Artificial neural networks for voice activity detection Technology

Currently, the direction of voice biometrics is actively developing, which includes two related tasks of recognizing the speaker by voice: the verification task, which consists in determining the speaker's personality, and the identification task, which is responsible for checking the belonging of the phonogram to a particular speaker. An open question remains related to improving the quality of the verification identification algorithms in real conditions and reducing the probability of error. In this work study Voice activity detection algorithm is proposed, which is a modification of the algorithm based on pitch statistics; VAD is investigated as a component of a speaker recognition system by voice, and therefore the main purpose of its work is to improve the quality of the system as a whole. On the example of the proposed modification of the VAD algorithm and the energy-based VAD algorithm, the analysis of the influence of the choice on the quality of the speaker recognition system is carried out.

Solid wastes management, Biogas and compost generated from organic waste at Al-Akaider landfill in Jordan

Jordan has been facing a wide variety of sudden changes in humanitarian issues (population growth, industrialization rapid, urbanization process, influx of refugees to Jordan etc.). These unexpected changes forced people to make quick reactions to adapt and settle, which resulted in further generation of solid waste which normally was dumped in landfills and caused contamination of soil, water and air. Solid Waste Management (SWM) has been an integral part of every human society. Improper SWM accelerates natural resources degradation and has a great impact on climate change and the quality of life of citizens. Hence, in this paper, we highlight the environmental and health problems of the Al-Akaider landfill in Jordan. We propose a multi-pronged integrated approach to improve solid waste management at the Al Ekaider landfill. In keeping with this approach, a general action plan has been proposed that could be tailored to recycle Organic Waste (OW) to produce biogas and compost. © 2018 JASET, International Scholars and Researchers Association

Semiconductors between past and present

There is no doubt that the semiconductor contributed very significantly to changing our world in the long run, which made it very necessary to write this article and shed light on the semiconductor between past and present. Whereas, this article is not intended to teach you semiconductor chemistry and its applications, but it also aims to refresh your memory with everything related to semiconductors from the moment of sunrise to the present day.As known, people need to communicate with each other in order to meet their daily and professional needs. In the past, the communication process was very difficult and sometimes costly until the emergence of what is known as semiconductors, which in turn opened new purview in the world of communications through its entry into the communication devices industry and computers industry and its ability to processing The data, in turn, facilitated and summarized a very long journey on humans in the field of industry. Today, we are on the beginning of a new sun rise of semiconductor, especially after the emergence of the so-called nanotechnology, where semiconductors have been observed a very large role in the development of this technology, not only but have become Part of the integral ones.

Information and communication technology (ICT) in education of comprehensive Methodological foundations and concept

This paper Information and communication technology (ICT) in education of comprehensive Methodological foundations and concept ,fills two major civilizational functions of personality development: its spiritual, moral, artistic, cultural development and its socialization, as well as the economic function, the reproduction of skilled labor resources for social production. The intensification of the process of obtaining knowledge, the requirements for quality and individualization of the process of obtaining education by different categories of students cause an urgent need to develop and implement a wide range of educational programs that allow everyone who wants to get that education, at the time and place that seem most acceptable to him, regardless of gender, age, social origin and abilities. On the study of the role of education in this context, inclusive pedagogy is aimed.

Investigation on Glucose and levels of Zn and Cu in Sera of Iraqi Males addicted on Methamphetamine or Tramadol

Addiction is the most critical form of Addiction. It is a chronic disease with a potential for fatality if not treated. In this work, 180 samples of male individuals were collected in this study. They classified into three groups, groups: G1 who were healthy control; G2 who was addicted to methamphetamine (meth); G3 who was addicted to tramadol (Tra). Each group consists of 60 heavy smokers Iraqi male individuals in the age range of 18-43 years. The results showed a highly significant increase (p<0.0001) in the level of Glucose of the two addicted groups in comparison with the healthy group. A highly significant decrease (p<0.0001) could be seen in the level of Zn of the two addicted groups G2, G3 compared to the control group, while the level of Cu of the two addicted groups were highly significant increased (p<0.0001). Also, the results showed a highly significant difference (p<0.0001) in BMI for the studied groups, G2, G3 in comparison with the control group. All addictive individuals under this study were at normal weight depending on their BMI.

Shear strength characteristics of Jerash expansive soil

The results of the direct shear test on Jerash expansive soil show the effect of the initial water content on the cohesion (c) and on the angel of internal friction ( ) [shear strength parameters].it show that, as the initial water increase, the cohesion (c) of Jerash expansive soil also increase up to the shrinkage limit, after that increase of water even small amount, decrease the cohesion of the soil.

Building Information Modelling Technology in Mitigating Cost Overruns and change orders in Construction Projects

Variation order (VO) is one of the main issues faced by the construction industry in Jordan. Many researchers had investigated on the causes of VO and proposed procedures to minimize and control this issue; however, the VO is affecting the construction industry badly even at moment. Building Information Modeling (BIM) is a powerful management system that can make a significant difference in the project costs. However, BIM has not been examined as a tool to minimize the VO in Jordan. The main target of this study is to utilize BIM applications in reducing the effect of VO on the governmental projects in Jordan. In order to achieve this target, the researcher has designed a questionnaire to gather data related to VO causes and the BIM capability to solve this problem. The data collected from the questionnaires were analyzed statistically. The result from the analysis found that the consultant initiated the highest VO of 50% followed by the clients and the contractors of 20% and 10% unforeseen variation respectively. Moreover, it is found that BIM Design Applications, Facility Operations Simulation, Exploration Design Scenarios, BIM Design Detection and BIM Quantity Take-off and Cost Estimation were significantly capable of minimizing VO. The results show positive relationship with the application of BIM in minimizing VO in the construction industry in Jordan. © 2018. JASET, International Scholars and Researchers Association
