Towards a Technology Agnostic Approach to Developing Mobile Applications and Services

Journal of Software Engineering and Applications 2017年第6期10卷 500-528页

作者： Ian warren Andrew Meads Department of Computer Science University of Auckland Auckland New Zealand

Today’s mobile devices and networks enable the development of novel mobile service applications. Developing such applications raises many challenges including heterogeneity in terms of mobile operating systems and APIs, service availability and scalability, and providing for the diverse communication needs of different applications. In this paper, we present an overview of the Odin middleware platform whose aim is to address these challenges. Odin utilises a surrogate-based architectural model to promote a mobile service’s scalability and availability. The middleware is reconfigurable, allowing mobile applications to adapt to changing operating conditions and minimise resource consumption. It also includes an optimised communication channel that masks the complexity of interacting with mobile services over mobile telecommunications networks. Using Odin’s interfaces and standards compliance, mobile applications and services with consistent communication behaviour can be easily implemented on heterogeneous platforms. Through quantitative evaluation, Odin’s message-based communication primitives have been demonstrated to perform favourably with leading industry push messaging providers.

Reconsideration of the phylogenetic positions of three stichotrichous genera Holosticha,Anteholosticha and Pseudokeronopsis (Spirotrichea:Ciliophora) inferred from complete SSU rRNA gene sequences

The small subunit rRNA (SSU rRNA) gene for six marine stichotrichs, Pseudokeronopsis carnea, P. flava, Holosticha heterofoissneri, H. diademata, H. bradburyae and Anteholosticha manca, was sequenced and characterized. Using this molecular information, the phylogenetic positions of three related genera, Pseudokeronopsis, Holosticha and Anteholosticha were determined. The results indicate that the family Urostylidae is clearly separated from the family Pseudokeronopsidae. The present phylogenetic analyses unambiguously placed Pseudokeronopsis close to Holosticha, and support the conclusion that these genera should be regarded as the members of the order Urostylidae within the stichotrich clade. Furthermore, the results of this study also support the monophyly of the genus Pseud-okeronopsis, the redefinition of Holosticha s. str. and the placement of Anteholosticha in a clade separate from Holosticha.

Inflatable rock bolt bond strength versus rock mass rating (RMR)： A comparative analysis of pull-out testing data from underground mines in Nevada

引用

International Journal of Mining Science and Technology 2016年第1期26卷 19-22页

作者： Barnard Chase Kallu Raj R. warren Sean Thareja Rahul Department of Mining Engineering University of Nevada Reno 89557 USA

The purpose of this paper is to establish confidence in anticipated minimum bond strength for inflatable rock bolts by comparing the bond strength to variable geotechnical conditions using the rock mass rating(RMR) system. To investigate a correlation between these parameters,the minimum bond strength of pull-out tested inflatable rock bolts was compared to the RMR of the rock in which these bolts were placed. Bond strength vs. RMR plots indicate that expected minimum bond strength is positively correlated with RMR; however,the correlation is not strong. Cumulative percent graphs indicate that 97% of pull-out tests result in a minimum bond strength of 3.3 and 1.7 ton/m in RMR P 45 and <45,*** lower bond strengths are more commonly encountered in low RMR ground,high bond strengths are possible as well,yielding higher variability in bond strengths in low RMR ground. Bond strength of friction bolts relies on contact between the rock bolt and drill hole. Experience in Nevada indicates that RMR is known to affect both the quality and consistency of drill holes which likely affects bond strength. Drilling and bolting in low RMR ground is more sensitive to drilling and bolting practices,and strategies for maximizing bond strength in these conditions are discussed.
