In the present study, different cobalt precursors, such as cobalt acetylacetonate (CoAA), cobalt acetate (CoAC), cobalt nitrate (CoN) and cobalt chloride (CoCL), were employed to synthesize the cobalt on cobalt-aluminate catalysts by the solvothermal proc... see more

In this research, characteristics of methylcellulose (MC) films modified with two crosslinking methods were investigated. The first method was the use of a glutaraldehyde (GA) crosslinker to promote hemi-acetal linkages between MC chains. The second one w... see more

Pattanawong Chokratanasombat, Ekasit Nisaratanaporn

A facile polyol process for producing copper powders with controllable size is described here. The copper powders have been readily synthesized by the reduction of copper (II) nitrate trihydrate with the solution of glycerol and sodium hydroxide. The X-ra... see more

Supasate Choochaisri, Chalermek Intanagonwiwat

Logic macroprogramming paradigms for wireless sensor networks (WSNs) are rule-based abstractions for programming a network as a whole. Programmers only focus on the main objective of the network rather than the low-level implementation details on each nod... see more

Pornchai Bumroongsri, Soorathep Kheawhom

In this paper, an off-line synthesis approach to robust constrained model predictive control for uncertain polytopic discrete-time systems is presented. Most of the computational burdens are moved off-line by pre-computing a sequence of state feedback con... see more

Yu Chen, George Lopp, Reynaldo Roque

A composite specimen interface-cracking (CSIC) test was developed to evaluate the effect of the characteristics of the interface between asphalt layers on resistance to top-down and reflective cracking. The system involves repeated tensile loading and mon... see more

Cristian S Clopotel, Hussain U. Bahia

Elastic Recovery (ER) is used by many highway agencies for modified bitumen grading specifications. The current ASTM/AASHTO standards for ER testing utilize the ductility bath as the measurement apparatus. A new procedure for measuring the elastic recover... see more

One of high efficient ways to reuse the recycled construction and demolition waste (CDW) is to consider it as a road base material. The recycled CDW however is mainly a mix of recycled masonry and concrete with a wide variation in composition. This result... see more

On runway pavements in Japan, grooves for transverse directions should be set on most of runway area. The aim of runway grooving is to drain rain water on surface, which prevents from hydroplaning. According to the specification of Japan, two months as a ... see more
