Manipulation of microparticles with ultrasound acoustic waves

The goal of the experiment is to concentrate microparticles and move them to a specific place in water using ultrasound waves. The principle behind this experiment is the difference in compressibility of the microparticles and the water. Due to this difference a radial force drives the particles to a certain position. Through applying two different, but close, frequencies a kind of travelling standing wave can be produced so that the particles are moved across the flow channel, captured inmoving pressure nodes. Unfortunately it was quit hard to build the flow channel and to find an appropriate way of connecting the piezoelectric elements, such that the goals were not completely met. In the time available it was showed that it was possible to make standing wave patterns in the flow channel. The used 20 ¹mpolystyrene particles would align at the nodes of the waves and formrows of particles. Possible improvements can be made in the formof a feedback system to be able to make a perfect absorption of the reflected wave. In this report a detailed description of the steps that are taken to achieve the goal of the experiment is included.
Experiments with toroidal microresonators in cavity QED

Advances made pertaining to strong interactions between single photons of light and single atoms have great potential in the field of quantum information. However, scalability is a limiting factor in the applicability of current technologies (such as an atom in the mode of a Fabry-Perot resonator) due to difficulties in alignment and fabrication. Toroial resonators, however, are fabricated lithographically on silicon wafers, and are therefore easily scalable. Light is coupled into a toroid by tapered optical fiber, allowing for the efficient retrieval of photons from the resonator mode that is necessary if multiple resonators are to be eventually coupled to one another. We have demonstrated interactions between single atoms of cesium and a toroidal resonator that lie in the regime of strong coupling since the rate of coupling between an atom and the cavity mode, g0 m = (50±12) MHz, is much larger than the dissipative rates of the system (gamma, kappa)/2pi ~ (2.6, 18) MHz. To further expand upon the usefulness of toroids in cavity QED, I have striven to improve the way that toroids are characterized and coupled. An apparatus which semi-automates the characterization process reduces the length of time a toroid is outside of vacuum, thus limiting environmental degradation. To help in better understanding the process of pulling tapered fibers, the efficiency and characteristic quantities have been detailed. Similarly, the behavior of a toroid resonance as a function of coupling strength was quantified. Preliminary locking of the coupling by controlling the separation between the taper and toroid has been accomplished. This locking will allow the next generation of atom-toroid coupling to require less human intervention and therefore be more efficient.
Classification and fertility status of soils on slopes of varying orientations in Umuahia area of Abia State, Nigeria

The slope orientation and position of toposequence influence soil properties along the landscape. The study classified and evaluated the fertility status of soils on slopes of varying orientations in Umudike (East-lying Toposequence) and Itu (West-lying Toposequence) located in Olokoro Umuahia, Abia State southeastern Nigeria. Transect soil sampling technique was employed in locating 3 distinct top units (Summit, Midslope and Footslope) along each of the toposequence. Soil profile pit was dug at each top unit, described using FAO guidelines and sampled according to genetic horizons. Soil samples collected were subjected to routine laboratory analyses. Pedons were classified using the USDA Soil Taxonomy System and correlated with World Reference Base while the fertility status was evaluated using elemental ratios. The results indicated that soils of the two toposequence were dominated by sandy clay loam texture. Consistency of the pedons generally varied from very friable (Vfr) to very firm (Vfi) in the two toposequence. Soil pH was very strongly acidic (4.58-4.78) in the east lying toposequence but varied from very strongly acidic to strongly acidic (4.52-5.30) in the west lying toposequence. Organic matter concentration was higher at the epipedons and ranged from 26.44 to 23.36 g kg -1 and 18.9 to 30.64 g kg -1 in soils of east-lying and west-lying slopes, respectively. K: Mg ratio varied from 0.01- 0.12 and 0.01-0.08 at the east and west lying slopes, respectively. The pedons of the summit, midslope and footslope were as classified Grossarenic Paleudalfs, Typic Paleudalfs and Arenic Hapludalfs for respectively for the east-lying slope and Arenic Glossudalfs, Typic Paleudalfs and Typic Ferrudalfs, respectively for the west-lying slope. Generally, the two toposequences were of poor fertility status.
Breast Cancer Classification: A CAD System for a Combined Use of Elastography and B-Mode Sonography

Purpose: The aim of this study was to evaluate and compare the diagnostic performance of elastography, B-mode Ultrasound (US), and a combination of elastography and B-mode US for the differentiation between benign and malignant lesions. Methods: A prospective study was carried out from July to December 2015, which 87 patients with 83 lesions were examined with conventional B-mode ultrasound and strain elastography. All the lesions had been proven by biopsy, resulting in 31 malignant and 52 benign lesions. A radiologist with 16 years of experience classified visually these cases. We also used a CAD sys-tem to classify the lesions classified visually by the most experienced radiologist and using a CAD system. The data obtained were compared with the results provided by another radiologist and a resident with 2 years of experience. Sensitivity, specificity and AUC for the three observers using the CAD system were calculated. Results: The developed CADx system provided a diagnostic concordance in the classification of breast lesions from the different ways of contour determination (manual and automatic), allowing to reduce the diagnostic variability. In addition, the CADx system showed superior results to the visual analysis of the radiologist. When the radiologist associated both examinations (B-mode ultrasound and elastography), his visual analysis provided 87.1%, 55.8% and 0.714 of sensitivity, specificity and AUC, respectively. When we considered the result provided by the association between B-mode ultrasound and elastography images, the CADx system provided a comparative increase of about 7% of sensitivity and 17.2% of specificity, using the contour delimited by the most experienced radiologist. In addition, a positive influence was observed in the use of the computational tool by radiologists, since, on average, their sensitivity and specificity indexes also increased in relation to the conventional analysis, from 87.1% and 55.8% to 90.3% and 73.1%, respectively. Conclusion: Thus, it can be concluded that the developed CADx system performed well in distinguishing benign from malignant lesions for both B-mode ultrasound and elastography. The AUC obtained was higher than the radiologist’s visual analysis in most of the cases analyzed. Citation: Marcomini KD, Fleury EFC, Schiabela H.

EFFI-CNN uses lung CT scan images from LIDC-IDRI and Mendeley data sets. EFFI-CNN has a unique combination of CNN layers with parameters (Depth, Height, Width, filter Height and filter width).
CREATIVE EVOLUTIONARY SYSTEMS

The use of evolution for creative problem solving is one of the most exciting and potentially significant areas in computer science today. Evolutionary computation is a way of solving problems, or generating designs, using mechanisms derived from natural evolution. This book concentrates on applying important ideas in evolutionary computation to creative areas, such as art, music, architecture, and desgn. It shows how human interaction, new representations, and approaches such as open-ended evolution can extend the capabiities of evolutionary computation from optimization of existing solutions to innovation and the generation of entirely new and original solutions. This book takes a fresh look at creativity, exploring what it is and how the actions of evolution can resemble it. Examples of novel evolved solutions are presented in a variety of creative disciplines. The editors have compiled contributions by leading researchers in each discipline.
Modeling of Impulse Noise for Indoor Broadband Power Line Communications

@imc.cce. i.kyoto-u.ac. jpAbstractResidential power line is one of the most attractive com-munication media for in-home networking, since almost allrooms in a house have power outlets. The regulations onpower line communication (PLC) may be eased in Japanand we could utilize a frequency band from 2 to 30MHzin the future. However, many electrical appliances and/orshortwave systems frequently cause man-made electromag-netic interference on indoor power line. This man-madenoise often has impulsive characteristics. We will extendknowledge about impulse noise at indoor power line in thefrequency range from 2 to 30MHz. We measure indoorpower line noise in several environments and apply a de-tection method by chi-square test to the measured noise.Further we model the amplitudes, durations, and interar-rival time of indoor power line impulses. These impulsenoise models are expected to utilize for communication de-sign about PLC.1. INTRODUCTIONIn-home PLC is getting so much attention for in-homenetworking, since almost all rooms in a house have poweroutlets. Therefore a relaxation of the regulations on PLC isdiscussed and we could utilize a frequency band from 2 to30MHz in the future. However many electrical appliancesand/or shortwave systems frequently cause man-made elec-tromagnetic noise on indoor power line. This man-madenoise often has impulsive characteristics. The statisticalmodel of impulse noise helps us a great deal for the designof reliable communication. Therefore many statistical stud-ies of impulse noise have been done not only for PLC [1–3]but for wireless communication [4,5] and digital subscriberline (DSL) [6,7]. As an early work, Chan and Donaldson investigated thestatics of indoor power line impulse noise [1]. However,their investigation is restricted to the frequency range be-low 200kHz. Zimmerman and Dostert extended the knowl-edge about power line impulse noise in the frequency rangefromsomehundredkHzupto20MHz[2,3]. Theyclassiﬁedpower line noise into ﬁve category as follows:(1) colored background noise,(2) narrowband noise,(3) periodicimpulsenoiseasynchronoustothemainsfre-quency,(4) periodic impulse noise synchronous to the mains fre-quency, and(5) asynchronous impulse noise.Furthermore,theyproposedastatisticalmodelfordurationsand interarrival times of the asynchronous impulse noise.However, their analysis and modeling was for access PLC,they did not provide any statistical model for amplitudes ofthe impulse noise, and their modeling cannot be applied tohigh speed PLC as the minimum unit of impulse durationswas 80
Computational Modelling of Suspect Behaviour in Police Interviews

Simulating human behaviour in virtual persona's is an important step to create realistic virtual agents. As part of building a police interview training simulation system, a response model for suspect behaviour is created. This model is based on theory gathered in several ways. The model uses abstract factors like stance, rapport and strategies as input, updates the internal state of the system and provides a response in abstract factors such as answer type (lie/truth), answer length and friendliness. This model was validated through a user experiment in which participants acted as police officers interviewing a suspect. The experiment showed that the model provided more realistic behaviour than random output generation would and that predefined persona's were recognized 81% of the time. The response model can be used in future work to act as the decision making unit for a suspect agent in a interview training simulation.
Stars vs. Underdogs in Online Music Markets: The Effect of IT on Visibility, Artists’ Broadcasting, and Fans’ Activities

In cultural markets, for books, music or movies, sales are concentrated on a small number of highly successful products. One explanation for the skewness of sales is incomplete information: consumers are poorly informed about most products, because only a small proportion of them are visible and promoted in the offline world. With digitization, as suggested by the Long Tail hypothesis, the increasing visibility of niche products could improve consumer information, and thus reduce sales concentration. In this paper, we study whether, in the music industry, online promotion improves the visibility of “underdog” artists or that of “stars”. We use an original and large dataset of indicators for visibility, both offline (i.e., press coverage) and online (e.g., Facebook, Twitter, MySpace, YouTube, or LastFm), for about 1,000 artists over a 6-month period following a new album release. First, we investigate the extent to which the Internet democratizes access to visibility, and we examine the online promotional actions taken by artists and their fans to overcome a potential lack of visibility. We find that, while the most popular and visible artists offline are also the most visible online, audiences of underdog and debut artists are more strongly engaged to support their promotion efforts. Then, we use a panel vector autoregression (PVAR) model to explore the interplay between artists’ broadcasting activities (artist-generated content), fans’ activities (user-generated content), artists’ online reputation (number of fans) and a free form of online consumption (music streaming), according to the artist’s visibility in the traditional media channels. Our main results suggest that the promotion supported by online audiences has a positive effect on music streaming only for underdog artists, whereas artists’ broadcasting activities in social media have no direct impact on music streaming.
Questioning the future of paper and online survey questionnaires for management research

The way that we build the foundations of our intellectual capital in management has changed. One example is the steady move in management research from the use of traditional paper-based survey questionnaires to online technology-based formats. This paper considers this shift, particularly focusing on the question of whether the advantages of online survey questionnaires outweigh their potential problems. The historical use of paper-based survey questionnaires has produced a large body of literature on both the advantages and disadvantages in their use, which are reviewed here alongside those of online survey questionnaires. In addition, welI-tested methods are available for increasing survey response rates in paper format, and these should not be thrown out in the quest to utilise online survey methodology. Rather, researchers should aim to exploit the potential benefits of online technologies and increase response rate by thoughtfully combining traditional and new methods. This paper argues for further discussion and research attention on electronic methods of data collection to ensure potential cost savings are not outweighed by either financial or participation costs involved in online survey questionnaire design.
Revisiting the modified Baermann extraction method: extraction efficiency of Radopholus similis using different extraction materials

we used Radopholus similis as a species with both male and female adults, both of which are motile, and to which we had access from in vitro cultures. The experiment evaluated four key variable factors that may potentially affect extraction efﬁciency of R. similis , in a randomised complete block design with four replications and conducted three times. The four factors include: soil type (red ferralitic soil and sand), tap water volume (200 and 400 ml), soil quantity (50 and 100 ml) and ﬁlter types (19-cm-diam. milk ﬁlter (GD Textile Manufacturing), two-ply Kleenex facial tissue (Kim-Fay) and two-ply Velvex kitchen paper towel (Chandaria Industries)). The experimental unit was an individual modiﬁed Baermann plate receiving either one of the 24 treatment combinations of the four factors. Each experiment consisted of 96 samples in total. The red ferralitic soil is a common soil type in Kenya, consisting of 83.3% clay, 7.7% silt and 9.0% sand; local river sand comprised 3.2% clay, 1.9% silt and 95% sand.
Genset-Solar-Wind Hybrid Power System of Off-grid Power Station for Rural Applications

A hybrid power system (HPS) which consists of diesel Genset, PV-arrays and wind turbines with energy storing and power electronic devices is discussed in this paper. An inventory of different connection topologies is made for some of the sources generate AC power and others generate DC power. By comparative study on the system efficiency, the Mixed-coupled HPS is found to be the best layout and this layout is used for further investigation. By considering AC-load demand, solar irradiation and wind speed profiles of a typical site, the sizing approaches of the system elements are developed for the HPS. For the selected layout, eleven innovative Power Management Strategies (PMSs) are defined; and for each PMS Mathematical models are derived based on the power balance between the supply and the demand sides, charging/ discharging control of the battery and switching controls for the Genset. The different HPSs are modeled using MATLAB/Simulink blocks and simulation results are analyzed. The different PMSs result to different sizing of system elements, power sharing, fuel consumption& environmental impacts, and cycles of batteries in the lifetime of the system. Finally, the hybrid system of each PMS is investigated for its cost competitiveness and environmental impacts by taking the economical aspects and fuel consumption into consideration. It is found that RESs and/or HPSs are cost competitive over the system life, in spite of the huge initial capital costs, for the variable costs of the Genset overshadows its low initial capital investment .
Macroscopic and microscopic variation of iron and high carbon steel production in the Southern Highlands of Tanzania

One essential feature of African iron production process is that it is greatly variable in culture and technology. The early research focused on some themes: origins, culture, and how iron was produced, which were investigated using archaeological, ethno-archaeological, and experimental methods. The purpose of this thesis was to examine the relationship between macroscopic and microscopic variation of iron and steel production in the southern highlands of Tanzania. I used field methods: ethnographic inquiry, surface and sub-surface survey, mapping, and excavation; and laboratory analytical techniques: firing, optical and electron microscopy, microanalysis, and X-ray fluorescence to investigate the research theme. The results indicate that there is a strong relationship between macro- and microscopic variation of iron and steel production in terms of the use technical ceramics with good refractory qualities, the presence of the three stage process in Ufipa and Unyiha, involving a refining stage between the smelting and smithing stages; the liquid slag handling techniques, the reduction efficiency, and the nature of the final products: soft iron and carbon-rich steel. Although there are macroscopic data on the use of forced- and natural-draft furnaces in the region, it is difficult to microscopically verify the air supply mechanisms in the region. This work recommends that in order to avoid the confusion on the three stage process and relationship between macro- and microscopic variation in iron and steel production, the role of matrix and provenance should be given due weight as laboratory analyses.
