An odd number of one-wavelength ring resonators are proposed to be directly series-connected along a quarter-wavelength of their sides to exhibit a bandpass response with very high rejection level. As each ring presents a dual-mode response, the order of the overall bandpass response will be equal to two times the number of rings being used. Furthermore, the pseudo-elliptic characteristics of the ring resonators will enhance the selectivity of the resulting filter since a transmission zero is obtained at both sides of the passband. An application of the concept is implemented for the case of three series-connected rings that exhibits a 6th order bandpass response centered at 2 GHz. Fabricated on epoxy-glass substrate, the results show a very good agreement between the simulation and measurement with a very good rejection level surpassing 50 dB up to 3.5 GHz.
提出了奇数个单波长环形谐振器沿其侧面的四分之一波长直接串联,以显示具有非常高抑制电平的带通响应。由于每个环呈现双模响应,因此整个带通响应的顺序将等于所使用环数的两倍。此外,环形谐振器的伪椭圆特性将提高所得到的滤波器的选择性,因为在通带的两侧都获得了传输零。在三个串联环的情况下实现了该概念的应用,该环具有以2ghz为中心的6阶带通响应。在环氧玻璃基板上制作,仿真结果与测量结果吻合良好,抑制电平在3.5 GHz范围内超过50 dB。

This paper discusses identification of an actuator model, which has been built inside a two-pole induction motor in order to control rotor vibrations. The methods used for identification are prediction error method and cultural particle swarm optimization with mutation. The first-mentioned method produces a black box model with correspondence to input-output measurements. The second method is used to identify parameters of a linear time-invariant state-space model, which is based on electromechanical equations. The results are compared in time domain and in frequency domain.

Multicast is a well-known protocol that has been tested to be a highly effective method to deliver real time applications over the network. In this paper, two Virtual Private Network (VPN) based technologies are considered in delivering real-time based applications namely Multiprotocol Label Switching (MPLS) and Asynchronous Transfer Mode (ATM). The performance comparison of video multicast of the two technologies is described. Both platforms were modeled and simulations executed with multicast protocol enabled. For real time traffic, selected parameters were carefully defined and configured such as delay, throughput and packet loss. The objective of this study is to compare performance of MPLS and ATM based on these selected parameters, particularly in the case of delivering video traffic in the presence of congestion. The study showed that with VPN enabled on both technologies, MPLS had performed better than ATM in terms of throughput and packet drop.

In this paper, we presents Electromyogram (EMG) signal based human emotion classification using K Nearest Neighbor (KNN) and Linear Discriminant Analysis (LDA). Five most dominating emotions such as: happy, disgust, fear, sad and neutral are considered and these emotions are induced through Audio-visual stimuli (video clips). EMG signals are obtained by using 3 electrodes over 10 trials per emotion and preprocessed by using Butterworth 6th order filter to remove noises and external interferences. EMG signals on decomposed into four different frequency ranges ((8 Hz– 16 Hz), (16 Hz– 31 Hz) and (16 Hz– 63 Hz)) using Discrete Wavelet Transform (DWT). The ststistical features extracted from the above frequency bands are mapped into five different emotions using two simple classifiers such as KNN and LDA. The value of K in KNN is varied randomly, and maximum classification rate is achieved at K=3. KNN classifier gives the highest classification rate on four emotions (disgust, happy, fear and neutral) different emotions and LDA on sad emotion. The maximum classification rate of disgust, happy, fear neutral, and sad are 90.83%, 100%, 94.17%, and 90.28% and 43.89%, respectively are achieved using KNN and LDA. The results from the proposed methodology are promising and female are easily evoked by different emotional stimuli compared to male.
本文提出了基于K最近邻(KNN)和线性判别分析(LDA)的肌电图(EMG)信号的人类情感分类方法。考虑了五种最主要的情绪,如:快乐,厌恶,恐惧,悲伤和中性,这些情绪是通过视听刺激(视频剪辑)引起的。每个情绪用3个电极10次试验获得肌电信号,并使用巴特沃斯6阶滤波器进行预处理,去除噪声和外界干扰。利用离散小波变换(DWT)将肌电信号分解为(8hz ~ 16hz)、(16hz ~ 31hz)和(16hz ~ 63hz)四个不同的频率范围。从上述频带提取的统计特征使用两个简单的分类器(如KNN和LDA)映射到五种不同的情绪。KNN中K的值是随机变化的,在K=3时分类率最大。KNN分类器对厌恶、快乐、恐惧和中性四种情绪的分类率最高,对悲伤情绪的分类率为LDA。KNN和LDA对厌恶、快乐、恐惧中性和悲伤的分类率分别达到90.83%、100%、94.17%,分别达到90.28%和43.89%。结果表明,与男性相比,女性更容易被不同的情绪刺激所诱发。

This project focuses on the occurrence of Ground ULF signal prior due to the fact that ULF frequency band is considered as most promising frequency range in ground base observation where electromagnetic earthquake precursors may be found hence the study of ULF magnetic wave is very significant. An earthquake (also known as a tremor or temblor) is the result of a sudden release of energy in the Ear th's crust that creates seismic waves. In order to reveal possible earthquake precursor through the changes of ULF signal, 2 set of real time data from California region is used as a study case. The data was taken from Quakefinder websites which owned magnetometer station along the California fault region. The observation was made several days before and on the day of the earthquake event occurred. The results obtained, demonstrated the theory that magnetometer may detect anomaly in ULF signal several days or a few hours before main shock. The data is shown in the form of Pc3/4 waveform and it is broken down by the scale of the amplitude into graph. The maximum and minimum amplitude taken from the graph showed anomaly of ULF and its correlation to space ULF have been discussed.
由于超低频频带被认为是地面观测中最有希望发现电磁地震前兆的频率范围,因此对超低频电磁波的研究具有十分重要的意义。地震(也被称为震颤或地震)是地壳中突然释放能量产生地震波的结果。为了通过ULF信号的变化揭示可能的地震前兆,本文以加利福尼亚地区的2组实时数据为例进行了研究。这些数据来自地震探测者网站,该网站拥有沿加州断层地区的磁力计站。这次观测是在地震发生的前几天和当天进行的。结果表明,磁力计可以在主震发生前数天或数小时内探测到超低频波信号的异常。数据以Pc3/4波形的形式显示,并按幅度的比例将其分解成图形。本文还讨论了该异常图的最大和最小幅值及其与空间超低场的相关性。

Wireless power transmission is a process that takes place in any system where electrical energy is transmitted from a power source to an electrical load without a wired connection. Wireless transmission is ideal in cases where instantaneous or continuous energy transfer is needed, but interconnecting wires are inconvenient, hazardous, or impossible. Antenna has become the most vital element in any RF system due to its capability as a radio wave transceiver. A properly designed antenna is desirable to ensure efficient transfer of energy. This paper proposes a helical antenna design for wireless power transmissions through radio wave frequency of 300 MHz to 400 MHz. The antenna is being designed and simulated using CST microwave software. The parameters highlighted in this paper include return loss, voltage standing wave ratio, and radiation pattern. Preliminary findings indicate that the helical antenna design is suitable for wireless power transmission. Hence, the research has a prospective future of being extended for fabrication and prototype testing.
无线电力传输是一种发生在任何系统中的过程,其中电能从电源传输到电气负载而无需有线连接。在需要瞬时或连续能量传输的情况下,无线传输是理想的,但互连电线不方便、危险或不可能。由于天线作为无线电波收发器的能力,它已成为任何射频系统中最重要的元件。设计合理的天线是保证能量有效传输的必要条件。本文提出了一种利用无线电波频率为300 ~ 400 MHz进行无线电力传输的螺旋天线设计。利用CST微波软件对天线进行了设计和仿真。本文重点讨论的参数包括回波损耗、电压驻波比和辐射方向图。初步结果表明,螺旋天线设计适合无线电力传输。因此,该研究具有扩展到制造和原型测试的前景。

Wireless transmission is ideal in cases where instantaneous or continuous energy transfer is needed, but interconnecting wires are inconvenient, hazardous, or impossible. Antenna has become the most vital element in any RF system due to its capability as a radio wave transceiver. A properly designed antenna is desirable to ensure efficient transfer of energy. This paper proposes a helical antenna design for wireless power transmissions through radio wave frequency of 300 MHz to 400 MHz. The antenna is being designed and simulated using CST microwave software. The parameters highlighted in this paper include return loss, voltage standing wave ratio, and radiation pattern. Preliminary findings indicate that the helical antenna design is suitable for wireless power transmission. Hence, the research has a prospective future of being extended for fabrication and prototype testing.","PeriodicalId":346890,"journal":{"name":"2011 IEEE International Conference on System Engineering and Technology","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128512626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this research is to propose a new location registration procedure for System Architecture Evolution (SAE) which is the core network architecture of 3GPP's future Long Term Evolution (LTE) wireless communication standard. Under the proposed procedure, the authentication between access systems supporting different IP versions is carried out. A signaling message for a new location registration procedure is developed to evaluate the performance of the signaling procedure. The numerical results showed that the proposed procedure reduces the registration costs and latency for location registration. Therefore, this procedure results in significant performance improvements for SAE.
