Recently, wireless caching techniques have been studied to satisfy lower delay requirements and offload traffic from peak periods. By storing parts of the popular files at the mobile users, users can locate some of their requested files in their own caches or the caches at their neighbors. In the latter case, when a user receives files from its neighbors, device-to-device (D2D) communication is enabled...
In recent years, the application of solder interconnections in some special electronic products and the requirement for solders with higher reliability has promoted the emergence of novel interconnect materials. Arising from increasing demand for portability and miniaturization in electronic products, two key fundamental factors have been identified as causes of reliability problems: 1. thermal stress,...
Smart video surveillance systems are essentials in modern environments to ensure safety and security for lives and property. In order to capture critical clues of reconnaissance, it is important to automatically and dynamically control the surveillance sensitivity and quality for detecting abnormal/suspicious events to perform high quality monitoring. In this work, we design a smart video surveillance...
Occlusion is one important problem in single object tracking. However, conventional methods are not capable of making full use of the spatial information because of occlusion, which may lead to the drift. In this paper, we propose a robust patches-based tracking method via sparse representation, namely RPSR, which selects the unoccluded patches, and adaptively assigns larger contribution factors to...
To reduce energy waste in future cellular networks, the most effective and reliable method is to close idle base stations when not needed, but how to find the proper and optimal method to control the target cell and the adjacent ones are still blank according to recent researches. In this work, we extend our research in cooperative scheme, and figure out a heuristic control method of eNodeBs in GREEN...
Previous work on 802.1 1x (Wi-Fi) power control have focused almost exclusively on the mitigation of interference from data frames. Since Wi-Fi wireless access points are increasingly ubiquitous, it is now common for an 802.1 1x client to be able to receive signals from more than 10 APs simultaneously in a modern urban operating environment. At such high densities, we found that the interference from...
Sketch is used for rendering the visual world since prehistoric times, and has become ubiquitous nowadays with the increasing availability of touchscreens on portable devices. However, how to automatically map images to sketches, a problem that has profound implications on applications such as sketch-based image retrieval, still remains open. In this paper, we propose a novel method that draws a sketch...
Existing dual image deblurring methods usually model blurred image pairs being taken from exactly the same viewpoint and restore a single clear image. This imposes a strong assumption that the latent clear images of both images must be completely identical. In contrast to this restricted scenario, we assume that the restored pair are different, but can be approximated by image warping due to small...
Recently, the standardization of LTE-Advanced is in rapid process and more and more people concentrate on the system performance of special transmission scenarios and make improvement in current architectures because studies on both system throughput and capacity in physical layer are nearly saturated. The standardization of 3GPP LTE-Advanced release 11 has been opened in the early 2011 and Distributed...
The occurrence regulation of Spodoptera litura was studied according to the continiuous years's data investigated in tobacco fields and weather data of Chenzhou and Ningyuan in Hunan. Results showed that generations of Spodoptera litura are 4–4.5 with the effective accumulated temperture per year and the actual generations of Spodoptera. litura is in accordance with the predicted generations in Hunan...
Current markerless 3D registration methods usually utilize a single specified category of natural features. However, the richness of various natural features is ignored. They cannot meet users' diversified registration requirements. This article proposes an integration strategy of 3D registration methods based on multiple natural features. Utilizing feature detection and tracking and 3D registration...
In this paper, we presented the corpus collection procedure and proposed the effective feature representation. We collected the emotional speech from 50 male and 50 female speakers and the corresponding statistics of the corpus was also demonstrated. The emotional speech corpus was further processed manually for the feature extraction and classification experiments. After introducing the feature generation...
