NASA Global Hawk: Project Overview and Future Plans

Abstract – The National Aeronautics and Space Administration (NASA) Global Hawk Project became operational in 2009 and began support of Earth science in 2010. Thus far, the NASA Global Hawk has completed three Earth science campaigns and preparations are under way for two extensive multi-year campaigns. One of the most desired performance capabilities of the Global Hawk aircraft is very long endurance: the Global Hawk aircraft can remain airborne longer than almost all other jet-powered aircraft currently flying, and longer than all other aircraft available for airborne science use. This paper describes the NASA Global Hawk system, payload accommodations, concept of operations, and the scientific data-gathering campaigns. Keywords: Earth science, Remote sensing, Global Hawk, Unmanned aerial system, High-altitude long-endurance. 1. INTRODUCTION The National Aeronautics and Space Administration (NASA) Dryden Flight Research Center (DFRC) (Edwards, California, USA) has acquired three Advanced Concept Technology Demonstration (ACTD) RQ4A Global Hawk (Northrop -Grumman Corporation, Los Angeles, California, USA) aircraft from the United States Air Force (USAF). Two of these pre-production Global Hawk aircraft are being used to support NASA and the National Oceanic and Atmospheric Administration (NOAA) science customers as well as additional customers who require access to a high-altitude, long-endurance system. The DFRC and the Northrop Grumman Corporation (NGC) have entered into a five-year Space Act Agreement that includes the development and operation of the NASA Global Hawk system. The NGC is providing technical, engineering, maintenance, and operations support, as well as portions of the ground control station. The DFRC is providing facilities; flight approval responsibility; flight operations coordination; and maintenance, operations, and project staffing. The NGC and NASA share equal access to the NASA Global Hawk system for the duration of the Space Act Agreement.
EVALUASI KONVERTER DC – DC TIPE CUK PADA SISTEM FOTOVOLTAIK TIPE STAND ALONE DENGAN MAXIMUM POWER POINT TRACKING (MPPT) MENGGUNAKAN METODE ADAPTIVE NEURO FUZZY INFERENCE SYSTEM (ANFIS)

Abstrak Potensi energi matahari di Indonesia dapat dimanfaatkan sepanjang hari, hal ini sangat menguntungkan untuk membangkitkan energi listrik dengan menggunakan sistem fotovoltaik. Permasalahan utama pada penggunaan fotovoltaik adalah pembangkitan tenaga listrik yang rendah pada kondisi radiasi yang rendah dan besarnya daya listrik yang dibangkitkan berubah secara berkala seiring dengan perubahan cuaca dan suhu. Maximum Power Point Tracking (MPPT) adalah peralatan yang digunakan untuk meningkatkan rasio daya modul fotovoltaik. Maximum Power Point Tracking (MPPT) digunakan untuk mencari point (titik) maksimum dengan cara menaikkan dan menurunkan tegangan menggunakan konverter cuk, maka penggunaan Maximum Power Point Tracking (MPPT) sangat dibutuhkan untuk meningkatkan rasio daya keluaran pada sistem fotovoltaik. Pada penelitian ini digunakan metode Adaptive Neuro Fuzzy Inference System (ANFIS) untuk mengevaluasi proses kinerja fuzzy logic pada sistem fotovoltaik tipe stand alone dalam perangkat Maximum Power PointTracking (MPPT), sehingga dapat meningkatkan rasio daya keluaran modul fotovoltaik. Kata kunci : fotovoltaik, MPPT, metode ANFIS Abstract The solar energy in Indonesia can be used for almost about 10 hours in a daylight; therefore it is very useful to generate an electricity power by using photovoltaic system. The main problem in using photovoltaic systemis that all depends on the weather and the temperature of the daylight; furthermore the hot sunny day will be able to produce high solar radiation which is able to generate high electricity power. On the other hand the cloudy day will be able only to produce low solar radiation which is only able to generate low electricity power as well. Maximum Power Point Tracking (MPPT) is a tool used to increase the power ratio of the modulphotovoltaic. Maximum Power Point Tracking(MPPT) is used to find the maximum point by increasing and reducing the voltage which use cuk converter, so the uses of Maximum Power Point Tracking (MPPT) is badly needed to increase output power ratio in photovoltaic system.For this research, Adaptive Neuro Fuzzy Inference System(ANFIS) method is used to evaluate process of stand alone photovoltaic system in the set of Maximum Power Point Tracking (MPPT); therefore it can increase the output of power rasio.in photovoltaic modul.

Overriding individual harmonic current control with fast dynamics for UPS with nonlinear loads

When an UPS is loaded with nonlinear loads, significant voltage distortion in the output voltage might occur which is not within the limits of requirements specified by standards. A new control which was proposed for active-filters is adapted to UPS and it makes sure that the inverter supplies all the load harmonic currents so that the output filter capacitor is not loaded with these harmonics and thereby obtaining a very clean sinusoidal output voltage. In the proposed scheme, the PI current controller in the fundamental synchronous reference frame (FSRF) controls the fundamental DC currents and as well as the harmonic references which appear as AC quantities in this frame with fastest dynamics as possible. This controller has zero steady state error for the fundamental DC references and a finite magnitude and phase error for AC references which increases with the order of harmonics. Over-riding individual harmonic current controllers are implemented in their respective reference frames which correct the respective harmonic reference in FSRF such that the converter current is equal to that of load current at that harmonic. Thus excellent dynamic and steady state performance is achieved. Both closed loop and open loop approaches are presented. A 50 kVA lab prototype is built with both three and four leg inverter topologies and the results are given for the same.
THE EMPEROR'S NEW CLOTHES: YES, THERE IS A LINK BETWEEN ENGLISH LANGUAGE COMPETENCE AND ACADEMIC STANDARDS

Australian universities have struggled to compensate for funding cuts by taking in large numbers of full-feepaying international students. Concern is mounting about falling standards and the growth of plagiarism. The author interviewed 14 academics from 10 universities and found that all were concerned about the inadequate English of many international students. Most reported pressure to pass such students despite poor work, and to overlook plagiarism. Where academics did report plagiarism they found the process timeconsuming and often futile.
A versatile procedure for calculating heat transfer through windows

Advances in window technologies and the desire to standardize the reporting of standard window heat transfer indices have necessitated the development of a comprehensive analytical procedure for calculating heat transfer through windows. This paper shows how complete window heat transfer can be considered as the area-weighted sum of the three window component areas: the center-of-glass area, the edge-of-glass area, and the frame area. Algorithms for calculating heat transfer through each of these areas and for combining these to calculate total window indices are presented. 36 refs., 5 figs., 6 tabs.
Designing LoRaWAN Network For Unbiased Communication Between Nodes and Gateway

Proper cell designing is required to achieve a target system performance in Long Range Wide Area Network (LoRaWAN). This paper addresses a suitable selection of network designing parameters problem, such as the dimension of different spreading factors’ annuli (zones or SF boundaries) in a LoRaWAN cell. We propose a mathematical framework for designing the LoRaWAN network. The main objective is to ensure that distributed end devices in the network can have the same success probability, irrespective of the spreading factor usage and their locations, unlike Equal Area Based (EAB) based network. We further enhance the performance of the network based on the proposed dimensions by adopting the k-tolerance algorithm. When the network follows the proposed dimensions, simulation results show an improvement in overall success probability over the traditional EAB scheme. In the later part of the paper, we address urbanization issues that degrade the system performance. In our approach to recoup the degradation in the system performance, we implement k−tolerance algorithm in the network.
Construction patents and university-industry research interaction: An analysis of Nordic region data

Purpose – In the context of university-industry interaction, little is known about construction patents. The purpose of this paper is to explore this aspect of construction innovation systems. Design/methodology/approach – After a review of studies of academic interaction with the construction sector, applications for construction patents in Denmark, Finland, Norway and Sweden for 2006-2010 were analysed. References to academic publications in US patent applications in three relevant classes were identified. Findings – References to university interaction occur in construction patents, but only seldom and not for mechanical devices. Country differences in patent legislation, such as legal protection for utility models and concerning university ownership of patents, have little effect on construction patenting. Research limitations/implications – Further analyses of construction-specific relations between types of university-industry interaction are needed, as well as empirical studies of other regions. Pr.

Teaching and assessment of students taking a first year, Level 7 subject: analysis and actions

This contribution critically analyses the teaching and assessment strategies used on the core Electrical Systems subject in the first year of a three-year, Level 7, degree programme in Electrical Engineering at Dublin Institute of Technology. The author has the responsibility for development and instruction in the subject since 2004. In the 2004-5 and 2005-6 academic years, the didactic teaching approach and the assessment strategy ensured good educational outcomes. This was not the case in the 2006-7 academic year. The contribution will analyse the reasons for this, taking an evidence-based approach (i.e. analysing the assessment data in detail). Two conclusions that are drawn are that students have reasonable breadth of knowledge of the basic material, but knowledge depth is limited, and that students perform better in laboratories and project work than in examinations. Subsequently, the actions taken to improve student learning in the 2007-8 academic year will be detailed, and some preliminary analysis of the resulting assessment data will be provided.
BAYESIAN DECISION THEORY IN SIMILARITY CRITERIA USED IN RANGE IMAGES SEGMENTATION

To obtain a segment image is still not possible. Typically, results obtained by computer programs show over-segmentation and not well-defined edges. Most of these difficulties are believed to be due to similarity criteria used by segmentation algorithms. In this paper, there is an analysis of similarity criteria most used in literature and an analysis of criteria based on Bayesian decision theory.
Validation of Current and Alternative Armed Service Vocational Aptitude Battery (ASVAB) Area Composites, Based on Training and Skill Qualification Test (SQT) Information on Fiscal Year 1981 and 1982 Enlisted Accessions

Abstract : This report describes a large scale research effort to validate and improve the ASVAB aptitude area (AA) composites now used by the Army to select and classify enlisted personnel. Data were collected from existing Army sources on over 60,000 soldiers and over 60 MOS. The research had three major components: First, the composites now being used by the Army were validated. Second, a new set of composites were derived empirically; and finally, both sets were compared on the basis of predictive validity, differential validity, and possible prediction bias. Both sets of composites were found to perform well, with the alternative set of four composites doing slightly better than the nine now in operational use.
Existing Prototyping Perspectives: Considerations for service design

With new design disciplines that challenge the borders of design practice and inquiry comes new possibilities for prototyping techniques and approaches. The basis for such an evolution is a firm understanding of the existing knowledge generated in design and the challenges posed by new design disciplines, such as service design. This study identifies a framework of perspectives for prototyping to reveal what the existing toolbox of prototyping contains based on a literature overview. Going through published literature from the early 1980s and onward, the framework is constructed using the following perspectives; purpose, fidelity, audience, position in the process, technique, and representation. These perspectives make knowledge about prototyping explicit and summarise contemporary approaches. Based on current challenges and characteristic attributes of service design the framework is then reconstructed to better cater to design for services. The conclusions are that validity and author are two perspectives that complement the existing framework, and that prototyping so far does not support a holistic approach to prototyping services.
United States Airline Transport Pilot International Flight Language Experiences, Report 2: Word Meaning and Pronunciation

In 1998, the International Civil Aviation Organization (ICAO) took a heightened interest in the role of language in airline accidents. Its Air Navigation Commission was directed to strengthen relevant ICAO provisions concerning language requirements. Member states agreed to take steps to ensure air traffic control (ATC) personnel and flight crews involved in flight operations in airspace where the use of the English language is required were proficient in conducting and comprehending radiotelephony communications in English. Since then, ICAO developed its English Language Proficiency (ELP) requirements and urged its members to document their ELP test implementation plans by March 8, 2008. Until all ATC personnel and flight crews involved in flight operations obtain a passing level of ELP, the language-based problems international pilots face is not known. This report is a compilation of written responses and comments by a small focus group of 48 U.S. pilots of their difficulties in international operations. The focus group consisted of 12 international U.S. pilots each from American, Continental, Delta, and United Airlines. Each focus group met with two interviewers to discuss their language experiences flying into countries where English may or may not be the local or national language among its radio operators, controllers, and pilots. In this report, the pilots’ responses to questions 24-30 and their comments from discussions of those questions with interviewers are presented as a compiled narrative. The pilots’ responses had eight major thrusts: (1) Once pilots get past the controller’s accented English, understanding is not a problem during routine operations; (2) the lack of standardized pronunciation of NAVAIDs, waypoints, intersections, etc. complicates understanding what was said; (3) Currency in flight time in the theater of operation is critical to understanding accented English and will influence how easily controllers from different countries are understood; (4) Poor radios and transmission quality contribute to the unintelligibility of some controller transmissions; (5) Variations in pronunciation can detract from flying, as pilots must listen intently to clearances; (6) Training is essential for crews lacking currency going into a foreign country; (7) Differences associated with U.S. and ICAO phraseology need to be resolved and procedural ambiguities eliminated; and (8) Technological advancements such as controller pilot datalink communications (CPDLC) and automatic dependent surveillance (ADS) can mitigate some of the problems associated with accented English. The authors offer 10 recommendations to improve communication practices, which include development of a standardized phraseology, its presentation, delivery technique, and meaning, training, and implementation of ICAO’s ELP by all member states.
IRTAD - INTERNATIONAL ROAD TRAFFIC AND ACCIDENT DATABASE (STAND: 1993)

Es sind Daten aus allen OECD-Mitgliedslaendern enthalten. Der Hauptteil der Datenbank umfasst derzeit ca. 240 Variablen. Fuer jedes Land sind fuer 1965 und ab 1970 unter anderem folgende Datengruppen vorhanden: Bevoelkerungszahlen nach Altersgruppen; Bestaende der einzelnen Kraftfahrzeugklassen; Fahrleistungen nach Strassennetzbereichen und Fahrzeugklassen; Anzahl der Unfaelle mit Personenschaden; Anzahl der Verkehrstoten; Strassennetzlaengen nach Netzbereichen; Verkehrsmittelwahl; Risikogroessen (zum Beispiel Getoetete, Schwerverletzte). Anhand der vorhandenen Variablen lassen sich weitere Werte errechnen. Die Datenqualitaet sowie die Verfuegbarkeit der neuesten Daten ist gesichert.
The coupling between calcaneal adduction and tibial rotation: a framework for a novel motion control footwear design

touchdown and a greater initial ankle plantar flexion range of motion until the foot is flat. Indeed, Gerritsen et al. (1995) supposed that the eccentric contraction of tibialis anterior muscle following a rearfoot landing acts on the absorption of impact energy. A forward progression of strike index does not automatically lead to a decrease of LR and it seems that extreme FATD in forefoot or rearfoot landing are needed in order to reduce LR.

CHARACTERISTICS OF SITTING POSTURES IN EATING AND DRINKING SPACES

In this research, people's sitting postures in various types of eating and drinking spaces were observed, and their characteristics and related factors were analyzed. The principle results are summarized as follows.1. More people tended to bend forward in fast-food restaurants, and more people tended to bend backward in izakaya (Japanese-style bars). Men tended to bend forward more than women in izakaya and restaurants, on the other hand, women tended to bend forward more than men in cafes.2. Younger people tended to bend forward in fast-food restaurants more than older people, and older people tended to bend forward in izakaya more than younger people.3. People in conversation tended to put their elbows on the tables more than people who were not talking, and people who were not eating tended to put their elbows on the tables more than people who were eating.4. People in bright spaces tended to bend forward more than people in dark spaces, and people in noisy spaces tended to put their elbows on the tables more than people in quiet spaces.
Software security for a network storage service

In 1991, Sandia National Laboratories acquired a Network Storage Service (NSS) as a result of a fully competitive procurement. The Network Storage Service, which provides access to over a terabyte of data storage in a two-tiered hierarchy, had minimal software security features. Before the NSS could be placed into production, it had to be accredited by the Department of Energy, Sandia's accrediting authority. Sandia was faced with implementing security features to allow the NSS to be operated in its secure computing network, which is a single security clearance, multiple data security level environment. This paper describes the software security design alternatives that were considered and what was ultimately implemented.
Repertory grid, laddering e análise de conteúdo: uma abordagem psicométrica para entender profissionais de tecnologia da informação

A major challenge when researching on people relates to how reliable information can be retrieved from them. It is a matter of how to access what is literally inside people’s mind. Access is limited by the cognitive screening process that mediates human interaction, as well as by human rhetoric. We apply repertory grid, laddering and content analysis as an integrated psychometric approach to contrast two sets of constructs: a set of theoretically based constructs about the management of information technology professionals who work in customer teams, and a set of constructs that lie behind those professionals’ cognition in the particular case of implementing enterprise-wide systems (ERP). Results confirm the effectiveness of such a methodological approach to accurately reveal cognitive phenomena and to better understand the information technology workforce.
A three-stacked patch antenna using high-dielectric ceramic material substrate

The design and analysis of a new three-stacked patch antenna on aluminum oxide ceramic material substrate are presented in this article. Using high-dielectric material substrate, the overall size of the antenna is appreciably reduced without compromising the performance result of the antenna. The proposed antenna is designed and studied using commercially available finite element method–based high-frequency electromagnetic solver from ANSYS Corporation. From the result, it is observed that in the operating frequency range from 16.20 to 19.31 GHz (voltage standing wave ratio < 2), a wide range of bandwidth of 3.09 GHz and gain of 7.05 dBi at a resonant frequency of 17.20 GHz is achieved. It is also found that at the entire operating frequency band, the average gain is 3.5 dBi and the radiation efficiency is from 84% to 89%. The proposed antenna is fit for part of Ku-band and Ka-band applications.
Digital circuits using self-shunted Nb/NbxSi1-x/Nb Josephson junctions

Superconducting digital circuits based on Josephson junctions with amorphous niobium-silicon (a-NbSi) barriers have been designed, fabricated, and tested. Single-flux-quantum (SFQ) shift registers operated with ±30% bias margins, confirming junction reproducibility and uniformity. Static digital dividers operated up to 165 GHz for a single value of bias current, which was only marginally slower than circuits fabricated with externally shunted AlOx-barrier junctions having a comparable critical current density of 4.5 kA/cm2. In comparison, self-shunted a-NbSi junctions enabled a doubling in circuit density. This and their relatively thick 10 nm barriers could increase the yield of complex SFQ circuits.
