In this paper, a fully automated model is designed using deep learning algorithm to capture images from patients and pre-process, segment and classify the intensity of cancer spread. In the first pre-processing step, pectoral muscles are removed from the input images, which are then downsized. The removal of pectoral muscles after identification may become crucial in classification systems. Finally, the pectoral musclesaredeleted from the picture by using an area expanding segmentation. All mammograms are downsized to reduce processing time. Each stage of the fully automated model uses an optimisation approach to obtain highaccuracy results at respective stages. Simulation is conducted to test the efficacy of the model against state-of-art models, and the ...

Since flow of knowledge usually happens in a particular context, context has to be taken into consideration in knowledge flow modeling. Past models of flow of knowledge lacked in terms of software development and lacked in-depth exploration of context modeling, which made those models less applicable. This research proposes a conceptual framework of context oriented flow of knowledge in software development aspects. In this framework, the context is seen as an inseparable element of flow of knowledge, which is regarding the creation, transformation as well as application of knowledge items. Framework KFFD is proposed based on three aspects-flow of knowledge, software development project and ontology. For the proper use of knowledge, dynamic flow to destinations form sources is necessary. In this context, a new framework in KM is analyzing, designing and implementing know...

There are different definitions for this term, ranging from any system that has sensors and actuators to a solitary interconnected network of physical items. This Paper shows that this term does not give enough information to construct a software architecture on. This is accomplished by taking an inside look at the IoT described in literature as well as the types of applications that exist on the market today and using the concept of software architectural styles to show how different areas in the IoT will need varying styles. This paper continued to classify solutions in the Internet of Things into different classes. The outcomes are that for a subset of the classes there is a reasonable style, however for remaining classes there are still different decisions where more context information is needed.

In a knowledge-based organization, knowledge workers need to acquire a variety of knowledge (information) about their tasks .Therefore; many organizations have built knowledge support plat forms to assist workers in meeting their knowledge-needs. These platforms help workers to identify and share knowledge in order to speed up organization innovation and improve employee Productivity. The paper gives an over view of knowledge flow, type of knowledge flow, mechanical of knowledge flow, knowledge flow process. This review shows the description of Knowledge flow element and knowledge characteristic. This paper as systematic review of the knowledge flow. Choose the best way according to that.

It is an important concept in computer science to formally represent knowledge in a way that software can process the knowledge and reason about it. The software engineering ontology assists in defining information for the exchange of semantic project information frameworks. Research into ontological issues has been widely active in various areas. This paper presents the origin of ontology research and gives the different definitions of ontology. The paper provides an overview of ontology and its types including the building and design for an enterprise system. Finally the paper provides a systematic review of the subject.

The development of information technology has led many organizations to become more focused on knowledge than on labor because KF is considered complementary to the software development process when used in the software development domain. Knowledge is the most valuable property about any business organization or academic institution; in addition the knowledge flow plays a part in elevating the competitiveness of teams. This paper presents the origin of KF research and its different definitions. It provides an overview of KF and workflow and the interaction mechanism between the two. A systematic review of the subject is also given.

To further investigate the scope of the green software development process and its integration with information systems such as the Enterprise Resource Planning (ERP) system, we presented this study due to its importance in minimizing the negative effects of information technology on our natural environment. In this connection, there is a have to combine sustainability and information technology allow organizations to behave in a manner to going greener. Comprehending that the Enterprise Resource Planning (ERP) system is one of the very effective commercial enterprise solutions for organizations, it is necessary to align its use with sustainability factors through the utilization of green IT practices, the objective ...

This study proposes an optical challengeresponse user authentication system model based on the One Time Password (OTP) principle (Scan2Pass) that use multifactor authentication and leverage a camera equipped mobile phone of the legitimate user as a secure hardware token. The methodology which is designed and implemented to evaluate the proposed idea will be explored and explained throughout this paper. The chosen method presents a brief overview about the steps required to design an efficient and practical system. Also, the requirements will be discussed as well as our assumption to give a simple yet an adequate understanding about the security of our proposed system in general. Then, an overview about the basic architecture needed for the proposed system to explain the role of the shared secret and the challenge response protocol in order to complete aut...

Since flow of knowledge usually happens in a particular context, context has to be taken into consideration in knowledge flow modeling.

This research proposes a conceptual framework of context oriented flow of knowledge in software development aspects.

Framework KFFD is proposed based on three aspects-flow of knowledge, software development project and ontology. For the proper use of knowledge, dynamic flow to destinations form sources is necessary. In this context, a new framework in KM is analyzing, designing and implementing knowledge flow management systems. One crucial challenge in such systems is the exploration of flow of knowledge from its origin to the receiver. Another challenge is controlling the flow for quality enhancements regarding the requirements of the users. As such, the aim of this research is to provide a framework so as to solve this challenge. Keywords: knowledge flow, knowledge flow framework design, type of knowledge flow, knowledge flow management.

The aim of this paper is compare the effect of using two distributed algorithm which are Ant Colony as a Swarm Intelligence Algorithm and Genetic Algorithm. In Ant Colony Algorithm each individual ant constructs a part of the solution using an artificial pheromone, which reflects its experience accumulated while solving the problem, and heuristic information dependent on the problem. The results of comparison show that Ant Colony is high efficient than Genetic Algorithm and it requires less computational cost and generally only a few lines of code
