V-grooved quartz substrates are manufactured by glass molding press and the pitch errors of the molded quartz fiber array blocks are statistically investigated. The V-grooved carbon molds of 8 and 16 channels and 250 μm in pitch are machined and then quartz substrates are molded on the V-grooved carbon molds by glass molding press. The pitch errors of X, Y and diagonal axis are measured and then statically analyzed. It is demonstrated that the V-grooved quartz fiber array blocks of 8 and 16 channels and 250 μm in pitch can be manufactured by glass molding technology without significant pitch errors.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

Performance on a German version of the Rey Auditory-Verbal Learning Test (AVLT) was investigated for 64 juvenile patients who were subdivided in 6 clinical groups. In addition to standard evaluation of AVLT protocols which is usually confined to items recalled correctly, an error analysis was performed. Differentiating between total errors (TE), repetition errors (RE), and misnamings (ME), substantial differences between clinical groups could be demonstrated. It is argued that error analysis of verbal memory and learning enriches the understanding of neuropsychological syndromes, and provides additional information for diagnostic and clinical use. Thus, it is possible to gain a more accurate picture so that patients can be appropriately retrained, and research into the functional causes of memory and learning disorders can be intensified.

What is the work that miracles do in American Charismatic Evangelicalism? How are miracles something that are at once unanticipated, and yet worked for? Finally, what do miracles tell us about Christianity, and even about the category of religion? A Diagram for Fire engages with those questions through an detailed ethnographic study of the Vineyard, a Southern-California originated American Evangelical movement known for believing that biblical-style miracles are something that all Christians can perform today. This book sees the miracle a resource and a challenge to institutional cohesion and human planning, and as an immanently-situated and fundamentally social means of producing change that operates through taking surprise and the unexpected, and using it to reimagine and reconfigure the will. A Diagram for Fire shows how this configuration of the miraculous shapes typical Pentecostal and Charismatic religious practices such as prophesy, speaking in tongues, healing, and battling demons; but it also shows how the miraculous as a configuration also ends up shaping other practices that seem far from the miracle, such as a sense of temporality, music, reading, economic choices, and both conservative and progressive political imaginaries. This book suggests that the open potential of the miracle, and the ironic constriction of the miracle’s potential through the intentional attempt to embrace it, has much to tell us not only about how contemporary Pentecostal and Charismatic Christianity both functions and changes, but about an underlying mutability that plays an important role in Christianity and even in religion writ large.
