Convolution algebras on locally compact spaces by William W Fairchild( Book )

1 edition published in 1967 in English and held by 4 WorldCat member libraries worldwide

The work continues the investigations which concern themselves with generalizations of the classical notion of convolution on topological groups. That such generalizations are warranted is clear from various examples, for instance those arising from differential equations, central functions, groups and semi-groups of operators, Delsarte translation operators, and hypercomplex systems
Multinucleon capture of k( - ) mesons and some associated problems of the k( - ) capture process by George Thomas Condo( Book )

2 editions published in 1962 in English and held by 3 WorldCat member libraries worldwide

The multinucleon absorption of K( - ) mesons is studied by searching for fast! hyperons emitted from K( - ) capture stars in normal and in water-soaked Ilford G5 nuclear emulsion. These fast (> 60 mev) hyperons are the only certain indication that a K( - ) meson was absorbed nonmesonically. On the basis of these data and their reasonable similarity with that of Evans et al., it is concluded that the capture of K( - ) mesons by the light emulsion nuclei (C, N, O) is 2.2! .3 times more likely to yield a fast hyperon that is K( - ) capture by Ag and Br. Combining this with the hyperon absorption probabilities deduced from a study of Auger electron emission, the multinucleon K( - ) absorption probability is approximately the same for light and heavy capturing nuclei in nuclear emulsion (excluding hydrogen). Of 56 fast hyperon events, 17 were consistent with K( - ) capture by a light nucleus. By combining these events with those reported by Evans et al., we find when a K( - ) meson is absorbed through a multinucleon channel by C12 and O16, that the basic interaction in 92% of the events is consistent with the destruction of a single particle subunit. The Auger spectrum resulting from capture and subsequent cascade of K( - ) mesons shows evidence for the line structure predicted by conventional theory. (Author)

The work of the program developed around two themes: (1) Ionic Mobility in the Alkali Halides, and (2) Color Centers in the Alkali Halides. The most significant results obtained on ionic mobility were the evidence for a contribution of vacancy pairs to the self-diffusion coefficient of the chloride ion in sodium chloride and the evidence for a high-temperature, high-frequency dielectric loss due to vacancy pairs in the alkali halides. Although much detailed information was obtained concerning the interaction and relationships of H, V, F, and a color centers in the alkali halides, the most important contributions were (1) the evidence that the H optical absorption band formed by x-rays at low temperatures is composed of overlapping bands due to H and V sub K centers and the determination of the position and shape of the band due to H centers, and (2) the evidence that interstitial particles (H centers or interstitial halogen atoms) can be formed by low energy, ultraviolet photons in crystals containing the hydroxyl ion as an impurity.

Extension and Public Service in the University of Illinois. Phase IReport by Urbana Illinois Univ.( Book )

2 editions published between 1967 and 1968 in English and held by 2 WorldCat member libraries worldwide

Phase ii of the report on the problem outlined in Phase I deals with specific recommendations for expanding and improving the extension and public service functions of the University of Illinois. To be effective, the university needs a master plan in which the four essential ingredients must be (1) broad, strong and explicit policy commitments by the top administration and the faculties, (2) the organizational machinery to carry it out, including close cooperation with the faculty. In a multi-university, each campus should be given responsibility for organizing, staffing and operating a comprehensive public service program. A vice president for public service should be responsible for university-wide coordination and joint or inter-campus programming. He should have approval powers regarding budgets and personnel, starter funds for program planning and execution, and should be primarily responsible for relations with private foundations and the federal government in public service matters. Each campus should have a public service officer, who would sit on the Public Service Board with the Vice President for Public Service. (3) In addition, policy and program improvements are essential, especially with regard to harnessing the services of the cooperative extension service for urban needs. The university should also give increased attention to off campus graduate programs and continuing education in the professions. (4) Continuous administrative refinement should be made in the light of evaluated experience. (Am)
The effect of heating on the room temperature strength of pristine e-glass rods by N. M Cameron( Book )

1 edition published in 1963 in English and held by 2 WorldCat member libraries worldwide

The influence of temperature on the room temperature strength of E-glass rods was studied. Groups of rods were heated in air at various temperatures in the range from 160 to 1100 F. The strength versus temperature relation was found to be qualitatively similar to that determined for E-glass fibres. Light and Electron Micrographs were made of the rod surface after various treatments. It is suggested that the most likely reason for the strength decrease, observed after heating, is an ordering or devitrification at the rod surface. (Author)

The dynamic response of shallow-buried arches subjected to blast loading( Book )

2 editions published in 1961 in English and held by 2 WorldCat member libraries worldwide

A study was made of the effectiveness of the surrounding soil in restraining the lateral movement of shallow-buried arches subjected to blast overpres ures from a nuclear explosion. The theory is developed for parabolic arches with circular or barrel arches included as a special case. It can be pplied equally well to arches oriented with their longitudinal axes perpendicular to or parallel to the direction of travel of the blast wave. The arch is considered to be buried near the surface of a semi-infinite soil mass. The depth of cover over the crown is limited to one-half of the arch span. The twohinged rather than the fixed arch is selected as representing more closely the shallow-buried rch structures used in full-scale nuclear tests to date. While these structures were not actually pinned at the arch abutments, their behavior under blast loading appears to resemble more closely the pinned th n the fixed case. he principal variables studied in the numerical examples include: (1) depth of cover, (2) overpressure loading, (3) arch material, and (4) arch span.

Factors Influencing the Lime Reactivity of Tropically and Subtropically Weathered Soils( Book )

1 edition published in 1971 in English and held by 2 WorldCat member libraries worldwide

Research to determine factors that significantly influence lime-pozzolanic reactions in soils has been fairly well restricted to soils of temperate regions. Extrapolation of this data to tropical soils was not justified without additional investigation. Phase I of the study, a literature survey, identified typical tropical soil characteristics, and summarized factors known to influence lime-pozzolanic reactions. Selection and sampling of soils for the sample suite, Phase II, was so accomplished to provide representative cross-sections of soil characteristics. Phase III, laboratory investigations, included determination of physical, chemical, and mineralogical properties of the 26 soils by standard techniques. Development of lime-pozzolanic reactions was measured by maximum increases in the unconfined compressive strength of the lime-treated soils after various curing periods. Due to restrictions on quantities of soil available for testing, some experimental similitude was required. In Phase IV, analysis and discussion, it was determined that organic carbon, soil pH, CEC, base saturation, Silica Sesquioxide and Silica-Alumina Ratios, pedologic order, and air-drying influence development of lime-pozzolanic reactions in Ultisols and Oxisols.

Crack Propagation in low-cycle fatigue of mild steel by S. T Rolfe( Book )

2 editions published between 1962 and 1963 in English and held by 2 WorldCat member libraries worldwide

An investigation was made of crack propagation in low-cycle fatigue of mild-steel plate specimens and has indicated that during crack propagation the type of loading cycle will affect markedly the fatigue behavior. Several types of reversed loading cycles have been included in the investi gation, namely constant load, reduced loads and constant stress. In the constant-load tests the stress increases throughout the test as the crack propagates, and the rate of crack propagation continuously increases. If the load range is reduced throughout a test (reduced-load test) so as to produce constant net-section stresses, the rate of crack growth will decrease throughout the test. (Author)

Retention of Text Information as a Function of the Nature, Timing, and Number of Quizzes by Richard C Anderson( Book )

2 editions published in 1974 in English and held by 2 WorldCat member libraries worldwide

In two experiments a total of 662 high school students read a prose passage, took a verbatim or paraphrase quiz, and a week later completed a verbatim or paraphrase delayed test. Taking a quiz significantly enhanced performance on the delayed test. Performance was consistently much higher on the verbatim than the paraphrase forms of quizzes and tests. Fitting the DATA RATHER WELL WAS A THEORY WHICH ASSUMES THAT A VERBATIM QUESTION IS BEST AT EVOKING RETRIEVAL OF PHONOLOGICALLY CODED INFORMATION IN SHORT TERM MEMORY WHEREAS A PARAPHRASE QUESTION IS BEST AT INSTIGATING TRANSFER OF THE INFORMATION INTO LONG-TERM, SEMANTIC MEMORY.

The behavior of sand in one-dimensional compression by Alfred Joseph Hendron( Book )

1 edition published in 1963 in English and held by 2 WorldCat member libraries worldwide

The behavior of sand in one-dimensional compression is investigated with both theoretical and experimental studies. The phenomenological aspects of one-dimensional behavior are discussed, such as stress-strain characteristics, energy absorption capacity, and coefficient of earth pressure at rest. The analytical study deals with the stress-strain relations of an idealized granular medium composed of elastic, equi-radii spheres in a face-centered cubic array. A new solution is derived for the behavior of the array when subjected to a monotonically increasing axial compressive stress for the comdition of zero radial strain. An experimental device is described which is capable of measuring the radial stresses developed in high-pressure, one-dimensional tests. Measurements of both the coefficient of earth pressure at rest and stressstrain properties are presented for four sands tested to an axial stress of 3,290 psi. Correlations are presented which compare the actual behavior of a rounded, uniform, quartz sand in one-dimensional and triaxial compression with the behavior suggested by the theoretical analysis.

Group and organizational factors influencing creativity( Book )

2 editions published between 1961 and 1962 in English and held by 2 WorldCat member libraries worldwide

This project investigates various training, group-structural, and leader variables which affect teamwork in tasks requiring creativity. Although a variety of group situations are investigated, the major emphasis is on the study of the type of team processes involved in research and development work. The first sub-project deals with methodological problems related to criterion development, and with training and task factors which influence individual and group creativity. The second investigates compositional factors which determine the effectiveness of individuals in groups. The third is concerned with leadership factors, such as the leader's perceptions and attitudes, and their effect on group performance under various conditions, such as intra-group conflict or external stress.

Theorems about beurling's generalized primes and the associated zeta function by Richard S Hall( Book )

1 edition published in 1967 in English and held by 2 WorldCat member libraries worldwide

Beurling defined a set, P, of generalized prime numbers as any non-decreasing unbounded sequence of real numbers which are greater than one. The multiplicative semi-group, N, generated by the elements of P is called the associated set of generalized integers. The functions Pi (x) and N (x) are defined, respectively, as the number of generalized prime and integers less than or equal to x. This paper is concerned with deducing the behaviour of Pi (x) from that of N (x)
Beyond conservation and liberation : the education of our aspirations by Linda S Wilson( Book )

1 edition published in 1992 in English and held by 2 WorldCat member libraries worldwide

This booklet presents the text of a lecture by Linda S. Wilson, president of Radcliffe College (Cambridge, Massachusetts) on the role of higher education as well as the responses, questions and discussion that followed. The lecture is preceded by a preface and an introduction by Morton W. Weir, chancellor of the University of Illinois at Urbana-Champaign (UIUC). In discussing the future of higher education during what she characterizes as a period of change, President Wilson argues against using a liberal-conservative continuum to think about higher education. Instead, she suggests that in order for higher education to successfully achieve what society aspires for it, higher education must (1) engage the full range of individuals' talents more completely, (2) "ignite the flame of confidence in ourselves and in higher education itself", and (3) give the public the capacity for thoughtful change. The lecture then looks at five key topics: access to higher education, strategies to inspire achievement and integrity, realignment of talents and tasks, improvement through new knowledge and technologies, and strategies to cope with the explosion of knowledge. The balance of the booklet presents three responses by administrators and scholars from UIUC and questions from the audience with their responses. (JB)
