## 2 The Topics of Applied System Innovation  
This Special Issue selected 10 excellent papers from 50 papers relevant to the topic of applied system innovation presented at the IEEE ICASI 2018. The published papers are introduced as follows:  
[PERSON] et al. reported on \"An IP Multimedia Subsystem Services Proxy Gateway Based on a JAVA Dynamic Module System\" [1]. This paper proposes an Open Service Gateway Initiative (OSGi) basedIP multimedia subsystem (IMS) service gateway, in which OSGi technology is the dynamic module system for JAVA. The proposed gateway is authorized by a personal self IMS device such that the IMS services were accessed by non-IMS devices in this paper. Moreover, these non-IMS devices rely on different networks to access technologies and network protocols and the IMS service gateway proposed here adopted the OSGi framework with no problem of integration. [PERSON] et al. reported on \"An Integrated Credit-Based Incentive Protocol for Symbol-Level Network-Coded Cooperative Content Distribution among Vehicular Nodes\" [2]. In this paper, based on distinct levels of node interests and selfishness on different content information, the authors, first, categorized vehicular nodes into four classes, that is, destination, intermediate, irrelevant, and overhearing, and then, designated their associated credit-based incentive approaches. Secondly, the authors modified the flow of traditional symbol-level network coding (SLNC) based cooperative content distribution operations and proposed the content bitmap to realize the difference of network-coded content pieces among vehicular nodes. Furthermore, the authors rigidly combined the proposed credit-based incentive approach with the modified SLNC-based cooperative content distribution operations in Social Code to encourage all classes of vehicular nodes to increase their incentives for sharing content data in the cooperative content distribution process. Finally, the authors performed NS-2 simulations on a street map of downtown Taipei, Taiwan and exhibited the high efficiency of Social Code over related credit-based incentive approaches by analyzing the following performance metrics: average decoding percentage, file downloading delay, and credits with respect to different file sizes and total numbers of vehicular nodes. [PERSON] et al. reported on \"Highly Reliable and Efficient Three-Layer Cloud Dispatching Architecture in the Heterogeneous Cloud Computing Environment\" [3]. In this study, a Three-Layer Cloud Dispatching (TLCD) architecture was proposed to enhance the performance of task scheduling. In the first layer, the tasks need to be distinguished into different types by their characters. Subsequently, the cluster selection algorithm is proposed to dispatch the tasks to appropriate service clusters in the second layer. In addition to this, a new scheduling algorithm is proposed in the third layer to dispatch the task to a suitable server in a server cluster to enhance the scheduling efficiency. Basically, the best task completion time was obtained in their TLCD architecture. Furthermore, load balancing and reliability was achieved under a cloud computing network environment. [PERSON] et al. reported on \"Trajectory Tracking between Josephson Junction and Classical Chaotic System via Iterative Learning Control\" [4]. This article addressed trajectory tracking between two nonidentical systems with chaotic properties. To study trajectory tracking, the authors used the Rossler chaotic and resistive-capacitive-inductance shunted Josephson junction (RCLs-JJ) model in a similar phase space. In order to achieve goal tracking, two stages were required to approximate target tracking. The first stage utilized the active control technique to transfer the output signal from the RCLs-JJ system into a quasi-Rossler system. Next, the RCLs-JJ system employed the proposed iterative learning control scheme in which the control signals are from the drive system to trace the trajectory of the Rossler system.
