IoT applications consist of a series of correlated IoT services. Compared with traditional services, IoT services have new features in distribution, dependency, security and dynamism, which pose new challenges to the assurance of performance for cloud-based IoT services. Service scheduling on the cloud is an effective approach to guarantee service performance. Taking into account the complex contextual information of IoT services, this paper proposes a Context-Aware Online IoT Service Scheduling Approach in Cloud Environments. First, based on the characteristics of IoT services, a description of the IoT service scheduling problem is given, including the constraints of transforming the contexts of IoT services into scheduling. Then, the service scheduling problem is mapped to a scheduling plan prediction problem based on a neural network approach. To verify the effectiveness of the method, two baseline algorithms were selected and simulated on the WorkflowSim platform together with the method proposed in this paper. In comparison, our method is found to have similar scheduling costs with the optimization method, but can improve the efficiency when generating the scheduling plan, which can better meet the demands of low time delay for online scheduling under the conditions of dynamic changes in IoT context. © 2022 SPIE.

To meet the spectral requirements of solar simulators for ground testing and calibration of infrared space optoelectronic devices, a broad-spectrum solar simulator has been designed and studied. A xenon lamp is used as the light source for the visible spectrum, and a cavity black body is used as the radiation source for the mid-infrared spectrum. An infrared field lens set is designed to match the infrared radiation aperture with the visible light beam. After being combined by the beam splitter, the combined beams are then collimated by the off-axis parabolic mirror, achieving uniform illumination on the target surface. Experimental results show that the solar simulator matches the AM0 standard spectrum within the 0.4 μm~0.7 μm range with a consistency level of 0.9~1.1. The effective illuminated area is 150mm in diameter, with the divergence angle of ±1.7°. In the band of 3 μm~5 μm range, the integrated irradiance satisfies with theoretical predictions. This design not only enhances the authenticity of the spectral range, but also provides the radiation resistance and stray light interference resistance of infrared devices. It also lays the foundation for the design of larger-aperture, wider-spectrum solar simulators. © 2025 SPIE.

In this paper, the three-dimensional magnetic diffusion governing equations of an electromagnetic railgun are derived based on Maxwell's equations and coupled with the energy equations. The finite element method is used to calculate the current density, temperature, and electromagnetic force distribution for armature velocities of 0, 200, 600, and 1200 m/s. The results show that there is a current concentration phenomenon on the rail's inner surface and the trailing edge of the contact interface;the temperature rise of the rail along the moving direction of the armature tends to decrease, and ablation occurs at the corner of the moving armature's trailing edge. An increase in the velocity of armature movement results in an increase in the electromagnetic forces on the armature and contact surface. This model can effectively represent the variation of each physical quantity with velocity and provide direction for the optimal design of the rail and armature. © Published under licence by IOP Publishing Ltd.
