The presence of parasite interference signals could cause serious problems in the registration of ECG signals and many works have been done to suppress these noise signals. By conducting a mathematical method based on varying window length as according to the distance from the adjacent Rpeak which are assumed to be high frequency noise (power line interference, electromyography noise) is removed with...
Trust has been a hotspot for adopting cloud computing. This paper proposes a hybrid model to build, evaluate and expose trust. It uses different techniques like sliding window technique to reach optimum processes for trust value delivery. Trust value is evaluated through integrated mechanisms from literature. Moreover, measuring trust included evaluating SLA violations side to side with consumer customized...
The great development in the area of evolutionary algorithms in recent decades has increased the range of applications of these tools and improved its performance in different fronts. In particular, the Differential Evolution (DE) algorithm has proven to be a simple and efficient optimizer in several contexts. Despite of its success, its performance is closely related to the choice of variation operators...
Cuckoo search is a swarm-intelligence-based algorithm that is very effective for solving highly nonlinear optimization problems. In this paper, the multiobjective cuckoo search is extended so as to obtain high-quality Pareto fronts more accurately for multiobjective optimization problems with complex constraints. The proposed approach uses a combination of the cuckoo search with non-dominated sorting...
Community structure has many practical applications, and identifying communities could help us to understand and exploit networks more effectively. Generally, real-world networks often have hierarchical structures with communities embedded within other communities. However, there are few effective methods can identify these structures. This paper proposes an algorithm HELPA to detect hierarchical...
Linking multiple data collections to create longitudinal data is an important research problem with multiple applications. Longitudinal data allows analysts to perform studies that would be unfeasible otherwise. In our research we are interested in linking historical census collections to create longitudinal data that would allow tracking people overtime. The goal of the linking is to identify the...
In order to acquire infrequent events as new ideas and evaluate the ideas quantitatively, it is necessary to know how people create and refine ideas and to model creating and refining process. In this paper, we focused on relations between thinking time and writing time in handwriting, and proposed to model the relation by externalization, classification, relation, transportation and systematization,...
In practical distributed storage networks, data centres house hundreds of racks, each of which contains several storage nodes. However, the majority of works in distributed storage assume a simple network model with a collection of identical storage nodes with same communication cost between the nodes. In this paper, we consider a more realistic rack model of storage network and present a code design...
S-system is a commonly used model for dynamic biological system. However, due to technical limitations, biological reaction networks are often only partially observable, which indicates that not all individuals incorporated in the model can be measured directly. Given a limited amount and quality of experimental data, it cannot be assured that the model structure and parameters can be estimated unambiguously...
The paper builds the influential factor model of virtual community knowledge sharing behavior from the four dimensions. By using structural equation model, the paper makes an empirical research on the key factors of promoting the college students' knowledge sharing behavior in the virtual community and the impact of knowledge sharing behavior of virtual community members on the community loyalty.
The change of ship's characteristic length can change scientific researching method. The paper gains the calculation parameters of Green function and the relational expression of vessels' characteristic length by establishing the analysis theory of ships' characteristic length dimension based on the control equation of green function and gives the statistical expression for ships' characteristic length...
As the sliding parameter of track is hard-to-measure when Agricultural Tracked Robot (ATR) is moving in complicated farmland environment, an estimation method for sliding parameters of ATR based on UKF is proposed. A kinematics equation and a measurement equation of ATR are deduced by kinematics principle, and then the precision position parameters of ATR is calculated. Sliding parameters which cannot...
This paper focuses on the modeling and simulation of silicon carbide(SiC) bipolar junction transistor(BJT). SiC BJT is modeled in MATLAB using internal dynamical equation, and the Haar wavelet method is used to solve the ambipolar diffusion equation (ADE). The simulation results of switching waveforms of SiC BJT are given, which verify the validity of this method.
This work presents the development of a motorized wheelchair controlled by cervical movements, where two accelerometers are used as sensors in the definition of movement commands of the wheelchair. One accelerometer is positioned in a helmet on the user's head and the second is positioned on chair base. The use of two sensors has the objective of collecting the signals in differential form providing...
Multilevel inverters are one of the most popular and useful type among all and have lots of usage like less disturbance and the possibility to function at higher switching frequencies than ordinary two-Level inverters. They can be used at different applications like electronic derivers, wind turbines and solar plants. In order to feed the DC current produced by PV panels to the inverters, power electronic...
In this work, we study the effect of in-phase soliton interaction with and without the effect of third order dispersion (TOD) in 100Gbps telecommunication system. The relative spacing of soliton is chosen as 5.28 (qo) and their interaction is noted in one collision period or length (Lcoll). The soliton interaction without TOD is noted with β2=−2.55ps2/Km and with TOD near Zero Dispersion (ZD) point...
P = {p,:i ∊ Nn}, Q = {qj, : j ∊ Nm}, R = {rk : k ∊ Nk} are considered as three referential sets and A ∊ R (P, Q;I), X ∊ R (Q, R; I), B ∊ R (P, R; I) are three fuzzy relations. We assume that these fuzzy relations are constrained to each other such that A o X = B. If two of the three components are known and other is to be calculated, then it is called fuzzy relation equation. When A and X are known,...
Semantic computing is an important task in the research of natural language processing.

Based on the in tensional logic model of Chinese concept connotation, using Recursive Conceptual Graph as knowledge representation method and combining with the computation...
In this paper, we consider the system of linear equations resulted from the elliptic PDE-constrained optimization distributed control problems. A new preconditioner is constructed and the preconditioned Generalized Minimum Residual (GMRES) method is applied to solve the linear system. Theoretical analysis and numerical experimental result show that the proposed preconditioned GMRES method is competitive...
This paper discusses the development of a public transit scheduling tool that can be run on a spreadsheet software. The main objective of the paper is to bridge the existing gap between the theoretical knowledge of bus service scheduling and local transport service providers in order for the latter to improve their service. Users of the tool are allowed to input onboard passenger counts, to analyze...
