Abstract. The combined cyclic fatigue is computationally simulated by a judicious combination of three independent computational modules: composite mechanics, a multi-factor equation module (MFIM) and probabilistic algorithm (FPI). The inputs to each module are constituent material properties, processing variables, loading and environmental conditions and probabilistic variables. The composite fatigue is simulated by considering an inplane loaded-component in a structure which is subjected to fatigue because of cyclic loading. Typical results show that the low probability fatigue cycle is about 50 percent of the corresponding static value.

Methodologically, the IIASA research program on Regional Development reflects the general attitude of the majority of regional scientists. Among other things, this means that the models developed deal with discrete sets of regions or locations. For planning purposes, this approach is extremely efficient, due to computational advantages. On the other hand, systematic information about regional structures, of the geometric flavor associated with classical location theory, is hard to obtain if one discretizes space from the outset. \n\nTo complement this main stream of regional analysis, two scientists currently trying to revive continuous modeling of the space economy, Martin J. Beckmann and Tonu Puu, were invited to IIASA in September 1979. They started writing a comprehensive monograph intended to present the state-of-the-art in the field of continuous regional modeling. The completion of such an extensive work was not possible in the brief period of three weeks. \n\nThe authors are currently continuing work on the project. This paper by Tonu Puu constitutes one chapter of the forth-coming monograph. It was completed during his visit to IIASA in August 1982 and follows the chapter circulated as CP-82-11. \n\nWhereas the preceding chapters dealt with commodity trade models with unique patterns of flow, the present one describes a simple interaction model cast in a continuous format. Given a specified need for communication and accommodation, optimal land use (balancing traffic congestion and population crowding) is discussed. In addition to the problems of optimal communication routes, the paper focuses on equilibrium population distributions such that communication and housing costs are in balance.

SOIL INTERACTION MODELThe prerequisite for ecoefficient wood harvesting is an appropriate planning method, which permits the evaluation of the operational and socio-economic costs and outcomes for the planned actions in advance.Operational planning is becoming computerised, which implies that the planning programs and algorithms are reliable enough to lead to acceptable decisions.Too simplistic models and decision-making rules may lead to the selection of incorrect alternatives.Improved models and modelling techniques are needed in order to fit together the scattered knowledge on wheel soil interaction and its consequences to the operations, environment and society.The report is based on 8 state of the art reports presented in Appendix Reports No. 1 to 8. and supported by three software manuals, where the data have been collected into interactive submodels, Appendix Reports No. 9 -11, see Table 1.

This paper introduces a novel conceptual foundation for Social Set Analysis, the Social Interaction Model. It contributes to the state-of-the-art theory in Big Social Data by extending the existing Social Data Model through proposal of an improved concept which is formally grounded in set theory and relational algebra. The concept of Interactions based on one initial Action between two social media Actors, and zero or many Reactions, all referencing the initial Action, is presented. Furthermore, temporal and spatial dimensions are included as a core component of the proposed model, thus streamlining data analytics tasks in the realm of Social Set Analysis. Key differences between the existing Social Data Model and the Social Interaction Model contributed in this paper are the inclusion of non-textual artifact content types, the unification of a previously bipartite Social Data Model, the deprecation of an empirically vague notion of Activities, and improved interoperability between data sources.

Oceanic environmental models have reached a point of sophistication whereby they depict numerous observed hydrographic features. Advances in numerical techniques and computer processing capabilities have helped achieve these goals. However, sparse oceanographic data have historically limited ocean forecast modeling efforts. Recent satellite programs utilizing passive and active microwave instruments (SEASAT-A, Nimbus-G, and GEOS-3) have indicated a potential to produce a quantum leap in satisfying numerical model input parameter requirements. Previous results and the potential of scatterometer, Scanning Multichannel Microwave Radiometer (SMMR) and altimeter derived measurements with regards to ocean models will be reviewed. New efforts directed at sea surface temperature (SST) and conversion to sea surface heights and input to ocean models will also be explored.

<div><p>Multi-professional teams care for sick newborns, but nurses are the primary caregivers, making nursing care documentation essential for delivering high-quality care, fostering teamwork, and improving patient outcomes. We report on an evaluation of vital signs documentation following implementation of the comprehensive newborn monitoring chart using interrupted time series analysis and a review of filled charts. We collected post-admission vital signs (Temperature (T), Pulse (P), Respiratory Rate (R) and Oxygen Saturation (S)) documentation frequencies of 43,719 newborns with a length of stay > 48 hours from 19 public hospitals in Kenya between September 2019 and October 2021. The primary outcome was an ordinal categorical variable (no monitoring, monitoring 1 to 3 times, 4 to 7 times and 8 or more times) based on the number of complete sets of TPRS. Descriptive analyses explored documentation of at least one T, P, R and S. The percentage of patients in the no-monitoring category decreased from 68.5% to 43.5% in the post-intervention period for TPRS monitoring. The intervention increased the odds of being in a higher TPRS monitoring category by 4.8 times (p<0.001) and increased the odds of higher monitoring frequency for each vital sign, with S recording the highest odds. Sicker babies were likely to have vital signs documented in a higher monitoring category and being in the NEST360 program increased the odds of frequent vital signs documentation. However, by the end of the intervention period, nearly half of the newborns did not have a single full set of TPRS documented and there was heterogenous hospital performance. A review of 84 charts showed variable documentation, with only one chart being completed as designed. Vital signs documentation fell below standards despite increased documentation odds. More sustained interventions are required to realise the benefits of the chart and hospital-specific performance data may help customise interventions.</p></div>

This paper develops a theoretical model which describes means for increasing the number of interactions and for enhancing social presence in an online learning environment. This model considers Anderson’s model of online learning and the variables indicated in the literature that might enhance social presence. These variables are: presence of others and response times. They were selected prioritising those that could affect the categories of indicators of social presence described by Garrison, Anderson and Archer. The model identifies three interface features that enhance social facilities: images, animation and text. Images, animation and text are used to portray social information while animation is used to present system feedback. In addition, this paper highlights the affective-motivational role of images, which might be crucial to students’ satisfaction with the interface in an online course. Four experiments were designed to test and validate the corresponding concepts. The results show that the use of images, animation and text to portray information about the others fosters web mail and instant mail interaction among students. In addition, the use of animation providing system feedback to incoming messages contributes to an increase in the number of interactions.

A spin model called the anisotropic exchange-interaction model is proposed. The Potts model, the exchange-interaction model, and the spin-1/2 anisotropic Heisenberg model are special cases of the proposed model. Thermodynamic properties of the model on the bcc and the fcc lattices are determined by the constant-coupling approximation.
