Recommender systems have attracted much attention in last decades, which can help the users explore new items in many applications. As a popular technique in recommender systems, item recommendation works by recommending items to users based on their historical interactions. Conventional item recommendation methods usually assume that users and items are stationary, which is not always the case in...
Software engineering code of ethics (SWECOE) is an area within software engineering that requires increasing research attention. SWECOE is acknowledged as an important area of practice that has a huge impact on how software affects our daily life. The degree of harm to the users as a result of using equipment with faulty software applications highly depends on the ability of software engineers to...
This paper presents the current problematic of development a set of indicators user direction, informational direction and reputational direction to perform task of directions of the organization of life cycle of virtual community. The method of determination of possible variants of balancing indicators of virtual community is developed. These indicators based on the analysis of the subject area of...
The basic indicators of the life cycle of technology were analyzed and the generalized system for the evaluation of the life cycle phase is allocated. Indicators are considered as properties that technology must have to fit a certain stage of its existence. The existing approaches of technology development analysis were studied. The generalized classification, which is a list of indexes for the proper...
Block chain technology has become a hot research in recent years, and its development will affect the whole society. In this paper, the new Life Cycle model of Power Internet Financial Products was proposed under the Block Chain effects. Some results are based on econometric mathematical model and economic principles. Meanwhile, we predict the lifecycle curve of Internet financial products based on...

This document provides a mapping of ISO/IEC/IEEE15288:2015,...
The purpose of this article is to present the methodology of creation of multi-aspect models of system objects that can be used at all stages of the life-cycle. Multi-aspect modeling are based at a technology of engineering of knowledge, the cybernetic approach and the methodology of object-oriented programming. The article presents the results of research in the field of multi-aspect modeling, the...
In hyperspectral classification, derivative of reflectance spectra is used directly or by fusion with reflectance spectra. In this way, classification performance is improved. However, on the land cover, especially for plant species, the reflectance spectra may exhibit differences in course of plant age and plant maturity level. This situation makes traditional classification methods which are based...
Big data has penetrated into various industries and business functions, and become important factors of production in the global economy. In the big data technology system, big data collection is the basis. The storage, analysis, integration and visualization of unstructured data and semi-structured data will become an important focus of the big data innovation. Traditional structured data will no...
Sixty years ago, in 1956, the first explicit representation of a software development life cycle model was presented by Herbert Benington. Since then, software development life cycle models have come a long way, and the current article provides an overview of that development.
This paper presents a decision analysis technique for conducting Analysis of Alternatives (AoA) at the end of the Materiel Solution Analysis (MSA) phase of the United States (US) Department of Defense (DOD) acquisition process. This modified fuzzy Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is designed to provide Decision Makers (DM) with a tool to evaluate concept alternatives...
This paper illustrates the Battery Life Cycle Tester with intelligent charging and discharging unit comprising of measurement, data logging, remote monitoring and communication sections for data acquisition and control. The life cycle tester switches between different charging and discharging modes making it compatible with all battery chemistries. The discharger comprises of an electronic load using...
A new method of Highly Accelerated Stress Screen/Life Testing (HASS/HALT) for computer keyboards is introduced and compared with User Information Investigation (UII) from manufacturer, Accelerated Life Testing (ALT), and Normal Stress Reliability Testing (NSRT). The results of the above three lab testing processes all showed good accordance trends with the data from the UII. The failure mechanism...
This paper presents the current problem of tasks performance of the life cycle directions of virtual communities. Nowadays, virtual communities form a unique content that is the actual source of information and its effective exchange. The analysis of virtual communities' creation as a project, organization of the life cycle is presented by using the network planning. The article presents the execution...
Recently embedded Vacuum Circuit Breakers (VCB) with thermoplastic have been introduced on the market. The substitution of epoxy resin by thermoplastic is of concern in ambient air insulated switchgear solutions. This paper reports a study performed for VCB embedded poles with two technologies: epoxy resin and engineering thermoplastic PA66. A comparison is made between both technologies reagarding...
According to the information management value of construction project based on Building Information Modeling up to now, a general structure of Building Information Modeling (BIM) based platform for life cycle information management is established and detailed implementations in construction projects are given. The general structure of BIM based information management platform is investigated in detail...
In the increasingly dynamic realities of today's software systems, it is no longer feasible to always expect human developers to react to changing environments and changing conditions immediately. Instead, software systems need to be self-aware and autonomously adapt their behavior according to their experiences gathered from their environment. Current research provides role-based modeling as a promising...
For C++ programs often appear memory leaks, cross-border access memory and memory does not match the release of error, we have analyzed existing memory error detection tools and methods, implemented in the Linux platform to run the memory testing tool MemDetect prototype based on the open source dynamic instrumentation-Valgrind using function family's memory information block management method and...
The evolution of the harmonized set of ISO/IEC/IEEE 15288-12207 related standards and technical reports that are discussed in this International Standardprovides detailed requirements and guidance on the application of system life cycle processes. This International Standard unifies technical and managementrequirements and guidance from several of these sources to specify the requirements for the...
