 | For this research we created a human skin reflectance model in the VIS and NIR. We then modeled sensor output for an RGB sensor based on output from the skin reflectance model. The model was also used to create a skin detection algorithm and a skin pigmentation level (skin reflectance at 685nm) estimation algorithm. The average root mean square error across the VIS and NIR between the skin reflectance model ... |

| Context plays an important role when performing underwater classification, and in this report we examine context from two perspectives. First, the classification of items within a single task is placed within the context of distinct concurrent or previous classification tasks (multiple distinct data collections). This is referred to as multi-task learning (MTL), and is implemented here in a statistical manner, using a simplified form of the Dirichlet process. In addition, ... |

| Largely prescribed in a series of successive presidential executive orders issued over the past 50 years, security classification policy and procedure provide the rationale and arrangements for designating information officially secret for reasons of national security, and for its declassification as well. President Franklin D. Roosevelt issued the first executive order (E.O. 8381) in 1940. Current security classification policy may be found in Executive Order 12958, which was signed by ... |

| We propose a revision of the standard impulsive/gradual classification scheme for solar energetic particle (SEP) events. In the new scheme, SEP events are divided into two basic classes: Flare and Shock. The flare class corresponds to the old impulsive class, or more specifically, the 3He-rich subset of that class. The shock class, which replaces the gradual class, consists of two subclasses based on shock geometry and seed particle population, either ... |

| Background: Protein structures are critical for understanding the mechanisms of biological systems and, subsequently, for drug and vaccine design. Unfortunately, protein sequence data exceed structural data by a factor of more than 200 to 1. This gap can be partially filled by using computational protein structure prediction. While structure prediction Web servers are a notable option, they often restrict the number of sequence queries and/or provide a limited set of ... |

Subjects learned to classify targets as friend or foe on the bases of uncertain cues (i.e., characteristics that were probabilistically associated with classification of a target as friend or foe). Subjects were then asked to classify targets that contrasted predictions of several decision rules, including a simple heuristic called Take-the-Best-for- Classification (TTB-C) that ... |

| Self-Propelled Semi-Submersibles now transport an estimated 75% of cocaine originating from Colombia and headed for the United States. There are several types of search platforms (i.e., units to detect, classify, and interdict) being employed by the Joint Interagency Task Force South to combat the semi-submersibles. We use a defender-attacker optimization model to maximize the defender?s probability of successful detection and classification of the semisubmersible through the advantageous disposition of these ... |

| The trade-off between false alarm and detection probability is a fundamental challenge in the automated detection of contacts in passive sonar systems. A common approach is the application of high gain processing followed by successive classification criteria. Most classification schemes (e.g., matching of signature) are complex and tailored to specific target types. By contrast, the Doppler effect is readily observed in all contacts with discrete tonals and relative velocity to ... |
