Abstract:

Branching in poly(methyl methacrylate) (PMMA) is produced by incorporating a pre-prepared polymeric chain transfer agent (PCTA) into a single stage radical polymerisation. Samples of PCTA having a range of transfer functionalities and molar masses were synthesised by modifying a methacrylate-based copolymer. Control of branching in PMMA has been studied as a function of transfer functionality and molar mass in the PCT A and a function of MMA and initiator concentrations in the MMA polymerisation. The branched samples of PMMA have been characterised by size exclusion chromatography (SEC) with m

Abstract:

18-methyl eicosanoic acid (18-MEA), which is a branched fatty acid, is found at the outermost surface of mammalian hair with other straight-chain fatty acids such as palmitic acid and stearic acid. However, the precise role of 18-MEA is not yet completely understood. 18-MEA on Cadmium chloride subphase forms curvature at the water/air interface, leading to the formation of 3D-domains that can be easily transferred into solid support allowing to create complex and multi-functional structures. This project investigates if a non-toxic subphase would also lead to the formation of 3D-domains or if

Abstract:

Type I modular polyketide synthases (PKSs) are giant multi-functional enzymes that catalyse the assembly of a range of bioactive natural products. The bacillaene synthase (PksX) from Bacillus subtilis is a member of the trans-A T PKS family and is responsible for the biosynthesis of the broad-spectrum antibiotic bacillaene. As in other trans-A T synthases the bacillaene system employs a five enzyme "RCS cassette" to introduce a distinctive ft-methyl branch into the final functional product. In this thesis I describe the structural and functional characterisation of three of the bacillaene synt

Abstract:

We introduce a very simple but efficient idea for branch & bound (B&B) algorithms in global optimization (GO). As input for our generic algorithm, we need an upper bound algorithm for the GO maximization problem and a branching rule. The latter reduces the problem into several smaller subproblems of the same type. The new B&B approach delivers one global optimizer or, if stopped before finished, improved upper and lower bounds for the problem. Its main difference to commonly used B&B techniques is its ability to approximate the problem from above and from below while traversing the problem tre

Abstract:

In this article a new branch & bound method is described. It uses an artificial target to improve its bounding capabilities. Therefore the new approach is faster compared to the classical one. It is applied to the stochastic problem of optimal scenario tree reduction. The aspects of global optimization are emphasized here. All necessary components for that problem are developed and some experimental results underline the benefits of the new approach.

Abstract:

Finding a way to automate the generation of test data is a crucial aspect of software testing. Testing comprises 50% of all software development costs [Korel90]. Finding a way to automate testing would greatly reduce cost and labor involved in the task of software testing. One of the ways to automate software testing is to automate the generation of test data inputs. For example, in statement coverage, creating test cases that will cover all of the conditions required when testing that program would be costly and time-consuming if undertaken manually. Therefore, a way must be found that allows

Abstract:

As structure and size of electric power distribution systems are getting more complex, distribution automation schemes become more attractive. One of the features that is desirable in an automated system is feeder reconfiguration for loss reduction. Loss reduction can make considerable savings for a utility and results in released system capacity. There is also improved voltage regulation in the system as a result of reduced feeder voltage drop. In this thesis, multi branch exchange algorithm is introduced to solve the network reconfiguration for loss reduction problem. The proposed technique

Abstract:

Resource Leveling Problem (RLP) aims to minimize undesired fluctuations in resource distribution curves which cause several practical problems. Many studies conclude that commercial project management software packages can not effectively deal with RLP. In this study a branch and bound algorithm is presented for solving RLP for single and multi resource, small size networks. The algorithm adopts a depth-first strategy and stores start times of non-critical activities in the nodes of the search tree. Optimal resource distributions for 4 different types of resource leveling metrics can be obtain

Abstract:

Lattice basis reduction is a powerful tool for solving complex problems both in pure mathematics and practical applications. In this thesis, we use lattice basis reduction as a preconditioning technique to accelerate the real relaxation based branch and bound (RRBB) method for solving integer least squares (ILS) problems. We give theoretical arguments and simulation results to show that applying lattice preconditioning to the RRBB method can greatly reduce the size of the RRBB tree for ordinary ILS problems, making the method more efficient. We then propose new reduction strategies, which are

Each car is assigned an individual relocation utility. The objective is to find shuttle tours that maximise in a given time the relocation utility while balancing the distribution of the cars.

Abstract:

The time/cost trade-off models in project management aim to compress the project completion time by accelerating the activity durations at an expense of additional resources. The budget problem in discrete time/cost trade-off scheduling selects the time/cost mode -among the discrete set of specified modes- for each activity so as to minimize the project completion time without exceeding the available budget. There may be alternative modes that solve the budget problem optimally, however each solution may have a different total cost value. In this study we aim to find the minimum cost solu

Abstract:

Polymer chain microstructure, including characteristics such as molecular weight and branch length, can impact the end-use properties of the polymer. The assumptions contained in deterministic models prevent examination of the structure of individual polymer chains, so removal of these assumptions is necessary to gain insight into molecular-level mechanisms that determine chain microstructure. The work presented here uses a combination of stochastic and deterministic models to examine two significant mechanistic issues in free radical polymerization. The zero-one assumption concerning the n

Abstract:

La gestion prévisionnelle des emplois et des compétences est une locution appartenant au vocabulaire gestionnaire ce qui lui confère une dimension organisationnelle indéniable et originelle. En droit la notion bénéficie depuis son apparition dans le Code du travail d'une indéniable publicité bien qu'elle préexistait à cette juridification. Elle garde malgré cela une certaine dose de mystère qui tient en partie aux relations qu'elle a longtemps entretenu avec les licenciements pour motif économique, à la pluralité des thématiques qui la composent ainsi qu'aux évolutions constantes de son régime

Abstract:

Typiquement présent dans les domaines de la logistique et des télécommunications, le problème de synthèse de réseau multi-flot à charge fixe reste difficile, en particulier dans des contextes à grande échelle. Dans ce cas, la capacité à produire des solutions de bonne qualité dans un temps de calcul raisonnable repose sur la disponibilité d'algorithmes efficaces. En ce sens, cette thèse propose des approches lagrangiennes capables de fournir des bornes relativement proches de l'optimal pour des instances de grande taille. L'efficacité des méthodes dépend de l'algorithme appliqué pour résoudre
