This paper describes a mechanism allowing nodes to hand-off active connections by utilizing connection splicing at an edge-switch serving as a gateway to a server cluster. The mechanism is primarily intended to be used as part of a content aware request distribution strategy. Our approach uses an extended form of network address translation which maps inbound connection information (ie. address...

This letter proposes a novel pneumatic soft robotic hand that incorporates mechanism can switch the airflow path using single control. The developed control finger motion and operate surface friction variable mechanism. In mechanism, lubricant is injected onto high-friction to reduce friction. To inject lubrication positive-pressure airflow, Venturi effect applied. design evaluation of airflow-...

our aim in this paper is to introduce the notion of fuzzy soft near-subtraction semigroupsand fuzzy soft ideals of near-subtraction semigroups. we discuss some important properties of these new fuzzy algebraic structure and investigate some examples and counter examples.

Although a typical PWM controller is well known for its good regulation capabilities, inrush current and overshoot voltage during start-up period as well as high switching losses at low loads are some of the major factors affecting its otherwise good performance. Therefore in this paper a simple Soft-start pulse skipping modulation (SSPSM) scheme implemented on a typical buck converter is prese...

Photovoltaic power generation system implements an effective utilization of solar energy, but generally has very low conversion efficiency. Maximum power point tracking (MPPT) is used in photovoltaic (PV) systems to maximize the photovoltaic array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics. A MPPT system has been developed...

The propensity of stem cells to specify and commit to a particular lineage program is guided by dynamic biophysical and biochemical signals that are temporally regulated. However, most in vitro studies rely on "snapshots" of cell state under static conditions. Here we asked whether changing the biophysical aspects of the substrate could modulate the degree of mesenchymal stem cell (MSC) lineage...

■ User Adjustable Slope Compensation The LT1680 is a high power, current mode switching power supply controller optimized for boost topologies. The IC drives an N-channel MOSFET switch for DC/DC converter applications up to 60V input. A high current gate drive output handles up to 10,000pF gate capacitance, enabling the construction of high power DC/DC converters. Current sense common mode rang...

Acute leukemia which is the most common cancer in children is a heterogeneous group of clonal malignancies. The conversion of the leukemic cell lineage during the course of the disease or later is termed lineage switch. It has been rarely reported in the literature. In leukemia lineage switch, conversions from lymphoblastic leukemia to myeloid leukemia or vice versa are reported. Herein, we rep...

The performance of bit-interleaved coded modulation in multiple-input multiple-output (BICM-MIMO) systems using an iterative channel estimator is analysed. In a conventional iterative channel estimator, after initialisation with the training phase, the channel estimator switches to the data phase. However, such a conventional iterative channel estimator does not always improve the performance o...

Signal integrity and packet data protection against soft errors represent highly relevant challenges for Networks-on-Chip regarding the shrinking of process technology. Therefore, data protection and error recovery strategies at the End-to-End level are the most convenient solutions considering overall implementation costs and performance penalties. Nevertheless, protection of packet header con...
