Abstract:

The Reactive Atom Plasma® (RAP) process is a plasma chemical etching process. RAP was developed at RAPT Industries as a process for removing subsurface damage from silicon carbide optics. The process is being investigated at Cranfield University as a novel method for the fine surface correction of large optics, with the aim of shortening the manufacturing period of the next generation of large telescopes. RAP offers material removal rates that are up to 10 times higher than those of ion beam figuring, the current state-of-the-art technique and the convenience in that it can be operated at atmo

Abstract:

The recycled asphalt pavement (RAP) extracted from recovery distresses in highways does not receive the attention and importance it deserves in Brazil. The reuse of this material, which presents as good properties as the virgin aggregate, when applied correctly in the composition of new pavement layers or rehabilitations, is a widely used in European and United States. Besides solving the environmental liabilities of pavement, the reuse of milled material in asphalt mixtures is a sustainable alternative, which decreases consumption of asphalt and virgin aggregate, milled material transportatio

Full text

Abstract:

Use of high percentage of Reclaimed Asphalt Pavement (RAP) material in Hot Mix Asphalt is one of the several sustainable construction alternatives being considered by many Departments of Transportation (DOT). Use of RAP in HMA helps in reducing the consumption of virgin aggregates and binder and construction cost and conserving energy. Although most of the US state agencies allow the use of 30% or more RAP in the design of Hot Mix Asphalt (HMA), the current average RAP usage is only about 10 to 20%. This is because of the uncertainty about the performance of HMA mixes with a high RAP content.

Attualmente i quantitativi di RAP comunemente utilizzati sono limitati data la mancanza di esperienza e di prove scientifiche che dimostrino la possibilità di includere fresato senza penalizzare le prestazioni della pavimentazione.

Abstract:

The objective of this research is to examine the effects that different methods of RAP stockpile fractionation have on the volumetric mix design properties for high-RAP content surface mixes, with the goal of meeting all specified criteria for standard HMA mix designs. The processing of RAP materials results in the degradation of the aggregate structure of the original pavement. The increased presence of fine RAP materials in the stockpile can be attributed to the amount of crushing done on the RAP millings.

Abstract:

The alkali-aggregate reaction (AAR) is a pathological manifestation that occurs in concrete structures and has concerned engineers and users of construction for decades, throughout the world. Basically, it is a chemical reaction resulting from the interaction between alkalis released from cement and some silicates in the reactive aggregates. Aggregates have been studied and there are many disagreements as to the involvement of the granitic aggregates in the AAR.

Abstract:

Este trabalho tem como objetivo principal a otimização dos protótipos fabricados pelo processo FDM (Fused Deposition Modeling) em procedimento baseado na análise do comportamento estrutural dos protótipos variando as estratégias de preenchimento das camadas. Para atingir tal objetivo, corpos de prova com diferentes orientações de preenchimento foram ensaiados experimentalmente e os resultados foram verificados em análise estrutural por elementos finitos. Foram verificados o caráter ortotrópico do material do protótipo e a validade do uso da Teoria Clássica dos Laminados na simulação de seu com

L'argomento della tesi di dottorato è la realizzazione di strati ultra-sottili di porfirine su substrato cristallino mediante evaporazione in Ultra Alto Vuoto (UHV), e il loro studio con una particolare tecnica ottica, la Spettroscopia di Riflettanza Anisotropa (RAS: Reflectance Anisotropy Spectroscopy), che ne permette la caratterizzazione in situ e in tempo reale. Il lavoro sperimentale ha riguardato dapprima il completo allestimento della camera UHV per la crescita degli strati organici, poi il raggiungimento delle condizioni necessarie alla deposizione, infine lo studio mediante RAS dei l

Abstract:

Syftet: Syftet med denna studie är att kartlägga belastningsergonomiska risker i ett framtida internt logistikflöde, samt att ge förslag på hur dessa risker kan undvikas genom tillämpning av LEAN metodik och en ny logistiklösning. Följande frågeställningar har ställts för att identifiera orsaker till problem och förbättringsmöjligheter: 1) Vilka arbetsmoment i det studerade logistikflödet leder till ergonomiska risker? 2) Hur kan fallstudieföretaget införa LEAN metodik för att uppnå bättre ergonomi vid materialhantering? 3) Hur kan en ny generell och mer ergonomisk logistiklösning fö
