Résumé :

A novel approach of task based conceptual design(TBCD) has been successfully used as direct guider and efficient developer of unique mechanical structures for many cases of mechanical design. Nearly a decade long efforts of elaboration of efficient every day usage formats for this method have been ended in convenient design pages suitable and applicable for revealing, describing, visualizing and managing the data necessary for organizing the design process from task definition to solutions satisfying original design tasks. The aim of current study is to show steps of a solution generation within frames of a single design cycle and extend this action over consecutive design cycles. Those steps are described from standpoint of general concept design method starting from key model and finished with final aggregation matrice as ultimate step of a single design cycle. Unified mathematical expressions are used for introduction and description of all worked out and developed components of conceptual design. The paper is arranged in a way to show gradual steps of conceptual design(CD) of a power transmission system – a pipe wrench life test machine.

Résumé :

With a communicative approach to language testing, performance assessment has taken on a prominent role in testing systems around the world. Specifically, task-based assessment (TBA) is now being used to make inferences about people’s language ability and what they can do with this construct under realistic communicative scenarios. This reflection paper discusses central issues in TBA, and in doing so, it shows that TBA can be observed through a classroom-assessment lens, an idea I present as Instructional Task-Based Assessment (ITBA). The paper starts by reviewing the meaning of tasks, then discusses problems with TBA and finally offers a checklist for teachers to explore TBA in classroom contexts. I also include limitations of the proposal and conclusions

Résumé :

It has been recognized by many researchers that the notion of test architecture should be utilized for software testing to cope with the task of testing complicated software, as it can support test architecture design and test case generation based on test architecture as well as efficient fault detection and error locating. However, in the current software testing theory and practice, the notion of test architecture and how it can be utilized for software testing are not well understood. To redress this situation, this paper provides foundational concepts and principles of architecture-based software testing to help utilize test architecture for software testing. Case study experiments are conducted to show how the concepts and principles of architecture-based software testing work and the effects that can be obtained by using architecture-based software testing.

Résumé :

Drawing on Glenn Fulcher’s extensive work in performance-based language assessment of speaking, this paper explores the assessment of L2 speaking ability in local language testing contexts. For that purpose, I review Fulcher’s influential work that highlights the relationship between the speaking construct, the task, the performance, and the scale, and I provide an overview of various task types, approaches to scale development, and rater-training programs. Then, I argue that local language testing provides a wide range of possibilities for task development, scale design, and rater training due to the opportunity for collaboration with local expertise (students, instructors, policy-makers) and the ability to keep up with the evolving speaking construct in the local context.

Résumé :

After a system failure that is attributed to human error, an accurate accounting of the factors that led to the error is critical for redesign efforts and any resulting litigation. Without data on the design components or environmental factors that contributed to the error, the human is indicted, either legally or in the press, no system redesign is conducted and the failure will be repeated at the cost of additional damage and/or lives. However, rarely is the human at fault because of intentional negligence. There are always design or environmental factors that interacted with the person's training, knowledge, motivation and other factors that can be affected by the system. Accident investigations must be conducted to identify these factors and guide redesign efforts. An even better situation would be if this same testing occurred before the system was released to the market. This requires prediction and simulation of the people who will use the system, the tasks that will be attempted, the motivations of system users, and the environmental factors that will interact with the system. Testing systems under controlled laboratory conditions is generally insufficient to identify potential sources of human error. This paper describes the critical components of task-based evaluation and presents a case study to illustrate the consequences of failure to use TBE.

Résumé :

The traditional CNN for 6D robot relocalization which outputs pose estimations does not interpret whether the model is making sensible predictions or just guessing at random. We found that convnet representations trained on classification problems generalize well to other tasks. Thus, we propose a multi-task CNN for robot relocalization, which can simultaneously perform pose regression and scene recognition. Scene recognition determines whether the input image belongs to the current scene in which the robot is located, not only reducing the error of relocalization but also making us understand with what confidence we can trust the prediction. Meanwhile, we found that when there is a large visual difference between testing images and training images, the pose precision becomes low. Based on this, we present the dual-level image-similarity strategy (DLISS), which consists of two levels: initial level and iteration-level. The initial level performs feature vector clustering in the training set and feature vector acquisition in testing images. The iteration level, namely, the PSO-based image-block selection algorithm, can select the testing images which are the most similar to training images based on the initial level, enabling us to gain higher pose accuracy in testing set. Our method considers both the accuracy and the robustness of relocalization, and it can operate indoors and outdoors in real time, taking at most 27 ms per frame to compute. Finally, we used the Microsoft 7Scenes dataset and the Cambridge Landmarks dataset to evaluate our method. It can obtain approximately 0.33 m and 7.51∘ accuracy on 7Scenes dataset, and get approximately 1.44 m and 4.83∘ accuracy on the Cambridge Landmarks dataset. Compared with PoseNet, our CNN reduced the average positional error by 25% and the average angular error by 27.79% on 7Scenes dataset, and reduced the average positional error by 40% and the average angular error by 28.55% on the Cambridge Landmarks dataset. We show that our multi-task CNN can localize from high-level features and is robust to images which are not in the current scene. Furthermore, we show that our multi-task CNN gets higher accuracy of relocalization by using testing images obtained by DLISS.

Résumé :

ABSTRACTTask-based language assessment (TBLA) has generated interest since the early 1990s, primarily in conjunction with the ongoing development of task-based language teaching (TBLT) and the pursuit of developing appropriate testing models for this approach to pedagogy (Norris, 2002, 2009). However, tasks also offer considerable advantages for language assessment, beyond their obvious relevance within TBLT classes and programs. In fact, major innovations in the general domain of language assessment over the past two decades have occurred in conjunction with the introduction of tasks into assessment design, largely in response to the need for tests that better represent examinees’ abilities to use the language (Mislevy, Steinberg, & Almond, 2002), but also because tasks offer a meaningful space for language teachers, testers, learners, and others to examine, understand, and improve language learning endeavors (Van Gorp & Deygers, 2013). This article reviews the considerable range of current uses for TBLA, illustrating different types of assessment with concrete examples and highlighting distinct roles for tasks as a basic unit of analysis in test design, interpretation, and intended consequence. Ultimately, it argues that tasks offer a fundamental, though not exclusive, foundation for useful language assessment, and that task-based assessment, though challenging, is probably worth the effort.

Résumé :

This study examines the interaction effect between rater groups and tasks on evaluating EFL learners’ written performances. Fifty raters took part in this study. The experienced rater group (n=25) and the novice rater group (n=25) judged sixty essays (30 narratives and 30 argumentative writing modes) written by third-year English students. Raters’ decision-making behaviours, in terms of scores assignment and written comments, were diagnosed based on different quantitative and qualitative tools. Scores were analysed based on FACETS to examine the effects of rater-task interaction on raters’ severity and internal consistency and the analytic scale’s functionality. Qualitative data were also analysed to diagnose which aspects of writing were deemed more important than others across rater groups and task types. The analysis revealed that both raters and tasks were substantially influential factors. The majority of expert raters displayed more severity in assessing narrative essays than argumentative essays. Different qualitative judgments are also detected across raters and tasks due to rating experience and task requirements. The findings of this study reflected implications not only for testing learners’ writing proficiency but also for test validation research in the task-based writing performance assessment field.

Résumé :

Most civil engineering structures have long service life and situate in severe environment. So it is the key to carry out testing task continuously according to scheduled demands for the long-term monitoring based on FBG sensing. But the existing instruments cannot satisfy the long-term and remote testing demands. Based on virtual instrument and remote panel technique, the automatic testing and controlling system for FBG sensor array were developed. Modularization programming method was adopted and the control program can be adjusted according to practical demands freely. The testing system can save and figure the results automatically, and it can also discern and process the error signal. These extend and perfect the function of traditional FBG demodulation instrument, and make the testing system more flexible and reliable. It greatly reduces the difficulties in remote and long-term testing task.

Résumé :

Parallel testing is the key to achieving parallel test task scheduling, and its core is allocating resources fairly and reasonably to the test tasks, then rearrange the execution order of the test tasks in meeting the priority relationship between the resource constraints and the conditions of the test tasks, making the whole test mission of this system can be completed in the shortest possible time and improving the test efficiency. The basic ant colony algorithm has been improved in this paper to fit the parallel test task scheduling and to obtain the task scheduling sequence that complete all testing tasks in shortest test time.

This paper has analyzed the entire testing task sets of the third-party software testing agencies. And for how to set these tasks to the process of projects’ research and development, proposed a new Software Process Model, which is an evolution of the helix structure. The model was based on the ideas of agile. It may become the first one that assigns the testing task sets to the whole process of software development in an independent third party perspective. The agile process model in this paper is major for the heavyweight projects’ research and development. Currently, this agile process model which is based on the independent third party has been adopted in practice projects, and achieved good results.

Résumé :

Cloud computing has become ubiquitous in the enterprise environment as its on-demand model realizes technical and economic benefits for users. Cloud users demand a level of reliability, availability, and quality of service. Improvements to reliability generally come at the cost of additional replication. Existing approaches have focused on the replication of virtual environments as a method of improving the reliability of cloud services. As cloud systems move towards microservices-based architectures, a more granular approach to replication is now possible. In this paper, we propose a cloud orchestration approach that balances the potential cost of failure with the spot market running cost, optimizing the resource usage of the cloud system. We present the results of empirical testing we carried out using a simulator to compare the outcome of our proposed approach to a control algorithm based on a static reliability requirement. Our empirical testing showed an improvement of between 37% and 72% in total cost over the control, depending on the specific characteristics of the cloud models tested. We thus propose that in clouds where the cost of failure can be reasonably approximated, our approach may be used to optimize the cloud redundancy configuration to achieve a lower total cost.

Résumé :

Two national commissions have encouraged the development of a mileage-based charging system as a future alternative to the fuel tax. A 2012 Government Accountability Office report recommends a federal pilot program for evaluating mileage-based user fees. The state of Oregon has taken the lead in testing and moving toward a limited application of mileage-based user fees, and several states have initiated demonstrations, surveys, and policy studies. The findings and recommendations are presented from a 2011 policy task force study in Minnesota, and the lessons learned from this effort are discussed. The task force concluded that fairness was a primary reason for considering a mileage-based user fee system; the system is not just a means of raising revenue to fund future transportation infrastructure. As vehicles become more fuel efficient, some vehicle users are paying less per mile through the gas tax for transportation services than are others, and some are paying nothing at all if they drive electric vehicles.

Résumé :

The DMDX software package (Forster & Forster, 2003) is a Windows-based application that displays stimuli and records responses. Recent developments in this program have made it possible to deploy DMDX experiments over the Internet. This study evaluates the viability of the web-deployable implementation of DMDX, or webDMDX, for masked priming experiments. A lexical decision task (LDT) with masked repetition priming on high- and low-frequency words and an e/a letter detection task were conducted with both lab-based DMDX (labDMDX; Experiment 1) and webDMDX. The webDMDX experiments were run on lab computers (Experiments 2) and on different (unknown) hardware (Experiment 3). The labDMDX and webDMDX experiments yielded comparable results on the LDT. In the e/a-detection task, the only important difference observed among the tests was between the lab-based experiment (Experiment 1) and the first webDMDX experiment (Experiment 2), at the 50 ms display duration. However, after a minor change in keyword coding (Experiment 2 follow-up) and an adjustment to the millisecond-to-retrace conversion process (Experiment 3), the detection rates at all display durations were similar in both labDMDX and webDMDX. Taken together, these results indicate the utility of webDMDX for masked priming experiments as well as for other time-sensitive methodologies.

Résumé :

Trust is a key feature of social relationships. Common measures of trust, questionnaires and economic games, lack ecological validity. Hence, we sought to introduce an immersive, virtual reality (VR) measure for the behavioral assessment of trust across remote and in-person settings, building on the maze task of Hale et al. (2018). Our ‘Wayfinding Task’ consists of an interconnected urban environment for participants to navigate on the advice of two characters of differing trustworthiness. We present four studies implementing the Wayfinding Task in remote and in-person testing environments and comparing performance across head-mounted display (HMD)-based VR and desktop setups. In each study, the trustworthiness of two virtual characters was manipulated, through either a fact sheet providing trustworthiness information, or a behavior-based trustworthiness manipulation task termed the Door Game, based on Van der Biest et al., 2020. Participants then completed the Wayfinding Task. Overall, we found that participant behavior in the Wayfinding Task reflected the relative trustworthiness of the two characters; in particular, the trustworthy character was approached more often for advice, reflecting data from our Door Game. We found mostly null results for our novel outcome measure, interpersonal distance. Remote testing successfully achieved these effects. While HMD-based VR and desktop setups both showed these effects, there was a stronger effect of trustworthiness in the HMD VR version of the task. These results have implications for the measurement of trust in behavioral settings and the use of remote and VR-based testing in social experiments.

Résumé :

Computer-assisted language learning knowledge tests should no longer be designed on traditional skills to measure individual competence through traditional skills such as reading, comprehension and writing, but instead, it should diagnose interactive and communication skills in foreign lan-guages. In recent years in online education, it has been necessary to review the concept of interactive competence in digital environments in a comple-mentary way to its traditional use. It is important to promote a new typolo-gy of alternative tasks and items in tests where examinees can prove a real interactive performance in communication and interaction through the digi-tal scenario. This should be done through tools that facilitate oral negotia-tion, the management and understanding of the information extracted from online repositories, the search for suitable online digital material, and the use of new modes of audio-visual communication. Although some of these tasks have been used in a complementary way in the design of language tests previously: it is true that they have not been applied in a coherent way to be used as an assessment tool. A first approach was made by Miguel Ál-varez, García Laborda & Magal-Royo (2021) in the development of oral ne-gotiation skills through the use of interactive tools. The current online as-sessment models analyzed by García Laborda & Álvarez Fernández (2021) indicate the need to seek new ways of assessing foreign languages through the design of tests that fit in the current digital and interactive world.

Résumé :

Testing is an effective approach for finding discrepancies between intended and actual system behavior. However, the complexity of modern system can make it difficult for analysts to anticipate all the interactions that need to be tested. This is particularly true for human-interactive systems where humans may do things that were not anticipated by analysts. We address this by introducing a novel approach to automated test case generation for human-machine interaction. We do this by combining formal models of human-machine interfaces with formal models of human task behavior. We then use the robust search capabilities of model checking to generate test sequences guaranteed to satisfy test coverage criteria. We demonstrate the capabilities of our approach with of a pod-based coffee machine. Results and future research are discussed.

Résumé :

Abstract One of the causes of the annual decline in the forest area in Indonesia is forest and land fires. To prevent forest and land fires, the government carries out integrated patrol activities by forming a team for fire-prone area. A mobile application called Patroli Karhutla has been developed to facilitate the data recording obtained by the integrated patrol team. This study aims to produce recommendations for improvement in terms of usability based on evaluation and testing by users of the application in Sumatra. Evaluation and improvement of the application were conducted before testing. Testing includes two components, namely task success and efficiency, using several methods such as observation, interviews, focus group discussions, and concurrent think aloud. The test results on task success based on the level of success showed that the average task success of Patroli Karhutla application reached the target except for the profile and observation report. The average task success in scenarios done by respondents is 83.9 based on the indicators. The geometric mean-time of work on the scenario of the respondents has not reached the target and got two times the specified benchmark time. Errors and comments provided during testing by respondents produce some recommendations for improvement in the application for further development.

Résumé :

Teachers play the most important part in the application of a new method or approach in English language education. However, whether they implement the method successfully or not depends on various factors. This paper aims to explore the factors that affect English as a foreign language (EFL) teachers’ implementation of task-based language teaching (TBLT) at the tertiary level through the use of two instruments: “focus-groups” with five experienced EFL teachers and interviews with ten individual teachers at five universities in Ho Chi Minh City, Vietnam. The findings revealed that factors affecting teachers’ implementation of TBLT include external factors such as time allocation, testing, students’ motivation and English proficiency and textbooks, and internal factors such as teachers’ experience, knowledge about TBLT, English proficiency, and ability to use technology. The findings of the study provide EFL curriculum designers and teachers with both theoretical and practical implications in the implementation of TBLT at the tertiary level in Vietnam.

Résumé :

Planning of pilot testing is among important problems of creation of Enterprise resource planning. Pilot (experimental) projects are intended for testing of the main functions of the created system by limited number of “advanced” users. A key task when planning pilot testing is determination of its volume. If the volume of the pilot project is small, then essentially important functions of system can be not checked, and the probability of detection of essential mistakes at full introduction will be high. If the volume is big, then amount of works on implementation of the pilot project considerably increases, and there will be no necessary speed and flexibility of testing of the main functions, because of which pilot testing is organized, and its efficiency will be close to efficiency of full introduction. The article describes mathematical problem definition of pilot testing scoping which relies on results of the solution of formation problems of a portfolio of IT services and creation scheduling of Enterprise resource planning of the large metallurgical company. The solutions for the considered task are sets of the services and communications which are subject to check between them satisfying to the set restriction for volume of the resources allocated for testing realization, and delivering an optimum to the set criterion. The procedure of the task solution is based on network programming method which relies on structural and similar network representation of criterion and restrictions. The procedure and an example of the solution of the studied task in which separate estimated tasks are solved by method of dichotomizing programming are shown. The received approximate solutions of an objective can be improved by means of the solution of a dual problem of network programming. For the purpose of finding of initial task global optimum, the method of branches and borders can be used in which the criterions of function of the found approximate solutions are applied as border values. The considered task can be generalized for preferences of the consumers of IT service concerning need of check of services various communications. These preferences can be considered by introduction of “scales” of the corresponding communications. The general scheme of the solution of a task at the same time doesn’t change.

Résumé :

Road tracking, traffic sign recognition, obstacle avoidance, and real-time acceleration and deceleration are some critical sub-tasks in autonomous driving. This research proposed to use a single-sensor (camera) based intelligent driving platform to achieve multi-task (four subtasks) autonomous driving. We adjusted the function combinations and hyperparameters of the model to improve the model training and model testing performance. The experiments showed that the existing function combinations could not significantly improve the autonomous driving performance, and the loss function had a significant impact on the autonomous driving performance of the model. Therefore, we designed a novel loss function (MFPE) based on multi-task autonomous driving. The models with the MFPE loss function outperformed the original and existing models in model training and actual multi-task autonomous driving performance. Meanwhile, the model with the MFPE loss function achieved multi-task autonomous driving under different lighting conditions, untrained routes, and different static obstacles, which indicates that the MFPE loss function enhances the robustness of the model. In addition, the speed of the intelligent driving platform can reach up to 5.4 Km/h.

Résumé :

Many older adults living with heart failure struggle to follow recommended self-management routines. To help older adults with heart failure more effectively and efficiently self-manage their disease, we developed Engage, a mobile health application promoting the performance, logging, and sharing of routine self-management behaviors. This paper reports on the usability evaluation of the Engage system with 15 older adults with heart failure and informal caregivers. In two phases, participants used Engage during a task-based usability test (n=5) and a scenario-based usability test (n=10). Usability and performance data were assessed through video-recorded observation and the administration of the system usability scale (SUS) and NASA Task Load Index (TLX). We found that task-based testing was useful in quickly identifying problems within our application, but scenario-based testing elicited more valuable feedback from older adults. A comparison of the different evaluation methods used and the discussion of the challenges encountered provide multiple implications for the practice of usability testing of mobile health products with older adults.

Résumé :

The purpose of this project was to adapt an existing computer-based task called Multi-Attribute Task Battery (MATB-II), developed by NASA and frequently used to induce acute stress among air craft crew members and general populations, for use in medical populations. We gathered continuous electrocardiography (ECG) data while medical students completed four different versions of the MATB-II of varying difficulties alongside questions probing medical knowledge, comprising a new task called medically-focused multitasking game (MFMG). After completing each version, participants responded to questionnaires to assess subjective states of stress (State Trait Anxiety Inventory for Adults) and cognitive workload (NASA Task Load Index). Responses to these questionnaires, physiological data from continuous ECG, and overall performance scores were combined to determine one version of MFMG that represented the highest level of elicited stress, and one that represented the lowest level of elicited stress. The results of this pilot study are promising, and have converged to reveal one high-stress and one low-stress version of MFMG, which will later be used to induce acute stress in biofeedback intervention studies among surgical residents and fellows. Beyond this specific application, MFMG can have broader applications in measuring acute stress induction and/or reduction among populations of healthcare practitioners.

Résumé :

As the functions of mobile applications become more and more complex, the crowdsourcing testing puts higher demands on the professional skills of testers. Therefore, it is an important factor to ensure test quality how to effectively match test task requirements with test personnel's skill level and achieve accurate crowdsourcing test task recommendation. This paper proposes a crowdsourcing test task recommendation algorithm for mobile applications based on deep learning. Firstly, feature analysis is carried out for testing tasks and testers, and feature systems are designed respectively. Second, the resulting characteristic data is used as input data for the Stacked Marginalized Denoising Autoencoder (SMDA). The deep feature data learned from SMDA are combined as the input of Deep Neural Networks (DNN). Finally, the learning ability of DNN is used for prediction. Experimental results show that the proposed algorithm has obvious advantages in both performance and training time compared with CDL and AUTOSVD ++, which verifies the effectiveness of the proposed algorithm. The proposed algorithm can recommend testing tasks to appropriate testers and improve the precision of the algorithm.

Résumé :

The rapid development of applications has resulted in mobile application developers competing to create applications that are useful for the wider community, as is the case with the Zenly application. Through this application, every user can easily meet in real life, track the current whereabouts of someone with their consent, find the whereabouts of friends or relatives who are lost in the crowd, and follow the progress of the closest people. This research aims to determine the level of usability of the Zenly application and provide suggestions for improvement. The research stages followed a sequence of methods, including usability testing, preparation, execution, and analysis, time efficiency, and SEQ (Single Ease Question). Data was obtained on the average task time, success level, completion rate, and the lowest time efficiency, with task 1 taking 14,357 seconds, 38% success rate, two partial completions, and 87.5% completion rate. Based on the testing of these aspects and the results of the SUS (System Usability Testing) value of 71 Grade C (Good), the level of usability of the Zenly application is quite good but improvements need to be made, especially for task 1.

For inspection of steam generator tubes in nuclear power plants using eddy current testing, it is a very crucial task to extract the flaw signal from signals compounded by flaws and supporting structures. To perform such an important task, the multifrequency eddy current testing method is widely adopted. In this study, we explore the performance of a linear mixing technique based on the discrete cosine transform method by experiments. The results obtained using the DCT based method agree very well to those obtained by commercial software demonstrating the effectiveness of the approach.

Résumé :

Abstract This study experimentally evaluated Polish school students’ competence at written communication, understood as one of the forms of social communication. The task, performed online, was designed to see if the students were able to select the most important information from a given base text and to compose new texts on this basis to comply with three different length requirements, and how they behaved under the pressure of the time allocated to complete the sub-tasks. Results from an overall pool of 500 secondary school students from a diverse sample of schools (in the city of Poznań and the surrounding Wielkopolska province) that differed in terms of type and ranking suggest an overall poor competence at various composite skills involved in written social communication: information selection, summarization, logical structuring, and cohesive embellishment. Participants clearly exhibited various problems with concisely formulating thoughts, properly complying with instructions, etc. Composing a short, written message (based on a provided base text) and/or freely embellishing and reformulating information clearly caused them considerable difficulty. The article closes with some suggestions for how the methods used could potentially be improved in future studies of this type.

Résumé :

Language Teaching Media is one of the obligatory courses for the fifth semester students in the English Language Education Study Program of Sanata Dharma University. It provides the students with theories on language teaching media and opportunities to create innovative teaching media. This study aims to develop a learning model for Language Teaching Media course. Therefore, this study uses Research and Development method proposed by Borg Galls. There are ten steps in the Research and Development method, namely: (1) Research and Information Collecting, (2) Planning, (3) Developing Preliminary Form of Product, (4) Preliminary Field Testing, (5) Main Product Revision, (6) Main Field Testing, (7) Operational Product Revision, (8) Operational Field Testing, (9) Final Product Revision and (10) Dissemination and Implementation. Since the aim of this study is to develop the learning model for Language Teaching Media Course, only three out of ten steps of the RD model were employed, namely: Research and Information Collecting, Planning, and Developing Preliminary Form of Product. The developed learning model would be useful to enable the students to develop and utilize media to facilitate language teaching using their creativity and innovation.DOI:doi.org/10.24071/llt.2018.210104

Résumé :

Various choline-based multi-ingredient supplementations (CMS) have been suggested in the current market, but the research is limited. The purpose of this study was to investigate the acute effect of a CMS on physical performance. Fourteen male college football players (20.4 ± 1.0 years) participated in a randomized double-blind crossover experiment separated by 7 days. Subjects were given a CMS or a placebo 60 min before physical performance testing measures, including maximum vertical jumps, maximum voluntary isometric contractions (MVIC), maximal voluntary concentric contractions (MVCC), and fatiguing contractions. Four MVICs and seven sets of two MVCCs at various loads (1 N·m to 60% MVIC torque) were performed with the knee extensor muscles while seated on a dynamometer before and after the fatiguing tasks. During the fatiguing tasks, 120 MVCCs (4 sets × 30 reps) were performed with a load equivalent to 20% MVIC. Twitch interpolation technique was used to assess muscle contractile properties and voluntary activation. No significant differences were seen at baseline between sessions for all testing measures including vertical jump height, strength, power, muscle contractile properties and voluntary activation. Rate of torque development and impulse was higher in supplemental session compared to control session throughout the fatiguing contractions (p = 0.018, p < 0.001, respectively). Acute CMS can improve explosive strength by delaying the onset of fatigue.

Résumé :

Transmission task static allocation (TTSA) is one of the most important issues in the automatic management of radio and television stations. Different transmission tasks are allocated to the most suitable transmission equipment to achieve the overall optimal transmission effect. This study proposes a TTSA mathematical model suitable for solving multiple intelligent algorithms, with the goal of achieving the highest comprehensive evaluation value, and conducts comparative testing of multiple intelligent algorithms. An improved crossover operator is proposed to solve the problem of chromosome conflicts. The operator is applied to improved genetic algorithm (IGA) and hybrid intelligent algorithms. A discrete particle swarm optimization (DPSO) algorithm is proposed, which redefines the particle position, particle movement direction, and particle movement speed for the problem itself. A particle movement update strategy based on a probability selection model is designed to ensure the search range of the DPSO, and random perturbation is designed to improve the diversity of the population. Based on simulation, comparative experiments were conducted on the proposed intelligent algorithms and the results of three aspects were compared: the success rate, convergence speed, and accuracy of the algorithm. The DPSO has the greatest advantage in solving TTSA.

Résumé :

This study has a purpose to find out the effectiveness of a task, which was exclusively invented for the study, on the students’ writing accuracy. The task, namely Language Output-based Task, is derived from the functions of the language output hypothesis proposed by (Swain, 1985). The three functions of language output are the noticing or triggering function, the hypothesis-testing function, and the metalinguistic or reflective function ((Swain, 1995);(Swain, M., and Lapkin, 1995). In her latest definition, Swain defines language output as an act of producing language either in form of speaking or writing (Swain, 1995). The study chose writing as the productive skill since the existing curriculum as this study conducted emphasized on accuracy in writing. In order to measure the students’ accuracy, the narrative text was involved in the study as it has a moderate level of language features. The samples of the study were the 60 first-year students of two different classes consisting of 30 students in each class. Since this is a pre-experimental study, it implemented pre test and post test to the experimental and control group. The pre and post test were created by involving the target text (i. e. narrative text). The result of the study showed that there was a significant difference between the post-test scores of the experimental group and the post-test scores of the control group. From its result, it was concluded that the Language Output-based task was effective to improve the students’ accuracy (Castro, C. and Wang, 2010; Izumi, 2002).

Résumé :

Adapting laboratory psycholinguistic methods to fieldwork contexts can be fraught with difficulties. However, successful implementation of such methods in the field enhances our ability to learn the true extent and limitations of human behavior. This paper reports two attempts to run word learning experiments with the small community of Nungon speakers in Towet village in the Saruwaged Mountains, Papua New Guinea. A first attempt involved running a cross-situational task in which word-object pairings were presented ambiguously in each trial, and an explicit word learning task in which pairings were presented explicitly, or unambiguously, in each trial. While this quickly garnered a respectable 34 participants over the course of a week, it yielded null results, with many participants appearing to show simple patterned responses at test. We interpreted the null result as possibly reflecting the unfamiliarity of both the task and the laptop-based presentation mode. In Experiment 2, we made several adjustments to the explicit word learning task in an attempt to provide clearer instructions, reduce cognitive load, and frame the study within a real-world context. During a second 11-day stay in the village, 34 participants completed this modified task and demonstrated clear evidence of word learning. With this success serving as a future guide for researchers, our experiences show that it may require multiple attempts, even by experienced fieldworkers familiar with the target community, to successfully adapt experiments to a field setting.

Abstract Despite the fact that translation teaching research has been gaining momentum over the last two decades, little has been written and therefore known about translation assessment in the teaching context. This article reports on a data-based empirical study of translation testing in China. The issues raised in it range from teachers’ attitudes towards testing to its objectives, design, contents, frequency, and its pedagogical roles. It is suggested that more research be done on translation testing, of which the first task is to develop a theoretical framework to provide guidance for translation testing practice and research. It is further recommended that translation testing be made more teaching-oriented and brought closer to the real world of professional translation.

Résumé :

Background: The application of continuum manipulators as assistive robots is discussed and tested through the use of Bendy ARM, a simple manually teleoperated tendon driven continuum manipulator prototype. Methods: Two rounds of user testing were performed to evaluate the potential of this arm to aid people living with disabilities in completing activities of daily living. Results: In the first round of user testing, 14 able-bodied subjects successfully completed the prescribed task (pick-and-place) using multiple control schemes after being given a brief introduction and one minute of practice with each scheme. In the second round of user testing, subjects ( n = 3 ) demonstrated between 29.5 and 48.9 percent improvement in completion time across twelve trials of a peg-in-hole task, and between 8.4 and 33.8 percent improvement across six trials of a task involving opening and closing a drawer. Conclusion: Based on these results, it is posited that continuum manipulators merit further consideration as a safer and more cost-effective alternative to existing commercially available assistive robotic manipulators.

Résumé :

According to modern standards of higher education (FSES 3++), teaching is aimed at developing a set of universal, general professional, and professional competencies in a graduate. In this regard, the problem of assessing the level of their formation arises. Since competence is a multidisciplinary concept, its assessment requires designing a task that simulates a real situation, which may require complex knowledge and skills related to different areas of knowledge. One of the modern tools for current and final control is computer testing. In this case, during one testing session, it is desirable to evaluate several competencies at once with a limited number of tasks. The task is relevant, because in the currently used classical one-dimensional one-, two- and three-parameter Rasch—Birnbaum models, it is assumed that all tasks in the test belong to the same area of knowledge.The purpose of the article is to propose a methodology for the intellectual assessment of several competencies based on the results of one testing session, based on the modification of the Bayes algorithm, in which the choice of the next task is carried out as a result of analyzing the entropy (uncertainty) of the subject’s attribution to typical combinations (patterns) of preparedness levels for different competencies.An original technique for regularizing the Bayes algorithm based on the assessment of the change in the entropy of the probability distribution over patterns and the Kullback—Leibler divergence has been developed, which makes it possible to identify the moment when the student gives an answer that does not correspond to what is expected from them, based on the analysis of previous answers. The proposed technique not only increases the stability of the Bayes algorithm for measuring the probability of a student belonging to a given pattern by slightly increasing the required number of tasks but also allows to model the actions of an examiner in the process of competencies assessment. In general, the developed approach makes it possible to objectively assess the levels of formation of several competencies based on the results of single test.

Texte intégral

Résumé :

Software testing is a very labor intensive and costly task. Therefore, many software testing techniques to automate the process of software testing have been reported in the literature. Assertion-Based automated software testing has been shown to be effective in detecting program faults as compared to traditional black-box and white-box software testing methods. However, the applicability of this approach in the presence of large numbers of assertions may be very costly. Therefore, software developers need assistance while making decision to apply Assertion-Based testing in order for them to get the benefits of this approach at an acceptable level of costs. In this paper, we present an Assertion-Based testing metrics technique that is based on fuzzy logic. The main goal of the proposed technique is to enhance the performance of Assertion-Based software testing in the presence of large numbers of assertions. To evaluate the proposed technique, an experimental study was performed in which the proposed technique is applied on programs with assertions. The result of this experiment shows that the effectiveness and performance of Assertion-Based software testing have improved when applying the proposed testing metrics technique.

In order to test the mediating role of perceived competence between each goal orientation (i.e. task and ego orientations) and intrinsic motivation in a motivational sequence in the context of university education, two models based on the cognitive evaluation theory and the achievement goal theory were tested with 276 Bolivian undergraduate students (138 males, 138 females), who completed Spanish versions of instruments designed to assess motivation, perceived competence, and positive emotions and interest. Two models were found with structural equation modeling techniques, one for ego orientation and one for task orientation. Results showed that perceived competence acts as a good mediator in the relation between ego orientation and intrinsic motivation, and as a partial mediator in the relation between task orientation and intrinsic motivation.
