As the Internet of Things (IoT) industry grows, risk network protocol security threats has also increased. One that come under scrutiny for its vulnerabilities is MQTT (Message Queuing Telemetry Transport), which widely used. To address this issue, an automated execution program called fuzz been developed to verify ofMQTTbrokers. This provided with various random and unexpected input data monitored different responses, such as acknowledgments, crashes, failures, or memory leaks. generate a...

Nuclear magnetic resonance (NMR) oscillator is an optical atomic sensor which developed to measure inertial angular velocity with navigation grade accuracy. It utilizes semiconductor laser, miniaturized shield and atom vapor cell realize nuclear resonance, pump detection in a very small volume (about 10cc 100cc). NMR much more compact than other classic gyros such as fiber optic gyro (FOG), so it potential substitution of FOG the next generation IMU. To achieve this goal, essential analyse...

Improving cluster utilization by scheduling and decision-making is a long-standing research problem for cloud vendors. The workload models can improve providing provision of the future public scheduler. However, capturing correlations in real traces was proven to be hard former research. In this paper, we introduce conditional generative adversarial network (CGAN) based model, which provide long-time cluster. proposed approach, model generated three-stage training with GAN, not limited...

Axis orientation stability has a great effect on the long-term drift performance of nuclear spin comagnetometers that utilize alkali atoms to detect magnetic moment ensembles. Previous studies have analyzed sensitivity influence misalignment angle and demonstrated post-processing calibration method in transverse polarized comagnetometer, but there is no study traditional longitudinally setup. We propose an innovative biaxial differential detection monitor comagnetometer then eliminate it...

Message Queue has been long and widely used in cloud-based service, playing the role of communicating applications across multiple platform asynchronously. As a part Oriented Middleware(MOM), it provides solutions for data transfer distributed systems. Many open source message queues, such as Apache ActiveMQ, RabbitMQ, Kafka, are designed to be scalable durable process stream with low latency high throughput. In this paper, we introduce recurrent neural based network which proven solve...

Magnetic field measurement is fundamental to nuclear magnetic resonance rotation sensors (NMRRS). A phase-locked loop (PLL)-based with two isotopes commonly applied observe the field. However, phase-loop and frequency-loop of cannot be optimized simultaneously by a PLL-based method. In this paper, an approach based on linear active disturbance rejection controller (LADRC) proposed for synchronous control isotopes. Meanwhile, frequencies are observed extended state observers (LESOs). The...

Navigation technology is crucial to the national defense and military, which can realize measurement of orientation, positioning, attitude speed for moving object. Inertial navigation not only autonomous, real-time, continuous, hidden, undisturbed but also no time-limited environment-limited. The gyroscope core component inertial system, whose precision size are bottleneck performance. However, nuclear magnetic resonance characteristic advantage high small size. Nuclear meet urgent needs...

The nuclear magnetic resonance gyroscope serves as a new generation of strong support for the development high-tech weapons, it solves core problem that limits long-playing seamless navigation and positioning. In NMR gyroscope, output signal with atomic precession frequency is detected by probe light, final crucial photoelectric light directly decides quality gyro signal.
