in vehicular ad hoc networks there is the ability to communicate between vehicles. this communication which is wireless should be rapid and reliable. these networks have unique characteristic. this communication among vehicles has many advantages in safety and comfort applications. since, the roads are always encountered to accidents and risks, using optimized tools could be useful in these sit...

carbon nanotubes (cnts) are high aspect ratio allotropes of carbon. because of their unique physical and chemical characteristics, they are nominated for a vast variety of applications in the biomedical field. their very low solubility is the only problem of them which is solved by different methods of functionalization. after discoveries in the last few years of the capacity of cnts to penetra...

Group communication will undoubtedly be a useful paradigm for many applications of wireless networking in which reliability and timeliness are requirements. Moreover, locationawareness is clearly central to mobile applications such as traÆc management and smart spaces. In this paper, we introduce our de nition of proximity groups in which group membership depends on location and then discuss so...

Proper design has become a critical element needed to engage website and mobile application users. However, little research has been conducted to define the specific elements used in effective website and mobile application design. We attempt to review and consolidate research on effective design and to define a short list of elements frequently used in research. The design elements mentioned m...

This paper presents MISTRAL+, a dedicated tool for the study of under-resourced languages. MISTRAL+ is the upgrated version of an automatic tool created in 2004 called MELISM. The entire process has been modified in order to simplify and enhance the study of under-resourced languages. MISTRAL+ is composed of two separated modules: MISTRAL_Praat a plugin integrated to the tool PRAAT, and MISTRAL...
