Probabilistic Model for M2M in IoT networking and communication
Springer Science + Business Media 2016 Journal of Telecommunication systems Vol.62 No.1
<P>In this paper, a probabilistic model for M2M in IoT networking and communication mode is presented with mobile and dynamic machines in the network. The scenario is considered stochastic and thus probability distribution describing the times between successive machines entry in to the network is predicted by means of a graph. A graph based model is also presented to find the shortest path and lowest cost between machines. For large scale network, parallel M2M establish connection inside a network and are partitioned and dynamically refigured such as IoT. Simulation were performed for multiple M2M array for different state, timing and power consumption along with the scheduling scheme are considered.</P>
Comparison of different Brazilian citrus by-products as source of natural antioxidants
Paula de Paula Menezes Barbosa,Amanda Roggia Ruviaro,Gabriela Alves Macedo 한국식품과학회 2018 Food Science and Biotechnology Vol.27 No.5
Significant amounts of citrus by-products remain after juice processing, which is then used to obtain pectin. The pectin industry then generates a new waste. No study has characterized this residue or suggested applications for it. The main goal of this study was to compare citrus industrial by-products that remain after juice (CJB) and pectin (CPB) extraction, aiming to obtain bioactive compounds. The residues were evaluated for their chemical composition, antioxidant capacity, and polyphenols content. CJB had 2-fold higher total phenols than CPB. Moreover, CJB exhibited higher antioxidant capacity than CPB. Nine polyphenols were detected; hesperidin was the main compound on both residues. CPB had higher content of polyphenols than CJB, which can be attributed to the industry procedure of pectin extraction. Thus, this study provides support for the reuse of CPB to obtain nutraceutical compounds, converting waste into added-value products.

Microbial oils enriched in essential polyunsaturatedfatty acids can be used as nutritionalcomplements. In order to improve the lipid yields and lipidprofiles of 2 Yarrowia lipolytica strains, the effects ofmedium components and culture conditions were investigatedusing shake flasks. Under optimized conditions (cultivationfor 3 days at 25ºC and 150 rpm, using peptone as anitrogen source and glucose as a carbon source), thebiomass, lipid yield, and lipid content reached 6.75 g/L,3.48 g/L, and 51.55% for Y. lipolytica QU22, and 6.85 g/L,3.52 g/L, and 51.38% for Y. lipolytica QU137, respectively. Using a shaking speed of 150 rpm, unsaturated fatty acidsconstituted 87.96% (QU22) and 87.08% (QU137) of thetotal lipids produced by these strains, with 9.52 and 7.86%of alpha-linolenic acid, respectively. The strains are suitablecandidates for fermentation processes involving essentialpolyunsaturated fatty acid (PUFA) production.
Fostering Learners' Intercultural Competence with CALL
Paula Garrett-Rucks 한국외국어교육학회 2017 Foreign languages education Vol.24 No.2
There is increasing pressure on world language educators to expand the cultural instruction in their curriculum and to advocate for their language programs as a means to prepare learners with 21st century skills (The Four Cs: Creativity, Communication, Collaboration, and Critical thinking). In similar vein, ACTFL’s Global Competence Position Statement (2014) further described the need for language instructors to foster learners’ interactional abilities and behaviors to perform effectively and appropriately when interacting with others who are linguistically and culturally different from self. Yet many language educators are confused about best-teaching practices during this transition time from methods that focus primarily on students’ ability to use the language to communicate, to a time where it is increasingly emphasized that students should access content information through the language for meaningful cultural reflection. This paper demystifies some confusion about fostering learners’ intercultural competence in instructed language learning and concludes with a variety of tools and techniques to integrate computer-assisted language learning (CALL) and meaningful cultural inquiry at beginning levels of instruction.
Norm Internalization and Disability-inclusive Elections in the Philippines
Paula Bianca P. Lapuz,FRANCISCO A. MAGNO 이화여자대학교 국제지역연구소 2019 Asian International Studies Review Vol.20 No.2
This article reviews the emergence of international norms connectedwith disability-inclusive elections and provides evidence of howthey were cascaded and internalized in the Philippines. It examinesthe experience of the persons with disabilities (PWD) sector in thecampaign for disability-inclusive elections. With the support ofcivil society organizations and international development partners,the PWD sector lobbied for the passage of the Accessible PollingPlace (APP) Act which aims to improve the enfranchisement ofPWDs. Primary data were collected through key informantinterviews and focus group discussions, while a contextualanalysis of relevant secondary documents was conducted to showproof of norm internalization in the establishment of disabilityinclusiveelections.
A partial factors methodology for structural safety assessment in non-linear analysis
Paula M. R. P. Castro,Raimundo M. Delgado,Jose M. A. Cesar de Sa 한국계산역학회 2005 Computers and Concrete, An International Journal Vol.2 No.1
In the present structural codes the safety verification is based on a linear analysis of the structure and the satisfaction of ultimate and serviceability limit states, using a semi-probabilistic security format through the consideration of partial safety factors, which affect the action values and the characteristic values of the material properties. In this context, if a non-linear structural analysis is wanted a difficulty arises, because the global safety coefficient, which could be obtained in a straightforward way from the non-linear analysis, is not directly relatable to the different safety coefficient values usually used for the different materials, as is the case for reinforced concrete structures. The work here presented aims to overcome this difficulty by proposing a methodology that generalises the format of safety verification based on partial safety factors, well established in structural codes within the scope of linear analysis, for cases where non-linear analysis is needed. The methodology preserves the principal assumptions made in the codes as well as a reasonable simplicity in its use, including a realistic definition of the material properties and the structural behaviour, and it is based on the evaluation of a global safety coefficient. Some examples are presented aiming to clarify and synthesise all the options that were taken in the application of the proposed methodology, namely how to transpose the force distributions obtained with a non-linear analysis into design force distributions. One of the most important features of the proposed methodology, the ability for comparing the simplified procedures for second order effects evaluation prescribed in the structural codes, is also presented in a simple and systematic way. The potential of the methodology for the development and assessment of alternative and more accurate procedures to those already established in codes of practice, where non-linear effects must be considered, is also indicated.
