Performance Analysis of Gas Turbine Power Plant; Effect of Operating Parameters
Journal ArticleThis study aims to evaluate the performance of a simple cycle gas turbine power plant by analysing the effect of different operating parameters. These operating parameters include compressor pressure ratio and compressor & turbine isentropic efficiencies. The study quantitatively assesses the exergetic efficiency and the exergy destruction of each unit in the cycle, as well as the power used or produced by the cycle. Any change in these parameters can significantly impact the power plant's overall performance through a specific unit in the cycle. For instance, increasing the compressor pressure ratio can reduce the temperature difference across the combustor, lessening the exergy destruction and improving the cycle’s overall performance. However, any decline in the compressor or the turbine isentropic efficiency results in an increase in the exergy destruction of the affected unit and can result in a decrease in the overall cycle performance. This is due to either an increase in power required by the compressor or a decrease in power produced by the turbine. The analysis suggests that the turbine isentropic efficiency has a greater impact on the net power generated than the compressor isentropic efficiency. Additionally, the turbine inlet temperature is a dependent variable as operating at different compressor pressure ratios and compressor isentropic efficiencies lead to varying turbine inlet temperatures. Therefore, increasing the turbine inlet temperature does not always lead to improved performance.

A Naive Bayes Classifier for Fault Detection and Classification Using Dimension Reduction Technique
Conference paperAbstract—Fault detection and classification is critical to the reliability of modern control systems in different industries, where detecting and classifying faults in operational processes are very important things while failure to detect and classify them, may cause irreparable damage. In this paper, fault detection and classification approach is presented. The first step, multi stage recursive least squares parameter estimation approach for controlled autoregressive autoregressive moving average systems (CARARMA) is developed with a view to estimate the parameters of the system, additionally, improve the effectiveness of the computation. By means of multi stage approach, the (CARARMA) system is decomposed into three simple identification models, and the parameters of each simple model is identified one by one. These parameters estimated by this approach are referred to as features, and not all of them have the same useful data about the system. In order to select the valuable features and improve a classification accuracy, the Linear Discriminant Analysis (LDA) approach based on scattering matrices is applied for dimension reduction. The classification between these reduced classes is done based on the Naive Bayes classifier. Finally, the obtained results explain the performance of this proposed approach.

Nutritional, Physicochemical and Organoleptic Properties of Cookies Enriched with Green Lentil Dietary Flour Proposed for Children
Journal ArticleThe aim of this study was to partially determine the nutritional and functional properties of cookies enriched with green lentil dietary flour proposed for children. The proposed cookies were enriched with lentil dietary flour at different concentrations, at the expense of the proportion of wheat flour. The cookies were divided into three different groups based on different formulas, the first group was without green lentil (control), while the other two groups were enriched cookies with green lentil flour “6%” and “12%”.
Results of protein analysis showed that cookies with 6% lentil flour had the highest protein content. Results of protein solubility indicated that cookies fortified with green lentil flour had the highest extraction values in comparison to the control samples. The molecular weight of proteins from ingredients (lentils, wheat, skimmed milk, whey protein, and egg), extracted by high ionic strength buffers, remained unchanged. The combination of ingredients normally impacts a change in proteins, but the major proteins preserve their nutritional characteristics even after being mixed in different formulas. The results showed that the dry matter and ash contents of cookie samples increased by the addition of lentil dietary flour. Colour measurement results showed that the control samples had the highest L* values, while samples of resulted in acceptable quality characteristics in both cookie types (6 and 12%). Overall, data indicates cookies enriched with green lentil dietary flour have fortified their protein and phytochemical contents. The utilization of protein powder derived from lentils may enhance the nutritional quality and functional properties of cookies that can be proposed for school and pre-school kids.

Optimizing Network Resilience with Segment Routing A Comparative Study of SR TI-LFA and rLFA
Conference paperAbstract: Network operators are confronted with the demanding requirements resulting from the evolution of IP networks. As a result, it has become necessary to provide rigorous Service Level Agreements (SLAs) that are in line with these requirements. However, traditional IP networks lack the necessary flexibility, scalability, and manageability to meet these demands. In order to address these limitations, the segment routing (SR) architecture has been developed. SR is based on source-routing and tunneling paradigms, which enable IP/MPLS and IPV6 networks to operate in a simplified and more scalable manner. The focus of this paper is on network protection (resiliency) using Topology Independent Loop-Free Alternatives Fast Re-Route (TI-LFA FRR) using MPLS as the underlying technology. SR overcomes the limitations of previous network protection mechanisms in terms of coverage and optimal path selection. To show the effectiveness of SR TI-LFA in comparison to its predecessor, Remote Loop-Free Alternate (rLFA), we have implemented various scenarios. These scenarios are designed to highlight the superior capabilities of TI-LFA.

Towards Net Zero Energy Buildings for Sustainability
Journal ArticleNet Zero Energy (NZE) buildings play a crucial role in meeting the Sustainable Development Goals (SDG) and creating environmentally friendly residential areas. These buildings are designed to generate as much energy as they consume, resulting in a net balance of zero energy consumption from the grid. By integrating innovative technologies and sustainable design principles, NZE buildings minimize their carbon footprint and contribute to a more sustainable future. The acquired result has been presented and discussed. The concept of Net Zero Energy Buildings (NZEBs) has gained significant attention in recent years as a crucial strategy for achieving sustainability in the built environment. NZEBs are designed to produce as much energy as they consume, resulting in a net energy balance of zero over a specified period.
