Polyamines and Legumes: Joint Stories of Stress, Nitrogen Fixation and Environment

Polyamines (PAs) are natural aliphatic amines involved in many physiological processes in almost all living organisms, including responses to abiotic stresses and microbial interactions. On other hand, the family Leguminosae constitutes an economically and ecologically key botanical group for humans, being also regarded as the most important protein source for livestock. This review presents the profuse evidence that relates changes in PAs levels during responses to biotic and abiotic stresses in model and cultivable species within Leguminosae and examines the unreviewed information regarding their potential roles in the functioning of symbiotic interactions with nitrogen-fixing bacteria and arbuscular mycorrhizae in this family. As linking plant physiological behavior with “big data” available in “omics” is an essential step to improve our understanding of legumes responses to global change, we also examined integrative MultiOmics approaches available to decrypt the interface legumes-PAs-abiotic and biotic stress interactions. These approaches are expected to accelerate the identification of stress tolerant phenotypes and the design of new biotechnological strategies to increase their yield and adaptation to marginal environments, making better use of available plant genetic resources.
A Comparison of Alternative Intervention Strategies for Unintended Roadway Departure (URD) Control

SUMMARY This paper investigates the use of several different inputs for the control of a vehicle, in the context of URD. In this investigation, the goal of the URD controller is to provide an intervention in the event of the vehicle leaving the road. The types of inputs that will be considered are (i) Four Wheel Steering, (ii) Front Wheel Steering, (iii) Four Wheel Brake Steering, (iv) Front Wheel Brake Steering, and (v) Rear Wheel Brake Steering. The controller design is an LQ controller based on the simplified dynamics of a 2 degree of freedom bicycle model. However, the analysis of the different strategies are performed on a 7 degree-of-freedom nonlinear vehicle model. The key contribution of this paper is the quantitative evaluation of the relative efficiencies of each of these input strategies being examined. Unlike most control schemes, the performance measure to be used will not be the output tracking error of the system. Instead, the metric of performance is the ratio of peak tire force used versu.
Properties of Microstrip Line on Si-SiO/sub 2/ System

A parallel-plate waveguide model for the microstrip line formed on the Si-SiO/sub 2/ system is analyzed theoretically and the results are compared with the experiment. The experiment has been performed over wide ranges of frequency, substrate resistivity, and strip width. Existence of three types of fundamental modes is concluded and the condition for the appearance of each mode is clarified. In particular, the slow-wave mode is found to propagate within the resistivity-frequency range suited to the monolithic circuit technology, and its propagation mechanism is discussed. Approximate analysis of the fringing effect is also made for the slow-wave mode.
Volume III: The Iron Age

NASA Conference on Space Telerobotics These proceedings contain papers presented at the NASA Conference on Space Telerobotics held in Pasadena, January 31February 2, 1989. The Conference was sponsored by the NASA Office of Aeronautics and Space Technology, together with ARC, LRC, GSFC, JSC, MSFC, KSC and JPL. The theme of the Conference was man-machine collaboration in space. The Conference provided a forum for researchers and engineers to exchange ideas on the research and development required for application of telerobotics technology to the space systems planned for the 1990s and beyond. The Conference: (i) provided a view of current NASA telerobotic research and development; (ii) stimulated technical exchange on man-machine systems, manipulator control, machine sensing, machine intelligence, concurrent computation, and system architectures; and (iii) identified important unsolved problems of current interest which can be dealt with by future research. There were about 500 international participants including about i00 from abroad. An international program committee was established for the conference. A.K. Bejczy and H.

Application Research on TD-LTE Technology in Communication System of Power Distribution and Utilization Network

Firstly the current situation and demand of power wireless communication was analyzed, and the technical characteristics of a variety of wireless communication applicated in the area of distribution were summarized, then, Considering strict requirement for QoS, high data rate, mass uplink data, and a large number of users, a solution based on TD-LTE Technology is purposed for 230MHz broadband wireless transmission. Therefore, MIMO, OFDMA and Carrier Aggregation Technology are all improved to realize the broadband wireless transmission of power communication under the condition of discrete, narrowband carrier.
Visible quasi-phase-matched harmonic generation by electric-field-poled lithium niobate

Laser-based displays and illumination systems are applications which can capitalize on the brightness and efficiency of semiconductor lasers, provided that there is a means for converting their output into the visible spectrum. Semiconductor laser manufacturers can adjust their processes to achieve desired wavelengths in several near-infrared bands; an equally agile conversion technology is needed to permit display and illumination system manufacturers to choose visible wavelengths appropriate to their products. Quasi- phasematched second harmonic generation has the potential to convert high-power semiconductor laser output to the visible with 50% optical-to-optical conversion efficiency in a single-pass bulk configuration, using electric-field-poled lithium niobate. Lithographically- defined electrode structures on the positive or negative polar faces of this crystal are used to control the formation of domains under the influence of electric fields applied using those electrode structures. The quality of the resulting domain patterns not only controls the efficiency of quasi-phasematched second harmonic generation, but also controls the degree of resistance to photorefractive damage. We present a model which is used to identify the optimum electrode duty cycle and applied poling field for domain patterning and compare the predicted domain duty cycle with experimental results. We discuss factors which contribute to inhomogeneous domain pattern quality for samples poled under otherwise ideal conditions and our progress in limiting their influence. Finally, we present optical characterization of a 2.4 mm long 500 micrometers thick sample which produced an average second harmonic power of 1.3 W of 532 nm green from a 9 W average power Q-switched 1064 nm Nd:YAG laser in a loose- focus single-pass configuration.
Design considerations for thin-film SOI/CMOS device structures

Allowable design regions for thin-film SOI/CMOs device structures, taking account for the relation between SOI film thickness and the concentration of SOI substrate impurities, are investigated. Not only are the advantages of thin-film SOI MOSFETs verified, but constraints on threshold voltage and kink-free controls are also shown. Conventional n/sup +/ poly-Si gate NMOSFETs tend to have difficulty in maintaining high transconductance for deep submicrometer gate length because of the constraints of normally-off threshold voltage and kink-free characteristics. By choosing a gate with the same work function as the intrinsic silicon semiconductor, the allowable design regions for deep submicrometer gate SOI MOSFETs are expected to have a low-impurity SOI substrate and an optimized threshold voltage for high-performance SOI/CMOS LSIs. The device scaling for various gate electrodes are also discussed for 1- to 0.2 mu m gate SOI/CMOS devices. >
English Speakers in Hong Kong

This paper argues it is no longer possible to refer to Hong Kong English speakers en masse as EFL speakers, nor can we say they speak a fully formed new variety of English called Hong Kong English (HKE). Taking into account the language(s) used for school, for work, for entertainment, and for socializing, we can see that Hong Kong’s speech community is extremely heterogeneous, both regarding levels of English and degrees of English usage. A small but growing number of Hongkongers now report that they speak English as a native language. Hongkongers with white collar jobs have been found to write more English than Chinese while at work, making it reasonable to argue that they write English as a second language (ESL). Many Hongkongers seek out English-speaking social networks and choose to watch and listen to English-medium forms of entertainment, which means their English-speaking experience is very ESL-like. However, in addition to these variations, there are great differences in English speaking and writing abilities that correlate largely with socioeconomic status. Adding to this lack of homogeneity among English speakers is the fact that extremely few Hongkongers speak English among themselves outside of specific work or school contexts. This means that HKE is not yet a new variety of English, and will have a difficult time becoming one unless the linguistic habits of Hongkongers change. English language education should take all these individual differences into account, including potentially wide differences in the speaking, listening, reading and writing abilities among individuals themselves.

Mobile detection assessment and response systems (MDARS): a force protection physical security operational success

MDARS is a Semi-autonomous unmanned ground vehicle with intrusion detection & assessment, product & barrier assessment payloads. Its functions include surveillance, security, early warning, incident first response and product and barrier status primarily focused on a depot/munitions security mission at structured/semi-structured facilities. MDARS is in Systems Development and Demonstration (SDD) under the Product Manager for Force Protection Systems (PM-FPS). MDARS capabilities include semi-autonomous navigation, obstacle avoidance, motion detection, day and night imagers, radio frequency tag inventory/barrier assessment and audio challenge and response. Four SDD MDARS Patrol Vehicles have been undergoing operational evaluation at Hawthorne Army Depot, NV (HWAD) since October 2004. Hawthorne personnel were trained to administer, operate and maintain the system in accordance with the US Army Military Police School (USAMPS) Concept of Employment and the PM-FPS MDARS Integrated Logistic Support Plan. The system was subjected to intensive periods of evaluation under the guidance and control of the Army Test and Evaluation Center (ATEC) and PM-FPS. Significantly, in terms of User acceptance, the system has been under the "operational control" of the installation performing security and force protection missions in support of daily operations. This evaluation is intended to assess MDARS operational effectiveness in an operational environment. Initial observations show that MDARS provides enhanced force protection, can potentially reduce manpower requirements by conducting routine tasks within its design capabilities and reduces Soldier exposure in the initial response to emerging incidents and situations. Success of the MDARS program has been instrumental in the design and development of two additional robotic force protection programs. The first was the USAF Force Protection Battle Lab sponsored Remote Detection Challenge & Response (REDCAR) concept demonstration executed by the Air Force Robotics Lab (AFRL). The REDCAR used an MDARS PUV as the central robotic technology and expanded the concept to incorporate a smaller high speed platform (SCOUT) equipped with lethal, non-lethal and challenge components as an engagement platform and, in a marsupial configuration on the MDARS, a small UGV that can be deployed to investigate close quarters areas. The Family of Integrated Rapid Response Equipment (FIRRE) program further expands these concepts by incorporating and adapting other mobile/tactical force protection equipment with a more robust Unmanned Ground Vehicle into an "Expeditionary" configuration to provide the current force with a rapidly deployable force protection system that can operate in austere less structured and protected environments. A USAMPS/ MANCEN sponsored "FIRRE System Demonstration" in Iraq is scheduled to begin in FY '07.
Structural tailoring of engine blades (STAEBL)

Mathematical optimization is applied to the design of gas turbine fan blades. The automated procedure replaces the current manual process which requires experience and intuition on the part of the designer to achieve successful blade designs. The optimization procedure that is developed utilizes the COPES/CONMIN optimization code. Approximate vibration and stress analyses are used for the optimization process. Analysis recalibrations are achieved through the application of more detailed, refined analysis. Optimizations of a hollow titanium fan blade with composite inlays and of a superhybrid composite blade are demonstrated.
HEAVY VEHICLE SYSTEM FOR AUTOMATED PAVEMENT CRACK SEALING.

An automated crack sealing machine (ACSM) prototype has been developed to in order to: 1) minimise the exposure of workers to the dangers associated with working on a major highway; 2) considerably increase the speed of the operation; and 3) improve the quality and consistency of the resultant seal. Increasing the speed of the operation will in turn reduce the accompanying traffic congestion since lane closure times will decrease. Reduced traffic congestion alleviates numerous accompanying problems including air pollution, fossil fuel depletion, and loss of productivity. In order to satisfactorily seal cracks, the ACSM performs the following functions automatically: senses the occurrence and location of cracks in pavement; adequately prepares the pavement surface; prepares and dispenses the sealant; forms the sealant into the desired configuration. This paper describes the integrated vehicle system for automated crack sealing. This includes description of the ACSM architecture, support vehicle, system components, operation and performance specifications.
Parameter Identification of Ship Manoeuvring Model Based on Particle Swarm Optimization and Support Vector Machines

The method of system based manoeuvring simulation provides an effective way to predict ship manoeuvrability. Accurate determination of the hydrodynamic derivatives in the mathematical model of ship manoeuvring motion is vital to the prediction accuracy. A support vector machines (SVM) based approach is proposed in this paper. By analyzing the data from free-running model tests of KVLCC2 ship, the hydrodynamic derivatives in an Abkowitz model are identified. To diminish the parameter drift in the identification, a difference method is adopted to reconstruct the sample for identification. To obtain the optimized structural parameters in SVM, particle swarm optimization (PSO) method is incorporated into SVM. Predictions of manoeuvring motion are presented based on the regression model. Comparisons between the predicted results and the test results demonstrate the validity of the proposed methods. © 2013 ASME
The Condition Assessment of Distribution Transformer Based on Improved Analytic Hierarchy Process

It is very vital for the distribution transformer in the distribution system, crucially ensuring its reliable operation is, therefore, timely and accurately grasping the state of the transformer is very meaningful for guiding the condition maintenance of transformer and improving the operation reliability of distribution system. It is very difficult for AHP to inspect and adjust the consistency of judgment matrix, and its inspection standard lacks of scientific basis, so we put forward a fuzzy comprehensive evaluation method which uses five-demarcation method to establish the fuzzy complementary matrix on the condition assessment of distribution transformer. Through an example analysis, which proposed method is proved to be rationality and validity.

Chemical Demilitarization: Disposing of the Most Hazardous Wastes,

This country's aging stockpile of chemical warfare munitions require safe and economical disposal. These munitions present a unique challenge for demilitarization, since handling of both explosives and toxic material is required. The first full-scale munitions disposal facility is presently undergoing testing and systemization on Johnston Island. The technology developed for incorporation into the Johnston Atoll Chemical Agent Disposal System maximizes the use of automated equipment, provides the containment necessary to protect the worker and environment, and thermally destroys both the toxic fill and explosives from the munitions.
Localization of Lamb Wave Scattering Source Based on Time-Frequency Analysis

Considering the influence of Lamb wave dispersion on the precision of damage detection, a new detection method of scattering source based on time-frequency curves and ellipse localization method is proposed. Empirical mode decomposition(EMD) is used to decompose the scattering signal into finite narrowband signals, and a modified continuous wavelet transform(CWT) is further used to get the time-frequency distribution(TFD) of the detected signal, and the arriving time of different frequency component is estimated based on TFD. A series of location results can be obtained from different frequency components using ellipse localization method. The damage position can finally be estimated by synthesizing localization results at different frequencies. Experiments on aluminum plate are conducted to demonstrate the efficiency of the proposed method. EMD-CWT analysis can get precise time-frequency curves in highly dispersive low frequency band of A0 mode. The damage location results is more accurate and the influence from occasional factors can be suppressed by using the synthesized method.
Integrating procurement and operational innovations for construction industry development

Uncertainty of eventual outcomes coupled with a reluctance to embark upon potentially long learning curves, have militated against much‐needed holistic innovations in our instant‐results‐oriented construction industry. While sporadic initiatives towards new organizational and/or contractual arrangements have enabled incremental improvements in some scenarios, the increasing demand for step gains in construction industry performance levels evidently envisages a more solid launching pad with re‐engineered paradigmatic foundations. Initial investigations suggest that the foregoing desired goals may be achieved together. Finally, a conceptual model that coherently synergises these strategies for institutional and industry development is presented and discussed.
