This review paper is concerned with the development of physiological computing systems that employ real-time measures of psychophysiology to communicate the psychological state of the user to an adaptive system. It is argued that physiological computing has enormous potential to innovate human– computer interaction by extending the communication bandwidth to enable the development of ‘smart’ te...

This paper provides a critical review to analyze the promises and important challenges of studying flow, a psychological state, in the computer-mediated environments (CME). Despite the strong interest in IS, HCI, Marketing, Education, and other research disciplines over more than a decade, adapting the phenomenon of flow to computer users shows high inconsistencies and discrepancies in the lite...

Biosignals, peripheral or from the brain, can be used to recognize mental states. Subsequently, these signals can be employed to enhance user experiences. This paper identifies challenges that have to be faced with processing such signals and defines guidelines to tackle them. We pose that these guidelines can initialize a leap forward in the development of real-time biosignaldriven adaptive sy...

We study the convergence of finite-capacity open queueing systems to their infinite-capacity counterparts as the capacity increases. Convergence of the transient behavior is easily established in great generality provided that the finite-capacity system can be identified with the infinitecapacity system up to the first time that the capacity is exceeded. Convergence of steady-state distribution...

Estimation of the channel impulse responses of multiple cochannel users is a key requirement of all multiuser detection and interference cancellation techniques, though little attention has been paid to subject in the context of TDMA systems. This paper addresses a pilotbased technique for multiuser channel estimation in a TDMA system, and makes several new contributions: it allows for time var...

objective(s): it has been suggested that the efficiency of dry poder inhaler (dpi) is generally low. therefore, the aim of the present research work was to use the solvent treatment of the carrier in dpiformulations to see the possibility of inducing desirable characteristics.   materials and methods: lactose sieve fractions of 63-90 μm were submerged in ethanol or 80% v/v ethanol, methanol or ...

We study the ground-state properties of kinetic-exchange models for ~III,Mn!V semiconductors with randomly distributed Mn ions. Our method is embedded in a path integral spin-wave-type formalism leading to an effective action for Mn spins only with full Matsubara frequency dependence. The zero-frequency contribution to this action is equivalent to static perturbation theory and characterizes th...

In a recent comment, it has been shown that in a quantum secret sharing protocol proposed in [S. Bagherinezhad, V. Karimipour, Phys. Rev. A, 67, 044302, (2003)], one of the receivers can cheat by splitting the entanglement of the carrier and intercepting the secret, without being detected. In this reply we show that a simple modification of the protocol prevents the receivers from this kind of ...
