII for each of the types of L-C and L-R mutators. For the type 1a L-R mutator three new realizations using CCII and ICCII are introduced to complete a family of four realizations. For the type 1b L-R mutator ...

Introduction Recent studies of the Current Population Survey by Tucker and Kojetin (1997) and Dixon (2001) showed that unemployment rates were related to unit nonresponse in the CPS. Since households are in sample for 8 months in the CPS (over a 16-month period), there is an opportunity for households to leave or return to the sample. However, the number of “converts”, (households that agree to...

Recent educational software applications use Web technologies like XML to improve teaching methods in distance learning environments. Though XML has been already used to implement a high number of didactic resources, specification methodologies to develop these resources are rarely applied. As a consequence, the reuse and maintenance of those resources become a difficult task. This paper emphas...

The expert tracking algorithm Fixed-Share depends on a parameter α, called the switching rate. The switching rate can be learned online with regret 1 2 log T + O(1) bits. The current fastest method to achieve this is based on optimal discretisation of the Bernoulli distributions into O( √ T ) bins and runs in O(T √ T ) time. However, the exact locations of these bins have to be determined algor...

The software of the LEP beam orbit measurement system [1] allows the acquisition of the beam position for over 1000 consecutive turns. The acquisition can be synchronized to a deflection by a kicker in order to observe coherent betatron oscillations. In this paper we describe the use of this technique to study the dependence of head-tail damping on beam parameters and the tune dependence on the...

The current work presents the numerical prediction method to determine small-scale propeller performance. The study is implemented using the commercially available computational fluid dynamics (CFD) solver, FLUENT. Numerical results are compared with the available experimental data for an advanced precision composites (APC) Slow Flyer propeller blade to determine the discrepancy of the thrust c...
