Determining Direction‐of‐Arrival Accuracy for Installed Antennas by Postprocessing of Far‐Field Data

Abstract: Direction‐of‐arrival (DoA) estimation accuracy can be degraded due to installation effects, such as platform reflections, diffraction from metal edges, and reflections and refraction in the radome. ...

Means for exposing normally covered plate while moving it to exposure situation

Abstract: A specimen plate having a lengthwise slidable cover is placed on a carriage to move therewith into and out of an isolation chamber. A cover holder, movable in and out both relative to the carriage and with it, detachably retains the cover and prevents it from moving with the carriage beyond predetermined limits, so that the specimen plate is slid out of the cover and exposed while moving into the isolation chamber with the carriage, and is slid back into the cover as it is moved out of the isolation chamber.

Elements of team effectiveness: A qualitative study with pilots

Abstract: Fighter pilots performing air missions rely heavily on teamwork for successful outcomes. Designing systems that support such teamwork in highly dynamic missions is a challenging task, and to the best of our knowledge, current teamwork models are not specifically adapted for this domain. This paper presents a model of task performance for military fighter pilots based on the teamwork model “Big Five” proposed by Salas, Sims, and Burke [1]. The “Big Five” model consists of eight teamwork elements that are essential for successful team performance. In-depth interviews were performed with fighter pilots to explore and describe the teamwork elements for the fighter aircraft domain. The findings from these interviews are used to suggest where in the task cycle of mission performance each teamwork element comes in to play.

Dedicated measurement campaign for definition of accurate reference pattern of the VAST12 antenna

Abstract: In this paper, three possible approaches for definition of a highly accurate reference pattern of a reference antenna are described and their pros and contras are discussed. Following the most reliable approach, a dedicated measurement campaign was planned and carried out in 2007-2008 for definition of the highly accurate reference pattern of the VAST12 antenna. In planning the campaign, conclusions from the first comparison campaign with the VAST12 carried out within the ACE network in 2004-2005 were taken into account and these are also presented and discussed. Some typical measurement errors and uncertainties are listed and briefly discussed.

Arrangement for preventing bearing-related noise in internal combustion engines

Abstract: Internal combustion engine with variable compression, comprising a crankshaft-bearing crankcase part (2) and a cylinder-receiving part (6) arranged tiltably thereon by means of a tilt axle bearing (8) on one side of the engine and a tilt mechanism (10) on the other, opposite side of the engine, which cylinder-receiving part (6) supports a cylinder head (14) which is securely connected thereto, preferably with camshafts mounted therein. Arranged between the crankcase part (2) and the cylinder-receiving part (6) there are prestressing members (38) which force these engine parts apart and work to counteract the occurrence of bearing play in the tilt axle bearing (8) and in the tilt mechanism (10) when compression-modifying tilting movement between the cylinder-receiving part (6) and the crankcase part (2) occurs during running of the engine.
