This paper discusses customization of software product line (SPL) for an unprepared environment and emphasis importance of identifying this risk factor. The SPL can be viewed as a set of applications for similar environments that share many common elements (processes, interfaces, data models, etc.), but it is important that each instance in the SPL application family is also viewed as a consistent and stabile system that has some specific properties, comparing to others. SPL customization - implementing those specific properties should not endanger stability of the common elements and the system as a whole. Very often preparation for the SPL customization is not as serious as for developing a new software product. That can cause SPL customization for a pretty unknown environment which can be unprepared for accepting such software. Environment that is not willing or not capable to accept (or understand) software in its full potential is named unprepared environment, in this paper. Problems that can arise in an unprepared environment can cause that implemented system is unstable or improperly used, which is described through the case study.","PeriodicalId":156236,"journal":{"name":"2016 XI International Symposium on Telecommunications (BIHTEL)","volume":"259 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116027917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the medical images contain diagnostically relevant information, it is necessary for the process of image compression to preserve high levels of image fidelity, especially when the images are compressed at low bit rates. This paper investigates the capacity of an artificial neural network framework for medical image compression. Specifically, the performance of the proposed image compression method is evaluated on a database of computed tomography images of lungs, where PSNR and MSE are used as the principal image quality metrics. The compressed image data is derived from the hidden layer outputs, where the artificial neural networks are trained to reconstruct the network input features. The results of image block segmentation are used as the network training features. The paper proposes the use of Kohonen's self-organizing maps for segmentation of feature space and the use of multiple finely tuned multi-layer perceptrons to achieve an improved compression performance. This paper presents a study on how the choice of block size, network architecture, and training method affect the compression performance. An attempt is made to optimize the artificial neural network framework for the compression of computed tomography lung images.","PeriodicalId":156236,"journal":{"name":"2016 XI International Symposium on Telecommunications (BIHTEL)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117226598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering heterogeneous networks as an inseparable concept from LTE networks nowadays, which remain at position of advanced cellular system, the researchers aim to observe and solve the possible problems of inter-cell interference from the aspect of radio resource management. Hence, the lattermost trends consider heterogeneous networks through the process of connecting energy-efficient small cells to macrocells, due to undeniable importance of energy-efficient solution deployment, which was briefly presented in this paper. Also, the combination of radio resource management and heterogeneous networks turned out to be a practical compound of modern telecommunication techniques and technologies which provides a huge spectrum of possibilities for improving telecommunication services with minimized costs and increased efficiency of the whole system. The concept of radio resource management used in this paper was practically tested by small cells number variation within LTE HetNet set up in NS3 simulation environment.","PeriodicalId":156236,"journal":{"name":"2016 XI International Symposium on Telecommunications (BIHTEL)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132283426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The water level in the lake is influenced by various factors, among which the most important include: the water inflow, discharge of water and water seepage. In this research, artificial neural networks (ANN) are selected for the water level prediction because of their well-known abilities for learning from examples. A total of 29 years of water level measurement data was used for ANN training and validation. This paper represents a sequential approach for the short-term water level prediction in Jablanicko lake by using only water level data. With regard to sequential approach for every step of the prediction, the most recent data were used for ANN training. Two types of ANNs were used in this study: Nonlinear Autoregressive (NAR) neural networks and Feed Forward Back Propagation (FFBP) neural networks. The main focus of this study was on NAR networks prediction of water level, while FFBP networks were used for comparison purposes. The results showed that neural networks can provide quality water level prediction even if only water level data is used.","PeriodicalId":156236,"journal":{"name":"2016 XI International Symposium on Telecommunications (BIHTEL)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133121222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
