Dynamic programming (DP) is a fast, elegant method for solving many one-dimensional optimisation problems but, unfortunately, most problems in image analysis, such as restoration and warping, are two-dimensional. We consider three generalisations of DP. The first is iterated dynamic programming (IDP), where DP is used to recursively solve each of a sequence of one-dimensional problems in turn, ...
• Work schedule during pregnancy and spontaneous abortion. • Genetic evaluation of stillbirth in United States holsteins using a sirematernal grandsire threshold model. • Combining internal and external validation data to correct for exposure misclassification: A case study. • Activation of 5-HT1A receptors in the paragigantocellularis lateralis decreases shivering during cooling in the conscio...
Parametric study of the influence of cooling channel dimensions on PEM fuel cell thermal performance
In a polymer membrane fuel cell more than half of the chemical energy of hydrogen is converted to heat during generation of electricity. This causes an increase in the cell temperature. The Cooling field design has a significant role in cell cooling. The cell's performance and stability are reduced due to inappropriate heat dissipation. In this paper, the cooling flow and heat transfer in cooli...
conclusions dental academics were unsure about the means of infection and prevention against hbv. many of them had not completed the immunization scheme and did not have the test of seroconversion. the serological analysis revealed unprotection, even after students completed the vaccination schedule. results of the 179 students surveyed, 58.1% knew about the degree of virulence of the hepatitis...
It is not simple to model cross and auto-variograms to describe the covariation of two or more soil properties, since the models that are fitted must meet certain constraints. These constraints are most readily met by fitting a linear model of coregionalization (LMCR). This presents practical problems. Not all combinations of authorized variogram functions constitute a LMCR. This paper presents...
This paper provides an overview of research related to use of building thermal mass for shifting and reducing peak cooling loads in commercial buildings. The paper presents background on the concept and the problem of optimizing zone temperature setpoints and provides specific results that have been obtained through simulations, controlled laboratory testing, and field studies. The studies have...
We revisit Gaussian Adaptation (GaA), a black-box optimizer for discrete and continuous problems that has been developed in the late 1960’s. This largely neglected search heuristic shares several interesting features with the wellknown Covariance Matrix Adaptation Evolution Strategy (CMA-ES) and with Simulated Annealing (SA). GaA samples single candidate solutions from a multivariate normal dis...
background heat is a harmful factor in workplaces that causes physiologic and cognitive changes in workers. objectives the purpose of this study was to investigate the effect of cooling vest on heat strain and reaction time while wearing chemical-biological-nuclear protective clothes. methods twelve male students with mean age of 25 ± 2 and body mass index (bmi) of 23 ± 1.5 were recruited in th...
Keynote presentations Climate Reconstructions Challenges in Space and Time Johannes P. Werner and PAGES2k Reconstructing past climate is more than just an academic exercise. Knowing about the evolution of past climate can help us not only validating climate models, but also show what the future could bring things that happened in the past, like extreme droughts (Wetter et al. 2014), are valid s...
In a steam power plant, the temperature of the cooling water leaving the condenser for recyclingshould decrease. This is achieved in a cooling tower. The Heller cooling tower does not require waterfor operation, thus, it is a suitable system for use in thermal power plants throughout Iran. Wind is anenvironmental factor that unfavorably affects the performance of a cooling tower. Previous studi...
