Chucking the Checklist: A Contextual Approach to Teaching Undergraduates Web-Site Evaluation

This paper criticizes the checklist model approach (authority, accuracy, objectivity, currency, coverage) to teaching undergraduates how to evaluate Web sites. The checklist model rests on faulty assumptions about the nature of information available through the Web, mistaken beliefs about student evaluation skills, and an exaggerated sense of librarian expertise in evaluating information. The checklist model is difficult to implement in practice and encourages a mechanistic way of evaluating that is at odds with critical thinking. A contextual approach is offered as an alternative. A contextual approach uses three techniques: promoting peer- and editorially-reviewed resources, comparison, and corroboration. The contextual approach promotes library resources, teaches information literacy, and encourages reasoned judgments of information quality.
Simplified control of FFT hardware

A particularly simple way to control fast Fourier transform (FFT) hardware is described. The method produces the indices both for inputs of each butterfly operation and for the appropriate W. In addition, this method allows parallel organization of the memory such that at any stage the two inputs and outputs of each butterfly belong to different memory units, hence can always be accessed in parallel.
Mobile Search - Social Network Search Using Mobile Devices Demonstration

Mobile search prototype demonstrates the possibilities of social network search in N800 mobile devices. Search is initiated from a N800 mobile device to search the contacts in mobile device's addressbook. The contacts can be other N800 mobile devices running mobile Web server or normal Web servers in the Internet with Drupal content management system. Mobile device users can select which of their personal information such as phone numbers, calendar data etc. to share via a mobile Web server. The proposed search mechanism has many benefits compared to centralized Web search engines like Google. The search can locate information which is not referenced anywhere and thus allows hidden or rare information to be found. The search is executed realtime and does not provide outdated links. The search is directed to persons close in the social network and thus provides results which are more likely to be relevant to the querier. However, for searching popular data accessible via centralized servers mobile search is not well suited.
Content representation in document titles: a case study with prostaglandin literature

A total of 2,792 document titles published in a specialized subject bibliography entitled The Prostaglandins by the Upjohn Company, USA, was examined. There was a slight but significant increase in information content of the titles with time. Employing the Montgomery‐Swanson method, it was found that about 80 per cent of the papers had at least one ‘prostaglandin‐term’ in their titles. The data obtained in this study are compared with those obtained in earlier studies.
A Comparative Study of Rotational and Stereoscopic Computer Graphic Depth Cues

The present research investigated the effectiveness of rotational and stereoscopic display techniques as applied to practical applications in computer graphics. In the described experiments, depth perception was evaluated by examining accuracy in a 3D path-tracing task, with stimulus displays resembling the structure of cerebral angiograms. In the first experiment, task performance was determined without 3D enhancements, with either technique used alone and with both techniques combined. The results indicated that performance improved using either technique, however, performance with rotational displays was superior to stereoscopic displays, and performance was best when both techniques were combined. The results of a second experiment revealed that rotational displays were no better than stereoscopic displays enhanced with multiple static viewing angles. The experimental findings are discussed in terms of the visual information available using either 3D display technique as well as with respect to the hardware requirements of both display systems. The results are also related to the weighted additive model of depth perception.
Challenges and Methods of International Census Harmonization

Abstract The development of IPUMS-International involves harmonizing data from different national statistical offices created over several decades. The original samples vary in quality and have different data formats and variable coding schemes. The authors describe the methods developed to deal with the challenges posed by such diversity and unevenness. The first stage of harmonization involves standardizing the data formats and correcting errors. Diagnostic routines analyze each data set, and custom computer programs modify the different data structures into a single standard format. The second stage of the work centers on harmonizing the codes for all variables shared across data sets, including the compilation and integration of all the relevant documentation.
Discriminatively trained part based model armed with biased saliency

Discriminatively trained Part based Model (DPM) is one of the state-of-the-art object detectors. However, DPM complies little with real vision procedure. In this paper, we try arming DPM with biologically inspired approaches. On the one hand, we use Gabor instead of Histogram of Oriented Gradient (HOG) as low level features to simulate the receptive fields of simple cells. We show Gabor outperforms or is on par with HOG. On the other hand, we learn biased saliency of the object with the same Gabor features to simulate the search procedure of real vision. We combine DPM and biased saliency in a single Bayesian framework, which at least partially reflects the interactions between top-down and bottom-up vision procedures. We show these biologically inspired procedures can effectively improve the performance and efficiency of DPM. We present experimental results on both challenging PASCAL VOC2007 dataset and publicly available sequences.
A Hypermap Approach to Multiple Sequence Processing

Abstract A self-organizing neural network that learns and recalls multiple sequences is presented. Each of the sequences may have recurring items, and several sequences may have one or more common items. The self-organizing temporal network stores each sequence independently of other sequences, and the learning of a sequence does not necessitate a retraining of the network on previously learnt sequences. An experimental assessment using a benchmark set of sequences suggests that the network recalls stored sequences in their intact form when presented with their sequence identity vectors or when presented with their constituent subsequences. The utility of the proposed temporal network, which also exhibits multimodality, is demonstrated by incorporating the network into a gated multinet model of early child language development.
Volumetric medical image compression with three-dimensional wavelet transform and octave zerotree coding

Compression of 3D or 4D medical image data has now become imperative for clinical picture archiving and communication systems (PACS), telemedicine and telepresence networks. While lossless compression is often desired, lossy compression techniques are gaining acceptance for medical applications, provided that clinically important information can be preserved in the coding process. We present a comprehensive study of volumetric image compression with three-dimensional wavelet transform, adaptive quantization with 3D spatial constraints, and octave zerotree coding. The volumetric image data is first decomposed using 3D separable wavelet filterbanks. In this study, we adopt a 3-level decomposition to form a 22-band multiresolution pyramid of octree. An adaptive quantization with 3D spatial constraints is then applied to reduce the statistical and psychovisual redundancies in the subbands. Finally, to exploit the dependencies among the quantized subband coefficients resulting from 3D wavelet decomposition, an octave zerotree coding scheme is developed. The proposed volumetric image compression scheme is applied to a set of real CT medical data. Significant coding gain has been achieved that demonstrates the effectiveness of the proposed volumetric image compression scheme for medical as well as other applications.
A data set for fuzzy colour naming

Although colour naming has been studied from different points of view, the automation of this visual task has not been an active topic until recently. In computer vision, colour naming has been posed as a fuzzy-set problem where each colour category is modelled by a function that assigns a membership value to any given sample. However, the success in the automation of this process relies on having an appropriate psycho-physical data set for this purpose. Up to the present, such a dataset has not been available. In this paper we present a data set obtained from a colour-naming experiment. In this experiment, we have used a scoring method to collect a set of judgements adequate for the fuzzy modelling of the colour-naming task. The data set is composed of 387 colour reflectances, their CIELab and Munsell values, and the corresponding judgements provided by the subjects in the experiment. These judgements are the membership values to the eleven basic colour categories proposed by Berlin and Kay 1 . All these data have been made available online (http://www.cvc.uab.es/color_naming) and, in this paper we provide a wide analysis of it. To prove the suitability of the proposed scoring methodology, we have computed a set of common statistics in colour-naming experiments, such as consensus and consistency, on our dataset. The results make us to conclude the coherence of our data with previous experiments and, thus, its usefulness for the fuzzy modelling of colour naming.
Application of Acrylates in Enhanced Oil Recovery

Currently, enhanced oil recovery (EOR) acquire increased attention to recover more residual oil trapped after the primary and secondary process in petroleum reservoirs. EOR comprise different technologies involving chemical, thermal, miscible flooding techniques. Chemical flooding by the polymer is a widely implemented method on the academic and industrial scale. In this chapter, the authors discuss polymer flooding using polyacrylates that involve hydrolyzed polyacrylamide (HPAM), hydrophobically associated polyacrylamides (HAPAM), which grafted with different vinyl monomers such as acrylic acid, methyl methacrylates, and 2-acrylamido-2-methylpropane sulfonic acid (AMPS). These polymers increase the viscosity of injected brine solutions, as a result, decrease mobility ratio and enhance sweeping efficiency, so the water act as a piston, which pushes oil in front of it, and consequently increase the recovery factor. The advantages and disadvantages of these polymers as well as comparing different flooding scenarios are reported. DOI : 10.14302/issn.2377-2549.jndc-18-1933 Corresponding author: A.N.

Convolution algebras and the deformation theory of infinity-morphisms

Given a coalgebra C over a cooperad, and an algebra A over an operad, it is often possible to define a natural homotopy Lie algebra structure on hom(C,A), the space of linear maps between them, called the convolution algebra of C and A. In the present article, we use convolution algebras to define the deformation complex for infinity-morphisms of algebras over operads and coalgebras over cooperads. We also complete the study of the compatibility between convolution algebras and infinity-morphisms of algebras and coalgebras. We prove that the convolution algebra bifunctor can be extended to a bifunctor that accepts infinity-morphisms in both slots and which is well defined up to homotopy, and we generalize and take a new point of view on some other already known results. This paper concludes a series of works by the two authors dealing with the investigation of convolution algebras.
Controlled accuracy approximation of sigmoid function for efficient FPGA-based implementation of artificial neurons

A controlled accuracy approximation scheme of the sigmoid function for artificial neuron implementation based on Taylor's theorem and the Lagrange form of the error is proposed. The main advantages of the proposed solution are two: it provides a systematic way to guarantee the required accuracy and it reuses the circuitry of the linear part of the neuron to compute the sigmoid function. The sigmoid derivative is also available for artificial neural networks with online learning capabilities.
Performance of the multi-stage detector for a MC-CDMA system in a Rayleigh fading channel

Multi-carrier (MC) CDMA is a multiple access scheme that combines multi-carrier modulation (or OFDM) with direct sequence spread spectrum (DS-SS), and allows for efficient utilization of the bandwidth, resistance against frequency selectivity inherent in broadband mobile radio channels, and efficient implementation using the FFT. Since the complexity of the optimum maximum likelihood detector (MLD) grows exponentially with the number of users, simpler suboptimum detectors are considered in practical applications. We analyze the performance of a new form of the multi-stage detector using the threshold orthogonality restoring correlation (TORC) detector at the initial stage, in a frequency selective, slowly fading Rayleigh channel. Analytical and simulation results are presented for the initial stage (TORC detector) and the first stage of the multi-stage detector, which show that with only one stage significant performance enhancement can be achieved.
Library services for the future: engaging with our customers to determine wants and needs

Purpose – Like any other customer‐centred organisation, the library has a variety of methods at its disposal to gather information from and about its customers, such as usage data, survey results, focus groups, and face‐to‐face opportunistic encounters. Given that using survey instruments is currently the main way that libraries engage with their customers this paper seeks to look at how librarians can ensure that their surveys are of the best possible quality. It then aims to present two case studies.Design/methodology/approach – The paper discusses successful methods for engaging customers, both online and in person, in conversation with particular reference to new generation learners, and the need to demonstrate to participants that their opinions are heard and have an impact. The paper then discusses two case studies of work undertaken at Victoria University of Wellington Library. In the first case the Library sought student participation and input to Te RōpŪ Whakamanawa, a working group convened to a.
Sonority, gender and the impact of suffix predictability on the acquisition of German noun plurals

The acquisition of German noun plurals has been the topic of many studies and of much controversy. This study presents a new method of assessing distributional properties of plural suffix application in German in which the predictability of a given suffix (-s, -(e)n, -e, -er or zero) is calculated according to sonority/gender distributions in actual language use, in our case, in child-directed speech. The relevance of suffix predictability is tested in 140 Viennese children from the age of three to nine years by means of a plural elicitation task. Results show that suffix predictability has an impact on children’s correct and erroneous production of plural suffixes. The results are compatible with a usage-based variant of the single-route view which emphasizes speakers’ preference for local generalizations and the role of neighbourhood density in generalization.
Efficient evolutionary optimization through the use of a cultural algorithm

This paper introduces a cultural algorithm that uses domain knowledge to improve the performance of an evolutionary programming technique adopted for constrained optimization. The proposed approach extracts domain knowledge during the evolutionary process and builds a map of the feasible region to guide the search more efficiently. Additionally, in order to have a more efficient memory management scheme, the current implementation uses 2 n -trees to store this map of the feasible region. Results indicate that the approach is able to produce very competitive results with respect to other optimization techniques at a considerably lower computational cost.
Fostering Language Teaching Efficiency through Cognitive Linguistics

In contexts of instructed second language acquisition there is a need for teaching methods that are optimally efficient, i.e. teaching interventions that generate a maximal return on learners' and teachers' investment of time and effort. In the past couple of decades, many researchers have argued that insights from Cognitive Linguistics (CL) - when suitably translated for pedagogical purposes - can make a major contribution to fostering such language teaching efficiency. This collective volume assesses and supplements those CL proposals. The first part of the book positions CL-inspired language pedagogy vis-a-vis recent trends in mainstream applied linguistics and illustrates through several case studies that language-focused instruction (including CL-inspired instruction) is a useful - if not indispensable - complement to learner-autonomous, incidental acquisition. The second part demonstrates how CL research can help pedagogues identify hitherto neglected language elements that merit explicit targeting in second language instruction. The third part consists of contributions that put the pedagogical efficiency of several CL-inspired interventions to the test in classroom experiments. Additions to the currently available armoury of teaching methods are proposed. The kinds of target language items under examination in the book range from single words over multiword units to grammar patterns. Throughout, the volume illustrates how much pedagogy-oriented Cognitive Linguistics has matured in recent years. (http://www.degruyter.com/view/product/62842)
Applications of passive microwave observations of surface soil moisture

In large scale field experiments over the past 10 years, long wavelength microwave radiometers have been used to map surface soil moisture with considerable success. These experiments, which include PIPE (87 & 89), Monsoon 90, Washita 92 and 94, and HAPEX-Sahel, covered a wide range of climatic regimes. The results from all of them have shown that the microwave emission at the 21-cm wavelength is a strong function of surface (0 to 5-cm) soil moisture. The salient results from these experiments are presented and compared. The use of the surface soil moisture data to determine geophysical parameters such as evaporative fraction, soil evaporation and soil hydraulic properties are discussed.
Information policies and government guidance in Nigeria: what hope for rural communities?

The current development crisis in Nigeria is not the result of inadequate resources but is a product of "mismanagement. " Nigeria's lack of an information policy has led to a chaotic information environment. Four development plans from 1962-1985 have dealt with various facets of information policy but did not develop clearly stated and coherent policies. National information policies in Nigeria should focus on identifying information needs, information resource development, coordination and resource sharing, training and education for the information work force, the role of professional associations, promoting effective use, and rural development planning. Since the rural populace constitutes the largest segment of the country's population, providing information to rural areas is of special importance.
Storage rebuild for automatic failure recovery in video-on-demand servers

In a previous study, Wong and Lee (see ICC'97, Montreal, Canada, 1997) proposed a redundant array of inexpensive servers (RAIS) architecture for designing scalable and fault-tolerant video-on-demand systems. Video data are striped across an array of autonomous servers, resulting in a scalable architecture where more concurrent video sessions can be supported by simply adding more servers. Moreover, by adding data redundancy among the servers, client recovery algorithms can be implemented to sustain server failure and provide non-stop video services. We consider the failure recovery issue in RAIS. Specifically, we propose and analyze three algorithms for rebuilding data at a failed server to a spare server in order to restore the system back to normal operation. We derive the performance model and use numerical results to show that automatic rebuild can be done in reasonable time using the proposed rebuild algorithms.
THE SEARCH FOR THE IDEAL

The search for the ideal is a continuing element in human history. Without ideals, few advances would be made. However, unwillingness to accept anything but the ideal constitutes in its extreme form a neurosis, perhaps totally incapacitating the person who suffers from it. Librarianship has been, and is, afflicted with a version of this disease. The central feature is the inability to reduce standards, however arbitrary the standards and whatever the current circumstances. The library system is designed around these standards, which are inviolable, the fixed elements in an otherwise adaptable system. How this operates can best be shown by examples.
Object-oriented approach to PLC software design for a manufacture machinery using IEC 61131-3 norm languages

Presents an application of object-oriented methodology to the development of programmable logic controller (PLC) programs. The PLC is widely used as a computer controller of manufacturing machinery, principally because of its robustness and programming simplicity. The IEC 61131-3 norm has been introduced aiming to provide standard languages and structure to the development environments of PLC programs, that up to now have been strictly bound to proprietary languages. Following the IEC 61131-3 prescription, is it also possible to develop well structured, object-oriented control software, which was hardly possible with the former vendor-specific low-level languages. The paper describes an application of the IEC 61131-3 standard to the development of the control software of a medium complexity manufacturing machinery. The software development methodology is reported and comparison regarding development time, software re-usability and application structuring, is then discussed.
The Effectiveness of Programmed Instruction in Teaching English at the Secondary School Level

Abstract One hundred Jordanian boys were arranged in two matched groups to study the effectiveness of programmed instruction in teaching English at the secondary school level compared to regular classroom teaching. Utilising a ‘t’ test and a 2 x 2 analysis of variance the results indicated the superiority of PI compared to regular classroom teaching. All main effects (method and ability) and three interaction effects were significant. Students low in achievement seem to have benefited more from PI than from regular classroom teaching. These results were interpreted on the basis of the inherent qualities of PI such as structuring the learning situation and providing immediate knowledge of results, which are lacking in regular classroom teaching.
