In this paper we present a model for the Flicker noise in quasi-ballistic transistors based on our improved core transport model. The model is validated with DC and noise measurements for an InGaAs nanowire FET and a Carbon nano-tube FET. The noise model, along with the core is valid from drift-diffusive to quasi-ballistic regimes of operation.
Salient Object Detection (SOD) has received much attention from the research community due to its increasing applications in the areas such as object detection and recognition, image editing, image and video compression, video summarization and so on. Most of the SOD methods are proposed in literature presuming that the digital images in which salient objects is to be detected, are free from any kind...
This article, discusses the problem with the influence of offset voltages and their drives generated in the measuring system in the process of forming a digital equivalent to a pre-formed value. A method and a schematic solution are proposed to reduce the total offset voltages in a measuring line, based on the mixed signal technology. Its limitations have been defined in relation to transformation...
RF signal is ease to be interfered, which makes the signal of transmitting and receiving impure to impact on wireless communication. It is not to be ignored for interfering between transceiver signals in package of transceiver, thus, insulating enough must be taken. In addition, the mount of noise introduced through a main interference source being from contribution of digital signal continuously...
With the rapid development of the power grid and the increase of power demand, the voltage level of the substation is improving rapidly. The noise caused by the transformer becomes a serious problem because it affects the health of the surrounding residents. In this paper, the noise of 1000kV transformer in Shanxi is measured and analyzed. The results show that the transformer noise has low frequency...
Introducing dummy slots is often applied to reduce cogging torque in permanent magnet synchronous machines. Although this solution always helps for smooth operation, its influence on noise and vibration (NV) performance needs more focused analysis. This paper employs two surface-mounted machines to investigate the effect of dummy slots, one of which is a 10-pole/12-slot machine (M1) with few magnetic-field...
In this paper are presented the results obtained after of evaluating three techniques of blind detection of spectrum holes used in Cognitive Radio (CR). The techniques evaluated correspond to the general technique of detection of energy levels, the method LAD BASED and the technique based on forward methods. The operation of these techniques was tested in simulation scenarios of a telecommunications...
In this paper, we examine the design and application of a one-time pad encryption system for protecting data stored in the Cloud. Personalising security using a one-time pad generator at the client-end protects data from break-ins, side-channel attacks and backdoors in public encryption algorithms. The one-time pad binary sequences from modified analogue chaos oscillators initiated by noise encoded...
The term ‘steganography’ encapsulates the practice of secretly embedding data into digital mediums including video, image and audio files. Although steganography is often associated with nefarious activities, conceptually it asserts several characteristics that render it useful in contemporary security applications. Not just a mechanism for criminals to communicate secret information over a digital...
Light sources are being competitive in the current market. Several types of these products have been widely used in the last two decades. They play a major role on the low voltage network as they produce and inject undesired noise onto the transmission lines of the PLC channel. This noise can be of a serious and negative effect when using the power line communications system to control the automatic...
This paper presents the antenna G/T degradation incurred when communications systems use very inefficient receive antennas. This work is relevant when considering propagation predictions at HF (2–30 MHz), where it is commonly assumed that antennas are efficient/lossless and external noise dominates over internally generated noise at the receiver. Knowledge of the antenna G/T degradation enables correction...
This paper shows how Light Emitting Diode (LED) Tubes negatively influence the data rate throughput of an indoor broadband Power Line Communications (PLC) channel. This negative influence on the data rate is due to noise being generated by the lamps. Differential Mode measurements were done with two PLC modems communicating and then introducing LED lamps that add noise to the channel. Drops in data...
This article investigates the interaction of white noise and the systematic noise of a time quantization that occurs in a time-interval counter (TIC). By buildiing a theoretical model, do analysis and simulatiion, understanding of quantization effect and noise interaction is achieved.
In this paper, prototypes of SC-cut resonators with 5 MHz resonant frequency are presented. The resulting short-term stability of some resonators has been measured lower than 8·10−-14 in terms of Allan standard deviation. The results are compared according to the overtone behavior on different vibrating modes to find a correlation with the intrinsic noise of the resonators. The comparison of these...
Fiber Optic Gyroscope is an optical sensor that can determine the position of the angle of motion of an object. FOG works based on the Sagnac effect, which states that the phase shift between two opposite waves propagates in the interferometry of the rotating ring, and proportional to the angular velocity. Goodness performance indicator of measurement system, is having a small noise. Angle Random...
This paper investigates the influence of the signal to noise ratio (SNR) and the type of a noise on the performance of two adaptive novelty detection methods. The evaluated methods are Learning Entropy (LE) and Error and Learning Based Novelty Detection (ELBND). The methods are compared in empirical way in classification framework. A classification based only on the error of the adaptive model was...
Change detection in multitemporal hyperspectral images (HSI) can be regarded as a classification task, consisting of two steps: change feature extraction and identification. To extract clean change features from heavily corrupted spectral change vectors (SCV) of multitemporal HSI, this paper proposes a novel spectrally-spatially regularized low-rank and sparse decomposition model (LRSDSS). It exploits...
Data provided by synthetic aperture radar (SAR) of Sentinel satellite can be useful for many applications. However, as for any SAR image, speckle noise is present in acquired images. Speckle properties are important for different operations of SAR image processing as filtering, edge detection, segmentation, classification. Thus, we first carry out preliminary analysis of speckle statistics and show...
This paper is to study the stabilizability and stabilization issues of linear dynamical systems based on the delayed and noisy feedback control.
