Energy consumption cost and environmental effect are dynamic challenge to cloud computing. Data centers are the backbone of cloud computing. They continue to be challenging problems to energy efficiency. We investigated previous research based on energy efficiency approach and obtained the conditions to facilitate green cloud computing. Reducing energy consumption and emissions of carbon dioxide (CO2) in data centers represent open challenges and driving the future research work for green data centers. It is found that there is an urgent need for integrated energy efficiency framework fordata centers which combines a green IT architecture with specific activities and procedures that lead to minimal impact on environment and less CO2 emissions. The required energy efficiency framework should also consider the social network applications as a vital related factor in elevating energy consumption, as well as high potential for energy efficiency.

Software systems are important, yet poorly understood entities. Users, and at times even developers, do not always understand what is occurring within the software in use. The Exploratory Visualization project attempts to address the technical issues involved in helping users understand running computations, especially long-lived distributed computations. The three facets of this problem that we investigate in our project are

Interoperability is the ability of making systems and organizations to work together (inter-operate). Integrated interoperability represents the enterprise collective interoperability capability which composed of System interoperability and business interoperability. Business interoperability is further composed of other sub-capabilities: Strategy capability, operational capability, managerial capability, which have indirect impact on the effectiveness of system interoperability. Interoperability is broadly seen as an essential component of SMEs competitiveness and sustainability. Our research primary focus is the ‘how’ of achieving a state of interoperability that engages technology, people organizational mission, value and culture in collaborations to exchange information, knowledge or services—so that all can advance mission or achieve business success and sustainability. The objective of this research is to develop an effective and integrated interoperability Model for sustainable and adoptable SMEs. The model is empirically validated in Danish SMEs to identify the correlation between the integrated interoperability capability and the adaptive capabilities through an integrated interoperability capability model analysis. The empirical data analysis reveals that there is strong positive correlation between the firms integrated interoperability capability and their adaptive capability including: agility, resilience, and innovation.

Innovation management has recently received much attention from research, industry and state support. However, much of the research has focused on large enterprises with much available financial wealth and required planning infrastructure, in order to be effective at managing innovation. This paper aims to understand the factors that affect the innovation management process within Turkish SMEs. A number of interviews are conducted with 25 SMEs using three different innovation auditing models to capture and validate best practice techniques. The goals of the analysis are (a) to understand the Turkish SMEs current capabilities and innovation management practices in each organization and (b) to identify a set of recommendations that may facilitate and enhance innovation management in all participated SMEs. Results showed that the majority of the SMEs have apparent lacking of innovation strategic plan, culture, formal process and assessment approach to measure impact of innovation proje...

One of the main objective of educators is to identifying inspiring and interactive approach to learning, and to encourage students to be more receptive and co-operative in the classroom. To help educators in achieving these goals we employed constructivist epistemology and constructivist cognitive psychology, together with the use of Mind Maps and Mobile Knowledge (M-K) Toolkit. The toolkit can serve as the foundation for a new kind of integration of Internet resources and all classroom, laboratory, field experiences, and when used with “expert skeletal” Mind Maps to scaffold learning. It is our thesis that good theory-based use of the appropriate technology can increase the benefits of using Mind Maps in education and lead to dramatically improved education. In this paper we first explored the Mind Maps Concept, then we presented and explained the advantages of M-K toolkit and how this can support mind mapping and integration of a whole array of learning experiences. In the last se...

This paper introduces a formal method to assess the risk and the duration of software projects automatically. The method has been designed according the characteristics of evolutionary software processes. We introduce a set of metrics to measure productivity, requirement volatility and complexity. We construct a formal method based on these three indicators to estimate the duration and risk of evolutionary software processes. The approach introduces benefits in two fields: a) automation of risk assessment and, b) early estimation method for evolutionary software processes.

The purpose of the present study is to explore the relationship between the components of entrepreneurship education on the one hand and the antecedents of students’ entrepreneurial intentions, on the other hand. A casual comparative survey was conducted to find out the impact of entrepreneurship education on entrepreneurship education participants (n=198) and on non-participants (n=202). The sample was selected from GIII level students of Technical and Vocational Education and Training (TVET). The t-test was applied to study the mean difference. The structural equation modeling was used to study the relationship between the entrepreneurship education components and the antecedents of entrepreneurial intentions. The embedded research design was used to support the results of the quantitative dataset by means of the qualitative interviews of the entrepreneurship education participants (n=15). The results showed that there was an impact of entrepreneurship education on the student’s i...

Planned reuse of software artifacts can improve productivity and quality in software development, however, a planned reuse effort requires substantial investments in the process and the software repository. In case of failure of a reuse effort, the initial expenses may not be recovered. The likelihood of success may vary with the reuse strategy employed; hence, potential reuse adopters must be able to understand reuse strategy alternatives and their implications. This research identifies the characteristics of systematic software reuse strategies and evaluates how they contribute to a successful reuse program using survey data collected from seventy-one software development groups. Our results show that these characteristics cluster into five distinct reuse strategies and that each strategy has a different potential for success. Index Terms reusability, systematic software reuse, software process improvement, quality, reuse success, reuse classification scheme This manuscript is cur...

Over the last decade many SME organizations have understood the strategic importance of managing and leveraging a wide variety of intellectual assets that are usually found scattered across individuals, departments, documents, and databases. While various researchers and vendors have developed and implemented specialist Knowledge Management Frameworks (KMF) for large organization, many small and medium enterprise (SME) organizations still face the challenge of selecting affordable frameworks including strategies, tools, and methods, which fit their objectives and needs as SMEs and then successfully implementing such frameworks. This paper presents an empirically validated I-KMF to establish a solid foundation for evolving KM into sustained SME organizational best practices over time. The newly created knowledge contributes to the necessary diversity for organizational growth and renewal, while the application of knowledge leads to performance improvement or value creation. In the fi...

Managing innovation as a process is vital for entrepreneurs and businesses. Through our literature review we realized that the innovation measurement in many organizations does not appear to take place routinely within management practice and that, where it does, it tends to focus on output measures. Further, from the relatively small number of empirical studies of measurement in practice, measurement of innovation management appears to be under-taken infrequently as an ad hoc approach, and relies on outdated innovation frameworks due to the accelerated progress of technology and R&D management. The consequence of this is the absence of an updated rigorous and generic framework covering the range of all activities required to generate and manage ideas and turn these ideas into useful added values and new marketable products, services, or business model. In this paper we introducing generic but comprehensive framework that addresses the innovation management at both levels of the fir...

This paper addresses the problem of how to produce reliable software that is also flexible and cost effective for the DoD distributed software domain. DoD software systems fall into two categories: information systems and war fighter systems. Both types of systems can be distributed, heterogeneous and network-based, consisting of a set of components running on different platforms and working together via multiple communication links and protocols. We propose to tackle the problem using prototyping and a "wrapper and glue" technology for interoperability and integration. This paper describes a distributed development environment, CAPS (Computer-Aided Prototyping System), to support rapid prototyping and automatic generation of wrapper and glue software based on designer specifications. The CAPS system uses a fifth-generation prototyping language to model the communication structure, timing constraints, I/O control, and data buffering that comprise the requirements for an em...

ABSTRACT Software development today is a complex area, in which new problems and challenges constantly arise, competition is rather high, and it is difficult to maintain high position on the market. This paper aims to introduce and develop a validated prototype-based RAD model using the evolutionary approach with the purpose of minimizing the risk of changes in software engineering and to have a product that meets its expectations in terms of functionality, cost, quality, and delivery schedule. Rapid application development (RAD) is created to present a higher level of responsibility that includes both a business unit requirement capturing and testing. Contact and interview case study participants approach are taken in deriving and validating the proposed model. Then, survey instruments undergo for testing and evaluation process for measuring the effectiveness and efficiency of the proposed model. The case study results showed reduction in the project risk to be behind of the delivery schedule, cost of software development, improve the quality of the system and deliver software that actually meets the needs of users.

Innovation is crucial to give a competitive edge for Small and Medium Enterprises in Turkey, especially in this period that is characterized by a significant increase in competition between Small and Medium Enterprises and spectacular global marked change. As realized through the literature review, measuring innovation in many organizations are not routinely taking place as one of the most important administrative practices, and that, where it does, it tends to focus only on measuring the volume of production. Moreover, through a number of empirical studies in Small and Medium Enterprises practices, the innovation management are based on obsolete innovation management frameworks because of rapid advances in technology and management. As a result of this there is no specific framework which fits the Small and Medium Enterprises needs and capacity to cover all required activities to produce and manage ideas and turn those ideas into added values and new marketable products, services or new business models. In this paper we offer a generic but comprehensive and integrated innovation management framework for both levels companies level and projects level. By applying this framework in a particular context, Small and Medium Enterprises managers will be able to assess the activity of the department of innovation, and identify gaps, weaknesses and the potential of improving innovation performance.

SMEs need to innovate in services in order to survive and to create value. Service SMEs are facing the challenge of offering their customers continuously improved or completely new services and hence require service innovations to achieve and sustain competitive advantage. We used service value creation capability to assess service innovation capability of SMEs. Service value creation capability is a holistic approach which consists of Strategic capability, Managerial capability, Organizational capability and Adaptive capability to transform an SME into a value creation SME. It offers an overview of service value creation capability and activities against which service SMEs can critically reflect their service innovation performance. Our research primary focus is to explore and to find the relationship of service value creation capability with service innovation capability and to assess the service innovation by using a proposed model for service value creation capability. The model is empirically validated in Danish and Turkish SMEs to identify the correlation between the service value creation and service innovation through an integrated service value creation capability model analysis. The empirical data analysis reveals that there is strong positive correlation between the SME’s service innovation capability and service value creation capability (strategic capability, managerial capability, operational capability and adaptive capability).
