The last century has been a turbulent period in Cambodia, yet in the recent decades it has emerged from conflicts and humanitarian crises and become one of the world’s fastest-growing economies. This transformation was enabled in large part by foreign aid (ODA) and foreign direct investment (FDI). This thesis analyses the mechanisms by which ODA and FDI influenced the economy individually and in c

Sustainability transition research investigates why the necessary change towards more sustainable patterns of consumption and production has not yet been achieved and how it can be accelerated. Taking into account the complexity of the globalised dynamics underlying today's sustainability challenges, it has been suggested that the existence of global regimes limits the possibilities for change

How far back in time can we trace fire use in the human story? The archaeological data has demonstrated inconsistency when it comes to answering that question. Incontrovertible remains after hearths are scarce especially before 100,000 years BP. One of the reasons are that remains after temporary hearths doesn’t preserve well in the archaeological record in comparison with for example, stone tools

Traditional risk assessment frameworks have been focused primarily on the factors of likelihood and impact, utilizing either a numerical (e.g. 1 to 5) or qualitative (e.g.low,medium, high) rating scale, resulting in the traditional two dimensional framework. The challenge of this model is that the focus is too narrow to eectively assess constantly changing risk environments and fails to dierentiat

We simulate the velocities of formed Black Holes to determine the fraction of retained Black Holes in 152 Globular Clusters. The model we used for the escape velocity is from Plummer. The scenarios of the natal kick are Neutronstar like kicks and momentum conserving kicks. We also consider the binary fraction which affect the retention of Black Holes. A typical Globular Cluster retains 0 or 102 BlThe Black Hole are popular objects in astronomy, a lot of scientists want to study their formation and evolution. Most astronomers agree with that there is a super massive black hole in the center of our galaxy. Also, some previous observations show that at least some clusters have black holes. As we all known, a typical black hole is formed by a core-collapse supernova of a massive star. The core

We describe and compare how methods based on the classicalRice’s formula for the expected number, and higher moments, of level crossingsby a Gaussian process stand up to contemporary numerical methods toaccurately deal with crossing related characteristics of the sample paths.We illustrate the relative merits in accuracy and computing time of the Ricemoment methods and the exact numerical method, We describe and compare how methods based on the classical Rice’s formula for the expected number, and higher moments, of level crossings by a Gaussian process stand up to contemporary numerical methods to accurately deal with crossing related characteristics of the sample paths.We illustrate the relative merits in accuracy and computing time of the Rice moment methods and the exact numerical meth

Choir singing has been suspended in many countries during the Covid-19 pandemic due to incidental reports of disease transmission (Hamner et al. Citation2020). The mode of transmission has been attributed to exhaled droplets, but with the exception of a study on tuberculosis from 1968, there is presently almost no scientific evidence of increased particle emissions from singing (Loudon and RobertsChoir singing has been suspended in many countriesduring the Covid-19 pandemic due to incidental reportsof disease transmission.

Popular Abstract in English Imagine a solar powered flash light. Each photon absorbed by the flash light’s solar cell creates electric energy and the flash light’s light source converts the electrical energy again into photons. The purpose of such a device may be questionable, because you would be surprised if it would create more light than what it absorbs. However, under certain conditions it isIn this thesis the luminescence properties of highly doped semiconductors are studied with focus on degenerately n-doped InP. It is demonstrated how photoluminescence measurements on degenerately doped semiconductors allow an estimation of the doping concentration without need for electrical contacts. The degenerate doping can furthermore reveal the conduction band structure for energies higher th

This study measures the effect of competition on leverage using unbalanced panel data from 4,957 US listed firms within 8 industries. To address the issues associated with concentration indexes, we contribute to the literature by using a new measure of competition – the Boone indicator which is based on efficiency. Initially results indicate a positive (negative) effect of competition (concentrati

The rapid globalization has led to a rise in the number of multinational corporations. One common objective among these corporations when expanding to other developed markets is to access intangible resources such as knowledge. Through the acquisition of knowledge, corporations can strengthen their strategic position and improve their competitiveness. When operating across national borders, variou

This project aims to highlight the manufacturer as an important asset in product development. In order to design a product, it is necessary, especially for industrial designers to have good knowledge of the manufacturing technologies that are available and to have knowledge of the working environments in which our ideas are put into practice. Increased cooperation between local actors opens opport

Presently the telecom industry is going through a massive shift in technology. In the business to business environment regarding delivery and service of fixed telephony, the traditional circuit-switched PBX (private branch exchange) technology is successively replaced by a new Ip-based (Internet protocol) PBX technology. The new way of switching voice-calls doesn't demand a separate infrastruc

In this report the characteristics of the electron applicator system for an Elekta SLi Plus linear accelerator have been studied. The investigation will serve as a basis for a new applicator design that will give less radiation leakage. The present applicator system does not fully comply with the recommendations of the International Electrotechnical Commission (IEC) Standards recording radiation l
