Juno : a middleware platform for supporting delivery-centric applications
No full textThis paper proposes a new delivery-centric abstraction, which extends the existing content-centric networking API. A delivery-centric abstraction allows applications to generate content requests agnostic to location or protocol, with the additional ability to stipulate high-level requirements regarding such things as performance, security and resource consumption. Fulfilling these requirements, however, is complex as often the ability of a provider to satisfy requirements will vary between different consumers and over time.Therefore, we argue that it is vital to manage this variance to ensure an application fulfils its needs. To this end, we present the Juno middle ware, which implements delivery-centric support using a re-configurable software architecture to (i) discover multiple sources of an item of content; (ii) model each source’s ability to provide the content; then (iii) adapt to interact with the source(s) that can best fulfil the application’s requirements. Juno therefore utilises existing providers in a backwards compatible way, supporting immediate deployment. This paper evaluates Juno using Emulab to validate its ability to adapt to its environment

Setting the best view of a virtual teacher in a mixed reality physical-task learning support system
No full textIn this research, we investigated the virtual teacher’s positions and orientations that led to optimal learning outcome in mixed-reality environment. First, this study showed that the virtual teacher’s position
and orientation have an effect on learning efficiency, when some teacher-settings are more comfortable
and easy to watch than others. A sequence of physical-task learning experiments have been conducted
using mixed-reality technology. The result suggested that the virtual-teacher’s close side-view is the
optimal view for learning physical-tasks that include significant one-hand movements. However, when
both hands are used, or rotates around, a rotation-angle adjustment becomes necessary. Therefore, we
proposed a software automatic-adjustment method governing the virtual teacher’s horizontal rotation
angle, so that the learner can easily observe important body motions. The proposed software method was
revealed to be effective for motions that gradually reposition the most important moving part. Finally,
to enhance the proposed method in the future, we conducted an experiment to find out the effect of
setting the vertical view-angle. The result recommended that the more motion’s rotation involved the
more vertical view angles are wanted to see the whole motion clea
Does Entrepreneurship Education Have a Role in developing Entrepreneurial Skills And Ventures' Effectiveness?,
No full textThe purpose of the paper is to examine the impact of entrepreneurship
education and training on the development and enhancement of
entrepreneurial skills that may be essential to improve ventures'
effectiveness. One hundred and seventy entrepreneurs and prospective
entrepreneurs were surveyed in the United States to determine their
motivations for business ownership and assess their perceived factors that
may have contributed to the success or failure of their ventures. The
findings clearly indicate that there is causal linkages between
entrepreneurial education (managerial skills), social competence
(interpersonal skills), and to a greater degree, basic entrepreneurial training
skills and ventures' effectiveness. They were statistically significant
confirming prior expectation of the significant value of entrepreneurship
education. The data demonstrates that the entrepreneurial education and
training programs appear to create openness, confidence, and trust among
the participants in this study. However, the type of entrepreneurship
education must be coupled with content that is rich in learning principles,
innovation, and reflection in order to enhance ventures' effectiveness
