Collaborative filtering (CF) recommendation is a classic and practical recommendation method. This paper proposes a new method to improve collaborative filtering recommendation, treating the solution of the recommendation problem as an approximate problem, and uses the greedy strategy to solve the optimization problem. In this paper, the similarity calculation method of collaborative filtering algorithm is also modified. Researchers found that this improvement greatly improved the efficiency of the algorithm. Compared with the traditional algorithm, the accuracy has also made great progress. It is a successful experiment.

To improve the execution efficiency, modern processors have introduced branch prediction mechanism, but this also brings new vulnerabilities at the same time. In this paper, attack and defense techniques for processor branch prediction are investigated and classified. Attack techniques are divided into attacks against structural vulnerabilities and attacks against side channel. Also, defense techniques are divided into defense against branch predictors and defense against cache side channels. Then their introduction is given in detail. Next a branch prediction security architecture model is proposed, with its feasibility and security demonstrated. At last, this paper summarizes the shortcomings of the current defense techniques and looks forward to the future trend of branch prediction defense, which provides a reference for the design of processor branch prediction security.

An efficient way to reduce the pressure on communication bandwidth between satellite and ground is to process information and images autonomously, remove incorrect picture data, and communicate useful and usable information. Therefore, this study proposes and develops an open and distributed high-performance integrated processing and computing platform based on the SpaceVPX architecture to support efficient and flexible information processing of satellites in space. The high-performance processing and computing platform is built on the principles of software hierarchy, hardware modularization, and resource heterogeneity, which refines the granularity of parallel computing from devices to hardware modules, improving parallelism and resource utilization, and extending the data plane and control plane of the SpaceVPX architecture from within to between devices, realizing information transfer between halves. At the same time, it acts as a “virtual backplane” bus, enabling information transmission between all hardware modules in the processing and computing platform, and realizing the interconnection of hardware module resources throughout the satellite. A single module has a computational power of 15TOPS and a transmission bandwidth of 200Gbps. Meanwhile, with the design ideas of software-defined network and software-defined hardware, the hardware modules in different physical locations are formed into a logical and organic whole, which effectively supports the goal of multi-use and parallel reuse of the integrated processing and computing platform with computing tasks allocated on demand and hardware modules enabled on demand, and can further enhance the processing and computing capacity of the entire satellite, laying the foundation for deep integration and linkage between the satellite platforms.

Adjustable pulse generator can realize variable bandwidth TDR, variable transmission distance and variable resolution UWB, which has important application value. Our research team uses a variety of pulse generators in the development of Time Domain Reflectometers for high-speed communication networks and high-performance computer test. This article describes in detail the design process of a low-cost width adjustable pulse generator based on a planar microstrip structure. The fast recovery characteristics of the step recovery diode (SRD) are used to generate a step signal with a very short transition time, and then the short route is inverted and combined with the original signal to obtain a Gaussian broadband pulse. We used a simplified pulse shaping circuit, since the width of the pulse signal depends on the length of the short route, so the PIN diode is connected in parallel on the delay line to form a single pole single throw switch (SPST), changing the switching state to control the effective length of the microstrip transmission line, so that the pulse width is adjustable at 250-650ps. Measured results also confirm the simulations.

This paper introduces the application of the unmanned aerial vehicles (UAV) into vehicular delay tolerant networks (VDTNs). In UAV-assisted VDTNs, vehicles adopt the storage-carry-forward mechanism to transmit data, and UAVs can be utilized as mobile relays. For the considered network, we investigate the data transmission problem by jointly considering the relay selection and flight path optimization. We formulate a multi-objective optimization problem, which composes of two parts: a) the transmission delay; b) the flight path cost. Due to the intractability of the formulated NP-hard problem, we design a heuristic algorithm to solve it. Specifically, according to the encounter probability, we present a relay selection scheme, which can limit the maximum number of hops and copies. Then, by considering the flight path cost, we present a flight path optimization scheme based on the improved particle swarm optimization algorithm. Finally, the numerical results show that compared with the current works, our proposed data transmission strategy significantly reduces the transmission delay and the flight path cost.

This paper mainly studies the detection and identification of micro-UAVs by using the radio frequency characteristics of UAV downlink communication signals, and proposes an algorithm to automatically extract key radio frequency signal segment. The algorithm mainly consists of three parts: extracting the signal envelope, determining the threshold adaptively, and extracting the key signal according to the threshold. The experimental results show that the method is proved to be feasible and can be used to extract the radio frequency characteristic part of the downlink communication signal of the micro-UAV.

With the wide application of Web technology and big data, non-relational database (NoSQL database) occupies an increasingly important position. Document database is the most widely used NoSQL database. In order to solve the problems such as copyright protection, data authentication and so on, a document database watermark scheme based on the connected graph is proposed. According to the real documents in the database, the pseudo documents are generated by genetic algorithm, and the watermark is embedded in the modifiable fields of the pseudo documents. The fitness function ensures the integration of real and pseudo documents. So that attackers cannot distinguish between real and pseudo documents, which increases the difficulty of attack. By forming pseudo documents into k-connected graphs with pointer fields, authorized users can distinguish between real and pseudo documents through connectivity. Experimental results show that the scheme achieves good invisibility and robustness.

In this paper, we design and fabricate a novel broadband tunable absorber based on a PIN diode-loaded frequency selective surface (FSS). The absorber is a four- layer structure, and from the top to the bottom are the active FSS (AFSS) layer, the dielectric substrate, the air layer and the metal ground. The AFSS layer is designed as a symmetrical strip with a PIN diode loaded in the middle, which have an adjustable resistance to obtain a tunable and broadband absorption capability. At the same time, a simple bias network is designed to supply an appropriate diode control voltage. The simulations show that the reflectivity can be adjusted below −10dB from 2.3 to 14.5 GHz and the rasorber achieved a broadband absorption. The measurement shows that the frequency range of the rasorber reflectivity less than −10dB is 2.35 to 13.44GHz by adjusting the voltage applied on the PIN diodes. The good agreement between simulations and measurements verifies our design. What's more, the absorber has an overall thickness of 7.524 mm, which is about only 0.059λ of the lowest working frequency and is superior to the conventional passive absorbers. In general, this broadband tunable absorber has great application value in wireless communication, antenna, stealth and radar detection, especially for C-band and X- band radar detection and stealth.

SaaS cloud services support the sharing of software resources among multiple tenants, but the utilization of computing resources by different tenants is different. Some tenants with large business volumes and large amounts of data tend to occupy more CPU and database resources, especially when the SaaS platform provides computing-intensive services such as machine learning, which will cause more serious resource overhead and seriously affect tenants' experience. Therefore, this paper designs and implements a scalable resource provisioning scheme based on cloud functions for multi-tenant architecture. We present a self-defined scheduling protocol, scheduling center, and distributed nodes to alleviate the central server pressure, rationally scheduling and allocating tenant requests by running functional tenant services across nodes.

Satellite Internet system is a direction of the future development of communication satellites. As the combination of satellite communications with the Internet, it becomes an important expansion of information network construction from flat to three-dimensional. The LEO (Low Earth Orbit) constellation places intelligent and flexible demands on the Avionics system. In this paper, we propose an Intelligent Open Avionics System, which can provide a common hardware platform and open core service software to improve the processing capability of Avionics system and the dynamic adding capability of in-orbit missions. Meanwhile, a low-consumption dynamic priority-based satellite resource scheduling method is suggested to achieve optimal resource allocation by autonomously adjusting the priority under different working conditions of satellites and improve the task efficiency with limited resources.
