Model-based Design and Simulation of a Soft Robotic Gripper for Fabric Material Handling (2021)

<title>Abstract</title> <italic>Fabric and textile materials are widely used in many industrial applications, especially in automotive, aviation, and consumer goods. Currently, there is a lack of automatic solutions for rapid and effective fabric handling operations that can be expanded to various applications, causing economic loss, workplace safety issues, and process bottlenecks. As a bio-inspired novel technology, soft robotic grippers provide new opportunities for the automation of fabric handling tasks. In this research, an elastomer-based tendon-actuated soft gripper for fabric pick and place tasks is developed through a model-based design approach. Based on finite element analysis, the gripper design is simulated, modified, and validated. Multiple design variables and their impacts are studied. Detailed motion patterns of the underactuated structure are obtained. After the design is established, a prototype is fabricated trough additive manufacturing and overmolding processes to physically test the functionality of the gripper and further validate the simulation results.</italic>

Changes in airborne pollen concentrations in Delhi, India (2003)

In order to find the qualitative and quantitative changes in airborne pollen concentrations in Delhi metropolis area an aerobiological survey was undertaken from September 1990 to August 1997. Air samples were collected daily using a Rotorod Aeroallergen Sampler at 10 m above the ground level. Ninety-four pollen types were recorded and the major contributors include Morus, Cannabis, Chenopod/Amaranth, Prosopis, Artemisia, and Eucalyptus. Ten pollen types contributed 90% of the total pollen load. Two major pollen seasons were recorded each year (February–April and September–November), although pollen grains in low frequency were recorded throughout the whole year. A significant reduction in pollen concentration was observed in subsequent years. The number of Morus, Cannabis, Prosopis, and Artemisia pollen decreased considerably while the number of Ricinus communis pollen did not show any considerable change during the study period. It is suggested that the reduction in pollen numbers from 1990 to 1997 in Delhi is due to massive clearing of vegetation for developmental activities of the city.
Specificity of Hybridization between DNA Sequences Based on Free Energy (2006)

Abstract. We investigated the specificity of hybridization based on a minimum free energy (∆Gmin) through gel electrophoresis analysis. The analysis, using 94 pairs of sequences with length 20, showed that sequences that hybridize each other can be separated using the constraint ∆Gmin ≤ −14.0, but cannot be separated using the number of base pairs (BP) in the range from 9 to 18. This demonstrates that the ∆Gmin is superior to the BP in terms of the capability to separate specific from non-specific sequences. Furthermore, the comparison between sequence design based on ∆Gmin and that based on the BP, done through a computer simulation, showed that the former outperformed the latter in terms of the number of sequences designed successfully as well as the ratio of successfully designed sequences to the total number of sequences checked. 1
Ceramic / inorganic-organic nano-hybrid composites for thermally stable insulation of electrical wires. Part II: Properties of the composite insulated wires (2020)

The paper Part I reported on the fabrication of high temperature capable electrical wires insulated with a new type of composite coatings comprising particulate ceramics and silicon-containing inorganic-organic nano-hybrids. This second paper studies the thermal, mechanical and dielectric properties of these composite insulated wires in accordance with relevant national standards. Techniques for materials characterization were also applied to provide information for better understanding the coatings' performance as wire insulation. Results showed that insulated wires have moderate dielectric strength comparable to ceramic insulation and excellent thermal stability, with insulation sustained for over 100 days at 500°C and prolonged period at 450°C under constant high temperature ageing and there is no obvious insulation degradation after thermal cycling for 20 times. The insulated wires demonstrated good mechanical properties, with interim flexibility allowing a minimal bending radius of 3 mm for 1.2 mm insulated wires. The resistance to abrasion and cutting through are also good enough to satisfy most practical applications.
Surpassing Tradeoffs by Separation: Examples in Transmission Line Resonators, Phase-Locked Loops, and Analog-to-Digital Converters (2008)

We review three examples (an on-chip transmission line resonator [1], a phase-locked loop [2], and an analog-to-digital converter [3]) of design tradeoffs which can in fact be circumvented; the key in each case is that the parameters that seem to trade off with each other are actually separated in time or space. This paper is an attempt to present these designs in such a way that this common approach can hopefully be applied to other circuits. We note reader that this paper is not a new contribution, but a review in which we highlight the common theme from our published works [1-3]. We published a similar paper [4], which, however, used only two examples from [1] and [2]. With the newly added content from [3] in the list of our examples, the present paper offers an expanded scope.
Multi-wavelength investigation of laser-damage performance in KDP and DKDP following laser annealing (2004)

Rotation of the radius about the fixed ulna is analysed radiographically in an anatomic specimen. While rotating the styloid process of the radius migrates in relation to the ulna. Compared to the prone position supination leads to a more distal position of the styloid process.
Non‐water‐excitation MR spectroscopy techniques to explore exchanging protons in human brain at 3 T (2020)

Novel non-water-excitation MRS sequences offer substantial benefits for the detection of metabolite signals that are otherwise suppressed by saturation transfer from water. Avoiding water saturation and using very short echo times allows direct observation of faster exchanging moieties than was previously possible at 3 T and additionally makes the methods less susceptible to fast T<sub>2</sub> relaxation.
Two modes of DNA double-strand break repair are reciprocally regulated through the fission yeast cell cycle (2004)

Several considerations suggest that levels of the two major modes of double-strand break (DSB) repair, homologous recombination (HR), and nonhomologous end joining (NHEJ), are regulated through the cell cycle. However, this idea has not been explicitly tested. In the absence of the telomere-binding protein Taz1, fission yeast undergo lethal telomere fusions via NHEJ. These fusions occur only during periods of nitrogen starvation and fail to accumulate during logarithmic growth, when the majority of cells are in G2. We show that G1 arrest is the specific nitrogen starvation-induced event that promotes NHEJ between taz1(-) telomeres. Furthermore, the general levels of NHEJ and HR are reciprocally regulated through the cell cycle, so that NHEJ is 10-fold higher in early G1 than in other cell cycle stages; the reverse is true for HR. Whereas NHEJ is known to be dispensable for survival of DSBs in cycling cells, we find that it is critical for repair and survival of DSBs arising during G1.
165-OR: Antioxidant-Based Encapsulation Strategies to Enhance Islet Allotransplantation (2021)

The destruction of insulin-producing cells is a hallmark of type 1 diabetes (T1D) and results in a loss of glycemic control. Islet transplantation can restore glucose homeostasis and prevent hypoglycemic events; however, long-term graft survival is low. Oxidative stress mediates islet transplant rejection. Therefore, suppressing oxidative stress with nanothin encapsulation materials comprised of alternating layers of tannic acid (TA), an immunomodulatory antioxidant, and poly(N-vinylpyrrolidone) (PVPON), a scaffold polymer, may allow for improved graft survival. We hypothesize that (PVPON/TA)-encapsulation of islets will prolong graft function and delay allotransplantation rejection in the absence of systemic immunosuppression. We recently published that allogeneic transplantation of encapsulated C57BL/6 islets into NOD mice significantly delayed graft failure, decreased free radical-adduct formation, and reduced infiltrating immune cell effector responses. These data suggest local immunosuppression with (PVPON/TA)-encapsulation may be a promising technique to prolong islet graft function in islet allotransplants. To enhance immunosuppression, we conjugated CTLA-4-Ig to the outer surface of (PVPON/TA) layers. (PVPON/TA/CTLA-4)-encapsulated islets display significantly delayed allograft rejection compared to (PVPON/TA) controls. Flow cytometry analysis demonstrated reduced CD80/CD86 costimulatory receptor and MHC-II expression on innate immune populations, enhanced FOXP3+ regulatory T cells, and enhanced PD1+ CD8 T cells within (PVPON/TA/CTLA-4)-encapsulated grafts. To monitor graft integrity in vivo, we conjugated (PVPON/TA) layers with the fluorophore Cy5.5. Transplantation of (PVPON/TA/Cy5.5)-encapsulated islets restored glucose tolerance and was detected in vivo for up to eight weeks post-transplant. The ability to modify our (PVPON/TA) coatings opens the door for endless possibilities to improve clinical islet transplantation. Disclosure J. Barra: None. V. Kozlovskaya: None. E.

Compensation of magnetic disturbances improves inertial and magnetic sensing of human body segment orientation (2005)

This paper describes a complementary Kalman filter design to estimate orientation of human body segments by fusing gyroscope, accelerometer, and magnetometer signals from miniature sensors. Ferromagnetic materials or other magnetic fields near the sensor module disturb the local earth magnetic field and, therefore, the orientation estimation, which impedes many (ambulatory) applications. In the filter, the gyroscope bias error, orientation error, and magnetic disturbance error are estimated. The filter was tested under quasi-static and dynamic conditions with ferromagnetic materials close to the sensor module. The quasi-static experiments implied static positions and rotations around the three axes. In the dynamic experiments, three-dimensional rotations were performed near a metal tool case. The orientation estimated by the filter was compared with the orientation obtained with an optical reference system Vicon. Results show accurate and drift-free orientation estimates. The compensation results in a significant difference (p < 0.01) between the orientation estimates with compensation of magnetic disturbances in comparison to no compensation or only gyroscopes. The average static error was 1.4 degrees (standard deviation 0.4) in the magnetically disturbed experiments. The dynamic error was 2.6 degrees root means square.

Cost-Aware Streaming Data Analysis (2018)

Distributed systems have become the preferred solution for dealing with Big Data analysis tasks. These systems are able to achieve superior performance by managing a large pool of resources as a single entity. However, in many contexts, performance is not the only metric to consider. When comparing two performance equivalent solutions, their cost becomes an important factor. Distributed systems are usually more expensive to deploy than traditional single-threaded applications.
Segment Ghosting und Targeting in der Anflugplanung (2009)

Beim „Ghosting“ wird auf einem Radardisplay das Label eines Luftfahrzeugs zusätzlich auf eine andere Route projiziert, um dem verantwortlichen Lotsen das Mergen zweier Routen an einem Punkt zu erleichtern. Prinzipiell können zur Berechnung der Ghost-Label Positionen zwei unterschiedliche Verfahren angewandt werden: Das zeitbasierte und das abstandsbasierte Ghosting. Während das abstandsbasierte Ghosting bei regulären Arrivalrouten, bei dem zwei Anflugströme zusammengeführt werden, auf denen sich die Luftfahrzeuge mit dem gleichen standardisierten Anflugverfahren bewegen, problemlos im operationellen Betrieb eingesetzt werden kann, birgt die Zusammenführung von Anflugströmen mit unterschiedlichen Anflugverfahren noch nicht gelöste Probleme. Diese können teilweise gelöst werden, wenn ein zeitbasiertes „Two Segment Ghosting“ oder das erweiterte „Three Segment Ghosting“ mit dynamischen Anfluggeschwindigkeiten für die Ghost-Label eingesetzt wird. Als weitere optische Hilfe für eine zeitbasierte Führung von Luftfahrzeugen wird hier das Targeting vorgestellt, das im Rahmen von FAGI weiterentwickelt und auf die speziellen Fragestellungen des Projektes angepasst wurde.
Pseudointimal development on microporous polyurethane lattices. (1972)

A microporous polyurethane lattice has been used to line 8 and 11 mm. diameter knitfed Dacron grafts which were implanted into the canine infrarenal aorta and thoracic inferior vena cava. Similar grafts made from Dacron velour were used as control experiments. The surface of the lattice grafts were rapidly covered and healed into a stable collagen surface both in the aorta and vena cava. The majority of the velour grafts showed incomplete healing and significant thrombus deposition. Superior results obtained with the lattice grafts were thought to be related to the more complete incorporation of the pseudointimal layer into the lattice matrix. This produced a firm attachment of the initial fibrin layer which rapidly was transformed into collagen. The speed of coverage and the rapid transformation of the pseudointima into a stable collagen matrix probably accounts for the thrombus-resistant nature of this material and may explain its superiority to velour.

Abscisic acid determines arbuscule development and functionality in the tomato arbuscular mycorrhiza (2007)

The role of abscisic acid (ABA) during the establishment of the arbuscular mycorrhiza (AM) was studied using ABA sitiens tomato (Lycopersicon esculentum) mutants with reduced ABA concentrations. Sitiens plants and wild-type (WT) plants were colonized by Glomus intraradices. Trypan blue and alkaline phosphatase histochemical staining procedures were used to determine both root colonization and fungal efficiency. Exogenous ABA and silver thiosulfate (STS) were applied to establish the role of ABA and putative antagonistic cross-talk between ABA and ethylene during AM formation, respectively. Sitiens plants were less susceptible to the AM fungus than WT plants. Microscopic observations and arbuscule quantification showed differences in arbuscule morphology between WT and sitiens plants. Both ABA and STS increased susceptibility to the AM fungus in WT and sitiens plants. Fungal alkaline phosphate activity in sitiens mutants was completely restored by ABA application. * The results demonstrate that ABA contributes to the susceptibility of tomato to infection by AM fungi, and that it seems to play an important role in the development of the complete arbuscule and its functionality. Ethylene perception is crucial to AM regulation, and the impairment of mycorrhiza development in ABA-deficient plants is at least partly attributable to ethylene.
Improving Instruction of Programming Patterns with Faded Parsons Problems (2021)

Learning to recognize and apply programming patterns — reusable abstractions of code — is critical to becoming a proficient computer scientist. However, many introductory Computer Science courses do not teach patterns, in part because teaching these concepts requires significant curriculum changes. As an alternative, we explore how a novel user interface for practicing coding — Faded Parsons Problems — can support introductory Computer Science students in learning to apply programming patterns. We ran a classroom-based study with 237 students which found that Faded Parsons Problems, or rearranging and completing partially blank lines of code into a valid program, are an effective exercise interface for teaching programming patterns, significantly surpassing the performance of the more standard approaches of code writing and code tracing exercises. Faded Parsons Problems also improve overall code writing ability at a comparable level to code writing exercises, but are preferred by students.
Procedures as a Gateway to Spacecraft Autonomy. (2006)

This paper examines the role of procedures in operating crewed spacecraft and how procedures can serve as an entry point for spacecraft autonomy. Procedures repre-sent the knowledge necessary to operate a system and are a critical component of crewed spaceflight. Histor-ically, procedures have been executed by humans read-ing from a piece of paper or a static display. In this paper we describe a new procedure paradigm in which procedures are computer-understandable and can be executed by either humans or computers. This requires new procedure and system representations, develop-ment tools, autonomy software and displays. A pro-totype procedure development and execution system is described and applied to a space station procedure.
Constant Composition Study of Crystal Growth of Mixed Calcium-Ferrous Carbonate Salt (2010)

Abstract The formation of iron carbonate films, or by converting carbonate to magnetite at higher temperatures, are important means used to control the rate of corrosion in the oil and gas industry. The FeCO3 film can slow the corrosion process by covering up the steel surface and preventing the diffusion of corrosive species to the pipe surface. On the other hand, the excessive build up of iron carbonate salt in the oilfield production line can be a major issue, particularly, in the absence of effective inhibitors. The growth and thickness of the film depend upon the kinetics of precipitation and crystal growth of iron carbonate. In such kinetic studies, it is important to keep these parameters constant. This work was intended to study the kinetics of crystal growth of mixed calcium-ferrous carbonate salts at constant experimental conditions. In this study all the parameters are well controlled. A special experimental design is used to keep the initial concentrations, pH (7.1), temperature (31 and 48°C), pressure (1 atm), and ionic strength (0.5 M) constant during the course of the experiment. The composition of calcium-ferrous carbonate salt that formed was determined. The mass flux of crystal growth was also investigated and found to be constant.
Effects of Tensile Testing Temperature on Mechanical Properties and Deformation Behavior in Medium Mn Steels (2021)

In single-phase austenitic steels, the optimum deformation temperature in the tensile test to obtain high tensile strength-elongation balance (TS×El) and work hardening rate (dσ/dε) depends on control of the stability of austenite. In order to clarify the effects of the deformation temperature in complex phase steels containing austenite, in this study, the effects of the tensile testing temperature on mechanical properties and deformation behavior were investigated in detail using steel A and steel B with a chemical composition of 0.15C-0.5Si-5.0Mn (wt%). Steels A and B consisted of ferrite and retained austenite, but contained different volume fractions of retained austenite, namely, 29 % and 17 % as a result of annealing at 660 °C and 620 °C for 2 h, respectively. The stability of the retained austenite of steel B was higher than that of steel A. In steel A, TS×El and dσ/dε achieved their maximum values at 20 °C, decreased from 20 to 100 °C, and then remained almost unchanged at more than 150 °C. On the other hand, in steel B, TS×El and dσ/dε achieved their maximum values at -40 °C, decreased from -40 to 50 °C and remained almost unchanged at more than 100 °C. These results can be explained by the stability of retained austenite and the transformation rate from retained austenite to martensite. It should be noted that control of the stability of retained austenite and the transformation rate from retained austenite to martensite led to an adjustment of the optimum deformation temperature to achieve the high TS×El and dσ/dε in medium Mn steels, in the same manner as in single-phase austenitic steels.
Interval-based real-time transmission control (2002)

Existing cell switched and packet switched transmission systems have difficulties to support real-time data transfer because the queueing characteristics and load variations in the network nodes are a handicap for it. With our interval-based output buffer transmission control method the data stream behavior is regulated in each network node and a data stream dependent time parameter adjustment is performed in each control process. The interval-based control method is also adjustable for controlling data stream smoothing and compression processes in a source node.
