This paper focuses on the efficiency of the three-point interpolated discrete Fourier transform (IpDFT) method with maximum sidelobe decay windows on the normalized frequency estimation of a sine-wave corrupted by a stationary white noise. The efficiency is evaluated by means of the common uncertainty of the normalized frequency estimates, the expression of which is derived. Moreover, the efficien... View full abstract»

The paper describes an architecture for privacy-enhanced intrusion detection systems, that separates privacy-invasive and privacy-preserving operations. This can be useful in cases where less sensitive network monitoring is outsourced to a third party and more sensitive network monitoring operations and data forensics are performed in-house or by law enforcement agencies.

This paper describes our experience with concurrent asynchronous monitoring of large populations of end-user broadband-access routers. Despite of the wealth of research in large-scale monitoring, which assumes that it is possible to inquiry individual nodes efficiently, end-user access routers usually have manual legacy interfaces, either HTTP- or telnet-oriented. They seldom offer a direct interf... View full abstract»

The paper presents an Advanced Digital Signal Inspector (ADSI) used for acquisition and analysis of the internal digital of a System on Package (SoP) with a limited number of pins. The system is made of a commercial FPGA-board, connected to the module for data sampling and controlled by PC via USB; a suited graphical interface allows for configuration, multi trace real time data display and post p...

The neural network based method of individual conversion characteristic identification of multisensor using reduced number of its calibration/testing results is proposed in this paper. The proposed method is based on reconstruction of surface points of multisensor conversion characteristic by modular neural network. Each neural network module reconstructs separate point of the surface. The simulat... View full abstract»

Digital circuits complexity and density are increasing while, at the same time, more quality and reliability are required. These trends, together with high test costs, make the validation of VLSI circuits more and more difficult. Beside high-end ATE machines, strictly necessary in ASIC production phase, low-cost ATE test systems take place into market to implement a valid support in ASIC developme... View full abstract»

An intelligent multichannel data acquisition (DAQ) system based on the novel integrated circuit of universal sensors and transducers interface (USTI) or USTI-1M-20 with high metrological performances is described in the paper. It can be used with any existing quasi-digital as well as analog sensors and transducers. A parallelism in such systems was realized as time-division channeling and combined... View full abstract»

An increasing number of Electronic Control Units in passenger cars and high communication traffic have led the car manufacturers to splitting a single CAN network into several dedicated sub-networks running concurrently. Test and evaluation tools for CAN based networks are available for years, but they are mostly focused on test scenarios with up to two CAN networks, often based on the standard CA...

This paper addresses the problem of time period measurement of complex waveforms using the algorithms, which utilizes the associative memory network based weighted hamming distance (whd) technique and autocorrelation based techniques for noiseless and noisy waveforms. In this work, robustness of both the advance techniques, have been evaluated by simulated addition of random noise to a test comple... View full abstract»

The problem addressed in this work is the development of a technique for evaluating the energy consumption of ZIGBEE systems during normal operation. For this purpose, a simple ZIGBEE system consisting of a transmitter and a receiver is being measured with the help of an energy measuring scheme. The measurements are being held while these systems operate (either while communicating or while idle) ... View full abstract»

Lighting consumes one fourth of all energy consumed worldwide, and case studies have shown that commonly 50 to 90 percents of building lighting is unnecessary for the purposes required. Energy is wasted when light does not fall on its intended target, as when lighting fixtures allow light to go up instead of (as it is generally preferred) downward. Leakage also occurs when more light is generated ... View full abstract»

This paper addresses a crucial problem that exists frequently in data processing of biomedical signals. Almost all of these signals have a very low signal-to-noise ratio and a careful hardware and software development are essential to obtain a meaningful and accurate measurement. This is really important, especially when human diagnostics are at stage, since errors can affect patient's health and ... View full abstract»

The paper presents an experimental characterization of RFID technologies applied to process control in the marble industry. The final aim is the automatic detection of the presence of a marble slab under the abrasive or cutting heads inside an industrial machine. Four RFID systems at 125 kHz, 13.56 MHz, 868 MHz and 2.45 GHz have been implemented starting from commercially available tags and reader... View full abstract»

New approach to design inverted pendulum as a teaching aid is presented; it is based on the application of piezoelectric actuators that generate motion in one or two directions, depending on the number of degrees-of-freedom of inverted pendulum. High resolution and fast response time of piezoelectric drives make the control algorithms more effective than in case of using electrical motors. In the ... View full abstract»

Biomagnetic measurements such as magneto-cardiography (passive) or biosusceptometry (active) are promising to utilize at biomedical application. Comparison of different SQUID-magnetometers at unshielded environment are performed in order to optimization its designs. View full abstract»
