Although many cross platform mobile development software used a trans-compiler-based approach, it was very difficult to generalize it to work in both directions. For example, to convert between Java for Android Development and Swift for iOS development and vice versa. This is due to the need of writing a specific parser for each source language, and a specific code generator for each destination language. Neural network-based models are used successfully to translate between natural languages, including English, French, German any many others by providing enough datasets and without the need of adding language specific code for understanding and generation. In this paper, a source code converter based on the Neural Machine Translation Transformer Model that can translate from Java to Swift and vice versa is introduced. A synthesized dataset is used to train the model, the pipeline used for the translation as well as the code synthesis procedure throughout the work are illustrated. Initial results are promising and give motivation to further enhance the proposed tool.
尽管许多跨平台移动开发软件使用基于编译器的方法,但很难将其推广到两个方向。例如,在Android开发的Java和iOS开发的Swift之间进行转换,反之亦然。这是因为需要为每种源语言编写特定的解析器,并为每种目标语言编写特定的代码生成器。基于神经网络的模型被成功地用于自然语言之间的翻译,包括英语、法语、德语和许多其他语言,通过提供足够的数据集,而不需要添加语言特定的代码来理解和生成。本文介绍了一种基于神经网络机器翻译转换器模型的源代码转换器,该转换器可以在Java语言和Swift语言之间进行转换。使用合成的数据集来训练模型,说明了翻译所用的管道以及整个工作中的代码合成过程。初步结果是有希望的,并为进一步加强所建议的工具提供了动力。

Detection of the lane boundary is the primary task in order to control the trajectory of an autonomous car. In this paper, three methodologies for lane detection are discussed with experimental illustration: Blob analysis, Hough transformation and Birds eye view. The next task after receiving the boundary points is to apply a control law in order to trigger the steering and velocity control to the motors efficiently. In the following, a comparative analysis is made between different tuning criteria to tune PID controller for Lane Keeping Assist (LKA). In order to receive the information of the environment a camera is used that sends wireless data to Simulink through Raspberry-Pi (R-Pi). The data is processed by the controller that transmits the desired output control to arduino through serial communication.

The rising interest in assistive and autonomous driving systems throughout the past decade has led to an active research community in perception and scene interpretation problems like lane detection. Traditional lane detection methods rely on specialized, hand-tailored features which is slow and prone to scalability. Recent methods that rely on deep learning and trained on pixel-wise lane segmentation have achieved better results and are able to generalize to a broad range of road and weather conditions. However, practical algorithms must be computationally inexpensive due to limited resources on vehicle-based platforms yet accurate to meet safety measures. In this approach, an encoder-decoder deep learning architecture generates binary segmentation of lanes, then the binary segmentation map is further processed to separate lanes, and a sliding window extracts each lane to produce the lane instance segmentation image. This method was validated on a tusimple data set, achieving competitive results.
在过去的十年中,人们对辅助驾驶和自动驾驶系统的兴趣日益浓厚,这导致了一个活跃的研究社区,研究感知和场景解释问题,如车道检测。传统的车道检测方法依赖于专门的、手工定制的特征,速度慢,容易扩展。最近基于深度学习和像素车道分割的方法已经取得了更好的结果,并且能够推广到广泛的道路和天气条件。然而,由于车载平台上的资源有限,实用的算法必须在计算上便宜,同时又能准确地满足安全措施。该方法首先利用编码器-解码器深度学习架构生成车道二值分割图,然后对二值分割图进行进一步处理以分离车道,再利用滑动窗口提取每个车道生成车道实例分割图。该方法在多样本数据集上进行了验证,取得了较好的效果。

This paper proposes a new CAD tool that automates the RTL code generation based on the IPXACT standard (develop RTL code using XML files). Many related work generates RTL design using C language. In this work, the generation is based on XML descriptions. The tool is developed using Python. The generated RTL code can be synthesized by the synthesis tool like Design Compiler. Several commercial tools like MATLAB have this capability, but the proposed tool is faster and more configurable.

Accurate positioning is required to achieve accurate navigation solution of moving objects therefore, inertial navigation system (INS) and global positioning system (GPS) are combined together to give a good solution in solving positioning problem and overcoming the problem of using each system separately. The motivation behind this work in this paper is to model and evaluate an INS/GPS integration algorithm model within 6-DOF flight simulation model by using loosely coupled integration technique and extended kalman filter (EKF) Algorithms to enhance and solve the position and attitude angles problems. Then, it is implemented on embedded microcontroller system (TM4C123GH6PM ARM Cortex-M4) using low-cost commercial sensors (MPU-6050 and GPS). Finally, the Navigation model is evaluated within 6-DOF simulation model using Processor-in-Loop (PIL) method. The system can realize comparable navigation accuracy with other high performance navigation system.
为了实现运动目标的精确导航,需要进行精确定位,因此将惯性导航系统(INS)和全球定位系统(GPS)结合起来,很好地解决了定位问题,克服了各自单独使用的问题。本文的工作动机是利用松耦合积分技术和扩展卡尔曼滤波(EKF)算法对六自由度飞行仿真模型中的INS/GPS集成算法模型进行建模和评估,以增强和解决位置和姿态角问题。然后,利用低成本的商用传感器(MPU-6050和GPS)在嵌入式微控制器系统(TM4C123GH6PM ARM Cortex-M4)上实现。最后,利用环内处理器(PIL)方法在六自由度仿真模型中对导航模型进行了评估。该系统可实现与其他高性能导航系统相当的导航精度。

The generation of Multi-scroll chaotic attractors and chaos theory has gained much attention due to its many usages in a wide range of applications such as image-encryption and random number generators. There have been many previous attempts to establish a system that is able to generate large numbers of n − scroll chaotic attractors by modifying existing systems such as Lorenz and Chua’s systems. In this paper, a proposed system based on generalizing Chua’s system that has shown its ability to produce an unprecedentedly large number of even and odd chaotic scrolls is introduced. MATLAB simulation is carried out to validate the proposed system and a GUI tool was developed to ease the process of generating any number of chaotic scrolls. Finally, an insight on how the proposed system can be generalized on the circuits level is given.

We adopt retransmissions-upon-decoding-errors in a slotted-Aloha system, and account for the temporal interference correlation. We study the impact of the content-dependent access probabilities on the overall performance of the network. We verify the analytical results of this work via intensive Monte-Carlo simulations.

Improved Semantic Segmentation of Low-Resolution 3D Point Clouds Using Supervised Domain Adaptation 基于监督域自适应的低分辨率三维点云改进语义分割

One of the key challenges in applying deep learning to solve real-life problems is the lack of large annotated datasets. Furthermore, for a deep learning model to perform well on the test set, all samples in the training and test sets should be independent and identically distributed (i.i.d.), which means that test samples should be similar to the samples that were used to train the model. In many cases, however, the underlying training and test set distributions are different. In such cases, it is common to adapt the test samples by transforming them to their equivalent counterparts in the domain of the training data before being processed by the deep learning model. In this paper, we perform domain adaptation of low-resolution 8, 16 and 32 channels LiDAR 3D point clouds projected on 2D spherical images in order to improve the quality of semantic segmentation tasks. To achieve this, the low-resolution 3D point clouds are transformed using an end-to-end supervised learning approach to spherical images that are very similar to those obtained by projecting high-resolution 64 channels LiDAR point clouds, without changing the underlying structure of the scene. The proposed framework is evaluated by training a semantic segmentation model on 64 channels LiDAR clouds from the Semantic KITTI dataset [1] and using this model to segment 8, 16 and 32 channel point clouds after adapting them using our framework. The results obtained from carried out experiments demonstrate the effectiveness of our framework where segmentation results surpassed those obtained with nearest neighbor interpolation methods.
将深度学习应用于解决现实问题的关键挑战之一是缺乏大型注释数据集。此外,为了使深度学习模型在测试集上表现良好,训练集和测试集中的所有样本都应该是独立且同分布的(i.i.d),这意味着测试样本应该与用于训练模型的样本相似。然而,在许多情况下,底层的训练集和测试集分布是不同的。在这种情况下,在深度学习模型处理之前,通常通过将测试样本转换为训练数据域中的等效对应来调整测试样本。在本文中,为了提高语义分割任务的质量,我们对投射在二维球面图像上的低分辨率8、16和32通道LiDAR 3D点云进行了域适应。为了实现这一目标,使用端到端监督学习方法将低分辨率3D点云转换为球形图像,这些图像与投影高分辨率64通道LiDAR点云获得的图像非常相似,而不改变场景的底层结构。通过对来自semantic KITTI数据集[1]的64通道LiDAR云进行语义分割模型训练,并使用该模型对使用我们的框架进行调整后的8、16和32通道点云进行分割,对所提出的框架进行了评估。实验结果证明了该框架的有效性,分割结果优于最近邻插值方法。

Three Dimension Angular Position Stabilization using LQR and Kalman Filter 基于LQR和卡尔曼滤波的三维角位置稳定

This paper presents a design and evaluation for controlling a coupled system using a robust Linear Quadratic Regulator (LQR) controller acting on the augmented integral state space matrix model of a coupled system. System under investigation consisted of dual fan module that is interlinked and its axis moving freely in the pitch plan. On the other hand, a counter weight was used to balance the two fans thrust to optimize the controller effort in the elevation plan. The counterweight axe was denoted as the elevation axis. If the fans are not on the same horizontal line, the rotation of the system around itself in clockwise or anti-clockwise direction was carried out around the travel axis. The LQR controller design parameters should be able to stabilize itself at any degree on the travel or elevation axes while maintaining hover level along the pitch axis. Such controller acts by defining the penalty of each type of error in controlling this system. The error was multiplied by relevant penalty, then fed-back to the controller that controls the fan speeds accordingly.

本文提出了一种基于耦合系统增广积分状态空间矩阵模型的鲁棒线性二次调节器(LQR)控制器的设计与评价方法。所研究的系统由双风扇模块组成,该风扇模块相互连接,其轴在俯仰平面上自由移动。另一方面,利用配重平衡两个风机的推力,优化控制器在俯仰平面上的工作。配重斧用标高轴表示。如果风机不在同一水平线上,则系统围绕自身沿行程轴进行顺时针或逆时针方向的旋转。LQR控制器设计参数应该能够在沿俯仰轴保持悬停水平的同时,在行程轴或仰角轴上任意程度地稳定自身。这种控制器的作用是定义控制系统时每种错误的惩罚。误差乘以相应的惩罚,然后反馈给相应控制风扇速度的控制器。表示模型有三个轴,每个轴都有比例、导数和积分项,用于行程轴和高程轴,但不包括俯仰轴,其原因将在稍后的文章中讨论。建模从设计过程开始,首先定义系统的非线性模型,对其进行线性化,然后将其转换为状态空间格式,在模型中加入积分部分,最后设计并测试LQR控制器。

Named Entity Recognition (NER) is an important task in many natural language processing applications. There are several studies that have focused on NER for the English language. However, there are some limitations when applying the current methodologies directly on the Arabic language text. Recent studies have shown the effectiveness of pooled contextual embedding representations and significant improvements in English NER tasks. This work investigates the performance of pooled contextual embeddings and bidirectional encoder representations from Transformers (BERT) model when used for NER on the Arabic language while addressing Arabic specific issues. The proposed method is an end-to-end deep learning model that utilizes a combination of pre-trained word embeddings, pooled contextual embeddings, and BERT model. Embeddings are then fed into bidirectional long-short term memory networks with a conditional random field. Different types of classical and contextual embeddings were experimented to pool for the best model. The proposed method achieves an F1 score of 77.62% on the AQMAR dataset, outperforming all previously published results of deep learning, and non-deep learning models on the same dataset. The presented results also surpass those of the wining system for the same task on the same data in the Topcoder website competition.
命名实体识别(NER)是许多自然语言处理应用中的一项重要任务。有几项研究集中在英语的NER上。但是,在将目前的方法直接应用于阿拉伯文文本时存在一些限制。最近的研究表明了集合上下文嵌入表示的有效性,并显著改善了英语NER任务。这项工作研究了在解决阿拉伯语特定问题的同时,将变形器(BERT)模型的混合上下文嵌入和双向编码器表示用于阿拉伯语的NER时的性能。提出的方法是一种端到端深度学习模型,该模型结合了预训练词嵌入、池上下文嵌入和BERT模型。然后将嵌入输入到具有条件随机场的双向长短期记忆网络中。对不同类型的经典嵌入和上下文嵌入进行了实验,以获得最佳模型。该方法在AQMAR数据集上取得了77.62%的F1分数,优于之前发表的所有深度学习和非深度学习模型在同一数据集上的结果。所提出的结果也超过了Topcoder网站比赛中相同数据上相同任务的获奖系统。
