Local Fractional Variational Iteration and Decomposition Methods for Wave Equation on Cantor Sets within Local Fractional Operators
Dumitru Baleanu,J. A. Tenreiro Machado,Carlo Cattani,Mihaela Cristina Baleanu,Xiao-Jun Yang
Abstract and Applied Analysis , 2014, DOI: 10.1155/2014/535048
Abstract: We perform a comparison between the fractional iteration and decomposition methods applied to the wave equation on Cantor set. The operators are taken in the local sense. The results illustrate the significant features of the two methods which are both very effective and straightforward for solving the differential equations with local fractional derivative. 1. Introduction Many problems of physics and engineering are expressed by ordinary and partial differential equations, which are termed boundary value problems. We can mention, for example, the wave, the Laplace, the Klein-Gordon, the Schrodinger’s, the telegraph, the Advection, the Burgers, the KdV, the Boussinesq, and the Fisher equations and others [1]. Recently, the fractional calculus theory was recognized to be a good tool for modeling complex problems demonstrating its applicability in numerical scientific disciplines. Boundary value problems for the fractional differential equations have been the focus of several studies due to their frequent appearance in various areas, such as fractional diffusion and wave [2], fractional telegraph [3], fractional KdV [4], fractional Schr?dinger [5], fractional evolution [6], fractional Navier-Stokes [7], fractional Heisenberg [8], fractional Klein-Gordon [9], and fractional Fisher equations [10]. Several analytical and numerical techniques were successfully applied to deal with differential equations, fractional differential equations, and local fractional differential equations (see, e.g., [1–36] and the references therein). The techniques include the heat-balance integral [11], the fractional Fourier [12], the fractional Laplace transform [12], the harmonic wavelet [13, 14], the local fractional Fourier and Laplace transform [15], local fractional variational iteration [16, 17], the local fractional decomposition [18], and the generalized local fractional Fourier transform [19] methods. Recently, the wave equation on Cantor sets (local fractional wave equation) was given by [35] where the operators are local fractional ones [16–19, 35, 36]. Following (1), a wave equation on Cantor sets was proposed as follows [36]: where is a fractal wave function. In this paper, our purpose is to compare the local fractional variational iteration and decomposition methods for solving the local fractional differential equations. For illustrating the concepts we adopt one example for solving the wave equation on Cantor sets with local fractional operator. Bearing these ideas in mind, the paper is organized as follows. In Section 2, we present basic definitions and

Abstract: The trap parameters of defects in Si/CaF2 multilayered structures were determined from the analysis of optical charging spectroscopy measurements. Two kinds of maxima were observed. Some of them were rather broad, corresponding to "normal" traps, while the others, very sharp, were attributed to stress-induced traps. A procedure of optimal linear smoothing the noisy experimental data has been developed and applied. This procedure is based on finding the minimal value of the relative error with respect to the value of the smoothing window. In order to obtain a better accuracy for the description of the trapping-detrapping process, a Gaussian temperature dependence of the capture crosssections characterizing the stress-induced traps was introduced. Both the normal and the stress-induced traps have been characterized, including some previously considered as only noise features.

Abstract: Financial forecast is the most important planning activity. Tools to achieve financial forecasting company budgets, unlike the balance sheet and income statement, not intended for external users, but domestic needs guidance in order to achieve the objective proposed in the next financial year:increase financial performance of the enterprise, reflected in increasing its value. Management forecasts, the budget is the main fields of business and to monitor compliance with budgetary provisions. Through budgeting are established affecting resources and responsibilities for each activity center. Thus, the budget is a forecast of ciphered resource damage and liability insurance for business objectives cost-effectively.
Stock Analysis of S.C. ROPHARMA S.A. the Example of Romanian Pharmaceutical Entity

Risk in Contemporary Economy , 2011,
Abstract: Stock performance analysis can not find a better place than after presentation of earnings per share, the latter being one of the indicators on the performance of companies listed on capital markets. Exchange rates are considered final term market performance of listed companies since they incorporate information concerning stock, but also financial and accounting data on the net result for the year, sales per share, dividend per share, book value per share, etc. Stock rate of action is the barometer of a company's overall performance, officially recognized by the public through the capital market. But changes in stock price is determined by the evolution of economic and financial results of the enterprise, but also investors' expectations about the possibilities of its development, progress and prospects the industry in which company operates, and national and international economic trends.
The Impact of the Application of IFRS on Reporting the Financial Position

Risk in Contemporary Economy , 2012,
Abstract: The application of IFRS in an economic entity’s accounting imposes the paying of special attention to not necessarily the similarities but most importantly to the differences which appear between the national referential and the IASB one. As regards the financial position of the entity, we may say that, more or less, all standards influence it, but some impose differences which must be mentioned.

Studia Universitatis Vasile Goldis Arad, Seria Stiinte Economice , 2011,
Abstract: This paper outlines a framework for lease vs buy analysis. It also hightlines various aspectsof the lease/buy decision. The decision to lease or buy needs a comparison of alternativefinancing arrangements for the use of an asset. We provide a format for comparing netpresent value of the options, taking into account the analzsis of lease and buy using loans.Net present value is a more simple criterion to use in practice than dicounting costs, directlyreflecting the increasing value of the company as a result of its decision.
Doctors and Organ Transplantation. Organ Donation for Transplant. Opinions and Medical Representations
Cristina GAVRILUTA,Mihaela FRUNZA
Postmodern Openings , 2012,
Abstract: Present article aims to identify a part of the patterns of representation and explanation of the low rate of organ donation among ICU physicians, neurologists and hospital neurosurgeons from Moldova’s region hospitals. The methodology used was a qualitative one. The results obtained from the interviews show that essentially there are three dominant explanatory models: the systemic model, the informative model, and the educational model. These three models show somehow the pessimistic attitude of medical professionals towards the issue of organ donation and organ transplant.On the other hand, these three new models we had identified can also be three major solutions that could improve the current situation.
THE ROLE AND IMPLICATIONS OF TELEMARKETING IN MEDIA. CASE STUDY: TRANSILVANIA EXPRES DAILY PUBLICATION OF BRASOV

Annals of the University of Petrosani : Economics , 2010,
Abstract: During crisis, one of the first measures taken by the leadership management is the reduction, sometimes major, of marketing budgets. But, during this period, the promotion is essential and neglecting the communication actions may lead to significant losses on a long term basis. In the current economic context, the main purpose of any promotional campaign should be to obtain a direct answer from those exposed to message. A solution in this sense is to create the telemarketing which may reduce costs even by half (if it is integrated within the general marketing strategy) and may significantly increase the amount of sales, offering many benefits, unable to be obtained through other sales techniques.
THE EFFICIENCY OF PROMOTIONAL INSTRUMENTS RELATED TO THE PRODUCT LIFE CYCLE STAGES
MIHAELA MARCU,CRISTINA GHERMAN
Annals of the University of Petrosani : Economics , 2010,
Abstract: Regarded as a planning tool, PLC (product life cycle) strongly contributes to the identification of the main marketing challenges that may arise throughout the life of a product/service. Thus, the marketing management has the opportunity to develop and implement those solutions designed to optimize each of the 4P of marketing mix: product (quality), price, distribution (placement) and promotion. The communication program has an essential role, because the company presents through it its "product" to actual or potential customers in order to convince them of the benefits of purchasing/using it. The efficiency of the promotional instruments involves an appropriate allocation of funds needed to promote the product/service in relation to the stage of its life cycle.
