As the nature of online gaming changes to accomodate vast, persistent virtual worlds, there is a growing need to populate them with inhabitants capable of dynamic, adaptable, fruitful interactions with players. In this paper we argue that by separately placing abstract compentencies in the agent and concrete domain knowledge in the environment, we can build simple intelligences that exhibit sop...

Elevated rail transit has been developed in some big cities in China in recent years. However, specialized codes for design of the bridges in the elevated rail transit system have not yet been established. Based on the prestressed concrete (PC) box girder bridges on Guangzhou metro line 4, some technical features of design principle and technology requisition, ensemble plan and design load of b...

Due to growing environmental concerns of the cement industry, alternative cement technologies have become an area of increasing interest. It is now believed that new binders are indispensable for enhanced environmental and durability performance. Self-compacting Geopolymer concrete is an innovative method and improved way of concreting operation that does not require vibration for placing it an...

This paper presents an experimental program dealing with the shear strengthening with FRP systems of URM walls built with concrete and clay units. Ten concrete and five clay masonry panels, strengthened with FRP composites in the form of laminates and rods, and stainless steel, were loaded along the wall diagonal to observe their shear performance. The dimension of the concrete masonry panels w...

The type of lightweight aggregate and its volume fraction in a mix determine the density of lightweight concrete. Minimizing the density obviously requires a higher volume fraction, but this usually causes aggregates segregation in a conventional mixing process. This paper proposes a two-stage casting process to produce a lightweight concrete. This process involves placing lightweight aggregate...

Rubblization is one of the surface preparation techniques before placing a Hot Mix Asphalt (HMA) overlay that involves breaking the Portland Cement Concrete (PCC) pavement into pieces. This paper describes the structural assessment related to the long term performance of rubblized concrete pavements in Iowa. The structural performance of seven representative in-service rubblized concrete paveme...

In this report, we conducted a questionnaire survey targeting contractors who perform placing and compaction of concrete, investigated the actual conditions compaction. As result, description in JASS 5 is standard for ordinary so number workers, rod diameter internal vibrators, etc. been determined according to construction conditions. addition, there were many opinions that it was expected pos...
