We believe that enterprises and other organisations currently lack sophisticated methods and tools to determine if and how IT changes should be introduced in an organisation, such that objective, measurable goals are met. This is especially true when dealing with security-related IT decisions. We report on a feasibility study, Trust Economics, conducted to demonstrate that such methodology can ...

We study a colourful generalization of the linear programming feasibility problem, comparing the algorithms introduced by Bárány and Onn with new methods. This is a challenging problem on the borderline of tractability, its complexity is an open question. We perform benchmarking on generic and ill-conditioned problems, as well as recently introduced highly structured problems. We show that some...

In this paper we consider a new type of mixed integer programming problem: Transportation Network with Supply Eating Arcs. This problem arises from an application in intelligent telecommunications] networks, IN. It contains within its deenition many classical mixed integer programming problems. The problem is deened as a transportation network with an additional condition. For an arc to have po...

In this paper we consider the NP-hard problem of finding a feasible solution (if any exists) for a generic MIP problem of the form min{cT x : Ax ≥ b, xj integer ∀j ∈ I}. Trivially, a feasible solution can be defined as a point x∗ ∈ P := {x : Ax ≥ b} that is equal to its rounding x̃, where the rounded point x̃ is defined by x̃j := [xj ] if j ∈ I and x̃j := xj otherwise, and [·] represents scalar rou...

an aquifer located within a petroleum processing plant in moín, costa rica, suffers hydrocarbon pollution. this study aimed to determine the ability of indigenous microorganisms from this site to degrade polycyclic aromatic hydrocarbons (pahs) to evaluate the feasibility of an eventual bioremediation process. aerobic conditions were found in the aquifer, while microbial analyses of the groundw...

Pilot and feasibility studies underpin much of current health related research, including randomised controlled trials. The number of reports in which authors describe their studies as pilot or feasibility studies is increasing. In spite of recent attempts to define pilot and feasibility studies, the research community has differing views about these definitions. We will present a framework for...

OBJECTIVE The purpose of this pilot study was to determine the scientific and process feasibility in an effort to direct future larger trials. METHODS Scientific Feasibility: Twelve subjects were randomly allocated to an intervention and a control group. The intervention protocol consisted of intraoral vibration therapy on the muscles of mastication bilaterally for a period of 1 minute per mu...

The waste of agricultural products is considered as one of the major problems in Iranian agricultural sector. The present study is a descriptive-survey one in nature that focused on exploring correlations and comparison. Data were collected through a number of questionnaires and were analyzed by SPSS. The relationships between dependent and independent variables were analyzed by obtaining the P...
