 | Increasing computational power and memory capacity in desktop computers has resulted in access to numerical techniques previously unavailable to many users. Although computational capabilities have increased, many users are unable to take full advantage of this power due to limited programming expertise. Spreadsheets offer these users a means to capitalize upon computational potential without extensive training, though spreadsheet models can confer risks due to high error rates and lack of ... |

| Current methods of information retrieval (IR) are adequate for everyday search needs, but they are not appropriate for many military and industrial tasks. The underlying mechanism of typical search methods is based upon keyword matching, which has demonstrated very poor performance over highly technical requirements documents found within the field of acquisitions. Instead of matching keywords, IR methods that understand the meaning of the words in a query are needed ... |

Robert A Silva; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| Operational-level planners in Maritime Operations Centers aim to assign naval forces in support of combatant commanders efficiently and effectively, but they lack a software-based planning tool to develop optimal ship employment schedules. They must assign ships to particular missions spread throughout numerous regions over a particular time horizon to meet the combatant commander's force requirements. Currently, this is a manual process. We present Navy Mission Planner (NMP), a decision aid ... |

| New engineering disciplines are emerging in the late Twentieth and early Twenty-first Century. One such emerging discipline is software engineering. The engineering community at large has long harbored a sense of skepticism about the validity of the term software engineering. During most of the fifty-plus years of software practice, that skepticism was probably justified. Professional education of software developers often fell short of the standard expected for conventional engineers; software ... |

| Delta-N-p63 plays a critical role in making decision to preserve or forfeit mammary stem cells/progenitor cells self-renewal capacity. In embryonic stem cells, some transcription factors including oct3/4, nanog, c-myc and Klf-4 are critical to maintain self-renewal and multi-potential stasis. Our study revealed that these key transcription factors also exist in adult mammary stem cells/progenitor cells as well as breast cell lines such as IMEC, MCF-10A, SUM102 and MCF- 7 cells. ... |

| Structural synthesis is a method of calculating the transient dynamic response of an assemblage of substructures without explicitly assembling and solving a combined system model. While significant computational advantages are provided by this method, the modal parameters of the combined system are not explicitly calculated. Hence, a method is needed to allow the a priori determination of the substructure damping levels such that the synthesized system damping is within user-prescribed ... |

| At present, designers of real-time systems face a dilemma between expressiveness and automatic verification: if they can specify some aspects of their system in some automaton-based formalism, then automatic verification is possible; but more complex system components may be hard or impossible to express in such decidable formalisms. These more complex components may still be simulated; but there is then little support for their formal analysis. The main goal of ... |

| Abnormalities in programmed cell death (apoptosis) machinery play a crucial role in initiation progression and metastasis of prostate cancer. Therefore molecules that initiate pro-apoptotic pathways are excellent therapeutic agents in prostate cancer. However some prostate cancer cells develop resistance to pro-apoptotic agents. In this proposal we are examining the regulatory mechanisms of c-FLIP(L) which is an important modular of apoptosis in prostate cancer. |
