Is advance knowledge of flow sizes a plausible assumption?

Vojislav Dukic, Sangeetha Abdu Jyothi, Bojan Karlas, Muhsen Owaida, Ce Zhang, Ankit Singla
2019 Symposium on Networked Systems Design and Implementation  
Most of this work assumes advance knowledge of flow sizes.  ...  These results indicate that a presumed lack of advance knowledge of flow sizes is not necessarily prohibitive for highly efficient scheduling, and suggest further exploration in two directions: (a) scheduling  ...  [7] , 2015 Thus, we explore this question in depth: Is advance knowledge of flow sizes a plausible assumption? Further, what happens when only information for some flows is available?  ...

Interstellar communication network. I. Overview and assumptions [article]

Michael Hippke
2019 arXiv   pre-print
This introduction to a series of papers makes the assumptions of the communication scheme explicit.  ...  If probes and planets with technological species exist in more than a handful of systems in our galaxy, it is beneficial to use a coordinated communication scheme.  ...  With these assumptions, we can argue for a range of plausible values of η−interesting (η i ), which is the fraction of stars which warrants sending a probe.  ...

In Defense of Unrealistic Assumptions

Satoshi Kanazawa
1998 Sociological theory  
I discuss a recent theory of the value of children by Friedman, Hechter, and Kanazawa (1994) to point out how assumptions differ from scope conditions and how empirically plausible and realistic hypotheses  ...  I contend that this criticism probably stems from the confusion of a theory's assumptions with its scope conditions.  ...  The empirical accuracy or realism of an assumption set is thus an inverse function of its size.  ...

Questioning ten common assumptions about peatlands

2017 Mires and Peat  
Sphagnum is the main 'ecosystem engineer' in peatlands; 8. a single core provides a representative palaeo-archive from a peatland; 9. water-table reconstructions from peatlands provide direct records of  ...  greater rates of net carbon accumulation; 4. different rules apply to tropical peatlands; 5. peat is a single soil type; 6. peatlands behave like sponges; 7.  ...  Given their area and the size of their C store , it is tempting to think of 'extra-tropical peatlands' as being mainly northern peatlands and, in turn, to think of these as Sphagnum bogs.  ...

On Heuristic Models, Assumptions, and Parameters [article]

Samuel Judson, Joan Feigenbaum
2022 arXiv   pre-print
These artifacts are products of the particular algorithmic techniques and theory applied to solve a problem once it has been modeled, and their nature can imperil thorough sociotechnical scrutiny of the  ...  We describe three classes of objects used to encode these choices and qualifiers: heuristic models, assumptions, and parameters, and discuss selection of the last for differential privacy as an illustrative  ...  It is mostly composed of qualitative methods, although written by a scientific expert who uses advanced mathematical tooling at points in the narrative.  ...

Extending the extended consciousness debate: perception, imagination, and the common kind assumption

James Deery
2021 Phenomenology and the Cognitive Sciences  
That is, the assumption that perception and imagination are of the same fundamental kind of mental event.  ...  I will argue that there are plausible alternative ways of conceiving of this relationship without drawing internalist metaphysical conclusions from their psychological theory.  ...  To my knowledge, proponents of the predictive approach offer no arguments for their endorsement of the common kind assumption.  ...

Should we test the model assumptions before running a model-based test? [article]

M. Iqbal Shamsudheen, Christian Hennig
2021 arXiv   pre-print
Although such an approach is often taken in practice, much of the literature that investigated this is surprisingly critical of it.  ...  Statistical methods are based on model assumptions, and it is statistical folklore that a method's model assumptions should be checked before applying it.  ...  the sample size and prior knowledge about the data ("if there is a small possibility of gross errors").  ...

2021 Institut für Demographie - VID  
A discussion of the baseline data, assumptions and model specifications is followed by a summary of key result on projected numbers of future migrants.  ...  This paper explores alternative future trajectories of international migration by applying a multiregional flow model to a new set of estimates of global bilateral migration flows developed by the second  ...  The research presented here is part of a large project by the Wittgenstein Centre on projecting global populations until 2100.  ...

Incompatible Assumptions: Barriers to Producing Multidisciplinary Knowledge in Communities of Scholarship

Corinne Bendersky, Kathleen L. McGinn
2007 Social Science Research Network

Utilitarianism on the front lines: COVID-19, public ethics, and the "hidden assumption" problem [article]

Charles Shaw, Silvio Vanadia
2022 arXiv   pre-print
How should we think of the preferences of citizens? Whereas self-optimal policy is relatively straightforward to produce, socially optimal policy often requires a more detailed examination.  ...  We argue that ethical expertise has a direct role to play in public discourse because it is hard to adopt a position on major issues like public health policy or healthcare prioritisation without making  ...  Assumption 1. The first assumption is that a lockdown is limited to L ≤ 1.  ...

QPE: Using assumption-based truth maintenance for qualitative simulation

A critical analysis of the assumptions underlying the formulation of maximum potential intensity for tropical cyclones [article]

Anastassia M. Makarieva, Andrei V. Nefiodov
2022 arXiv   pre-print
Here it is shown that a different and more general relationship between the same quantities derives straightforwardly from the gradient-wind balance and the definition of entropy, with the proportionality  ...  From the two equations combined it follows (1) that the E-PI maximum intensity is proportional to the radial gradient of local air temperature at the point of maximum tangential wind and (2) that for the  ...  So, the further development in Section 3b is of little value. Unbalanced flow at the point of maximum wind is not an assumption, single observation or output of a numerical model.  ...
