Visuo-haptic mixed reality. Visuo-haptic mixed reality (VHMR) is a branch of mixed reality that has the ability of merging visual and tactile perceptions of both virtual and real objects with a collocated approach.  The first known system to overlay augmented haptic perceptions on direct views of the real world is the Virtual Fixtures system developed in 1992 at the US Air Force Research Laboratories.  Like any emerging technology, the development of the VHMR systems is accompanied by challenges that, in this case, deal with the efforts to enhance the multi-modal human perception with the user-computer interface and interaction devices at the moment available.
Visuo-haptic mixed reality (VHMR) consists of adding to a real scene the ability to see and touch virtual objects. It requires the use of see-through display technology for visually mixing real and virtual objects and haptic devices necessary to provide haptic stimuli to the user while interacting with the virtual objects.
A VHMR setup allows the user to perceive visual and kinesthetic stimuli in a co-located manner, i.e., the user can see and touch virtual objects at the same spatial location. This setup overcomes the limits of the traditional one, i.e, display and haptic device, because the visuo-haptic co-location of the user's hand and a virtual tool improve the sensory integration of multimodal cues and makes the interaction more natural. But it also comes with technological challenges in order to improve the naturalness of the perceptual experience.

ICP srl. ICP srl is an Italian wiring harness, automotive brake wear indicator and aircraft manufacturer founded by Tancredi (Edi) Razzano in 1980 and originally based in Piovà Massaia. The company relocated to Castelnuovo Don Bosco in Piedmont on 10 September 2009. ICP specializes in the design and manufacture of kit aircraft for amateur construction.

History
ICP was founded in 1980 to produce wiring harnesses for the automotive, electromechanical and domestic appliance markets. In 1984 the company expanded into designing and producing wear indicators for disc and drum brakes for cars,  industrial vehicles and motorcycles. The company provides wear indicators that are used by Alfa Romeo, Audi, Citroen, Chevrolet Corvette, Daf, Ferrari, Fiat, Iveco, Lamborghini, Lancia, Maserati, Peugeot, Renault and Volvo.

In the late 1990s Razzano decided to use the considerable investment he had made in CNC machining to produce kit aircraft, beginning with the ICP Bingo and Savannah aircraft. The use of the CNC machines allowed kits to be produced at low cost, making the company very competitive in the kit aircraft market. 

On 15 January 2012, ICP announced a collaborative production effort with Zenair of Canada to produce the Zenair CH650 at their plant, under the designation CH650Ei.
Even so, Zenith STOL CH 701 designer Chris Heintz considers the Savannah an unauthorized copy of his design.

ICP is currently developing an aviation engine, designated the ICP M09. The engine was designed by Franco Lambertini, previously with Moto Morini motorcycles. The M09 has no parts in common with other Lambertini motorcycle engines, but is a clean-sheet design for aviation use. The engine is a four stroke, two cylinder, four valve,  powerplant that delivers  at 7000 rpm and is capable of inverted flight. The first flight on an ICP Savannah S was on 18 December 2014.

NTH Ring. The NTH Ring (, first known as , also known as , ,  or ) is a ring worn only by graduates of the Master of Science in engineering or architecture programmes (formerly the sivilingeniør or  programmes), at the Norwegian University of Science and Technology (NTNU), formerly known as NTH (Norwegian Institute of Technology).

About 1,000 rings are sold per year.

Symbolism 
The ring was designed by architectural student Tormod Kristoffer Hustad, who won an international design competition for a symbol to represent the university in 1914. The gold ball symbolises the globe, and the steel ring and posts represent the technology and scientific advances that "hold the Earth up".

Design and sale 
The two components of the ring are made of 14 carat 585 yellow gold and surgical steel (originally an iron alloy). As the metals have different melting points, they cannot be soldered or welded together, so they are held together by the inner golden ring. Each ring is also individually numbered.

The ring is sold by two goldsmiths in Trondheim, Gullsmed Dahlsveen and Gullsmed Møller. Gullsmed Dahlsveen had exclusive rights to production for over 50 years, and has been producing the ring since 1928.

Significance 
Lise Lyngsnes Randeberg, a graduate of NTH, has said that the ring is a symbol of completion of a long and difficult course of education, and is particularly important for female engineers to show they have the capability to contribute professionally in a male-dominated environment.

Zirconium perchlorate. Zirconium perchlorate is an inorganic compound with the formula Zr(ClO4)4. It is a hygroscopic colorless solid that sublimes in a vacuum at 70 °C.  These properties show that the compound is covalently bonded molecule, rather than a salt.  It is an example of a transition metal perchlorate complex.

Synthesis and properties
It can be formed by treating zirconium tetrachloride with dichlorine hexoxide-perchloric acid mixture at −35 °C.

Zirconium perchlorate reacts irreversibly with most organic compounds but is inert towards carbon tetrachloride, chloroformide. With benzene at -10°C, crystals of Zr(ClO4)4•C6H6 are deposited.

Solid zirconium perchlorate undergoes a phase transition around 45 °C before melting between 95.5 and 96.0 °C.  Thermolysis near 120 °C gives zirconyl perchlorate.  Further heating around 290°C gives form zirconia and chlorine oxides.

Structure
In the gas phase the Zr(ClO4)4 molecule has a D4 symmetry with eightfold square antiprism oxygen coordination. Each perchorate group is bidentate. The chlorine atoms are in a tetrahedral arrangement around the central zirconium.

In the solid phase, Zr(ClO4)4 crystals are monoclinic with a=12.899, b=13.188, c=7.937 Å, β=107.91°. There are four molecules per unit cell.

Related substances
Titanium perchlorate and hafnium perchlorate are both known.

Salts of perchloratozirconates and hexaperchloratozirconates have been claimed including the caesium perchloratozirconates CsZr(ClO4)5, Cs2Zr(ClO4)6, and Cs4Zr(ClO4)8.

Zirconyl perchlorates have been claimed in older literature.

Hexaperchloratoaluminate. The hexaperchloratoaluminate ion is a polyatomic anion with the chemical formula . It is composed of six perchlorate () anions bound to a central aluminium ion (), resulting in a net charge of –3. This ion is a highly oxidizing and reactive complex, similar to other hexacoordinate aluminium complexes such as hexanitratoaluminate.

The aluminium perchlorate salts formed with hexaperchloratoaluminate are of particular interest due to their potential uses as energetic materials. The series of hexaperchloratoaluminate salts includes lithium hexaperchloratoaluminate, ammonium hexaperchloratoaluminate, tetramethylammonium hexaperchloratoaluminate, and trinitronium hexaperchloratoaluminate. Each of these compounds possess unique properties and may have potential applications in areas such as rocket propellants, pyrotechnics, and other explosive-based technologies.

Preparation
Hexaperchloratoaluminates can be synthesized by combining aluminum trichloride and various perchlorates in liquid sulfur dioxide at a temperature of –10°C:

,

,

.
To form hexaperchloratoaluminates, one can heat aluminium nitrate in the presence of nitrosonium or nitronium perchlorate at a temperature of 125 °C:

10–14 [NO]ClO4 + Al(NO3)3 → [NO2]3[Al(ClO4)6] + (gaseous products),

6–10 [NO2]ClO4 + Al(NO3)3 → [NO2]3[Al(ClO4)6] + (gaseous products),

.

Obtaining hydrazinium hexaperchloratoaluminate in a highly pure form is problematic. According to the available studies, this compound can only be produced via a low-yielding synthesis route including the reaction of aluminium chloride, hydrazinium perchlorate, and nitronium perchlorate: 

.

Guanidinium hexaperchloratoaluminate can be synthesized via the following reaction:

Bolesławiec rail viaduct. The Bolesławiec rail viaduct is a railway bridge over the river Bóbr in Bolesławiec in Lower Silesia, Poland.

Entirely made of stone, it is one of the longest bridges of its type in Poland and in Europe.

Statistics 
 Length: 490 m
 Height: 26 m
 Width: 8 m
 Number of spans: 35
 Main spans: 15 m, 11.5 m and 5.65 m
 Construction material: sandstone
 Construction period: 2 years
 Construction completion: 1846

History 
Rail transport came to Bolesławiec (then known as Bunzlau and part of Prussian Silesia) in 1845. Work was already being carried out on the extension of a rail line towards Węgliniec. Part of this work was a crossing of the river Bóbr. The Prussian architect Frederick Engelhardt Gansel was chosen for the project. Work began on June 18, 1844. Building work directly employed more than 600 people with another 3200 indirectly related to its construction. The construction took two years and was completed in July 1846.

Near the end of the war in 1945, retreating Germans blew up the central span crossing. After the war, reconstruction was fast and the bridge was returned to service in 1947.

In 2006, the viaduct was illuminated at the cost of nearly 180 thousand złoty. It is illuminated with 58 compact projectors which are mounted on the inner sides of the pillars of the bridge.

In October 2009, renovation work on the viaduct was completed. It had been sandblasted, its design completely renovated and maintained. In addition, the viaduct gained a new traction network, track layout, and rail extensions from both sides. Due to these upgrades, trains were able to travel up to 160 km/h.

Sa'ar 2-class missile boat. The Sa'ar 2 class ("Shalechet") is a class of missile boats built in Cherbourg, France at the Constructions Mécaniques de Normandie shipyard based on Israeli Navy modification of the German Navy's . Three of the ships class were converted from s in 1974.

Design and development 
The Israeli naval command had reached the conclusion by the early 1960s that their old Second World War-era destroyers, frigates and corvettes were obsolete and new ships and vessels were needed. Yitzhak Shoshan, later to command the destroyer INS Eilat at the time of her sinking, surveyed the available torpedo boat designs and recommended the German Jaguar class. The Israeli Navy asked Lürssen, the shipyard which built the Jaguar class, to modify the wooden design by switching to steel construction, adding  to the length, and revising the internal compartmentalization.  Due to Arab League pressure on the German government, this plan was not continued and a new builder was sought. The Israeli Navy discovered that the Cherbourg-based Constructions Mécaniques de Normandie shipyard owned by Félix Amiot had experience building patrol boats in cooperation with Lürssen and would build the boats, based upon the German designs and plans. The engines were imported from Germany. The project received the codename "Falling Leaves" ().

An initial group of six boats was ordered in 1965, with an armament of Bofors 40 mm guns and torpedo tubes and provision for fitting sonar. This group was designated the Sa'ar 1 class. When refitted with Gabriel anti-ship missiles, they became the Sa'ar 2 class. A second group of six boats, the Sa'ar 3 class, was ordered in 1968, with an OTO Melara 76 mm gun instead of the Bofors guns of the Sa'ar 1 class and with anti-submarine provisions omitted.

Description 
The boats were long, slender vessels. They measured  in length, with a beam of  and a draft of . Displacement is  standard and  full load. The boats were powered by four MTU 16V 538 diesel engines giving a total power of  and driving four propeller shafts. This gave a maximum speed of . Range was  at  or  at .

The vessels in the class come in two versions of armament. One version is equipped with five to eight Gabriel II surface-to-surface missiles (SSM), one Bofors L/70 40 mm gun, two  caliber M1919A4 Browning machine guns and four 7.62 mm FN MAG 58 general-purpose machine guns.

The other version is equipped with four RGM-84 Harpoon SSMs and two Gabriel II SSMs.
