Coagulation-flocculation process remains a very essential part in the water treatment chain. It involves both physical and chemical phenomena and hence susceptible to high percentage of errors due to human factors. In order to reduce this percentage error and obtain optimal treatment efficiency, an intelligent coagulant dosing based on Artificial N

The present paper investigates the behavior of experimental polypropylene ternary nanocomposites produced in the laboratory under different process conditions using multiwall carbon nanotube as secondary filler. Full factorial experimental design was explored to study the effect of temperature, mixing speed and carbon nanotube (CNT) loading on the

In this paper, a method of defining the even-even deformed nuclei inertial parameters is suggested. Calculations for isotopes 162-168 Hf and 164-176 Yb are listed. The parameters of inertia of rotational nuclei are also defined. Dependence of the parameters of inertia on the nucleons number is shown. Dalam kertas ini, dicadangkan satu kaedah untuk

Digital information offers wonderful oppOltunities and improvements to human life, especially with the advent of internet. Such opportunities and improvements pose a great concern to all multimedia industries, especially intellectual properties. The fact is that the current digital distribution and storage technologies are great threat of counterfe

The requirement needed for an effective and proficient watermarking system is application dependent. However, robustness and image quality (imperceptibility) are fundamental requirements for applications that deal with image watermarking. The major factor that affects the robustness and imperceptibility is the watermark embedding strength. In this

In this paper, the development of guidance, navigation, and control algorithms of an autonomous space rendezvous and docking system are presented. These algorithms are based on using the analytical closed-form solution of the Tschauner-Hempel equations that is completely explicit in time. The navigation system uses an extended Kalman filter based o

In this paper, the development of relative navigation, guidance, and control algorithms of an autonomous space rendezvous and docking system are presented. These algorithms are based on using the analytical closed-form solution of the Tschauner-Hempel equations that is completely explicit in time. The navigation system uses an extended Kalman filte

In this paper, the dynamics of the relative motion problem in a perturbed orbital environment are exploited based on Gauss’ and Cowell’s variational equations. The inertial coordinate frame and relative coordinate frame (Hill frame) are studied to describe the relative motion. A linear high fidelity model is developed to describe the relative m

The use of transobturator tape (TOT) for the treatment of stress urinary incontinence (SUI) has gained popularity since it was introduced in 2001. Only few studies have reported that TOT is superior in safety and efficacy when compared to tension free vaginal tape (TVT). This case-series study was conducted to investigate the safety and efficacy of

Introduction: Frequency of lower urinary tract symptoms (LUTS) in young age women is not well studied. It is said to be common among female elderly and multiparous opulation. The aim of this study is to obtain the prevalence of LUTS among nulliparous students in relation to their personal hygiene. Materials and methods: This is a prospective cross-
