Computer vision is an interdisciplinary field that deals with how computers can be made for gaining high-level understanding from digital images or videos. Fish detection and monitoring is an important topic in computer vision. The growth of high-powered computers, the evolution of high-quality video cameras with low cost and the growing need for automated video analysis have caused more interest in the development of underwater inspection. However, in the sea, the spread of light and sound are not uniform. Therefore, visibility becomes increasingly difficult due to the physical properties of the water. This fact affects negatively of detection accuracy. In this paper, we present method for underwater image enhancement. Dark Channel prior, will be responsible to adjust colour channels in order to get more visibility in images. The algorithm is tested to many images. Experimental results demonstrates a good quality improvement in underwater images.

The use of modern technologies have changed work setting and this change offers us many advantages and benefits. Technology-based communication allows to span time and distance among people. Technology development is moving at such speed that social human behavior science has not kept pace. There is enormous research on human behavior, but we lack new models for guiding managerial practices. The aim of this research is to investigate technologybased communication effect on quality of relationships within the company and the factors affecting it. It was discovered that an important factor is cultural background of the company employees – the communication style and expectations for high context and low context cultures are very different. It is clear that technology-based communication within a company is negatively affecting quality of work relationships it means that new methods should be discovered to power up technology-based communication. IT professionals should include this knowledge in their work in order to improve communication systems.

TFM (Topological Functioning Model) based transformations start from text fragments as inputs and end with source code. Automated processing of use case scenarios is likely to be more predictable than text in a formal style thanks to their structure. The goal of the research is to understand whether the differences in processing these two text forms are essential for getting core elements of a TFM, or even a structured form has essential limitations. The theoretical results illustrate that use case specifications may have more structured and less structured formats. Even in the former format, use case steps may contain explanations and even text fragments in a formal style that increases unpredictability. Analysis of text in the both cases requires part-of-speech tagging, lemmas, constituency and dependency parsing, coreference resolution, and language pattern matching. Thus, structuring the initial documents is questionable but cases when they are to be managed in projects.

SIMILE Project has the aim of supporting the definition of management policies and the operational decisions for the insubric Lakes through an innovative information system based on data from an integrated monitoring system, consisting of remote sensing of water quality parameters of the lakes with latest generation satellite images, buoys equipped with sensors for the continuous detection of limnological and meteorological parameters within the lakes and in the use of additional data on water quality that will be collected through citizen science. Maggiore, Lugano and Como are the lakes involved in the project. This paper presents the satellite monitoring system implemented for the project, based on open data and GIS tools, together with the results obtained in the first 18 months of activities.

To classify latent fingerprint images by using papillary patterns, the proposed method applies the Gabor filter, Haar and Daubechies wavelet transformations, and a multilevel neural network. Numerical experiments were performed, and the results of the proposed solution were compared. The results have shown that we can effectively classify latent fingerprints by applying in combination the Gabor filter, Daubechies wavelet transform of the fifth level, and a neural network.

Many front-end web developers are nowadays increasingly using sassy cascading stylesheets (SCSS) instead of the regular cascading style sheets (CSS). Despite its increased demand, SCSS has inherent complexity which arises from its features such as the use of nesting, inheritance, variables, operators, and functions. In addition, SCSS complexity, like all other software, continually increases with age. High complexity is undesirable because it leads to software that is difficult to understand, modify and test. Although there has been some metrics proposed to measure stylesheets complexity, these were defined in the context of regular CSS, and cannot be used to measure SCSS due to differences in their syntax. This paper proposes four metrics for measuring the complexity of SCSS code. The metrics have been used to calculate the complexity of three code snippets and three real-world projects and were found to be intuitional. The metrics were also evaluated using the Kaner framework and satisfied all the evaluation questions, indicating that they are sufficiently practical as required in the industry. In addition, the metrics were evaluated using Weyuker’s properties, and results show that all the four metrics satisfied seven out of the nine properties, implying that they are theoretically sound.

Many companies are adopting cloud for hosting applications delivered as a service over the Internet. An application service delivered in this way is referred as Software as a Service (SaaS). The SaaS providers get benefits from getting cloud resources provisioned on-demand and through pay-as-you-go billing models. These capabilities enable faster application development and deployment with lower upfront investment into infrastructure. To benefit the most from the cloud, software architecture must be designed with consideration that software will run on the cloud. However, a legacy application is often developed by using monolithic architecture approach and might not get all advantages provided by a cloud computing. A growing monolithic application gets less flexible in development, has longer provisioning time, slows down the speed of innovation and lowers economy of scale. As result of such problems, not only commercial companies, but also the various academic researchers aim to design software as a “cloud-native” application. This kind of software has specific non-functional requirements that define scalability, reliability, fault tolerance and other cloud-specific requirements. This systematic literature review is based on the case studies, published articles and other literature related to the cloud-native or cloud-ready applications. It generalizes common traits of non-functional requirements defined in analyzed resources. Also, it walks through architectural styles of the applications running on a cloud and presents recently developed architectures that are used for large-scale software services delivered on a cloud.
