It will also give the reader a presentation of the company Clean Air Technologies, which for the most part constructs cleaning facilities for power plants. How to create 3D-libraries for some of those facilities will be introduced in this composition. The collaboration with Clean Air Technologies has resulted in several 3D animated movies and rendered images.

IDAPS CAD-BASED STORE SEPARATION ANALYSIS OF DEPLOYABLE SURFACES

Paulick, Michael J. 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The Image Data Automated Processing System (IDAPS), developed by the 96th Communications Group Test and Analysis Division at Eglin AFB, uses a CAD-based image matching technique to calculate a trajectory of a store separation event. The latest evolution of this system has been in production for several years and has proven to be both an accurate and a valuable tool for evaluating flight releases of bombs, fuel tanks, missiles, and other stores. This paper describes a prototype capability that is being developed for assessing fin and wing deployment angles.

Innovator Sorting and Firm Size

January 2016 (has links)
abstract: This paper examines the link between firm size and innovation. Given that innovation is highly reliant on human capital, the ability to attract, motivate, and retain high quality inventors is a key determinant of firm innovation. Firm size may affect these abilities, and small firms are known to account for a disproportionate share of aggregate innovation. I therefore investigate the role that sorting of inventors across firms plays in explaining this disparity. Talented inventors may find employment at a large firm less attractive due to the relative absence of growth options and a lower ability to link compensation to performance. Using inventor-level patent data, I construct employment histories for inventors at U.S. public firms. I find that the most productive inventors are disproportionately likely to move to small firms, while the least productive inventors disproportionately remain at large firms. These results cannot be explained fully by small firms' superior growth opportunities. In addition, productive innovators' turnover in small firms is sensitive to the level of option compensation. Taken together, this evidence is consistent with inventor sorting explaining part of the firm size innovation gap. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2016

Embedded Relations and Marketing Capabilities

Venkataramani, Sangeetha January 2015 (has links)
This dissertation explores the role of capacities of different sets of actors and examines some of the consequences of realization of these capacities. Specifically, the two outcomes examined in this dissertation are coopetition, which is simultaneous cooperation and competition, and innovation. This research uses different contexts and multiple methods to understand and explore the role of capacities in varied outcomes. The first essay examines the effect of actor capacities on coopetition. It looks at cosmetics salespeople in department stores that are embedded in relations with the store and the cosmetics brands among others, and examines the effect of this embeddedness on cooperative or competitive responses of these salespeople. Specifically, this research posits that actors, both human and non-human, possess capacities to interact with other actors. Unless the interaction occurs, the capacity merely remains a potential, and is only realized in interaction. Capacities represent the joint agency of interacting actors or entities. Both individual actors and collectives possess capacities to interact with others. Capacities of actors and collectives determine the processes employed by these actors that help integrate the collective or disintegrate it, thereby dynamically influencing the balance between cooperation and competition among sales people. The second essay examines the capacities of inventors in Biotechnology industry and investigates innovation as an outcome of realization of their capacities. This essay specifically focuses on actor capacities and its outcomes in the event of an acquisition. It posits that potential relational capacities of inventors prior to an acquisition determines whether integration among inventors will happen at the time of the acquisition. In addition, this research studies the effect of inventor integration at the time of acquisition on innovation outcomes of the acquiring firm, four years from the time of acquisition.

Dviračių ratlankių sujungimo staklės / The Connection Machine for Bicycle Rims

Vaitkus, Svajūnas 02 July 2012 (has links)
Bakalaurinio projekto tema – technologinis įrenginys, kurį naudoja dviračių gamybos įmonė „Baltik – Vairas“. Šio įrenginio racionalūs inžinieriniai projektavimo darbai reikšmingi įmonės ūkinei veiklai. Įmonė dirba dviem kryptimis: naudoja energiją taupančias technologijas ir sudaro racionalias mechanines technologines sistemas, pasižyminčias dideliu darbo našumu. Šie klausimai yra nagrinėjami šiame projekte. Ratlankių sujungimo staklių projektavimas sudarytas iš komplekso inžinierinių uždavinių. Todėl šiame darbe sprendžiamos tik šio komplekso atskiros dedamosios, vertinant pradinę informaciją, realias darbo apkrovimo charakteristikas ir staklių efektyvumo išnaudojimo laipsnį. Pagrindinė sąlyga, projektuojant kokybišką technologinę mechaninę ratlankių sujungimo staklių sistemą, yra teisingas, optimalus pagrindinės mechaninės schemos parinkimas ir jos darbo režimai. Svarbu, kad ši staklių schema būtų susieta su kitais įrenginiais ir aplinka. Tai aptarnavimo patogumas, atitinkantis ergonomikos reikalavimus, ruošinių ir pagamintų detalių sandėliavimo vietos, transportavimo keliai ir priemonės. Šių klausimų sprendimai pateikti grafinėje projekto dalyje. Galimų skaičiavimo paklaidų multiplikacijai išvengti buvo atlikta projektuojamo objekto variantų analizė. Tai labai padidino ratlankių sujungimo staklių skaičiavimo reikšmių optimalumą. Pradinė informacija, kuria buvo naudojamasi atliekant diplominį projektą, yra apdirbamo mazgo, dviračio ratlankio, techniniai reikalavimai prieš... [toliau žr. visą tekstą] / The theme of dissertation is the Connection Machine for Bicycle Rims, which is used in company “Baltic – Vairas”. Rational engineering designing job of this mechanism is very important of company work. This company is working in two ways: using by mechanism, which are saving energy and making rational mechanical systems which are excellence in labour productivity. This is motif of dissertation. The designing of rim joint machine is made of group of engineer jobs. So, in this dissertation is handing separate components considering on primary information, real characteristic of workload and efficiency of machines exploitation. The designing of quality technical mechanical rim joint machine is crucial problem of choice optimal main scheme and his working mode. Importantly that this scheme would be united with other mechanisms and environments. Solution of these questions are discussed in the graphical part of dissertation. This very increased calculating expression of rim joint machine. The main information which was used in dissertation is bicycle rim technical requirements before and after technological processes.

Design and Structural Analysis of a Robotic Arm

Eranki, Venkata Krishna Prashanth, Reddy Gurudu, Rishank January 2017 (has links)
Automation is creating revolution in the present industrial sector, as it reduces manpower and time of production. Our project mainly deals around the shearing operation, were the sheet is picked manually and placed on the belt for shearing which involves risk factor. Our challenge is designing of pick and place operator to carry the sheet from the stack and place it in the shearing machine for the feeding. We have gone through different research papers, articles and had observed the advanced technologies used in other industries for the similar operation. After related study we have achieved the design of a 3-jointed robotic arm were the base is fixed and the remaining joints move in vertical and horizontal directions. The end effector is also designed such that to lift the sheet we use suction cups were the sheet is uplifted with a certain pressure. Here we used Creo-Parametric for design and Autodesk-Inventor 2017 to simulate the designed model.
