Sustainable tourism and ecotourism have now been researched in depth for some years. This paper highlights that researchers still have only a limited understanding of what tourist behaviour can be considered as sustainable, and little consensus about who environment-friendly tourists (EFTs) actually are. This study reviews theoretical and empirical studies by tourism researchers, and explores w...

NS2 is a discrete event simulator targeted at networking research. NS2 provides substantial support for simulation of routing protocols over wired and wireless (local and satellite) networks. NS2 uses TCL script for its front end and C++ as its back end [1,5]. NS2 is completely command based and one needs to create a TCL file for running any network simulation. Therefore, it’s very tedious for ...

EPOC (Efficient Probabilistic Public-Key Encryption) is one of the public-key cryptosystems. It was proposed by Tatsuaki Okamoto, Shigenori Uchiyama, and Eiichiro Fujisaki in NTT in 1998 [4, 6, 7]. EPOC has three versions. In order to provide an easy and convenient graphical user interface, we implemented a GUI of EPOC3 then combined with previously PSEC-KEM and ECDSA on Windows. Through the us...

Natural Language Generation (NLG) systems can make data accessible in an easily digestible textual form; but using such systems requires sophisticated linguistic and sometimes even programming knowledge. We have designed and implemented an environment for creating and modifying NLG templates that requires no programming knowledge, and can operate with a minimum of linguistic knowledge. It allow...

INTRODUCTION Population aging is a worldwide phenomenon. As a response, the World Health Organization (WHO) introduced the concept of 'age-friendliness' in 2006. Age-friendliness is defined in terms of a range of domains, such as housing, opportunities for participation, and transportation. Communities that accommodate the needs of older adults in these domains will, it is thought, promote heal...

Plants in urban areas play an essential role to cleanse the pollution in human environment. The paper describes the choice of eco–friendly plant species and their right placement in the urban environment to overcome the pollution problems.

Based on two PhD studies on gender recruitment at an engineering univeristy in Denmark, this paper discusses whether and how a PBL environment have been functioning in the recruitment of engineering students. The research findings from both studies show that the PBL environment can be regarded as a learning environment that is friendly to students of both genders. However, it did not witness dr...

During the high-temperature construction of hot mix asphalt mixture, a large number harmful emissions such as smoke are produced, which seriously endangers workers’ health and pollutes surrounding environment. The object this study is to reduce emission improve Tourmaline (T), graphene oxide (GO), KH 550 silane coupling agent (K) were used prepare GO/KT-modified influence modifier content on ba...
