Assessing Maintenance and Management of Infrastructure Systems Using Citizen Reported Service Requests
… respond to real-time infrastructure system service disruptions and maintenance requests. Of the 200 or more cities that use 311, New York City's system is the largest, receiving more than 19.5 million citizen requests since 2010. Current citizen service requests made through 311 range from …

Illness models of relatives of African psychiatric patients : implications for a family-based service
This study explores the illness models and service requests of relatives of 30 African psychiatric patients. Relatives' perceptions of illness and expressed needs were elicited with a view to developing a more contextual understanding of disorder, and to obtaining an indication of interest in …

Delay, stability, and resource tradeoffs in large distributed service systems
… dispatching policies in large-scale distributed service systems, motivated by examples such as cloud computing facilities and multi-core processors. A canonical framework for modeling such systems is provided by a parallel queueing model with n servers, where service requests arrive …

eMicro: Real-Time Multi-Hop Access Control for Microservices with eBPF
… applications often comprise thousands of microservices whose interactions form complex request paths. Traditional inter-service access control restricts individual service-to-service requests, but fails to prevent multi-hop attacks, where each hop appears legitimate yet the overall path …

Quantitative modeling and analysis with FMC-QE
… In this new methodology, the hierarchical service requests are in the main focus, because they are the origin of every service provisioning process. Similar to physics, these service requests are a tuple of value and unit, which enables hierarchical service request transformations at the …

Distributed naming in a factored operating system
… for manycore and cloud computers. In fos, OS services are separated from application code and run on distinct cores. Furthermore, each service is split into a fleet, or parallel set of cooperating processes that communicate using messages. Applications discover OS services through a …

Automated discovery of performance regressions in enterprise applications
… performance tests. In a performance test, service requests with intensity similar to the production environment are pushed to the applications under test; various performance counters (e.g., CPU utilization) are recorded. Analysis of the results of performance verification is both …

Ecosystem services of urban amenity greenspace and the impact of future climate and socio-economic change
… is a lack of information regardingecosystem services associated with urban environments. This research measures nineecosystem services delivered by urban amenity greenspace and projects responses to futurechallenges.Botanical and environmental data relating to five regulating services and …

Analytics for Healthcare Operations: Machine Learning to Improve Emergency Department Patient Flow
… a significant increase in demand for hospital services. Overcrowding in the ED and high utilization of inpatient floors are symptoms of this increase in demand. Chapter 2 shows that data available at the time of an inpatient bed request can be used to prospectively identify ED patients who are …

A source-destination based dynamic pricing scheme to optimize resource utilization in heterogeneous wireless networks
… because callers and not callees pay for network services, and resources used by callers and callees are the same for symmetric services. For example, application of dynamic pricing does not deter a callee located in a congested cell from receiving a call, which originates from a caller located in …

Interactivity And User-heterogeneity In On Demand Broadcast Video
… non-periodic multicast setting, users make video requests to the server; and it serves them according to some scheduling policy. In a periodic broadcast environment, the server does not wait for service requests. It broadcasts a video cyclically, e.g., a new stream of the same video is started …

Applications of agent architectures to decision support in distributed simulation and training systems
… channels with specified ontology and semantics. Services can be requested and responses with results received over such communication modes. Both traditional (functional) parameters and nonfunctional (e.g. QoS, deadline, etc.) requirements and captured in service requests.

Supporting the operational performance management of public service systems during slow-onset disasters
… which diversify amounts and types of public service needs. Understanding the varying needs of communities that rely on government services helps decision-makers allocate limited resources properly during crises to maintain effective, efficient, and equitable service provision across the …

Data-driven System Design in Service Operations
The service industry has become an increasingly important component in the world's economy. Simultaneously, the data collected from service systems has grown rapidly in both size and complexity due to the rapid spread of information technology, providing new opportunities and challenges for …

A dynamic web interface to a remote robot evaluated with a robotic telescope.
… permits, the robot processes the observation requests submitted by users via the Internet, operating all the hardware including the dome, telescope mount and cameras. The question of how to enable a content rich high quality dialogue between one robot and thousands of users is explored and …

Dynamic service orchestration in the IP multimedia subsystem
… in a massive uptake of different communication services. An ever-increasing number of users are utilising rich multimedia services, and are both consuming and producing user generated content. This rapid growth in bandwidth and complexity has resulted in challenges for the previous architectures …

Improving Throughput and Efficiency for WLAN: Sounding, Grouping, Scheduling
… while accommodating the different Quality of Service (QoS) levels. We evaluate the possibility of regulating QoS through prioritizing the users in OFDMA-based WLAN. We define a User Priority Scheduling (UPS) criterion that strictly guarantees service requests of the spectrum and time resources …
