Factor Analysis and Survey Design

This paper analyzes factor analysis, discussing both confirmatory factor analysis (CFA) and exploratory factor analysis (EFA), as they relate to survey design. Shi et al. (2017) is discussed and compared to another study applying factor analysis by Tungkunanan (2020). A discussion of how factor analysis is used in my current field and potentially for COVID research is also explored. First, however, a discussion of the history of factor analysis, how it was designed, improved, and is currently...

Assess the Value of Hypothesis Testing

This paper discusses and analyzes the procedures of hypothesis testing, benefits, and detriments. 

Design and construction of bio-gas for household use

ABSTRACT: The designed air driven engine is an economic friendly engine which operates with the aid of a compressed air. in principle, an air driven engine uses the expansion of compressed air to drive the pistons of an engine. an bio gas driven engine is a pneumatic actuator that creates useful work by expanding compressed gas. there is no mixing of fuel with gas as there is no combustion. An gas driven engine makes use of compressed gas technology for its operation the compressed a...

Human Activity Recognition by Wearable Sensors

The purpose of this project is to develop a model that is capable of recognizing daily basic human activities under real-world conditions, using data collected by a waist-mounted triaxial accelerometer and gyroscope built into a cellphone (in our study, a Samsung Galaxy S II). Activity recognition is formulated as a supervised classification problem, whose data is obtained via an experiment having 30 human subjects perform each of the activities. Our classi...

Hypolipidemic Propensity of Ethanolic Extract of Xylopia

ABSTRACT  Aim:  This  study  is  aimed  at  assessing  the  effect  of  Xylopia  aethiopica  fruit  on  the  lipid  profile  of Wistar rats. Methodology: The fruits of Xylopia aethiopica were obtained from new market in Aba, Abia State, Nigeria  and  were  authenticated.  They  were  air-dried  and  extracted  using  Soxhlet  apparatus  and etha...

Weight Gain Reduction and Hypoglycemic Effects of Xylopi

ABSTRACT  Aim: This study  is aimed  at determining the effect of Xylopia  aethiopica  fruit on weight gain and blood sugar level of Wistar rats. Methodology: The fruits of Xylopia aethiopica were obtained from new market in Aba, Abia State, Nigeria  and  were  authenticated.  They  were  air-dried  and  extracted  using  Soxhlet  apparatus  and ethanol  as  solvent.  The  median  let...

Nephrotoxicity of Ethanol Extract of Xylopia aethiopica

  ABSTRACT  Background: The  use  of  Xylopia  aethiopica  fruit  in  folklore  medicine  is  on  the  increase  without regard to its toxicity. Aim: This study was aimed at examining its toxicity on the kidney of Wistar rats. Methodology:  The  fruits  of  Xylopia  aethiopica  were  air-dried  and  extracted  using  Soxhlet apparatus  and  ethanol  ...

Physicochemical and Phytochemical Analysis of Honey and Shea Butter Samples and Their Antibacterial Effect on Staphylococcus aureus AND Klebsiella pneumoniae

ABSTRACT This research work was carried out to examine the physicochemical and phytochemical constituents of honey and Shea butter samples respectively and their antibacterial effect on Staphylococcus aureus and Klebsiella pneumoniae. The physicochemical screening of honey showed that the honey samples used have low water activity, low moisture content, low pH value below 4.0 and Ash while the phytochemical analysis of Shea butter revealed the presence of Saponnins, Tannins, Alkaloid...

Geophysical Interpretation of Abakaliki And Bansara Area, Lower Benue Trough Nigeria Using Airborne Gravity Data

              ABSTRACTThe Geophysical Airborne gravity data of Abakaliki and Bansara area of Lower Benue Trough Nigeria was interpreted qualitative and quantitative in order to determine the sedimentary thickness/depth to basement and the possibility of hydrocarbons accumulation in the area and also to determine the density contrast and different rock types or rock bearing minerals present in the area. Source Parameter Imaging (SPI) and Forward and Inverse modeling techniques were empl...

Quality of Life Meets Metropolitan Ambitions

This paper examines how people in Copenhagen interact with and perceive six of the main neighbourhoods in the capital. As a special case, an equivalent analysis is carried out for the popular food market Torvehallerne. The research was conducted by applying statistical analysis and natural language processing to captions from Instagram posts tagged with neighbourhood names. The analysis reveals that the Instagram segment have a positive perception of their ...

Improving Text Classification using Deep Neural Networks and Word Embeddings

Natural Language Processing is a flourishing aspect of Data Science in both academia and industry. This paper examines the technique of sentiment classification on text data using automated Machine learning approaches. It will delve into newly introduced embedding techniques and machine learning model pipelines. The models explored in this paper consist of a simple Naive Bayes classifier, as well as several Deep Neural Models, including a Gated Recurrent...

An Overview of Polymers Used in Paint and Surface Coatings Application

An investigation was carried out to identify the different types of polymers used in paint and surface coatings and variations of the final products upon modifications of the materials used. The process of manufacturing paint and surface coatings involves a great deal of understanding various molecular behavior of paint and surface coatings polymeric matrix. These advance knowledge helps in developing new and advanced modifications of the super polymers. Every desire of a paint and surface co...

Design And Implementation Of Design Implementation Of A Cross Platform Database For Patients Medical Record

ABSTRACTElectronic Health Record systems (EHR) are increasingly being deployed within healthcare institutions to reduce the problems and limitations of the paper-based approach but its deployment has been slow due to high investment and maintenance cost. Cloud Computing has been widely recognized as the next generation’s computing infrastructure and it offers several advantages to its users. In this study, an Enterprise Electronic Cloud-Based Health Record System (E2CHRS) was desi...
