In this paper, an Adaptive Feedback Framework (AFF) is proposed for the provision of personalized feedback accommodating learners’ individual characteristics and needs in the context of computer-based learning environments. Multiple Informative, Tutoring and Reflective Feedback Components (ITRFC) are incorporated into the framework, aiming to stimulate learners to reflect on their beliefs, to g...

Spontaneous rupture of uterine vessels, though rare, is a life threatening condition occurring during pregnancy or the peripartum period. The maternal and perinatal mortality may be as high as 40 and 30 % respectively [1]. Though more than 100 cases of rupture of uterine vessels have been reported during pregnancy and puerperium, only five cases have been reported during labor [2]. The case und...

-The input feedforward path in a ΔΣ modulator is an attractive technique for low-distortion swing-reduction design. It helps lower the power dissipation, especially in ΔΣ modulators designed with low oversampling ratios (OSRs) in low-voltage nanometer CMOS technologies. However, a ΔΣ modulator with analog feedforward (AFF) requires an analog adder before the quantizer, which can limit the achie...

The objective of this study was to assess the adsorption potential of activated carbon (AC) asan adsorbent for the removal of Murexide (Mu) from aqueous solutions. The influence of variablesparameters including pH, amount of adsorbent, sieve size of adsorbent, temperature and contact timeon Mu removal was studied. Following optimization of variables, the relation between concentrations ofdye re...

in this paper, we deal to obtain some new complexity results for solving semidefinite optimization (sdo) problem by interior-point methods (ipms). we define a new proximity function for the sdo by a new kernel function. furthermore we formulate an algorithm for a primal dual interior-point method (ipm) for the sdo by using the proximity function and give its complexity analysis, and then we sho...

this paper aims to investigate a new and intricate behavior of immediate follower during the lane change of leader vehicle. accordingly, the mentioned situation is a transient state in car following behavior during which the follower vehicle considerably deviates from conventional car following models for a limited time, which is a complex state including lateral and longitudinal movement simul...

in previous papers authors have considered agents as inertia-less self driven particles and designed a flocking algorithm. application of this algorithm to agents with considerable inertial characteristics needs a behavioural controller. the controller uses the local information and helps every agent to imitate the desired behaviour as a member of the flocking frame which covers the main issue ...

car-following models, as the most popular microscopic traffic flow modeling, is increasingly being used by transportation experts to evaluate new intelligent transportation system (its) applications. a number of factors including individual differences of age, gender, and risk-taking behavior, have been found to influence car-following behavior. this paper presents a novel idea to calculate the...

For discrete-time scalar systems, we propose an approach for designing feedback controllers of )xed order to minimize an upper bound on the peak magnitude of the tracking error to a given command input. The work makes use of linear programming to design over a class of closed-loop systems recently proposed for the rejection of non-zero initial conditions and bounded disturbances. We incorporate...
