Neurocognitive response bias is a concern of clinical neuropsychologists, as accurate assessment is not possible if the patient being tested is not putting forth maximum effort during testing. Despite decades of research in this area, very little study has specifically examined the resilience of neuropsychological tests to incomplete effort. When college students asked to feign cognitive defici...

We investigate the strong stabilization of a wind turbine tower model in the plane of the turbine blades, which comprises a nonuniform SCOLE system and a two-mass drive-train model (with gearbox). The control input is the torque created by the electrical generator. Using a strong stabilization theorem for a class of impedance passive linear systems with bounded control and observation operators...

the present paper describes the designing of a thermally and economically optimum mechanical draft counter-flow wet cooling tower. the design model allows the use of a variety of packing materials in the cooling tower toward optimizing heat transfer. once the optimum packing type is chosen, a compact cooling tower with low fan power consumption is modelled within the known design variables. mor...

the goal of present study was to compare the performance of adhd and normal children on planning tests. 45 children with adhd aged between 7 to 12 were selected in mashhad city through convenience and randomized sampling. we used snap، cbcl، trf, csi-4 and clinical interview for diagnosis of adhd and put them into adhd-i, adhd-h, adhd-c subtypes. each subtype comprised 15 children with adhd. th...

Wind affects adversely the cooling tower thermal performance. A field investigation was carried out to study the thermal performance of Heller cooling towers under wind conditions, involving measurement of wind velocity and its direction around the cooling tower, and obtaining water flow rates and temperatures at the cooling tower inlet and outlet. Results show that air suction at the tower top...

We derive a model for a wind turbine tower in the plane of the turbine blades, which comprises an Euler–Bernoulli beam coupled with a nacelle (rigid body) and a two-mass drive-train model (with gearbox). This model has two possible control inputs: the torque created by the electrical generator and the force created by an electrically driven mass located in the nacelle. First, we consider the ca...
