Rapid prototyping is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design (CAD) data. Construction of the part or assembly is usually done using 3D printing or "additive layer manufacturing" technology. The first methods for rapid prototyping became available in the late 1980s and were used to produce models and prototype parts. Today, they are used for a wide range of applications and are used to manufacture production-quality parts in relatively small numbers if desired without the typical unfavorable short-run economics. This economy has encouraged online service bureaus. Historical surveys of RP technology start with discussions of simulacra production techniques used by 19th-century sculptors. Some modern sculptors use the progeny technology to produce exhibitions. The ability to reproduce designs from a dataset has given rise to issues of rights, as it is now possible to interpolate volumetric data from one-dimensional images.

Rapid prototyping services will change the aerospace industry both on the ground as well as in orbit. In April of 2015, the engineers at the Space Flight Center finally received a box containing tools that were printed by a machine installed on the ISS (International Space Station) in space in the November of 2014.

They received a ratchet wrench, for example, which was designed on earth by Made in Space, which is a 3D printing company. The files for the design were sent to space electronically so that astronauts in the ISS could print them. Made in Space is currently collaborating with NASA in order to establish a rapid prototyping facility onboard the ISS.

From 14 different designs sent to them, 21 tools in total were printed, and they were then compared with tools that were printed from the same printer before, that is, before it was sent into space. The main goal is to determine how 3D printing is affected by microgravity, which was why project engineers subjected both the sets of instruments to tests of structure, durability, and strength using CT scans, structured light scanning, and electron microscopes.

Although the first tools that were printed in space were more of a test and won’t really be utilized in space, the main intention is to allow the astronauts to print parts that need replacing during outer space missions without needing to wait for supply missions to be sent form earth. Each 6-month operation from ISS operates over 200 science experiments at once, meaning that the ability to create any necessary tool or part quickly would save both money as well as time. That way, any emergency repairs that may be needed can be taken care of much more smoothly. In addition to that, NASA is also planning to try and recycle as much of the printing materials as possible while in space, which will eliminate the need of having to send any new material from earth, as sending a pound of equipment into space takes approximately $10,000.

What is email marketing? Basically the use of email to promote products and/or services. But a better email marketing definition is the use of email to develop relationships with potential customers and/or clients. Email marketing is one segment of internet marketing, which encompasses online marketing via websites, social media, blogs, etc. It is essentially the same as direct mail except that instead of sending mail through the postal service, messages are sent electronically via email.

Much of the spam email we all get proclaiming 'deals' on this, and that is a good example of email marketing at its worst; the mindless email barrage.

Someone somewhere buys an email list (or several!) and sends an email along the lines of “Get (the product name) for only (the amount) to everyone on the list – sometimes repeatedly. All this does is annoy everyone and give email marketing a bad name.

At its best, email marketing allows businesses to keep their customers informed and tailor their marketing messages to their customers.

Email Marketing Can Be Personalized

Particular groups of customers can be targeted or even individuals. Offering individual customers special deals on merchandise and/or services on the customer's birthday, for instance, is one example of email marketing personalization. (A restaurant might send an email to customers on their birthday offering 50% off an entree,) Email marketing helps a business develop and maintain a relationship with a customer over time that hopefully results in increased sales and increased customer loyalty.

Email marketing best practices include developing your own email list rather than buying an email list(s) and making participation in your email list opt-in rather than opt-out (using permission-based email marketing). Email should also be optimized for mobile usage as according to statistics over half of emails are opened on mobile devices.

An optical fiber or optical fibre is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables. Fibers are used instead of metal wires because signals travel along them with less loss; in addition, fibers are immune to electromagnetic interference, a problem from which metal wires suffer excessively. Fibers are also used for illumination and imaging, and are often wrapped in bundles so that they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope.Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber lasers.

Optical fibers typically include a core surrounded by a transparent cladding material with a lower index of refraction. Light is kept in the core by the phenomenon of total internal reflection which causes the fiber to act as a waveguide.Fibers that support many propagation paths or transverse modes are called multi-mode fibers, while those that support a single mode are called single-mode fibers (SMF). Multi-mode fibers generally have a wider core diameter and are used for short-distance communication links and for applications where high power must be transmitted.[citation needed] Single-mode fibers are used for most communication links longer than 1,000 meters (3,300 ft).[citation needed]

Being able to join optical fibers with low loss is important in fiber optic communication.This is more complex than joining electrical wire or cable and involves careful cleaving of the fibers, precise alignment of the fiber cores, and the coupling of these aligned cores. For applications that demand a permanent connection a fusion splice is common. In this technique, an electric arc is used to melt the ends of the fibers together. Another common technique is a mechanical splice, where the ends of the fibers are held in contact by mechanical force. Temporary or semi-permanent connections are made by means of specialized optical fiber connectors.

The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. The term was coined by Indian physicist Narinder Singh Kapany, who is widely acknowledged as the father of fiber optics.

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.

Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers - students, hobbyists, artists, programmers, and professionals - has gathered around this open-source platform, their contributions have added up to an incredible amount of accessible knowledge that can be of great help to novices and experts alike.

Arduino was born at the Ivrea Interaction Design Institute as an easy tool for fast prototyping, aimed at students without a background in electronics and programming. As soon as it reached a wider community, the Arduino board started changing to adapt to new needs and challenges, differentiating its offer from simple 8-bit boards to products for IoT applications, wearable, 3D printing, and embedded environments. All Arduino boards are completely open-source, empowering users to build them independently and eventually adapt them to their particular needs. The software, too, is open-source, and it is growing through the contributions of users worldwide.
