Analysis of Different Control Strategies and Operating Modes of Compact Hybrid Planetary Transmission Drive (2005)

This paper presents the original compact hybrid planetary transmission drive (CHPTD) as a solution of hybrid drive for urban bus. CHPTD uses only one motor. Planetary gear with two degrees of freedom is directly connected with the motor and internal combustion engine (ICE), which explains its compact construction. The third shaft of planetary gear via differential gear propels traction wheels. The clutch-brake system of CHPTD can reduce the planetary gear degrees of freedom, which permits to obtain three operating modes of hybrid drive system: hybrid, pure electric and pure engine. These operating modes provide possibilities for different bus drive, depending on vehicle starting way, downtown or suburban operations. The flexibility of CHPTD application permits properly adjusting power distribution and splitting power between battery and engine, which is the reason of very efficient driving. CHPTD as a kind of "optimized hybrid drive" consumes significantly less energy (fuel and electricity) than well-known series hybrid drive.
Self-Cleaning Tubular-Membrane Module (1983)

Tubular membranes made self-cleaning with aid of flow reversing valve. Sponge balls scrub membrane surfaces as they travel inside membrane tubes. A four-way flow-reversal valve automatically reverses flow in tubes at preset intervals so sponge balls reciprocate along tubes. Baskets at ends of tubes prevent sponges from escaping. Automatic cleaning feature added to existing membrane processing equipment with minimal modifications.
Reversible disruption of cultured endothelial monolayers by sulphated fucans (1983)

We have examined the effects of a variety of polysaccharides and glycoconjugates on the organization and morphology of cultured A14CL-1 endothelial monolayers. The sulphated fucose-containing polysaccharides, fucoidin and sea-urchin egg jelly fucan, induce a dramatic disruption of the organization of the monolayers, characterized by the retraction of adjacent borders of cells exposing areas of the subendothelial matrix. This effect, which occurs at a fucoidin concentration of 10 micrograms/ml, is rapidly reversible after the fucoidin-containing medium is removed. Within 1 h after replacement with fresh medium many cell contacts are re-established; within 20 h the fucoidin-treated monolayers closely resemble the untreated controls. The effect of the sulphated fucose-containing polysaccharides is specific. Of a wide variety of sulphated polysaccharides and glycoconjugates tested, only fucoidin and the egg jelly fucan produce a detectable alteration in the morphology of cultured endothelial monolayers. The endothelial monolayer has specific binding sites for fucoidin. The binding of fucoidin is saturable and a maximum of 4.5 X 10(5) molecules of fucoidin are bound per cell with an apparent affinity of 2.3 X 10(-7) M. A significant proportion (26%) of the total monolayer-associated fucoidin is apparently internalized by the endothelial cells after incubation with fucoidin for 1 h at 37 degrees C. The morphological response to fucoidin is probably not due to its internalization, since the effect is observed at 7 degrees C where little uptake (3.5%) occurs. Fucoidin appears to bind at two distinct sites on endothelial monolayers. One site is inhibitable by heparin, while the other site seems to be specific for fucoidin. The observation that fucoidin still induces the retraction of the endothelial cells in the presence of a 100-fold excess of heparin, suggests that binding at the fucoidin-specific site is responsible for the morphological effect of fucoidin. In addition, fucoidin has no detectable effect on monolayers of 3T3 and BHK fibroblast-like cells at 1 mg/ml, 100-fold higher than the concentration required to produce an effect on endothelial cells. Among the possible interpretations of these results is that sulphated fucose-containing glycoconjugates may play a role in the adhesive interactions of endothelial cells.
Poly(thioester) by Organocatalytic Ring-Opening Polymerization (2015)

Organocatalysts typically used for the ring-opening polymerization (ROP) of cyclic ester monomers are applied to a thiolactone, <i>ε</i>-thiocaprolactone (tCL). In the absence of an H-bond donor, a nucleophilic polymerization mechanism is proposed. Despite the decreased ability of thioesters and thiols (versus esters and alcohols) to H-bond, H-bonding organocatalysts-a thiourea in combination with an H-bond accepting base-are also effective for the ROP of tCL. The increased nucleophilicity of thiols (versus alcohols) is implicated in the increased <i>M</i><sub>w</sub>/<i>M</i><sub>n</sub> of the poly(thiocaprolactone) versus poly(caprolactone), but deleterious transesterification is suppressed in the presence of a thiourea. The thioester monomer, tCL, is shown to be thermodynamically similar to <i>ε</i>-caprolactam but kinetically similar to <i>ε</i>-caprolactone.
Enhanced ultraviolet photoconductivity in semiconducting ZnGa2O4 thin films (2001)

We have investigated the conductivity and photoconductivity response of undoped and Li-doped ZnGa2O4 epitaxial films grown using pulsed-laser deposition. A significant enhancement of the ultraviolet (UV) photoresponse is observed with Li doping that also correlates with an enhanced luminescent intensity. The wavelength dependence observed for creation of free carriers under UV excitation suggests that the transition is either band-to-band or involves a defect level near the band edge. Moderate n-type dark conductivity is observed for undoped films processed under reducing conditions. With Li doping, dark conductivity is reduced, suggesting that lithium ions in the zinc gallate lattice serve as deep acceptors. In addition, Li doping effectively eliminates persistent photoconductivity that is commonly observed in undoped films, suggesting the possible use of Li-doped ZnGa2O4 as a visible wavelength blind UV photodetector.
Quantitative trait loci mapping associated with plant regeneration ability from seed derived calli in rice (Oryza sativa L.). (2001)

Quantitative trait loci (QTLs), which are associated with the ability of plant regeneration from seed derived calli, were detected using a recombinant inbred (RI) population from a cross between 'Milyang 23 (toingil)' and 'Gihobyeo (japonica)' in rice (Oryza sativa L.). A tongil type cultivar, 'Milyang 23', has a lower frequency of callus induction and plant regeneration than those of japonica 'Gihobyeo'. Transgressive segregations were observed for the callus induction rate and plant regeneration ability from seed derived calli of the RI population. An interval mapping analysis was used to identify the QTL controlling the plant regeneration ability. Two QTLs for the callus induction rate were detected on chromosomes 1 and 2, explaining the 10.9% total phenotypic variation. Four QTLs that are associated with the plant regeneration ability were located on chromosomes 2, 3, and 11, accounting for 25.7% of the total phenotypic variation.
Processing of thermal insulation materials with controlled porosity (1995)

Slip-cast cordierite-based materials with reduced thermal conductivity have been manufactured with controlled introduction of porosity. The porosity was obtained by addition of different kinds of fillers (hollow Al-silicate spheres, paraffin, polystyrene, carbon black or starch particles). The processing and the ultimate thermal and mechanical properties were evaluated. The results showed that additions of corn or potato starch gave the most favourable concept, considering the processing and porosity control. A homogeneous distribution of spherical pores with the sizes 5-25 or 15-40 {mu}m was obtained after sintering. Slip-cast cordierite with 37% porosity had a thermal conductivity of 1.7 W/mK (compared with 3.7 W/mK for fully dense cordierite), and a bending strength above 50 MPa. The porosity effect correlated very well to theoretical models by Maxwell and, hence, the thermal conductivity of the porous ceramic material could be predicted.
Discrete chaos - based Random Number Generator (2014)

This paper presents a low power True Random Number Generator (TRNG), based on the discrete time-chaos, intended for a RFID security applications, to be developped on CMOS 350nm standard technology. The circuit relies on a discrete time chaotic oscillator to generate patterns to be sampled to get a raw random signal to be debiased by a digital corrector.
Robust discrete-timeH∞-optimal tracking with preview (1998)

The problem of robust, finite-time, H∞-tracking for linear, discrete, time-varying systems is considered from the game theory point of view. No a priori knowledge of the dynamic model of the reference signal to be tracked is assumed, and the parameters of the system are not completely known. Two tracking problems are investigated, depending on whether the reference signal is perfectly known in advance, or previewed in a fixed-interval of time ahead. An augmented state-space description that converts the parameter uncertainty to bounded energy signal is used. A tracking game is then defined and solved. It is shown that its saddle-point equilibrium, if it exists, guarantees a prescribed H∞-norm performance of the tracker, for all possible parameters. © 1998 John Wiley & Sons, Ltd.
Decision Making for ERP Investments from the Perspective of Organizational Impact -Preliminary Results from an Empirical Study (1999)

This study addresses the complex relationship between decision making for ERP investments and the consideration of organizational impact under 2 different perspectives: Enterprise Resource Planning (ERP) system decisions in organizations with Business Process Improvement (BPI) in particular Business Process Reengineering (BPR) efforts and ERP decisions without BPI/BPR efforts. On the basis of a questionnaire sent to 813 austrian middle und large scale organizations, this paper shows that companies have weighted the inquired decision aspects very differently. ERP decisions are frequently made without a complete consideration and evaluation of all inquired aspects. Furthermore mainly standard financial measures have been used to support the decision. We propose that ERP decision making models can be based on the concept bounded rationality and satisficing.
Spatial Distribution of Phosphorus in Water of East and West Lake in Quanzhou, Fujian (2008)

Several types of phosphorus in water from different areas of East and West Lake in Quanzhou were investigated,then their spatial distribution character was discussed.The results suggest that the mean mass fractions of total phosphorus in East Lake and West Lake are 0.470 mg·L-1 and 0.203 mg·L-1,respectively.The dissoluble phosphate in East Lake water accounts for 60.2%～87.6% in total phosphorus,while this figure in West Lake is 38.1%～73.2%.This indicates that the soluble reactive phosphorus which is the main form in East Lake water accounts for 60%～92% in total dissoluble phosphorus.The soluble reactive phosphorus in West Lake water accounts for 34.7%～68.5% in total dissoluble phosphorus.The total dissoluble phosphate and the soluble reactive phosphorus are distribute homologous in each lake water.
Efficient scheme for motion estimation and block size mode selection in H.264 (2005)

The paper presents efficient algorithms for enhancing the computational performance of an H.264 video encoder. We employ previously calculated motion vectors and variable block size modes from neighboring blocks to select the best modes and motion vectors for the current macroblock. The scheme results in 40% to 70% improvement in the encoding time over a reference implementation without degradation in the subjective quality. The average SNR and the compression performance do not show variation from the reference codec implementation. Results based on a number of video sequences are presented that clearly demonstrate the benefit of the proposed motion estimation and block size mode selection algorithm. The proposed scheme has been shown to provide the least computational load with improvement in the encoding time. The reduction in memory requirements and calculations makes this scheme useful for VLSI implementation and realtime applications.
Empirical characterization of modular variable stiffness inflatable structures for supernumerary grasp-assist devices (2017)

This paper presents the design, fabrication, and experimental characterization of modular, variable stiffness inflatable components for pneumatically actuated supernumerary robotic (SR) grasp-assist devices. The proposed SR grasp-assist devices are comprised of soft rigidizable finger phalanges and variable stiffness pneumatic bending actuators that are manufactured using soft lithography fabrication methods. The mechanical and kinematic properties of these modular, inflatable components are characterized experimentally under various loading conditions and over a range of geometric design parameters. The resulting data-driven properties are then used to predict the grasp strengths and motion patterns of SR grasp-assist device configurations designed to accommodate the manipulation of daily living objects. Experimental results demonstrate the ability to program grasp synergies into SR fingers by strategic inflation of the bending actuator antagonist chambers (varying mechanical stiffness), without the need for complicated, high-power mechanisms or precise, low-level motion control. The results also demonstrate the underactuated grasp adaptations enabled by modular inflatable components and the ability to predict mechanical grasping capabilities of wearable pneumatic SR grasp-assist devices using insights from empirical data.
Direct regulation of <i>nacre</i>, a zebrafish <i>MITF</i> homolog required for pigment cell formation, by the Wnt pathway (2000)

We have shown that Wnt signals are necessary and sufficient for neural crest cells to adopt pigment cell fates. nacre, a zebrafish homolog of MITF, is required for pigment cell differentiation. We isolated a promoter region of nacre that contains Tcf/Lef binding sites, which can mediate Wnt responsiveness. This promoter binds to zebrafish Lef1 protein in vitro, and a nacre reporter construct is strongly repressed by dominant-negative Tcf in melanoma cells. Mutation of Tcf/Lef sites abolishes Lef1 binding and reporter function in vivo. Wnt signaling therefore directly activates nacre, which in turn leads to pigment cell differentiation.
Experimental behaviour of diaphragms in post-tensioned timber frame buildings (2014)

Floor diaphragms have an important role in the seismic behaviour of structures, as inertia forces are generated by their masses and then transferred to the lateral load resisting system. Diaphragms also link all other structural elements together and provide general stability to the structure. As with most other structural components, there is concern about damage to floor diaphragms because of displacement incompatibilities. This paper describes two different experiments on engineered timber floors connected to post-tensioned timber frames subjected to horizontal loading. \nFirst a full scale two-bay post-tensioned frame was loaded with lateral loads through a stressed-skin floor diaphragm. Different connection configurations between the floor units on either side of the central column were tested. Secondly a three dimensional, three storey post-tensioned frame building was tested on a shaking table. The diaphragm consisted of solid timber panels connected to the beams with inclined fully threaded screws. For all tested connections, the diaphragm behaviour was fully maintained throughout the testing and no damage was observed.\nThe test results showed that careful detailing of the floor panel connections near the beam-column-joint and the flexibility of timber elements can avoid floor damage and still guarantee diaphragm action at high level of drifts in post-tensioned timber frame buildings.

Explosive Percolation Is Continuous (2011)

"Explosive percolation" is said to occur in an evolving network when a macroscopic connected component emerges in a number of steps that is much smaller than the system size. Recent predictions based on simulations suggested that certain Achlioptas processes (much-studied local modifications of the classical mean-field growth model of Erdős and Rényi) exhibit this phenomenon, undergoing a phase transition that is discontinuous in the scaling limit. We show that, in fact, all Achlioptas processes have continuous phase transitions, although related models in which the number of nodes sampled may grow with the network size can indeed exhibit explosive percolation.
An investigation of the minimal structural conditions lor the dirnroth‐type rearrangement in the polyazaindolizine series (1971)

Abstract In the imidazo[1,2]diazine series, only the imidazo[1,2‐ a ]‐ and [1,2‐ c ] pyrimidine systems were found to undergo a Dimroth‐type rearrangement under basic aqueous conditions. The electronic and steric factors influencing the rearrangement rates of methyl substituted imidazo‐[1,2‐ a ] pyrimidines are discussed.

DAMAGE DETECTION IN A TRIPOD TOWER PLATFORM (TTP) USING MODAL ANALYSIS (1992)

When structural damage occurs, the dynamic characteristics of the structure change correspondingly. Consequently, Frequency Response Functions (FRFs) of the structure could be used to detect the damages in a Tripod Tower Platform (TTP) structure. A 1/50th scale elastic model made of acrylic plastic is used to represent the real TTP structure. Strain gauges are used, along with accelerometers and displacement transducers, for modal testing. Since strains and stresses are the prime response parameters of interest in structural behaviour, and strain gauges are widely used to monitor them, FRFs using strains, displacements and accelerations, are obtained at different damage levels of the structure. Effects of damage on FRFs are investigated considering frequency shifts, damping, and amplitude changes. Strain FRFs are also compared with the acceleration and displacement FRFs, and the differences discussed. The experimental values are compared with the numerical computations carried out using the finite element modules available in the computer program SDRC-IDEAS. The sensitivities of the various sensors to detect changes are also determined and compared.
Regulation of Na+-coupled Glucose Transport in LLC-PK1 Cells (1995)

In an exploration of the molecular basis of cyclic AMP-induced stabilization of Na+/glucose cotransporter mRNA (SGLT1 isoform) accompanying cell differentiation in the pig kidney cell line LLC-PK1, we have identified a 48-kDa cytoplasmic protein factor, designated SG-URBP, which specifically binds a 120-nucleotide sequence within the 3'-untranslated region of the SGLT1 message. A 46-nucleotide uridine-rich element within this region appears necessary for specific binding, and the presence of the 3'-untranslated region is necessary for message stabilization by cyclic AMP. The binding activity of SG-URBP is up-regulated after cyclic AMP elevation and protein kinase A activation, whereas protein dephosphorylation either in vivo or in vitro is associated with loss of binding activity. The increase in SG-URBP binding activity correlates with an increase in the half-life of the SGLT1 message, suggesting a cause and effect relationship.
