A new vertical tunnel FET design based on black phosphorus is presented in this paper adopting asymmetric layer numbers for top and bottom layer with undoped drain. The results show that the SS and Ion/Ioff can be maintained below 10 mV/dec and beyond 105, respectively, when channel length is down to 3 nm.
Educational applications have become more and more popular, making a profound influence on education and teaching. In the "Internet+" era, it is a problem on how to design and choose a high quality and effective educational APP. Based on the Education Technology Developers Guide, 2016 annual online education user white paper and related scholars on the educational APP research, in this paper,...
The dramatic growth in the availability and capability of ICT has not only revolutionised the speed and the nature of global education, but also contributed to the regional differences in education informatization. This article makes a study, which sought to establish the existence or otherwise of digital divide with respect to the five dimensions of ICT in education in terms of development index...
Cloud computing and services have greatly changed the way how people develop and use software, and also raised a lot of new research issues. In this paper, we investigate two such important issues, service deployment and service request scheduling, for composite cloud services in dynamic cloud environments. We present load-aware service deployment approaches for dynamic workload and a service request...
Today, the development of vocational education has become countries go hand in hand that response to the crisis, promote employment, and meet the challenges of the new industrial revolution. Educational information is the important support. All levels of development planning has identified the importance of the development level of ICT, and clearly the relevant implementation measures. How to correctly...
The purpose of ICT in education is to support and lead the educational reform and development, so as to promote the realization of the educational modernization. Evaluation is the key to promote the sustainable development of education informatization. This paper aimed at establishing a evaluate model for the ICT development in basic education in a regional by the method of factor analysis. A large...
CMOS DRAMs which were first introduced commercially in the 256Kb DRAM generation have proven their advantages in power and performance, and are expected to be the future trend. In CMOS DRAMs, the half-VDD bitline sensing scheme — is widely used in the current generation of 1 Mb DRAMs. However, the half-VDD sensing scheme suffers a performance degradation as VDD is reduced. Starting with the 4 Mb DRAM...
A novel design of 2 × 2 NbN hot electron bolometer (HEB) mixer array receiver has been demonstrated here by using the multiple local oscillator (LO) beams obtained from a power distributor. In our design, the 1.5 THz LO beam is split into four uniform sub-beams with a spacing of 18 mm, then arrives at a four-pixel silicon lens with twin slot antenna (TSA) through a large-area beam splitter. An additional...
This paper describes the development of an inchworm robot. A new adhesion mechanism was inspired by the inchworm's behavior and empirically designed by using active shape control of suction cups. The equation of the motions of the robot are derived, and three gaits are developed. The robot is built and experimentally evaluated.
This paper investigates a novel packaging that can effectively improve the efficiency and reliability of 280-nm deep ultraviolet (DUV) light-emitting diodes (LEDs). The experimental results showed that use of a quartz airtight package dramatically improves light extraction efficiency compared with conventional silicone encapsulant under a rated current of 20 mA. The transmittance of silicone decreases...
Objective: To observe the nutritional support effects of calorie for senile chronic diseases. Methods: The 72 selected senile patients were divided into 2 groups, or the calorie restriction group and the non-calorie restriction group. Nutritional support was given by nasal feeding. The change of the nutritive index and the incidences of complications were observed in the 2 groups. Results: Hematochrome,...
Although ICT in basic education is developing rapidly in China over the last decades, the development of ICT adoption in different areas is unbalanced. Implementing district effectiveness evaluation is one of the necessary approaches to bridge the digital divide between developing and developed areas. Taking S city in China as an example, this paper uses a Principle Component Analysis model for district...
This research examines an assessment system that combines a mobile device with NFC (Near Field Communication) technology. Teachers attach or embed NFC tags into answer choices and students answer each question by bringing their mobile phone close to the answer that they think is the correct one. A four-week experiment shows that this assessment method takes more time than a traditional one. Also,...
According to the concept of combination weighting based on game theory, the combination of subjective weighting method (the analytic hierarchy process method) and objective weighting method (CRITIC method) integrate the advantages of both weighting methods. The paper used the combination of re-weighting method to calculate the index evaluation system of educational information and determine the impact...
Due to increasingly wide spreading applications of location-based services (LBS), a variety of portable devices are equipped with GPS module for navigation. If a notebook or ultrabook computer is embedded with a built-in GPS antenna and module, the EMI noise generated from SSD (Solid State Drive)/USB 3.0 module of the PC will radiate to affect the receiving performance of GPS antenna[1]. We have found...
This paper firstly builds a relational model between entrepreneurial attitudes and intentions of university graduates by literature review and surveys to entrepreneurs. Then a type of questionnaire is designed to survey graduate students in five regions of China. Finally, we extract data from the recycling questionnaires and build up regression model to find out the influences of entrepreneurial attitudes...
In nighttime video surveillance, proper illumination plays a key role for the image quality. For ordinary IR-illuminators with fixed intensity, faraway objects are often hard to identify due to insufficient illumination while nearby objects may suffer from over-exposure, resulting in image foreground/background of poor quality. In this paper we proposed a novel video summarization method which utilizes...
Construction project managers normally need develop their professional knowledge and practical skills in construction technologies and management on the basis of long term work experience. Their organizational commitment and job satisfaction level significantly influence their performance attitudes and job achievements. Keeping construction project managers highly committed to and satisfied with the...
Designing a high-quality assessment system is a challenge for college-level educators. An effective assessment system requires mastering the professional knowledge and skills involved. The field of assessment and evaluation has developed many important concepts, principles, and methods to guide practice. This study proposes an intelligent assessment management system for the summative assessment of...
A 220 GHz mixer chip based on a 3-junction series distributed superconducting mixer has been developed. This mixer employs a design, which minimizes the output capacitances, such that it can offer a wide instantaneous bandwidth of up to 12 GHz. We have incorporated this mixer into a receiver package and a dedicated automatic test bench has been developed to characterize its performance. The receiver...
