In order to develop new products, design engineers build digital product models leveraged by 3D-Computer-Aided-Design (CAD) systems. During design, they specify various aspects of the product: e.g., Which technical elements like wholes, pockets and materials the product consists of, or which tolerances have to be observed during production. This information is vital to stakeholders in subsequent processes...
Cloud computing has become one of the fastest growing segments of the IT industry. In the wake of this, cloud based Enterprise Resource Planning (ERP) systems have emerged as an alternative to traditional ERPs. The marketing of cloud based ERPs states that adoption require low upfront investments and can rapidly be deployed, as they are provided over the cloud. In this study we seek to unravel cloud...
Today, the proliferation of mobile devices coupled with the widespread availability of the Internet is opening up new service opportunities in numerous areas. However, developing mobile applications turns out to be very challenging. Two major plagues are heterogeneity and the need for dynamic adaptation happening at runtime. Dealing with these aspects leads to several problems and impasses. In this...
To understand the structure of a trade market, network analysts search for patterns in the link structure of the network with the help of so-called blockmodeling algorithms. We present a new combinatorial way to measure the deviation of a network from having a given pattern. We show that even though the computation of the deviation is NP-hard, it can be efficiently solved to optimality by a branch-and-cut...
The literature on cloud computing has been dominated by examples and issues from small to mid-size companies. This paper reports on a large scale cloud pilot project within the petrochemical industry, perhaps one of the biggest examples of cloud computing pushing the boundaries of what you can do with sensitive data. The study aimed to explore the challenges and practicalities of initiating and evaluating...
Discussion of an Engineering Master's Thesis of a novel rotating engine along with a case study on the benefits of relationship of Engineering Industry with academia.
In the paper we describe the NMF-based approach applied to the problem of determining an employee's access needs. The conducted research showed that the proposed NMF-based methods provide a useful analytical framework for processing and modeling employee's access needs data, and the obtained results demonstrate acceptable performance and provide descriptive representation model.
Cold-Start is one of the most difficult problems faced by web companies today in the domain of recommendation system. Cold-Start problem refers to predicting the behavior of a new user/item having no history. Common algorithms used to predict users behavior fail at addressing the cold-start problem because the algorithms are based on the user history with the company. But in this paper, we successfully...
For complex and popular software, project teams could receive a large number of bug reports. It is often tedious and costly to manually assign these bug reports to developers who have the expertise to fix the bugs. Many bug triage techniques have been proposed to automate this process. In this paper, we describe our study on applying conventional bug triage techniques to projects of different sizes...
Cloud computing or Infrastructure as a Service(IaaS) solutions such as Amazon's Elastic Computing Cloud(EC2) are very attractive for many commercial enterprises especially in today's limited or shrinking IT budgets environments. Cloud computing has been considered as a newest delivery model of enterprise's IT gradually. This paper is aimed at helping companies analyze several characteristics of multi-instance...
E-Business solutions are information systems mostly used by the Small and Medium Enterprises. To have a robust, scalable and elastic solution, some companies decide to use e-Business software as service that satisfy their needs and at the same time saves money. In addition to this, the infomatization of the company will be accelerated, and further development of the company will be processed. The...
Cloud computing delivers computational and communicational capabilities via the Internet. From processing and storing information and applications, to being able to access it from anywhere and at any time, cloud computing represents a breakthrough concerning how people and companies work and communicate through the Internet. In the last five years, cloud computing has a constant increase in its all...
In every distributed system there is a need for a real-time database when working with a large amount of data and when quick response from a service is expected on the client side. Cloud companies do not offer real-time databases, therefore, in this paper we present the architecture of a real time database in cloud environment, as well as reviews of other papers dealing with this topic, analyzing...
Software process lines (SPrL) is a trend in software companies for generating software processes adapted to specific project contexts, i.e., process tailoring. There are several strategies for process tailoring ranging from having a unique process always applied, to defining a specific process for each project, the former is inefficient while the latter is expensive. Two intermediate strategies used...
Building Information Modeling (BIM) is a relatively new technology emerging in the construction industry as it offers many advantages offers over typical construction drawings. However, new technology brings new problems and often uncertainty to an affected industry. Currently, the construction industry is experiencing much uncertainty as to how the BIM process works. There are very few industry standards,...
Cloud computing provides a means for developing economies to improve their global competitiveness. This is because it is a combination of infrastructure, technology innovation and technology readiness. Private organisations in the developing economy of context, believe there is a sizeable market to be served. The key challenge is to do this effectively at a price that is not only affordable but economically...
Data security is core concerns of hardware and software implementations. It is impacted not only by network architecture but also by access control mechanisms. In literature, there are several access control models such as the Mandatory Access Control (MAC), the Discretionary Access Control (DAC), the Role-Based Access Control (RBAC) and the latest one Usage Control Authorization, oBligation and Condition...
This paper concentrates on the problem of designing a powerful multi-agent negotiation model for E-commerce platform. In the multi-agent negotiation model, negotiations mean interactions between multiple agents with several different targets. The multi-agent negotiation model can be represented by seven elements, and the key component of a negotiation agent contains private data, knowledge base and...
Case studies have been used in different fields of university-level education already for decades. More recently, the advantages of using case studies have been realised by university-level computing educators, too. New approaches have been introduced in computing education — such as project-based learning, problem-based learning, situated learning or inquiry-based learning. Many of those approaches...
Recent years have seen the popularization of model based development (MBD) using models based on block diagrams. In many mechatronics systems, including automobile engine control and the brake control, a closed loop control is used to manage controls based on feedback data from control target objects. In order to develop a closed loop control using model base, a plant model that simulates the behavior...
