Gait control of biped robot based on kinematics and motion description in Cartesian space (2002)

This paper proposes a new simple 3-D (three dimension) dynamic gait control scheme for a walking biped robot based on kinematics calculation and robust joint solution control. The 3-D dynamic gait motion of the biped robot is approximated to the inverted pendulums for the sagittal plane and lateral plane in Cartesian space. Using the kinematics calculation of biped robots and the robust joint position controller of each joint, both the top positions of the supporting leg and floating leg track each position reference robustly. Experimental results of the tested ten-joints biped robot confirm that the proposed method realizes 3-D dynamic gait control stably.
Spark‐Plasma Sintering of Silicon Carbide Whiskers (SiC w ) Reinforced Nanocrystalline Alumina (2004)

The combined effect of rapid sintering by spark‐plasma‐sintering (SPS) technique and mechanical milling of γ‐Al 2 O 3 nanopowder via high‐energy ball milling (HEBM) on the microstructural development and mechanical properties of nanocrystalline alumina matrix composites toughened by 20 vol% silicon carbide whiskers was investigated. SiC w /γ‐Al 2 O 3 nanopowders processed by HEBM can be successfully consolidated to full density by SPS at a temperature as low as 1125°C and still retain a near‐nanocrystalline matrix grain size (∼118 nm). However, to densify the same nanopowder mixture to full density without the benefit of HEBM procedure, the required temperature for sintering was higher than 1200°C, where one encountered excessive grain growth. X‐ray diffraction (XRD) and scanning electron microscopy (SEM) results indicated that HEBM did not lead to the transformation of γ‐Al 2 O 3 to α‐Al 2 O 3 of the starting powder but rather induced possible residual stress that enhances the densification at lower temperatures. The SiC w /HEBMγ‐Al 2 O 3 nanocomposite with grain size of 118 nm has attractive mechanical properties, i.e., Vickers hardness of 26.1 GPa and fracture toughness of 6.2 MPa·m 1/2 .
Search for New and Novel Chemotherapeutics for the Treatment of Human Malignancies (2010)

One of the hallmarks of cancer is the uncontrolled cell proliferation which causes more deaths among the human diseases throughout the globe. One in eight deaths worldwide are due to cancer, it is the second and third leading cause of death in economically developed and developing countries, respectively. As it is caused by both external and internal factors, a balanced approach to cancer control includes prevention, early detection, and effective treatment. In the treatment of cancer, chemotherapy is one of the practical methods and is widely used employing drugs that can destroy cancer cells by impeding their growth and reproduction. Despite the great strides made in the treatment of cancer over the past 50 years, it continues to be a major health concern and therefore, extensive efforts have been devoted to search for new scaffolds to develop chemotherapeutics. In this perspective, over the past two decades from this laboratory extensive efforts have been made in the development of new chemotherapeutic agents for the treatment of cancer. In this review, glimpses on types of current chemotherapeutic agents based on their action of inhibition and the new molecules that are being developed based on the scaffolds such as pyrrolo[2,1-c][1,4]benzodiazepines, podophyllotoxins, benzothiadiazine 1,1-dioxides, naphthalimides and monastrol across the world as well as in this laboratory have been articulated.
Controlled trial of an anticoagulant (warfarin sodium) in the prevention of venous thrombosis following hip surgery (1970)

Abstract A prospective study was undertaken to assess the value of warfarin sodium, given prophylactically, in the prevention of postoperative deep-vein thrombosis. The radio-isotope method was used for the detection of venous thrombosis and the results obtained were compared with physical signs of the disease process and phlebography. Fifty consecutive patients over the age of 50 years, undergoing hip operations, were studied. Twenty-five patients were treated with warfarin sodium and 25 acted as controls. Nine in the treated group and 8 in the control group developed postoperative deep-vein thrombosis.

After the DNA-based diagnosis of BKPyV infection in KTRs, bkv-miR-B1-3p and bkv-miR-B1-5p levels in the urine might be valuable markers for viral replication monitoring and thus might help physicians to avoid an excessive reduction in the immunosuppressive regimen.
Guiding the Way (2014)

This article introduces the reader to literature, ideas, and processes the authors have used in mentoring graduate students and junior faculty of color, including women. The writing is based on an integrative review of literature engaging mentoring processes and the authors’ collective experiences as they have worked to guide members of a mentoring collective as well as domestic graduate students and junior faculty from the above populations. Goals of our mentoring efforts are to provide graduate students and junior faculty who are from U.S. cultural communities historically excluded from higher education with experiences that help them complete the PhD and develop professional academic careers that are successful and have impact in their chosen disciplinary arena. The article presents a mentoring process model that prepares individuals for professional careers that integrate the work of knowledge production in research, teaching, and service that embraces the cultural heritages of the mentees’ background.
Unstable behavior of plasma in inductive discharges (2003)

Summary form only given. Instabilities in a transformer coupled plasma (TCP) source have been studied. An inductive discharge has been created by a 13.56 MHz RF-driven planar inductive coil mounted on the top of an aluminum cylindrical vacuum chamber. Electronegative gases such as O/sub 2/ and SF/sub 6/ and their mixtures with Ar have been used as operating gases. To detect plasma instabilities, time-resolved diagnostics have been used including optical emission spectroscopy and Langmuir probe measurements of the ion current. Instabilities have been observed in a transition region where the discharge changes its mode from capacitive (E-mode) to inductive (H-mode). Frequencies of plasma fluctuations (fluctuations of the ion current or intensity of the light emitted from the plasma) were in the range of 1 Hz-0.9 MHz for operating gas pressures of 2.5-20 mTorr and an absorbed power of 150-600 W. These plasma instabilities may be related to a hysteresis-like behavior of the inductive discharge in the E-H transition region and associated with the balance of power absorbed and lost by electrons.
A Secure Access Control System (2012)

We, three students from the TU Delft, have created a new Secure Access Control System, named Glados. The goal of this system is to limit the access to a building, and separate 'zones' in that building, to authorized persons only. In 10 weeks, we created a prototype that can read an authentication token, and react with the permission from a central server. Each door in a building can be equipped with a small computing device and token readers (one for each side of the door). The device (called a 'Portal') communicates with the central server, where the information about people and their access rights are stored. Our primary concerns were security and maintainability. Special care has been taken in identifying possible attack vectors and defending against those. This includes using high-end authentication chips, encryption of communication and centralizing sensitive data.
A Spatial-Cue-Based Probabilistic Model for Bird Song Scene Analysis (2017)

This paper addresses bird song scene analysis focusing on location of birds and acoustic features of bird songs. Such a research area usually requires manual annotation related to positions and/or vocalization types of the target animals for a large amount of observed data. However, this manual annotation has two problems. One is that it is tough to annotate data observed in real environments because environmental noise exist and sound is reflected by trees and the ground, and also several birds at different locations may sing at the same time. The other is that it is inevitable that manual annotation produces inaccurate and inconsistent labels due to human errors and annotators' individual differences. For the first problem, we propose a Spatial-Cue-Based Probabilistic Model (SCBPM), which is a probabilistic model to estimate the maximum likelihood result for a bird song scene analysis by integrating sound source detection, localization, separation and identification based on spatial information of sound sources. For the second problem, we employ a semiautomatic annotation approach, in which a semi-supervised training method is deduced for SCBPM. This method decreases the amount of manual annotation. Preliminary experiments using recorded bird song data from the wild revealed that our system outperformed a conventional bird song scene analysis system by simply connecting sound source detection, localization, separation and identification in a cascade way in terms of identification accuracy.

A Comparison of High Temperature Performance of SiC DMOSFETs and JFETs (2007)

High temperature characteristics of 4H-SiC power JFETs and DMOSFETs are presented in this paper. Both devices are based on pn junctions in 4H-SiC, and are capable of 300oC operation. The 4H-SiC JFET showed very predictable, well understood temperature dependent characteristics, because the current conduction depends on the drift of electrons in the bulk region, which is not restricted by traps in the MOS interface or at the pn junctions. On the other hand, in a 4H-SiC DMOSFET, electrons must flow through the MOS inversion layer with a very high interface state density. At high temperatures, the transconductance of the device improves and threshold voltage shifts negative because less electrons are trapped in the interface states, resulting in a much lower MOS channel resistance. This cancels out the increase in drift layer resistance, and as a result, a temperature insensitive on-resistance can be demonstrated. The performance of the two devices are compared, and a discussion of issues for their high temperature application is presented.
High-Field Transport and Thermal Reliability of Sorted Carbon Nanotube Network Devices (2012)

We examine the high-field operation, power dissipation, and thermal reliability of sorted carbon nanotube network (CNN) devices, with <1% to >99% semiconducting nanotubes. We combine systematic electrical measurements with infrared (IR) thermal imaging and detailed Monte Carlo simulations to study high-field transport up to CNN failure by unzipping-like breakdown. We find that metallic CNNs carry peak current densities up to an order of magnitude greater than semiconducting CNNs at comparable nanotube densities. Metallic CNNs also appear to have a factor of 2 lower intrinsic thermal resistance, suggesting a lower thermal resistance at metallic nanotube junctions. The performance limits and reliability of CNNs depend on their makeup, and could be improved by carefully engineered heat dissipation through the substrate, contacts, and nanotube junctions. These results are essential for optimization of CNN devices on transparent or flexible substrates which typically have very low thermal conductivity.
LP-TRAP: linear predictive temporal patterns (2004)

Autoregressive modeling is applied for approximating the temporal evolution of spectral density in critical-band-sized subbands of a segment of speech signal. The generalized autocorrelation linear predictive technique allows for a compromise between fitting the peaks and the troughs of the Hilbert envelope of the signal in the sub-band. The cosine transform coefficients of the approximated sub-band envelopes, computed recursively from the all-pole polynomials, are used as inputs to a TRAP-based speech recognition system and are shown to improve recognition accuracy.
Parametric model extraction for mems based on variational finite element techniques (2005)

This article is focused on new finite element technologies which account for parameter variations in a single finite element run. The key idea of the new approach is to compute not only the governing system matrices of the FE problem but also n high order partial derivatives with regard to design parameters by means of automatic differentiation (AD). As result, Taylor vectors of the system's response can be expanded in the vicinity of the initial position capturing dimensions and physical parameter. Essential speed-up can be achieved for shape optimization, sensitivity analyses and data sampling needed for reduced order modeling of MEMS.

An Untethered Brittle Star-Inspired Soft Robot for Closed-Loop Underwater Locomotion (2020)

Soft robots are capable of inherently safer interactions with their environment than rigid robots since they can mechanically deform in response to unanticipated stimuli. However, their complex mechanics can make planning and control difficult, particularly with tasks such as locomotion. In this work, we present a mobile and untethered underwater crawling soft robot, PATRICK, paired with a testbed that demonstrates closed-loop locomotion planning. PATRICK is inspired by the brittle star, with five flexible legs actuated by a total of 20 shape-memory alloy (SMA) wires, providing a rich variety of possible motions via its large input space. We propose a motion planning infrastructure based on a simple set of PATRICK's motion primitives, and provide experiments showing that the planner can command the robot to locomote to a goal state. These experiments contribute the first examples of closed-loop, state-space goal seeking of an underwater, untethered, soft crawling robot, and make progress towards full autonomy of soft mobile robotic systems.
A new modulation method for the modular multilevel converter allowing fundamental switching frequency (2011)

This paper presents a new modulation method for the modular multilevel converter. The proposed method is based on a fixed pulse pattern where harmonic elimination methods can be applied. Modulation methods with harmonic elimination based on calculated pulse patterns have been presented for other multilevel topologies. However, similar modulation schemes have not yet been presented for the modular multilevel topology. In the proposed modulation method, the pulse pattern is chosen in such a way that the stored energy in each submodule remains stable. It is shown that this can be done at the fundamental switching frequency without measuring the capacitor voltages or using any other form of feedback control. Such a modulation scheme has not been presented before. The theoretical results are verified by both simulations and experimental results. The simulation results show successful operation at the fundamental switching frequency with a larger number of submodules. When a smaller number of submodules are used, harmonic elimination methods may be applied. This is verified experimentally on a converter with eight submodules per phase leg. The experimental results verify that stable operation can be maintained at the fundamental switching frequency while successfully eliminating the fifth harmonic in the ac-side voltage.
SAT-178 Parasitoid Wasp Venom Elevates Sorbitol and Alters Expression of Metabolic Genes in Human Kidney Cells (2019)

Venom from the parasitoid wasp Nasonia vitripennis dramatically elevates sorbitol levels in its natural fly hosts. In humans, sorbitol elevation is associated with complications of diabetes. Here we demonstrate that venom also induces this disease-relevant phenotype in human cells, and investigate possible pathways involved. Key findings are that (a) low doses of Nasonia venom elevate sorbitol levels in human renal mesangial cells (HRMCs) without changing glucose or fructose levels; (b) venom is a much more potent inducer of sorbitol elevation than glucose; (c) low venom doses significantly alter expression of genes involved in sterol and alcohol metabolism, transcriptional regulation, and chemical/stimulus response; (d) although venom treatment does not alter expression of the key sorbitol pathway gene aldose reductase (AR); (e) venom elevates expression of a related gene implicated in diabetes complications (AKR1C3) as well as the fructose metabolic gene (GFPT2). Although elevated sorbitol is accepted as a major contributor to secondary complications of diabetes, the molecular mechanism of sorbitol regulation and its contribution to diabetes complications are not fully understood. Our findings suggest that genes other than AR could contribute to sorbitol regulation, and more broadly illustrate the potential of parasitoid venoms for medical application.

Doppler Shift Estimation in 5G New Radio Non-Terrestrial Networks (2021)

Evolving 5G New Radio (NR) to support non-terrestrial networks (NTNs), particularly satellite communication networks, is under exploration in 3GPP. The movement of the spaceborne platforms in NTNs may result in large timing varying Doppler shift that differs for devices in different locations. Using orthogonal frequency-division multiple access (OFDMA) in the uplink, each device will need to apply a different frequency adjustment value to compensate for the Doppler shift. To this end, the 3GPP Release-17 work on NTNs assumes that an NTN device is equipped with a global navigation satellite system (GNSS) chipset and thereby can determine its position and calculate the needed frequency adjustment value using its position information and satellite ephemeris data. This makes GNSS support essential for the NTN operation. However, GNSS signals are weak, not ubiquitous, and susceptible to interference and spoofing. We show that devices without access to GNSS signals can utilize reference signals in more than one frequency position in an OFDM carrier to estimate the Doppler shift and thereby determine the needed frequency adjustment value for pre-compensating the Doppler shift in the uplink. We analyze the performance, elaborate on how to utilize the NR reference signals, and present simulation results. The solution can reduce the dependency of NTN operation on GNSS with reasonable complexity and performance trade-off.
Conceptual design and evaluation of an ultrasonic system for bottled beverages’ quality measurement and control (2004)

A conceptual design of an online ultrasonic system for bottled beverages’ quality control and monitoring is presented. The design consists of being able to measure ultrasound propagation velocities of beverages in each glass bottle without needing to know its diameter and wall thickness. This was achieved using simultaneously both ultrasound pulse/echo and thru-transmission signals. The ultrasound velocity is then correlated with the beverage’s, viscosity, which is an index of quality. The design also includes: (1) an online transducer alignment technique using a mechanism of frequency shift in spectrum of an ultrasonic pulse signal according to incident angle, and (2) a signal processing method using a slide window technique suitable for automatic separation and recognition of narrowly spaced pulse signals. Experiments were conducted to evaluate the design. Results of beverage viscosity/velocity correlation, frequency shift due to transducer alignment, and ultrasound velocity measurement in real bottles are reported.
