the objective of the present field experiment was to examine how plant density and enhanced source, i.e. thinning treatments, may affect grain yield and its components for a non-prolific maize hybrid, sc704. the environment of the hybrid maize crop was changed at intervals over its life cycle by removing every other plant in rows equispaced at 75 cm apart with a population of 13.34 plants m...

This paper presents a study of the contact resistance between metal M (M = Ni, Pt, and Au) an array n-type Bi2Te3−xSex thermoelectric nanowires deposited through electrodeposition process in alumina membrane. Contact resistances different metals have been tested characterized after optimization mechanical thinning polishing top part A low areal 87 µΩ cm2 obtained with Au as electrode is very en...

In this paper, we report an integrated silicon-based active imaging chipset with a detector array in 0.13 m SiGe process and a CMOS-based source array operating in the 240–290 GHz range. The chipset operates at room-temperature with no external RF or optical sources, high-resistivity silicon lenses (HRSi) or waveguides or any custom fabrication options, such as high-resistivity substrates or su...

This paper presented a compressive sensing (CS) calibration technique that simultaneously measures all the element excitations of 2×2 active phased antenna array (APAA) instantaneously. The power patterns rectangular APAA are synchronized to orthogonally cross multiplicative sub-array system applying in achieving an thinning along two 1-D sub-arrays for fixed steered beam radiation. far field r...

Abstract: Sudoku puzzles, often seen in magazines and newspapers, are logic-based challenges where each entry within the puzzle is comprised of symbols adhering to row, column and box constraints. Previously, we had investigated their potential in frequency-hopped waveforms to achieve desirable radar ambiguity functions and compared them with random, as well as the more familiar Costas sequence...

In this paper, the authors present an optimization method based on modified Particle Swarm Optimization (PSO) algorithm for thinning large multiple concentric circular ring arrays of uniformly excited isotropic antennas that will generate a pencil beam in the vertical plane with minimum relative side lobe level (SLL). Two different cases have been studied, one with fixed uniform inter-element s...

This novel work has considered the problem of minimizing side lobe level linear array antenna patterns using concept thinning. In comparison to all element arrays, thinning approach activated only a fraction portion total available number elements at suitable positions achieve objectives. The been transformed into constrained optimization with objective while simultaneously satisfying desired a...

generally, fruit trees should produce sufficient yield annually through their economic life. fruit trees usually produce flowers over their ability of productivity. if all of the flowers are converted to fruit, the tree will be weak and poor smaller fruit will be produced and it may cause alternate bearing. thus some flowers must be removed by hand, mechanically or chemically. in this study, th...
