this paper addresses a production and outbound distribution scheduling problem in which a set of jobs have to be process on a single machine for delivery to customers or to other machines for further processing. we assume that there is a sufficient number of vehicles and the delivery costs is independent of batch size but it is dependent on each trip. in this paper, we present an artificial imm...

Introduction: One of the most valuable goals of phantoms, replacing with human goals in the field of research and quality control of diagnostic X-ray systems. There are various algorithms and methods for obtaining Homogeneity and CT number linearity for CT scan device. One of the most famous of these methods, the method is to use a uniform and homogeneous environment to comput...

The Turing degree of a real number is defined as the Turing degree of its binary expansion. In this note we apply the double witnesses technique recently developed by Downey, Wu and Zheng [2] and show that there exists a ∆2-Turing degree which contains no divergence bounded computable real numbers. This extends the result of [2] that not every ∆2-Turing degree contains a d-c.e. real.

mechanical weeding is one of the non-chemical methods to control weeds. in this paper a ‎new mechanism has been presented for mechanical cultivation. the machine works based on ‎the manual tools operation, which farmers still use in small scale for weeding and consists of a ‎number of four-bar linkage mechanisms. each mechanism consists of a blade which moves ‎forward (active course) and backwa...

Recent advances in predictive data analytics and ever growing digitalization and connectivity with explosive expansions in industrial and consumer Internet-of-Things (IoT) has raised significant concerns about security of people’s identities and data. It has created close to ideal environment for adversaries in terms of the amount of data that could be used for modeling and also greater accessi...

the colorado beetle, leptinotarsa decemlineata (say), is the major defoliating and exotic insect pest of potato plants and has caused serious problems in the east azerbaijan and ardabil regions of iran since emerging in the absence of natural native enemies. in the development of a suitable control strategy based on integrated pest management, it is important to recognize control methods that d...

The types of mobile robot can be roughly divided into three categories, wheeled type, crawler type and legged type. In these types, walking machine (legged type robot) has some of noteworthy strong points that other types of mobile robot don't have. Especially, high adaptability to the terrain is one of the most important strong points of walking machine. The fact that general type of walking m...

In this paper we consider the problem of universal prediction of individual continuous sequences with square-error loss, using a deterministic finite-state machine (FSM). The goal is to attain universally the performance of the best constant predictor tuned to the sequence, which predicts the empirical mean and incurs the empirical variance as the loss. The paper analyzes the tradeoff between t...
