We investigate conditional adversarial networks as a general-purpose solution to image-to-image translation problems. These networks not only learn the mapping from input image to output image, but also learn a loss function to train this mapping. This makes it possible to apply the same generic approach to problems that traditionally would require very different loss formulations. We demonstrate...
Quality of Service (QoS) is often essential when the service consumer looks for a single service from a large pool. However, QoS of a composite service is aggregated in a rough way because the concrete service providers in the composition are seen as independent ones. In reality, business relationships such as dependencies and conflicts often exist among service providers, which unavoidably affect...
The vulnerability analysis is vital for safely running power grids. The simultaneous attack, which applies multiple failures simultaneously, does not consider the time domain in applying failures, and is limited to find unknown vulnerabilities of power grid networks. In this paper, we discover a new attack scenario, called the sequential attack, in which the failures of multiple network components...
Combinatorial Testing (CT) is a black-box testing technique, which is used to test parameterized systems. Real applications often have some special testing requirements, especially parameter constraints. Our experimental results show that existing CT test generators cannot deal with constraints very well as the number of constraints increases. This is due to their constraint solving mechanisms, where...
The paper introduces the excitation system parameter test of No. 1 unit in Gansu Hanpingzui Hydropower Station. According to the field test data, the excitation system model for stability calculation is set up and the model parameters are obtained. No-load 5% step response of No. 1 unit is simulated by BPA simulation software. The simulation result indicates that the mathematical model and its parameters...
SLAs play an important role for the QoS-driven service composition. Meanwhile, the temporal constraints are one of the main elements in the management of SLA especially in specifying the validity period of the QoS offers. In practice, the temporal constraints should be generated dynamically by taking the resource capability of the provider into account. The generation should consider various parameters...
