Snow Drifting

Unbalanced, or non-uniform, snow loads caused by snow drifting or sliding in cold regions with heavy snowfalls, can be a serious problem for the building industry. However, the methods for predicting snow distribution still need to be improved. Field observation is the most direct and reliable method to study snow distribution, but because the natural environment is uncontrollable and varies dramatically, sometimes conclusions may be confused under the influence of the many variables in the investigation. This paper proposes a snowing experiment approach using an outdoor snow–wind combined experiment facility for the study of snow distribution. The facility can produce a stable and controllable wind field and snowfall environment. Experiments which focused on snowdrift around a building were conducted during the winter to make an evaluation of the repeatability and reliability of the new approach. Finally, from the analysis of results, it was demonstrated that the experimental facility was stable and that the similarity criterion adopted for the snowing pattern was reliable. Especially, the minimum value of the friction speed ratio was suggested to ensure the test accuracy.

In this paper the authors present experimental confirmation of the feasibility of a new approach to the estimation of the four damping coefficients associated with a squeeze-film vibration isolator. The design and construction of the experimental facility is described in detail. A time-domain filtering algorithm is applied to process the displacement responses to single-frequency excitation and thus extract information on the linearized dynamics of the squeeze-film. The estimated coefficients are validated by comparing performance predictions with those obtained from spectrum analysis and from short-bearing theory. The significance of the results is discussed and suggestions are made for further work in this area.

Definition Of

Due to alarmingly high failure rates attributed to either a lack of project implementation or if implemented, poor results in organizations, many PM consulting organizations have begun developing their own PM maturity models (PM3) to assess organization maturity level, to identify their clients' PM maturity gap, and to provide a pathway by which their clients could move up the maturity scale and performance. Despite the many claims of PM3 assessment capabilities, the lack of success in market adoption of PM3 models suggests the need for more studies to identify if these are due to the many definition of project success, the lack of consensus of what the components of PM3 should be, or the increasing expectations of the PM community. Thus, this chapter aims to identify the reasons behind differing organizations' views on the dimension of project success, components of PM3's direct impact on organizational performance, and how PM maturity can be measured and correlated to the various level of organizational success with a new approach known as DPM3.

This chapter looks at how the timely development of an interdisciplinary archaeology (modern conflict archaeology) of the First World War from the late 1990s offered a comprehensive and nuanced way of investigating the many interlocking military and cultural aspects of the Arab Revolt and its aftermath. Ephemeral archaeological traces in the sands of southern Jordan, it was hoped, would speak to the origins of modern guerrilla warfare which itself contributed to the shaping of the Middle East after 1918. The new approach showed the power of objects to create and transmit impressions and evaluations of the Revolt and its personalities—not least by the catalysing effects of finding similar items during excavations of the original landscapes whence all such objects derived their historical significance. The desert, so apparently empty of information and insight, would prove to be full of both. The key to deciphering its archaeological message lay in understanding the landscape, its layers and its objects—a quest which began with the largest artefact of all, the Hejaz Railway.

AbstractThe proposed methodology is based on a (global and multi-criteria) simplified environmental but thorough assessment. In this stage we do not directly give the solution to designers. It will therefore translate the results of evaluation design axes, but in general, the lines proposed are inconsistent or contradictory. Therefore, what we find is a compromise given to the solution. The challenge we are facing in an industrial reality is that one should not go for a compromise solution. TRIZ (Teorija Reshenija Izobretateliskih Zadatch) or the theory of solving inventive problems, in the field, will be reformulated and go through the contradiction matrix and then intervene with the principles of interpretation resolutions to give possible solutions. To assist small and medium enterprises (SMEs) in their product development, the objective of this paper is to propose a methodological approach named Ecatriz, that will allow us to achieve our eco-innovative goal. The applicability of this method is justified by the many contradictions in the choices in a study of the life cycle. As a starting point, a qualitative multi-criteria matrix will allow the prioritization of all impacts on the environment. A customized implementation of the inventive TRIZ (Teorija Reshenija Izobretateliskih Zadatch, Russian acronym for theory of solving inventive problems) principles will help us choose eco-innovative solutions. To that end, we have created a new approach named Ecatriz (ecological approach TRIZ), based on a new contradiction matrix. It was tested in various contexts, such as the “24 h of Innovation” competition and eco-innovative patents.

Ranging Model

A brand new approach to the understanding of breast cancer (BC) is urgently needed. In this contribution, the etiology, pathogenesis, and treatment of this disease is approached from the new pH-centric anticancer paradigm. Only this unitarian perspective, based upon the hydrogen ion (H+) dynamics of cancer, allows for the understanding and integration of the many dualisms, confusions, and paradoxes of the disease. The new H+-related, wide-ranging model can embrace, from a unique perspective, the many aspects of the disease and, at the same time, therapeutically interfere with most, if not all, of the hallmarks of cancer known to date. The pH-related armamentarium available for the treatment of BC reviewed here may be beneficial for all types and stages of the disease. In this vein, we have attempted a megasynthesis of traditional and new knowledge in the different areas of breast cancer research and treatment based upon the wide-ranging approach afforded by the hydrogen ion dynamics of cancer. The concerted utilization of the pH-related drugs that are available nowadays for the treatment of breast cancer is advanced.

Translation into English has recently been completed for excerpts on ear and craniofacial anthropometry from an innovative, unpublished Bulgarian-language doctoral thesis written in 1986 by a plastic surgeon, M. M. Madzharov, MD-PhD; MD-SC. Most remarkable among the many benefits of the translation was revelation of heretofore unavailable text descriptions for 49 dimensions. Of these, 43 explain the titles and abbreviations with summary statistical data on ear measurements for young adults that were published in 1989 in the English language. Especially valuable among these data were four new and unique, long-axial ear lengths, all measured from a common ear landmark. These could locate “station planes” for cross-section views of human ears, similar to those for 3-D coordinate systems in aircraft and spacecraft fuselage engineering. Examples explaining the concepts and values of such a new approach to ear anthropometry are herein introduced, described and illustrated, together with previously recommended improvements in ear anthropometry notation and illustration, a virtual Ear Primary View Plane, a section plane through the ear long axis, newly introduced “semi-width” measurements extending perpendicular to the aforementioned section plane, new concepts of “view depths,” which are measured perpendicularly from the Ear Primary View Plane toward ear surfaces and a previously described three-axis aircraft motion analogy for defining static ear orientation. These innovative approaches are advocated for adoption by future researchers, designers of related hardware, modelers and standards developers.

One of the many important ideas that we teach in the mathematics and prealgebra curricula is the concept of order of operations. However, it is a concept that many students consistently forget from year to year. Students invariably solve problems from left to right, regardless of the hierarchy associated with the operations. This article outlines a new approach to teaching this important concept.

Age-related macular degeneration (AMD) is the leading cause of visual loss in older population. Angiogenesis is an important factor associated with the development of CNV due to AMD. Treatment of CNV with intravitreal anti-VEGF monotherapy is currently the standard of care. However, not all patients respond to monotherapy, and modified anti-VEGF treatment regimen and combination therapy may target reducing treatment frequency or improving visual outcome. This paper reviews the many clinical trials that have been performed utilizing several treatment regimens. While many trials have shown that this variable therapy is justifiable, further study is required to determine correct regimens and dosage.

Clustering is one of the essential strategies in data analysis. In classical solutions, all features are assumed to contribute equally to the data clustering. Of course, some features are more important than others in real data sets. As a result, essential features will have a more significant impact on identifying optimal clusters than other features. In this article, a fuzzy clustering algorithm with local automatic weighting is presented. The proposed algorithm has many advantages such as: 1) the weights perform features locally, meaning that each cluster's weight is different from the rest. 2) calculating the distance between the samples using a non-euclidian similarity criterion to reduce the noise effect. 3) the weight of the features is obtained comparatively during the learning process. In this study, mathematical analyzes were done to obtain the clustering centers well-being and the features' weights. Experiments were done on the data set range to represent the progressive algorithm's efficiency compared to other proposed algorithms with global and local features
