this paper aims to investigate the effect of budget deficit shock on government spending in indonesia. for this propose, this reasearch uses an alternative error correction model based on loss function of government spending. the model assumes the short run disequilibrium, in which shock variables may play an important role. a spesific loss function model is applied to develop the long run gove...

Background: Occupational noise-induced hearing loss (ONIHL) is a hearing disorder that affects workers all over the world. Preconditioning with several mild or less potent stressors will effectively prevent the development of noise-induced hearing loss. This study investigated the possible preventive effects of normobaric hyperoxia preconditioning on preventing the noise-induced hearing impairm...

A man with metastatic carcinoma of the colon had a bone scan which revealed urinary retention in the left kidney. Ten months later, a Tc-99m-DTPA renai glomerular study showed the left kidney to have only 8% of total renal function. Fifteen months after that, (he same kidney demonstrated 9% of total function, while the right kidney had evolving obstruction due to his neoplasm. The case sh...

In this research, we propose a bi-objective model for the economic-statistical design of the X-bar and S control charts. The model minimizes out-of-control average time to signal as well as minimizing mean hourly loss-cost where it incorporates the Taguchi loss function. Statistical constraint is considered in the model to achieve desired in-control time to signal. A non-dominated sort...

in this paper, the static var compensator (svc) has been used to improve dynamic behaviour of power system. to do this, a new objective function is formulated considering power loss reduction, voltage profile improvement and loadability margin decrease. other contribution of this research is proposing a novel structure for particle swarm optimization (pso) algorithm through modifying the initia...

optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. the distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

In this note we prove that, if the cost function satisfies some necessary structural conditions and the densities are bounded away from zero and infinity, then strictly c-convex potentials arising in optimal transportation belong to W 2,1+κ loc for some κ > 0. This generalizes some recents results [10, 11, 24] concerning the regularity of strictly convex Alexandrov solutions of the Monge-Ampère...

We solved one-dimensional hydrodynamic (HD) equations of the slim disks in the presence of the wind and in cylindrical coordinates using self-similar solution. We considered power-law function of for mass loss rate due to wind. Then, we considered mass loss, angular-momentum loss and energy loss in equations. Then, we treated the influence of wind on the dynamics of the system. As an agreement ...

‎Consider an estimation problem in a one-parameter non-regular distribution when both endpoints of the support depend on a single parameter‎. ‎In this paper‎, ‎we give sufficient conditions for a generalized Bayes estimator of a parametric function to be admissible‎. ‎Some examples are given‎. ‎
