In support of the initiatives for implementing the new MechanisticEmpirical Pavement Design Guide (MEPDG) in Iowa, a preliminary sensitivity study was undertaken to assess the comparative effect of design input parameters pertaining to material properties, traffic and climate on performance of two existing flexible pavements in Iowa with relatively thick Asphalt Concrete (AC) layers. A total of...

because thin plate reinforced concrete members such as walls and slabs are greatly influenced by the drying shrinkage, cracks can occur in these members due to the restraint of the volume change caused by drying shrinkage. therefore, the control of cracking due to drying shrinkage is very important in building construction that the thin plate members are frequently used. however, few researches...

Cline, J. A. and Trought, M. 2007. Effect of gibberellic acid on fruit cracking and quality of Bing and Sam sweet cherries. Can. J. Plant Sci. 87: 545–550. Rain-induced cracking of sweet cherries (Prunus avium L.) is a major problem in many cherry growing regions throughout the world. One method to reduce cracking is to grow cracking resistant cultivars; however, no completely effective control...

In the purely theoretical approach of pavement design, percentage fatigue cracking is related to damage in a probabilistic manner according to the Miner’s law. Two methods that are currently widely in use are based on assumptions of damage distribution. One method assumes fatigue damage being normally distributed, while the other one assumes fatigue damage being lognormally distributed. Since m...

This paper talks about the self-oraganized index maintainance approach of database cracking. It provides fundamental knowledge as well as the description of a basic implementation of database cracking. Alongside multiple cracking algorithms, the implementation also contains the code of a cracking index. By combining these two features the implementation allows the execution of range queries on ...

In order to explore the cracking behavior of opening-mode reflective cracks in asphalt overlays, we carry out three-point bending test composite beams with cement overlay layer. We quantitatively evaluate damage based on acoustic emission (AE) characteristic parameters.Firstly, dynamically monitor process using AE technique, then, analyze horizontal strain through open source digital imaging so...

With the rapid development of internet technologies, social networks, and other related areas, user authentication becomes more and more important to protect the data of the users. Password authentication is one of the widely used methods to achieve authentication for legal users and defense against intruders. There have been many password cracking methods developed during the past years, and p...

A study in the growth of GaN,P, _s epilayers by chemical beam epitaxy using tertiarybutylphosphine (TBP), ammonia (NH3), and elemental Ga or triethylgallium is reported. Monitoring reflection high-energy/ electron diffraction (RHEED) intensity oscillations, we observe that both group-IIIand group-V-induced incorporation rates are increased when NH3 is introduced into a single cracker with TBP. ...

Name obfuscation is a software protection technique, which renames identifiers in a given program, to protect the program from illegal cracking. The conventional methods replace names appearing in the declaration part with the meaningless ones. Therefore, the methods cannot be used to obfuscate names declared in system libraries, since changing such system-defined names significantly deteriorat...

in this work, ferric coagulation and acid cracking as olive mill wastewater (omw) pretreatments during photocatalysis process were compared in batch recirculation reactor. as ferric ions influence, ferric coagulation has preference over acid cracking. ferric ions influence on intensification of penolic components absorption on tio2 surfacein initial and oxidize organic pollutant during photocat...
