The paper reveals multidimensional nature of organizational culture. When investigating its influence on success only performance influencing dimensions must be under consideration. The authors suggest the ways for reducing their number: content analysis and hierarchical structuring method. The system (list) of dimensions was formed by using the mentioned methods. Questionnaire was made. Relationship between dimensions and their influence on performance was tested. Firstd Published Online: 14 Oct 2010

Understanding developer productivity is important to deliver software on time and at reasonable cost. Yet, there are numerous definitions of productivity and, as previous research found, productivity means different things to different developers. In this paper, we analyze the variation in productivity perceptions based on an online survey with 413 professional software developers at Microsoft. Through a cluster analysis, we identify and describe six groups of developers with similar perceptions of productivity: social, lone, focused, balanced, leading, and goal-oriented developers. We argue why personalized recommendations for improving software developers’ work is important and discuss design implications of these clusters for tools to support developers’ productivity.

Human-computer interaction is constantly evolving in many areas and facets of modern society. Analyzing these interactions can provide a more balanced understanding of these technological advances as they pertain to people’s lives. Experience-Based Human-Computer Interactions: Emerging Research and Opportunities is a pivotal reference source that provides in-depth discussions on the progression and contemporary applications of human-computer interaction. Highlighting relevant topic areas such as semantic support, software intensive systems, ontology applications, and conceptual objects, this publication is ideal for engineers, academicians, students, and researchers that would like to attain more information on recent advances being made to bridge the gap between human and computer interactions.

The article is concerned with the method for structuring the electronic archive of technical documentation on the basis of the domain-specific ontology. The ontology formal model, the technical document model, and the algorithm for clustering electronic archive content that has its origins in the modified fcm-method are presented. The authors are pioneered in offering the formalization of the measure of distance between ontological representations of the archive technical documents on the basis of hierarchy transformation complexities comparison. Different types of semantic relations between ontology concepts should be taken into account. Thus, the article considers the experimental results of the subset of the electronic archive technical documentation of the large project organization.

In this paper we propose two approaches to solving problems of time series prediction, first, on the basis of fuzzy time series models, models of fuzzy tendencies and the second based on the F-model transformations and patterns of genetic algorithms. The comparative experiment to evaluate the accuracy of both methods of forecasting.

With rapid growth in the world population, tremendous pressure towards cities has triggered different smart city initiatives from government as well as private sectors to contribute in finding sustainable solutions for these overwhelming issues. Internet of Things has also attracted unprecedented attention in the last few years. It connects billions of sensor devices to the Internet which can be used in managing smart cities efficiently and effectively. In this paper, we observe the concepts of sensor enabled Internet of Things and describe its potential in building of a smart city. Our goal is to revise the latest trends of existing findings in this research area and identify some major issues concerning the sensor enabled Internet of Things for smart cities.

Also called energy scavenging, energy harvesting captures, stores, and uses “clean” energy sources by employing interfaces, storage devices, and other units. Unlike conventional electric power generation systems, renewable energy harvesting does not use fossil fuels and the generation units can be decentralized, thereby significantly reducing transmission and distribution losses. But advanced technical methods must be developed to increase the efficiency of devices in harvesting energy from environmentally friendly, “green” resources and converting them into electrical energy. Recognizing this need, Energy Harvesting: Solar, Wind, and Ocean Energy Conversion Systems describes various energy harvesting technologies, different topologies, and many types of power electronic interfaces for stand-alone utilization or grid connection of energy harvesting applications. Along with providing all the necessary concepts and theoretical background, the authors develop simulation models throughout the text to build a practical understanding of system analysis and modeling. With a focus on solar energy, the first chapter discusses the I-V characteristics of photovoltaic (PV) systems, PV models and equivalent circuits, sun tracking systems, maximum power point tracking systems, shading effects, and power electronic interfaces for grid-connected and stand-alone PV systems. It also presents sizing criteria for applications and modern solar energy applications, including residential, vehicular, naval, and space applications. The next chapter reviews different types of wind turbines and electrical machines as well as various power electronic interfaces. After explaining the energy generation technologies, optimal operation principles, and possible utilization techniques of ocean tidal energy harvesting, the book explores near- and offshore approaches for harvesting the kinetic and potential energy of ocean waves. It also describes the required absorber, turbine, and generator types, along with the power electronic interfaces for grid connection and commercialized ocean wave energy conversion applications. The final chapter deals with closed, open, and hybrid-cycle ocean thermal energy conversion systems.

Organizational culture is one of the determinants of a company’s competitiveness, and consequently, realistic analysis of the link between these two elements can provide relevant information to optimize it and, on this basis, to increase the company performance. The direct implications of organizational culture are important in business efficiency. Increasing the quality of human resources, efficient exploitation of material resources, and financial mean the achievement of provisioned levels of turnover, market share, or value added. Organizational culture, through its forms and manifestations (symbols, rules of behavior, customs, ceremonies, history, prestige, and authority of managers and employees), influences and leads to a series of behaviors and attitudes so that employees can tap the full potential for achieving goals. Eliminating fear in an organization is an essential requirement, as it encourages people to take more risks, responsibilities, and initiatives. Remarkable results can be achieved if performance will be measured properly and if a direct reward is chosen.
