PurposeCost and time are two of the primary benchmarks in which construction projects are measured. A variety of factors, however, affect cost and time on construction projects, as identified in previous research. This has led to a need for better understanding how factors affecting cost and time overruns on public construction projects can be managed more efficiently. The purpose of this paper is to address these issues.Design/methodology/approachIn this study 26 factors affecting cost and time overruns on construction projects were identified, through qualitative interviews with project managers from Danish governmental agencies and through a literature review. Through principal component analyses the 26 factors were subsequently narrowed down to four primary latent factors.FindingsThe identified four latent factors affecting cost and time overruns on public construction projects were lack of quality management, lack of project pre-planning, lack of user management and lack of project management.Originality/valuePrevious research has focussed on increasing knowledge by identifying and ranking factors affecting time and cost performance. This has led to the identification of an overwhelming number of factors to use for managing construction projects. The present research reduced the number of factors by clustering them into key latent factors responsible for most of the deviation in performance, narrowing the scope of construction cost and time management into a few tangible key focus areas. This supports and improves fast decision-making that is necessary in a changeable environment such as construction.

In order to solve the problems of poor performance of the recommendation system caused by not considering the needs of users in the process of news recommendation, a news recommendation system based on deep network and personalized needs is proposed. Firstly, it analyzes the news needs of users, which is the basis of designing the system. The functions of the system module mainly include the network function module, database module, user management module, and news recommendation module. Among them, the user management module uses the deep network to set the user news interest model, inputs the news data into the model, completes the personalized needs of the news, and realizes the design of the news recommendation system. The experimental results show that the proposed system has good effect and certain advantages.

This paper presents a solution for remote classes where hardware is offered as a service. The infrastructure was based on Raspberry Pi mini computers to which a set of different developments boards were connected. The proposed software architecture allows students to connect to remote resources and interact with them. Moreover, the services monitoring status of remote resources were introduced to facilitate software development and the learning process. Furthermore, live video feedback is available to visually monitor operation of the resources. Finally, a debugging server was deployed allowing us to establish a remote debugging session between a user’s PC and the dev board on the server premises. The solution offers a comprehensive remote service including user management. Safety risks of the Internet-exposed infrastructure and safety precautions were discussed. The presented RemoteLab system allows students of WUST to gain knowledge, practise and realize exercises in scope of academic courses such as robot controllers and advanced robot control. Thanks to advances in remote education and utilized tools, the RemoteLab was designed and deployed, allowing stationary classes to be substituted with remote ones, while maintaining a high level of class knowledge transfer. Up to the present, the system has been utilized by over 100 students who could realize exercises and prepare for classes thanks to 24 h system availability.

The advantages possessed by proxy and user management applications this can facilitate in managing and monitoring users who are connected to managed hotspots, and can also provide bandwidth limitations for each user according to the limits that we have given to the user profile settings.

In the theory of brand life cycle, there are three stages of brand: entry, growth, maturity and decline. In the initial stage of establishing a brand, the postgraduate entrance examination institution paid a huge cost of human and material resources. When the brand has a little popularity, there is little investment in continuing to expand the popularity, and there is a lack of continuous investment. At present, the brand of the postgraduate entrance examination institution is in the growing period. Maintaining the brand popularity, making it not decline, even more brilliant needs to carry on the brand operation. Brand marketing needs both internal and external innovation of the brand [1], combining the four elements of marketing products, prices, channels and services, and achieving brand maintenance through advertising monitoring, word-of-mouth marketing, user management and other ways. Promote the brand image, increase the brand awareness, and realize the continuous brilliance of the brand. This paper analyzes the problems and causes in the brand construction of postgraduate entrance examination, and puts forward corresponding solutions. This paper analyzes the problems and causes in the process of building the brand, and finds out the rules and ways to build and maintain the brand of education and training institutions.

If you intend on sharing a Dash web app across users, especially in an organizational context, ensure that you amply secure the app and restrict certain functionalities based on the user level. The considerable complexity of user management and privacy varies tremendously from one organization to another, one project to another; thus, there is no universal approach to user authentication.

Markets in which competition thrives are good for both consumers and innovation but, unfortunately, competition is not thriving in the increasingly important cellular market. We propose CellBricks, a novel cellular architecture that lowers the barrier to entry for new operators by enabling users to consume access on-demand from any available cellular operator — small or large, trusted or untrusted. CellBricks achieves this by moving support for mobility and user management (authentication and billing) out of the network and into end hosts. These changes, we believe, bring valuable benefits beyond enabling competition: they lead to a cellular infrastructure that is simpler and more efficient. We design, build, and evaluate CellBricks, showing that its benefits come at little-to-no cost in performance, with application performance overhead between -1.6% to 3.1% of that achieved by current cellular infrastructure.

Distributed data and compute infrastructures aim to provide access to their data or compute services across disciplinary and geographical borders to their users for scientific research. The services are highly collaborative in nature yet independent and shared among multiple scientific communities. Information security and service discovery are two essential functions and precursors for enabling such research collaborations. Given the infrastructure’s heterogeneity in data, compute, or other service offerings, the services often require several kinds of authentication protocols. Moreover, the users bring their own organisational identity and relevant attributes to access the infrastructure services. Should the services’ authentication protocol differ from that of the user’s, the user may not be able to access the target service. Therefore credential translation, attribute harmonisation, scalable trust and authorisation policy management need to be incorporated. In addition to that, enabling service discovery in the federated infrastructures is crucial. Proprietary service registration and query interfaces hinder interoperability across infrastructures. Hence, instead of proprietary and centralised registry approaches, a federated and standard-based registry and discovery model is essential for interoperability across the collaborating infrastructures. This thesis is motivated by a case study consisting of three multi-national research infrastructures: compute (EGI), data management (EUDAT), and a community infrastructure supporting linguistic research (CLARIN). The thesis contributes EMIR, the European Middleware Initiative (EMI) Registry, a decentralised service registry that supports both hierarchical and peer-to-peer topologies and enables collaboration in large-scale infrastructures. The thesis also contributes the B2ACCESS service which implements a proxy model with credential translation and scalable trust and authorisation policy management. Finally, the thesis contributes an integrative architecture realised as a unified cross-infrastructure (or inter-federation) service access framework, which bridges EMIR and B2ACCESS to enable service discovery and access in federated environments., Dreifð gögn og reiknistoðkerfi leitast við að gefa þverfaglegum aðilum, jafnt innlendum sem erlendum, aðgengi að gögnum eða reikniþjónustum til nota við vísindarannsóknir. Reikniþjónusturnar eru samhæfðar en jafnframt sjálfstæðar í eðli sínu, dreifðar um fjöldamörg vísindasamfélög. Upplýsingaöryggi og þjónustuleitir eru tvö nauðsynleg hlutverk og undanfari slíkra vísinda samhæfinga. Vegna þess að stoðkerfin innihalda misleit gögn, reiknigetu, eða annara aðgengilegra þjónustna, þurfa þjónusturnar margar tegundir af auðkenningarleiðum. Ennfremur þurfa notendur að styðjast við auðkenni viðkomandi stofnanna ásamt öðrum viðeigandi eigindum til þess að fá aðgang að stoðkerfisþjónustunum. Ef auðkenningarleið þjónustunnar er frábrugðin frá leið notandans getur hann mögulega ekki fengið aðgang að tilgreindum þjónustum. Þar af leiðandi er þörf fyrir viðbót með skilríkjahliðrun, eigindasamhæfingu, stigfrjálsu trausti og heimildarstjórnun. Þar fyrir utan er mikilvægt að virkja þjónustuleitir í dreifðum inniviðum kerfisins. Innskráning í sérþjónustur og fyrirspurnaviðmót hindrar samvirkni stoðkerfanna. Þar af leiðandi er mikilvægt að styðjast við dreift kerfi byggð á staðlaðri skrásetningu og leitarmódeli í stað miðlægrar skrásetningar fyrir samvirkni á milli ólíkra samhæfðra stoðkerfa. Þessi doktorsritgerð er rökstudd með ferilsathugun sem notast við innviði þriggja fjölþjóðlegra rannsóknastofnanna: reiknistofnun (EGI), gagnaumsýsla (EUDAT), og samfélagsinnviði til styrktar tungumálarannsóknum (CLARIN). Framlag ritgerðinnar er EMIR, skráarsafn (e. registry) fyrir European Middleware Initiative (EMI), ómiðlæg þjónustuskrá sem styður bæði stigveldis grannfræði og deilitækni og býður upp á samvinnu í stórtækum innviðum. Að auki er framlag þessarar ritgerðar einnig B2ACCESS þjónustan sem nothæfir vefselsmódel með skilríkjahliðrun og stigfrjálsu trausti og auðkennisreglustýringum. Að lokum er framlag þessarar ritgerðar einnig samþætt högun innleidd sem þjónstuumgjörð um samtvinnaða margþætta innviði sem brúa EMIR og B2ACCESS til að leyfa þjónustuleit og aðgang í dreifðu sambandsumhverfi.
