Computing resource and work allocations using social profiles
(Wydawnictwa AGH, 2013) Lavin, Peter; Kenny, Eamonn; Coghlan, Brian A.
If several distributed and disparate computer resources exist, many of which have been created for different and diverse reasons, and several large scale computing challenges also exist with similar diversity in their backgrounds, then one problem which arises in trying to assemble enough of these resources to address such challenges is the need to align and accommodate the different motivations and objectives which may lie behind the existence of both the resources and the challenges. Software agents are offered as a mainstream technology for modelling the types of collaborations and relationships needed to do this. As an initial step towards forming such relationships, agents need a mechanism to consider social and economic backgrounds. This paper explores addressing social and economic differences using a combination of textual descriptions known as social profiles and search engine technology, both of which are integrated into an agent technology.

Ekologiczne i ekonomiczne uwarunkowania wykorzystania zasobów przy produkcji kruszyw łamanych
(Wydawnictwa AGH, 2005) Czopek, Kazimierz
There are in production process of broken aggregates the contrary ecological and economic purposes. From ecological point of view it should be tried to do the maximization in using up resources. So far the production of aggregates needs to use several stages of feed crushing. As the effect there is created more and more small fractions treated as waste. From economic point of view the best situation would be to sell the highest price (the most expensive) fraction: chippings, voussoir, breakstone. The mediate solution can be to offer the lowest granulation fractions. This paper describes the optimum way of choice in this matter, concerning the kind of mineral necessary for recast process, demand of aggregates, prices of particular fraction of aggregates.

Photovoltaics' environmental and economic analysis
(Data obrony: 2010-07-22) Ciesielska, Joanna
Wydział Geologii, Geofizyki i Ochrony Środowiska
In the present analysis the author has tried to gather and evaluate accessible data concerning complete cradle-to-grave processes for PV technologies, such as crystalline silicon (mainly multi-crystalline silicon), amorphous silicon, cadmium-telluride and copper-indium-selenide thin film. The analyzed data is in the area of energy analysis, energy payback time, material flow analysis (resource depletion, emissions to the environment, module decommissioning and recycling) as well as health and safety risks. The basis of the research and information gathered are publications and conference papers as well as data published on the Internet. The thiesis diagnoses the extent to which mentioned technologies are a sustainable source of energy. Because of the instability of the market and very fast changes connected with the development of the mentioned technologies as well as scarce data in some areas, the overall conclusions should be considered as general and indicative rather than undeniably showing the current state of the PV industry.

The business model for access to affordable RE on economic, social, and environmental value - a review
(Wydawnictwa AGH, 2023) Erdiwansyah, Erdiwansyah; Gani, Asri; Mamat, Rizalman; Nizar, Muhammad; Yana, Syaifuddin; Rosdi, S. M.; Zaki, Muhammad; Sardjono, Ratnaningsih Eko
Renewable energy has the potential to power the global economy and effective business models will significantly aid this goal, being among the most critical factors in spurring expansion in the energy industry. This paper reviews articles that discuss business models in the renewable energy sector. Longterm economic, social, and ecological stability is concerned. Previous studies have neglected the environmental sustainability of renewable energy business models, focusing on their technical, social, and economic aspects, primarily for energy access. The business models for solar home and pico systems relied heavily on lowering costs through creative payment plans for customers to be commercially viable. The demand for mini-grids requires end users to launch businesses that can leverage electrification initiatives to be commercially viable. The success of a mini-grid depends on the average consumption and revenue per user. Affordability, unmet energy needs, low electricity demand, lack of financing, unfamiliar business models, and immature markets have impeded energy access in Indonesia. Our analysis revealed that future studies in this field must include environmental sustainability to provide a complete picture for decision-makers. Renewable energy needs in Indonesia can be achieved through the sustainability domain, policy makers can consult this evidence set.
