TOP Most Read Articles in Informatics Engineeringieijjournal
Informatics is rapidly developing field. The study of informatics involves human-computer interaction and how an interface can be built to maximize user-efficiency. Due to the growth in IT, individuals and organizations increasingly process information digitally. This has led to the study of informatics to solve privacy, security, healthcare, education, poverty, and challenges in our environment. The Informatics Engineering, an International Journal (IEIJ) is a open access peer-reviewed
journal that publishes articles which contribute new results in all areas of Informatics. The goal of this journal is to bring together researchers and practitioners
from academia and industry to focus on the human use of computing fields such as communication, mathematics, multimedia, and human-computer interaction design and establishing new collaborations in these areas.
We daily lose our energy while travelling like on road, stairs but what-if we can store that energy and use when required.
We worked on a device that can convert human effort into electrical energy and store this energy for further use.
We tried to fabricate the device which utilize the human effort to generate the electricity and promote the non-conventional energy source.
CFD AND DOE STUDY THE EFFECT OF SOLAR CHIMNEY TOWER RADIUS, HEIGHT, CHIMNEY R...IAEME Publication
Solar chimney technology is a very promising solar thermal electricity generating technology. In this project CFD technology is used to investigate the changes in flow kinetic energy caused by the variation of tower flow area with height. It was found that the tower area change affects the efficiency and mass flow rate through the plant.
Smooth Particle Hydrodynamics for Bird-Strike Analysis Using LS-DYNAdrboon
In this second of a three-paper sequence, we developed a standard work using the Smoothed Particle Hydrodynamic (SPH) approach in LS-DYNA and compared the results against those the Lagrangian model and available experimental results. First, the SPH model was validated against a one-dimensional beam centered impact’s analytical solution and the results are within 3% error. Bird-strike events were divided into three separate problems: frontal impact on rigid flat plate, 0 and 30 deg impact on deformable tapered plate. The bird model was modeled as a cylindrical fluid. We successfully identified the most influencing parameters when using SPH in LS-DYNA. The case for 0 deg tapered plate impact shows little bird-plate interaction because the bird is sliced in two parts and the results are within 5% difference from the test data available in the literature, which is an improvement over the Lagrangian model. Conclusion: The developed SPH approach is suitable for bird-strike events within 10% error.
Piezoelectric Energy Harvesting under Air Flow Excitation.Franco Bontempi
This study focuses on the numerical analysis of a high efficiency Energy Harvesting device, based on piezoelectric materials, for the sustainability of smart buildings, structures and infrastructures. Before that, a
comprehensive literature review on the topic takes place. The device consists in an aerodynamic fin attached to a piezoelectric element that makes use of the air flow to harvest energy. The principal utilization of this device is for energy autonomous sensors, with applications in bridges, transportation networks and smart buildings. The results are corroborated by advanced analytical and numerical analyses (in ANSYS®) that demonstrate the energy harvesting capacity.
A REVIEW ON LIFTING AND ASSEMBLY OF ROTARY KILN TYRE WITH SHELL BY FLEXIBLE G...Journal For Research
Heavy kiln tyre Lifting, rigging and assembly with kiln shell is done manually by use of heavy crane and labour. This traditional technique is not safe. The challenge is find out solution for ease the process and cost effective because of limitations of the rigging system, erection area, can be managed safely by the kiln tyre suspender equipped by jaws and suspender beam. This review paper deals with the study and analysis of different papers which are deals with different lifting, gripping and installation techniques and other aspects analysis with software, experimentation and optimization etc.
