Traffic monitoring plays a vital role in the current world. Previously, stationary data collectors such as video cameras and induction loops were employed for this task. However, the availability of unmanned aerial vehicles (UAV) has opened up new horizons for this task and numerous research projects are being conducted in this field. But object detection and tracking become a challenging task in the case of aerial images due to the presence of high density of objects, challenging view angles, different illumination changes, and varying altitudes of the drone. In this paper, we propose a method for detecting vehicles and also tracking them through the use of cascade classifier and centroid tracking. We have also incorporated georeferencing and coregistration of acquired images and then proceeded on to extract lanes. After segmenting out the region of interest, we proceeded with the detection and tracking tasks.
交通监控在当今世界起着至关重要的作用。以前,固定式数据收集器(如摄像机和感应回路)被用于这项任务。然而,无人驾驶飞行器(UAV)的可用性为这一任务开辟了新的视野,许多研究项目正在这一领域进行。但是,由于存在高密度的物体、具有挑战性的视角、不同的照明变化以及无人机的高度变化,在航空图像的情况下,物体检测和跟踪成为一项具有挑战性的任务。在本文中,我们提出了一种通过串级分类器和质心跟踪来检测和跟踪车辆的方法。我们还对获取的图像进行了地理参考和共配准,然后继续提取车道。在分割出感兴趣的区域后,我们继续进行检测和跟踪任务。

Person re-identification (Re-ID) is a process to re-identify a person if he has been already seen by a camera network. Since start the convolutional neural networks (CNNs) are dominantly being used to solve the person Re-ID problem. The default limitation of CNNs i.e., local receptive field, prohibits the network to learn the distinctive global dependencies at initial layers. This study proposes a self-attention based deep architecture that learns global dependencies at each network layer to address CNN's limitation. Additionally, the introduction of a novel contextual learning module called Attention Drop Block (ADB) supports learning of less attentive areas of an image as well. The proposed model is evaluated on two public Re-ID benchmarks Market1501 and DukeMTMC-ReID, and outperformed all CNN baseline Re-ID models. The implementation and trained models are made publicly available at https://git.io/JYRE3.
人员再识别(Re-ID)是一个过程,重新识别一个人,如果他已经被一个摄像头网络看到。自开始以来,卷积神经网络(cnn)主要用于解决人的身份识别问题。cnn的默认限制,即局部接受域,禁止网络在初始层学习独特的全局依赖关系。本研究提出了一种基于自关注的深度架构,该架构在每个网络层学习全局依赖关系,以解决CNN的局限性。此外,还引入了一种新的上下文学习模块,称为注意力下降块(ADB),它也支持对图像中注意力不那么集中的区域进行学习。该模型在两个公共Re-ID基准市场1501和DukeMTMC-ReID上进行了评估,并优于所有CNN基准Re-ID模型。实现和训练过的模型可以在https://git.io/JYRE3上公开获得。

Parts-of-Speech (POS) tagging is a highly encouraged research topic in the field of Natural Language Processing. POS entails numerous practical applications such as text indexing, information retrieval, corpus tagging for research, and linguistic work. This paper outlines multiple methods for part-of-speech tagging in Roman Urdu. Sufficient work and relevant required corpora are not available for Roman Urdu. We have identified that there are several parts-of-speech classes in the Urdu Language, with limited access to a well-annotated corpus. A manually verified corpus has been used to evaluate and report multiple methods for the said task. Our experiments deal with twenty-three unique parts-of-speech classes based on the contextual requirements of the Urdu Language. Our experiments include several methods built upon artificial neural networks, based on approaches such as multi-layered neural networks, feedback recurrent networks, and self-attention models. The corpus we used is not domain specific and covers several topics of Pakistani interest. Our experiments varied to a certain degree in the success demonstrated and outperformed numerous baseline models of machine learning and deep learning.
词性标注是自然语言处理领域一个备受关注的研究课题。POS包含许多实际应用,如文本索引、信息检索、语料库标记研究和语言学工作。本文概述了罗马乌尔都语词性标注的多种方法。罗马乌尔都语没有足够的工作和相关所需的语料库。我们已经确定,乌尔都语中有几个词性类,对注释良好的语料库的访问有限。手动验证的语料库已用于评估和报告上述任务的多种方法。我们的实验基于乌尔都语的语境要求,处理了23个独特的词类。我们的实验包括几种基于人工神经网络的方法,如多层神经网络、反馈循环网络和自注意模型。我们使用的语料库不是特定领域的,涵盖了巴基斯坦感兴趣的几个主题。我们的实验在一定程度上成功地展示并超越了许多机器学习和深度学习的基线模型。

Daily gun and knife related incidents are increasing due to lack of security check. In most of the places CCTV cameras are being installed however they require surveillance all the time. It is difficult due to limitations of humans in vigilant monitoring of the surveillance videos. The need of automated weapon detection is evident to limit and reduce these types of incidents. The proposed approach is mainly focused on developing an automated weapon detection system to detect different types of firearms and knives. In order to detect these types of incidents, we used a YOLOv5 deep learning model on a self collected dataset. The evaluation of the proposed approach shows its ability in the accurate detection of these weapons with an F1 score of 0.95 in CCTV video.
由于缺乏安全检查,每天与枪支和刀具有关的事件正在增加。在大多数地方都安装了闭路电视摄像机,但是他们需要一直监控。由于人类的局限性,很难对监控视频进行警惕监控。为了限制和减少这类事件,显然需要自动武器探测。建议的方法主要集中在开发一种自动武器检测系统,以检测不同类型的枪支和刀具。为了检测这些类型的事件,我们在自收集的数据集上使用了YOLOv5深度学习模型。对该方法的评估表明,该方法能够准确地检测出这些武器,在CCTV视频中的F1得分为0.95。

Roman Urdu is an informal form of writing the Urdu language which is written in Latin script. It is the language most widely used on the internet, social media, and text messaging by native Urdu speakers. The problem that arises with Roman Urdu is an inconsistent way of writing by different people. No standard rules are defined for writing Roman Urdu which makes it very difficult to perform Natural Language Processing. To overcome this issue, the text needs to be normalized to perform effective analysis. Therefore, this work provides a Roman Urdu dictionary that works as the foundation for processing Roman Urdu. It also proposes a model for the lexical normalization of Roman Urdu text.
罗马乌尔都语是用拉丁字母书写的乌尔都语的非正式形式。它是互联网、社交媒体和母语为乌尔都语的人发短信时使用最广泛的语言。罗马乌尔都语出现的问题是不同人的书写方式不一致。没有为书写罗马乌尔都语定义标准规则,这使得执行自然语言处理非常困难。为了克服这个问题,需要对文本进行规范化以进行有效的分析。因此,这项工作提供了一个罗马乌尔都语词典,作为处理罗马乌尔都语的基础。并提出了罗马乌尔都语文本的词汇规范化模型。

Machine learning (ML) has no doubt virtually helped in nearly all fields of life, including medical sciences. ML models are now being trained, tested and developed with the help of information gained from Electroencephalogram (EEG) Signals. Neural Networks (NN) are being used specifically in this regard to exploit their image classification ability. A special class of NN called Transfer Learning (TL), is used to enhance the capability of NNs. In this paper, EEG signals are extracted and used to classify Left or Right Motor Images of the brain using Inception V3 and VGG 16 models. We try to enhance the accuracy of these TL Models by exploiting a different methodology as compared to other available statistical methods available in the research community. For the said purpose, a dataset from Brain-Computer Interface (BCI) Competition IV 2b was used. EEG signals are extracted and transformed into Short Time Fourier Transform (STFT) images. These STFT images are labeled with either Left or Right Motor Imagery (MI) Class. The transfer learning models are trained using these STFT images and results are also compared with a state-of-the art research, implementing Capsule Networks.
毫无疑问,机器学习(ML)几乎在生活的所有领域都有帮助,包括医学。机器学习模型现在正在通过从脑电图(EEG)信号中获得的信息进行训练、测试和开发。神经网络(NN)在这方面被专门用于开发其图像分类能力。一种特殊的神经网络称为迁移学习(TL),用于增强神经网络的能力。本文采用Inception V3和VGG 16模型提取脑电信号,并将其用于脑左、右运动图像的分类。我们试图通过利用不同的方法来提高这些TL模型的准确性,与研究界其他可用的统计方法相比。为了上述目的,使用了脑机接口(BCI)竞赛IV 2b的数据集。对脑电信号进行提取并进行短时傅里叶变换(STFT)。这些STFT图像被标记为左或右运动图像(MI)类。使用这些STFT图像训练迁移学习模型,并将结果与实施胶囊网络的最新研究进行比较。

The future Internet architecture, like Named-Data Network (NDN), converts host-based network structures into content-based network structures. Through this transformation, the overall network performance and efficiency are increased. Furthermore, every router in the NDN uses a caching mechanism. Thus, the cache replacement policy used by the NDN routers is also a significant determinant of the NDN's overall performance. Therefore, several types of research have been conducted about the NDN's cache replacement policy. In this article, a light-weighted cache replacement strategy is proposed that overcomes the limitations and drawbacks of the Least Frequently Used (LFU) cache policy. The proposed strategy applies variables, based on real-time producer popularity. Additionally, it can be observed through extensive simulations that the proposed strategy provides better results and shows a higher cache hit ratio as compared to the existing cache policies.
未来的Internet架构,如命名数据网络(NDN),将基于主机的网络结构转换为基于内容的网络结构。通过这种改造,提高了网络的整体性能和效率。此外,NDN中的每个路由器都使用缓存机制。因此,NDN路由器使用的缓存替换策略也是NDN整体性能的重要决定因素。因此,对NDN的缓存替换策略进行了几种类型的研究。本文提出了一种轻量级缓存替换策略,克服了LFU缓存策略的局限性和缺点。所提出的策略采用基于实时制作人受欢迎程度的变量。此外,通过大量的模拟可以观察到,与现有的缓存策略相比,所提出的策略提供了更好的结果,并且显示出更高的缓存命中率。

Validation of Small Signal Model of an LLC Resonant Converter Based HVDC Modulator 基于LLC谐振变换器的高压直流调制器小信号模型验证

Resonant converter based power supplies are widely deployed in many industrial applications for their high efficiency and high power density. For control and regulation of the output voltage in resonant converters, frequency modulation (FM) is an intuitive and preferred method. However, the control-input-to-output transfer function is non-linear function of the operating frequency. The mean operating frequency determines the DC gain and bandwidth of the system for small signal perturbations. In this regard, third order non-linear model for LLC resonant converters is proposed in the literature. At a fixed operating point (i.e. a fixed output voltage corresponding to a particular operating frequency), the model can be treated as fairly linear for small perturbations. It is observed that the DC gain and bandwidth at different operating points is quite different, so deciding an appropriate operating point for a particular application is an important design choice. This research considers the small signal model of an 8.8kV/2A LLC resonant converter designed with resonant frequency ($f_{r}$) of 22.7kHz and quality factor (Q)=4 for an industrial magnetron as a specific load. The model is validated through simulations and hardware experiments using the LLC resonant converter. For our specific system DC gain at $f_{r}$ is - 65dB and bandwidth is 310Hz. DC gain and bandwidth of the system at different operating frequencies give an insight to decide the appropriate operating point. Hence, this work offers a strong foundation for a controller design for the LLC resonant converter under consideration.
基于谐振变换器的电源以其高效率和高功率密度的特点被广泛应用于许多工业领域。对于谐振变换器的输出电压的控制和调节,调频(FM)是一种直观和首选的方法。但是,控制输入输出传递函数是工作频率的非线性函数。对于小信号扰动,平均工作频率决定了系统的直流增益和带宽。在这方面,文献中提出了LLC谐振变换器的三阶非线性模型。在固定的工作点(即对应于特定工作频率的固定输出电压),对于较小的扰动,该模型可以视为相当线性。可以看出,不同工作点的直流增益和带宽有很大的不同,因此为特定应用选择合适的工作点是一个重要的设计选择。本文以工业磁控管为特定负载,以谐振频率($f_{r}$)为22.7kHz,质量因子(Q)=4设计的8.8kV/2A LLC谐振变换器的小信号模型为研究对象。利用LLC谐振变换器进行了仿真和硬件实验,验证了该模型的有效性。对于我们的特定系统,f_{r}$的直流增益为- 65dB,带宽为310Hz。系统在不同工作频率下的直流增益和带宽为确定合适的工作点提供了依据。因此,这项工作为正在考虑的LLC谐振变换器的控制器设计提供了坚实的基础。

With immense population growth in recent years, social data is growing at a rapid pace, which in turn can prove to be a rich source of hidden information. This work focuses on identifying user interest in electronic products, especially smartphones, using social data. This will help electronic businesses in the personalized marketing of their products. From the literature, most of the existing approaches attempted to identify user interest based on their ratings. In our understanding, the contents of reviews are equally important in identifying people's interests. Therefore, in this paper, we proposed a framework that identifies user interests based on their reviews and their ratings. Moreover, it performs an analysis of the aforementioned reviews, and profiles user interest. To achieve this, we used website data, written in the Roman Urdu language. To the best of our knowledge, very limited research has been carried out on the Roman Urdu dataset, as it is considered a low-resource language. Concerning our methodology, we first performed topic modeling using Latent Dirichlet Allocation (LDA), Bidirectional Encoder Representations from Transformers (BERT), and a hybrid of both. Based on the identified topics, we performed user interest profiling based on the probabilities of each model/brand using the Top2Vec model. We compared our results of topic modeling using reviews and reviews plus ratings. For topic modeling, we measure coherence score which we observe 52% for the hybrid approach while 47% and 45% for “BERT” and “LDA” respectively. Finally, For topic modeling, we perform human-based validation by comparing human-identified topics with the ones identified by our model.
随着近年来人口的巨大增长,社会数据正在快速增长,这反过来又可以证明是一个丰富的隐藏信息来源。这项工作的重点是利用社交数据识别用户对电子产品,尤其是智能手机的兴趣。这将有助于电子企业对其产品进行个性化营销。从文献来看,大多数现有的方法都试图根据用户的评分来确定用户的兴趣。在我们的理解中,评论的内容对于确定人们的兴趣同样重要。因此,在本文中,我们提出了一个基于用户评论和评分来识别用户兴趣的框架。此外,它还对前面提到的评论进行分析,并对用户的兴趣进行分析。为了做到这一点,我们使用了用罗马乌尔都语写的网站数据。据我们所知,对罗马乌尔都语数据集进行了非常有限的研究,因为它被认为是一种低资源语言。关于我们的方法,我们首先使用潜在狄利克雷分配(LDA),变形金刚的双向编码器表示(BERT)以及两者的混合进行主题建模。基于识别的主题,我们使用Top2Vec模型基于每个模型/品牌的概率执行用户兴趣分析。我们使用评论和评论加评级来比较主题建模的结果。对于主题建模,我们测量了一致性得分,我们观察到混合方法的一致性得分为52%,而“BERT”和“LDA”的一致性得分分别为47%和45%。最后,对于主题建模,我们通过将人类识别的主题与我们的模型识别的主题进行比较来执行基于人类的验证。

The use of technology is increasing day by day as it is helping in daily life issues in lesser time. The children these days prefer using technology more than any other medium of learning. Many researchers have incorporated gamification in educational application to enhance the value of such applications and to attract students to use the application which in turn enhance their learning performance. This research focuses on the children learning Qaida applications which involve gamification so that children can have more attraction and interest in learning the most important Islamic religious book Quran. The comparison of different gaming elements in m- learning applications is done and included in a prototype of Gamified Quran. The prototype has been tested by an experiment and the output of learning performance has been measured with the help of multiple tests and it turned out to have positive impact on learning performance of the children.
技术的使用日益增加,因为它在更短的时间内帮助解决日常生活问题。现在的孩子们更喜欢使用技术而不是其他任何学习媒介。许多研究者将游戏化融入到教育应用中,以提高这些应用的价值,吸引学生使用这些应用,从而提高他们的学习成绩。本研究的重点是儿童学习涉及游戏化的基地组织应用程序,使儿童对学习最重要的伊斯兰宗教书籍《古兰经》更有吸引力和兴趣。对移动学习应用中不同的游戏元素进行了比较,并将其包含在游戏化古兰经的原型中。通过实验对原型进行了测试,并通过多次测试对学习成绩的输出进行了测量,结果表明对儿童的学习成绩有积极的影响。
