Objectives: This research aims to sneak into the retailer\'s perception about that customer segment and plan a product mix accordingly. The focus is on small players in towns not having deep pockets synergize decisions effectively. Methods: data used this paper from Hatchers, medium-sized enterprise with zero budget for software decisions. was collected through face-to-face interviews ten repre...
One of the main problems of car-like robot is robust path following in the presence of sliding effect. To tackle this problem, a robust mix H2/H∞ static state feedback control method is selected. This method is the well-known linear robust controller which is robust against external disturbance as well as model uncertainty. In this paper, the path following problem is formulated as linear matri...
A planning procedure to set the constant level of work in process (WIP) for each product type in a job shop operated under CONWIP control is developed. We model the job shop as a single chain multiple class closed queuing network. Given a specified product mix and a total WIP, a nonlinear program bounds the throughput of the network and optimizes the WIP mix. We identify the minimum total WIP t...
background: the prevalence of allergic diseases has risen in the last decades. the objective of this study was to determine the common allergens in children via the skin prick test. methods: this cross-sectional study recruited 313 allergic children (4 months to 18 years old) referred to the asthma and allergy clinic of children’s medical center in tehran. a questionnaire containing demographic...
abstract this thesis includes five chapter : the first chapter assign to establish fuzzy mathematics requirement and introduction of liner programming in thesis. the second chapter we introduce a multilevel linear programming problems. the third chapter we proposed interactive fuzzy programming which consists of two phases , the study termination conditions of algorithm we show a satisfac...
This paper addresses the security and efficiency issues of the Mix-net based on permutation networks introduced in [1]. We first show that the original construction results in a Mix-net that yields biased permutation, so it gives some advantage to adversaries. A simple repair is provided. We then observe that one of the original schemes can be improved so that the servers and verifier enjoy mor...
We present the architecture, design issues and functions of a MIX-based system for anonymous and unobservable real-time Internet access. This system prevents tra c analysis as well as ooding attacks. The core technologies include an adaptive, anonymous, time/volumesliced channel mechanism and a ticket-based authentication mechanism. The system also provides an interface to inform anonymous user...
