Following the recent trend in the development of the renewable energy market, complemented with the future and emerging technologies, the leading role of the grid connected converter is well established. In the future energy market, as an interconnecting element, it will serve to secure reliable power supply with extraordinary power quality characteristics. This paper will aim at presenting the basic...
In this paper, as binary modulation schemes, the differential on-off keying (DOOK) system, which can achieve anti-background noise capability and high data transmission efficiency, is considered. In order to solve the synchronization slip, a visible-light framed DOOK system embedding {-1,+1}-synchronization signal pattern is proposed. Moreover, theoretical formulas of detection and false alarm probability...
Networks-on-chip (NoCs) have become a new chip design paradigm as the size of transistors continues to shrink. Globally-asynchronous locally-synchronous (GALS) on-chip networks are proposed for solving issues such as large clock tree distribution and signal delay variations. More interestingly, for the GALS networks using m-of-n delay-insensitive interconnect, the asynchronous interconnect not only...
Low power wide area network (LPWAN) receivers must first decide about the presence of a transmission in order to retrieve the information that was being sent by wireless sensor nodes. This is exacerbated by the use of modern coding techniques that are able operate at very low signal to noise ratio (SNR), and inaccuracies originating from the transmitter hardware. Several, mostly low complexity methods...
Many dynamic hybrid race detectors aim at detecting violations of the lockset discipline in execution traces of multithreaded programs. They are designed to abstract memory accesses appearing in traces as contexts. Nonetheless, they keep these contexts in different extents and partition the sets of contexts into equivalent classes of different granularity. In our case study, we compare three detectors...
Exploitation of the statistical properties of classical or non-classical light sources is the cause of fascinating new applications. For the two last decades, ghost imaging has emerged as a way to form images of an object with a Single Point Detector (SPD) that does not have spatial resolution [1-5]. By taking into account space-time duality in optics, the extension of the results of spatial ghost...
The paper presents the design and optimisation of memory buffer in the SALT (Silicon ASIC for LHCb Tracking) ASIC. The SALT is a new 128-channel readout ASIC for silicon strip detectors in the Large Hadron Collider beauty (LHCb) experiment at the Large Hadron Collider (LHC) in CERN. The stochastic nature of phenomena detected by the ASIC results in a very different amount of data after each collision...
Recently, researchers found a new type of attacks, called time synchronization attack (TS attack), in cyber-physical systems. Instead of modifying the measurements from the system, this attack only changes the time stamps of the measurements. Studies show that these attacks are realistic and practical. However, existing detection techniques, e.g. bad data detection (BDD) and machine learning methods,...
For compact integration of 13.56MHz NFC functionality in mobile devices, a small planar loop antenna is a necessity. Active load modulation (ALM) is a commonly adopted technique to boost load modulation amplitude to overcome weak inductive coupling in small antennas. However, due to the challenges of phase synchronization, ALM is mainly limited to low data rate NFC applications. This paper describes...
In this paper, a novel pilot-aided algorithm is proposed for the detection of integer frequency offset (IFO) in orthogonal frequency division multiplexing (OFDM) systems. By transforming the IFO into two new integer parameters, the proposed method can largely reduce the number of trial values for the true IFO. The two new integer parameters are detected using two different pilot sequences, a periodic...
Molecular communication requires low-complexity symbol detection algorithms to deal with the many sources of uncertainty that are inherent in these channels. This paper proposes two variants of a high-performance asynchronous peak detection algorithm for a receiver that makes independent observations. The first variant has low complexity and measures the largest observation within a sampling interval...
This paper presents a patient-specific seizure onset detector based on the fusion of classification decisions from a common spatial pattern (CSP)-enhanced energy based detector and a neural synchronization based detector. Specifically, one level of the detector evaluates the amount of neural synchrony present within the electroencephalography (EEG) channels by calculating the condition number (CN)...
People with respiratory failure can be submitted to automatic synchronized transcutaneous functional electrical stimulation (TFES) with the person's respiration activity to improve respiratory function and airway clearing. Automatic detection of respiratory patterns for synchronizing TFES is a difficult task because different events such as cough and speaking can happen during stimuli application...
The FSM-SADF model of computation is especially suitable for analysing real-time applications with input-dependent behaviour such as different modes, variable execution times and scalable parallelism. Although FSM-SADF specifies which scenario transitions are possible, it does not specify how and when they are decided at runtime. Multiple actors of a scenario, e.g. video stream header parsing, may...
The method of structures creation of digital redundant devices with use of majority elements for fail safety support is considered in this report. This method is used for real-time systems. It is characterized by the fact that the redundant device is built in the form of excess structure with the loaded reserve, and its recovering organs are implemented on the basis of majority elements. The Important...
At the current state in multiuser detection, MMSE detector is very popular because it exhibits a good balance between performance and complexity. Therefore, we investigate the capacity-aware version of the MMSE scheme, linear detection method. In this paper, an novel MMSE MIMO detector is proposed with respect to MMSE MIMO channel estimation. We will show how a two-step MMSE MIMO estimator can be...
This paper is about the collaborative use of a far-infrared spectrum human detector and a visible spectrum human detector; the idea is to make collaborate these two detectors of different nature to automatically adapt the human detection whatever the luminosity changes and whatever the infrared emission changes of the scene. Our collaborative approach of detection handles: 1) gradual luminosity changes...
As we know, Cognitive Radio comes to improve the underutilization problem of available radio spectrum by using one of its functional called spectrum sensing. In this paper, we compare two methods between Fixed Sample Size Test and Sequential Detection specifically for spectrum sensing using OFDM signals with Gaussian noise. The compared parameter in this simulation is OFDM Average Block (AVB) which...
We develop two resistant to noise secure communication schemes based on time-delayed feedback oscillators with switching of chaotic regimes. One of the proposed schemes exploits the identical synchronization between the transmitter and receiver while another system uses the regime of generalized synchronization. The proposed schemes are studied numerically and implemented in a physical experiment.
The Compressed Baryonic Matter (CBM) experiment is a part of the Facility for Antiproton and Ion Research (FAIR) at Darmstadt, Germany. The challenge in CBM experiment is to measure the particles generated in nuclear collisions with unprecedented precision and statistics. To capture the data from each collision a highly time synchronized fault tolerant self-triggered electronics is required for Data...
