Hypothesis on Different Data Mining AlgorithmsIJERA Editor
In this paper, different classification algorithms for data mining are discussed. Data Mining is about
explaining the past & predicting the future by means of data analysis. Classification is a task of data mining,
which categories data based on numerical or categorical variables. To classify the data many algorithms are
proposed, out of them five algorithms are comparatively studied for data mining through classification. There are
four different classification approaches namely Frequency Table, Covariance Matrix, Similarity Functions &
Others. As work for research on classification methods, algorithms like Naive Bayesian, K Nearest Neighbors,
Decision Tree, Artificial Neural Network & Support Vector Machine are studied & examined using benchmark
datasets like Iris & Lung Cancer.
because Ruby and Objective-C has the same ancestor, they have many things in common, and in this talk I mainly talk about what I learned in Ruby, borrow those experiences and move to Objective-C :)

Synthesis, Characterization and Electrical Properties of Polyaniline Doped wi...IJERA Editor
The polyaniline were prepared by using different inorganic and organic acids via oxidative polymerization
method. The prepared samples were characterized by FTIR, the peaks are found to be at 507 cm˗1, 592 cm˗1, 798
cm˗1, 1138 cm˗1, 1244 cm˗1, 1302 cm˗1, 1471 cm˗1 and 1556 cm˗1. These predominant peaks may be
confirming the formation of polyaniline. The structural analysis was studied by employing XRD; found that
polyaniline is amorphous in nature. The SEM studies reveal that they are agglomerated, irregular and size of
these grain increases with increasing amount of polyaniline with different organic and inorganic acids. The dc
conductivity (dc) as a function of temperature (T) for polyaniline is studied in the temperature range from 30 to
1600C. At higher temperature it is found that conductivity increases because of hopping of polarons from one
localized states to another localized states. The ac conductivity of polyaniline was prepared by oxalic acid show
high conductivity at 106 Hz. This is due to the space charge polarization and electrode polarizations.
Implementation of RTOS on STM32F4 Microcontroller to Control Parallel Boost f...IJERA Editor
The DC-DC converter is operated with pulse width modulation (PWM) and controlled by modifying duty cycle.
The PWM is easy developed on microcontroller system, but the problem become complex when some control
algorithm implemented to determine duty cycle value. Multitasking is needed to handle sensor, control algorithm
and user interface system. This paper discusses the application of Real Time Operating System (RTOS) to
handle multitasking process on STM32F407 ARM Cortex M4 microcontroller to control parallel boost converter
with load sharing algorithm for photovoltaic (PV) battery charging application. The first OS task is to run MPPT
to get maximum energy from PV. This first OS task is implemented to control the first boost converter. Then,
The second OS task to run fuzzy logic controller to control battery charging current with load sharing energy.
This second OS task is task implemented to control second boost converter. The measurement of current and
voltage of both converter side, display and user interface system also handled with OS task. As the result, each
designed task could run well with recommended OS task priority for MPPT and Fuzzy is IRQ task and for
TFT_LCD_displayosPriorityAboveNormal.
An Efficient and Optimal Systems For Medical & Industries With Concept of IOTIJERA Editor
Its quit interesting to starts with some philosophical manner rather than the aim of paper, that is, human kind
likes more and more simplified life in their daily activities. The people like, simplification in cooking, travel,
education, fashion design, dressing, information availability about certain things, communication from one place
to another and so on. That means, the people like intelligent automated life. In contrast artificial things can
interact with the human kind and solves their desires. For example, someone may have lost something,
somewhere, but they forget where they lost. The difficulty here is, how find the thing, someone may give the
solutions RFID technology but it works in certain range. So from the discussions, we need, the autonomous
mechanism, that can trace out the locality or information regarding to what we lost? In simple manner, we need
a common platform to integrate entire world of thing. For a little while, the common platform is internet and
hence we labeled Internet of Things(IoT). That’s what, the paper is going to deal. So the principal objective is to
monitoring the thing of parameters from anywhere in the world. The paper is not aimed to integrate entire world
of things right now but dedicated to two fields, medical & small, medium enterprises. In medical field, monitor
the patient through camera interface and patient’s moments using WSN interface. And in case of SM Enterprises
monitors, temperature, water level, machine motion detection using WSN and visual through Camera Interface.
The paper is built with high speed and low cost Raspberry-Pi Controller
FLC-Based DTC Scheme for a New Approach of Two-Leg VSI Fed Induction MotorIJERA Editor
A new Direct Torque Control (DTC) strategy for Induction Motor (IM) drive fed by a two leg three phase
inverter (i.e., Four switches are used in VSI) was proposed in this paper. The proposed methodology is based on
the emulation of operation of the conventional Six-switch three phase inverter. The combination of four
unbalanced voltage vectors is generated by the two-leg three phase inverter, approaching to the synthesis of the
six balanced voltage vectors of the conventional DTC. This approach has been implemented in the design of the
vector selection table of the proposed DTC strategy. Further, Fuzzy Logic Controller (FLC) is proposed in the
speed controller for the improvement of torque ripples. Convention DTC with Six Switch three phase VSI, twoleg
three phase VSI with PI and Fuzzy Controller are implemented using MATLAB/SIMULINK. Simulation
results have shown that the proposed DTC strategy, two-leg inverter fed IM drive revealed an improved
performance.
Interference Minimization Protocol in Heterogeneous Wireless Sensor Network f...IJERA Editor
High-quality data transmission is the primary objective of WSN for achieving quality of service.
Heterogeneous wireless sensor networks (HTWSN) can be used to deploy in sensitive and unmanned areas
to monitor the objects. HTWSN is high configured network used to capture high-quality images and videos
of targeted objects. During the data transmission in HTWSN, we identified that, the formation of
interference with in the network due to link capacity overhead. Due to that, the quality data transmission is
not possible through the network. In this research paper, we described the deployment of HTWSN network
and identifying the primary sources for interference and introducing the proposed Interference
Minimization Protocol (IMP). The IM protocol has achieved better quality of service by minimizing the
interference in HTWSN.
A study on Quality Attributes of Ghee based on packaging materials and storag...IJERA Editor
Glass ,Polyethyleneterephthalate(PET), Polypropylene (PP) and High density Polyethylene(HDPE) bottles were
filled with ghee, prepared by differently treated cream, under light with little headspace to determine the effects
of light ,method of preparation, packaging materials and storage time on the stability of ghee. The moisture
content, acid value, peroxide value, refractive index and TBA Value were measured to determine the stability of
ghee every 30 days of storage period.. Glass bottles recorded lower oxidation values followed by ghee packed in
PET, PP and HDPE. In few cases, PET packaged ghee also showed comparable good results. This study showed
that packaging material, method of preparation and storage time has an effect on the stability of ghee.
How was Mathematics taught in the Arab-Islamic Civilization? – Part 1: The Pe...IJERA Editor
No matter how societies have differed throughout history in their values, cultures, politics and systems of life,
there has always been a common consensus regarding the importance of mathematics and its role in the social
life. Arab-Islamic civilisation -like many others- had a reasonable command of many aspects of mathematics.
This was apparent in various applications including not just in everyday life, civil and business transactions, and
financial dealings, but also in certain religious rituals.
This paper aims to highlight the important position that the scholars in the Muslim East and West attributed to
mathematics, both in terms of teaching and practice. Furthermore, this work investigates the methodology of
teaching fractions in the Arab-Islamic society. The latter is found to be one of the mathematical subjects that has
been recommended to be taught to learners at their earliest learning stages, especially given the importance of
fractions in everyday transactions such as calculating shares of a legacy. The paper also examines some of the
educational requirements such as the teacher duties, student‟s qualities, education stages and what the relevant
curriculum recommended by scholars during each stage. Finally, this work briefly highlights one of the
contemporary issues which is the difficulty of teaching fractions for young learners and how this was addressed
in the past by one of the early Muslim Arab mathematicians through the use of simple poetry.
Presentación sobre el bullying, los actores y consecuencias. Características del acosador, de la víctima y del observador. Medidas de prevención en casa, la escuela y por el alumno.
2. ¿QUÉ ES EL BULLYNG?
• Es un comportamiento que se caracteriza básicamente
por maltratar, humillar y agredir física o
psíquicamente a un compañero. Así como también
burlarse de él, ignorarlo, asustarlo y dejarlo de lado
sistemáticamente.
• La principal característica de esta conducta es que
suele prolongarse en el tiempo y va dirigida a una única
persona (compañero o compañera) con el único objetivo
de dañarla.
3. ¿CUÁLES SON LAS CARACTERÍSTICAS DE UN
NIÑO QUE HOSTIGA A LOS DEMÁS?
• Por lo general le cuesta reconocer un error.
• No puede ponerse en el lugar del otro con
facilidad.
• Le cuesta pedir disculpas y reparar una conducta
considerada inapropiada.
• Es rebelde e inquieto y le cuesta adaptarse a las
normas de convivencia.
• No acepta los límites con facilidad.
• Tiene reacciones impulsivas.
• Es autoritario y agresivo de palabra.
• Suele tener mal comportamiento escolar.
• Molesta y desvaloriza a sus compañeros en clase
4. RAZONES POR LAS CUALES ALGUNOS
CHICOS ACOSAN A LOS DEMÁS.
• Los chicos normalmente acosan a los demás como una
manera de sentirse importantes y reconocidos. Y lo
disfrutan especialmente cuando descubren que el niño
hostigado no puede alejarse o defenderse de la
situación de maltrato.
• Pero también lo hacen por celos y rencor, para
llamar la atención, porque han sido acosados
por otros pasivamente y para ejercer su rol
de dominador-sometedor y sentirse
poderosos, normalmente producto de una
vulnerabilidad encubierta (se sienten menos
que los demás y el hecho de hostigar a otro
logra ocultar ese sentimiento).
5. • Cuando se produce una situación de acoso entre compañeros
de clase algo en el maestro suele fallar. No se puede perder de
vista a los niños. Es muy importante mantenerse en alerta y
pensar qué es lo que podemos hacer cuando descubrimos que
un niño está siendo acosado por otro. Siempre es importante
intervenir
6. ¿CÓMO NOS DAMOS CUENTA DE QUE UN
NIÑO ESTÁ PADECIENDO ACOSO ESCOLAR?
• No quieren ir a la escuela.
• Disminuye su concentración y desempeño
escolar y en algunos casos incluso repiten el
año.
• Se muestran temerosos e inseguros.
• Están tristes, se aíslan y sufren episodios de
ira y enojo.
• Se muestran irritables.
• Presentan dolores de barriga y cabeza.
• Tienen dificultades para dormir (pesadillas y
miedos).
7. • Presentan retraimiento y falta de comunicación
familiar.
• Se quejan reiteradamente.
• No quieren salir de casa o realizar actividades
que antes disfrutaban.
• Se vuelven agresivos con sus hermanos.
• Se aíslan de sus amigos.
• Se hacen del baño.
• Comienzan a mostrar trastornos de alimentación.
8. ¿CÓMO PODEMOS EVITARLO?
Podemos atajarlo con las siguientes medidas:
• Trabajando con los niños favoreciendo la resolución de
problemas a través de la palabra y la participación de
todos por igual.
• Respetando las diferencias y no tomándolas como
deficiencias.
• Generando situaciones de cooperación y solidaridad con
proyectos concretos.
• Hablando del tema del acoso sin ocultarlo.
• Capacitando a todos los integrantes de la comunidad
educativa para detectar el acoso.
9. • Creando un código de convivencia con reglas claras.
• Haciendo partícipes a los padres de estas acciones.
• Nadie debe padecer el acoso de un compañero ni es
merecedor de ello.
• Si los padres detectan que su hijo padece acoso o si
éste se lo cuenta es importante pedir ayuda en la
institución escolar para proteger al niño escuchándolo
y respetando su deseo de cómo quiere que se maneje la
situación sin exponerlo. Y por encima de todo, hay que
saber mantener la calma.
