A SPECIFIC COBB-DOUGLAS MODEL AND THE PERFORMAMNCE OF PUBLIC ADMINISTRATION IN THE FRAMEWORK OF MANAGEMENT CONTROL MECHANISM
The position of public administrations at the centre of major socio-economic development projects means that these administrations are strongly requested to perform their productivity mechanisms. Any failure affects systematically development and society, explaining why management control is an essential tool for mitigating risks and failures and increasing the performance and productivity possibilities of these administrations. Thus, management control will be considered through a carefully proposed Cobb-Douglas model adapted to the public sector of the Moroccan administration. The importance and the originality of this work reside respectively in the scientific engineering position of the Cobb-Douglas formalism and in the interpretation that we give to the production scale factors K and L for a rational and reliable adaptation
Toric Geometry and String Theory Descriptions of Qudit Systems
In this paper, we propose a new way to approach qudit systems using toric
geometry and related topics including the local mirror symmetry used in the
string theory compactification. We refer to such systems as (n,d) quantum
systems where and denote the number of the qudits and the basis states
respectively. Concretely, we first relate the (n,d) quantum systems to the
holomorphic sections of line bundles on n dimensional projective spaces CP^{n}
with degree n(d-1). These sections are in one-to-one correspondence with d^n
integral points on a n-dimensional simplex. Then, we explore the local mirror
map in the toric geometry language to establish a linkage between the (n,d)
quantum systems and type II D-branes placed at singularities of local
Calabi-Yau manifolds. (1,d) and (2,d) are analyzed in some details and are
found to be related to the mirror of the ALE space with the A_{d-1} singularity
and a generalized conifold respectively.Comment: 12 pages,latex, 2 figures. Accepted for publication in Journal of

Conformal Liouville Theory from D=10 Parallelizable type IIB supergravity with a 5-form Ramond-Ramond.
We investigate the effect of parallelizable property on supergravity equations of motion, therefore we will extract the exact solutions of Conformal Liouville Theory from D=10 Parallelizable IIB Keywords: Conformal Liouville Theory, Parallelizability, supergravity
