Marketing policies and strategies have long term effects on firm’s financial indicators. Measuring these long term effects is somehow difficult and it could be important from managers’ viewpoint as well. Up to now a lot of researches have been done to disclose these effects but the previous studies have limitation in demonstration of these long-term ...

In this paper, the authors explain based on using MikroTik router Operating System (OS) to build an authentication and billing System. This kind of system is always used to create security, billing and administration of users on a network connected to the internet. It is used to restrict usage and bandwidth allocations to users. A ...

The operation of core router is to restrict network broadcast to the LAN, to act as default gateway, to move data between different networks and to advertise loop free path. The technology of Wi-Fi, Worldwide interoperability for Microwave Access (WiMAX), General Packet Radio Services (GPRS), Enhanced Data rates for GSM Evolution (EDGE), EVolution Data Optimized ...

With CMOS scaling down, to maintain integration suitability current mode devices are finding more consideration in circuit designs. The paper propose a modified high frequency current controlled current conveyor CMOS circuit CCCII where current gain, current controlling intrinsic impedance and circuit offsets are programmable independently to desired values within a specific field range after fabrication ...
