“…A similar study (Cardellini and Iannucci, 2012) implements Linux terminal server project (LTSP) which is a free and open source terminal server for Linux that allows many users to simultaneously use the same computer. Another study (Leite et al, 2014;Zhou et al, 2015) executes without auto scaling, by simulating user preferences, where an instance is selected either upon their knowledge or the amount of computational resources offered by an instance, it also evaluates the architecture that will scale for a cloud unaware application. Study by Ramanathan et al (2011) illustrates an adaptive complex environment and it accommodates service progression from simple to the complex, achieving the overall mayoral goals to make a city the finest place to live, work, and raise a family.…”

Cloud architectures are becoming an active area of research. The quality and durability of a software system are defined by its architecture. The architecture approaches that are used to build cloud-based systems are not available in a blended fashion to achieve an effective universal architecture solution. The paper aims to contribute to the systematic literature review (SLR) to assist researchers who are striving to contribute in this area. The main objective of this review is to systematically identify and analyse the recently published research topics related to software architecture for cloud with regard to research activity, used tools and techniques, proposed approaches, domains. The applied method is SLR based on four selected electronic databases proposed by (Kitchenham and Charters, 2007). Out of 400 classified publications, we regard 121 as relevant for our research domain. We outline taxonomy of their topics and domains, provide lists of used methods and proposed approaches. At present, there is little research coverage on software architectures for cloud, while other disciplines have become more active. The future work is to develop a secure architecture to achieve quality of service and service level agreements.

Single-phase three-level grid-connected inverter is widely used in high-voltage applications, which can be connected to the grid through a single inductor (L filter) or an LCL filter. The control schemes for an LCLbased grid-connected inverter are more complex than those for an L-based one to damp the resonance of the LCL filter. In this paper, a robust nonlinear direct adaptive fuzzy control scheme is proposed to control both the Land LCL-based inverters. The principle of the inverter is introduced, especially the space vector pulse width modulation method for the single-phase threelevel inverters. Then, the theory of the direct adaptive fuzzy control is described. Based on the theory, the current controller for both types of grid-connected inverters is designed. The closed-loop stability is proved based on the Lyapunov theory. Finally, simulations are conducted to verify the effectiveness of the controller. The results show that both the Land LCL-based grid-connected inverters operate well with strong robustness under the same controller.

“…For example, in [31], fuzzy logic is applied for web-based self-learning and self-adapting outer loop speed control for permanent magnet synchronous motors (PMSMs). The work of Zhou et al is based on Takagi-Sugeno fuzzy logic system approximating the optimal control law for the speed control of the particular PMSM that is to be controlled [32,33].…”

Wireless sensor networks are nowadays used in various applications to facilitate monitoring and actuation tasks, e.g., for smart grids and industrial automation. Some of these applications require guarantees or at least assurances on reliability. Such applications expect predictable throughput and delay, which are hard to maintain in environments with changing radio conditions. QoS-aware MAC protocols capable of handling such environments are well explored. They require however protocol changes and are therefore difficult to deploy. This paper presents an application layer forwarding service that offers proportional differentiation while limiting network load to preserve high utilization and predictability. Demands for capacity are expressed as fractions of the overall channel throughput. We show that this service can be implemented with a cognitive load controller (CLC) based on fuzzy logic and quality assessed with utility functions for application layer packet loss and throughput. We evaluate the CLC for 802.15.4 with CSMA/CA through NS-3 simulations showing that it offers the intended service while adjusting load for high overall throughput and low delay.
