Comparative Study of Optimization of HRES using HOMER and iHOGA Software

2018-12-07T08:02:17Z

Title: Comparative Study of Optimization of HRES using HOMER and iHOGA Software Authors: Saiprasad, N; Kalam, A; Zayegh, A Abstract: There has been several methodologies to size hybrid renewable energy system (HRES). This paper provides the comparative study of the simulation results between HOMER and iHOGA software packages. These two softwarepackages are used to optimally size renewable energy systems for a micro-grid. A small community in Aralvaimozhi, India is considered. Aralvaimozhi has a good potential of Solar energy and Wind energy resources. If these resources are trapped efficiently using HRES, an efficient micro-grid could eventually replace the present old and less efficient electricity grid. In this study, the optimally sized HRES with least value of Net Present Cost (NPC) resulted from HOMER and iHOGA software packages have been discussed and their results have been compared for a definite scenario.

Title: Innovation Management and Cooperation in the Government of Social Economy Entities Authors: Medraño, Maria del Carmen Muñoz; Peñalver, Antonio Juan Briones; Santos, José António C Abstract: The Social Economy (SE) is characterized by a strong social orientation designed to meet the needs of various stakeholders, especially employers and customers. The government entity and influences innovativeness and willingness to establish cooperation agreements with a primary outcome of the entity via reflection governance policies. This paper aims at demonstrating that social enterprises have a social culture based on values and principles, which reflect corporate governance strategies based on innovation and cooperation. To this end, relationships are proposed where market decisions and cooperation with internal and external agents can be considered the key factors for success in this type of business partnerships.

Title: Tool-Wear Estimation in Cnc Machine Based On Fusion Vibration-Current and Neural Network Authors: Trejo-Hernandez, M; Osornio-Rios, R A Abstract: The costs of the cutting tools and their replacement become an important amount of the total production costs in a manufacturing process. This work presents a methodology based on machine vibration, servomotor electric current and an artificial neural network to obtain the tool-wear detection in CNC machine inserts. The effectiveness of this proposal was tested in the tool of CNC lathe machine and validated with the image quantification. Page(s): 688-691

A New Receiver for a Passband System with CFSK Modulation: The STTS-CFSK Receiver

2018-12-07T07:42:00Z

Title: A New Receiver for a Passband System with CFSK Modulation: The STTS-CFSK Receiver Authors: Chakka, R; Ahuja, A Abstract: A new receiver, named STTS-CFSK receiver, for passband with CFSK modulation, is developed. This new receiver uses correlations in the transmitted digital signals wisely, while assuming the correlation parameters p and q known at the receiver. The conventional receiver, the STS-CFSK receiver, does not take these correlations into consideration. Both the receivers are evaluated and compared, by extensive simulation based experimentation. Performance of the STTS-CFSK receiver is found to be superior to that of the STS-CFSK receiver, for SNR > 0 dB. Usefulness of this work for ‘Greening of Communication Technology’ is explained Page(s): 692-699
