Analysis of Steering Knuckle of All Terrain Vehicles (ATV) Using Finite Element Analysis (2016)

Steering knuckle is the most stress sustaining and critical component of All Terrain Vehicle (ATV). Steering knuckle is the pivot point of the steering and suspension system, which allows the front wheels to turn and also allow the movement of suspension arms motion. The light weight and high strength component is always in demanding for racecar application. Lightweight and optimized design of steering knuckle is proposed to use for a BAJA SAE INDIA off road racecar. Due to the failure in knuckle in terrain vehicle after some instances, it has to be modified for better performance. The 3D CAD model created by using CATIA V5 and static as well as model analysis carried out in ANSYS 12 to understand its behavior under operating conditions. All test for frame was carried out on aluminum alloys 6061-T6 & for spindle EN8. The paper discusses the FE analysis of existing and modified Steering Knuckle.
A Hierarchical Carbon Derived from Sponge‐Templated Activation of Graphene Oxide for High‐Performance Supercapacitor Electrodes (2016)

A hierarchical porous carbon is fabricated by introducing a polyurethane sponge to a template graphene oxide into a 3D interconnected structure, while KOH activation generates abundant micropores in its backbone. Supercapacitors assembled with this carbon achieve a high energy density of 89 W h kg(-1) (64 W h L(-1) ) and outstanding power density due to the shortened ion-transport distance in 3D.
Real area-power-delay trade-off in EUCLID logic synthesis system (2002)

The EUCLID logic synthesis system, in which true area-power-delay trade-off is possible, is described. To achieve this, area, delay, and power consumption are estimated at every stage of the process, and optimization decisions taken accordingly. Optimal gate-sizing fine tunes the delay of the circuit, EUCLID provides a framework to explore the area-delay-power design space for a given circuit, giving the designer an optimal implementation based on design needs. Currently, EUCLID is able to handle circuits of several thousands of transistors, with each tool running in a few minutes. Smaller circuits, with smaller hundreds of transistors, only take seconds to run.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
ARMA order selection for EEG-an empirical comparison of three order selection algorithms (2003)

The performance of three ARMA (autoregressive moving-average) order estimation algorithms, canonical correlation analysis, S-array, and Franke algorithm, on simulated and real electroencephalogram (EEG) signals is presented. It is shown that the S-array always correctly indicates the AR order but makes incorrect estimates of the MA order. The canonical correlation method identifies the model order correctly for simulated data and overestimates the AR order on real data. The Franke algorithm is shown to perform poorly in comparison to the other algorithms.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Factors influencing the presence of faecal lactobacilli in early infancy. (1990)

The faecal flora of 46 preterm infants and 52 born at full term was studied at 10 days of age; 46 born at full term and 37 preterm infants were also studied at 30 days. Viable counts of coliforms, lactobacilli, and bifidobacteria were made; gas liquid chromatography was used to identify the anaerobes. Lactobacilli, but not bifidobacteria, were found in high counts in the stools of most of the infants born at full term by 30 days of age. The mode of delivery, but not the method of feeding, had a significant influence on early colonisation. A selective deficiency of lactobacilli compared with coliform organisms was found in preterm infants. Previous treatment with antibiotics and being nursed in an incubator were also significantly associated with a lower rate of early colonisation with lactobacilli. Our findings indicate that lactobacilli may be an important part of the normal stool flora in early infancy, and that modern methods of neonatal care are associated with delayed or deficient colonisation.

A Novel Single-Phase Adaptive Reclosure Scheme for Transmission Lines With Shunt Reactors (2009)

Single-phase adaptive reclosure (SPAR) schemes applied to transmission lines have been an effective method to improve the stability of power system. Attractive techniques have been proposed for SPAR schemes based on the tripped fault-phase voltage. But for transmission lines with shunt reactors, the voltage is so minor that the error of voltage transformer limits the applications of voltage-based SPAR schemes. To overcome this disadvantage, a new scheme using differential current between the calculated current based on transient fault model and the actual measured current from the fault phase of shunt reactor is proposed in this paper. The calculated current is obtained by using the transient fault model whether there is a transient or permanent fault. In the case of transient fault, the calculated current is close to the measured current due to the actual fault model being close to the calculated model. As for the permanent fault, the calculated current is quite different from the measured current. Therefore, the differential current of the fault phase can be employed to distinguish permanent fault from transient fault. At last, the Alternative Transients Program simulation results show that the developed algorithm can identify the permanent fault correctly and reliably, and is promised to be applied to SPAR for transmission lines with shunt reactors.

Time-Based Digital LDO Regualtor with Fractionally Controlled Power Transistor Strength and Fast Transient Response (2019)

The number of enabled power transistors and their ON-time of a digital low-dropout (LDO) regulator are controlled by a time-based controller. By the time-based controller consisting of two voltage-controlled oscillators (VCO) and a phase-detecting switch driver, the effective number of enabled power transistors and therefore their strength can be fractionally controlled. The transient response is greatly improved by a transient detector which selectively disables one of the two VCOs during a transient condition. At steady state, the number of switching power transistor is either zero or one, minimizing the ripple of the output voltage. Implemented in a 65 nm CMOS technology, the time-based digital LDO regulator can provide 0.5 ~ 1.1V output from 0.9 ~ 1.2V input. For the maximum load current of 19 mA, the peak current efficiency is 99.3 %. For both the step-up and -down changes of the load current by 3 mA, the voltage level of the output is stabilized in less than 90 ns.

The paper also focuses on the ways in which the technology is used by firms and advertisers to give customers a better user experience. AR is a growing field with a lot of scope in the future, the paper also gives an insight on what is in store for AR in the near future.
A Multiple Watermarking Algorithm for Texts Mixed Chinese and English (2013)

Digital watermarking is a common digital product copyright protection mechanism, and used widely in information security research area. But there are still some deficiencies in current digital text watermarking algorithm, such as low robustness, insufficient security, low watermarking capacity and inability of application to texts mixed Chinese and English. The paper proposes a multiple watermarking algorithm for texts mixed Chinese and English based on character encoding and attributes. This algorithm can provide a larger watermarking capacity, and meanwhile keep the watermarking information invisible. And then it also provides strong security and auto error correction ability to guarantee that the watermarking is not destroyed or tampered by other malicious attackers. Our experiment and related analysis demonstrate all these features.
Chemical Probes for the Recognition of Cannabinoid Receptors in Native Systems (2012)

Receptors made visible: The described biotin-tagged small-molecule probes with excellent affinities for the CB(1) and CB(2) cannabinoid receptors (CB(1)R and CB(2)R) enable direct visualization of these receptors in native cellular systems, including neurons, microglia, and immune cells. This method could overcome some of the limitations of current methodologies and may help to dissect the complexity of the endogenous cannabinoid system.
Artificial Metalloenzymes for Enantioselective Catalysis Based on the Noncovalent Incorporation of Organometallic Moieties in a Host Protein (2005)

Enzymatic and homogeneous catalysis offer complementary means to produce enantiopure products. Incorporation of achiral, biotinylated aminodiphosphine-rhodium complexes in (strept)avidin affords enantioselective hydrogenation catalysts. A combined chemogenetic procedure allows the optimization of the activity and the selectivity of such artificial metalloenzymes: the reduction of acetamidoacrylate proceeds to produce N-acetamidoalanine in either 96 % ee (R) or 80 % ee (S). In addition to providing a chiral second coordination sphere and, thus, selectivity to the catalyst, the phenomenon of protein-accelerated catalysis (e.g., increased activity) was unraveled. Such artificial metalloenzymes based on the biotin-avidin technology display features that are reminiscent of both homogeneous and of enzymatic catalysis.
Phosphorylation Controls the Three-dimensional Structure of Plant Light Harvesting Complex II (1997)

The most abundant chlorophyll-binding complex in plants is the intrinsic membrane protein light-harvesting complex II (LHC II). LHC II acts as a light-harvesting antenna and has an important role in the distribution of absorbed energy between the two photosystems of photosynthesis. We used spectroscopic techniques to study a synthetic peptide with identical sequence to the LHC IIb N terminus found in pea, with and without the phosphorylated Thr at the 5th amino acid residue, and to study both forms of the native full-length protein. Our results show that the N terminus of LHC II changes structure upon phosphorylation and that the structural change resembles that of rabbit glycogen phosphorylase, one of the few phosphoproteins where both phosphorylated and non-phosphorylated structures have been solved. Our results indicate that phosphorylation of membrane proteins may regulate their function through structural protein-protein interactions in surface-exposed domains.
Micro power management of active 802.11 interfaces (2008)

Wireless interfaces are major power consumers on mobile systems. Considerable research has improved the energy efficiency of elongated idle periods or created more elongated idle periods in wireless interfaces, often requiring cooperation from applications or the network infrastructure. With increasing wireless mobile data, it has become critical to improve the energy efficiency of active wireless interfaces. In this work, we present micro power management (μPM), a solution inspired by the mismatch between the high performance of state-of-the-art 802.11 interfaces and the modest data rate requirements by many popular network applications. μPM enables an 802.11 interface to enter unreachable power-saving modes even between MAC frames, without noticeable impact on the traffic flow. To control data loss, μPM leverages the retransmission mechanism in 802.11 and controls frame delay to adapt to demanded network throughput with minimal cooperation from the access point. Based on a theoretical framework, we employ simulation to systematically investigate an effective and efficient implementation of μPM. We have built a prototype μPM on an open-access wireless hardware platform. Measurements show that more than 30% power reduction for the wireless transceiver can be achieved with μPM for various applications without perceptible quality degradation.
Multilevel data communication over optical fibre (1991)

An investigation of the characteristics of several multilevel ‘alphabetic’ line codes of type ‘mBn_X’ is described. Multilevel codeclasses which used two dictionaries and up to five (‘mBn_5’) different symbols were considered. A total of thirteen different optical fibre communication systems were designed. The extra power budget, transmission efficiency, hardware complexity, and end-to-end delays of multilevel alphabetic line coders were compared with binary and ‘linear’ line coders. A data communication simulator was built called SIMALCODE: simulator for alphabetic line coding and decoding. This allowed examination of the required type of line coder in terms of timing extraction, error detection strategies and the buffering for the required data reliability. A ‘codeset’ could be selected from many of these codeclasses in billions of ways and multilevel coding theory is required to select the most appropriate.
Topiramate Serum Concentration-to-Dose Ratio (2004)

The influence of age and concomitant antiepileptic drugs (AEDs) on the trough steady-state serum concentration of topiramate, normalized to 1 mg/kg body weight or concentration-to-dose ratio (TPM-CDR), was assessed using multivariate methods in samples from 94 epileptic patients (38 under 11 years and 56 over 11 years of age), most of whom were outpatients receiving either just TPM (n = 20) or TPM in combination with other AEDs (n = 74). Analysis of the covariance showed that the age of the patients was influential (P < 0.001) and also showed a difference in TPM-CDR between the non-inducers group (TPM or TPM + lamotrigine or valproate) and the inducers group (TPM + carbamazepine, phenobarbital, or phenytoin) (P < 0.001). The TPM-CDR was 0.4 +/- 0.1 in patients under 11 years with inducers (n = 7), 0.8 +/- 0.3 in patients over 11 years with inducers (n = 32), 1.1 +/- 0.4 in patients under 11 years with noninducers (n = 30), and 1.8 +/- 0.6 in patients over 11 years with noninducers (n = 21). A two-way analysis of the variance showed differences between patients under 11 years and those over 11 years (P < 0.001), and between the noninducers and inducers groups (P < 0.001). TPM-CDR was nearly 50% lower in patients under 11 years than in patients over 11 years, and in patients with TPM + inducers than in patients with TPM or TPM + noninducers, in both children and adults. To achieve the same serum concentration of TPM, children will need double the daily dose per kilogram of TPM required by adults, and both children and adults taking enzyme-inducing AEDs will require double the dose needed by those who do not take them.
Efficient implementation and processing of a real-time panorama video pipeline with emphasis on dynamic stitching (2013)

The Bagadus system has been introduced as an automated tool for soccer analysis, and it is built up by an analysis subsystem, tracking subsystem and video subsystem. Bagadus allows for simplified soccer analysis, with the goal of improving athletes' performance, by automating the integration of these subsystems. The system is currently installed at Alfheim stadium in Tromsø, Norway. An important part of the video subsystem is the creation of panorama videos from four HD cameras. However, the stitching pipeline for panorama video generation in the first version of the system did not manage to do this in real-time.\n\nIn this thesis, we present how to build an improved panorama stitcher pipeline that is able to stitch video from four HD cameras into a panorama video in real-time. We will detail the architecture and modules of this pipeline, and analyze the performance. In addition we will focus on the stitching component, and how that can improve the overall visual quality of the output panorama.

A cost effective fermentative production of glutathione by Saccharomyces cerevisiae with cane molasses and glycerol (2013)

This work aimed to evaluate the effect of sugar cane molasses and glycerol on glutathione (GSH) fermentation by Saccharomyces cerevisiae ATCC 7754 in flask culture using response surface methodology. Under optimized conditions (80 g/L of molasses and 60 g/L of glycerol), the highest GSH and biomass concentration achieved were 119.6 mg/L and 25.3 g/L, respectively. Further studies done in 5 L bioreactor resulted 241.3 mg/L GSH after 96 h in batch fermentation without amino acids addition and the concentration of biomass was 12.1 g/L. In batch fermentation with the addition of the three amino acids (4 mM cysteine, glycine and glutamic acid at 32 h), biomass reached to 25 g/L and GSH, 236.1 mg/L at 96 h of fermentation. The strategy of precursor amino acids addition is a key aspect in increasing the synthesis of GSH.
Dynamic label binding at run-time (2003)

Information flow control allows enforcement of end-to-end confidentiality policies but has been difficult to put in practice. This paper introduces a pragmatic new approach for tracking information flow while the process is running at the same time applying dynamic label binding. The underlying implementation mechanism uses machine code instruction stream modification to track individual data movements and manipulations within the address space of an application. This gives the ability to precisely determine all information flow causing operations and apply controls that do not overly restrict what computations can be performed.
Molekulargewichtsbestimmung von polyvinylpyrrolidonen (PVP) mittels des osmotischen drucks und der lichtstreuung ihrer lösungen (1952)

Abstract Bei der Bestimmung des Molekulargewichts von PVP‐Fraktionen mittels des osmotischen Drucks erhält man Werte, die die in der vorausgehenden Arbeit von Scholtan Angegebenen Formeln im Molekulargewichtsbereich von 10 000 bis 100 000 bestätigen. Für PVP mit höherem Molekulargewicht werden allerdings infolge der Uneinheitlichkeit der Fraktionen zu kleine Werte gefunden. Für unfraktionierte Produkte gilt für die Berechnung des Zahlenmittels des Molekulargewichts aus den k‐Werten nach Fikentscher die Näberungsformel M̄ n = 24 k 2 . Die Prüfung der verwendeten Membranen auf ihre Durchlässigkeit für PVP‐Moleküle ergibt, daß nur für M ≦ 10 000 mit einer nicht zu vernachlässigenden Diffustion zu rechnen ist. Die aus den Lichstreuungsmessungen ermittelten Molekulargewichte stimmen bei der Wahl einer PVP‐Fraktion als Standardsubstanz ziemlich gut mit den aus den Ultrazentrifugen‐Messungen ermittelten Werten überein. Sie bestätigen insbesondere die von Scholtan angegebene Formel auch für höhere Molekulargewichte. Aus der vom Rayleighschen Gesetz abweichenden Wellenlängenabhängigkeit der Streuintensitäten für 2 Höhere molekulare PVP wird unter Annahme eines Kuhnschen Knäuelmodells der statistische Abstand der Molekülenden, also der angenäherte Knäueldurchmesser, für M = 249 000 zu 360 Å und für M = 1 116 000 zu etwa 930 Å ermittelt. Die PVP‐Moleküle sind in Wäßriger Lösung also start geknäuelt.
A bifunctional enzyme, with separate xylanase and beta(1,3-1,4)-glucanase domains, encoded by the xynD gene of Ruminococcus flavefaciens (1993)

Adjacent regions of a Ruminococcus flavefaciens 17 DNA fragment were found to encode xylanase and beta(1,3-1,4)-glucanase activities. Sequencing of this fragment showed that both activities are encoded by a single 2,406-bp open reading frame corresponding to the xynD gene. The predicted product has a characteristic signal sequence that is followed by an amino-terminal domain related to family G xylanases, while the carboxyterminal domain is related to beta(1,3-1,4)-glucanases from several other bacterial species. These two domains are connected by a region of unknown function that consists of 309 amino acids and includes a 30-amino-acid threonine-rich sequence. A polypeptide having a molecular weight of approximately 90,000 and exhibiting xylanase and beta(1,3-1,4)-glucanase activities was detected in Escherichia coli cells carrying the cloned xynD gene. This is one of the first cases in which a microbial polysaccharidase has been shown to carry separate catalytic domains active against different plant cell wall polysaccharides within the same polypeptide. xynD is one of a family of related genes in R. flavefaciens that encode enzymes having multiple catalytic domains, and the amino terminus of XYLD exhibits a high degree of similarity with the corresponding regions of another xylanase, XYLA, which carries two different xylanase catalytic domains.
Neutron Scattering Investigation of the Magnetic Excitations in CoBr<sub>2</sub> (1980)

In order to investigate the two-dimensionality and the easy plane anisotropy, the spin waves propagating along the [h, 0, 0], [h, h, 0], [h, 0.5h, 0] and [0, 0, l ] directions in CoBr 2 were observed using inelastic neutron scattering technique. The spin dynamics of CoBr 2 can be described by the anisotropic exchange Hamiltonian for S =1/2 with intraplanar exchange constants J 1 =2.01 meV, J 2 =0.019 meV and J 3 =-0.338 meV, interplanar exchange J '=-0.97 meV, and planar anisotropies D 1 =1.14 meV and D '=-0.06 meV. As shown by these numerical values, CoBr 2 has fairly strong XY characters, but the two-dimensionality is definitely poor. We point out, however, that in a planar antiferromagnet, the easy plane type anisotropy should remove the degeneracy of the excitation spectrum for the `in-plane' and the `out-of-plane' correlations, and in fact, these excitations are observed separately in this experiment.
