Study of The ID3 and C4.5 Learning Algorithms

Abstract:

Data Mining is a process of exploring against large data to find patterns in decision-making. One of the techniques in decision-making is classification. Data classification is a form of data analysis used to extract models describing important data classes. There are many classification algorithms. Each classifier encompasses some algorithms in order to classify object into predefined classes. Decision Tree is one such important technique, which builds a tree structure by incrementally breaking down the datasets in smaller subsets. Decision Trees can be implemented by using popular algorithms such as ID3, C4.5 and CART etc. The present study considers ID3 and C4.5 algorithms to build a decision tree by using the “entropy” and “information gain” measures that are the basics components behind the construction of a classifier model 

Study of the Nanocomposite Mo2C(1-x)-TiC(x)-SWCNTs by Field Actived Sparck Plasma Sintering Process

Abstract:

Nanocomposites are worn resistant materials used in cutting tool applications. The materials are composed of ultrafine powder hard phase grains surrounded by a tough binder phase carbon nanotubes (Mo₂C)_1-x–(TiC)_x (2≤x≤4)//1Wt% SWCNTs. Composite bicarbide Mo₂C-TiC was rapidly synthesised and simultaneously consolidated by field activated sintering technique (spark plasma sintering) at which the extensive volume expansion occurred as a function of the volumic fraction from 20 to 40 vol.% of TiC powders and 1 Wt.% of SWCNTs was reinforcement of the NCMC’s. The sintered powder mixture was examined by XRD patterns, the morphology of the obtained phase was observed by SEM and the phase compositions in different regions were analyzed by EDX. The composites were processed using Field Activated Sintering Technique, spark plasma sintering (SPS) at temperatures in the range of 1700-1800°C with ...

Climate Migrant Elderly Abuse and Neglect: A Study in Slums of Dhaka, Bangladesh

Abstract:

Bangladesh many older people spend their life in not only the unwell health but also in poverty which is major risk for the elderly population. This is especially true for older women, who suffer from various difficulties ensuing from prejudices to gender, widowhood and old age. Climate migrants start living in urban slums are in search of better and secure life. But urban slums located mostly in low lying environmentally hazardous area coupled with inadequate facilities like food, shelter, sanitation, health care make their life even worse. Older Women are the vulnerable groups in society in terms of climate change, movement; haphazard growth and unhealthy environment are the target group for this research. This study represents the nature and extent of elderly abuse of climate migrant urban poor women slum dwellers in Dhaka city in Bangladesh context. Besides, this paper also observe the socio-economic status of the study respondents and try to find out the self...

Distribution Spread and Environmental Risk Status of Pb, Cd And Cr in Soils of an Open-Air Waste Dumpsite along Tombia/Amassoma Road in Yenagoa Metropolis

Abstract:

In spite of the popularity of open-air waste dumping in Nigeria, it remains a relatively less effective waste management option across the globe because of its associated environmental impacts which includes the release of green house gases (GHGs), persistent organic pollutants (POPs), and metal micro-pollutants amongst others. This study aims to assess the potential environmental risks associated to metals released and vertically delineated across the soil profile within surroundings of dumpsite. Heavy metals in soil samples were acid-digested using the aqua-regia mixture of hydrochloric and nitric acid, followed by instrumentation analysis using the GBC 908 PBMT model atomic absorption spectrophotometer. Contaminated sites showed metal concentrations ranging from 1.493 to 109.460 mg/kg, 0.133 to 4.237 mg/kg, and 5.200 to 25.367 mg/kg for lead, cadmium and chromium respectively, with location 1 land area showing the most contamination. Only soi...

Reasons for Increased Social Distancing and Surface Disinfection from a Physics Perspective

Abstract:

This viewpoint uses physical principles to explain mechanisms behind social distancing and surface disinfection. It links particle dynamics and contact transfer to practical guidance and risk communication during respiratory epidemics.

Using Human Development Indices to Identify Indicators to Monitor the Corona Virus Pandemic

Abstract:

The Corona virus (CoVID-19) pandemic has hit the most developed countries and has thence spread to inflict other countries around the world. It is the first pandemic that appears in countries not linked to poverty and poor hygiene.

The Migratory Phenomenon in Italy- Access to Health Services

Abstract:

This article describes access to health services among migrants in Italy, summarizing barriers, policy context, and recommendations to improve equitable care.

Assessment of Target Volume Definition for Radiosurgery of Atypical Meningiomas with Multimodality Imaging

Abstract:

Meningiomas are most common intracranial benign tumors comprising around one third of all intracranial neoplasms, and typically have benign and indolent nature with slow-growing behaviour. Benign meningiomas are slow growing tumors typically following an indolent disease course. Nevertheless, atypical or anaplastic meningiomas may follow a more aggressive disease course with invasion of critical structures and recurrences. In the current study, we evaluate the incorporation of magnetic resonance imaging (MRI) for radiosurgery treatment planning of atypical meningiomas.

The Hazards of Abdominal Obesity

Abstract:

Abdominal obesitywith a big belly is one of the worse type of morbid obesity that is associated with different health failure outcomes. Central obesity leads to an increased risk of health complications such as metabolic syndrome, hypertension, insulin resistance,type 2 diabetes, heart disease and various cancers. Abdominal obesity also can specifically cause to spinal nerve pain and backache. Depression and disability are other subsequent hazards of central fatness. More importantly ,excessive central body fat ultimately contributes in all-causes of early mortality. In regards to this, individuals with abdominal obesity is urgently needed to reduce central obesity using behavior modifications. Changes in diet and performing some exercise in everyday living are essential steps.
