Abstract

Along with other Central and Eastern European counties, Czechia has invested significant effort in deterring refugees from entering the country during the ‘refugee crisis’. This article sheds light on the role of the media in legitimising anti-refugee policies by analysing the politicised discourse on refugees in 900 articles published in Czech newspapers between 2014 and 2016. The findings indicate that refugees were depicted as a security threat and an administrative burden partly imposed by the European Union. The article discusses the policy implications of depicting refugees in this way and thus broadens the literature on European narratives during the refugee emergency in Europe.

Abstract

Modern society has developed a growing dependence on electricity in order to carry out important societal functions. This implies the risk of cascading failures to society in the case of power shortage. The creation of a resilient and sustainable power energy system is therefore crucial. Equal crucial is the preparedness for the event of power shortage. As a part of the Swedish crisis management system, the Swedish Energy Agency (EM) has developed a planning system, STYREL, to identify social important objects in order to ensure important social functions in the case of power shortage. This article examines STYREL as a policy network and as a planning system to ensure a sustainable and resilient power supply. The study focus on the design of the system, the implementation of the system based on the results from the two rounds completed in 2010 and 2014. Using interviews with coordinators at the local and regional level in three counties and a survey including all 21 coordinators at the regional level, it indicates that the design of the planning system reviles opportunities for improvements of the planning system. The study also indicates that the coordinators at the local level lack trust in the planning system depending on both the lack of resource and the lack of feedback. This in turn indicates challenges for the system from a resilient and sustainability point of view.

Abstract

This article focuses on the effects of corrections to the budgetary policy in eurozone economies. The goal of the text is to check if advancement in implementing modern tools of public management is helpful in the time of fiscal adjustment. We assume that the most important role of a performance approach in conducting fiscal policy is the ability of government to implement active policy meant as structural changes in the composition of public expenditures. In the case of the need to cut general levels of public spending, public sector managers who have knowledge of performance effects of public policies should be able to conduct fiscal adjustment in such a way as to minimise negative outcomes of spending correction on society. The structure of the text is as follows. First, we present some insights on the economic effects of fiscal adjustment. Then, we discuss the concept of performance management presented in the theory and policy agendas of international institutions such as the European Union or the OECD (Organization for Economic Cooperation and Development). Finally, we present the result of an empirical exercise that is designed to combine the level of advancement in implementing performance budgeting (PB) and the social cost of fiscal adjustment in eurozone economies. The most important finding of the research is that PB tools seem to have very limited usefulness in a time of fiscal adjustment. There is no statistical evidence that countries advanced in utilisation of PB tools conduct more active fiscal policy – approach of cutting all expenditures across the border by given percentage rather than looking at priorities and social outcomes of fiscal adjustment dominates in all cases.

Abstract

Owing to the increase in the internet traffic, any calculation that requires more than linear time would be considered unreasonably moderate for constant applications. One cure is to utilize numerous processors to build up associations in parallel and the other is to construct low cost, high speed, large capacity non-blocking switching architecture. In this paper, our focus is on developing parallel algorithms for routing which will ensure high-speed internet connectivity and at the same time making the system to be cost effective.

Abstract

This paper focuses on designing and implementing of an inverter and particularly focuses on developing a low cost transformer-less voltage source conversion that has a higher efficiency as well as compact in size. The complete design consists of DC-DC converter and a DC-AC inverter. The converter is dependent on switched capacitor techniques and steps 12Vdc to 240Vdc. The inverter is dependent on a full-bridge configuration which produces a 240Vac output from 240Vdc. To achieve the improvement in inverter efficiency and a reduction in cost, the power transformer and magnetic components such as inductors are eliminated. In addition, inverter voltage control techniques such as pulse width modulation (PWM) and switching of MOSFETs are optimized through digital control using ATtiny26L microcontroller unit.

Abstract

This article approaches the attitude of Z Generation concerning the promoting of the Romanian Army Institution in social media. This domain is a rigorous one, based on serosity and there are not a multitude of common values with this generation. Technology is a world-known aspect and the IGeneration is known as being born with new technological culture and they do not require to adjust to it. They prefer socializing in online, capture some meaningful general knowledge from their intercommunications. The Internet proposes various techniques of enticing youngsters to consume a lot of time online, on their smart devices.

Abstract

Rain as a weather phenomenon is one of the things that greatly affects propagation of radio waves. Above 10 GHz, the attenuation brought about by the interaction of the propagating waves and the rain droplets becomes significant for both terrestrial radio links and satellite links. For this reason, rain attenuation models have been developed to aid in planning purposes for network implementation. The models use statistics to predict the attenuation that is caused by specific amount of rain and also the type of rain. This means that different regions will have different levels of attenuation due to the fact that they experience different types and amount of rain. A couple of models exist including the ITU-R, Moupfouma model, Crane attenuation model and other localized models depending on the geographical area that research data collection and extensive analysis has been conducted on and a comprehensive set of values and factors have been determined that can aid in estimation of attenuation due to rain. This paper seeks to provide a viable means by which a transmission engineer can be able to know the attenuation per kilometer due to the various models. This is achieved by designing a software calculator that provides the output of the attenuation per kilometer (dB/Km) while taking an input of rain rate for the different models available. The calculator is based on visual basic platform and works with forms.

Abstract

Lessons learned process enables an organization to learn from its mistakes and successes. Thanks to this process an organization can reduce the risk of repeating mistakes and increase the chance that successes are repeated. This article aims to present the results of the research, especially, results of the process analysis of sharing lessons in the Czech Armed Forces. Based on the procedural deficiencies identification, benchmarking comparisons with lessons learned process of other organizations were carried out. The purpose of the benchmarking was to do away with the above mentioned deficiencies. To use benchmarking was beneficial from the point of view of a simplified model processing. The final part of the article introduces set of recommendation including the optimized model of the lessons learned process.
