Considering the demands of different location estimation performance and less computational complexity for multiple targets tracking, we present a power allocation scheme in distributed multiple-input multiple-output (MIMO) radar systems. Restricted by different location estimation mean square error (MSE) requirements and transmitted power upper bound, combining sequential parameter convex approximation (SPCA) algorithm and heuristic allocation (HA) algorithm, we propose a modified SPCA (MSPCA) algorithm to address the non-convex optimization problem so that the total power budget can be minimized. Extensive simulation results indicate that, compared with uniform allocation (UA) algorithm and HA algorithm, the proposed algorithm presents approximate optimal power budget with much less computational complexity.

We carry out a careful study of Multi-Objective Evolutionary Algorithm based on Decomposition (MOEA/D) and propose some implementation schemas in the Spark Framework. Focusing on the setting of weight vectors, we propose two partitioning schemas, which define the distribution mode for the algorithm. The first partitioning schema is to define a partition by a group of weight vectors that are close to each other. The other schema is to distribute close weights to different partitions. Experiments in distributed framework indicate that, for most benchmarks, the schemas in distributed framework can obtain better results and better performance in expansibility.

The Design of new wireless communication systems.for industrial applications, e.g. control applications, is currently a hot research topic, as they deal as a key enabler for more flexible solutions at a lower cost compared to systems.based on wired communication. However, one of their main drawbacks is, that they provide a huge potential for miscellaneous cyber attacks due to the open nature of the wireless channel in combination with the huge economic potential they are able to provide. Therefore, security measures need to be taken into account for the design of such systems. Within this work, an approach for the security architecture of local wireless systems.with respect to the needs of control applications is presented and discussed. Further, new security solutions based on Physical Layer Security are introduced in order to overcome the drawbacks of state of the art security technologies within that scope.

Centralized electrical storage system management in islanded micro-grids is treated both theoretically and experimentally. An overview of the types of distributed islands in Wi-Fi Long Distance networks is the starting point, followed by examples of WiLDNets and associated reliability problems. Presentation of an archetypical tree structure communication system serves to introduce a centralized management system that may be used to improve reliability of multi-community private networks. An existing Wi-Fi long distance testbed with distributed storage serves as an islanded micro-grid for experimental study. Centralized management algorithms are tested. The results are generalized to the case of large meshed communication system.

Grid connected Solar Photovoltaic (PV) generation systems.are becoming popular. Solar PV systems.will supply power to the local loads and also pump the power to the grid when local demand is less. Line impedance and load variations will adversely effect the efficiency of the power pumping capability of the system. This paper describes how the line impedance and loading influence the voltage profile in the distribution network with distributed solar PV systems. In this context, an analysis on the voltage profile due to the variation of load change and line impedance are investigated in a representative low voltage (LV) distribution network. The system is simulated using MATLAB/SIMULINK platform.
The efficiency of industrial processes depends on how well the processes can be controlled and this affects the quality, use of resources as well as the environmental impact. Advanced monitoring and control solutions ...

Community detection in complex networks has a wide range of applications such as detection of cyber-communities in social networks, recommendations based on the interest group, and estimating hidden features in a social network. In distributed frameworks, the primary focus has been scalability. However, the accuracy of the algorithm's output is also critical. We propose the first distributed community detection algorithm based on the state-of-the-art CEIL scoring function. Our algorithm, named DCEIL, is fast, scalable and maintains the quality of communities. DCEIL outperforms the existing state-of-theart distributed Louvain algorithm by 180% on an average in Normalized Mutual Information (NMI) Index and 6.61% on an average in Jaccard Index metrics. DCEIL completes execution for 1 billion edges within 112 minutes and outperforms state-of-the-art distributed Louvain algorithm by 4.3x. DCEIL critically exploits three novel heuristics which address the existing issues with distributed community detection algorithms that have the hierarchical structure of CEIL or Louvain methods. Further, our proposed heuristics are generic as well as efficient, and we illustrate their efficacy by enhancing the accuracy of distributed Louvain algorithm by 22.91% on an average in Jaccard Index, and the average execution time by 1.68 x over popular datasets.
