Sumlnary--A method is described for finding the normal displacements of the surface of a semi-infinite solid, subjected to arbitrary, transient surface heating. Analytical expressions are derived for the displacements due to instantaneous and continuous point and line heat sources and these can be integrated to produce the solutions to particular problems. The method is illustrated by applicati...
Research on protection forests designed to alleviate rockfall hazard has increased enormously over the last decade. Data are available concerning the most suitable stem spacing and density regimes in stands. The species used in protection forests can also influence enormously the effectiveness of the forest in conferring a protective role. Little information exists, however, about either the me...
The effect of the relative affinity (Ka) on the antitumor efficacy of monoclonal antibodies (MAbs) has been questioned. It has previously been shown in experimental models that the use of MAbs with higher relative Kas manifests itself in a higher percentage of injected dose of MAb bound to tumor. On the other hand, mathematical models have proposed that the use of higher affinity MAbs may be di...
Laboratory and field demonstration results obtained as part of the DARPA-sponsored Coherent Communications, Imaging and Targeting (CCIT) program are reviewed. The CCIT concept uses a Phase Conjugation Engine based on a quadrature receiver array, a hologram processor and a spatial light modulator (SLM) for highspeed, digital beam control. Progress on the enabling MEMS SLM, being developed by a c...
Modern tracking technology for full body tracking, also referred to as motion capturing, can be used as an alternative or a complementary method to video recordings (see also Chapter 72. a on documenting with data gloves for a discussion). It offers a high precision of position and orientation information regarding specific points of reference, which can be chosen by the experimenter. Motion tr...
A modified Redlich-Kwong equation of state is proposed. Vapor pressures of pure compounds can be closely reproduced by assuming the parameter a in the original equation to be temperature-dependent. With the introduction of the acentric factor as a third parameter, a generalized correlation for the modified parameter can be derived. It applies to all nonpolar compounds. With the application of t...
An analysis of notifications of tuberculosis in the City of Birmingham during the three-year period 1960-62 related to the population data from the Census of 1961 showed important differences between the notification rates of groups defined by their place of birth, and also differences in the age distributions of notification rates between these groups (Springett, 1964). A survey of notificatio...
In this paper we obtain at least 61 new singly even (Type I) binary [72,36,12] self-dual codes as a quasi-cyclic codes with m=2 (tailbitting convolutional codes) and at least 13 new doubly even (Type II) binary [72,36,12] self-dual codes by replacing the first row in each circulant in a double circulant code by "all ones" and "all zeros" vectors respectively. Keywords—convolutional encoding, qu...
