NUSSELT NUMBERS FOR A POWER-LAW FLUID FLOW BETWEEN FIXED PARALLEL PLATES WITH CONSTANT HEAT FLUXES IN THE PRESENCE OF VISCOUS DISSIPATION [PDF]
M.U. UWAEZUOKE, S.O. IHEKUNAFully developed laminar heat transfer of non-Newtonian fluids between fixed parallel plates has been studied both thermally and hydrodynamically, accounting for the effect of the moving fluid's viscous dissipation. Both plates are kept at distinct constant heat fluxes as the thermal boundary condition. Analytical solutions to the energy equation and subsequent Nusselt number were found using the Brinkman number and power-law index. The results demonstrate that the power-law index of the moving fluid has an impact on heat transmission. Pseudo-plastic and dilatant fluids exhibit differing heat transfer characteristics when viscous dissipation is present. It is important to take into account the major impacts of viscous dissipation on heat transmission between parallel plates under specific circumstances.

Energy consumption in an SOA that combines Spark, MapReduce and HDFS [PDF]
Mint Mohamed Lemin Zeinebou, Noura AKNIN,Salihi Mohamed Lemin, Moustapha Mohamed LeminDuring any operation of management of large volumes of data, we must use many frameworks together which appears efficient but consumes more economic energies and material. In this article, we have made a comparison between two service-oriented architectures. Each one has, as purpose, to gather a set of advanced frameworks to manage the largest amount of data collected but with the least possible energy consumption. The first architecture is based on Spark and Hadoop HDFS. The second one is based on Hadoop MapReduce and Hadoop HDFS. All of them use the Dynamic voltage and frequency scaling technique to maximize the energy consumed. After the calculation of this consumption for the two architectures, we concluded with a third architecture that uses less consumption than the first two architectures.
Improvement energy-efficiency for industrial applications: Analysing the fluorescent and LED illumination [PDF]
Ranjana Ubale, Madhukar Zambare, Nitin KulkarniThis research paper presents a comparative study on the energy consumption and efficiency of fluorescent and LED lighting in an electronic workshop. The aim is to identify the most energy-efficient lighting solution for optimal energy consumption while ensuring adequate illumination for the workspace. The study involves a comprehensive analysis of both lighting technologies, including their energy consumption, lifespan, color rendering index (CRI), maintenance requirements, and overall cost-effectiveness. The results provide valuable insights into selecting the most suitable lighting option for electronic workshops, thereby promoting sustainable energy practices. Both scenarios have been modeled and simulated by using Dialux and photometric data for the luminaires have been gathered by using simulation software. The LED lighting system consumed approximately 68% less energy than the fluorescent lighting system, resulting in substantial energy savings over the long term.

AN ANALYTICAL APPROACH TO THE EFFECTS OF VISCOUS DISSIPATION ON FORCED CONVECTIVE HEAT TRANSFER FOR A COUETTE-POISEUILLE FLOW OF POWER-LAW FLUID BETWEEN ASYMMETRIC BOUNDARY CONDITIONS VISCOUS DISSIPATION [PDF]
M.U. UWAEZUOKE, S.O. IHEKUNAAn analytical approach to the effects of viscous dissipation on forced convective heat transfer for a Couette-Poiseuille flow of power-law fluid between asymmetric boundary conditions is considered. The studied Couette-Poiseuille flow is simply a maximum velocity flow and a numerical solution is required to find the region where the maximum velocity occurs. A new analytical formula for the Nusselt number was obtained regarding the heat flow ratio between upper and lower parallel plates and the Brinkman number established for a power law fluid. The results which condensed to a few specific examples are consistent with previous findings. If we compare the Nusselt number and the Brinkman number, we see an asymptotic Brinkman number. This has a sign shift for the set of power law indices under consideration.
Design of Two Interleaved Error Detection and Corrections using Hsiao Code and CRC [PDF]
Sagar Wani, Ganesh NemadeWith the continuous downscaling of CMOS technologies, the issues of soft errors and reliability are set to become increasingly challenging. In order to detect and correct these errors and enhance reliability of the circuits, this paper describes a design of two interleaved Double-Adjacent-Error-Corrections (DAECs) for Error Detection and Correction (EDAC), using the Hsiao Code and Cyclic Redundancy Code (CRC). Hsiao codes are modified version of Hamming codes which are widely used in modern systems. A cyclic redundancy check (CRC) is a non-secure hash function designed to detect accidental changes to digital data in computer networks. It is characterized by specification of a generator polynomial, which is used as the divisor in a polynomial long division over a finite field, taking the input data as the dividend. The remainder becomes the result. CRCs are particularly easy to implement in hardware and are therefore commonly used. We also propose two storage formats and algorithm designs that can manage and store the 48-bit codeword in 8-bit and 16-bit memory devices, a typical satellite scenario where board space is scarce. We use Verilog, C++, and ModelSim to create and test our designs.
Using Artificial Intelligence in Project Management [PDF]
Yasser El Saie, Sara SaeedThe development of project management is going in a fast pace in accordance with the development of artificial intelligence, and researchers are racing to study the optimal ways to use it in project management in a more effective and sustainable manner. This research aims to study the use of artificial intelligence in project management and its constraints. The researcher found that artificial intelligence can be used for management of every project stage. The researcher concluded that feeding artificial intelligence with promising predictions professionally through previous projects will contribute in data collection with higher intelligence and faster than the employee who relies on intuition and emotional intelligence, and thus enables it to make the right decision and exploit the self-learning of the machine and its ability to make decisions, monitor the behavior of the project, predict its future trends and challenges. At the project level, we find that the role of artificial intelligence is highlighted in repetitive, multi-functional, and complex projects. At the project stage level, artificial intelligence is used more widely in the project planning stage, especially planning to manage project costs, schedule, productivity, risks, and safety. This research serves as a starting point for inputs represented by more focused research to study how to analyze, improve and organize the use of artificial intelligence and its challenges in each step of the project for converting it into outputs through a tangible process that may be represented by talking robots or applications on a mobile phone or something else

Cosmic Microwave Background [PDF]
Kedar Matheikal ManojThe cosmic microwave background (CMB) has revolutionized astrophysics. My paper describes its importance to high school students. CMB was first recorded by the Cosmic Background Explorer (COBE), a spacecraft launched to obtain CMB data. The first time the CMB was analysed in temperature, it was all the same, but reducing the fraction to 1/100,000 in temperature fluctuations showed us the current CMB anisotropies we see today(â€œCMB Introduction,â€ n.d.). This also answered the question of how galaxies and nebulas were formed. With the discovery of CMB anisotropies and using quantum fluctuations, scientists came up with a theory of acoustic oscillations; by combining data from other satellites they created the power spectrum, which is a graphical representation of the relationship between multipole and temperature fluctuations. Using CMB monopole cooling, scientists were able to calculate Hubbleâ€™s Constant, which encompasses the rate at which the universe is expanding in Megaparsec (Mpc) (1 Mpc = 3.24 Ã— 1020 km). With this paper, I want the readers to be inspired to pursue and unveil more secrets of our universe.
