This brief proposes an improved XOR logic gate and a novel full adder. The presented XOR has simple structure which consists of 2 CMOS transistors and 4 memristors, and it reduces 4 CMOS transistors compared with the previous. In addition, the novel full adder consists of 7 CMOS transistors and 10 memristors. This novel full adder reduces 8 CMOS transistors and 2 memristors, which means the size of the circuit is smaller and power consumption is lower. Through analysis and simulation, the feasibilities of the improved XOR logic gate and novel full adder are demonstrated.

The robust delay feedback control problems for discrete-time stochastic interval systems(DTSISs) with time-delay and Markovian jumps are studied in this paper. Firstly, the dissipativity for DTSISs with time delay and Markovian jumps is analyzed, then based on this, the robust delay-feedback controller, which includes not only the instantaneous state information but also the delay state information, is designed. Finally, we give a numerical example with simulations to illustrate the correctness of the obtained results and the effectiveness of the designed controller.

Effective and efficient ship detection is a prerequisite in inland video surveillance, e.g. to track the target ship from frame to frame and to analyze the tracked ship to recognize its behavior. In this paper, a real-time inland ship detection algorithm called MEADGS is proposed, which is based on dynamic group sparsity and background subtraction method. The background and foreground image are reconstructed directly based on enhanced adaptive dynamic group sparsity (EAdaDGS) algorithm. The background dictionary is updated in real time by the current background image when current frame is a key frame. Meanwhile, the efficiency of our proposed method is further improved by multi-resolution detection procedure. The ships are located in low resolution, and detected accurately in the specified area of high resolution. The experimental results show that our proposed method obtains higher-quality, with a 7.6% margin over the second best method performance.

Automatic spoken digit recognition is one of the important areas in speech recognition. Local language spoken digits recognition is the next stage in this technological advancement. This paper presents a new approach for Pashto digits recognition using spectral and prosodic based feature extraction. Very little or almost no work has been done in Pashto spoken digit recognition. Thats why no standard Pashto digit corpus was available online. A database of 150 native speakers from 0 (sefor) to 9 (naha) including 75 males and 75 females is developed. Creation of corpus is one of the main contributions of this work. To the best of authors knowledge support vector machine (SVM) is used for the first time in Pashto digits classification and compared with K-nearest neighbor (KNN) classifier. Out of 150, 110 speakers feature set are used for training purposes and the remaining 40 speakers feature set are used for testing. The results obtained from the proposed method are very satisfactory and achieved 91.5% over all accuracy.

Recently, the quadcopter configuration is becoming prevalent for both civilian and military applications, and research is continuing to improve its controllability. However, most the control methodologies depend on accurate system models which are derived from six degrees of freedom nonlinear system dynamics and they generally do not consider realistic outdoor perturbations and uncertainties. As a solution, model-free data-driven system identification and controlling of quadcopter have been refined in this paper. This nonlinear multiple input-multiple output system identification is proliferated using a fuzzy clustering model. The accuracy of the identification is seen to very high. The results of a PID controller used in conjunction with the identified fuzzy model is also presented. The PID controller with the fuzzy identified model is seen to precisely follow the commanded signals.
最近,四轴飞行器的配置在民用和军事应用中变得越来越普遍,研究正在继续提高其可控性。然而,大多数控制方法依赖于精确的系统模型,这些模型是由六自由度非线性系统动力学推导出来的,它们通常不考虑实际的室外摄动和不确定性。为此,本文对无模型数据驱动的四轴飞行器系统识别与控制进行了改进。利用模糊聚类模型扩展了非线性多输入-多输出系统辨识。这种鉴定的准确性被认为是非常高的。并给出了PID控制器与所识别的模糊模型结合使用的结果。采用模糊辨识模型的PID控制器可以精确地跟踪指令信号。

We study a single location supply system for repairable spare parts. The system consists of a multi-server repair shop and inventory with ready-to-use spare parts. When a failed part is received, a new (or as-good-as-new) replacement part is sent back, and the failed part is forwarded to the repairshop. In the case of unavailability of spare parts, failed requests are backordered and fulfilled when a ready-for-use part of the same type is received from the repairshop. The repair shop has several multi-skilled parallel servers (technicians) that are capable of handling certain types of spares. In this paper, we propose a Particle Swarm Optimization heuristic combined with Discrete-Event Simulation for optimizing the cross-training policy (skill assignment scheme) while minimizing the total system cost (consisting of inventory costs, backorder penalty cost, server cost and skill cost).

This paper investigates FTC (finite-time consensus) problem of nonlinear MAC (multi-agent system) with disturbance via impulsive control protocol, where the states of agents can be updated by the state of itself and the state of its neighbor at certain discrete time constants. Some sufficient conditions are established via the impulsive control theory and the algebraic graph theory. What's more, the setting time for consensus is formulated by eigenvalues of Laplacian matrix, control gain and impulse interval. Numerical simulations demonstrate the availability of the theoretical results.

The intention of this work is to show how logic of plausible reasoning (LPR) can be successfully used for solving complex decision problems. In the following sections a decision involve the use of LPR is described, and then its operation was illustrated on the example of an expertize concerning the choice of technology for making metal products. A knowledge base on the examined group of materials is presented and practical functioning of the system for the choice of a metal processing technology is disclosed. Typical scenarios of the system usage are presented, serving at the same time as a tool to verify its functionality. In particular, it is expected to create a module allowing automatic generation of rules to the knowledge base, and introduce machine learning to achieve optimal parameters of the inference process. The approach proposed in this study can be applied to a broad class of metal products, but in every case it should take into account the speciffic nature of a particular group of products and technological parameters of the materials used.

In this paper, a feature selection system is introduced applies the whale optimization algorithm (WOA). WOA is a recently introduced meta-heuristic optimization algorithm that mimics the natural behavior of the humpback whales. The proposed model applies the wrapper-based method to reach the optimal subset of features. This technique was applied to find the best feature subset that maximizes the accuracy of the classification while preserving the minimum number of features. The proposed model is compared with the particle swarm optimization (PSO) and genetic algorithm (GA) using a number of assessment indicators on 16 different data-sets from UCI data repository. The results demonstrate the advantage of the introduced algorithm compared to the other optimizers.
本文介绍了一种应用鲸鱼优化算法(WOA)的特征选择系统。WOA是最近引入的一种元启发式优化算法,它模仿了座头鲸的自然行为。该模型采用基于包装器的方法来获得最优的特征子集。该技术用于寻找在保留最小特征数量的同时使分类精度最大化的最佳特征子集。在UCI数据库的16个不同数据集上,采用多个评价指标,将该模型与粒子群算法(PSO)和遗传算法(GA)进行了比较。结果表明,与其他优化器相比,所引入的算法具有优势。

WOA is a recently introduced meta-heuristic optimization algorithm that mimics the natural behavior of the humpback whales.
