The stimuli acting upon the choice of shelter and resting place by the house cricket, Acheta domesticus (L.) were analysed. The places of preference in different types of terraria as well as the choice of tubes of different diameter and of various light conditions were investigated. Acheta domesticus avoids open and illuminated space in its choice of resting place. It prefers dark places, enclo...

Introduction Dengue fever is an important vector-transmitted disease that affects more than 100 countries worldwide. Locations where individuals tend to gather may play an important role in disease transmission in the presence of the vector. By controlling mosquitoes' breeding places, this study aims to analyze the effect of reducing transmission in elementary schools (grades 1-9) on the dynami...

Finding all minimal bad siphons is essential for deadlock control. However, the number of siphons grows exponentially with the size of the system. Deadlock occurs due to inappropriate resource sharing. Hence most research focused on the problem of minimal siphon extraction covering a set of places representing resources — an NP-Complete problem for arbitrary Petri Nets. We develop the theory fo...

Recently, there have been several studies about personal music recommendation system on the internet and personal computer environment, but the music recommendation system for public places has not been studied. In this paper, we study a music recommendation system based on a sensor network in public places such as highway rest places, parks, huge marts, etc. The proposed system includes five m...

The theory of Petri nets that was conceived to model the interactions between asynchronous concurrent processes, can be extended to explore conflicts and delineate the options available to resolve such conflicts in such processes. To this end we define the property of essentially decision free places (EDF places) in Petri nets to represent the absence of conflicts in resource allocations. Using...
