Various methods of toughening the bonding between the interleaf and laminate glass fiber reinforced polymer (GFRP) have been developed due to the increasing applications in industries. A polystyrene (PS) additive modified epoxy is used to improve the diffusion and precipitation region between polysulfone (PSU) interleaf and epoxy due to its influence on the curing kinetics without changing glas...

We consider the problem of minimizing the cycle time of a given pipelined circuit. Existing approaches are suboptimal since they do not consider the possibility of simultaneously resynthesizing the combinational logic and moving the latches using retiming. In 1101 the idea of simultaneous retiming and resynthesis was introduced. We use the concepts presented there to optimize a pipelined circui...

Testability measures are controllability and observability. Controllability guides the test generation algorithms while setting a value to primary input (PI) in line justification problem. When more than one path are available for error propagation Observability finds which path is to be select. This paper describes controllability functions (CC0, CC1) and observability function (ob) for combin...

Combinational simplification techniques have proved their usefulness in both industrial and academic model checkers. Several combinational simplification algorithms have been proposed in the past that vary in efficiency and effectiveness. In this paper, we report our experience with three algorithms that fall in the combinational equivalence checking (sweeping) category. We propose an improveme...

15. Supplementary Notes Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. 16. Abstract Curing has substantial effects on the long-term performance of Portland cement concrete (PCC) pavement. TxDOT requires two applications of curing compounds, with a maximum 180 sf/gal per each application. However, no compliance testing is cond...

AIM The aim of this study was to evaluate the heat generation of three different types of light curing units. METHODS AND MATERIALS Temperature increases were recorded from a distance of 1 mm from a thermocouple to the tip of three different types of light curing units including one quartz-tungsten halogen (QTH), one plasma arc (PAC), and one light emitting diode (LED) unit. An experimental m...

In modern research, development of monomers that reduce shrinkage of composite materials remains an ongoing quest and perennial challenge. The purpose of this study, therefore, was to analyze the shrinkage behaviour of an innovative composite material for dental restorations based on a monomer with a new chemical formulation, known as silorane. To this end, shrinkage stress development during c...

Aim The aim of this study is to evaluate and to compare the effect of different light-curing modes and different liners on cuspal deflection in premolar teeth restored with bulk filled or incrementally filled composite measured at different time intervals. Materials and Methods The study was divided into two parts (Part 1-different curing modes, Part 2-different liner) each with sixty extract...

This paper reports the results of an experimental work conducted to investigate the effect of curing conditions on the compressive strength of self-compacting geopolymer concrete prepared by using fly ash as base material and combination of sodium hydroxide and sodium silicate as alkaline activator. The experiments were conducted by varying the curing time and curing temperature in the range of...
