    Offering software as a service: Case study of system integrators

    Get PDF
    The software markets are moving from product-based business towards more service-oriented business. System Integrators (SIs) have also noted the service component\u27s increase in their customer cases and are placing more resources in their own service development. This study is focused on the SIs and the objective of this paper is to study how the integrators can use the Software as a Service (SaaS) business model in order to provide online services successfully to their customers and how they can take advantage of the associated benefits while overcoming the challenges. To providers, SaaS offers e.g. scale economies in distribution and administration costs, expansion of the potential customer base, and recurring revenue. From the customer viewpoint, SaaS services e.g. enable them to focus on their core competencies, provide easier access to technical expertise, and offer economical access to valuable software applications independent of time and location. We conducted a case study of six integrators and our findings confirm that the SIs are getting better in taking advantage of the SaaS model’s benefits, i.e. they are achieving scale and scope economies, have shortened their sales cycle, and expanded their potential customer base. The SIs are also solving or downplaying the associated challenges e.g. by placing more emphasis on scalability and customisation capabilities, and partner management

    Mobile Security as a Service

    The purpose of this paper is to study how a software product company can expand its product-based business with the Software as a Service (SaaS) model in the mobile setting. In this research study we examine how the SaaS model can be implemented by a software company with existing PC-based software business and conduct a case study on F-Secure and its mobile security as a service offering. The differences between the product and service business are considerable and the change of focus from one to the other is not easily done. For example, the scale economies, which are associated with product business, are not easily achieved in service business. However, the SaaS business model has many benefits to offer to SaaS providers. To providers, SaaS offers e.g. expanded customer base, lowered production and distribution costs, more predictable cash flows, and shortened sales cycle.Our findings include that by successfully solving the risks associated with the SaaS model and by fulfilling the customers’ demands of customization and at the same time benefiting from economies of scale, scope, and aggregation, F-Secure has managed to leverage its domain area expertise with its SaaS offering: F-Secure has expanded its PC-based antivirus and security application business to cover also mobile devices. F-Secure has also increased its potential customer base amongst smart phone users (both end-users and businesses) with the help of its partners: mobile operators and handset manufacturers

    Development of 3D CAD/FEM Analysis System for Natural Teeth and Jaw Bone Constructed from X-Ray CT Images

    A three-dimensional finite element model of the lower first premolar, with the three layers of enamel, dentin, and pulp, and the mandible, with the two layers of cortical and cancellous bones, was directly constructed from noninvasively acquired CT images. This model was used to develop a system to analyze the stresses on the teeth and supporting bone structure during occlusion based on the finite element method and to examine the possibility of mechanical simulation

    The first observation of a new b baryon via its strong decay into Xi(b)^- pi^+ (plus charge conjugates) is reported. The measurement uses a data sample of pp collisions at sqrt(s) = 7 TeV collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 5.3 inverse femtobarns. The known Xi(b)^- baryon is reconstructed via the decay chain Xi(b)^- to J/psi Xi^- to mu^+ mu^- Lambda^0 pi^-, with Lambda^0 to p pi^-. A peak is observed in the distribution of the difference between the mass of the Xi(b)^- pi^+ system and the sum of the masses of the Xi(b)^- and pi^+, with a significance exceeding five standard deviations. The mass difference of the peak is 14.84 +/- 0.74 (stat.) +/- 0.28 (syst.) MeV. The new state most likely corresponds to the J^P=3/2^+ companion of the Xi(b).Comment: Submitted to Physical Review Letter

    This is the pre-print version of the Published Article, which can be accessed from the link below - Copyright @ 2011 Springer VerlagMeasurements of inclusive W and Z boson production cross sections in pp collisions at sqrt(s)=7 TeV are presented, based on 2.9 inverse picobarns of data recorded by the CMS detector at the LHC. The measurements, performed in the electron and muon decay channels, are combined to give sigma(pp to WX) times B(W to muon or electron + neutrino) = 9.95 \pm 0.07(stat.) \pm 0.28(syst.) \pm 1.09(lumi.) nb and sigma(pp to ZX) times B(Z to oppositely charged muon or electron pairs) = 0.931 \pm 0.026(stat.) \pm 0.023(syst.) \pm 0.102(lumi.) nb. Theoretical predictions, calculated at the next-to-next-to-leading order in QCD using recent parton distribution functions, are in agreement with the measured cross sections. Ratios of cross sections, which incur an experimental systematic uncertainty of less than 4%, are also reported

    Commissioning and performance of the CMS silicon strip tracker with cosmic ray muons

    This is the Pre-print version of the Article. The official published version of the Paper can be accessed from the link below - Copyright @ 2010 IOPDuring autumn 2008, the Silicon Strip Tracker was operated with the full CMS experiment in a comprehensive test, in the presence of the 3.8 T magnetic field produced by the CMS superconducting solenoid. Cosmic ray muons were detected in the muon chambers and used to trigger the readout of all CMS sub-detectors. About 15 million events with a muon in the tracker were collected. The efficiency of hit and track reconstruction were measured to be higher than 99% and consistent with expectations from Monte Carlo simulation. This article details the commissioning and performance of the Silicon Strip Tracker with cosmic ray muons.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); Academy of Sciences and NICPB (Estonia); Academy of Finland, ME, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); PAEC (Pakistan); SCSR (Poland); FCT (Portugal); JINR (Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MST and MAE (Russia); MSTDS (Serbia); MICINN and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); TUBITAK and TAEK (Turkey); STFC (United Kingdom); DOE and NSF (USA)

    Measurement of dijet angular distributions and search for quark compositeness in pp collisions at √s=7TeV

    Get PDF
    Dijet angular distributions are measured over a wide range of dijet invariant masses in pp collisions at root s = 7 TeV, at the CERN LHC. The event sample, recorded with the CMS detector, corresponds to an integrated luminosity of 36 pb(-1). The data are found to be in good agreement with the predictions of perturbative QCD, and yield no evidence of quark compositeness. With a modified frequentist approach, a lower limit on the contact interaction scale for left-handed quarks of Lambda(+) = 5.6 TeV (Lambda(-) = 6.7 TeV) for destructive (constructive) interference is obtained at the 95% confidence level
