Hur är Generation Y som investerare?Süllü, Zeynep, Duru, Merve January 2016 (has links)
The empirical data indicates that Generation Y generally has a very high average financial literacy. The rationality they exhibit in the mastery of financial information and tools does not affect their savings and investments. Instead, the investment behavior is given in expression by their character, but also demographic basis.

Optimal Control and Its Application to the Life-Cycle Savings ProblemTaylor, Tracy A 01 January 2016 (has links)
Throughout the course of this thesis, we give an introduction to optimal control theory and its necessary conditions, prove Pontryagin's Maximum Principle, and present the life-cycle saving under uncertain lifetime optimal control problem. We present a very involved sensitivity analysis that determines how a change in the initial wealth, discount factor, or relative risk aversion coefficient may affect the model the terminal depletion of wealth time, optimal consumption path, and optimal accumulation of wealth path. Through simulation of the life-cycle saving under uncertain lifetime model, we are not only able to present the model dynamics through time, but also to demonstrate the feasibility of the model.

Energy efficient design of an adaptive switching algorithm for the iterative-MIMO receiverMohd Tadza, Noor Zahrinah Binti January 2015 (has links)
An efficient design dedicated for iterative-multiple-input multiple-output (MIMO) receiver systems is now imperative in our world since data demands are increasing tremendously in wireless networks. This puts a massive burden on the signal processing power especially in small receiver systems where power sources are often shared or limited. This thesis proposes an attractive solution to both the wireless signal processing and the architectural implementation design sides of the problem. A novel algorithm, dubbed the Adaptive Switching Algorithm, is proven to not only save more than a third of the energy consumption in the algorithmic design, but is also able to achieve an energy reduction of more than 50% in terms of processing power when the design is mapped onto state-of-the-art programmable hardware. Simulations are based in MatlabTM using the Monte Carlo approach, where multiple additive white Gaussian noise (AWGN) and Rayleigh fading channels for both fast and slow fading environments were investigated. The software selects the appropriate detection algorithm depending on the current channel conditions. The design for the hardware is based on the latest field programmable gate arrays (FPGA) hardware from Xilinx R , specifically the Virtex-5 and Virtex-7 chipsets. They were chosen during the experimental phase to verify the results in order to examine trends for energy consumption in the proposed algorithm design. Savings come from dynamic allocation of the hardware resources by implementing power minimization techniques depending on the processing requirements of the system. Having demonstrated the feasibility of the algorithm in controlled environments, realistic channel conditions were simulated using spatially correlated MIMO channels to test the algorithm’s readiness for real-world deployment. The proposed algorithm is placed in both the MIMO detector and the iterative-decoder blocks of the receiver. When the final full receiver design setup is implemented, it shows that the key to energy saving lies in the fact that both software and hardware components of the Adaptive Switching Algorithm adopt adaptivity in the respective designs. The detector saves energy by selecting suitable detection schemes while the decoder provides adaptivity by limiting the number of decoding iterations, both of which are updated in real-time. The overall receiver can achieve more than 70% energy savings in comparison to state-of-the-art iterative-MIMO receivers and thus it can be concluded that this level of ‘intelligence’ is an important direction towards a more efficient iterative-MIMO receiver designs in the future.

A study of membrane properties on air conditioning performanceBoyer, Elizabeth J. January 1900 (has links)
Master of Science / Department of Chemical Engineering / Mary E. Rezac / Mary E. Rezac / Energy consumption due to heating, ventilation, and air conditioning amounts to 10-20% of global electrical energy usage. Air conditioning alone uses one trillion kilowatt hours globally. This energy is required for the dehumidification of air in addition to its cooling. New membrane technologies have the potential to decrease air conditioning energy requirements by significant amounts. A membrane acts as a partial heat and mass exchanger in conjunction with a traditional air conditioning system to remove water content and reduce the cooling load. Membranes vary according to their properties and method of mass transport. Liquid membranes have high permeability and selectivity, dense membranes have high selectivity and low permeability, and porous membranes have low selectivity and high permeability. A theoretical model was created to observe how membrane properties affected the potential energy savings of such systems. The most influential properties were flow rate, water permeability and selectivity, membrane area and thickness, and the purge flow temperature. Other properties were determined to be minimally important such as outdoor temperature and humidity. The effect on energy savings in many cases was not a linear relationship but suggested an optimal value beyond which energy savings did not significantly increase. The best simulations showed electrical energy savings of 86-95%.

Finansiell förmåga och pensionsplanering : En empirisk studie om sambandet mellan finansiell förmåga och pensionsplanering i Norge / Financial literacy and retirement planning : An empirical study on the relationship between financial literacy and retirement planning in NorwayNyberg, Victoria January 2016 (has links)
Stigande förväntade livslängder har tillsammans med sjunkande födelsetal bidragit till en omvandling av pensionssystemet i ett antal länder. I sin tur har det medfört en större individhantering och därmed större krav på den enskilda individens kompetens. Tidigare studier visar att finansiell förmåga tenderar att vara låg i välutvecklade länder, ett positivt samband mellan individens finansiella förmåga och pensionsplanering har också urskilts. Ur detta perspektiv kan den ökade individhanteringen ses oroväckande och skapa ogynnsamma förutsättningar för goda ekonomiska utfall både för samhället och den enskilda individen. De tidigare studierna behandlar främst nivåerna av finansiell förmåga och pensionsplanering samt hur de samvarierar i tvärsnitt. För att skapa en bättre förståelse för sambandet mellan finansiell förmåga och pensionsplanering ämnar denna uppsats att studera sambandet över tid. Uppsatsen baseras på ett datamaterial från Norge, där en förändring i pensionssystemet implementerats 2011. Sambandet mellan individens finansiella förmåga och pensionsplanering studeras med regressionsanalyser. Resultatet från regressionsanalyserna tyder på att en förändring i den finansiella förmågan inte kommer leda till en förändring av individens pensionsplanering. Uppsatsens resultat ger inte stöd för ett kausalt samband mellan finansiell förmåga och pensionsplanering i Norge. De tidigare studierna i andra länder har fått stöd för ett kausalt samband. Om sambandet mellan finansiell förmåga och pensionsplanering är detsamma eller liknande i ett internationellt perspektiv väcker uppsatsens resultat ytterligare frågor kring hur sambandet och mekanismen bakom finansiell förmåga och pensionsplanering verkligen ser ut. Om en önskan att öka individers pensionsplanering finns ges inga tydliga svar på vilka åtgärder som är lämpliga och genererar resultat. / Rising life expectancies together with declining birth rates have contributed to a transformation of the pension system in several countries. In turn, the transformation has resulted in a greater individual management of the pensions and thus greater demands on the individual’s skills. Previous researches have shown that financial literacy tends to be low in well-developed countries, they have also distinguished a positive relationship between an individual’s financial literacy and retirement planning. From this point of view, the increased individual management could cause concerns and create unfavorable conditions for positive economic outcomes for the society as well as the individual. The previous researches have mainly dealt with the levels of financial literacy and retirement planning and how they co-vary in cross section. The thesis intends to study the relationship between financial literacy and retirement planning over time, to achieve a better understanding of the relationship. The thesis is based on a dataset from Norway, where a change in the pension system was implemented in 2011. The relationship between the individual's financial literacy and retirement planning is examined with regression analyzes. The results from the regression analyzes indicate that a change in the individual’s financial literacy do not have an impact on the retirement planning. The thesis results do not provide support for a causal relationship between financial literacy and retirement planning in Norway. The previous researches in other countries do provide support for a causal relationship. If the relationship between financial literacy and retirement planning is the same or similar in an international point of view, the results raises further questions about how the relationship appears and how the mechanism works. If there is a desire to enhance individuals' retirement planning the thesis result give no simple answers to what actions that are appropriate and generate results.

Aplikace heuristik při řešení rozvozní úlohy / Application of Heuristics on Vehicle Routing ProblemGerlich, Michal January 2011 (has links)
This thesis deals with solving a real case from one specific part of Operations Research -- Discrete Models. The case can be classified as Vehicle Routing Problem (VRP) which is a subset of classical Travelling Salesman Problem (TSP). The VRP is modified TSP when requirements of customers and capacities of trucks play role. The data needed for calculations were taken from the real situation of Pivovar Svijany a.s. The problem can be defined as VRP with cars with different capacities and split delivery. Even though the mathematic model of the problem is known and described in the thesis, the size of the problem is too big to be optimized. Therefore heuristic was used to solve it. Because of the good computational results in the past the savings algorithm was chosen. Its model was set using Visual Basic for Applications (VBA). The thesis (among others) analyses the sensitivity of the output on the values of the factors that can be chosen by the analyst. At the end of the thesis the best found solution is presented and the initial and the new scheme of the circles are compared.

Do foreign tax evaders use the United States as a tax haven?Tuinsma, Tijmen January 2019 (has links)
Tax havens are of signicant importance in the current global economy. The wealth hidden in these havens is estimated to add up to $6000 billion and this issue is linked with wealth inequality and money laundering. Identication of tax havens differs between sources, and blacklists are often politicised. Activists, experts and academics have claimed recently that the US serves as a tax haven for foreign tax-evading households. The tax environment in the US does favor foreigners; they are for example exempt from paying taxes on interest income generated by bank deposits and it is easy to set up entities hiding the identity of the ultimate owner. The effects of two international initiatives implemented to battle tax evasion in offshore centres are studied in this paper. These are the European Savings Directive and the Common Reporting Standard, under which the US does not cooperate. Using bilateral cross-border bank deposit data, it is estimated whether tax evaders moved their wealth to the US as a result of these measures. The results of the difference-in-difference approach neither confirm nor reject the claims that the US is being used as a tax haven by foreign households. Estimates on the effects in cooperating tax havens can not rule out the possibility that the Common Reporting Standard did not have its intended effect on tax evaders.
