The ongoing rapid growth of electricity over the past few decades greatly promotes the necessity of accurate electricity load forecasting. However, despite a great number of studies, electricity load forecasting is still an enormous challenge for its complexity. Recently, the developments of machine learning technologies in different research areas have demonstrated their great advantages. General vector machine (GVM) is a new machine learning model, which has been proven very effective in time series prediction. In this article, we apply it in electricity load forecasting. A detailed comparison with traditional back-propagation neural network (BP) is presented in this paper. To improve the load forecasting accuracy, we propose many methods to train the GVM model. Analysis of our approach on the historical Queensland electricity load dataset has demonstrated that GVM could achieve better forecasting results, which shows the strong potential of GVM for general electricity load forecasting.
过去几十年来,电力的持续快速增长极大地促进了准确电力负荷预测的必要性。然而,尽管开展了大量研究,电力负荷预测因其复杂性仍是一项巨大挑战。近来,机器学习技术在不同研究领域的发展已显示出其巨大优势。通用向量机(GVM)是一种新的机器学习模型,已被证明在时间序列预测中非常有效。本文将其应用于电力负荷预测。本文对其与传统的反向传播神经网络(BP)进行了详细比较。为了提高负荷预测的准确性,我们提出了许多训练 GVM 模型的方法。对昆士兰电力负荷历史数据集的分析表明,GVM 可以获得更好的预测结果,这表明 GVM 在一般电力负荷预测方面具有强大的潜力。

At present, the data classification based on SOA data exchange method of internet of things (IoT) data is not perfect, the effectiveness of data filtering is low, and the security of data exchange is poor. In this paper, the mass data of IoT are classified by transfer-boost method. The auxiliary training data are used to help source training data and build a reliable classifier to make the classifier more accurate in the test data. Hedge grammar is used to process massive data of heterogeneous IoT. The buffer mechanism is introduced to deal with the unstable data flow in the IoT, so as to enhance the effectiveness of data filtering, and realise the secure data exchange through modules such as server request, identity authentication and receiving data. Experimental results showed that the proposed model can improve the classification accuracy and data filtering effect, and achieve a more secure data exchange effect.

Aiming at the advantages of internet of things in coal mine application, in this paper, we propose a new method of mobile opportunity perception, which makes full use of underground mine mobile resources. Without adding extra sensing devices, the collaborative working mechanism of mobile nodes and fixed nodes is established. Accordingly, it builds environment opportunity perception and information transmission of the whole place in coal mine and achieves a comprehensive perception goal. By analysing the loss and redundancy perception probability between the mobile and fixed nodes, a novel sparse heterogeneous fusion network and its mixed node arrangement strategy and low-order error detection model between nodes are established. On this basis, to verify the superiority of strategy, the hardware design and experiments are carried out, which provides a new approach and idea for mining enterprises in sensing layer and transport layer application of internet of things.

It is difficult with traditional methods to realise real-time and robust detection of moving vehicles under complex traffic scenes. In this paper, a moving vehicle video detection method that combines ViBe and inter-frame difference is proposed. The proposed method improves the background update efficiency of the traditional ViBe method by adding a multi-threshold comparison step to the inter-frame difference method. The improved background update strategy can judge whether the detected pixel point belongs to the foreground or background, and dynamically adjusts the background update rate according to the inter-frame difference results. Experimental results showed the proposed method can effectively remove of "ghosting" phenomenon that occurs in traditional ViBe method and realise accurate and complete detection of the moving vehicle in video.

Topology control for constructive interference-based data dissemination in WSN 基于建设性干扰的WSN数据传播拓扑控制

Data dissemination is a fundamental service in wireless sensor networks. Traditional protocols often suffer severe medium contention problem or incur significant overhead in contention resolution. Constructive interference (CI) enables concurrent transmissions to interfere constructively, so as to enhance network performance. It has been proved that leveraging CI can achieve near-optimal network flooding latency. However, recent studies show that redundant nodes transmitting simultaneously may degrade the dissemination performance and also consume extra energy. Considering the limited energy of sensor nodes, how to choose the appropriate nodes for simultaneous transmission is important for CI-based data dissemination schemes. In this paper, we formulate this problem as a multi-objective combinatorial optimisation problem theoretically. Considering the complexity of the problem, we design a distributed greedy node selection algorithm to select suitable nodes which forward simultaneously based on CI in each time slot. The main idea of the algorithm is that, by maintaining RecSet and unRecSet in the two-hop neighbour, each node selects suitable nodes from RecSet to transmit simultaneously, such that the maximum number of nodes in unRecSet can receive the packet. Numerical simulations show the efficiency of our proposed algorithm.
数据传播是无线传感器网络的一项基本业务。传统协议经常出现严重的中等争用问题,或者在争用解决方面产生巨大的开销。CI (Constructive interference)是指使并发传输产生建设性干扰,从而提高网络性能。事实证明,利用CI可以实现近乎最佳的网络泛洪延迟。然而,最近的研究表明,冗余节点同时发送不仅会降低传播性能,还会消耗额外的能量。考虑到传感器节点能量有限,如何选择合适的节点同时传输是基于ci的数据传播方案的重要组成部分。本文从理论上将该问题表述为一个多目标组合优化问题。考虑到问题的复杂性,我们设计了一种分布式贪婪节点选择算法,在每个时隙中基于CI选择合适的节点同时转发。该算法的主要思想是,通过在两跳邻居中保持RecSet和unRecSet,每个节点从RecSet中选择合适的节点同时发送,从而使unRecSet中最大数量的节点可以接收到数据包。数值仿真结果表明了算法的有效性。

As one of the most applied EEG-based paradigms, motor imagery based brain-computer interface (MI-BCI) is used not only to control external devices, but also to help hemiplegic patients to reconstruct impaired motor function. However, in practical application of MI-BCI, users often face more varied external environments and complex cognitive activities, which could induce a high mental workload. This paper studied the effects of mental workload on motor imagery by designing a parallel task containing required motor and N-back task, taking motor execution as comparison. The experimental results showed that high mental workloads promoted the cognitive-motor process of motor imagery and restrained motor execution. Besides, the classification performance of MI-BCI was evaluated and compared at different mental workload levels between motor imagery and motor idle state. We also verified the possibility of detecting mental workload levels during motor imagery in offline analysis. The paper contributed to a wide range of MI-BCI applications and by exploring the cognitive-motor mechanism in motor imagery and execution.
基于运动意象的脑机接口(MI-BCI)是目前应用最广泛的基于脑电图的脑机接口模式之一,它不仅用于控制外部设备,还用于帮助偏瘫患者重建受损的运动功能。然而,在MI-BCI的实际应用中,使用者往往面临更加多变的外部环境和复杂的认知活动,这可能会导致较高的心理负荷。本文通过设计一个包含要求动作和N-back任务的并行任务,以动作执行为对照,研究了心理负荷对动作意象的影响。实验结果表明,高心理负荷促进了运动意象的认知运动过程,抑制了运动执行。此外,我们还评估和比较了运动想象和运动空闲状态在不同心理负荷水平下MI-BCI的分类性能。我们还验证了在离线分析中检测运动意象期间心理工作量水平的可能性。本文通过探索运动想象和执行的认知-运动机制,为MI-BCI的广泛应用做出了贡献。

In order to solve the privacy protection problem of individual big data, this paper proposes a hierarchical data trackback technique (HDTT). This technique can realise the data trackback through inter-domain and intra-domain path reconstruction without increasing the core network storage load. The main method is as follows: record the AS domain involved by data packets and IP address information with GBF data structure by use of idle part of packet header, determine the AS domain first with GBFAS data during the path reconstruction, and then determine the intra-domain router with GBFIP data to complete the data trackback. Finally, through the verification of Data Collect Treasure platform by project group, the contact ratio between inter-domain and intra-domain paths is up to over 98% and 92%, respectively, so HDTT technique can accurately reconstruct the data flow path, realise the data trackback and achieve the privacy protection of individual big data.
为了解决个体大数据的隐私保护问题,本文提出了一种分层数据追溯技术(HDTT)。该技术可以在不增加核心网存储负荷的情况下,通过域间和域内路径重构实现数据溯源。主要方法是:利用包头的空闲部分,用GBF数据结构记录数据包所涉及的as域和IP地址信息,在路径重构时先用GBFIP数据确定as域,再用GBFIP数据确定域内路由器,完成数据溯源。最后,通过项目组对数据采集宝平台的验证,域间路径和域内路径的接触率分别达到98%以上和92%以上,HDTT技术可以准确重构数据流路径,实现数据追溯,实现个体大数据的隐私保护。

Automatic melanoma diagnosis based on image processing can give more objective results. To facilitate examination for patients at home, we propose a new automatic melanoma diagnosis framework based on common images. Firstly, we use illumination assessment based on variational framework for Retinex (VFR) to filter the images with illumination problem caused by variation of capturing cameras viewpoint and ambient light. Secondly, the GrabCut algorithm based on colour difference is used to segment lesion area. It can complete segmentation automatically and efficiently. Thirdly, we use convolutional neural network (CNN) to extract high-level features and choose support vector machine (SVM) classifier to complete melanoma classification. Compared to hand-craft features, CNN can acquire deep information of images. Because of the lack of medical images, the SVM classifier is better than other classifiers. Finally, we validated our approach from different perspectives and the accuracy is increased by about 5% over other methods.

Wireless sensor networks have been pushed to the forefront in recent decades owing to the advent of the internet of networks. There exist some crucial parameters which affect the reliability and lifetime performance of typical applications in wireless sensor networks. In this paper, we implement the single-hop protocol with J-Sim simulation tool. Then, we analyse the closure relationships among the density, radius, reliability and lifetime and disclose the trade-off analysis results among them. Next, we propose that two intelligent evaluation models can be applied to under such situations. Thus, wireless sensor network users can predict the lifetime and reliability directly and simulations will be not necessary. This paper also discusses the disadvantages of this approach.

Thus, wireless sensor network users can predict the lifetime and reliability directly and simulations will be not necessary. This paper also discusses the disadvantages of this approach.","PeriodicalId":412308,"journal":{"name":"Int. J. Embed.

Strapdown inertial navigation system (SINS) initial alignment error model is presented under moving base. SINS navigation error models and the integrated navigation error models are proposed. The state observability during the initial alignment under moving base was thoroughly studied according to the piece-wise constant system method and singular value decomposition method. Simulation experiments were carried out under different vehicle movements with same integration and different integration with same vehicle movements respectively. Simulation experiments show that the observability degree of states variables can be improved under linear or rotation movement, furthermore, the outer measurements aided SINS can also improve the observability degree of system state variables accordingly. The observability degree increases of state variables improve the accuracy of estimation and the speed of convergence of Kalman filter applied in the integrated inertial navigation system.
提出了捷联惯导系统在动基条件下的初始对准误差模型。提出了捷联惯导系统导航误差模型和组合导航误差模型。采用分段常系统法和奇异值分解法,对移动基座下初始对准时的状态可观测性进行了深入研究。分别在相同积分的不同车辆运动和相同车辆运动的不同积分下进行仿真实验。仿真实验表明,在直线运动和旋转运动下,系统状态变量的可观测性都得到了提高,外部测量辅助捷联惯导系统状态变量的可观测性也得到了相应的提高。状态变量可观测度的增加提高了卡尔曼滤波在组合惯性导航系统中的估计精度和收敛速度。
