Fuzzy-Set Social Science

In this innovative approach to the practice of social science, Charles Ragin explores the use of fuzzy sets to bridge the divide between quantitative and qualitative methods. Paradoxically, the fuzzy set is a powerful tool because it replaces an unwieldy, "fuzzy" instrument—the variable, which establishes only the positions of cases relative to each other, with a precise one—degree of membership in a well-defined set. Ragin argues that fuzzy sets allow a far richer dialogue between ideas and evidence in social research than previously possible. They let quantitative researchers abandon "homogenizing assumptions" about cases and causes, they extend diversity-oriented research strategies, and they provide a powerful connection between theory and data analysis. Most important, fuzzy sets can be carefully tailored to fit evolving theoretical concepts, sharpening quantitative tools with in-depth knowledge gained through qualitative, case-oriented inquiry. This book will revolutionize research methods not only in sociology, political science, and anthropology but in any field of inquiry dealing with complex patterns of causation.
A new heuristic for the multi-depot vehicle routing problem that improves upon best-known solutions

SYNOPTIC ABSTRACTIn this paper, the multi-depot vehicle routing problem is reviewed and a new heuristic is presented. The heuristic is fast and simple and improves upon previous best-known solutions. In addition, we generate a variety of new test problems. The new heuristic is shown to perform well on these problems.
Knowledge managing and knowledge management systems in inter-organizational networks

It is argued that the basic economic resource in the new economy is knowledge. An important source for competitive advantage in this economy is organizations' networks of external relationships. It is also argued that information and communication technologies (ICT) and Knowledge Management Systems (KMS) can play an important role in knowledge-intensive processes and flows. This paper presents a conceptualization of strategic knowledge managing within the context of inter-organizational networks. The conceptualization is based on the resource-based, dynamic capability, and absorptive capability views as well as ideas from the ‘gift economy’. Three types of inter-organizational networks for strategic knowledge managing are defined: (1) extra-networks; (2) inter-networks; and (3) open networks. The paper discusses knowledge managing in the three network types and illustrates how ICT and KMS can be used to enable and enhance knowledge managing in inter-organizational networks—the core business process used for illustration is new product development.

A Method of Business Process Modeling Based on Petri Net

Through the analysis of the execution and dispatching principle of the Petri net, the business process management mode based on Petri net is proposed. We merge the place node and the transition node, and reside the token in the node. The only token in process instances and the sub-token in parallel process are introduced, which can avoid conflicts caused by multi-tokens. The business process model for the drawings design and approval is established, and it is verified by the workflow modeling system.

On the Estimation of the Second-Order Statistics of Log Normal Fading in Mobile Radio Environment

It is observed that the estimation of mean signal strength in the mobile radio environment has inherent uncertainties. These may not influence the observed distribution of the mean signal strength but would certainly mask efforts to obtain level crossing rates and duration of fades. A new parameter, duration of stay, is defined which appears to be insensitive to the granular variations of the mean signal strength and would be helpful in the determination of the switching rate in a base station diversity system.
Performance evaluation of the dual signal receiver for a quadrature modulation scheme

The dual signal receiver (DSR) is a narrowband multi-user receiver. Because of its lower complexity and promising results, it can be a valid alternative to CDMA multi-user reception schemes. This paper has three objectives, namely: (i) a presentation of a new realization of the DSR concept, (ii) an investigation of the performance of the DSR with QPSK, and (iii) a comparison of the results for the DSR with QPSK with those of conventional receivers using QPSK and 16-QAM. Under certain conditions, the DSR with QPSK performs more efficiently than the conventional receivers with QPSK and 16-QAM and could therefore represent an effective solution for the spectrum scarcity problems of future mobile communications.
Mapping of spatial distribution of superficial blood vessels in human skin by double correlation analysis of optical coherence tomography images

2D/3D spatial distribution of superficial blood vessels in human skin in vivo was conducted by double correlation analysis of the swept source Optical Coherence Tomography (OCT) images. An adaptive Wiener filtering technique has been employed to remove background noise and increase the overall quality of the OCT images acquired experimentally. Correlation Mapping and Fourier domain correlation approaches have been subsequently applied to enhance spatial resolution of images of vascular network in human skin. The analysis of images performed on Graphics Processing Units (GPUs) utilizing the recently developed Compute Unified Device Architecture (CUDA) framework.

Finally, the experiment illustrates that the new clustering method provides an efficient and effective way for user browsing and locating sought information.
Content analysis of the leading general academic databases

Abstract Title lists from the three leading general academic databases were compared to evaluate journal content. Some of the elements that were analyzed include subject coverage, the quality of titles provided, accessibility issues, and trends over time for these databases. While database title lists are now readily available on the Internet for comparison, as our article illustrates, these lists need further evaluation for proper assessment.
Tree parameter estimation from interferometric radar responses

This paper describes the application of a high fidelity radar scattering model in an inversion process based on a stochastic global search method. Basically, a recently developed coherent scattering model that preserves the structural features of tree canopies using fractal models is employed to generate simplified empirical models (for different tree species) that can predict the polarimetric and interferometric radar response of a forest stand efficiently and accurately. The premise for the successful development of such empirical models stems from the fact that the model outputs are averaged quantities, such as backscattering coefficients or the mean height of the scattering phase center, and therefore are expected to be very gentle functions of model inputs. For the development of the empirical model used in this study, first a sensitivity analysis is conducted in order to determine the significant parameters, the number of which determines the dimensionality of the input vector space. A red pine stand is chosen and six parameters are selected as the input parameters. Each selected parameter is allowed to have about 30% variation with respect to a centroid. Using the Monte Carlo simulation results obtained from fractal-based coherent scattering model (FCSM), a database is constructed by varying the individual parameters over a prescribed range of the input vector space around the centroid. The parameters at the centroid are obtained from the ground truth data of a red pine test stand in Raco, Michigan. For the inversion process, first a least-square estimator is used and is shown to work properly when the number of measured channels is equal to or larger than the dimension of the input vector space. But since this may not be the case in general situations, a genetic algorithm is developed and employed as a search routine for the nonlinear optimization problem.
Compiler generation based on grammar inheritance

The concept of grammar inheritance is introduced. Grammar inheritance is a structural organization of grammar rules by which a grammar inherits rules from ancestor grammars or may have its own rules inherited by descendant grammars. Grammar inheritance supports reusability and extensibility of grammar rules. The concept of grammar inheritance is especially useful in combination with a compiler generator. A compiler generator tool for the SMALLTALK language which supports grammar inheritance is discussed. This tool was implemented on a Sun3 workstation and extensively tested.

Recommendations for future research were provided.
Accordion: An Efficient Gear-Shifting for a Power-Proportional Distributed Data-Placement Method

SUMMARY Power-aware distributed ﬁle systems for e ﬃ cient Big Data processing are increasingly moving towards power-proportional designs. However, current data placement methods for such systems have not given careful consideration to the e ﬀ ect of gear-shifting during operations. If the system wants to shift to a higher gear, it must reallocate the updated datasets that were modiﬁed in a lower gear when a subset of the nodes was inactive, but without disrupting the servicing of requests from clients. Ine ﬃ cient gear-shifting that requires a large amount of data reallocation greatly degrades the system performance. To address this challenge, this paper proposes a data placement method known as Accordion , which uses data replication to arrange the data layout comprehensively and provide ef-ﬁcient gear-shifting. Compared with current methods, Accordion reduces the amount of data transferred, which signiﬁcantly shortens the period required to reallocate the updated data during gear-shifting then able to improve the performance of the systems. The e ﬀ ect of this reduction is larger with higher gears, so Accordion is suitable for smooth gear-shifting in multigear systems. Moreover, the times when the active nodes serve the requests are well distributed, so Accordion is capable of higher scalability than existing methods based on the I / O throughput performance. Accor-dion does not require any strict constraint on the number of nodes in the system therefore our proposed method is expected to work well in practical environments. Extensive empirical experiments using actual machines with an Accordion prototype based on the Hadoop Distributed File System demonstrated that our proposed method signiﬁcantly reduced the period required to transfer updated data, i.e., by 66% compared with an existing method.
Using transaction log analysis to assess student search behavior in the library instruction classroom

Purpose – The purpose of this study is to determine how undergraduate students search in the context of a library instruction session. The results of an assessment of transaction logs are shared to provide evidence of student search behavior within a class setting. Design/methodology/approach – Transaction logs from 29 library instruction sessions using the library’s federated search tool were analyzed. Using a rubric, the authors assessed the logs to discover if students followed the instruction provided to construct more relevant, targeted searches, if they selected recommended resources and if they exhibited persistence in their searching. Findings – The study found most students had difficulty translating instruction on how to use quotation marks into their own searches, were mostly successful when choosing a database and notes varying participation patterns in classes taught at different times. Practical implications – Implications of this study include greater awareness of student search behaviors d.
A bandpass filter using the operational amplifier pole

The pole of an operational amplifier and a grounded capacitor are used for obtaining a high Q bandpass function. The utilization of the pole of the operational amplifier enables the extension of its useful frequency range. The gain and the bandwidth of the operational amplifier are the primary factors determining the filter performance. The experimental results of a low-sensitivity filter circuit are presented. The circuit is suitable for integration.
Research on HLA Optimistic Time Advance Mechanism Based on FQR

With the widely application of High Level Architecture (HLA) standard that supports interoperability and reusability, correct understanding of time management and advance mechanism in HLA has been a concerning difficult problem in the field of distributed simulation. Aiming at the problem, the paper analyzed and compared difference between conservative time advance mechanism and optimistic time advance mechanism. The rollback manager was introduced to implement the optimistic time advance mechanism. The middleware was also applied to deal with the rollback process in simulation model. In order to make fully use of advantages of optimistic synchronization mechanism, Flash Queue Request (FQR) service that provided by HLA was used to arrive at an improved time advance algorithm.
Fredholm and Volterra integral equations of the second kind

Integral equations are often the best way to formulate physics problems. However, the typical physics student gets almost no training in integral equations, in contrast to differential equations, for example. Many physicists thus believe that numerical solution of integral equations must be an extremely arcane topic, since it is almost never dealt with in numerical analysis textbooks!
Investigation On A Haptic Display System ForMedical Ultrasonic Elasticity Imaging

In the field of medical ultrasonics, ultrasonic elasticity imaging has been developed and used in practical diagnosis. However, unfortunately, elasticity information is now displayed on ordinary 2D screens (for example, CRT). Since elasticity information is haptic information, not visible information, the information is expected to be displayed in “the sense of haptic”. In this research, it is attempted to display this elasticity information on a haptic display. In this system, a target tissue is expressed by many small cubes in 3D virtual space. Each cube has its own elasticity information. When a cube is pressed, not only the cube but some cubes around it are simultaneously moved in the direction of the pressure, but if the pressure disappears, the cubes come back to their original position. This movement of cubes can express a dent in the surface of the body. At that time we can feel haptic sense from the pressed point, which is caused by the mass and elasticity of some cubes around the pressed point. This newlydevised system enables to put the haptic sense to close “Human Haptic”. The system also enables one to display the haptic sense in real time after getting elastic information of tissues. This system can realize a virtual palpation system and may realize a tele-palpation system.
On translating picture books

Abstract Despite their effect on the reader, illustrations are often overlooked in translation work. Moreover, the problems of the visual attract little attention from scholars in the field, even though translators often have to deal with the visual, e.g., in literary, technical, and media translation. Visual literacy is also overlooked in translator training. This article deals with the visual in translation from one viewpoint: that of translating picture books. The author discusses picture books as iconotexts, unities formed by words, images, and effects. In picture books, there is interaction between two semiotic systems, one verbal and the other visual. The starting point is that translation is rewriting for different audiences in different situations. The author considers the translation of the visual within the wider frame of hermeneutics and uses semiotics in analyzing iconotexts. The article is based on two of her books: Translating for Children (2000) and the forthcoming Kuva kääntäjän kädessä ("Translating the Visual)).
Performance Optimization Study of FinFETs Considering Parasitic Capacitance and Resistance

Recently, the first generation of mass production of FinFET-based microprocessors has begun, and scaling of FinFET transistors is ongoing. Traditional capacitance and resistance models cannot be applied to nonplanar-gate transistors like FinFETs. Although scaling of nanoscale FinFETs may alleviate electrostatic limitations, parasitic capacitances and resistances increase owing to the increasing proximity of the source/drain (S/D) region and metal contact. In this paper, we develop analytical models of parasitic components of FinFETs that employ the raised source/drain structure and metal contact. The accuracy of the proposed model is verified with the results of a 3-D field solver, Raphael. We also investigate the effects of layout changes on the parasitic components and the current-gain cutoff frequency (fT). The optimal FinFET layout design for RF performance is predicted using the proposed analytical models. The proposed analytical model can be implemented as a compact model for accurate circuit simulations.
The SPARC water vapour assessment II: profile-to-profile comparisons of stratospheric and lower mesospheric water vapour data sets obtained from satellites

Abstract. Within the framework of the second SPARC (Stratosphere-troposphere Processes And their Role in Climate) water vapour assessment (WAVAS-II), profile-to-profile comparisons of stratospheric and lower mesospheric water vapour were performed by considering 33 data sets derived from satellite observations of 15 different instruments. These comparisons aimed to provide a picture of the typical biases and drifts in the observational database and to identify data-set-specific problems. The observational database typically exhibits the largest biases below 70 hPa, both in absolute and relative terms. The smallest biases are often found between 50 and 5 hPa. Typically, they range from 0.25 to 0.5 ppmv (5 % to 10 %) in this altitude region, based on the 50 % percentile over the different comparison results. Higher up, the biases increase with altitude overall but this general behaviour is accompanied by considerable variations. Characteristic values vary between 0.3 and 1 ppmv (4 % to 20 %). Obvious data-set-specific bias issues are found for a number of data sets. In our work we performed a drift analysis for data sets overlapping for a period of at least 36 months. This assessment shows a wide range of drifts among the different data sets that are statistically significant at the 2σ uncertainty level. In general, the smallest drifts are found in the altitude range between about 30 and 10 hPa. Histograms considering results from all altitudes indicate the largest occurrence for drifts between 0.05 and 0.3 ppmv decade−1. Comparisons of our drift estimates to those derived from comparisons of zonal mean time series only exhibit statistically significant differences in slightly more than 3 % of the comparisons. Hence, drift estimates from profile-to-profile and zonal mean time series comparisons are largely interchangeable. As for the biases, a number of data sets exhibit prominent drift issues. In our analyses we found that the large number of MIPAS data sets included in the assessment affects our general results as well as the bias summaries we provide for the individual data sets. This is because these data sets exhibit a relative similarity with respect to the remaining data sets, despite the fact that they are based on different measurement modes and different processors implementing different retrieval choices. Because of that, we have by default considered an aggregation of the comparison results obtained from MIPAS data sets. Results without this aggregation are provided on multiple occasions to characterise the effects due to the numerous MIPAS data sets. Among other effects, they cause a reduction of the typical biases in the observational database.
