Facial Recognition using Convolutional Neural Networks and Implementation on Smart Glasses (2019)

Facial Recognition possess the importance to give biometric authentication that is used in different applications especially in security. A stored database of the subjects is manipulated using image processing techniques to accomplish this task. This paper proposes a frame work of smart glasses that can recognize the faces. Implementing facial recognition using portable smart glasses can aid law enforcement agencies to detect a suspect’s face. The advantage over security cameras is their portability and good frontal view capturing. The techniques used for the whole process of face recognition are machine learning based because of their high accuracy as compared with other techniques. Face detection is the pre-step for face recognition that is performed using Haar-like features. Detection rate of this method is 98% using 3099 features. Face recognition is achieved using Deep Learning’s sub-field that is Convolutional Neural Network (CNN). It is a multi-layer network trained to perform a specific task using classification. Transfer learning of a trained CNN model that is AlexNet is done for face recognition. It has an accuracy of 98.5% using 2500 variant images in a class. These smart glasses can serve in the security domain for the authentication process.
Synthesis of 1,3,4,5‐Tetrahydro‐2‐benzoxepin Derivatives as Conformationally Restricted Analogues of cyclamenaldehyde‐type compounds and as intermediates for highly odour‐active homologues (1996)

Abstract Nine 1,3,4,5‐tetrahydro‐2‐benzoxepin derivatives have been prepared as mimics of the folded ( gauche ) conformation of cyclamenaldehyde ( 1 ) and related compounds, but none of them showed the typical lily‐of‐the valley (muguet) odour activity. However, conversion of these substances to previously unknown analogues of 1 having a Me substituent on the aromatic ring in an ortho position to the side chain led to new fragrance substances with remarkable properties. The results indicate that the extended ( anti ) conformation is more likely to be the ‘bioactive’ one at the receptor site(s).
Electrical performance of spirally wound ion LiMn/sub 2/O/sub 4/ spinel cells (2002)

The lithium ion battery with manganese spinel cathode is attractive for an EV (electric vehicle) as well as consumer cells due to lower materials cost. A spirally wound 4/3 A size cell was developed to test materials for use in portable and EV batteries. The 4/3 A size is a convenient development vehicle since it is economical of materials but allows meaningful energy density, cycle life and stability estimates. Initial cells had high power capabilities with 85% capacity retention at 2 C, demonstrating the high power capability of the ion spinel system. Energy densities were 220 Wh/l and 84 Wh/kg for the complete cell. This significant improvement in battery characteristics due to the improved spinel material in an unoptimized cell now makes the ion spinel cell a promising candidate for both consumer and EV applications.
Visualization of users' activities in a specific environment (2007)

Evaluation of user interface design is usually based on usability testing methods. In this paper we analyzed and described the user behavior in the form of the user model. The user model is built on a data set which was acquired through observation of user behavior. The criterion we use for the evaluation of the usability of interface design is the user cognitive load. We present different tools for visualization, simulation and easier analysis of the user model. Because each of the methods and tools presented use only part of the user model, in the end we present methods on how to use the complete user model to correctly describe user behavior. In order to understand such a complex model we need to have a proper visualization tool. The concept of such a visualization tool is presented at the end of this paper.
A High-Speed CMOS Integrated Optical Receiver With an Under-Damped TIA (2015)

We present a CMOS integrated optical receiver having under-damped transimpedance amplifier (TIA) and CMOS avalanche photodetector (APD) realized in 65-nm CMOS technology. The under-damped TIA compensates the bandwidth limitation of CMOS APD and provides enhanced receiver bandwidth performance with reduced power consumption and better sensitivity compared with previously reported techniques. We successfully demonstrate 10-Gb/s 231-1 PRBS and 12.5-Gb/s 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">7</sup> -1 PRBS operation with the bit-error rate less than 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-12</sup> at the incident optical power of -6 and -2 dBm, respectively. The receiver has core size of 0.24 mm × 0.1 mm and power consumption excluding output buffer of -.13.7 mW with 1.2 V supply voltage.
Microplasmin: A Novel Thrombolytic That Improves Behavioral Outcome After Embolic Strokes in Rabbits (2002)

The present study shows that microplasmin improves behavioral rating scores in the RSCEM when administered 60 minutes after embolization, at a dose that does not increase hemorrhages in the RLCEM. This is in contrast to tPA, which significantly enhances the hemorrhage rate in the RLCEM.
Switched fragmented aperture antennas (2002)

This paper introduces a reconfigurable aperture concept derived from fragmented aperture design where the configuration of the fragmented aperture may be switched by the user to obtain different functionalities. A fragmented aperture antenna is a patchwork of discrete conducting and dielectric units distributed over the specified aperture. The arrangement of the units is determined using an efficient, multistage procedure that incorporates the genetic algorithm for optimization and the finite-difference time-domain method for the electromagnetic computation. Typically, the criterion for optimum performance has been broadband gain at a particular angle. The resulting antennas contain isolated scattering structures that are fragmented in appearance.
Energy storage options for space power (1985)

Including energy storage in a space power supply enhances the feasibility of using thermal power cycles (Rankine or Brayton) and providing high-power pulses. Review of storage options (superconducting magnets, capacitors, electrochemical batteries, thermal phase-change materials (PCM), and flywheels) suggests that flywheels and phase-change devices hold the most promise. Latent heat storage using inorganic salts and metallic eutectics offers thermal energy storage densities of 1500 to 2000 kJ/kg at temperatures to 1675/sup 0/K. Innovative techniques allow these media to operate in direct contact with the heat engine working fluid. Enhancing thermal conductivity and/or modifying PCM crystallization habit provide other options. Flywheels of low-strain graphite and Kevlar fibers have achieved mechanical energy storage densities of 300 kJ/kg. With high-strain graphite fibers, storage densities appropriate to space power needs (approx. 550 kJ/kg) seem feasible. Coupling advanced flywheels with emerging high power density homopolar generators and compulsators could result in electric pulse-power storage modules of significantly higher energy density.
Remote control of catheter tip deflection: An opportunity for interventional MRI (2002)

This study seeks to exploit the high magnetic field environment of a clinical MRI scanner and demonstrate the technical feasibility of developing a catheter whose tip can be remotely oriented within the magnetic field by applying a DC current to a coil wound around the catheter tip to generate a magnetic moment and consequent deflection. To achieve arbitrary three-dimensional deflections, a three-axis coil was wound on a 1.5 Fr cylindrical catheter. By applying DC currents in the 100 mA range, this catheter was successfully guided through a 3D phantom maze, mimicking the vasculature, under MR imaging guidance. Feasibility was demonstrated that the strong ambient magnetic field of the MR scanner offers a special opportunity to develop simple devices that can be remotely steered to sites of clinical interest.

High resolution x-ray powder diffraction measurements on poled PbZr1-xTixO3 (PZT) ceramic samples close to the rhombohedral-tetragonal phase boundary (the so-called morphotropic phase boundary) have shown that for both rhombohedral and tetragonal compositions the piezoelectric elongation of the unit cell does not occur along the polar directions but along those directions associated with the monoclinic distortion. This work provides the first direct evidence for the origin of the very high piezoelectricity in PZT.
<scp>I</scp>. Yeast sequencing reports. Isolation and characterization of the <i>LEU2</i> gene of <i>Hansenula polymorpha</i> (1994)

A DNA fragment carrying the LEU2 gene of methylotrophic yeast Hansenula polymorpha was isolated by complementation of the leuB mutation of Escherichia coli. The nucleotide sequence of the isolated DNA fragment contains an open reading frame of 363 codons, coding for a protein 80% identical to the LEU2 gene product of Saccharomyces cerevisiae. Further downstream, there is a partial reading frame with no obvious similarity to known proteins. The LEU2 gene of H. polymorpha cannot complement the leu2 mutation of S. cerevisiae.
Structural Analysis of a Fiber-Pseudotyped Adenovirus with Ocular Tropism Suggests Differential Modes of Cell Receptor Interactions (2001)

Adenovirus (Ad) entry into cells is initiated by the binding of the fiber knob to a cell surface receptor. The coxsackie- and adenovirus receptor (CAR) functions as the attachment receptor for many, but not all, Ad serotypes. Ad type 37 (Ad37), a subgroup D virus that causes keratoconjunctivitis in humans, does not infect cells via CAR despite demonstrated binding of the Ad37 knob to CAR. We have pseudotyped a fiber deletion Ad5 vector with the Ad37 fiber (Ad37f), and this vector retains the ocular tropism of Ad37. Here we present a cryo-electron microscopy reconstruction of Ad37f that shows the entire Ad37 fiber, including the shaft and knob domains. We have previously proposed that Ad37 may not utilize CAR for cell entry because of the geometric constraints imposed by a rigid fiber (E. Wu, J. Fernandez, S. K. Fleck, D. Von Seggern, S. Huang, and G. R. Nemerow, Virology 279:78-89, 2001). Consistent with this hypothesis, our structural results show that the Ad37 fiber is straight and rigid. Modeling of the interaction between Ad37f and host cell receptors indicates that fiber flexibility or rigidity, as well as length, can affect receptor usage and cellular tropism.
Generating lane level road data from vehicle trajectories using Kernel Density Estimation (2013)

An informative digital map is a prerequisite for future Intelligent Transportation System (ITS) applications such as lane level navigation systems. Preparing and updating such detailed digital maps by using existing methods such as surveying and image digitization is not practical due to the time and cost involved. We propose a method that statistically mines Global Positioning System (GPS) trajectory data obtained from vehicles to generate a lane level digital map of the road. The proposed method is capable of generating a digital map of the road which contains lane centerlines. The proposed method is independent of the lane width, lane parallelism and can handle lane splits and merges. In addition, a method that can be used to generate a map of lane boundaries is also presented. The proposed methods have been tested using the GPS data collected using vehicles equipped with GPS enabled mobile phones. Results show that the proposed method for lane centerline generation is successful in different road geometries.
Stability of the synthesis filter in stereo linear prediction (2004)

A scheme for stereo audio coding is proposed consisting of a 2-channel linear prediction stage in combination with a single rotator. It is argued that it combines different attractive features of existing stereo coding mechanisms. It is experimentally shown that for unequal orders of auto- and cross-predictors, the stability of the synthesis system cannot always be guaranteed. For equal orders, the Block-Levinson algorithm is applicable, which is the basis for the proof of the stability of the synthesis filter. It is shown that the forward and the\nbackward error signal vectors appearing in a 2-channel lattice filter implementation are coupled via a 2-channel allpass filter. This latter finding can be used as the basis for an alternative proof of the stability of the synthesis system.
New polymer syntheses. 60. Thermostable polymers of 2‐(hydroxyaryl)benzoxazole‐5‐carboxylic acids (1991)

Abstract Tristrimethylsilyl‐3‐amino‐4‐hydroxybenzoic acid was condensed with various aromatic acetoxy carboxylic acid chlorides in Marlotherms‐S® at 20–350°C. Under these conditions formation of an amide group, ring closure to benzoxazole groups and polycondensation occur step by step in a “one‐pot procedure”. The crude polyesters were hydrolyzed to yield pure 2‐(hydroxyaryl) benzoxazole‐5‐carboxylic acids which were acetylated and polycondensed. The pure polyesters obtained in this way were characterized by viscosity and DSC measurements, WAXS‐powder patterns, and thermogravimetric analyses. The polyester of 2‐(4‐hydrophenyl) benzoxazole‐5‐carboxylic acid has a degree of crystallinity &gt; 90% and a short term in thermostability in air up to 500°C.
Truncated backpropagation through time and Kalman filter training for neurocontrol (2002)

We have recently established the feasibility of training recurrent neural networks by parameter-based decoupled extended Kalman filter (DEKF) algorithms for control of nonlinear dynamical systems. In this paper we investigate the use of truncated backpropagation through time (BPTT) for approximating the required dynamic derivatives that are used by the DEKF training algorithm. The use of this approximation allows the gradient calculations and weight updates by the DEKF algorithm to be performed asynchronously with application of control signals, thereby leading to a scalable, real-time, online training algorithm. We demonstrate in simulation the effectiveness of the BPTT-based DEKF algorithm for the problem of automotive engine idle speed control.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
The effect of postprandial changes in pH along the gastrointestinal tract on the distribution of ions between the solid and fluid phases of chyme in rainbow trout (2008)

An area of emerging importance is the role that the diet can play in alleviating the demands for ion uptake in fish living in a freshwater environment, by providing a highly concentrated supply of electrolytes. The availability of ions for uptake from the diet likely requires dissolution in the fluid phase of the chyme. However, the distribution of ions between the fluid and solid phases of chyme has not been well-characterized in fish, and little is known about the effects of location along the gastrointestinal (GI) tract, or about the pH gradients found therein, on this distribution. Hence, the pH and ionic concentrations (Na+, K+, Cl−, Ca2+ and Mg2+, in both fluid and solid phases) of the chyme in each GI tract section were measured at various time points during the digestion of a single meal of commercial pellets in freshwater rainbow trout (Oncorhynchus mykiss). Additionally, the presence of an inert reference marker (lead-glass beads) in the diet was used to quantify the distribution of these ions between the solid and fluid phases of the chyme. The buffering capacity of the food was evident in the acidic stomach (ST), whereas the intestine provided an alkaline environment for further digestion. It appeared that pH had little influence on the distribution of the monovalent ions between the phases in all GI tract sections. However, the ST showed significant changes in the partitioning of both Ca2+ and Mg2+, with each mineral becoming highly dissolved as the gastric chyme pH decreased. This was followed by subsequent precipitation of both minerals in the alkaline environment of the intestine. The high degree of dissolution of Ca2+ and Mg2+ in the fluid phase of gastric chyme corresponded with large absorptive rates from the ST seen previously, however, this was not true of the monovalent ions.
Smart non-default routing for clock power reduction (2013)

At advanced process nodes, non-default routing rules (NDRs) are integral to clock network synthesis methodologies. NDRs apply wider wire widths and spacings to address electromigration constraints, and to reduce parasitic and delay variations. However, wider wires result in larger driven capacitance and dynamic power. In this work, we quantify the potential for capacitance and power reduction through the application of "smart" NDR (SNDR) that substitute narrower-width NDRs on selected clock network segments, while maintaining skew, slew, delay and EM reliability criteria. We propose a practical methodology to apply smart NDRs in standard clock tree synthesis flows. Our studies with a 32/28nm library and open-source benchmarks confirm substantial (average of 9.2%) clock wire capacitance reduction and an average of 4.9% clock switching power savings over the current fixed-NDR methodology, without loss of QoR in the clock distribution.
Towards a large-scale recording system: Demonstration of polymer-based penetrating array for chronic neural recording (2014)

The brain is a massively interconnected network of specialized circuits. Even primary sensory areas, once thought to support relatively simple, feed-forward processing, are now known to be parts of complex feedback circuits. All brain functions depend on millisecond timescale interactions across these brain networks. Current approaches cannot measure or manipulate such large-scale interactions. Here we demonstrate that polymer-based, penetrating, micro-electrode arrays can provide high quality neural recordings from awake, behaving animals over periods of months. Our results indicate that polymer electrodes are a viable substrate for the development of systems that can record from thousands of channels across months to years. This is our first step towards developing a 1000+ electrode system capable of providing high-quality, long-term neural recordings.
PICQUERY: a high level query language for pictorial database management (1988)

A reasonably comprehensive set of data accessing and manipulation operations that should be supported by a generalized pictorial database management system (PDBMS) is proposed. A corresponding high-level query language, PICQUERY, is presented and illustrated through examples. PICQUERY has been designed with a flavor similar to QBE as the highly nonprocedural and conservational language for the pictorial database management system PICDMS. PICQUERY and a relational QBE-like language would form the language by which a user could access conventional relational databases and at the same time pictorial databases managed by PICDMS or other robust PDBMS. This language interface is part of an architecture aimed toward data heterogeneity transparency over pictorial and nonpictorial databases.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Bark scale equalizer design using warped filter (2002)

Bark scale (also called critical band rate in the literature) has attracted increasing attention among audio engineers as a good measurement of the frequency resolving ability of the human auditory system. The warped filter technique has been applied to the Bark scale to construct an equalizer for a low-cost loudspeaker system. In a simulation, the resulting equalizer displays an overall better equalization effect than the conventional deconvolution-based equalizer.
Design and Development of a Low Speed High Torque Hydraulic Motor (1981)

&lt;div class="htmlview paragraph"&gt;A low speed, high torque hydraulic motor has been developed. This motor utilizes radial pistons with roller cam followers, a fixed cam and a rotating piston carrier splined to the output shaft. Oil routing is accomplished by a non-rotating manifold with lapped porting faces. A destroke device is provided which hydraulically retracts the pistons for disengaged operation.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Mounting is accomplished through a high pressure pivot joint to allow the motor to be used for powered steerable wheels.&lt;/div&gt;
The Role of the Side Chain in Determining Relative δ- and κ-Affinity in C5‘-Substituted Analogues of Naltrindole (2002)

The role of the side chain in 5'-substituted analogues of naltrindole has been further explored with the synthesis of series of amides, amidines, and ureas. Amidines (8, 13) had greatest selectivity for the kappa receptor, as predicted from consideration of the message-address concept. It was also found that an appropriately located carbonyl group, in ureas (10) and amides (7), led to retention of affinity and antagonist potency at the delta receptor.
Effect of Ibudilast, a Novel Antiasthmatic Agent, on Anaphylactic Bronchoconstriction: Predominant Involvement of Endogenous Slow Reacting Substance of Anaphylaxis (1993)

The effect of ibudilast on anaphylactic bronchoconstriction was studied in guinea pigs sensitized actively with ovalbumin (OA). Animals were treated with indomethacin, tripelennamine and propranolol prior to the antigen challenge. Anaphylactic bronchoconstriction was prevented by ibudilast (1-4 mg/kg i.v. and 5-20 mg/kg p.o.) dose-dependently. FPL55712 and phenidone were also effective. Even when administered at the maximum development of bronchoconstriction, ibudilast (0.5 and 2 mg/kg i.v.) and FPL 55712 caused significant reduction of the increased airway tone, while phenidone did not. Ibudilast (1-4 mg/kg i.v.) and FPL55712 inhibited leukotriene D4-induced airway responses in nonsensitized guinea pigs pretreated with indomethacin and propranolol. Ibudilast (1.6 and 4 mg/kg i.v.) inhibited platelet-activating-factor (PAF)-induced airway responses in nonsensitized guinea pigs pretreated with indomethacin and propranolol, however, FPL 55712 inhibited PAF-induced airway responses only at a high dose such as 10 mg/kg i.v. Ibudilast (4 mg/kg i.v.) did not inhibit acetylcholine-induced airway response. Ibudilast showed inhibition of the release of slow-reacting substance of anaphylaxis (SRS-A) from guinea pig chopped lung sensitized with OA, which was significantly diminished by indomethacin. The drug little affected the activity of phospholipase A2 and 5-lipoxygenase in guinea pig polymorphonuclear leukocytes. These results indicate that ibudilast inhibits anaphylactic bronchoconstriction which is considered to be largely mediated by endogenously released SRS-A. The inhibitory effect of ibudilast on anaphylactic bronchoconstriction in the presence of indomethacin is considered to be exerted through its antagonism to SRS-A.
