IBM System/360 Model 195. The IBM System/360 Model 195 is a discontinued IBM computer introduced on August 20, 1969. The Model 195 was a reimplementation of the IBM System/360 Model 91 design using monolithic integrated circuits. It offers "an internal processing speed about twice as fast as the Model 85,  the next most powerful System/360". The Model 195 was discontinued on February 9, 1977, the same date as the System/370 Model 195.

About 20 Model 195 systems were produced.

Technical specifications
The basic CPU cycle time is 54 nanoseconds (ns). The system has a high degree of parallelism and can process up to seven operations at a time.
The system can be configured with 1, 2, or 4 MB of magnetic core memory (models 195J, 195K, and 195L) with a cycle time of 756 ns. A 32 KB cache, called a buffer memory in the IBM announcement, is standard. Memory blocks are brought into cache in units of 64 bytes.

The normal operating system for the Model 195 is OS/360 Multiprogramming with a Variable Number of Tasks (MVT).

Legacy
The Model 195 was later updated as the IBM System/370 Model 195 with the new System/370 instructions and the 370 time-of-day clock and control registers, but without the virtual memory hardware.

Atmosphere (Kolkata). Atmosphere is a luxury residential superstructure in Kolkata, India. Atmosphere consists of two tall towers and a 'Deya', the world's first residential floating sky sculpture.

Deya

Sitting 500 ft in the air, 'Deya' connects the two towers that make up Atmosphere. Deya houses club facilities for the residents of Atmosphere. Initially conceived as a cloud changing in porosity and form, Deya is not a physical extension of the tower as such, since the majority of the spaces within are open air. The skin is composed of expanded mesh panels wrapped around structural ribs. Special panels carrying shimmering mobile reflective disks are scattered across this mesh. The porosity of these materials enables Deya to appear different in form depending on how it is lit. The Deya will house the residents' community and recreational facilities, including a swimming pool, gymnasium, spas, running track, sporting facilities, virtual golf, cinema, meeting spaces and function facilities.

Radiative levitation. Radiative levitation is the name given to a phenomenon that causes the spectroscopically-derived abundance of heavy elements in the photospheres of hot stars to be very much higher than solar abundance or than the expected bulk abundance; for example, the spectrum of the star Feige 86 has gold and platinum abundances three to ten thousand times higher than solar norms.

The mechanism is that heavier elements have large photon absorption cross-sections when partially ionized (see opacity), so efficiently absorb photons from the radiation coming from the core of the star, and some of the energy of the photons gets converted to outward momentum, effectively 'kicking' the heavy atom towards the photosphere.  The effect is strong enough that very hot white dwarfs are significantly less bright in the EUV and X-ray bands than would be expected from a black-body model.

The countervailing process is gravitational settling, where, in very high gravitational fields, the effects of diffusion even in a hot atmosphere are cancelled out to the point that the heavier elements will sink unobservably to the bottom and lighter elements settle on the top.

Airbus Helicopters X6. The Airbus Helicopters X6 is a design concept for a 19-seat twin-engined heavy lift helicopter to replace the Airbus Helicopters H225. Development was stopped in early 2018.

Development
 
In June 2015, Airbus Helicopters announced the start of a two-year concept development phase including a customer advisory panel: it will be targeted at the commercial transport market, the oil and gas industry work and for search and rescue work, aiming for entry into service around 2022-23.

In June 2017, the European Commission approved €377 million ($420 million) of repayable state aid, due to be paid back over eight years : €330 million from France and €47.25 million from Germany.
It would be the first Airbus commercial helicopter controlled by fly-by-wire and should offer lower noise and a 15-20% reductions in fuel burn and direct operating costs compared to current aircraft. 
The Safran Aneto was proposed to power the 11 t class helicopter.

In January 2018, its development was suspended as it is lacking disruptive fly-by-wire and engine suppliers, and while the military and parapublic H225 market stayed strong in 2017 with 44 orders, the offshore oil and gas market shrank; the €377 million French and German refundable launch aid is not yet allocated but could be used if the X6 is launched.
The offshore oil and gas market continued to shrink with the North Sea oilfield, its primary market, continuing to be depleted and the oil price presently too low to finance new operations.

Load path analysis. Load path analysis is a technique of mechanical and structural engineering used to determine the path of maximum stress in a non-uniform load-bearing member in response to an applied load. Load path analysis can be used to minimize the material needed in the load-bearing member to support the design load.

Load path analysis may be performed using the concept of a load transfer index, U*. In a structure, the main portion of the load is transferred through the stiffest route. The U* index represents the internal stiffness of every point within the structure. Consequently, the line connecting the highest U* values is the main load path. In other words, the main load path is the ridge line of the U* distribution (contour)  This method of analysis has been verified in physical experimentation.

Load path calculation using U* index 
In a structure, the main portion of the load is transferred through the stiffest route. The U* index represents the internal stiffness of every point within the structure. Consequently, the line connecting the highest U* values is the main load path. In other words, the main load path is the ridge line of the U* distribution (contour).  The U* index theory has been validated through two different physical experiments.

Since the U* index predicts the load paths based on the structural stiffness, it is not affected by the stress concentration problems. The load transfer analysis using the U* index is a new design paradigm for vehicle structural design.  It has been applied in design analysis and optimization by automotive manufacturers like Honda and Nissan.

In the image to the right, a structural member with a central hole is placed under load bearing stress. Figure (a) shows the U* distribution and the resultant load paths while figure (b) is the von Mises Stress distribution. As can be seen from figure (b), higher stresses can be observed at the vicinity of the hole. However, it is unreasonable to conclude the main load passes that area with stress concentration because the hole (which has no material) is not important for carrying the load. The stress concentration caused by the structural singularities like a hole or a notch makes the load transfer analysis more difficult.

Body contact (electricity). A body contact or body fault is a conductive connection between body and active parts of electrical equipment resulting from a fault.

A body, short or ground fault is:

Perfect (direct) contact
If there is no fault resistance in the circuit
Imperfect (indirect) contact
If a fault resistance is present in the circuit (e.g. wet branch, arc)

This can be caused by installation errors or defects, such as cable breaks.

There is a risk of electric shock when touching the parts of the system under voltage by the body joint. As a countermeasure, so-called protective conductors and residual current circuit breakers are used in electrical engineering.
