Permutations Containing Many Patterns

It is shown that the maximum number of patterns that can occur in a permutation of length $n$ is asymptotically $2^n$. This significantly improves a previous result of Coleman

Flow visualization and flow field measurements of a 1/12 scale tilt rotor aircraft in hover

The results are given of flow visualization studies and inflow velocity field measurements performed on a 1/12 scale model of the XV-15 tilt rotor aircraft in the hover mode. The complex recirculating flow due to the rotor-wake-body interactions characteristic of tilt rotors was studied visually using neutrally buoyant soap bubbles and quantitatively using hot wire anemometry. Still and video photography were used to record the flow patterns. Analysis of the photos and video provided information on the physical dimensions of the recirculating fountain flow and on details of the flow including the relative unsteadiness and turbulence characteristics of the flow. Recirculating flows were also observed along the length of the fuselage. Hot wire anemometry results indicate that the wing under the rotor acts to obstruct the inflow causing a deficit in the inflow velocities over the inboard region of the model. Hot wire anemometry also shows that the turbulence intensities in the inflow are much higher in the recirculating fountain reingestion zone

Improving Students’ Reading Comprehension of Narrative Text through Comic Strips

AbstractThe aim of this research was to improve the students’ reading ability, especially in comprehending a narrative text. This research was conducted at the tenth grade students of SMAN 2 Sungai Raya in academic year 2016/2017. In this research, the subject was XA that consists of 34 students. The researcher conducted a classroom action research. The data were collected by both measurement technique and observation. The tools of data collecting were observation checklist, field note, and test.Comic strips was used as the teaching media in this research which was conducted in two cycles. The research findings showed that students’ individual score, on the first cycle there were 18 students of 34 students passed the test. On the second cycle, 29 students passed the test. The reading comprehensionofnarrative text of the tenth grade students of A class of SMAN 2 Sungai Raya in academic year 2016/2017 improved by using comic stripsmedia Keywords: Comic Strips, Narrative Text, Readin

The Role of Social Presence and Moderating Role of Computer Self Efficacy in Predicting the Continuance Usage of E-Learning Systems

The continuous growth of the electronic learning (e-learning) market has drawn a lot of discussion about the effectiveness of virtual learning environments (VLE). The initial emphasis of e-learning in the context of information technology skills training continues to be relevant. The success of an e-learning program in information technology (IT) may require users to be equipped with a certain degree of computer self-efficacy and affect for information systems. These factors may, in turn, influence the satisfaction level of online learners and their intention to continue using the e-learning system. Therefore, it is plausible that these factors may be as important as or more important than the design of an effective VLE in an IT context. This paper blends the Computer Self-Efficacy (CSE) and Expectation-Confirmation Models (ECM), and assesses their applicability on the intention of online learners who continue using the e-learning system as a vehicle to assimilate IT skills. Second, it theorizes the causal relationship of the factors of Perceived Usefulness, Confirmation, Satisfaction, and IS Continuance in the e-learning context. Finally, it assesses the relative importance of social presence in helping online learners to prevail over the online asynchronous environment. Our results indicate that, in the context of assimilating IT skills, there is not a significant relationship among the CSE of online learners, their perceived usefulness, confirmation, and satisfaction level. As a moderating factor, computer self-efficacy does not have significant influence on learning outcomes. For knowledge long transfer, social presence was shown to have an effect in different VLEs

The impact of arthritis on the educational and early work experiences of young people:a qualitative secondary analysis

Introduction: Young people’s transition into adulthood is intertwined with the worlds of education and work. Poor health in adolescence has been associated with poorer education and employment outcomes in adulthood. This paper explores the impact of arthritis on the educational and early work experiences of young people with arthritis. Methods: We undertook a supplementary secondary analysis of a qualitative dataset comprising narrative and semi-structured interviews of 39 young people who had been diagnosed with arthritis in childhood, adolescence or young adulthood. Results: Our findings illustrate how young people living with arthritis are faced with a range of added disruptions and challenges in their educational/vocational lives. There is an important element of resilience associated with the process of making a career choice and acting upon personal aspirations. Appropriate support and flexibility in the workplace/educational setting can enable successful outcomes, but disclosure is not a straightforward process for young people living with arthritis. Conclusions: It is paramount that health providers consistently and effectively address self-advocacy skills with the young person, particularly during educational and vocational transitions. Alongside this, there is the need to further strengthen the health-school/work interface to ensure that young people living with chronic illness can meet their full potential in adulthood

The Goldilocks Approach: A Review of Employing Design of Experiments in Prokaryotic Recombinant Protein Production

The production of high yields of soluble recombinant protein is one of the main objectives of protein biotechnology. Several factors, such as expression system, vector, host, media composition and induction conditions can influence recombinant protein yield. Identifying the most important factors for optimum protein expression may involve significant investment of time and considerable cost. To address this problem, statistical models such as Design of Experiments (DoE) have been used to optimise recombinant protein production. This review examines the application of DoE in the production of recombinant proteins in prokaryotic expression systems with specific emphasis on media composition and culture conditions. The review examines the most commonly used DoE screening and optimisation designs. It provides examples of DoE applied to optimisation of media and culture conditions
