Abstract:
For complex sheet metal parts, multiple stamping stages are needed in a sequence. In today’s industry, intermediate parts are transferred between stages automatically by feeding as a strip (progressive die) or a blank (transfer die). Although progressive/transfer dies are highly automated, transfer system parameters need to be predefined. These parameters must ensure that the part is transferred to next stage quickly and safely. However, due to highly complex geometry and motion in the die system, these parameters are conventionally finalized manually according to designers’ experience. In this thesis, algorithms are proposed to optimize transfer system parameters in transfer die, according to the geometry and motion restrictions of the entire system. Two algorithms are proposed to complete a two-step optimization process. In the first step, the geometry of the die set and parts are analyzed. Based on Siemens NX software and customized kinematic model, motions of die components are simulated, an “Obstacle Map” is generated to record the potential collisions between parts (and grippers) and die set during the part transfer process. Obstacle map can be regarded as an inherent property of the entire die system geometry, which can be utilized not only for the optimization algorithm proposed in the second step, but also for future research. In the second step, with obstacle map, motions of the transfer system are analyzed. According to system motion capacity and freedom of modification in practice, transfer system parameters are optimized. The core of the algorithm in this step is to apply overlap between motions to reduce the transfer duration. Lift stroke and press stroke are also optimized when modifications are allowed. The optimized transfer system parameters result in improved strokes per minute, while all the obstacles in the obstacle map are bypassed. One case study for a typical transfer die system with 14 initial SPM is performed to show the effectiveness of the proposed algorithms. Four levels of optimization are conducted with increasing freedom of modification: initial speed -> maximum speed -> allow lift stroke modification -> allow press stroke modification. The results show that the proposed algorithms are valid, SPM can be improved (22.9 -> 26.52 -> 26.61 -> 27.99) in different situations. Some topics can be further addressed based on the works in this thesis, future works can focus on algorithm expansion to progressive die, and algorithm improvements for more complex cases.

Abstract  Title: Information Technology and the Timing of Knowledge Transfer Methods: A study within six organizations in Sweden  Level: Master Thesis for Master’s Degree in Business Administration Author: Anna Thorsell and Filip LarssonSupervisor: Daniella FjellströmExaminer: Ehsanul Huda Chowdhury  Date: 2021 June  Aim: It has been stated that knowledge transfer processes fail due to poorly timed transfer methods and that it is of importance to understand underlying mechanisms of transfer. It has also been argued that information technology (IT) systems can increase knowledge transfer in organizations. This study aims to research the influence IT has on the timing of transfer methods and knowledge transfer. The authors of this study discovered a gap for the use and timing of IT transfer methods and its influence on knowledge transfer within organizations in existing research.  Method: This study included the use of secondary data from a literature review, as well as primary data using a qualitative research method with an inductive approach as semi- structured in-depth interviews were conducted for a multi-case study. The interviews were held with individuals working in six organizations in Sweden. Phases of analysis including content analysis and data coding were used for the analysis and reporting of the data collected.  Findings and Conclusion: The study showed that IT provides platforms for knowledge transfer through different types of IT and IT transfer methods used. That the type of IT chosen can depend on the urgency of the transfer, what type of knowledge is transferred as well as the amount of knowledge transferred. That the timing of IT transfer methods I can speed up knowledge transfer as it enables the transfer to happen faster and in later stages of the transfer process due to providing direct knowledge transfer channels and accessible knowledge to all members of a team. It was shown that IT transfer methods can influence internal stickiness, decrease causal ambiguity and reduce the knowledge barrier of arduous relationships as well as influence the use of front-loading and back- loading modes of transfer. That the urgency of transfer can be a determining factor for the modes used rather than the level of causal ambiguity of the knowledge.  Contribution of the Study: This study contributes to studies on types of IT and IT transfer methods used in organizations for knowledge transfer. It adds to existing research on timing of knowledge transfer methods including both explicit and tacit knowledge, as well as adding the influence of IT on the timing of knowledge transfer methods, knowledge transfer, internal stickiness, knowledge barriers and affordance of interaction. It provides new findings to the timing of knowledge transfer from the timing of types of IT and IT transfer methods used based on the urgency of transfer and what type of knowledge that is being transferred. The study contributes to highlighting the value of IT for the management of knowledge transfer within organizations, especially due to global events such as the COVID-19 pandemic. The study provides a basis for managers to examine their use of IT for knowledge transfer in organizations. It also showcases the continuous increased need for effective knowledge transfer processes between organizations, people and across locations and how IT can facilitate that.  Study Reflections and Suggestions for Future Research: This study included individuals from six organizations. It is suggested to include more participants for future studies as well as investigating teams, departments and organizations on narrow as well as on broader levels in different sectors to gain deeper insight into the field. Further research on how the urgency of transfer affects the modes of transfer used is also advised.  Keywords: Knowledge, Knowledge Transfer, Methods of Transfer, Timing, Modes of Transfer, Internal Stickiness, Information Technology, COVID-19

Abstract:
Massive deployment of diverse ultra-low power wireless devices necessitates the rapid development of communication protocols. Software Defined Radio (SDR) provides a flexible platform for deploying and evaluating real-world performance of these protocols. But SDR platform based communication systems suffer from high and unpredictable delays. There is a lack of comprehensive understanding of the characteristics of the delays experienced by these systems for new SDR platforms like LimeSDR. This knowledge gap needs to be filled in order to reduce these delays and better design protocols which can take advantage of these platforms. We design a GNU Radio based IEEE 802.15.4 experimental setup, where the data path is time-stamped at various points of interest to get a comprehensive understanding of the characteristics of the delays. Our analysis shows GNU Radio processing and LimeSDR buffering delay are the major delays in these data paths. We try to decrease the LimeSDR buffering delay by decreasing the USB transfer size but it comes at the cost of increased processing overhead. The USB transfer packet size is modified to investigate which USB transfer size provides the best balance between buffering delay and the processing overhead across two different host computers. Our experiments show that for the best-measured configuration the mean and jitter of latency decreases by 37% and 40% respectively for the host computer with higher processing resources. We also show that the throughput is not affected by these modifications. Higher processing resources help in handling higher processing overhead and can better reduce the buffering delay.
Stora installationer av heterogena extremt energisnåla trådlösa enheter ställer krav på snabb utveckling av kommunikationsprotokoll. Mjukvarubaserad radio (Software Defined Radio, SDR) tillhandahåller en flexibel plattform för att installera och utvärdera faktisk prestanda för dessa protokoll. Men SDR-baserade system har problem med stora och oförutsägbara fördröjningar. Verklig förståelse av hur dessa fördröjningar beter sig i nya plattform som LimeSDR saknas. Dessa kunskapsbrister behöver överbryggas för att kunna minska fördröjningarna och för att mer framgångsrikt kunna designa protokoll som drar nytta av de nya plattformarna. Vi skapar en försöksuppställning för IEEE 802.15.4 baserad på GNU Radio. Data som passerar systemet tidsstämplas för att ge underlag till att förstå fördröjningarnas egenskaper. Vår analys visar att fördröjningarna främst kommer från processande i GNU-radion och buffertider för LimeSDR. Vi försöker minska buffertiderna för LimeSDR genom att minska paketstorleken för USB-överföring, men det kommer till priset av ökade bearbetningskostnader. Paketstorleken för USB-överföring modifieras för att på två olika testdatorer undersöka den bästa balansen mellan buffertider och bearbetningskostnader. Våra experiment visar att för att den mest noggrant undersökta försöksuppställningen så minskar medelvärdet och jittret för fördröjningarna med 37% och 40% för testdatorn med mest beräkningskraft. Vi visar också att genomströmningen inte påverkas av dessa ändringar. Med mer beräkningskraft kan de ökade bearbetningskostnader hanteras, och buffertiderna kan förkortas mer effektivt.

Abstract:
The purpose of this study was to examine whether the feedback schedule controlled by the learner created an optimal environment for retention of motor skills. Two experiments were conducted and participants were randomly assigned to a Control (100% KR), 20% RF KR, Self-controlled and Yoked conditions. In experiment one an anticipation timing task and in experiment two a ball throwing task was used. The second experiment also included a transfer test in order to measure the persistence of the acquired capability for performance. Absolute constant error (&

) and variable error (VE) were calculated for four blocks of ten trials in acquisition phase and two blocks of ten trials in retention and transfer phases to analyze the subject&rsquo
s performances by repeated measures ANOVA. Experiment one analysis indicated significant main effects for groups in &
#9474
CE&
#9474
and VE. Participants in the self-controlled condition performed significantly better on retention test than the control group. Contrary to the expectations, experiment two analysis showed no significant differences between the groups in acquisition and retention tests. Group differences were only observed in transfer test between the 20% RF KR and Yoked conditions. There was an improvement in the performance by groups as they progressed through the acquisition trials. The results of the experiment were not consistent with regard to effects of KR on learning. The reasons might be attributed to several factors such as the age and the motivation of the subjects, and the nature of the task.

Abstract:
Timing jitter and phase noise are important design considerations in most electronic systems, particularly communication systems. The desire for faster transmission speeds and higher levels of integration, combined with lower signal levels and denser circuit boards has placed greater emphasis on managing problems related to phase noise, timing jitter, and timing distribution. This thesis reports original work on phase noise modelling in electronic systems. A new model is proposed which predicts the up-conversion of baseband noise to the carrier frequency in RF amplifiers. The new model is validated by comparing the predicted phase noise performance to experimental measurements as it applies to a common emitter (CE), bipolar junction transistor (BJT) amplifier. The results show that the proposed model correctly predicts the measured phase noise, including the shaping of the noise about the carrier frequency, and the dependence of phase noise on the amplifier parameters. In addition, new work relating to timing transfer in digital communication systems is presented. A new clock recovery algorithm is proposed for decoding timing information encoded using the synchronous residual time-stamp (SRTS) method. Again, theoretical analysis is verified by comparison with an experimental implementation. The results show that the new algorithm correctly recovers the source clock at the destination, and satisfies the jitter specification set out by the ITU-T for G.702 signals.

Cheung, Oi Lin. "Two Essays on the Role of Information in the Interaction between American Depository Receipts and Their Home Shares: Information Transfer and Issuer Decisions." ScholarWorks@UNO, 2008. http://scholarworks.uno.edu/td/855.

Full text
Abstract:
American Depository Receipts (ADRs) represent shares of foreign firms that are issued and traded in the U.S. Since an ADR and its underlying shares represent ownership interest of the same firm, they should be perfect substitutes in a perfect market. However, market imperfections such as differences in information environment, liquidity, investment and trading restrictions, taxes, control right, corporate governance might make them less-than-perfect substitutes. These imperfections, on the other hand, also present opportunities for research. This dissertation consists of two essays on ADRs, both related to the effects of less-thanperfect information. Specifically, the first essay examines the return and volatility transfers between ADRs and their underlying home shares. Our investigation differs from the previous studies in that we cover substantially more countries and that we attempt to explain the variations in the extents of transfer effects both across firms and across countries. Various hypotheses are developed, based on the premise that barriers associated with trading, investments, and corporate governance would lower the extent or effectiveness of transfers. Overall, our empirical results support these hypotheses. The second essay takes the viewpoint of the issuing firms. Supposedly, an issuer's timing and dollar amount raised depend on the conditions of three markets: its home equity market, the U.S. equity market, and the currency market. From purely the standpoint of information accessibility, ADR issuers are likely to time their issues or set their amounts with respect to the conditions of the home equity market and/or currency market, with which they are more familiar. On the other hand, issuers typically employ the assistance of U.S. investment banks, and therefore they may be well-informed about the U.S. equity market. This is largely an empirical issue. Generally, our empirical results are mixed, but there is somewhat stronger evidence for the U.S. equity market being more important when setting the issue amount. There is also evidence that suggests regulations having influences on such activities.

Abstract:

The last few decades have been a very exciting period in thedevelopment of micro-electronics and brought us to the brink ofimplementing entire systems on a single chip, on a hithertounimagined scale. However an unforeseen challenge has croppedup in the form of managing wires, which have become the mainbottleneck in performance, masking the blinding speed of activedevices. A major problem is that increasingly complicatedeffects need to be modelled, but the computational complexityof any proposed model needs to be low enough to allow manyiterations in a design cycle.

This thesis addresses the issue of closed form modelling ofthe response of coupled interconnect systems. Following astrict mathematical approach, second order models for thetransfer functions of coupled RC trees based on the first andsecond moments of the impulse response are developed. The2-pole-1-zero transfer function that is the best possible fromthe available information is obtained for the signal path fromeach driver to the output in multiple aggressor systems. Thisallows the complete response to be estimated accurately bysumming up the individual waveforms. The model represents theminimum complexity for a 2-pole-1-zero estimate, for this classof circuits.

Also proposed are new techniques for the optimisation ofwires in on-chip buses. Rather than minimising the delay overeach individual wire, the configuration that maximises thetotal bandwidth over a number of parallel wires isinvestigated. It is shown from simulations that there is aunique optimal solution which does not necessarily translate tothe maximum possible number of wires, and in fact deviatesconsiderably from it when the resources available for repeatersare limited. Analytic guidelines dependent only on processparameters are derived for optimal sizing of wires andrepeaters.

Finally regular tiled architectures with a commoncommunication backplane are being proposed as being the mostefficient way to implement systems-on-chip in the deepsubmicron regime. This thesis also considers the feasibility ofimplementing a regular packet-switched network-on-chip in atypical future deep submicron technology. All major physicalissues and challenges are discussed for two differentarchitectures and important limitations are identified.

Abstract:
Yes
Accurate time perception is critical for a number of human behaviours, such as understanding speech and the appreciation of music. However, it remains unresolved whether sensory time perception is mediated by a central timing component regulating all senses, or by a set of distributed mechanisms, each dedicated to a single sensory modality and operating in a largely independent manner. To address this issue, we conducted a range of unimodal and cross-modal rate adaptation experiments, in order to establish the degree of specificity of classical after-effects of sensory adaptation. Adapting to a fast rate of sensory stimulation typically makes a moderate rate appear slower (repulsive after-effect), and vice versa. A central timing hypothesis predicts general transfer of adaptation effects across modalities, whilst distributed mechanisms predict a high degree of sensory selectivity. Rate perception was quantified by a method of temporal reproduction across all combinations of visual, auditory and tactile senses. Robust repulsive after-effects were observed in all unimodal rate conditions, but were not observed for any cross-modal pairings. Our results show that sensory timing abilities are adaptable but, crucially, that this change is modality-specific - an outcome that is consistent with a distributed sensory timing hypothesis.

It would led to muuual fund performance evaluation incorrectly , so, we must use Transfer Function to improve traditional method. In addition, the study use holding- stock ratio of mutual fund to evaluate market- timing performance . Taking advantage of Causality (Granger;1969),if series X Granger cause series Y , I meant that series X leading series Y. This study made use of two serieses-mutual fund holding-stock ratio and market return to evaluate market-timing performance of mutual fund . If , mutual fund holding-stock ratio series leading market return , we firmly believed the mutual fund handing good market timing performance, conversely, it would not . The conclusions of the study listed below: 1. In Transfer Function, only Capital Small and Medium Cap Fund have significant selectivity in 13 closed mutual funds, and 8 mutual funds had, too , in 37 opened mutual funds . In market-timing performance , grand total 11 opened mutual funds significant. 2. In Causality test , only Grand Pacific Fund , have significant market-timing performance in 13 closed mutual funds , and 8 mutual funds had ,too, in 37 opened mutual funds. 3. In 50 stock mutual funds. Only 2 mutual funds have good market- timing and selectivity performance under Causality test and Transfer Function test.
