Nicotine aff ects hydrogen sulfi de concentrations in mouse kidney and heart but notin brain and liver tissues

Jerzy Wiliński, Bogdan Wiliński, Eugeniusz Somogyi, Joanna Piotrowska, Tomasz Kameczura & Zygmunt
Nicotine, a potent parasympathomimetic alkaloid with stimulant effects, is contributing to addictive properties of tobacco smoking and is though used in the smoking cessation therapy. Hydrogen sulfide (H2S) is involved in physiology and pathophysiology of various systems in mammals. The interactions between nicotine and H2S are not fully recognized. The aim of the study is to assess the influence of nicotine on the H2S tissue concentrations in different mouse organs. Adult CBA male mice were...

Generalized utilization-based similarity coefficient for machine-part grouping problem in cellular manufacturing

Tamal Ghosh
This article intends to justify the gap in the research of similarity coefficient driven approaches and cell formation problems (CFP) based on ratio data in cellular manufacturing systems (CMS). The actual implication of ratio data was vaguely addressed in past literature, which has been corrected recently. This research considered that newly projected CFP based on ration data. This study further revealed the lack of interest of researchers in investigation for an appropriate and improved similarity...

A web-based electronic data interchange as supplier and assembly interface

Rika Yunitarini, Pratikto Pratikto, Purnomo Budi Santoso & Sugiono Santoso
In the assembly industry, almost all components are outsourced or transferred to other parties, in order to meet the need for supply. This is referred as outsourcing of production. The outsourcing of assembly product components is based on a relationship model between the contractor and the industry. However, there is no relationship or communication pattern between the contractor or supplier and the assembler. Hence, in order to accelerate line production and overcome problems with assembly...

Exploring heuristic techniques for flow shop scheduling

Zuzana Soltysova, Pavol Semanco & Jan Modrak
This paper explores selected heuristics methods, namely CDS, Palmer’s slope index, Gupta’s algorithm, and concurrent heuristic algorithm for minimizing the makespan in permutation flow shop scheduling problem. Its main scope is to explore how different instances sizes impact on performance variability. The computational experiment includes 12 of available benchmark data sets of 10 problems proposed by Taillard. The results are computed and presented in the form of relative percentage deviation, while outputs of the NEH...

Development and application of a decision making tool for fault diagnosis of turbocompressor basedon Bayesian network and fault tree

Abdelaziz Lakehal, Mourad Nahal & Riad Harouz
Fault Tree is one of the traditional and conventional approaches used in fault diagnosis. By identifying combinations of faults in a logical framework it’s possible to define the structure of the fault tree. The same go with Bayesian networks, but the difference of these probabilistic tools is in their ability to reasoning under uncertainty. Some typical constraints to the fault diagnosis have been eliminated by the conversion to a Bayesian network. This paper shows that...

Application of instance-based learning for cast iron casting defects prediction

Robert Sika, Damian Szajewski, Jakub Hajkowski & Paweł Popielarski
The paper presents an example of Instance-Based Learning using a supervised classification method of predicting selected ductile cast iron castings defects. The test used the algorithm of k-nearest neighbours, which was implemented in the authors’ computer application. To ensure its proper work it is necessary to have historical data of casting parameter values registered during casting processes in a foundry (mould sand, pouring process, chemical composition) as well as the percentage share of defective castings...

Demand driven material requirements planning. Some methodical and practical comments

Miriam Pekarcıkova, Peter Trebuna, Marek Kliment & Jozef Trojan
Industry 4.0 will affect the complexity of supply chain networks. It will be necessary to adapt more and more to the customer and respond within a time interval that is willing to accept the product waiting. From these considerations, there is a need for a different way of managing the supply chain. The traditional concept of supply chain as a linear system, which allows optimizing individual subsystems, thus obtaining an optimized supply chain, is not...

Fuzzy modeling and parametric analysis of non-traditional machining processes

Shankar Chakraborty & Partha Protim Das
The application of artificial intelligence (AI) in modeling of various machining processes has been the topic of immense interest among the researchers since several years. In this direction, the principle of fuzzy logic, a paradigm of AI technique, is effectively being utilized to predict various performance measures (responses) and control the parametric settings of those machining processes. This paper presents the application of fuzzy logic to model two non-traditional machining (NTM) processes, i.e. electrical discharge...

Minimizing length in a mixed model two sided assembly line using exact search method

Ashish Yadav, Pawan Verma & Sunil Agrawal
In the two-sided mixed-model assembly line, there is a process of installing two single stations in each position left and right of the assembly line with the combining of the product model. The main aim of this paper is to develop a new mathematical model for the mixed model two-sided assembly line balancing (MTALB) generally occurs in plants producing large-sized high-volume products such as buses or trucks. According to the literature review, authors focus on...

Entrepreneurial leadership in SMEs: perceptions of owner – managers vs. employees

Gelmar Garcıa-Vidal, Alexander Sanchez-Rodrıguez, Reyner Perez-Campdesuner & Rodobaldo Martınez-Vivar
The objective of this research is to investigate the perception of owner – managers and their employees regarding entrepreneurial leadership. To develop the research, two questions are raised related to the similarities or differences of the perceptions of both groups with what is established in the literature and between the self – evaluation of the owner – managers and their employees on whether the former perform as an entrepreneurial leader. As a research method, both...

Planning and scheduling of production system in conditioning line: industrial application, optimizationand simulation approach

Zineb Ibn Majdoub Hassani, Abdellah El Barkany, Ikram El Abbassi, Abdelouahhab Jabri & Abdel Moumen Darcherif
In this article we present an industrial application of our mathematical model that integrates planning and scheduling. Our main objective is to concretize our model and compare the reel results with the theoretical ones. Our application is realized on a conditioning line of pharmaceutical products at the ECAM EPMI production laboratory. For this reason and to save time, we used Witness simulation tool. It gives an overall idea of how the line works, the Makespan...

An analysis of the operating parameters of the vacuum furnace with regard to the requirementsof predictive maintenance

Sławomir Kłos, Władysław Papacz & Łukasz Piechowicz
The Industry 4.0 Concept assumes that the majority of industry’s resources will be able to self-diagnose; this will, therefore, enable predictive maintenance. Numerically controlled machines and devices involved in technological processes should, especially, have the facility to predict breakdown. In the paper, the concept of a predictive maintenance system for a vacuum furnace is presented. The predictive maintenance system is based on analysis of the operating parameters of the system and on the algorithms for...
