The experience of time is not fixed by a rigid mathematical measure, instead, it flows at vaying rates. There are certain occasions in which we would like to extend time with all our force, up to the limit of our stretched arms and further. Conversely there are moments which we'd like to last no more that the sparkle of a flash, but as we all have noticed, those are the longest in our life. How does the space that we inhabit influence on our perception of time? May we identify especial elements that contribute in one or other sense to accelerate or slowdown the time? It's said that time and space is an inseparable unity, as two aspects of the same thing. If this is so, then it also must be true that by shaping space in one way or another, we might influence the experience of time through it. Wouldn't it be delightful to believe that we may be magicians of time through manipulation of architecture? / Master of Architecture

Syftet med den här uppsatsen är att utföra de la Fuente et al:s (2014) experiment med priming av temporalt fokus hos arbisktalande individer med svenska som andraspråk. De frågor som undersöks är i vilken utsträckning de la Fuente et al:s temporalfokushypotes är generaliserbar till fler språkgrupper än spansktalande, vilka primingeffekterna blir hos individerna, samt vilka faktorer som inverkar på det temporala fokuset utöver primingen. Metoden är att återupprepa det experiment de la Fuente et al. gjort med spansktalande, genom att återutföra det på en grupp arabisktalande individer med svenska som andraspråk. Resultatet av föreliggande studies upprepning av de la Fuentes experiment på arabisktalande, visar att primingeffekterna uteblir, men att faktorer som vistelsetid och ålder inverkar påvisbart på tidsrepresentationen. Utbildningsbakgrund visar tendenser till att inverka på tidsrepresentationen. Ett temporalt fokus påverkbart av yttre stimuli går inte att påvisa i den här studien, varför delar av temporalfokushypotesen inte är generaliserbar till alla språkgrupper.

Execution time control is a technique that allows execution time budgets to be set and overruns to be handled dynamically to prevent deadline misses. This removes the need for the worst-case execution time (WCET) of tasks to be found by offline timing analysis – a problem that can be very hard to solve for modern computer architectures. Execution time control can also increase the processor utilization, as the WCET will often be much higher than the average execution time. This thesis describes how the GNU Ada Compiler and a bare-board Ravenscar run-time environment were ported to the Atmel AVR32 UC3 microcontroller series making the Ada programming language available on this architecture for the first time, and an implementation of Ada execution time control for this system that supports full execution time control for interrupt handling. Usage patterns for this brand new feature are demonstrated in Ada by extending the object-oriented real-time framework with execution time servers for interrupt handling, allowing the system to be protected against unexpected bursts of interrupts that could otherwise result in deadline misses. Separate execution time measurement for interrupt handling also improves the accuracy of measurement for tasks. As a direct result of the work presented in this thesis separate execution time measurement for interrupts will be included in the forthcoming ISO-standard for Ada 2012. While the implementation of execution time control is for the Ada programming language and the UC3 microcontroller series, the design and implementation should be portable to other architectures, and the principles of execution time control for interrupt handling applicable to other programming languages. Low run-time overhead is important for execution time control to be useful for real-time systems. Therefore a hardware Time Management Unit (TMU) was designed to reduce the overhead of execution time control. This design has been implemented for the UC3 and performance tests with the developed run-time environment shows that it gives a significant reduction of overhead. The memory-mapped design of the TMU also allows it to be implemented on other architectures.

Full-time employed and unemployed adults' life level of analysis future time perspective (FTP) and work level of analysis occupational future time perspective (OFTP) were evaluated to measure differences between FTP conceptualizations and the validity of OFTP in the work domain. A final sample of 304 full-time employed and 98 unemployed job seeking adults completed a self-report online battery including demographic, work history, FTP, work-related attitudes, and personality measures. Results found the three FTP conceptualizations [Carstensen and Lang Future Time Perspective Scale (CL-FTP); Zimbardo and Boyd Future Factor (ZBF); and Consideration for Future Consequences Scale (CFC] were differentially related to achievement striving and planfulness. The CL-FTP scale was weakly, significantly and not significantly related to the CFC and ZBF scales, respectively. In addition, results indicated OFTP had a significantly stronger relationship with chronological age than CL-FTP and OFTP added incremental validity beyond general CL-FTP in predicting work-related attitudes. Lastly, mean differences in CL-FTP and OFTP scores by employment status were obtained, indicating that OFTP may be susceptible to change via work characteristics. Further exploratory analyses and theoretical and practical implications of the current findings are discussed.

This essay offers a deconstructive approach to Nabokov´s Lolita. Critics have tended to treat space and time as distinct concepts in the novel: choosing to analyse the role of either one or the other, and even when considering both, examining them in isolation. It´s narrator, Humbert Humbert, however, implies that "time" and "spatial" terms are interchangeable in a way reminiscent of Einstein´s Theory of Relativity in which space-time is a continuum that is experienced relative to the individual observer´s own position in the universe. This essay therefore explores the possibility that Nabokov may have used Einstein´s concept of space-time relativity as a metaphor in Lolita. The essay looks first at the various ways in which the idea of relativity surfaces throughout the novel not just in relation to space and time, but also in its moral, cultural and historic forms. The roles of the Hour Glass Lake, Lolita´s sunglasses and Humbert´s car, three of the novel´s chief symbols, are then discussed in relation to its key elements: the notion of time dilation, the place of the observer and Humbert´s space-time bubble. It next concentrates on how the characters in the novel exemplify the roles of both observer and observed in a modern, self-centred and morally relativistic world. The final section argues that Humbert’s "madness" represents the most extreme consequence of his living in his own solipsistic bubble of space-time, or "dream vacuum" as he calls it.

Time-resolved electroluminescence has been primarily and widely applied in the field of optoelectronic devices and phosphor materials. Here we use the method to measure the response time and phase difference of green light-emitting diode. In our experiment, which is essentially dominated by pulsed signal from function generator¡Bhigh spatial resolution from laser scanning microscopic and phase-lock characteristic from lock-in amplifier to complete our experimental result. We are capable to detect relative carrier information within any point or any surface region from epi-layer of green light-emitting diode. Otherwise, the carrier transport of the sample is able to be observed through time-resolved characteristic measurement. Laser cutting would be beneficial for obvious phase-difference observation and mobility acquirement.

We transport the standard time signal by using the single-mode fiber (SMF) media through the synchronous optical network (SONET)/ synchronous digital hierarchy (SDH) data signal, in which the time signal generated from the atomic clock was inserted into the unused bytes in the overhead of the SONET/SDH OC-3 155 Mb/s frame. Based on the NIST MODEM architecture, which was developed by the National Institute of Standard and Technology in the States, the time transfer system is composed of the control unit of the OC-3 transceiver module and the time-signal transmiting/receiving unit. We design and fabricate the required time-signal transmitting/receiving circuits and the control and monitoring circuits. The personal computer (PC) can read/write and monitor the operation status of the optical transceiver module through the control circuit, and the 1-PPS (pulse per second) time signal can therefore be read/written from/into the transceiver module. The frequency stability of about 2.6E-16 within one day can be achieved for this 1310-nm optical-fiber-based time transfer system over a 35-km SMF link without using electronic regererator. Such stability performance is comparable with that of today¡¦s GPS-based time transfer system.

controllers for discrete-time systems and time-delayed systems. By using bilinear transformation and orthogonal transformation, earlier research results obtained in the continuous-time case are extended to discrete-time situation. The complete set of stabilizing PID controllers for the discrete-time systems is thus obtained. Moreover, this set remains to be a union of convex sets when one particular parameter is fixed. Thus a method to design robust and non-fragile digital PID controllers is proposed by following a similar design procedure for the continuous-time systems. In order to find the stabilizing controller set for systems with time-delays, the relationship between the Nyquist Criterion and Pontryagin’s theory is investigated. The conditions under which one can correctly apply the Nyquist Criterion to time-delayed systems are derived. Then, the complete set of stabilizing PID controllers for arbitrary order LTI systems with time-delay up to a given value is obtained. Furthermore, the stability issue of a system with fixed-delay is also studied and a formula which provides complete knowledge of the distribution of the closed-loop poles is presented. Based on this formula, stabilizing P and PI controller sets for the system with fixed-delay can be computed.

As the growth of multimedia communications involving digital audio and video, it is increasingly important for the MANET (Mobile Ad Hoc Network) routing protocols to simultaneously support both real-time and non-real-time traffic. MANET energy management should offer this support because devices are equipped with limited battery power. To achieve this end, we revise the Ad hoc On-demand Distance Vector (AODV) routing protocol to provide an energy management mechanism such that both real-time and non-real-time packets can be effectively transmitted. In the proposed scheme, real-time traffic uses higher transmission power to reduce transmission delay time and selects a shortest route with the largest minimum residual energy to avoid route break. The non-real-time traffic uses normal transmission power to save energy and chooses a proper shortest route with highest average residual energy to balance node energy consumption. The simulation results show that the revised AODV obtains lower average end-to-end delay and fewer energy-exhausted nodes comparing to the conventional AODV.
