Development minimization

In applications, increased capability in PEPT will enable more work with liquids and with multi-phase systems, and product-oriented studies aimed at probing the formation of microstructure. At the other extreme lies large-scale pilot- or process-level study which must be carried out in situ, using the new mobile PEPT camera. In large-scale applications, it will not in general be possible to provide trajectory information for the entire process volume. The challenge here is to develop "minimal" PEPT, in which location information is provided at as coarse a level as possible, consistent with the objectives of the study. [Pg.176]

The aim now is to develop minimal cut sets, which show just the minimal number of events and combination of events that are needed for the top event to take place. The following process is followed ... [Pg.621]

One exciting possibility is the development of therapeutic PROTAC molecules that would be active only in a particular tissue of interest. The identification of a ligand for an E3 ligase that is expressed in a tissue-specific manner would enable highly specific PROTAC-based therapeutics to be developed, minimizing potential off-target effects of the drug. [Pg.92]

While chemotherapy and radiotherapy can greatly help patients, they are limited because their mechanism of action may also affect normal proliferating cells in the body. In recent years, researchers have focused on developing minimally invasive and highly effective therapies utilizing gold nanoshells to address current limitations. [Pg.647]

Palliative treatment options for recurrent head and neck cancer are limited by the proximity of vital vascular and neural structures and the aggressive nature of most of these tumors. Laser-induced interstitial thermotherapy (LITT) is a recently developed minimally invasive treatment modality. It is a minimally invasive technique for local tumor destruction within solid organs. [Pg.215]

Chemical processes will in the future need to be designed as part of a sustainable industrial development which retains the capacity of ecosystems to support industrial activity and life. This book therefore places a high emphasis on waste minimization and energy efficiency in the context of good economic performance and good health and safety practices. [Pg.473]

There are, however, technological means available to burn incompletely desulfurized fuels at the same time minimizing SO2 emissions. In the auto-desulfurizing AUDE boiler developed by IFF, the effluent is treated in place by an absorbent based on lime and limestone calcium sulfate is obtained. This system enables a gas desulfurization of 80% it requires nevertheless a relatively large amount of solid material, on the order of 200 kg per ton of fuel. [Pg.256]

Based on a preliminary set of acceptance criteria s developed by LM Glasfiber a standard data-set has been developed for each of the above mentioned set-ups, in order to minimize the scanning time. During the performance demonstration at LM Glasfiber the effective scanning time for a complete 21m wind turbine rotor blade based on the preliminary acceptance criteria s, was found to be less than hour. [Pg.982]

A systematic comparison of two sets of data requires a numerical evaluation of their likeliness. TOF-SARS and SARIS produce one- and two-dhnensional data plots, respectively. Comparison of sunulated and experimental data is accomplished by calculating a one- or two-dimensional reliability (R) factor [33], respectively, based on the R-factors developed for FEED [34]. The R-factor between tire experimental and simulated data is minimized by means of a multiparameter simplex method [33]. [Pg.1812]

Although it was originally developed for locating transition states, the EF algoritlnn is also efficient for minimization and usually perfonns as well as or better than the standard quasi-Newton algorithm. In this case, a single shift parameter is used, and the method is essentially identical to the augmented Hessian method. [Pg.2352]

These methods, which probably deserve more attention than they have received to date, simultaneously optimize the positions of a number of points along the reaction path. The method of Elber and Karpins [91] was developed to find transition states. It fiimishes, however, an approximation to the reaction path. In this method, a number (typically 10-20) equidistant points are chosen along an approximate reaction path coimecting two stationary points a and b, and the average of their energies is minimized under the constraint that their spacing remains equal. This is obviously a numerical quadrature of the integral s f ( (.v)where... [Pg.2354]

In order to make END better suited to the application of low energy events it is important to include an explicitly correlated description of the electron dynamics. Therefore multiconfigurational [25] augmentations of the minimal END are under development. [Pg.234]

Techniques have been developed within the CASSCF method to characterize the critical points on the excited-state PES. Analytic first and second derivatives mean that minima and saddle points can be located using traditional energy optimization procedures. More importantly, intersections can also be located using constrained minimization [42,43]. Of particular interest for the mechanism of a reaction is the minimum energy path (MEP), defined as the line followed by a classical particle with zero kinetic energy [44-46]. Such paths can be calculated using intrinsic reaction coordinate (IRC) techniques... [Pg.253]

Let us stress immediately that minimal must not be understood in a pejorative sense Frequently it is more difficult to develop a simple model... [Pg.489]
