2. 1. User Preferred Trajectories in Commercial Aircraft Operation: Design and Implementation

   Author : Hanyo Vera Anders; Arthur Rizzi; Tobias Andersson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeronautics; air traffic management; aircraft operation; flygteknik; flygledning; Engineering mechanics; Teknisk mekanik;

   Abstract : This report describes how an aircraft creates and flies its User Preferred Trajectory from take-off to landing, based on the objectives and constraints the aircraft is subjected to from a technological and operational viewpoint. A basic description of commercial aircraft operation is given, with an emphasis on identifying the different stakeholders (Air Navigation Service Providers, Airline Operation Center, Pilot/Aircraft, Airport and Civil Aviation Authority).

4. 2. Buildings' Transition to Active Nodes: Assessing the Viability of DC Distribution, PV and Battery Storage

   Author : Patrik Ollas; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; Battery storage; Energy management; Solar photovoltaic; Direct current;

   Abstract : Historically, buildings have been passive nodes in the electric grid system with one-way power flows. However, with the recent market development of solar photovoltaic (PV) and stationary behind-the-meter battery storage systems, buildings are now transitioning to active nodes, offering bi-directional power flows.

5. 3. The Tail Assignment Problem

   Author : Mattias Grönkvist; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hybrid optimization; fleet planning; aircraft routing; column generation; airline optimization; tail assignment; constraint programming;

   Abstract : The Aircraft Assignment problem is the problem of assigning flights to aircraft in such a way that some operational constraints are satisfied, and possibly that some objective function is optimized.We propose an approach to aircraft assignment which captures all operational constraints, including minimum connection times, airport curfews, maintenance, and preassigned activities.

6. 4. Modeling Quantum Cascade Lasers : The Challenge of Infra-Red Devices

   Author : Martin Franckie; Matematisk fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum Cascade Lasers; Non-equilibrium Green s functions; Modeling; semiconductor heterostructures; Quantum Cascade Lasers; Non-equilibrium Green s functions; THz radiation; infrared radiation; semiconductor heterostructures; Modeling Simulation Technology; Fysicumarkivet A:2016:Franckié;

   Abstract : We live in a time of rapid scientific and technological advancement. People liv- ing 100 years ago could never dream of inventions like those having completely changed our way of life, and our perception of the world; computers, mobile phones, the Internet, space travel, unraveling the mysteries of the early universe and distant galaxies, and our insight into the microscopic world of quantum phe- nomena.

7. 5. Decision Models for the Procurement of Subsidised Air Services

   Author : Alan Kinene; Tobias Andersson Granberg; Valentin Polishchuk; Clas Rydergren; Svein Bråthen; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Small communities or remote regions are usually ignored by airlines because they have insufficient passenger demand and the air services to and from these regions are unprofitable. Free market conditions would lead to the lack of air connectivity to and from remote regions, hence transportation authorities intervene by procuring air services to guarantee improved accessibility for these regions.
