Binary Encoding Differential Evolution for Combinatorial Optimization Problems
Статья научная
Differential Evolution algorithm is a new competitive heuristic optimization algorithm in the continuous field. The operators in the original Differential Evolution are simple; however, these operators make it impossible to use the Differential Evolution in the binary space directly. Based on the analysis of problems led by the mutation operator of the original Differential Evolution in the binary space, a new mutation operator was proposed to enable this optimization technique can be used in binary space. The new mutation operator, which is called semi-probability mutation operator, is a combination of the original mutation operator and a new probability-based defined operator. Initial experimental results of two different combinatorial optimization problems show its effectiveness and validity.

Blockchain Based Secure Traffic Police Assistant System
Статья научная
There are large numbers of vehicles in the populated country like India. It’s a very common scenario that traffic police came across some vehicle random vehicle and had some doubt in mind but do not have in hand information about that vehicle and end up leaving that thought. Sometimes this may result in some disaster. With the advent of technology, there are mobile applications and web based systems are available to ease up the process by which traffic police can fine the vehicle owner or people can pay the fine online. But yet there is no system is available through which traffic police can get all the details about the particular vehicle. This motivated us to design and developed an application thorough which traffic police can get all the information right from owner of the vehicle to its RC book and insurance status on just one click. Looking at the chances of data tampering, we have also played an attention to the data security and used blockchain for creating distributed, robust and tempered proof system. In this paper we have discussed traffic police assistance system, which can scan the vehicle number plate, identify the number and provide the all the information and documents stored against that vehicle number. To address the issue of data security and alteration of sensitive data blockchain is used so that any alteration can be monitored. As the complete information process is dependent on how correctly the vehicle number is identified, so the number plate recognition module is tested thoroughly under various conditions. Finally user feedback is taken and analyzed to evaluate the feasibility and usability of the proposed application.

Bruteporter: a hybrid approach
Статья научная
Stemming fetches the main root word from the inflectional words called stem. Stem gives different meaning when suffix or prefix is added to it. The stem need not give perfect meaning. Lemmatization gives lemma from inflectional words. Lemma should give meaning that in the dictionary form. Natural Language processing, Information retrieval, Text mining are the areas which use the stemming as preprocessing step. Through stemming, the size of the document can be reduced and ambiguity is also removed. It makes the work easy for other process likes information retrieval, semantic analysis, text categorization etc. Though there is a need for linguistic improvements in the existing stemming algorithms, all these algorithms fail in some cases to give an exact Root word and are not able to handle informal verbs. Hence, Bruteporter Hybrid approach is proposed in order to improve the linguistic process of stemming in English Texts. It combines the Wordnet and Modified Porter Algorithm. A Wordnet is a lexical dictionary created by linguistics people. Modified porter algorithm has both suffix removal and suffix substitution functionality. This proposed approach can extract root word from both inflectional words and informal verbs. In this paper, Experiment is conducted on proposed algorithm and the accuracy is calculated.

Change Impact Identification in Object-Oriented System: Dependence Graph Approach
Статья научная
The development of software products consumes a lot of time and resources. On the other hand, these development costs are lower than maintenance costs, which represent a major concern, specially, for systems designed with recent technologies. Systems modification should be taken rigorously, and change effects must be considered. The need to offer tools allowing on the one hand, to explain the mechanisms of changes at the source code level, and on the other hand, to reduce the effort as well as the cost of maintenance, is affirmed more and more. We propose in this article an approach based on dependence graph to identify change impact of object-oriented systems. The analysis of change ripple effect is made on the dependence graph representing the considered system. The identification at graph level of maximum range of change ripple effect will enable us to know consequences change at code source of system. This knowledge will enable us to estimate the change cost and to make a compromise between the various suggested changes. Finally, to concretize this study we produced a tool and tested our approach on certain systems.

Classification of Coronary Artery Disease Using Different Machine Learning Algorithms
Статья научная
Coronary Artery Disease (CAD) takes place in the category of fatal diseases resulting in death in our country and around the world. Each year about 340 thousand patients lost their lives due to CAD in Turkey. Early diagnosis is essential to reduce risk and prolong lifetime of these patients for diseases that require long-term treatment having death risk like CAD. For this reason, classification of CAD by using medical data processing and machine learning algorithms are important in order to develop assistive or expert systems for physicians. In this study, five different machine learning algorithms were applied to estimate whether patients in the Z-Alizadeh Sani data set extracted from the UCI machine learning pool are CAD. Accuracy, precision, recall, specificity and F1 score were compared as classification performance indicators to evaluate decision tree, random forest (RF), support vector machines (SVM), nearest neighborhood (k-NN) and multi-layer sensor (MLP) methods. According to the evaluation results, the MLP method gave high classification accuracy with 90%. It also appears that RF performs relatively better than other metrics. This results, show that these classification algorithms can be use for helping healthcare systems.

Classroom Management Strategies and Academic Performance of Junior High School Students
Статья научная
The study examined the influence of classroom management strategies of Junior High School teachers on the academic performance of students in the Ashanti Akim North District. The descriptive survey design was used for the study. One hypothesis and two research questions were developed to guide the study. Multistage sampling technique was used to select 48 teachers and 297 year two students to respond to the Behaviour and Instructional Management Scale (BIMS). Test scores in English Language, Integrated Science, Mathematics and Social Studies were used to measure students’ academic performance. The statistical tools used to analyse the data collected were means, standard deviation, Pearson’s Product Moment Correlation Coefficient (PPMCC) and Multiple Regression. The findings revealed that both students and teachers identified good relationship and reinforcement as the mostly used classroom management strategies. It was found that a significant positive relationship existed between reinforcement and antecedent as classroom management schemes and students’ academic performance. However, good relationship and punishment as classroom management strategies did not have a positive relationship with the academic performance of students. It is recommended that teachers should use reinforcement and antecedent strategies frequently in their classrooms since they play a dual role of managing behaviour and predicting the academic performance of students. Good relationship as a classroom management strategy should be cautiously used because it could potentially be misinterpreted or abused and can lead to low academic performance. Using punishment as a classroom management strategy should be avoided as its use hinders academic performance of students.
