Technological development in every aspect of human life has formed a wider analytical approach to crime. The genesis and structure of crime, its intensity, and dynamics are subjects of intense scientific studies carried out by researchers in various fields of science. Increasing possibilities to track crime events give public organizations and police departments the opportunity to collect and store detailed data, including spatial and temporal information. At the same time, the crowd-sourced open datasets as social media and Internet datasets can be a valuable source of knowledge about various behavior patterns and social phenomena, including those of criminal nature. Thus, exploratory analysis and data mining become an important part of the current methodology for the detection and forecasting of crime development. The ability to use data analysis tools to extract useful information related to criminal events enables law enforcement agencies to more efficiently allocate their resources to specific crime areas. It allows the effective deployment of officers to high-risk crime areas and elimination from areas with a decreasing crime trend as well as developing effective crime prevention strategies. The purpose of this paper is to show the usefulness of analytic algorithms in predicting crimes, however, there are other applications of such analyzes in the area of law enforcement, such as defining criminal hot spots, creating criminal profiles, and detecting crime trends. The most important factor is the accuracy with which one can infer and create new knowledge based on observations from the past that will be useful in the process of reducing the number of crimes (predictive policing) and ensure the security of citizens.

In development of plausible commercial logistics ‘Unmanned Aircraft Systems’ (UAS) devices there is a need for the establishment of legislation as well as operational protocols. Aerial corridors for logistical UAS’s within city areas needs consideration of legal instruments and the guidance provided by the relevant government—industry bodies. There could be conflicts with business needs and wants to meet product and customer requirements. As such this paper suggest the use of ‘Systems Engineering Process’ (SEP) as a ‘method of operations’ (MO). The outcome desired is the use of logistical based UAS within a ‘Security containment box’ (SCB) to assist situation awareness; control and interdiction. An integral part of the ‘Concept of operations’ (CONOPS) is the use of ‘Integrated Corridor Management’ (ICM) and ‘Networked Expanded Ushering Shepherds’ (NEXUS) for real-time checking of compliance. A further feature is the meshing of the UAS ‘Aerial flight control system’ (AFCS) with the existing ‘Flight management system’ (FMS). The use of NEXUS is like having UAS licensed pilot(s) in a sharing economy based for logistical long-range deliveries. These pilots (Hosts) handover the approved UAS and flight paths via a human—‘Artificial Intelligence’ (AI) ‘Virtual flight management centre’ (VFMC) and the ‘Network Coordination Centre’ (NCC). All logistical delivery services actions; reactions and approvals are recorded via ‘Black box’ Blockchained (on UAS and Cloud) for each flight event with unique real-time referencing. This CONOPS utilises intermeshed Hosts; entities and architectural design of the aerial corridor using ‘4 dimensional Security containment box’ (4D–SCB). That is, a 4D–SCB (axis X, Y, Z and time) that requires a micro Radar network linked to AFCS—NCC.
在合理的商业物流“无人机系统”(UAS)设备的发展中，有必要建立立法以及操作协议。城市区域内后勤无人机的空中走廊需要考虑法律文书和相关政府-行业机构提供的指导。可能会与业务需求和满足产品和客户需求的愿望发生冲突。因此，本文建议使用“系统工程过程”(SEP)作为“操作方法”(MO)。期望的结果是在“安全遏制箱”(SCB)内使用基于后勤的无人机系统来协助情况感知;控制和封锁。“操作概念”(CONOPS)的一个组成部分是使用“综合走廊管理”(ICM)和“网络扩展引导员”(NEXUS)来实时检查合规性。另一个特点是无人机的“空中飞行控制系统”(AFCS)与现有的“飞行管理系统”(FMS)的啮合。使用NEXUS就像在共享经济中拥有无人机执照的飞行员，以进行物流远程交付。这些飞行员(主持人)通过人工“人工智能”(AI)“虚拟飞行管理中心”(VFMC)和“网络协调中心”(NCC)移交批准的无人机和飞行路径。所有物流配送服务行动;反应和批准通过“黑匣子”区块链(在无人机和云上)记录每个飞行事件，并提供唯一的实时参考。这个CONOPS利用互联主机;空中走廊的实体和建筑设计采用了“四维安全遏制箱”(4D-SCB)。也就是说，需要连接到AFCS-NCC的微型雷达网络的4D-SCB (X, Y, Z轴和时间)。

We report on the development of an Agent Based Model of a train derailment incident, considering a number of factors including friction and flange angle. We describe the background and objectives, and use the Rushall derailment as a Case Study. We use the NetLogo modeling environment to build our model. We describe the workings of the model. Two scenarios involving frequency of maintenance are tested using the model. We observe unexpected (emergent) results in one case.

The aim of the paper is to show how dynamic optimization techniques could be used in creating System Dynamics models. There are two possible applications of optimization in the context of System Dynamics methodology. The first application concerns the calibration of System Dynamics models - one can introduce computational technique which is the extension of the Gauss-Newton for the calibration of models described by algebraic equations. The second application is related to the problem of creating proper decision rules which usually are present in System Dynamics models. In that case we substitute original decision rules by control variables and then define an optimal control problem whose performance index is used to verify the effectiveness of a particular decision rule. Having the solution of the optimal control problem we use it to modify the decision rule or its parameters. We show the application of the proposed approach to System Dynamics models describing criminal activities: one model is related to drugs prevalence, the other one is based on relations known from epidemics models and can be treated as a generic model which can be used to describe various criminal activities.

Energy emulator is a specific t ype o f p ower electronic system to mimic the electrical behavior of an energy source and facilitate the testing of energy system. This paper presents a study of a photovoltaic (PV) emulator which is formed by a current source, a diode string and some resistors. It is constructed according to the one-diode photovoltaic model. Unlike the previous study, this paper focuses on using the model equations to design the circuit parameters of the emulator to mimic a selected PV panel and evaluate the circuit performance from both electrical and thermal perspectives. A laboratory experimental setup is built and tested to verify the design. The emulator is power efficient a t t he m aximum p ower p oint. The highest power dissipation of the circuit occurs at the open-circuit voltage operating point.

In many applications such as power electronic devices, it is very desirable to employ high power-density transformers, because the available space and allowed weight are very limited. In general, operating at higher frequency would lead to smaller volume and weight of electromagnetic devices, but the core loss could increase significantly. With very low specific core loss and relatively high saturation magnetic flux density, amorphous metal (AM) materials offer great potential. This scientific research aims to study and model the AM properties for developing high performance transformers such as high efficiency and high power density. The use of Amorphous metals as a core material enables high frequency transformers to attain optimum and higher level of efficiencies. This scientific paper discusses: (i) theoretical understanding of the process of magnetisation and a discussion of AM magnetic properties as are useful for design of electrical devices (ii). Characterize the AM materials and to distinguish them on the basis of their distinctive magnetic properties and their usefulness for High frequency High Power Density (HFHPD) Transformers.

Different to the traditional WSN, the energy harvesting WSN(EH-WSN) harvests energy from environment that greatly prolongs its lifetime. Since the communication and routing protocols are very sensitive to energy, and the power supply of EH-WSN is intermittent, it brings quite a challenge for debugging the EH-WSN network. To avoid interfering nodes energy, EH-WSN network debugging is required of energy-interference-free, and nodes are managed to supply energy intermittently. Moreover, the debugger for traditional WSN is not available in EH-WSN networks, and the existing debugger for EH-WSN is only applicable for any single node, failure to obtain the whole information of networks. Accordingly, in this paper, we designed an energy-interference-free data export device for EH-WSN networks (EIF-Export), including hardware and software, which is possible to export the internal data of nodes without affecting nodes operation. Taking into account of the low cost of the device, it is possible to attach a EIF-Export on each of EH-WSN nodes, and the data is collected for further analysis, achieving monitoring for the whole networks. Equipped with LCD, EIF-Export displays key values directly, and the network state is clear and intuitive in visual. EIF-Export, not a debugger, is capable to debug the whole EH-WSN network by obtaining a large scale of data that debuggers are not possible to do. Experiments show that EIF-Export only consumes energy of 8.66nJ/Byte, thus this approach achieves the energy-interference-free data export basically, having no interference to nodes energy and network operation.

UAVs operate on battery or combustible power sources, thus the length of the mission is strongly related to the efficiency of the UAVs. This work discusses multi-UAV system, in which multiple unmanned aerial vehicles cooperate as a group, communicate and process common task(s) (missions). In such case, not only the efficiency of a single UAV is important, but also the efficiency of the entire multi-UAV system. This paper presents the key architecture elements, their roles in the system and proposes algorithms to optimize the system operation as a whole. UAVs are equipped with FPGA processing units that can be reprogrammed to efficiently process certain functions.

In this paper, we have proposed a new code families for spectral amplitude coding optical code division multiple access (SAC-OCDMA) systems. It is referred as modified synchronous square prime code (MSSPC).The proposed new code with ideal in-phase cross-correlation (IPCC) is obtained by modifying the former code. the proposed new partial balanced detection technique utilizing MSSPC can eliminate multiple access interference (MAI) and inhibit phase induced intensity noise (PIIN).Our results show that the code length required by MSSPC is the shortest compared to multi-diagonal (MD) code, zero cross-correlation (ZCC) code, enhanced multi diagonal (EMD) code and generalized matrix partitioning code (GMPC) when to support the same number of users. Under the same conditions, the bit error rate (BER) of the MSSPC system will decrease as the increase of the code weight or the number of mapping. For identical weight and similar code length, MSSPC can support more active users as compared with partitioned diagonal code (PDC).

For identical weight and similar code length, MSSPC can support more active users as compared with partitioned diagonal code (PDC).","PeriodicalId":356324,"journal":{"name":"2018 26th International Conference on Systems Engineering (ICSEng)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134249755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
