Tangential strain-based criteria for mixed-mode I/II fracture toughness of cement concrete
No full textExperimental and theoretical works are performed on the mixed-mode I/II brittle fracture of cement concrete tested by edge cracked semicircular bend specimens. Theoretical background of the traditional fracture criteria including strain energy density, maximum tangential stress, and maximum tangential strain (MTSN) are introduced. The ability of each fracture criterion in prediction of the fracture test data is investigated. The comparison between the evaluations by the traditional criteria and the experimental data shows that none of them are capable of successfully estimating the fracture resistance of cement concrete. An enhanced version of the MTSN criterion is then employed to predict the test data. It is demonstrated that the extended MTSN criterion can successfully predict the test data in a higher accuracy than traditional criteria. © 2017 Wiley Publishing Ltd
EMTSN criterion for evaluating mixed mode I/II crack propagation in rock materials
No full textThis paper investigates the results of brittle fracture in rock materials subjected to the mixed mode I/II loading using different fracture criteria. Two sets of mixed mode fracture test data in the entire range of mode mixity, from pure mode I to pure mode II, reported in the literature for semi-circular and triangular shape specimens and subjected to three point bend loading (i.e. SCB and ECT specimens) are utilized to study the brittle fracture in two marble rocks. First, the onset of fracture initiation is examined by different conventional fracture criteria including Maximum Tangential Stress (MTS) and Maximum Tangential Strain (MTSN) criteria. It is shown that these two conventional fracture criteria, which only consider singular crack tip stress/strain terms, are not able to accurately predict the mixed mode fracture test data. The experimental mixed mode fracture toughness data are then predicted by an extended version of the maximum tangential strain (EMTSN) criterion which takes into account the effect of first nonsingular strain term as well as the singular strain components. It is found that both mixed mode fracture toughness results of the investigated rock materials and the crack propagation direction can be predicted successfully by the EMTSN criterion.

The adoption of capability maturity model (CMM) in software development and integration organisation in Klang Valley / Ili Bazilah Razmi
No full textWhat is CMM and why is it important? CMM is the Capability Maturity Model
developed by the Software Engineering Institute (SEI) at Carnegie Mellon
University. It is a model that provides a way to assess the maturity (i.e. strength) of
the processes used by an organization to develop and support its information
systems. Since these processes are the tools by which the organization accomplishes
its work, the higher their quality, the higher the performance of the organization. An
organization that employs processes that comply with a higher CMM level produces
higher quality work products faster, for less cost, and with greater consistency.
However, the adoption of new practices takes time and planning. When
implementing new practices, it is important not to underestimate the effort for the
new behaviors to become common practice within the organization. The research
paper will be looking at the factors influencing the CMM adoption and the benefits it
perceive fiom it. Approximately 100 questionnaires were distributed to the staffs in
those eight organisations names are not disclosed in this research due to
confidentiality reason. A phone interview was also conducted to gain information
personally fix>m the managers. Statistical analysis was carried out on data collected
fix)m 50 completed questionnaires. As of the results, factors influencing the adoption
process of CMM and the benefits it provided for all these eight organisations were
identified
Can Asia Sustain an Export-Led Growth Strategy in the Aftermath of the Global Crisis? An Empirical Exploration
No full textMany developing countries have attempted to pursue the East Asian growth model in recent decades. This model is widely perceived to have been based on export-led growth. Given that developed countries are likely to grow at a slower rate and be less willing to run trade deficits in the post-financial-crisis world can this growth model be sustained? Using panel data for Asian countries, this paper contributes to addressing this question by distinguishing between different kinds of export- and tradable-led growth in order to more precisely identify the nature of growth in the pre-crisis decades.export-led growth; tradable-led growth; global imbalances; industrialization; capital accumulation

The Exchange Rate, Diversification, and Distribution in a Modified Ricardian Model with a Continuum of Goods
No full textSeveral recent empirical and theoretical studies have revived interest in the relationship between the level of the exchange rate and economic development. This paper develops a dynamic model based on the Ricardian framework with a continuum of goods to consider the issue from a somewhat different perspective. While directly suppressing the real wage could also lead to diversification, what makes nominal devaluation a particularly useful tool is that it makes it possible to expand domestic profits while limiting internal distributional conflict and the ensuing negative effects on development.economic development; exchange rate

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
