1: Electrochemical Analysis of Sulfamethoxazole by Differential pulse voltammograms Method


Manganese and Molybdenum oxides are well-known electro-catalysts in fuel cells systems; they are usually used as anodic materials for the oxidation of low molecular weight alcohols. The utilization of MoO2 and MnO2 as catalysts in the pharmaceutical analysis is not common yet an analytical method for the determination of Sulfamethoxazole (SMX) antibacterial agents in Pharmaceutical Dosage form is developed. The method is based on the voltammetric determination of SMX using modified glassy carbon electrode by molybdenum oxide. The two components are oxidized at the modified electrode surface with the development of current that is linearly proportional to their concentrations in the range of 7.04*10-7- 1*10-3 M for SMX. The oxidation reaction of the two components is pH-dependent, in which the buffer used is Britton-Robinson at pH = 7.00 where maximum peak current and maximum peak separation is obtained. The regression factors obtained from the calibration curves are 0.9790 for SMX and 0.9812 for TMP. The method of analysis was validated, where the limit of detection (LOD) and the limit of quantitation (LOQ) of SMX were calculated to be 1.44*10-4 M, 4.36*10-4 M and 1.27*10-4 M, 3.84*10-4 M respectively, The percentage recovery of both components was also calculated to 81 % for SMX.

Communication is the process human beings understand what is said to them and the way they say or express their thoughts, needs and feelings to other people and this is mostly through speech. Although, when it comes to people with hearing impairment, sign language is inevitable. Thus, sign language is the most natural and effective way for communicating among deaf and other people. This study reviewed various schemes in the application of AI in the recognition and interpretation of sign language for machine and human understanding. This study revealed that numerous researchers have proposed and implemented diverse computer and android based application to aid learning and teaching sign language while others developed numerous machine learning algorithms and frameworks to foster sign language recognition system. Thus, this study established that artificial intelligence has greatly developed the teaching, learning and communication with sign language and obviously, artificial intelligence will be capable to resolve the future challenges that may arise in that regards.

4: Techniques and Assessment of Lean Manufacturing Implementation: An Overview


Lean manufacturing is absolutely required for distinct industries to create a competitive industrial standard. Therefore, Lean manufacturing became a standard manufacturing mode of the 21st century. Lean manufacturing could have various corresponding synonyms for example lean management and Lean production. It implicates techniques and tools to minimize non value-added activities from the customer point of view. Waste (Muda) is a serious problem in the industry; it creates non value-added services and poor quality of the product. Waste has seven types which can totally or individually occur in the industry that are transport, inventory, motion, waiting, over-production, over-processing, and defect. Using lean tools and techniques all several wastes can be eliminated. Hence implementing the lean manufacturing system is becoming a core competency for any type of organization to sustain. This paper aims to conduct a quick review of Lean principles, the most commonly used Lean techniques, and Lean assessment.

6: Software Bug Prediction Using Static Analysis with Abstract Syntax Trees


Predicting software bugs in the early stage of the software development life cycle had some challenges, such as generating test data that had been used into the test, and exploring the method paths. This paper aims to explore the importance of using and applying abstract syntax trees (AST) with static program analysis in software testing to predict the software bugs that can be found to increase software quality and reduce the time required for discovering the software bugs and money cost by automating the unit tests. To achieve these goals, a new approach proposes to identify the potential bugs in the source code for the method under test by constructing an abstract syntax tree model for the method, then traversing the tree and exploring all paths to find the bugs. Hence, Smart Unit Tests are generated accurately to cover all possible executions paths for the tested method. At the end, the proposed approach uses static analysis, is able to predict all kinds of static bugs and generates the minimal suite of unit tests which are able to cover all the possible execution paths for the tested code. This indicates that the proposed approach achieves good results compared with other techniques regarding the type of bugs that can be predicted as well as the number of generated unit tests that are required to test the code.
