1: Comparative Analysis of Weighted Round Robin and Fair Queuing Scheduling Algorithms for the Quality of Service Assurance using Transmission Control Protocol (TCP) as Traffic Agents
This paper presents comparative analysis of scheduling algorithms: Weighted Round Robin and Fair Queuing using throughput, fairness rate, loss rate and delay as performance metrics for quality of service assurance. This work designed a topology to implement the two scheduling algorithms using Network Simulator-2 (NS-2) installed in a Linux operating system. Thirteen nodes were created for the topology to represent the eight sources, three edge routers, one core router and one destination. The simulations were run several times to arrive at the results. Based on the simulation results, it was observed that in terms of the three out of the four performance metrics: Throughput, Fairness Rate and Loss Rate; Weighted Round Robin scheduling algorithm was better than fair queuing scheduling algorithm in the internet using transmission control protocol (TCP) as traffic agent but reverse was the case in terms of delay as performance metric.

2: Exploring the Web Application Frameworks Using Orchard Core - A Case Study
This paper aims to explore the web application frameworks including their importance in web development. With the emergence of modern web development technologies and related web application frameworks, many web developers started using them because they have many advantages, such as modularity, security, productivity and much more. Although such frameworks are complex and required a learning curve, but they are very handy for developing of medium and large applications. In this paper, Orchard Core has been chosen as a case study to illustrate the web application framework features.

3: Electrochemical Sensors and Determination for Heavy Metal by
Rotating Disk Platinum Electrode and Chronoamperometric Method
Pollution by heavy metals is one of the most severe environmental issues that threaten global sustainability. This review presents a recent advance in electrochemical sensors for heavy metal detection Rotating Disk Platinum Electrode are discussed. This study on the production of a modern natural water electrochemical antimony (II) and cupper (II) test include the use of platinum electrode. Antimony and cupper were pre-concentrated on the modified electrode surface and adsorbed to the surface, oxidizing at E = 540 mV and E = 85 mV, respectively. After 20 min of accumulation, time the best-defined anodic peak was obtained of surface. The precision was tested by carrying out chronoamperometric measurements at a concentration of Sb+2 and Cu+2 8.5x10-8 M and 9.5x10-7 M, respectively.

4: Photons Shower to Disinfect Raw Nourishment before Gasp
Treating the raw fruit and vegetable with UV to visible energy photon before eating, kill external bacteria and virus attached on the surface of fruit and vegetable. This technology help to make eatable goods free from bacteria, virus, and germs without any side effect on fruits and the person who consume them. Numbers of pesticide, germicide, insecticide etc. are used to kill these bacteria, virus and germs but these are the chemical with affect our health both directly and indirectly. They also cause physical and chemical change in fruits or vegetables that they treat, but such change is not take place on treating fruits or vegetable with photons energy UV to visible.
Keywords: Raw Fruit, Bacteria, Virus, UV, Photons etc.
5: Data Hiding Enhancement in Arabic Text
Recently, information security has become a very important topic for researchers as well as military and government officials. For secure communication, it is necessary to develop novel ways to hide information, for this purpose, steganography is usually used to send secret information to their destination using different techniques. The aim of this article is to provide a new text steganography method. Hidden information in text files is difficult to discover as text data has low redundancy in comparison to other mediums of steganography. Hence, we use an Arabic text to hide secret information using a combination of Unicode character's zero-width-character (ZWC), zero-width-joiner (ZWJ) and pseudo-space (PS) in the proposed algorithm. The experimental results show increasing in hidden data capacity per word in comparison to the recently proposed algorithms. The major advantage of our proposed algorithm over previous researches is the high visual similarity in both cover and stego-text that can reduce the attention of intruders.

6: Solving Fuzzy Fractional Nuclear Decay Equations by the Residual Power Series
This paper deals with the solutions of fuzzy fractional nuclear decay equations (FNDEs) under Caputo H differentiability by Residual Power Series (RPS). The equations was reformulated under the influence of fuzzy logic. The Residual Power Series has been applied in solving differential equations with fuzzy initial conditions. This method is illustrated by solving two examples. The solution method has shown high efficiency and accuracy in the case of comparison with the exact solution and another method.
