The widespread of Internet technologies highlights one important issue. The problem is related to security and safety of our data. Traditional logins and passwords are not efficient enough and cannot guarantee expected security level. Motivated by that we present an approach to utilize haptics device (stimuli generator) within biometrics-based security procedure. The combination of these elements is based on generation of divergent stimuli and observation of the human reaction that is measured with different liveliness parameters as heart rate, emotions from the face (valence and arousal) as well as hand movements. Right now, our analysis is rather theoretical as we are still in the process of data collection. Finally, we outline further steps in the research as well as recent conclusions.
互联网技术的广泛应用凸显了一个重要问题。这个问题与我们数据的安全性有关。传统的登录和密码不够有效,不能保证预期的安全级别。基于此,我们提出了一种在基于生物识别的安全程序中使用触觉设备(刺激发生器)的方法。这些元素的组合是基于不同刺激的产生和对人类反应的观察,这些反应是通过心率、面部情绪(效价和唤醒)以及手部运动等不同的活力参数来测量的。目前,我们的分析还是比较理论化的,因为我们还在数据收集的过程中。最后,我们概述了进一步的研究步骤以及最近的结论。

The carrying capacity of water resources and the environment has become a restrictive factor in economic development. It is also of great significance to Xi’an City, which is rapidly developing and lacking water. Based on the carrying capacity of water resources and environment, we construct an evaluation index system in four aspects: water resources, water environment, society, and economy. The entropy weight method is used to objectively give weights along with the TOPSIS method and the fuzzy comprehensive evaluation method to evaluate the method for the period from 2006 to 2020. The carrying capacity of water resources and the environment in Xi’an City, and its restrictive factors are explored with the obstacle degree model. In general, from 2006 to 2020, the carrying capacity of water resources and the environment in Xi’an showed a fluctuating upward trend. From the perspective of each subsystem, the comprehensive score of each subsystem showed an upward trend. From the perspective of obstacles, the water resources in Xi’an were restricted. The obstacles to environmental carrying capacity mainly came from water resources and water environment subsystems.
水资源和环境的承载能力已成为制约经济发展的因素。这对快速发展的缺水城市西安市也具有重要意义。以水资源和环境承载力为基础,从水资源、水环境、社会和经济四个方面构建了评价指标体系。采用熵权法、TOPSIS法和模糊综合评价法对2006 - 2020年的方法进行客观赋权。运用障碍度模型对西安市水资源环境承载力及其制约因素进行了探讨。总体而言,2006 - 2020年西安市水资源环境承载力呈波动上升趋势。从各分系统来看,各分系统的综合得分均呈上升趋势。从障碍的角度看,西安市水资源受到制约。环境承载力的障碍主要来自水资源和水环境子系统。

The automatic judgment of the object’s angle can enhance the work efficiency of mechanical loading and unloading, which is necessary for the workflow of non-fixed placement. Therefore, we develop a method for judging object angles that can be imported into various scenarios. First of all, the model of each tool is established. Before the identification process, the proposed system improves the accuracy by adjusting the brightness and contrast. Then, the position and angle of the object are judged to command the robotic arm for gripping. In addition, the best gripping point is found according to the boundary shape of the object to enhance the stability of the moving process so that the workpiece does not fall during the process. The object’s coordinates, angle, and clamping position are determined after the images are captured through the camera to improve the efficiency of the handling process. This design can be implemented in various loading and unloading processes.

Nowadays, The SF6 circuit breaker is an indispensable critical protective device in the UHV power transmission network. In order to study the arc characteristics more accurately, a nozzle arc model is established based on mesoscopic lattice Boltzmann method. Based on this model, the arc process of SF6 circuit breaker is simulated. This paper analyzes the temperature change in 50$mu$s before and after zerocrossing current. The high-temperature particles mainly gather at the front end of the static contact, where the risk of thermal breakdown is greater. The distribution of temperature, density, and gas velocity on the arc core shows the cause of this hightemperature region.

In this project, we develop a device to warn the elderly when they are unsteady and at a risk of falling, based on a low price IMU sensor. From our preliminary study we find that during the sway, the body vibrates violently in all frequencies. This is different from the body at stationary posture, where the vibration is small, or when a person moves in a regular manner where the body vibrates with some definite frequencies. From these results, it is possible to use the mean amplitude of the Fourier spectrum of the body acceleration to distinguish the vibration state of the body, which can be used in the warning system. We then designed the device using the low price MPU6050 sensor to measure the body acceleration. This device will be attached to the body (hip) for collecting the acceleration data. An ESP8266 board is used to collect and control the sensor operation. Another ESP8266 board is used to receive and send the data to a Raspberry Pi unit. All data transmission is performed wirelessly via ESP NOW protocol, which is a low power consumption 2.4GHz wireless communication with a data package of up to 250 bytes at a time with 100-200m transmission range, which cover the living space area of typical wearer. When the mean amplitude of Fourier spectrum is greater than the warning criteria, the Raspberry Pi will send a signal to the warning unit wirelessly through the ESP8266 board. There are 3 types of alarms in warning unit which are sound alarm, light alarm, and LCD display alarm. We have tested our system with many volunteers. The mean amplitude of Fourier spectrum in the steady, walking, and sway condition can be clearly distinguished. In all cases the state of risky from falling can be detected correctly. We are now in the process of maximizing the data sampling and analyzing time to make the falling prediction as fast as possible.
在这个项目中,我们开发了一种基于价格低廉的IMU传感器的装置,可以在老年人不稳定和有跌倒风险时发出警报。从我们的初步研究中我们发现,在摇摆期间,身体在所有频率上剧烈振动。这与静止的身体不同,静止的身体振动很小,或者当一个人以一种有规律的方式运动时,身体会以一定的频率振动。从这些结果可以看出,利用物体加速度傅立叶谱的平均幅值来区分物体的振动状态,可用于预警系统。然后,我们设计了使用低价格的MPU6050传感器来测量人体加速度的设备。该装置将连接到身体(臀部)收集加速度数据。ESP8266板用于采集和控制传感器的运行。另一块ESP8266板用于接收和发送数据到树莓派设备。所有数据传输均通过ESP NOW协议进行无线传输,这是一种低功耗的2.4GHz无线通信,每次数据包最大可达250字节,传输范围为100-200m,覆盖了典型佩戴者的生活空间区域。当傅里叶频谱的平均幅度大于预警标准时,树莓派将通过ESP8266板向预警单元无线发送信号。报警单元有声音报警、光报警、液晶显示报警三种报警方式。我们已经让许多志愿者测试了我们的系统。在稳定、行走和摇摆状态下,傅里叶谱的平均振幅可以被清楚地区分出来。在所有情况下,都可以正确地检测到危险状态。我们现在正处于最大化数据采样和分析时间的过程中,以使下降预测尽可能快。

In order to improve the efficiency and accuracy of human resource management by big data technology, support vector machines are used to complete job matching. The element sample for the employee indicator is sparsely represented to obtain the matrix. The sample is binary classification by a support vector machine to judge the matching degree of employees to positions. Finally, the random transformation function is introduced to achieve dynamic recommendations in the big data environment. The experimental results show that the algorithm has high job matching accuracy, high dynamic recommendation efficiency, and batch recommendation.

The emergence of the Internet of Vehicles will transform how various road users interact with one another. The safety of road users, such as cyclists, may be enhanced by the real-time traffic data gathered by the on-road sensors and autonomous vehicles. To communicate with vehicles or pedestrians, cyclists still use physical indications like head movements and hand gestures at the moment rather than taking advantage of the Internet of Vehicles and sensors. We outline research that uses multimodel interaction to improve bike traffic safety. To enhance traffic information awareness and increase bike safety, we deploy user interaction with head-mounted displays and wearable haptic displays for cyclists. We propose the detailed system architecture design and traffic event alerts provided by haptic and augmented reality visual interaction in various traffic scenarios. Initial user feedbacks suggest the positive potential to enhance the cyclists′ safety and further improve directions.

With the continuous development of the traffic industry, the continuing education of the drivers also urgently needs to be improved under the background of epidemic normalization. In order to improve the manager′s learning status of the online training of employees, we designed a traffic safety education system based on real-time facial recognition. First of all, high-precision face recognition is achieved through a lightweight face recognition network. Head posture is estimated based on the 3D rotation of the face. When the set threshold value is reached, the warning “Please drive carefully” pops up to ensure the learning effect of drivers and help managers avoid the loss and risk of traffic accidents caused by drivers′ weak safety awareness.

The sharing of meteorological message transmission of information in satellite communication was researched. It was found that the meteorological message information collected by satellite communication equipment was 100 characters, while the transmission capacity was 158 characters. The content of the information sent by each meteorological observation station was at most one and a half of meteorological message information. Each observation station received all the information sent by other stations and the relationship expression between the number of stations. Thus, the minimum propagation time was obtained, and the corresponding information transmission aggregation model was established. According to the transmission of the specified station, the rules were found, and the information of other stations received by each station in each round was obtained. The transmission scheme of the meteorological message of the master station was as follows. The first round adopted closedloop sequential transmission, that is $2rightarrow 1,3 rightarrow 2,ldots, 1rightarrow$ n, while from the second round, each round adopted the mode of transmission from the i+2 station to the i station ($i leq n-2$). The mode 1$rightarrow$n-1,2$rightarrow$n was adopted by the first and second stations. Based on the result, a transmission model is established to find out the rule of station information sharing at a certain time. Finally, the number of stations N=9 was used to verify the feasibility of the propagation model.
研究了卫星通信中气象信息传输的共享问题。研究发现,卫星通信设备采集的气象电文信息为100个字符,而传输容量为158个字符。各气象观测站发送的信息内容最多为1.5条气象电文信息。每个观测站接收到其他观测站发送的全部信息以及观测站数之间的关系表达式。从而求得最小传播时间,并建立相应的信息传播聚合模型。根据指定台站的传输情况,找到规则,得到每轮各台站接收到的其他台站信息。主站气象电文的传输方案如下:第一轮采用闭环顺序传输,即$2rightarrow 1,3 rightarrow 2,ldots, 1rightarrow$ n,而从第二轮开始,每一轮采用从i+2站到i站($i leq n-2$)的传输方式。第一、二站采用1 $rightarrow$ n-1,2 $rightarrow$ n模式。在此基础上,建立了一个传输模型,找出某一时刻车站信息共享的规律。最后用台数N=9验证传播模型的可行性。

Recently, the clog in transportation is expected to get worse because of a new stage pandemic. It is expected that flights will be a tremendously increase in after the resuming. As a result, for improving efficiency of the airport and reducing the loss of delays in cost was bear in the author’s mind. Python is used in which software to indicate program code and calculated the optimized taxiways with Genetic Algorithm (GA) method. The database was created to facilitate calculation and layout of the optimized taxiway. In addition, an operational interface, which is for Air Traffic Control (ATC) to operate intuitively and give cleaver instructions, is made. Through the study can alleviate ATC workload and increase efficiency simultaneously. The data in this paper is based on the Taoyuan International Airport (TPE) of Taiwan for research.
最近,由于新一阶段的大流行,预计交通堵塞将更加严重。预计恢复后,航班将大幅增加。因此,为了提高机场的效率,减少延误的损失,在成本上是笔者所铭记的。采用Python软件编写程序代码,并采用遗传算法(Genetic Algorithm, GA)方法计算优化后的滑行道。为方便优化滑行道的计算和布局,建立了数据库。此外,还设计了一个操作界面,使空中交通管制(ATC)操作更直观,指令更清晰。通过研究可以减轻空管的工作量,同时提高效率。本文以台湾桃园国际机场(TPE)为研究对象。
