Validation of the MoSAIC-Driving Simulator – Investigating the impact of a human driver on cooperative driving behavior in an experimental simulation setup

The “Modular and Scalable Application Platform for ITS Components” (MoSAIC) offers the possibility to investigate cooperative driving behavior. MoSAIC consists of three driving-simulators linked together, allowing participants to drive within the same simulation. The goal of the study was to examine whether knowledge of another real driver would have an impact on cooperative driving behavior. Participants were forced to overtake a car on a motorway, while a third car was approaching from behind. Twenty people participated, of which ten were told that the approaching car was simulated by a computer and ten were told that another participant would be steering the car. However, the car was always controlled by one of the investigators. To examine cooperative driving behavior Time Headway, a measure of distance relative to speed, and the participants’ intentions were used to label a behavior as cooperative. Further the participants’ perceived risk and perceived cooperation were recorded. Significant group differences were discovered regarding the intentions, perceived risks and perceived cooperation.

Student Modeling: Supporting Personalized Instruction, from Problem Solving to Exploratory Open‐Ended Activities

The field of intelligent tutoring systems (ITSs) has successfully delivered techniques and applications to provide personalized coaching and feedback for problem solving in a variety of domains. The core of this personalized instruction is a student model: the ITS component in charge of assessing student traits and states relevant to tailor the tutorial interaction to specific student needs during problem solving. There are however, other educational activities that can help learners acquire the target skills and abilities at different stages of learning including, among others, exploring interactive simulations and playing educational games. This article describes research on creating student models that support personalization for these novel types of interactions, their unique challenges, and how AI and machine learning can help.

IT outsourcing and impacts in Thailand’s financial institutions

Information technology outsourcing (ITO) studies have been the focus of researchers for decades. One topic has been the factors and impact of ITO on organizations. Inconclusive findings about relationships between the levels of ITO and ITO success demands further exploration on this issue. In Thailand, the National Electronics and Computer Technology Center (NECTEC) reported that the financial and banking industry has the highest spending on computer services primarily by outsourcing the core banking and service management system. Nonetheless, research on ITO in Thailand’s financial industry has been limited. This study is among the first to empirically investigate the relationship between the levels of ITO, defined as the percentage of IT activities and components selected to be outsourced, and ITO success, defined by the benefits received from outsourcing in Thailand. A three-pronged approach is used in this study. It began with a comprehensive literature review. This was followed by in-depth expert interviews with representatives from financial institutions, academia, and outsource vendors, all of who offered opinions that shaped the development of the research model. A survey was then carried out with 428 IT personnel from the Thai financial sector. The results were analyzed using structural equation modeling (SEM). Contrary to previous researches, this study found that internal uncertainty and internal IT skills were two factors that do not affect the levels of ITO, while transaction costs and specific assets do. In addition, it was found that levels of ITO have impacts on ITO success. In a real world application, this study focuses on the different levels of ITO implementation among Thailand’s top five banks and their effects on ITO success. The findings increase researchers’ understanding regarding the factors that affect the levels of ITO and suggest that practitioners must consider the levels of ITO, in addition to other factors, when making ITO decisions. The framework can help practitioners optimize ITO practice for successful ITO outcomes.

Application validation versus infrastructure qualification

An often used method for application validation is the “black box” approach. The functionality or application is tested against predefined protocols and the results are compared to also predefined expected results. The underlying infrastructure is automatically validated in combination with the application.Audit Authorities and GMP regulations (Annex 11, GAMP) ask for a Qualified Infrastructure nowadays.An IT infrastructure is a complex system of IT components working together to enable the user to “use the applications” that run on it.To qualify an infrastructure the infrastructure has to be split up in parts; the “infrastructure components”. The process of building and changing these components has to follow strict Quality requirements.

Managing IT Infrastructure in Banks: Gap Analysis of UAE Banks

IT infrastructure is increasingly seen as an important factor affecting a banks competitive performance. IT infrastructure is the enabling base of shared IT capabilities that provide the foundation for other business systems. Banking IT infrastructure typically consists of IT components like common hardware, software, communication technology, databases, standards, tools etc. These provide the base for shared services between a large range of business application. IT infrastructure differs from business application in that it serves a shared and common enabling foundation for the future applications and services of all business units.

Cloud users no need to deploy the resources at their site because resources are available at the provider's side and they provide it and charged on usage basis. This paper focuses on the security of cloud computing considerations for Platform as a Service. Index Terms—Audit trial, cryptography, elasticity, hybrid cloud, private cloud, virtualization.

Replication capability of micro injection moulding process for polymeric parts manufacturing

Micro injection moulding process represents a key technology for realizing micro components and micro devices used in several fields: IT components, biomedical and medical products, automotive industry, telecommunication area and aerospace. The development of new micro parts is highly dependent on manufacturing systems that can reliably and economically produce micro components in large quantities. In this work, the authors investigate the process parameters on the overall quality of a miniaturised dog-bone-shaped specimen in order to determine the process constraints. The factors affecting parts aspects and mass are studied by experimentation designed using DoE methodology and then discussed. Two polymer materials (polyoxymethylene and liquid crystal polymer), particularly suitable for injection moulding applications due to their flowability and stability, are tested and evaluated in relation to the process replication capability. It has been found that the holding pressure and holding time for POM and holding pressure and injection velocity for LCP have the highest influence on achieving high part mass. Differently, melt temperature has the highest influence on minimising the process variability for both tested polymers. A further investigation has been carried out on the relationship between the holding pressure and the part mass and dimensions demonstrating the existence of a linear correlation between specimens mass and dimensions.

UV 레이저 미세 가공공정에서의 물 액적 렌즈 효과에 관한 연구

Recently UV laser micromachining processes is widely introduced to meet the needs of advanced components of IT, BT and ET industries. Due to the characteristics of non-contact and high-speed laser processing, UV laser micromachining is applied to manufacture very thin substrate such as polymer, metals and composite. These minimum line width obtained by UV laser micromachining is generally determined from laser wavelength, optical lens and its numerical aperture. In this paper we will show the lens effect of water droplet on the surface of workpiece to reduce the line width when UV laser light is irradiated and focused through the water droplet. Because of the refraction effect generated by the semi-spherical or spherical shape of water droplet, we can find smaller line width. And water droplet could not only protect thermal deformation, but also carry away burr around micro dent. Firstly fundamental theory of minimum line width was derived from relationship between the geometry of water droplet and laser light trace, and then experimental and simulation results will be finally compared to verify the effectiveness of water droplet lens effect of UV laser micromachining process.

Automatic data collection for enterprise architecture models

Enterprise Architecture (EA) is an approach used to provide decision support based on organization-wide models. The creation of such models is, however, cumbersome as multiple aspects of an organization need to be considered, making manual efforts time-consuming, and error prone. Thus, the EA approach would be significantly more promising if the data used when creating the models could be collected automatically--a topic not yet properly addressed by either academia or industry. This paper proposes network scanning for automatic data collection and uses an existing software tool for generating EA models (ArchiMate is employed as an example) based on the IT infrastructure of enterprises. While some manual effort is required to make the models fully useful to many practical scenarios (e.g., to detail the actual services provided by IT components), empirical results show that the methodology is accurate and (in its default state) require little effort to carry out.

Modeling Supply-Side Dynamics of IT Components, Products, and Infrastructure: An Empirical Analysis Using Vector Autoregression

Prior IS research on technological change has focused primarily on organizational information systems and technology innovation; however, there is a growing need to understand the dynamics of supply-side forces in the introduction of new technologies. In this paper we investigate how the interdependencies among information technology components, products, and infrastructure affect the release of new technologies. Going beyond the ad hoc heuristic approaches applied in previous studies, we empirically validate the existence of several patterns of supply-side technology relationships in the context of wireless networking. We use vector autoregression (VAR) to model the comovements of new component, product, and infrastructure introductions and provide evidence of strong Granger-causal interdependencies. We also demonstrate that substantial improvements in forecasting can be gained by incorporating these cross-level effects into models of technological change. This paper provides some of the first research that empirically demonstrates these cross-level effects and also provides an exposition of VAR methodology for both analysis and forecasting in IS research.

Everything-as-a-service platform for on-demand virtual enterprises

While constructing virtual enterprises, it is crucial to flexibly integrate heterogeneous business resources and processes of different business partners and make them collaborate dynamically. Keeping involved IT systems or components as autonomous and loose-coupled services, the "Everything as a Service" concept supports flexible integration of heterogeneous applications. We adopt this concept and analyze the challenges in virtual enterprise construction, then propose a service platform for on-demand virtual enterprises. The platform supports flexible integration of networked resources, and facilitates virtual enterprise construction with business process utility, trusted service composition and data service centric business collaborations. At the end of the paper, together with a case study, experimental evaluations in contexts of concurrent multi-users are presented, showing the effectiveness and performance of the platform.

S-D logic research directions and opportunities

The need for a systems approach to modeling and understanding service is now well established, (Barile 2009; Barile and Polese 2009; Golinelli 2010; Ng et.al., 2011a). Following the construction of Maglio et al (2009) we view a service-system as a network of agents and interactions that integrate resources for value cocreation. The context of value creation is intrinsic to the system design.and the adaptive, interactive actions of agents classifies the network as an ecosystem (Lusch et al, 2010). To date, several disciplines have broached the systems view of service and the engineering of service systems. Operations research applied to services began with a rather simplistic, macro view of resource integration in the form of Data Envelopment Analysis (DEA), introduced by Charnes, Cooper and Rhodes in 1978 (Charnes, Cooper et al. 1994, Banker, Charnes et al. 1984). Micro models of service systems have tended to study the systems’ IT components (Hsu 2009; Qiu 2009). Engineering, which has always been associated with “assembling pieces that work in specific ways” (Ottino, 2004) and “a process of precise composition to achieve a predictable purpose and function” (Fromm, 2010 p. 2) has contributed to greater scalability and purposeful control in service systems. However, the agents of the system usually are people whose activities may not be easily controlled by predictable processes and yet are critical aspects of the value-creating system (Ng et al, 2011b). There is need for a new combinative paradigm, such as third-generation activity theory in which two or more activity systems come into contact, to explore dialogue, exchanging perspectives of multiple actors, resulting in networks or groups of activity systems that are constantly interacting (Nardi 1996, Oliveros et al 2010, Marken 2006).

Availability measurement of grid services from the perspective of a scientific computing centre

The Karlsruhe Institute of Technology (KIT) is the merger of Forschungszentrum Karlsruhe and the Technical University Karlsruhe. The Steinbuch Centre for Computing (SCC) was one of the first new organizational units of KIT, combining the former Institute for Scientific Computing of Forschungszentrum Karlsruhe and the Computing Centre of the University. IT service management according to the worldwide de-facto-standard "IT Infrastructure Library (ITIL)" [1] was chosen by SCC as a strategic element to support the merging of the two existing computing centres located at a distance of about 10 km.The availability and reliability of IT services directly influence the customer satisfaction as well as the reputation of the service provider, and unscheduled loss of availability due to hardware or software failures may even result in severe consequences like data loss. Fault tolerant and error correcting design features are reducing the risk of IT component failures and help to improve the delivered availability. The ITIL process controlling the respective design is called Availability Management [1]. This paper discusses Availability Management regarding grid services delivered to WLCG and provides a few elementary guidelines for availability measurements and calculations of services consisting of arbitrary numbers of components.

ASSESSMENT SYSTEM FOR FEASIBILITY ANALYSIS OF NATIONAL R&D PROGRAMS: THE CASE OF KOREA

Most assessments for R&D programs are conducted for on-going or finished programs. In order to streamline national R&D programs, Korean government is making a challenging attempt. It enacted a law for ex ante evaluation for national R&D programs and KISTEP, which specializes in evaluation and planning for R&D programs, took charge of the important role. KISTEP created and developed guidelines for feasibility analysis on each category of R&D program. Many kinds of R&D programs, such as constructing facilities for nuclear fusion and developing IT components by organizing consortiums, were analyzed from the viewpoint of technology experts and policy makers. Various impacts expected to be made by R&D programs were crucial elements for the analysis too. This paper presents processes for the feasibility analysis of R&D programs, cruces of the processes, and how we have improved the assessment system. It also provides how the assessment system contributed to the innovation of national R&D programs.

WiSec 2011 demo

Cooperative Intelligent Transportation Systems must incorporate privacy-enhancing mechanisms to gain public acceptance. The PRECIOSA Privacy-enforcing Runtime Architecture (PeRA) provides a data-centric protection chain, which ensures that ITS components process data according to attached user-defined privacy policies. PeRA instances constitute a distributed privacy middleware that evaluates privacy policies to mediate data access by applications. An integrity protection layer creates a distributed policy enforcement perimeter between ITS nodes to prevent circumvention of policies. The PeRA has been implemented as a proof-of-concept prototype.

On energy efficiency for enterprise and data center networks

In recent years, there has been intense focus on increasing the energy efficiency of IT infrastructure. We advocate the need to consider energy consumption holistically over the entire lifetime of these devices. Life cycle energy considerations include a number of factors, of which operational energy consumption is just one. Of all the IT components, networks have received relatively little attention when it comes to energy efficient operation, and even that has been too focused on operational power consumption. In this article, we describe the challenges relating to life cycle energy management of network devices, present a sustainability analysis of these devices, and develop techniques to significantly reduce network operational power. A distinguishing feature of our work is that it is applicable to legacy devices, and as such can be deployed now, as opposed to waiting for new standards and products to be developed.
