Developing an Activity-Based Costing Approach to Maximize the Efficiency of Customer Relationship Management Projects
Mahmood Shafiee, Golriz Amooee, Yaghoub Farjami
In today's competitive environment, profitability analysis is not just about looking at the profit and loss statement. It is more about knowing which of your customers are making y…
On the structure of the kappa-ring
Eaman Eftekhary, Iman Setayesh
We obtain lower bounds on the rank of the kappa ring of the Delign-Mumford compactification of the moduli space of curves in different degrees. For this purpose, we introduce a quo…
Gravitational Waves in a Spatially Closed deSitter Spacetime
Amir H. Abbassi, J. Khodagholizadeh, Amir M. Abbassi
Perturbation of gravitational fields may be decomposed into scalar,vector and tensor components.In this paper we concern with the evolution of tensor mode perturbations in a spatia…
Secure FSM- based arithmetic codes
Hashem Moradmand Ziyabar, Mahnaz Sinaie, Ali Payandeh +1
Recently, arithmetic coding has attracted the attention of many scholars because of its high compression capability. Accordingly, in this paper a method which adds secrecy to this…
New Compactifications of Eleven Dimensional Supergravity
Ali Imaanpur
Using canonical forms on S^7, viewed as an SU(2) bundle over S^4, we introduce consistent ansatze for the 4-form field strength of eleven-dimensional supergravity and rederive the…
