Viability of Drones application as a future logistic transport method:

We need someone with experience on drones application, to prepare a document with a study of “Viability of Drones application as a future logistic transport method”. It starts with an introduction of the topic and the types of drones. this is followed by a series of challenges that have to be faces. here the risks, consequences and some possible mitigations, solutions and alternatives are discussed. next we look at the advantages. Then several viable options are discussed, we discuss situations where the advantages can be used, and the challenges are minimized. finally we conclude that drones are a great way to enrich the logistics and transportation sector, but not replace current systems.

Viability of Drones as a logistic transport method

The following topics are coverd in this paper: Sound Waves; Basics of Wave Reflection; Standing Waves; Harmonics; Pipe Resonance; Conical Frustum Resonance ; End Correction; Hemholz Resonator; Resonance of a Sphere; Acoustical Impedance.

Physics paper I: Acoustic Resonance

Create invoice system in excel: I created a layout in a template file and automated everything using VBA. The used just uses two user-forms. one for the client information +invoice number and one to add items to the invoice. Using a combination of VBA and basic excel functions everything else is automated. adding items, adding pages, calculating VAT, totals, adding page information, adding payment information. It will also catch any missing or wrong user input and prompt the user to fix his.her input in the user forms.

Fourier series, Fourier transforms and FFT. These topics are covered in an intuitive manner, using visuals and examples to illustrate the mathematics.

mathematics paper III - Fourier transforms

$The paper covers Trigonometry, Exponents, Complex numbers and Euler\\\'s formula. It is a prelude to another paper on Fourier Transforms. Although a technical paper, the goal is for the user to understand the use of the material, not just memorize formulas. it takes the reader on a mathematical journey, describing the history, applications and techniques as well as provide real world examples.$
