Growth Characteristics of Kangal and Akbas Turkish Shepherd Dogs
No full textThis study was performed to compare the growth characteristics of Kangal and Akbas Turkish shepherd dogs. Live weight records of 141 puppies at birth, 86 puppies at weaning, 68 puppies at 6 and 12 months of age and four different body measurements of 68 dogs at different ages were used for determining growth characteristics. The least squares method was used for statistical analysis. Least squares mean weights of Kangal and Akbas puppies at birth, weaning, and 6 and 12 months of age were 557.21 and 506.95 g, 5657.35 and 4457.70 g, 21.58 and 19.38 kg, 40.89 and 37.66 kg, respectively. At age I year, in Kangal and Akbas dogs. the average shoulder height was 70.54 and 65.91 cm, rump height was 71.27 and 66.66 cm, body length was 64.05 and 59.43 cm, and body circumference was 78.10 and 71.86 cm, respectively. In conclusion, it was determined that Kangal dogs were superior to Akbas dogs with respect to all growth characteristics (P < 0.05)
The analogue of grad-div stabilization in DG methods for incompressible flows: Limiting behavior and extension to tensor-product meshes
No full textSchroeder, Philipp W./0000-0001-7644-4693WOS: 000442638700037grad-div stabilization is a classical remedy in conforming mixed finite element methods for incompressible flow problems, for mitigating velocity errors that are sometimes called poor mass conservation. Such errors arise due to the relaxation of the divergence constraint in classical mixed methods, and are excited whenever the spatial discretization has to deal with comparably large and complicated pressures. In this contribution, an analogue of grad-div stabilization for Discontinuous Galerkin methods is studied. Here, the key is the penalization of the jumps of the normal velocities over facets of the triangulation, which controls the measure-valued part of the distributional divergence of the discrete velocity solution. Our contribution is twofold: first, we characterize the limit for arbitrarily large penalization parameters, which shows that the stabilized nonconforming Discontinuous Galerkin methods remain robust and accurate in this limit; second, we extend these ideas to the case of non-simplicial meshes; here, broken grad-div stabilization must be used in addition to the normal velocity jump penalization, in order to get the desired pressure robustness effect. The analysis is performed for the Stokes equations, and more complex flows and Crouzeix-Raviart elements are considered in numerical examples that also show the relevance of the theory in practical settings.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
Evaluation of the Uncertainties Related to the Geotechnical Design Method and Its Consideration in Reliability Based Design
No full textThe findings of a joint ISSMGE TC 205/TC 304 discussion group on the evaluation of model uncertainties, i.e. uncertainties related to the chosen geotechnical design method, are presented. The discussion revealed the importance of model uncertainty assessment due to the high sensitivity of many geotechnical design methods for the accuracy of the adopted model. In case of geotechnical designs in which the design quantities are clearly defined, model uncertainties may be considered by a model factor representing the bias of the predicted to the real behavior. The real behavior itself can be derived from well documented prototype and model scale field and laboratory tests. Model factors can be used in rigorous reliability based design but also in LRFD formats adopted by many geotechnical design codes. However, for complex design situations model uncertainty assessment remains difficult. Moreover, model uncertainties are affected by extraneous uncertainties such as spatial soil variability or uncertainties due to test performance which cannot be separated
G-Rank: Unsupervised Continuous Learn-to-Rank for Edge Devices in a P2P Network
No full textRanking algorithms in traditional search engines are powered by enormous training data sets that are meticulously engineered and curated by a centralized entity. Decentralized peer-to-peer (p2p) networks such as torrenting applications and Web3 protocols deliberately eschew centralized databases and computational architectures when designing services and features. As such, robust search-and-rank algorithms designed for such domains must be engineered specifically for decentralized networks, and must be lightweight enough to operate on consumer-grade personal devices such as a smartphone or laptop computer. We introduce G-Rank, an unsupervised ranking algorithm designed exclusively for decentralized networks. We demonstrate that accurate, relevant ranking results can be achieved in fully decentralized networks without any centralized data aggregation, feature engineering, or model training. Furthermore, we show that such results are obtainable with minimal data preprocessing and computational overhead, and can still return highly relevant results even when a user’s device is disconnected from the network. G-Rank is highly modular in design, is not limited to categorical data, and can be implemented in a variety of domains with minimal modification. The results herein show that unsupervised ranking models designed for decentralized p2p networks are not only viable, but worthy of further research.https://github.com/awrgold/G-RankComputer Scienc
