When the orthogonal space-time block code (STBC), or the Alamouti code, is applied on a multiple-input multiple-output (MIMO) communications system, the optimum reception can be achieved by a simple signal decoupling at the receiver. The performance, however, deteriorates significantly in presence of co-channel interference (CCI) from other users. In this paper, such CCI problem is overcome by applying the independent component analysis (ICA), a blind source separation algorithm. This is based on the fact that, if the transmission data from every transmit antenna are mutually independent, they can be effectively separated at the receiver with the principle of the blind source separation. Then equivalently, the CCI is suppressed. Although they are not required by the ICA algorithm itself, a small number of training data are necessary to eliminate the phase and order ambiguities at the ICA outputs, leading to a semi-blind approach. Numerical simulation is also shown to verify the proposed ICA approach in the multiuser MIMO system.

This research paper has been prepared by Bachelor students from Dalarna University in Borlänge. The project is centered on a case study of ICA – Kvantum and its brand awareness among customers. The purpose of this study is to find out that which measures can help ICA-Kvantum to create brand awareness among its current and potential customers by looking in to the importance of information of its offerings and use of effective communication tools to convey this information. Further, to recommend them what they need to do, to increase brand awareness among their customers with the help of managerial implications. The research question was formulated as what actions could be seen effective for ICA-Kvantum to maintain or improve brand awareness among its current and potential customers.The project was created with the help of theoretical concepts of brand awareness, brand loyalty, perceived quality, consumer decision model, integrated marketing communication approach and strategic planning process. These theories were applied in this thesis in order to find out the most effective communication measures to maintain or improve brand awareness among current and potential customers of ICA-Kvantum.The primary and secondary data was collected. Primary data was gathered through the survey among ICA-Kvantum customers in the front of the store in Borlänge. The personal interview with manager was conducted in the office of ICA-Kvantum store located in Borlänge. Secondary data was gathered from textbooks, academic journals, theses and websites.The empirical findings have been presented in detail and then analyzed with the help of theoretical concepts. The analysis and further results from survey and interview focused on importance of information, marketing communication tools, brand awareness and loyalty, perceived quality and implementation of strategic planning process. Moreover, the main weaknesses and strengths of ICA-Kvantun have been evaluated. The conclusion including short summary of analysis and its results have been provided at the end. Each weakness of issues related to brand awareness i.e. importance of information, effectiveness of marketing communication tools and strengths and weaknesses of ICA-Kvantum discussed in the paper, has been pointed out along with solutions and managerial implications.

Syftet med examensarbetet var att med utgångspunkt i ett konkret exempel, beskriva hur företag kan organisera verksamheten för att ta till vara på de anställdas outnyttjade kreativitet. Materialet i examensarbetet kan mycket väl tillämpas och användas i andra organisationer än den studerade organisationen Ica DE Borlänge. Dock bör beaktande tas till den specifika kontexten som föreligger vid implementeringen av materialet. Med stöd av den teoretiska referensramen visar resultaten av analysen ett behov av en ny organisationsstruktur med tydliga roller och nya belöningssystem. Den studerade organisationen är en lärande organisation där ett medarbetarengagemang söker främjas. Genom en ny organisationsstruktur med tydliga roller ökar detta medarbetarengagemanget och fler genomförda förbättringar genomförs snabbare, vilket bidrar till att de anställdas outnyttjade kreativitet tillvaratas på ett framgångsrikt sätt. De nya belöningssystemen flyttar fokus till medarbetarengagemanget och förbättringsarbetet, vilket främjar ett genomsyrande Lean-tänkande i organisationen. Belöningssystemen skapar även jämnare produktionsflöden som höjer arbetssäkerheten, ökar produktionskvalitén, minimerar stress samt skapar goda förutsättningar för att beräkna personalbemanningen. Kvalitativa metoder har använts för datainsamlingen. Dessa utfördes genom en förstudie och en fallstudie. Fallstudien bestod utav bakgrundsintervjuer, en intervjustudie samt en observation. Det empiriska materialet visar att organisationen arbetar med ett omfattande förbättringsarbete i alla organisatoriska nivåer. Både chefer och medarbetare har viljan och ambitionen att få till ett framgångsrikt förbättringsarbete, men trots flera års arbete med Lean efterfrågas ändå mer tid, bättre organisationsstruktur samt en sambandskoordinatör med specialistkompetens som driver förbättringsarbetet framåt. Empirin ger en viss indikation på att förbättringsverksamheten har anpassats och organiserats till den befintliga organisationsstrukturen. Förbättringsarbetet torde bli mer framgångsrikt om verksamheten anpassas och organiseras utefter de anställdas outnyttjade kreativitet istället. I summering av slutsatsen åskådliggörs två centrala variabler som kan bidra till långsiktiga framgångar i arbetet med att tillvarata de anställdas outnyttjade kreativitet. En ny organisationsstruktur med tydliga roller som fokuserar på förbättringsarbetet samt nya belöningssystem för inlämnade förbättringsförslag, skulle vara av stor betydelse för ett långsiktigt medarbetarengagemang i en framgångsrik organisation.

El objetivo de ese trabajo de finalización de curso es dar a conocer el trabajo de la Institución de Incentivo à Criança e ao Adolescente (ICA) de la ciudad de Mogi Mirim, São Paulo, através de un gran reportaje para revista especializada en educación. El producto también se expone en la arte-educación, la herramienta principal de trabajo de la institución, y lo que es Tercer Sector, que el ICA se inserta. Através de entrevistas, encuestas y la experiencia, se buscó poner en práctica las técnicas periodistas que se aprendió a lo largo del curso de graduación y llevar al lector un informe claro y completo, lo que contribuye a la comprensión de los temas tratados

Independent component analysis (ICA) or seed based approaches (SBA) in functional magnetic resonance imaging blood oxygenation level dependent (BOLD) data became widely applied tools to identify functionally connected, large scale brain networks. Differences between task conditions as well as specific alterations of the networks in patients as compared to healthy controls were reported. However, BOLD lacks the possibility of quantifying absolute network metabolic activity, which is of particular interest in the case of pathological alterations. In contrast, arterial spin labeling (ASL) techniques allow quantifying absolute cerebral blood flow (CBF) in rest and in task-related conditions. In this study, we explored the ability of identifying networks in ASL data using ICA and to quantify network activity in terms of absolute CBF values. Moreover, we compared the results to SBA and performed a test-retest analysis. Twelve healthy young subjects performed a fingertapping block-design experiment. During the task pseudo-continuous ASL was measured. After CBF quantification the individual datasets were concatenated and subjected to the ICA algorithm. ICA proved capable to identify the somato-motor and the default mode network. Moreover, absolute network CBF within the separate networks during either condition could be quantified. We could demonstrate that using ICA and SBA functional connectivity analysis is feasible and robust in ASL-CBF data. CBF functional connectivity is a novel approach that opens a new strategy to evaluate differences of network activity in terms of absolute network CBF and thus allows quantifying inter-individual differences in the resting state and task-related activations and deactivations.
