Asynchronous Dialogue System

Nguyen, Keman, Andersson, Alfred · KTH Publication Database DiVA (KTH Royal Institute of Technology) · 2022

Conversations between the PC (player character) and NPCs (non-player characters) in conventional games are usually sequence-based. The NPC talks to a certain point before pending the player's input, sometimes consisting of several prepared actions displayed on the screen in order to advance the conversation. While this method does provide the ability to converse within video games, our study shows it lacks the immersiveness that asynchronously based dialogue provides in some scenarios. Interruptions occur in real-life conversations and may add to a more convincing interaction. In this paper, we present a novel dialogue system that incorporates interruptions alongside emotion, making it possible for different participants involved in the conversation to interrupt and speak over each other while also having lasting consequences. This approach improves conversational players' experience by increasing character believability and engagement. For illustration purposes, interruption was integrated into a text-based game encompassing two variations of the same scenario. The study involved playing both variations of the same game, one being a traditional sequence-based conversation while the other had a fluent dialogue which supports interruption both from the PC and NPCs. Eight students previously familiar with video game dialogues played both variations, half starting with the other version. Each test ended with a survey followed by an interview talking about the answers. Each test took 30-40 min.

Timed Asynchronous System Model

Flaviu Cristian, Christof Fetzer · 1997

We propose a formal definition for the timed asynchronous system model, we describe extensive measurements of actual message and process scheduling delays and hardware clock drifts that confirm that this model adequately describes current distributed systems built from networked workstations, and we give an explanation of why practically needed services, such as consensus or leader election, which are not implementable in the time-free asynchronous system model, are implementable in the timed model. 1 Introduction Depending on whether the underlying communication and process management services make interprocess communication by messages certain or not, distributed systems can be classified as either synchronous or asynchronous [7]. Communication certainty in a synchronous system means that any message sent by a correct process to a correct destination process is received and processed at the destination within a bounded time. This is achieved in practice by 1) using hard real-time s...

Large system asynchronous design

D.E. Johansen · 2002

A language is presented for the design of asynchronous logic circuits. The language offers effective syntax for specifying long-range interactions among signals remote from one another in the data pipeline. Problems specified in the language have a unique-state-coding implicit in their formulation. Solutions are fully interlocked and satisfy properties of liveness, safeness, and persistency. Features of the language are presented with two examples. One involves the design of an asynchronous 3:1 parallel multiplexer involving concepts of bundled data paths and control. The other illustrates the synthesis of self-timed data paths of a type described by T.E. Williams and M.A. Horowitz (1991).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

This paper presents concept and implementation of digital phase-location system, designed as a navigational aid for marine applications. The main feature of the proposed system is the ability to work in both synchronous mode, with one master station and set of slave stations synchronised with master, and in asynchronous mode with independent clocking of all stations.

Iteration in Asynchronous System

Ajitesh S. Baghel, Rakesh Kumar Katare · Zenodo (CERN European Organization for Nuclear Research) · 2024

ABSTRACTWe present a couple of traditional iterative strategies for unravelling straight comparisons; such routines are broadly utilized, particularly for the arrangement of substantial issues, for example, those emerging from the discrimination of direct fractional differential mathematical statements. We depict the iterative or backhanded systems, which begin from a rough guess to the genuine arrangement and if concurrent, infer a grouping of close estimates the cycle of reckonings being rehashed till the obliged precision is gotten.Keyword: asynchronous system, P-RAM, MPI, Parallel, Distributed, Interconnection network.

MODIFIED ASYNCHRONOUS CASCADE MACHINE SYSTEM

S. Sathiakumar, W. Koczara · Electric Machines & Power Systems · 1997

ABSTRACT The modelling of the modified asynchronous cascade machine system is done in order to study the features of such system under field-oriented frame of reference. The modified machine system has two stator windings and two sections of rotor winding on the same shaft One of the stator windings is connected to the ac network while the other winding is connected to an inverter capable of controlling power flow in both directions. This system can be operated in a wide speed range and both sections of the rotor winding can produce useful torque.

Managarm: A Fully Asynchronous Operating System

van der Grinten, Alexander, Słomiński, Kacper, Custers, Geert · Gesellschaft für Informatik (GI) · 2024

In this paper, we give an overview of the system architecture of Managarm, a free and open source operating system that is based on a microkernel. The goal of Managarm is to build a general-purpose OS on top of unprivileged drivers and servers that run in user space, while still providing extensive source-level compatibility with existing POSIX and Linux applications. To minimize context switches even when driving modern hardware that supports high degrees of concurrency, Managarm exclusively relies an asynchronous IPC mechanism that enables the submission of an arbitrary number of independent IPC requests before performing a context switch. Additionally, since existing POSIX and Linux applications are not always designed around asynchronicity, we provide a user level emulation of POSIX and Linux APIs. Our emulation is sufficient to run various Linux application, including modern desktop environments.

Ultrawideband asynchronous tracking system and method

Gross, Julia A., Dusl, John, Ni, Jianjun et al. · NASA STI Repository (National Aeronautics and Space Administration)

A passive tracking system is provided with a plurality of ultrawideband (UWB) receivers that is asynchronous with respect to a UWB transmitter. A geometry of the tracking system may utilize a plurality of clusters with each cluster comprising a plurality of antennas. Time Difference of Arrival (TDOA) may be determined for the antennas in each cluster and utilized to determine Angle of Arrival (AOA) based on a far field assumption regarding the geometry. Parallel software communication sockets may be established with each of the plurality of UWB receivers. Transfer of waveform data may be processed by alternately receiving packets of waveform data from each UWB receiver. Cross Correlation Peak Detection (CCPD) is utilized to estimate TDOA information to reduce errors in a noisy, multipath environment.

System state estimation with asynchronous measurements

Guido Cavraro · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 2023

The present disclosure provides techniques for estimating network states using asynchronous measurements by leveraging network inertia. For example, a device configured in accordance with the techniques of the present disclosure may receive electrical parameter values corresponding to at least one first location within a power network and determine, based on the electrical parameter values and a previous estimated state of the power network, an estimated value of unknown electrical parameters that correspond to a second location within the power network. The device may further cause at least one device within the power network to modify operation based on the estimated value of the unknown electrical parameters. The leveraging of network inertia may obviate the need for probabilistic models or pseudo-measurements.
