Computational complexity

The phase-field method has become a robust tool to describe the complex crack nucleation and propagation in heterogeneous materials. In these materials, an interaction between bulk brittle damage and interfacial damage through the splitting the strain tensor into a bulk strain part and a jump strain part at the interfaces.

This paper proposes an efficient method to determine entire reducts of incomplete decision tables according to the relational database approach. In the complex case, this algorithm has exponential computational complexity. However, this algorithm has polynomial computational complexity in the different cases of databases.

Intrusion Detection (ID) is one of the active branches in network security research field. Many technologies, such as neural networks, fuzzy logic and genetic algorithms have been applied in intrusion detection and the results are varied. In this thesis, an Artificial Immune System (AIS) based intrusion detection is explored. AIS is a bio-inspired computing paradigm that has been applied in many different areas including intrusion detection.

The thesis is structured as follows: In Chapter 1, the scientific literature is summarized within the scope of this study. Chapter 2 provides a comprehensive overview of the principles of the applied computational approaches in this study. Chapter 3 identifies the important residues of the LsIA/α7 nAChR complex that affect the interactions between the toxin and the membrane protein due to C-terminal carboxylation of LsIA. The effects of C-terminal modification of LsIA on interactions with α3β2 nAChR, involved in cardiovascular diseases, were also investigated in Chapter 4.

We have investigated the consequences of introducing a bisecting GlcNAc moiety into biantennary N-glycans. Computational analysis of glycan conformation with pro-longed simulation periods in vacuo and in a solvent box revealed two main effects: backfolding of thea1–6 arm and stacking of the bisectingGlcNAc and the neighboring Man/ GlcNAc residues of both antennae.Chemoenzymatic syn-thesis produced the bisecting biantennary decasaccharide N-glycan and itsa2–3(6)-sialylated variants.

A versatile software tool,virtualmslab, is presented that can perform advanced complex virtual proteomic experiments with mass spectrometric analyses to assist in the characterization of proteins. The virtual experimen-tal results allow rapid, flexible and convenient exploration of sample prepar-ation strategies and are used to generate MS reference databases that can be matched with the real MS data obtained from the equivalent real experi-ments.

The direct conversion of plant cell wall polysaccharides into soluble sugars is one of the most important reactions on earth, and is performed by cer-tain microorganisms such as Clostridium thermocellum(Ct). These organ-isms produce extracellular multi-subunit complexes (i.e. cellulosomes) comprising a consortium of enzymes, which contain noncatalytic carbohy-drate-binding modules (CBM) that increase the activity of the catalytic module.
