Abstract:

The continuous research of lightening mechanical and aeronautical structures is leading to the adoption of innovative materials and structure designs. and this development has to be necessarily followed by research in optimising structural health monitoring techniques. The set up of a reliable and quick monitoring technique. together with the enhancement of the mechanical performances of structures, is the tUl1ung point to the usage of even lighter and longer-lifed structures. Being impossible to build up a monolithic structure, it is common sense to understand that the most critical part of a

Abstract:

In response surface methodology, the central composite design is the most popular choice for fitting a second order model. The choice of the distance for the axial runs, alpha, in a central composite design is very crucial to the performance of the design. In the literature, there are plenty of discussions and recommendations for the choice of alpha, among which a rotatable alpha and an orthogonal blocking alpha receive the greatest attention. Box and Hunter (1957) discuss and calculate the values for alpha that achieve rotatability, which is a way to stabilize prediction variance of the desig

Abstract:

Two distinct techniques for “optimum” fibre spreading of 2400 Tex E-glass and 12K carbon fibre bundles were designed and developed in this research project. These techniques enabled increases in fibre bundle width of 956% and 1121% for E-glass and carbon fibre bundles respectively. These values surpass anything reported in the literature. Tensile testing was conducted on dry fibre bundles in the as-received and spread state. A reduction in the tensile failure stress and Weibull survival probability was observed with an increase in gauge length. The effect of spreading was determined to be stat

Abstract:

In the aerospace, automotive, printing, and sports industries, the development of hybrid Carbon Fiber Reinforced Polymer (CFRP)-metal components is becoming increasingly important. The coupling of metal with CFRP in axial symmetric components results in reduced production costs and increased mechanical properties such as bending, torsional stiffness, mass reduction, damping, and critical speed compared to the single material-built ones. In this thesis, thanks to a novel methodology involving a rubbery/viscoelastic interface layer, several hybrid aluminum-CFRP prototype tubes were produced. B

In the modern built environment, building construction and demolition consume a large amount of energy and emits greenhouse gasses due to widely used conventional construction materials such as reinforced and composite concrete.

Abstract:

In many industrial experiments, completely randomized designs (CRDs) are impractical due to restrictions on randomization, or the existence of one or more hard-to-change factors. Under these situations, split-plot experiments are more realistic. The two separate randomizations in split-plot experiments lead to different error structure from in CRDs, and hence this affects not only response modeling but also the choice of design. In this dissertation, two graphical tools, three-dimensional variance dispersion graphs (3-D VDGs) and fractions of design space (FDS) plots are adapted for split-plot

The objective of the research presented in this thesis was to study and optimize the transverse deck reinforcement for a skewed concrete bridge deck supported by Hybrid Composite Beams (HCB\'s). An HCB consists of a Glass Fiber Reinforced Polymer outer shell, a concrete arch, and high strength seven wire steel strands running along the bottom to tie the ends of the concrete arch together. The remaining space within the shell is filled with foam. The concrete arch does not need to be cast until the beam is in place, making the HCB very light during shipping.

Abstract:

Practical restrictions on randomization are commonplace in industrial experiments due to the presence of hard-to-change or costly-to-change factors. Employing a split-plot design structure minimizes the number of required experimental settings for the hard-to-change factors. In this research, we propose classes of equivalent estimation second-order response surface split-plot designs for which the ordinary least squares estimates of the model are equivalent to the generalized least squares estimates. Designs that possess the equivalence property enjoy the advantages of best linear unbiased

As the fresh properties of SCC are quite important, mix design of a SCC is performed by considering various workability related fresh properties. Therefore, a well designed SCC should satisfy all requirements of a hardened concrete, besides its superior workability properties. The aim of this r

Abstract:

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior<br>Seaweed japonica saccharine, popularly known as "Kombu" is a food rich in protein, fiber and micronutrients. This algae has antioxidant properties, anti-viral, anti-tumor, anti-inflammatory and hypoglycemic. Quinoa (Chenopodium quinoa Willd) is considered a pseudocereal whose main characteristic is the quality of its protein and is recognized by the World Health Organization (WHO) as an ideal food for its nutritional composition is higher than most cereals. The addition of these two ingredients in salt cereal bar formulation can ad

Abstract:

Existe um número muito limitado de estudos referentes à produção de componentes antimicrobianos ou bacteriocinas produzidas por espécies de bifidobactérias. Nesse âmbito, o objetivo deste trabalho foi avaliar a produção de bifidobacteriocina em leite desnatado (LD). Para tanto, o estudo foi dividido em três etapas. A primeira etapa constituiu na preparação dos meios de cultura Man, Rogosa e Sharpe (MRS), Bifidus Selective Medium (BSM) e LD suplementado com 1% (p/v) de Tween 80 (T80), Inulina (I) ou Extrato de levedura (YE). Nesta etapa, os processos fermentativos foram conduzidos em shaker, na

Abstract:

The present study was aimed to address critical aspects related to the development of fresh-blended strawberry purees. The main focus was to evaluate and determine the effects of wounding intensity on respiration rate and biologically active compounds (Experiment 2.1), to survey most important strawberry cultivars grown in Italy for fresh-blended purees (Experiment 2.2), optimize the blending conditions (time and temperatures) (Experiment 2.3), and evaluate and compare packaging conditions using two different plastic materials under active and passive modified atmosphere conditions (Experiment

Abstract:

Cellulose nanocrystals (CNCs) are frequently prepared by sulfuric acid hydrolysis of a purified cellulose starting material. CNC yields, however, are generally low, often below 20%. This study employs response surface methodology to optimize the hydrolysis conditions for maximum CNC yield. Two experimental designs were tested and compared: the central composite design (CCD) and the Box–Behnken design (BBD). The three factors for the experimental design were acid concentration, hydrolysis temperature, and hydrolysis time. The responses quantified were CNC yield, sulfate group density, ζ-potent

Abstract:

Os pré-moldados de gesso são largamente utilizados na construção civil para o acabamento de interiores, devido a propriedades acústica, térmica, elétrica e, principalmente, por ser um produto de custo relativamente baixo. No Pólo Gesseiro Pernambucano, localizado na Região de Araripe, semi-árido nordestino, alcança-se anualmente 90 % da produção brasileira de gipsita O H 2 CaSO 2 4 , gesso O H 5 , 0 CaSO 2 4 e seus derivados, estimada em cerca de 2 milhões de toneladas. Existem hoje no Pólo Gesseiro mais de 150 fábricas de pré-moldados e os produtos principais são as placas e os blocos de gess
