Nowadays, one of the keys for the success of ICT technologies, in particular in the e-Health realm, is “Usability”. Self-assessment questionnaires are the most diffuse procedure for its evaluation. However, this procedure presents various limitations (e.g., subjectivity, needs of expert supervisors, etc.). In this paper, a methodology based on emotion recognition, web analytics and gaze detection is developed in order to asses usability of e-Health web platforms objectively, automatically, remotely and in the wild.
如今,信息通信技术成功的关键之一,特别是在电子卫生领域,是“可用性”。自评问卷是最分散的评估程序。然而,这一程序存在各种局限性(例如,主观性,专家监督者的需求等)。本文开发了一种基于情感识别、网络分析和凝视检测的方法,以客观、自动、远程和野外评估电子健康网络平台的可用性。

Modern vehicles are equipped with the different systems that help driver in the driving process ensuring safer and more comfortable driving. These systems are called Advanced Driver Assistance Systems (ADAS) and are step toward fully autonomous driving. The integral part of autonomous driving is an object detection and tracking by using front view camera which provides necessary information for emergency braking, collision avoidance, path planning, etc. In this paper, one possible approach to object detection and tracking in autonomous driving is presented. Two object detection methods are implemented and tested: Viola-Jones algorithm and YOLOv3. The Viola-Jones algorithm is used to create object detectors which detections are tracked in a video sequence. Nine object detectors were trained and they are divided into four groups (vehicle detectors, pedestrian detector, traffic light detector and traffic sign detectors). In second case, the YOLOv3 model was used for object detection. Both methods are evaluated in terms of accuracy and processing speed. For the purpose of object tracking, Median Flow tracking method and correlation tracking method are implemented and evaluated.
现代车辆配备了不同的系统,以帮助驾驶员在驾驶过程中确保更安全,更舒适的驾驶。这些系统被称为高级驾驶辅助系统(ADAS),是迈向全自动驾驶的一步。自动驾驶的重要组成部分是利用前视摄像头对目标进行检测和跟踪,为紧急制动、避碰、路径规划等提供必要的信息。本文提出了一种自动驾驶中目标检测与跟踪的可能方法。实现并测试了两种目标检测方法:Viola-Jones算法和YOLOv3。维奥拉-琼斯算法用于创建目标检测器,其检测在视频序列中被跟踪。训练了9个目标检测器,将其分为4组(车辆检测器、行人检测器、交通灯检测器和交通标志检测器)。在第二种情况下,使用YOLOv3模型进行目标检测。两种方法在精度和处理速度方面进行了评估。以目标跟踪为目的,实现了中值流跟踪方法和相关跟踪方法,并对其进行了评价。

In this paper, an algorithm for autonomous vehicle trajectory planning is proposed. The proposed algorithm consists of two parts. In the first part, transformation of given coordinates from Cartesian system to Frenet-Serret system is applied, along with interpolation of points in trajectory. In the second part, most efficient trajectory is being chosen and optimized. The algorithm was developed in Udacity’s simulator, where it was tested and compared with other similar algorithms. The algorithm shows promising performance through testing.

Nowadays, we are trying to achieve as much vehicle autonomy as possible by developing Advanced Driver-Assistance Systems (ADAS). For such a system to make decisions, it should have insight into the environment of the vehicle, e.g. the objects surrounding the vehicle. During forward driving, the information about the objects in front of the vehicle is usually obtained by a front view in-vehicle camera. This paper describes the image classification method of the objects in the front of the vehicle based on deep convolutional neural networks (CNN). Such CNN is supposed to be implemented in embedded system of an autonomous vehicle and the inference should satisfy real-time constraints. This means that the CNN should be structured to have fast inference by reducing the number of operations as much as possible, but still having satisfying accuracy. This can be achieved by reducing the number of parameters which also means that the resulting network has lower memory requirements. This paper describes the process of realizing such a network, from image dataset development up to the CNN structuring and training. The proposed CNN is compared to the state-of-the-art deep neural network in terms of classification accuracy, inference speed and memory requirements.
如今,我们正试图通过开发高级驾驶辅助系统(ADAS)来实现尽可能多的车辆自动驾驶。为了让这样的系统做出决策,它应该能够洞察车辆的环境,例如车辆周围的物体。在前向驾驶过程中,车辆前方物体的信息通常由前视车载摄像头获取。本文描述了一种基于深度卷积神经网络(CNN)的车辆前方物体图像分类方法。这种CNN是在自动驾驶汽车的嵌入式系统中实现的,其推理需要满足实时性约束。这意味着CNN的结构应该通过尽可能减少操作数量来实现快速推理,但仍然具有令人满意的准确性。这可以通过减少参数的数量来实现,这也意味着最终的网络具有更低的内存需求。本文描述了实现这种网络的过程,从图像数据集的开发到CNN的构建和训练。在分类精度、推理速度和内存要求方面,将所提出的CNN与最先进的深度神经网络进行了比较。

In this paper, a system which enables testing and faster development in automotive industry is proposed. The system enables testing in a very simple way, allowing for cost savings during testing and development, as well as raising security in a way that first tests are not to be performed on real roads, but are done in the laboratory. Automotive Machine Vision Grabber is a device whose purpose is capturing multiple video streams and saving them to hard disk drive. Captured streams could then be used for testing various ADAS algorithms used in automotive. This paper shows implementation of FPGA design, camera control system and PCIe interface. Furthermore, different tests were performed, while the obtained results are promising.

With the progress of automotive industry arose a need for development of fully autonomous vehicles. Such vehicle is equipped with sensors and cameras designed for monitoring its surroundings. Data received from these sensors is then processed in the vehicle’s embedded system which contains algorithms that help driver in a driving process and are a step towards a fully autonomous vehicle. Due to the problem complexity, these algorithms are usually based on machine learning methods and thus inherently require large amounts of data for successful training. Data used for training is mostly video content of situations from actual traffic. To record that video content specialized hardware and its accompanying software is needed. This paper focuses on developing software for existing AMV Grabber hardware board. Entire software stack was developed, from low-level application which controls the hardware directly, through device driver which enables communication between the board and PC, to PC application which enables users to control the hardware indirectly, i.e., to send commands to the board to start or stop recording. PC application is also used to receive data from the board and store it on non-volatile memory of the PC. Finally, measurements were done to display overall system performance.

Tracking of attendance is a ubiquitous task in many institutions and during organised events. This, along with subsequent management of collected data can be a cumbersome activity that requires significant time and effort, from all involved parties. Tracking and managing student attendance during lectures and exams is an especially important instance of that task. Automated attendance management systems devised in the literature differ in applied technological solutions and features. However, many of these lack some features that would make them particularly useful for the task of student attendance management. This paper proposes the design of an automatic system tailored for the tracking and management of student attendance data. The design incorporates three main components that interact to deliver a seamless user experience. The key element is the utilisation of simple beacons, which make the system cost-effective and easy to use. Combining them with a mobile platform and a web service enables versatile attendance tracking. Periodic detection of the nearby beacons with authenticated server-side logic makes the proposed design unique in terms of addressing common attendance tracking issues. Also, the design is open for future integration of sophisticated data analysis modules.
在许多机构和有组织的活动中,跟踪考勤是一项无处不在的任务。这以及随后对收集数据的管理可能是一项繁琐的活动,需要所有相关方投入大量时间和精力。跟踪和管理学生在上课和考试期间的出勤率是这项任务的一个特别重要的例子。文献中设计的自动考勤管理系统在应用技术解决方案和功能上有所不同。然而,其中许多缺乏一些功能,这些功能将使它们对学生出勤管理任务特别有用。本文提出了一种针对学生考勤数据跟踪与管理的自动化系统的设计。该设计包含三个主要组件,它们相互作用,提供无缝的用户体验。关键因素是使用简单的信标,这使得系统具有成本效益和易于使用。将它们与移动平台和web服务相结合,可以实现多功能的考勤跟踪。使用经过身份验证的服务器端逻辑对附近信标进行周期性检测,这使得所建议的设计在解决常见的考勤跟踪问题方面是独一无二的。此外,该设计对将来集成复杂的数据分析模块是开放的。

This paper describes the field trials carried out in the Bucharest region in Romania for testing and analyzing the performance of the second generation of the Digital Video Broadcasting Terrestrial standard using the base profile for portable indoor reception. Test results are presented for the terrestrial broadcasted public programs of the Romanian National Television. The results consist of the values of the Carrier to Noise ratio, Modulation Error Rate and Link Margin in different geographical locations and receiving conditions. These values can update those provided by previous studies and provide planning tools for the Digital Terrestrial Television implementation using the second generation of the Digital Video Broadcasting Terrestrial standard. The results proved that the portable indoor reception in the Bucharest region for the Romanian National Television programs is possible, and this may be used to improve the end user experience with an additional television service to the existing cable or satellite television, since the digital terrestrial television has the advantage of mobility reception.

The accelerated development of the IT sector has been reconfiguring the labour market by creating new jobs and by changing work environments. It has linked people from all continents, allowing them to communicate easily within a virtual world. Even though IT has brought obvious benefits, it has also brought some serious challenges related to employee wellbeing. In the last few years, we have faced some serious problems that emerged as a consequence of mismanaged technological interventions. They have led to blurring the line between work and private life. Employee availability has made never-ending workdays a fact of life. Some new work stressors, such as technostress and workplace cyberbullying, have emerged. Solving these problems is a momentous challenge for experts from various scientific fields. The scientific endeavours have to point to the ways in which technology could be brought back to the role of improving work performance in a way that would enhance human wellbeing and make employees enthusiastic about their future in the digital age.
IT业的加速发展创造了新的就业机会,改变了工作环境,从而重新配置了劳动力市场。它将来自各大洲的人们联系在一起,使他们能够在虚拟世界中轻松交流。尽管IT带来了明显的好处,但它也带来了一些与员工福利相关的严重挑战。在过去的几年里,由于技术干预管理不善,我们面临着一些严重的问题。它们模糊了工作和私人生活之间的界限。员工的可用性已经让没完没了的工作日成为一种生活常态。一些新的工作压力源已经出现,比如技术压力和职场网络欺凌。解决这些问题对各个科学领域的专家来说是一个重大挑战。科学努力必须指出,如何让技术重新发挥改善工作绩效的作用,从而增进人类福祉,并让员工对自己在数字时代的未来充满热情。
