Symbolic Worst Case Execution Times
2011
In immediate or hard real-time systems the correctness of an operation depends not only upon its logical correctness, but also on the time in which it is computed. In such systems, it is imperative that operations are performed within a given deadline because missing this deadline constitutes the failure of the complete system. Such systems include medical systems, flight control systems and other systems whose failure in responding punctually results in a high economical loss or even in the loss of human lives. These systems are usually analyzed in a sequence of steps in which first, a socalled control flow graph (CFG) is constructed that represents possible program flows. Furthermore, bou…
Fetal growth restriction: A growth pattern with fetal, neonatal and long-term consequences
2019
Fetal growth restriction (FGR) or intrauterine growth restriction (IUGR) are the terms used for a fetus which has not attained its full growth potential for gestational age. FGR is a multifactorial syndrome responsible for increased fetal and neonatal morbidity and mortality as well as long term adverse outcomes involving auxological, metabolic, organic and functional domains. Clinicians distinguish early and late onset FGR, in relation to specific fetal anthropometric parameters related to the possible primary etiology and to different patterns of placental and maternal cardiovascular pathologies. Delivery of an early onset FGR or growth impaired newborn with congenital pathology should be…
Postnatal programming cardiometabolic risk : effects of moderate caloric restriction in adulthood
2016
Postnatal overfeeding (PNOF) in rodents induces early programming of cardio-metabolic risk. Our aim was to determine if a moderate diet restriction could restore cardio-metabolic alterations induced by PNOF.Immediately after birth, litters of C57BL/6 mice were either maintained at 9 (normal litter, NL), or reduced to 3 (small litter, SL) to induce PNOF. At weaning, all mice received a standard diet ad libitum (AL). At 6 month of age, half of the NL and SL mice were assigned to a moderate 20% calorie restriction (CR: NLCR, SLCR) for one month, while the other mice continued to eat AL (AL: NLAL, SLAL). Glucose and insulin tolerance tests, cardiac function (echocardiography), body composition …
A Perturbation Approach to Continuous-Time Portfolio Selection Under Stochastic Investment Opportunities
2013
This paper studies portfolio selection in continuous-time models with stochastic investment opportunities. We consider asset allocation problems where preferences are specified as power utility derived from terminal wealth as well as consumption-savings problems with recursive utility Epstein-Zin preferences. The paper approximates the associated dynamic programming problem by perturbing the coefficients of the stochastic dynamics. We represent the Hamilton-Jacobi-Bellman equation as a series of partial differential equations that can be solved iteratively in closed-form through computer algebra software, at any desired accuracy.
Master's level education in biomedical optics: four-year experience at the University of Latvia
2000
Pilot program for Master's studies on Biomedical Optics has been developed and launched at University of Latvia in 1995. The Curriculum contains several basic subjects like Fundamentals of Biomedical Optics, Medical Lightguides, Anatomy and Physiology, Lasers and Non-coherent Light Sources, Optical Instrumentation for Healthcare, Optical Methods for Patient Treatment, Basic Physics, etc. Special English Terminology and Laboratory-Clinical Praxis are also involved, and the Master Theses is the final step for the degree award. Following one four-year teaching experience, some observations, conclusions and eventual future activities are discussed.
From the shade into the sun: exploring pride and shame in students with special needs in Finnish VET
2021
This paper reports on a study of the dynamics of social emotions and social bonds between students and class teachers by analysing the narratives of students receiving intensive special support in the Finnish vocational education and training (VET) system. Pride refers to a strong and safe involvement in interaction, and shame implies intimidated social bonds. The analysis is based on abductive content analysis for which Greimas’ actant model worked as an analysis tool. We found some students showing high respect to their teachers who acted as senders setting the objects for students’ studying. Pride is based on the students’ experiences in achieving the objects, thereby pleasing their teac…
Teacher Shortages, Teacher Contracts and their Impacton Education in Africa
2007
Primary school enrolment rates are very low in francophone Africa. In order to enhance education supply, manycountries have launched large teacher recruitment programmes in recent years, whereby teachers are no longer engaged on civil servant positions, but on the basis of (fixed-term) contracts typically implying considerably lower salaries and a sharply reduced duration of professional training. While this policy has led to a boost of primary enrolment, there is a concern about a loss in the quality of education. In this paper we analyse the impact on educational quality, by estimating nonparametrically the quantile treatment effects for Niger, Togo and Mali, based on very informative dat…
Effects of a French remedial program on pupils’ educational outcomes
2018
International audience; Few studies have examined the French “Networks for Specialized Assistance to Pupils in Difficulty” (Rased). In this article, we evaluate the impact of receiving Rased services in the first year of primary schooling on academic success. Using data from a national panel study, we find inconsistency in student selection within Rased. Using matching methods, our results reveal that pupils who benefited from the program school have a higher probability of grade repetition and obtain significantly lower scores on the third grade national assessment, particularly in mathematics, compared to pupils with similar characteristics who did not take part in the program. This impac…
Analysis of Primary/Containment Coupling Phenomena Characterizing the MASLWR Design During a SBLOCA Scenario
2012
Today considering the world energy demand increase, the use of advanced nuclear power plants, have an important role in the environment and economic sustainability of country energy strategy mix considering the capacity of nuclear reactors of producing energy in safe and stable way contributing in cutting the CO2 emission (Bertel & Morrison, 2001; World Energy Outlook-Executive Summary, 2009; Wolde-Rufael & Menyah, 2010; Mascari et al., 2011d). According to the information’s provided by the “Power Reactor Information System” of the International Atomic Energy Agency (IAEA), today 433 nuclear power reactors are in operation in the world providing a total power installed capacity of 366.610 G…
On the influence of context-based complexity on information search patterns: An individual perspective
2014
Although context-based complexity measured as the similarity and conflict across alternatives is dependent on individual preference structures, existing studies investigating the influence of context-based complexity on information search patterns have largely ignored that context-based complexity is user- and preference-dependent. Addressing this research gap, this article elicits the individual preferences of decision makers by using the pairwise-comparison-based preference measurement (PCPM) technique and records individuals' search patterns using eye tracking. Our results show that an increased context-based complexity leads to an increase in information acquisition and the use of a mor…
