 Abstract

Social network sites involve billions of users around the world wide. User interactions with these social sites, like twitter have a tremendous and occasionally undesirable impact implications for daily life. The major social networking sites have become a target platform for spammers to disperse a large amount of irrelevant and harmful information. Twitter, it has become one of the most extravagant platforms of all time and, most popular microblogging services which is generally used to share unreasonable amount of spam. Fake users send unwanted tweets to users to promote services or websites that do not only affect legitimate users, but also interrupt resource consumption. Furthermore, the possibility of expanding invalid information to users through false identities has increased, resulting in malicious content. Recently, the detection of spammers and the identification of fake users and fake tweets on Twitter has become an important area of research in online social networks (OSN). In this Paper, proposed the techniques used to detect spammers on Twitter. In addition, a taxonomy of Twitter spam detection approaches is presented which classifies techniques based on their ability to detect false content, URL-based, spam on trending issues. Twelve to Nineteen different features, including six recently defined functions and two redefined functions, identified to learn two machine supervised learning classifiers, in a real time data set that distinguish users and spammers.

 Abstract

In speaker Identification systems both parametric and nonparametric probability modeling is used. The Gaussian model is the basic parametric model that is used and this model is the basis of other sophisticated and it can be performed in a completely text independent situation. However, it sounds efficient to speaker identification application, but it results long time processing in practice. In this paper, we propose a decision function by using vector quantization (VQ) techniques to decrease the training model for GMM in order to reduce the processing time. In our proposed modeling, we take the superiority of VQ, which is simplicity computation to distinguish between male and female speaker. Then, GMM is applied into the subgroup of speaker to get the accuracy rates. Experimental result shows that our hybrid VQ/GMM method always yielded better improvements in accuracy and bring reduce in time processing. All the experiments have been done in both direct recording speech and mobile phone speech signals.

 Abstract

The experimental investigation is to know the behavior of rice husk cement partition board reinforced with Sisal Fiber which is effective in both cost and stability. Nowadays the major problems faced by the world is global warming. The use of such boards could be seen as partially solving the problem of global warming and the problem of pollution associated with the disposal of rice husks in developing countries. Instead of that need alternative material for without affecting the environment. In our investigation an attempt made to partial replacement of cement by rice husk and sisal fiber used to improve the strength of board. Results indicate that water absorption and thickness swelling decreased with an increase in fiber content and that there is an optimum rice husk / cement ratio and fiber content that gives maximum flexural strength and that such boards could be used in low cost housing construction. This study has deals with the ultimate strength of rice husk cement partition board reinforced with sisal fiber and influence of fiber content in board at various proportions of sisal fiber has been find out by conducting Compressive strength, Flexural strength, Water absorption tests, Drilling characteristics and Drop-down characteristics.

BACKGROUND: Neck circumference (NC) measurement is one of the simple screening measurements which can be used as an index of obesity. NC is a marker of upper body subcutaneous adipose tissue distribution. AIM: To correlate the neck circumference with body mass index and waist circumference and to determine the optimal cutoff value for neck circumference that define overweight/obesity. METHODS: Ethical approval has been obtained from Institutional Ethical Committee. The study comprised 100 medical students, aged 18-20 years. Anthropometric markers of obesity were measured, including body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (W-H ratio) and compared with neck circumference (NC) of the same subject. Pearson�s correlation coefficients were used to evaluate the associations of NC with BMI and WC. The optimal cutoff value for NC to identify overweight/obesity was determined by receiver operating characteristic (ROC) curves. RESULTS: The mean BMI (kg/m2) and WC (cm) were 22.38� 3.94 & 74.88�6.28 in boys and 21.17 �3.39 & 77.13 � 7.73 in girls, respectively. Mean NC (cm) in boys and girls were 31.37�1.88 and 31.61 � 1.88, respectively. There was no significant difference between genders for BMI, WC and NC. NC had a positive correlation with WC (r=0.67; p=0.000) and BMI (r=0.4, p=0.03) in boys as well as in girls (WC: r= 0.60, p=0.000, BMI: r=0.73, p=0.000). At BMI of 25 kg/m2 (overweight) and 30 kg/m2(obesity), boys had NC of 34cm & 35cm and WC of 81cm & 86cm compared to girls who had NC of 33cm & 34cm and WC of 84 & 94cm, respectively.

In Vietnam, the auditing profession was only born in about over 20 years and rapidly it became growing. In this overview, we highly reviewed techniques used for collecting audit evidences in financial audits, which is implemented by auditing companies including state, internal and independent audit firms. These techniques have been successfully applied in audit practices in many cases in Vietnam, but there is some limitation, which is necessary to be adjusted to some extent. In this overview, we also gave some recommendations for companies as well as audit industry to make use of in practices.

Floating school boats are one of the main means of getting primary education for the children of the Haor region in Bangladesh. However, the fundamental promise of a floating school boat is to provide free and accessible primary education to these severely flooded areas of Bangladesh. The purpose of this article is to find out the problems which are faced by the children of the waterlogged region of Bangladesh to get their elementary education. This study also explores that the contributions and initiates of one NGO are not enough to provide primary education for the children of this area. One the other hand, no significant initiative has been taken by the government of Bangladesh to educate them. So, the government of Bangladesh should take some reasonable steps to educate the children of this haor region. Currently, the Floating school boat education is a blessing for the children of these haor areas. This education system needs further improvement and progress by increasing the amount of floating school boats and drawing government attention as well as the proper distribution of the national budget.

 Abstract

This research worked is proposed for the Corona Virus COVID-19, the Core Area of this research is to study of Radiological results of the patient CoVID-19 in Pakistan and China, the CoVID-19 is Spreading very fast from person to person, this virus is a silent like a cold Bio-War and it were started from the Wuhan City of China. This virus has affected cases are 1,857,115 and deaths people are 144,332.we have research out that the previous virus is more dangers for the human that cause to death, but the CoVID-19 is not as much as danger for the death, it spread very fast from person to person, So we have study about X-rays image results show that COID-19 effect the human lunges and this virus attack on the lungs and human respiratory system, where it distress the respiratory system and its goes to down where patient can lost their life. From the x-rays images we have found that after the COVID-19 attacked on human its lungs system is completely damages and lungs are filed of water instead of the air. Human lungs properly not work to take the breath from nature they need to take the ventilator for the breathing.

Abstract�Augmented Reality commonly used on the E-Commerce web design to establish e-shopping and make it more interesting for Customers. Proposed system is an another approach of designing and creating Augmented reality for E-Commerce by using Omni-directional panoramic image. It create the Virtual Reality can be made by create 3D real time interaction environments to get as close as possible to the real world. To generate the 3D Virtual Reality, a high performance computer is needed. To view 3D Virtual Reality on e-Commerce web site also consume a large amount of Internet bandwidth. These problems will obstruct the chance of getting customers who can�t provide the high performance computer and high-speed Internet bandwidth. This paper proposes another approach of designing and creating Virtual Reality for e- Commerce web site by using omni-directional panoramic image. The panoramic image can be made by collect continuous images of the surrounding environment and combine them together. The omni-directional panoramic image can be used create the Image Base Virtual Reality (IBVR) which interacts with customer as expected in other Virtual Reality.

 Abstract

Respiratory muscle strength (RMS) is responsible for respiratory mechanics and is measured as MEP (Maximum expiratory pressure) and MIP (Maximum inspiratory pressure). Increment in MIP and MEP are probably due to deposition of fat around the chest making chest region stiff. The respiratory muscles in obese individuals are inefficient, and of low endurance. In undernourished, the lower absolute lean body mass leads to poor respiratory muscle strength and reduces lung functions. The cross-sectional comparative study was conducted on 40 healthy young individuals of age group 18-25 years. Initial assessment of the study group was done which included demographic data, height, weight, MIP, MEP (predicted). MEP and MIP (actual) was measured with the subject seated. For results unpaired t test was used and MIP values are extremely significant with p value of 0.0001 in underweight individuals and MIP values are very significant with p value of 0.0100 in obese individuals. This study concludes that the inspiratory muscle strength is reduced in underweight and obese healthy young individuals.
