The UK, with its relatively liberal immigration policies following recent enlargements, has been one of the main recipients of migrants from new EU member states. This paper poses the questions: what is the effect of immigration on a receiving economy such as the UK? Is the effect beneficial or adverse for growth? How differently would skilled (or unskilled) migration affect both receiving and ...

In the data communication, the intriguing issue to provide data security and these led to comprise the many areas including the impregnable medium and trusted third party to maintain a database and various types of encryption techniques. These are main inducement of researchers in this area to protect the data from unauthorized users for malicious purpose. Therefore there are requires the diffe...

In order to exploit the inherent parallelism in distributed systems through object-oriented programming a Distributed Parallel Object Manager for Smalltalk is implemented. In the previous Distributed Smalltalk implementations, the remote operational model is used where the sending process blocks, the receiver process performs the operation, a value is returned, and the sending process then resu...

In low-power and lossy networks (LLNs), power-constrained devices consume most of power to communicate with their neighbors. To save power, traditional MAC protocols usually turn off RF transceivers while there is no radio communication. Since RF transceivers consume most of their energy in idle listening, turning RF transceivers off can save significant amount of energy. However, delay of pack...

Ultrasonic, used in security technology such as car collision avoidance and distance measurement, also can be used in detecting obstruction behind the car when backing up. In this paper, we analyze the interference of ultrasonic signal when transmitting and receiving, and then resolve it by software. There is a blind area and distance limitation in ultrasonic distance measurement .The cause of ...

1 KAFLE et al. IIPP: Integrated IP paging protocol with a power save mechanism SUMMARY The advent of advanced mobile/wireless systems has been facilitating the battery-powered mobile computing devices (nodes) to remain always-connected to the Internet. However, until now, the power-drain rate of mobile nodes is very high in comparison with the available power of portable batteries. To reduce th...

Wireless Sensor Network technology is a wireless network consisting of several individual sensor nodes that are used to monitor the condition place and can interact with its environment by means sensing, controlling communication physical parameters. The application Technology water turbine as power plant for remote control monitoring turbine. So it allows users get maximum real time informatio...

Long-distance high voltage alternating current (AC) submarine cables are widely used to connect offshore wind farms and land power grids. However, the transmission capacity of cable is limited by capacitive charging current. This paper analyzes impacts reactive compensation in different positions on distribution long-distance lines, tests rationality existing schemes based electrothermal coordi...

Power swing is a power system transient phenomenon that arises due to several reasons including line switching, outage, sudden increment or decrement in load, faults, etc. Unnecessary tripping during and unnecessary blocking for faults occur result distance relay maloperation. Several cascaded outages major worldwide blackouts have occurred maloperation of relays. This paper proposes technique ...
