JavaScript ja takaisinkutsut suomalaisilla verkkosivuilla : takaisinkutsumenetelmän yleisyys ja ongelmat

2016

JavaScript on hyvin paljon käytetty ohjelmointikieli ja verkkosivuilla vallitsevassa asemassa. JavaScript-kieliset ohjelmat sisältävät kuitenkin paljon virheitä. Verkkokeskusteluissa ”takaisinkutsuhelvetti”, eli tilanne jossa ohjelmakoodi on monien sisäkkäisten takaisinkutsullisten funktioiden vuoksi hyvin vaikesti ymmärrettävä ja hallittava, nostetaan yhdeksi kielen kipupisteistä. Tässä tutkimuksessa tutkittiin kirjallisuudesta JavaScriptin takaisinkutsumenetelmään liitettyjä ongelmia sekä sitä korvaavia asynkronisen toiminnan menetelmiä. Empiirisessä tutkimuksessa kartoitettiin suomalaisten verkkosivujen JavaScript-ohjelmakoodia. Ohjelmakoodin määriä, sijaintia ja ominaisuuksia mitattiin.…

A hybrid network for maritime on-board communications

2012

Current maritime on-board communications have to be enhanced for safety and security, where ubiquitous technologies can help, together with providing comfort and convenience to the crew and passengers. Employing wireless sensor networks on board is one recent practice of implementing ubiquitous technology for ships, where further study is needed because of the connectivity challenges. Meanwhile, it is important for an on-board communication system to be reliable and flexible for handling emergency situations. In this paper, we propose a solution of employing ubiquitous technology on ships in a way that both connectivity and emergency handling are examined. Two key aspects of this proposal a…

The compendium of self-enactable techniques to change and self-manage motivation and behaviour v.1.0.

2019

Behaviour change techniques describe the content of behaviour change interventions, but do not adequately account for the actions that people must themselves undertake to successfully change or self-manage motivation or behaviour. This paper describes the development of a compendium of self-enactable techniques, combining behaviour- and motivation-regulation techniques across six existing classifications of behaviour change techniques and three scoping reviews. The compendium includes 123 techniques, each of which is labelled, defined and presented with instructive examples to facilitate self-enactment. Qualitative feedback was gathered from intervention developers and the general public to…

Integration of IT Applications in Local Government Computer Systems

2015

Integration of IT applications in companies has always been a hot topic in recent years, leading to the creation of a new working style in the software: Enterprise Application Integration. To present the essence and very detailed image of this, is a main purpose of the paper. After a literature review, authors have described a chosen system, which is being used by the local government entities. The first part of the article traces the evolution of embedded computing applications management companies and the problems that were inevitable faced during the integration efforts. Then, in the article, the infrastructure of EAI is presented, with the detailed description of its: Front, Back, Middl…

Adaptation of elaborated feedback in e-learning

2008

Design of feedback is a critical issue of online assessment development within Web-based Learning Systems (WBLSs). In our work we demonstrate the possibilities of tailoring the feedback to the students’ learning style (LS), certitude in response and its correctness. We observe in the experimental studies that these factors have a significant influence on the feedback preferences of students and the effectiveness of elaborated feedback (EF), i.e. students’ performance improvement during the test. These observations helped us to develop a simple EF recommendation approach. Our experimental study shows that (1) many students are eager to follow the recommendations on necessity to read certain …

Customer Relationships Management in Organizations

2013

Abstract In recent years, the market for on-demand CRM applications suffered especially in the segment of small and medium companies because of the concerns about the cost and the complexity of on request implementations. CRM on demand is a good choice for companies that want to implement standard processes that can use data structures “out of box” with little or not at all internal IT support and does not require complex or real-time integration with back office systems. However, on-demand CRM software is not always as simple as vendors want us to believe. Customizing can be problematic and interface tools of CRM vendors can not provide desired levels of integration. Implementing a hosted …

FCA-based knowledge representation and local generalized linear models to address relevance and diversity in diverse social images

2019

Abstract In social image retrieval, the main goal is to offer a relevant but also diverse result set of images to the user. To address relevance and diversity at the same time, we propose a multi-modal procedure. This approach deals with the diversification problem using a two-step procedure based on the application of Formal Concept Analysis (FCA) to organize the text content of the images, followed by a Hierarchical Agglomerative Clustering (HAC) step to find the topics addressed by the images. FCA detects the latent concepts covered by the images in the result set, organizing them according to these concepts. In the second step, clustering is carried out to group together the ones with a…

Variance estimation and asymptotic confidence bands for the mean estimator of sampled functional data with high entropy unequal probability sampling …

2013

For fixed size sampling designs with high entropy it is well known that the variance of the Horvitz-Thompson estimator can be approximated by the H\'ajek formula. The interest of this asymptotic variance approximation is that it only involves the first order inclusion probabilities of the statistical units. We extend this variance formula when the variable under study is functional and we prove, under general conditions on the regularity of the individual trajectories and the sampling design, that we can get a uniformly convergent estimator of the variance function of the Horvitz-Thompson estimator of the mean function. Rates of convergence to the true variance function are given for the re…

Image Quality Assessment Based on Intrinsic Mode Function Coefficients Modeling

2011

Reduced reference image quality assessment (RRIQA) methods aim to assess the quality of a perceived image with only a reduced cue from its original version, called ”reference image”. The powerful advantage of RR methods is their ”General-purpose”. However, most introduced RR methods are built upon a non-adaptive transform models. This can limit the scope of RR methods to a small number of distortion types. In this work, we propose a bi-dimensional empirical mode decomposition-based RRIQA method. First, we decompose both, reference and distorted images, into Intrinsic Mode Functions (IMF), then we use the Generalized Gaussian Density (GGD) to model IMF coefficients. Finally, the distortion m…
