The project developed in the master's degree in M2-P, proposes a technology of hollow metal components DX53D+Z275N+NC with holes sheet metal forming. For batch production 225 000 units per year, on the basis of literary study problems of production of components there is designed a new way of producing components for progressive tools and it is compared with current production of simple tools. A progressive tool has 12 steps and combines them in cutting, drawing and extrusion. The tool is mounted in the hydraulic press KAISER KSTU2500 with a maximum force of 2500 kN. Simulations were performed for the campaign in the PAM-STAMP 2G 2011.

This thesis introduces a representation of graphical data, progressive meshes, and its fields of usage. The main part of this work is mathematical representation of progressive meshes and the simplification algorithm, which leads to this representation. Examples of changes in progressive mesh representation are also part of this thesis, along with few examples. The result is an application that implements the calculation of the Progressive Meshes model representation

Since the late 80s the web has been evolving through new standards, added functionality, device performance and improved user experience. Websites evolved from static information to what is now known as web apps in which web technologies started to replace regular native programs and apps, as web apps slowly started offering similar functionality and performance, with the added benefit of being cross-platform. Over time, even more functionality and improvements were added to the web apps which, with the right combination, made them progressively become more like apps. In 2015, this combination got named by Google as Progressive Web Apps (PWA) which allow users to add web apps to their home-screens and use them like native apps. PWAs can support being used offline, give notifications, use the device’s hardware and more. In this thesis, the compatibility, performance, security, privacy, and user/business impact of fundamental elements of PWA are researched through literature review and experimental analysis. Eight browsers are tested on four operating systems for compatibility of the Service Worker, Web App Manifest, add to home-screen ability and offline usage functionality. For performance, tests are done on a website called Fleet Management System (FMS) which is a track and trace system for Inter-Data Europe b.v. who will keep using the implementation and knowledge created from this study. For security, privacy and user/business impact, a literature review is done on past studies, use-cases and discoveries made during the implementation and tests. The results show that most of PWA’s fundamental functionality is supported by most major browsers, especially on Android and on Chromium browsers, with the exception of iOS in which only Safari supports anything to do with PWA. Performance is found to be heavily dependent on implementation strategy but can make a significant difference if implemented correctly. Security is found to allow certain abuse and sensitive data leaks depending on implementation. Furthermore, user reengagement and revenue of major companies are found to increase significantly after implementing PWA.

Indiana University-Purdue University Indianapolis (IUPUI) / This thesis examines the motivations of the Woman’s Council of National Defense. It will examine how women in Indiana and Illinois organized their state and local councils of defense as they embraced home-front mobilization efforts. It will also show that Hoosier women, like women across the United States, became involved in World War One home-front mobilization, in part, to prove their responsibility to the government in order to make an irrefutable claim for suffrage. As a result of extensive home-front mobilization efforts by women, the government was able to fulfill its own agenda of creating a comprehensive record of its citizens, thus guaranteeing a roster of citizens eligible for future wartime mobilization. By examining the Child Welfare Committee and the Children’s Year in a broad view, this thesis supports the assertions of historians like Robert G. Barrows, William J. Breen, and Lynn Dumenil, who have shown how Progressive-minded women advanced Progressive reforms by embracing the war effort and using it to their own advantage.

We used a combined multi-element, ABCBC reversal design to examine whether qualities of various negative reinforcers can be assessed under progressive-ratio schedules. Two adults with disabilities participated in this study. We assessed five sounds three times using progressive-ratio schedules to obtain mean break points for each stimulus and ranked negative reinforcers according to their mean break points. We called the stimulus with the highest mean break point the high-quality escape (HQE) stimulus and the stimulus with the lowest break point the low-quality escape (LQE) stimulus and examined responding according to different schedules of reinforcement for each stimulus: FR2, FR4, and FR8 for Jenny and FR1 and FR11 for April. We identified preferred and nonpreferred sounds for both participants.We observed differential responding for both participants between preferred and nonpreferred sounds. We observed differential responding between HQE and LQE stimuli for April but not for Jenny; a larger range in break points was observed for April. These results demonstrate a method to identify preferred and nonpreferred sounds and provide support for the possibility of using progressive-ratio schedules to rank negative reinforcers of various qualities.

Problem gambling is a growing social concern that results in debt, lost jobs, broken families, and at times, suicide. Slot machines are the most popular and most addictive form of gambling, generating nearly 70% of annual profits for the commercial casino industry in North America. Behavioral researchers have identified variables that establish and maintain problem gambling on slot machines, and the data reveal characteristics that influence preference for specific games, and subsequently, time spent engaged with specific machines. A degree of variability has been reported in the outcomes observed across participants and studies; such variability may be influenced by generic features of the games used by researchers utilizing a “one machine suits all” approach to slot research, i.e., within most studies a single machine is used for all participants rather than chosen according to participant preference for the machine or features therein. The following set of studies aimed to investigate variables related to slot machine selection, gambler preference for structural characteristics, and the reinforcing effectiveness of the machine on gambling behavior. The first of three experiments evaluated participant preference for functional and structural characteristics of popular three-, four- and five-reel electronic Vegas-style slot machines according to (a) a Likert rating scale of attitudes toward the machines, (b) forced ranking of most-preferred machines, and (c) a paired-stimulus preference assessment. Experiment II utilized a series of multiple schedules randomized across participants to examine differences in the rate of play when participants gambled on their most- and least-preferred machines. In Experiment III, the reinforcing effectiveness of the machines was evaluated. Participants engaged in an arbitrary task to gain access to their highest- and least-preferred machines as indicated in Experiment I. Response effort during the work task was evaluated under a progressive ratio schedule of reinforcement to determine the degree to which the individual would work to gain access to the machine. Participant break points were compared across the two conditions. Results of Experiment I yielded significant differences in the degree to which participants rated the machines: three-reel machines and those displaying a win were rated significantly higher in the attitude assessment when compared to four- or five-reel machines, and when compared to those with a loss, respectively. During the forced ranking procedure, participants again selected three-reel machines significantly more frequently in their “top five” favorite machines than four- or five-reel options. Last, when subjected to the paired stimulus preference assessment, participants selected three-reel machines on a significantly higher percentage of trials than five-reel alternatives. Results of Experiment II demonstrated that rate of play on high-preference machines is on average, faster than rate of play on lower-preference machines, and results from Experiment III yielded on average, higher break points in participant responding when offered the opportunity to gamble on high-preference slot machines following a response requirement than when offered a low-preference option; however, the average rate of response on the work task that led to machine access was lower during high-preference conditions than low-preference conditions. Implications of these findings for the gambling literature and for the effective prevention and treatment of disordered slot machine gambling are discussed.
