The square root (SR) Nyquist filter is always used as matched filter in digital systems to minimize the intersymbol interference (ISI), where the square root raised cosine filter (SRRC) is a popular choice. However, more filter choices substantially provide the engineer more flexibility in applications. Hence, this paper employs the SRRC, SR-Nyquist filter and low pass filter (LPF) as the matched...
Due to the technological development, the electronic power progress and economic stake, through the use of Wound Rotor Induction Motor (WRIM) has taken more and more places in different domains (transport, energy production, electric drive‥,) thanks to their robustness, efficiency and lower costs. Despite the performed work researches and the improvement that has been brought, these machines still...
The stability of the amorphous phase in phase- change-memory (PCM) devices can be affected by temperature-activated crystallization and resistance drift due to structural relaxation (SR). While amorphous chalcogenides are relatively stable with respect to crystallization, thanks to a high activation energy of about 2.5 eV, the lower activation energy of SR can result in a change of the electronic...
When packets are transmitted over braided-paths in visual sensor networks some intermediate nodes may relay most part of the traffic, turning part or the entire network inactive when they run out of energy. Due to the nature of visual monitoring, source nodes may have different relevancies for the application, according to the desired monitoring tasks and the current sensors' poses and fields of view...
This work presents a modification of traditional Oscillation-Based Test schemes for sampled-data systems. This new test scheme is based on doubling the sampling frequency when the oscillation changes its sign. This way, the DC level of the output oscillation signal becomes a simple signature sensitive to the settling errors in the device under test and to its oscillation features. The proposed technique...
In multi-slice magnetic resonance imaging (MRI) the resolution in the slice direction is usually reduced to allow faster acquisition times and to reduce the amount of noise in each 2-D slice. To address this issue a number of super resolution (SR) methods have been proposed to improve the resolution of 3D MRI volumes. These methods typically involve the use of prior models of the MRI data as regularization...
This paper presents how to add flexibility to reduce the overall power consumption in a CMOS operational amplifier by replacing few MOS transistors with floating gate MOSFET (FGMOS). The disadvantages of doing this are also discussed. The performance of the proposed circuit using unity gain bandwidth (GBW) and slew rate (SR) as figure of merit is presented. The Nested Miller compensation (NMC) is...
fcCuBE™ technology by STATSChipPAC has gained significant momentum due to several benefits it offers, namely; Bump Pitch (BP) reduction capability with Cu-column interconnect, cost reduction as a results of substrate design rule relaxation associated with Bond-On-Lead (BOL) and Open Solder Resist (SR) design, and advanced FAB node compatibility due to significant reduction of stress on Extreme low-K...
In this study, an on chip bus driver TEG (test element group) has been developed for the data transmission performance at TSVs for 3D IC integration. The on chip bus driver TEG consists of transceiver (TX), receiver (RX) and TSV group which has 2, 4 and 8 TSVs for the analysis of the TSV transmission performance with different load effects which are caused by different number (2, 4, and 8) of chip...
In this paper, a novel covariance spectrum sensing approach used in cognitive radio (CR) networks which is based on the dynamical stochastic resonance (SR) technique is proposed. When the optimal SR technique is introduced as the pre-processing method for the covariance-based detection and after it has been realized, it can increase the signal-to-noise ratio (SNR) of the primary user (PU) signal and...
Although the Portuguese electricity system liberalization process started almost 20 years ago, 83% of electricity generated in 2010 still benefited from a State guaranteed price, independent of market behavior. This applies not only to producers using renewable energy sources and cogeneration under feed-in tariffs, but also to all conventional power plants that undersigned a power purchase agreement...
The distribution of multimedia streaming requires efficient management strategies in multisite environment with multiple senders and receivers. The intermediate nodes between senders and receivers act as the Streaming Routers (SR1). They play an important role in the distribution of required contents by relaying and dropping video frames which depends on the network characteristics of peer receivers...
In this paper, we investigate a path selection approach for wireless cooperative multihop communications with one source, one destination, and multiple intermediate relaying nodes, which are clustered linearly. Specifically, we adopt a cooperative maximum ratio combining (C-MRC) technique as a framework for the path selection approach, namely a C-MRC-based approach and a modified C-MRC-based approach...
This paper presents a procedure to select roadway luminaire based on IES and CIE roadway classification. Luminaire performance indices such as utilization factor, efficiency and surrounding ratio are utilized for the selection procedure. The developed program compares these luminaire performance indices and selects the proper luminaire considering lighting criteria. The selected luminaire can be used...
Evolvable Hardware (EHW) is an approach to the creation of hardware circuits based on a goal-oriented evolutionary process inspired by natural evolution. This approach allows the exploration of a very large design search space, ideally enabling to find solutions that are better in terms of resource requirements, accuracy or timing performance, with respect to traditional design methods. To exploit...
A novel fast heuristic algorithm for operating reliability constrained unit commitment is proposed in this paper. The loss-of-load probability constraints are fulfilled by the iteration between the traditional spinning reserve constrained unit commitment and the operating reliability estimation. The features of the approach are the fastness of the algorithm and the robustness of the results. Even...
In this paper, an effort is made to enlarge a low resolution image. This paper presents an effective novel single image super resolution approach to recover a high resolution image from a single low resolution input image. The approach is based on an Iterative back projection (IBP) method combined with the Canny Edge Detection and error difference image to recover high frequency information. This...
It has been proven that performance of video coding at low bit rates can be improved by down-sampling a video before compression and then using super-resolution to up-sample it after decompression. Such techniques are especially important for limited bandwidth communications. In this paper we propose an adaptively down-sampling based coding (DBC) method which performs rate distortion (RD) optimization...
In this paper, we propose a novel technique for feature preserving interpolation of multi spectral (MS) images. Given an MS image and a panchromatic (PAN), high resolution MS image is obtained by estimating the details from the PAN image. We exploit the fact that the local geometry of the low resolution MS image is similar to that of the PAN image. The image features such as edges, corners, and curves...
Fault diagnosis is critical for improving product yield and reducing manufacturing cost. However, it is very challenging to identify the root cause of failures on a complex circuit board. Ambiguous diagnosis results lead to long debug times and even wrong repair actions, which significantly increases the repair cost. We propose an automatic diagnostic system using support vector machines (SVMs). The...
