Nonlinear Model Predictive Control (NMPC) is a control strategy based on repeatedly solving an optimal control problem. In this paper we present a new MPC framework for the JModelica.org platform, developed specifically for use in NMPC schemes. The new framework utilizes the fact that the optimal control problem to be solved does not change between solutions, thus decreasing the computation time n
Distributed Generation (DG) installations have been increasing during the last years. Wind power and photovoltaics are two of the most common renewable energy sources for DG typically connected to the distribution network (DN) originally planned and built to supply loads. DG units connected to the DN impact the voltage where customers are connected. Network voltage is an important quality criterio
Background: The healthcare sector needs to deliver evidence-based care and be cost-effective. This can be monitored in part via a national quality registry containing individualized data concerning patient problems, medical interventions, outcomes of treatment, and patient-reported outcomes. With this aim, Web Rehab Sweden was launched in 1997 and has been available online since 2007. The aim of t
In this paper we present a new class of MAC protocols for wireless LANs based on sharing of transmission intentions. We develop an example protocol implementation based on distributed, co-operative scheduling of data frames. Sched- ules are non-binding, requiring minimal negotiation between nodes. The protocol is implemented on top of standard 802.11 so that backwards compatibility with legacy nod
Knowledge concerning how the built environment should be designed to allow accessibility for persons with different disablements is not sufficiently applied in building design and facilities management. Many of the difficulties in traditional paper based design to communicate and validate the use of a building can be overcome by the new possibilities that are offered by object oriented 3D based ca
22 april 2026 09:00 till 16:00 | Symposium Rethinking Mutations of Violence, Harm and Crime under Contemporary Market Logics Contemporary scholarship increasingly speaks of capitalism(s) rather than a singular capitalism. Platform economies, gig work, extractive markets, aestheticized consumer cultures, and criminalized market formations coexist and overlap, generating distinct configurations of p

The effect of lymph diversion on plasma apolipoprotein A-I levels was studied. In lymph fistula rats apolipoprotein A-I levels in plasma stayed constant in spite of a loss of an equivalent of one-half plasma pool of apolipoprotein A-I per day through the lymph fistula. This indicates that synthesis of apolipoprotein A-I increases or that catabolism of apolipoprotein A-I decreases in a compensatoryThe effect of lymph diversion on plasma apolipoprotein A-I levels was studied.

This paper presents the implementation of the probing control technique in an industrially relevant fed-batch fermentation process utilizing the microorganism Bacillus lichenifor has been done in pilot-scale experiments. The aim of the work is firstly to find out whether it is posuccessfully implement probing control in B. licheniformis fermentations. Secondly, it is to find out whing control can
The aim of this study was to investigate which preventive measures targeting mastitis are implemented in Swedish dairy herds with different housing and milking systems. Data were collected through a self-administered postal questionnaire sent to 898 dairy farmers, stratified by housing and milking system, in May 2011. The questionnaire contained general questions about the herd and the person resp
In this thesis, a stronger support for Model Predictive Control (MPC) in JModelica.org has been implemented. JModelica.org is an open-source software for simulation and optimization of systems described by Modelica models. MPC is an optimization-based control strategy where one formulates an Optimal Control Problem (OCP) to describe the aim of the controller. At discrete time points the state of t
