An Approach Based on Data Mining to Support Management in E-Commerce

The ability of managers to analyze large volumes of data is not enough to identify all relevant associations and necessary for the decision-making process. Make use of a classification model can generate information that typically a manager could not create without the utilization of this technology. The aim of this work is to reach a classification model, based on data from purchases made by customers through electronic media in an automated manner. Precisely this model presents a set of rules to assist in decision-making applicable to a sale of vehicles, parts and accessories. For the construction of this model, we applied a process of knowledge discovery in databases, in which classification techniques was evaluated in an experiment regarding accuracy, interpretability and learned model to the computing performance. Data mining has been used to find this classifier.
Gastro-retentive oral drug delivery systems: a promising approach for narrow absorption window drugs

Drugs with narrow absorption window (NAW) are those drugs that are absorbed from a specific region (most notably first part) of the gastrointestinal tract. Therefore, typical modified/sustained release formulations of those drugs cannot provide a true long-acting drug release. Once the dosage form has passed the absorption sites at the specific regions of the small intestine; the drug is no longer absorbed from the modified release dosage form and the bioavailability is adversely decreased. While there are many pharmacological classes such as centrally acting skeletal muscle relaxants, anti-parkinsonism drugs and anti-infective belong to NAW drugs and are required to be formulated in modified release dosage forms. Modified release dosage forms based on gastroretentive technologies could hold a promise. Such dosage forms aim to release drugs in the upper part of the gastrointestinal tract especially in the stomach in a controlled release manner that might provide sustained release characteristics without sacrificing much of total bioavailability. This review provides critical appraisal on different technologies, polymers, candidate drugs for gastroretentive technologies.
On a Triptych of Software Development

We shall present core aspects of the Triptych approach to software engineering. The benefits from deploying this approach are that we both achieve the right software and software that is right [27, Boehm 1981]. The right software is software that meets all of the customers’ expectations and only those. Software that is right is software that is correct with respect to specific requirements prescriptions. Experience has shown that using also the formal techniques 3 part of the Triptych approach has lead to projects that are on time and at initially estimated costs [83]. To achieve the right software we “prefix” the phase of requirements engineering with a phase of domain engineering – and these lecture notes will present core aspects of domain engineering. To achieve software that is right we do two things: (i) “derive” requirements prescriptions from domain descriptions and software design from requirements prescriptions – and this these lecture notes will present core aspects of a somewhat different approach to requirements engineering, and (ii) formulate descriptions and prescriptions both informally, in precise, say English narratives, and formally. The latter is not shown in these lecture notes. The “somewhat” different approach to requirements engineering, however, and as 4 we shall see, fits reasonably “smoothly” with current requirements engineering approaches, [62, Axel van Lamsweerde]. Precursors of the ‘triptych’ approach was used in DDC’s 44 man-year Ada Compiler development project [25]. That project was on time and at cost, and time and cost were significantly below those of other commercial Ada compiler developments [32]. The ‘triptych’ approach has been in partial 5 use since the early 1990s, including at the United Nations University’s International Institute for Software Technology (www.iist.unu.edu). Young software engineers, while being tutored by UNU-IIST’s science & engineering staff, domain engineered, requirements engineered and software designed (incl. implemented)[2] trustworthy
A Full Homomorphic Message Authenticator with Improved Efficiency

In the system of a fully homomorphic message authenticator, anyone can make any computations based on authenticated data. At the same time, a short tag is produced to authenticate the result of the computation. Without the underlying data, the user can use his private key to verify this tag for ensuring that the claimed result is correct. Recent, Gennaro and Wichs use a fully homomorphic encryption to construct a fully homomorphic message authenticator. In this paper, we propose a fully homomorphic message authenticator with improve efficiency than Gennaro and Wichs's construction. Our fully homomorphic message authenticator is of less verification complexity than Gennaro and Wichs's construction.
A General Framework of Augmented Reality Aided Teleoperation Guidance

Augmented Reality (AR) has been demonstrated to be an efficient way to overcome the negative effect of time delays in teleoperation, because AR can superimpose the virtual simulation results on real working conditions in real-time. This paper proposes a general framework of Augmented Reality Aided Teleoperation Guidance (ARATG), which can support not only 3D predictive information but also operation guidance. Our general framework employs three individual but cooperative modules called tracking, image acquisition and interaction. Tracking module estimates the pose of virtual objects. Image acquisition module decides the type and content of virtual objects. And interaction module manages the multiform interactive information. A prototype system is implemented based on this ARATG framework, the experimental results show that our framework is both powerful and easy-to-use.
Learning models of camera control for imitation in football matches

In this paper, we present ongoing work towards a system capable of learning from and imitating the movement of a trained cameraman and his director covering a football match. Useful fea- tures such as the pitch and the movement of players in the scene are detected using various computer vision techniques. In simulation, a robotic camera trains its own internal model for how it can affect these features. The movement of a real cameraman in an actual foot- ball game can be imitated by using this internal model.

Loeys–Dietz syndrome in pregnancy

Loeys–Dietz syndrome is a recently described condition which causes cardiovascular, craniofacial, neurocognitive and skeletal abnormalities due to mutations in components of the transforming growth factor-β signalling pathway. Associated vascular abnormalities include vessel tortuosity and an increased incidence of vascular dissection. Pregnancy increases the risk of aortic dissection compared to non-pregnant individuals and an underlying condition such as Loeys–Dietz syndrome increases this further. While aortic dissection is well described in pregnancy in Loeys–Dietz syndrome, some women can have uncomplicated deliveries, particularly when the risks of the condition are actively managed. Such pregnancies should be considered high-risk, and women should be counselled and managed accordingly. Here we describe two pregnancies in one woman, both with successful outcomes, followed by a summary of the key management principles.
The Gastroesophageal Reflux Disease Questionnaire in Adolescents: What Is the Best Cutoff Score?

Background A self-assessment questionnaire, the GERD-Questionnaire (GERD-Q) was used to determine the prevalence of GERD in adolescents, describe the related factors, and determine the impact on quality of life (QoL). Methods The incidence of GERD was evaluated using the GERD-Q in adolescents aged 12–18 years. The Pediatric Gastroesophageal Reflux Disease Symptom Questionnaire and Quality of Life Questionnaire (PGSQ-A) for adolescents were additionally administered. Some factors considered related to GERD were also evaluated. Results The 520 adolescents were included. The prevalence of suspected GERD, according to a GERD-Q cutoff score of ≥7 was 32.9%, and those drinking soda were 1.7 times more likely to have GERD (95% confidence interval, 1.3–2.2; p<0.001). However, soda consumption was not a risk factor for development of GERD symptoms. Applying a cutoff score of ≥8, only 10.9% of the participants had a positive GERD score, but the association with soda consumption persisted. The median PGSQ-A score in subjects suspected of GERD was 8 (range 0–37) on weekends and 1 (range 0–17) during weekdays (p<0.001) compared to those not suspected of GERD, with a median of 2 (range 0–27) during weekends and 0 (range 0–10) during weekdays. Heartburn, regurgitation, and extraesophageal symptoms correlated significantly with QoL (p<0.001). Conclusion The prevalence of suspected GERD in adolescents was 32.9% or 10.9%, depending on the cutoff score used. There was a statistically significant difference in PGSQ-A scores between the subjects suspected or not of GERD, indicating an impaired QoL.
File System Support for Low-Bandwidth Thumbnails

Users are frustrated by the current experience of browsing, downloading, and exchanging files in low-bandwidth networks, such as ad hoc wireless networks. One improvement to this experience is to let users first locally interact with file thumbnails — graphical summaries of file contents — and fetch complete files only if necessary. These thumbnails can be sent quickly over the network and augment traditional metadata, such as file names and ownership. To reduce bandwidth consumption, thumbnails must be generated remotely. In prior work, server-side application programs generate thumbnails in response to users’ requests. In contrast, we propose extending underlying file system functionality to support direct generation and storage of thumbnails. Through inode changes or, more simply, through extended file attributes, we envision embedding thumbnails within the file system itself, just as human-readable names and ownership are today. Making thumbnails a first-class object directly linked to their uncompressed counterpart ensures consistency through modify-onwrite regeneration and guarantees equal thumbnail and file data access control. Through directly embedding thumbnails within the file system, we can provide assurances and efficiencies beyond what is possible with application-level techniques.
Effects of Equal Volume High-Repetition Resistance Training With Different Workout Frequency on Muscle Mass and Muscle Performance in Postmenopausal Women

The purpose was to examine the effects of equal volume, high-repetition resistance training (HRRT) to volitional fatigue, with different workout frequency, on muscle mass and muscle performance in healthy postmenopausal women. After matching participants for age, weight and years post-menopause, postmenopausal women were randomized to perform HRRT two days per week (HRRT-2; 60.8 ± 5.5 years, 72.1 ± 16.4 kg, 160.2 ± 3.9 cm; 3 sets of 20-30 repetitions/set to volitional fatigue for elbow and knee flexion and extension) or three days per week (HRRT-3; 61.8 ± 4.6 years, 67.6 ± 13.6 kg, 160.7 ± 4.4 cm; 2 sets of 20-30 repetitions/set to volitional fatigue per exercise) for 8 weeks. Prior and following training, assessments were made for muscle thickness of the elbow and knee flexors and extensors (B-mode ultrasound), muscle strength (1-repetition maximum for elbow and knee flexion and extension), and muscle endurance (maximum number of repetitions performed at 50% baseline 1-repetition maximum for elbow and knee flexion and extension). There was a significant increase over time for all measures of muscle thickness, muscle strength, and muscle endurance (p < 0.001), with no differences between groups. Equal volume, HRRT (independent of training frequency), is an effective intervention for improving muscle mass and muscle performance in postmenopausal women.
Glass, Paper, Scissors: Investigating the Metaphors of the Glass Cast through Paper Prototyping

This article reflects on the importance of user feedback in early stages of the design process of Glass Cast. A 3-D interface, Glass Cast is intended for the visualization of knowledge networks, including parameters such as authorship, time, subject, discipline, and connections between documents in a corpus. The name Glass Cast refers to the working metaphor of the prototype, which is a cast sculpture in which the object of representation appears as negative space in a glass block. The participants in this study, graduate students and faculty in the humanities and social sciences, provided feedback on a low-fidelity paper prototype in the context of interviews. Their feedback is organized following the taxonomy of user-interface metaphors.

A Low Profile Wideband Log Periodic Microstrip Antenna Design for C-Band Applications

In this study, a wideband low profile microstrip antenna design for C-band applications is presented. The proposed antenna consists of a monopol log periodic patch in the equilateral triangular dimensions with the microstrip line fed and a rectangular ground plane. The antenna has 9×19.8 mm2 overall size, thickness of 1.6 mm and 4.3 dielectric constant. According to the simulation results, the proposed antenna has a very wide bandwidth while operating in the frequency band of 4.25-7.95 GHz and 5 GHz resonance frequency. The proposed antenna was also prototyped on FR4 substrate with the 0.02 tangent loss and the measurement results were quite similar by the simulated results.
Anytime, anywhere: the social impact of emerging communication technology

The article discusses the advent of anytime, anywhere communication capability and its potential impact on our society. It examines the ways in which technology becomes accepted and integrated into our lives, including the role of human values. The report also focuses on both the beneficial and detrimental effects of emerging communication technology, such as its ability to put the disabled and disenfranchised on equal footing with the rest of the online population, and the possibility that individuals will become so isolated behind their computer screens that they will lose the ability to carry on face to face relationships. Finally, privacy and data security are discussed, as well as the limitations of physiology in a 24 hour society.
Intelligent parking reservation service on the Internet

The described intelligent parking service is a part of an ITS (intelligent transportation system) in which parking facilities are conceived of in terms of various new functions which they can provide. This service does not simply manage the internal operations of a parking facility; rather, it is designed to be compatible with a wide range of aspects that are intertwined with parking facilities. One of the features of the system developed by NTT is a parking reservation service that allows drivers to reserve a parking spot through the Internet when a parking space is available. The system enables motorists to find available parking spaces at their destinations easily and quickly by using the Internet. When used together with a smart card, the system can provide the motorists with recognition and payment services. This paper depicts the service concept of intelligent parking reservation systems and overviews the prototype developed by NTT.
Effects of a Cardiac Rehabilitation Program Versus Usual Care on Cardiopulmonary Function in Patients With Cardiac Syndrome X

The findings showed that adding a 4-wk course of cardiac rehabilitation to usual care for patients with cardiac syndrome X not only increased the Duke Treadmill Score and exercise test duration but also improved the resting oxygen (O2) pulse, the peak O2 uptake, and the first-minute recovery heart rate. Purpose: Because of uncertainty in the pathophysiological process, the treatment of cardiac syndrome X (CSX) is still under study. Addressing the effects of cardiac rehabilitation (CR) can help promote the prescription of this modality as an adjuvant therapy for these patients. Methods: This study was performed on 30 patients with effort-induced angina pectoris using a positive exercise test and/or myocardial perfusion scan in the absence of obvious stenosis or a stenosis of <50% on coronary angiography. The patients were divided into the CR and usual care (UC) groups and underwent cardiopulmonary exercise testing with gas exchange analysis before and after the study. The Duke Treadmill Score was used to compare prognosis and survival estimates of patients. Results: An increase in peak oxygen uptake (o2) was significantly higher in the CR group than in the control group (P = .017). Resting o2 was also increased in the CR group, but its difference with the UC group was not statistically significant. Resting O2 pulse was increased in the CR group, which significantly differed between groups (P = .041). Exercise test duration and the Duke Treadmill Score significantly increased in the CR group as compared with the UC group (P = .003 and P = .002, respectively). Also, recovery heart rate in the first minute was significantly improved in CR group. Conclusion: Adding a 4-wk course of CR to UC for patients with CSX not only increased the Duke Treadmill Score and exercise test duration but also improved the resting O2 pulse, peak o2, and first-minute recovery heart rate.
Using a Word Processor to Tag and Retrieve Blocks of Text

Sophisticated text management software is currently available for doing thematic or code-based analysis, the principal procedural approach to qualitative data analysis. Such packages allow researchers to tag and retrieve contiguous blocks of data, maintain complex codebooks, manage large corpora of data, and display search results in interesting ways. For simple projects, however, with a few themes and a small number of texts, a complex program that requires a large investment of time to learn may be more technology than one needs. This article provides tips for making better use of the humble word processor, in this case, Microsoft Word. The use of text-formatting features, find-and-replace command, and Microsoft Word’s macro programming language can be used to mark themes in texts and retrieve exemplars of themes on demand.
Classification with Imbalanced Data

problems in which the number of instances of a particular class is much lower/higher than the instances of the other classes, one commonly adopted strategy is to train the classifier over a small, balanced portion of the training data set. Although straightforward, this procedure may discard instances that could be important for the better discrimination of the classes, affecting the performance of the resulting classifier. To address this problem more properly, in this paper we present MOGASamp (after Multiobjective Genetic Sampling) as an adaptive approach that evolves a set of samples of the training data set to induce classifiers with optimized predictive performance. More specifically, MOGASamp evolves balanced portions of the data set as individuals of a multi objective genetic algorithm aiming at achieving a set of induced classifiers with high levels of diversity and accuracy. Through experiments involving eight binary classification problems with varying levels of class imbalancement, the performance of MOGASamp is compared against the performance of six traditional methods. The overall results show that the proposed method have achieved a noticeable performance in terms of accuracy measures.
Ant Colony Scheduling for Network On Chip

It is undeniable that scheduling plays an important role in increasing the network quality on chip.If experts realize the significant of mapping and scheduling in getting rid of delays and increasing performance of these systems, they will ponder over these activities much more scrupulously. The operation scheduling problem in network on chip (NoC) is NPhard; therefore, effective heuristic methods are needed to provide modal solutions. In this paper, ant colony scheduling was introduced as a simple and effective method to increase allocator matching efficiency and hence network performance, particularly suited to networks with complex topology and asymmetric traffic patterns. The proposed algorithm was studied in torus and flattened-butterfly topologies with multiple types of traffic pattern. For evaluating the performance of the proposed algorithm, specialized simulator network on chip entitled by BookSim working under Linux operation system was used. Evaluation results showed that this algorithm, in many causes, had positive effects on reducing network delays and increasing chip performance compared with other algorithms. For instance, for a complex topologies, this algorithm under maximum injection_rate of up to (10%) increasing throughput have been observed, injection rate, on average, compared to other existing algorithms.
Species diversity of Hyalinobatrachium glassfrogs (Amphibia: Centrolenidae) from the Guiana Shield, with the description of two new species

Basic information about the taxonomy, biology and distribution of Hyalinobatrachium glassfrogs of the Guiana Shield (GS) is scarce, ambiguous, and in many cases even contradictory. In this review we aim to clarify the current taxonomic status of this group by means of phenotypic (morphology, morphometrics and bioacoustics) and molecular (mitochondrial DNA sequences) comparisons. Eight species have previously been recognized for the GS: H. crurifasciatum, H. eccentricum, H. fleischmanni (initially described as Hylella cappellei in the GS), H. iaspidiense (with the putative synonym H. nouraguense), H. ignioculus, H. mesai, H. mondolfii, and H. taylori. Our data support the resurrection of H . cappellei from its synonymy with H. fleischmanni. Hyalinobatrachium crurifasciatum, H. eccentricum, and H. ignioculus are proposed as junior synonyms of H. cappellei. We show that none of the four paratypes of H. taylori belong to this species and we assign two to H. cappellei and two to H. mondolfii. Additional specimens previously identified as H. taylori are reassigned to H. cappellei, and hence H. taylori is redefined. Hyalinobatrachium nouraguense is confirmed as a junior syn
