 | This report details the research that went into the bacterial component of the enzyme-based immunoassays developed for the Mobile Agent Identification Unit (MAGIDU), and were deployed during Operation Friction in the Persian Gulf in 1991. A rapid whole cell enzyme-linked immunosorbent assay (ELISA) was quickly developed for the identification of selected bacterial agents. The early research concentrated on the identification of Bacillus anthracis whole cells, and the resulting assays were ... |

|
 | A liquid chromatographic method has been developed for the analysis of N-Nitroso-N- ethylurea (ENU) in salt water by high performance liquid chromatography (HPLC). Samples are injected directly onto a HPLC without sample preparation. Separation of ENU from possible interferences found in salt water was achieved using a C-18 DB column and a mobile phase containing methanol and water. A programmable ultra- violet detector was used to monitor the effluent for ... |

|
| We consider the problem of computing a time-optimal motion for two robots carrying a ladder from all initial position to a final position in a plane without obstacles. At any moment during the motion, the distance between the robots remains unchanged and the speed of each robot must be either a given constant v, or 0. A trivial lower bound on time for the robots to complete the motion is ... |

| Security and inspection systems are becoming increasingly automated. Many such systems include mobile platforms capable of autonomous sensing and analysis of the environment from a multitude of perspectives. This increased automation shifts the responsibilities of humans from active patrolling and inspection to passive monitoring of remote sensor information. The operator brings perceptual and cognitive characteristics to this task which need to be addressed in both system architecture and interface design ... |

| The Global Grid communications environment is designed to provide a high-data-rate network that supports the full complement of DoD communications needs. Satellite links are an integral part of the Global Grid concept which extends the connectivity to individual mobile units and jointly operating forces at isolated locations. However, satellite channels are vulnerable to jamming, in particular when a high data rate is required. To overcome the jamming problem, the traditional ... |

| Bacterial strains (many isolated from soil and subsurface environments) and their extracellular polymers were tested for their ability to enhance the transport of phenanthrene, a model PAH, in a low-carbon aquifer sand. All of the bacterial isolates tested passively sorbed phenanthrene, and most of the isolates reduced the distribution coefficient (K(d) ) for phenanthrene. Some isolates were also mobile in column experiments. The most mobile isolate significantly enhanced the transport ... |

| The Mobile Kitchen Trailer (MKT) uses 6 M-2 gasoline burners to heat a griddle, range cabinets and cooking racks. These cooking appliances do not currently have any type of chimney or vent, so all combustion products from the burners go into the kitchen. Accordingly, a ventilation system (i.e. equipment vents) was designed, fabricated and tested for the MKT to reduce the probability of clinical symptons that have ranged from mild ... |

| In the 1920s and 1930s, the United States Cavalry confronted fundamental questions about its identity framed within the context of intense branch partisanship and severe manpower and budgetary constraints. While it took prudent steps to maintain as powerful and modern a body of horse cavalry as possible, an intense struggle for the soul of the institution raged. Conservative officers insisted cavalry was the arm that fought on horseback. Pro-mechanization reformers ... |

| Cyclodextrin inclusion complexes were formed from p-nitroanilines and aniline analogs as well as from selected bimanes. Only in very few instances did complexation with cyclodextrins increase the second harmonic generation when compared to the parent compound (aniline/analog or bimane). Solid state UV reflectance spectroscopy was found to be a viable method for differentiating between solid cyclodextrin-guest inclusion complexes and cyclodextrin-guest physical admixtures. Isobestic points could be determined by solution UV ... |

| To maximize effectiveness, theater missile defense (TMD) should include counterforce options, active defenses and passive defenses. During the Gulf War, however, the integration of these three elements occurred on an ad hoc basis. To increase the political, strategic and tactical effectiveness of existing defensive systems in wartime, Army planners should integrate the three elements of TMD into an overall strategy. This report describes how the philosophy that influenced antisubmarine warfare ... |

Each robots is a mobile processor that, at each discrete time instant, observes the relative positions of those robots that are within distance V of itself, computes its new position using the given algorithm, and then moves to that position. The main difference between this work and many of the previous ones is that, here, the ... |

| Disconnected operation is an important technique for providing mobile access to shared data in distributed file systems. However, data inconsistency resulting from partitioned sharing remains a serious concern. This paper presents a new mechanism called isolation-only transaction(IOT) that uses serializability constraints to automatically detect read/write conflicts. The IOT consistency model provides a set of options for automatic and manual conflict resolution. In addition, application specific knowledge can be incorporated to ... |

|
| The adsorption and dissociation of trimethylgallium (TMG, Ga(CH3)3) on the Si(001) surface has been studied using Scanning Tunneling Microscopy (STM). The products of TMG dissociation are identified by their bonding location with respect to the underlying Si(001) lattice, by bias dependent imaging and from detailed counting statistics. TMG is found to adsorb dissociatively at room temperature, yielding a methyl group and a dimethylgallium fragment bound to the surface. The Ga(CH3)2 ... |

Over the years doctrine has traditionally defined the range of possible defenses as existing on a continuum of defensive operations. This continuum has been variously defined at its ends by mobile' and 'static' poles. These poles have usually been objectified respectively as the mobile and area defenses. This study maintains that the mobile defense ... |

| The concepts of flow vectoring have long been established through the use of mechanical moving surfaces such as ailerons, elevators, flaps, etc. to redirect the local flow on an aircraft in order to obtain high-lift control and thrust-vectoring. Only recently has aerodynamic flow vectoring been investigated whereby the flow may be redirected without any movable surfaces. The present study has addressed the open loop control of a wake by means ... |
