Decision-Tree Models for Predicting Time Performance in Software-Intensive Projects

Initial requirements, new requirements and technical issues are the main factors that have a great effect over the software product development process. Difficulties resulting from incomprehensibility of initial requirements indicate two sub-factors: Deviations determined during analysis of initial requirements and deviations resulting from interpretation of requirements inaccurate and incomplete. New requirements being received from customers or end users during the development process affect the project performance. There can be problems during the implementation of product specifications, inaccurate formation of architectural design and technical solutions, incorrect coding of functions, or wrong realization of interfaces. The general technical problems cover the all problems arising from technical reasons and the negative situations they create on the project. During the design and implementation activities of software intensive projects, these tree main factors can be affected by other sub-factors. The aim of this study is to examine the factor classes which influence these three problem domains with CHAID Chi-squared Automatic Interaction Detection technique. Time deviations caused by initial requirements, new requirements and general technical problems are selected as target variables. In this research, 75 projects that develop software intensive products are studied to formalize the most accurate decision mechanism.
Simulation of Atmosphere in Trowulan during the Golden Era of Majapahit Using Virtual Reality

Over time the kingdom of Majapahit is one of the historical heritage sites that began to disintegrate over time. That conditions because people are not interested to see the historic relic site located in East Java, Indonesia. But with the development of technology, especially virtual reality, it is possible to visualize almost everything. In this research, we use virtual reality as an interactive and interesting information media to create environment along with atmosphere in Majapahit kingdom glory era especially in Trowulan. By using this system, we are expected could attract public interest to learn more about the history of Majapahit. The created system includes the process of making a virtual world such as settlement, virtual humans which is includes fishermen, farmers, adult men, adult women, children, warriors, and virtual animals like chickens, dogs, and also there is a player that can be controlled by user. The virtual humans and virtual animals will have finite state machine design to regulate the behavior and habits. This system is made using Google cardboard software development kit and Unity and will run on android devices.
Collocated mobile collaboration

Mobile devices have changed, and continue to shape, the world in which we live. When these devices were first introduced they were most often used in isolation to schedule appointments, take notes, play games, or view or edit pictures and stories. The extent of the collaboration on these mobile devices was to make phone calls, which has led to their worldwide distribution. Despite their broad proliferation, there are limitations such as small screen size and limited interaction space. We believe that by bringing devices and people together, these limitations can be overcome. In this video submission, we illustrate the potential of devices and people working together by showing how children can collaboratively read and create stories using mobile devices and exploit the shoulder-to-shoulder collaborative situation to share and expand the interactive space.
Efficient Anonym Smart Card Based Authentication Scheme for Multi-Server Architecture

Multi-server authentication schemes are very practical from a user point of view, since they allow a user to get access to different services on different servers with one single registration. Smart card based approaches lead to more secure systems because they offer two-factor authentication, based on the strict combination of user's password and the possession of the smart card. In this paper, we first show that a previously proposed scheme does not satisfy perfect forward secrecy and is not resistant against insider attacks. Next, we propose a very efficient smart card based authentication scheme, solely using xor and hash operations, which is resistant against dishonest users and servers. Also anonymity and untraceability of user's behaviour is avoided.
Control of dynamic stability during gait termination on a slippery surface in Parkinson's disease

This study investigated how Parkinson's disease (PD) affects the ability to switch from locomotion to gait termination (GT) during planned and cued GT and examined the effect of PD on the integration of a reactive, balance maintenance strategy into voluntary GT. After a series of stops on a stable surface, eight participants with and 10 without PD stopped on a surface, which slid quickly and unexpectedly forward mimicking a slippery surface. PD caused instability during the completely voluntary nonslippery stops (P = 0.012) but not during the slippery stops, which required a reactive movement. The PD group walked slower [0.9–1.0 m/s vs. 1.3 m/s, respectively (P < 0.001)] with shorter steps during the first step of nonslippery GT (P = 0.016) and with wider steps during all steps of nonslippery GT (P ≤ 0.05). Similar to controls, the PD group increased lateral stability during planned GT compared to cued GT (P = 0.007). The timing of gait termination was similar between groups in all conditions. During the unexpected perturbation, both groups used a generalized slip response to regain balance after the perturbation. PD did not affect the ability to stop walking or to integrate a balance‐correcting response into GT but did affect movement speed, size, and stability of the voluntary movement. © 2008 Movement Disorder Society
Impact of mass media over public opinion: about the dangers and prejudices of being adolescents?

Resumen Este trabajo busco reflexionaren torno al trata-miento noticioso que se le brinda, a los episodios de infraccion de ley cometidos por adolescentes en Valdivia. Por consiguiente, se procedio al analisis del discurso (Van Dijk, 1990), desde una logica interpre-tativa con enfasis en la macroestructura semantica con que se construye y describe la noticia. Dicho analisis nos posibilito observar que las noticias en que aparecen vinculados jovenes, expresan un dis-curso sensacionalista y estigmatizador, que fomenta y perpetua la reproduccion de estereotipos asocia-dos a la adolescencia, caracterizada por la agresi-vidad y la violencia, la transgresion permanente de las normas y el uso de armas para intimidar a otros, como factores explicativos de la conducta delictual. Finalmente, el trabajo reflejael impacto que pro-vocan los medios de comunicacion, sobre la opinion publica, fragmentando al sujeto producto de los pre-juicios construidos en torno a la adolescencia.

Genetic recombination and the cell cycle: what we have learned from chromosome dimers

Genetic recombination is central to DNA metabolism. It promotes sequence diversity and maintains genome integrity in all organisms. However, it can have perverse effects and profoundly influence the cell cycle. In bacteria harbouring circular chromosomes, recombination frequently has an unwanted outcome, the formation of chromosome dimers. Dimers form by homologous recombination between sister chromosomes and are eventually resolved by the action of two site‐specific recombinases, XerC and XerD, at their target site, dif, located in the replication terminus of the chromosome. Studies of the Xer system and of the modalities of dimer formation and resolution have yielded important knowledge on how both homologous and site‐specific recombination are controlled and integrated in the cell cycle. Here, we briefly review these advances and highlight the important questions they raise.
Antimicrobial Activity of Blended Essential Oil Preparation

Antimicrobial activities of two blended essential oil preparations comprising lavender oil, petigrain oil, clary sage oil, ylang ylang oil and jasmine oil were evaluated against various pathogenic microorganisms. Both preparations showed antimicrobial activity in the agar disc diffusion assay against the Gram-positive bacteria, Staphylococcus aureus ATCC6538 and S. epidermidis isolated strain, the fungus, Candida albicans ATCC10231, and the Gram-negative bacterium, Escherichia coli ATCC25922, but showed no activity against Pseudomonas aeruginosa ATCC9027. The minimum inhibitory concentration (MIC) of these preparations was evaluated. By the broth microdilution assay, preparation 1, comprising lavender oil, clary sage oil, and ylang ylang oil (volume ratio 3:4:3), exhibited stronger antimicrobial activity than preparation 2, which was composed of petigrain oil, clary sage oil, and jasmine oil (volume ratio 3:4:3). Moreover, the sum of the fractional inhibitory concentrations (Σfic) of preparation 1 expressed a synergistic antimicrobial effect against the tested microorganisms (Σfic<1). The blended essential oil preparations, characterized for their components by GC/MS, contained linalyl acetate, and linalool as major components. Our experiments showed that the differential antimicrobial effect of either blended oil preparations or single/pure essential oils may be influenced by the amount of linalool and linalyl acetate, and the number of active components in either the blended preparations or single/pure essential oils. In addition, blended oil preparations expressed synergistic antimicrobial effect by the accumulation of active components such as linalool and linalyl acetate and combining active constituents of more than one oil.
Florida's Weakened Motorcycle Helmet Law: Effects on Death Rates in Motorcycle Crashes

Objectives: Effective July 1, 2000, Florida's universal helmet law was amended to exclude riders ages 21 and older with insurance coverage providing at least $10,000 in medical benefits for injuries sustained in a motorcycle crash. Observed helmet use in Florida was reported to have declined from nearly 100% in 1998, before the law change, to 53% after. This study examined the effects of the law change on the likelihood of death, given involvement in a motorcycle crash. Methods: Rates of motorcyclist deaths per crash involvement in Florida for 2001–2002 (after the law change) were compared with those for 1998–1999 (before the law change). Before/after death rate ratios (95% CIs) were examined, and logistic regression models estimated the effect of the helmet law change on the odds of death in a crash, while controlling for rider gender, age, and seating position, and number of vehicles. Results: The motorcyclist death rate increased significantly after the law change, from 30.8 to 38.8 deaths per 1,000 crash involvements. Motorcyclist death rates increased for single- and multiple-vehicle crashes, for male and female operators, and for riders of all ages including those younger than 21. After controlling for gender and age, the likelihood of death given involvement in a motorcycle crash was 25% higher than expected after the law change. It is estimated that 117 motorcyclist deaths could have been avoided during 2001–2002 if Florida's universal helmet law had remained in place. Conclusions:This study provides evidence of the life-saving benefits of universal helmet laws. The results also suggest that age-specific helmet laws are not effective in protecting the youngest drivers. This is not surprising, as these laws are largely unenforceable.
Full‐load route planning for balancing bike sharing systems by logic‐based benders decomposition

Public bike sharing systems require some kind of rebalancing to avoid too many rental stations of running empty or entirely full, which would make the system ineffective and annoy customers. Most frequently, a fleet of vehicles with trailers is used for this purpose, moving bikes among the stations. Previous works considered different objectives and modeled the underlying routing problem in different ways, but they all allow an arbitrary number of bikes to be picked up at some stations and delivered to other stations, just limited by the vehicles’ capacities. Observations in practice, however, indicate that in larger well‐working bike sharing systems drivers almost never pickup or deliver only few bikes, but essentially always approximately full vehicle loads. Many stations even require several visits with full loads. Due to budgetary reasons, typically only just enough drivers and vehicles are employed to achieve a reasonable balance most of the time, but basically never an ideal one where single bikes play a substantial role. Consequently, we investigate here a simplified problem model, in which only full vehicle loads are considered for movement among the rental stations. This restriction appears to have only a minor impact on the achieved quality of the rebalancing in practice but eases the modeling substantially. More specifically, we formulate the rebalancing problem as a selective unit‐capacity pickup and delivery problem with time budgets on a bipartite graph and present a compact mixed integer linear programming model, a logic‐based Benders decomposition and a variant thereof, namely branch‐and‐check for it. For the general case, instances with up to 70 stations, and for the single‐vehicle case instances with up to 120 stations are solved to proven optimality. A comparison to leading metaheuristic approaches considering flexible vehicle loads indicates that indeed the restriction to full loads has only a very small impact on the finally achieved balance in typical scenarios of Citybike Wien. © 2017 Wiley Periodicals, Inc.

Snow Cover Distribution in the Aksu Catchment (Central Tien Shan) 1986–2013 Based on AVHRR and MODIS Data

Variability in snow cover strongly influences mass budgets of glaciers, permafrost distribution, and seasonal discharge of rivers. In times of a changing climate, the spatio-temporal patterns of snow cover are of high interest. In this study, snow cover time series for the Aksu catchment in Central Tien Shan have been generated from optical remote sensing imagery. The analyses span a period between 1986 and 2013 and imbed Advanced Very High Resolution Radiometer (AVHRR) level 1b scenes, which were classified using a dichotomous decision scheme, as well as the preprocessed Moderate Resolution Imaging Spectrometer (MODIS) snow cover product. High congruence of the results could be achieved in spite of different sensors involved. However, a small bias appears especially at high elevations. The results from 2000 to 2013 reveal that snow accumulation begins in October and melting starts in March. Above an elevation of around 5200 m a.s. l. , permanent snow cover can be expected, which is mirrored by a zonal mean of more than 85% of snow for the whole period 1986-2013. Anomalies are very indicative and reveal a high interannual variability of snow cover in terms of quantity and spatial distribution. Change detection of snow cover probability (SCP) shows a slight decrease in lower altitudes up to 4000 m a.s. l. and an opposite trend above. However, the negative trends are not significant. Significant gradients have been found only at high elevations where the two data sources could not perfectly be harmonized. Comparisons with climatic variables show a similar temporal behavior of SCP and temperatures.
The clinicopathological findings of mulberry heart disease in a piglet.

Introduction Selenium-vitamin E responsive conditions have a wide geographic distribution producing a variety of syndromes in poultry, domestic and laboratory animals (3). Feeding diets low in selenium to swine results in lesions of mulberry heart disease, hepatosis dietetica, skeletal muscle degeneration, exudative diathesis and ulceration of the pars esophagus (6). The clinical and pathological entities in swine are well documented (1, 10, 11). Changes in serum enzymes indicative of hepatic and muscular damage occur and are of diagnostic significance on an individual or herd basis (1, 2, 8). Changes in SGOT levels can be detected prior to clinical signs (5, 7), but CPK level is muscle specific and an increased level can be detected up to 21 days prior to the onset of symptoms (5). Treatment of the sow and/or piglet parenterally or in the ration has been used to control the effects of selenium and/or vitamin E deficiency (10, 11). Such treatment was also found to decrease the incidence of mastitis, metritis-agalactia, spraddle-legged and infertility syndromes in subsequent farrowings (10). Treatment also reduced losses of piglets from one to three days of age from colibacillosis and crushing (11).
End System Multicast Protocol for Collaborative Virtual Environments

IP Multicasting has been a crucial requirement of many scalable networked virtual environments by providing an efficient network mechanism through which a sender can transmit its information to a large number of receivers without having to send multiple copies of the same data over a physical link. The widespread deployment of IP Multicast has been slow due to some yet unresolved issues, prompting recent efforts in the development of multicasting protocols at the application layer instead of at the network layer. Most of these protocols address the case of a single source streaming media to a large number of receivers in applications such as video-on-demand or live broadcast. Collaborative and distributed virtual environments exhibit different characteristics that in turn necessitate a different set of requirements for application layer multicast protocols. This paper presents an introduction to application layer multicasting as it relates to distributed and collaborative virtual environments and the development of our own end system multicast protocol for multi-sender virtual teleconference applications.
DRIP - Data Rich, Information Poor: A Concise Synopsis of Data Mining

As production of data is exponentially growing with a drastically lower cost, the importance of data mining required to extract and discover valuable information is becoming more paramount. To be functional in any business or industry, data must be capable of supporting sound decision-making and plausible prediction. The purpose of this paper is concisely but broadly to provide a synopsis of the technology and theory of data mining, providing an enhanced comprehension of the methods by which massive data can be transferred into meaningful information.
Representation of Visuotactile Space in the Split Brain

Recent neurophysiological research in the monkey has revealed bimodal neuronal cells with both tactile receptive fields on the hand and visual receptive fields that follow the hands as they move, suggesting the existence of a bimodal map of visuotactile space. Using a cross-modal congruency task, we examined the representtion ofvisuotactile space in normal people and in a split-brain patient (J. W.) as the right arm assumed different postures. The results showed that the congruency effects from distracting lights followed the hand around in space in normal people, but failed to do so in the split-brain patient when the hand crossed the midline. This suggests that cross-cortical connections are required to remap visual space to the current hand position when the hand crosses the midline.
Optimal Code Set Selection and Security Issues in Spectral Phase-Encoded Time Spreading (SPECTS) OCDMA Systems

In this paper, we perform a thorough analysis of a spectral phase-encoded time spreading optical code division multiple access (SPECTS-OCDMA) system based on Walsh-Hadamard (W-H) codes aiming not only at finding optimal code-set selections but also at assessing its loss of security due to crosstalk. We prove that an inadequate choice of codes can make the crosstalk between active users to become large enough so as to cause the data from the user of interest to be detected by other user. The proposed algorithm for code optimization targets code sets that produce minimum bit error rate (BER) among all codes for a specific number of simultaneous users. This methodology allows us to find optimal code sets for any OCDMA system, regardless the code family used and the number of active users. This procedure is crucial for circumventing the unexpected lack of security due to crosstalk. We also show that a SPECTS-OCDMA system based on W-H 32(64) fundamentally limits the number of simultaneous users to 4(8) with no security violation due to crosstalk. More importantly, we prove that only a small fraction of the available code sets is actually immune to crosstalk with acceptable BER (<;10-9), i.e., approximately 0.5% for W-H 32 with four simultaneous users, and about 1 × 10-4% for W-H 64 with eight simultaneous users.
A strategy for the measurement of homophobia.

This paper attempts to refine and state more clearly an operational definition of homophobia. Homophobia is seen as but one dimension among many that collectively refer to the much larger domain of homonegativeism. The paper then presents a new measure of homophobia, called the IHP, and reports the finding of a study designed to validate the new scale. The IHP was found to have a reliability of . 90 and good content and factorial validity.
