This paper summarises the current state of the art and future intentions for deconfliction of civil aircraft. The paper then describes the relationship between Pilot and Controller to ensure the safe navigation of all aircraft operating in the same airspace. The paper focuses on 4D profile prediction and its use for what is known in Civil Aviation as Medium Term Conflict Detection/Alert. The pa...

An ecological pilot project for the control of Triatoma dimidiata allowed a new evaluation four and five years after environmental modifications in the peridomestic areas of 20 households. It was verified that the two groups of houses, 10 case-houses and 10 control-houses, were free of insects after those periods of time. In the first group, the owners started a chicken coop in the backyard and...

Modelling and simulation of semi-autogenous (SAG) mills are valuable tools for helping to design control laws for a given application and subsequently to optimise its performance and process control. SAG mills (see Figure 1) are presently one of the most widely used alternatives in the field of mineral size reduction as a result of their advantages such as higher processing capacity, lower phys...

BACKGROUND Methods for error analysis are suitable to increase patients' safety as well as staff satisfaction and may avoid, in a sense of process control, financial damage to the hospital. The aim of the presented pilot study was to establish and evaluate an incident reporting system as a first step towards a new safety culture. METHODS In June 2003 an incident reporting system was introduce...

This case examines issues in the assessment and adoption of Internet technologies in a federal U.S. government context, and describes in detail a pilot project to determine the feasibility of adopting an ASP solution to support procurement by multiple federal agencies using a variety of different legacy transaction systems. The pilot test of the Internet Payment Platform (IPP) by the eMoney gro...

This paper describes a channel estimation and tracking scheme for OFDM MIMO systems based on pilot tones. The mean square error of the proposed scheme is derived, and through this we derive optimal training sequences and placement of the pilot tones. It is shown in this paper that minimum mean square (MMSE) channel estimation is obtained with equipowered, equispaced, orthogonal and phase shift ...

The Traffic alert and Collision Avoidance System (TCAS) is often framed as separate to -or opposing -air traffic control, i.e. as a backup, redundant system that invokes resolution advisories (RAs) when all other methods of separation assurance fail. A flight simulator experiment examined pilot interaction with TCAS in the context of a full air traffic environment. This paper will describe how ...

objective: to evaluate the effect of meperidine, commonly administered for labor analgesia, on newborn weight and peripartum breastfeeding during two months after delivery. materials and methods: this pilot cohort study was conducted between october 2010 and october 2011 at the women hospital of the tehran university of medical sciences. in this study, we examined the effects of meperidine on b...
