Quasimonotone and Almost Increasing Sequences and Their New Applications
Hüseyin Bor
Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/793548
Abstract: Recently, we have proved a main theorem dealing with the absolute Nörlund summability factors of infinite series by using -quasimonotone sequences. In this paper, we prove that result under weaker conditions. A new result has also been obtained.
Power Increasing Sequences and Their Some New Applications
Hüseyin Bor
Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/436094
Abstract: In the work of Bor (2008), we have proved a result dealingwith summability factors by using a quasi--power increasing sequence. In this paper, we prove that result under less and more weaker conditions. Some new resultshave also been obtained.

International Journal of Mathematics and Mathematical Sciences , 2000, DOI: 10.1155/s0161171200002738
Abstract: A theorem on local property of|N¯,pn|k summability of factoredFourier series, which generalizes some known results, and also a general theoremconcerning the |N¯,pn|k summability factors ofFourier series have been proved.

International Journal of Mathematics and Mathematical Sciences , 2000, DOI: 10.1155/s0161171200002192
Abstract: We extended a theorem of Mishra and Srivastava (1983–1984) on |C,1|k summability factors, using almost increasing sequences,to |N¯,pn|k summability under weaker conditions.

Hüseyin Bor
International Journal of Mathematics and Mathematical Sciences , 2000, DOI: 10.1155/s0161171200003641
Abstract: We have established a relation between θ−|R,pn|k andθ−|R,qn|k summability methods, k>1, whichgeneralizes a result of Sunouchi (1949) on |R,pn| and|R,qn| summability methods.
On local property of absolute summability of factored Fourier series
Hüseyin Bor,Dansheng Yu,Ping Zhou
Mathematics , 2013,
Abstract: We establish two general theorems on the local properties of the absolute summability of factored Fourier series by applying a recently defined absolute summability, $\left\vert A,\alpha_{n}\right\vert _{k}$ summability, and the class $\mathcal{S}\left( \alpha_{n},\phi_{n}\right) $, which generalize some well known results and can be applied to improve many classical absolute summability methods.
Detection of Changes on Temperature and Precipitation Features in Istanbul (Turkey)  [PDF]
Hüseyin Turo?lu
Atmospheric and Climate Sciences (ACS) , 2014, DOI: 10.4236/acs.2014.44050
Abstract: In this study, the changes in the data of Istanbul’s precipitation and temperature and the features of these changes were analyzed by different methods. In the analyses the daily precipitation and temperature data sets of Florya and Goztepe Meteorological Stations which have similar locational features were used. These sets were recorded between 1960 and 2013 (for 54 years). In order to emphasize the differentiations in the last 15 years the analyses were conducted comparatively both for the 15-year and for the 54-year periods and then the results were evaluated. The changes in the monthly, annual and seasonal quantity, type and frequency of the precipitation in the form of rain and the features of the temperature’s monthly, annual and seasonal changes, the De Martonne aridity index and the Thornthwaite climate classification were carried out. The results showed that during the years from 1999 to 2013 the climate type of Istanbul changed from semi-humid climate to arid and less-humid climate. Most notably the precipitation during the warm periods has decreased, but the frequency of the intense rain has increased and the majority of these episodes of intense rain coincided with the warm periods. Other determinations were the rise in the annual average temperature and the extension of the warm periods in a year. This differentiation of the temperature features can lead to the aggravation of the evaporation and it can be effective for a longer period during the year. Being aware of this differentiation in the features of precipitation and temperature and taking these data into consideration in all sorts of planning and managing strategies have a special importance for the 14 million or more people living in Istanbul.
The Study of Teachers’ General Cynicism Inclinations in Terms of Life Satisfaction and Other Variables  [PDF]
Hüseyin Aslan, Ercan Yilmaz
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.49084
Abstract:

This research aims to examine teachers’ general cynicism inclinations in respect to some variables and life satisfaction level and the relevance of these inclinations with gender, relationship status and membership of a union. Research is carried out using relational inquiry module and the study group of it constituted of 395 primary school teachers who are working in Ankara during academic year of 2012-2013 and selected with the help of modeling of inordinate set. The data are collected with “The Scale of Life Satisfaction” and tested by making use of multiple regression technique. Whether the differentiation levels of teachers’ general cynicism inclinations are related with their genders, relationship status and their membership of a union are analyzed using T test. As a result, male teachers have higher degree of cynicism in cognitive dimension than female teachers. Moreover, these general cynicism inclinations in cognitive, affective and behavioral dimensions do not differ greatly according to teachers’ membership of a union and relationship status. It is observed that the cognitive and affective dimensions of general cynicism inclinations have negative-sided relation with teachers’ life satisfaction rates.

Application of Ant Colony Optimization for the Solution of 3 Dimensional Cuboid Structures  [PDF]
Hüseyin Eldem, Erkan ülker
Journal of Computer and Communications (JCC) , 2014, DOI: 10.4236/jcc.2014.24014
Abstract:

Traveling Salesman Problem (TSP) is one of the most widely studied real world problems of finding the shortest (minimum cost) possible route that visits each node in a given set of nodes (cities) once and then returns to origin city. The optimization of cuboid areas has potential samples that can be adapted to real world. Cuboid surfaces of buildings, rooms, furniture etc. can be given as examples. Many optimization algorithms have been used in solution of optimization problems at present. Among them, meta-heuristic algorithms come first. In this study, ant colony optimization, one of meta-heuristic methods, is applied to solve Euclidian TSP consisting of nine different sized sets of nodes randomly placed on a cuboid surface. The performance of this method is shown in tests.

Application of the Hybrid Differential Transform Method to the Nonlinear Equations  [PDF]
Inci ?ilingir Süngü, Hüseyin Demir
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.33039
Abstract: In this paper, a hybrid method is introduced briefly to predict the behavior of the non-linear partial differential equations. The method is hybrid in the sense that different numerical methods, differential transform and finite differences, are used in different subdomains. Our aim of this approach is to combine the flexibility of differential transform and the efficiency of finite differences. An explicit hybrid method for the transient response of inhomogeneous nonlinear partial differential equations is presented; applying finite difference scheme on the fixed grid size is used to approximate the space discretisation, whereas the differential transform method is used for time operator. Comparison of the efficiency of the different approaches is a very important aspect of this study. In our test cases, the hybrid approach is faster than the corresponding highly optimized finite difference method in two dimensional computations. We compared our hybrid approach’s results with the exact and/or numerical solutions of PDE which obtained from Adomian Decomposition Method. Results show that the hybrid approach may be an important tool to reduce the execution time and memory requirements for large scale computations and get remarkable results in predicting the solutions of nonlinear initial value problems.
