This manuscript presents simulation results of energy dissipation in sub-threshold (sub-VT ) of various 16-bit adder structures. The architectures designed for the comparative experiments are, a bit-serial, an 8-bit digit-serial and a 16-bit parallel adder structures. The designs are synthesized in a 65 nm low-leakage high-threshold CMOS technology. The results show that an energy minimum operatin

This dissertation aims at showing that Chrétien de Troyes' Conte du Graal does not, as often affirmed, uphold traditional chivalrous values, but discloses a problematic ideology, mostly as a result of multiple interactions at the textual level. In order to examine ideology, Le Conte du Graal is analysed in the light of the poetics elaborated by Vincent Jouve in his Poétique des valeurs (2001). Fol

Calculations on a Homogeneous Charge Compression Ignition (HCCI) engine have been performed. Zero-dimensional models were used. The simplest model compressed the gas to auto-ignition, using temperature and pressure at a certain crank angle position obtained from engine experiments. It was found that calculations with good agreement could be accomplished, if using correct temperature, pressure and

This dissertation is about the way buildings archaeology approaches historical buildings. The aim is to show how buildings archaeology can be renewed and developed. The motivation is my belief that buildings archaeology does not fully utilize the potential of standing buildings as historical sources, which is mainly due to the traditional outlook on buildings as two-dimensional objects. When three

In this dissertation I have sought to test the possibility of recreating a detailed picture of an individual medieval person, tracing the Danish archbishop Absalon's own world of thought and action through those surviving sources that he has left behind. The sources are both written and material, and they include the cloister church in Sorø, the Havn Castle, the Medieval history Gesta Danorum, the

Debt is commonly used by firms as a way of financing. Factors driving stock return have been the subject of numerous studies. Investors are constantly seeking ways to better understand stock return, which is where financial statements may provide them with relevant information. The presented research paper focuses on explaining whether there is a significant relationship between stock return and l

Many anthropogenically-produced or beneficiated materials contained in “end-of-life” products retain a great proportion of the invested manufacturing work when discarded. Very few such materials are reconstituted and applied in new products at the same material inherent quality level as in their first lifetime – a process known as “closed-loop recycling”. In general, industrial society maintains a

The present study deals with different aspects of the mitsvat mezuzah in Rabbinic literature from the first to the sixteenth centuries, with some emphasis on the medieval sources. Through a charting of statements regarding the mezuzah as an object, and the mitsvat mezuzah and its fulfilment, an overview is given of the development of the mezuzah and the perception of it

In software engineering, the quality of software and in particular the software reliability has to be controlled and improved. Hence there is a need for measuring and controlling the number and appearance of software faults and failures. This thesis presents models for estimation of residual faults after inspections and a model for usage specifications which enables estimation of operational failu

One part of the objective is to analyze how different ventilation systems perform in practice when it comes to supplying and exhausting designed air flow in different outdoor and indoor conditions. The other part is to analyze the design criterias and the energy use of a variable air volume system based on controlled static pressure at the branch duct level and supplying outdoor air only. To inves

The topic of the thesis is control of Homogeneous Charge Compression Ignition (HCCI) engine dynamics. HCCI offers a potential to combine high efficiency with very low emissions. In order to fulfill the potential benefits, closed-loop control is needed. The thesis discusses sensors, feedback signals and actuators for closed-loop control of the HCCI combustion. Closed-loop control of the HCCI combu

Enterprise Systems are one of the most important developments in corporate information systems during the last decade. These integrated information systems are characterized by a number of features which include a very broad scope and functionality, as well as being generic, master data, and business-process orientated. Together, these features make Enterprise Systems unique vis-à-vis other inform

The study analyses various aspects of international economics related to foreign direct investment, trade and specialisation. These issues are considered in view of the increased internationalisation - through trade and foreign direct investment - in recent decades. Special interest is devoted to the effects of economic integration. Chapter two examines the importance of FDI and country capabiliti

Very little is known about a considerable part of all proteins and it is time consuming and expensive to study each individual protein to determine its function, structure and cellular role. Proteins retain structural, functional and sequential characteristics from ancestral proteins and hence two proteins that share a common ancestor, i.e. are homologs, will to some extent have similar sequen

In the present work a dynamic model library of components for process lines was developed. The analysis addressed characteristic aspects of liquid food process lines, and new models were developed for fluid transitions, dispersion, mixing zones and first-order chemical reactions in pipes and heat exchangers. The computational efficiency and accuracy of the models were analysed. It was demonstrated

Size, as expressed by molar mass, radius of gyration or hydrodynamic radius, for example, is a fundamental parameter of polymers in solution. Thus, there is a strong need for the characterisation of both the size and shape of polymers, particularly of those utilised in various industrial applications. In this thesis, a relatively novel technique, asymmetrical flow field-flow fractionation (flow FF

A new approach to the study of nanoparticle systems has been introduced. Nanoparticle systems in aqueous and organic solutions have been synthesized and studied by transmission electron microscopy. These systems include nanoparticles of gold, silver, palladium, ruthenium, and platinum which have been stabilized using various ligands. The particles were initially studied as deposited samples on ca
