Response limits

In this equation, the eigenvectors A are the target yields, and the eigenvectors, E t), are the optimal fields. The eigenvector associated with the largest eigenvalue is the globally optimal field, in the weak response limit.

A key consideration in the design of cold formed members for blast is premature buckling of the relatively thin webs. This response limits the ultimate resistance which can be obtained by reducing the load capacity due to a change in the cross section. A factor of 0.9 is recommended to be applied to the design resistance to... 

Finite element methods (FEM) are capable of incorporating complex variations in materia stresses in the time varying response. While these methods are widely available, they are quite complex and, in many cases, their use is not warranted due to uncertainties in blast load prediction. The dynamic material properties presented in this section can be used in FEM calculations however, the simplified response limits in the next section may not be suitable. Most FEM codes contain complex failure models which are better indicators of acceptable response. See Chapter 6, Dynamic Analysis Methods, for additional information. 

Maximum acceptable values for ductility and support rotation are presented in Appendix 5.B. Predicted response must be compared to ductility ratio and support rotation limits to ensure that neither is exceeded. The engineer must determine if lower limits are appropriate. The values vary with material type, section type and protection category required. For reinforced concrete members, response limits are influenced by the shear reinforcing provided as well as the type of response (i.e., flexure, shear, compression). In general, for elements in which shear or compression... 

Because low response limits (less than 2 degrees) will be used, dynamic design stresses will be equal to yield dynamic stresses. Refer to Table 5.A.4. 

All too frequently, researchers perform experiments beyond the means of the spectrometer used. The most common problem involves concentrations exceeding the linear response limits of the spectrometer. When this happens, solution of Eq. (2) becomes intractable. The most common mistake in infrared spectroscopy is when samples with absorbance greater than ca. 2-3 are measured with a DGTS detector [56]. At this point, the response of the spectrometer is no longer linear, and quantitative information is no longer accessible. The same type of situation exists in NMR, except it is perhaps a little more severe. The difficulties encountered when performing quantitative NMR work are well known [57, 58]. Most other types of spectrometers have similar limitations. 

Patients without prior use - The initial dose should be lower, with subsequent dosing adjusted based on individual response. Limiting the total dose injected into the sternocleidomastoid muscles to 100 units or less may decrease the occurrence of dysphagia. 

Dose adjustment - Dosages may be adjusted gradually to achieve an optimal response. Limited experience shows a significant increase in the incidence and severity of serious toxic reactions, especially bone marrow suppression, at doses greater than 20 mg/week in adults. Although there is experience with... 

The dynamics of the interfacial electron-transfer between Dye 2 and TiOz were examined precisely by laser-induced ultrafast transient absorption spectroscopy. Durrant et al.38) employed subpicosecond transient absorption spectroscopy to study the rate of electron injection following optical excitation of Dye 2 adsorbed onto the surface of nanocrystalline Ti02 films. Detailed analysis indicates that the injection is at least biphasic, with ca. 50% occurring in <150 fsec (instrument response limited) and 50% in 1.2 0.2 psec. 

Taxa. Although many species show the classic inverse relationship between stomatal frequency and C02, not all species do so. Therefore, the sensitivity of the species of fossil leaves needs to be tested when selecting fossil species to work with. Moreover, since plants have morphological and physiological constraints that do not allow adjustment of stomatal numbers to infinitely high or low C02, plant species have species-specific response limits to C02 (Kiirschner et al. 1997). For instance, the nonlinearity of the stomatal index-elevation... 

Factors may have associated values called levels of variations. Each state of a black box has a definite combination of factor levels. The more different states of the black box that exist, the more complex is the research subject. Formalization of preliminary information includes analysis of reference data, expert opinions and use of direct data, which enables correct selection of response, factors and null point or center of experiment. Factor limitations are also defined at this stage. If the research is linked with several following responses, then response limitations also have to be analyzed. The next phase refers to defining the research problem. When defining this problem one must keep in mind the research-subject model, and in a general case it is Eq. (2.1) that defines the link between the inlet and outlet of the black box. Defining the research problem is possible only now when its aim has been determined, the criteria established, the factors, limitations and null point defined. The problem is a simple one when only one response or optimization criterion is in... 

Genetically corrected autologous stem cells engraft, but host immune responses limit their utility in canine alpha-L-iduronidase deficiency. Blood 93, 1895-1905. 

Different microorganisms or parasites are used as inducers of the immune response of invertebrates. Constituents of the bacterial membrane may also be considered as successful inducers. Nevertheless, they may not develop the full immune response, limiting the possibility to recover all the armamentarium build by the invertebrate to fight off an infection (34). 

In this section we analyze the surface investigation of molecular crystals by the technique of UV spectroscopy, in the linear-response limit of Section I, which allows a selective and sharp definition of the surface excited states as 2D excitons confined in the first monolayer of intrinsic surfaces (surface and subsurfaces) of a molecular crystal of layered structure. The (001) face of the anthracene crystal is the typical sample investigated in this chapter.
