Diffractive optics for quasi-direct space-to-time pulse shaping.
2008
The strong chromatic behavior associated with a conventional diffractive lens is fully exploited to propose a novel optical device for pulse shaping in the femtosecond regime. This device consists of two optical elements: a spatially patterned circularly symmetric mask and a kinoform diffractive lens, which are facing each other. The system performs a mapping between the spatial position of the masking function expressed in the squared radial coordinate and the temporal position in the output waveform. This space-to-time conversion occurs at the chromatic focus of the diffractive lens, and makes it possible to tailor the output central wavelength along the axial location of the output point…
Formation of ultrashort triangular pulses in optical fibers
2014
Specialty shape ultrashort optical pulses, and triangular pulses in particular, are of great interest in optical signal processing. Compact fiber-based techniques for producing the special pulse waveforms from Gaussian or secant pulses delivered by modern ultrafast lasers are in demand in telecommunications. Using the nonlinear Schr¨odinger equation in an extended form the transformation of ultrashort pulses in a fiber towards triangular shape is characterized by the misfit parameter under variety of incident pulse shapes, energies, and chirps. It is shown that short (1-2 m) conventional single mode fiber can be used for triangular pulse formation in the steady-state regime without any pre-…
Femtosecond parabolic pulse shaping in normally dispersive optical fibers
2013
Formation of parabolic pulses at femtosecond time scale by means of passive nonlinear reshaping in normally dispersive optical fibers is analyzed. Two approaches are examined and compared: the parabolic waveform formation in transient propagation regime and parabolic waveform formation in the steady-state propagation regime. It is found that both approaches could produce parabolic pulses as short as few hundred femtoseconds applying commercially available fibers, specially designed all-normal dispersion photonic crystal fiber and modern femtosecond lasers for pumping. The ranges of parameters providing parabolic pulse formation at the femtosecond time scale are found depending on the initia…
Financing public higher education in developing countries : the potential role of loan schemes
1986
The financing of education has emerged as a major topic of discussion among policy makers in recent years. There is evidence that in many developing countries, governments can no longer continue to increase spending on education at the high rates characteristic in the 1960s and 1970s. The macroeconomic environment has worsened, and there is keen intersectoral competition for public funds. Thus unless educational development moves away from its present heavy dependence on public funds, the expansion of education would be frustrated. One policy option is to increase the private financing of education. In this paper, we evaluate the potential effectiveness of loans schemes as a cost recovery i…
Atteindre l'éducation pour tous en 2015 est-il un objectif réalisable ?
2004
This paper is looking at the feasibility of achieving the objective of education for all, one of the millennium objectives set up by the international community for the year 2015. Among numerous obstacles on the road map, the author is focusing on the budgetary constraint, which has aggravated significantly during the past decade. Actually the gap between least advanced countries and the rest of the world is widening, and not narrowing. Two remedies are proposed by the donor community for assisting the least developed countries to fill the gap : first a more efficient utilisation of resources presently allocated to education, and it seems that the efficiency reforms which are proposed are o…
Projekts: SIA "Vidzemes muzikālais klubs LA Palma" dibināšana
2016
Maģistra darba „Projekts: SIA „Vidzemes muzikālais klubs LA Palma” dibināšana” ietvaros ir izstrādāts biznesa plāns jauna muzikālā kluba izveidei Cēsīs. Projekta mērķis ir radīt jaunu muzikālo klubu Vidzemē, kas sniegtu iespēju, galvenokārt, Vidzemes novada iedzīvotājiem rast vēlamo atpūtas un izklaides vietu, kurā būtu iespēja patīkami pavadīt laiku pēc darba nedēļas un nereti apmeklēt mūzikas mākslinieku koncertus. Dibinot jaunu šāda veida uzņēmumu Vidzemē, rastos iespēja paplašināt pieejamo izklaides industrijas piedāvājumu klāstu dažādu vecuma grupu iedzīvotājiem, radīt jaunas darbavietas, kā arī sekmēt viesu piesaisti Cēsu pilsētai. Maģistra darba izstrādes laikā ir izvērtēts jauna muz…
Projekts: Uzņēmuma "Burvju Pasaka" dibināšana
2017
Maģistra darba mērķis ir izstrādāt jauna uzņēmuma dibināšanas biznesa plānu. Darba autore maģistra darba laikā izstrādāja un novērtēja projekta uzņēmuma “Burvju pasaka” dibināšanas plānu. Projekta ideja ir nodibināt uzņēmumu, kas nodarbosies ar bērnu svētku organizēšanu Latvijā, Rīgā. Uzņēmums piedāvās bērnu svētku organizāciju ar sagatavotu programmu un animatoru speciāli aprīkotā bērnu istabā, telpu nomu(istaba aprīkota ar bērnu mēbelēm, kā arī izklaides) ar iespējām pieaicināt savu animatoru, kā arī iespēju pasūtīt speciālus papildpakalpojumus. Uzņēmējdarbības forma uzņēmumam “Burvju pasaka” ir sabiedrība ar ierobežotu atbildību. Vispiemērotākais nosaukums uzņēmumam būs “Burvju pasaka”. …
Projekts: Granulu ražotnes dibināšana
2020
Maģistra darba nosaukums ir „Projekts: granulu ražotnes dibināšana”. Paredzamais darbības uzsākšanas laiks ir 01.01.2021. Maģistra darba mērķis ir izveidot kokskaidu granulu ražotni vietējam tirgum, ar plānoto maksimālo ražošanas jaudu 12000 tonnas granulu gadā, kura 5 gadu laikā atpelnīs investētos 800000 EUR, iegūstot starptautisko ENPlus A1 granulu kvalitātes sertifikātu. Mūsdienās arvien vairāk cilvēku kā galveno apkures veidu izvēlas kokskaidu granulu apkures sistēmas, līdz ar to autors uzskata, ka projektā ražotam produktam būs perspektīva. Lai īstenotu projektu, ir plānots iegādāties bijušo zāģētavu Lielvārdes novada Lēdmanē. Lai īstenotu projektu, ir plānots iegādāties bijušo zāģēta…
An Outline for Funding Adaptation and Disaster Management Schemes
2012
This paper develops further a proposal to split continued climate negotiations into two separate blocks. The first block deals with historical emissions of greenhouse gases, including a mutual debt cancellation: the accumulated carbon debts of developed countries up to a cut-off year would be swapped for conventional monetary debts of developing countries. The second block deals with future emissions and how to finance adaption to climate change. Following the “polluter pays” principle, the funds should be collected in proportion to the responsibility for climate change and redistributed in proportion to the needs for adaption and management of climate-related risks. A system based on separ…
Modeling Requirements for Future CASE
1995
In this paper we discuss some requirements for future CASE Computer Aided Software/Systems Engineering environments. These requirements include increased modifiability and flexibility as well as support for process and agent models. We claim that they can only be addressed by developing more powerful representation and modeling techniques. As a possible basis for modeling various techniques, we outline a general information architecture for a future CASE environment. In addition, we propose primitive types for specifying techniques, the development process, and agent models, and use these types for modeling an example methodology and examine how the requirements are or can be supported in o…
