Eyes-open and eyes-closed are two physiological states with different levels of brain activity. To classify EEG in eyes-open and eyes-closed, limited penetrable visibility graph method is applied to analyze EEG. It is a signal process method based on graph theory, which bridges complex networks and EEG time series. Networks topology, average path length and clustering coefficient are used to depict...
In this paper, a nonsmooth dynamic filtering approach is proposed for stochastic noise filtering of mechanical servo-systems. In this approach, a stochastic nonsmooth state-space model with sandwich structure is developed to describe the nonsmooth dynamic feature of the system in random noisy case. Then, an approach for observability test of the nonsmooth system with sandwich architecture is proposed...
The Schur, respectively Hurwitz, diagonal stability of a complex interval matrix C relative to a Hölder p-norm, 1 ≤ p ≤ ∞, abbreviated as SDSp, respectively HDSp, is defined in terms of a matrix inequality using the respective norm. This approach generalizes the SDSp, respectively HDSp, of real interval matrices previously studied by the same authors; it also incorporates, for p = 2, the standard...
In this work, a physical non-linear model of an Electro-Hydraulic Actuator has been developed. Each system component (valves, pipes, cylinders) and their interactions have been modeled by means of conservation and constitutive laws. The actuator dynamics, with lumped-parameter element models, have been treated accurately, with special attention given to modeling friction. Finally, a global parametric-identification...
The concept of a virtual factory representation and its use to support data analytics in multiple ways in manufacturing environment are proposed. The proposed virtual factory when implemented can facilitate improvements in manufacturing operations through data analytics.
Article describes a method for determining the difference of adulterated and natural honey by spectral analysis. Features of the method are formulated. The technique of carrying out research, design of laboratory setup and the block diagram of a household appliance were developed. Spectral characteristics transmittance transmittances of the honey were received a result of an experimental study. Product...
The global stabilization of an eigenstate for finite dimensional stochastic quantum systems with non-diagonal free Hamiltonian and non-regular measurement operator is studied in this paper. A two-part switching control strategy is proposed, in which a constant control is used to steer the system state to enter the convergence domain; another control law, which is designed based on Lyapunov stability...
If it is desired to maintain performance of a linear model predictive control scheme in the face of changing operating conditions, then it becomes necessary to re-identify the dynamic prediction model intermittently. Recently, Patwardhan and Gopaluni [1] have proposed a novel reformulation of MPC which is capable of generating information rich input-output data while retaining the operation in the...
In this work we consider stability of singularly perturbed nonlinear systems affected by time-delays. In particular, we consider the case when trajectories of the boundary layer system of such a system converge to a compact set. By combining the averaging method and the Lyapunov-Razumikhin approach, we obtained sufficient conditions for semi-global and practical stability based on conditions of the...
In this paper, the driving cycle for electric cars in Beijing is investigated. Firstly a reasonable experimental scheme is made, in which several electric cars are selected and a new type of data collection transmission and management system based on GPRS communication is used. Then the obtained data is preprocessed and divided into mi-crotrips, and many characteristic parameters are selected. Finally,...
This paper proposes the implementation of an ancient Indian Vedic multiplier using the 16 bit modified carry select adder, 16 bit ripple carry adder and 16 bit kogge stone adder. The modified carry select adder shows the improved speed performance with less time delay. The design has been implemented using Verilog hardware description language. The design code is tested using the Modelsim simulator...
Cloud computing is evolving technology because of its reduced expenditure, maintenance and dynamic resource pooling provision, on demand service, virtualization & high availability. Security & privacy are the major issues in the cloud environment because of its distributed and open architecture. As Data is stored and delivered across the Internet. The owner has no knowledge of where this data...
Laboratory work and experimentation is the most important cornerstone in engineering education. However often times there are not resources enough in the laboratories of industrial automation, or enough time to apply the knowledge acquired in lectures. Therefore, it is necessary to have support systems that enable students to learn in an autonomous way and teach them in the management of physical...
This paper is about issues experienced along testing large-scale industrial products, with safety and security critical relevance. The challenges in testing - several thousand requirements for several product variants and various configurations - were addressed by test execution automation. However, since principal testing concepts as well as architectural concepts were ignored or poorly implemented,...
It is apparent that implementing Combinatorial (CT) Testing, being relatively new to many organizations, comes with both technical and non-technical challenges. This paper focuses the technical challenges and how they were addressed in implementing CT for solutions testing. The author believes that these challenges are not unique to solution testing, and that they are equally applicable to implementations...
Identification of an adequate invariant is valuable for reasoning about the correctness of code involving a loop, informally or formally. Almost every modern system for automated verification demands that programmers annotate their code with assertions, such as invariants to facilitate automation. But many learners struggle to grasp how to arrive at an assertion that remains an invariant and is sufficiently...
The power automation system, which can control almost everything that is powered by electricity in hospitals using live gesture recognition. In this proposed model the system uses a camera feed to detect the motion of hand, or any object. This movement of the object matched with the stored gestures to find the closest match and perform the corresponding actions associated with the gesture. This is...
The whole world has become faster than ever before. The demand and variety in consumer industry has increased phenomenally and is expected to further grow more. The market size is big and most production processes are also automated and have sufficient capacities. The manufacturers in competition are in a haste to launch newer and improved products but the product form development process is manual...
