The future of Malay–Chinese relations in Malaysia

In this chapter, the Malay–Chinese relation is examined by considering the history and nature of the relationship, the ensuing intergroup conflict, and the steps taken by the government and civil society groups to address the conflict. Finally, a psychocultural approach to building peace between the two groups is proposed

Knowledge-based Lean Six Sigma Maintenance System for Sustainable Buildings

YesPurpose– This paper develops a Knowledge-based (KB) System for Lean Six Sigma (LSS) Maintenance in environmentally Sustainable Buildings (Lean6-SBM). Design/methodology/approach– The Lean6-SBM conceptual framework has been developed using the rule base approach of KB system and joint integration with Gauge Absence Prerequisites (GAP) technique. A comprehensive literature review is given for the main pillars of the framework with a typical output of GAP analysis. Findings– Implementation of LSS in the sustainable building maintenance context requires a pre-assessment of the organisation’s capabilities. A conceptual framework with a design structure is proposed to tackle this issue with the provision of an enhancing strategic and operational decision making hierarchy. Research limitations/implications– Future research work might consider validating this framework in other type of industries. Practical implications– Maintenance activities in environmentally sustainable buildings must take prodigious standards into consideration and, therefore, a robust quality assurance measure has to be integrated. Originality/value– The significance of this research is to present a novel use of hybrid KB/GAP methodologies to develop a Lean6-SBM system. The originality and novelty of this approach will assist in identifying quality perspectives while implementing different maintenance strategies in the sustainable building context.Ministry of Defence Engineering Services (Sultanate of Oman

Transparent Control Independence (TCI)

Superscalar architectures have been proposed that exploit control independence, reducing the performance penalty of branch mispredictions by preserving the work of future mispredictionindependent instructions. The essential goal of exploiting control independence is to completely decouple future mispredictionindependent instructions from deferred misprediction-dependent instructions. Current implementations fall short of this goal because they explicitly maintain program order among misprediction-independent and misprediction-dependent instructions. Explicit approaches sacrifice design efficiency and ultimately performance. We observe it is sufficient to emulate program order. Potential misprediction-dependent instructions are singled out a priori and their unchanging source values are checkpointed. These instructions and values are set aside as a “recovery program”. Checkpointed source values break the data dependencies with comingled misprediction-independent instructions – now long since gone from the pipeline – achieving the essential decoupling objective. When the mispredicted branch resolves, recovery is achieved by fetching the self-sufficient, condensed recovery program. Recovery is effectively transparent to the pipeline, in that speculative state is not rolled back and recovery appears as a jump to code. A coarse-grain retirement substrate permits the relaxed order between the decoupled programs. Transparent control independence (TCI) yields a highly streamlined pipeline that quickly recycles resources based on conventional speculation, enabling a large window with small cycle-critical resources, and prevents many mispredictions from disrupting this large window. TCI achieves speedups as high as 64 % (16 % average) and 88% (22 % average) for 4-issue and 8-issue pipelines, respectively, among 15 SPEC integer benchmarks. Factors that limit the performance of explicitly ordered approaches are quantified

Radiographic evaluation of dental age maturity in 3–17-years-old saudi children as an indicator of chronological age

Objective: This study was aimed to evaluate the dental age in Saudi children from panoramic radiographs using the Demirjian method to estimate their chronological age. Materials And Methods: This retrospective cross-sectional study consisted of 1902 panoramic radiographs of 955 boys and 947 girls between the ages of 3–17 years. All children were placed in the age group closest to their chronological age. The dental age was scored on all seven left mandibular teeth by calibrated examiners. Bivariate analyses using the t-test and Pearson correlation were performed. Results: There was significant difference in both boys and girls in all the age groups between their chronological age and dental age. Even though there was a slight overestimation in boys in some age groups and slight underestimation in girls in some groups, correlation analysis showed that there was a highly significant correlation between the chronological age and dental age for both boys (r2 = 0.96, P < 0.001) and girls (r2 = 0.98, P < 0.001). Moreover, correlation analyses for each age group showed a significant correlation between the chronological age and the dental age, using the Demirjian method, in most age groups (P < 0.01). When comparing the maturation score between boys and girls, the Student's t-test showed that there were no statistical differences between boys and girls in most age groups. Conclusion: Saudi boys and girls living in the western region of Saudi Arabia exhibited similar pattern of dental development when compared to the Demirjian method. Hence, the Demirjian method could be used as reference in children from the western region of Saudi Arabia

Virtual Multiprocessor: An Analyzable, High-Performance Microarchitecture For Real-Time Computing

The design of a real-time architecture is governed by a trade-off between analyzability necessary for real-time formalism and performance demanded by high-end embedded systems. We reconcile this trade-off with a novel Real-time Virtual Multiprocessor (RVMP). RVMP virtualizes a single in-order superscalar processor into multiple interference-free different-sized virtual processors. This provides a flexible spatial dimension. In the time dimension, the number and size of virtual processors can be rapidly reconfigured. A simple real-time scheduling approach concentrates scheduling within a small time interval, producing a simple repeating space/time schedule that orchestrates virtualization. RVMP successfully combines the analyzability (hence real-time formalism) of multiple processors with the flexibility (hence high performance) of simultaneous multithreading (SMT). Worst-cas
