3D Fashion Fast Modeling from Photographs (2009)

The paper presents a technique of 3D fashion modeling from photographs of wearing clothes in front and back views. Firstly, an efficient segmentation method is applied on photographs to obtain the silhouette of the fashion. Then, a template-based feature extraction algorithm is introduced to determine the feature points on the garment. Finally, a view-dependent deformation technique is described to construct the fashion by deforming the garment template. Our segmentation algorithm is derived from mathematical morphology and image difference method. The deformation technique is related to free-form deformations and vector field of mannequin. With our deformation method, the main feature of fashion is preserved. Compared with other predefined fashion modeling approaches, the efficient and realistic of constructing is greatly increased. The functionality of garment model constructed by our method can apply to some others applications for garment industry.
MUOS U2B Interference Mitigation Analysis (2007)

This paper analyzes the effects on signal-to-noise ratio (SNR) caused by undesired interference within the user-to-base (U2B) MUOS spectrum, and the spectral modifications of the WCDMA waveform designed to combat such interference. Spectral modifications consist of waveform whitening and notching, and are applied to improve performance in the presence of background UHF interference, legacy interferers, and Multiple Access Interference (MAI). Spectral whitening applied at the MUOS receiver mitigates interference by reducing interference power at the demodulator, at a small loss of desired signal power. SNR degradation may be further reduced by applying the spectral whitening calculated at the receiver to the transmitted signal. This technique improves performance by concentrating transmitted power in spectral locations known to be free of interference.
Excitation of molecular rotation by periodic microwave pulses. A testing ground for Anderson localization (1986)

We study the excitation of molecular rotation by microwave pulses of duration σ which occur periodically with frequency ω. We analyze the molecular dynamics both classically and quantum mechanically and consider situations where the coupling of the field to the molecule is strong. In both approaches, the angular momentum transmitted to the molecule is confined to a finite band of width ≊1/σ. But, while the classical dynamics displays chaotic features, the quantum treatment distinguishes clearly between two regimes. Resonance excitation occurs when ω is rationally related to the basic rotation frequency ω0. Off resonance (ω/ω0 irrational), the probability to transfer angular momentum to the molecule is small and the underlying mechanism for this effect is analogous to the Anderson model of localization in a one-dimensional random lattice with a finite number of sites. We show that the conditions required by our analysis can be achieved with, e.g., PbTe or CsI molecules and conventional field strengths and we propose this system as an experimental testing ground for the Anderson localization mechanism.
Isocyanates in marine sponges: Axisocyanate-3, a new sesquiterpene from Acanthella cavernosa (2006)

The isolation of axisocyanate-3 as a minor component of Acanthella cavernosa has been confirmed by spectroscopic characterisation of the metabolite, and by conversion of a mixture of axisothiocyanate-3 and axisocyanate-3 to their diethyl(thio)urea derivatives. The role of isocyanates in the formation of urea metabolites in sponges has been investigated through a model study with a menthyl-derived isocyanate.
A computational approach to reconstructing gene regulatory networks (2004)

With the rapid accumulation of gene expression data in publicly accessible databases, computational study of gene regulation has become an obtainable goal Intrinsic to this task will be data mining tools for inferring knowledge from biological data. In this project, we have developed a new data mining technique in which we adapt the connectivity of a recurrent neural network model by indexing regulatory elements and including nonlinear interaction terms. The new technique reduces the number of parameters by O(n), therefore increasing the chance of recovering the underlying regulatory network. In order to fit the model from data, we have developed a genetic fitting algorithm with O(n) time complexity and that adapts the connectivity during the fitting process until a satisfactory fit is obtained. We have implemented this fitting algorithm and applied it to two data sets: rat central nervous system development (CNS) data with 112 genes, and yeast whole genome data with 2467 genes. With multiple runs of the fitting algorithm, we were able to efficiently generate a statistical pattern of the model parameters from the data. Because of its adaptive features, this method will be especially useful for reconstructing coarse-grained gene regulatory network from large scale or genome scale gene expression data sets.
Development of a Variable Roller Pump and Evaluation of its Power Saving Potential as a Charge Pump in Hydrostatic Drivetrains (2015)

Predložená doktorandská dizertačná práca (ďalej len práca) sa zaoberá rozsiahlou analýzou valčekového hydrogenerátora s premenlivým geometrickým objemom a predikciou výkonových úspor dosiahnutých aplikáciou navrhnutého valčekového hydrogenerátora s premenlivým geometrickým objemom v hydrostatickom pohone vybraných mobilných pracovných strojov. Teoretický rozbor princípov fungovania valčekového hydrogenerátora a teória jednorozmerného simulačného modelu sú popísané v prvej časti práce. Na základe odvodenej teórie je vytvorený simulačný model, ktorý je vhodný na predikciu priebehu tlaku v komorách valčekového hydrogenerátora, síl pôsobiacich na valček a na predikciu vnútorných únikov vzniknutých skratovaním rozvodovej dosky, ktoré majú priamy vplyv na objemovú účinnosť valčekového hydrogenerátora. Simulačný model bol úspešne použitý pre optimalizáciu rozvodových dosiek valčekového hydrogenerátora a vhodnosť simulačného modelu potvrdili následné merania Práca obsahuje aj analýzu síl pôsobiacich na vodiaci prstenec, ktorej výsledky boli taktiež potvrdené meraním. Analýza týchto síl môže vylepšiť v konečnom dôsledku parametre budúcich tlakových regulácii. Práca ďalej obsahuje základné porovnanie použitých tlakových regulácii. Všetky uskutočnené merania potvrdili, že valčekový hydrogenerátor s premenlivým geometrickým objemom s testovanými tlakovými reguláciami je schopný úspešne pracovať v hydrostatickej prevodovke. Druhá časť práce analyzuje potenciál výkonových úspor valčekového hydrogenerátora s premenlivým geometrickým objemom pre dve mobilné aplikácie - teleskopický nakladač s hmotnosťou 9 ton a kombajn s hmotnosťou 20 ton. Analýza vyžaduje jednorozmerný simulačný model hydrostatického pohonu s teplotnou predikciou hydrostatickej prevodovky. Dva rozdielne koncepty variabilného doplňovacieho systému hydrostatickej prevodovky sú porovnané so štandardným doplňovacím systémom pre pracovný a transportný režim oboch vybraných typov vozidiel. Simulácia pohonu vozidla s valčekovým hydrogenerátorom s premenlivým geometrickým objemom vo funkcii doplňovacieho hydrogenerátora a obtokovou clonou potvrdili vyššie úspory iba v prípadoch, kedy rýchlosť doplňovacieho hydrogenerátora bola výrazne vyššia a prietok cez obtokovú clonu do skrine hlavného hydrogenerátora zabezpečil dostatočné chladenie. Najvyššie výkonové úspory boli dosiahnuté s premenlivým preplachovacím systémom, ktorého prietok sa menil podľa požiadaviek hydrostatickej prevodovky. Záver druhej časti práce sa zaoberá metodikou dimenzovania veľkosti doplňovacieho hydrogenerátora.
Si Complies with GaN to Overcome Thermal Mismatches for the Heteroepitaxy of Thick GaN on Si (2017)

Heteroepitaxial growth of lattice mismatched materials has advanced through the epitaxy of thin coherently strained layers, the strain sharing in virtual and nanoscale substrates, and the growth of thick films with intermediate strain-relaxed buffer layers. However, the thermal mismatch is not completely resolved in highly mismatched systems such as in GaN-on-Si. Here, geometrical effects and surface faceting to dilate thermal stresses at the surface of selectively grown epitaxial GaN layers on Si are exploited. The growth of thick (19 µm), crack-free, and pure GaN layers on Si with the lowest threading dislocation density of 1.1 × 10<sup>7</sup> cm<sup>-2</sup> achieved to date in GaN-on-Si is demonstrated. With these advances, the first vertical GaN metal-insulator-semiconductor field-effect transistors on Si substrates with low leakage currents and high on/off ratios paving the way for a cost-effective high power device paradigm on an Si CMOS platform are demonstrated.

An Approach to Establish Trusted Application (2010)

Trusted Computing offer great opportunities to enhance security and privacy of the user. Trusted Platform Module (TPM) is the implementation of the trusted platform initiatives on a chip under Trusted Computing Group (TCG). The TPM chip that is similar to smart card but hardwired onto motherboard, hence making it tamper resistant from remote attack. To interface with the TPM chip, the TCG prescribe a standard interface to communicate with the TPM. However, there are some difficulties in interfacing an application to the TPM. Acquiring full knowledge of Trusted Computing is a critical success factor to successfully modify existing application including design, coding and testing the TPM based application. This paper presents a method that allows existing application running on a platform without a TPM to utilize the TPM functionalities.

Red blood cell adhesion: I. determination of the ionic conditions for adhesion to an oil-water interface (1980)

We have examined the adhesion of glutaraldehyde-treated human red blood cells to a clean liquid hydrocarbon interface as a function of sodium chloride concentration. Cells adhere reversibly to the interface over a wide range of concentrations but fail to do so below about 0.1 mM. Adherent cells do not alter the tension of the oil/water interface. These results show that cells can adhere by physical forces in special situations without biochemical interactions. The data provide a basis for calculating the size of the physical forces.
In vitro coupled transcription-translation of linear DNA fragments in a lysate derived from a recB rna pnp strain of Escherichia coli (1983)

A recB21 derivative (CLB7) of an Escherichia coli rna-19 pnp-7 strain (PR7) was constructed for use in examining the in vitro coupled transcription-translation of linear DNA. The expression of linearized DNAs in CLB7 (recB21 rna-19 pnp-7) lysates was enhanced significantly when compared with expression of the same DNAs in lysates prepared from the PR7 or the original recB21 (CF300) strains. In addition, the endogenous incorporation of [35S]methionine into protein was considerably reduced in CLB7 lysates relative to lysates derived from the original recB21 strain.
Machine Learning Based Prior-Knowledge-Free Calibration for Split Pipelined-SAR ADCs with Open-Loop Amplifiers Achieving 93.7-dB SFDR (2019)

The paper presents a machine-learning based calibration scheme for split pipelined-SAR ADCs with open-loop residual amplifiers. Different from conventional methods, the proposed scheme is prior-knowledge-free. The scheme adopts a two-layer neural network, and directly uses the bit-wise comparator results as inputs. The neural network compensates the distortion and can be compressed by 75% due to the network’s sparsity. A 14-bit 60-MSps split pipelined-SAR ADC with gain boosted dynamic amplifiers is fabricated in 28nm CMOS to validate the scheme. The measurement results show the ADC achieves an SFDR of 93.7 dB and an ENOB of 10.7b, consuming 2.79 mW. To the authors’ knowledge, it achieves the best SFDR among Nyquist ADCs with open-loop amplifiers.

A quantitative analysis of low density polyethylene and linear low density polyethylene blends by differential scanning calorimetery and fourier transform infrared spectroscopy methods (1998)

Abstract Blends of low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) are widely used for blown film applications. An accurate and rapid test scheme to identify the type and composition of α‐olefin in LDPE/LLDPE blends has been developed that utilizes differential scanning calorimetery (DSC) and Fourier transform infrared (FTIR) spectroscopy techniques. The melting point of LDPE varies with density and usually is in the range of 106°C to 112°C for film grade resins. The DSC thermogram of LLDPE is characterized by a broad range of melting peaks with a lower melting peak around 106°C to 110°C and a higher one in the range of 120°C to 124°C. In a blend with LDPE, the ratio of the two endothermic peak heights changes. At a given weight percent of LDPE, this ratio depends on the type of LLDPE (i.e., the comonomer used). Separate calibrations for butene‐1, hexene‐1, and octene‐1 LLDPEs have been developed to quantify the blend composition from DSC thermograms where the α‐olefin type is successfully identified by FTIR over the entire blend composition range. The calibration curves are applicable to narrow melt index (MI) and density range conventional film grade LDPE and LLDPE resins and are not intended to be used for the metallocene type LLDPEs.
Introduction (1997)

Historically, education has been both parent and child to the developing nation state. The national education system as a universal and public institution first emerged in post-revolutionary Europe as an instrument of state formation. It provided a powerful vehicle for the construction and integration of the new nation state and became one of its chief institutional supports. Since then few nations have embarked on independent statehood without recourse to its ideological potential; even the older states, at least in periods of war and crisis, have continued to view education as a valuable source of national cohesion and a key tool for economic development. However, the role of the nation state is now changing, and with it the place of education.
Vertical Cavity Surface Emitting Lasers for communications (2000)

Vertical Cavity Surface Emitting Lasers (VCSELs) are a novel type of laser in which the lasing light is emitted from the surface of the device, perpendicular to the gain layer, rather than from the edge of the laser, parallel to the gain layer. These lasers show interesting behavior, particularly involving mode dynamics and polarization. They show promising characteristics for use in communications applications but their behavior needs to be further understood before they can reach their potential. This chapter attempts to review VCSELs generally and discuss their use in communications systems.
Design and Construction of the PT-1 Prototype Plasmoid Thruster (2006)

The design and construction of a plasmoid thruster prototype is described. This thruster operates by expelling pre‐detached plasmoids at high velocities. These plasmoids are field reversed configuration plasmas which are formed by reversing a magnetic flux frozen in an ionized gas inside a theta‐pinch coil. The pinch coil is a unique multi‐turn, multi‐lead design chosen for optimization of inductance and field uniformity. The coil is wound around an alumina ceramic core and the operation of the thruster is completely electrode‐less. The design of this thruster follows a series of experiments at NASA MSFC based on a single turn theta‐pinch coil called the “Plasmoid Thruster Experiment.” Key issues are addressed which affect the efficiency of the PT‐1. Testing of this device will begin in FY06 at the NASA MSFC Propulsion Research Center.
Studies towards a Conjugate Vaccine for Anthrax: Synthesis of the Tetrasaccharide Side Chain of the <i>Bacillus anthracis</i> Exosporium (2006)

Abstract The first synthesis of β ‐ L ‐glycoside 17 of the tetrasaccharide β ‐Ant‐(1 → 3)‐ α ‐ L ‐Rha p‐ (1 → 3)‐ α ‐ L ‐Rha p‐ (1 → 2)‐ L ‐Rha p is described ( Schemes 1–3 ). Its spacer can be functionalized to make it amenable to conjugation to proteins by different conjugation methods. The synthesis was performed in a stepwise manner starting from the aglycon‐bearing terminal saccharide with thioglycosides as glycosyl donors. To attach the upstream terminal anthrose residue, the assembled linker‐equipped trisaccharide was glycosylated with ethyl 4‐azido‐3‐ O ‐benzyl‐2‐ O ‐(bromoacetyl)‐4,6‐dideoxy‐1‐thio‐ β ‐ D ‐glucopyranoside ( 11 ). Further functionalization of the tetrasaccharide thus obtained, followed by deprotection gave the target substance 17 . Synthesis of substructures of 17 equipped with the same spacer, namely β ‐ L ‐Rha p ‐1‐ O ‐(CH 2 ) 5 COOMe ( 21 ), α ‐ L ‐Rha p ‐(1 → 2)‐ β ‐ L ‐Rha p ‐1‐ O ‐(CH 2 ) 5 COOMe ( 22 ), and α ‐ L ‐Rha p ‐(1 → 3)‐ α ‐ L ‐Rha p ‐(1 → 2)‐ β ‐ L ‐Rha p ‐1‐ O ‐(CH 2 ) 5 COOMe ( 23 ), is also described ( Scheme 4 ).
[What have we learned about inhibitors of the renin-angiotensin system?]. (1986)

With orally active angiotensin converting inhibitors it is now possible to block the renin-angiotensin system chronically. These agents given alone normalize blood pressure of many hypertensive patients. In the remaining, an additional salt subtraction, induced for example by diuretics, is necessary to further reduce blood pressure. In patients with congestive heart failure, angiotensin converting enzyme inhibitors increase cardiac output and exercise capacity, both acutely and chronically. Adverse reactions resulting from blockade of the renin-angiotensin system can be predicted to a large extent and therefore are most often easily avoided. Angiotensin converting enzyme inhibitors like captopril and enalapril, because of their efficacy and good acceptability are likely to become important drugs for the treatment of hypertension and congestive heart failure.
The value of screening (1981)

While it seems obvious that diagnosis of cancers by screening early in their asymptomatic stages should result in improved outcomes, for most cancers proof in clinical practice is elusive. Various characteristics of cancers themselves, screening tests, and screening programs, are critical in estimating the potential value of particular screening efforts. Cancer favorable for screening are those with a high prevalence in the patients screening (high-risk patients), a long detectable preclinical phase, and conditions in which early treatment beneficially alters the natural history. A good screening test is one with high sensitivity and specificity, as the test is commonly performed and interpreted, and minimal financial and other costs or risks. Favorable evaluation of a screening program includes demonstrated reduction in morbidity and mortality, preferably in a randomized controlled trial. Interpretation of experimental and nonexperimental results of screening programs in complex. Evaluation of the multidimensional costs of screening depends on the value system of the observer: patient, physician, or public health official. Comparison of costs and benefits with those of other activities is helpful in decision making and in assessing the value of screening.
Technical note: A quick and more sensitive method to identify pork in processed and unprocessed food by PCR amplification of a new specific DNA fragment. (2001)

We developed and evaluated a PCR procedure to detect pork in heated and unheated meat, sausages, canned food, cured products, and pâtés using a faster, more specific, and more sensitive method than others previously described. Isolation of a new DNA-specific porcine repetitive element was performed by nonspecific PCR amplification. After analyzing this repetitive sequence, a pair of primers were synthesized. To confirm the effectiveness and specificity of this fragment, 55 pig blood DNA samples (from differents breeds) were tested and positive results were obtained. With 200 samples tested from other species, the specific pork amplification was not detected. Using this method, we can partially quantify degree of contamination, depending on the PCR amplification cycles, detecting up to 0.005% pork in beef and 1% pork in duck pâté using 30 and 20 PCR amplification cycles, respectively. The amount of porcine DNA detected in cattle DNA was 1.25 and 250 pg when using 30 and 20 amplification cycles, respectively. Pork has been identified in both heated and unheated meat products, sausages, canned food, hamburgers, and pâtés. In conclusion, specific PCR amplification of a repetitive DNA element seems to be a powerful technique for the identification of pork in processed and unprocessed food, because of its simplicity, specificity, and sensitivity (with 30 amplification cycles we can detect 0.005% pork). Furthermore, it is a very fast method, because 1% pork contamination can be detected with 20 PCR cycles. The procedure is also much cheaper than other methods based on RFLP-PCR, immunodiffusion, or other techniques that need expensive equipment.
Magnetogalvanic approach to isolation of analog circuits (1994)

An isolation amplifier circuit is described that utilizes a magnetic field in combination with a magnetosensitive lateral bicollector transistor (magnetotransistor-MTr) to isolate input and output signals. The input signal is applied to a conducting coil via an input amplifier and voltage-to-current converter. The output signal is proportional to the collector current difference (/spl Delta/I/sub c/) of the MTr which is a linear function of the applied magnetic field. Temperature stability was achieved by microthermostating the magnetotransistor. A particular design of the isolation block is proposed, and experimental results are depicted. A dynamic range of more than 54 dB has been achieved at a bandwidth of 10 kHz. The nonlinearity was only 0.05%.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Adaptive and Matched Filtering with a SAW/FET Programmable Transversal Filter (1986)

We describe the operation of a SAW/FET programmable transversal filter as both a matched filter and an adaptive filter. The SAW/FET device incorporates surface-acoustic-wave (SAW) signal propagation in conjunction with a field-effecttransistor(FET)-controlled sampling array. The SAW/FET device has a 1.5-us impulse response, 350 taps, and 100-MHz programmable bandwidth centered at 175 MHz. The on/off ratio of each individual tap is 30 dB. As a matched filter, the SAW/FET device is demonstrated using both 31- and 63-chip m-sequences, showing nearly ideal sldelobe performance. The adaptive processor uses a digital computer to calculate the tap-weight updates according to the least-mean-squares (LMS) algorithm and achieves up to 25 dB of CW cancellation.
