Experimental analysis of SIMD recursive digital filtering on the PASM system prototype (2003)

Experimental analyses of an implementation of an SIMD algorithm for recursive digital filtering using the partitionable SIMD/MIMD (PASM) parallel processing system prototype at Purdue University are presented. The algorithm used easily generalizes to use N processing elements (PEs). Timing-based analyses are made based on a four-PE version by examining the following constituent execution times: microcontroller execution time, PE execution time, broadcast communication time, and the execution time of five additional phases in the recursive digital filtering summation calculation. Broadcast execution time was found to account for roughly 44% of the total execution time, and the implication of this is discussed for larger problem sizes and machine sizes. The total measured execution time is verified through summation of execution times for the various components of the algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A 0.11mm⁁2 150mW 10GBase-T transmitter in 28nm CMOS process (2015)

The presented IEEE802.3an 10GBASE-T transmitter utilized a current-steering DAC and low voltage line driver to achieve the low power requirement. A self-regulated amplifier is used to enhance the operating bandwidth without common mode feedback stability limitation. By using a non-cascode current driver, the center-tap voltage can be lowered to 1. 6 V so that power consumption can be reduced dramatically. The design achieves TX SFDR > 60dB with 2Vppd swing across 400 MHz band and 150mW power consumption. The transmitter is implemented in a 28nm CMOS process with 1.8V/ 1V power domain and occupies an area of 0.11 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .
Determination of solid solubility limit of In and Sb in Si using bonded silicon-on-insulator (SOI) substrate (2002)

An SOI substrate enables us to obtain high, even distribution of impurity concentration in ion implantation with subsequent high-temperature annealing. We evaluated the solid solubility limit of In and Sb in Si by Hall measurement. We found that the solid solubility of In was constant at 1.5/spl times/10/sup 18/ cm/sup -3/ between 800/spl deg/C and 1100/spl deg/C, while that of Sb varied from 7/spl times/10/sup 19/ cm/sup -3/ at 800/spl deg/C to 1.2/spl times/10/sup 20/ cm/sup -3/ at 1100/spl deg/C, both of which were higher than previously reported values.
Fair Scheduling With QoS Support in Wireless Ad Hoc Networks (2004)

We study fair scheduling with quality of service (QoS) support for wireless ad hoc networks. Two types of flows are considered: best effort and guaranteed flows. The goal is to satisfy the minimum bandwidth requirements of guaranteed flows and to provide a fair share of residual bandwidth to all flows. We compare timestamp-based and credit-based mechanisms, and evaluate the feasibility of all existing fair scheduling schemes of these two types of mechanisms for multimedia wireless multihop networks. We suggest a flow weight calculation scheme for existing timestamp-based mechanisms to support both best effort and guaranteed flows, and propose a credit-based mechanism called credit-based slot allocation protocol (CSAP) for fair scheduling with QoS support. For comparison purposes, several metrics are defined to evaluate the performances of these two kinds of mechanisms. The simulation results show that CSAP outperforms the other approaches in terms of meeting the minimum requirements of guaranteed flows, fairly sharing the residual bandwidth among all flows, and improving overall system throughput.

Nonstationary spectral modeling of voiced speech (1983)

The main purpose of this paper is to present a novel model for voiced speech. The classical model, which is being used in many applications, assumes local stationarity, and consequently imposes a simple and well known line structure to the short-time spectrum of voiced speech. The model derived in this paper allows for local non-stationarities not only in terms of pitch perturbations, but in terms of vocal tract variations as well. The resulting structure of the short-time spectrum becomes more complex, but can still be interpreted in terms of generalized lines. The proposed model supports new forms of spectral prediction, which can be put to advantage in speech coding applications. Experimental results are presented supporting the validity of both the model itself and the prediction relationships. Finally, a new class of speech coders, denoted harmonic coders, based on the presented model, is proposed, and a specific implementation is presented.
Comparative performance of singly salient reluctance, switched reluctance, and induction motors (1997)

Reluctance motors, both singly and doubly salient, are receiving ever increasing interest because of their low cost, rugged construction, and high performance. This is particularly true when the reluctance motors are excited by currents which are synchronized with the rotor position, as is the case in this paper. The doubly salient reluctance motor, with position-synchronised excitation, is commonly referred to as a Switched Reluctance Motor (SRM). The paper compares a singly salient reluctance motor (SSRM), an SRM, and an 'off the shelf induction motor (IM). Every attempt has been made to make this comparison fair'. All three motors have the same cooling, use the same frame, have the same temperature rise, use the same air gap, and use the same steel. The paper concludes that both of the reluctance motors have superior performance to the IM and that the SRM has superior performance to the SSRM. The comparison is for D80 sized motors with a nominal top speed of 1500 rpm.

Shrink-film microfluidic education modules: Complete devices within minutes (2011)

As advances in microfluidics continue to make contributions to diagnostics and life sciences, broader awareness of this expanding field becomes necessary. By leveraging low-cost microfabrication techniques that require no capital equipment or infrastructure, simple, accessible, and effective educational modules can be made available for a broad range of educational needs from middle school demonstrations to college laboratory classes. These modules demonstrate key microfluidic concepts such as diffusion and separation as well as "laboratory on-chip" applications including chemical reactions and biological assays. These modules are intended to provide an interdisciplinary hands-on experience, including chip design, fabrication of functional devices, and experiments at the microscale. Consequently, students will be able to conceptualize physics at small scales, gain experience in computer-aided design and microfabrication, and perform experiments-all in the context of addressing real-world challenges by making their own lab-on-chip devices.
Modeling Traffic Prediction Uncertainty for Traffic Management Decision Support (2004)

TFM personnel are known as Traffic Management Coordinators (TMCs) or Traffic Management Specialists (TMSs), depending on the facility in which they work. The general term for these personnel is traffic managers. One of their primary responsibilities is to ensure that traffic at national airspace system (NAS) resources (e.g., airspace sectors, airports) does not exceed levels that can be safely managed by controllers. Traffic managers also endeavor to ensure fair and equitable treatment for all NAS users, i.e., operators of commercial, general aviation, military, and other aircraft. Air Traffic Flow Management (TFM) is the process of balancing demand for airspace and airport resources with the capacity of those resources, in order to achieve both safe and efficient traffic throughput. Demand is typically estimated by predicting flight trajectories, and comparing the predictions to capacity metrics for airports and airspace. The effectiveness of TFM decision-making depends on the accuracy of these predictions. This effectiveness can be improved not only by improving prediction accuracy, but by quantifying the uncertainty in those predictions. When the uncertainty is known, decision analysis and risk management techniques can be applied to improve decision-making performance. To support this goal, a novel method has been developed for measuring and simulating uncertainty in traffic demand predictions. This method employs empirical observations of traffic characteristics to develop statistical models of the error distributions in demand predictions, which in turn can be used for Monte-Carlo simulation of specific traffic scenarios. Preliminary statistical results are presented here, as well as a discussion of simulation applications for both analysis and real-time decision-support tasks.
Routing and Wavelength Assignment of Static Manycast Demands Over All-Optical Wavelength-Routed WDM Networks (2010)

In this paper we present the static manycast routing and wavelength assignment (MA-RWA) problem along with heuristics and an integer linear program (ILP) to solve it. Manycast is a point-to-multipoint communication paradigm with applications in e-Science, Grid, and cloud computing. A manycast request specifies a candidate set of destinations, of which a subset must be reached. To solve MA-RWA, a light-tree must be assigned to each manycast request in a static set such that the number of wavelengths required is minimized. We present two heuristics, the shortest path heuristic (SPT) and the lambda path heuristic (LPH), a tabu search meta-heuristic (TS), and an ILP formulation. We show that TS provides results close to the optimal solution (from the ILP) for small networks. We then show that TS provides a 10% improvement over LPH and a 30%–40% improvement over SPT for various realistic networks.
Exploiting Workload Characteristics and Service Diversity to Improve the Availability of Cloud Storage Systems (2015)

With the increasing utilization and popularity of the cloud infrastructure, more and more data are moved to the cloud storage systems. This makes the availability of cloud storage services critically important, particularly given the fact that outages of cloud storage services have indeed happened from time to time. Thus, solely depending on a single cloud storage provider for storage services can risk violating the service-level agreement (SLA) due to the weakening of service availability. This has led to the notion of Cloud-of-Clouds, where data redundancy is introduced to distribute data among multiple independent cloud storage providers, to address the problem. The key in the effectiveness of the Cloud-of-Clouds approaches lies in how the data redundancy is incorporated and distributed among the clouds. However, the existing Cloud-of-Clouds approaches utilize either replication or erasure codes to redundantly distribute data across multiple clouds, thus incurring either high space or high performance overheads. In this paper, we propose a hybrid redundant data distribution approach, called HyRD, to improve the cloud storage availability in Cloud-of-Clouds by exploiting the workload characteristics and the diversity of cloud providers. In HyRD, large files are distributed in multiple cost-efficient cloud storage providers with erasure-coded data redundancy while small files and file system metadata are replicated on multiple high-performance cloud storage providers. The experiments conducted on our lightweight prototype implementation of HyRD show that HyRD improves the cost efficiency by 33.4 and 20.4 percent, and reduces the access latency by 58.7 and 34.8 percent than the DuraCloud and RACS schemes, respectively.
The human heat shock protein hsp70 interacts with HSF, the transcription factor that regulates heat shock gene expression. (1992)

Transcriptional regulation of the human hsp70 gene in response to heat shock and other forms of physiological stress occurs through the activation of heat shock transcription factor (HSF). Exposure of cells to a heat shock temperature of 42 degrees C results in transient activation of HSF; its DNA-binding activity increases rapidly, plateaus, and attenuates, during which the intracellular levels of hsp70 increase. In an effort to understand whether HSF is regulated negatively by hsp70, we have examined whether HSF associates with hsp70. We show that activated HSF associates with hsp70 and that the interaction is detected as the levels of hsp70 increase in the cell. Addition of ATP and other hydrolyzable nucleotides results in the dissociation of hsp70 from HSF while nonhydrolyzable nucleotide analogs do not disrupt the complex. We demonstrate that exogenous recombinant wild-type hsp70 can associate with activated HSF, whereas no association is observed with an amino-terminal or a carboxy-terminal deletion mutant of hsp70. We also show that hsp70 blocks the in vitro activation of HSF from its cryptic non-DNA-binding state to a DNA-binding form; this inhibitory effect of hsp70 is abolished by ATP. We suggest that hsp70 may negatively regulate the activation of HSF.
The EMI improvement on active filter using common-mode noise circuits balanced method (2015)

This paper presents the electromagnetic interference (EMI) improvement on active filter using common-mode noise circuits balanced method. The main objective is to reduce the electromagnetic interference (EMI) by reducing the common-mode noise current being generated from the effect of PWM signal of active filter. For this reason, this common-mode noise current flows through the reference ground and generates the conducted noise emission flowing around the circuit. Thus, this paper suggests the common-mode circuit balanced method by modifying the impedance of common-mode circuit impedance. The result shows that the common-mode currents is cancelled themselves. From the experimental results, both the spectrum of conductive noise before and after improving is compared.
System and performance design of the ATM node UT-XC (2002)

A large debate is going on around the possible use of the ATM network. The public TLC want a QoS guaranteed ATM network that can be used for the implementation of B-ISDN. The data communication operators ask for an ATM based backbone network, starting from interconnecting LANs. This forces the design of the ATM network nodes to be flexible and robust to face alternatives application scenarios. Taking care of this requirement, the system and performance design of the Italtel ATM node UT-XC are presented. The design of the node is based on a set of elementary building blocks, each realizing in hardware specific functionalities required for ATM switching. A high level of traffic performance is obtained using the internal speed advantage and cell distribution routing in the switching network. To rebuild the cell sequence integrity, a maximum delay equalization principle is used at node egress, which minimizes cell delay variation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Intestinal lengthening: an experimental and clinical review. (1984)

Small intestinal lengthening by the Bianchi procedure has now had successful clinical application in children and neonates with the short-bowel syndrome. This paper reviews the background experimental work and clinical cases so far treated. A personal case of intestinal lengthening in a 7-week-old baby with 35 cm jejunum is described in detail. Intestinal lengthening appears to reduce dependence on parenteral nutrition, thus allowing earlier establishment of total enteral alimentation. The procedure may therefore have a useful place in the overall management of the short-bowel syndrome.

An Efficient Flexible Common Operator for FFT and Viterbi Algorithms (2011)

Today's telecommunication systems require more and more flexibility, and reconfiguration mechanisms are becoming major topics especially when it comes to multi-standard designs. This paper capitalizes on the Common Operator technique to present a new common operator for the FFT and Viterbi algorithms. In the present work, the FFT/Viterbi common butterfly is investigated where reuse and power consumption is traded against throughput. Performance comparisons with similar works are discussed in this paper.
THE IMMUNOSUPPRESSIVE ACTION OF FK 506 (1990)

FK506 is an unusually potent new immunosuppressive agent that inhibits T cell-mediated immunity in vivo and in vitro. In these studies we sought to further elucidate the immunosuppressive mechanism of action of FK506 on human allogeneic MLR-induced CTL activation. FK506 induced suppression of cell-mediated lympholysis by PBMC was optimal at 1-2-nM concentrations, if added at the initiation of 6 day CML cultures. The sensitivity to suppression decreased with time, and fully differentiated effectors were resistant to inhibition by FK506. Suppression of CML was not reversed by washing the cultures, adding exogenous IL-2, or restimulating with fresh cells. Pretreatment of unfractionated or adherent allogeneic PBMC with FK506 blocked the stimulating activity of these cells. Furthermore, addition of FK506-treated stimulator cells to cocultures containing untreated responder and stimulator cells resulted in suppression of CML. The inhibition in the cocultures was greatest if the FK506-pretreated cells were autologous to the original stimulator, suggesting a relative specificity in the suppression obtained under these conditions. These studies suggest that, in addition to suppressing the response of alloreactive CTL precursors, FK506 reduces the ability of irradiated allogeneic PBMC to induce CTL generation.

Influence of Silica Fume on the Workability and the Compressive Strength of High-Performance Concretes (1998)

The workability and the compressive strength of silica fume concretes were investigated at low water-cementitious materials ratios with a naphthalene sulphonate superplasticizer. The results show that partial cement replacement up to 10% silica fume does not reduce the concrete workability. Moreover, the superplasticizer dosage depends on the cement characteristics (C3A and alkali sulfates content). At low water-cementitious materials ratios, slump loss with time is observed and increases with high replacement levels. Silica fume at replacement contents up to 20% produce higher compressive strengths than control concretes; nevertheless, the strength gain is less than 15%. In this paper, we propose a model to evaluate the compressive strength of silica fume concrete at any time. The model is related to the water-cementitious materials and silica-cement ratios. Taking into account the author’s and other researchers’ experimental data, the accuracy of the proposed model is better than 5%.
Atomic Layer Deposition of Iron Oxide Thin Films and Nanotubes using Ferrocene and Oxygen as Precursors (2008)

Abstract Thin films and nanotubes of iron oxide are deposited using atomic layer deposition (ALD) on Si(100) and anodic aluminum oxide (AAO), respectively. Ferrocene, Fe(Cp) 2 , and oxygen are used as precursors. Successful depositions are carried out in the temperature range 350–500 °C on Si(100), while all depositions on AAO are made at 400 °C. The growth per cycle values are around 0.14 nm on Si(100) in the temperature range 350–500 °C and 0.06 nm on AAO. Below 500 °C, the iron oxide crystallizes as a phase mixture on both types of substrates. One of the phases is identified as the rhombohedral Fe 2 O 3 phase (hematite), but the second phase cannot be unambiguously identified. Above 500 °C, only phase pure hematite is detected. For deposition of nanotubes, in‐house made AAO membranes are used, having an aspect ratio of 30. By etching of the AAO membranes after deposition, free‐standing nanotubes retaining the order of the AAO template can be fabricated.
Gelatin and Hydroxyethyl Starch, but Not Albumin, Impair Hemostasis After Cardiac Surgery (2006)

We investigated the effect of postoperative administration of colloids on hemostasis in 45 patients after cardiac surgery. Patients were randomized to receive 15 mL kg(-1) of either 4% albumin, 4% succinylated gelatin, or 6% hydroxyethyl starch (molecular weight of 200 kDa/degree of substitution 0.5) as a short-term infusion. There was a comparable decrease in maximum clot firmness of thromboelastometry tracings in gelatin and hydroxyethyl starch groups immediately after completion of the infusion, whereas these values remained unchanged in the albumin group. The impairment in clot strength persisted up to 2 h, although the values partly recovered. Postoperative bleeding correlated inversely with the clot strength in pooled data of the artificial colloids. Fibrin formation (clot formation time, alpha-angle) and fibrinogen-dependent clot strength (maximum clot firmness and shear elastic modulus) were more disturbed in the hydroxyethyl starch group than in the gelatin group. We conclude that after cardiopulmonary bypass surgery, both gelatin and hydroxyethyl starch impair clot strength and fibrin buildup, which may predispose patients to increased blood loss. The greatest impairment in hemostasis was seen after hydroxyethyl starch administration, whereas albumin appeared to have the least effect on hemostatic variables.
