Psoriasis is a chronic inflammatory skin disease that have bad effects on the quality of life of the patients. As psoriasis is intractable and its cause is difficult to discover, Traditional Chinese Medicine is proved in China to be a more effective medical way. In Chinese Medicine, decision on prescription is based on ZHENG rather than disease. Only after successful differentiation of ZHENG, can...
Aiming at the characteristics of Senegal type wind turbine, a new type of wind wheel with horizontal structure of wind turbine is studied combined with the characteristics of vertical axis wind turbine and horizontal axis wind turbine. The structure of turbine and the distribution of the surrounding flow field are studied by using ANSYS Workbench software. Simultaneously, for generators installed...
To improve the structure and output characteristics of current 3-DOF PM motors, a type of hybrid drive type permanent magnet 3-DOF motor is researched, which can realize the 3-DOF motion. The spin rotation torque characteristics are further optimized by improving the magnetic field distribution. Based on the introduction of the structure and operation principle of the motor, the magnetic field are...
A blanket noise jamming method based on sawtooth wave frequency shift is proposed in this paper. The characteristic of the jamming signal is analyzed in detail in frequency domain. Due to the frequency modulation, the modulated signal is dis-matched with the matched filter and the output signal's pulse width spreads. The periodic sawtooth wave determines the bandwidth of the jamming signal and the...
With the increasing number of Marine accidents, the task of maritime search and rescue is increasingly difficult. This paper studies a fast, accurate and scientifically valid intelligent equipment which breakthrough maritime search and rescue capability and level for maritime search and rescue. Using sonar detection technology combined with GPS navigation systems and Marine battery energy technology,...
The interactive, experiential, real-time, efficient and comprehensive features of human-computer interactive technology in virtual display make it possible to virtualize products with panoramic, instantaneous and experiential features. The computer aided design based on human-computer interactive technology, through the design and present from shape, color and structure of products, enables designers...
Minimally invasive surgery (MIS) has seen substantial development in recent decades. In MIS, particularly in laparoendoscopic single site (LESS) surgery, the surgical site is always crowded. One potential solution is the magnetic anchored and guidance system (MAGS), which liberates instruments from constraint of the accessing port. Current MAGS are all made by rigid components, which relies on articulated...
In view of the defects of the current cloud computing resource management, which results in low utilization of resources. This paper proposes a new method of resource requirement for the cloud computing environment which is based on situation awareness. The proposed scheme comprehensively evaluates the current situation of the use of resources using AHP (Analytic Hierarchy Process). At the same time,...
This paper presents an evaluation of transient electromagnetic phenomena inside lightning protection systems (LPS) model of truss bridge resulting from direct lightning strikes. The simulation model is base on the coupled transmission line network in the frequency domain combined with the Fourier transform technique, which is employed to evaluate the electromagnetic transient surge current distribution...
An array PSJA is tested in this paper by using high-speed phase-lock schlieren system. The characteristic of the transient flow field is studied. The experiment shows that a series of high-speed blast waves spreads outward after discharge. These blast waves, attenuated to the local sound speed, form a wavefront, which continues to influence the flow field. Due to the interaction between each blast...
A polarization independent ring-shaped gradient index meta-surface for radar cross section (RCS) reduction is proposed. The design can provide a discontinuous gradient phase distribution of reflected wave, which can transform the incident wave to surface wave bounded on the meta-surface. The ring-shaped patches are attached to a high dielectric constant substrate with a perfect electrical conducting...
The commonly-used software fault localization approaches mainly utilize test coverage information and test cases execution results to calculate the suspiciousness of each program entity to identify the location of faults, namely spectrum based software fault localization (SBFL). It had been argued that such techniques are not helpful in real debugging process, since the low accuracy of localization...
A gradient index meta-surface composed of Jerusalem-shaped unit cells is proposed to provide a discontinuous reflected phase gradient distribution for manipulating incident wave in broadband. The Jerusalem-shaped unit cells are located on a high dielectric constant substrate with a perfect conducting ground, and their sizes are adjusted to achieve a desired gradient phase distribution. The proposed...
This paper studies prediction based run-time system reconfiguration strategy to tolerate environment change and hardware malfunction on many-core embedded systems. System reconfiguration will invoke application migration, which may significantly impact system's timing behaviors, therefore, it is vital important to select an appropriate migration strategy after which the system's performance is still...
Mutation Based Fault Localization(MBFL) is a fault localization technique based on mutation analysis, which precisely identifies the location of fault but incurs a high execution cost, since it needs to execute the test suite on a large amount of mutants. Reduction strategies proposed are usually regarding selecting mutation operators or sampling mutants directly, meanwhile at the cost of losing precision...
Localization of sensor nodes is important for wireless sensor networks (WSNs) especially for underwater WSNs (UWSNs). Among the existing UWSN localization approaches, reverse localization scheme (RLS) is an event-driven method suitable for underwater surveillance. RLS adopts the strongest arrival or the first arrival as the direct path, which is however not accurate enough due to the severe multipath...
In underwater wireless sensor networks (USWNs), localizing unknown nodes is essential for most applications while is more complex than that of terrestrial WSNs. In this paper, we propose a range-based localization scheme using deep neural network (DNN). Numerical results suggest that the proposed DNN localization algorithm outperforms traditional schemes using least squares support vector machines...
Accessibility problems such as obstacles on sidewalks can make navigation dangerous for the visually impaired. Detecting these accessibility problems using embedded cameras is a plausible remedy. However, current computer vision algorithms for object detection rely on exhaustive search with high-dimensional features that present a heavy computational burden and incur a long latency, making them non-ideal...
The current virtualization solution in the Cloud widely relies on hypervisor-based technologies. Along with the recent popularity of Docker, the container-based virtualization starts receiving more attention for being a promising alternative. Since both of the virtualization solutions are not resource-free, their performance overheads would lead to negative impacts on the quality of Cloud services...
Parallel programming approaches based on task division/-spawning are getting increasingly popular because they provide for a simple and elegant abstraction of parallelization, while achieving good performance on workloads which are traditionally complex to parallelize due to the complex control flow and data structures involved. The ability to quickly distribute fine-granularity tasks among many cores...
