This model serve managers decision makers further strong data support.

In the development and application of intelligent learning environments, an important trend is to integrate characteristics proper human, such as personality emotion, into interface agents, with aim providing student a more personalized friendly environment. The companion kind very useful agent in Therefore, exploring model emotion crucial problem make it hominine believable. this paper, related works on emotions psychology artificial intelligence are reviewed briefly, framework Personality...

A gyroscope-free inertial measurement system(GFIMS) uses only accelerometers to measure angular velocity and specific force. It is a low-cost system? But the value of computed by outputs accelerometers, its accuracy lower than that conventional system equipped with gyroscopes. So it very necessary research on high real time estimation algorithm in IMS. Unscented kalman filter(UKF) novel filter method for nonlinear gauss system, which can obtain higher conventional. In this paper, UKF used...

The navigation accuracy is seriously affected by installation errors of accelerometers in Gyroscope Free Strap-down Inertial Navigation System(GFSINS). So, the have to be calibrated before used and output must compensated while GFSINS on working. In this paper, consider a 12-accelerometer constituted with four three-axis accelerometers, new position error calibration method based invariance vector module value different coordinates sensitive direction principle coordinate transformation are...

When the star navigation system working during day, strong sky background radiation lead to a result that detect target light is too weak, in field of view, because limitation on number star, usually choose single work mode. In order improve reliability airborne SINS/CNS integrated system, meet demand long-endurance and high precision navigation, use tight combination way, patrol algorithm get position attitude. There exists filtering divergence problem model error measurement noise...

The availability of so many computer-based travel-demand forecasting models provides transportation planners with powerful and flexible tools in the modeling phase their planning or traffic-impact studies, but it has confused users selection an appropriate model for a particular study. It is commonly recognized that none existing perfectly suited all network scenarios traffic conditions. A strong one application scenario may be weak different scenario. comparative study presented two widely...

Detection, tracking, characterization and identification of space targets orbiting the Earth is one main tasks surveillance system. Spatial target image feature extraction can find out some descriptions that reflect essence from original image. The moment describes statistical characteristics grayscale by moments each order distribution, which effectively shape information target. A Hu extension proposed, a method for spatial images proposed based on this. It solves problem loss when...

Accurate understanding of urban land use change information is great significance for planning, monitoring, and disaster assessment. The Very-High-Resolution (VHR) remote sensing images detection on features has gradually become mainstream. However, most existing transfer learning-based models compute multiple deep image features, leading to feature redundancy. Therefore, we propose a Transfer Learning Change Detection Model Based Feature Selection (TL-FS). proposed method involves using...

Underwater wireless optical communication (UWOC) offers high-speed, low-latency data transmission but is challenged by absorption, scattering effects from particles and turbulence, receiver locational uncertainty due to ocean dynamics. In this paper, we present a novel attenuation model that, for the first time, simultaneously accounts combined of particles, in non-line-of-sight (NLOS) multiple underwater channel. Utilizing model, analyze photon process quantify impact on channel...
