A new optical interferometer for delay stabilization in attosecond pump/probe experiments is constructed, featuring a custom-made hole-drilled recombination mirror and using a co-propagating HeNe laser for the interference. The interferometer is shown to generate an interference pattern of high enough contrast for delay stabilization. The stability of the measured delay is tested with the interfer

This study focuses on the part of the policy process called implementation. Theorists like Lipsky (1980) and Rice (2012) assign the street-level bureaucrats a major role in this process. The street-level bureaucrats of object in this study are personnel on group homes for unaccompanied minors. Since the children do not have anyone else to look after them, it is the welfare states responsibility to

After the economic recession suffered during the eighties decade, the population under poverty conditions has increased dramatically. With the purpose of amend the situation; President Carlos Salinas has established the biggest anti-poverty program in Mexican history, the Programa Nacional de Solidaridad (PRONASOL). The following three administrations continued the implementation of these policies

In 1997 the Ugandan government introduced a reform program with the ambition to implement universal primary education. The abolition of tuition fees would ideally guarantee access to the public service delivery system as far as primary education is concerned and help to integrate underprivileged groups with the rest of the diverse society. The launch of universal primary education in Uganda implie

South East Asia, and Thailand in particular, are experiencing rapid population ageing. In Thailand older people are increasing in both proportion of the population and absolute number. Adaptations are needed to support this ageing population and to prevent poverty in old age. Since 2009 Thailand has had a minimum universal social pension, the Old Age Allowance (OAA) for all citizens aged 60 and ov

Issue of study: The plastic injection moulding industry has become highly competitive in terms of lead times and pricing, following an increase in low-cost manufacturing from Asia, as a part of the full supply chain. To remain competitive, mould tool manufacturers are looking to complement new tool manufacturing with local after-sales services in countries where their mould tools are being used. U

This report describes the methodology for performing a quantitative risk analysis for a unidirectional road tunnel. By using representative accident scenarios, a basic queue model and performing an evacuation analysis the amount of casualties for each scenario can be estimated. By using the described methodology it gives the decision-makers a good idea of the risk level in the tunnel. The results

Sammanfattning Digitala övervakningskameror har tidigare använts inom fenologisk forskning för att kunna mäta grönskan i trädkronor. Man har under en längre tid kunnat koppla lövträdets årscykel till klimatförändringar och på så sätt haft ett starkt incitament att studera sambandet. I denna uppsats utforskas möjligheten att applicera metoden med digitalkameror på ett nyligen kalhugget område för aAbstract The use of inexpensive digital cameras in phenological research has been acclaimed since results in previous research have shown that they are reliable and precise in measuring greenness of vegetation. The work of this thesis aims to broaden the applicability by studying how well the method performs when measuring the regrowth of a clear-cut area. This is needed to complement existing res

The advantages with infrared heating and the fact that the technology has become significantly more inexpensive opens up a bigger interest to develop products using infrared heaters further. What will the future kitchen look like? How can infrared technology develop and create more conventional and intellectual products processing our food? By pushing the limits of the technology today the main

This thesis investigates the stock return and its variance around seasoned equity offering announcements for Swedish companies listed on the OMX Large cap, Mid cap and Small cap exchanges. The analysis is made on a full sample containing 52 SEOs, as well as two sub-samples containing underwritten and non-underwritten SEOs. The framework for the event study is OLS regressions based on the CAPM-mode

As the spread of the internet continues, more people than ever search for medical information online when in need of health advice. Color is a prominent part of website aesthetics, and has been shown in the literature to have both positive and negative psychological effects. A total of 120 participants took part in the present study where the effect of the colors grey, blue, orange and red was tes

Popular science summary: Potential Distribution for the Endangered Asian Wild Ass Over the past century, large mammals have been globally under increasing pressure of humanized landscapes. Since extirpations of large herbivores are likely to have complicated consequences for the entire ecosystem, their conservation is a priority. With almost 81% threatened species, Perissodactyla (odd-toad ungu

The debate about the link between economic growth and foreign trade is still open amongst scholars. There exist four main hypotheses regarding the relation between imports, exports and economic growth. The first one states that growth can come only through increasing the volume of exports of the country, i.e. export – led – growth hypothesis. The second one (growth – led – exports hypothesis)

In digital integrated circuits, memories are often a limiter for main performance, power and area. Over the past decade, integrated memories have gained dominance in terms of area and power cost. In applications like machine learning or image processing the area share can be above 80% consuming more than 50% of the total power budget. On-chip memories in CMOS technologies can be categorized as sta

Cua Lo river mouth is a coastal inlet connected to an estuary at the central coast of Vietnam. The area is valuable for maritime trade, fishing industries, and tourism development. Natural disasters during the monsoon period are a problem, causing seasonal flooding. In connection to the inlet lies an elongating sand spit which causes erosion and destruction of residential areas on one side of the

This thesis investigates the effect of commuting time on labour supply using US household survey data. To circumvent biased estimates as working hours and commuting time are jointly determined by the worker, a first differences approach is carried out, in which changes in the commute are assumed to be exogenous. The estimates suggest that there is no causal effect on labour supply that can be deri
