A Potts feedback neural network approach for finding good solutions to resource allocation problems with a nonfixed topology is presented. As a target application, the airline crew scheduling problem is chosen. The topological complication is handled by means of a propagator defined in terms of Potts neurons. The approach is tested on artificial random problems tuned to resemble real-world conditi
Access to safe drinking water and sanitation is essential for both individual and population health as well as for quality of life and dignity. The UN Sustainable Development Goals (SDGs) require nations to ensure adequate water supply and sanitation for all. For Kazakhstan, this means that rural areas will need a much stronger attention as they have been rather neglected in efforts to comply with
Spin relaxation theory and nuclear magnetic resonance spectroscopy in amphiphilic liquid crystals are presented. Group theory is used to determine the information content and the orientation dependence in spin relaxation experiments, and to investigate the combined effect of crystal and local symmetries and the effect of symmetry on multiple timescales. From lineshapes of a deuterated decanol and
The use of this material under current use conditions is supported by the existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization potential, as well as, environmental safety. Repeated dose toxicity was determined to have the most conservative systemic exp
Due to anatomical restrictions, the inflammatory response to intracerebral bacterial infections exposes swollen brain tissues to pressure and ischemia, resulting in life-threatening damage. Rapid diagnosis and immediate empirical antibiotic therapy is highly important. However, diagnosing meningitis in patients after neurosurgery is complicated, due to brain tissue damage and changes in cerebrospi

Popular Abstract in Swedish Ugandas regering har strävat efter att skapa en behovsbaserad och kostnadseffektiv hälso- och sjukvård på två olika sätt: hälsosektorn har decentraliserats för att öka ansvarstagande och medverkan på lägre nivåer. Kompetens har byggts upp för att kunna utveckla en nationell policy, och därigenom kunna bedöma sjukvårdsbehov och för att göra kostnadseffektiva prioriteringThe Ugandan Government has aimed at creating a needs-based and cost-effective health care system. The means to carry out this aim have been 1) a decentralization of the health sector in order to increase lower-level responsibility, accountability, and participation, and 2) a strong national policy formulation capacity, facilitating needs assessment and cost-effective prioritization. Aim The aim
Notice taken towards the position of philanthropy in sub-Saharan Africa has increased in the lastdecade. Increasing amounts of private wealth, charity and philanthropy initiatives are changing the landscape earlier characterised by traditional forms of philanthropy that have been practised between people and communities. This study explored the central conversation around philanthropy in sub-Sahar
Following the outbreak of the Syrian civil war in 2011 and the subsequent collapse of the national oil infrastructure, small-scale, makeshift oil refineries emerged in al-Hasakah Governorate as a new form of infrastructure to ensure local access to oil products. While reports have documented these developments and their widespread negative consequences for both humans and the environment, previous
X-ray absorption spectroscopy (XAS) is performed to study changes in the electronic structures of colossal magnetoresistance (CMR) and charged ordered (CO) La1-x Ca x MnO3 manganites with respect to temperature. The pre-edge features in O and Mn K-edge XAS spectra, which are highly sensitive to the local distortion of MnO6 octahedral, exhibit contrasting temperature dependence between CMR and CO s
We consider a stochastic version of the proximal point algorithm for convex optimization problems posed on a Hilbert space. A typical application of this is supervised learning. While the method is not new, it has not been extensively analyzed in this form. Indeed, most related results are confined to the finite-dimensional setting, where error bounds could depend on the dimension of the space. On
The homogenization of the Maxwell equations at fixed frequency is addressed in this paper. The bulk (homogenized) electric and magnetic properties of a material with a periodic microstructure are found from the solution of a local problem on the unit cell by suitable averages. The material can be anisotropic, and satisfies a coercivity condition. The exciting field is generated by an incident field fr
The local density theory is developed by Hohenberg, Kohn and Sham is extended to the spin polarized case. A spin dependent one- electron potential pertinent to ground state properties is obtained from calculations of the total energy per electron made with a `bubble' (or random phase) type of dielectric function. The potential is found to be well represented by an analytic expression corresponding
Using panel micro data fro\m Community Innovation Survey in the Czech Republic, Norway and the UK, we estimate dynamic random effects models, in which the innovation output of firms is the function of their cooperative behaviour and other observed characteristics, while accounting for unobserved heterogeneity. The results indicate that the capacity of firms to build on external domestic linkages i
We show how probabilistic numerics can be used to convert an initial value problem into a Gauss–Markov process parametrised by the dynamics of the initial value problem. Consequently, the often difficult problem of parameter estimation in ordinary differential equations is reduced to hyper-parameter estimation in Gauss–Markov regression, which tends to be considerably easier. The method’s relation
Popular Abstract in English If you wonder about the journey of goods and services before they reach you and the effects that journey has on the natural environment and the society, this dissertation is for you. In order to deliver goods and services from raw materials to you, the customer/consumer, several organizations and individuals interact with each other. They source the materials, manufactuTo develop sustainable supply chains in a way that their negative environmental and social effects are minimized, shortand long-term targets should be set. The transformation of supply chains towards these targets calls for the development of innovative strategies and the need to continuously identify, classify, and tackle the challenges that can hinder the execution of such strategies.
