Symbolic language (engineering). In engineering, a symbolic language is a language that uses standard symbols, marks, and abbreviations to represent concepts such as entities, aspects, attributes, and relationships.

Engineering symbolic language may be used for the specification, design, implementation, management, operation, and execution of engineered systems.

Communication using precise, concise representations of concepts is critical in engineering. The Nuclear Principles in Engineering book begins with a quote on symbolic language from Erich Fromm and its power to express and depict associations.  The engineering employs symbolic language in a way that is not purely text-based and not purely image-based to represent and communicate knowledge.

Examples in chemical engineering include the symbolic languages developed for process flow diagrams and for  piping and instrumentation diagrams (P&IDs).

In electrical engineering, examples include the symbolic languages developed for network diagrams used in computing.

Ladder logic was originally a written symbolic language for the design and construction of programmable logic control (PLC) operations in mechanical and control engineering.

Recycled wool. Recycled wool, also known as rag wool or shoddy is any woollen textile or yarn made by shredding existing fabric and re-spinning the resulting fibres. Textile recycling is an important mechanism for reducing the need for raw wool in manufacturing.

Shoddy was invented by Benjamin Law of Batley in 1813. It was the dominant industry of Batley and neighbouring towns in the West Riding of Yorkshire, known as the Heavy Woollen District, throughout the 19th and early 20th centuries. Following its decline in the United Kingdom, the centre of the shoddy trade shifted to the city of Panipat in India. Efforts have been made to revive the British recycled wool industry in the 21st century.

Terminology 
Historically, recycled wool products were called rag wool. Manufacturers distinguished between three main categories of rag wool:

 Shoddy – made from loosely woven or "soft" textiles that could be pulled apart relatively easily;
 Mungo – made from "hard" fabrics such as felts, that were harder to disintegrate but resulted in a finer product;
 Extract – made from the wool portion of cotton/wool blended fabrics.

In practice, few outside the industry were aware of these distinctions, even when rag wool was widely used. The common name was shoddy, which became a generalised term for poor quality goods. It is still used as a technical term for recycled wool within the industry.

Regulators in the United States make a distinction between reprocessed wool, which is made from manufactured wool products that were never used by the consumer, and reused wool, which the consumer has used. Other bodies refer to these as pre-consumer and post-consumer waste material.

The terms virgin wool and new wool are used to distinguish newly-produced, never-used wool from shoddy.

GS&WR Class 37. The Great Southern and Western Railway (GS&WR) Class 37 consisted of six 4-4-2T tank engines. The first two built by locomotive superintendent Henry Ivatt (Snr.) were based on a previous 2-4-0T design by McDonnell, as were some 2-4-2Ts Ivatt produced two years earlier for the Kerry branches.

Construction
In 1900 Robert Coey, who by then had been promoted Inchicore Railway Works Manager to locomotive superintendent, produced four of a heavier and more powerful , these were known as Class 27.

Robert Coey in 1902 produced four more of the lighter class built by Ivatt, these were to be the final passenger tanks built by the GS&WR.

Design
The Class 37 had a very low  maximum axle load enabling a very high route availability.  By contrast the Class 27 had a higher  maximum axle load .

Service

On the amalgamation to Great Southern Railways in 1925 some of these classes were allocated to the former Dublin and South Eastern Railway (DSER) services to , where there was a shortage of motive power at least in part due to the ravages of the Irish Civil War.  By the 1930s most have been allocated to the Cork local services.

By 1948 the type was regarded as obsolete but all lasted until the 1950s with the last withdrawn in 1955.

Absorption heat transformer. An absorption heat transformer (AHT) is a device which transfers heat from an intermediate temperature level to a high temperature level by means of an absorption process. It is driven by the temperature difference between the intermediate temperature and a low temperature level. The absorption heat transformer splits a heat flow  at an intermediate temperature level  in two heat flows,  at a higher (revaluated) temperature level  and  at a lower temperature level  (rejection heat). Such a device is also denominated type II absorption heat pump or booster heat pump. Absorption heat transformers are especially suitable for heat recovery from industrial processes, its main advantage being the capacity to upgrade to a usable level the temperature of waste heat streams using only negligible quantities of electrical energy and no additional primary energy.

Definition of the thermal coefficient of performance

It revaluates approximately 50% of the driving heat flow. The temperature lift from the intermediate to the high temperature level is up to 50K. 
The simplest construction, a single effect absorption heat transformer, consists of one condenser, one evaporator, one absorber and one generator.
In contrast to a type I absorption heat pump an absorption heat transformer operates in reverse. 
The difference with absorption heat pump is that the absorber and evaporator now operate at high pressure and the condenser and generator at low pressure. The most common working pairs are water/lithium bromide (refrigerant = water, absorbent = LiBr) and ammonia/water (refrigerant = ammonia, absorbent = water).

Process
A single absorption heat transformer consists of an absorber, generator, evaporator and condenser. In addition, there are a refrigerant pump, solution pump, solution throttle and solution heat exchanger for internal heat recovery. At the evaporator the refrigerant evaporates by the heat input at intermediate temperature level. The refrigerant vapour is absorbed in the absorber. Due to the released heat of absorption the process delivers heat at the high temperature level. This heat is the revalued heat. Consequently, the absorbent is diluted while absorbing the refrigerant vapour. That diluted absorbent streams through the throttle to the generator. In the generator the refrigerant desorbs from the diluted solution. This process is driven by the heat input at the intermediate temperature level. The refrigerant vapour is condensed in the condenser and it is pumped by the refrigerant pump into the evaporator. The heat at the condenser occurs at low temperature level. The concentrated absorbent is pumped into the absorber by the solution pump.

Union Bros. Furniture Company. The Union Bros. Furniture Company, also known as the Plymouth Wallpaper Building, is a historic building located in Baltimore, Maryland, United States. It is composed of three sections that were built at three different times between 1923 and 1955. Each section reflects a distinct architectural style and construction techniques from the city's industrial architectural history. The oldest section, completed in 1923, is a utilitarian design that consists of simple brick walls and timber framing with punched openings for the windows. The second section utilized poured-in-place concrete construction techniques. The third section, completed in 1955, is a single-story mid-century modern structure that consists of brick load bearing walls that are spanned by steel beams. It features more elaborate brick detailing than the other two sections and it features a streamlined aluminum entrance canopy.

The building is also significant for its association with Baltimore's furniture industry, and brothers Philip and Rubin Union and their partner Benjamin Ruttenberg who owned the building. The Union Brothers Furniture Company was in operation from 1919 to 1972. An application made to list this building on the National Register of Historic Places was resubmitted in 2018.

Structural reliability. Structural reliability is about applying reliability engineering theories to buildings and, more generally, structural analysis. Reliability is also used as a probabilistic measure of structural safety. The reliability of a structure is defined as the probability of complement of failure . The failure occurs when the total applied load is larger than the total resistance of the structure. Structural reliability has become known as a design philosophy in the twenty-first century, and it might replace traditional deterministic ways of design and maintenance.

Theory 
In structural reliability studies, both loads and resistances are modeled as probabilistic variables. Using this approach the probability of failure of a structure is calculated. When loads and resistances are explicit and have their own independent function, the probability of failure could be formulated as follows.

where  is the probability of failure,  is the cumulative distribution function of resistance (R), and  is the probability density of load (S).

However, in most cases, the distribution of loads and resistances are not independent and the probability of failure is defined via the following more general formula.

where 𝑋 is the vector of the basic variables, and G(X) that is called is the limit state function could be a line, surface or volume that the integral is taken on its surface.

Solution approaches

Analytical solutions 
In some cases when load and resistance are explicitly expressed (such as equation () above), and their distributions are normal, the integral of equation () has a closed-form solution as follows.

Simulation 

In most cases load and resistance are not normally distributed. Therefore, solving the integrals of equations () and () analytically is impossible. Using Monte Carlo simulation is an approach that could be used in such cases.
