Eryx (Missile)
Eryx is a short-range portable SACLOS-based wire-guided anti-tank missile (ATGM) produced by European company MBDA. It is used by several countries, including the Canadian Army, French, and Norwegian armies. The weapon can also be used against bunkers and pillboxes. It also has some capability in the anti aircraft role to bring down low flying helicopters, due to its wire-guided system. An agreement was reached in 1989 between the French and Canadian governments to co-produce the Eryx missile system. It entered service in 1994.

Bicycle Touring
Bicycle touring is the taking of self-contained cycling trips for pleasure, adventure or autonomy rather than sport, commuting or exercise. Touring can range from single-day trips, to multi-day trips, to years. Tours may be planned by the participant or organised by a holiday business, a club, or a charity as a fund-raising venture.

Polymer-Based Additive Manufacturing
Numerous publications are available in relation to several strategies for Design for Additive Manufacturing (DfAM). Achieving a very high degree of complexity and detail in a final product has become a possibility that has led to the restructuring and diversification of design ideas. With the additional freedom in the design workspace, there are supplementary design considerations/limitations as well for additively manufactured forms and optimising these provide the best outcome for specific design needs.

KiHa 80 Series
The KiHa 80 series (キハ80系) was a diesel multiple unit type that operated on express services from 1960 to 2002, under Japan National Railways and later under JR Hokkaido and JR Central. Two variants were initially built: the KiHa 81 series (キハ81系) to replace the then steam-operated Hatsukari services in 1960, and the KiHa 82 series (キハ82系) for other services from 1961 to 1967; the KiHa 81 series sets would receive the fourth Blue Ribbon Award for outstanding design from the Japan Railfan Club (ja). The idea for the KiHa 81 series train was formulated at the first meeting of the Asian Railways Conference that occurred in Tokyo in late 1958. At that time, all services operating on non-electrified lines used steam locomotives, one of these services being the Hatsukari. By early 1960, the new cars were scheduled to start service in December of that year. After a promotional film of the KiHa 81 series was shot between September 15–23, 1960, and a demonstration was given to the participants of the 1960 Asian Railways Conference on October 14, the sets began operating Hatsukari services as planned on December 10. In the late 1980s, three resort trains were built based on the series: two KiHa 84 series (キハ84系) trains (the Furano Express and Tomamu Sahoro Express) and one remodeled KiHa 82 train (the Resort Liner). The Furano Express would be reliveried from June to October 1987 as part of a promotion with All Nippon Airways, and win the 30th Blue Ribbon Award in the same year; the Tomamu Sahoro Express set would participate in a Shikoku event showcasing the trains of all JR Group companies in 1989. By the time of its retirement in 2002, it had been superseded by various multiple units such as the KiHa 183, KiHa 181, and 485 series. Most cars were scrapped by 2009, but some were preserved, including a KiHa 81 lead car at the Kyoto Railway Museum, and a KiHa 82 lead car on the Hakkōda Maru [ja].

HTC Touch Diamond
The HTC Touch Diamond, also known as the HTC P3700 or its codename the HTC Diamond, is a Windows Mobile 6.1-powered Pocket PC designed and manufactured by HTC. It is the first device to feature TouchFLO 3D - a new version of the TouchFLO interface, unique to the Touch family. The HTC Touch Diamond was first available in Hong Kong in late May 2008. It was available across all major European carriers in June 2008, and later in the year in other parts of the world. The United States Touch Diamond was launched on September 14, 2008 on the Sprint network, and April 10, 2009 on the Verizon Wireless network. The European release date was slightly delayed by a last-minute ROM update. The carrier bound names for this phone include T-Mobile MDA Compact IV, O2 XDA Diamond and O2 XDA Ignito. It is the official successor of the HTC Touch. The successor to the Touch Diamond - the HTC Touch Diamond2 - was announced in February 2009 for Q2 2009 release outside the US and Q4 release estimated for North America.

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.

It was established in 1998, and replaced in 2012 by the NATO Science and Technology Organisation (STO). RTO promoted and conducted co-operative scientific research and exchange of technical information among 26 NATO nations and 38 NATO partners. The largest such collaborative body in the world, the RTO encompasses over 3000 scientists and engineers addressing the complete scope of defence technologies and operational domains. This effort is supported by an executive agency, the Research and Technology Agency (RTA), that facilitates the collaboration by organising a wide range of studies, workshops, symposia, and other forums in which researchers can meet and exchange knowledge.

Categories of Point Cloud Segmentation Methods
Laser point clouds have been widely used in many fields, such as autonomous driving, augmented reality and so on. Point cloud classification and segmentation are key to scene understanding. Therefore, many scholars have systematically studied point cloud classification and segmentation. Machine learning approaches are the most commonly used data analysis methods. In the field of point cloud data analysis, deep learning is used for point cloud classification and segmentation. To improve the accuracy of point cloud classification and segmentation, some researchers have drawn on image methods to handle point clouds.

Electromagnetic Coil
An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil (spiral or helix). Electromagnetic coils are used in electrical engineering, in applications where electric currents interact with magnetic fields, in devices such as electric motors, generators, inductors, electromagnets, transformers, and sensor coils. Either an electric current is passed through the wire of the coil to generate a magnetic field, or conversely, an external time-varying magnetic field through the interior of the coil generates an EMF (voltage) in the conductor. A current through any conductor creates a circular magnetic field around the conductor due to Ampere's law. The advantage of using the coil shape is that it increases the strength of the magnetic field produced by a given current. The magnetic fields generated by the separate turns of wire all pass through the center of the coil and add (superpose) to produce a strong field there. The more turns of wire, the stronger the field produced. Conversely, a changing external magnetic flux induces a voltage in a conductor such as a wire, due to Faraday's law of induction. The induced voltage can be increased by winding the wire into a coil because the field lines intersect the circuit multiple times. The direction of the magnetic field produced by a coil can be determined by the right hand grip rule. If the fingers of the right hand are wrapped around the magnetic core of a coil in the direction of conventional current through the wire, the thumb will point in the direction the magnetic field lines pass through the coil. The end of a magnetic core from which the field lines emerge is defined to be the North pole. There are many different types of coils used in electric and electronic equipment.

Respirator
A respirator is a device designed to protect the wearer from inhaling hazardous atmospheres, including particulate matter such as dusts and airborne microorganisms, as well as hazardous fumes, vapours and gases. There are two main categories: the air-purifying respirator in which respirable air is obtained by filtering a contaminated atmosphere, and the air-supplied respirator in which an alternate supply of breathable air is delivered. Within each category, different techniques are employed to reduce or eliminate noxious airborne contaminants. Air-purifying respirators range from relatively inexpensive single-use, disposable face masks sometimes referred to as a dust mask to more robust reusable models with replaceable cartridges often called a gas mask.
