A novel method of image super resolution using sparse representation has been discussed in this paper. The main purpose is to acquire the super-resolved image from the down scaled and blurred images. With the small number of elements from a huge set of vectors, sparse signal model approximates signals and this large dataset is called a dictionary. For construction of high and low-resolution dictionaries from the condensed atoms extracted from the training image patches, the Orthogonal Matching Pursuit approach has been used. The blurred and down-scaled version of the image is super resolved using the above-mentioned dictionaries. The outcomes are compared both instinctively by the visual assessment of the resulting super-resolve images by means of the proposed scheme and the bi-cubic interpolation method, and by comparing the Peak Signal-to-Noise Ratio (PSNR) obtained by the two approaches. Both the comparison metrics, i.e. visual quality of acquired super resolved images and PSNR measures show that the proposed approach is superior to the existing state of the art Bi-Cubic interpolation.
本文讨论了一种利用稀疏表示实现图像超分辨率的新方法。其主要目的是从缩小的和模糊的图像中获得超分辨图像。稀疏信号模型从一个庞大的向量集合中提取少量的元素来逼近信号,这个庞大的数据集被称为字典。对于从训练图像patch中提取的凝聚原子构建高分辨率和低分辨率字典,采用了正交匹配追踪方法。使用上述字典,图像的模糊和缩小版本具有超分辨率。通过对所提出的方案和双三次插值方法产生的超分辨率图像的视觉评估,以及通过比较两种方法获得的峰值信噪比(PSNR),本能地对结果进行了比较。对比指标,即获得的超分辨图像的视觉质量和PSNR指标都表明,该方法优于现有的双三次插值方法。

With the increasing number of vehicles in the last decade, car parking in congested areas and cities has become a big challenge. To resolve this problem, researchers have proposed Smart Parking System (SPS) which integrate new techniques and approaches into the traditional parking system. A SPS merges traditional parking with Internet of Things (IoT), Wireless sensor network (WSN) and other hardware. All type of existing SPSs are efficient and increase the performance, however the installation cost is too high due to which the system is not used widely. In this paper, a Vehicular Ad-hoc Network (VANET) based routing algorithm for SPS is proposed called Updating Block Route Algorithm (UBRA). It works by detecting congestion and by calculating the average speed of the vehicles. The proposed UBRA updates the route with a congestion less route and has low installation cost. Furthermore, it offers minimization of parking area searching time, fuel consumption and carbon dioxide (CO2) emission. The results and show that proposed UBRA saves up to 23.6%, fuel consumption and 9% CO2 emission when compared with existing approach.
在过去的十年中,随着车辆数量的增加,在拥挤的地区和城市停车已经成为一个巨大的挑战。为了解决这一问题,研究人员提出了智能停车系统(SPS),它将新的技术和方法融入传统的停车系统中。SPS将传统停车与物联网(IoT)、无线传感器网络(WSN)和其他硬件相结合。现有的所有类型的SPSs都是高效的,提高了性能,但由于安装成本太高,系统没有得到广泛应用。本文提出了一种基于VANET的SPS路由算法——更新块路由算法(UBRA)。它通过检测拥堵和计算车辆的平均速度来工作。所提出的UBRA以较少拥塞的路由更新路由,并且具有较低的安装成本。此外,它还提供了停车区域搜索时间,燃油消耗和二氧化碳(CO2)排放的最小化。结果表明,与现有方法相比,该方法可节省23.6%的燃油消耗和9%的二氧化碳排放。

Motor current signature analysis (MCSA) is an important, reliable and non-invasive technique for monitoring rotation machines. Spectrum analysis is a common way to implement MCSA, which allows large faults such as severe mechanical imbalance to be extracted successfully, but is often ineffective in the detection of incipient faults such as supporting bearings from motor drive systems because of noise and nonlinear interferences. To improve the performance of MSCA, this paper exploits the use of Empirical Mode Decomposition (EMD) method as an advanced tool to process motor current signals for noise reduction and nonlinear signature enhancement. The nonlinear demodulation property of EMD is firstly reviewed in association with the motor current signal models with fault cases. Then EMD is applied to signals from different fault cases from a centrifuge pump system to verify its performances in extracting the fault signatures for separating different faults. In conjunction with the envelope spectrum of separated intrinsic mode function (IMF), it shows that the proposed EMD based approach produces a better result in diagnosing common pump faults: small defects on impeller and bearings, which cannot be separated based on spectrum analysis.
电机电流特征分析(MCSA)是一种重要的、可靠的、无创的旋转机械监测技术。频谱分析是实现MCSA的一种常用方法,它可以成功地提取出严重机械不平衡等大故障,但由于噪声和非线性干扰,在检测电机驱动系统的支承轴承等早期故障时往往无效。为了提高MSCA的性能,本文利用经验模态分解(EMD)方法作为一种先进的工具来处理电机电流信号,以降低噪声和增强非线性特征。首先结合故障情况下的电机电流信号模型,综述了EMD的非线性解调特性。然后将EMD应用于离心泵系统不同故障情况的信号中,验证其提取故障特征以分离不同故障的性能。结合分离固有模态函数(IMF)的包络谱,表明基于EMD的方法在诊断常见的泵故障(叶轮和轴承上的小缺陷)方面取得了更好的结果,这些缺陷是基于谱分析无法分离的。

Performance Evaluation of String Based Malware Detection Methods 基于字符串的恶意软件检测方法性能评估
Pub Date : 2018-09-01 DOI: 10.23919/IConAC.2018.8749096

Conventional signature-based malware detection techniques have been used for many years because of their high detection rates and low false positive rates. However, signature-based detection techniques are regarded as ineffective due to their inability to detect unseen, new, polymorphic and metamorphic malware. To affect the weaknesses of the signature-based detection techniques, researchers have turned into behavioural-based detection techniques whereby a malware behavioural is constructed by capturing malware API calls during execution. In this context, API call sequences matching techniques are widely used to compute malware similarities. However, API call sequences matching techniques require large processing resources which make the process slow due to computational complexity and therefore, cannot scale to large API call sequences. To mitigate its problem, Longest Common Substring and Longest Common Subsequence have been used in this paper for strings matching in order to detect malware and their variants. In this paper we evaluate these two algorithms in the context of malware detection rate and false alarm rate.
传统的基于签名的恶意软件检测技术由于其高检出率和低误报率已经被使用了很多年。然而,基于签名的检测技术被认为是无效的,因为它们无法检测到看不见的、新的、多态的和变形的恶意软件。为了弥补基于签名的检测技术的弱点,研究人员转向了基于行为的检测技术,通过在执行过程中捕获恶意软件API调用来构建恶意软件的行为。在这种情况下,API调用序列匹配技术被广泛用于计算恶意软件的相似性。然而,API调用序列匹配技术需要大量的处理资源,由于计算复杂性使得过程缓慢,因此无法扩展到大型API调用序列。为了解决这个问题,本文使用了最长公共子串和最长公共子序列来进行字符串匹配,以检测恶意软件及其变体。本文从恶意软件检测率和虚警率两个方面对这两种算法进行了评价。

The paper describes design and development of a new ‘Personal Mobility Pod’ using low cost systems proposed for use in urban areas. Recent studies have shown increased use of personal mobility, suggesting the scope for further research. Adding to Mobility-on-Demand and vehicle share, such mobility pods could bridge the gap in driverless vehicle research and possibly be a solution to road traffic and congestion in urban areas. The proposed platform is a combination of sensory fusion with feedback managed by a main controller. The navigation system considers offline mapping and localisation with user interface, illustrating waypoints through Google Maps. A Pure Pursuit technique is used to track the vehicle along the given path. The scooters robust, reliable, safe design allows operation in various terrains. The developed platform is moreover proposed as a suitable test platform for driverless vehicle sub-system for testing and experimentation. The reliability of the pod has been tested and validated in two stages: laboratory testing and field testing.

As key components in centrifugal pumps rolling bearings work to reduce friction and maintain the impeller rotor in correct alignment with stationary parts under the action of radial and transverse loads. Effective fault detection of bearings allows appropriate preventive action to be taken timely, where required, and enhances performance operation. To develop an easy implementation and yet effective method for detecting and diagnosing pump bearing faults, the focus of this study is on utilising airborne sound signals which can be acquired more remotely and at lower cost, compared with vibration based methods which needs high numbers of sensors for monitoring a pump system. However, acoustic signals are much noisy, and it is difficult to detect machine faults using conventional signal processing methods such as time domain features, where the results have a limited and weak fault signatures. Thus, a more advanced signal processing technique: the envelope spectrum is adopted to establish accurate diagnostic fault patterns. The evaluating results show that the proposed method is effective and accurate to enhance the amplitudes at bearing characteristic frequencies, allowing diagnostic information to be extracted reliably, which also makes the Root Mean Square (RMS) of the envelope signals give a full separation between faulty and healthy cases over a wide range of pump operation, outperforming the vibration signals.
滚动轴承作为离心泵的关键部件,在径向和横向载荷的作用下,起到减小摩擦和保持叶轮转子与静止部件正确对中的作用。轴承的有效故障检测允许在需要时及时采取适当的预防措施,并提高性能运行。为了开发一种易于实现且有效的方法来检测和诊断泵轴承故障,本研究的重点是利用机载声音信号,与需要大量传感器来监测泵系统的基于振动的方法相比,机载声音信号可以更远程、更低成本地获取。然而,声信号具有很大的噪声,使用传统的信号处理方法(如时域特征)难以检测机器故障,其结果具有有限且较弱的故障特征。因此,采用一种更先进的信号处理技术:包络谱来建立准确的诊断故障模式。评估结果表明,该方法有效、准确地增强了轴承特征频率处的幅值,可靠地提取了诊断信息,并使包络信号的均方根(RMS)在泵的大范围运行中完全区分了故障和健康情况,优于振动信号。

Several different modeling languages and notations are used in diverse engineering disciplines for modeling of system processes and for control and monitoring functions. This paper applies a recently proposed diagrammatic language called the Flowthing Machine (FM) model to modeling the process diagrams of a currently existing waste water treatment facility. The modeling includes depictions of components and operations of the project to achieve a holistic picture for engineers. The resultant schemata demonstrate the advantages of the proposed modeling technique in comparison with other types of modeling methodologies (e.g., UL and SysML) and its viability as a conceptual base for the management and control of engineering systems.

The high demand side cost of electric vehicles (EVs) affects the wide use of EVs in practice. In this paper, a mathematical model is built to investigate the cost of the demand side by controlling EVs charging and discharging status, so that the demand side cost can be minimised under given tariffs. The battery degradation cost, the driving probability and the vehicle-to-grid (V2G) rebates are considered in the model. The most economic charging and discharging strategy for each EV can be determined through global optimisation. Simulation studies demonstrate the cost reduction through optimization.

In order to achieve static hand gesture recognization within complex skin-like background regions in an effective and intelligent manner, this study proposed an integrated hand gesture recognition model based on the improved centroid watershed algorithm (ICWA) and a dual-channel convolutional neural network (DCCNN) structure. The effectiveness of this approach stemmed from more accurate segmentation of hand gestures from an original image by using the ICWA. The segmented image and the corresponding Local Binary Patterns (LBP) features extracted from the original image then serve as inputs for two channels of the devised DCCNN respectively for classification. The contributions of this study included an innovative method for reducing the image gradient difference while segmenting in the YCrCb color space, and the fusion of both Principal Component Analysis (PCA) for dimension reduction and a convexity detection process for identifying the secant line between the palm and arm. The devised DCCNN enables significant improvement on the static hand gesture classification accuracy by employing independent dual-convolution neural network framework for dealing with richer features at different scales. Tests and evaluations on benchmarking databases demonstrated that the devised models and techniques outperform classic methods with distinctive advantages when operating under challenging skin-like background conditions.
为了有效、智能地实现复杂类皮肤背景区域内的静态手势识别,本研究提出了一种基于改进形心分水岭算法(ICWA)和双通道卷积神经网络(DCCNN)结构的集成手势识别模型。该方法的有效性源于使用ICWA从原始图像中更准确地分割手势。然后将分割后的图像和从原始图像中提取的相应的局部二值模式(Local Binary Patterns, LBP)特征分别作为所设计的DCCNN的两个通道的输入进行分类。本研究的贡献包括在YCrCb色彩空间分割时减少图像梯度差异的创新方法,以及融合主成分分析(PCA)降维和识别手掌和手臂之间割线的凹度检测过程。设计的DCCNN通过采用独立的双卷积神经网络框架处理不同尺度上更丰富的特征,显著提高了静态手势分类的准确率。对基准数据库的测试和评估表明,所设计的模型和技术在具有挑战性的类似皮肤的背景条件下运行时,具有明显的优势,优于经典方法。
