IAM RoadSmart
IAM RoadSmart formerly called the Institute of Advanced Motorists (IAM) is a charity based in the United Kingdom and serving nine countries, whose objective is to improve car driving and motorcycle riding standards, and so enhance road safety, by using the British police's system of car and motorcycle control commonly known as "the System". The System was devised in 1937 by racing driver Mark Everard Pepys, 6th Earl of Cottenham, to reduce accidents in police pursuits. People who have passed an IAM test have substantially fewer accidents and typically report getting more pleasure from driving too. Research has shown that IAM training increases a wide range of driving skills, including speed, safe distances, gear changing and cornering. The IAM was formed in 1956 and has over 82,000 members, all of whom have taken and passed an advanced test in a car, commercial vehicle or on a motorcycle. In 2006, the charity took over the work of the AA Motoring Trust, which had been established in 2002 by The Automobile Association. The charity brought its different activities and programmes together under one umbrella called IAM RoadSmart in 2016.

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.

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.

Digital Enhanced Cordless Telecommunications
Digital Enhanced Cordless Telecommunications (Digital European Cordless Telecommunications), usually known by the acronym DECT, is a standard primarily used for creating cordless telephone systems. It originated in Europe, where it is the universal standard, replacing earlier cordless phone standards, such as 900 MHz CT1 and CT2. Beyond Europe, it has been adopted by Australia , and most countries in Asia and South America. North American adoption was delayed by United States radio frequency regulations. This forced development of a variation of DECT, called DECT 6.0, using a slightly different frequency range which makes these units incompatible with systems intended for use in other areas, even from the same manufacturer. DECT has almost universally replaced other standards in most countries where it is used, with the exception of North America. DECT was originally intended for fast roaming between networked base stations and the first DECT product was Net3 wireless LAN. However, its most popular application is single-cell cordless phones connected to traditional analog telephone, primarily in home and small office systems, though gateways with multi-cell DECT and/or DECT repeaters are also available in many private branch exchange (PBX) systems for medium and large businesses produced by Panasonic, Mitel, Gigaset, Snom, BT Business, Spectralink, and RTX Telecom. DECT can also be used for purposes other than cordless phones, such as baby monitors and industrial sensors. The ULE Alliance's DECT ULE and its HAN FUN protocol are variants tailored for home security, automation, and the internet of things (IoT). The DECT standard includes the generic access profile (GAP), a common interoperability profile for simple telephone capabilities, which most manufacturers implement. GAP-conformance enables DECT handsets and bases from different manufacturers to interoperate at the most basic level of functionality, that of making and receiving calls. New Generation DECT (NG-DECT) standard, marketed as CAT-iq by the DECT Forum, provides a common set of advanced capabilities for handsets and base stations. CAT-iq allows interchangeability across IP-DECT base stations and handsets from different manufacturers, while maintaining backward-compatibility with GAP equipment. It also requires mandatory support for wideband audio.

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.

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.

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.

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.
