Robust unscented Kalman filtering for nonlinear uncertain systems
Authors: Xiong K. , Wei C. L. , Liu L. D. 
Published: April 2010

AbstractA derivative‐free robust Kalman filter algorithm is proposed for nonlinear uncertain systems. The unscented transform (UT) is adopted instead of the linearization technique to obtain the solution of theH∞filter Riccati equation. A robust unscented Kalman filter (RUKF) is derived to guarantee an optimized upper bound on the estimation error covariance despite the model uncertainties and the approximation error of the UT. The proposed algorithm is applied to a satellite attitude determination system. Simulation results show that the RUKF is more effective than the unscented Kalman filter (UKF) in cases where alignment errors are present.

A pedagogical Web service‐based interactive learning environment for a digital filter design course: An evolutionary approach
Authors: Wu Wen‐Hsiung , Chen Wei‐Fan , Wang Tsung‐Li , Su Te‐Jen 
Published: April 2010

AbstractThe course of digital filter design in electronic/electrical engineering involves complicated mathematical equations and dynamic waveform variations. It is a consensus among educators that using simulation tools assist in improving students' learning experiences. Previous studies on system simulation seemed to lack an appropriate approach to design such a course. Few emphasized the design of an interactive learning environment by using an evolutionary approach. This study integrated the design concept of an evolutionary approach and Web service‐based technology into a simulation system entitled Pedagogical Web Service‐Based Interactive Learning Environment (PEWSILE) was introduced. The PEWSILE system contained two interactive learning environments—a simple system and an advanced system. It offered a total of six pedagogical Web services. The simple interactive learning environment included text/color‐based services, and text/color/diagram‐based services. The advanced interactive learning environment included batch‐based, interval change‐based, comparison‐based, and scroll bar‐based services. The study also assessed the students' performance in six pedagogical Web services covering interaction and overall use, usefulness, and intention to use through a questionnaire survey and subsequent interviews. Three significant findings were reported. For example, in the advanced interactive learning environment, the designs of interval change‐based and comparison‐based services make it easier to observe differences in the outcome of parameter change, while batch‐based services lacks the element of waveform comparison. In sum, the findings in this study provide helpful implications in designing engineering educational software. © 2010 Wiley Periodicals, Inc.

Visual interactive environment for study the power electronics using PSCAD‐EMTDC simulation program
Authors: Pănoiu Caius , Pănoiu Manuela , Muscalagiu Ionel , Iordan Anca 
Published: April 2010

AbstractInformational society needs major changes in the educational programs, being necessary to prepare teachers from all fields, in such way to use the information technologies in computer assisted learning. The computer, as auxiliary element of the teacher, is used since few decades, but the new technologies appeared in computer science lead to the necessity to adapt the learning/teaching methodologies in such way to be based increasingly on information technology. This paper presents a software package, which can be used as educational software, for study the power electronics. This study deals with the simulation of power electronic circuits by using PSCAD EMTDC software. Since the equations and functions can be represented in blocks, simulation method is simple and versatile. The PSCAD models of single and three‐phase rectifiers, PWM choppers and inverters, AC choppers, are developed and performance waveforms are obtained. This study would be useful for obtaining a quick solution for, power electronic networks and for more complex systems containing power electronic circuits. © 2010 Wiley Periodicals, Inc.

AbstractMany severe human pathologies are related to alterations of the fine balance between histone acetylation and deacetylation; because not all such diseases involve hypoacetylation, but also hyperacetylation, compounds able to enhance or repress the activities of histone acetyltransferases (HATs) could be promising therapeutic agents. We evaluated in vitro and in cell the ability of eleven natural polyisoprenylated benzophenone derivatives to modulate the HAT activity of p300/CBP, an enzyme that plays a pivotal role in a variety of cellular processes. Some of the tested compounds bound efficiently to the p300/CBP protein: in particular, guttiferone A, guttiferone E and clusianone inhibit its HAT activity, whereas nemorosone showed a surprising ability to activate the enzyme. The ability of nemorosone to penetrate cell membranes and modulate histone acetylation into the cell together with its high affinity for the p300/CBP enzyme made this compound a suitable lead for the design of optimized anticancer drugs. Besides, the studies performed at a cellular and molecular level on both the inhibitors and the activator provided new insights into the modulation mechanism of p300/CBP by small molecules.
Modulation of Stacking Interactions by Transition‐Metal Coordination: Ab Initio Benchmark Studies
Authors: Mutter Shaun T. , Platts James A. 
Published: April 2010

AbstractA series of ab initio calculations are used to determine the CH⋅⋅⋅π and π⋅⋅⋅π‐stacking interactions of aromatic rings coordinated to transition‐metal centres. Two model complexes have been employed, namely, ferrocene and chromium benzene tricarbonyl. Benchmark data obtained from extrapolation of MP2 energies to the basis set limit, coupled with CCSD(T) correction, indicate that coordinated aromatic rings are slightly weaker hydrogen‐bond acceptors but are significantly stronger hydrogen‐bond donors than uncomplexed rings. It is found that π⋅⋅⋅π stacking to a second benzene is stronger than in the free benzene dimer, especially in the chromium case. This is assigned, by use of energy partitioning in the local correlation method, to dispersion interactions between metal d and benzene π orbitals. The benchmark data is also used to test the performance of more efficient theoretical methods, indicating that spin‐component scaling of MP2 energies performs well in all cases, whereas various density functionals describe some complexes well, but others with errors of more than 1 kcal mol−1.
Gas‐Phase Energetics of Reductive Elimination from a Palladium(II) N‐Heterocyclic Carbene Complex
Authors: Couzijn Erik P. A. , Zocher Eva , Bach Andreas , Chen Peter 
Published: April 2010

AbstractEnergy‐resolved collision‐induced dissociation experiments using tandem mass spectrometry are reported for an phenylpalladium N‐heterocyclic carbene (NHC) complex. Reductive elimination of an NHC ligand as a phenylimidazolium ion involves a barrier of 30.9(14) kcal mol−1, whereas competitive ligand dissociation requires 47.1(17) kcal mol−1. The resulting three‐coordinate palladium complex readily undergoes reductive CC coupling to give the phenylimidazolium π complex, for which the binding energy was determined to be 38.9(10) kcal mol−1. Density functional calculations at the M06‐L//BP86/TZP level of theory are in very good agreement with experiment. In combination with RRKM modeling, these results suggest that the rate‐determining step for the direct reductive elimination process switches from the CC coupling step to the fragmentation of the resulting σ complex at low activation energy.
Sonication‐Assisted Fabrication and Post‐Synthetic Modifications of Graphene‐Like Materials
Authors: Cravotto Giancarlo , Cintas Pedro 
Published: April 2010

AbstractChemistry of and with graphene constitutes a rapidly evolving field that holds much promise for the generation of advanced materials with salient, and often unique, properties and potential applications in different fields. However, reliable, mild, and scalable methods to produce this layered carbonaceous material represent an important bottleneck and are critical for progress in this research area to continue. In this context, the use of ultrasound has become a routine and indispensable step in numerous synthetic protocols, even though most researchers usually overlook the science behind it. This minireview provides some fundamentals on the interaction of sound waves with matter and equally illustrates how sonication assists further synthetic decorations under benign conditions.
On the Structural Chemistry of γ‐Brasses: Two Different Interpenetrating Networks in Ternary F‐Cell Pd–Zn–Al Phases
Authors: Thimmaiah Srinivasa , Miller Gordon J. 
Published: April 2010

AbstractNovel ternary phases, (Pd1−xZnx)18(Zn1−yAly)86−δ (0≤x≤0.162, 0.056≤y≤0.088, 0≤δ≤4), which adopt a superstructure of the γ‐brass type (called γ′‐brass), have been synthesized from the elements at 1120 K. Single‐crystal X‐ray structural analysis reveals a phase width (F$\bar 4$3m, a=18.0700(3)–18.1600(2) Å, Pearson symbols cF400–cF416), which is associated with structural disorder based on both vacancies as well as mixed site occupancies. These structures are constructed of four independent 26‐atom γ‐clusters per primitive unit cells and centered at the four special positions A (0, 0, 0), B (1/4, 1/4, 1/4), C (1/2, 1/2, 1/2) and D (3/4, 3/4, 3/4). Two of these, centered at B and C, are completely ordered Pd4Zn22 clusters, whereas the other two, centered at A and D, contain all structural disorder in the system. According to our single‐crystal X‐ray results, Al substitutions are restricted to the A‐ and D‐centered clusters. Moreover, the outer tetrahedron (OT) site of the 26‐atom cluster at D is completely vacant at the Al‐rich boundary of these phases. Electronic structure calculations, using the tight‐binding linear muffin‐tin orbital atomic‐spheres approximation (TB‐LMTO‐ASA) method, on models of these new, ternary γ′‐brass phases indicate that the observed chemical compositions and atomic distributions lead to the presence of a pseudogap at the Fermi level in the electronic density of states curves, which is consistent with the Hume‐Rothery interpretation of γ‐brasses, in general.
Surface‐Modified Upconverting Microparticles and Nanoparticles for Use in Click Chemistries

Published: April 2010

AbstractA method is described for modifying the surface of upconverting microparticles (UCμPs) and nanoparticles (UCNPs) such that they become amenable to click chemistry. Respective reagents are presented and used in both kinds of particles, either directly or in combination with tetraethoxysilane. The particles also were labeled by using the click reaction, a) with fluorophores to yield materials that have emission colors that depend on the wavelength of excitation; b) with maleinimido groups (so to obtain labels for thiols), and c) with biotin (to make them useful for affinity studies based on the biotin–streptavidin system). We believe that both the UCμPs and UCNPs have the potential of being used in numerous areas including upconversion imaging, biolabeling, and derivatization, but also in encoding and security.
