Abstract:

Reuse of components as opposed to material recovery, recycling or disposal has been identified as one of the most efficient EOL strategies for products. The concept behind reuse is that some components and subassemblies have a design life that exceeds the life of the product itself. In order for reuse to be successfully implemented as an EOL strategy, a designer needs to incorporate into a product a philosophy of Design for Reuse (DfRe) at the early design stage. Reliable methods to assess the remaining life of used components based on a products usage life are also required. Furthermore, curr

Abstract:

Evaluation is the key to effective interface design. It becomes even more important when the interfaces are for cutting edge technology, in application areas that are new and with little prior design knowledge. Knowing how to evaluate new interfaces can decrease development effort and increase the returns on resources spent on formative evaluation. The problem is that there are few, if any, readily available evaluation tools for these new interfaces. This work focuses on the creation and testing of a new set of heuristics that are tailored to the large screen information exhibit (LSIE) system

This thesis describes the evaluation of several proposals suggested as replacements for the currenT Internet's TCPJIP protocol suite. The emphasis of this thesis is on how the proposals solve the current routing and addressing problems associated with the Internet. The addressing problem is found to be related to address space depletion, and the routing problem related to excessive routing costs. The evaluation is performed based on criteria selected for their applicability as future Internet design criteria. AIl the protocols are evaluated using the above-mentioned criteria.

Abstract:

Compression of coated pellets is a practical alternative to capsule filling. The current practice is to add cushioning agents to minimize the stress on the coated pellets. Cushioning agents however add bulkiness and reduce the overall drug loading capacity. In this study, we investigated the performance of compressed coated pellets with no cushioning agent to evaluate the feasibility of predicting the coat behaviour using thermo-mechanical and rheological analysis techniques. Different coating formulations were made of ethyl cellulose (EC) as a coating polymer and two different kinds of

The objective of the research presented in this thesis was to investigate the effects of wearout processes on the performance and reliability of CMOS bistable circuits. The main wearout process affecting reliability of submicron MOS devices was identified as hot-carrier stress (and the resulting degradation in circuit performance). The effect of hot-carrier degradation on the resolving time leading to metastability of the bistable circuits also have been investigated. Hot-carrier degradation was identified as a major reliability concern for CMOS bistable circuits designed using submicron techn

Abstract:

Many software systems fail as a direct consequence of errors in requirements analysis. Establishing formal metrics early in the design process, using attributes like critical parameters, enables designers to properly assess software success. While critical parameters alone do not have the potential to drive design, establishing requirements tied to critical parameters helps designers capture design objectives. For the design of interactive systems, the use of scenario-based approaches offers natural user centricity and facilitates knowledge reuse through the generation of claims. Unfortunately

Abstract:

Long-span bridges are flexible and therefore are sensitive to wind induced effects. One way to improve the stability of long span bridges against flutter is to use cross-sections that involve twin side-by-side decks. However, this can amplify responses due to vortex induced oscillations. Wind tunnel testing is a well-established practice to evaluate the stability of bridges against wind loads. In order to study the response of the prototype in laboratory, dynamic similarity requirements should be satisfied. One of the parameters that is normally violated in wind tunnel testing is Reynolds numb

Le travail présenté dans ce manuscrit concerne la fabrication de biomatériaux poreux à base d’acide polylactique pour les tissus conjonctifs et calcifiés en utilisant des procédés de chimie verte. Le but de cette thèse est de corréler l’influence de certains paramètres de procédés à la structure morphologique et les propriétés des mousses générées. Nous avons étudié, d’un côté, les effets de mélange d’acide hyaluronique et d’acides polylactiques afin d’améliorer les propriétés d’adhésion de ces biomatériaux. Nos résultats montrent bien une augmentation de l’énergie d’adhésion mais aussi une di

Abstract:

We investigate the ultraconnectivity condition on graphs, and provide further connections between critical and ultraconnected graphs in the positive definite partial matrix completion problem. We completely characterize when the join of graphs is ultraconnected, and prove that ultraconnectivity is preserved by Cartesian products. We completely characterize when adding a vertex to an ultraconnected graph preserves ultraconnectivity. We also derive bounds on the number of vertices which guarantee ultraconnectivity of certain classes of regular graphs. We give results from our exhaustive enumerat

Abstract:

Rate-induced transitions have recently emerged as an identifiable type of instability of attractors in nonautonomous dynamical systems. In most studies so far, these attractors can be associated with equilibria of an autonomous limiting system, but this is not necessarily the case. For a specific class of systems with a parameter shift between two autonomous systems, we consider how the breakdown of the quasistatic approximation for attractors can lead to rate-induced transitions, where nonautonomous instability can be characterised in terms of a critical rate of the parameter shift. We find a

Abstract:

Due to the airliners and aircraft operators pressure on reducing the operating costs, the diagnostic systems are included in aircraft, so that the wearness of single functional elements of other functional systems can be monitored. This monitoring can save money, that are usually spent on maintenance and especially, it leads to an increase of the overall safety of aircraft operations. The task of this work is to design a diagnostic system for small transport aircraft. For the right and proper design, is the correct understanding of the functions of each part on aircraft systems needed. The par
