Transfer functions and equivalent transformed structures of observed-based linear time-invariant control systems with the deterministic unmeasured disturbance have been found. They allow to simplify analysis of these systems. To determine the transfer functions used in formulas for the cell matrix.
Kinetics of a quantum system immersed in an equilibrium medium and completely described by its statistical operator is investigated. The case of a separable interaction is considered in details. A concept of the effective Hamilton operator of the system is discussed. The kinetic equation for a point particle in a spatially uniform external field placed in a medium of point particles is obtained in...
The advancements of Information and Communications Technologies (ICT) have contributed to an explosive growth of high-volume, high-velocity and high-variety information assets, and the era of Big Data has emerged. The infrastructure-based networks are becoming increasingly overloaded, while the cost of maintaining and expanding the infrastructure to accommodate the Big Data communications remains...
The main aim of this document is to verify the operation of the closed loop control for power converters through by HIL technical whose topologies are the buck, boost, and the buck-boost. This includes different signals properties, for example, input to the switching device (PWM), the response voltage and the current of the inductor. To develop objectives as mentioned, three main stages are raised:...
Both of the phase morphology and the thermal analysis revealed that the Phenoxy/P(BA-co-BT) and Phenoxy/PBA exhibited a homogeneous phase and a composition-dependent glass transition temperature (Tg), indicating the blends were miscible. The Phenoxy/PBT blends exhibited a heterogeneous phase and composition-independent Tg, indicating the blend was immiscible. Moreover, the result of thermal analysis...
This study was conducted to identify the relationship among some intrapersonal factors such as professional competency, interdisplinary ability, social skills capability, and team cohesion. The validated questionnaire was delivered to 296 students in the design programs of universities as research samples. Consequently, the SPSS 18.0 and AMOS statistic software were used to analyze the collected data...
In this paper a novel digitally programmable voltage mode (VM) quadrature oscillator (QO) employing DCVDGAs has been presented. The idea of DCVDGA is developed by inserting a digital control unit (DCU) with conventional VDGA The proposed oscillator configuration consists of two DCVDGAs along with three grounded passive components (two capacitors and one resistor) and offers following beneficial features:...
Resources in construction project are often limited, expensive, and scarce. Thus, allocating resources to project activities plays an important role in construction project management. Getting the shortest project duration sometimes is not necessary in a construction project because a construction project usually has a predefined project duration based on its contract. In the other hand, utilizing...
In many gas sensors, the selectivity is still a big issue, which makes the real concentration distortion. We introduce a way to estimate its concentration in gas mixture condition. The system consists of three gas sensors, carbon dioxide sensor, carbon monoxide sensor and humidity sensor in environment-controlled chamber, which give lots of different concentration combinations. To estimate its concentration,...
Commercially available light emitting diodes (LEDs) that have high efficiencies and long lifetime are offered in advanced packaging technologies. Many cooling systems were developed for current LED systems that enable a better removal of heat than counterpart devices offered earlier this decade. On the other hand, these lighting systems are still producing a considerable amount of heat that is still...
The ACG website for creative artifact work sharing supports artists at every level by offering a range of services to connect, inform, educate and promote digital artists worldwide together. A total of 347 digital multimedia design students majors related with ACG works from universities of north Taiwan served as research subjects. The findings of this study provided empirical evidence to support...
The Forward and inverse kinematics of the robot is the connection of mechanical system motion and control system. There is no closed form solution for inverse kinematics of 6 DOF robots currently. The method of numerical iterative algorithm is used usually, but which is hard to ensure the requirement of real-time and accuracy. Considering the application and characteristic of cobot, we designed the...
Representational state transfer (REST) is the current design standard for Web Application Programmable Interfaces (Web APIs or APIs). Unfortunately, existing Web API search engines allow for only keyword or tag-based searches for RESTful services without considering advanced functionality, such as contextual recommendation or visualization. In this paper, we propose a novel approach, referred to as...
Let h: ℤ+ → ℤ+ \ {1} be such that (1) h(n) ≤ lg n for all sufficiently large n and (2) h(n) and ⌈n1/h(n)⌉ are computable from n in O(h(n) · n1+1/h(n)) time. We show that given an n-point metric space (M,d), the problem of finding argmini∈M Σj∈Md(i,j) (breaking ties arbitrarily) has a deterministic, O(h(n) · n1+1/h(n))-time, O(n1+1/h(n))-query, (2h(n))-approximation and nonadaptive algorithm. Our derivations...
We consider a general class of stochastic optimization problems, in which the state represents a certain level or amount which can be partly used and depleted, and subsequently filled by a random amount. This is motivated by energy harvesting applications, in which one manages the amount of energy in a battery, but is also related to inventory models and queuing models. We propose a simple policy...
Cooperative sensing enables secondary users to combine individual sensing results in order to attain sensing accuracies beyond those achieved by consumer RF devices. However, due to sensing costs, secondary users may prefer not to cooperate to the sensing task, leading to higher false alarm probability. In this paper, we study how information about the presence of cooperators affects the dynamics...
The cylindrical parabolic waveguide is one of the waveguides whose modal spectra can be characterized quasi-analytically. The associated non-linear system of equations has already been accurately solved in the past, combining homotopy with shooting methods. However, a novel algorithm for bivariate problems has been found to be a good alternative for the root-finding process, allowing to solve all...
Given a current point, a final destination, and visiting data point categories on a trip, a sequenced route query finds the shortest route which meets the query condition. Several algorithms have been proposed targeting to this query. When this query is used in real applications, the popularity of the visiting points (for example, restaurant, shopping center, etc.) in a trip are also important besides...
The existing software release planning models aim to find a subset of software requirements with the highest value on the assumption that the value of a selected subset of requirements equals to the Accumulated Value (AV) of that subset. This assumption however, does not hold due to the Value-related Dependencies among software requirements. To address this, we have formulated an integer programming...
The aim of of this work is reduction of the in-band interference in the data obtained with the channel probe device in which the Frequency Modulated Continuous Wave (FMCW) signal is used. For this purpose, the minimum norm algorithm and Wiener filter applications were used. The results of examinations, by using more echoes of the channel profile, were compared and it was determined which method is...
