Příprava nové IT služby telefonního operátora / Development of a new IT service of a telephone service provider

Králíčková, Lenka January 2014 (has links)
This diploma thesis deals with the analysis of launching a new IT product on the Czech market. It focuses on small businesses and introduces an IT product intended for this specific kind of a clientele. There is no such a product on the market, which leads to an excellent potential in this field. On the basis of experience, the company in which the IT product is introduced finds it crucial to develop a reliable marketing mix as well as strategy because it is difficult to offer these IT products to people owning smalls businesses who do not understand the technological aspects of such products. The theoretical part, therefore, provides the definition of the main marketing terms, B2B market, marketing strategy, marketing mix, SWOT analysis and a detailed description of launching a new product on the market, including the explanation of the differences between launching a product and service. The practical part of this paper gives information about a telephone service provider and its major competitors and it describes the IT products situation on the Czech market. The thesis also recommends a particular marketing mix of the selected product and a sale strategy. The success rate of the product is analysed on the basis of an interview with a small business and the opinion of the manager of a company in which the product is introduced.

Parent-Child Dyadic Experiences Living with Postural Orthostatic Tachycardia Syndrome (POTS) during Emerging Adulthood

Farchtchi, Masumeh Auguste 08 May 2020 (has links)
Chronic illness and invisible disability are impactful contexts during emerging adulthood and the launching stage of the family life cycle (Beatty, 2011; Capelle, Visser, and Vosman, 2016; Young et al., 2010). The parent-child relationship is important to both developmental and health outcomes in families coping with chronic illness during emerging adulthood (Crandell, Sandelowski, Leeman, Haville, and Knafle, 2018; Fenton, Ferries, Ko, Javalkar, and Hooper, 2015; Waldboth, Patch, Mahrer-Imhaf, and Metcalfe, 2016). While informed clinical competency in counseling families experiencing disablement is a diversity-affirmative ethical imperative among psychotherapists (Mona et al., 2017), little is known in family therapy about how parents and emerging adult children experience launching with chronic illness. This qualitative study explored the parent-child dyadic experience of living with a chronic illness called Postural Orthostatic Tachycardia Syndrome (POTS) during emerging adulthood. Seven dyads of parents and their emerging adult children with POTS were interviewed. Data analysis of in-depth interviews using Moustakas's (1994) transcendental phenomenology uncovered eight thematic clusters of meaning in the shared lived experience of POTS at the launching stage of the family life cycle. Clinical implications for family therapists were explored using Rolland's family system-illness (FSI) model of medical family therapy. Study limitations and future directions for further research were discussed. / Master of Science / More and more young adults are living with chronic illness. Postural Orthostatic Tachycardia Syndrome (POTS) is a little-known chronic illness that tends to begin during adolescence. Like many health problems that disproportionately affect women, POTS is often overlooked by doctors. POTS symptoms, such as dizziness and cognitive difficulty, impact a person's ability to engage in preferred activities and identities. Family therapists can play an impactful role in supporting parents and children with POTS through developmental tasks related to launching an emerging adult in the context of this complex and widely misunderstood chronic illness. This thesis presented the first qualitative study of parent-child dyadic experiences living with POTS. Clinical implications for medical family therapy were highlighted. To construct an interview framework, Rolland's Family Systems-Illness (FSI) clinical model for helping families cope with illness and disability was used in conjunction with Arnett's description of emerging adulthood as a developmental stage in life. Seven parent-child dyads were interviewed for 1-2 hours in fourteen separate interviews generating transcripts about 140,000 words long in total. Analysis of these interviews identified shared themes composing the essence of the parent-child experience living with POTS during emerging adulthood. Results were described through tables and narratives. Clinical implications for family therapists working with parents and children with POTS during emerging adulthood were proposed. Limitations and ideas for future studies were discussed.

Dálniční estakáda přes široké údolí / Highway multispan bridge over wide wally

Bobek, Lukáš January 2017 (has links)
The aim of this diploma thesis is to design and assess highway bridge. The structure is located on the D1 motorway section bridging a wide valley between the Slovak villages Doľany a Klčov. Three variants have been created – box girder bridge with transverse overhangs, a pair of girder bridge and a pair of box girder bridges. The various proposals were compared with each other. For the most valuable option is selected prestressed box girder bridge with transverse overhangs, which are supported by prefabricated concrete struts. The selected proposal was subsequently elaborated in detail, the load-bearing structure is analyzed using Scia Engineer 16. In calculating the internal forces is adjusted for the effects of construction methods, even as time-dependent analysis TDA. When designing the load-bearing structure it is considered the action of permanent load, also loading from transport and temperature. The structure is assessed for serviceability and ultimate limit states according to current standards. The bridge deck is built by incremental launching method. The principle of this method consists of building the segments in a casting yard located behind the bridge abutment. Each segment is matchcast against the previous one and prestressed to the section of structure already built. The whole superstructure is then jacked forward a distance equal to the length of this segment. This process is repeated until the bridge deck is in its final position. Chosen method of construction is very fast and efficient, to the country in the valley isn´t damage during construction.

Study of quasi-periodic architectured materials : Vibrations, dynamic fracture and homogenization / Etude des matériaux architecturés quasi-périodiques : Vibrations, fissuration dynamique et homogénéisation

Glacet, Arthur 13 July 2018 (has links)
Les Structures atomiques Quasi-périodiques (QP) possèdent des propriétés particulières, notamment dans le domaine vibrationnel. Il pourrait être intéressant de pouvoir transférer ces propriétés à des méta-matériaux macroscopiques. Des réseaux de poutres quasi-périodiques 2D sont étudiés dans cette thèse dans le cadre du modèle élément finis (EF) poutre Euler Bernoulli. Ces réseaux de poutres peuvent facilement être produits par fabrication additive ou par découpe laser. Il est possible de faire varier l'élancement des poutres (le ratio hauteur sur longueur) qui est un paramètre intéressant pour modifier la réponse mécanique du réseau. En utilisant la méthode EF, l'influence de l'élancement des poutres sur la réponse vibratoire des réseaux de poutres QP est étudiée. La méthode numérique Kernel Polynomial (KPM) est adaptée avec succès de la dynamique moléculaire aux réseaux de poutres pour étudier leurs modes de vibration sans avoir à diagonaliser complètement la matrice dynamique. Les réseaux de poutres QP présentent des propriétés similaires à leur compère atomique: en particulier la localisation de modes sur des sous-structures et une relation de dispersion hiérarchisée. Le comportement à la fracture est aussi étudié étant donné que les symétries présentes dans les QP pourraient permettre des réseaux de poutres ne présentant pas de plans faibles pour la propagation de fissures. Cela a été démontré d'après des calculs EF statiques avec un critère de fracture fragile sur l'énergie de déformation. Les simulations statiques ne suffisent pas car elles ne peuvent pas capturer les phénomènes dynamiques complexes qui apparaissent lors de la fissuration fragile. Les propriétés de vibration du QP pourraient aussi avoir un impact sur la propagation dynamique de fissure. Un modèle dynamique de fissuration est développé afin d'étudier l'impact de l'élancement sur la capacité des réseaux de poutres QP à dissiper de l'énergie par fissuration. Finalement une méthode Coarse Graining est développée pour identifier un milieu Cosserat continu équivalant au réseau de poutres QP pour différentes échelles. Cette méthode permet d'identifier la densité, les déformations, les contraintes et donc les modules d'élasticité du milieu Cosserat équivalent, permettant ainsi une meilleure compréhension du rôle des sous structures précédemment identifiées. / Quasi periodic (QP) structures have shown peculiar properties in the atomistic domain, especially the vibrational one. It could be interesting to be able to transpose these properties in macroscopic meta-materials. Quasi periodic 2D beam lattices are studied in this thesis due to the simplicity of the Euler Bernoulli finite element (FE) model. These beam lattices can easily be produced by additive manufacturing or by laser cutting. It is possible to vary the beam slenderness (i.e the ratio of height over length) that is a interesting parameter to modify the mechanical response of the lattice. Using finite element method, the influence of the beam slenderness over the vibration behavior of the QP beam lattices will be studied. The Kernel Polynomial numerical Method (KPM) is successfully adapted from molecular dynamics simulations in order to study vibrational modes of FE beam lattices without having to fully diagonalize the dynamical matrix. The QP lattices show similar properties as their atomic counterpart e.g mode localization over sub-stuctures and hierarchical dispersion relation. The fracture behavior is also studied, as the special symmetries allowed by the quasi periodicity could result in beam lattices without weak planes for crack propagation. It was proved to be true from static FE simulations with a brittle strain energy breaking criterion. Static simulations were not enough and do not grasp the complex dynamical phenomena taking place in brittle fracture. A dynamic crack propagation model was thus developed. The vibrational properties of quasi periodic structures could also have an impact on the dynamic crack propagation. Several simulations are run in order to study the impact of the slenderness on the energy dissipated by fracture of QP lattices. Finally, a coarse graining method (CG) was developed to identify a continuous Cosserat medium at different scales from the FE beam model. This CG method allows to identify, density, strain, stress and elastic moduli of an equivalent continuous Cosserat. This allows a better understanding of the role of previously identified characteristic sub structures.

以家庭系統觀進行家庭測量之研究—以家庭分化為例 / The Research of System Measurement as Family System Paradigm:The Example of Family Differentiation

孫頌賢, Sun, Sung-Hsien Unknown Date (has links)
本研究乃依據家庭系統理論的觀點,欲探討家庭分化的測量問題與內涵,以企圖進行不同成員間觀點的測量與相關問題探討。其以「起飛期家庭」之在大學就讀學生為主要測量中心,但測量單位以家庭為單位,包括起飛期家庭中的大學生或研究生、父、母等三人,正式研究結果共蒐集到77個家庭的分化資料。主要研究結果可分成六個方面: 第一,研究發現成員間同時具備「一致性」與「不一致性」的現象,此種「同中有異」、「異中有同」的系統特性,反映出系統測量時的獨特之處,在此方面的重要結果包括1.系統不一致性的現象受到不同家庭分化議題的影響;2.孩子與父母間對於「父母關係」中的分化內涵有較大的不一致性;3.父親與孩子之間對於「親子關係」的分化內涵有較大的不一致性;4.母親與孩子以及母親與父親間在不同雙人關係的分化內涵上,有較多的一致性;5.母親與女孩比母親對男孩之間有較多「情感共振」的糾葛;6.系統的一致性表現受到不同雙人組合方式以及不同分化內涵而有所差異。 第二,在驗證系統理論方面,其結果包括1.家庭系統中不同成員對分化的內涵總和不等於系統本身的分化內涵;2.家庭整體性並不能成功的被驗證,但父子次系統、母子次系統、父母次系統確實存在;3.驗證父子次系統、母子次系統、父母次系統之間具有相關連性。 第三,在多元化的測量內涵上,研究發現,原本Wood所發展出的接近性分化內涵並不能夠清楚的被驗證,但以「情感共振」與「干涉侵權」兩大因素之架構,可發現較適配的因素架構,而「情感共振」因素較適合進行整體系統的測量。 第四,在多元化測量面向中之不同對象上,發現進行家庭系統測量時,其測量單位應以「整個家庭」為單位,故測量對象應包括父、母、子三者,所獲得的資料會更接近系統系也更加豐富。 第五,在多元化測量面向中之不同次系統上,進行家庭系統測量時,必須將不同次系統分開測量,且不同次系統所著重的分化內涵之議題可能有所不同,而每個成員對於不同次系統之知覺分化內涵也可能有所不同,尤其是在「親子關係」和「夫妻關係」、以及「母子關係」與「母女關係」有顯著不同的分化內涵。 第六,在家庭系統分析方法上,不同成員間觀點之差異性是確實存在的,若使用「平均數法」與「差異數法」,則可能消弭了成員間的不一致性,故過去傳統使用「平均數法」與「差異數法」處理系統資料是較不適合的。 最後針對此研究結果,討論系統測量時的原則與方法,以及在實務上的啟發與建議。

Seguindo a perspectiva do empreendedorismo como método, ela representa uma ruptura nos estudos de empreendedorismo, pois é diferente da abordagem preditiva utilizada até então em que elabora-se um plano de negócios e, somente depois da busca de investimentos, o produto é testado com clientes. Embora muito utilizada, existem poucos estudos acadêmicos sobre as práticas Lean aplicadas a Startups, daí a relevância do presente estudo. Com caráter exploratório, a pesquisa utiliza uma metodologia quantitativa e se vale de uma survey, respondida por 115 empreendedores, sócios de empresas de base tecnológica com até 42 meses de existência, com o objetivo de descobrir se eles conhecem a Lean Startup, o quanto suas ferramentas são adotadas e se elas trazem efeitos positivos. Como resultado, constatou-se que a Lean Startup é amplamente conhecida e utilizada, foram encontradas sinalizações de resultados positivos obtidos pelo uso de algumas de suas ferramentas - feedback acelerado, produto mínimo viável (PMV) e métricas da contabilidade para inovação, que medem o aprendizado no lugar de lucro. Dessa forma, a pesquisa contribui com o aumento do conhecimento sobre a Lean Startup, bem como por meio da formulação de perguntas para direcionar estudo futuros. / Since 2012, several entrepreneurs in Brazil have adopted an approach to business creation called 'Lean Startup', which began to be disseminated with the publication of the book The Lean Startup by Eric Ries. Following the perspective of entrepreneurship as a method, it represents a break in entrepreneurship studies because of its difference from the traditional predictive approach in which a business plan is developed. Only after the pursuit of investments is the product tested with customers. Although widening in use, there are few academic studies on lean startup practices, hence the relevance of this study. Using an exploratory character, this research uses a quantitative methodology and relies on a survey answered by 115 entrepreneurs from technology-based companies with up to 42 months of existence, in order to find out the extent of their knowledge of the lean startup method, how its tools were adopted and if they brought positive effects. As a result, it was discovered that the lean startup method is widely known and used. Evidence was found of positive experience from using some of the practices, such as fast feedback, minimum viable product (MVP) and in accounting for innovation - metrics that measure the entrepreneur’s learning instead of profit. Thus, the research contributes to the increase of knowledge about the Lean Startup, as well as through the formulation of questions to guide future study.

Influence de la structure de stratégie de lancement sur le succès de nouveaux produits : le cas de l'industrie pharmaceutique iranienne / Influence of Launching Strategy Structure on New Product Success : A Case of Iranian Pharmaceutical Industry

Azadi, Mohammad 12 December 2011 (has links)
Nous présentons un modèle de recherche qui permet d'étudier de nombreuses complexités desstratégies de lancement de nouveaux produits, de tester de façon empirique les relationshypothétiques entre les décisions de lancement, de diffuser des connaissances sur les façonsdont les managers ont tendance à élaborer diverses options de décision de lancement enstratégies de lancement génériques, et de lier le succès de nouveaux produits aux stratégiesgénériques des managers. Les données de cette recherche ont été recueillies d'octobre 2010 àjanvier 2011 au sein de l'industrie pharmaceutique iranienne. La taille de l'échantillon est de500 projets de nouveaux produits. Les répondants doivent avoir une expérience de lancementd'au moins cinq nouveaux produits, depuis janvier 2007, pour pouvoir répondre à cette étude.Nous avons demandé aux managers du marketing de sélectionner des projets de nouveauxproduits introduits après janvier 2007 par leurs entreprises, définis par celles-ci commeclairement commerciaux, et de répondre à cette enquête en fonction de l'introduction de ceproduit. Ainsi, plusieurs décisions prises par les managers lors du lancement de nouveauxproduits impliquent des choix d'options de lancement cohérents avec les choix de lancementdéjà effectués. Sur la base des données, nous identifions également trois stratégies delancement génériques, en fonction desquelles la réussite du nouveau produit eststatistiquement variable. Bien que l'ensemble de décisions, que comprend chaque stratégie, estseulement une petite portion de l'ensemble étudié, nous constatons que ces ensembles dedécisions sont associés à divers niveaux de succès. Nous étudions également les effets desréactions compétitives sur la structure de stratégie de lancement et la réussite du nouveauproduit. / We present a research model that allows the investigation of many of the complexities of newproduct launch strategies, empirically test for hypothesized relationships among launchdecisions, spread knowledge on the ways in which managers tend to build choices amonglaunch decision options into generic launch strategies and link new product success tomanagers' generic strategies. The data for this research was collected from October 2010 toJanuary 2011 in Iranian pharmaceutical industry. Sample size is 500 new product projects.XIThe respondents should have experience on launching at least five or more new product sinceJanuary 2007 in order to be qualified to answer this study. We asked marketing managers toselect new product projects introduced after January 2007 by their firms, defined by the firmsas a clear commercial and answer this survey based on the case of that product introduction.Thus, several decisions managers make in the new product launch require choosing launchdecision options consistent with already made launch choices. From the data, we also identifythree generic launch strategies across which new product success statistically varies. Althoughthe set of decisions, which comprises each strategy, is only a smaller portion of the full setinvestigated, we find that these decision sets are associated with different levels of success.We also study effects of competitive reactions on launch strategy structure and new productsuccess.

Ocelová konstrukce silničního mostu / Steel construction of the road bridge

Kloda, Petr January 2019 (has links)
The aim of the master thesis was a design of the steel-concrete composite road bridge for a main road in Ostrava. The part of the design was a variant design of the bridge which has theoretical spans equal to 44 m + 55 m + 44 m. Total span of the bridge is then 143 m. Two variants of the bearing steel structure are compared in the preliminary structural design, in the first one a twin-girder is designed and in the second one a box-girder bridge is assessed. The width of the bridge is 14 m and a launching of the bridge without temporary supports is chosen as the assembly method. The design of the bridge structure was carried out according to the valid standard ČSN EN. The final thesis contains variant design, structural design report, where a bill of quantities is stated, engineering report and drawings.
