AR Technologies in Engineering Education
Over the past decade, the use of AR has significantly increased over a wide range of applications. Although there are many good examples of AR technology being used in engineering, retail, and for entertainment, the technology has not been widely adopted for teaching in university engineering departments. It is generally accepted that the use of AR can complement the students’ learning experience by improving engagement and by helping to visualise complex engineering physics; however, several key challenges still have to be addressed to fully integrate the use of AR into a broader engineering curriculum.

Air Source Heat Pumps
An air source heat pump (ASHP) is a system that transfers heat from outside to inside a building, or vice versa. Under the principles of vapor compression refrigeration, an ASHP uses a refrigerant system involving a compressor and a condenser to absorb heat at one place and release it at another. They can be used as a space heater or cooler, and are sometimes called "reverse-cycle air conditioners". In domestic heating use, an ASHP absorbs heat from outside air and releases it inside the building, as hot air, hot water-filled radiators, underfloor heating and/or domestic hot water supply. The same system can often do the reverse in summer, cooling the inside of the house. When correctly specified, an ASHP can offer a full central heating solution and domestic hot water up to 80 °C.

OPALS
Optical PAyload for Lasercomm Science (OPALS) is a spacecraft communication instrument developed at the Jet Propulsion Laboratory that was tested on the International Space Station (ISS) from 18 April 2014 to 17 July 2014 to demonstrate the technology for laser communications systems between spacecraft and ground stations. The purpose of OPALS is to do research into replacing traditional radio-frequency (RF) communications which are currently used on spacecraft. This will allow spacecraft to increase the rate at which data is downlinked by 10 to 100 times. It also will have less error than RF communication. It launched from Cape Canaveral Air Force Station to the ISS on 18 April 2014 on a Falcon 9 SpaceX CRS-3 Dragon capsule resupply.

Ghost Gun
A ghost gun is a term for a (typically) homemade firearm that lacks commercial serial numbers. The term is used mostly in the United States by gun control advocates, gun rights advocates, law enforcement, and some in the firearm industry. Because home-manufacture of firearms for personal use is not considered to fall under the federal government’s authority to regulate interstate (as opposed to intrastate) commerce, individuals making their own firearms are not subject to federal or state commercial background check regulations. Persons otherwise prohibited from owning firearms are still legally barred from the manufacture, transfer, or possession of firearms or ammunition, regardless of the method of manufacture or acquisition.

Picture Exchange Communication System
The Picture Exchange Communication System (PECS) is an augmentative and alternative communication system developed and produced by Pyramid Educational Consultants, Inc. PECS was developed in 1985 at the Delaware Autism Program by Andy Bondy, PhD, and Lori Frost, MS, CCC-SLP. The developers of PECS noticed that traditional communication techniques, including speech imitation, sign language, and picture point systems, relied on the teacher to initiate social interactions and none focused on teaching students to initiate interactions. Based on these observations, Bondy and Frost created a functional means of communication for individuals with a variety of communication challenges. Although PECS was originally developed for young children with autism spectrum disorder (ASD), its use has become much more widespread. Through the years, PECS has been successfully implemented with individuals with varying diagnoses across the aged span. PECS is an evidence-based practice that has been highly successful with regard to the development of functional communication skills.

Use of Bio-Inspired Design Tools by Industry Professionals
Bio-inspired design (BID) has the potential to evolve the way engineers and designers solve problems. Several tools have been developed to assist one or multiple phases of the BID process. These tools, typically studied individually and through the performance of college students, have yielded interesting results for increasing the novelty of solutions. Human-centered design (HCD) and “design thinking” have become standard practice in consumer-product design and development. Now, it is common for industrial designers, engineers, and product managers to be conversant in the process and methodologies of HCD.

Deformable Mirror
Deformable mirrors (DM) are mirrors whose surface can be deformed, in order to achieve wavefront control and correction of optical aberrations. Deformable mirrors are used in combination with wavefront sensors and real-time control systems in adaptive optics. In 2006 they found a new use in femtosecond pulse shaping. The shape of a DM can be controlled with a speed that is appropriate for compensation of dynamic aberrations present in the optical system. In practice the DM shape should be changed much faster than the process to be corrected, as the correction process, even for a static aberration, may take several iterations. A DM usually has many degrees of freedom. Typically, these degrees of freedom are associated with the mechanical actuators and it can be roughly taken that one actuator corresponds to one degree of freedom.

Spiral Ground Heat Exchanger
Spiral ground heat exchangers in heat pump applications play an important role in heating/cooling of buildings. Energy consumption of buildings is a significant factor in global environmental issues. One of the ways of supplying heating and cooling is using potential energy stored in the ground which is clean and sustainable. These types of systems are called ground source heat pump (GSHP) systems. The initial cost and efficiency of GSHP systems can be influenced by optimal design of ground heat exchangers (GHEs). Many parameters influencing thermal performance of spiral GHEs such as external major diameter of borehole, spacing, distance between each turns of spiral GHEs, etc. When we have a large application area, one spiral GHE is not enough for supplying heating or cooling demands of the building. In this case more than one GHE is needed to be embedded into the ground. When we have more than one GHE in ground, optimization of distance between them becomes an essential problem. Another important parameter which is highly affecting thermal performance of a GSHP system are thermal properties of ground. Before integrating a GSHP system to the building thermal properties of ground or soil should be determined.

ESA Round Robin Exercise
Motivated by the experience acquired in the ESA promoted Round Robin exercise aimed at comparing cloud detection algorithms for PROBA-V sensor, we investigate specific issues related to cloud detection when remotely sensed images comprise only a few spectral bands in the visible and near-infrared by considering a bunch of well-known classification methods. First, we demonstrate the feasibility of using a training dataset semi-automatically obtained from other accurate algorithms. In addition, we investigate the effect of ancillary information, e.g., surface type or climate, on accuracy. Then we compare the different classification methods using the same training dataset under different configurations. We also perform a consensus analysis aimed at estimating the degree of mutual agreement among classification methods in detecting Clear or Cloudy sky conditions. Results are also compared on a high-quality test dataset of 1350 reflectances and Clear/Cloudy corresponding labels prepared by ESA for the mentioned exercise.
