Abstract:
From the ancient times, people used various kinds of natural material to build architecture. Because of the characteristics of natural materials, there are many limits to challenge the possibility of the architectural structure.After the fire of 1871 in Chicago, there were many incentives to convince Chicago architects to use steel as the material in grid structure buildings. For example, rising real estate prices, the advent of the safety elevator and availability of cost effective steel members. After that, grid structures play a very important role in modern architectural history. Now,

Abstract:
This dissertation is concerned with the behaviour of square-on-square double-layer space grids (DLSG's) and in particular their collapse mechanisms after initial buckling. A detailed review of the methods used for collapse analysis of these structures is conducted, which shows that their collapse can be of progressive nature. An outline of the remedies that have been suggested to make safe their collapse behaviour is given, and it traces the line for further study. The present investigation starts by describing the redundancy in these regular pin-jointed assemblies in terms of unit states of s

Abstract:
ABSTRACT Space marching methods are widely used to calculate steady supersonic internal and external flows in view of their superior efficiency as compared to time marching approaches. A very general space-marching procedure was proposed by Nakahashi and Saitoh in 1996. The method can be used with any explicit time-marching procedure, allows for embedded subsonic regions, and is well-suited for unstructured grids, enabling a maximum of geometric flexibility. The flow field is only updated in the so-called active domain. Once the residual has fallen below a preset tolerance, the active domain i

In the experimental study a mock-up of a realistic fuel bundle with five spacer grids of thin plate spring construction was investigated.

Five pressure taps were drilled in one of the rods, which could exchange position with other rods, in this way providing a large degree of freedom.

This project represents the search for an architecture within the physical, historical, and political situation that an existing city presents. Set within the physical bounds of Savannah, it builds upon an understanding of the city as a series of Utopian propositions existing subliminally and often incongruously. As such, the project concerns the making of public space--space to relieve the culturally disjointed condition of modern urban life by acting as a sort of stage for creative expression and collective improvisation.

This thesis presents a study on rotation in 2 dimensional and 3 dimensional discrete spaces. In computer science, using floating numbers is problematic due to computation errors. Thus we chose during this thesis to work only in discrete space. In the field of computer vision, the rotation is a transformation required for many applications. Using discretized Euclidean rotation gives bad results. Then, it is necessary to develop new rotation methods adapted to the discrete spaces. We mainly studied the hinge angles that represent the discontinuity of the rotation in the discrete space. Indeed, i

Tuberculosis (TB) has plagued humanity for centuries, and, despite being largely curable, it still claims thousands of lives daily. The causative agent, Mycobacterium tuberculosis (M. tb), shows resilience by evading immunological and antitubercular challenges. This is mainly due to its lipid-rich cell wall, whose main components are mycolic acids (MAs). MAs are long fatty acids with functional groups of precise stereochemistry. The MA chemical structure and composition balance in the cell wall modulates antigenicity, cell wall permeability, and virulence. MA chemical structure also steers MA

The continuing increase in the adoption and use of wireless technology aggravates the problem of spectrum scarcity due to the way we utilize the spectrum. The radio spectrum is a limited resource regulated by governmental agencies according to a fixed spectrum assignment policy. However, many studies show that this fixed radio frequency allocation leads to significant underutilization of the radio spectrum creating artificial scarcity, as most of the allocated spectrum is not used all of the time in every location.

The strategy reacts to social exclusion of inhabitants of the Cejl district. It supports employment and intends to build a dynamic public space, that is missing in the area. Social urbanism focuses on the interaction of inhabitants between each other and with the spaces, and creates conditions for new workplaces. The massive broken block gets the order. The park defines a system for future development and opens up new possibilities of usage. Thanks to its low cost construction, the park can work immediately. The order created by the park allows the future objects to emerge freely and spontaneo

Abstract:
This master thesis in media and communication studies explores the concept of the smart home, which by various industries within communication, information and energy business alongside property developers is expected to be the model for future living, housing and infrastructure development. Departing from a theoretical framework highlighting media and infrastructure as temporal and spatial phenomena, the analysis shows how the smart home arranges and manages both means of time and space due to its saturation of information technologies in the form of sensors, applications and data visualizati

Abstract:
The primary concern of this work is real-time fluid simulation on modern programmable graphics hardware. It starts by introducing fundamental fluid simulation principles with focus on Smoothed particle hydrodynamics technique. The following discussion then provides a brief introduction to OpenCL as well as contemporary GPU hardware and outlines their programming specifics in comparison with CPUs. Finally, the last two chapters of this work, detail the problem analysis and its implementation.

Abstract:
The vibration of and wave propagation in periodic cellular structures are analyzed. Cellular structures exhibit a number of desirable multifunctional properties, which make them attractive in a variety of engineering applications. These include ultra-light structures, thermal and acoustic insulators, and impact amelioration systems, among others. Cellular structures with deterministic architecture can be considered as example of periodic structures. Periodic structures feature unique wave propagation characteristics, whereby elastic waves propagate only in specific frequency bands, known as "p

Abstract:
This thesis evaluates the security of Supervisory Control and Data Acquisition (SCADA) systems, which are one of the key foundations of many critical infrastructures. Specifically, it examines one of the standardised SCADA protocols called the Distributed Network Protocol Version 3, which attempts to provide a security mechanism to ensure that messages transmitted between devices, are adequately secured from rogue applications. To achieve this, the thesis applies formal methods from theoretical computer science to formally analyse the correctness of the protocol.
