Automated segmentation of intracranial arteries on magnetic resonance angiography (MRA) allows for quantification of cerebrovascular features, which provides tools for understanding aging and pathophysiological adaptations of the cerebrovascular system. Using a convolutional autoencoder (CAE) for segmentation is promising as it takes advantage of the autoencoder structure in effective noise reduction...
Aimed at abnormal score from evaluation experts, real data from Shanghai double-blind sampling system of graduate dissertation and thesis between 2013 and 2014 have been in depth analysis and mining. Some basic judgment rules of abnormal score are summed up, and monitoring model for abnormal score is proposed. By the least squares method and the multiple regression models, the equation of monitoring...
With the development of the smart meters, demand response (DR) is able to provide fast ancillary services, such as frequency control. Some recent studies demonstrated that DR can perform like thermal generators in the frequency control. However, little attention has been paid to DR's effect on the electromechanical oscillations of the power system. Fast-response DR can not only affect system frequency,...
As more and more technologies to store and analyze massive amount of data become available, it is extremely important to make privacy-sensitive data de-identified so that further analysis can be conducted by different parties. For example, data needs to go through data de-identification process before being transferred to institutes for further value added analysis. As such, privacy protection issues...
Because of the worldwide aging population, more and more elders suffer from dementia. Nowadays, it is inconvenient and time-consuming for doctors to diagnose whether elders who live independently have dementia because lots of diagnostic questions on a checklist must be asked first, and part of them even require a long-term observation. In order to help doctors and make this diagnostic process easier,...
In smart grids, demand-side management (DSM) is one of the important function for both customers and utility, since it can reduce the total electricity cost of each customer, meanwhile, alleviate the aggregate peak-to-average ratio (PAR) subjected to real-time pricing (RTP) policy. On the other hand, while bidirectional charging/discharging Plug-in Electric vehicles (PEV) become more general, the...
For a visual servo system, there usually exists the problem of time-delay likely caused by long image processing and data transmission. The visual servo system of our robot is subject to two main limitations stemming from the specific commercial mobile manipulator, of which one is the large time-delay due to image transmission, whereas the other is failure to directly command each joint velocity as...
With the explosive growth of mobile data demand, exploiting millimeter wave (mmWave) frequency band is regarded as a promising solution in the fifth-generation (5G) cellular networks. In each generation of cellular networks, cell planning (CP) is the primary stage before deployment. However, due to mmWave's characteristics being different from traditional microwave at relatively low frequency, CP...
This paper presents a hybrid system of applying homeostatic drives theory and stimuli from environment or human on a robot, aiming to solve the increasing need of elder caring in modern aging society. Through reinforcement learning with human feedback, the robot is enabled to make appropriate decisions by reviewing its own motivation, environment stimuli and human inputs, allowing the robot to finish...
This paper proposes a new method for human posture recognition from top-view depth maps on small training datasets. There are two strategies developed to leverage the capability of convolution neural network (CNN) in mining the fundamental and generic features for recognition. First, the early layers of CNN should serve the function to extract feature without specific representation. By applying the...
A voltage-controlled oscillator (VCO) for 5-GHz band application is presented in this paper. The VCO is designed for low voltage-supply, low power consumption, low phase noise and large tuning range based on TSMC 0.35μm SiGe BiCMOS process. To analyze the noise, the noise model of this design is deduced. The center frequency of VCO is 5.5GHz and oscillation frequency range is from 5.1 GHz to 5.9 GHz,...
As robots participate in human's daily activities more and more frequently, mobility performance has become one of the main factors determining how robots will share an environment with humans harmoniously in the near future. Among several different kinds of mobile platforms, using omnidirectional configurations is gradually becoming a trend in the robotics community; however, few researchers have...
In an ageing society, we expect that a robotic caregiver is able to persuade the elderly to perform a healthier behavior. In this work, pragmatic argument is adopted to make the elderly realize that a choice beneficial for health is really worthwhile, such as eating suitable fruits. Based on this concept, an adaptive recommendation dialogue system through pragmatic argumentation is proposed. There...
This manuscript introduced the modularized structural design of a medium sized quadruped robot with desired compact and dexterous mobility. In detail, the ball screw transmission and the four-bar linkages mechanism were adopted to construct the quadruped robot, and then the relationship between the torque of the knee joint and the torque of the motor was modelled and analyzed. Moreover, the mechanical...
In this work, ESD immunity enhancement for the HV n-channel LDMOS with source-end discrete islands fabricated by a TSMC 0.25 μm 60 V process was investigated. An nLDMOS device always has poor ESD capability. If discrete n+ islands are formed in the source end of an nLDMOS transistor, the It2 value of this DUT is upgraded by 4.92% as compared with that of the reference nLDMOS. Meanwhile, if an nLDMOS...
A wireless power transmission device consists of a transmitting module and a receiving module. Unlike most wireless power transmission researches, this paper based on the research that adopts the 15-volt direct-current power as its auxiliary power, and inversion efficiency is also considered in relation to system transmission efficiency. The research made the best of Control IC SG3525 in inversion...
In deep neural networks, inputs in each layer are affected by all previous parameters of input layers, so even small changes in input distributions to the network are delivered to internal layers, for leading to differences between source domain and target domain, which is known as covariate shift. Batch Normalization(BN) is designed to address the issue, and makes normalization for each training...

Meta-search engine is a comprehensive search tool, which is build base on those member search engines. All result entities reported by member search engines are merged into one ranked list according to their quality. It is well knowing that the core problem in meta-search engine is how to merge the results and provide user with a more effective rank list. This paper dealt with a synthesized merging...
