Under Engineering

Analyze the actual methods presented. Find the core methodologies, the mathematical models, and the underlying engineering and/or other science foundation. 

Focuses attention on underlying engineering and scientific principles, which are also the basis of the unifying elements to all processes. 

The results of the exhaust stack measurements of gaseous emissions indicate that the use of EDS/DF-2 fuel blends under engine load conditions resulted in a moderate increase in CO emissions (25%) and a moderate decrease in THC emissions (26-31%) when compared to baseline (0%) tests. The EDS/DF-2 fuel blends all showed substantial increases in both CO and THC emissions at the no-load condition. 

Another expense which is included under indirect plant cost is the item of construction or field expense and includes temporary construction and operation, construction tools and rentals, home office personnel located at the construction site, construction payroll, travel and living, taxes and insurance, and other construction overhead. This expense item is occasionally included under equipment installation, or more often under engineering, supervision, and construction. If construction or field expenses are to be estimated separately, then Table 15 will be useful in establishing the variation in percent of fixed-capital investment for this indirect cost. For ordinary chemical-process... 

Commercial plants Sixty-three Spheripol process plants with a total capacity of more than 11 million tpy are in operation worldwide. An additional 13 plants are under engineering design or construction. Total licensed capacity exceeds 13.5 MMtpy. Single-line ranges from 40,000 to 400,000 tpy. 

Equation (7.16) is applied over a short period of time. In it, dQ is comprised of the sum of the chemical heat release during this time, obtained from equation (7.13) which, in turn, depends upon equations (7.8), and the heat lost to the surrounding boundaries. Under engine conditions the last is evaluated from appropriate heat transfer data [76,151-154]. Finite difference forms of the equations, for small time increments, yield values of incremental temperature change in equation (7.16). The last term in this equation depends upon the temperature and pressure changes in the end gas and these depend upon the piston and flame motions. They may be obtained from either engine measurements or an engine model, as discussed in Sections 7.5.4 and 7.5.5, respectively. 

There is also the possibility that inhomogeneity can arise from molecular fluctuations within an otherwise homogeneous medium. However, results of the quantitative studies of van Tiggelen [169] and Borisov [170] suggest this effect would be relatively weak under engine conditions.

NOV-94 JACADS (Unusual Occurrence) ECR Detonation of rocket on fuze shear caused agent migration to observation corridor. All agent vapor contained under engineering controls and exhausted through the MDB charcoal filter units. 

Operators had shut down the LIC 2 and adjusted the atomizing air pressure to stabilize flame strength. Ventilation upset allowed vapor to migrate to the Observation Corridor. Agent maintained under engineering controls. 

Inadvertently shut down of ventilation system. All agent vapor maintained under engineering controls. LIC secondary room was maintained under engineering controls. No agent release. 

Apr-94 JACADS (Unusual Occurrence) LIC/MPF airlock MDB filter unit taken off-line to perform maintenance. Air dampers on spare filter did not operate properly causing a fluctuation in the MDB. Agent maintained under engineering controls. Agent alarm in LIC/MPF airlock. Cause limit switch failure. Corrective actions taken. 

The heat resistance of polyvinyl chloride was also improved by post chlorination, the ductility of polyethylene was Improved by increasing the molecular weight and the usefulness of polystyrene was Increased by copolymerization with acrylonitrile. Nevertheless, in spite of improvement in performance, resulting from these modifications, most general purpose plastics were under engineered for many applications. 

The fresh catalysts (stabihzed in reaction at 550 C) were aged under laboratory conditions and under engine bench conditions (Table 2). 

Commercial plants Nine ammonia plants have been commissioned between 1998 and 2010, and six facilities are under engineering or construction with capacities ranging from 600 metric tpd up to 2,200 metric tpd, resp. 3,300 metric tpd for the Dual Pressure Ammonia Process. 

Drugs as weapons and drones are just two of the very many types of weapons which are currently under engineering development, with potential for hugely deleterious effects on human wellbeing. Further analysis of the contribution of engineering to war and peace can begin by consideration of just war theory. 

The main activities under engineering development are setting up of Large Components Test Rig (LCTE.), component hydraulics, sodium pump and instrumentation, amongst others. 

The harshest conditions of all are experienced in the engine compartment. In the average car however the total running time is typically only 5000 hours. The trends of low bonnets, reduced air flow and under-engine protection all increase the ambient temperature. The highest temperatures occur when the vehicle is standing after high-load use. 

Polyether ether ketone (PEEK) is a linear, aromatic, semi-crystalline thermoplastic possessing excellent thermal stability, chemical resistance and mechanical properties under engineering applications. It has the repeating unit structure, 0—Ph—O—Ph—CO Ph—, wherein "Ph" is the 1,4-phenylene unit. Its true scientific name is poly (oxy-1, 4-phenylene-oxy-l, 4-phenylenecarbonyl-l, 4-phenylene). The polymer is featured in a wide range of applications including transportation, energy, industrial, electronics, semiconductor and medical.
