Ground reaction force characteristics of Tai Chi push hand

Push Hand is an advanced training technique for the Yang-style old frame 108 forms Tai Chi Chuan. It is performed by two practitioners. To clarify how people use forces during Push Hand training, it is important to review the ground reaction force (GRF). Here, we quantify the characteristics of the GRF during Push Hand training. Kinematic data and GRF data from 10 Tai Chi Chuan practitioners (29.9 ± 7.87 years) were synchronously recorded using a three-dimensional motion analysis system (200 frames · s−1) and three-dimensional force plates (1000 Hz). The resultant GRF for both feet for the 0%, 50% and 100% phases of attack and defence were compared to body weight using a paired-samples t-test. The differences in the resultant GRF between the 0%, 50% and 100% phases of attack and defence were tested by one-way repeated-measures ANOVA. The significance level was set to 0.05. The total resultant GRF was almost equal to the participant’s body weight in push hand. This result was consistent throughout the entire push hand process. Our results revealed that the GRF was comparable to the body weight, implying that practitioners do not push or resist their opponents during the push hand process.

Preliminary investigations of HE performance characterization using SWIFT

Preliminary experiments are performed to assess the utility of using the shock wave image framing technique (SWIFT) to characterize high explosive (HE) performance on detonator length and time scales. Columns of XTX 8004, an extrudable RDX-based high explosive, are cured directly within polymethylmethacrylate (PMMA) dynamic witness plates, and SWIFT is employed to directly visualize shock waves driven into PMMA through detonation interaction. Current experiments investigate two-dimensional, axisymmetric test geometries that resemble historic aquarium tests, but on millimeter length scales, and the SWIFT system records 16-frame, time-resolved image sequences at 190 ns inter-framing. Detonation wave velocities are accurately calculated from the time-resolved images, and standard aquarium-test analysis is evaluated to investigate calculated shock pressures at the HE/PMMA interface. Experimental SWIFT results are discussed where the charge diameter of XTX 8004 is varied from 2.0 mm to 6.5 mm.

비정렬격자를 이용한 프로펠러 성능 및 주위 유동해석

A CFD(Computational Fluid Dynamics) analysis is presented to predict hydrodynamic characteristics of a marine propeller. A commercial RANS(Reynolds Averaged Navier-Stokes equation) solver, namely FLUENT, is utilized in conjunction with fully unstructured meshes around rotating propeller. Mesh generation process is greatly accelerated by using fully unstructured meshes composed of both isotropic and anisotropic tetrahedral elements. The anisotropic tetrahedral elements were used in the flow domain near the blade and shaft, where the viscous effect is important, having complex shape yet resolving the thin boundary layers. For other regions, isotropic tetrahedral elements are utilized. Two different approaches simulating rotational effect of the propeller are employed, namely Moving reference frame technique for steady simulation, and Sliding mesh technique for unsteady simulation. Both approaches are applied to the propeller open water (POW) test simulation. The current results, which are thrust and torque coefficients, are compared with available experimental data.

A Threatening Space?: Stigmatization and the Framing of Autism in the News

The public develops interpretations of physical and mental disabilities through a variety of resources, most notably representations presented by the news media. While disability scholars have long lamented negative portrayals of disabilities in the mass media (e.g., movies, fictional television programs, songs) as dehumanizing and devaluing, studies of news media depictions have been scant. The present study focuses on a salient mental disability—autism—to advance current scholarship about representations of disabilities in the news. Stigmatizing cues and framing techniques from news coverage of autism over a period of approximately 15 years suggest that journalists may be creating a threatening space for autism, particularly through the perpetuation of stigmatic cues in more than two-thirds of news coverage of autism, coupled with the selection of certain news frames. Implications for media and disabilities practice and scholarship are discussed.

Mechanisms of Psychological Distress following War in the Former Yugoslavia: The Role of Interpersonal Sensitivity

While high prevalence rates of psychological symptoms have been documented in civilian survivors of war, little is known about the mechanisms by which trauma exposure might lead to poor psychological outcomes in these populations. One potential mechanism that may underpin the association between war-related traumatic experiences and psychopathology is interpersonal sensitivity. In the current study, we applied structural equation modeling to investigate the impact of interpersonal sensitivity on posttraumatic stress disorder (PTSD) symptoms, depression symptoms, and anger responses following exposure to war trauma. 3313 survivors of the war in the former Yugoslavia were identified and selected using a multistage, probabilistic sampling frame and random walk technique. Participants were interviewed regarding trauma exposure, interpersonal sensitivity, and PTSD symptoms, depression symptoms, and anger responses. Structural equation modeling analyses revealed that the relationship between trauma and PTSD symptoms and depression symptoms was partly statistically mediated by interpersonal sensitivity. Further, findings indicated that the relationship between trauma and anger responses was fully statistically mediated by interpersonal sensitivity. These results suggest that interpersonal sensitivity may function as a key mechanism that contributes to psychopathology following trauma.

Enhanced PLL based SRF control method for UPQC with fault protection under unbalanced load conditions

This paper presents novel control strategy of a three-phase four-wire unified power quality conditioner (UPQC). It is used to improve power quality in distribution system. The UPQC is realized by the integration of series and parallel active power filter (SAPF and PAPF) sharing a common dc bus capacitor. The realization of parallel APF and series APF are carried out using a three-phase, three legs voltage source inverter (VSI) with split capacitor. In both APFs the fundamental source voltages and currents are extracted by synchronous reference frame technique. SAPF connected with the supply by series transformer. The secondary of series transformer is affected by load side short circuits. This paper also explains the control circuit for protection of series transformer against over voltage and over current. PAPF connected with the system by series inductance. The performance of the applied control algorithm of shunt active filter with series active filter is evaluated in terms of power-factor correction, load balancing, and mitigation of voltage and current harmonics in a three-phase four-wire distribution system for non-linear load, unbalanced supply and load conditions . Sinusoidal PWM current controller, modulated hysteresis current controller are used for generation of switching pulses to series and parallel APFs. The two control algorithm is simulated by use of MATLAB/Simulink-based environment and the obtained results validated through experimental study with the UPQC hardware prototype.

A study into how high school students learn using narrative frames

In order to explore student learning experiences in English language classes, this study employed a qualitative data collection method known as narrative frames, which uses prompts to stimulate written expression of ideas. Data were collected through narrative frames on three different occasions from 36 second-year high school students in a team-taught EFL classroom in Japan, in both English and Japanese. After collecting the frames, individual interviews were conducted with two students from the class and their team teachers to further enquire about their experience, particularly with regard to the use of narrative frames. Findings suggest that the narrative frame technique proved to be a beneficial tool for improving learner autonomy. It facilitated the students becoming responsible for their learning in general, and encouraged them to become more serious about their learning of the English language. Methodological implications for the future use of narrative frames are provided.

ANLAM ANALİZ METHODUNUN TENNESSEE GAZETESİ OLAN ŞEHİR GAZETESİ'NE UYGULANMASI: NASHVİLLE, TENNESSEE'DE KÜRT GURUR ÇETESİ KÜLTÜRÜNÜN ANLAŞILMASI

The purpose of this paper is to examine how the Tennessean newspaper The City Paper and its readers’ comments frame the coverage of the Kurdish Pride Gang. This study observes how news coverage regarding the Kurdish Pride Gang (KPG) influences reader’s opinions in Nashville, Tennessee. This research focuses on how readers vary in their interpretation of news coverage of the KPG in the newspaper. A single article can generate many unique interpretations. This research does not suggest that the news coverage directly causes racist attitudes. Conversely, this study examines the trigger effects of news coverage, including the construction of readers’ interpretation of the news. Moreover, this study tests how news coverage about the Kurdish Pride Gang is constructed in media coverage. In this regard, the theory symbolic interactionism is applied to study interpretation of media coverage among the individuals. Content analysis technique is employed to analyze data and in addition, coding and frame techniques are also used to observe the data.

The Population-Based Optimization Algorithms for Role Modelling and Path Generation in Group Animation

Traditional animation by key frame techniques takes animators lots of time and vigour to model and simulate behaviours of crowds. For solving this problem, this paper presents a novel group animation generation approach based on population-based optimization algorithms. It is mainly divided into two parts. First, it puts forward a role modelling approach based on dynamic self-adaptive genetic algorithm and NURBS technology. Second, following the introduction to PSO (Particle Swarm Optimization) algorithm, a group path generative approach is presented. It simulates group behaviours, including cohesion and separation, dynamic object tracking and collision avoidance. Finally, a group of shark modelling and path generation images are exhibited as examples.

A FRAMING OF FUTURE EUROPEAN PARLIAMENT ELECTIONS 2014 IN A SOCIAL MEDIA CONTEXT

Communication in marketing has always been a continuous conceptual hybrid of input from various domains: marketing, P.R., communication, sociology. With the constant transformation of web 2.0. phenomenon, the demarcation lines between these domains and their influence has become more blured and difficult to pinpoint. As a result, specific research methods and theories have become adaptable instruments, laying the path for grounded theory approaches or new research methods. Framing theory, having as basis that the media focuses attention on certain events and then places them within a field of meaning, has shifted towards organisations, and further on, to institutions. Framing is a quality of communication that leads others to accept one meaning over another. Framing theory suggests that how something is presented (the “frame”) influences the choices people make. In online communicative contexts, their own personal framings allows the communicative actors to make use of language and forethought so that specific embodiments of future evolutions may be depicted. In our case, we shall focus on the topic: European Parliament elections, which are to take place in 2014, and on the manner in which it has been framed in two online chat session with three MEPs. It is our intention to identify the framing techniques used, the framing links and the framing alignments.

A unique method of retaining orbital prosthesis with attachment systems – A clinical report

Diminution of the orbital contents post-surgical removal of a malignant tumor can have a severe psychological impact on the patient in terms of function and esthetics. Therefore, esthetic remedy should be planned subsequently, since tumor obliteration precedes cosmetic concern. A convenient option for successful rehabilitation in such patients is a simple, user-friendly, removable orbital prosthesis. Retention of the prosthesis is one of the key factors for the successful rehabilitation. Spectacle frame, conformers, adhesives, osseointegrated implants, magnets or buttons have been used to impart retention to the prosthesis. The use of semi precision attachments in maxillofacial prostheses is limited to the osseointegrated prostheses. This case report describes a conventional spectacle frame technique, to retain the silicone orbital prosthesis using two different types of stud attachments viz., dalla bona and O-ring attachment systems.

Influence of drag and turbulence modelling on CFD predictions of solid liquid suspensions in stirred vessels

Suspensions of solid particles into liquids within industrial stirred tanks are frequently carried out at an impeller speed lower than the minimum required for complete suspension conditions. This choice allows power savings which usually overcome the drawback of a smaller particle-liquid interfacial area. Despite this attractive economical perspective, only limited attention has been paid so far to the modelling of the partial suspension regime.In the present work two different baffled tanks stirred by Rushton turbines were simulated by employing the Eulerian-Eulerian Multi Fluid Model (MFM) along with either the Sliding Grid algorithm (transient simulations) or the Multiple Reference Frame technique (steady state simulations). In particular, a comparison of alternative modelling approaches for inter-phase drag force and turbulence closure is presented. The results are evaluated against a number of experimental data concerning sediment features (amount and shape) and local axial profiles of solids concentration, with emphasis on the partial suspension regime.Results show that some of the approaches commonly adopted to account for dense particle effects or turbulent fluctuations of the volumetric fractions may actually lead to substantial discrepancies from the experimental data. Conversely simpler models which do not include such additional effects give the best overall predictions in the whole range of partial to complete suspension conditions.

Design and Analysis of a Submerged Membrane Reactor by CFD Simulation

AbstractCFD was applied to demonstrate the effect of reactor configurations on the fluid flow pattern in submerged membrane reactors. A mixture model, a realizable k‐ϵ model, and the multiple reference frame (MRF) technique were employed to simulate the solid‐liquid turbulent flow. Influences of the introduction of a ceramic membrane, the relative position between ceramic membrane and impeller, and the types of impeller on velocity profiles and concentration distributions were systematically discussed. These simulation results were validated qualitatively with experimental data for various reactor configurations.

Quantitative Analysis of Uranium Distribution in Plate Fuel Element Using Real Time Digital X-Ray Radiography

Dispersion type plate fuel elements were fabricated with U3Si2 dispersoids in aluminium matrix and clad in Al-alloy for the modified core of APSARA reactor by standard picture framing technique followed by hot roll bonding operation. In general around 85% reduction in thickness was carried out in fabricating the finished fuel plates. These fuel plates were then characterized by digital X-ray radiography technique to outline fuel meat boundary and also for the quantitative analysis of surface uranium metal density in the fuel meat. In order to evaluate the surface uranium density a non destructive technique was developed in which X-ray radiography image was digitized and gray value was calibrated in terms of uranium metal density. In addition, fuel meat and clad thickness of fuel plate was determined along longitudinal section by optical microscopy.

Youth Culture and Political Participation: The Case of Media Framing of Youth Protest at Ankara University in Turkey

In this study, I want to focus on the framing effect that the media has on public opinion. Political participation has become very popular in recent years. Youth participation, in particular, has gained importance because politicians pay more attention to the participation of the youth. Merely, the youth’s role is restricted to voting. Moreover, the media plays an important role in shaping the people’s attitude toward youth participation. I studied print media news reports on a student protest held at the Ankara University’s Faculty of Political Science on 8 December 2010 in Turkey. The students were protesting against a member of the Grand National Assembly of Turkey, Burhan Kuzu; some students even threw eggs at him. The press paid great attention to this event. For this purpose, I have employed the framing effect technique in concert with critical discourse analysis to analyse the two most popular Zaman and Hurriyet news reports in Turkey for a week in December 2010 in an attempt to understand the relationship between youth participation and the framing effect of the media. I wish to study the framing effect as a descriptive tool. In brief, these reports declared the protesters enemies of the public. This narrow view of participation is not suitable for a democratic improvement. DOI: 10.5901/mjss.2013.v4n3p339

Nonlinear Unbalanced Load Compensation for PV Sourced Grid Connected Inverter

The major problem in the PV system is the poor PV consumption under viable irradiation condition. So in order to improve the power consumption of PV along with grid connected inverter, this system has been implemented with controller analysis and model. This system is mainly used for non linear load compensation under unbalanced condition. In the existing method, Peak current of the inverter is reduced during the unbalanced grid-voltage sags with the help of current harmonics injection which increases the total harmonic distortion. Double synchronous reference frame technique with PLL is used to synchronize PV with grid. As well as the maximum power point of PV is tracked using Incremental Conductance technique to reduce the error and improves the system efficiency. Selected simulation results using MATLAB/Simulink are reported in order to show the proposed system efficient.

Framing quality improvement tools and techniques in healthcare

The purpose of this paper is to present a study of how quality improvement tools and techniques are framed within healthcare settings. The paper employs an interpretive approach to understand how quality improvement tools and techniques are mobilised and legitimated. It does so using a case study of the NHS Modernisation Agency Improvement Leaders' Guides in England. Improvement Leaders' Guides were framed within a service improvement approach encouraging the use of quality improvement tools and techniques within healthcare settings. Their use formed part of enacting tools and techniques across different contexts. Whilst this enactment was believed to support the mobilisation of tools and techniques, the experience also illustrated the challenges in distributing such approaches. The paper provides an important contribution in furthering our understanding of framing the "social act" of quality improvement. Given the ongoing emphasis on quality improvement in health systems and the persistent challenges involved, it also provides important information for healthcare leaders globally in seeking to develop, implement or modify similar tools and distribute leadership within health and social care settings.

Adaptation as sadomasochism: The case of Guy Maddin’s Dracula: Pages from a Virgin’s Diary

Abstract The article argues that the violence of rhetoric pertaining to fidelity in adaptation – e.g., that the adaptation ‘destroys’ or ‘mutilates’ the adapted text – may at times be symptomatic not of displeasure, but of sadomasochistic pleasure in adaptation. As readers, viewers and listeners develop fantasmatic relationships to texts, they identify with narrative structures, characters and style. Reading, viewing or listening to an adaptation as such can thus be seen as a way of fantasizing both the adaptation and the adapted text, and particularly of fantasizing the latter’s wholeness of meaning and/or form. Guy Maddin’s exemplary Dracula: Pages from a Virgin’s Diary in 2002 is analysed in terms of its ‘dismemberment’ of the ballet on which it is based. While ballet is usually conceived as an art form that communicates through dancers’ whole bodies, Maddin’s film obscures parts of the frame through picture distortion and ‘cuts off’ parts of the bodies through framing and editing techniques in order to elicit sadomasochistic pleasure. The conception of a sadomasochistic form of adaptation is not, however, restricted to film adaptations of ballet, and the article briefly discusses other possible applications of the theory.

Assessment of decomposition rate of Acacia mangium litter for rehabilitating degraded mined sites

Acacia mangium, widely used to rehabilitate degraded mined sites, hasbeen reported to be slow in decomposition. The experiment was carried out to establish the rate of decomposition of Acacia mangiumleaf litter and determine the correlation between the stand age and decomposition rate ofits litter.Litter decomposition rate of Acacia mangium under monoculture plantation was studied using the wire mesh frame technique. Wire mesh frames containing 200g of fresh Acacia mangium leaves were set up in three Acacia mangiumstands of ages five, seven and nine years. Ten wire mesh frames were left in each stand using Completely RandomizedDesign.The decay rate coefficient “k” was used to determine the constant potential weight loss of the dry matter. The value of kwas estimated to be 0.0064, 0.0049 and 0.0039 for the 30 th , 60 th and 90 th days respectively, with overall mean of 0.0050 for all the stands. The Half-life estimated for all the stands was 140 days. Analysis of Variance at 5% significant level indicates significant difference between stand age in weight losses on the 30 th and 60 th daysbut no significant effect between the 60 th and 90 th days of observation; there were differences in the decomposition rate between the Acacia mangium leaf litter on the seven and nine years stands.
