A novel vague set approach for selective contrast enhancement of mammograms using multiresolution  [PDF]
Arpita Das, Mahua Bhattacharya
Journal of Biomedical Science and Engineering (JBiSE) , 2009, DOI: 10.4236/jbise.2009.28083
Abstract: The proposed algorithm introduces a novel vague set approach to develop a selective but robust, flexible and intelligent contrast enhancement technique for mammograms. Wavelet based filtering analysis can produce Low Frequency (LF) and High Frequency (HF) subbands of the original input images. The extremely small size microcalcifications become visible under multiresolution techniques. LF subband is then fuzzified by conventional fuzzy c-means clustering (FCM) algorithm with justified number of clusters. HF components, representing the narrow protrusions and other fine details are also fuzzified by FCM with justified number of clusters. Vague set approach captures the hesitancies and uncertainties of truly affected masses/other breast abnormalities with normal glandular tissues. After highlighting the masses/microcalcifications accurately, both LF and HF subbands are transformed back to the original resolution by inverse wavelet transform. The results show that the proposed method can successfully enhance the selected regions of mammograms and provide better contrast images for visual interpretation.
On the ALA Membership Pyramid

Abstract: “…i [sic] only renew [my ALA membership] out of a sense of professional obligation, and also because of the fear that i’ll [sic] put it on my resume and get busted as not being a member.” –c-dog Membership in the American Library Association means professionals are bound together by the tenets of librarianship. Technically, this [...]
Fuzzy Logic Strategy for Solving an Optimal Control Problem of Glucose and Insulin in Diabetic Human  [PDF]
Jean Marie Ntaganda
Open Journal of Applied Sciences (OJAppS) , 2013, DOI: 10.4236/ojapps.2013.37052

This paper aims at the development of an approach integrating the fuzzy logic strategy for a glucose and insulin in diabetic human optimal control problem. To test the efficiency of this strategy, the author proposes a numerical comparison with the indirect method. The results are in good agreement with experimental data.

Fuzzy Logic Approach for Solving an Optimal Control Problem of an Uninfected Hepatitis B Virus Dynamics  [PDF]
Jean Marie Ntaganda, Marcel Gahamanyi
Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.69136
Abstract: We aimed in this paper to use fuzzy logic approach to solve a hepatitis B virus optimal control problem. The approach efficiency is tested through a numerical comparison with the direct method by taking the values of determinant parameters of this disease for people administrating the drugs. Final results of both numerical methods are in good agreement with experimental data.
Participación de médicos residentes de un hospital pediátrico en las actividades científicas y de formación de la Sociedad Argentina de Pediatría
Davenport,María Carolina; Domínguez,Paula Alejandra; Martins,Andrea Elizabeth;
Archivos argentinos de pediatr?-a , 2012, DOI: 10.5546/aap.2012.155
Abstract: the sociedad argentina de pediatría, sap (argentine society of pediatrics) offers courses and scientific activities for pediatricians and residents. we evaluated the participation of pedro de elizalde hospital residents in the scientific and training activities of sap and assessed the trend of participation throughout the residency; 107 residents were surveyed; 48% were members, and the participation increased significantly throughout the residence (p <0.01). none of the surveyed residents were part of any association; 84% did not know the "pediatricians in training group"; 49% participated in continued training programs, with a growing tendency to participation through-out the residency (p <0.01); 80% considered that the sap is a friendly entity. we concluded that participation of residents in the sap is scarce during the frst two years of training, and that it shows a growth in the senior residents' group. encouraging the interest of frst and second year residents in the activities is necessary.
Why We Should Adopt ALAConnect: A brief review and rumination on ALA’s new online community
Emily Ford
In the Library with the Lead Pipe , 2009,
Abstract: So ALA has joined the ranks of two point oh. Last month it rolled out ALAConnect, a service influenced by Ning, LinkedIn, Facebook, Google Docs, and other online networking platforms and shared work spaces. Despite the hoopla about the system I hadn’t even heard of it until one of my working groups was asked to [...]
Ioan M. Anghel
Romanian Journal of European Affairs (RJEA) , 2002,
Abstract: Romania’s future EU membership requires a thorough reconsideration of the balance of power between the national state and the EU. The author argues that it is difficult, at present, to estimate what this balance will be like by the time Romania joins the EU. Therefore, the article looks at the current state of facts in the EU. Similarly to other international organisations, in the EU there is a transfer of suzerainty from the Member States to the common institutions. The difference consists however, in a higher degree of suzerainty loss, due to the fact that the EU has created supranational bodies, which can make binding decisions on behalf of the Member States. In the case of other international organisations, decisions are made only through the consensus of all participating states. This transfer of suzerainty has increased over time, as the Union evolved from a purely economic organisation to a political - and eventually a military - one. For Romania, one of the first consequences will be the modification of the Constitution and of other legislation.
On Development of Fuzzy Controller: The Case of Gaussian and Triangular Membership Functions  [PDF]
Abayomi M. Ajofoyinbo, Vincent O. S. Olunloyo, Oye Ibidapo-Obe
Journal of Signal and Information Processing (JSIP) , 2011, DOI: 10.4236/jsip.2011.24036
Abstract: In recent years, the use of Fuzzy set theory has been popularised for handling overlap domains in control engineering but this has mostly been within the context of triangular membership functions. In actual practice however, such domains are hardly triangular and in fact for most engineering applications the membership functions are usually Gaussian and sometimes cosine. In an earlier paper, we derived explicit Fourier series expressions for systematic and dynamic computation of grade of membership in the overlap and non-overlap regions of triangular Fuzzy sets. In another paper, we extended the methodology to cover cases of cosine, exponential and Gaussian Fuzzy sets by presenting explicit Fourier series representation for encoding fuzziness in the overlap and non-overlap domains of Fuzzy sets. This current paper presents the development of a “Fuzzy Controller” device, which incorporates the formal mathematical representation for computing grade of membership of Gaussian and triangular Fuzzy sets. It is shown that triangular approximation of Gaussian membership function in Fuzzy control can lead to wrong linguistic classification which may have adverse effects on operational and control decisions. The development of the Fuzzy controller demonstrates that the proposed technique can indeed be incorporated in engineering systems for dynamic and systematic computation of grade of membership in the overlap and non-overlap regions of Fuzzy sets; and thus provides a basis for the design of embedded Fuzzy controller for mission critical applications.

American Journal of Operations Research (AJOR) , 2012, DOI: 10.4236/ajor.2012.22017
Abstract: Based on the analysis of the properties of Γ-conclusion by means of deduction theorems, completeness theorems and the theory of truth degree of formulas, the present papers introduces the concept of the membership degree of formulas A is a consequence of Γ (or Γ-conclusion) in Lukasiewicz n-valued propositional logic systems, Godel n-valued propositional logic system and the R0 n-valued propositional logic systems. The condition and related calculations of formulas A being Γ-conclusion were discussed by extent method. At the same time, some properties of membership degree of formulas A is a Γ-conclusion were given. We provide its algorithm of the membership degree of formulas A is a Γ-conclusion by the constructions of theory root.
A New Fuzzy Control Model for Kidney Patients  [PDF]
Mina Lagzian, Mohammad Shirazian, Ali Vahidian Kamyad, Malihe Layeghian, Reza Hekmat
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.39161
Abstract: The final diagnosis of some diseases depends on many factors and information. Considering all these factors and reviewing all of them is a difficult process, thus providing a mathematical model that can simultaneously consider all these factors is a great help for physicians to diagnose and treat these diseases. In this paper, we propose a new fuzzy control model for kidney transplantation patients. For the inference and conclusion of this model, we use Mamdani approach. Also we employ a new method to smooth the well-known non-smooth piecewise membership functions, i.e. trapezoidal and half trapezoidal membership functions.
