 | Tools were developed for the representation and analysis of uncertainty in INTEL data and targeted uncertainty reduction. The purpose is to help INTEL analysts answer these questions: 1) What hypotheses can be validated/refuted based on available uncertain data and at what level of certainty? 2) What missing data is critical for verifying or refuting given hypotheses and increasing the certainty of current conclusions? 3) What are the tradeoffs between the ... |

|
| Previous work to develop a microfibrillar array to improve mask sealing performance demonstrated increased wet and dry adhesion on rigid and soft smooth substrates using spatulate fibers. The current effort modeled and characterized dry fibrillar adhesion to substrates that more closely approximate human skin. The models for adhesion to soft, textured substrates revealed that the resulting adhesion was simply a fraction of the adhesion to a smooth, rigid substrate. The ... |

| Authors:
Katia Sycara; Cuihong Li; Joseph Giampapa; CARNEGIE-MELLON UNIV PITTSBURGH PA
|
| We present a model for bilateral negotiations that considers the uncertain and dynamic outside options. Outside options affect the negotiation strategies via their impact on the reservation price. The model is composed of three modules, single-threaded negotiations, synchronized multi-threaded negotiations, and dynamic multi-threaded negotiations. These three models embody increased sophistication and complexity. The single-threaded negotiation model provides negotiation strategies without specifically considering outside options. The model of synchronized multi-threaded negotiations ... |

| An influence network is a directed graph extensively used for Effects-Based Operation. It contains nodes that represent events and links that encode causal relationships among events. It propagates the likelihood of each event through promotion or inhibition by its parents. As a subject matter expert often builds this network by hand, we helped simplify the influence network generation in Organization Risk Analyzer. The resulting influence network is generated from a ... |

| Route redistribution (RR) has become an integral part of IP network design as the result of a growing need for disseminating certain routes across routing protocol boundaries. While RR is widely used and resembles BGP in several nontrivial aspects, surprisingly, the safety of RR has not been systematically studied by the networking community. This paper presents the first analytical model for understanding the effect of RR on network wide routing ... |

| The cost of direct computation of the detection error probabilities in a sensor network -- e.g., the probability of false alarm, the probability of a miss, or the average probability of error -- is combinatorial with the number of sensors. This limits the design of the optimal detector to networks with a very small number of sensors. Our work developed a simple very accurate large-deviation method to compute these probabilities ... |

| Lab-on-a-chip (LoC) systems can be functionally decomposed into their basic operating devices. Common devices are mixers, reactors, injectors, and separators. In this paper, the injector device is modeled using artificial neural networks (NNs) trained with finite element simulations of the underlying mass transport partial differential equations (PDEs). This technique is used to map the injector behavior into a set of analytical performance functions parameterized by the system's physical variables. The ... |

| Most attack taxonomies are organized from the perspective of attackers' goals. One example of an attacker goal is privilege escalation from user to root. Taxonomies based on attacker goals are attack-centric, largely serving the goals of an attacker, and to a lesser extent, the defender. Defenders need a way of determining whether or not their detectors will detect a given attack. A defense-centric taxonomy may be better suited to this ... |

| One increasingly important technique for improving software-based system integrity is providing systems with the ability to adapt themselves at run time to handle such things as resource variability, changing user needs, and system faults. Traditionally system self repair has been handled within the application, and at the code level. An alternative approach, and the approach taken under this effort, is to use architectural models, maintained at run time, as the ... |

The compositions (Fe50Co50)89Zr7B4 and (Fe65Co35)89Zr7B4 were investigated changing the Fe:Co ratio from 50:50 to 65:35. (Fe50Co50)85Zr2Nb4B8.5 was chosen to investigate Nb substitution for Zr in an FeCo-based alloy. This substitution is shown to increase the magnetostrictive constant, lambdaS, of the nanocrystalline alloy from 36x10(exp -6) ... |
