Approaches for Handling Time-Varying Covariates in Survival Models
Survival models are used in analysing time-to-event data. This type of data is very common in medical research. The Cox proportional hazard model is commonly used in analysing time-to-event data. However, this model is based on the proportional hazard (PH) assumption. Violation of this assumption …

Minimizing average handling time in contact centers by introducing a new process: Rowan Support Desk case study
… challenges that a call center often faces in handling requests are studied to identify key bottlenecks in the process of handling requests. Rowan University support desk is used as a case study. The focus of this study is on over-extended unsolved requests under set of specific constraints. …

Scanning-group-size effect in flocks of house sparrows : quantifying the contribution of competition and anti-predatory vigilance
… individual levels of scanning decrease while time spent feeding increases. Traditionally, anti-predatory considerations provide the preeminent explanation for this scanning-group-size effect, but contest and scramble competition could also account for the results. The anti-predatory hypothesis …

Oystercatchers and cockles : a predatory-prey study
… The profitability (flesh eaten per minute handling time) of cockles increased with their size. According to optimal foraging theory, these larger ones should therefore have been preferred, and this proved to be so. The rate at which oystercatchers ate cockles followed a type II functional …

The impact of system features on call centre agents' job performance and on their service delivery
… greatest impact of these factors was on average handling time (AHT) and 'not ready' time.

An analysis of alternative methods for loading provisions aboard AOEs 1 and 2
… present ship characteristics do not provide for handling and stowage of palletized provision cargo . Significant savings in material handling time and cost can be realized from handling cargo in palletized units. A comparison is made between the present handling procedure on AOEs 1 and 2 and five …

Time series forecasting with recurrent neural networks
Time series, such as demand trends, stock prices, and sensor data, is an essential data type in our modern world. Over the years, many models such as Exponential Smoothing and ARIMA are developed to make forecasts on time series. Recently, Recurrent Neural Networks (RNN) is gaining traction in the …

EFFECTS OF ALTERNATIVE PREY AS A BUFFER TO PREDATION OF CHANNEL CATFISH (ICTALURUS PUNCTATUS) BY LARGEMOUTH BASS (MICROPTERUS SALMOIDES)
… and compared order of ingestion, ingestion time, percent of successful strikes, and time spent chasing each prey species. We also presented the three species in a jar study that standardized position in the water column as well as in a net-pen study. The order of ingestion was suggestive of …

An improved chip-level test generation algorithm
… to select alternative solutions. A method for handling time in absolute, rather than relative, terms is discussed. Comparison of run times for the improved algorithm against those obtained by the previous method is made to demonstrate the speedup. Suggestions for incorporating the algorithm …

Research on objective speech quality measurements
… as across coders. (3) While PESQ is effective in handling time shifts that occur during silence, it does not seem as effective when such shifts occur during speech. (4) A simple extension of PESQ can evaluate wideband speech as well as it evaluates narrowband speech. (5) When clean speech is used …

Response of the Ozark Zigzag Salamander (Plethodon Angusticlavius) to High and Low Level Threats
… prey, probably because they required more handling time than low-calorie prey. Salamanders consumed fewer prey under high levels of threat but salamanders exhibited intermediate foraging levels under low levels of threat, which were substrate markings from a five-lined skink (Eumeces …

Assembly lead time reduction in a semiconductor capital equipment plant through improved material kitting
… plant, with an aim to reduce the production time of their longest lead time module. Preliminary analysis was done by observing the assembly and test operations on the production floor, and material handling operations at the warehouse. Detailed time studies were then performed on the assembly …

Market orientation of frontline employees and its impact on service quality and productivity within the South African contact centre industry
… one of the productivity indicators - Average Handling Time. Counter to expectation, the components of service quality were not found to be negatively correlated with productivity. This finding contradicts the literature that argues that service quality and productivity are often in conflict, …

Optimising calcium phosphate cement formulations to widen clinical applications
… in temperature, upon implantation, increasing handling time during surgeries; (3) incorporating therapeutic molecules to eliminate secondary surgeries following infectious diseases; (4) to enhance osteointegration of CPC’s by synchronising the degradation to natural bone formation. Results …

Habitat partitioning by sparrows along an elevational gradient
… the profitability of seeds (seed mass ingested / handling time) ranked similarly among sparrow species suggesting that species should have similar distributions. Also, species can apparently forage profitably outside of their customary habitats. Several measures of food availability suggested that …

HIDE AND SEEK: AN EXPLORATION OF ANTIPREDATOR AND PREDATOR AVOIDANCE MECHANISMS IN ORTHOPODOMYIA SIGNIFERA IN RESPONSE TO PREDATION FROM TOXORHYNCHITES RUTILUS
… <em>Or. signifera</em> had significantly longer handling time and fewer 2<sup>nd</sup> strikes in comparison with <em>Ae. albopictus</em>. The third hypothesis was inconclusive as the results could indicate a physical or chemical defense.</p>

The role of seed attributes in eastern gray squirrel foraging
… evidence supporting the Janzen-Connell and handling time hypotheses. From an economic perspective (chapter 3), I found that eastern gray squirrels are homogenous with respect to their preferences for seed attributes, which is likely due to natural selection favoring caching of specific seeds …

The occurrence and distribution of microplastics in surficial sediments and fish in a South African reservoir
