Reconsideration of mass-distribution models

States, Models and Information: a Reconsideration of Ellsbergs Paradox

We show that a general process of decision making involves uncertainty about two di¤erent sets: the domain of the acts and another set, which we call the set of models for the decision maker. We study the e¤ect of di¤erent information structures on the set of models, and prove the existence of a dichotomy: either the decision maker’s ranking of the acts obeys Subjective Expected Utility theory ...

Relativistic Electromagnetic Mass Models: Charged Dust Distribution in Higher Dimensions

Electromagnetic mass models are proved to exist in higher dimensional theory of general relativity corresponding to charged dust distribution. Along with the general proof a specific example is also sited as a supporting candidate. PACS number(s): 04.20.-q, 04.40.Nr, 04.20.Jb

A Reconsideration of Tolerance:

A Reconsideration of Preconditions

This paper is part of an attempt to introduce intentionality of the actor to planning decisions. As a first step in this process the usual representations for actions used by planning systems must be reevaluated. this paper argues for the elimination of preconditions and qualification conditions from action representation in favor of explicit representation of intention, situated reasoning abou...

Reconsideration of Laparoscopic Cholecystectomy

We describe the surgical method of cases showing a distended gallbladder. Because the most important thing does not cause biliary tract injury, it is to find orientation carefully. The frequency of incidental gallbladder cancer was in 7 (0.7%) of the 983. Only cholecystectomy is necessary to be performed for Tis or T1 cancer, and surgery has to be changed to radical surgery for T2 cancer or dee...
