1. 1. Stochastic Modeling and Management of an Emergency Call Center : A Case Study at the Swedish Emergency CallCenter Provider, SOS Alarm Sverige AB

   Författare :Klas Gustavsson; Leif Olsson; Panagiotis Papapetrou; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Call Center Management; Burst Modeling; Stochastic Resources; Skills-Based Routing; Discrete-Event-Simulation;

   Sammanfattning : A key task of managing an inbound call center is in estimating its performance and consequently plan its capacity, which can be considered a complex task since several system variables are stochastic. These issues are highly crucial for certain time-sensitive services, such as emergency call services. LÄS MER

3. 2. Modeling receptor induced signaling in MSNs : Interaction between molecules involved in striatal synaptic plasticity

   Författare :Anu G. Nair; Jeanette Hellgren Kotaleski; Omar Gutierrez-Arenas; Upinder S. Bhalla; Pierre Vincent; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Striatal synaptic plasticity; LTP; Dopamine; Acetylcholine; Synergy; Medium spiny neurons; MSNs;

   Sammanfattning : Basal Ganglia are evolutionarily conserved brain nuclei involved in several physiologically important animal behaviors like motor control and reward learning. Striatum, which is the input nuclei of basal ganglia, integrates inputs from several neurons, like cortical and thalamic glutamatergic input and local GABAergic inputs. LÄS MER

4. 3. Microphysical Conditioning of Gamma-Ray Burst Shocks

   Författare :Jacob Trier Frederiksen; Claes Fransson; Åke Nordlund; Mikhail V. Medvedev; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic fields; particle acceleration; plasma instabilities; gamma-ray bursts; collisionless shocks; relativistic outflows; Astronomy and astrophysics; Astronomi och astrofysik; Astronomy; astronomi;

   Sammanfattning : Gamma-Ray Bursts (GRBs) are believed to be connected with either collapse of massive stars or – in some cases – coalescing neutron stars, both of which cause extreme relativistic explosions observable from the entire Universe. GRBs produce rapid flashes of high energy radiation, extending up to 2MeV in photon energies: as much energy per photon as the rest mass of 4 electrons. LÄS MER

5. 4. Modeling of bursting mechanisms and coordination in a spinal central pattern generator

   Författare :Jeanette Hellgren Kotaleski; KTH; []
   Nyckelord :adaptation; central pattern generator; computer simulation; inter segmental coordination; lamprey; locomotion; neural network; rhythmogenesis; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Mechanisms underlying lotal bursting as well as coordinationbetween different levels of a spinal CPG generating locomotionhave been investigated using computer simulations. A"primitive" jawless vertebrate, the lamprey, is used a.s aprototype model. LÄS MER

7. 5. Neural mechanisms for the control of posture, locomotion and steering : a behavioral, electrophysiological and modeling study in lamprey

   Författare :Patriq Fagerstedt; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :reticulospinal; vestibular system; spinal cord; central pattern generator; reciprocal inhibition; fictive locomotion; fictive turning; electron microscopy; computer simulation; lamprey; dorsal fin;

   Sammanfattning : When animals move around interacting with the environment, the nervous system has to solve several tasks simultaneously in order to produce and control the movements - notably propulsion, posture, balance, and associated movements. Basic motor tasks are controlled by neuronal networks organized into central pattern generators (CPGs) and reflexes, located in the spinal cord and brainstem. LÄS MER
