This article prospectively explores the effects of collective team work engagement and organizational constraints during military deployment on individual-level psychological outcomes afterwards. Participants were 971 Dutch peacekeepers within 93 teams who were deployed between the end of 2008 and beginning of 2010, for an average of 4 months,...

The Triangle Orientation Discrimination (TOD) test method was applied to characterize thermal and visual range performance of the Gatekeeper Electro Optical Security System. Gatekeeper developed by Thales Nederland BV, is currently in use with the Royal Netherlands Navy. The system houses uncooled infrared and colour TV cameras providing up to...

Night vision equipment is crucial in order to accomplish supremacy and safety of the troops on the battlefield. Evidently, system integrators, MODs and end-users need access to reliable quantitative characterization of the expected field performance when using night vision equipment. The Image Intensifier tube is one of the most important...

Military deployment in theaters of war, like Iraq or Afghanistan, may cause considerable psychosocial disturbances in any given soldier. These symptoms may develop over time into full blown—deployment related—psychopathology, with severe consequences, not only for the individual involved but for their families, colleagues, friends, and society...

We investigated whether manipulation of visual and auditory depth and speed cues can affect a user’s sense of risk for a low-cost nonimmersive virtual environment (VE) representing a highway environment with traffic incidents. The VE is currently used in an examination program to assess procedural knowledge of highway patrol officers. In its...

We investigate how human visual search performance with field of view (FOV) restrictions depends on scan speed, zoom factor, target location, and conspicuity. First, observers search a FOV that moves at a constant speed along a predefined path over a visual search scene (the field of regard, or FOR), and we measure the effects of scan speed,...

Search and detection are two everyday jobs of many biological systems, performed almost innately, either consciously or subconsciously and necessary for survival. Search and target detection, in particular, are the first stages in visual observation tasks associated with military target acquisition, industrial inspection, traffic control, and...

We present a new method to derive a multiscale urban camouflage pattern from a given set of background image samples. We applied this method to design a camouflage pattern for a given (semi-arid) urban environment. We performed a human visual search experiment and a computational evaluation study to assess the effectiveness of this multiscale...

This paper presents and discusses experimental designs, measures, and measurement methods for determining the effectiveness of training simulators. First, we describe experimental designs in which training effects of training simulators are compared to those of conventional training. Next, the most commonly used metrics for quantifying the...

Using a cross-sectional design, this study explored operational demands during the International Security Assistance Force for Afghanistan (2009-2010) across distinct military units. A total of 1,413 Dutch soldiers, nested within four types of units (i.e., combat, combat support, service support, and command support units) filled out a 23-item...

The defense is confronted with a high competition on the labor market and a substantial scarcity of personnel. If we are able to enhance and maintain resilience and performance of personnel by proper selection procedures or mental training we expect to increase the return on investment of military education, training and operation, that is:...

The MRTD and MRC end-to-end EO/IR system tests and corresponding models, described in NATO STANAGs 4347-4351, lead to incorrect Target Acquisition (TA) range predictions for modern imaging systems that are 1) usually under-sampled and/or 2) contain complex signal processing. Considerable efforts have been made to develop tests and models that...

Within the EU FP7 project SILENV, noise and vibration measurements were carried out on several ships. These objective measures were accompanied by subjective measures recorded through questionnaires. With this, we developed models describing the relationship between the levels of noise and vibration on board ships and subjective ratings on...

Het onderhavige rapport biedt een overzicht en evaluatie van het door TNO uitgevoerde onderzoek in het kader van het programma Effectieve Opleiding en Training (V801). Dit programma was gericht op het uitbreiden van de kennisbasis met visies, concepten en methoden, die de krijgsmachtdelen in staat stelt effectief in te spelen op in- en externe...

We present the design and evaluation of a new demonstrator rifle sight viewing system containing direct view, red aim point and fusion of an (uncooled, LWIR) thermal sensor with a digital image intensifier. Our goal is to create a system that performs well under a wide variety of (weather) conditions during daytime and nighttime and combines the...

De publicatie is een combinatie van de resultaten van TNO projecten over crisiscommunicatie en zelfredzaameheid van burgers. Wat doe je als er in je omgeving iets gebeurt? Een overstroming, een opstootje of een ongeluk? Of als de stroom langdurig uitvalt, gas of water afgesloten raken in een strenge winter? En wat als er in je huis of kantoor...

Both bio- and neurofeedback (training) protocols are hypothesized to be beneficial in the management of arousal states and psychological recuperation after aversive and potentially traumatic experiences. As military deployments in theatres like Iraq or Afghanistan imply an significant risk for potentially traumatic experiences and stress related...
