A survey was conducted on 210 Baby Boomers (Age mean = 51.4 Std. dev. 5.46) within the United States to determine their current use of online technology in social interactions, their preferences in these interactions, and the expectations they have of near-future online communication technologies. The findings highlight the importance of online communication in their lives and spotlight their w...

We present a simple procedure to construct non-local conserved charges for classical open strings on coset spaces. This is done by including suitable reflection matrices on the classical transfer matrix. The reflection matrices must obey certain conditions for the charges to be conserved and in involution. We then study bosonic open strings on AdS5×S. We consider boundary conditions correspondi...

We propose a new protocol providing cryptographically secure authentication to unaided humans against passive adversaries. We also propose a new generic passive attack on human identification protocols. The attack is an application of Coppersmith’s baby-step giantstep algorithm on human identification protcols. Under this attack, the achievable security of some of the best candidates for human ...

According to the Dual-Mode theory, the two different dynamic components seen in the step response of disparity vergence eye movements are under separate control mechanisms. The initial, fast rising component is controlled by an open loop, preprogrammed system while the later, slow component is feedback controlled. The ability to separate the two components, or to isolate the initial component, ...

In this paper, a self-tuning fuzzy controller with a smart and easy structure is presented. The tuning schemes allow us to tune the scaling factors by only seven rules. The aim of a controller is to obtain a satisfactory performance, such as the rise time, the overshoot, the steady-state error for the step response. Simulation results of a third order system with time-delay show a better perfor...

One of the main elements of a cryogenic (C) separation column is the boiler. The control of the power supply which feeds the boiler’s resistance is of major importance. In order to ensure a safe and stable operation of the plant, a monitoring and control unit is designed using NI PXI-8183 process computer. The developed LabVIEW application implements a PI controller and also data logging. Step ...

The paper describes the identification of the variable critical gain and natural frequency of the pneumatic cylinder using the self-excited oscillations method. The pneumatic drives are characterized by the low stiffness of the pneumatic cylinder which depends on the piston position and determines the natural frequency of the cylinder. The variety of the stiffness in dependence on the piston po...

In this paper, a new approach is proposed to model and control the temperature of a thermal barrel of a plastic molding machine. Usually the thermal barrel behavior is expressed in terms of a parameterized linear model to be used in control strategies design. We establish a new model based on the structure of a Takagi-Sugeno fuzzy system, and utilize the clustering method to generate the rule b...

Most of the proportional-integral-derivative (PID) controller tuning methods reported in literature are based on the approximate plant models (FOPDT or SOPDT models) derived from the step response of the plant. In this paper, a new method of designing PID controllers using ‘impulse response’ instead of ‘step response’ of the plant is presented. Treating the impulse response of the plant as a st...
