Drone technology has advanced to the point where unmanned aerial vehicles (UAVs) can perform complex, autonomous functions. Drones are now used in many areas of aviation beyond military applications. This document discusses drone technology, including advantages like their ability to access dangerous environments and film wildlife easily, as well as disadvantages such as limited battery life and vulnerability to weather. Formulas are presented for calculating drone thrust and weight. The scope of drone technology is categorized into how it impacts customers, service providers and society.

1- AL JOHARA
In 1994 the European Channel Tunnel was opened, and it linked the European continent and Britain. It is a 31-mile tunnel carrying freight trains and Eurostar trains between Paris and London and is today considered the fast and modern transport institution. Although the tunnel traces its background to the 19th century, it is considered an achievement of the 20th century (Syon, 2008).
Though the project has been credited to be a success, the size of the channel had intrinsic uncertainties and risks. Tunneling projects are naturally high risk and often end up in high overrun on budget and completion dates due to the underground setting that were not anticipated during the contract (Syon, 2008). The risks present in the Chunnel project were design and construction challenges brought about by the changing geological situations, the third-party issues, the safety of the workers, infrastructure/property damage and environmental risk (Berend, 2016). In Britain there was no space for disposing of spoil and emission of waste became a significant challenge. Though there was a mitigation of disposing spoil in the Coast, some critiques were of the view that it would destroy the environment. The risk of the tunnel collapsing due to earthquakes was a concern to many individuals; however, the tunnels had a design which ensured they were resistant and caution was taken to reduce possibility of damage to equipment installed in them and to make sure entrances couldn’t be blocked by local collapses and landslips (Pireddu, 2017).
Technological risks were experienced in the construction of the tunnel. These include the political and economical viability of the machinery that were required to ensure the project goals were achieved. In the Chunnel tunnel, this risk was mainly assumed by the contractor, Eurotunnel. All the technological risks involved were mitigated by the comprehensive geological research of the strata of where the tunnel was to be constructed (Berend, 2016). Earlier concerns demanded the state of the art equipment which were costly and afterward found unnecessary. The political risks were mitigated by assigning the task to a private investor after the conservative and left-wing reign in Britain (Pireddu, 2017).
The project further experienced credit risk. The risk calculated on the basis of the investor’s creditworthiness. Unlike other mega-projects which are normally funded by the government, the Channel tunnel was private-funded and therefore presented a high risk to the contractors and investors. Most private investors were giving a small fraction of the total approximation cost. The administration for example under credit limitation had to suggest lump-sum contracts, which were impractical for such projects. Litigation and claims at the end of the project were experienced (Berend, 2016).

Development of a Integrated Air Cushioned Vehicle (Hovercraft)IJMER
The design and development of a hovercraft prototype with full hovercraft basic functions is
reported by taking into consideration, size, material and component availability and intermediate
fabrication skill. In-depth research was carried out to determine the components of a hovercraft
system and their basic functions and in particular its principle of operation. Detailed research in design
was done to determine the size of component parts, quite in accordance with relevant standard
requirements as applicable in the air cushioned vehicles (ACV). The fabrication of the designed
hovercraft by using materials that are readily available by taking into consideration the economic
constraints and time constraints. It also includes the testing process which includes the tweaking of
various parameters that govern lift and thrust of the hovercraft. Further research is recommended to
improve on the efficiency of the craft.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

2. • A DRONE AS AN AIRCRAFT THAT FILES
WITHOUT A CREW ON BOARD
• IN THE 21ST CENTURY, TECHNOLOGY REACHED A POINT OF
SOPHISTICATION THAT THE UAV IS NOW BEINGGIVEN A GREATLY
EXPANDED ROLE IN MANY AREAS OF AVIATION
INTRODUCTION
• A UAV is capable of controlled, sustained level
flight and is powered by a jet.
3. FORMULA
Quadcopter drone weight 800g in
total and you choose a thrust-to-
weight ratio of 4:1 Using the drone
thrust formula
Thrust=(4/1)*800=3200 g,
Thrust per motor=3200 g/4= 800
g.
Time = Capacity * discharge/AAS
Weight = 35*9,81 = 343 N.
4. SCOPE OF THE TECHNOLOGY
The scope of drone technology can be categorized into three perspective:
• CUSTOMER
• SERVICE PROVIDER
• SOCIETY
5. ADVANTAGES
• Surpassing the traffic
• Used in dangerous environments’
• Environment friendly
• Using natural energy
