Iterative Methods for Obtaining Energy-Minimizing Parametric Snakes with Applications to Medical Imaging

Computational and Mathematical Methods in Medicine , 2012, DOI: 10.1155/2012/918510
Abstract: After a brief survey on the parametric deformable models, we develop an iterative method based on the finite difference schemes in order to obtain energy-minimizing snakes. We estimate the approximation error, the residue, and the truncature error related to the corresponding algorithm, then we discuss its convergence, consistency, and stability. Some aspects regarding the prosthetic sugical methods that implement the above numerical methods are also pointed out.

Abstract: Determination of organochlorine pesticides in drinking waterssampled from Cluj and Hunedoara counties. Pesticides are found scattered indifferent environmental factors (water, air, soil) wherefrom they are drawn off byvegetal and animal organisms. Water pollution by pesticides results from the plantprotection products industry and also from massive application of these resourcesin agriculture and other branches of economy. Pesticides can reach surface wateralong with dripping waters and by infiltration may reach the groundwater layers,organochlorine pesticides are most often found in the water sources (dieldrin,endrin, DDT, aldrin, lindane, heptachlor, etc.) due to their increased persistence inthe external environment. This study followed up the determination oforganochlorine pesticides in 14 drinking water samples collected from the outputof water treatment plants in Cluj and Hunedoara counties that process surfacewater and deep-water sources. For identification of organochlorine pesticides, thegas chromatographic method after liquid-liquid extraction was used, by a gascromatograph Shimadzu GC 2010 with detector ECD (Electron CaptureDetection). There were not detected higher values than the method detection limit(0.01 μg/l) in the drinking water samples collected and analyzed for both totalorganochlorine pesticides and components, which were well below the maximumconcentration admitted by Law 452/2002 regarding drinking water quality. Resultsare correlated with the sanitary protection areas for water sources and with the useof agricultural lands in the area. The solution to reduce risk of pesticides use isecological agriculture , which gains increasingly more ground in Romania too.
The IRIS Development Platform and Proposed Object-Oriented Data Base  [PDF]
Mihai-Octavian Dima
Journal of Software Engineering and Applications (JSEA) , 2015, DOI: 10.4236/jsea.2015.84017
Abstract: Various code development platforms, such as the ATHENA Framework [1] of the ATLAS [2] experiment encounter lengthy compilation/linking times. To augment this situation, the IRIS Development Platform was built as a software development framework acting as compiler, cross-project linker and data fetcher, which allow hot-swaps in order to compare various versions of software under test. The flexibility fostered by IRIS allowed modular exchange of software libraries among developers, making it a powerful development tool. The IRIS platform used input data ROOT-ntuples [3]; however a new data model is sought, in line with the facilities offered by IRIS. The schematic of a possible new data structuring—as a user implemented object oriented data base, is presented.

Abstract: In the paper we presented a method of sensorial evaluation for chicken meat (red and white). This is a descriptive method of analysis. It was perform with trained assessors for chicken refrigerated raw meat organoleptical evaluation. The sensorial attributes considered were: external aspect of anatomical part of chicken analyzed by slime, the surface odor, the skin and muscle color and muscular elasticity. Color was determined for the skin and white and red muscles. Our scale of analysis is formed by three values that characterize each quality attribute. The trained assessor appreciated the sensorial quality of raw anatomical part of chicken as excellent, acceptable and unacceptable. The objectives were: to establish the sensorial attributes to be analyzed for each type of muscular fiber, to describe the quality of each considered attribute and to realize a sensorial scale of quantification for the considered sensorial attributes. Our purpose was to determine the quality of the red and white refrigerated raw chicken anatomical parts (respectively for legs and breasts) after one week of storage.
Effect of the Spin-Spin Interaction on the Coulomb’s Law: Application to Ferromagnetism  [PDF]
Voicu Dolocan, Voicu Octavian Dolocan
World Journal of Condensed Matter Physics (WJCMP) , 2012, DOI: 10.4236/wjcmp.2012.23019
Abstract: In this work we present a model for the determination of the interaction energy for triplet and singlet states in atoms with incomplete filled shells. Our model includes the modification of the Coulomb’s law by the interaction between the magnetic moments of the electrons. We find that the energy of the triplet state is lower than the energy of the singlet state. We calculate the interaction energy between the electrons from the adjacent atoms in fcc lattices and we find that the minimum interaction energy is attained for the triplet state. The result is presented for the interaction between the electrons of the first coordination group and those of the second coordination group. The interaction energy which aligns the spins is used to evaluate the Curie temperature in a mean field model.
Some thoughts about the question of
Imre Gurzó,István Molnár

Abstract: The paper presents the main features of the policies which were followed by the left-liberal governments between 2002-2010. It sketches the state of the economy in Hungary in spring 2010, the most important measures taken by the Orbán government and the challenges, open questions and problems which need to be solved. It describes the most important political, economic, business, social, institutional and regional effects of Hungary’s EU membership, and in the end tries to sum up some important questions about the possible future.

Abstract: The paper presents the process of the Hungarian economy and society getting into crisisafter 2002. It also analyses the factors that caused the crisis and its effects. Further on, thepaper gives an overview about the measures that have been taken by the new governmentsince 2010, so that the country can get out of this situation.
Linear operators that preserve some test functions
Octavian Agratini
International Journal of Mathematics and Mathematical Sciences , 2006, DOI: 10.1155/ijmms/2006/94136
Abstract: The paper centers around a pair of sequences of linear positive operators. The former has the degree of exactness one and the latter has its degree of exactness null, but, as a novelty, it reproduces the third test function of Korovkin theorem. Quantitative estimates of the rate of convergence are given in different function spaces traveling from classical approximation to approximation in abstract spaces. Particular classes are also studied.
Restitution: Oina – Romanians’ national game
Octavian Lupei
Timisoara Physical Education and Rehabilitation Journal , 2011,
Abstract: The game oina is a manifestation of social life and is practicated especially by children and adolescents with the purpose of knowledge sharing. Oina recalls the main occupation of our ancestors: shepherding. The game was practiced in the old days by boys and girls during the Easter holidays.
