Research ArticleOpen accessIn the abstractLOW-COST STRATEGIES TO SAVE ENERGY IN K-12 SCHOOLSNabil Nassif, Raymond C. Tesiero III, Harmohindar Singh, K. M. FlurchickAdvanced Energy Management Control Systems (EMCS) offer an excellent means of reducing energy consumption in Heating, Ventilating and Air Conditioning (HVAC) systems while maintaining and improving indoor environmental conditions. This can be achieved through the use of computational intelligence and optimization with a building automation system and multiple sensors, which can be quite expensive. However, energy awareness and proper scheduling … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 17 Mar 2014 · 8,157 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvolution of Neural Controllers for Robot Navigation in Human EnvironmentsGenci Capi, Hideki TodaProblem statement: In this study, we presented a novel vision-based learning approach for autonomous robot navigation. Approach: In our method, we converted the captured image in a binary one, which after the partition is used as the input of the neural controller. Results: The neural control system, which maps the visual information to motor commands, is evolved online using real … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 6,784 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign of Sustainable Relief Housing in Ethiopia: An Implementation of Cradle to Cradle Design in Earthbag ConstructionBrooke Barnes, Huantian Cao, Theodore Drab, Jason PearsonProblem statement: Urbanization in Ethiopia resulted in urban poverty and homelessness. In this study, a sustainable relief housing prototype that aided in sheltering homeless citizens was designed. To avoid repeating errors in urban development such as unsustainable resource consumption, it was necessary to look beyond traditional construction materials and methods. Approach: This design applied cradle to cradle design model to … …American Journal of Environmental Sciences, Vol. 5, Issue 2 · 30 Apr 2009 · 7,288 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAnalysis of Indoor CO2 Concentration Using Split Ventilation Systems as an Indicator of COVID-19 TransmissionManuel Batista, Oscar Bulgim, Ericka Matus et al.We measured the indoor CO2 concentration in occupied areas with ventilation systems that recirculate air without an external air supply. The average time required to achieve the highest probability of contagion was also measured based on the number of participants in the group. Three different experimental groups were evaluated: Group One (G1), which included 5 participants; Group Two (G2), with … …American Journal of Applied Sciences, Vol. 20, Issue 1 · 23 Aug 2023 · 6,051 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Passive Opportunity for Improving Air Quality in the Schools Environment: A Real-World Scale TestingPierpaoli Mattia, Fava GabrieleCan passive technology effectively enhance the indoor air quality? To improve classroom indoor air quality, an increase in ventilation and/or air purifiers are often suggested. In this study, a short-term intervention was implemented and investigated to evaluate the effects of a passive adsorbent surface on the pollutant deposition velocity and to improve the overall classroom air quality. We found that … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 3 Jun 2016 · 7,591 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffects of Novel Disk-type Furrow Opener Used in No-Tillage System on Micro Environment of SeedE. Seidi, S.H. Abdollahpour, A. Javadi, M. MoghaddamProblem Statement: Offset Double-Disk Opener (DDO) is a popular furrow opener in conservation tillage. It has some limitations such as negative suction to penetrate in the soil, hair pinning and mixing seed and fertilizer in the slot. Because of importance of separation of seed and fertilizer in the slot, by adding two horizontal mini disks to DDO a modified opener … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 9,155 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordVision Based Reconstruction Multi-Clouds of Scale Invariant Feature Transform Features for Indoor NavigationAbbas M. Ali, Md Jan NordinProblem statement: Navigation for visually impaired people needs to exploit more approaches for solving problems it has, especially in image based methods navigation. Approach: This study introduces a new approach of an electronic cane for navigation through the environment. By forming multi clouds of SIFT features for the scene objects in the environment using some considerations. Results: The system gives … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,220 accessesView PDF Cite
