Assessing Air Traffic Management Performance Interdependencies through Bayesian Networks： Preliminary Applications and Results

The performance model proposed by this study represents an innovative approach to deal with performance assessment in ATM （air traffic management）. It is based on Bayesian networks methodology, which presents several advantages but also some drawbacks as highlighted along the paper. We illustrate the main steps required for building the model and present a number of interesting results. The contribution of the paper is two-fold： （1） It presents a new methodological approach to deal with a problem which is of strategic importance for ANSPs （air navigation service providers）; （2） It provides insights on the interdependencies between factors influencing performance. Both results are considered particularly important nowadays, due to the SES （Single European Sky） performance scheme and its related target setting process.

Traffic Characteristics Based Dynamic Radio Resource Management in Heterogeneous Wireless Networks

The traffic with tidal phenomenon in Heterogeneous Wireless Networks(HWNs)has radically increased the complexity of radio resource management and its performance analysis.In this paper,a Simplified Dynamic Hierarchy Resource Management(SDHRM)algorithm exploiting the resources dynamically and intelligently is proposed with the consideration of tidal traffic.In network-level resource allocation,the proposed algorithm first adopts wavelet neural network to forecast the traffic of each sub-area and then allocates the resources to those sub-areas to maximise the network utility.In connection-level network selection,based on the above resource allocation and the pre-defined QoS requirement,three typical network selection policies are provided to assign traffic flow to the most appropriate network.Furthermore,based on multidimensional Markov model,we analyse the performance of SDHRM in HWNs with heavy tailed traffic.Numerical results show that our theoretical values coincide with the simulation results and the SDHRM can improve the resource utilization.

A Novel Outage Capacity Objective Function for Optimal Performance Monitoring and Predictive Fault Detection in Hybrid Free-Space Optical and RF Wireless Networks

This study develops an optimal performance monitoring metric for a hybrid free space optical and radio wireless network, the Outage Capacity Objective Function. The objective function—the dependence of hybrid channel outage capacity upon the error rate, jointly quantifies the effects of atmospheric optical impairments on the performance of the free space optical segment as well as the effect of RF channel impairments on the radio frequency segment. The objective function is developed from the basic information-theoretic capacity of the optical and radio channels using the gamma-gamma model for optical fading and Ricean statistics for the radio channel fading. A simulation is performed by using the hybrid network. The objective function is shown to provide significantly improved sensitivity to degrading performance trends and supports of proactive link failure prediction and mitigation when compared to current thresholding techniques for signal quality metrics.

Reinforcement Learning-Based Optimization for Drone Mobility in 5G and Beyond Ultra-Dense Networks

Drone applications in 5th generation(5G)networks mainly focus on services and use cases such as providing connectivity during crowded events,human-instigated disasters,unmanned aerial vehicle traffic management,internet of things in the sky,and situation awareness.4G and 5G cellular networks face various challenges to ensure dynamic control and safe mobility of the drone when it is tasked with delivering these services.The drone can fly in three-dimensional space.The drone connectivity can suffer from increased handover cost due to several reasons,including variations in the received signal strength indicator,co-channel interference offered to the drone by neighboring cells,and abrupt drop in lobe edge signals due to antenna nulls.The baseline greedy handover algorithm only ensures the strongest connection between the drone and small cells so that the drone may experience several handovers.Intended for fast environment learning,machine learning techniques such as Q-learning help the drone fly with minimum handover cost along with robust connectivity.In this study,we propose a Q-learning-based approach evaluated in three different scenarios.The handover decision is optimized gradually using Q-learning to provide efficient mobility support with high data rate in time-sensitive applications,tactile internet,and haptics communication.Simulation results demonstrate that the proposed algorithm can effectively minimize the handover cost in a learning environment.This work presents a notable contribution to determine the optimal route of drones for researchers who are exploring UAV use cases in cellular networks where a large testing site comprised of several cells with multiple UAVs is under consideration.

Multi-indicator Active Queue Management Method

A considerable number of applications are running over IP networks.This increased the contention on the network resource,which ultimately results in congestion.Active queue management(AQM)aims to reduce the serious consequences of network congestion in the router buffer and its negative effects on network performance.AQM methods implement different techniques in accordance with congestion indicators,such as queue length and average queue length.The performance of the network is evaluated using delay,loss,and throughput.The gap between congestion indicators and network performance measurements leads to the decline in network performance.In this study,delay and loss predictions are used as congestion indicators in a novel stochastic approach for AQM.The proposed method estimates the congestion in the router buffer and then uses the indicators to calculate the dropping probability,which is responsible for managing the router buffer.The experimental results,based on two sets of experiments,have shown that the proposed method outperformed the existing benchmark algorithms including RED,ERED and BLUE algorithms.For instance,in the first experiment,the proposed method resides in the third-place in terms of delay when compared to the benchmark algorithms.In addition,the proposed method outperformed the benchmark algorithms in terms of packet loss,packet dropping,and packet retransmission.Overall,the proposed method outperformed the benchmark algorithms because it preserves packet loss while maintaining reasonable queuing delay.

Managing and Measuring Business Networks in Russia

The research topic of this article ＂Managing and measuring business networks in Russia＂ has been under consideration in three successive research projects oriented to Russian business to business （B2B） networks. The projects have been accomplished by HAMK, VTT Technical Research Centre of Finland, and Tampere University of Technology （TUT）. Russian experts from The Higher School of Economics in Moscow and the Graduate School of Management in St. Petersburg were involved in these projects. We asked how managing and measuring B2B networks should be developed, when a company becomes established to Russian market. Both qualitative and quantitative analytical methods were used. Results concerning performance measurement presented in this article are based on data which was collected using survey and a questionnaire. Methodical triangulation was carried out as both research instruments produced 17 full answers for questions concerning performance measurement. Wider results are based on about 200 face-to-face interviews and answers for questionnaires. Results indicate that in Russia the management and leadership models as well as the company performance measurement should be adjusted to Russian traditions. Networked companies have difficulties in applying matrix type organizations in Russia, as management practices are based traditionally on authoritarian leadership. However, clear and specific targets should be set for projects and strategic business areas. Targets and bonuses should be agreed on with managers and staff throughout the company and the business network. Personal networks, within project stake- holders, have more emphasis in Russia than in Finland, because personal relations to authorities＇, and organizations are needed at every stage of the project. Therefore, managing SMEs working in B2B networks is challenging in Russia. In this article, a method for setting and implementing strategic targets for a business networked company is presented. Understanding networked performance measurement indicators will enable successful business for all networked partners in the long tenn.

元宇宙“人身侵害”刑法应对的反思与修正

元宇宙在带来新的发展机遇与互动方式的同时,也潜藏着“人身侵害”的风险。元宇宙有限沉浸性所引发的深度冒犯是刑法介入元宇宙“人身侵害”的法理依据,社会控制理论、社会学习理论则为刑法介入提供了犯罪学上的理由。“个人—支配犯”的应对模式在解释论上无法成立,元宇宙“人身侵害”不符合绝大多数侵犯公民人身权利犯罪的构成要件,且因匿名性带来的认识错误问题进一步限缩了此类犯罪的适用空间。以义务犯理论为基础并考虑到平台履行积极义务的优势,应以“平台—义务犯”作为元宇宙“人身侵害”的刑法应对模式,从义务类型、功能需求、行刑衔接三个方面对拒不履行信息网络安全管理义务罪作解释论上的限制,同时充分发挥软法的引导功能与行政法的管控功能,使拒不履行信息网络安全管理义务罪居于“备而慎用”的状态,以实现对元宇宙“人身侵害”的合理规制。

协同创新网络视角下装备制造企业创新绩效影响研究

随着技术复杂性的日益提升,装备制造业产业链不断优化升级,仅依靠企业单打独斗难以实现创新,必须将企业置于协同创新网络中,与协作企业、大学和科研院所、政府、金融机构等多主体一起协同发展。因此,以协同创新网络为视角,探究装备制造企业创新绩效的影响因素。将知识管理作为中介,探究协同创新、知识管理以及创新绩效之间的关系,参考相关文献,构建三者之间的假设关系。运用SPSS26.0及AMOS23.0软件进行信效度分析,运用结构方程模型验证关系假设。结果表明,协同创新网络规模、协同创新网络关系强度、网络开放性、知识管理均对创新绩效有显著正向影响,同时知识管理也可作为中介效应,协同创新通过知识管理对创新绩效产生正向影响。

网络中介服务的刑事归责:边界划定与罪名诠义

网络中介服务提供者不履行安全管理义务导致严重后果的,应在不作为共犯的路径上探寻承担刑事责任的可行性。网络中介服务者在客观上违反法律、法规或行业准则为他人的犯罪行为提供了帮助,主观上具有帮助他人实施犯罪的目的,或是直接针对具有犯罪性质的软件、网页或功能提供技术服务,可判定逾越了中立帮助的界限;若客观上无明显异常,则要看主观上与正犯之间有无“通谋”。网络中介服务者对网络空间犯罪活动的不作为参与,未经责令改正而拒不改正的过程,通常不能以犯罪论处,但与正犯就不履行安全管理义务具有提供服务前的明知或提供服务后的通谋的,可直接成立相关犯罪的不作为犯。网络中介服务者积极参与的帮助,看其是否与正犯具有指向一致的犯罪故意内容,再决定是以帮助信息网络犯罪活动罪还是正犯所为之罪的共犯论处。
