While Portland cement concrete (PCC) overlay has been increasingly used as a rehabilitation technique for deteriorated PCC pavements in the last decade, reflective cracking places a major limit on its durability performance. The use of ultra ductile concrete named Engineered Cementitious Composite (ECC) should arrest such failure mode and greatly enhance the long term performance of the overlai...

Nonlinearities in MEMS silicon resonators are caused by different effects. Depending on the resonator layout, different nonlinearities may be ominant in the resonator response. Based on experimental results, a modelling approach is proposed to arrive at a nonlinear dynamic model that otentially captures the observed behaviour. Apart from the model, consisting of a mechanical and an electrical (...

CRACKING THE SCLEROTIC BONE RIM COMPARED TO REAMING +*Elmengaard, B; **Bechtold, JE; *Baas, J; Jakobsen, T; *Søballe, K +*Department of Orthopaedic Surgery, University of Aarhus, Denmark [email protected] INTRODUCTION Revision hip replacement implants have poorer clinical outcome than primary implants. The fixation of the implants is often compromised by the formation of an endosteal scleroti...

Sorbitan sesquioleate is a mixture of monoesters and diesters of oleic acid and hexitol anhydrides derived from sorbitol (1). It is an emulsifying agent that is widely used in cosmetic formulations and pharmaceutical products, including topical steroids (2). In the fragrance mix I obtained from Hermal (Reinbek, Germany), one of the main manufacturers of patch test ingredients, sorbitan sesquiol...

Te fl on and tetrafluoroethylene photopolymers, on py rolysis in a vacuum at 423.5 0 to 513.00 C, yield almost J 00 perce nt of monom er. The rate of formation of monomer at a n.,· given tem perat ure fo llows a first-order react ion and is independent of t he method of prepa ration of poly mer or its initial average molecu lar weight. The activation energy was determined by a pressure method a...

This project examines the nature of password cracking and modern applications. Several applications for different platforms are studied. Different methods of cracking are explained, including dictionary attack, brute force, and rainbow tables. Password cracking across different mediums is examined. Hashing and how it affects password cracking is discussed. An implementation of two hash-based pa...

current article describes application of zeolites in fluid catalytic cracking (fcc). the use of several zeolitic additives for the production light olefins and reduction of pollutants is described. application of zeolites as fluid catalytic cracking (fcc) catalysts and additives due to the presence of active acid sites in the zeolite framework  increase the formation of desired cracking product...

Variant Stochastic cracking is a significantly more resilient approach to adaptive indexing. It showed [1]that Stochastic cracking uses each query as a hint on how to reorganize data, but not blindly so; it gains resilience and avoids performance bottlenecks by deliberately applying certain arbitrary choices in its decision making. Therefore bring, adaptive indexing forward to a mature formulat...

_____________________________________________________________ Different catalysts based on Y-zeolite, ZSM-5 and amorphous kaolin were prepared and characterized. The catalytic cracking of 1,3,5-triisopropylbenzene (1,3,5-TIPB), 1,4diisopropylbenzene (1,4-DIPB) and n-dodecane were used to investigate the effect of catalyst nature on the catalytic performance. Cracking the largest molecule (1,3,5...
