Collatz Convergence Proof (A Structural Resonance Approach) - Author 'HyunJun Yang(aka LOEN)'
No full textThis project presents a structural proof of the Collatz Conjecture by decomposing its arithmetic into a resonance model of Mersenne numbers and binary reduction cycles. The variables ‘karma (k)’ and ‘residue (r)’ represent division steps and final convergence. Through reverse induction, the structure inherently leads to 1, revealing a deeper pattern of convergence both mathematically and socio-structurally.

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Opportunities and constraints in the use of simulation on low cost ARM-based computers
No full textThe whole-building simulation community has habitually demanded greater computational resources and developers and researchers have responded with a myriad of approaches to address this demand. However, much of the work of creating and evolving models takes a fraction of the available computational power. This paper considers the deployment of simulation at the other extreme of computational cost e.g. ARM based products such as the Raspberry Pi and the BeagleBone Black. This paper reports on the porting of the ESP-r whole-building suite to ARM. It describes the modifications required to the simulation software as well as to the compilation tool-chain and computing environment to support compilation and deployment. It discusses the performance implications of model complexity and adjustments to methodologies required as well as the user reactions. It also describes how research based on tools such as MATLAB can be hosted on these alternative computer platforms

Effect of blade curvature on the hemolytic and hydraulic characteristics of a centrifugal blood pump
No full textAims: Impeller design has a significant impact on the overall performance of a blood pump. In this study, the effect of the blade curvature was investigated by performing in silico and in vitro studies on a recently developed centrifugal blood pump. Methods: A computational fluid dynamics study was performed for the flow rates of 3-5 L/min at 2000 r/min. The computational fluid dynamics model was also applied on the US Food and Drug Administration (FDA) benchmark blood pump to validate our computational method. The relative hemolysis index was calculated with the Eulerian hemolysis estimation method for five impellers with the wrap angles ranging from 0° to 240°. Hydraulic experiments were conducted for the validation of computational fluid dynamics results. In addition, the curved-blade impeller (120°) and the straight-blade impeller (0°) were evaluated with in vitro hemolysis tests using human blood. Results: The wrap angle of 120° provided the best hydraulic and hemolytic performance. Pump achieved the physiologic operating pressures and flows with 85-115 mmHg at 2.5-5.9 L/min. Compared to the straight-blade impeller, the 120° model reduces the relative hemolysis index and the plasma-free hemoglobin near 72.8% and 56.7%, respectively. Comparison of in silico and in vitro results indicated the similar trend to the blade curvature. Conclusion: Introducing a blade curvature enhanced the hydrodynamic and hemolytic performance compared to the straight-blade configuration for the investigated centrifugal blood pump. The findings of this study provide new insights into centrifugal blood pump design by examining the influence of the blade curvature.</p
Glosa do wyroku Sądu Apelacyjnego w Katowicach z dnia 7 października 2011 r., II AKa 366/11
No full textPrzedmiotem niniejszej glosy jest stanowisko Sądu Apelacyjnego w Katowicach,
wyrażone w wyroku z dnia 7 października 2011 r., II AKa 366/11, w zakresie zawartego w nim rozstrzygnięcia dotyczącego orzeczenia obowiązku naprawienia szkody
w przypadku orzeczenia skazującego sprawcę na karę pozbawienia wolności, której
wykonanie zostało warunkowo zawieszone. W publikacji autor, dokonując oceny
przedmiotowego orzeczenia, poddaje analizie problematykę związaną z wyborem
właściwej podstawy prawnej orzekanego przez Sąd obowiązku naprawienia szkody,
a także jego zakresu przedmiotowego oraz określenia sposobu i terminu wykonania obowiązku naprawienia szkody. Jednocześnie w publikacji poruszono aspekt
stosunku środka karnego obowiązku naprawienia szkody wobec środka karnego,
w postaci nawiązki z art. 46 § 2 k.k. Ponadto w publikacji, oprócz uwag de lege lata,
przedstawiono postulaty de lege ferenda w zakresie objętym przedmiotem głosowanego orzeczenia.The gloss discusses the position of the Court of Appeal in Katowice expressed in the
sentence II AKa 366/11 of 7 October 2011 regarding the obligation to redress the
damage in case the person causing it is sentenced to conditionally suspended penalty
of imprisonment. The author of the publication assesses the sentence and analyzes
the issue connected with the choice of the appropriate legal grounds for the that
obligation to redress the damage as well as its scope and the way and time limit of the
obligation to redress the damage. The author also discusses the aspect of the relation
between the penalty of the obligation to redress the damage and the supplementary
penal measure ordering a payment to the injured person in accordance with Article
46 § 2 of the Criminal Code. Moreover, apart from comments de lege lata, the author

Control of macrophytes by grass carp (ctenopharyngodon idella) in a Waikato drain, New Zealand
No full textHornwort (Ceratophyllum demersum L.) and other aquatic macrophytes have historically been mechanically removed from the Rangiriri drain and Churchill East drain to maintain drain efficiency. As an alternative control method for the high plant biomass that accumulates at the end of summer, the effect of stocking diploid grass carp (Ctenopharyngodon idella L.) on the aquatic vegetation was evaluated in these Waikato drainage systems. At the start of the trial, both drains had a low diversity of aquatic macrophytes, and of the nine species (including the emergents), seven were exotic. Two months after grass carp were released to Churchill East drain (the treated drain) the four submerged and floating macrophyte species became scarce in the main drain. Over the same period, these species increased in biomass in Rangiriri drain (the untreated drain), where hornwort became dense and surface-reaching and remained so for the duration of the trial. However, grass carp did not control submerged vegetation in smaller side drains or the shallow, upper parts of the main drain, or the marginal sprawling species and emergent species. The cost of leasing the grass carp was similar to the cost of clearing the drains mechanically, but grass carp provided continuous weed control. However, subsequent to this trial, 62 dead grass carp were found in Churchill East drain in February 2001, and weed cover subsequently increased. This illustrates that grass carp management in New Zealand agricultural drains can be problematic due to periodic fish kills
