At TUS Nordics 2017, Anders La Cour-Harbo gave the presentation ‘Are you likely to be hit by a drone?’ in our Security & Safety track, on Thursday 12 October 2017.
The document discusses using a full flight simulator (FFS) to conduct cost-effective research on a new fleet of AW139 helicopters for New South Wales helicopter emergency medical services (HEMS). The FFS would allow for integrated simulation of responses in the front and back of the aircraft to different medical situations. It would also enable accurate reproduction of past real-life incidents to evaluate how crews might handle the same tasks on different aircraft, helping draw powerful conclusions while minimizing risks to crews evaluating a new aircraft.
Digital Power: A Journey to Direct Channel GrowthJason Glenn
We define the biggest digital problem that today's airlines face: their considerable brand power does not translate into digital power. In this presentation you will learn how we define digital power and the steps each airline can take on the journey towards growing their direct channel.
The abacus, one of the earliest calculators dating back 2500 years to Asia Minor, was based on the human hand and used beads to perform calculations. In the 17th century, Wilhelm Schickard created a machine that could add and subtract 6-digit numbers using a rotating wheel. Gottfried Leibniz then developed the first calculator that could perform all four basic arithmetic functions using a stepped drum mechanism. Throughout the 19th and early 20th centuries, various inventors developed new calculating machines with full keyboards and printing capabilities to help with calculations in businesses. Konrad Zuse then created the first binary computer in 1936 using metal plates for memory instead of chips. This led to the development of the microprocessor and modern calcul
The document discusses renewable energy sources that could help solve Bangladesh's energy crisis and support sustainable development. It outlines various renewable sources available in Bangladesh including solar, wind, biogas, biodiesel, micro hydro, ocean wave, tidal, and geothermal energy. These sources have good potential to generate electricity and help meet the country's growing energy demands if developed further with support from the government and private sector. Renewable energy could also improve rural livelihoods and allow Bangladesh to export excess power in the future.
Projectors work by using different technologies to project images or video onto a screen. The main types are CRT, LCD, DLP, and LCOS. CRT projectors use electron guns and phosphors to create images. LCD projectors use backlights and liquid crystal panels to control light transmission for each pixel. DLP projectors use an array of microscopic mirrors to rapidly reflect light and form images. LCOS projectors are similar to LCD but use reflective silicon backplanes instead of glass for better image quality. All projector types work by precisely controlling light to reproduce colors and create projected pictures.
Solar energy can be harnessed using technologies like solar heating, photovoltaics, and concentrating solar power. There are two main types - passive solar, which uses sunlight without external mechanical power, and active solar, which uses mechanical or electrical power. Solar energy can be directly converted to electricity via photovoltaic panels or indirectly via solar thermal collectors that capture heat. Large solar power plants use thousands of solar panels or mirrors to generate electricity on a utility scale. Solar energy can be stored using batteries in off-grid homes or by feeding excess electricity to the grid via net metering.

Rural electrification using PV: Success Story of BangladeshMarufa Mithila
Rural areas in Bangladesh have low electrification rates, with only 30% of rural households having access to grid electricity. To address this, Infrastructure Development Company Limited (IDCOL) launched a solar home system program in 2003 to provide electricity to rural areas using solar PV. Over 1.65 million solar home systems have now been installed under the program, accounting for 98% of solar home systems in the country. The program aims to install 4 million systems by 2015 to supply electricity to more rural households in Bangladesh.
This presentation summarizes the proposed Rampal Power Station project in Bangladesh. It will be a 1320 megawatt coal power plant located near the Sundarbans mangrove forest. The project is a joint venture between Bangladesh and India, with funding from loans and both countries. However, environmental groups oppose the project's location due to concerns it will damage the fragile ecosystem and wildlife of the Sundarbans. The presentation explores the project details, financing, agreements, government support for the project despite environmental issues, and calls to relocate the project to protect the UNESCO World Heritage site.
Study on solar irrigation system in bangladeshTania Marzia
This document summarizes a study on solar irrigation systems in Bangladesh. It discusses how agriculture is important to Bangladesh's economy but irrigation is challenging due to water scarcity. Currently, irrigation is powered by conventional electricity or diesel generators. The study proposes using solar power as a more cost-effective solution for irrigation. It describes different types of solar irrigation systems and notes that solar is most competitive for low-pressure irrigation needs. Present solar power generation in Bangladesh is around 15-20 MW but there is potential to increase irrigation powered by solar.

This document describes how to build a simple mouse trap car using wood, tape, a mouse trap, string, and glue to demonstrate that the car will move when the mouse trap snaps. Instructions are provided to glue together pieces of wood to form the body and axles of the car, attach wheels, secure the mouse trap to the center, and tie a string between the trap and front of the car so that when the trap snaps, it will pull the string and cause the car to move forward, proving the concept. The experiment was a success, as the car moved as predicted when the trap snapped.
An electronic scientific calculator is considered an embedded system because in addition to performing calculations, it handles low-level functions like input from keys and output to displays. Scientific calculators contain microchips that allow them to perform complex math operations quickly and accurately. They are used in fields like engineering and physics where advanced math is needed. Modern calculators have keyboards, LCD screens, and batteries or solar cells as their main components.
The document discusses the future potential of solar power in Bangladesh. It outlines that solar power could help electrify rural villages not connected to the national grid. Bangladesh receives a high amount of solar radiation throughout the year, with an average of 5.5 kWh/m2/day. This provides strong potential for solar energy development. Solar power would have advantages for Bangladesh as the sun is a free and pollution-free energy source, and solar technology is becoming more cost-effective. The government could help develop solar power by using solar panels on barren lands and installing solar street lights.
This document presents information from a student presentation on solar cells. It includes the names of the three presenters, an outline of topics to be covered, definitions of solar cells and how they work as solid-state electrical devices that convert light to electricity, descriptions of different photovoltaic technologies and applications, the components of solar systems, and materials used in various types of solar cells like monocrystalline silicon, polycrystalline silicon, and multi-junction cells.
Numerical analysis of Vertical Axis Wind Turbinehasan47
This document summarizes a numerical analysis of a vertical axis wind turbine conducted by researchers at Khulna University of Engineering & Technology in Bangladesh. The researchers used computational fluid dynamics to model the turbine and analyze performance parameters. They generated a mesh model of the turbine blades and airfoil and simulated rotation using a sliding mesh technique. The analysis found that the turbine achieved an optimal power coefficient of 0.34 at a tip speed ratio of 4.5. The results of the numerical study could help with practical implementation of vertical axis wind turbines.
This document provides information about gas turbines, including:
- The basic components and working mechanism of a gas turbine, including the compressor, combustor, and turbine.
- Details on the Brayton cycle that gas turbines use.
- Descriptions of key components like the axial compressor and reverse-flow combustor.
- Applications of gas turbines in power generation systems like combined cycle and cogeneration plants.
- Performance variables that affect gas turbine efficiency like ambient temperature and exhaust temperature.
Gas turbines operate using the Brayton cycle, which involves compressing air, adding heat through combustion at constant pressure, expanding the hot gases through a turbine, and rejecting heat at constant pressure. Early gas turbines had low efficiency around 17% but efficiency has increased through higher turbine inlet temperatures, more efficient components, and modifications like regeneration, intercooling, and reheating. Regeneration improves efficiency by heating the compressed air with the turbine exhaust, while intercooling and reheating involve multistage compression and expansion with cooling or heating between stages. Open cycle gas turbines exhaust combustion gases while closed cycle models re-circulate gases, improving efficiency but requiring more complex components.
The document discusses various alternative energy sources including solar energy. It provides advantages and disadvantages of solar energy, wind energy, clean coal technology, fossil fuels, geothermal energy, hydro power, and nuclear energy. For solar energy specifically, it notes that the sun is the most abundant energy source, solar panels can be used to collect energy, and energy storage methods exist. However, solar energy also has high initial costs and can only generate energy during the day.

Safety in Aviation Transportation
Facts
• The Wright Brothers (1903), were the first to complete the first ever assisted take off, pioneering the age of powered and controlled air travel. The first extensive use of heavier than air engine powered planes was seen a decade later in the First World War.
• During the 1920s and 1930s, advancements in air transport saw the first commercial airliner, the Douglas DC-3, transport passengers safely.
When the Second World War was taking place, most cities were building airports, and the popularity of air transport increased after the war
• Air transport over the years has come to be referred to as the safest way to travel. During the Second World War, fatalities by aircraft crash increased sharply. After the war, approximately 300 crashes were reported per year until 1980. That is equivalent to about 2000 deaths per year.
• The years from 1970 saw a steady decline in aircraft accidents due to enhancements in technology and safety procedures. For example, in 1973, the FAA in the USA introduced the screening of passengers and their luggage. Since the year 2000, there have been averagely 164 aircraft crashes per year resulting in 1061 deaths (Kirk). According to the IATA, more than 3.5 billion people flew safely on 37.6 million flights in 2015. According to B3A, in the same year, 122 aircraft crashes occurred worldwide leading to 898 deaths.
• 2016 was the safest year to travel by air. Only five fatal aircraft incidences were reported. These include the Egyptian flight that crashed into the Mediterranean in May leading to 66 deaths and the Brazilian LaMia jet carrying a popular football team in November killing 71 people. to70, an international air transport consultancy firm based in the Hague reported that only 271 deaths by plane crash occurred in 2016 (Calder)
• Data collected by professor Ian Savage of the department of economics at Northwestern University shows that regarding deaths per billion passenger miles traveled, air travel accounts for 0.07 deaths. This is a small value as compared to other modes of transport. Motorcycles are the most unsafe with 212.57 deaths followed by cars at 7.28 deaths per one billion passenger miles traveled.(Morris)
• Aircraft accidents are rare as compared to other forms of transport but on occurrence seem relatively fatal. This fatality is then exaggerated by the media creating an assumption that air transport is more dangerous than it is(Hope)

The Intersecting Operations (IO) Model was developed to define a set of separation standards for converging and intersecting runway operations which statistically mitigates collision risk for modeled airport geometries and associated parameters. The IO Model incorporates synthetic trajectory models that account for the variation within historical environmental variables and actual flight data informed by NOP and ASDE-X sources. This model provides a simulation by which analysts can statistically determine an area of unacceptable risk and propose a risk mitigation methodology for these areas.

White Paper - Countering Drones at Airports 2019 by DGSDanielCHOU25
Current rise in the popularity of drones have caused a surge in aircraft-drone near-miss events and raised the risks of drone air traffic disruptions. Several anti-drone technologies exist which can put an end to the menace. While monitoring is encouraged, drone neutralization methods are still not legally allowed in several countries. Typical monitoring tech equipment include RF Analyzers, Radar, Cameras and Acoustic Systems. They all come with their own pros & cons.
Two studies examined aircraft self-separation from the perspectives of pilots and air traffic controllers. Increasing traffic density led to longer detection times for conflicts and higher workload ratings. Pilots focused their attention on cockpit displays rather than outside views. Future research could explore abnormal situations and data link communications to understand their impacts on self-separation.
This document discusses heterogeneous aircraft use of airspace and the effects on accident investigation. It describes two mid-air collisions involving different types of aircraft - a helicopter and small plane collision over New Jersey in 2009, and a collision between a small plane and medical helicopter in Virginia in 2010. Both accidents highlighted limitations of visual "see and avoid" procedures when operating diverse aircraft in close proximity. The document also provides context on airspace classifications in the U.S. and regulatory efforts to safely integrate new aircraft like unmanned aerial systems into the national airspace system.
Drones are becoming more popular for both personal and commercial use, but their increasing presence also poses risks to commercial aviation safety. The director of IATA called drones a "real and growing threat" to airplanes and cited several near-misses between drones and airliners. While companies like Amazon see opportunities in drone delivery services, regulators are concerned about drones interfering with air traffic, especially around airports. Many countries are establishing rules for drone use, such as registration requirements, but there are disagreements over how much regulation is needed versus restricting innovation. The article concludes that rules are needed to allow drone usage while preventing interference with aviation to achieve a balance of innovation and safety.

Use of UAS for Domestic Border Security Operations in the United States
Student no. 3
9 November 2019
The use of UAS and or UAV for ISR has been in existence since the 19th century.U.S CBP agency is no exception since it has various assets in its arsenal of ISR to protect the U.S borders, with one example being the use of UAS. The one safety concern for the public is the integration of UAS into the domestic airspace (Cho, 2014).
Summary
The CBP has an arsenal of ISR assets to use to protect our borders from fixed-wing aircraft like the Beechcraft King Air Series 200 and C-12C, Cessna C-206/210 and C-55 Citation, to rotary-wing aircraft like the Airbus AS350 A-Star, Bell UH-1H Huey II, Sikorsky UH-60, to marine vessels like 39-foot Interim Midnight Express, 33-foot SAFE Boat, a Tethered Aerostat Radar System, and UAS MQ-9B Predator along with small unmanned aerial systems (sUAS) to name a few, but what has the public concerned is the unmanned aerial systems of the MQ-9B Predator and sUAS (Air and Marine Operations Assets, 2019). Since most of these assets are manned aircraft or vessels which are piloted from within, with the exception of the Tethered Aerostat which is stationary balloon, the MQ-9B Predator and sUAS are systems that are pilotless in the sense that the pilot is flying it form the ground far away from it. This leads to concerns of the safety aspects of flying this UAS along with other aircraft in the NAS.

The CBP currently has a fleet of nine MQ-9 Predator B’s that are on regular surveillance missions looking for illegal activity crossing the Southern border (Bier & Feeney, 2018) The MQ-9B Predator, manufactured by General Atomics Aeronautical systems, is used for its vast operational capabilities, unique payload, mission flexibility, and that it can be fitted with new applications along with an excellent safety and performance record with other agencies (Unmanned Aircraft System, 2019).
Significance of Issue
The CBP have recently completed testing the use of sUAS and are currently implementing them for operational use in the field to complement their current inventory of manned and large UAS aircraft.The UTM still in its infancy of being tested and developed it brings up another safety issue with smaller unmanned aerial systems or vehicles being operated in the same airspace as low flying aircraft.
Significance of Issue
The United States, according to a CRS Report for Congress, has approximately 19,937.4 miles of International boundaries that the CBP covers on a day to day basis (Beaver, 2006). The extended range and endurance of these UASs may reduce the burdens on human resources at the borders. Like all other borders, the United States requires 24-hour surveillance of its borders on land and on our coastline.
Research and Development
The use of sUAS in the field in place of the large UAS MQ-9B Predator has given some additional adva ...
The document discusses regulations for the civil applications of unmanned aerial vehicles (UAVs). It provides an overview of UAV types and applications, both military and civil.

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
