A discrete-time communication framework is studied under an approximate socalled "stop protocol" related to the lost-calls-held protocol. An explicit insensitive product form expression as recently obtained under a less realistic recirculated protocol is shown to remain valid. This extension seems of both practical and theoretical interest. Applications include: • Circuit switching structures •...

Circuit-switched Banyan interconnection networks can be built from simple switching elements that do not have logical processing or buffering capabilities. This paper describes a distributed technique for dynamic control of such a network, so that circuits can be established in response to the changing needs of a parallel application. Control information is interleaved with data, thus avoiding ...

Many multipoint virtual circuit switching systems have been proposed for use in ATM networks. The inherent exibility of ATM networks and the desire to use them for a wide range of diierent applications makes it impractical to rely upon statistical traac models, motivating a renewed interest in nonblocking networks. While the various multipoint architectures can all be conngured to be nonblockin...

Control of droplets in microfluidic environments has numerous applications ranging from analysis and sample preparation for biomaterials synthesis (Mann and Ozin 1996) and medical diagnostics (Pipper et al. 2007) to photonics (Schmidt and Hawkins 2011). Here we study the oscillations present in a microfluidic circuit capable of sorting curable droplets on demand by triggering the circuit with U...

This thesis presents High frequency Soft Switching DC-DC boost Converter. The circuit consists of a general Boost Converter with an additional resonant circuit which has a switch, inductor, capacitor and a diode.In general Boost Converter circuits have snubber circuits where switching losses are dissipated in external passive resistors; which is known as hard switching. As the switching frequen...

Battery equalization can increase batteries’ life cycle, utilization, and reliability. Compared with battery equalization topologies based on resistance or energy storage components, the topologies based on transformers have the advantages of high balancing current and efficiency. However, the existence of switching losses will reduce the reliability and service life span of the equalization ci...

Network-on-Chip (NoC) architectures represent a promising design paradigm to cope with increasing communication requirements in digital systems. Network-on-chip (NoC) has emerged as a vital factor that determines the performance and power consumption of many-core systems. A novel switching mechanism, called virtual circuit switching, is implemented with circuit switching and packet switching. A...

Conventional charge pump circuits use a fixed switching frequency that leads to power efficiency degradation for loading less than the rated loading. This paper proposes a level shifter design that also functions as a frequency converter to automatically vary the switching frequency of a dual charge pump circuit according to the loading. The switching frequency is designed to be 25 kHz with 12 ...

More and more complex and larger system on chips are getting developed as a result of increase in chip density following Moore’s law. Advanced SoCs have in their shelf significantly noticeable communication mechanisms. NoC has solved the scalability problems to a larger extent compared to bus based interconnect. NoC has been providing a back bone infrastructure for System-on-chips since long. A...

In this paper a novel Interleaved Boost Converter (IBC) with soft-switching techniques is proposed. Through the zero-voltage switching (ZVS) and zero-current switching (ZCS) reduces the current stress of the main circuit components, in addition to this it can also reduces the ripple of the input current and output voltage. In this approach, it can be faster switching, reduce the size and cost w...
