Block SLM Scheme for Efficient PAPR Reduction in OFDM Systems
Abstract: AbstractOrthogonal frequency division multiplexing (OFDM) is an attractive technique due to its high-speed data transmission and robustness for time-selective channels. However, the major drawback of OFDM system is high peak-to-average power ratio (PAPR). In this paper, two PAPR reduction schemes have been introduced; one is conventional selected mapping (SLM) scheme and a new proposed block selected mapping (BSLM) scheme to obtain PAPR reduction performance in OFDM system. In the proposed …

Influence of Dielectric and Active layer Thickness on MgZnO Thin Film Transistor Electrical Characteristics
Abstract: From last decades, Thin Film Transistors Technology uses low-k dielectric material as an insulator. Insulator thickness plays an important role in device dimension. The insulating layer also known as the gate oxide separates the gate electrode from the channel region of the transistor. If the insulating layer is too thin, there is a greater chance that electrons can tunnel through the oxide layer, leading to leakage current. To mitigate this …

The drying characteristics of bitter and sour sop leaves are affected by temperature
Abstract: One of the earliest techniques for food preservation is the drying method. Drying is important because it reduce the moisture content of the food hence reducing the breeding ground for microorganism that causes food spoilage. Due to this marked effect, the study was aimed at investigating the effect of temperature on the drying characteristic of bitter leave (Vernonia Amygdalina) and Soursop (Annona Muricata). The methodologies employed in this researches are …

An Efficient Synthesis of Some Novel Benzo Coumarin Derivatives Under Solvent Conditions from 2-acetyl-benzo[f]chromen-3-one
Abstract: The synthesis of the target compounds began with the preparation of 2-[3-dimethylamino[acryloyl-3H-benzo[f]chromen-3-one. This intermediate was obtained through the reaction of 2-acetylbenzo[f]coumarin-3-one with N,N-dimethylformamide dimethyl acetal [DMFDMA[ under reflux conditions in xylene. The enaminone thus formed was subsequently reacted with 6-aminothiouracil in acetic acid, leading to the formation of 2-thioxo-2,3-dihydro-1H-pyrido[2,3-d]pyrimidin-4-one. This compound served as a pivotal intermediate for the synthesis of a series of pyridotriazolopyrimidinones. These derivatives were synthesized by reacting …

Analysis of Tall Structures for Different Stiffness Ratios of Columns to Shear Walls and Column Shortening
Abstract: Differential axial shortening in a structure causes axial force redistribution among columns and walls, and introduces additional forces in the horizontal members such as beams and slab. Hence, it needs to be considered in the design, especially for medium to high-rise buildings. The best way to illustrate differential column shortening is to conduct floor-by-floor analysis, generally known as construction sequence analysis. Commercial software ETABS is available for conducting sequential analysis. …
