A Versioned Approach to Web Service Evolution

Applications based on micro-services or web services have had a significant growth due to the exponential increase in the use of mobile devices whose applications rely almost entirely on this type of interfaces. However, using an external interface comes with no guarantees to the developers using it. Changes may be introduced at any moment, which can break the software that is using those APIs. It is necessary to give the consumers guarantees that their software will not break, but not at the expense of stagnating the development of said web service. In this document we present a programming model to evolve web services in a sustainable way and to automate most of the maintainability that might be required by the consumer. This model works by allowing multiple versions to be deployed, and then using a relation containing metadata to type check versions. By doing this, it is possible to guarantee type safety between all the versions to provide a sustainable way to evolve the service. A prototype framework was implemented in JavaScript, where it is possible to visualize the model working in an environment similar to what it is used in the industry nowadays. Finally we present a comparison of our prototype with the state of the art, thus demonstrating that our solution presents a viable method of evolution of web services.
Usability evaluation of menu interfaces for smartwatches

ABSTRACT Currently, there are various smartwatch products on the market, and the number of users is expected to continue to increase. The functions of smartwatches have also been diversified, and the amount of information displayed on their screens is also increasing. However, as there are many restrictions on the rather small screen size, it is difficult to apply the methods used to provide information on the existing smart devices. Therefore, this study investigated how menu should be provided on the touch screen of smartwatches and derived a more effective menu structure. For our purposes, we conducted two experiments. In the first experiment, we provided 40 items in grid view and list view layout styles and tried to search for a given item by scrolling or paging. Efficiency was higher for the list view layout, in which many items were displayed on the screen and task completion time was shortened. However, the overall satisfaction was higher for the grid view layout, in which fewer items were displayed on the screen. In the second experiment, we derived an efficient menu structure when displaying hierarchical items that could be grouped into upper and lower categories. Likewise, many items on a single screen were excellent in terms of task completion time and efficiency. Providing depth of menu by categorization showed satisfactory results in task completion time, efficiency, and overall satisfaction.
Botnets and Cyber Security: Battling Online Threats

The Internet, originally designed in a spirit of trust, uses protocols and frameworks that are not inherently secure. This basic weakness is greatly compounded by the interconnected nature of the Internet, which, together with the revolution in the software industry, has provided a medium for large-scale exploitation, for example, in the form of botnets. Despite considerable recent efforts, Internet-based attacks, particularly via botnets, are still ubiquitous and have caused great damage on both national and international levels. This chapter provides a brief overview of the botnet phenomena and its pernicious aspects. Current governmental and corporate efforts to mitigate the threat are also described, together with the bottlenecks limiting their effectiveness in various countries. The chapter concludes with a description of lines of investigation that could counter the botnet phenomenon.
Observation of Auditory Perceptual and Visual-Spatial Characteristic of a Patient with Hemangiopericytoma in Occipital Lobe: A Magnetoencephalography (MEG) study

The present study discussed functional reorganization and alteration in respond to the slow-growing tumour, hemangiopericytoma in the occipital cortex. Visual evoked field (VEF) and auditory evoked field (AEF) using magnetoencephalography (MEG) was used to evaluate the source localization and brain activity. Results of VEF source localization show a typical brain waves. Brain activity of the occipital lobe demonstrate low activation in the ipsilateral to the tumour. However, result shows the activation on the contralateral hemisphere was high and bigger in activation volume. AEF result shows an identical source localization and both side of the temporal lobe are activated. This result suggests that there is a positive plasticity in auditory cortex and slow-growing tumour can induce functional reorganization and alteration to the brain.

IWT Based Remote Authentication Via Biometrics

: In remote communications data is as often as possible exchanged, requiring remote confirmation. Remote verification includes the accommodation of encrypted data, alongside visual and sound prompts (facial pictures/recordings, human voice and so on.). Trojan Horse and different assaults can bring about genuine issues, particularly in instances of remote examinations (in remote studying) or meeting (for personal hiring). This paper proposes a powerful authentication in view of semantic division, blowfish encryption and data embedding. Accepting that client X needs to be remotely authenticated, at first X’s video frame (VO) is naturally fragmented, utilizing a head and-body finder. Next, one of X’s biometric signs is encrypted. Next, the encrypte signal is embedded to the most significant wavelet coefficients of the VO, utilizing its Qualified Significant Wavelet Trees (QSWTs). QSWTs give both imperceptibility what’s more, critical resistance against lossy transmission and compression, conditions that are regular in remote systems. At last, the Inverse integer Wavelet Transform (IIWT) is applied to give the stego-object(SO).
TO WIDEN THE NOVEL CLOUD CARGO SPACE EXAMINE FOR LOCATION

Watching that during hundreds of sensing situations, the location statistics is probably positioned up-processed as quickly because the facts are submitted to a few server, we format Cloud-Offloaded Gps navigation (CO-Gps navigation) solution that permits a sensing tool to strongly obligation-cycle its Gps navigation receiver and log sufficient uncooked Gps navigation signal for publish-processing. Location is, in reality, essential provider for traveling with a computer. Typical Gps navigation receivers, despite the fact that substantially without a hassle to be had for navigation reasons may additionally eat too much electricity to end up using for lots of programs. Localization is simply an essential carrier of mobility. In outside packages as an instance natural international tracking, participatory ecological sensing, and private standard fitness applications, Gps navigation is affects the maximum common region sensor. Leveraging overtly to be had records, for example, GNSS satellite TV for pc television for computer ephemeris further to an Earth elevation database, a cloud issuer can derive pinnacle splendid Gps navigation locations from a couple of milliseconds of uncooked information. Using our fashion of a portable sensing device platform known as CLEON, we decide the precision and efficiency of the solution. In comparison to extra than thirty seconds of heavy sign processing on standalone Gps navigation receivers, we're capable of achieving three orders of significance decrease electricity intake consistent with vicinity marking.
Student Affairs Practitioners' Leadership on behalf of Undocumented College Students in the USA

The United States is considered a country of immigrants that has historically hosted people from all over the world. Oftentimes, immigrants struggle to find and shape an American identity, especially when it comes to undocumented youth (Gonzales, 2008). New waves of immigrants to this country trigger feelings of fear concerning the loss of national identity and the lack of cultural incompatibility (Kim & Díaz, 2013a). In this sense, the emergence of anti-immigration attitudes has been in the political, social, and economic agenda over the last years. As a result, postsecondary institutions have been constantly looking for accomplishing social progress and growth (McDermott, 1973); however, there are still gaps to fill in at institutions with respect to create a welcome atmosphere and campus-wide acceptance for all students. In particular, undocumented students which the National Immigration Law Center defined as “a foreign national who: (1) entered the United States without inspection or with fraudulent documents; or (2) entered legally as a nonimmigrant but then violated the terms of his or her status and remained in the United States without authorization” (as cited in Educators for Fair Consideration, 2019) face socioeconomic and institutional barriers. Therefore, it deems necessary to find appropriate services and allocate resources that help undocumented students cope with difficulties concerning both their college adjustment and personal struggles reaching a holistic development (Gildersleeve &Ranero, 2010). The purpose of this paper is to address the topic of undocumented students as it relates to their college persistence. In particular, four leadership theories help highlight the important role of student affairs practitioners to become advocates and seek social justice for this unique student population.The organization of the manuscript encompasses the following sections. First, a brief literature review concerning federal and state legislation on undocumented students is presented. Then, an overview of student affairs practitioners’ importance to promote a positive college climate and better serve this student population is addressed. The aforementioned section includes four leadership theories, which student affairs professionals could adopt. Next, an outline addressing the social justice aspect on behalf of undocumented students is introduced. Finally, a section covering recommendations for student affairs professionals is proposed yielding the conclusion.
Predictive Shutdown Systems for Nuclear Power Plants

This dissertation investigates the use of a Kalman filter (KF) to predict, within the shutdown system (SDS) of a nuclear power plant (NPP), whether a safety parameter measurement will reach a corresponding trip set-point (TSP). The proposed predictive SDS (PSDS) designs aim to initiate shutdown actions at a time which is earlier than conventional shutdown initiation. These early detections are, in turn, expected to improve safety and productivity margins within the NPP. The KF-based point-PSDS design utilizes a linear time-varying (LTV) system model to predict mean safety parameter measurements for comparison against the TSP. The KF considers noise covariances that either have assumed predetermined values, or are estimated online using an adaptive limited memory filter (ALMF). The PSDS is enhanced to consider, by recursive least squares (RLS) estimation, conditions that are uncertain with respect to the assumed system model and noise properties. The result is a KF/RLS-based PSDS that compensates for prediction error by RLS-based estimation of deterministic disturbances to the system state and measurement. The PSDS is further enhanced to calculate confidence intervals for the predictions as a function of the propagated error covariance. This enhancement results in interval-PSDS designs that consider confidence in an impending condition by comparing predetermined confidence interval bounds against the TSP. Finally, an optimal-PSDS design is formulated to adapt the effective prediction, e.g. horizon or bias, by limiting and minimizing the probability of missed and false trip
Factor affecting consumers intention to purchase organic food: Empirical study from Malaysian context

This paper investigates the factors that affect consumers purchase intention of organic food by integrating self-identity and environmental concern into the theory of planned behaviour (TPB). Data were collected with questionnaires in five shopping malls in the Klang Valley, Malaysia. SPSS and structural equation modelling, specifically, partial least square, were used to analyse the data. The findings show that attitude, subjective norm, perceived behavioural control, self-identity and environmental concern have a significant positive effect on consumers purchase intention. Furthermore, purchase intention is found to mediate the relationship between attitude, subjective norm, perceived behavioural control, self-identity and environmental concern with purchase behaviour. From a practical point of view, the results provide insight for producers and marketers to develop and adapt products and marketing campaigns to establish a positive perception towards organic food products.
Cascaded camera motion estimation, rolling shutter detection, and camera shake detection for video stabilization

Easy-to-use online video stabilization system and computer implemented video stabilization methods are described. Video that is captured after stabilization, thus stabilizing acts for all types of video scenes including a video capture both the legacy and the latest video. In one implementation, the video stabilization system is a fully automatic then, does not require any input or parameter setting by users other than the video itself. Video stabilization system using cascaded motion model (cascaded motion model), selects a correction to be applied to different frames of video. In various implementations, the video stabilization system may detect and compensate for the high frequency jitter artifacts, low frequency artifacts shaking, rolling shutter artifacts, large motion in the foreground, poor lighting, scene cut, and a long and a short video of the two.

LA FENOMENOLOGÍA DE LA AFECTIVIDAD DE DIETRICH VON HILDEBRAND: UNA PROVOCACIÓN CORDIAL PARA LA TEOLOGÍA

In the present study, I would like to recover the phenomenology of a thinker that remains still undiscovered in the Ibero-American realm. Dietrich von Hildebrand (1889-1977) was born the same year as Martin Heidegger, and was a disciple of Max Scheler and Edmund Husserl, working brilliantly in his phenomenological method. I am not going to explain here the fundamental phenomenology of this author but his phenomenology as it is applied to affectivity, in order to subtly provoke theology. This paper, then, is going to take notice of a special phenomenology and not of a general one, by dedicating our efforts to the personal quality of a diverse and unified affectivity.
Condolences and Empathy in Online Communities

Offering condolence is a natural reaction to hearing someone's distress. Individuals frequently express distress in social media, where some communities can provide support. However, not all condolence is equal—trite responses offer little actual support despite their good intentions. Here, we develop computational tools to create a massive dataset of 11.4M expressions of distress and 2.8M corresponding offerings of condolence in order to examine the dynamics of condolence online. Our study reveals widespread disparity in what types of distress receive supportive condolence rather than just engagement. Building on studies from social psychology, we analyze the language of condolence and develop a new dataset for quantifying the empathy in a condolence using appraisal theory. Finally, we demonstrate that the features of condolence individuals find most helpful online differ substantially in their features from those seen in interpersonal settings.
On the existence of positive solutions for a nonhomogeneous elliptic system

The nonhomogeneous part must satisfy a suitable positiveness condition, but it may change sign. Mathematics Subject Classification (2000). Primary 35J55.
Assessing Canadian Business IT Capabilities for Online Selling Adoption: A Net-Enabled Business Innovation Cycle (NEBIC) Perspective

After the authors of this study encounter a series of peculiar examples of products and services that are not normally sold online in Canada, the authors assess the psychometric properties of net-enablement capability, as an internal rather than external factor, regarding the decision to implement online selling tools as technology innovation to achieve growth. According to the literature, other authors rarely consider internal factors when they assess the relationship between technology adoption and business model innovation. The study contributes to the continuous dialogue involving the Net-Enabled Business Innovation Cycle (NEBIC) model by analyzing online sellers and offline sellers in Canadian sectors with below-average rates of online selling adoption. The findings indicate that net-enablement capability is a significant internal factor that positively affects innovation in business models for Canadian online sellers across different sectors regardless of the level of online selling adoption rate.
Users' perception of ease of use (EOU) and confidence with skill using SMS in emergency conditions

The aim of this paper is to investigate the correlation between ease of use (EOU) and confidence with skill with regard to the use of SMS (Short Messaging Service) for warning messages in an emergency situation. This paper is part of our formative study to investigate the possibility for using SMS in emergency conditions from the users' perspective. The case study that we used was warning messages for an urban kampung flood disaster area in Indonesia. We analysed the users' perception of EOU and confidence with skill when using SMS. This study collected data from 350 participants who live in a flood prone area in Bandar Harjo, Semarang, Indonesia. The data indicated a strong and positive correlation between EOU and confidence with skill for using SMS in emergency conditions. The users' gender, age and level of education influence the strength of the correlation coefficients between EOU and confidence with skill. The users' frequency of use (FOU) did not influence the strength of the correlation coefficients between EOU and confidence with skill.
Theoretical basis for at‐many‐stations hydraulic geometry

At‐many‐stations hydraulic geometry (AMHG) is a recently discovered set of geomorphic relationships showing that the empirical parameters of at‐a‐station hydraulic geometry (AHG) are functionally related along a river. This empirical conclusion seemingly refutes previous decades of research defining AHG as spatially independent and site specific. Furthermore, AMHG was the centerpiece of an unprecedented recent methodology that successfully estimated river discharge solely from satellite imagery. Despite these important implications, AMHG has remained an empirical phenomenon without theoretical explanation. Here we provide the mathematical basis for AMHG, showing that it arises when independent AHG curves within a reach intersect near the same values of discharge and width, depth, or velocity. The strength of observed AMHG is determined by the degree of this convergence. Finally, we show that AMHG enables discharge estimation by defining a set of possible estimated discharges that often match true discharges and propose its future interpretation as a fluvial index.
A Simulation of a Networked Video Monitoring System Using NS2

The work presented in this paper has focused on the simulation of video streaming over a hybrid (wired-wireless) network for the purpose of monitoring. A simulation scenario has been designed and implemented using the network simulator (NS2) to realise the network system. The system consists of 5 nodes, 3 of which are video cameras that play two major roles. First of all, capturing moving objects within a radius of 20 metres and secondly to work as a wireless routers within the network. Furthermore, the two nodes have different purposes; the fourth node works as an access point to connect the cameras which are wirelessly connected together and with the access point. However, the fifth node performs the job of a server which is wired-connected to the access point and has the video encoding/decoding and quality of service (QoS) calculations routines.The system has been implemented and tested under simulation environment and two types of assessment have been performed. The first assessment was to measure the quality of service from a networking point of view for which three factors have been used; namely: Packet Loss, End-to-End Throughput and Jitter. The second assessment was to measure the quality of the received videos using Peak signal to Noise Ratio "PSNR" measure. For simulation purposes 3 videos of type H.264 have been used to represent the 3 cameras streams. Evalvid framework is used to transform them into a streaming format to facilitate the evaluation of video streaming over a simulated network. The simulation process has shown a promising results in both network's QoS and video quality with the average packet loss of 0.04%, average time delay of 0.9sec and average jitter of 0.001951. More after, the video quality has shown an average "PSNR" of 30.13 when 1530 frames have been transmitted with STDV of 6.85.
The influence of pedalling frequency on mechanical efficiency in exercices with the same intensity

The aim of this work was the determination of the pedalling rate on the gross and net mechanical efficiency in efforts with the same intensity (250 W) as well as checking if the HR grows linearly along with the pedalling rate. Twelve students of AWF took part in the study. Examined subjects performed four, lasting for 3 min efforts on a cycle-ergometer (Monark E 824) joined with the computer. Exercises were done with the space of 7 days between them. The effort load equalled 250 W and the amount of performed mechanical work – 45 kJ. The pedalling rate amounted in efforts 40, 60, 80, 100 rotations per min respectively. The gas analyser (SensorMedics company) with 2900/2900c Metabolic Measurements Cart/System programme was used as for the determination of the oxygen intake during exercises and while resting (until the resting value of VE occurs). The gross mechanical efficiency (GE) was calculated as a mechanical work and total energy ratio and the net mechanical efficiency (NE) as the mechanical work and total net energy ratio (the total energy diminished by the resting energy value). Pulse measurement was calculated during and after every effort using the POLAR-SportTester. A capillary blood was taken from a fingertip to the heparinized capillary tubes as for the estimation of an acid-alkali balance. It was done before the effort, immediately after it and in every 2 min of the 8 min rest. Following acid-alkali balance values were analysed in the blood gas analyser Ciba-Corning 248: BE, HCO3act, pCO2, pH. Average (±SD) mechanical efficiency gross values for pedalling rate of 40, 60, 80 and 100 rpm equalled respectively: 14.2±2.2, 14.9±2.6, 15.3±2.1, 12.3±1.5% and net values: 21.8±2.8, 22.6±2.1, 23.1±2.1, 19.0±2.7%. Gross and net values obtained by 100 rpm were significantly different from averages reached by 40, 60 and 80 rpm. In case of the pulse value the minimum HR occurred by the pedalling rate of 60 rpm. However, in the case of ∆HR (difference between HR value observed in the test and the resting one) the circulatory system reaction grew along with the pedalling rate. The HR values obtained by various pedalling rates did not differ crucially. (Biol.Sport 21:51-66, 2004)
