 | A model of team collaboration was empirically evaluated by applying definitions of the macrocognitive processes included in the model to the team communications that transpired during two real-world decision-making domains. Macrocognition is defined as the internalized and externalized high-level mental processes employed by teams to create new knowledge during complex, one-of-a-kind problem solving. Team collaboration during two unique, information-rich, time-compressed situations was analyzed and coded, using verbatim transcripts or chat ... |

|
| This 7-month-long project quantifies the role of brain rhythms in speech perception by measuring intelligibility of spoken sentences with judiciously manipulated changes in syllabic rhythm. Speech was time-compressed by a factor of three, resulting in a signal with a syllabic rate three times faster than the original and with poor intelligibility (< 50% words correct). An artificial "syllabic" rate was then introduced by segmenting the time-compressed speech signal into consecutive ... |

|
| Network Centric Warfare (NCW) as an emerging concept promises increased battle space awareness through information management. To the Operational Commander the potential for increased data collection and opportunities to capitalize on enemy information vulnerabilities provides greater opportunities for victory. The concept of Network Centric Warfare when coupled with technological advances and innovations will provide advantages through the Operational Planning Functions that will need to be considered during Joint Warfare planning. ... |

| The revolution occurring in the United States stock market has leveraged technological enhancements and brought about changes in the fundamental way business is conducted. Adaptations of enhanced systems and lessons learned from that revolution lend themselves for direct application to the concept of Network Centric Warfare. Successfully adapting those advances will therefore be the enabler through which we will use NCW to leverage shared ... |

|
| The research requirement is to develop a user's manual for the longitudinal database of gunnery-related information used to assess the impact of Project SIMITAR's (Simulation in Training for Advanced Readiness) time- compressed gunnery training strategy for ARNG armored and mechanized infantry units (Smith, in publication). This user's manual describes how the SIMITAR database is structured to support longitudinal tracking of live-fire gunnery performance measures and related information necessary for assessing ... |

| Training in Commercial Logistics Practices to Improve Inventory Management in the Navy |

David J. Randle; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| The Department of Defense (DoD) has repeatedly been accused of needlessly holding large inventories. In comparison, the commercial sector has drastically cut its inventories over the last twenty years through such practices as Just-In-Time (JIT) and cycle time compression. Some defense analysts have suggested that training in commercial logistics would change the culture of DoD inventory management and promote similar efficiencies. This thesis examines that idea in the context of ... |

Deborah J. Goodings; MARYLAND UNIV COLLEGE PARK DEPT OF CIVIL ENGINEERING
|
| Experimental data collected support the theorized scaling laws that predict that frost heave and thaw settlement in soil developing over one winter can be physically simulated over a matter of hours by freezing and thawing soil while rotating it on the arm of a geotechnical centrifuge. Different soils, ground water levels, and temperature regimes have been physically modelled at different scales. Comparison of an existing Army numerical model of heave ... |

|
| The conventional methods for image enhancement cannot be satisfactorily applied to the restoration of many types of images. This report explores standard image enhancement algorithms with emphasis on possible extensions to allow for real-time applications. The artifacts introduced by compression algorithms can often be compensated for by proper restoration techniques. A desktop conferencing system is prototyped in this report as a test-bed application to evaluate both real-time compression and real-time ... |

|
| A series of experiments testing the discrimination of random temporal patterns (single frequency tone sequences) was performed. The observer's task was to discriminate whether two sequences of tones contained the same or different patterns of temporal gaps. Half of the experimental trials contained gap sequences that were perfectly correlated across the two sequences (e.g. the temporal patterns were identical), and half the trials contained gap sequences that were partially correlated ... |

D. C. Kinney; AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH SCHOOL OF ENGINEERING
|
 | The first objective of this research was to design and fabricate a variation of the Jerison time estimation device. This modified Jerison device has the requirement of being STS compatiable; meaning it must be light weight, reliable, and totally self contained. The second objective of the research was to determine if providing feedback aids the subject in improving his TEA (Time Estimation Ability). When this research began the decision whether ... |

|
| This thesis establishes a base analysis for the determination of a method for wargaming both tactical and operational level courses of action. It orients on situations involving a compression of available time in which to decide on and execute the course of action. The study establishes the US Army estimate process as a base method for review and comparison. A review of the historical development of decisionmaking is included, as ... |

|
| A time compressed radar display system for presenting to the operator radar return video which has been accumulated over a relatively long period of time in a very short time span, preferably at TV frame rates. A scan converter receives the radar position data in polar coordinate format and converts it to rectangular coordinate format. Each of the rectangular cells, resulting from the scan conversion, is provided with an address. ... |

|
| Comparative tests were run between TIESPAD and the AN/SPA-66, a product-line shipboard PPI display. The Time Encoded Spatial Display (TIESPAD) is a radar video processing unit designed and built by Naval Ocean Systems Center. It is a 512 x 512 resolution scan converter with additional processing and memory to accomplish the time compression task using solid-state memory; the output is displayed on a TV monitor. The tests were run using ... |

|
| This study explores the effect of two variables, threat and time compression, on the decision making patterns of the senior decision units in selected international crises. The investigation is focused on an analysis of decision makers and their actions during two major crises of the twentieth-century; the Greek crisis of 1947, and the US decision to intervene in Korea, 1950. Investigation reveals that there are some common distinguishing characteristics of ... |

|
| This experiment studied five training methods for effective listening of time-compressed speech. Army subjects trained by two methods using incentives understood speech played 2.2 times faster than normal without degradation of performance. Subjects trained by three methods not using incentives had significantly degraded performance when compressed speech was presented at rates faster than 1.85 times the normal rate. (Author) |

|
| The design formulae and theoretical performance of a maximum-likelihood estimator for towed-array flow-speed estimation are discussed. Under appropriate conditions, it is shown that a maximum-likelihood estimate of convection velocity (which is related to tow speed) is achieved by performing a cross correlation between the outputs of two streamwise-separated flush-mounted surface probe hydrophones. The estimate, then, is derived by seeking the time delay which maximizes the cross correlation. Conditions are examined ... |

| Apparent Motion Quality and Target Detection on a Visually Time-Compressed Display. |

|
| Explanations of the superior target detection performance with visually time-compressed radar displays have involved the assumption that the coherent motion of the target against the random motion of background noise facilitates detection, much as the blossoming of a flower is made apparent by time-lapse photography. From the appearance of the display, this assumption seems reasonable; however, experimental findings are not fully explained in terms of apparent motion. The equivocal nature ... |
