Facial landmark detection, as a typical and crucial task in computer vision, is widely used in face recognition, face animation, facial expression analysis, etc. In the past decades, many efforts are devoted to designing robust facial landmark detection algorithms. However, it remains a challenging task due to extreme poses, exaggerated facial expression, unconstrained illumination, etc. In this work,...
The goal of this research is developing a multimrdia based mobile application, specially a mathematics mobile game for elementary school. This learning model should encourage student's ability to learn mathematics particularly numbers. This research consists of seven steps according to Borg & Gall named Research & Development, such as research and preliminary information collecting, planning,...
The paper is devoted to application of the novel 2DOF Quadrotor-based Laboratory Testbed for engineering education in the such the disciplines as Automatic Control, Adaptation and Identification, Real-time Control Systems, Data and Signal Processing, Telecommunications, Information Theory, Flight Dynamics, high- and low-level Programming Languages. The testbed is based on a quadrotor, mounted in the...
As the main contribution of the paper, we present a network of electro-mechanical systems as a suitable platform for education, testing and verification of real-life implementation of decentralised and distributed control solutions. The overall system (network) consists of a set of elastically interconnected seesaw-chart systems. Additionally, suitable, control oriented, structured model of the system's...
This paper proposes a trading strategy based on a learning method to combine a set of technical trading signals. The learning employs a modified Particle Swarm Optimization to optimize the weights of signals. The set of weighted signals is then used to determine trading decisions, i.e. to buy, to sell or to hold. A trading simulation is conducted using historical daily stock prices of twenty stocks...
Credit scoring is an important process in every financial institution and bank. Its high accuracy in classifying customers helps decrease the credit risk and increase reliability and profit. In this paper, we propose a binary classification approach that can classify customers who apply for loans. A statistical technique called Stepwise Regression (SR) is used as a pre-process to select important...
We prove that the solvability of systems of linear equations and related linear algebraic properties are definable in a fragment of fixed-point logic with counting that only allows polylogarithmically many iterations of the fixed-point operators. This enables us to separate the descriptive complexity of solving linear equations from full fixed-point logic with counting by logical means. As an application...
The paper presents a real-time (RT) model implementation of a power flow controller device called Dynamic Power Flow Controller (DPFC). The RT model is developed in a RT simulator (RTS) from OPAL-RT Technologies Inc. and designed with reference to a hardware DPFC model developed at the Institute of Energy Systems, Energy Efficiency and Energy Economics (ie3), TU Dortmund University, Germany. The DPFC...
Considerable wind resources are aggregated on Taiwan west coasts that adjacent to Taiwan Strait, it promotes the domestic government to develop the off-shore wind farms for the applications of renewable energy. The first MW level wind turbine testing site that be connected to the 11.4 kV distribution system is also under construction in Taiwan, which is expected to provide testing and certification...
With the advent of large data age, the recommendation system began to enter people's lives, according to the user's habits, how to recommend will become the future business development trend. In this paper, we used Elaboration Likelihood Model (ELM) to demonstrate the important adoption factors on the recommendation system such as the recommendation persuasiveness, recommendation source credibility,...
The test case generation of Cyber-Physical Systems (CPSs) face critical challenges that traditional methods such as Model-Based Testing cannot deal with. As a result, simulation-based testing is one of the most commonly used techniques for testing CPSs despite sometimes being computationally too expensive. This paper proposes a search-based approach which is implemented on top of Non-dominated Sorting...
As embedded systems become increasingly complex, there is a great need to equip engineering students with the knowledge of advanced embedded software development techniques so as to improve their efficiency in software development and programming. This paper presents our experiences of introducing the model-based design (MBD) methodology to two computer engineering related undergraduate courses: Programming...
In this work, we present a parameter extraction method for TiO2 memristive devices that applies on a resistive switching rate model which embodies only four parameters for each voltage biasing polarity. The simple form of the model functions allows the derivation of a predictive analytical resistive state response expression under constant bias voltage. By employing corresponding experimental testing...
An elastic viscous plastic mechano-rheological model was developed for theoretical analysis of a spherical body shock interaction with a surface. The influence of the model elastic viscous plastic parameters on the dynamic parameters of a shock process was analyzed. The obtained results served as the basis for development of a new patented shock method to calculate the elasticity modulus. Some tests...
In the increasingly fierce competition of the colleges and universities, how to improve the teaching quality and enhance the competitiveness has become an important issue to every colleges and universities. Universities are trying to build scientific and perfect ideological and political classroom teaching quality evaluation system. AHP (Analytic Hierarchy Process) is based on the combination of quantitative...
This paper presents a mathematical model for assessing the availability of a non-redundant telecommunications system, which is continuously tested during operation. The types of faults that can occur in such systems are defined as permanent and intermittent faults. Mathematical equations are derived to calculate the mean times spent by the system in the operable and repair states using the properties...
The importance of the mechanical behavior of electronic packages starts at the beginning of the package assembly process and continues through performance testing procedures at different levels. Predicting an electronic package's mechanical performance by simulation is an ongoing challenge and pursuit of both industry and academia. To achieve this goal, advanced simulation or analyses should have...
The trend towards multi-die flip chip packaging favors the incorporation of a qualified manufacturingcompatible rework process to remove and replace individual defective die. Inherent to the rework process is an electrical verification step that effectively identifies the defective device without compromising the integrity of an otherwise perfectly functional device. Unfortunately, the very feature...
This paper describes a traffic system, the model simulation is intended to explore the influence caused by BRT with autonomous control of traffic lights on the traffic of urban main roads.
Many areas of robotics, particularly locomotion and grasping, can benefit from the ability to modulate friction on surfaces that come into contact with objects in the environment. Previous research has tried to address the challenge of tunable friction; however, those efforts only provide modest gains or are difficult to integrate. We propose a tunable friction mechanism that relies on pneumatic actuation...
