Controllers’ role in managerial sensemaking and information trust building in a business intelligence environment
2023
This study explores how an organization’s controllers (management accountants) give sense to the information provided by its business intelligence (BI) system, and thus shape the construction of information trust. A qualitative case study was conducted within a Finnish food manufacturing company, building on the notion of trust related to management accounting information and sensemaking theory. The study was informed through open-ended interviews and an examination of internal accounting and management reports. The authors found that the company used an integrated BI system that enabled the production of information in a timely and perceivably standardized manner. Controllers managed this …
Mobile platform for online processing of multimodal skin optical images: Using online Matlab server for processing remission, fluorescence and laser …
2015
Mobile platform for multimodal skin assessment has been developed. Different illumination sources allow switching between modalities. Diffuse reflectance spectral imaging is provided by five LEDs, fluorescence is excited by 405 nm LEDs, and laser speckle by 650 nm laser diode. Handheld, battery powered device includes all light sources and color camera with USB. The core of the system is Linux OS embedded microcontroller. USB, FTP and HTML with JavaScript combination is used to create standard image transfer and control interface. In combination with built in WiFi access point it allows online skin images storage and processing. It means that data processing algorithms are located and updat…
Stereoscopic Viewing Enhances Visually Induced Motion Sickness but Sound Does Not
2012
Optic flow in visual displays or virtual environments often induces motion sickness (MS). We conducted two studies to analyze the effects of stereopsis, background sound, and realism (video vs. simulation) on the severity of MS and related feelings of immersion and vection. In Experiment 1, 79 participants watched either a 15-min-long video clip taken during a real roller coaster ride, or a precise simulation of the same ride. Additionally, half of the participants watched the movie in 2D, and the other half in 3D. MS was measured using the Simulator Sickness Questionnaire (SSQ) and the Fast Motion Sickness Scale (FMS). Results showed a significant interaction for both variables, indicatin…
Spectral decomposition of RR-variability obtained by an open loop parametric model for the diagnosis of neuromediate syncope
2002
The role of the cardiovascular regulatory mechanism in patients with neuromediate syncope (NS) is poorly understood. The aim of this study was to accomplish continuous non-invasive analysis of the baroreflex mechanism in patients during a head-tip tilt-table test (HTT) using an open-loop autoregressive model with exogenous input. The model describes the causal dependence of the RR interval on the systolic arterial pressure (SAP) variability. Thus, RR variability results as the linear composition of SAP-dependent (Pdep) and SAP-independent parts of the RR power (P). Further, the model allows the estimation of the baroreflex gain using the modulus of the transfer function (G) from SAP to RR i…
Software/Hardware Issues in Modelling Insect Brain Architecture
2011
The concept of cognitive abilities is commonly associated to humans and animals like mammals, birds and others. Nevertheless, in the last years several research groups have intensified the studies on insects that posses a much simpler brain structure even if they are able to show interesting memory and learning capabilities. In this paper a survey on some key results obtained in a joint research activity among Engineers and Neurogeneticians is reported. They were focussed toward the design and implementation of a model of the insect brain inspired by the Drosophila melanogaster. Particular attention was paid to the main neural centers the Mushroom Bodies and the Central Complex. Moreover a …
Automašīnu un motociklu marku nosaukumi latviešu sarunvalodā
2022
Pēdējos gadsimtus kopā ar cilvēkiem veiksmīgi ir attīstījušies motorizēti transporta līdzekļi. Tā kā to nosaukumu variāciju ir ļoti daudz, saprotams, ka vēl vairāk ir arī to modeļu un paveidu. Bieži vien to nosaukumi un modeļi ir gari vai grūti izrunājami, tāpēc cilvēks tiem ir izdomājis dažādus sarunvalodas nosaukumus, respektīvi, iesaukas. Vai tiešām slinkums ir cēlonis, lai pārdēvētu automašīnu un motociklu, mopēdu ražotāju dotos, viņuprāt, labskanīgos nosaukumus? Kuilis, burbulis, cigārs vai, piemēram, vafele, banāns ir parasti, ikdienā bieži sastopami lietvārdi, tomēr šajā bakalaura darbā tiks pētītas šo un citu vārdu saikne ar automašīnu un motociklu modeļiem. Darba mērķis ¬¬– apkopot…
Recuperación muscular mediante la técnica fisioterápica del rodillo de espuma (foam roller)
2020
El músculo esa una estructura presente en la mayoría de animales que permite el movimiento. El daño muscular se solventa mediante la instauración de procesos de regeneración que se demoran en base al tipo de daño y la extensión del mismo. Existen múltiples estrategias para atajar el daño muscular pero el comportamiento a nivel metabólico de algunas de ellas no ha sido descrito. La hipótesis es que algunos de estas estrategias, concretamente en relación a la herramienta Foam Roller, o rodillo de espuma, podrían tener un efecto protector hacia el daño muscular. El Foam Roller, pues, podría atenuar el daño muscular y la inflamación acelerando los procesos curativos propios al organismo. La not…

Measurement and communication interfaces for distributed generation in smart grids
2013
The aim of this work is to perform a feasibility study on the measurement and communication strategies for the development of a new generation of interface devices for distributed generators and their integration on smart grids. The communication system can use one or more technologies, at the various levels, creating a low cost network infrastructure, in the framework of a SCADA (Supervisory Control and Data Acquisition) architecture. As regards the measurements, the attention is focused on the anti-islanding protection, based on a hybrid solution, which makes use of local measurements and communications with the grid, at both MV and LV level by employing the PLC technology. Some simulatio…
A control strategy based on intelligent algorithm (PSO) to perform electrical stimulation systems
2017
International audience; Adjusting stimulation parameters using control strategy based on reliable mathematical model that can predict perfectly the muscle response, may improve the efficiency of Functional Electrical Stimulation (FES) systems. In the present project, we investigate the PID control tuning based on the Particle Swarm Optimization (PSO) algorithm at the first time in neuro-muscular systems for updating automatically the stimulation pulse amplitude to track a desired force profiles. In the beginning, The PSO algorithm is used to identify unknown force model parameters. Next, optimal PID gains are found by the same intelligent algorithm to improve the control system. The obtaine…
