Defined design

Chaddock (1975) defined design as, the conversion of an ill-defined requirement into a satisfied customer. 

The term designer drug was prohahly first used in 1968 by Gary Henderson, a chemist at the University of California at Davis. Henderson defined designer drugs as "substances where the psychoactive properties of a drug are retained, but the molecular structure has been altered to avoid prosecution."... 

Note The term subchain may be used to define designated subsets of the constitutional units in a chain. 

There is only one simply stated, yet poorly defined, design criterion for this problem Propose some materials that have improved wear resistance for fabricating parts of high-pressure pumps and piping to be used in the pumping of coal slurries. 

To ensure the successful design of a reverse osmosis process, several factors should be considered. These considerations encompass the feed solution, the membrane module, and the use of other processes in the pre- and post-treatment processes. A thorough knowledge of the feed stream and its components is essential to the prevention of membrane damage and product impurities. Once the feed stream is characterized and the process objective is defined, design can be initiated. 

The degradation of a pollutant can be accelerated by increasing the useful area of the attached growth bioreactor. Flux rate is the mass per unit of area per unit of time. Thus, as area increases, the mass per unit of time increases. Time can influence choices indirectly. In a packed column, one of the defining design features is called the empty bed residence time (EBRT), defined as the volume of the vessel minus the volume taken up by the substratum plus the biofifin. 

Change in equipment to a different None defined design and different operating conditions... 

Engineering Application - The engineering application of the reactive chemicals data that defines design parameters or operating conditions necessary to prevent reactive chemicals accidents. 

Although well-defined design strategies exist for the optimal operation of a purely separative SMB [12], nothing comparable is available for the SMBR, although some similarities between the two units can be exploited in order to provide guidelines for the design of the latter system. 

While a designable structure implies a large neutral network, the specific topology of the network is not defined. Designability only measures the volume of sequence space that folds into a structure, whereas... 

Generally follow traditional, resource-defined designs... 

System vahdation is employed as a mechanism to estabhsh objective evidence that a system consistently performs according to its predetermined requirements, specifications, and quality attributes. The GAMP software categories provide some guidance as to activities that should be followed as a minimum to provide the objective evidence of the system meeting performance objectives. The complexity of the computerized system should determine the extent of this effort. There are many life-cycle models published that fadhtate the creation of this objective evidence. Acceptable life-cycle models will include phases for Define, Design, Develop, and Operate. 

Note When engineering firms are retained, the scope of their work must be limited to clearly defined design work. 

These define design criteria, applicable codes and preferences consistent with code requirements. They should reflect the minimum quality requirements while setting a limit to costly practices. 

Certain defined design and operational parameters will be intimately associated with the black box and these are shown on the diagrammatic representation of the overall process shown in Fig 1. The parameters can be considered of two types ... 

The manufacturer should define design conditions, normal operating ranges, operating ranges, and alert and action limits. 

The required design life will generally affect materials selection and/or Ihe determination of the recommended corrosion allowance. Normally, the user or process licensor will define design life requirements. It is helpful to define the design life requirements in the Notes addendum of the template. 

Step 1 Select those anthropometric measures that directly relate to defined design dimensions. Example hand length related to handle size. 

The overall RPD approach is based on the idea of an evolutionary design cycle (Bullinger et al. 1996). In contrast to traditional approaches with defined design phases and respective documents, such as specification lists or concept matrices, the different design phases are result oriented. 

As a platform manual defines platform capability and requirements, a design manueil defines design capability and requirements. Below is the description of a design manual. 

Boundary conditions should be established for each design parameter that define requirements to achieve design performance. These conditions define design limitations based on process and tech-... 

Open-architecture concept A general methodology for the development of functional modules that may be readily integrated to form a higher-level system through weU-defined design and interface constructs.
