Images in Electronic Performance Support Systems (EPSS): An Eye Tracking Study

Current forms of online help are increasingly making use of images (graphical illustrations or photographs), along with textual instructions to effectively assist users in performing a specific task. Users typically want to accomplish tasks quickly and devote limited attention to help systems. Hence, it is essential that these images facilitate efficient understanding of the task at hand and complement the instructions well. The first goal of the project was to create quick and inexpensive images that work better than or as well as existing graphical illustrations. The second goal was to conduct a usability test with eye tracking to compare guidance of visual attention by three types of images: graphic illustrations, digital photographs and modified digital photographs. During the test, other key measures like success rates and time on task were also measured. Subjective preferences for the three types of images were also evaluated. Results indicated that the modified photographs performed better in guiding the visual attention of users to the relevant areas of the image than the other two image types. Though not statistically significant, the trend showed that task completion times for tasks with the modified photographs were shorter than those with the other image types (i.e., tasks with modified photographs were quicker than those with other image types). Subjective ratings indicated that participants preferred photographs and modified photographs to the existing graphical illustrations.
A Study of a Scheme to Assess and Improve ESB-based SOA Applications from the S/W Architecture Perspective

In both inside and outside of our country, the interest of the new generation S/W architecture, the SOA(Service Oriented Architecture) is whooped up. We expect that the SOA will become general S/W architecture in several years, but the most compaines of S/W Industry still think that the SOA have much risk to adapt as their s/w architecture. In this paper, We performed the senario based verification of the SOA quantitatively and qualitatively, and presented the validity of the S/W architecture view and the method of adoption of the SOA.

Synthesis and Properties of Biodegradable Segmented Poly-ε-caprolactone

Block copolymers have been used to tune the chemical and physical properties of degradable materials for tissue engineering. In this study, a series of urethane linkages containing segmented poly-e-caprolactone (sPCL) with various block lengths and weight ratios were synthesized and characterized. The molecular conformations and characteristics of sPCL were investigated using nuclear magnetic resonance, Fourier transform-infrared spectroscopy, and gel permeation chromatography. The effects of the molar ratio and molecular weight of e-caprolactone precursors on the mechanical properties were studied. The results show that the tensile strength of sPCL, which is tunable, was 35 MPa, much higher than that of a typical PCL sample (16 MPa). In addition, it was found that increasing the number of urethane linkages improves elongation. In vitro studies confirmed that the change of molecular weight of sPCL was significantly accelerated compared to that of homopolymers. These results suggest that sPCL has potential as a tailorable material for implantable devices.
Does The Ilo Definition Capture All Unemployment

The labour market status of many non-working persons is at the boundary between unemployment and inactivity. Like the unemployed, they seek and are available for work; unlike them, their last search action was not recent enough to meet the ILO definition of unemployment. In this paper we examine by non-parametric tests how the transition probabilities of these out-of-the-labour-force job seekers differ from those of the unemployed as well as the other non-participants. First, using data from the European Community Household Panel, we show that in most EU countries these job seekers constitute a distinct labour market state. Second, we rely on information only available in the Italian Labour Force Survey to derive a measure of search intensity which we use to break down the out-of-the-labour-force job seekers. On the basis of their transition probabilities, the most active are indistinguishable from the unemployed.
Vi vs Dom: Idrottens förmåga och problem med integration

Ivar-Lo Johansson tvivlade pa idrotten redan pa 1930-talet. Om man lyssnar till debatter om vad idrotten ska utratta och vad idrotten har for roll i dagens samhalle sa tycks det vara fa som likt Ivar-Lo tvivlar. Han tyckte om idrott, men forsokte samtidigt se de problem och motsattningar som finns inom och runt idrotten. Darfor sympatiserar jag med hans hallning: idrott blir mer intressant om man bade ser dess positiva och negativa sidor. En av dagens debatter kring idrott handlar om rollen som integrationsarena. Ar idrotten bra for integration mellan olika etniska grupper i dagens Sverige? Svaret ar givetvis varken entydigt ja eller nej. Jag kommer i det foljande att diskutera vad som kan ses som positivt och negativt nar det galler idrott och integration. Grunden for mitt resonemang ar framst den egna forskningen fran ett antal projekt, men aven forskning och debatt fran andra delar av Sverige samt internationellt. Mina egna projekt har till stor del fokuserat hur unga migranter, framst unga man, tanker kring och praktiserar idrott och hur dessa erfarenheter moter idrottens institutioner pa olika nivaer. Jag kommer inte att borja med att tvivla. Idrottens sjalvbild nar det galler integration ar min utgangspunkt. Vilka aspekter ar det man pekar pa for att havda idrottens mojligheter och fordelar? Jag tror det ar pedagogiskt riktigt att borja med de positiva sidorna. Tvivlaren slapper jag fram pa slutet. Hur tanker da idrottsrorelsen om den egna verksamhetens formaga och mojligheter till integration? I Idrotten vill, rorelsens egna ide- och regelverk, proklameras att idrotten ar till for alla oavsett kulturell, social, religios bakgrund och tillhorighet. Man menar till och med att idrotten ar en sarskilt bra arena dar olika manniskor kan motas och utvecklas tillsammans. I liknande dokument for de olika distrikten, till exempel Stockholms idrottsforbund, finns nastan ordagranna formuleringar. Idrotten ar, menar man, ett tillfalle for demokratisk fostran dar alla ar valkomna. I en debattartikel i en av landets storsta tidningar och underskriven av flera ledande forbundsrepresentanter inom idrotten havdas att ”det andra talar om, det gor vi nar det galler integration”. Idrottsrorelsens sjalvbild verkar sa langt stolt och positiv i fragan. Samtidigt pagar projekt sedan flera ar och pa flera hall i landet

DESIGN OF 100 kHz SONAR FOR MARINE MAPPING APPLICATIONS

Side scan sonar (SSS) is an important mapping tool in underwear imaging system. This paper provides sufficient information on SSS design. SSS is known for very high quality, high resolution, ocean bottom imaging. It is able to rapidly survey large ocean areas for bottom and suspended sea-mines or other kinds of threats. Another operational aspect of these systems is that they allow autonomous underwater vehicles (AUVs) to conduct operations, mostly in shallow water and near land. It produces a representation in image form of the seabed; however, no closed form analytic expression or direct modeling technique exists to represent this complex process. In this paper the basic principle is presented for a model for the simulation of SSS, which produces as its output a qualitative image of the form generated by the actual SSS. The model considers the underlying physical processes including the effects of the refractive water medium, the scattering from the seabed and the transducer motion and directivity characteristics. Further, this work concerns the design and analysis of SSS via MATLAB simulation in order to satisfy the operational requirements. Moreover, this research has tried to indicate the various problems that may arise when a SSS operates in its near-field region and suggests certain solutions. The active sonar equation and its factors were explained and were evaluated.
Route Lifetime based Interactive Routing in Intervehicle Mobile Ad Hoc Networks

The main goal of this paper is to better understand the route lifetime dynamics in Intervehicle communication networks (IVC) or what we call intervehicle mobile ad hoc networks (iv-MANETs) that are a special class of MANETs but exhibit very different behavior from them. We consider the problem of finding an optimal multi-hop route between two vehicular nodes in an iv-MANET. For a given choice of the number of hops and distances between intermediate nodes, we seek the characterizing properties of choice of speeds of the intermediate nodes so as to maximize the expected lifetime of the multi-hop route. Our analytical model inherently incorporates the randomly changing speeds of nodes over time and hence the optimal choice depends on the dynamics of the stochastic process corresponding to the speed of the nodes. We suppose that for establishing a route the locations and speeds of other vehicles are known. Under a markovian assumption on the process of the speed of nodes, we show that the optimal choice of speeds attempts to equalize the lifetimes of adjacent links in a route. A monotone variation property of the speed of the intermediate nodes under the optimal policy is proved. These solution structures have been confirmed with an extensive simulation study. The heuristics and structures developed in this paper can serve in designing a new set of efficient interactive routing protocols specifically tailored for high mobility ad hoc networks and iv-MANETs in particular.
Effect of 22(S), 23(S)-Homobrassinolide on Adventitious Root Formation in Grape Rootstocks

In recent times, brassinosteroids have been identified as a group of hormones that regulate plant growth and development. They affect plant development from seed germination to senescence. The aim of this research was to study the effects of brassinosteroids on the rooting of three American grapevine rootstocks (1103 Paulsen, 110 Richter and 99 Richter) used frequently to produce grafted grapevines. Rootstock cuttings were dipped for 10 minutes into five different concentrations of 22(S), 23(S)-homobrassinolide and planted into a peat-perlite mixture. Data such as fresh and dry root weight, root number and development level were collected and assessed. Some shoot growth features were also determined. The results showed that the grapevine rootstocks with the most significant response in improved root and shoot growth were 1103 Paulsen, followed by 110 Richter. Root development level was influenced by both the rootstock and the concentrations of the substance. The lowest concentration, 0.05 ppm, induced more root numbers in 1103 Paulsen, while 0.15 ppm resulted in the highest number of roots in 99 Richter. A statistical analysis of the data revealed a significant difference between root development and shoot growth.
3-D Stress Wave Code for the ILLIAC 4

Abstract : A novel finite element scheme has been developed for simulating stress waves using 1-D, 2-D, and 3-D orthogonal curvilinear coordinate systems. Finite deformations and nonlinear material behavior are accommodated using a Lagrangian formulation. In addition, the explicit time stepping scheme is efficient; computing rates of 0.4 and 1.2 m-sec per element per numerical time step have been achieved in 2-D and 3-D test calculations on the ILLIAC IV. About 50 percent slower computing rates were obtained in test calculations performed in 2-D and 3-D spherical coordinate systems.
A coupled finite mixture model for transcriptional module discovery

Approaches to elucidate complex gene regulatory networks usually rely on the analysis of transcriptional modules (TMs). Two high-throughput technologies, gene expression microarray and Chromatin Immuno-Precipitation on Chip, often provide complementary information for discovering TMs. To efficiently integrate these two data sources, we propose a novel Bayesian model referred to as Coupled Finite Mixture Model (CFMM), which permits a separate clustering for each data source and also explicitly models their dependence. We validate our model in both a synthetic dataset and a real dataset. Our method is shown to find more consensus genes and the resulting TMs have improved biological functional coherence than those inferred by other state-of-the-art methods.

BLIND SOURCE SEPARATION FOR CONVOLUTIVE MIXTURES BASED ON COMPLEXITY MINIMIZATION S

Using algorithmic complexity to perform blind source separation (BSS) was first proposed by Pajunen. This approach presents the advantage of taking the whole signal structure into account to achieve separation, whereas standard ICA-based methods only use either time-correlations or higher order statistics in order to do so. Another advantage of this approach is that no assumptions about the probability distribution of the source signals need to be made. However, although algorithmic complexity based methods have been shown to outperform standard ICA algorithms in the instantaneous BSS case, they haven’t been applied to convolutive BSS to the present date. In this paper, we show that it is also possible to use algorithmic complexity as a separating criterion to perform BSS for convolutive mixtures and suggest a method to do so. Testing the proposed method by computer simulation yielded results which are encouraging in terms of SNR performance.
I/O-Efficient Algorithms and Data Structures

In many modern applications that deal with massive data sets, communication be-tween internal and external memory, and not actual computation time, is the bottleneck in the computation. This is due to the huge diﬀerence in access time of fast internal memory and slower external memory such as disks. In order to amortize this time over a large amount of data, disks typically read or write large blocks of contiguous data at once. This means that it is important to design algorithms with a high degree of locality in their disk access pattern, that is, algorithms where data accessed close in time is also stored close on disk. Such algorithms take advantage of block transfers by amortizing the large access time over a large number of accesses. In the area of I/O-eﬃcient algorithms the main goal is to develop algorithms that minimize the number of block transfers (I/Os) used to solve a given problem. These lectures will cover I/O-eﬃcient algorithms and data structures for a few fundamental problems in computational geometry and graph theory, with focus on the techniques used to design such algorithms. The problems include sorting and fundamental searching problems, as well as the list ranking graph problem. Most of the covered material is described in [1, 2, 3].
A Comparison of Instructor Time and Effort between Traditional and Online Classrooms.

This research study compares the time and effort involved in preparing and managing traditional versus online classrooms. A survey was used to collect data from professors with experience in teaching both formats. Previous studies showed that instructors spent more time and effort managing online versus traditional classrooms. Time and effort for this study were divided into seven hypotheses: instructor preparation for online courses will require more time and effort than instructor preparation for traditional courses; student-instructor interaction for online courses will require more time and effort than student-instructor interaction for traditional courses; course material maintenance for online courses will require more time and effort than course material maintenance for traditional courses; instructional time for online courses will require more time and effort than instructional time for traditional courses; assessment for online courses will require more time and effort than assessment for traditional courses; more time and effort will be spent on technical issues for online courses than for traditional courses; and graduate assistant aid for online courses will require more time and effort than graduate assistant aid for traditional courses. Results indicated no statistical significance of any of the hypotheses. (Contains 10 references.) (Author/SM) Reproductions supplied by EDRS are the best that can be made from the original document.

The Use of Seven Simulation Activities in a College Economics Survey Course.

The simulation-gaming approach to college introductory economics courses benefits students who possess a certain Combination of cognitive learning styles. The Cognitive Style Questionnaire, administered to 120 freshmen, identified those students who obtain meaning from spoken words, numerals, or mathematical symbols; have the ability to place themselves in another's position; and are influenced by peers as those who would benefit from the simulati.on-gaming method. Students who obtain meaning from written words, numerals, or mathematical symbols, direct their own behavior, and make their own decisions were identified as learning best from the lecture-discussion approach. Students were then randomly assigned to courses using one of the two approaches. The experimental class integrated simulation with the lecture method; the control class used the letture method exclusively. Experimental classes used role playing, team membeiship, and a computer simulation to demonstrate microeconomic and macroeconomic concepts. Students responsive to simulation techniques in the experimental classes received higher grades than their counterparts in the control classes; conversely, students responsive to lecture-discussion methods recorded higher grades in the control classes than their counterparts in the experimental classes.

A Framework for Retargeting Radio Designs

Abstract : We address the process of designing software defined radios. Our goal is to design radio functions once and use automated tools to transform the design to implementations on different platforms. ReTarget is an approach and a process that (1) describes radio functions in a specification language, Rosetta, (2) translates specifications to an intermediate language suitable for hardware and software implementation, and (3) translates the intermediate language to VHDL and C programs. In this feasibility study, we demonstrated specifying radio functions in a high level language, translation to an intermediate language, and further translation to an implementation language. A number of issues arose during the study. Specifically, (1) what mechanisms, that are compatible with both hardware and software implementation, should be used to exchange information between radio functions and (2) how to set up control and management of radio function in this primarily data-flow oriented domain.
Conceptual Combination and Scientific Discovery

The question of how concepts are formed was central for positivist and operationalist philosophers concerned to root scientific thought directly in experience. Although the positivist program has been abandoned, the current interest in the philosophy of scientific discovery shows the need for a theory of conceptual development. This paper offers a theory of how new concepts can arise, not by abstraction from experience or by definition, but by conceptual combination. Such combination produces a new concept as a non-linear, non-definitional amalgam of existing concepts. After proposing rules intended to account for a variety of mundane cases of conceptual combination, the paper presents several illustrations of how scientific concepts have arisen through combination.
