NASA's Mars Exploration Rover (MER) Mission will place a total of 20 cameras (10 per rover) onto the surface in early 2004. Fourteen are designated as engineering and support operation vehicles on Martian surface. Images returned from also be significant importance to scientific community for investigative studies rock soil morphology. The Navigation (Navcams, two mast‐mounted stereo pair each with 45° square field view (FOV) an angular resolution 0.82 milliradians pixel (mrad/pixel). Hazard...
There is a growing body of evidence that higher-value information can be prioritised for both visual and auditory working memory. The present study examines whether valuable items similarly the tactile domain. Employing an immediate serial recall procedure (ISR), participants reconstructed 6-item sequence by moving their fingers in order original stimulation. Participants were informed either one position was worth notionally more points (prioritisation condition) or all equal value (control...
Background Overhead athletes are susceptible to shoulder injuries, among which rotator cuff injuries common and often directly associated with muscle weakness. Therefore, valid reliable measures of strength at sport specific positions may be a vital part sports physical therapy practice. Purpose: The current study aimed determine the inter- intra-tester reliability measuring internal rotation (IR) external (ER) novel testing position, 130° abduction compared 90°/90° position. A secondary aim...
Descent image motion estimation system is the first machine-vision for estimating lander velocity during planetary descent. Composed of sensors and software, DIMES features a descent imager, radar altimeter, an inertial-measurement unit, algorithm combining sensor measurements to estimate horizontal - speed across planet's surface travels as it descends. Although are not novel technology, flight software that combines them new. This radar, image, inertial data in way create low-cost, robust,...
Two experiments independently investigated the basis of chewing gum induced context‐dependent memory effect. At learning and/or recall, participants either chewed flavourless (Experiment 1) or received mint‐flavoured strips 2). No effect was found with strips, indicating that contexts were insufficiently salient to induce This is despite participants’ subjective ratings a perceived change in state following administration strips. Additionally, some preliminary evidence for non‐additive...
During the Mars Exploration Rover (MER) landings, descent image motion estimation system (DIMES) was used for horizontal velocity estimation. The DIMES algorithm combined measurements from a camera, radar altimeter, and an inertial measurement unit. To deal with large changes in scale orientation between images, altitude attitude to rectify images level ground plane. Feature selection tracking were employed rectified compute images. Differences of consecutive estimates then compared verify...
We describe an algorithm for navigation state estimation during planetary descent to enable precision landing. The automatically produces 2D-to-3D correspondences between images and a surface map 2D-to-2D through sequence of images. These are combined with inertial measurements in extended Kalman filter that estimates lander position, velocity attitude as well the time varying biases measurements. tightly couples camera resource-adaptive hence real-time capable fashion. Results from sounding...
The finding that chewing gum can moderate state anxiety under conditions of acute stress has proved difficult to replicate. present study examines the extent which social stress.
We examine the impact of chewing gum on a B akan‐type vigilance task that requires continual updating short‐term order memory. Forty participants completed 30‐min auditory akan‐task either with, or without, requirement to chew gum. Self‐rated measures mood were taken both pre‐ and post‐task. As expected, produced time‐dependent performance decrement indexed via decreases in target detections lengthened correct reaction times (RTs), reduction post‐task self‐rated alertness scores. The...
The present study examined the effect of chewing gum on sustained attention and associated changes in subjective alertness.In a within-participants design, 20 participants completed an extended version response task (SART: Robertson et al., 1997), both with without gum. Self-rated measures alertness, contentedness, calmness were taken before after SART.Chewing was improved attentional performance. This finding not contingent upon general decrease performance apparent at all stages task....
Aging is accompanied by changes in general cognitive functioning which may impact the learning rate of older adults; however, this often not controlled for aging studies. We investigated contribution differences rates to age-related landmark knowledge acquired from route learning. In Experiment 1 we used a standard procedure participants received fixed amount exposure route. Consistent with previous research, found deficits associative cue and sequence knowledge. 2 using flexible procedure....
Program to Optimize Simulated Trajectories II (POST2) is used as a basis for an end-to-end descent and landing trajectory simulation that essential in determining design integration capability system performance of the lunar environment models Autonomous Landing Hazard Avoidance Technology (ALHAT) project. The POST2 provides six degree-of-freedom necessary test, operate successful landing. This paper presents advances development model-implementation simulation, well preliminary analysis,...
Across two experiments we investigate the role of psychological distinctiveness on Hebb repetition effect. In direct contradiction to Horton et al. (2008), Experiment 1 demonstrated effect for inverted faces. Importantly, was evident only when filler and sequences comprised different items (no-stimulus-overlap) abolished trials same (full-stimulus-overlap). 2 further examined impact by comparing serial recall upright unfamiliar-faces, abstract matrices. We demonstrate visual stimuli that...
We examine serial order memory for sequences of tactile stimuli and investigate whether established characteristics memory, namely position effects, error distributions, Hebb repetition learning, are observed with memory. Visually obscured participants received six stimulations: one to each fingers. At test, lifted the fingers in stimulation. For every third trial same stimulation (i.e. sequence). Serial recall accuracy produced canonical bowed function found immediate recall. In addition,...
The mnemonic effect of posting personal experiences on ephemeral social media was examined. Participants completed a daily diary for 6 consecutive days. On alternate days they were instructed to use, or refrain from using, the platform Snapchat. At end week, participants received surprise memory test contents diaries. We observed significantly superior recall memories encoded Snapchat days, demonstrating facilitation despite type equivalency across and no conditions. study is first examine...
The present study demonstrates similarities between route learning and classical tests of serial order memory. Here, we investigated memory for landmarks in a task, younger older adults. We analysed data from task with 12 landmarks. Participants (88 77 older) learned using either Fixed Learning (3 exposures to the route) or Flexible (repeated until successful navigation was achieved) procedure. Following learning, participants completed Immediate Free Recall (IFR) Reconstruction Order (Free...
