Executability, of specifications

Layer 2 provides the external representation of all engaged tools. Until now, there is no possibility to describe all details of the participating tools (e.g., the sequences of the commands enacted inside tools are not represented). Tools are just seen as black boxes that support the execution of specific process steps. 

Simultaneous execution of specific tasks by all members of the emergency stroke team permits efficient progression to diagnosis and treatment. There should be a plan of action and all members of the team should be familiar with it. Table 10.2 delineates the tasks of each member of a hypothetical acute stroke team. 

Some passive controls will live outside the user interface and may not be apparent to day-to-day operators. For example, HIT systems typically need to exhibit resiliency in their architecture whether brought about through redundancy or other systematic means. These design features represent active engineered controls. However it is common for this to be supported by other more passive controls which require some degree of human intervention. The platforms on which systems reside can often be monitored for availability and performance. In some cases systems may be specifically instrumented to provide metrics on the execution of specific functions or the success of database transactions. Similarly systems may log errors or failed messages which are then made available for inspection by service management personnel. 

Tactical—ICS elements characterized by the execution of specific actions or plans in response to an actual incident. 

The term geoengineering comes from the Greek word geo, meaning earth, and the word engineering, a field of applied science that incorporates and uses data from scientific, technical, and mathematical sources in the invention and execution of specific structures, apparatuses, and systems. 

Robotics Science of designing machines that can replace human beings in the execution of specific tasks, such as physical activities and decision making. 

In this book, I have tried to assimilate the subject matter of various papers (and sometimes diverse views) into a comprehensive, unified treatment of gas turbines. Many illustrations, curves, and tables are employed to broaden the understanding of the descriptive text. Mathematical treatments are deliberately held to a minimum so that the reader can identify and resolve any problems before he is ready to execute a specific design. In addition, the references direct the reader to sources of information that will help him to investigate and solve his specific problems. It is hoped that this book will... 

The deficiencies revealed during the audit indicated that some of the medical surveillance programs were not site specific. The SSHAP should he written to ensure that workers are tested for not only general physical health, hut also for those substances that they might he exposed to during work activities. Besides the lack of specificity, it appears that execution of... 

At the other temperature extreme we have the measurements of specific heats executed at the temperatures of liquefied gases. A known mass of the substance is dropped into liquid carbon dioxide (— 78°), oxygen (— 183°), or hydrogen (— 250°), and the volume of gas liberated is measured. 

The validation process is subject to the following design specifications, user and performance requirements, preparation of a master plan/validation protocol (installation qualification, operational qualification, and performance qualification), execution of the protocol, preparation of a summary report, and on-going validation (and revalidation if changes are made). 

If an atom is situated on a center of symmetry, on a rotation axis or on a reflection plane, then it occupies a special position. On execution of the corresponding symmetry operation, the atom is mapped onto itself. Any other site is a general position. A special position is connected with a specific site symmetry which is higher than 1. The site symmetry at a general position is always 1. 

If an operation is invoked in a situation when the precondition is false or if, during the execution of the operation, its rely condition becomes false, then the specification does not state what the outcome should be. 

Internal quality control is undertaken by the inclusion of particular reference materials, called control materials , into the analytical sequence and by duplicate analysis. The control materials should, wherever possible, be representative of the test materials under consideration in respect of matrix composition, the state of physical preparation and the concentration range of the analyte. As the control materials are treated in exactly the same way as the test materials, they are regarded as surrogates that can be used to characterise the performance of the analytical system, both at a specific time and over longer intervals. Internal quality control is a final check of the correct execution of all of the procedures (including calibration) that are prescribed in the analytical protocol and all of the other quality assurance measures that underlie good analytical practice. IQC is therefore necessarily retrospective. It is also required to be as far as possible independent of the analytical protocol, especially the calibration, that it is designed to test. 

The unit of a wrapper with its associated program or database query is called an analyzer. Analyzers are often highly specific. The correctness of their results depends partially on certain conditions, such as the taxonomic specification. Annotation added by an analyzer is often in turn exploited by other analyzers executed later. EDITtoTrEMBL uses the conditions, which are stored in the RuleBase, for the execution of analyzers. Dispatchers, programs that coordinate the flow of entries between different analyzers, evaluate these conditions. 

In large measure, the problem associated with the execution of a stereoselective aldol condensation has been reduced to the generation of a specific enolate geometry. The recent results of Kuwajima (66a), which demonstrate that enolsilanes may be transformed into boryl enolates without apparent loss of stereochemistry (eq. [53]), should enhance the utility of vinyloxyboranes in stereoselective synthesis. The only current drawback to this procedure is associated with the presence of trimethylsilyl triflate (69), which must be removed from the reaction medium before the aldol condensation. It has recently been established that 69 is an effective catalyst for the aldol process (4). 

Sample preparation (SP) is generally not given adequate attention in discussions of pharmaceutical analysis even though its proper execution is of paramount importance in achieving fast and accurate quantification (see Chapter 5). Non-robust SP procedures, poor techniques, or incomplete extraction are the major causes of out-of-trend and out-of-specification results. The common SP techniques have been reviewed with a strong focus on tablets or capsules, as they are the primary products of the pharmaceutical industry. Detailed descriptions of SP methods for assays and impurity testing are provided with selected case studies of single- and multi-component products. 

This situation does not apply only to Germany. The Health and Safety Executive quotes specific figures for the UK, which give an idea of application of occupational health and safety legislation there In approximately 1.3 nullion British compaiues chemicals are handled. When questioned, only 16% of these compaiues were able to state the applicable law for handling chenucals or the limit values for these substances at the workplace. With regard to the need for protective measures, these 16% also rely almost entirely on the details contained in the safety data sheets. 

This section provides general comments that are pertinent to the design of process plant piping. It is intended to provide a convenient summary of commonly used information from various sources. It is not intended to serve as a comprehensive source of requirements or as a substitute for referenced codes, standards, and specifications. It is intended that qualified designers obtain copies of all applicable codes, standards, and specifications and thoroughly review all pertinent requirements of these documents prior to execution of work.
