Cyber attacks are a critical threat to government infrastructure, commercial enterprises and personal devices. When belligerents attack cyber systems, they need to spread laterally to reach high value targets and communicate with their command and control sites. Intuitively, a layered defense including intrusion detection systems will limit the adversary's exploitation of the target. We apply lessons...
Reliability and safety are important properties in the development of complex cyber-physical systems such as autonomous vehicles. Achieving a reliable autonomous vehicle is a challenging problem, as the unpredictability of the environment demands a reliable design methodology. Additionally, current testing procedures for ADAS features on vehicles are exhausting and time-consuming, so that a better...
Based on the perspective of ensuring business continuity through communication and cooperation between the members, the vulnerability of facility management organization under the interference of emergency was studied. The model and simulation of organization network of facility management based on knowing, emotion, consulting and collaboration relationship was put forward. With the case study, there...
Business process is also a complex area which receives much attention in recent years especially in increasing productivity and saving cost. Meanwhile, situation at the company allows existing business processes to be enlarged. This paper proposed the performance measurement based on coloured petri net simulation of scalable business processes, which has purpose to compare the performance of scalable...
With the recent advances in the field of autonomous driving, large scale deployment of such vehicles on public roads is both foreseeable and intended by many manufacturers. In order to not only maintain safety, but also driving comfort and comprehensibility at all times it is necessary to develop and implement modularized and standardized interfaces for planning and information exchange. In this paper,...
Dynamic manipulation of magnetization state (MS) in variable flux permanent magnet synchronous machines (VF-PMSMs) during normal operation based on the torque-speed operating conditions has been shown to significantly reduce machine losses over urban driving cycles. However, the additional losses that are induced during the dynamic MS manipulation have not been evaluated. This paper presents a combination...
In this paper the calculations of the robustness of a network is addressed. After a brief description of the most relevant metrics, our Network Robustness Simulator(NRS) is presented as well as its structure and working model. The NRS computes the robustness I a dynamic scenario, it copes with multiple failures and different types of attack. In particular, the addition of the epidemic based model...
This paper presents different experimental methods for measuring parasitic capacitances and inductances of direct copper bond (DBC) based power semiconductor modules. The found parasitics are compared with finite element simulations to evaluate their accuracy. A very good match of the simulated and measured stray capacitances is found. The parasitics, which are found via simulations and experiments,...
This paper presents an experimental validation of a statistical model of the response of a wire in a reverberant chamber. The statistical model is based on an approach known as Statistical Energy Analysis (SEA); the need to solve Maxwell's equations within the cavity is avoided by employing a relation known as the “diffuse field reciprocity principle”, which leads directly to an expression for the...
The paper presents the results of an analysis of the inter-turn fault effects on the voltage and current waveform of the capacitor discharge through transformer winding. The research was done within the FAIR project for which a measuring and diagnostic system for testing the condition of electrical circuits of superconducting electromagnets system is being developed. Appropriate measurements and simulations...
The given paper presents a method for constructing a QC-LDPC code of shorter length by length adaption from a given QC-LDPC code of maximal length. The proposed method can be considered as a generalization of floor lifting. Making some offline calculation it is possible to construct a sequence of QC-LDPC codes with different circulant sizes generated from a single exponent matrix of QC-LDPC code which...
On a PCB, the high-speed link layout design with high component density has to satisfy strict mechanical and electrical specifications. Not only does the design and manufacturing process become difficult, but also the correlation between measurements and simulations is extremely challenging. In this paper, we focus on the above-mentioned challenge encountered in the measurement correlation process...
In order to improve stability and power quality of the system, there is an essential role in the rapid detection of grid malfunction, particularly in grids with difficult geographical conditions. This article introduces a method which could quickly delineate short-circuit fault location by establishing the corresponding matrix between nodes on grid and short circuit current value. A 50-nodes local...
Recent publications have reported on an innovative technique in which measured antennas are represented as numerical sources in the accurate computation of antennas in complex environments [1-5]. The measured antenna is accurately characterized as a Huygens box in a format compatible with different Computational Electro-Magnetic (CEM) solvers. The numerical representation of the measured antenna is...
The Vehicular Ad Hoc Networks (VANETs), as an important part of intelligent transportation systems (ITS), has been becoming a promising research area. Due to the high mobility of vehicles and intermittent connected topology resulting in the dramatically changing network topology, it is difficult to design a protocol including congestion control mechanism, which is helpful for a well network performance...
The current design drivers for multi-cores, namely performance per watt, scalability and flexibility, make the Networks-on-Chip (NoCs) the de-facto on-chip interconnect. State of the art NoCs can exploit heterogeneous solutions and complex DVFS techniques to fulfill also the variability of the application requirements. Relevant showstoppers to the design of a truly flexible NoC fitting all the possible...
The community structure of complex networks reveals hidden relationships in the organization of their constituent nodes. Indeed, many practical problems stemming from different fields of knowledge such as Biology, Sociology, Chemistry and Computer Science can be modeled as a graph. Therefore, graph analysis and community detection have become a key component for understanding the inherent relational...
Live migration, which allows virtual machines (VMs) to move across distinct physical hosts, is widely adopted for realizing energy saving and load balancing in modern Cloud data centers. However, putting VMs with high correlations on their CPU utilization patterns onto the same host is very likely to trigger overloading incidents and commit Service Level Agreements (SLA) violations, even when the...
Caching at mobile devices, accompanied by device-to-device (D2D) communications, is one promising technique to accommodate the exponentially increasing mobile data traffic. While most previous works ignored user mobility, there are some recent works taking it into account. However, the duration of user contact times has been ignored, making it difficult to explicitly characterize the effect of mobility...
The paper presents a design of SRAM circuit using CNTFET transistors. The complete model describing CNTFET, developed in Stanford University is modified for the purpose of designing a 6T (2×2) SRAM memory cell. The simulation results of the CNTFET SRAM memory cell manifest usability and applicability of the modified CNTFET model in designing digital circuits. The simplified CNTFET model is coded in...
