While there are known performance trade-offs between database page buffer pool and query execution memory allocation policies, little has been written on the impact of query compilation memory use on overall throughput of the database management system (DBMS). We present a new aspect of the query optimization problem and discuss a solution implemented in Microsoft SQL Server 2005. The solution ...

This study provides valuable support for successful decision making in network hierarchical structures. The balanced scorecard (BSC) is a measurement system that requires a balanced set of financial and nonfinancial measures. This study examined both qualitative and quantitative data for the proposed hybrid analytical method. Although numerous studies have been conducted in industry and academi...

Aspects avoid tangled solutions for cross-cutting design concerns. Unfortunately there are various reasons why it may hard to use an aspect language or aspect composition framework as a solution, even though developers are faced with crosscutting design concerns or tangled code structures. For instance, certain limitations of specific aspect composition frameworks might hinder the use of aspect...

Operations Research has addressed a variety of environmental problems outside the traditional supply chain management area such as remanufacturing, reverse logistics, and waste management. Supply chain sustainability, which includes designing green supply chains, will gain much more attention in the future. Indeed, most companies are still in the early stage of considering a green initiative. T...

It is essential to control VDD and VTH for low-power, high-speed CMOS design. In this paper, it is shown that these two parameters can be controlled by designers as objectives of design optimization to find better trade-offs between power and speed. Quantitative analysis of trade-offs between power and speed is presented. Some of the popular circuit techniques and design examples to control VDD...
