Time keeping in myriad networks : theories, solutions and applications
… sensor networks make extensive use of a common time reference. In this work we address the problem of time dissemination in a packet switched network when the nodes are NOT generally all connected to an accurate, external time reference source. We thoroughly analyze Network Time Protocol - …

Exploring the role of Gastrin-Releasing Peptide Neurons in Circadian Time-Keeping of the Suprachiasmatic Nucleus
… organisms predict, and thereby adapt to, solar time, ensuring efficient use of energy and resources. In mammals, circadian rhythms are present in practically every cell of the body and are synchronised by a master clock, the hypothalamic suprachiasmatic nucleus (SCN), which provides internal …

Complex Time-Keeping in Honey Bees: a Study of the Subset of Foragers Maintaining Multiple Time-Memories.
… state that foragers are active at only 1 time of day. It has been shown that a few foragers can be trained to forage at multiple times of day and at many locations. The purpose of the current study was to further investigate the phenomenon of foragers maintaining multiple …

Changing the High School Core Literature
… book rooms. Has the core literature changed over time with changing demographics? The review of the literature established the existence of a core literature, and that most high school students read from a fairly small list of books. The literature review reveals that students are not happy with …

Synchronization in Coupled Opto-thermal Silicon MEMS Limit Cycle Oscillators
… widely used in MEMS sensors, actuators, and time-keeping devices, and the use of a third-order model to give numerical and theoretical boundaries for self-synchronization, entrainment, and bistability.

Modulation of plant growth by day length dependent regulation of the TOR signaling pathway
… depends on the circadian clock, an internal time keeping mechanism that informs the plant of day length duration (photoperiod). The TOR (Target of Rapamycin) kinase pathway is a central hub where cellular energy levels are perceived and translated into specific growth responses across …

Empire's metropolis : money time & space in Colonial Bombay, 1870-1930
… and telegraph networks, standardisation and time-keeping, land acquisition and valuation, cadastral surveying and property registration, and the urban built environment. From the perspective of the colonial city, the history of these formations looks less like the smooth unfolding of singular …

The vampire inside my camera: an exhumation of gender, monstrosity and queer worldmaking through photography and video
… the limits of heteronormative structures of time-keeping. They break down how and why queer people may use troubled temporality and fluid depictions of gender to imagine utopian futures and queer worlds. This is pinpointed in the horror genre of film and various contemporary artforms that …

The use of wait-time as a conversational management strategy in second-language conversations
… commonly employed is the use of pauses to buy time keeping conversational channels open, organize thoughts, or search for a suitable response. This study described and compared these pauses, called wait-time, as they were used with other conversational management strategies by first- and …

[Urban] anchoring of Retreat Road: The contribution of a [transverse connector] into an urban development corridor
… of Retreat Road seems to have been frozen in time. The awkward geometry of the connection of Retreat Road to Main Road is one of the main causes of this stagnation. To facilitate the flow of energy, this dissertation proposes the realignment of Retreat Road, thus giving birth to a New Retreat …

Terrible timing: The causes and consequences of problematic work schedules
… stemming from volatile customer demand while keeping labor costs low, organizations in a host of industries frequently adjust when work occurs without taking employee input into account. The practices they use to do so often produce problematic schedules, or unstable and unpredictable hours …

Modeling the TDEM response for a lateral change in conductivity
… downwards and outwards through the earth in time, and is defined by the following parameters: a current amplitude, a horizontal expansion velocity and a vertical or downward velocity. The influence of the conductivity and layer thickness are investigated and it is found that the parameters of …

Modelling and Analysis of Resource Management Schemes in Wireless Networks. Analytical Models and Performance Evaluation of Handoff Schemes and Resource Re-Allocation in Homogeneous and Heterogeneous Wireless Cellular Networks.
… extra demands on system capacity. At the same time, keeping Quality of Service (QoS) at an acceptable level is a critical concern and a challenge to the wireless network designer. In this sense, performance analysis must be the first step in designing or improving a network. Thus, powerful …

Human factors and cultural influences in implementing agile philosophy and agility in global software development
… processes used, and achieve targets relating to time, budget and quality. In the software industry, several software methodologies have been used to address software development problems; however some of these processes may be too bureaucratic. The Agile Alliance formed in 2001, sought to address …

Social Authority and the Urban Environment in Nineteenth Century Cork

Application of polymerization-based amplification in point-of-care diagnostics
… results that must be read within a specified time interval to ensure their validity. In many instances, a user has to wait several minutes for the color to develop. Moreover, the result can be interpreted incorrectly because of low visual contrast. Therefore, a colorimetric detection …

Interlocking mechanisms regulating the circadian clock response to DNA damage
… an endogenously generated and self-sustained time-keeping system that oscillates with a periodicity of about 24 h, namely the circadian clock, that help them adapt to daily environmental changes. Mammalian circadian rhythms are generated and maintained by transcription-translation feedback …
