No full textSite-specific validation of turbulence models on large offshore wind farms for improving fatigue assessment
No full textWind turbines installed in a wind farm are typically subject to increased turbulence because they are in the wake of upstream wind turbines that generate additional turbulence. Accurate prediction of turbulence in wind farms is critical as it is proportional to wind turbine fatigue loads, power losses and prediction of wind farm lifetime. IEC Standard 61400-1 suggests the use of the semi-empirical turbulence model called Frandsen model, which was originally proposed in 1999. Since the development of the Frandsen model, the size of wind turbines and wind farms has increased significantly. Therefore, this work aims to determine the accuracy of two versions of the Frandsen model: Standard and Modified, when applied to large offshore wind farms experiencing a combination of atmospheric stability conditions. This is done by comparing the estimated wind farm turbulence under specific atmospheric stability conditions with measurements from Westermost Rough and Horns Rev 2. It was found that the atmospheric stability distribution and the distance of the upstream wake inducing wind turbine at the offshore site plays a significant role in the accuracy of the estimated turbulence from the Frandsen models. The estimated turbulence intensity from the Standard and Modified Frandsen models was found to be under-predicted with respect to the measured turbulence for all atmospheric stability conditions at both wind farms. For wind directions with wake flow for upstream wind turbines more than 10 rotor diameters away, the Modified Frandsen model showed better prediction of turbulence intensity compared to the Standard Frandsen model. On the other hand, for wind directions with wake flow for upstream wind turbines less than 10 rotor diameters away, the Standard Frandsen model showed better turbulence intensity estimation compared to the Modified Frandsen model. Among all atmospheric stability conditions, the turbulence intensity estimate was closest to the measured data for unstable conditions. It is suggested that this fact can be attributed to the presence of a significant number of unstable conditions in the offshore wind farms used for the design of the semi-empirical Frandsen model.Electrical Engineering | Sustainable Energy Technolog
Impact of Domestic M&A on Acquirer Shareholder`s Equity: Evidence from Oslo Stock Exchange
No full textThe clear majority of research studies that has been conducted in the field of mergers and acquisition (M&A) are performance studies of acquirer post-M&A. Researchers has tried to get an insight into whether an M&A deal has had a positive or a negative effect on the acquiring company. In addition, most of these studies have been conducted on the US and UK market and hence the author wish to contribute to the existing literature by performing a specific study on the Norwegian market.
In the following thesis, I examine the short-term/immediate impact of selected domestic mergers and acquisition (M&A) deals on acquirer`s shareholder`s equity in the Norwegian market and I also examine whether this impact is influenced by the method of payment.
The author follow in the footsteps of numerous empirical researchers in the field of M&A and use event-studies to evaluate the performance of Norwegian M&A deals. The analysis investigates the Cumulative Abnormal Return (CAR) that measures a stocks unexpected returns and thus can be understood as the stock`s market reaction to the M&A announcement. The interpretation of CAR is that the stock price will on average react positively to M&A announcements when the Cumulative Average Abnormal Return (CAAR) and Average Abnormal Return (AAR) is greater than zero and statistically significant. The analysis considers selected domestic M&A deals on the Norwegian market in the period of 1995-2015 which add up to 38 deals that fulfills specific criteria`s.
HYPOTHESIS 1: Cumulative Average Abnormal Return (CAAR) is positive in the event-window
The results for CAAR show conflicting results and only significant values for the event-window of [-10, 10] and [-1, 1]. Due to significant conflicting results, Hypothesis 1 cannot be supported and hence the author has not been able to conclude whether Norwegian domestic M&A deals has created value or not.
HYPOTHESIS 2: Average Abnormal Return (AAR) is positive around the announcement date [0, 1]
The results for AAR shows that we have high statistically significant positive AAR around the announcement date. This indicates that the market views the M&A activity positively and hence Hypothesis 2 is supported.
HYPOTHESIS 3: Cash-only deals are positively related to CAAR
HYPOTHESIS 4: Mix-deal are positively related to CAAR
The results are not in line with the theoretical discussion in this thesis and not what the author would have expected. The results show that cash-only deals underperform both stock-only and mix deals.
Unfortunately, the results are not statistically significant and thus Hypothesis 3 and Hypothesis 4 are not supported.M-I
Understanding foreign divestment : The impacts of economic and political friction
No full textPast research on foreign divestment has recognized the impact of economic and political differences1. However, the prior findings remain equivocal. We adopt the Positive Organizational Scholarship perspective to provide more contextualized insights into the effects of economic and political differences on foreign divestment. Specifically, we consider the juxtaposition of national differences and levels of firm interaction with the different contexts. Thus, we develop the concept of friction to assess levels of economic and political differences. We further argue that economic friction will have a curvilinear (U-shaped) effect on foreign divestment, whereas political friction will produce a monotonic (positive) effect. Moreover, we introduce ownership level as a moderator into the main hypotheses. Drawing on data from 2400 foreign subsidiaries of 310 Finnish multinational enterprises, from 1970–2010, we provide support for our main hypotheses, although the moderating effect of ownership levels is not supported. We further compare the effects of differences measured by friction with those measured by distance. Accordingly, our research highlights the importance of detecting specific conditions for the investigation of the impact of economic and political differences in the foreign divestment literature.© 2021 The Author(s).

ملتان میں فلسفے کی روایت
No full textIt is an established fact that Multan is one of the oldest cities of the world, which has a reputation of a living city for the last five thousand years. It has a great tradition of institution and thought which reflects its centers of worship, variety of religions and beliefs, compilation of holy book of "Rig Veda' and philosophical attainments and pursuits of the scholars. Great Muslim philosopher, historians, travelers and Sufies have visited this city, one way or the other. Nasir Khusrau (philosopher and a preacher), Al-Beruni (historian and scholar), Fakhar-ud-din Razi (interpreter and philosopher), Samauddin Multani, Abdullah Multani, Maulana Fateh-ullah and Bahauddin Zakariya Multani have become the major source of philosophical tradition in Multan. Atiq Fikri, Qazi Javed and Shabbir Ahmad Ghauri has traced this tradition and the author of this paper has utilized the sources as well as the cultural heritage of Sufi poets of this area

European Union Foreign Direct Investment in China: Evidence from a Panel Study of EU Manufacturing Firms, 1998-2007
No full textThe paper examines determinants of the EU‘s FDI into the China by using a newly available Manufacturing firm-level data set for the period 1998-2007 from the State Statistical Bureau of China. The theoretical framework of the paper builds on Dunning's ownership–location–internalization (OLI) paradigm, incorporating the institutional determinants to test international production by EU firms in emerging market. The paper analyses recent trends and patterns of EU FDI and its firms‘ characteristics in China. This study applies both static and dynamic panel data approaches (fixed effects and GMM system estimators) to test the presence of agglomeration effect of past FDI. It finds that EU FDI in China is positively associated with export intensity and labour cost. However, technology and profitability of the firm show unexpected results, not lining with theory in the study. The results further suggest that locational factors with regard to macroeconomic and legal environment are also considered by EU firms when deciding on FDI in China. The findings have important implications for practitioners and policymaking

Multilateral Trade Liberalisation and FDI: An Analytical Framework for the Implications for Trading Blocs
No full textThe proliferation of regional integration agreements (RIAs) over the past several years has led to significant changes in the global configuration of trade and investment activity. Multinational enterprises now face the prospect of multilateral trade liberalisation that could significantly affect the foreign direct investment (FDI) incentive structures that were established within the range of current RIAs. RIAs that provide preferential market access to member countries modify firms’ incentives to undertake FDI activities and can lead to various permutations of trade and investment creation and diversion. This article provides an analytical framework for understanding the implications of multilateral trade liberalisation for the incentive structures of firms to conduct FDI and discusses how multilateral liberalisation could undo many of the FDI activities that were initiated in response to previous RIAs.foreign direct investment, incentives, multilateral trade liberalisation, regional integration agreements, Demand and Price Analysis, Financial Economics, International Relations/Trade, Political Economy,
