In this paper, a self-tuning control system is proposed to automate materials procurement for largeconstruction projects. The system is planned to be a web-based tool to facilitate the sharing of real time information related to stock level, work progress and material ordering. A prototype of the system was developed and tested by threeprocurement cases in a commercial development project producing encouraging results. The system successfully forecasted the material requirement by tuning the batch order to match with the actual required level.

<P><B>Abstract</B></P><P><B>Objective</B></P><P>Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease with significant immune system aberrations resulting from complex heritable genetics as well as environmental factors. We undertook to study the role of <I>TRAF6</I> as a candidate gene for SLE, since it plays a major role in several signaling pathways that are important for immunity and organ development.</P><P><B>Methods</B></P><P>Fifteen single‐nucleotide polymorphisms (SNPs) across <I>TRAF6</I> were evaluated in 7,490 SLE patients and 6,780 control subjects from different ancestries. Population‐based case–control association analyses and meta‐analyses were performed. <I>P</I> values, false discovery rate q values, and odds ratios (ORs) with 95% confidence intervals (95% CIs) were calculated.</P><P><B>Results</B></P><P>Evidence of associations was detected in multiple SNPs. The best overall <I>P</I> values were obtained for SNPs rs5030437 and rs4755453 (<I>P</I> = 7.85 × 10<SUP>−5</SUP> and <I>P</I> = 4.73 × 10<SUP>−5</SUP>, respectively) without significant heterogeneity among populations (<I>P</I> = 0.67 and <I>P</I> = 0.50, respectively, in Q statistic). In addition, SNP rs540386, which was previously reported to be associated with rheumatoid arthritis (RA), was found to be in linkage disequilibrium with these 2 SNPs (r<SUP>2</SUP> = 0.95) and demonstrated evidence of association with SLE in the same direction (meta‐analysis <I>P</I> = 9.15 × 10<SUP>−4</SUP>, OR 0.89 [95% CI 0.83–0.95]). The presence of thrombocytopenia improved the overall results in different populations (meta‐analysis <I>P</I> = 1.99 × 10<SUP>−6</SUP>, OR 0.57 [95% CI 0.45–0.72], for rs5030470). Finally, evidence of family‐based association in 34 African American pedigrees with the presence of thrombocytopenia was detected in 1 available SNP (rs5030437) with a Z score magnitude of 2.28 (<I>P</I> = 0.02) under a dominant model.</P><P><B>Conclusion</B></P><P>Our data indicate the presence of association of <I>TRAF6</I> with SLE, consistent with the previous report of association with RA. These data provide further support for the involvement of <I>TRAF6</I> in the pathogenesis of autoimmunity.</P>
