the need for intercultural awareness and skills emerges strongly in both distance learning courses, and in social life in multicultural societies. the study of online language transactions is therefore an important aspect of the emerging culture and sociolinguistics of computer mediated communication. the research reported in this paper concerns perceptions held by students in an iranian univer...

with the advent of e-commerce, organizations are changingtheir business. most researchers believe that electronic trading can besuccessful when the public will trust in virtual environments. high degreeof confidence not only can meet customer expectations of a satisfactorytransaction, but can also eliminate certainty and perceived risk of onlinetransactions. the aim of this research is to study...

in biaxially strained p-mosfet with si channel, formation of a parasitic parallel channel due to misalignment of energy bands degrades device performance by increasing off-state current. in this paper a new approach has been introduced to eliminate this parasitic channel by increasing the dopant concentration of virtual substrate up to . using simulation the impact of this method on the parasit...

this paper proposes improvements and revisions to a recent approach in a voting system, and provides an effective approach with a stronger discriminate power. for this purpose, the advantage of a linear transformation is utilized to redene a previously used concept of virtual worst candidate, by incorporating the existing weight restrictions. then, the best score of this virtual candidate is u...

this study has been conducted to examine the impact of the increasing use of virtual social networks on family structure. to achieve more accurate results, the research is carried out using the mixed method (qualitative and quantitative) and to collect the required date, first, 30 married individuals active in virtual social networks were selected and interviewed. then, a questionnaire was util...

lack of trust is one of the key bottle necks in e-commerce development. nowadays many advanced technologies are trying to address the trust issues in e-commerce. one among them suggests using suitable user interfaces. this paper investigates the functionality and capabilities of 3d graphical user interfaces in regard to trust building in the customers of next generation of b2c e-commerce websit...

the concept of virtual water trade refers to transact of the water consumed for production of goods and agricultural products through international trade. the anthony allan introduced this concept to improve global water used efficiency. in this paper, the original theory of allen has been investigated through incorporating virtual water as a factor of production in heckscher-ohlin internationa...

Gilles Deleuze has become a key reference for the recent debate on virtual technologies, as his conception of is widely used to argue reality virtuality. Nonetheless some scholars, among which Slavoj Žižek stands out, have warned about risks flattening Deleuzian concept tech debate. This paper aims show why two concepts do not overlap by explaining features that make it incompatible with media....

This paper proposes the virtual flux based direct power control for Vienna rectifier. No need for the input voltage sensors, the current regulation loop and PWM voltage modulation block along with the active and reactive power decoupling are some of the salient advantages of this method that make it suitable for controlling the conventional active rectifiers. However, due to the three-level nat...

-  Power system state estimation is a central component in energy management systems of power system. The goal of state estimation is to determine the system status and power flow of transmission lines. This paper presents an advanced state estimation algorithm based on weighted least square (WLS) criteria by introducing virtual meters. For each bus of network, except slack bus, a virtual meter...
