How we re going about it : Teachers Voices on Innovative Approaches to Teaching and Learning Languages

"How we're going about it" provides a space for teachers' voices in the nexus between research and practice by outlining specific cases of innovative approaches to language teaching and learning as they have been applied in the classroom. The volume includes descriptions of some of the most representative recent work and practice in the field while at the same time covering a wide geographic scope. The case descriptions help synthesize research and teaching practice in a way that is accessible to busy teachers, teacher trainers or anyone interested in language development. Each chapter focuses on a similar approach taken by teachers and researchers from different countries and while the book contains contributions from some well-known authors, it also includes contributions from lesser-known practitioners who merit recognition of their innovative practices. This book is an important contribution to language teaching and learning for several reasons. It deals with educational innovation at various levels of education (young learners, primary, secondary, tertiary); it deals with perspectives from different areas of Europe and beyond; and it provides examples of grass-roots experiences being carried out by real teachers in real classrooms and is honest about the problems faced when implementing educational changes. It is therefore a book about authentic experiences with both a theoretical and problem-solving base, experiences which in turn make an important contribution to the underlying theories described herein.
Effect of Internal Solitary Waves on Mine Detection in the Western Philippine Sea East of Taiwan

Abstract : Upper layer temperature in the western Philippine Sea near Taiwan was sampled using a coastal monitoring buoy with fifteen thermistors attached from July 28 August 7, 2005. Internal waves and internal solitons (IS) were identified using the empirical orthogonal function analysis. Without the IW and IS, the power spectra, structure functions, and singular measures (representing the intermittency) of the temperature field satisfy the power law with multi-scale characteristics at all depths. The IW does not change the basic characteristics of the multifractal structure. However, the IS changes the power exponent of the power spectra drastically, especially in the low wave number domain. It breaks down the power law of the structure function and increases the intermittency parameter. The physical mechanisms causing these different effects need to be further explored further. The Comprehensive Acoustic Simulation System was applied to determine how the IS affect the mine detection by computing the transmission loss (TL) and the ray traces of range-dependent and range-independent cases during the IS period. The maximum TL difference is 20 dB. As a result, the mine detection probability will dramatically be reduced to 1% of the original detection probability.

A Flight Dynamics Helicopter UAV Model For A Single Pitch-Lag-Flap Main Rotor: Modeling & Simulations

Problem area The main objective of this paper is twofold, first we derive the coupled flap-lag equations of motion for a rigid articulated Pitch-Lag-Flap (PL-F) rotor, with hinge springs and viscous dampers, for both CW and CCW rotating main rotors, with all hinges physically separated. The equations are obtained by the Lagrangian method. The flap-lag equations of motion are valid for small flap, lag, and pitch angles. Further the exact tangential and perpendicular blade velocity expressions are used, hence full Report no. NLR-TP-2010-286-PT-1
Engine Life Extension through the Use of Structural Assessment, Non-Destructive Inspection, and Material Characterization

Abstract : For over twenty years, the USAF has had a life extension program for major rotating hardware, such as rotors, seals, and shafts. This program was called Retirement-For-Cause (RFC). Damage tolerance philosophies are essential to this lifting technique. Damage tolerance has been applied to all new engine programs as part of the Engine structural Integrity Program (ENSIP) within the USAF since 1984. An essential element of ENSIP and RFC is non- destructive evaluation (NDE). Not only is there a need for NDE equipment but also the quantification of the NDE system/process. The RFC program provided state of the art NDE equipment and software to enable complex inspections.
Reverse dictionary

In this project, we produce a reverse dictionary, which allows one to find a word that they can’t remember, by describing its meaning. We compare multiple architectures to find the most efficient implementation of a reverse dictionary, in terms of accuracy, computational workload and speed. We observe that an encoder-decoder model based on a BERT encoder coupled with either linear decoder layers or an LSTM decoder layer yield the best results
Design and control of a DC collection grid for a wind farm

In this thesis, the internal DC collection grid for a wind farm is investigated regarding the design, losses and dynamic operation for both normal operating conditions and for different fault conditions. The main advantage for the DC collection grid is the considerably lower weight of the 1 kHz transformers in the DC/DC converters compared to the equivalent 50 Hz transformers. For a wind farm with 48 2.3 MW wind turbines, and a DC/DC converter in each turbine as well as a main DC/DC converter for the whole wind farm, the losses for the DC system are 3 % of the transferred power, which is similar to the losses of a corresponding AC collection grid. For the dynamic control of the wind farm, the DC/DC converters control the power flow in the wind farm and thereby also the voltage levels for the 1.5 kV DC link in the turbine as well as for the 32 kV DC collection bus. For the limited bandwidth resulting from the switching frequency 1 kHz and the maximum voltage deviations of 5 % for the DC voltages, the required capacitances are 152 mF for the DC link in the wind turbine and 16 mF for the DC bus, both giving a stored energy corresponding to 74 ms transferred rated power. In the case of a fault in the connecting main grid, the output power from the wind farm must be decreased. Here, assuming that the excess power is dissipated in each turbine, the detection of the fault as well as the disconnection and the reconnection of the wind farm are investigated. The requirements for the HVDC link to avoid over voltages during a grid fault are stated and it is also shown that the reconnection can be done within 14 ms, which is well within the time specified in existing grid codes. Further, the behavior of the system during internal faults for the DC bus is investigated. Methods for detecting and finding the location of the faults are determined, and it is shown that a faulted part can be disconnected and the non-faulted parts reconnected within 300 ms without using fully rated DC breakers.
Chat Functionality for Communication between Centralized Control Room and Field Operators in a Nuclear Power Plant

The Nuclear Power Industry nowadays is still operating with communication equipment that does not utilize the technology that has become common the last 20 years. There is a desire to upgrade these communication systems, and a research activity has been started on this task at the OECD Halden Reactor Project. As the communication between field operators and control room still consist of a broadcast/landlines-system a possibility is to add a portable unit with a synchronous messaging feature, commonly known as a chat. As the consequences of faults in a Nuclear Power Plant is potentially fatal, one of the main considerations, in addition to improving efficiency, is to maintain security. To do so the communication between the control room and field operators need to contain, ideally, no mistakes or confusion. The efficiency is believed to be improved by making it possible for the operators to stay put, answering certain questions from the control room in writing. To achieve a low rate of misunderstandings and confusion some extra features is added to the application, tested by writers of other articles about chat confusion. When interviewing operators abut the application there is a bit of scepticism about the need for such an extension. An optimism about communication with multimedia is showed and this is a feature that the operators them selves believe to be useful. The system made in this article is made as an input to the portable device application to be tested during 2014, and need extensive testing. In order of achieving the goal of no misunderstandings or confusion the application needs to be tested mainly on the amount of use, amount of misunderstandings and how the operators perceive its user friendliness compared to traditional systems.
Network Science: Observations from the Omni Fusion 2007 Digital Warfighter Exercise Simulation Experiment

Abstract : Net-centric operations depend on the development of coherent systems of interacting networks using rapidly evolving information technologies, doctrine, and training paradigms (National Research Council, 2005). To this end, research and experimentation are required to understand the organizational processes and procedures required to enable network command and control (C2). This paper details the application of network science to understand human network interactions in a recent command and control simulation experiment, the Omni Fusion 2007 Experiment/Digital Warfighting Exercise Block III simulation exercise (SIMEX). This paper describes research and analyses about the promulgation of situation awareness (SA) and understanding throughout a Division and subordinate Brigade organizations. Social network analysis (SNA) was used to help determine the structure of human relations and to express that structure in network form. The SA data collected and the results from the SNA, taken together, assisted in understanding organizational networks, networking technology capabilities, and intra-and inter-team processes facilitating the development of SA among distributed and collocated commanders and staff within the refined modular division.
Birch regeneration: a stochastic model

The regeneration of a clearcutting with paper or yellow birch is expressed as an elementary stochastic (probabalistic) model that is computationally similar to an absorbing Markov chain. In the general case, the model contains 29 states beginning with the development of a flower (ament) and terminating with the abortion of a flower or seed, or the development of an acceptable stem, unacceptable stem, dead seedling, or nongerminate (the six absorbing states). Expressions are given for the expected mean number of occurrences of each state, and the probability of arriving at any absorbing state after the occurrence of any transient state.
Application of architectural patterns and lightweight formal method for the validation and verification of safety critical systems

Abstract : This thesis researches the role of software architectural patterns and lightweight formal methods in safety-critical software development. We present a framework that relates the different activities and products from system engineering, safety engineering, system and software requirements, and software architecture explicitly, and demonstrate the proposed framework with a case study involving the architectural design of the software to control the arming device of a fictitious Surface-to-Air Missile. We describe the safety engineering steps for the identification of the system hazards and the critical functions that the software has to provide to avoid premature detonation, resulting in four safety requirements for the software that controls the missile's Electronic Safe Arm Device (ESAD). We formalize the software safety requirements as statechart assertions and validate their correctness via JUnit test. We develop a software architecture for the control software using the Safety Executive pattern, and implement the design in C++ to support a simple time-step simulation to produce the required log files for the automated verification of the design.
Supervisory Control Information Management Research (SCIMR) Studies: Determination of Efficiency for a Variety of Input Control Equipment (DEVICE)

Abstract : This study investigated the effectiveness of several commercial, off-the-shelf input devices as alternatives to the standard mouse for simple computer screen movements and interactions. The devices were the standard mouse, the Belkin n52te, the Saitek Cyborg Command Unit, the Wacom Bamboo Fun with stylus, the Wacom Bamboo Fun with touch, and the Xbox 360 controller. Participants performed repetitions of 4 tasks with each device: neutral point movement, dragging, tracking, and zooming. Sixteen of the 20 comparisons between the standard mouse and the other five devices were statistically significant. In all instances where the difference was statistically significant, the standard mouse outperformed the other devices.
Physiological Responses to Wearing the Helicopter Aircrew Integrated Life Support System (HAILSS) in Hot Environments

Abstract : Individuals wearing encapsulating garments require auxiliary cooling systems to sustain physical and cognitive performance when exposed to high temperatures or workloads. The Helicopter Aircrew Integrated Life Support System (HAILS S) is designed to minimize thermal problems by incorporating normal flight suit functions with protective functions (fire, chemical and biological warfare (CBW), and cold water immersion) in a single, integrated clothing ensemble. This study evaluated the effectiveness of the HAILSS cooling concept by comparing heat loads incurred while performing up to 6 hi of physical work in either HAILSS or the current A/P22P-9(V) CBW protective ensemble. This study exposed seven test subjects (six male, one female) to six experimental trials each. Subjects wore the HAILSS (h20, h75) and CB (m20, HAILSS% N" 75" 35" a) Need for head ventilation b) Airflow though breathing valve adequate but saliva a problem, "mouth too were M.L. nt moderate physical work (40% of an individual's maximum oxygen uptake) and cognitive tasks. In addition, each subject had one exposure using HA%S without the chemical protective AR-5 hood (h75n) and another employing HAILSS with cooled ventilation air (24C inlet air temperature) (h75c) in the hot/humid condition. Test results indicated 20% RH trials lasted significantly longer (p<O.Ol) and were significantly less stressful (p<O.O5) than 75% RH trials based on various physiological parameters. Increasing heat removal by ancillary cooling brought the level of heat strain experienced in the HAILSS assemble at 75% RH to roughly that of Mk 1 or HAILSS at 20% RH. HAILSS or Mk I without ancillary cooling was demonstrably more stressful to wear at 75% RH than at 20% RH. Operational mission performance would likely degrade at this higher RH without active cooling. These results demonstrate that ambient relative humidity significantly affects heat removal even in totally encapsulated protective clothing ensembles.

Technology, performance and team adaptation to regulation in Formula 1

This paper looks at how competition, regulation and technology coevolve in Formula 1 and how teams adapt. It does so at two levels: (i) the system level viewing Formula 1 competition as a whole and (ii) the organizational level, viewing team adaptation and car development level. The path this coevolutionary trajectory competition has taken in modern Formula 1 (1970 – 2013), is examined by looking at season results and regulation changes that punctuate its path. The understanding developed through this are summarised in a causal loop diagram and some implications are worked out for the forthcoming 2014 season.
Unifying framework for control system design under uncertainty and its implications for chemical process control

Model uncertainty is one of the major problems facing control system designers in practice. In this paper a general approach is outlined for the assessment of the effects of model uncertainty on control system performance. Also discussed are methods for the design of controllers which meet given performance specifications despite model uncertainty. The power of the new techniques as well as the failure of the traditional ones is illustrated on two examples widely studied in the process control literature. The design of Smith Predictor controllers and the design of 2-point composition controllers for high purity distillation columns.
One-year stability of physical education-centered physical literacy indicators on objectively measured physical activity

One of the central goals of school physical education (PE) is to improve physical literacy in youth to nurture their ability, confidence, and desire to be physically active for life. The aim of this study was to examine the stability of the selected PE-centered physical literacy indicators on school students’ objectively measured moderate-to-vigorous intensity physical activity (MVPA). This study was a follow-up study tracking a sample of 450 Finnish children (M = 11.26[0.32]; nfemales = 194; nmales = 256) across upper elementary school from fifth (T1) to sixth (T2) grade. A set of independent variables (motor competence, health-related fitness, in-class PE MVPA, and PE motivation and enjoyment) and total MVPA as a dependent variable were collected, and gender and body mass index were controlled in the analyses. The entire model explained almost 29% of MVPA in T1 and 26% in T2. While cardiorespiratory endurance (β = 0.29) and MVPA in PE (β = 0.20) were statistically significant predictors of MVPA in T1, MVPA in PE (β = 0.23), and identified regulation (β = 0.16) were statistically significant predictors at T2. Across the time, boys had higher levels of MVPA compared to girls (T1: β = −0.12; T2: β = −0.14), whereas the relationship was inverted in motor coordination (T1: β = 0.13; T2: β = 0.12). The findings of this study suggest that MVPA in PE is an important contributor to children's MVPA, and its role is eminent during the last two grades of elementary school.
Use of miR-34a, miR-126, and miR-125a-5p expression level as diagnostic factor and therapeutic target for α-L-guluronic acid and β-D-mannuronic acid in Type-I diabetic rat models

Type 2 diabetes mellitus (T2DM) affects microRNAs (miRNAs) expression that are known as Post-transcriptional repressors of gene expression in plants and animals. This research aimed to investigate the expression levels of miR-34a, miR-126, miR-125a-5p, and miR-29b for diabetes diagnosis, and the effect of α-L-guluronic acid and β-D-mannuronic acid supplementation on the expression pattern of these miRNAs in diabetic rats. Total miRNAs were extracted and evaluated by qRT-PCR method. body weight, fasting insulin levels, food intake and Vitamin D level in four group after 4-week intervention also measured. The analyzes showed significant increase in expression levels of miR-126 and miR-125a-5p, in diabetic control groups (p=0.001). Also, miR-29b was undetectable in the sera of experimental rats. After treatment with β-D-mannuronic acid, the expression level of miR-34a was upregulated in diabetic rats (p=0.026), but α-L-guluronic acid was not significantly effective. Also, expression levels of miR-126 (p=0.026) and miR-125a-5p (p=0.041) were downregulated significantly in diabetic rats, after treatment with β-D-mannuronic acid and, α-L-guluronic acid respectively. these results suggest that use of miR 126 ,125a-5p and miR 34a for diagnosing diabetes is sensible, also we can consider β-D-mannuronic acid as new therapeutic agent for correct disturbance in miRNA profile of diabetic rats.
