Therefore, the structure of an IT organization is fundamental. However, despite the recognized importance of IT organizational structure and the efforts made in the development of disparate perspectives and relationships, no relevant references about its structure are found, and the existent ones are far from satisfactory. There is neither a single framework nor one relating to what we consider to be relevant or clearly dominant. This paper proposes the use of ontology engineering methodology to identify and enumerate concepts and develop a conceptual framework in order to structure and establish a relationship among concepts within an IT organization, which will allow the definition of an IT organization.","PeriodicalId":194465,"journal":{"name":"DCNET/ICE-B/OPTICS","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116107907","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}

We propose a methodology to support the decisionmaker in orienting, planning, and evaluating multiple (partially overlapping) interventions. In particular, we address two main problems: first, how to decide the structure of the interventions and how to determine the relevant parameters involved; second, how to set up a scoring system for comparing single interventions and its extension to the case of multiple interventions. The methodology unexpectedly shows that i is not always the case that the best outcome is the one obtained by the best projects . We formally model the problem and discuss its computational complexity. Our approach is also effective in process of selecting, from a set of submitted proposals, the ones to be funded.","PeriodicalId":194465,"journal":{"name":"DCNET/ICE-B/OPTICS","volume":"33 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128733162","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 data are inserted and numbered into customized size relations at a predefined order. The server ability to create a full, regular Broadcast Plan (RBP) with single and multiple channels after some data transformations is examined. The Basic Regular Algorithm (BRA) prepares an RBP and enables users to catch their items while avoiding wasting energy by their devices. In the case of multiple channels a dynamic grouping solution is proposed, called the Partition Value Algorithm with Less Dimension (PVALD), under a multiplicity constraint. In order to provide an RBP under relative delays a Dimensioning Algorithm (DA) is developed. The DA, with the criterion of ratio, offers the differentiation of service. This last property, in addition to the self-monitoring, and selforganizing, can be offered by servers today providing also channel availability and lower energy consumption by using a smaller, number of channels, of equal bandwidth. Simulation results are provided.","PeriodicalId":194465,"journal":{"name":"DCNET/ICE-B/OPTICS","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133276679","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 main goal is to make the user interface so simple that the end users can concentrate on their tasks – not on the handling of the application, the main challenge is its adaptation to the context. A possible solution is smart adaptation. Consequently, developers need to know the limits of both context and systems and must be aware of mobile end users different interaction.

Their special architecture allows for unique applications that would be impossible, or at least very difficult, to implement using other technologies. But the wireless data transmission between the single nodes poses new challenges from a security point of view: the single messages have to be secured against eavesdropping and manipulation, as well as the individual nodes have to be secured against capture and extraction of their secret key. Cryptographic hash functions are an integral part of most cryptographic network protocols, whether they are used for signatures or message integrity. In this position paper, we describe a preliminary performance evaluation of three very different hash-functions on a Texas Instruments CC2530 sensor node, based on an 8051 microcontroller: Tiger, representing a hash designed for 64-bit architectures, the current standard SHA-1, and Grøstl, a SHA-3 finalist. Our preliminary results indicate that even without any major optimizations hash algorithms that were clearly not designed to run on constrained devices can be adapted to these environments with quite acceptable results, thereby giving designers of sensor network security protocols new implementation options.","PeriodicalId":194465,"journal":{"name":"DCNET/ICE-B/OPTICS","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124440512","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}
