Empathic Robotic Tutors for Personalised Learning: A Multidisciplinary Approach (2015)

Within any learning process, the formation of a socio-emotional relationship between learner and teacher is paramount to facilitating a good learning experience. The ability to form this relationship may come naturally to an attentive teacher; but how do we endow an unemotional robot with this ability? In this paper, we extend upon insights from the literature to include tools from user-centered design (UCD) and analyses of human-human interaction (HHI) as the basis of a multidisciplinary approach in the development of an empathic robotic tutor. We discuss the lessons learned in respect to design principles with the aim of personalised learning with empathic robotic tutors.
Thermoelectric Mini-Contact Cooler For Hot-Spot Removal In High Power Devices (2006)

Cooling hot-spots with high heat flux (e.g., >1000W/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2 </sup> ) is becoming one of the most important technical challenge facing today's IC industry. More aggressive thermal solutions, than would be required for uniform heating, are highly desired. Solid state thermoelectric coolers (TECs) have received recent attention for hot-spot thermal management. However, present day TECs typically have cooling flux much lower than heat flux in the hot-spots. In this work, we reported an innovative technique - TE mini-contact - to significantly increase cooling flux of TECs for the application in hot-spot cooling. A chip package featuring a TE mini-contact cooler integrated with conventional integrated heat spreader (IHS) and heat sink is designed. The cooling performance of such chip package has been investigated by using a 3-D numeric model. It is found that the cooling in the hot-spot (1250W/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , 400 mum by 400 mum) can be about 19degC better in the proposed package than that achieved in the conventional chip package without TEC. The effects of trench, die thickness, and TEC misalignment on the cooling of the hot-spot are also discussed
Analysis of a long-range interaction between conserved domains of human telomerase RNA (2003)

Telomerase is a ribonucleoprotein complex responsible for maintaining telomere length of eukaryotic chromosomes. Human telomerase has two main components, the human telomerase reverse transcriptase and the human telomerase RNA (hTR). Two domains of hTR essential for telomerase activity are the template domain, comprised of an 11-nt templating and alignment sequence, and the CR4/CR5 domain. Highly conserved residues in the CR4/CR5 domain form the stem-loop P6.1, which is important for assembly and activity of mammalian telomerase. Here, we have determined that stem-loop P6.1 can participate in a long-range RNA-RNA interaction with the template region of hTR. We characterized this interaction through mobility shift assays, mutation analysis, and UV cross-linking experiments. Mutation analysis revealed that the P6.1 loop nucleotides participate in the interaction with the template. The site of interaction at the template domain was determined via UV cross-linking experiments. These data show that an RNA-RNA interaction exists between two highly conserved regions of hTR that are critical for the higher order folding of telomerase RNA. This interaction argues for the proximity of the template and the CR4/CR5 domain, and provides the basis for a revised model of hTR, partitioning the RNA into a catalytic domain and a localization domain.
Humanized CD52 monoclonal antibody campath‐1H as first‐line treatment in chronic lymphocytic leukaemia (1996)

The humanized CD52 monoclonal antibody Campath-1H was used as first-line therapy in nine patients with progressive chronic lymphocytic leukaemia (CLL). Intravenous (n = 5) or subcutaneous (n = 4) injections (up to 30 mg/inj.) were given three times a week for a maximum of 18 weeks. Three patients achieved a complete remission (CR) and five patients a partial remission (PR) (response rate 89%). CLL cells were cleared from blood in all patients and from the bone marrow in seven patients. The response duration time was 8 + -24+ months. Adverse events were mild except for one patient who developed CMV pneumonitis. All patients developed lymphocytopenia (B and T cells) but other haematological toxicities were negligible. Campath-1H is a highly effective and well-tolerated agent in patients with previously untreated CLL and further studies are warranted.
Effect of Solvents on the Preparation of Silica-Coated Magnetic Particles (2001)

Abstract The influence of solvents on magnetic particles aggregation during silica coating by the Stober method has been studied, and a simple method has been developed to produce well-dispersed silica-coated magnetic particles using methanol.
The effect of liming conditions in juice clarification. (2002)

The juice clarification process used in the Australian cane sugar industry is best described as simple defecation. However, there are many variants of this simple process used throughout the cane sugar industry. Milk of lime is often used instead of lime saccharate solutions, lime addition may be batch-wise rather than continuous, and the point of lime addition may be to cold juice (35–40 o C), to intermediate juice (72–76 o C) or to hot juice (100 o C). Despite a wealth of practical experience, the impact that the various liming conditions have on the physical chemistry of clarification is not well known. This study reports some recent laboratory work to quantify the effects of liming techniques on clarified juice quality and floc settling behaviour. The results indicate that liming with lime saccharate gives lower turbidity but higher mud levels and slower settling flocs than liming with milk of lime. However, the clarified juice obtained with saccharate has a higher calcium level but a lower phosphate level than milk of lime clarified juice. The higher calcium level in the clarified juice obtained with saccharate may result in an increase in scale formation in the evaporators. The underlying physical chemistry of the clarification process is used to explain the observed differences in the performance of the various liming techniques.
Synthesis of a Novel Poly(MePEG cyanoacrylate-<i>co</i>-alkyl cyanoacrylate) Amphiphilic Copolymer for Nanoparticle Technology (1997)

In order to develop “stealth” injectable PEG-coated poly(alkyl cyanoacrylate) (PACA) nanoparticles, a novel poly(MePEG cyanoacrylate-co-alkyl cyanoacrylate) copolymer has been synthetized in a simple way by condensing MePEG cyanoacetate esters with formaldehyde in the presence of dimethylamine. This approach allowed the covalent linkage of PEG moieties to the cyanoacrylate polymer, thus avoiding the risk of desorption of PEG, as in the case of a PEG coating obtained by simple adsorption onto preformed nanoparticles. In addition, the condensation procedure allowed a better control of the polymerization process than in the case of anionic polymerization of alkyl cyanoacrylates. Finally, we have shown that the hydrophobicity of the copolymer can be perfectly modulated by adjusting the MePEG cyanoacetate/alkyl cyanoacetate ratio. Characterization of the copolymer has been performed by NMR, GPC, and FTIR analysis. Monodispersed nanoparticles were easily prepared by nanoprecipitation of this amphiphilic copolymer.
Edge extraction by merging 3D point cloud and 2D image data (2013)

Edges provide important visual information by corresponding to discontinuities in the physical, photometrical and geometrical properties of scene objects, such as significant variations in the reflectance, illumination, orientation and depth of scene surfaces. The significance has drawn many people to work on the detection and extraction of edge features. The characteristics of 3D point clouds and 2D digital images are thought to be complementary, so the combined interpretation of objects with point clouds and image data is a promising approach to describe an object in computer vision area. However, the prerequisite for different levels of integrated data interpretation is the geometric referencing between the 3D point cloud and 2D image data, and a precondition for geometric referencing lies in the extraction of the corresponding features. Addressing the wide-ranged applications of edge detection in object recognition, image segmentation and pose identification, this paper presents a novel approach to extract 3D edges. The main idea is combining the edge data from a point cloud of an object and its corresponding digital images. Our approach is aimed to make use of the advantages of both edge processing and analysis of point clouds and image processing to represent the edge characteristics in 3D with increased accuracy. On the 2D image processing part, an edge extraction is applied on the image by using the Canny edge detection algorithm after the raw image data pre-processing. An easily-operating pixel data mapping mechanism is proposed in our work for corresponding 2D image pixels with 3D point cloud pixels. By referring to the correspondence map, 2D edge data are merged into 3D point cloud. On the point cloud part, the border extracting operator is performed on the range image. As a preparation work, the raw point cloud data are used to generate a range image. Edge points in the range image, points with range, are converted to 3D point type with the application of the Point Cloud Library (PCL) to define the edges in the 3D point cloud.
Structural insights into eukaryotic DNA replication (2014)

THREE DNA POLYMERASES OF THE B FAMILY FUNCTION AT THE REPLICATION FORK IN EUKARYOTIC CELLS: DNA polymerases α, δ, and ε. DNA polymerase α, an heterotetramer composed of two primase subunits and two polymerase subunits, initiates replication. DNA polymerases δ and ε elongate the primers generated by pol α. The DNA polymerase from bacteriophage RB69 has served as a model for eukaryotic B family polymerases for some time. The recent crystal structures of pol δ, α, and ε revealed similarities but also a number of unexpected differences between the eukaryotic polymerases and their bacteriophage counterpart, and also among the three yeast polymerases. This review will focus on their shared structural elements as well as the features that are unique to each of these polymerases.

Air-coupled ultrasonic sensing of grass-covered vibrating surfaces; qualitative comparisons with laser Doppler vibrometry (2004)

The paper addresses several sensitive issues concerning the use of air-coupled ultrasound to probe small vibrations of surfaces covered with low-lying vegetation such as grass. The operation of the ultrasonic sensor is compared to that of a laser Doppler vibrometer, in various contexts. It is shown that ambient air motion affects either system, albeit differently. As air speed increases, the acoustic sensor detects a progressively richer turbulent spectrum, which reduces its sensitivity. In turn, optical sensors are prone to tremendous signal losses when probing moving vegetation, due to randomly varying speckle patterns. The work was supported by the Office of Naval Research.
Technique for Analyzing Overlapping Memberships (1972)

Sociologists study the structure or pattern of relationships among individuals and among groups. The sharing of common members is an important relationship, as is the pattern of overlapping members. I will first discuss few instances of sociological concern with the pattern of overlapping memberships in order to clarify the problems that this chapter will solve. The pattern of interlocking directorates among business organizations can give information about the power centralization in a society. Lieberson (1971) suggests that an analysis of the pattern of interlocking directorates among the largest business organizations sheds light on whether the power-elite view or the pluralist view of American society is the more accurate. Lieberson confines himself to a few selected facts (for instance, that the boards of the seven largest New York City banks in 1965 included officials from 51 of the largest 500 industrial companies). Although suggesting the value of a thorough analysis of interlocking directorates, Lieberson does not attempt to provide it.
An Experimental Investigation of the Cross-Coupling between Elements of an Acoustic Imaging Array Transducer (1982)

In a phased array acoustic imaging transducer, the cross coupling between elements of the array can lead to a loss in range resolution, cause an increase in rolloff with angle of the sector scan, and increase the ringdown time. In this paper, we present results of an experimental investigation of an acoustic mode that couples the elements through the propagation of surface waves on the surface of the acoustic absorber. These results indicate that the strength of the mode is enhanced by the coherent reflections from adjacent neighbor elements which act as efficient reflectors of the surface waves. We also demonstrate a technique whereby reflections can be made to interact destructively to reduce the strength of that coupling mode. A further reduction can be obtained by stiffening the structure by bonding to the tops of the elements a thick brass foil and by using it as a common ground connection.

JCPDS—International Centre for Diffraction Data round robin study of silver behenate. A possible low-angle X-ray diffraction calibration standard (1995)

A task group of the JCPDS—International Center for Diffraction Data (ICDD) was established with the charge of investigating the use of silver behenate, CH 3 (CH 2 ) 20 COO·Ag, as a possible low-angle calibration standard for powder diffraction applications. Utilizing several data collection and analysis techniques, long-period spacing ( d 001 ) values with a range of 58.219–58.480 Å were obtained. Using the same collected data and one data analysis refinement calculation method resulted in dm values with a range of 58.303–58.425 Å. Data collected using a silicon internal standard and the same singular data analysis calculation method provided d 001 values with a range of 58.363–58.381 Å.
Bare chip test techniques for multichip modules (2002)

A unique bare-chip test methodology has been developed based upon the GE high-density interconnect (HDI) technology. This methodology allows at-speed testing and screening of complex ASICs (application-specific integrated circuits) and microprocessor chips over the full military temperature range in standard chip-carrier test sockets without any special fixturing or probe cards or in clusters of common chips in a test array. The authors describe the HDI packaging approach and how it is being utilized to perform bare-ship pretest of RAM chips, processors, and complex ASICs and how it can be utilized to provide full preassembly burn-in.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Diastereoselective Electrophilic Fluorination of Enantiopure α-Silylketones Using N-Fluoro-benzosulfonimide: Regio- and Enantioselective Synthesis of α-Fluoroketones (2001)

α-Fluoroketones 6 are synthesized in good yields and high enantiomeric excesses (ee = 87- ≥96%) from the corresponding simple cyclic and acyclic ketone precursors. The procedure involves a regio- and diastereoselective electrophilic fluorination of enantiopure α-silylketones 2 (de = 37-≥ 98%) using commercially available N-fluorobenzosulfonimide as fluorinating agent, followed by a racemization-free cleavage of the silyl directing group with almost quantitative yields.
Navigating the textual redundancy web in legacy source (1996)

Understanding the source, data, and documentation files associated with legacy systems in preparation for maintenance or reengineering is an increasingly important problem for many organizations. A useful tool to support these activities considers the collection of files as text and supports analysis and navigation by exploiting connections that result from the occurrence of exact matches of substrings that derive from the languages used, the design process, the use of common idioms, and maintenance activity. By navigating these paths some understanding of the overall structure can be inferred.A tool for data visualization and navigation of the textual redundancy web based on the technology of HTML and the World Wide Web is described. After an introduction to underlying technology of Analysis of Redundancy in Text and its normalized data model, the entity types are mapped to HTML pages, each of which represents an entity instance and is connected to its neighbours by hypertext links.In order to improve the usefulness of the resulting pages a certain amount of denormalization and careful layout was found to be necessary. The success of this prototype can be attributed to a coming together of well-established ideas from the areas of database design and hypertext document preparation with the new web-based technologies.
Optically controlled delay lines by pulse self-trapping in parametric waveguides with distributed feedback (2000)

Quadratically nonlinear waveguides are studied in the presence of a Bragg grating resonant with one of the involved frequencies. In the case of second-harmonic generation and distributed feedback at the fundamental, we investigate the existence and features of two-color gap-solitary waves, focusing on controlling their propagation speed. This leads to the conception of optically controlled delay lines and retiming schemes for pulse streams in communication systems.
Etching effects during the chemical vapor deposition of (100) diamond (1999)

Current theories of CVD growth on (100) diamond are unable to account for the numerous experimental observations of slow-growing, locally smooth (100)(2×1) films. In this paper we use quantum mechanical calculations of diamond surface thermochemistry and atomic-scale kinetic Monte Carlo simulations of deposition to investigate the efficacy of preferential etching as a mechanism that can help to reconcile this discrepancy. This etching mechanism allows for the removal of undercoordinated carbon atoms from the diamond surface. In the absence of etching, simulated growth on the (100)(2×1) surface is faster than growth on the (110) and (111) surfaces, and the (100) surface is atomically rough. When etching is included in the simulations, the (100) growth rates decrease to values near those observed experimentally, while the rates of growth on the other surfaces remain largely unaffected and similar to those observed experimentally. In addition, the etching mechanism promotes the growth of smooth (100) surface regions in agreement with numerous scanning probe studies.
A STUDY OF THE DECAY PROCESSES OF HUMAN SKELETAL REMAINS FROM THE PARISH CHURCH OF THE HOLY TRINITY, ROTHWELL, NORTHAMPTONSHIRE (1988)

Summary. The 13th century charnel house (or ‘bone crypt') situated underneath the church of the Holy Trinity, Rothwell is one of only two surviving charnel houses in Britain and is therefore important not only in structural terms but also as a reservoir of human osteoarchaeological material. Over the last 60 years concern has been expressed about the condition of the crypt and the ‘deterioration’ of the bones. In this paper the authors outline their multidisciplinary approach to the study of the bone degradation and conditions within the crypt and stress the role of histology in such an approach. The implications of their findings are discussed and action for the long term preservation of the bones are recommended.
Power management for VoIP over IEEE 802.11 WLAN (2004)

Power consumption is a critical issue for voice-over-IP (VoIP) over wireless LAN applications, especially when handheld 802.11 voice terminals are used as the end-user device. This paper provides an overview of power save procedures defined in the IEEE 802.11 wireless LAN standard, and proposes a novel power management technique for stations and services that use contention-based channel access, which we call unscheduled power save delivery (UPSD). We further investigate the performance of UPSD in combination with the eDCA mechanism defined in the 802.11e draft standard via an OPNET-based simulator. The results indicate that UPSD permits a lower duty cycle and delivers better VoIP capacity than legacy techniques.
A new small-size multi-mode and multi-task software radio prototype for future intelligent transport systems (2003)

We have newly developed a small-size software radio terminal that can realize Global Positioning System (GPS), vehicle information and communication system (VICS), electronic toll collection (ETC) system, AM/FM radio broadcasting services, FM multiplex broadcasting system and several modulation schemes such as BPSK, QPSK, GMSK, ASK, and /spl pi//4QPSK by downloading software that realizes each system from wired and wireless networks. The developed terminal realizes simultaneous multiple services when users would like to use several radio communication services in the driving situation by using our proposed multi-task algorithm. The small size and low electrical power consumption of the developed product make it acceptable for consumers such as car drivers. We introduce the configuration and key technologies of our developed terminal and measure the software download and configuration time.
