Integration of the tagging mechanism in the collaborative e-learning system

Abstract -

The tagging mechanism is a technique that can be used to implement the personalized collaboration in the e-Learning systems, thereby increasing the efficiency of such a system. Semantic Web technologies can be used to enhance tags with machine-readable annotations to improve the accuracy of tag-based recommendation services.

The novelty of the proposed approach is the combined use of the Semantic Web technologies and the reuse-oriented model in the development of the e-Learning environment.

Method for Balancing Energy through the Mobility of Node Agent in Mobile Sensor Network

Abstract

In the recent years, low power computing systems have gained popularity. Networks, which use low power computer systems and transmit data by using wireless connection, are called wireless sensor networks. Nowadays, the most topical studies are aimed at grouping wireless sensor networks by the new optimisation of structure of network transmission protocol, the routing optimisation in a transmission network, optimisation of network structure, as a result of which it is possible to increase the life cycle of wireless network sensors.

There are a number of methods that allow solving this problem. These include the choice of the capacity of individual battery, the deployment of the node density, the adjustment of power transmitter, the application of energy-efficient data transfer protocol, positioning of network nodes and other methods that are associated with the introduction of additional network costs.

The present article discusses a new method for balancing energy through the mobility of network node intellectual agent, which provides the opportunity for reconfiguration of dynamic network or change of network topology.

Security Process Capability Model Based on ISO/IEC 15504 Conformant Enterprise SPICE

Abstract

In the context of modern information systems, security has become one of the most critical quality attributes. The purpose of this paper is to address the problem of quality of information security. An approach to solve this problem is based on the main assumption that security is a process oriented activity. According to this approach, product quality can be achieved by means of process quality - process capability. Introduced in the paper, SPICE conformant information security process capability model is based on process capability modeling elaborated by world-wide software engineering community during the last 25 years, namely ISO/IEC 15504 that defines the capability dimension and the requirements for process definition and domain independent integrated model for enterprise-wide assessment and Enterprise SPICE improvement

Introduction to Lean Canvas Transformation Models and Metrics in Software Testing

Abstract

Software plays a key role nowadays in all fields, from simple up to cutting-edge technologies and most of technology devices now work on software. Software development verification and validation have become very important to produce the high quality software according to business stakeholder requirements. Different software development methodologies have given a new dimension for software testing. In traditional waterfall software development software testing has approached the end point and begins with resource planning, a test plan is designed and test criteria are defined for acceptance testing. In this process most of test plan is well documented and it leads towards the time-consuming processes. For the modern software development methodology such as agile where long test processes and documentations are not followed strictly due to small iteration of software development and testing, lean canvas transformation models can be a solution. This paper provides a new dimension to find out the possibilities of adopting the lean transformation models and metrics in the software test plan to simplify the test process for further use of these test metrics on canvas.

Towards the Model-driven Software Configuration Management Process/ Modeļu vadāmais programmatūras konfigurācijas pārvaldības process/ Процесс управления конфигурациями программного обеспечения, основанный на моделях

Abstract

Software configuration management is one of the most important disciplines within the software development project, which helps control the software evolution process and allows including into the end product only tested and validated changes. To achieve this, software management completes certain tasks. Concrete tools are used for technical implementation of tasks, such as version control systems, servers of continuous integration, compilers, etc. There are situations when some tools or scripts are implemented to support small particular parts of complex software configuration management process without a general picture of total process. Maintenance of such solutions is complex and more expensive than it could be. The study describes a model-driven configuration management approach, which foresees the development of an abstract environment model for the configuration management process that later is transformed to lower abstraction level models and tools are indicated to support the technical process. This approach allows implementing all tools and solutions according to the planned configuration management process and developing reusable solutions.

Models and Methods of Software Configuration Management

Abstract

The paper provides collection of experience of developing models and methods for implementation of software configuration management process. Nowadays, during the age of agility, startup of new software development projects is like an explosion. Sometimes, in a few days a customer is willing to get the first release, but formalized and reusable process for its creating is not ready yet. Software configuration management controls the evolution of software items and supports building and deployment process for product releases. Models and methods for implementation of software configuration management are presented in the paper. Unlike other approaches, the provided models and methods are related to decrease software configuration management implementation time in new projects. The paper provides a simplified use case to illustrate practical application of the mentioned methods and models.
