The purpose of research is to implement learning system website through knowledge sharing to improve the competence of early childhood teachers, especially pedagogical and professional competence. To improve the quality of early childhood education in community-based models, the ability of early childhood education teachers is urgent to develop. Government and related institutions are required to participate in improving the competence of early childhood education teachers that scattered throughout the country, especially for those who have not completed formal education to become early childhood teachers. Improving the quality of early childhood teachers through conventional training activities organized by the central and local governments are very limited. System development methodology that is used in this research is the rapid application development, which consists of three phases: planning, workshops design, and implementation. The result of this research is the early childhood education teachers can utilize learning systems website, as knowledge sharing media. The system can be a model of the use of a knowledge management system as the medium of learning for Early Childhood Education teacher to improve their pedagogical and professional competences.

Advances in database technologies are moving the attention of data managers from well known structured relational databases (SQL-Like DBs) towards NoSQL approaches, especially to address big data issues. However, changing technologies in consolidated data management system is hard and requires great investments. Deploying hybrid SQL-NoSQL approaches could be a good solution to speed up the transition in many domains and information systems, but a formal data model to design hybrid databases is necessary. This paper presents a new data model aimed at solving this issue. Starting from the well known E-R model, we introduce some additional components to identify data and “big data” in the system, in order to drive the implementation of SQL-like solutions to manage data, and NoSQL solutions to manage big data. The paper also discusses a Hospital Information System use case, to clearly show how the proposed enriched E-R model can be successfully adopted.

The current popular method in analysis and design phase is object-oriented analysis design (OOAD). The OOAD method aims to identify the objects which are responsible for their own. Mostly, the measurements of OOAD results are using verification and validation technique. A more demanding approach is expected from the OOAD method to improve software development process. To address this issue, this paper use Capability Maturity Model Integration (CMMI) as integrated software process improvement standard and approach. The purpose of CMMI is to improve process in creating product or services within organization. Therefore, the idea of improving process using CMMI will be applied for optimizing OOAD. The proposed method in this study is by constructing checklist criteria which already comply with requirement development process area in CMMI. Each criterion will be given certain score, then the score will summarize into total number from the assessment towards the Unified Modeling Languange (UML) Diagrams. The result obtained score of 185 for all criteria in the checklist and achieved 77,08% of CMMI level implementation, which categorized into Large implementation (LI). The score also means that the UML diagrams are quite good and could be delivered through the next steps of software development life cycle. (C) 2015 The Authors. Published by Elsevier B. V.

Data-related modeling capabilities within Business Process Model and Notation (BPMN) are intentionally restricted to being handled within dynamic process perspective and do not enable implementation of individual processes in dedicated workflow engines and/or iterative improvement of process specifications by running simulations using specialized software. Thus, achieving the level of executable processes effectively is largely dependent on the proper selection and introducing notations that are complementary to BPMN. The current paper is aimed at identification of suitable complementary techniques to support the organizations' business process models with document and data structure-oriented specifications as well as verification of the support for such techniques among future business analysts. Authors develop and exemplify original UML profile for BPMN data object modeling that serves as a basis for acceptance research. Models prepared with the profile are assessed using a questionnaire survey designed in accordance with Unified Theory of Acceptance and use of Technology (UTAUT).

We address the problem how high-fidelity verification results about the hybrid systems dynamics of cyber-physical flow systems can be provided at the scale of large (traffic) networks without prohibitive analytic cost. We propose the use of contracts for traffic flow components concisely capturing the conditions for a safe operation in the context of a traffic network. This reduces the analysis of flows in the full traffic network to simple arithmetic checks of the local compatibility of the traffic component contracts, while retaining higher-fidelity correctness guarantees of the global hybrid systems models that inherits from correct contracts of the hybrid system components. We evaluate our approach in a case study of a modular traffic network and a prototypical implementation in a model-based analysis and design tool for traffic flow networks.

E-learning system involves an open participation of student, teacher, and administrator among different regions in the world. Due to the use of Internet as electronic communication media, there are several types of risks and threats such as alternation or deletion of student's marks given by a teacher may hamper the E-learning environment in different ways. To implement privacy and confidentiality of the information, we must use suitable encryption technique. In this paper, we have proposed an object-oriented modeling of international data encryption algorithm (IDEA) for implementation of privacy and confidentiality of information which would be communicated between teacher and student at the time of viewing marks for a subject. For an efficient design, we use UML-based approach. © 2015, Springer India.

In this paper, we present a meta-model approach for the design and implementation of Data Warehouses (DWs). The approach is made up of a set of transformation rules as a mechanism to extract multidimensional schemas from the logical description of the operational Database and a Computation Independent Model (CIM) for user requirements definition. As a result we have implemented an Eclipse based prototype that generates from the logical description of the operational Database and user requirements the multidimensional schema that best reflects users requirements. Next, for multidimensional schemas generation, we use user requirements to guide the selection that is supported by the operational Database that is most likely to satisfy users requirements. Finally, we define a tool for the data Warehouse implementation.

A graph mining approach for detecting identical design structures in object-oriented design models

The object-oriented approach has been the most popular software design methodology for the past twenty-five years. Several design patterns and principles are defined to improve the design quality of object-oriented software systems. In addition, designers can use unique design motifs that are designed for the specific application domains. Another commonly used technique is cloning and modifying some parts of the software while creating new modules. Therefore, object-oriented programs can include many identical design Structures. This work proposes a sub-graph mining-based approach for detecting identical design structures in object-oriented systems. By identifying and analyzing these structures, we can obtain useful information about the design, such as commonly-used design patterns, most frequent design defects, domain-specific patterns, and reused design clones, which could help developers to improve their knowledge about the software architecture. Furthermore, problematic parts of frequent identical design structures are appropriate refactoring opportunities because they affect multiple areas of the architecture. Experiments with several open-source and industrial projects show that we can successfully find many identical design structures within a project (intra-project) and between different projects (inter-project). We observe that usually most of the detected identical structures are an implementation of common design patterns;however, we also detect various anti-patterns, domain-specific patterns, reused design parts and design-level clones.

In this paper, we propose model driven software development and Security Performance Framework Model to maintain the balance between security and performance for web applications. We know the large scale enterprise web applications are naturally complex and rigid to maintain. To deal with this complexity of web applications, we propose OMG's UML modeling language for forward engineering and SPF based software engineering practices to improve the performance of web applications. Model driven development approaches focus on software automation with generators that translate models into code. One of the major difficulties in developing web applications with object-oriented modeling is to translate a designed model into code that satisfies required real-time performance. We propose a method of automatic code synthesis ensuring that the synthesized code to be efficient enough to use the minimal amount of resources such as CPU time and memory. For implementation of Security Performance framework based trusted operating system, we propose object oriented based Code translation through forward engineering for the same web application. The goal of this paper is to demonstrate a process in which such translation can be formally verified. In this paper, we propose SPF based code verification and object oriented design process for web applications.

A Novel object-oriented Software Cache for Scratchpad-Based Multi-Core Clusters

JOURNAL OF SIGNAL PROCESSING systems FOR SIGNAL IMAGE AND VIDEO TECHNOLOGY 2014年第1-2期77卷 77-93页

作者： Pinto, Christian Benini, Luca Univ Bologna DEI Bologna Italy

A widely adopted design paradigm for many-core accelerators features processing elements grouped in clusters. Due to area, power and design simplicity, processors in the same clusters are often not equipped with data-caches but rather share a tightly coupled data memory (TCDM). Even if the use of a TCDM is more energy and area efficient than a cache, it requires a higher programming effort because memory transfers need to be explicitly managed (often with DMA-based off-chip memory to TCDM copies) . In this context software caches can be used to automatically transfer data between the local TCDM and the external memory, simplifying the task of the programmer. Despite their ease of use, software caches may incur in non-negligible overheads due to repeatedly invoking the cache runtime. Many-Core systems, however, are often used today for applications in which the unit of computation is not the single memory word but rather more complex data objects, opening room for optimization in software cache runtimes. A good example are computer vision applications, where the computation involves multi-byte objects (e.g feature descriptors). In this paper we present a software cache implementation for the STMicroelectronics STHORM acceleration fabric, with special focus on object-oriented caching techniques aimed at reducing as much as possible the global overhead introduced by the proposed software cache. Our software cache is validated by a set of experiments, and three case studies of object-oriented software cache for computer vision applications.
