ENHANCING THE EFFICIENCY OF COMMUNICATION PROGRAMS FOR STUDENT ENROLLMENT AT UNIVERSITIES THROUGH RECIPIENT FEEDBACK (SURVEY OF STUDENTS AT DALAT UNIVERSITY IN 2021)

Researching recipient feedback is one of the important actions to enhance the quality of the communication process. This study was conducted to provide some solutions to improve the effectiveness of Dalat University’s enrollment communication process by analyzing student feedback. A survey was conducted in 2021 with a sample of 655 students from Dalat University. The results showed that students mainly knew about Dalat University through word of mouth and the Facebook channel, and that tuition fees, the benchmark, and geographical location were the main reasons students chose the university. In addition, most students showed an interest in receiving content in the form of short videos. The research results can be applied by the communication department of Dalat University and can contribute to the field of university communication research, which has not received much attention in Vietnam

Autonomous Robotic System using Non-Destructive Evaluation methods for Bridge Deck Inspection

Bridge condition assessment is important to maintain the quality of highway roads for public transport. Bridge deterioration with time is inevitable due to aging material, environmental wear and in some cases, inadequate maintenance. Non-destructive evaluation (NDE) methods are preferred for condition assessment for bridges, concrete buildings, and other civil structures. Some examples of NDE methods are ground penetrating radar (GPR), acoustic emission, and electrical resistivity (ER). NDE methods provide the ability to inspect a structure without causing any damage to the structure in the process. In addition, NDE methods typically cost less than other methods, since they do not require inspection sites to be evacuated prior to inspection, which greatly reduces the cost of safety related issues during the inspection process. In this paper, an autonomous robotic system equipped with three different NDE sensors is presented. The system employs GPR, ER, and a camera for data collection. The system is capable of performing real-time, cost-effective bridge deck inspection, and is comprised of a mechanical robot design and machine learning and pattern recognition methods for automated steel rebar picking to provide realtime condition maps of the corrosive deck environments

BiplotGUI: Interactive Biplots in R

Biplots simultaneously provide information on both the samples and the variables of a data matrix in two- or three-dimensional representations. The BiplotGUI package provides a graphical user interface for the construction of, interaction with, and manipulation of biplots in R. The samples are represented as points, with coordinates determined either by the choice of biplot, principal coordinate analysis or multidimensional scaling. Various transformations and dissimilarity metrics are available. Information on the original variables is incorporated by linear or non-linear calibrated axes. Goodness-of-fit measures are provided. Additional descriptors can be superimposed, including convex hulls, alpha-bags, point densities and classification regions. Amongst the interactive features are dynamic variable value prediction, zooming and point and axis drag-and-drop. Output can easily be exported to the R workspace for further manipulation. Three-dimensional biplots are incorporated via the rgl package. The user requires almost no knowledge of R syntax.

The early stages of heart development: insights from chicken embryos

The heart is the first functioning organ in the developing embryo and the detailed understanding of the molecular and cellular mechanisms involved in its formation provides insights into congenital malformations affecting its function and therefore the survival of the organism. Because many developmental mechanisms are highly conserved, it is possible to extrapolate from observations made in invertebrate and vertebrate model organisms to human. This review will highlight the contributions made through studying heart development in avian embryos, particularly the chicken. The major advantage of chick embryos is their accessibility for surgical manipulations and functional interference approaches, both gain- and loss-of-function. In addition to experiments performed in ovo, the dissection of tissues for ex vivo culture, genomic or biochemical approaches, is straightforward. Furthermore, embryos can be cultured for time-lapse imaging, which enables tracking of fluorescently labeled cells and detailed analyses of tissue morphogenesis. Owing to these features, investigations in chick embryos have led to important discoveries, often complementing genetic studies in mouse and zebrafish. As well as including some historical aspects, we cover here some of the crucial advances made in understanding of early heart development using the chicken model

Kinematics of Herbig-Haro Objects and Jets in the Orion Nebula

We have surveyed the inner 5' of the Orion Nebula by means of Halpha and [NII] Fabry-Perot imaging spectroscopy to present a kinematical study of the Herbig-Haro objects in the nebula. The objects studied in this work are HH 202, 203, 204, 529, 269 and other associated features. For HH 202 we find new features that, because of their high velocities (up to 100 km/seg) indicate the presence of an outflow that probably is a HH flow not catalogued previously. HH 202 could be only a part of this larger outflow. Large internal motions are found in the fainter regions of HH 203-204, as well as evidence of transverse density gradients that could account for the asymmetry in the brightness distribution of HH 204. We report for the first time a high blueshifted velocity (-118 km/seg) associated with HH 204, and show that the apex of HH 204 is indeed the zone of maximum velocity, in agreement with bow shock models. We also studied the radial velocity field of HH 269 finding features associated with the HH object. From our studies, we find kinematic evidence that suggests that HH 203-204 and HH 202 are part of a big (aprox. 0.55 pc) bipolar HH outflow.Comment: 24 pages, 10 figures (in three jpg files).

Randomness in post-selected events

Bell inequality violations can be used to certify private randomness for use in cryptographic applications. In photonic Bell experiments, a large amount of the data that is generated comes from no-detection events and presumably contains little randomness. This raises the question as to whether randomness can be extracted only from the smaller post-selected subset corresponding to proper detection events, instead of from the entire set of data. This could in principle be feasible without opening an analogue of the detection loophole as long as the min-entropy of the post-selected data is evaluated by taking all the information into account, including no-detection events. The possibility of extracting randomness from a short string has a practical advantage, because it reduces the computational time of the extraction. Here, we investigate the above idea in a simple scenario, where the devices and the adversary behave according to i.i.d. strategies. We show that indeed almost all the randomness is present in the pair of outcomes for which at least one detection happened. We further show that in some cases applying a pre-processing on the data can capture features that an analysis based on global frequencies only misses, thus resulting in the certification of more randomness. We then briefly consider non-i.i.d strategies and provide an explicit example of such a strategy that is more powerful than any i.i.d. one even in the asymptotic limit of infinitely many measurement rounds, something that was not reported before in the context of Bell inequalities.Comment: similar to published version, new section (III) on photonic experiment

Die verband tussen taak- en egobetrokkenheid en selfverwante faktore in spansport met besondere verwysing na hoerskolerugby

In this article we investigate the possible relation between task and ego involvement and factors related to the self of male adolescent rugby players. In task-involved sport participation (high school rugby, in this case), skills development is emphasized, evaluation of achievement is self-referenced, and success is experienced when learning takes place, when a task is mastered, or when there is improvement in the execution of tasks. Success is attributed to effort. In ego-involved sport participation (high-school rugby) objective outcomes are emphasised (e.g. winning), evaluation of achievement is norm based, and success is experienced when own achievements are favourably compared to those of other sport participants. Success is attributed to natural ability. The empirical study showed a positive relation between task-involved high school rugby participation and the global, personal, and social self. A negative relation between ego-involved high school rugby participation and the physical self was found. South African Journal of Education Vol.24(3) 2004: 200-20

Innovative chili dispenser to establish memory fence dynamics at crop-wildlife interfaces for effective long term human-elephant conflict mitigation, An

Moderator: Stewart Breck.Presented at the 8th international congress for wildlife and livelihoods on private and communal lands: livestock, tourism, and spirit, that was held on September 7-12, 2014 in Estes Park, Colorado.Video presenter: Sébastien Le Bel.With elephant populations in southern Africa increasing at 5% per annum, local communities living in marginal land adjacent to protected areas are faced with increasing occurrences of human-elephant conflict. If this situation is not addressed, elephant populations will have to be reduced and condemned to survive in fenced protected areas while the negative attitudes of humans towards wildlife impact becomes engrained in the minds of many people. Recent mitigation strategies were developed aiming at enhancing existing traditional approaches and improving upon their effectiveness. An innovative chili pepper dispenser was developed to apply pepper directly at the offending elephant, teaching them to respect passive repellents. This concept mimics interactions between animal species to form an effective form of a virtual fence. The advanced chili applicator, developed in a hand held version, is the 'Mhiripiribomba' and the ambush version is the 'Ambushchillibomba'. They fire ping pong balls, filled with a concentrated chili liquid, at speeds of 250ft/sec that burst on contact on or near the elephant, atomizing the concentrate into a fine spray, and creating a deterrent. After hundreds of tests in southern Africa, the industrial version of the 'Mhiripiribomber' offers an opportunity to disseminate this tool at low cost. Combined with sustainable revenues from wildlife, the improvement of mitigation measures with this chili dispenser will increase the wildlife acceptance capacity that the human community is willing to tolerate. Through the creation of memory fences, it will facilitate elephants respecting human activities and aid the acceptance of wildlife corridor in crop land
