Numerical study of circle fractal grid perforated plate as a turbulent generator in combustion chamber

Fractal grids can be used to design turbulent flows with low power losses and high turbulence intensities for intense yet economic mixing over a region of designed length and location. The introducing circle grid perforated plate is the main aim of this present paper. In this numerical work, we want to ascertain a new approach in turbulence generators on the structure of premixes flames using perforated plate fractal-grids pattern. In this paper, we compared circle grid perforated plate by varies using its diameters, spacing and number of holes on the plate. The result showed good perceptivity of the fractal generated turbulence and the fractal flow physics. The turbulent intensity can be increased by a grid with higher blockage ratio

IT, E-Commerce, Individual and Team Learning Environment

This paper is about impact of Information Technology on creating learning environment and on e-commerce. Because of innovations on the field of IT, individuals and businesses are affected; however with those changes also need for capacity building and long life learning is appearing. In addition, companies and markets can not be considered as a static concept, but they are changing and evolving every day. Those changes are also brining innovations in management procedures and in production of goods and services. Implementation of e-commerce is trigering also the implementation of other e-tools that can help companies to manage in better way their resources, customers and finance

Peripherality and proximity. Do business support services matter?

This essay is based on empirical evidence from the case of Tuscany (Italy) and follows previous work on the role and meaning of image in regional development and innovation policies (Bellini, 2004). Discussions about image and branding policies is usually placed in the framework of "place marketing" and marketing literature helps in defining the features, components and main characters of image and of its relationship with local identity. We suggest, however, that managing images is also a political process with significant impact in supporting and shaping the scenario (perceptions and expectations) for innovation policies. In fact this process implies a competition between images in order to "control" the representation of the past, present and future of an area. This competition aims at influencing the policy agenda by manipulating the gap between image and identity. In other words, we suggest that image-related policies should be considered part of the toolbox of a modern innovation policy.

The Effects of Information And Communication Technology In Hungarian Economic Sectors

As the author could not find a reassuring mathematical and statistical method in the literature for studying the effect of information communication technology on enterprises, the author suggested a new research and analysis method that he also used to study the Hungarian economic sectors. After a brief introduction to the theoretical background of the Information Age, the author examines the question of what factors have an effect on their net income is essential for enterprises. First, the potential indicators related to economic sectors were studied, then the author compared those indicators to the net income of the surveyed enterprises. The data resulting from the comparison showed that the growing penetration of electronic marketplaces contributed to the change of the net income of enterprises in various economic sectors. Among all the potential indicators, only the indicator of electronic marketplaces has a direct influence on the net income of enterprises. It was practical to determine two clusters based on the potential indicators

A Fellowship Approach to Accelerating Social Entrepreneurs

When Echoing Green, a nonprofit focused on unleashing next-generation talent, was founded in 1987, the term "social entrepreneur" was not widely used. Emerging leaders who wanted to change the world had limited options to access capital and programmatic support aside from its Fellowship program. Forty million dollars in seed-stage funding and strategic assistance to nearly 700 entrepreneurs later, Echoing Green has witnessed social entrepreneurship become a global movement.In recent years, Echoing Green has recognized two field-level trends within its Fellow community. First, for-profit business models to effect social and environmental change and impact investing (investments made to generate social and environmental impact alongside a financial return) have increased in popularity. At the same time, the business accelerator landscape has grown, and many entrepreneurs are participating in multiple programs. Globally, a plethora of accelerator programs are now employing a variety of services and funding models to launch start-ups.Echoing Green also began accepting more entrepreneurs using for-profit business models into its Fellowship and deepening its engagement with its Fellow alumni community. In 2014, it piloted an impact investing "inflection cohort" of Fellow alumni running for-profit and hybrid social enterprises. Its goal was to fill gaps in support and funding through the Fellows' common critical inflection moment: transitioning from early-stage funding to raising more sophisticated institutional growth capital.In this white paper, Echoing Green describes this impact investing inflection cohort pilot and shares the social entrepreneurs' data to shed light on how and if the inflection cohort model succeeded in enabling the early-stage social entrepreneurs to grow, attract investment, and deliver impact
