Abstract This study aims to determine the characteristics of sediments found in Jeneberang River specifically upstream part. The data required includes results sieve analysis, grain diameter sediment and density sediment. was conducted by taking samples from segments around Sabo 7-1. obtained indicate that gradation particles consists fine sand, medium coarse gravel with a median (D50) 0.5-13.1...

This study compares 3D dose distributions obtained with voxel S values (VSVs) for soft tissue, calculated by several methods at their current state-of-the-art, varying the degree of image blurring. The methods were: 1) convolution of Dose Point Kernel (DPK) for water, using a scaling factor method; 2) an analytical model (AM), fitting the deposited energy as a function of the source-target dist...

AIMS To establish whether there is a difference in recovery of salivary function with bilateral superficial lobe parotid-sparing intensity-modulated radiotherapy (BSLPS-IMRT) versus contralateral parotid-sparing IMRT (CLPS-IMRT) in patients with locally advanced head and neck squamous cell cancers. MATERIALS AND METHODS A dosimetric analysis was carried out on data from two studies in which p...

The general restrictions on all economic primitives (i.e., (a) endowments, (b) preferences, and (c) asset return distributions) that yield the CAPM under the expected utility paradigm are provided. These results are then used to derive the class of restrictions on preferences and the distribution of asset returns alone that provides the CAPM. We also show that the conditions that provide the CA...

We survey the literature devoted to the study of the problem of allocating an infinitely divisible commodity among agents whose preferences are single-peaked. We formulate a number of normative and strategic requirements on rules, and study their implications when imposed in various combinations. A unique rule emerges as being the best-behaved from a variety of viewpoints: the uniform rule. Key...

We decentralize incentive efficient allocations in large adverse selection economies by introducing a Walrasian market for mechanisms, that is, for menus of contracts. Facing a budget constraint, informed individuals choose lotteries over mechanisms, while firms supply (slots at) mechanisms at given prices. An equilibrium requires that firms cannot favorably change, or cut, prices. We show that...

This contribution deals with the fundamental critique in Dinar et al. (1992, Theory and Decision 32) on the use of Game theory in water management: People are reluctant to monetary transfers unrelated to water prices and game theoretic solutions impose a computational burden. For the bilateral alternating-o¤ers model, a single optimization program signi…cantly reduces the computational burden. ...

In this paper, we extend the non-cooperative analysis of oligopoly to exchange economies with infinitely many commodities by using strategic market games. This setting can be interpreted as a model of oligopoly with differentiated commodities by using the Hotelling line. We prove the existence of an “active” Cournot-Nash equilibrium and show that, when traders are replicated, the price vector a...

This study develops a theoretical general equilibrium model to examine optimal externality tax policy in the presence of externalities linked to one another through markets rather than technical production relationships. Analytical results reveal that the second-best externality tax rate may be greater or less than the first-best rate, depending largely on the elasticity of substitution between...
