Abstract
For a company it is important to improve resource and eco-efficiency in order to save money, the environment and to improve the company's image. We present a new approach combining Multi-layer Stream Mapping (MSM) and a Business Process Based Monitoring and Control Framework to monitor relevant process variables and use the values as an input for MSM to reduce waste and costs. This combination supports the decision making process and allows to identify major inefficiencies and provides means for more sustainability.

Abstract
This paper presents the evaluation methods and techniques applied to the serious game developed within the VirtualSign project as well as the results achieved through those methods. VirtualSign is a Portuguese sign language bi-directional translator with three main components. The components are a gesture to text translator, a text to gesture translator and a serious game. The serious game aims to make the process of learning sign language easier and enjoyable using the VirtualSign bi-directional translator. The method used to evaluate the VirtualSign was the Quantitative Evaluation Framework (QEF). The translator undertakes a rigid validation process by both sign language experts and the deaf community. The evaluation process was also supported by questionnaires. The precision of the translator has a direct impact on the game performance. To evaluate the precision of the automatic translator we have used QEF and 10-fold cross validation to estimate the accuracy of the translator. The experimental results show a precision above 90%. In the identification of the Portuguese Sign Language terms As for the game the quality rate is 88% based on the QEF evaluation.

Abstract
The logical depth with significance b of a string x is the shortest running time of a program for x that can be compressed by at most b bits. Another definition is based on algorithmic probability. We give a simple new proof for the known relation between the two definitions. We also prove the following: Given a string we can consider the maximal decrease in logical depth when the significance parameter increases by 1. There exists a sequence of strings of lengths n = 1,2,..., such that this maximal decrease as a function of n rises faster than any computable function but not as fast as the Busy Beaver function. This holds also for the computation times of the shortest programs of these strings.

Abstract
The usage of application-specific hardware based on Field-Programmable Gate Arrays (FPGA) has proven its benefits. Current system-on-chips, which contain FPGA fabric, supporting dynamic partial reconfiguration, enable a dynamic hardware acceleration for hardware/software co-designs. With the trend to consolidate multiple computing systems into a single system, applications with mixed criticalities can come into conflict. With our approach, we are exploring the possibility to utilize dedicated hardware for the system management and benefit from possible parallelization of applications and system management tasks.

Abstract
This paper proposes a conceptual model that analyses the factors influencing the export performance of small and medium-sized enterprises (SMEs) and integrates international entrepreneurship theory and international strategies. Rooted in an extensive bibliography that provides the basis for key constructs, the proposed model brings together the fundamentals of SMEs' internationalisation processes that influence these enterprises' export performance. The model highlights three important factors: industry-, environment- and firm-related aspects affecting firms' entrepreneurial orientation. The model contributes to a better understanding of the key factors affecting the export performance of SMEs, providing a simple structure that can be strategically used by entrepreneurs when launching their firms into international markets. The model complements previous approaches but offers a more integrative approach based on research that ventures further into a little explored area of the literature on internationalisation theories.
