Electric vehicles will be a new paradigm for vehicle manufacturers due to the abundance and low cost of electricity, which will transform the landscape of existing gasoline vehicles. In the predictable near future, with the large scale manufacturing and utilization of electric vehicles, a new system which hosts and charges the electrical vehicles will be highly in need. Stemming from this development, this paper proposes a Smart Parking System, which embeds charging facilities in the parking slots of shopping malls or residential area, and continuously updates the parking slot status and shopping information for end-user to access through a smart-phone application using a designated IPv6 address. Such a Smart Parking System will ease the trouble of locating a parking slot, facilitate car charging and payment, and proffer the necessary shopping information. In short, the proposed system aims to make travel easier and more enjoyable.

High sampling rate signal acquisition is challenging for wireless platform in terms of energy supply and transmission delay. Instead of performing compression at sensor node or having in-network processing for data been sampled at Nyquist rate, Compressive Sensing (CS) is applied to enable real time wireless sensor network with strict energy and processing constraints by significantly reducing the sensor data volume that needs to be transmitted over wireless channels. This is accomplished by random sampling at sensor nodes without extra processing and a mixture model based collaborative signal reconstruction in the fusion centre. This method increases signal reconstruction performance while reducing the volume of transmission data. Analysis of data from experiment and simulation are provided, and the performance are evaluated by implementing a prototype wireless platform.

Traffic grooming technique is one of the important candidates to save energy for networks. In order to minimize the energy consumption using Integer Linear Program (ILP) or Mixed Integer Linear Program (MILP), the assumption has to be made that all the connection requests are accepted in the IP over WDM network. However, a connection request may be blocked in a real network. In this paper, a bi-objective ILP is proposed for minimizing the energy consumption in a blocking IP over WDM network. It maximizes the throughput for a given network first, and then minimizes the energy consumption for the obtained maximized throughput. The simulation results show that the bi-objective method can save half of the energy consumed in the single-objective method if only the throughput is maximized.
流量疏导技术是网络节能的重要候选技术之一。为了使用整数线性规划(ILP)或混合整数线性规划(MILP)使能耗最小化,必须假设IP over WDM网络接受所有连接请求。但是,在真实网络中,连接请求可能会被阻塞。本文提出了一种双目标ILP算法,以使WDM网络上的阻塞IP的能量消耗最小。它首先最大化给定网络的吞吐量,然后最小化所获得的最大吞吐量的能耗。仿真结果表明,仅在吞吐量最大化的情况下,双目标方法可以节省单目标方法一半的能量。

For benefiting from incorporating the class information, partial least squares (PLS) and its two dimension version (2DPLS) have been widely employed in face recognition when extracting principal components. However, currently popular statistic methods, such as principal component analysis (PCA) and linear discriminant analysis (LDA), only learn holistic, not parts-based, representations which ignore available local features for face recognition. In this paper, we propose a novel approach to extract the facial features called two dimension nonnegative partial least squares (2DNPLS). Our approach can grab the local features via adding non-negativity constraint to the 2DPLS, and can also reserve the advantages of 2DPLS, which are both inherent structure and class information of images. For evaluating our approach's performance, a series of experiments were conducted on two famous face image databases include ORL and Yale face databases, which demonstrate that our proposed approach outperforms the compared state-of-art algorithms.

Amplify and forward is a classical basic user cooperation scheme. In this paper, we propose a Physical-network-coding-based amplify and forward scheme. In time slot 2, users transmit the combinations of the partner's message and their own message through pseudo physical-layer network coding. This is the greater different from the classical scheme, where the user only transmits the partner's bits in cooperation. An outage probability analysis showing the improved performance is carried out, and computer simulations results are shown to agree with the analytical results.

Accurate prediction of received signal strength is pivotal to reliable wireless communications. Unfortunately, wireless signals are often subject to random attenuation due to the environment around the receivers. One of the degradation factors that contributes to such loss is shadowing loss. It is well known that the shadowing losses of two nearby radio links are correlated. In this paper, we study the features of three existing models for correlated shadowing loss, namely autocorrelation model, cross-correlation model and joint path loss model, and establish the relationship between them.

Electrocardiogram (ECG) has been widely used in clinical diagnosis of cardiac arrhythmia. In particular, real-time detection of lethal cardiac arrhythmia such as ventricular tachycardia and ventricular fibrillation is important for patients with cardiovascular diseases. In addition, ST deviation during exercise indicates insufficient blood supply or infarction in myocardium, and autonomic imbalance implied from heart rate variability is associated with the mortality. However, physical activity (PA) usually confuses these interpretations. In this study, PA-related ECG analyses and real-time implementation on mobile devices will be addressed. Incorporating PA into ECG analysis not only avoids the confounding interpretation caused by PA, but also provides a way to probe cardiac functions during different PAs.

Logging-while-drilling (LWD) and measurement-while-drilling (MWD) applications have prompted the development of acoustic telemetry for retrieving downhole data. In this paper, a multilevel frequency shift keying (ML-FSK) modulation transceiver with pseudo-coherent differential energy detection is proposed and optimized for such acoustic telemetry applications. The motivation of employing the proposed multilevel FSK transceiver is its ability to cancel the effect of large drilling noise (drill bit noise and surface noise) with a low-complexity transceiver architecture, and its relative ease of dealing with oscillator or clock drifts caused by the harsh operating environment. To achieve better bit error rate (BER) over non-coherent demodulation while retaining the drilling noise cancellation capability, the receiver is modified to a pseudo-coherent demodulator. To further improve robustness, forward error correction (FEC) coding is applied and several coding options are evaluated over realistic acoustic drill string channel in the presence of drilling noise. The drill string channel investigated is made up of 110 segments, spans 1.011 km in length, has a characteristic comb-filter channel structure, with four pass bands (2nd, 3rd, 4th and 5th) used for telemetry.

It is known that iterative reweighted least squares (IRLS) algorithms are efficient techniques for the design of digital filters. The main computational load in IRLS algorithms is to solve a series of weighted least squares (WLS) subproblems, which usually needs the time-consuming evaluation of matrix inversion. This paper presents a new and very efficient IRLS algorithm, in which a simple iterative procedure is developed for solving those WLS subproblems. It is verified that the iterative procedure is guaranteed to converge and is computationally more efficient than using matrix inversion. Thus, the design efficiency is improved greatly, especially for high-order filters. Design examples and comparisons to some existing algorithms are given to show the excellent performance of the proposed algorithm.

The underwater acoustic (UA) channel is dispersive in both time and frequency with severe frequency-dependent signal attenuation. Efficient channel estimation and tracking are crucial to coherent high-rate UA communication. In this paper, we propose a new compressed sensing (CS) based channel estimation method with block-by-block channel tracking for UA communication. Compared with conventional channel estimation algorithms, the proposed method efficiently exploits the sparsity of the UA channel, and improves the channel tracking capability of UA communication system. The proposed algorithm was tested during our UA communication experiment conducted in December 2012 in the Indian Ocean off Rottnest Island, Western Australia. At a data rate of 8 kbps (QPSK constellations), average uncoded bit-error-rates (BERs) of 3% and 14% have been achieved over 1 km and 6 km ranges, respectively, using MMSE equalization based on the proposed channel estimation and tracking method.
