Microcanonical Simulation of Complex Actions: The Wess Zumino Witten Case
We present the main results of our microcanonical simulation of the Wess
Zumino Witten action functional. This action, being highly non-trivial and
capable of exhibiting many different phase transitions, is chosen to be
representative of general complex actions. We verify the applicability of
microcanonical simulation by successfully obtaining two of the many critical
points of the Wess Zumino Witten action. The microcanonical algorithm has the
additional advantage of exhibiting critical behaviour for a small
lattice. We also briefly discuss the subtleties that, in general, arise in
simulating a complex action. Our algorithm for complex actions can be extended
to the study of
D-branes in the Wess Zumino Witten action.Comment: 5 figure
Does knowledge based psychological ownership matter? Transformational leadership and knowledge hiding: A proposed framework
The prevalent and negative impact of knowledge hiding behaviour among employees has called the attention of both practitioners and researchers to begin investigations on its causes, and other factors that influence it on both the targets and perpetrators. Some of the possible suggested antecedents of knowledge hiding studied include trust, job characteristic, organisational culture, and workplace environment. Despite these studies, few have attempted to investigate the influence of leadership, particularly, transformational leadership on knowledge hiding. Previous studies also indicated conflicting results, and the mechanisms through which transformational leadership influences knowledge hiding are not adequately addressed. Therefore, mediator variable is suggested. Hence, this paper proposes knowledge psychological ownership as a potential mediator on the relationship between transformational leadership and knowledge hiding behaviour of an employee in the organization. We hereby argue that transformational leadership through knowledge psychological ownership will influence employees to refrain from the knowledge hiding behaviour that may negatively affect the organisation and encourage knowledge sharing to improve the performance of the organization
Successful inoculation of Artemia and production of cysts in the coastal saltpans of Bangladesh II
Bangladesh has no naturally occurring Artemia, and all the growing shrimp hatcheries of the country depend entirely on import of cysts from foreign countries. Following successful inoculation of Artemia and production of cysts for the first time in this country in a coastal saltpan (at Chanua, Banskhali) by the senior author (in 1989-90), a similar second attempt was made under this programme in a saltpan (1000 m super(2)) of Demoshia, Chakaria, Cox's Bazar, Bangladesh between January and April 1992. A total of 1639.9 g (dry weight) of cysts (i.e. 5.46 kg DW/ha/month) have been produced using the Red Jungle Brand, whereas the previous attempt obtained 517 g of cysts (i.e. 2.07 kg DW/ha/month) using the Great Salt Lake Brand
Handwritten Signature Verification using Deep Learning
Every person has his/her own unique signature that is used mainly for the purposes of personal
identification and verification of important documents or legal transactions. There are two kinds of signature
verification: static and dynamic. Static(off-line) verification is the process of verifying an electronic or document
signature after it has been made, while dynamic(on-line) verification takes place as a person creates his/her
signature on a digital tablet or a similar device. Offline signature verification is not efficient and slow for a large
number of documents. To overcome the drawbacks of offline signature verification, we have seen a growth in
online biometric personal verification such as fingerprints, eye scan etc. In this paper we created CNN model
using python for offline signature and after training and validating, the accuracy of testing was 99.70%
Maximum temperature for an Ideal Gas of Kac-Moody Fermions
A lagrangian for gauge fields coupled to fermions with the Kac-Moody group as
its gauge group yields, for the pure fermions sector, an ideal gas of Kac-Moody
fermions. The canonical partition function for the case is shown to
have a maximum temperature , where is the
coupling of the super charge operator to the fermions. This result is
similar to the case of strings but unlike strings the result is obtained from a
well-defined lagrangian.Comment: Needs subeqnarray.sty; To be published in Phys. Rev. D, Dec 15, 1995.
