Abstract:

Dietary fiber is a component in the structure of plants which is an important aspect of diet and nutrition. The demand of fiber has increased significantly, as consumers recognize its health benefits such as reduction of risk of colon cancer, cholesterol lowering affect, regulating blood glucose levels and low calorie intake. Therefore food manufacturers pay more attention to develop new products containing high fiber content. Of all the categories of food products, bakery products are the most common fiber-enriched products. In this research two different wheat bran fibers (coarse and fine fi

Abstract:

Arising from the discussion about a sustainable development of the energy sector, more and more interest of different industrial branches (e.g. in the automotive field or by the energy supply companies) is actually directed to the use of fuel cells. They show high degrees of ef-ficiency, little pollution and the ability of combined heat and power generation, and moreover they are modularly built. As a fuel they need hydrogen, but the infrastructure of its supply is much worse than necessary. So, at least for a time of transition, hydrogen must be produced from hydrocarbon fuels.

Abstract:

Diagnosis and treatment of teeth with longitudinal fractures is challenging. Cracks are usually not visible radiographically; they require a thorough evaluation to aid in diagnosis. Patients may be asymptomatic, demanding the dentist rely on clinical findings to make a diagnosis. Early diagnosis of the presence and extent of a crack is essential for the successful management of a cracked tooth. There is limited information in the literature regarding the prevalence or predictive factors of cracks extending into the pulp chamber of teeth.

Abstract:

<p>We present the noncommutative version of the Polly Cracker cryptosystem, which is more promising than the commutative version. This is partly because many of the ideals in a free (noncommutative) algebra have an infinite Gröbner basis, which can be used as the public key in the cryptosystem. We start with a short brief of the commutative case which ends with the conclusion that the existence of "intelligent" linear algebra attacks ensures that such cryptosystems are left insecure. Further, we see that it is hard to prove that noncommutative ideals have an infinite reduced Gröbner basis fo

Abstract:

We develop a public key cryptosystem whose security is based on the intractability of the ideal membership problem for a noncommutative algebra over a finite field. We show that this system, which is the noncommutative analogue of the Polly Cracker cryptosystem, is more secure than the commutative version. This is due to the fact that there are a number of ideals of noncommutative algebras (over finite fields) that have infinite reduced Groebner bases, and can be used to generate a public key. We present classes of such ideals and prove that they do not have a finite Groebner basis under any

Most of the concrete buttress dams in Sweden were built from the 1950s till the1980s based on the traditional method of analyses. Those structures are reinforced and heavy in structure. Their height to thickness ratio being large makes them prone to crack during their lifespan. The presence of these cracks make the reinforcements used in the buttress dam susceptible to corrosion due to the water entering through the cracked areas. Therefore, studying the effect of cracks and corrosion regarding the safety of dams is important and should be carried out before the dams fail to function. However,

As a consequence of metal fatigue, cracks can develop and grow in operational aircraft. Periodic inspections must be made in order to detect and repair them before they reach a dangerous length. Cracks which grow from holes are a significant problem for aircraft since the wings and fuselage can contain many thousands of fasteners, or rivets. Since it is impractical to remove them all, inspection must be made with them installed.

Abstract:

Presently, durability design of reinforced concrete structures is dealt with in a purely deterministic way and deterioration models have not been developed to their full potential. In particular, researchers who have investigated corrosion and the models currently used to predict the response of concrete, have often overlooked the effect of cracking. Cracks in concrete generally interconnect flow paths and increase the influx of water or aggressive chemical ions into the concrete, facilitating its deterioration. The present research program was undertaken primarily to study the effect o

Abstract:

Although a great deal of work in investigating the possibility of using linear vibration techniques to detect damage in bridges has been carried out over the past 25 years, there are still some major concerns, such as poor sensitivity of modal parameters to damage, requirement of baseline data, need of measuring excitation force as well as environmental effects. Nonlinearity in the vibration characteristics when the structure is damaged further complicates the problem and causes doubts on the feasibility of applying these techniques on actual structures. Understanding of the nonlinear behaviou

Abstract:

This thesis deals with three inter-related topics. The first topic is concerned with the solution of a cracked transversely isotropic—orthotrOpic composite laminate of finite thickness. The transversely isotropic sublaminate which is sandwiched between orthotropic outer sublarninates contains a central crack or an array of periodically distributed cracks which are perpendicular to the interfaces between the two media. When the crack is wholly within the sublaminate, solutions are obtained for the stress intensity factors and the crack-induced interfacial stresses in three loading modes. When t
