An adaptive extension library for improving collective communication operations
Authors: Hartmann O. , Kühnemann M. , Rauber T. , Rünger G. 
Published: September 2007

AbstractIn this paper, we present an adaptive extension library that combines the advantage of using a portable MPI library with the ability to optimize the performance of specific collective communication operations. The extension library is built on top of MPI and can be used with any MPI library. Using the extension library, performance improvements can be achieved by an orthogonal organization of the processors in 2D or 3D meshes and by decomposing the collective communication operations into several consecutive phases of MPI communication. Additional point‐to‐point‐based algorithms are also provided. The extension library works in two steps, an a priori configuration phase detecting possible improvements for implementing collective communication for the MPI library used and an execution phase selecting a better implementation during execution time. This allows an adaptation of the performance of MPI programs to a specific execution platform and communication situation. The experimental evaluation shows that significant performance improvements can be obtained for different MPI libraries by using the library extension for collective MPI communication operations in isolation as well as in the context of application programs.

Design equations for fractional‐order sinusoidal oscillators: Four practical circuit examples
Authors: Radwan A. G. , Soliman A. M. , Elwakil A. S. 
Published: September 2007

AbstractFour practical sinusoidal oscillators are studied in the general form where fractional‐order energy storage elements are considered. A fractional‐order element is one whose complex impedance is given byZ = a(jω)±α, whereais a constant and α is not necessarily an integer. As a result, these oscillators are described by sets of fractional‐order differential equations. The integer‐order oscillation condition and oscillation frequency formulae are verified as special cases. Numerical and PSpice simulation results are given. Experimental results are also reported for a selected Wien‐bridge oscillator. Copyright © 2007 John Wiley & Sons, Ltd.
Universal resistorless current‐mode filters employing CCCIIs
Authors: Yuce Erkan , Kircay Ali , Tokat Sezai 
Published: September 2007

AbstractIn this paper, four different‐type second‐order current‐mode filters, employing second‐generation current‐controlled conveyors (CCCIIs) and two capacitors, are proposed. The first two of the presented filters can simultaneously realize high‐output impedance low‐pass, band‐pass and high‐pass responses. Also, the two filters can provide notch and all‐pass filter responses with interconnection of the relevant output currents. The first developed one needs no critical active and passive element matching conditions and/or cancellation constraints. The second and third introduced ones employ only grounded capacitors. The fourth proposed filter derived from the third one uses only plus‐type single output CCCIIs (CCCII+s). The fifth filter can be constructed using commercially available active devices such as AD844s along with additional resistors instead of CCCII+s of the fourth proposed filter to perform experimental test easily. All of the proposed filters have low active and passive element sensitivities. Time and frequency domain analyses are performed for the first, second and third realized filters using SPICE simulation program. Also, experimental test is achieved for the fifth filter. In this study, stability problems attributed to non‐ideal gains of the CCCIIs and signal limitations of the first, second and third introduced filters due to restricted power supply voltages are investigated.

CFA‐based grounded‐capacitor operational simulation of ladder filters
Authors: Rathore T. S. , Khot U. P. 
Published: September 2007

AbstractA systematic method for deriving CFA‐based all‐grounded‐capacitor filters from current modeRLCprototype ladder has been given. It is based on the operational simulation of node voltages and branch currents. It is extended to a voltage‐mode ladder. These filters employ a minimum number of capacitors and minimum total capacitance. In some cases, all the capacitors can be made of equal value. Such filters are suitable for fabrication in integrated circuit technology. Illustrative examples for realizing generic filters are included with their simulation results.

Performance comparison between fixed length switching and variable length switching
Authors: Hu Chengchen , Li Wenjie , Chen Xuefei , Liu Bin 
Published: September 2007

AbstractFixed length switching (FLS) and variable length switching (VLS) are two main types of switching architecture in high‐speed input‐queued switches. FLS is based on a cell‐by‐cell scheduling algorithm, while VLS operates on the variable packet granularity. This paper aims to make a comprehensive comparison between these two switching modes to guide the industrial design and academic research. We use stochastic models, Petri net models, analysis and simulations to investigate various performance measures of interest. Average packet latency, bandwidth utilization, segmentation and reassembly overhead, as well as packet loss are the identified key parameters that influence the outcome of the comparison. The results achieved in this paper are twofold. On one hand, it is shown that FLS enables smaller packet loss and lower packet delay in case of a short packet. On the other hand, VLS favors better bandwidth utilization, reduced implementation complexity and lower average packet delay. We recommend VLS in the conclusion since its disadvantages can be compensated by some methods, while the problems in FLS are difficult to be solved. Copyright © 2007 John Wiley & Sons, Ltd.
ß‐cell function and anti‐diabetic pharmacotherapy
Authors: Del Prato Stefano , Bianchi Cristina , Marchetti Piero 
Published: September 2007

AbstractType 2 diabetes is a chronic disease characterized by progressive worsening of glycaemic control as indicated by the United Kingdom Prospective Diabetes Study (UKPDS). The progressive nature of the disease is mainly due to continuous loss of β‐cell mass and function. Though much of this loss is due to intrinsic defects of the β‐cell several factors may accelerate such process. These include the metabolic environment where hyperglycaemia and increased circulating free‐fatty acid exert a toxic effect on the β‐cell. Therefore, tight metabolic control may prevent not only the risk of long‐term diabetic complication but also preserve β‐cell function. Several therapeutic agents are currently used for treatment of type 2 diabetic patients. However, their effect on maintenance of β‐cell function has not been yet systematically reviewed. By literature searching we have then analysed in detail the effect of sulfonylureas and non‐sulfonylureic secretagogues, incretin‐mimetics, insulin sensitizers, α‐glucosidase inhibitors, and insulin on β‐cell function. Moreover, promising future approaches aiming at preserving β‐cell function and mass are discussed. Copyright © 2007 John Wiley & Sons, Ltd.
