Abstract:

Traditionally a large role has been attributed to the spread of clocks and watches in fostering a ‘modern’ awareness of time. Yet, little research is available that empirically enables signs of growing time awareness to be linked to the distribution of time-keeping devices. In this article both these phenomena are brought together using two independent sets of evidence that permit the hypothesis that clocks and watches contributed to a heightened consciousness of time to be tested. While the ownership of clocks and watches was socially skewed, highly gendered and unevenly distributed over time, time awareness – as exemplified throughout numerous court cases – was essentially none of these.

Abstract:

In 1572 Robert Dudley gave to his queen a tiny clock set in a bracelet, an object scholars believe to be the first wristwatch. While Dudley’s gift to Elizabeth i was striking in its innovation, it was not the only timepiece he or those in his circle gave her. Using the New Year’s Day “Gift Rolls,” only recently collected from disparate archives and transcribed from manuscript by Jane Lawson, I establish that Dudley and those associated with him turned to this particular form of gift more often than other Elizabethan courtiers. Using theories of gifting I go on to argue that courtly gift exchanges involving elaborate private clocks and watches allowed Dudley and his circle to suggest their unique usefulness to Elizabeth i by offering her ways to imagine their service and her sovereignty.

Abstract:

75Au25Cu was the basic rosy gold alloy for jewelry, but it had no good brightness and was prone to tarnish and darken. This paper modified this basic alloy through multiple elements and less (micro) alloying, and measured its color and discoloration-resistance. The results showed that small amounts of zinc plus trace of silicon and cerium helped to improve the color and discoloration-resistance of the alloy, the initial colorimetric values fell in between 5N-18 standard alloy and 75Au25Cu basic alloy, while the brightness reached nearly 86, implying that the color was superior to the requirements of EN28654:1993 and ISO8654:1997. Moreover, the test alloy had better preferable resistance to darkening, discoloration and oxidation. All these performances indicated that the test alloy could meet the color requirement of rosy gold for ornaments such as clocks & watches and jewelries.

Abstract:

Over the last decades, fault injection attacks have been demonstrated to be an effective method for breaking the security of electronic devices. Some types of fault injection attacks, like clock and voltage glitching, require very few resources by the attacker and are practical and simple to execute. A cost-effective countermeasure against these attacks is the use of a detector circuit which detects timing violations - the underlying effect that glitch attacks rely on. In this paper, we take a closer look at three examples of such detectors that have been presented in the literature. We demonstrate four high-speed clock glitching attacks, which successfully inject faults in systems, where detectors have been implemented to protect. The attacks remain unnoticed by the glitch detectors. We verify our attacks with practical experiments on FPGA.

Abstract:

In modern times, with the development of industrialized society and the invention of clocks and watches, people have become more and more concerned about institutionalization, and higher education time and space have also shown the characteristics of institutionalization. In modern times, educational informatization has brought challenges and opportunities for educational reform and development. The vigorous development of education informatization has also produced changes in higher education spatiotemporally. For example, the rise of catechism and online learning, the importance of fragmented time, the development of space toward virtualization, and the expansion of interactive space for interpersonal interactions. In addition, the enrichment and sharing of educational materials, the informatization, and big data of educational management also contribute to the improvement of time efficiency and optimization of time structure in higher education. With the background of education under the new normal, this paper briefly analyzes the current situation of education informatization construction in colleges and universities from the perspective of education managers, and addresses the current situation and problems of teaching management informatization construction, such as organizational structure dominated by pyramidal functional departments, inefficiency, inability to connect work, difficulty in work gap, difficulty in horizontal coordination, and closed information. A work breakdown structure (WBS) based project management theory and work structure decomposition method are proposed. This paper finds that the improved association rule mining algorithm can improve the efficiency of teaching management practice in colleges and universities by more than 14.58%, which is an important reference value for college management informatization.

Abstract:

Watches are wearable devices that support human activities as timepieces. There are two types of watches based on their source driving energy: the quartz type, which uses a battery, and the automatic mechanical type, which uses a mechanical mechanism to convert the kinetic energy obtained when the clock is used as the energy to drive the hands. Automatic mechanical type watches have a time limit of 48 hours or two days until the energy turns off and the time stop. Therefore, a watch winder is needed to make movements to keep the automatic watch running while not in use. So, users can use their watch again without the need to adjust the time, date and other functions. The watch winder produced in this study employs a stepper motor that is controlled by an ESP32 microcontroller via a ULN2003 motor driver integrated circuit (IC). This type of stepper motor is used because it has a high rotor rotation precision to prevent the clock from over-winding problems. This watch winder device also has a watch condition monitoring feature through application-based temperature and humidity parameters. Users can monitor the condition of their watch and control the dial of the watch winder’s modules through the integrated application.

Abstract:

Comparisons were made between a commercially available, solar-activated mist control device (Weather Watcher®) and time clocks to determine their relative effectiveness, usefulness, and water-use characteristics on a greenhouse mist propagation bench. Coleus cuttings produced more roots per cutting and had greater average root lengths under Weather Watcher-controlled mist than those cuttings on a mist bench controlled by time. Paulownia cuttings produced the same number of roots under solar- or time-activated mist; however, the average root length was greater under Weather Watcher control. Mist benches controlled by the Weather Watcher used only one-third the water used by benches controlled by a time clock.

Abstract:

Many of European clocks in the Beijing’s Palace Museum (Gugong) were made in second half of the 18th century, by the Qing Emperor Qianlong’s governing (1736–1795), when an exotic “Chinese style” (chinoiserie) in the decorative arts was at its height. The research methodology proposed below, which combines art history and cultural analysis, allows us to see, that the Palace Collection’s mix determined evolution of the clock’s industry in China and some European lands, who took part in the international clock and watch market. In forms and decor of Chinese clocks the 18th century were reflected the change of European market. Together with western mechanical clock, being at the same time scientific device and work of decorative art, the European styles system was by ritual participation admitted in China. В статье показано, что западная часовая коллекция Цяньлуна (1736–1795), явившаяся первым в империи Цин (1644–1911) собранием произведений европейского искусства, связана с художественным рынком и феноменом шинуазри. Предложенная ниже методология, сочетающая искусствоведческий и культурологический подходы, позволяет увидеть, что состав этой коллекции повлиял на развитие производства механических часов в самом Китае и западных странах — участницах международного рынка искусств XVIII века. Собирательство механических хронометров в государстве Цин было обусловлено ритуализацией часов, устранившей проблему дуализма китайского и западного начал в цинской культуре и искусстве.

The results showed that: (1) Customers were quite satisfied with the service quality of wall clocks. (2) The purpose of this product management is to present a design with a new concept which is expected to improve the innovation climate in this industry. Studies and analyzes conducted in (1) this research include conducting interviews in detail, analyzing parts and materials, material analysis producing data, namely a choice of materials that are deemed appropriate for use in the product. (2) The result of product management is a wall clock design made of wood with a design that can be adjusted to the desires of consumers and there are still other product developments according to the results of previous studies and analyzes. Wall clocks are an important component in supporting daily activities, even though you are equipped with a personal watch whose price may reach millions of rupiah, but have we ever carried out activities without looking at the wall clock. Actually you also need to know if we pay attention to its shape, wall clocks can also add to the aesthetic value of a room. The simple concept is how wide of the wall you want to install the clock on.

Abstract:

Abstract Objective: The present study examines whether individuals who regularly wear a watch will perform better than those who do not on The Clock Drawing Test (CDT) within a memory disorder clinic population. Method: Data from 69 memory disorder clinic patients was utilized, ages 59-94 (M = 80.45, SD = 7.231; 52% female). Participants were included in this study if they had a diagnosis of cognition within normal limits, mild cognitive impairment, or unspecified neurocognitive disorder. Dementia diagnoses were excluded due to the potential impact of more severe cognitive dysfunction on task performance. Patients’ scores on the CDT and responses to questions regarding watch wearing were obtained as part of a brief neuropsychological evaluation. Regular watch wearing was defined by those who responded affirmatively to the question “do you regularly wear a watch?”; individuals reported wearing a watch at least 2 times per week, with the majority (N=30) reporting wearing a watch 5 or more times per week. Results: The 38 participants who wear a watch regularly (M=9.13, SD=.811) performed significantly better on the CDT compared to the 29 participants who do not (M=8.83, SD=1.1441), t(65) = 4.210, p=.044. Similarly, those who wear a watch regularly (M=.85, SD=.812) made significantly fewer errors on the CDT compared to those who do not (M=1.17, SD=1.17), t(65)=4.101, p=.047. Conclusion: Results indicate that individuals who regularly wear a watch perform better on the CDT, making fewer errors than those who do not. This finding might suggest increased planning and organization skills in those who wear watches regularly.

Abstract:

Research has been going on for a lengthy time on digital clocks but with restraints to auto-updating based totally on location. The objective of the paper is to produce a portable and accurate auto-update digital watch (clock) that shows the real time and the current location of the user with the aid of crystal oscillator to generate clock pulses which interfaced with the GPS modules with organic light-emitting diode (OELD). The system was able to automatically update the co-ordinate of locations whenever the user moves from one place to another, It also auto-update time whenever the battery is removed and reinserted or when switched OFF and then switch ON after sometime. It also eliminate the stretch associated with time adjustment whenever the battery is down and replaced or when the watch is switched OFF and then ON. It performed satisfactorily and as a result, the system can be adapted and integrated to the new technology of modern watch as it can be adopted by the user to locate his/her position at any point in time.

Abstract:

The article highlights some episodes of the rich labor activity of the representatives of the firm “Pavel Bure”. In particular, the work performed by the masters of the firm to repair and replace clocks and clock mechanisms in the South Coast estate of the Empress “Livadia” in 1877–1879 on the eve of the forthcoming visits to the estate of representatives of the imperial family. The history of the enterprise up to the beginning of the XX century is briefly characterized. The reasons why the services of this company were used to repair clocks in the estate “Livadia” are noted. Also in the material there is information about the amount requested by the masters for the performance of the required amount of work. The article is replete with data on the working and living conditions of the watchmaker during his orders at the “Livadia” estate. Among other things, it characterizes the master's daily life and other interesting aspects of his residence and work at the estate. For instance, there is data on the materials used during the repair work and, in general, on the amount of work performed by the master during each of his business trips to the estate. In the final section, the article concludes with data on how the auction of unrepairable clocks and watch move-ments was organized.

Abstract:

A través del estudio de Watchmen en sus 3 formatos: comic, película y serie, se plantea una interlocución con el psicoanálisis, a fin de extraer lecturas que permiten pensar la época, caracterizada por la amenaza de cataclismos y conflictos bélicos a gran escala, en el marco de una pandemia generalizada con su consecuente impacto sobre la población. La fantasía del fin del mundo, presente en Watchmen, se sostiene en un denominador común, trans-histórico: el objeto de goce, singular para cada sujeto y, por lo tanto, inseparable de su propia historia. Por un lado, se plantean los efectos segregativos a los que puede conducir el objeto en tanto kakón. Por el otro, se evidencia cómo la serie conmueve las entrañas del campo reactivo al cual ha sido circunscrito el trastorno por estrés post-traumático (TEPT). Como contrapartida, se sitúan dos conceptos claves ante la pérdida del objeto: de satisfacción, en el trauma en sus dos tiempos, y de amor, en el duelo, que nos permitirán volver a una lectura de la época, al constituirse ella, no sólo como impacto, sino principalmente como efecto de las narrativas singulares de la vida de las personas.

Abstract:

The work is devoted to the development of a prototype of an electronic clock based on a 176 series microcircuit. To create a prototype, an integrated circuit K176ID3, LEDs (VD1, VD2, VD3, VD4, VD5), an indicator (VD6), momentary buttons (KK, KM, KR , KN), capacitors (C1 – 47 pF, C2 – 1500 pF, C3 – 0.01 μF), resistors (R1 – 9.1 kΩ, R2 – 1 mΩ, R3 – 100 kΩ, R4 – 100 kΩ, R5 – 1 kΩ; R6 – 100 kOhm). The stages of assembling a prototype are described in detail. In the course of this work, a circuit was made on microcircuits of the K176 series with counters – K176IE12, K176IE13 and a decoder – K176ID3. The K176IE12 microcircuit generates the necessary control signals (including, for the operation of the indication and minute pulses). The K176IE13 counter counts minute impulses and performs the function of an alarm clock. From the outputs of this counter, the time readings are displayed on the indicator through the K176ID3 decoder. The role of cathode switches is performed by logic inverters K155LN2 (with an open collector). The K176IE12 microcircuit consists of three parts.

Abstract:

Abstract Introduction A critical obstacle for circadian medicine is the lack of feasibility in measuring circadian phase in the clinic. Existing tools such as assessment of dim light melatonin onset (DLMO) are too resource intensive, especially in populations with extreme circadian disruption such as night shift workers. Recent studies have demonstrated the validity and feasibility of estimating circadian phase via mathematical modeling data collected with wearable technology. However, these studies have mostly relied on research grade devices (e.g., actigraphs) that have limited scalability. In this work, we validate the use of a consumer wearable (the Apple Watch) to predict DLMO in a population of night shift workers. Methods A sample of 21 fixed-night shift workers wore an Apple Watch for two weeks before completing DLMO in the lab. DLMO was assessed via hourly salivary melatonin samples collected in dim light (< 10 lux) for a period of 24 hours. Activity data was used as input into the Hannay model of the circadian clock to produce a predicted DLMO, which was then compared to in-lab DLMO. Results Model predictions of DLMO showed high correlation with in-lab DLMO, with a Lin’s concordance correlation coefficient (CCC) of 0.81, with a mean absolute error (MAE) of 2.10. This was comparable to the previously published validation using research grade actigraphy (CCC = 0.70; MAE = 2.88). Conclusion This study is the first to provide evidence suggesting that estimates of circadian phase using the Apple Watch have comparable validity with research grade actigraphy. These results have significant implications for the scalability of circadian medicine, particularly as consumer-based wearable technology is already commonplace. Apple Watches are also the most common consumer-based wearable device. Future research should extend findings to other wearable devices, especially devices at a lower price-point to increase accessibility. Support (if any) Support for this study was provided from the American Academy of Sleep Medicine Foundation (245-SR-21) awarded to Dr. Philip Cheng.

Abstract:

Currently a decubitus clock is a device used in hospitals to monitor the patient's position in bed. In addition to preventing pressure sores, the decubitus watch can improve patient comfort and recovery by allowing medical staff to monitor and adjust positions more frequently and effectively. Following this premise, this project is inspired by the low-cost Lowthian watch model, using parts built in a 3D printer, arduino uno, buzzer, leds, protoboard, acrylic box and stepper motor. In addition to improving the physical structure, an easy-to-understand hygienic and practical model was introduced. In the end, the project results in an automated profile that contributes to the learning process related to innovation, stimulating creativity through the insertion of these resources in the daily routine of the hospital environment.

Abstract:

Human experience of time exhibits systematic, context-dependent deviations from clock time; for example, time is experienced differently at work than on holiday. Here we test the proposal that differences from clock time in subjective experience of time arise because time estimates are constructed by accumulating the same quantity that guides perception: salient events. Healthy human participants watched naturalistic, silent videos of up to 24 seconds in duration and estimated their duration while fMRI was acquired. We were able to reconstruct trial-by-trial biases in participants’ duration reports, which reflect subjective experience of duration, purely from salient events in their visual cortex BOLD activity. By contrast, salient events in neither of two control regions–auditory and somatosensory cortex–were predictive of duration biases. These results held despite being able to (trivially) predict clock time from all three brain areas. Our results reveal that the information arising during perceptual processing of a dynamic environment provides a sufficient basis for reconstructing human subjective time duration.

Abstract:

The environmental light–dark cycle is one of the most reliable rhythmic signals, and many organisms have evolved a circadian (circa diem, ‘about a day’) system to co-ordinate biological processes with this predictable environmental change. These rhythms are endogenous and persist even in constant conditions, the light–dark cycle serving to synchronize these rhythms precisely to 24 hours. Genetic approaches have proved invaluable in increasing our understanding of the circadian clock. The ability to isolate a mutant with a defect in a rhythmic process is a very powerful method, which depends on no prior assumptions about the biological process under investigation. Consequently, Drosophila and the mouse have become the most powerful genetic models to study circadian rhythms in animals. The one alternative vertebrate genetic model system to the mouse is the zebrafish (Danio rerio).

Abstract:

In the era of globalization, the development of the fashion world with a variety of models and designs is increasing very rapidly. This condition has triggered a cycle of changing the style of dress that is dynamic, especially in the watch fashion industry. In addition to referring to the time the watch can also give a distinctive impression to the wearer. The sampling method is carried out using non probability sampling techniques by means of purposive sampling. By wearing a watch we can look more elegant. With a fairly large number of competitors, triggering the clock shop to focus on product quality and price competition, but the competition is not enough because there are still many aspects that can be used by the clock store to win the competition and become a market leader. Innovative strategies are needed to survive and win the competition, including strategies to improve service quality and rearrange Servicescape in this regard with regard to customer satisfaction and customer loyalty.

Abstract:

The changing use of the clock metaphor serves as a helpful contrast medium to highlight the different concepts of the body-soul-system between 1450 and 1750. This article first relates to the social, political and philosophical functions of the horologium. Then it outlines the different fields of discourse, in which the clock metaphor was mainly invoked. Finally, it examines the writings of a number of significant authors (Cusanus, Ficino, Descartes, Leibniz, Wolff, La Mettrie) with an eye to the evolution of the clock metaphor in various theological, metaphysical and physiological contexts. Surprisingly enough, the clock (or watch) initially represented the life-giving soul and human consciousness, before turning into the well-known symbol for the bodymachine, and in particular for its neurophysiological operations.

Abstract:

ABSTRACTThe aim of this qualitative secondary data analysis was to identify the metaphors women used to describe their anniversary of their traumatic births. The existing data set that was reanalyzed was from a phenomenological study of the anniversary of birth trauma. Metaphor identification procedure was the method used to identify 8 different metaphors from the women’s descriptions that provided a rich source of insight into their yearly struggles. These metaphors characterized the anniversary of traumatic birth as a great pretender, a lottery, a trigger, a clock watcher, a giant rubber band, a guilt trip, a sea of sadness, and bottled up anger.
