KAJIAN PENANGGULANGAN KERUSAKAN LAHAN AKIBAT PERUBAHAN PENGGUNAAN LAHAN DENGAN PENDEKATAN MODEL HIDROLOGI PADA DAS PAMI
2018
<em>Changes in land use in watershed will affect peak discharge and degradation land. It is becoming an indicator of better or worse use of land in watershed area. This study aims to analysis land use change, to predict peak flows based on changes in land use and land use change scenarios in the Pami watershed. This study uses a number of primary data and secondary data. Primary data were obtained from observations of the condition of the land and soil sampling, which is then analyzed in the laboratory. Secondary data were obtained from literature and related agencies such as geographical map and thematic maps including land map, administrative area maps, land use maps in 1996-2015 an…
Geographical variation in pharmacological prescription
2009
Promoting rational drug administration in treatments is one of the most important issues in Public Health. Bayesian hierarchical models are a very useful tool for incorporating geographical information into the analysis of pharmacological prescription data. They allow the mapping of spatial components which express the trend of geographical variation. In addition, these models are able to deal with uncertainty in a sequential way through prior distributions on parameters and hyperparameters. Bayes' theorem combines all types of information and provides the posterior distribution which is computed through Markov Chain Monte Carlo (MCMC) simulation methods. Simulated data for pharmacological …
Studies of methods and tools for the really mixed visual coherence applied to the patrimony
2013
The work described in this report has as a target the mixed reality device ray-on, developed by the on-situ company. This device, dedicated to cultural heritage and specifically architectural heritage, is meant to be installed on-site and shows the user an uchronic view of its surroundings. As the chosen stance is to display photo-realistic images, two trails were followed: the improvement of the real-virtual merging by reproducing accurately the real lighting on the virtual objects, and the development of a real-time segmentation method which is resilient to lighting changes.Regarding lighting reproduction, an image-based rendering method is used in addition to a high dynamic range capture…
Automated Determination of Paroxetine and Its Main Metabolite by Column Switching and On-Line High-Performance Liquid Chromatography
1994
An automated column-switching method coupled to isocratic high-performance liquid chromatography has been developed for simultaneous determination of blood levels of paroxetine and its nonconjugated main metabolite BRL 36610. The lower limits of detection were 9-15 nmol/L (3-5 ng/ml) and linearity between drug concentration and detector response was found for 0-1,500 nmol/L (0-500 ng/ml). The method could be applied to the analysis of serum samples obtained from depressed patients who were treated with daily oral doses of 20 or 40 mg of paroxetine. After the 20-mg dose, the mean blood level of paroxetine was 69 nM (23 ng/ml), whereas the metabolite BRL 36610 was detectable in only one of 5 …
Recent Advances in the Morphology of Myositis
1985
Summary Myositis in man may be divided into infectious and non-infectious forms. The myopathologist more often deals with the latter forms which comprise dermatomyositis/polymyositis, inclusion body myositis, mixed connective tissue disease/collagenoses, and granulomatous myopathies. Modern morphological techniques as enzyme-histochemistry, electron microscopy, immunohistology, and morphometry are of different value in various forms of myositis, but are often indispensable techniques in up-to-date diagnostic work up of a myositis.
Desigualdades y mortalidad por cirrosis en varones (Zaragoza, 1996-2003)
2011
ResumenObjetivosAnalizar diferencias geográficas en la mortalidad por cirrosis hepática, en varones, en la provincia de Zaragoza, y su posible asociación con indicadores socioeconómicos, así como identificar la adecuación, en el ámbito rural, del índice de privación del proyecto MEDEA.MétodosLa unidad geográfica de análisis para Zaragoza capital fue la sección censal, y para el resto de la provincia el municipio. Para cada unidad de análisis se calculó la razón de mortalidad estandarizada cruda y suavizada mediante un modelo lineal generalizado mixto bayesiano. Se calculó un índice sintético de privación y se incluyó en el modelo en cuartiles. También se realizó el análisis exploratorio inc…
Reducing Electric and Thermal Energy Needs in Buildings by Using Innovative Envelope Materials
2018
The life style of building occupants is continuously arising towards conditions that are more comfortable involving, on turn, the growing of the electric energy consumptions for climatization purposes. This calls for the improvement of the efficiencies of equipment along with environmental performance of building materials. Laboratory analyses of samples of mixed materials, utilizing tomato stems harvested in Sicily and Cataluna, have been conducted Thermal conductance and mechanical properties have been detected for different rates of bio-component and inert materials. First results of the thermal properties seem to situate such bio-composites among the insulating building materials, for a…
A GRASP heuristic for the mixed Chinese postman problem
2002
Abstract Arc routing problems (ARPs) consist of finding a traversal on a graph satisfying some conditions related to the links of the graph. In the Chinese postman problem (CPP) the aim is to find a minimum cost tour (closed walk) traversing all the links of the graph at least once. Both the Undirected CPP, where all the links are edges that can be traversed in both ways, and the Directed CPP, where all the links are arcs that must be traversed in a specified way, are known to be polynomially solvable. However, if we deal with a mixed graph (having edges and arcs), the problem turns out to be NP -hard. In this paper, we present a heuristic algorithm for this problem, the so-called Mixed CPP…
Analysis and design of sequencing rules for car sequencing
2009
Abstract This paper presents novel approaches for generating sequencing rules for the car sequencing (CS) problem in cases of two and multiple processing times per station. The CS problem decides on the succession of different car models launched down a mixed-model assembly line. It aims to avoid work overloads at the stations of the line by applying so-called sequencing rules, which restrict the maximum occurrence of labor-intensive options in a subsequence of a certain length. Thus to successfully avoid work overloads, suitable sequencing rules are essential. The paper shows that the only existing rule generation approach leads to sequencing rules which misclassify feasible sequences. We …
The Hierarchical Mixed Rural Postman Problem: Polyhedral analysis and a branch-and-cut algorithm
2017
[EN] The Hierarchical Mixed Rural Postman Problem is defined on a mixed graph where arcs and edges that require a service are divided into clusters' that have to be serviced in a hierarchical order. The problem generalizes the Mixed Rural Postman Problem and thus is NP-hard. In this paper, we provide a polyhedral analysis of the problem and propose a branch-and-cut algorithm for its solution based on the introduced classes of valid inequalities. Extensive computational experiments are reported on benchmark instances. The exact approach allows to find the optimal solutions in less than 1 hour for instances with up to 999 vertices, 2678 links, and five clusters.
