This paper proposes a model for studying the computation of xpoints that arise in complex program analysis based on abstract interpretation, and presents an e cient algorithm for computing xpoints based on the model. Abstract interpretation provides a uni ed framework for handling interprocedural analysis of programs with unrestricted pointer manipulation, higher-order functions, and continuati...

Background Outdoor work is associated with high and chronic exposure to solar ultraviolet radiation which might lead an increased risk of developing skin (pre)malignancies. Prevalence actinic keratosis (AK), basal cell carcinoma (BCC), cutaneous squamous (cSCC) melanoma (cM) in Dutch outdoor workers (OW) has not previously been investigated. Objective This study compares the prevalence premalig...

This study has been inspired by the paper "An efficient 3D topology optimization code written in MATLAB” written by Liu and Tovar (2014) demonstrating that SIMP-based three-dimensional (3D) topology optimization of continuum structures can be implemented in 169 lines of MATLAB code. Based on the above paper, we show here that, by simple and easy-to-understand modificati...

In this paper we identify the common building blocks that enable some networks to provide better than best-eeort transfer guarantees to the traac they carry. We consider the role signaling plays in such a network and argue in favor of: pinned routes, with a highly eecient pinning process, to improve network stability and to ease the task of maintaining Quality of Service (QoS) guarantees in the...

Generation of steady-state solid aerosol jets with controllable parameters is often necessary in experimental studies and industrial processes.Most of the current approaches use a  uidizedbed to produce an aerosol  owandalways introduce initial turbulence into the jet. Toproduce a laminar aerosol jet,  ow straighteners and long tubes are used that make the design cumbersome and in exible. I...

Activated water irrigation has been widely investigated as an effective production increasing measure. However, the response of activated in plant growth and use efficiency (WUE) with amount is not well understood. Here, a pot experiment was conducted to determine effects on winter wheat growth, yield, WUE under amount. Twelve treatments included four types, (i) tap (TW), (ii) magnetization (MW...

it is known that a stochastic dierential equation (sde) induces two probabilisticobjects, namely a diusion process and a stochastic ow. while the diusion process isdetermined by the innitesimal mean and variance given by the coecients of the sde,this is not the case for the stochastic ow induced by the sde. in order to characterize thestochastic ow uniquely the innitesimal covariance give...

fifty-four specimens of the kingsoldier bream, argyrops spinifer (forsskal, 1775) from coastal waters of the persian gulf, in bushehr province, were aged by otolith readings to assess the suitability of using otolith length/weight for age estimation in this fish. otolith length and weight increased along with an increase in length and age of the fish. the relationship between fish length (tl) a...

background: aflatoxins (afs) are the most prevalent carcinogenic mycotoxins, produced mainly by aspergillus flavus and a. parasiticus. the general purpose of the present study was to use dehydroacetic acid (dha) and ozonated water (ow) to control a. flavus growth and accumulation of aflatoxin b1 (afb1) in iranian pistachios. methods: three treatment pistachio groups were separately immersed in ...

An extension of the Disjunctive Model, eeciently representing Jobshop Scheduling (JS) problem, to more general Resource-Constrained Project Scheduling (RCPS) problem is proposed. The extension considers diierent groups of resources used by activities in diierent amounts limited to a constant value in every moment of the project duration. A solution to the problem is represented by a project res...
