This paper proposes a model of Waveguide Photonic Band Gap (WPBG) structures, based on the Leaky Mode Propagation (LMP) method, to perform a complete analysis of electromagnetic (e.m.) wave propagation, including radiation loss, for a structure of finite extension. The LMP method allows for the detailed examination of the interaction between guided modes and radiative modes, providing insight into how energy leaks from the waveguide. This model enables the accurate prediction of both the confinement and loss characteristics of the WPBG structures, making it suitable for applications where both controlled wave propagation and minimized energy dissipation are crucial. Furthermore, we demonstrate the effectiveness of this approach through simulations and discuss its potential impact on the design of photonic devices.
The future is being built upon the foundation of renewable energy, particularly solar energy. Today, India is the third- largest solar deployment country in the world. Solar energy is an extremely efficient form of energy, making it a popular choice among people. However, the fixed structure of solar panels often limits their productivity. This paper proposes capturing more solar energy using a single-axis solar tracking system designed with an Arduino UNO and LDRs (along with two IR sensors). The proposed system aims to increase the performance of solar panels by continuously tracking the sun. It can receive the maximum amount of solar energy when it is perpendicular to the solar panel. The main controller in this paper is the Arduino UNO, a board based on the Atmega328P microcontroller. Two LDRs are used to detect the position of the sun in the sky, while a mirror rotates the orientation of the solar photovoltaic panels with the help of the L293D motor driver. An Arduino board connects to the sensor and gear drive. The photovoltaic panel and the motor are mechanically connected. The Arduino IDE is used to write the driver program. After the system was assembled, its operation was tested. The tracker intelligently adjusts the angle of the panels based on the direction in which the sun is facing the solar panel.
This paper presents a compact dual-band hexagon-rectangular shaped monopole antenna for WiMAX and WLAN applications. The miniaturized size of the antenna being 29 × 38 × 0.8 mm3. The proposed antenna operates efficiently within two distinct frequency ranges: 2.7 GHz to 3.2 GHz and 4.0 GHz to 5.1 GHz, addressing the needs of both WiMAX and WLAN systems. The antenna achieves bandwidths of 16.67% and 25.58% for the respective frequency bands, ensuring reliable performance and wide coverage for high-speed wireless communication. The antenna design attains its nature and application as a result of the center hexagonal shaped cavity which creates the required dual bands.
In the bloodstream, erythrocytes stand as vital carriers of oxygen and carbon dioxide, facilitated by the presence of hemoglobin within their structures. However, deviations in erythrocyte size can lead to the formation of Poikilocyte cells, a characteristic feature of conditions like Iron Deficiency Anemia. Variants of Poikilocytoses, such as Degmacyte, Dacrocyte, Schistocyte, and Elliptocyte, denote distinct alterations in erythrocyte morphology, often associated with diminished iron levels crucial for haemoglobin synthesis. In a recent study, the differentiation between normal RBCs and Poikilocyte cells has been addressed through the application of Artificial Neural Network (ANN) algorithms, leveraging extracted features from digital images of blood smears. This approach offers a more precise means of identifying blood disorders compared to traditional visual inspection, utilizing image analysis techniques to detect deviations in color, size, and statistical parameters. The methodology involves a series of computational steps including preprocessing, segmentation, morphological operations, feature extraction, and classification, all executed within the Matlab environment. Furthermore, to enhance diagnostic capabilities, the system integrates glucose level measurement alongside erythrocyte analysis, transmitting data to a controller which relays results via GSM signal as SMS and LCD display. This comprehensive approach not only automates cell identification and classification but also ensures efficient and accurate analysis, including the automated separation of overlapped cells.
The conventional planar Metal-Oxide-Semiconductor FETs (MOSFETs) are being replaced with Fin Field-Effect Transistors (FinFETs) due to their improved ability to manage power dissipation, propagation delay, leakage current, and short channel effects. Process variability is an issue for planar MOSFETs, however the amount of dopant ions in FinFETs reduces device performance variability. In this study, a Static-Random Access Memory (SRAM) cell employing FinFET technology is designed using three MOS transistors. It is composed of two NMOS plus a single PMOS transistor. One NMOS acts as access transistor while the pull-up and pull-down functions are performed by remaining NMOS and PMOS transistors, respectively. The proposed SRAM cell is simulated using H-SPICE simulator and is compared with existing SRAM cell designs in terms delay, power consumption and transistor count. Performance analysis shows that the proposed SRAM Cell overcomes the constraint and achieves full swing storage of logic values between 0 and 1. This justifies the definition of static. Implementing a single-ended SRAM cell also has the benefit of simplifying the SRAM cell architecture, which also results in a reduction in area.
