Monotonic scaling-down of CMOS integrated circuit (IC) technologies is rapidly approaching to its physical end, yet advances in ICs will continue. Instead of one-dimensional (1D) scaling dawn, one apparent solution is lateral integration of heterogeneous devices in 3-dimensional (3D) fashion, which opens great opportunities to make more complex Si-based microsystems for unlimited applications well...
Heterogeneous CPU-GPU systems have recently emerged as an energy-efficient computing platform. A robust integrated CPU-GPU simulator is essential to facilitate researches in this direction. While few integrated CPU-GPU simulators are available, similar tools that support OpenCL 2.0, a widely used new standard with promising heterogeneous computing features, are currently missing. In this paper, we...
The authenticity of human resource information has become an important factor that affects the cost and efficiency of human resource management. With the rapid development of mobile devices and Internet technology, various human resource risks caused by information asymmetry constantly bring economic loss, and even a fatal blow, to enterprises. Based on Blockchain(BC), this paper aims to combine traditional...
With the gradual improvement of the level of educational information, the idea of education big data has gone deep into people's minds. More and more teaching staff and researchers have the consciousness of the data needs, and expect to do the data mining and learning analysis of education big data. However, the most realistic and basic problem they have in the process of carrying out research is...
The simulator based on interactive virtual reality can solve many drawbacks in traditional surgery training, and it is widely used to train apprentices. A real-time and realistic guidewire model is a challenging task for the simulator, which is used to simulate minimally invasive vascular surgery. In this paper, we propose a fast and stable physical model to simulate the behavior of the guidewire...
Intellectual-property (IP) rights refer to the ownership of intellectual achievement.Microfilms are getting popular nowdue to their low production cost. However, their IP rights are often violated as microfilms can be copied and transmitted via mobile devices easily.This paper proposes using blockchain (BC) to develop an IP-protection model for microfilms. Information registered at a BC cannot be...
The 3D X-ray Computed Tomography (CT) is used in many domains. In medical imaging and industrial Non Destructive Testing (NDT) applications, this technique becomes of great interest. In these applications, very often, we need not only to reconstruct the image, but also to detect the contours between the homogeneous regions of the piecewise continuous image. Generally, contours are obtained by a post...
In this paper, we address the problem of detecting and segmenting partial image blur from a single input image. Instead of assuming particular image priors or requiring additional user annotation, we propose a novel learning framework which jointly solves the tasks of blur kernel estimation and image blur segmentation, so that partial image blur can be automatically separated from the remaining parts...
Distributed cache at mobile user devices and small base stations (SBSs) can improve the efficiency and reduce the delay for content dissemination in heterogeneous cellular networks (HetNets). One major challenge lies in the limited storage capacity of the participating mobile devices and SBSs. This paper investigates the design of an effective distributed content cache policy with heterogeneity (DCP-H)...
Tone plays an important role in the speech perception for tonal languages. However, the monotonie speech of conventional electrolarynx (EL), which lacks of frequency variation, greatly decreased the intelligibility. For purpose of improving the speech quality of Mandarin Chinese (Mandarin). We designed a new type of EL that can produce the four types of tones in Mandarin, and evaluate its performance...
Different from the conventional whispering-gallery-mode sensing using reactive interaction, the dissipative interaction is proposed and demonstrated to detect single nanoparticles which are lossy and with an ultra-small real part of the polarizability.
We identify experimentally the efficiency of the free-space coupling through measuring the threshold of stimulated Raman scattering in a slightly deformed microtoroid cavity, and the measured efficiency is up to 30%.
Compositional barrier functions are proposed in this paper to systematically compose multiple objectives for teams of mobile robots. The objectives are first encoded as barrier functions, and then composed using AND and OR logical operators. The advantage of this approach is that compositional barrier functions can provably guarantee the simultaneous satisfaction of all composed objectives. The compositional...
Currently, fast advancement of digital electronic communication technology enables learning being underway in a virtual and multimodal form. This study, through qualitative analysis of the tendency of virtual learning community, the potential of pervasive computing technology as well as the modality research in classroom context, discussed the prospects of applying pervasive computing technology to...
X-ray angiography is a common method for image-guided navigation comprising surgical devices and vessel contours detection which can offer visual feedback to physicians. However, for the sake of both physicians' and patients' health, the contrast agent is injected intermittently and in a low dosage, so the X-ray images are not always of adequate quality for visual examination. So the navigation, which...
Network reconfiguration is the key technology to realize the autonomous operation and safety enhancement in aircraft power distribution system. The goal of reconfiguration is to achieve maximal power supply under different fault conditions. This paper proposes a power priority based reconfiguration algorithm. To verify the validity of the algorithm, an aircraft power distribution system is discussed...
As more electric aircraft power systems grow in complexity and power rating, the design, evaluation and testing of such systems become quite challenging tasks, while real-time simulator based hardware-in-the-loop (HIL) technique is considered a cost/time-effective solution. This paper applies RT-LAB to real time simulation for aircraft electric power system (EPS) with hardware Bus Power Control Unit...
In this paper, an energy-efficient power allocation problem is studied for a secure full-duplex (FD) relay network. The problem is formulated as a nonconvex optimization program to achieve the maximum of secure energy efficiency with power constraints and a preset secure quality-of-service (QoS). By analyzing the structure of the objective function, we found that the problem can be solved by leveraging...
Nowadays the indoor location context becomes an important element in a number of real applications. Use of WiFi signals to fulfil the location detection of WiFi-enabled devices is a promising approach. In this paper an AP (Access Point)- centred indoor positioning system is proposed to address some common concerns in the conventional MH (Mobile Handheld)-based positioning system, such as excessive...
Surrogate modelling and model management are key points for evolutionary optimization of chemical processes. This paper proposes an evolutionary algorithm with the help of adaptive surrogate functions (EASF), in which approximate models' establishment and management are combined to search the optimal result. To construct an appropriate surrogate model, a new hybrid modelling framework with adaptive...
