Towards an Automated Design of Application-specific Reconfigurable Logic
Full text linkReconfigurable logic is known to have the potential to provide better
solutions than direct ASIC implementations or processors in some situations.
A necessary prerequisite for area advantages compared to ASICs or a better
energy efficiency than processors is an application specific design of the
reconfigurable unit.
Adapting it to the specific requirements of an application helps to compensate
for the area and speed penalty introduced by reconfigurability.
The data paths of reconfigurable units are best suited for data flow oriented
tasks, but for many applications, both control flow and data flow must be
handled, so a integration of the reconfigurable unit into a processor
environment is an appropriate choice.
By analysing the existing design flow and integration possibilities for
reconfigurable units, a basis for discussing possible automation schemes
and a standardised interface is defined.
Possible future research could investigate an automated design support for the
building blocks of reconfigurable units and the definition of a standard
processor interface for some classes of reconfigurable units
Did Zipf anticipate spatial connectivity structures?
No full textAn avalanche of empirical studies has addressed the validity of the rank-size
rule (or Zipf ’s law) in a multicity context in many countries. Under which conditions (eg,
sample size, spatial scale) this ‘law’ holds remains as yet largely underinvestigated, while
spatial network constellations also deserve more attention. Against this background, we
investigate the relationship between network connectivity and the rank-size rule (or Zipf ’s
law) in an urban economic network constellation. In particular, we address the following
methodological issues: (i) the (aggregate) behavioural foundation underlying the rank-size
rule (Zipf ’s law) in the light of spatial-economic network theories (eg, entropy maximization,
spatial interaction theory); (ii) the nature of the analytical relationship between
social-spatial network analysis and the rank-size rule (Zipf ’s law). We argue that the ranksize
rule is compatible with conventional economic foundations of spatial network models.
We test the sensitivity of rank-size rules for changes in scale, functional forms, time periods,
and connectivity structures. Our application uses an extensive spatiotemporal panel
database on the evolution of the urban population in Germany. We test the relevance of
the rank-size rule (Zipf ’s law), and—in parallel—the related ‘socioeconomic’ connectivity
in these urban networks. In particular, we will show that Zipf ’s law (ie, with the rank-size
coefficient equal to 1) is only valid under particular conditions of the sample size

Zipfs Law for Cities: A Cross Country Investigation
Full text linkThis paper assesses the empirical validity of Zipf¿s Law for cities, using new data on 73countries and two estimation methods ¿ OLS and the Hill estimator. With either estimator,we reject Zipf¿s Law far more often than we would expect based on random chance; for 53out of 73 countries using OLS, and for 30 out of 73 countries using the Hill estimator. TheOLS estimates of the Pareto exponent are roughly normally distributed, but those of the Hillestimator are bimodal. Variations in the value of the Pareto exponent are better explained bypolitical economy variables than by economic geography variables.Cities, Zipf¿s Law, Pareto distribution, Hill estimator
Moral Good, the Beatific Vision, and God’s Kingdom Writings by Germain Grisez and Peter Ryan, S.J.. Edited by Peter J. Weigel
No full textFor close to half a century, the work of Germain Grisez has been highly influential, and his writings continue to receive considerable attention from philosophers and theologians of diverse viewpoints. His co-author for this work is the professor and noted moral theologian Fr. Peter Ryan, S.J., currently the executive director of the Secretariat of Doctrine and Canonical Affairs of the United States Conference of Catholic Bishops (USCCB). These two eminent scholars explore fundamental questions about Christian eschatology, moral theory, the purpose of human life, and the promise of human fulfilment. The authors examine Christian teaching on the final destiny of persons, investigating the meaning of God's kingdom, the hope of the beatific vision, and the centrality of moral goodness and divine grace in one's final end. This work is an ideal source for students, scholars, ministers and lay persons interested in basic questions of Christian theology, the philosophy of religion, ethical theory, and Catholic doctrin

Zipf and the size distribution of firms
No full textBased on a sample of 50441 independent UK companies of all sizes covering all sectors of the UK economy, the size distribution of companies is close to lognormal, even though the hypothesis of lognormality can be rejected statistically. A Zipf plot shows that the Pareto distribution is a poor fit to the upper 5% tail.
