Low-loss photonic platform that can span the entire mid-infrared spectral region is reported based on the Ge-on-GaAs wafers. Optical loss of approximately 4.2 dB/cm is measured in ridge-waveguides at 10 μm wavelength.
In this paper, the U-slot is used to suppress the slotline mode of the right-angled coplanar waveguide bend. However, the power loss of the right-angled coplanar waveguide bend using the U-slot would be increased due to the radiation from the U-slot. In order to reduce the power loss, the right-angled coplanar waveguide bend using the finger slots are proposed. The right-angled coplanar waveguide...
A heuristic neural network (HNN) algorithm is proposed for pattern recognition. To achieve faster convergence and to promote the recognition accuracy, the proposed neural network is trained by adjusting the weighting values between layers, bias values of neurons and the learning rate according to the classification error. The whole architecture includes the image capturing by CCD camera, image pre-processing,...
We investigates a two-echelon supply chain with one risk-natural supplier and one loss-averse retailer where there is one short life cycles product with stochastic demand. The loss-averse preference is adopted to describe the retailer's decision-making behavior. We introduce a combined contract by organically combining the quantity flexibility contract and the buy-back contract with this issue. It...
This paper investigates a single-period two-echelon supply chain with random demand, where the loss-averse preference is adopted to describe the retailer's decision-making behavior. By combining the revenue sharing (RS) contract and the buy-back (BB) contract, a new combined contract is introduced. It is shown that the combined contract could mitigate the risk-aversion effect, and coordinate the supply...
A novel patch antenna consists of shorted-slots loading and asymmetric coplanar waveguide (ACPW) feeding structure is proposed in this article. The radiated patch antenna was chiseled two cross-slots, there are shorted-lines to be set at the middle- and cross-points of slots, which is designed to be operated at dual-ISM band (2.4GHz and 5.8 GHz bands). A prototype of the proposed antenna with 62 mm...
With the rapid development of information technology, the virtual world platform has become a competitive market due to its prosperous future. Since the number of both users and virtual products has grown rapidly, recommender systems have come to play an important role in the virtual world in terms of solving information overload problems and obtaining benefits for both platform runners and users...
Nowadays multimedia streaming is running on mobile devices under WiFi networks. To send the same media stream to multiple receivers, multicast is usually considered for efficient data transmission. Since multicast frames won't be acknowledged, it is difficult to evaluate the QoS of data delivery over WiFi. In this work, we proposed a so called Statistic Collection multicast scheme based on X-beacon...
An LED driver composed of a boost converter and dimmable current regulators with adaptive voltage feedback control (AVFC) is proposed. The AVFC is fulfilled with two diodes, one integrator, and one subtractor to sense the voltage variation among the current regulators and then to generate an adaptive reference voltage. According to the reference voltage, the output voltage of the boost converter is...
The Apache Hadoop software library has been a widely used framework for extremely large-scale reliable, scalable, and distributed computing. Previous researches pointed out that the shuffle phase can be the performance bottleneck of a MapReduce job because of network congestion in the Hadoop data center. To address this issue, the idea of introducing the Software-Defined Networking (SDN) technology...
Stock selection is an important issue when it comes to investing in the stock market. However, it is worth investigating the problem of selecting portfolios while considering not only low risk but also high return on investment. The calculation process of the traditional method is highly complex and is not comprehensive in terms of what it takes into consideration. Hence, this paper proposes a new...
The smart meter is an emerging appliance which can be used to collect and monitor the power consumption data on electrical devices. Users can monitor these devices in order to adjust their operations for energy saving results. To avoid wasting power, it is important to set a power usage constraint to effectively monitor and control users' power consumption within a restricted power usage range. However,...
With the emerging of social network websites, more and more social network online games are booming. Players have more alternatives of VWs games, while platform providers suffer from the problems of high customer turnover rate and low-customer-loyalty. Therefore, building a churn prediction model to facilitate subsequent churn management and customer retention is the best core marketing strategy....
In order to develop the next generation of gaze tracking system that can operate under visible lighting conditions, the difficulty of estimating limbus circle in real time needs to be solved. The iris model-based approaches excel the feature-based ones, but high computation complexity remains a problem. This paper presents an advanced iris model-based matching algorithm which adopts particle swarm...
To reduce the manpower and response time for surveillance systems at low cost, in this paper, an ARM-based embedded system dedicated for unattended realtime moving target detection is constructed. The comprehensive procedures in building up an embedded system such as setup environment for cross-compilation, migration of Bootloader, migration of Linux-2.6 kernel, fabrication and migration of root document...
Curcumin holds great therapeutic potential and has been a molecule of interest for many years, as it exhibits activity against a wide range of diseases, with no known toxicity. Curcumin has anticancer, anti‐inflammatory, antioxidant, antiviral, and anti‐malarial activity, and these are reviewed in this chapter. Gossypol 1 exhibits atropisomerism, a form of stereoisomerism known as axial chirality,...
Some cell-internal defects can be modeled as small delay faults. This paper presents a timing-aware gate exhaustive transition fault (TARGET) ATPG for cell-internal defects. Our ATPG tries to launch gate output transitions from as many different gate input transitions as possible. We defined TARGET coverage and TARGET SDQL to evaluate the quality of our test sets. TARGET does not require exhaustive...
The purpose of the study was to develop a flash-based animation program to prevent the relapse of illicit drug use among the adolescents who had ever used illicit drugs. We designed 13 flash animations which emphasized on life skills related to illicit-drug-use prevention, including refusal skills, stress coping, problem identifying and solving, etc. The pre-post changes of life skills and using illicit...
Low breakdown voltage in deep-submicron CMOS devices has limited the supply voltage and output power of power amplifiers (PAs). In this paper, a differential cascode Class-E PA in 65nm CMOS is proposed. Using only the standard devices, the stacked-cascode structure can endure a maximum voltage up to 10V so that a supply voltage of 3.3V is possible for Class-E PA. An auxiliary branch is added to reduce...
This paper presents a multivariable self-tuning proportional-integral-derivative (PID) controller based on wavelet fuzzy neural networks (WFNNs) for a class of nonlinear systems. A mathematic model using WFNN is constructed for the controlled nonlinear multivariable system, and the self-tuning PID controller is derived via a generalized predictive performance criterion. Numerical simulations exhibit...
