The conducted electromagnetic interference (EMI) and overvoltage characteristics for a spindle permanent magnet synchronous motor (PMSM) driven by pulse width modulation (PWM) converter are comprehensively presented. The high power, ultra-precision PMSM is applied to a computer numerical control (CNC) grinding machine. The conducted EMI prediction model mainly includes multi-core shielded cable, high frequency (HF) converter and PMSM models. The multi-transmission line (MTL) theory is employed to establish the multi-core shielded cable considering their coupling effect caused by the control pairs. The parasitic capacitance for the PWM converter is calculated by using the analytical formula. The HF equivalent circuit model of the PMSM is obtained combining the methods of impedance measurement and vector fitting method. The influence of the rotor position on the PMSM impedance measurement is considered. The common mode (CM) and differential mode (DM) interference voltage and current both for the output of inverter and the input of PMSM terminals are conducted by using the prediction model. The parametric influence of the long multi-core shielded cables on the overvoltage for the PMSM terminal is discussed.

The advancement of mobile cloud computing (MCC) has the potential to improve communication and information during disaster emergency operation. Many studies from different countries have addressed different approaches to implement mobile cloud technologies during disaster operation. However, there has been a lack of any consolidated evidence-based study to evaluate the MCC from the dual perspectives of disaster emergency situation and technology. In this paper, we provide an extensive study of mobile cloud computing research as a critical system or application based on the latest literature published from 2010 to 2015, and highlights the specific challenges in implementing mobile cloud computing in disaster emergency operation. A systematic literature review was conducted over 4 prominent journals of computer science engineering (IEEE, ACM, ProQuest, Inspec/Elsevier) and the findings were classified into four key challenges of MCC implementation during disaster emergency operation. We present a taxonomy based on the key challenges in this area, and discuss the different solutions taken to solve the challenges. We conclude the paper with a critical analysis of the challenges that have not been solved, and highlight directions for future work.

Model-based analysis and validation using simulation is a helpful tool in the engineering of complex systems. This paper presents a tool chain for the model-based architectural design of avionic fiber-optic networks. A recently proposed framework for simulation-based domain-specific tools is the basis for the development. It supports a model-based design workflow and offers a new 3D graphical user interface for location-based configuration and result visualization of the underlying simulation tool. The benefits of the tool are validated with an application example, in which different topologies for avionic fiber-optical networks are evaluated and compared.

Requirements written in multiple languages can lead to error-proneness, inconsistency and incorrectness. In a Malaysian setting, software engineers are exposed to both Malay and English requirements. This can be a challenging task for them especially when capturing and analyzing requirements. Further, they face difficulties to model requirements using semi-formal or formal models. This paper introduces a new approach, Pair-Oriented Requirements engineering (PORE) that uses an Essential Use Case (EUC) model to capture and analyze multi-lingual requirements. This approach is intended to assist practitioners in developing correct and consistent requirements as well as developing teamwork skills. Two quasi-experiment studies involving 80 participants in the first study and 38 participants in a subsequent study were conducted to evaluate the effectiveness of this approach with respect to correctness and time spent in capturing multi-lingual requirements. It was found that PORE improves accuracy and hence helps users perform better in developing high quality requirements models. © Springer-Verlag Berlin Heidelberg 2014.

With the issue in the traditional remote collaborative work, proposed a collaborative drawing model based on RMI technology. It is easy to work in phase among the remote people by this method and the efficiency of project design and resolve problem has been increased effectively. With the base of anglicizing the principle of the RMI distribute technology, expatiating the key technology goes the system. © Springer-Verlag Berlin Heidelberg 2014.

Inter-data-center asynchronous middleware replication between active-active databases has become essential for achieving continuous business availability. Near real-time replication latency is expected despite intermittent peaks in transaction volumes. Database tables are divided for replication across multiple parallel replication consistency groups;each having a maximum throughput capacity, but doing so can break transaction integrity. It is often not known which tables can be updated by a common transaction. Independent replication also requires balancing resource utilization and latency objectives. Our work provides a method to optimize replication latencies, while minimizing transaction splits among a minimum of parallel replication consistency groups. We present a two-staged approach: a log-based workload discovery and analysis and a history-based database partitioning. The experimental results from a real banking batch workload and a benchmark OLTP workload demonstrate the effectiveness of our solution even for partitioning 1000s of database tables for very large workloads. © 2014 Springer International Publishing Switzerland.

A mobile cloud is a cloud infrastructure connecting to mobile devices with a variety of applications (apps). This paper proposes utilizing bigraphical reaction systems (BRSs) to model and analyze a mobile cloud including its contexts such as mobile location, power consumption, network bandwidth, and latency. Simulations and evaluations are performed by matching the reaction rules of BRS with its current agent, on different usage scenarios of mobile cloud, to demonstrate the validity of the proposed methodology. © 2014 IEEE.
