This paper describes the software of a terrain scanning robot capable of autonomously manipulating a typical handheld detector for remote sensing of buried landmines in a manner similar to a human operator. The autonomous manipulation of the detector on unknown terrain requires an online terrain map to generate an obstacle free path for the end effector of the robot. The software includes a two...

is one approach which uses a separate feedkjack within the adaptive controller to cancel-the effect of the undesired feedback [6]. This scheme, however, requires special care in the implementation to avoid the cancellation of the reference signal all together (see [4] for details). Looking at feedback neutralization from a different point of view, it is clear that this algorithm generates poles...

It is known that both the number of Dyck paths with 2n steps and k peaks, and the number of Dyck paths with 2n steps and k steps at odd height, follow the Narayana distribution. In this paper we present a bijection which explicitly illustrates this equinumeracy. Moreover, we extend this bijection to bilateral Dyck paths. The restriction to Dyck paths preserves the number of contacts.

This paper proposes an improved performance cross-updating active noise system with online secondarypath modeling. The existing cross-updating active noise control system comprises three adaptive filters; a noise-control filter, a secondary-path modeling filter, and an adaptive-noisecancelation filter; where FxLMS algorithm is used in adaptation of the noise-control filter. In the proposed meth...

Connection tracking subsystem on Linux tracks states of network flows. It is utilized by packet filter for stateful filtering. In this paper, we propose solutions to issues that arise where connection tracking subsystem handles Routing Header and Mobile IPv6. We also describe how the current connection tracking subsystem handles IPv6 fragments without disturbing Path MTU discovery. As a result ...

This paper presents a combined active noise control and noise reduction scheme for hearing aids to tackle secondary path effects and effects of signal leakage through the fitting. While such leakage contributions and the secondary accoustic path from the reciever to the tympanic membrane are usually not taken into account in standard noise reduction systems, they appear to have a non-negligible...

We consider the problem of designing the trajectory of a radar mounted on a moving platform. We develop an adaptive algorithm that, at each time step, optimally selects the radar path in response to the estimated and predicted target parameters to improve the tracking accuracy. We derive our approach under a framework of sequential Bayesian filtering. We apply a sequential Monte Carlo method (p...

The paper presents an observer design for a class of hyperbolic PDE–ODE cascade systemswith a boundary measurement. The cascade systems consist of coupled PDEs, featuring one rightward and one leftward convecting first-order transport PDEs, and a set of ODEs, which enter the PDEs through the left boundary of the systems. The design, which is based on the Volterra integral transformation, relies...

In this paper, we investigate the maximally parallel attribute of P Systems. Some properties of P Systems are abstracted, which are the filter property and the enumeration property. They are applied to solve the sorting problem and the Hamilton cycle problem, respectively.

This paper first gave a brief introduction of communication channel models, and then describes the characteristics of the channel emulator. According to the characteristics of the channel model, multipath is a difficult problem for hardware implementation. In order to simplify the hardware, the polyphase filter can be used for multi-path delay. Then the paper reviews the polyphase filter in the...
