Plastic is one of the most popular materials used in products, but it also leaves the earth to deal with a major environmental issue, namely plastic pollution. The oceans in particular are filled with plastic waste, which harms biodiversity and ecosystems. It also negatively impacts countries and their …

In this paper, we consider the optimal deployment of multiple assets in anti-submarine warfare (ASW) operations with time-dependent strategies. We model this as a zero-sum game that takes place over a finite time horizon. An agent, representing multiple assets, in an ASW operation, decides on the allocation …

Iatrogenesis is the doctrine that deals with the harmful effects of medical treatment. A substance that, for example, tackles the pathogen may also weaken the body. If it weakens the body and does not address the pathogen sufficiently, it may well be that the resistance of the body itself becomes insufficient …

In this thesis, we develop mathematical models for the optimal deployment of security forces addressing two main challenges: adaptive behavior of the adversary and uncertainty in the model. We address several security applications and model them as agent-intruder games. The agent represents the security …

There are a lot of problems associated with clayey soil. More geotechnical pathologies appeared as more developed project brighten up. The geotechnical engineers encounter problems with modelling the stiff clayey soil behaviour especially while using the classical methods for obtaining the input parameters …

Mild steel is relatively low-cost and easily accessible material to fabricate some structural members. It would be a significant advantage if seismic energy dissipaters that are used in structures constructed in the earthquake prone areas, could also be produced on site. In this paper, a promising seismic …

Normal is a concept that stems from two very interesting mathematical concepts: the normal distribution and the central limit theorem. People possess infinite numbers of properties. By far the most are unknown, they don’t matter to our reality. However, through our knowledge systems - perception and …

The authors consider the reality that endless economic growth on a finite planet is unsustainable, especially if society has exceeded ecological limits. The paper examines various aspects of society's endless growth predicament. It reviews the idea that there are 'limits to growth'; it then considers …

Laminated composites have important applications in modern aeronautical structures due to their extraordinary mechanical and environmental behaviour. Nevertheless, aircraft composite structures are highly vulnerable to impact damage, either by low-velocity sources during maintenance or high-velocity …

To obtain a unified framework for symmetric and asymmetric heterotic orbifold constructions we provide a systematic study of Narain compactifications orbifolded by finite order T -duality subgroups. We review the generalized vielbein that parametrizes the Narain moduli space (i.e. the metric, the B-field …
