This paper deals with the leader-follower formation control problem while communication constraint in data transmitting is considered. From a practical point of view, we study the case in which unmanned vehicles are subject to the limited sensing, and communication is of a particular interest. A three-dimensional formation flight of multi-unmanned aerial vehicles with leader-follower configurat...

We address the development of software devices that can be installed on groupware systems to help people stay attentive and be more productive during computer-mediated collaboration. We introduce a framework that derives attentive devices from groupware mediation modes to take into account attentional phenomena, and demonstrate the framework’s role in an attentive electronic brainstorming tool....

The system of asylum seeker detention in Australia is one in which those seeking refuge are stripped of many of their rights, including the right to health. This presents serious ethical problems for healthcare providers working within this system. In this article we describe asylum seeker detention and analyse the role of nurses. We discuss how far an "ethics of care" and witnessing the suffer...

This paper provides a management overview of a new joint Navy/Army millimeter wave (MMW) seeker technology development initiative. The goal of the program is to provide advanced seeker components for endoatmospheric interceptors for theater and strategic missile defense. The technologies are driven by requirements for low weight/volume interceptors, high interceptor and target velocities and a ...

Recently, the IBM Institute for Knowledge-Based Organizations (IKO) studied the role of trust in knowledge sharing. Factors such as the strength of the relationship between the knowledge seeker and the knowledge source, the difference between competence-based and benevolence-based trust and the type of knowledge being exchanged were explored. Data from a two-part survey of 138 people in three c...

The tomographic scanning (TOSCA) imaging seeker concept is presented. The system is based on conical scan reticle seeker optics modified with an eccentrically rotating circular aperture. After signal preprocessing, an image is extracted using tomography reconstruction techniques. Simulation results are provided to show the reconstruction quality. The concept, using a single pixel and a simple r...

The majority of homing guided missiles use gimbaled seekers. The equations describing seeker gimbal system are highly nonlinear. Accurate nonlinear control of the motion of the gimbaled seeker through the attached DC motors is required. In this paper, an online technique for finite-horizon nonlinear tracking problems is presented. The idea of the proposed technique is the change of variables th...

This paper presents a seeker algorithm for solving the multi-objective reactive power dispatch problem. Swarm intelligence algorithms have been productively applied to hard optimization problems. Seeker optimization algorithm is one of the latest members of that class of metaheuristics and the primary type of this algorithm was less successful with multimodal functions. We propose hybridization...

Missile pose estimation in terminal guidance refers to the technique of estimating missile position and attitude by matching seeker images with pre stored reference images during the terminal phase of missile flight. This paper presents a method for estimating the position and orientation of the missile with respect to a known object using point correspondences between seeker and reference imag...
