There is a gap in the theory of acquisition, little investigation have been made on the acquired firm within the acquisition process and in service industries. Because of the lack of research in this area, this research is focusing on acquisition theory and how it positions to the acquired firm rather than the firm making the acquisition. Therefore a need to investigate the acquisition theory on acquired firms on SME: s in the IT-service industry is interesting. To do so, three case studies have been made on three firms that have been acquired. The empirical results from the case studies have shown how the relationship between the parent company and the subsidiary has differences. The company culture and the relationship to the parent firm differs if the parent firm is foreign or not; and if the acquisition process is mutual between two firms rather than a market extension acquisition. By analyzing the data of this research the study show that the previous theories of acquisition are adaptable to implement on firms that have been acquired on SME:s in the IT-service industry.

This thesis considers how different groups of Spanish speakers (monolinguals, early bilinguals and late bilinguals) organize and limit grammatical optionality related to the placement of Spanish pronominal clitics with many complex infinitival constructions (Spanish clitic-climbing). In examining empirical work on the process and outcome of early and late dual language exposure and how early and late bilinguals acquire and limit grammatical optionality, this study will contribute to our understanding of 1) the nature of language-related cognition at different ages; 2) the systematic nature of bilingual language behaviour in child and adults (transfer, cross-language influence, etc.); 3) the cognitive and contextual factors associated with age of exposure to bilingualism to explain bilingual language behaviour; and 4) the importance of incorporating a clear model of language variation (language-internally and cross-linguistically) into a formal model of (bilingual) language. The empirical study conducted here tested how highly proficient heritage speakers (HS) of Spanish (native speakers of Spanish and Spanish-English bilinguals) deal with the optionality of clitic-climbing structures compared to monolingual speakers (native speakers) and highly proficient adult L2 speakers of Spanish (Spanish-English bilinguals). Forty participants completed a picture elicitation task testing a lexical limitation of the optionality, and an acceptability-preference task testing the speakers’ judgments on structural, semantic and lexical limitations of the optionality. Results show that all groups of speakers exhibited knowledge of syntactic constraints associated with pronominal placement in Spanish (optional clitic-climbing) infinitival sentences. All groups also performed similarly in exhibiting sensitivity to non-categorical factors that have been shown to guide the preferences of monolingual Spanish speakers. However, in the production task, the heritage speakers significantly outperformed the monolingual and non-native speakers of Spanish in their use of the Spanish-specific variant (proclisis). I explain these results through both cognitive and contextual factors related to age of exposure to bilingualism, and I discuss how the production results may underestimate a monolingual-bilingual difference for this optional domain.

This thesis investigates the suitability of global navigation satellite system (GNSS) signals for cellular phone location. The requirement is to determine and report the location of a phone during an emergency call.<p> The thesis analyzes acquisition and tracking techniques suitable for very weak signals as received by a cellular phone indoors. The L1 and L5 signals from GPS satellites and the L1 signal from Galileo satellites are considered. It is shown that long integration times and coherent integration are required for the weakest expected signals. Long coherent integration times require a precise knowledge of the Doppler shift due to the range rate of the satellite. The tolerance to Doppler shift can be increased by using FFTs in the analysis of the data. Non-coherent averaging techniques improve the Doppler tolerance but compared to coherent averaging, the loss of signal to noise ratio is too large for the weakest signals.<p> Coherent averaging of the GPS L1 signal requires data removal that can be accomplished with assistance from the cellular network. The GPS L5 and Galileo L1 signals include a data-less or pilot channel. The GPS L5 pilot channel includes a 20 bit Neuman Hoffman code with a bit period of 1 ms. This code has to be acquired or removed before coherent averaging. Similarly the Galileo pilot channel includes a 25 bit short code.<p> Once code acquisition has been accomplished, it is necessary to track the signals from at least four satellites for long enough to compute a position estimate. A discussion of tracking techniques is included to show the signal to noise ratio limitations for adequate tracking accuracy.<p> The results show that GNSS signals are suitable for cellular phone location in a large number of situations. Increased receiver sensitivity would permit location in additional situations. In rural situations GNSS may be the only available option.

The report is focused on the implementation of a data acquisition system that will be used for measuring different parameters which are needed in solar panel behavior analysis. To accomplish the DAQ system a DAQ board has been designed and implemented. This DAQ board acquires measured climatic parameters that affect the PV module behavior and voltage and current of a PV module. The DAQ board may take measurements of multiple analog and digital signals that come from various sensors including solar radiation, temperature, wind sensors and other measurement devices. The DAQ board may also output analog signals for controlling other devices. The DAQ board is the basic part of the DAQ system and several of them can be connected via a single communication bus (RS485). A unique slave ID can be assigned to each DAQ board on the communication bus, which allows the control of all boards via a GUI application installed on a master computer. Therefore, the DAQ system can be used for monitoring a PV module installation as well as logging the measured data in a data storage server. This report outlines the details of the DAQ system design which are helpful in utilizing or upgrading this system. These details also include programming of DAQ board and implementation of MODBUS communication protocol within the DAQ system.

Des études antérieures ont démontré que les contraintes prosodiques influencent les premières productions des enfants et en particulier, leurs productions des déterminants. Une recherche de Tremblay et Demuth (2007) démontre que, pour une langue avec un pied iambique comme le français (faible/fort), les premiers déterminants sont rendus licites par le patron accentuel du mot qui suit. Après avoir analysé les productions spontanées de deux enfants francophones de leur 17e à leur 29e mois, les auteurs proposent que les premiers déterminants sont des clitiques internes au pied prosodique, c'est-à-dire omis avec les mots bi-et trisyllabiques; les déterminants produits par la suite sont des clitiques internes au mot prosodique et finalement, les clitiques s'attachent directement au syntagme phonologique. Cette recherche de Tremblay et Demuth soulève la question suivante: Qu'arrive-t-il lorsqu'un adjectif est placé entre le déterminant et le nom? Comment cela affecte-t-il la production du déterminant? Dans la présente étude, nous tentons de répondre à cette question en étudiant la production du déterminant lors d'une tâche de répétition de 54 phrases. Nous avons demandé à 9 enfants québécois francophones âgés entre 22 et 31 mois de répéter des phrases de 4 ou 5 mots de la forme « Pronom V SN ». La forme du SN variait en fonction de trois conditions: déterminant + nom monosyllabique, déterminant + adjectif + nom monosyllabique, déterminant + nom bisyllabique. Notre hypothèse était que les déterminants qui ne peuvent s'insérer dans un pied prosodique iambique sont omis. Les deux premières conditions avaient pour objectif de répliquer les résultats obtenus par Tremblay et Demuth. Dans la condition avec un nom monosyllabique, nous avions prédit que le déterminant devrait être produit puisqu'il peut être syllabifié avec le nom. Dans la condition bisyllabique et dans la condition monosyllabique avec adjectif, les déterminants devraient être omis puisque les enfants, selon notre hypothèse, sont restreints au pied prosodique. Le taux d'omission du déterminant devrait être le même pour la condition bisyllabique et pour la condition avec adjectif. Tel qu'attendu, les résultats ont démontré qu'il y avait plus d'omissions du déterminant dans la condition avec un mot monosyllabique que dans les deux autres conditions, mais, contrairement à ce que nous avions prédit, il y a eu plus d'omissions du déterminant dans la condition avec un adjectif que dans la condition avec un nom bisyllabique. Ces résultats s'expliquent par le fait que les enfants ne sont pas limités à la production du pied iambique et ils s'expliquent également par une évolution dans les étapes d'acquisition des différents niveaux de la structure prosodique. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Acquisition, Prosodie, Phonologie, Enfant.

The relative economic efficiency of acquisitions as a means of restructuring financially distressed firms is investigated. Yearly accounting and daily stock price data are extracted for the period between 1979 and 1998 on firms entering financial distress The behaviour and performance of these firms were traced for a five year period following their entry into distress or until their shares were no longer trading. These collected data forms the basis for analyzing the returns acquired from investing in potential takeover targets. Survival analysis is used to analyze the hazard rate for both the acquisition and bankruptcy of distressed firms. The results of the analysis indicate that the ZSCORE, a predictor of the probability of failure, and SPCSRM, the rating by Standard and Poor's, can be used as financial indicators in the screening mechanisms for financially distressed firms. A multinomial-logit acquisition model is used to predict three outcomes of financially distressed firms: survival, acquisition and failure. This model is tested using two methods by simulating the probability of acquisition. The first uses to compare the predicted versus the actual corporate events to maximize the predicted acquisition event. The second uses to compute abnormal return to maximize portfolio return over a given time period, continual on the ZSCORE, probability of acquisition, and the length of holding period. The predictive model of the acquisition probability is applied as a stock entry rule in a buy-sell system. The success of the model will serve two purposes. One is to predict the economic value of acquisition. The other is to provide successful strategies for investing in stocks.
