As a consequence of changing immigration policy over the past 50 years, contemporary Australia has a culturally diverse population. Focusing on Brisbane, one of Australia’s smaller immigrant-receiving cities but where some 19 per cent of the population is born overseas, this study examines attitudes to and perceptions of culturally different ethnic (non-Anglo) immigrant groups. Emphasis is plac...

Traditionally, the automotive industry has been the largest employer of robots, but their control is inline and programmed to follow planning trajectories. In this case, in the motor's department test of Volskwagen México a semi autonomous robot is developed to generally purpose. Some critical technical problems must be solved in a number of areas, including in dynamics and control. Generally, ...

An attitude reconstruction algorithm has been developed for a flexible sounding rocket whose spin vector nutates unstably about its minor inertia axis. This algorithm deduces attitude for use in post-flight analysis of the sounding rocket's science data. An additional motive for pursuing this work has been to show that a flexible-body dynamic model can be used in a Kalman filter/smoother-type a...

It is well known that three momentum wheel actuators can be used to control the attitude of a rigid spacecraft and that arbitrary reorientation maneuvers of the spacecraft can be accomplished using smooth feedback. If failure of one of the momentum wheel actuators occurs, we demonstrate that two momentum wheel actuators can be used to control the attitude of a rigid spacecraft and that arbitrar...

An integrated coupled control strategy for a servicing spacecraft autonomously approaching and docking with a freely tumbling target is studied. To implement capturing successfully, the docking port of the servicing spacecraft should be always pointing to the docking port of target during close rendezvous and docking, which involves proximity maneuvering of coupled position and attitude simulta...

Pets’ growing role in family dynamics creates questions about resources pets may provide in parenthood motivation. Pet ownership has been suggested in the literature as an antecedent to parenthood in terms of developing skills needed to rear offspring, nurturance, and responsibility. Participants (N = 118) who were pet owners, completed an online survey that recorded demographics and consisted ...

For autonomous helicopter flight, it is common to separate the flight control problem into an innerloop that controls attitude and an outerloop that controls the trajectory of the helicopter. The outerloop generates attitude commands that orient the main rotor forces appropriately to generate required translational accelerations. Recent work in Neural Network based adaptive flight control may b...

1 Graduate Research Assistant, [email protected] 2 Assistant Professor, [email protected] Abstract For autonomous helicopters it is common to design a high-performance tracking controller for the attitude dynamics (innerloop) followed by a simpler, lower bandwidth design that tracks commanded position and velocity (outerloop). Separating these two designs places restrictions ...

Achieving success for ERP systems is not only concerned with deploying the technology on time and on budget but also concerned with the level of achieving targeted benefits from the system. This level of achieving targeted benefits can be managed indirectly through managing the organisational attitude toward the new system. Thus, the aim of this paper is to use the System Dynamics (SD) to revea...
