It is a popular belief supported by proof: that nothing further can be achieved by an additional completion of the Real number system.Here I reconstruct the reals from a particular implementation of the reals ,(using the Cantorian method of partitioning convergent sequences), producing a surprising result. A coupled infinitesmial point structure with a completed interior. This gives rise to a natural interpretation of Color as an intrinsic feature of geometry. As apposed to a mere method of labeling.
In a sense then: I simply open further discussions here on the properties of geometry, and ask now:
What really then is geometric-color ?

In this paper we propose a new method for solving
the Automatic Aircraft Recognition (AAR) problem from a sequence of images of an unknown observed aircraft. Our method exploits the knowledge extracted from a training image data set
(a set of binary images of different aircrafts observed under three different poses) with the fusion of information of multiple features
drawn from the image sequence using Dezert-Smarandache Theory (DSmT) coupled with Hidden Markov Models (HMM).

This paper presents an innovative algorithm for improvement of the walking robot dynamic stability, using the Desert Smarandache Theory (DSmT) and the neutrosophic logic set. Starting from the hybrid force-position control, by applying the Robot Neutrosophic Control (RNC) method we extend the fuzzy control for walking robot stability motion on uneven terrain and in unstructured environments. Results analysis through virtual experimentation for motion control of a mobile walking robot proves that the neutrosophic logic leads to performance improvement of real time control through robustness, adaptation to robot's environment, efficient control and fast and clear identification of robot states.

Feature extraction is an important part in Content-based image retrieval (CBIR).It is an active research area over the past
few decades. In this paper texture feature extraction of mammogram images are done. Biorthogonal wavelet filter via lifting scheme is
used for the extraction of texture features. Maximum likelihood estimator (MLE) is used for texture feature estimation. Here Digital
Database for Screening Mammography (DDSM) is used as the database. Here biorthogonal wavelets are used in the lifting scheme to get texture feature vectors of mammogram images. By using lifting scheme in all biorthogonal wavelets, predict and update filter coefficients are also got. These coefficients will be adapted later and thus we can find the optimal wavelet filter bank for increasing the retrieval performance of the retrieval system. By using lifting scheme methodology decomposition of images are done and thus got approximation and detail coefficients of image.

The theory of fuzzy sets, which was initiated by Zadeh in his seminal paper [33] in 1965, was applied to generalize some of the basic concepts of
algebra. The fuzzy algebraic structures play a vital role in mathematics with wide applications in many other branches such as theoretical physics, computer sciences, control engineering, information sciences, coding theory, logic, set theory, real analysis, measure theory etc.

In this paper, we analyzed the problem of consructing a family of surfaces from a given some special Smarandache curves in Euclidean 3-space. Using the Frenet frame of the curve in Euclidean 3-space, we express the family of surfaces as a linear combination of the components of this frame, and derive the necessary
and sufficient conditions for coefficents to satisfy both the asymptotic and isoparametric
requirements. Finally, examples are given to show the family of surfaces with common Smarandache curve.

Clustering has been applied in many field of
management for better decision making with a lot of algorithms such as K-means. Based on Extenics, we found that most of algorithms calculate the similarity of elements in a certain set by distance to each other; they focus on the position
of each element and neglect their criteria. However, in the real world, there are usually exist criteria to score the elements.
Therefore, we present a new clustering method. In our method,we use distance in Extenics for similarity calculating based on criteria, and compared a simple case with traditional K-means
algorithm. The results show that our method is more practical and has much potential value for data mining and knowledge management.

As we known, an objective thing not moves with one’s volition, which implies that all contradictions, particularly, in these semiotic systems for things are artificial. In classical view, a contradictory system is meaningless, contrast to that of geometry on figures of things catched by eyes of human beings. The main objective of sciences is holding the global behav-
ior of things, which needs one knowing both of compatible and contradictory systems on things. Usually, a mathematical system included contradictions is said to be a Smarandache system.

A Smarandache multi-space is a union of n dierent spaces equipped with some dierent structures for an integer n 2 which can be used both for discrete or connected spaces, particularly for geometries and spacetimes in theoretical physics. In this paper, applying the Smarandaches notion and combining this with hyperrings in hyperring theory, we introduce the notion of multi-hyperring space and initiate a study of
multi-hyperring theory. Some characterizations and properties of multi-hyperring spaces are investigated and obtained. Some open problems
are suggested for further study and investigation.

Groenewald introduced of a completely prime ideal of a near ring [5]. In 2002, W.B. Vasanth Kandasamy study samaradache near ring, (samaradache ideal, of a near ring [7]. In 2012 H.H. Abbass and M.A.Mohommed introduced the notion of a completely prime ideal with respect to an element of a near ring [3].
In this work, we introduce a Samaradache completely prime ideal with respect to an element related to a near field of near ring as we mentioned in the abstract.

Stronger algebraic structure means a structure which satises more axioms, by proper subset one can understand a subset dierent from the empty set, by the unit element if any, and from the whole set.

A dominating set of a graph n(G), is a total lict dominating set if the dominating set does not contain any isolates. The total lict dominating number t(n(G)) of G is a minimum cardinality of total lict dominating set of G. The current paper studies total lict domination in graph from an algorithmic point of view. In particular we had obtained the algorithm for a total lict domination number of any graph. Also we had obtained the time complexity of a proposed algorithm. Further we discuss the NP-Completeness of a total lict domination number of the split graph, bipartite graph and chordal graph.

In the case of finite dimensional vector spaces, every ordered basis induces a scalar coding of the
vectors where the scalars are from the base field. While finite dimensional vector spaces have
rich structures, graphs have only one structure namely adjacency. If a graph is connected, the
adjacency gives rise to a metric. This metric can be used to define a code for the vertices.

Since childhood I got accustomed to study with a pen in my hand.
I extracted theorems and formulas, together with the definitions, from my textbooks.
It was easier, later, for me, to prepare for the tests, especially for the final exams at the end of each semester.
I kept (and still do today) small notebooks where I collected not only mathematical but any idea I read from various domains.
These two volumes reflect my 1973-1974 high school studies in mathematics at the Pedagogical High School of Rm. Vâlcea, Romania.
Besides the textbooks I added information I collected from various mathematical books of solved problems I was studying at that time.
The first volume contains: Arithmetic, Plane Geometry, and Space Geometry.

Since childhood I got accustomed to study with a pen in my hand.
I extracted theorems and formulas, together with the definitions, from my textbooks.
It was easier, later, for me, to prepare for the tests, especially for the final exams at the end of each semester.
I kept (and still do today) small notebooks where I collected not only mathematical but any idea I read from various domains.
These two volumes reflect my 1973-1974 high school studies in mathematics at the Pedagogical High School of Rm. Vâlcea, Romania.
Besides the textbooks I added information I collected from various mathematical books of solved problems I was studying at that time.
The second volume contains: Algebra (9th to 12th grades), and Trigonometry.
