An Investigation into Eco-tourism Potential of the Alamut Region of Iran using SWOT Analysis Model
Keivan Saeb,Razieh Jafari Hajati,Shiva Rezai
Ecologia Balkanica , 2012,
Abstract: The present research examines the potentials and limitations of tourism in the Alamut region, offering suggestions and strategies for the promotion of tourism in this region. Research methodology adopted in this study is based on analytical-descriptive approach. To formulate and establish a sound research theoretical framework as well as to review the research literature, a questionnaire tooling method was used and the results were analyzed using the SWOT technique. While introducing the tourist attraction in the province, the influential factors in the region categorized into the four headings of: strengths; weaknesses; opportunities and threats were included in our considerations and strategies or guidelines for a sustained tourism development in the region provided. The research findings, taking into consideration the present status of the Alamut region, indicate that despite the fact that the region houses a great number of ancient sites and monuments and enjoys a high level of bio-diversity resources, making it the ideal candidate to be transformed into an exemplary tourist attraction pole, it is faced with major obstacles to reach this goal. In order to remove some of the problems of the region, strategic factors were analyzed and priorities delineated. The findings indicated that a focused attention and description of the values of the region is alleviated through the holdings of seminars or meeting and conferences as well as paving the way to give cultural knowledge and understanding to prevent inflicting widespread damages to the environment; to establish hotels; to provide welfare facilities and introduce natural resources as well as historical sites and their ancient heritage.
Rates of convergence for Renyi entropy in extreme value theory
Ali Saeb
Statistics , 2014,
Abstract: Max stable laws are limit laws of linearly normalized partial maxima of independent identically distributed random variables. Saeb (2014) proves that the Renyi entropy of order b (b > 1) of linear normalized maximum of iid random variables with continuous differentiable density is convergent to the Renyi entropy of order b of the max stable laws. In this paper, we study the rate of convergence result for Renyi entropy for linearly normalized partial maxima.
General extreme value modeling and application of bootstrap on rainfall data - A case study
Ali Saeb
Statistics , 2014,
Abstract: Extreme value theory is concerned with probabilistic and statistical questions related to very high or very low values in sequences of random variables and in stochastic processes. The subject has a rich mathematical theory and also a long tradition of applications in a variety of areas. Among many excellent books on the subject, Coles [2] while the book by concentrates on data analysis and statistical inference for extremes. In this article, we present a case study wherein we model annual maximum yearly rainfall data using the generalized extreme value distribution. Also, we use R software for data analysis and give the R codes in the appendix.
On Renyi entropy convergence of the max domain of attraction
Ali Saeb
Statistics , 2014,
Abstract: In this paper, we prove that the Renyi entropy of linearly normalized partial maxima of independent and identically distributed random variables is convergent to the corresponding limit Renyi entropy when the linearly normalized partial maxima converges to some nondegenerate random variable.
Can Country Image Change after Likable Incident? The Case of Chile Miners’ Rescue Operation and the Middle East Consumers
Saeb Farhan Al Ganideh
International Business Research , 2012, DOI: 10.5539/ibr.v5n3p100
Abstract: Country image plays a key role in influencing consumers’ perceptions towards products originating from foreign countries. Economic and commercial relations between countries in the Middle East region and South America have improved strongly in the last decade. However, there is a dearth of studies conducted in the Middle East countries regarding products sourced from South American countries. This study aims to explore how Chile miners’ rescue operation has been perceived by Jordanians and how it has influenced the country image of Chile. The study examines the influence of demographic variables and openness to other cultures on the attitudes of Jordanian consumers towards Chile miners’ rescue operation. A survey was conducted in the spring of 2011 to collect data from Jordanian consumers. Data were collected from 154 Jordanian customers. The results showed that Chile miners rescue operation has been admired most by Jordanian consumers who live in the capital of the country and by Jordanians who are more opened to other cultures.
On convergence of entropy of distribution functions in the max domain of attraction of max stable laws
Sreenivasan Ravi,Ali Saeb
Statistics , 2014,
Abstract: Max stable laws are limit laws of linearly normalized partial maxima of indepen- dent, identically distributed (iid) random variables (rvs). These are analogous to stable laws which are limit laws of normalized partial sums of iid rvs. In this paper, we study entropy limit theorems for distribution functions in the max domain of attraction of max stable laws under linear normalization. More speci?cally, we study the problem of convergence of the Shannon entropy of linearly normalized partial maxima of iid rvs to the corresponding limit entropy when the linearly normalized partial maxima converges to some nondegenerate rv. We are able to show that the Shannon entropy not only converges but, in fact, increases to the limit entropy in some cases. We discuss several examples. We also study analogous results for the k-th upper extremes.

Statistics , 2014,
Abstract: In this paper the Galton Watson branching process has been studied for a class of offspring distributions which are in a way sandwiched between the Bernoulli and Poisson.
A note on traveling wave solutions to the two component Camassa-Holm equation
Keivan Mohajer
Physics , 2008, DOI: 10.1142/S140292510900011X
Abstract: In this paper we show that non-smooth functions which are distributional traveling wave solutions to the two component Camassa-Holm equation are distributional traveling wave solutions to the Camassa-Holm equation provided that the set $u^{-1}(c)$, where $c$ is the speed of the wave, is of measure zero. In particular there are no new peakon or cuspon solutions beyond those already satisfying the Camassa-Holm equation. However, the two component Camassa-Holm equation has distinct from Camassa-Holm equation smooth traveling wave solutions as well as new distributional solutions when the measure of $u^{-1}(c)$ is not zero. We provide examples of such solutions.
On the peakon inverse problem for the Degasperis-Procesi equation
Keivan Mohajer
Physics , 2014,
Abstract: The peakon inverse problem for the Degasperis-Procesi equation is solved directly on the real line, using Cauchy biorthogonal polynomials, without any additional transformation to a "string" type boundary value problem known from prior works.
On linear resolution of powers of an ideal
Keivan Borna
Mathematics , 2008,
Abstract: In this paper we give a generalization of a result of Herzog, Hibi, and Zheng providing an upper bound for regularity of powers of an ideal. As the main result of the paper, we give a simple criterion in terms of Rees algebra of a given ideal to show that high enough powers of this ideal have linear resolution. We apply the criterion to two important ideals $J,J_{1}$ for which we show that $J^{k},$ and $J_{1}^{k}$ have linear resolution if and only if $k\neq 2.$ The procedures we include in this work is encoded in computer algebra package CoCoA.
