Potato Leaf Disease Detection Using Image Processing
Статья научная
The economics of a nation is significantly influenced by agricultural productivity. Finding plant leaf disease is crucial since it significantly reduces agricultural productivity. Traditional detection methods like observing with the naked eye can lead to time-consuming and less accurate results. Farmers can’t always tell the difference between leaf diseases because sometimes they look the same. That’s why researchers have started using automation techniques to accurately detect the main diseases and their symptoms. This research proposed potato leaf disease detection using an image processing technique where the dataset was obtained online. In the proposed method, several image pre-processing techniques are used including data augmentation, gaussian smoothing, image normalization, dimensionality reduction and one hot encoding. CNN, KNN and SVC were used as classifiers. CNN gives the best result with an overall accuracy of 97%. Previous works with different classifiers had several limitations and using CNN the researchers didn’t get satisfying result. For this research a new hybrid model is introduced which can utilize the best of CNN classifier and it will be much more reliable and effective.

The study was aimed to create a predictive model for predicting students’ academic performance based on a neural network algorithm. This is because recently, educational data mining has become very helpful in decision making in an educational context and hence improving students’ academic outcomes. This study implemented a Neural Network algorithm as a data mining technique to extract knowledge patterns from student’s dataset consisting of 480 instances (students) with 16 attributes for each student. The classification metric used is accuracy as the model quality measurement. The accuracy result was below 60% when the Adam model optimizer was used. Although, after applying the Stochastic Gradient Descent optimizer and dropout technique, the accuracy increased to more than 75%. The final stable accuracy obtained was 76.8% which is a satisfactory result. This indicates that the suggested NN model can be reliable for prediction, especially in social science studies.

Diabetes has since become global pandemic – which must be diagnosed early enough if the patients are to survive a while longer. Traditional means of detection has its limitations and defects. The adoption of data mining tools and adaptation of machine intelligence is to yield an approach of predictive diagnosis that offers solution to task, which traditional means do not proffer low-cost-effective results. The significance thus, is to investigate data feats rippled with ambiguities and noise as well as simulate model tractability in order to yield a low-cost and robust solution. Thus, we explore a deep learning ensemble for detection of diabetes as a decision support. Model achieved a 95-percent accuracy, with a sensitivity of 0.98. It also agrees with other studies that age, obesity, environ-conditions and family relation to the first/second degrees are critical factors to be watched for type-I and type-II management. While, mothers with/without previous case of gestational diabetes is confirmed if there is: (a) history of babies with weight above 4.5kg at birth, (b) resistant to insulin showing polycystic ovary syndrome, and (c) have abnormal tolerance to insulin.

The purpose of the scientific article is to identify a possible solution to the problem of improving students’ training effectiveness through the combined usage of active forms and methods of teaching students among the dependent learning parameters set. The authors came to this hypothetical opinion based on the comparative analysis results of previous studies, which confirm that the usage of active forms and methods of teaching students is the right vector for solving the lifelong problem of learning improving the effectiveness. It has been established that the available psychological and pedagogical literature does not provide specific solutions for modern students - cyber-socialised youth, which would help to substantiate the best ways to intensify students' learning and cognitive activity. Previous scientific studies have confirmed that the group of people who are most addicted to computer games, as practice shows, is difficult to motivate to study using traditional approaches when there is a distracting and, to some extent, gambling factor. Based on these circumstances, the proposed research is obviously logical from the need to improve the theory and methodology of vocational education through the usage of active forms and methods of teaching students. New circumstances have determined the subject of the study, which is a professional business game. It has been experimentally determined that during a professional business game students will use simulation models to solve professional problems. To organise and conduct a professional business game, teachers define game and functional goals. In the above variant of the professional business game structural scheme, the goal of accelerating the discipline development through students' learning activation is achieved. Organising and conducting a professional business game as an active teaching method involves preparation of both students and teachers for it, and also requires the methodological materials and technical means availability, which helps to increase the classes effectiveness conducted in a game form and to form professional competencies in students. The article provides practical steps for preparing participants of a professional business game.

Proposal of Enhanced FDD Process Model
Статья научная
Feature driven development (FDD) is an agile process model that develops software according to the client features. The FDD consists of five processes, several practices and both are providing benefits to improve the software development. Although the FDD provides lots of benefits, but still endures many flaws. In previous research, there have been made numerous modifications in FDD with different aspects. These modifications could not fix all type of flaws and FDD requires improvements in many aspects. These flaws reduce the agility to deliver increments continuously and make an inverse relationship between quality and agility. Due to this relationship, the FDD does not utilize enough time on making extensive documentation, robust design, client or user involvement, and efficient testing. To overcome these issues, an enhanced feature driven development model is proposed. EFDD introduces best practice of agile manifesto named as behavioral driven development used in FDD. In this way, the focus on delivering increments quickly is achieved without affecting the quality of the software. The proposed model provides maximum agility with continuous delivery according to client features and efficient testing strategy which have asses every feature according to client specified functionality.

Proposal to Improve Mobility in Service Oriented Architecture
Статья научная
Service Oriented Architecture (SOA) is a standard to implement and design applications. It is a channel of communication between service consumer (SC) and service provider (SP). SP offers a service and SC uses a service. Mobile web service verifier component, of SOA architecture, matches best service that is called. Mobile web service verifier component finds a best match of particular service in SP if it is available by the SP. Therefore, there is a pressing need to develop a component that can create a service if it is not found by mobile web service verifier component. This problem is addressed by proposing a new component for SOA architecture called service upgrade (SU) to increase and improve the service creation speed and satisfy SC and SP needs. The questionnaire is used as a research design to evaluate the proposed solution by providing qualitative data. The results show that the majority of respondents are in favor of the proposed solution. It is anticipated that the proposed solution will cater the industrial problem in hand.

Proposed risk management model to handle changing requirements
Статья научная
The change in requirements while construction of a software may bring into several risks like over budget and extra schedule. The changes in requirements are considered as a high risk to fail the software projects. A good project manager always incorporates risk management paradigm to manage the risks of changing requirements. This research uses available statistical techniques to estimate the cost of risk management with respect to the changing requirement. In addition, a hybrid cost estimation model is proposed using action strategy model to counteract, mitigate and manage the risks of changing requirements. The proposed model is validated using an industrial case study in Saudi Electricity Company (SEC) to conclude the results. The results are found supportive because the proposed model shows significant improvement to estimate the costs of changing requirements as compared to the existing cost estimation models.

Protocols for Secure Internet of Things
Статья научная
Internet of Things has become a buzzword. It refers to networking of simplest mundane objects not just for human to machine or human to human interactions but for independent thing to thing interaction as well. Such interconnected or smart environment can do wonders but at the same time poses numerous threats to human lives. The ordinary and less powerful objects from day to day life are holding sensitive and private data from humans and trying to transport that through the insecure world of Internet. This new phase of Internet or Internet of Things (IoT) is yet in its infancy and does not have a security support mechanism of its own. The Internet and World Wide Web deal with interconnection of powerful devices like computers or smart phones and are well supported by standard Internet protocols ensuring optimum security and protection. The lightweight versions of the existing Internet protocols are backing the operations of IoT to a large extent but the security needs are not met completely as of yet. Many research organizations and individual researchers are working to make existing protocols and infrastructure applicable in IoT. This paper highlights the threats posed by uncontrolled proliferation of Internet of things and discusses major protocols that have been or that are being designed to overcome the security issues raised by Internet of things.

Статья научная
Search engine acts as an interface between users and computers. Online search is a very quick and impactful evolution of human experience. It is becoming a key technology that people rely on every day to get information about almost everything. Searching is typically performed with a common purpose underlying the query. If the user does not know the knowledge of the keywords to be searched, spends more time to frame the query. The search may not contain the user’s intended answers. Understanding the meaning of the query given by the user is the important role of the search engine. The query auto-completion feature is important for search engines. The query auto-completion process occurs uninterruptedly, dynamically listing terms with each click. It provides recommendations that facilitate query formulation and improve the relevancy of the search. Graphs and additional data structures are used frequently in computer science and related fields. The applications of graph machine learning include data recovery, friendship recommendation, and social networking. Heterogeneous graphs (HGs) consist of different kinds of nodes and links, and are useful for defining a wide range of complicated real-world systems a robust graph neural architecture for encoding a knowledge graph is the Relational Graph Convolutional Network (R-GCN).The proposed model uses the supervised Relational Graph Convolutional Network(R-GCN), Long Short-Term Memory (LSTM) for completion of the query. The model predicts the object given the subject and predicate and the accuracy is 92.4%.
