A two-gradient model is proposed for regulation and regeneration of the head end of hydra in terms of positional information. One gradient is set up by a diffusible substance made at the head end, which may be regarded as a positional signal, and the other is a more stable cellular parameter which is the positional value. The rule for head end formation is that the concentration of the diffusib...

The constantly rising fraction of industrial services reveals the structural economic change that is changing the manufacturing industry landscape. Manufacturing firms have more and more problems to find the appropriate information technology (IT) solution for planning and execution as they are confronted with the strategic challenge of reducing operating costs while at the same time meeting ev...

The capability maturity model integration (CMMI) has become one of the most preferred approaches to software process improvement (SPI). However, the amount of discontinued or delayed CMMIdriven SPI projects is considerable. In this paper we investigate the culture embedded in the CMMI and compare it with the cultures within an implementing organization in Scandinavia by utilising the competing ...

As information technologies evolve and demands of enterprises on larger data and integrated info services keep growing, the market of cloud services (CS) attracts many more players nowadays. However, the quality of the services may vary due to different service capabilities and a service often requires integration with other services, CS providers need a standard way in implementing and improvi...

Background: Maturity models for IT service such as CMMI-SVC and MR-MPS-SV requires identification of critical business process and definition of relevant metrics to support decision making, but there is no clear direction or strict suggestion about which should be those processes and metrics. Aims: We aim to identify adequate metrics to be used by organizations deploying IT service maturity mod...

This paper describes the use the Information Orientation (IO) Maturity Model as the basis of a MBA course-based project. The IO model explicitly draws the relationship between business performance and several information and technology management concepts. More importantly, the IO Model is accompanied by a specific method of gathering and analyzing data, and includes general recommendations on ...

Uncrewed aerial vehicles (UAVs) are continuously gaining popularity in a wide spectrum of applications, while their positioning and navigation most often relies on Global Navigation Satellite Systems (GNSS). However, numerous conditions practices require UAV operation GNSS-denied environments, including confined spaces, urban canyons, vegetated areas indoor places. For the purposes this study, ...

Background In the past decades, maturity models have become important tools to visualize progress in adopting processes and standards and to benchmark companies in their industry (Becker et al. 2009). Two of the best known and oldest maturity frameworks are the Capability Maturity Model (CMM; Paulk et al. 1993; Watts 1987) and its follow-up, Capability Maturity Model Integration (CMMi; CMMI Pro...

With industrial X-ray computed tomography (CT), even low-contrast defects in cast parts, such as cracks, pores and blowholes, can be localized and measured in three dimensions. Analysis of the defects can be performed using either multi-positional 2D cross-section planes or the 3D volume view. Additionally, 3D metrology with CT becomes more and more an effective tool for many tasks in productio...
