Innovative Capabilities of the Agricultural Biotechnology Sector in Hungary

This study investigates how context-specific institutional factors affect innovative capabilities of the agricultural crop biotechnology sector in Hungary. Answering this question has involved three areas of research, into: the network of actors and its accommodation of technological characteristics; the sustained use of institutional arrangements which characterised the pre-transition science and innovation system; and, the difficulty of adapting to the regulatory environment in the post accession phase. The significance of this work results from the lack of current knowledge on the extent and survival of capabilities in this sector in Hungary. The study timing is also significant: This is a phase that demonstrates how the sector is surviving the economic crisis that accompanied transition and enduring the current political uncertainty surrounding national GM crop policy. The study uses qualitative methods, comprising a series of in-depth investigations. Data collection via interview and observation began in 2006. Data collection and analysis were guided by a theoretical framework emanating from national innovation systems and triple-helix perspectives. This thesis explores the challenges that are faced by an innovation system during economic transition. The thesis also contributes to the knowledge of science systems and how core science capabilities have contributed to the endurance of a sectoral innovation system. In conclusion the work finds that innovative capabilities in the Hungarian agri-biotech sector currently reside in the core competencies and activities of the science community in this sector and the networks they have created over time within and outside the country. Their future survival depends on the ability of the sector to adapt to the changing context. The institutions between actors and organisations are key to survival of capabilities and their ability to adapt. Institutions hold both the adaptive mechanisms for change and the legacies of the past which can help or hinder that change.
Supersonic Wind Tunnel Measurements of Static and Magnus Aerodynamic Coefficients for Projectile Shapes with Tangent and Secant Ogive Noses

Abstract : Wind tunnel tests have been conducted for a series of projectile configurations. The shapes tested include a three caliber secant ogive nose and three caliber tangent ogive nose configuration. The overall model length was fixed at 6 calibers for all configurations tested. Static and Magnus aerodynamic coefficient data were obtained at Mach numbers 2.0, 3.0 and 4.0 for angles of attack up to 10.0 deg. The data are presented in graphical form along with tabulations of the summary data. The tangent ogive nose produced a slight increase in the Magnus moment coefficient when compared to similar secant ogive configurations. The boattail configuration, when compared to the cylinder shapes, was found to increase the Magnus moment; however, this effect was shown to decrease with increasing Mach number.
Status of the Short-Pulse X-ray Project (SPX) at the Advanced Photon Source (APS)

The Advanced Photon Source Upgrade project (APS-U) at Argonne includes implementation of Zholents’* deflecting cavity scheme for production of short x-ray pulses. This is a joint project between Argonne National Laboratory, Thomas Jefferson National Laboratory, and Lawrence Berkeley National Laboratory. This paper describes performance characteristics of the proposed source and technical issues related to its realization. Ensuring stable APS storage ring operation requires reducing quality factors of these modes by many orders of magnitude. These challenges reduce to those of the design of a single-cell SC cavity that can achieve the desired operating deflecting fields while providing needed damping of all these modes. The project team is currently prototyping and testing several promising designs for single-cell cavities with the goal of deciding on a winning design in the near future. Here
Analysis of tremor in handicapped people for the design of computer interfaces

In this paper we present a set of tools that help in building interfaces for users who exhibit uncontrolled tremor in their upper limbs. These tools, which use a standard sketch board as sensing and final interface device, permit the logging of movement information while the user performs some simple tasks. Several movement analysis tests are proposed and applied to a small group of users. These preliminary experiments were conducted as a phenomenological study of these users. Although the sample size is small, test results are studied in detail and several important conclusions are obtained. Furthermore, useful data and procedures for building usable interfaces are also presented.
The carbon dioxide signal from the COVID-19 lock-down

Two unintended experiments provide insight into the role of anthropogenic emissions in the global carbon cycle. One was the temporary reduction in emissions during the COVID-19 lock-down. The other was the emission of a radioactive isotope of carbon during the testing of nuclear weapons in the 1950s and the abrupt cessation of these tests in 1963. Together they imply the existence of two distinct reservoirs which exchange carbon with the atmosphere, viz.: the mixed layer and the deep ocean. Exchanges with the former are noisy because they are influenced by sea surface temperature which, in turn, depends on local weather conditions. They completely mask any variations caused by the COVID-19 lock-down. Exchanges with the latter are steady, long-term and uninfluenced by the weather. They result in half the carbon content of the atmosphere and mixed layer being replaced every eleven years.
Reflective Dialog Journals: A Tool for Developing Professional Competence in Novice Teachers.

This study focuses on the use of a mentoring protocol, the reflective dialogue journal, to develop professional competencies for pre-service teachers within a school-university partnership. To examine the effectiveness of the reflective dialogue journal protocol and the processes employed by mentor teachers to assist pre-service teachers with developing professional competencies, this study utilized a qualitative research method and analyzed the reflective dialogue journals written by 21 pairs of mentor teachers and pre-service teachers over a period of 12 weeks. Results show that keeping reflective dialogue journals benefits both the mentor teachers and the pre-service teachers, allows mentor teachers to identify areas of concern by pre-service teachers, and provides a wide range of mentoring strategies for mentor teachers. Findings indicate this easy-to-use, evidence-based tool can be readily incorporated into mentoring programs to enhance reflective practice and provide structured mentoring opportunities. NAPDS Essential(s) Addressed: #4/A shared commitment to innovative and reflective practice by all participants; #5/Engagement in and public sharing of the results of deliberate investigations of practice by respective participants.
Advances in Systems and Technologies Toward Interopoerating Operational Military C2 and Simulation Systems

Abstract : Since 2003, a community focused on interoperation of command and control (C2) systems with simulation systems has developed a new area of technology known as Battle Management Language (BML). Their vision is a future where military organizations can link their C2 and simulation systems, without special preparation, in support of coalition operations. This paper reports on systems and technology developments of the last ten years, which have made great progress toward achieving that vision, as part of the work of the NATO Modeling and Simulation Group (MSG). The technology used in these projects to achieve effective operational use of C2 with interoperating simulations is based around a shared understanding of information, defined in an XML schema and implemented in each participating system. Interoperation is facilitated by an agreed upon definition of the information to be shared, recently supported by two coordinated standards: Military Scenario Definition Language (MSDL) and Coalition Battle Management Language (C-BML). The paper will review the history and current status of systems and technologies, including the standards, C2 systems, simulation systems, and server systems employed. The conclusion addresses next steps to achieve operational deployment, based on emerging commercial products and military systems.
NUMERICAL STUDY OF SALTATING MODE OF BEDLOAD TRANSPORT IN TURBULENT ROUGH CHANNEL FLOW CONSIDERING SHAPE FACTORS

Saltating mode of sand particle transport, compared with rolling and sliding modes, was regarded as the most dominant mechanism of bedload transport in a fluvial stream by earlier investigations. In this paper, considering various shape factors of natural sediments, a numerical simulation of sediment particle saltation by streamflow are presented. At first, a roughness closure method is employed to generate a rough sediment bed. The large-eddy simulation (LES) is used to simulate the turbulent channel flow condition. The Newton’s second law and Euler’s equation are applied to calculate the forces and torques acting on the saltating particles respectively to determine their state of translational and rotational motion. Then, the mathematical model was validated by the experimental data from Niño and García (1998a). The computational saltation statistics for different shaped particles such as saltation lengths, heights, streamwise velocities, angular velocities and resting time are analyzed and compared. Finally, bedload transport rates are estimated as the product of the particle velocity, the saltation height and the bedload concentration which agreed well with previous classical formulas and experimental data.
E-values for effect heterogeneity and approximations for causal interaction

Abstract Background Estimates of effect heterogeneity (i.e. the extent to which the causal effect of one exposure varies across strata of a second exposure) can be biased if the exposure–outcome relationship is subject to uncontrolled confounding whose severity differs across strata of the second exposure. Methods We propose methods, analogous to the E-value for total effects, that help to assess the sensitivity of effect heterogeneity estimates to possible uncontrolled confounding. These E-value analogues characterize the severity of uncontrolled confounding strengths that would be required, hypothetically, to ‘explain away’ an estimate of multiplicative or additive effect heterogeneity in the sense that appropriately controlling for those confounder(s) would have shifted the effect heterogeneity estimate to the null, or alternatively would have shifted its confidence interval to include the null. One can also consider shifting the estimate or confidence interval to an arbitrary non-null value. All of these E-values can be obtained using the R package EValue. Results We illustrate applying the proposed E-value analogues to studies on: (i) effect heterogeneity by sex of the effect of educational attainment on dementia incidence and (ii) effect heterogeneity by age on the effect of obesity on all-cause mortality. Conclusion Reporting these proposed E-values could help characterize the robustness of effect heterogeneity estimates to potential uncontrolled confounding.
EXPLORING PRESENT ABILITY: A COLLOSTRUCTIONAL APPROACH

The paper investigates two constructions commonly thought to be semantically equivalent, S can V and S be able to V. Both modal can and semi-modal be able to are used to express ability that could be described as either mental or acquired accomplishment, pertaining to past or present. The diﬀerence between them is typically denoted as general ability or that someone managed to do something on a particular occasion. If not limited by the main verb (e.g. there is a constraint against can after another modal verb), can and be able to are mostly interchangeable. Starting from the premise that every construction carries meaning which is dependent on the meaning of lexical elements occurring in that construction, the aim is to shed light on the usage of the two verb constructions and the degree of their interchangeability by examining their complements. To compare and contrast the two constructions, we rely on a corpus-based and quantitative method of collostructional analysis (Gries and Stefanowitsch 2004), or specifically on distinctive collexeme analysis which allows us to determine if the V slot in the construction is preferred by or restricted to particular lexemes. As S can V and S be able to V are highly attested in the corpus, the research is restricted only to their meaning of the present ability
Superconducting THz mixers based on MgB2 film

Superconducting NbN hot electron bolometer (HEB) mixers are widely used in terahertz radio astronomy. Such mixers have superior performance compared to SIS and Schottky diode mixers at frequency above 1THz. However, their drawback is a limited IF bandwidth. Therefore, as radio astronomy advances towards higher frequencies, mixers with even wider gain bandwidth are required. The gain bandwidth of the HEB mixers is determined by two consequent processes in the electron energy relaxation: the electron phonon interaction and the phonon escape into the substrate with corresponding time constants for each process. The electron-phonon interaction time is inversely dependent of the electron temperature of the film which is close to the critical temperature of the superconductor. The escape time is dependent of the film thickness. Materials with higher critical temperature and shorter electron relaxation time are needed to improve the IF bandwidth. The discovery of the superconductivity in the intermetallic compound magnesium diboride (MgB2) has generated a great interest in this research field. The high critical temperature and the short electron phonon interaction time make the MgB2 very attractive for HEB mixers fabrication aiming for better HEB mixers performances. In this thesis, novel terahertz HEB mixers based on magnesium diboride thin films are presented. MgB2 HEBs integrated with spiral antenna were fabricated, characterized and studied. The gain bandwidth was investigated with respect to the thickness and the critical temperature of the film. A gain bandwidth of 1.3GHz, 2.3GHz and 3.4GHz corresponding to a mixer time constant of 130 ps, 70 ps and 47 ps was measured in 30 nm, 15 nm and 10 nm MgB2 films, respectively. Another important figure of merit for receivers is the noise temperature which is influenced by several factors such as the dimension of the HEB and the critical current. For HEB mixers made from 10 nm MgB2 film the lowest mixer noise temperature was 600K measured at 2K bath temperature and 600GHz local oscillator (LO) frequency. Finally, using the two temperature model the experimental data were analyzed and the electron phonon interaction time, τe-ph of 7 to 15 ps, the phonon escape time, τesc of 6 to 42 ps and the specific heat ratio, ce/cph of 1.35 to 9 ps were extracting giving the first model for HEB mixers made of MgB2 films. Based on this research a gain bandwidth as large as 8-10GHz has been predicted in very thin MgB2 films.
AN OPEN INNOVATION APPROACH TO THE RADICAL INNOVATION PROCESS : An Analysis of the Management of the Process of Radical Innovation in an Open Innovation Paradigm

This thesis amends some existing theoretical gaps and an overall lack of empirical studies regarding the ways RD the actual extent to which it is used, and the ways the managers use it. Our results reveal that the extent varies from an early peak, an in between Open Innovation chasm and a final increase. Furthermore, our studies also show that the main ways the managers use OI are; exploitation and creation of revenue streams, knowledge leveraging and integration, and finally to create superior products using broad knowledge networks.
Cost and time overruns: Business as usual; from failure to success projects by steering and intervening in building processes

Cost and time overruns are common but unacceptable. Research on causes and indicators has been done but cost and time overruns still take place. The focus on success projects in relation to management methods should give new perspectives. This research will focus on management tools to steer and/or intervene in the process to prevent or decrease cost and time overruns in future projects.
Air Force Officer Qualifying Test (AFOQT): Forms Q Development, Preliminary Equating and Operational Equating

Abstract : Air Force Officer Qualifying Test (AFOQT) Forms Q1 and Q2 were developed to be highly similar to the just previous Forms P1 and P2 in test content and length, item difficulty and discrimination, and stylistic features. Approximately half the items were new and half were from Forms P. Forms Q1 and Q2 were preliminarily equated on Air Force Academy students, Reserve Officer Training Corps cadets and Officer Training School cadets. Scoring tables were developed and AFOQT Forms P1, Q1, and Q2 were administered operationally to over 3000 cases per form. Equating tables were accomplished using the data from these actual applicants. It was concluded that these scoring tables should be implemented to make Air Force Officer selection decisions.
Basic helicopter aerodynamics. [Third edition]

Basic Helicopter Aerodynamics is widely appreciated as an easily accessible, rounded introduction to the first principles of the aerodynamics of helicopter flight. Simon Newman has brought this third edition completely up to date with a full new set of illustrations and imagery. An accompanying website www.wiley. com/go/seddon contains all the calculation files used in the book, problems, solutions, PPT slides and supporting MATLAB® code. Simon Newman addresses the unique considerations applicable to rotor UAVs and MAVs, and coverage of blade dynamics is expanded to include both flapping, lagging and ground resonance. New material is included on blade tip design, flow characteristics surrounding the rotor in forward flight, tail rotors, brown-out, blade sailing and shipborne operations. Concentrating on the well-known Sikorsky configuration of single main rotor with tail rotor, early chapters deal with the aerodynamics of the rotor in hover, vertical flight, forward flight and climb. Analysis of these motions is developed to the stage of obtaining the principal results for thrust, power and associated quantities. Later chapters turn to the characteristics of the overall helicopter, its performance, stability and control, and the important field of aerodynamic research is discussed, with some reference also to aerodynamic design practice. This introductory level treatment to the aerodynamics of helicopter flight will appeal to aircraft design engineers and undergraduate and graduate students in aircraft design, as well as practising engineers looking for an introduction to or refresher course on the subject.
New optimized technique for mechanical control of Elymus repens

Elymus repens (coach grass) is traditionally controlled by repeated and prolonged stubble cultivation. However, the efficacy is strongly depending on weather and secondly on the exposure of rhizomes. The shorter the required period of cultivation stays the more compliance with the objective in organic farming where farmers aim at minimizing leaching of nutrients by keeping the soil plant-covered during autumn and winter. Effective technique and strategies for uprooting, exposing and destroying Elymus repens are needed. In a Danish organic research project the focus is on technological solutions for uprooting, exposing and destroying of the rhizomes within a short time span. Machines of standard type, modified machines and machines constructed for other purposes have been studied. The results show that it is difficult to achieve a high percentage of uprooting when using machines giving a high area capacity, e.g. spring loaded tine cultivator and rigid tine cultivator with modified spike discs at the rear.
A Formulation of the Air 6000 Problem from a Joint Systems Perspective

Abstract : The Air 6000 Project seeks to provide Australia with a new aerospace combat capability. The need for such a new capability arises from the impending obsolescence of key assets providing Australia's existing aerospace combat capability. The achievement of a high-quality solution to this problem will require support to decision-making for complex systems-of-systems which involve the interest of multiple stakeholder groups. A formulation of the problem, and some possible techniques for its solution are described in this report.
A multi-camera image acquisition system and its application for the investigation of flow related events

A previously (at ISFV11) presented high-speed video stroboscope developed at the Institute of Aerodynamics and Flow Technology of German Aerospace Center has been improved and extended to a high-resolution, multi-camera recording system. This system allows for the investigation of fast repetitive, e.g. periodic, phenomena and provides a real-time, slow-motion display of these events with simultaneous frame recording. Non-repetitive events can be imaged with the variable framing rate limited by the properties of the applied cameras. This system has been successfully used in various applications as the visualization of micro- and macroscopic flows, diagnostics of fast running machines as turbines and engines (fuel injection, combustion), marine propellers (cavitation), medicine (larynx diagnostics) and zoology (study of the insect fly). It has been also used for the investigation of the flap gap width during the Airbus A340-400 flight tests in the EU-Project “AWIATOR”. Especially for this project, a number of dedicated features have been implemented to the system.
Modeling and analysis of process complexity and performance in mixed model assembly systems

Mixed model manufacturing systems are increasingly being used to meet global competition by providing a broad variety of products to customers. The increase of product variety adds more complexity to production processes, thus leading to a negative effect on the performance of production processes. Therefore, it is of great interest to effectively measure such complexity, and to quantify its effect on manufacturing system performance. In this paper, a set of complexity metrics are proposed for measuring the complexity of different elements in a manufacturing system; these metrics were achieved by constructing a linkage with communication system‟s framework. Different from existing complexity measures defined in the literature, this paper is the first to consider production quality into the measure of the process capability for handling the complexity induced by the input demand variety. Examples are given in the paper to discuss different properties of the defined metrics and their potential applications.
