Observation of particle pairing in a two-dimensional plasma crystal

The observation is presented of naturally occurring pairing of particles and their cooperative drift in a two-dimensional plasma crystal. A single layer of plastic microspheres was suspended in the plasma sheath of a capacitively coupled rf discharge in argon at a low pressure of 1 Pa. The particle dynamics were studied by combining the top-view and side-view imaging of the suspension. Cross analysis of the particle trajectories allowed us to identify naturally occurring metastable pairs of particles. The lifetime of pairs was long enough for their reliable identification.Comment: 5 pages, 4 figure

Applying Recommendations to Align Competences, Methodology, and Assessment in Telematics, Computing, and Electronic Engineering Courses

The alignment between competences, teachinglearning methodologies, and assessment is a key element of European higher education. This paper presents the efforts carried out by six telematics, computer science and electronic engineering education teachers toward achieving this alignment in their subjects. In a joint work with pedagogues, a set of recommended actions are identified. A selection of these actions are applied and evaluated in the six subjects. The cross analysis of the results indicates that the actions allow students to better understand the methodologies and assessments planned for the subjects, facilitate (self-) regulation, and increase students’ involvement in the subjects

VULNERLIZER: Cross-analysis Between Vulnerabilities and Software Libraries

The identification of vulnerabilities is a continuous challenge in software projects. This is due to the evolution of methods that attackers employ as well as the constant updates to the software, which reveal additional issues. As a result, new and innovative approaches for the identification of vulnerable software are needed. In this paper, we present VULNERLIZER, which is a novel framework for cross-analysis between vulnerabilities and software libraries. It uses CVE and software library data together with clustering algorithms to generate links between vulnerabilities and libraries. In addition, the training of the model is conducted in order to reevaluate the generated associations. This is achieved by updating the assigned weights. Finally, the approach is then evaluated by making the predictions using the CVE data from the test set. The results show that the VULNERLIZER has a great potential in being able to predict future vulnerable libraries based on an initial input CVE entry or a software library. The trained model reaches a prediction accuracy of 75% or higher

Cross-analysis of the accessibility instruments

In the following, we look at how the different accessibility instruments presented in section 3 compare on the different aspects: background, conceptual framework and theoretical underpinnings, operational aspects, relevance for planning practice, strengths and limitations, and visualization. We identify, per item, significant similarities and differences and reflect on potential implications for the following steps of the Action

The malleability of disciplinary identity

Master's Project (M.A.) University of Alaska Fairbanks, 2017This paper tracks the progress of a beginning undergraduate writer's disciplinary becoming. Much research in disciplinary identity focuses on graduate students and advanced undergraduate writers; however, sites of disciplinary identity formation also occur early on during the required first-year writing course. These sites are crucial because they inform the student writer's entrance into the academic conversation, and reveal the extent to which early assumptions about disciplinary roles affects further disciplinary identity formation. Drawing from Ivanič's framework of writer identity, this case study reveals the ever-shifting tensions of "disciplinary becoming." The analysis captures how a writer's discursive self shifts from a static disciplinary identity to a more malleable disciplinary identity through a cross-analysis of two separate writing assignments in order to learn how the student's petroleum engineer identity is performed, contradicted and re-negotiated. I argue that this shift will enable writing knowledge transfer and overall identity formation

Thermal comfort and indoor air quality on end-user satisfaction level evaluation in a Nearly Zero Carbon neighbourhood

End-user satisfaction studies in residential buildings has to be approached combining the user’s perspective and technical criteria to consider the complex interactions influencing the building energy performance. Therefore, in this study the physical characteristics of dwellings and their environments are assessed, user satisfaction is examined, and the relationship between them is investigated. The study aims to illustrate the end-user satisfaction in exemplary high performance buildings and to investigate how the users are interacting with these buildings. Examination of the building performance, thermal comfort and indoor air quality are the main focal points of the work. In general, results reflect a significant improvement on the satisfaction level of the inhabitants with the comfort of the dwelling after the refurbishment of the district. Findings from the cross-analysis of both surveys and measurements are used to further refine conclusions and identify the driving factors of the interrelationship between building performance and end-user satisfaction

Corporate Philanthropy in Top Romanian Companies

This paper aims to provide an insight on the CSR activities developed by top Romanian companies and to analyze whether some economic indexes as number of employees and turnover have a considerable impact on the decision of companies to involve in social responsible activities. The approach is based on a cross-analysis of the statistical weight of donations for eight top company donors in 2007 in Romania. By reviewing the results of the research, the author considers the opportunity to develop a case for CSR, even in its basic form: philanthropy, as a premise for long run social performance.corporate philanthropy, corporate social responsibility, microeconomic indexes, stakeholders.

Agriculturale Extension and Speaker Acceptance: A Simple Cross Analysis between Groups at University Stage

Effective communication skills is one of the many abilities that agricultural extensionists should possess. This is because, these officers will be required to disseminate the latest knowledge and introduce new technologies to farmers to fulfil national agricultural policies and vision. Anxiety is a common issue faced by extensionists, especially during oral briefings or presentation and for officers who are still new at their job. The problem could arise from situational or personal effects, which play significant roles in regulating anxiety. Controlled anxiety allows for a remarkable speech delivery and accelerate audience attention and involvement. The study focused on determining the challenges or factors influencing the fluency/smoothness in giving speeches by academic and non-academic personnel in UPMKB. Both groups are irregularly involved in extension services to the Bintulu community. A semi-structured questionnaire was prepared and distributed among 30 respondents. This study used an in-depth interview and content analysis to highlight the challenges among respondents. Our findings indicated two main challenges, namely the occurrence of speech anxiety and insufficient preparation before speech delivery. Older and more experienced respondents (>16 years job experience) showed controllable anxiety compared to the younger ones due to the younger officers limited public speaking experience. The response of the audience during agricultural talks significantly affects the respondent’s anxiety by either reducing or increasing the anxiety through non-verbal communication — moreover, sufficient time to prepare the information for the speech also regulates anxiety in respondents. Therefore, invitation for agricultural extension talks or speeches must consider a speaker’s expertise and provide sufficient advance notice

New intelligent network approach for monitoring physiological parameters : the case of Benin

Benin health system is facing many challenges as: (i) affordable high-quality health care to a growing population providing need, (ii) patients’ hospitalization time reduction, (iii) and presence time of the nursing staff optimization. Such challenges can be solved by remote monitoring of patients. To achieve this, five steps were followed. 1) Identification of the Wireless Body Area Network (WBAN) systems’ characteristics and the patient physiological parameters’ monitoring. 2) The national Integrated Patient Monitoring Network (RIMP) architecture modeling in a cloud of Technocenters. 3) Cross-analysis between the characteristics and the functional requirements identified. 4) Each Technocenter’s functionality simulation through: a) the design approach choice inspired by the life cycle of V systems; b) functional modeling through SysML Language; c) the communication technology and different architectures of sensor networks choice studying. 5) An estimate of the material resources of the national RIMP according to physiological parameters. A National Integrated Network for Patient Monitoring (RNIMP) remotely, ambulatory or not, was designed for Beninese health system. The implementation of the RNIMP will contribute to improve patients’ care in Benin. The proposed network is supported by a repository that can be used for its implementation, monitoring and evaluation. It is a table of 36 characteristic elements each of which must satisfy 5 requirements relating to: medical application, design factors, safety, performance indicators and materiovigilance
