Abstract : This report provides interim guidelines for the layaway and periodic inspection, maintenance, and repair of historic buildings on U.S. Army installations. It builds on previous facility layaway research by the U.S. Army Construction Engineering Research Laboratory (CERL) documented in CERL Technical Report M-91/23 (July 1991). This report describes the specific requirements for laying away historic buildings, providing guidelines for inspection and periodic maintenance and repair (M&R) for key building systems, components, and subcomponents. Topics discussed include definitions of historic buildings, Federal guidelines for laying away historic buildings, inspection purposes and guidelines, and categories of required M&R for laid away historic facilities. Appendixes to this report include eight extensive checklists to help guide the inspection and M&R of major building systems and components.
TemporalNode2vec: Task-agnostic and Task-specific Temporal Node Embedding

The goal of graph embedding is to learn a representation of graphs vertices in a latent low-dimensional space in order to encode the structural information that lies in graphs. While real-world networks evolve over time, the majority of research focuses on static networks, ignoring local and global evolution patterns. A simplistic approach consists of learning nodes embeddings independently for each time step. This can cause unstable and inefficient representations over time. In this paper, we present TemporalNode2vec, a novel dynamic graph embedding approach that learns continuous time-aware node representations. Overall, we demonstrate that our method improves node classification tasks comparing to previous static and dynamic approaches as it achieves up to 14% gain regarding the F1 score metric. We also prove that our model is more data-efficient than several baseline methods, as it affords to achieve good performances with a limited number of node representation features. Moreover, we develop and evaluate a task-specific variant of our method called TsTemporalNode2vec, aiming to improve the performances and the data-efficiency of node classification tasks.
A Comprehensive Data Analysis of Differentially Regulated Genes in Melanoma

Background: Melanoma is the most deadly tumor in skin tumors and is prone to distant metastases. The incidence of melanoma has increased rapidly in the past few decades, and current trends indicate that this growth is continuing. This study was aimed to explore the molecular mechanisms of melanoma pathogenesis and discover underlying pathways and genes associated with melanoma.Methods: We used high-throughput expression data to study differential expression profiles of related genes in melanoma. The differentially expressed genes (DEGs) of melanoma in GSE15605, GSE46517, GSE7553 and the Cancer Genome Atlas (TCGA) datasets were analyzed. Differentially expressed genes (DEGs) were identified by paired t-test. Then the DEGs were performed cluster and principal component analyses and protein–protein interaction (PPI) network construction. After that, we analyzed the differential genes through bioinformatics and got hub genes. Finally, the expression of hub genes was confirmed in the TCGA databases and collected patient tissue samples.Results: Total 144 up-regulated DEGs and 16 down-regulated DEGs were identified. A total of 17 gene ontology analysis (GO) terms and 11 pathways were closely related to melanoma. Pathway of pathways in cancer was enriched in 8 DEGs, such as junction plakoglobin (JUP) and epidermal growth factor receptor (EGFR). In the PPI networks, 9 hub genes were obtained, such as loricrin (LOR), filaggrin (FLG), keratin 5 (KRT5), corneodesmosin (CDSN), desmoglein 1 (DSG1), desmoglein 3 (DSG3), keratin 1 (KRT1), involucrin (IVL) and EGFR. The pathway of pathways in cancer and its enriched DEGs may play important roles in the process of melanoma. The hub genes of DEGs may become promising melanoma candidate genes. Five key genes FLG, DSG1, DSG3, IVL and EGFR were identified in the TCGA database and melanoma tissues.Conclusions: The results suggested that FLG, DSG1, DSG3, IVL and EGFR might play important roles and potentially be valuable in the prognosis and treatment of melanoma.
Laser Remote Sensing: FY07 Summary Report

Standoff detection and characterization of chemical plumes using Frequency Modulated Differential Absorption Lidar (FM-DIAL) is a promising technique for the detection of nuclear proliferation activities. For the last several years Pacific Northwest National Laboratory (PNNL) has been developing an FM-DIAL based remote sensing system as part of PNNL's Infrared Sensors project within NA-22's Enabling Technologies portfolio. In FY06 the remote sensing effort became a stand-alone project within the Plutonium Production portfolio with the primary goal of transitioning technology from the laboratory to the user community. Current systems remotely detect trace chemicals in the atmosphere over path lengths of hundreds of meters for monostatic operation (without a retro-reflector target) and up to ten kilometers for bistatic operation (with a retro-reflector target). The FM-DIAL sensor is sensitive and highly selective for chemicals with narrow-band absorption features on the order of 1-2 cm-1; as a result, the FM-DIAL sensors are best suited to simple di-atomic or tri-atomic molecules and other molecules with unusually narrow absorption features. A broadband sensor is currently being developed. It is designed to detect chemicals with spectral features on the order of several 10s of wavenumbers wide. This will expand the applicability of this technology to the detection of more complicated molecules. Our efforts in FY07 focused on the detection of chemicals associated with the PUREX process. The highest value performance measure for FY07, namely the demonstration of the Broadband Laser Spectrometer (BLS) during chemical release experiments, was successfully achieved in June, July and August of this year. Significant advancements have been made with each of the other tasks as well. A short-wave infrared version of the miniature FM-DIAL (FM-Mini) instrument was successfully demonstrated during field tests in June. During FY07 another version of the FM-Mini was built using long-wave infrared components. This instrument was deployed for field tests in July and August. The modeling task continued to study the impact of speckle on the FM-DIAL system as well as make further advancements in the sophistication of the numerical simulations.
Bachelors

First-year computer science students frequently encounter difficulties in programming. A major contributing factor to these challenges is the presence of unclear and vague error messages. These unhelpful error messages are an especially big problem for novice programmers, as they lack the necessary experience to immediately see what is going wrong and are therefore dependent on error messages to solve errors. In this thesis, we present several ways in which the presentation of error messages can be improved to make them more helpful for novice programmers. We then go on to implement and evaluate some of these methods. Finally, we provide evidence that indicates that they are an improvement upon standard error messages.
Then What? Quantifying SBAE Teacher Career-Decisions Post-Migration

Complex career decisions, such as teacher mobility, are often reduced to stigmatizing labels that do little to account for the state of teaching as a profession or credit those engaging in migratory decisions as making healthy career choices. Through our study, we focused on understanding workforce mobility, teaching as an unstaged profession, and the current quantifications existing around SBAE teacher migration. We drew on over 100 years of data from California as we quantitatively explored and synthesized the career decisions of migrating SBAE teachers. This snapshot offers a means of understanding the Teacher Career Cycle (Fessler & Christensen, 1992) in light of the implications for the teaching career as a series of choices rather than a stretch of time at an individual school. Implications of this conceptualization of migration stretch beyond SBAE to administration and those tasked with supporting the career trajectory of SBAE teachers across the United States.
User Interface for Unmanned Combat Vehicle Based on Mission Planning and Global Path Planning

In this paper, a new user interface for unmanned combat vehicle(UCV) is developed based on the mission planning and global path planning. In order to complete a tactical mission given to an UCV, it is essential to design an effective interface scheme between human and UCV considering changing combat environment and characteristics of the mission. The user interface is mainly composed of two parts, mission planning and global path planning, since they are important factors to accomplish combat missions. First of all, mission types of UCV are identified. Based on mission types, the concept of mission planning for UCVs is presented. Then a new method for global path planning is devised. It is capable of dealing with multiple grid maps to consider various combat factors so that paths suitable for the mission be generated. By combining these two, a user interface method is suggested. It is partially implemented in the Dog-horse Robot of ADD and its effectiveness is verified.
Potential of Different Fungi Species in Biodegradation Field of Phenolic Compounds

Phenolic compounds are dominant pollutants in terrestrial and freshwater environmental that have toxic effects on living organisms at low concentrations, because it has the ability to persist in the ecosystem. So bio-removal is a good technique that employs the metabolic potential of microorganisms to clean up the environmental pollutants and turned into less dangerous or harmless substances. This work aims to the isolation of different species of fungi from wastewater of factories and Red Sea coast to test the ability of these fungi to degrade phenolic compounds. Ten species of fungi and sterile mycelium are used to degrade phenol and its derivatives at different concentrations (0.4%, 0.6% and 0.8%). All fungi species have the ability of degradation of phenol and their derivatives, but P. chrysogenum, Saccharomyces sp. and sterile mycelium exhibited low ability to break down of hydroxyl-benzene, 2-naphthol and 1,3 dihydroxy benzene, respectively.
Design and Realization of a Digital Baseband Subsystem of Wakeup Receiver for Wireless Sensor Networks

In the development of wireless sensor networks, the lifetime of a sensor node is always a key design consideration. Since the battery in a sensor node can usually not be recharged or changed, power management is an effective way to extend the network lifetime. The wireless transceiver, also regarded as the ‘main radio’, is a relatively power hungry component in a sensor node. Therefore, an auxiliary always-on hardware ‘wakeup radio’ was proposed in order to reduce the overall power consumption. The wakeup radio listens to the wireless channel whereas the main radio is only active for a rather short time when the wakeup radio receives the packet with a certain pattern. Consequently, the power efficiency becomes a primary concern in the design of wakeup radio. This thesis focuses on the low power design and implementation of a digital baseband subsystem in the wakeup radio. Firstly, the architecture and details of the subsystem are described. Then the design is verified by both a Spartan-3 FPGA board and TSMC90 chips. The design is functional as designed. In the end, the chip measurement setup and results are discussed. The power consumption varies from 2.1 ? w to 8.4 ? w, within our design target of 10 ? w. To our knowledge, it is the first work on the digital implementation and chip measurement of the wakeup radio.
Design and Analysis of a Yagi-Like Antenna Element Buried in LTCC Material for AEHF Communication Systems

Abstract : This document presents the investigation of an end-fire antenna implemented in a laminated material named LTCC (Low Temperature Co-fired Ceramic). This study is related to the development of a phased array for the AEHF Military Satellite Communication Systems. This work includes the design, the analysis, fabrication and the measurement of antenna prototypes at 44.5 GHz. The radiating element consists of a Yagi-like antenna fed by a microstrip transmission line and buried into the dielectric material. Relatively good agreement between simulated results and measurement is obtained. The results shows that this radiating element could be used for AEHF Communication systems. The next step is to study its electromagnetic behaviour in an array configuration. As the LTCC material has not previously been characterized up to 45 GHz, a study to extract the electrical properties of the LTCC material has been carried out, and is also reported in this document.
Coatings for Selective Microwave Absorption

Abstract : A fundamental consideration in the design of military communication systems today is combat survivability in a highly hostile environment. In the absence of such survivability potential, the ability of most critical communication systems to fulfil its mission is jeopardized. Communication survivability depends upon many factors: (1) Protection from EMI/RFI/EMP; (2) Protection from temperature/weather; (3) Protection from high power microwave (HPM) during EW; and (4) Protection from ordinary ground based or air-borne radar. This research attempts to find a solution for one such threat namely protection from HPM. The main objectives of this research work is to develope a low cost microwave absorptive materials(MAM) to protect electronic components, devices, and equipment from HPM. The objectives are to identify, characterize, and evaluate sample absorptive materials. Another requirement of this research work was to develope a product that can be formulated in such a way so that it can be applied very easily on a variety of components such as printed circuit boards, coaxial wave guide low-pass/high pass or pass band filters, radomes and antennas

It is intended to provide an overview of PKI functions and their applications. Additional documentation will be required to fully analyze the costs and benefits of PKI systems for agency use, and to develop plans for their implementation. This document provides a starting point and references to more comprehensive publications.
X-Ray Computed Tomography of Castings

Abstract : Computed Tomography (CT) offers an inspection capability with potential to overcome some of the shortcomings in inspection which affect the utilization of castings in the aircraft/aerospace industry. To this end, castings defect samples were excised from larger cast parts and utilized to evaluate CT sensitivity to a variety of defect types and sizes relative to conventional film radiography. The defects were also inserted into larger cast structures to evaluate loss of sensitivity as a function of geometry. Dimensional phantoms were fabricated to test dimensional measurement accuracy of CT systems. Five different CT systems were used for the CT scanning. Data from resolution and contrast sensitivity phantoms, developed for the program, were used to establish quantitative measures of imaging capability.
Response Surface Methodology Design Variants Useful in Human Performance Research

Abstract : Selected Response Surface Methodology (RSM) designs that are viable alternatives in human performance research are discussed. Two major RSM designs that are variations of the basic, blocked, central-composite design were selected for consideration: central-composite designs with multiple observations at only the center point, and central-composite designs with multiple observations at each experimental point. Designs of the latter type are further categorized as: designs which collapse data across all observations at the same experimental point; between-subjects designs in which no subject is observed more than once, and observations at each experimental point may be multiple and unequal or multiple and equal; and within-subject designs in which each subject is observed only once at each experimental point. The ramifications of these designs are discussed in terms of various criteria such as rotatability, orthogonal blocking, and estimates of error.
Expert and Novice Fire Ground Command Decisions

Abstract : There is a need to develop descriptive models of decision making under conditions of risk, ambiguity, and time pressure. As part of an ongoing effort to develop such a model, the present study performed a Critical Decision analysis of decisions made by 12 Expert and 12 Novice fire ground commanders. A coding system was developed for this study and 104 decision points were classified and described. The findings do not support the prevalent view of decision making as evaluation between options. 54% of the decision points relied most extensively on predecisional processes involving problem identification and clarification, 15% involved questions of specific timing or control, and 13% involved serial evaluation of a single option. Thus, only 18% of the decisions involved concurrent option evaluation. Differences between Expert and Novice commanders are also discussed.
Performance Analysis of Nonlinear Systems Combining Integral Quadratic Constraints and Sum-of-Squares Techniques

This thesis investigates performance analysis for nonlinear systems, which consist of both known and unknown dynamics and may only be defined locally. We apply combinations of integral quadratic constraints (IQCs), developed by Megretski and Rantzer, and sum-of-squares (SOS) techniques for the analysis.In this context, analysis of stability and input-output properties is performed in three ways.If the known portion of the dynamics is linear, the stability test from Megretski and Rantzer, which generalize early frequency-domain based theorems of robust control (Zames, Safonov, Doyle, and others), are well suited. If the known portion of the dynamics is nonlinear, frequency domain methods are not directly applicable. SOS methods using polynomial storage functions to satisfy dissipation inequalities are used to certify the stability and performance characteristics. However, if the known dynamics are high dimensional, then this approach to the analysis is (currently) intractable. An alternate approach is proposed here to address this dimensionality issue. The known portion is decomposed into a linear interconnection of smaller, nonlinear systems. We derive IQCs satisfied by the nonlinear subsystems. This is computationally feasible. With this library of IQCs coarsely describing the subsystems' behaviors, we apply the techniques from Megretski and Rantzer to the interconnection description involving the known linear part and all of the individual subsystems. Traditionally, IQCs have been used to cover unknown portions of the dynamics. Our approach is novel in that we cover known nonlinear dynamics with IQCs, by employing SOS methods including novel techniques for estimating the input-output gain of a system. This perspective is a step towards reducing the dimensionality of the analysis of large, interconnected nonlinear systems. The IQC stability analysis by Megretski and Rantzer is only applicable for systems that are well-posed in the large. This thesis makes contributions towards extending this analysis for with more limited notions of well-posedness. We define the notion of a local or conditional IQC, and develop a new test to verify stability and performance criteria.We also study a specific class of interconnected, passive subsystems. If the subsystems also exhibit gain roll-off at high frequencies, one would expect improved analysis results. In fact, we characterized the gain roll-off property as an integral quadratic constraint, and achieved an improved bound on the performance with respect to the allowable time delay in order for the interconnected system to remain stable. In the case where the interconnection is cyclic, we derive an analytical condition for stability.
Research of Influence of Engagement Pairing of the Corrected Worm Gear with Involute Worm on the Life and Contact Pressure

The impact of meshing type in involute worm gears as well as the effect of tooth correction and their wear are analyzed by the author’s own method for calculating worm gear life. Qualitative and quantitative regularities are established regarding the effect of tooth wear on the variation in the maximum contact pressures and minimum life of the gear. The minimum life of the gear with triple-pair meshing is higher by 1.46 times when compared to that of the gear with double-pair meshing. Following the tooth correction, the minimum gear life is increased by 1.22 times. The maximum contact pressure under the triple-pair meshing conditions is lower by 1.22 times when compared to the double-pair meshing case, and the correction of the gear teeth leads to a reduction in the maximum contact pressure by 1.28 times. Predictive estimation of the specified contact parameters and tribotechnical characteristics of the worm gear was performed using experimentally determined indicators of material wear resistance.
Advanced dexterous manipulation for IED defeat : report on the feasibility of using the ShadowHand for remote operations.

Improvised Explosive Device (IED) defeat (IEDD) operations can involve intricate operations that exceed the current capabilities of the grippers on board current bombsquad robots. The Shadow Dexterous Hand from the Shadow Robot Company or 'ShadowHand' for short (www.shadowrobot.com) is the first commercially available robot hand that realistically replicates the motion, degrees-of-freedom and dimensions of a human hand (Figure 1). In this study we evaluate the potential for the ShadowHand to perform potential IED defeat tasks on a mobile platform.
Intramolecular Proton Transfer in the Isomerization of Hydroxyacetone: A Detailed Characterization Based on Reaction Force Analysis and the Bond Fragility Spectrum

The mechanism of isomerization of hydroxyacetone to 2-hydroxypropanal is studied within the framework of reaction force analysis at the M06-2X/6-311++G(d,p) level of theory. Three unique pathways are considered: (i) a step-wise mechanism that proceeds through formation of the Z-isomer of their shared enediol intermediate, (ii) a step-wise mechanism that forms the E-isomer of the enediol, and (iii) a concerted pathway that bypasses the enediol intermediate. Energy calculations show that the concerted pathway has the lowest activation energy barrier at 45.7 kcal mol-1. The reaction force, chemical potential, and reaction electronic flux are calculated for each reaction to characterize electronic changes throughout the mechanism. The reaction force constant is calculated in order to investigate the synchronous/asynchronous nature of the concerted intramolecular proton transfers involved. Additional characterization of synchronicity is provided by calculating the bond fragility spectrum for each mechanism.
