Nhận thấy rằng, báo khoa học là một vấn đề rất cần thiết cho Việt Nam trong thời điểm hiện nay. Tuy nhiên, các báo khoa học thường phải tốn tiền mua, nhất là báo IEEE.

Electric ship drive and power system

Summary: Secretary of the Navy Richard Danzig announced on Jan. 6 that the Land Attack Destroyer (DD 21) will be the US Navy's first class of ships designed and built with electric drive featuring an integrated power architecture. In addition to supporting the needs of DD 21, this power system architecture was described as a future technology enabler for advanced energy sources and ship capabilities. The warfighting benefit of one such capability, rail guns, was recently evaluated by the CNO's Strategic Studies Group. This paper discusses aspects of the integration of such a capability into a future destroyer with an integrated power system.

Developing powerline carrier applications on embedded systems
Gabriel, C.; Horia, H.; Pop, O.A.

Summary: Powerline carrier (PLC) is a popular communication technique that uses the existing power wiring (120 V, 240 V, etc) to carry information. It is a kind of "wireless" means of communication, because technology can supersede the installation of dedicated wiring in some applications. Although the powerline environment is a hard environment for any communication (switch mode power supplies use high frequency components, and usually a lot of tonal noise is generated) and everything (attenuation, phase response and noise level) can change over the frequency range, the transmission can be performed with amplitude shift keying, frequency shift keying or phase shift keying (for inexpensive but limited performance devices) or based on spread spectrum with a correlator for better performance devices. The paper proposes a modem solution for integrating powerline carrier capabilities inside microcontroller embedded systems in order to increase the communication capabilities of such devices. Extending network abilities and including powerline carrier resources in embedded systems are the main benefits.

A position control differential drive wheeled mobile robot

Summary:For more accurate path tracking of a four-wheeled two-degrees-of-freedom mobile robot (WMR), a position control algorithm is proposed with two separated feedback loops, a velocity feedback loop and a position feedback loop. In the most conventional position control system of a WMR, internal error is mainly considered, while external error has, as yet, hardly been treated, although it plays an important role in accurate position control. This external error is caused by unexpected environmental situations. The proposed control algorithm is designed to compensate for both internal error and external error. This algorithm makes it possible to accurately follow the designed trajectory

Sensor integration for mobile robot position determination

Summary: The objective of the work presented is to determine an accurate position and orientation for mobile robots based on information received from multiple sensors. The approach taken in this paper is to integrate the information from odometry with the inertial system using Unscented Kalman Filter (UKF). The UKF is the newest extension of widely used estimation method, Kalman Filter. The UKF is more accurate and simpler than the extended Kalman filter applied to nonlinear systems.
