Relying on the reception and analysis of signals already present in environment, has various applications across different domains, from acoustics to electromagnetics. However, growing signal bandwidth poses tremendous challenges data transmission, highlighting advantages compressive sensing (CS) technique. In this study, we investigate direct position determination (DPD) using sub-Nyquist sampling directly without reconstruction full first. Leveraging Hadamard matrix as CS measurement...
This paper focuses on the trusted vessel position acquisition using passive localization based booming low-earth-orbit (LEO) satellites. As high signal-to-noise ratio (SNR) reception cannot always be guaranteed at LEO satellites, recently developed direct determination (DPD) is adopted. For satellite-based systems, an efficient DPD challenging due to excessive exhaustive search range leading from broad satellite coverage. In order reduce computational complexity, we propose a time difference...
As an important branch of mobile Ad Hoc network technology, Vehicular hoc Network (VANET) is a promising technology in Intelligent Transportation Systems (ITS). It required to evaluate any VANET design which the simulator with vehicular mobility model should be more realistic. In order improve authenticity model, paper analyzed JE2013 lane-changing SUMO and proposes new based on model. The takes into account motorway scene, analyzes change vehicle velocity calculates position coordinate...
Recent years have witnessed an increasing interest in online video affective content analysis, since having a better understanding of the emotions videos can facilitate many applications including retrieval and classification. Research computing requires ground truth data for training evaluation. The live commentary (also known as 'danmaku', 'barrage', or 'bullet comment') is quite popular recent years, but few researchers paid attention to information analysis videos. In this paper, we...
The rapid growth of maritime transportation and its regularization have imposed an increasing demand for developing a global surveillance capacity. existing cooperative traffic monitoring relies on the shipborne automatic identification system (AIS), which is now confronting severe security threats due to vulnerabilities AIS at both implementation protocol levels. In this article, possibility passive signal localization using low Earth orbit satellite constellations investigated, provides...
With the rapid development of various online video sharing platforms, large numbers videos are produced every day. Video affective content analysis has become an active research area in recent years, since emotion plays important role classification and retrieval videos. In this work, we explore to train very deep convolutional networks using ConvLSTM layers add more expressive power for models. Network-in-network principles, batch normalization, convolution auto-encoder applied ensure...
This paper presents an initial effort for the trusted geolocation of Internet Things (IoT) devices based on booming low-earth-orbit (LEO) satellites. As high signal-to-noise ratio (SNR) reception cannot always be guaranteed at LEO satellites, recently developed direct position determination (DPD) approach is adopted. For such passive localization systems, efficient DPD execution challenging due to vast coverage area In order reduce computational complexity, we propose a method narrow search...
When testing aspheric surface by computer generated hologram (CGH), there are some engineering problems in experiments. Within a lot of experiments, unknown conditions appeared, and we analyzed two them detail simulated Zemax. The unwanted diffraction orders maybe bring ghost image, ring source is simple method to eliminate it. parallelism error CGH substrate will non-rotational symmetric test result, which shown as coma. size the coma related degree angle compared with origin position. And...
