Poly (L lactic acid) (PLLA) ultrathin films of various thicknesses were prepared by spin coating method and investigated by using vibrational spectroscopic techniques such as FTIR and Raman. The analysis has been done in two parts: first one is verificati... see more

This paper details the design and implementation of a modulator-less beam steering transmitter based on a revised DDS-PLL phase shifter architecture. The proposed topology targets low data rate communications for Internet-of-Things systems, and has been d... see more

A current source control based PLL (phase lock loop) technique is one of the most efficient methods for modern 3F synchronized grid power systems. When an inverter circuit is driven by an electrostatic generator with wind power, it encounters some problem... see more

In most modern symmetric ciphers, substitution boxes are non-linear core components that provide robust security and confusion. The construction of active S-boxes has been hot object among safely experts. The goal is at build a cryptographically active S-... see more

In this paper, we analyze for the first time behavior in the time domain of the accumulated quantization error induced by the first- and second-order digital DeltaSigma modulator (DSM). The DSM is adopted in fractional-N PLLs to dither frequency division ... see more

Radio merupakan perangkat telekomunikasi yang mengirim gelombang elektromagnetik dimana gelombang ini merambat melalui udara. Perangkat radio terdiri dari komponen elektronika analog yang digunakan untuk mengolah sinyal secara sederhana serta memiliki kem... see more

Stasiun bumi merupakan suatu ground segment yang berfungsi sebagai pemancar dan penerima, ke dan dari satelit, untuk komunikasi data satelit, khususnya satelit nano. Stasiun bumi pada Tugas Akhir ini hanya berfungsi pada arah downlink saja, yakni hanya me... see more

Poly-L-Lactic Acid atau disingkat PLLA merupakan termoplastik biodegradable turunan dari sumber daya terbarukan. Kebutuhan dunia akan plastik yang terus meningkat diiringi dengan pencemaran lingkungan akan plastik yang juga terus meningkat, membuat PLLA m... see more

Poly-L-Lactic Acid atau disingkat PLLA merupakan termoplastik biodegradable turunan dari sumber daya terbarukan. Kebutuhan dunia akan plastik yang terus meningkat seiring dengan meningkatnya pencemaran lingkungan yang disebabkan oleh plastik. Hal ini memb... see more
