The brand development strategy of the ATV/UTV industry - using Y company as a case study

Lin, Shih-Chang 28 July 2010 (has links)
This thesis focuses on how to elevate the Taiwanese motorcycle industry through a strategy based on successful branding. One of the items discussed is how most Taiwanese manufacturers produce mainly small sized motorcycles that are facing increasing competition and slower sales due to a saturated domestic market. Using the SWOT analysis and taking advantage of Taiwan¡¦s capabilities in R&D and production, entering the ATV/UTV niche market is the best path to long term profitability. ¡]1¡^A thorough analysis of the world¡¦s ATV/UTV market, sales volume by country, brand and model, is the path that should be taken by all the Taiwanese manufacturers. ¡]2¡^A successful branding strategy requires the following: 1¡DOne of the key factors is to start with clear product positioning and have differentiating and innovative products. 2¡DSuccessful sales channel development 3¡DCommunicate the brand value with the consumer-the customer is always right. A branding company is not in the business of just selling products (where the performance, features, and quality must be right), but price and after service also play an equally important role. A brand will not be fully accepted by the consumer until the brand has achieved full customer satisfaction by taking care of all the items above. 4¡DAn analysis on Taiwan¡¦s branded companies and interviews with the professionals who have helped create such brands are the key validation processes.

Design of Suspension and Steering Mechanisms for All Terrain Vehicles

Wang, Sieng-Siang 24 August 2006 (has links)
All-terrain vehicle(ATV) is very popular in Europe and North America because of its excellent riding performance. The Design of suspension and steering mechanism is one of the most important parts in ATV design, because it is much related to the riding performance of ATVs. Therefore, this research focuses on investigating the design of suspension and steering mechanism for ATVs. There are two main objectives to be achieved in this research. One is to build the analysis theory, and the other is to develop a systematic design process of suspension and steering mechanism for ATVs. Firstly, we survey papers about suspension and steering mechanism to find its basic functions and properties. Secondly, we use engineering design method to classify the design requirements and frame the design process. Thirdly, we list new suspension and steering mechanisms by applying the creative mechanism design procedure, then separate the new mechanisms separate into two types. One type is suitable only for back-wheel drive vehicles, and the other type is suitable for back-wheel drive and four-wheel drive vehicles. Finally, we complete the kinematic design of the type1.1(double-wishbone) and type8.3(new mechanism) suspension and steering mechanisms based on the Genetic algorithm (GA), and we can obtain the better mechanism dimensions than Yamaha 660 and 450 ATV.

Taiwan Motorcycle Industry of Competitive Strategy - A Case Study of All Terrain Vehicle industry.

Wu, Chun-Chieh 26 June 2007 (has links)
Abstract The main core of this study is ATV industry in Taiwan to look for new development field. Basic on this point of view and Taiwan experience, this study analyses the ATV industry and market strategy for Taiwan manufacturer. From understanding the ATV industry further to analyses the currently development situation in Europe, American and Japanese market and the operating situation of main manufacturer assist with SOWT and Five Forces Framework analysis to help the manufacturer have more competition opportunity and offer the future development suggestion. The conclusion is as below: 1. The competition strategy of Taiwan ATV industry exist competition price and non-competition price strategy. The manufacturer must be in leading position of the new vehicles development in order to be the leader in this market. 2. As the market grow, the manufacturer must take difference strategy to win the customer confidence, and the quick changing of the out looking will be the key trend of the market. So to own the tooling development and production ability will make the products in great use. 3. The ATVs are mostly used on risky environments so the production liability are more important than others feature. In some countries, the end users form ATV club and in this way " brand reputation" is going to be important part. 4. The new manufacturer of ATV must take price strategy to win one place in the market. 5. The completive price is a short - term strategy, only the products difference can make the profit in long - term. 6. The future completion of Taiwan ATV industry decides on new technology and brand value increasing, not on price. Keyword: ATV, competition strategy , All Terrain Vehicle

Modelling and Dynamic Simulation of Tracked Forwarder in Adams ATV Module / Modellering och dynamisk simulering av bandskotare i Adams ATV

Ramachandran, Praveen January 2015 (has links)
Swedish forest industry is relying on the cut-to-length method for logging and there has always been a constant quest to make it more efficient and sustainable. Reduction of forest soil damage and operator vibration dosages are crucial steps that could facilitate meeting the above stated targets. In this context Skogforsk- The Swedish Forest Research Institute has decided to explore the potential usage of caterpillar tracks on conventional wheeled forwarders. An efficient way to perform this study is to use multi body simulations to evaluate the performance of the tracked forwarder concept over different terrains. This thesis work aims to model and simulate a tracked forwarder in Adams ATV module. As part of the thesis a conventional wheeled forwarder was selected and a track unit was conceptualised to fit it. The concept was modelled and simulate with Adams ATV for various ground conditions. An effort was also made to identify the performance parameters required to improve traction, handling, and ride performance. Based on this some results were selected and studied and inferences were made. The results from the thesis work could provide a guideline on the methodology to be followed and a a deliverable is also a multi-body dynamics model for future design research. / Svensk skogsindustri jobbar efter kortvirkesmetoden för trädavverkning. Det finns en strävan efter att göra denna metod mer effektiv och samtidigt mer ekologiskt hållbar, exempelvis en minskad markpåverkan reduktion av de helkroppsvibrationer som operatören utsätts för. Motivet till detta examensarbete är att utforska möjligheten att ersätta dagens hjulbaserade skogsmaskiner med banddrivna. Det överordnade syftet för examensarbetet är att utveckla en modelleringsmetodik för dynamiska systemsimuleringar. Metoden för detta är att modellera och simulera en banddriven skotare med Adams ATV-modul och att beskriva ett rekommenderat tillvägagångssätt och möjliga resultat. Som en del av arbetet har en traditionell skotare valts och en konceptuell bandenhet har skapats och anpassats för att passa till skogsmaskinen. Konceptet modellerades och simulerades med Adams ATV för olika markunderlag. Ytterligare arbete lades på att identifiera de parametrar som är viktiga för grepp, fordonskontroll och framkomlighet. Baserat på några av resultaten valdes några för en fördjupad studie. Resultatet från examensarbetet kan ge riktlinjer för val av lämplig metodik för denna typ av prestandastudier. En konkret leverabel från projektet är också en dynamisk flerkroppsmodell, som kan utgöra en bas för fortsatta konstruktions- och prestandastudier.

Modulation de l’expression du transporteur vésiculaire du glutamate : implication dans la plasticité des neurones dopaminergiques

Dal Bo, Grégory 07 1900 (has links)
De nombreuses études ont établi que la majorité des neurones libèrent plus qu’une substance chimique. Il est bien connu que les neurones peuvent co-exprimer et co-libérer des neuropeptides en plus de leur neurotransmetteur, mais des évidences de la co-libération de deux petits neurotransmetteurs à action rapide se sont accumulées récemment. Des enregistrements électrophysiologiques ont aussi montré que des neurones sérotoninergiques et dopaminergiques isolés peuvent libérer du glutamate quand ils sont placés en culture. De plus, la présence de glutamate et de glutaminase a été détectée dans des neurones sérotoninergiques, dopaminergiques et noradrénergiques par immunomarquage sur des tranches de cerveau. Malheureusement, en considérant le rôle métabolique du glutamate, sa détection immunologique n’est pas suffisante pour assurer le phénotype glutamatergique d’un neurone. Récemment, la découverte de trois transporteurs vésiculaires du glutamate (VGLUT1-3) a grandement facilité l’identification des neurones glutamatergiques. Ces transporteurs sont nécessaires pour la libération de glutamate et constituent les premiers marqueurs morphologiques du phénotype glutamatergique. Il a été démontré que des neurones noradrénergiques expriment VGLUT2 et que des neurones sérotoninergiques expriment VGLUT3. Mais aucune évidence d’expression d’un des sous-types de VGLUT n’a été reportée pour les neurones dopaminergiques. Le but de notre travail était d’identifier quel sous-type de VGLUT est exprimé par les neurones dopaminergiques mésencéphaliques, et de déterminer si le phénotype glutamatergique de ces neurones peut être modulé dans des conditions particulières. Premièrement, nous avons utilisé des microcultures pour isoler les neurones dopaminergiques et des doubles marquages immunocytochimiques pour observer l’expression de VGLUT dans les neurones positifs pour la tyrosine hydroxylase (TH). Nous avons montré que la majorité (80%) des neurones TH+ isolés exprime spécifiquement VGLUT2. Cette expression est précoce au cours du développement in vitro et limitée aux projections axonales des neurones dopaminergiques. Toutefois, cette forte expression in vitro contraste avec la non-détection de ce transporteur dans les rats adultes in vivo. Nous avons décidé ensuite de regarder si l’expression de VGLUT2 pouvait être régulée pendant le développement cérébral de jeunes rats et sous des conditions traumatiques, par double hybridation in situ. Entre 14 et 16 jours embryonnaires, les marquages de VGLUT2 et de TH montraient une superposition significative qui n’était pas retrouvée à des stades ultérieurs. Dans le mésencéphale de jeunes rats postnataux, nous avons détecté l’ARNm de VGLUT2 dans environs 1-2% des neurones exprimant l’ARNm de TH dans la substance noire et l’aire tegmentaire ventrale (ATV). Pour explorer la régulation de l’expression de VGLUT2 dans des conditions traumatiques, nous avons utilisé la 6-hydroxydopamine (6-OHDA) pour léser les neurones dopaminergiques dans les jeunes rats. Dix jours après la chirurgie, nous avons trouvé que 27% des neurones dopaminergiques survivants dans l’ATV exprimaient l’ARNm de VGLUT2 dans les rats 6-OHDA. Finalement, nous avons observé la colocalisation de la protéine VGLUT2 dans les terminaisons TH positives par microscopie électronique. Dans les rats normaux, la protéine VGLUT2 est retrouvée dans 28% des terminaisons axonales TH dans le noyau accumbens. Dans les rats lésés à la 6-OHDA, nous avons observé une diminution considérable des terminaisons TH positives, et une augmentation dans la proportion (37%) des terminaisons dopaminergiques présentant du VGLUT2. Nos résultats suggèrent que le phénotype glutamatergique des neurones dopaminergiques est régulé au cours du développement, peut être réactivé dans des états pathologiques, et que ces neurones peuvent libérer du glutamate dans conditions spécifiques. / Numerous studies have established that the majority of neurons release more than one chemical substance. It is well known that neurons can co-express and co-release neuropeptides in addition to their neurotransmitter, but evidence of co-release of two small and fast-acting neurotransmitters has been accumulated recently. Electrophysiological recordings have also shown that isolated serotonine and dopamine neurons can release glutamate as a co-transmitter when they are placed in culture. Furthermore, the presence of glutamate and glutaminase has been detected in serotonine, dopamine and noradrenaline neurons by immunolabelling in brain slices. Unfortunately, considering the metabolic role of glutamate, its immunodetection is not sufficient to assert the glutamatergic phenotype of a neuron. Recently, the discovery of three vesicular glutamate transporters (VGLUT1-3) has greatly facilitated the identification of glutamate neurons. These transporters are necessary for the glutamate release by neurons and constitute the first molecular markers of a glutamatergic phenotype. Interestingly, it was demonstrated that some noradrenaline neurons express VGLUT2 and that some serotonin neurons express VGLUT3. But no evidence for expression of any VGLUT subtypes was initially reported for dopamine neurons. The goal of our work was to identify which VGLUT subtype is expressed by mesencephalic dopamine neurons, and to determine if the glutamatergic phenotype of these neurons can be modulated under specific conditions. First, we used microcultures to isolate dopamine neurons and double immunocytochemistry to visualize VGLUT expression in tyrosine hydroxylase (TH) positive neurons. We showed that the majority (80%) of isolated TH+ neurons express specifically VGLUT2. This expression occurred early during in vitro development and was limited to axonal projections of dopamine neurons. However, this strong expression in vitro contrasted with the lack of detection of this transporter in adult rats in vivo. We next decided to investigate if VGLUT2 expression could be regulated during brain development of young rats and under traumatic conditions, using double in situ hybridization. At embryonic days 14 to 16, VGLUT2 and TH labelling displayed significant overlap which was no longer found at later stages. In postnatal mesencephalon of young rats, we detected VGLUT2 mRNA in approximately 1-2% of neurons expressing TH mRNA in the substantia nigra and in ventral tegmental area (VTA). To explore the regulation of VGLUT2 expression under traumatic condition, we used 6-hydroxydopamine (6-OHDA) to damage dopamine neurons in young rats. Ten days post-surgery, we found that 27% of surviving dopamine neurons in the VTA expressed VGLUT2 mRNA in 6-OHDA animals. Finally, we observed the colocalisation of VGLUT2 protein in TH positive terminals by electron microscopy. In normal rats, VGLUT2 protein was found in 28% of TH positive axon terminals in nucleus accumbens. In 6 OHDA-lesioned rats, we observed a considerable reduction of TH positive terminals, and an increase in the proportion (37%) of dopamine terminals displaying VGLUT2. Our results suggest that the glutamatergic phenotype of dopamine neurons is developmentally regulated, can be reactivated under pathological states, and that these neurons are able to release glutamate under specific conditions.
