Повний текст джерелаFörstärkningsinlärning (reinforcement learning) är ett paradigm inom maskininlärning. I detta paradigm får inte agenter (de som ska lära sig) instruktioner på vad de ska göra, istället måste de självständigt utforska och pröva sig fram för att lära sig ett beteende som maximerar någon numerisk signal. Förstärksningsinlärning har dock flera utmaningar och problem, en av dessa är tränings- tid. Det kan krävas miljontals träningspass för att agenterna ska bli duktiga på deras uppgift, något som är problematiskt då det är dyrt för många system att producera datan. Denna avhandling undersöker om det är fördelaktigt för agenter som lär sig leka kull, vad det gäller deras spelfärdighet och träningshastighet, om de tränas mot andra lärande agenter istället för icke-lärande agenter. För att undersöka detta så har agenter tränats att leka kull mot olika typer av motståndare och under träningen så har flera benchmarks utförts. Benchmarksen räknade hur många gånger jagarna fångat bytet under flera spelomgångar. Resultaten från benchmarksen visade att det är fördelaktigt både för spel- färdighet men också träningshastighet att agenter tränas mot andra lärande agenter. Träningen mot icke-lärande agenter påverkade som bäst inte resultatet och i värsta fall så försämrades både träningshastigheten samt spelfärdigheten.

Повний текст джерелаImmersive virtual environment can be used to bring both geographically distributed and co-located users to the same virtual place for collaboration. Compared to remote situations, co-located users collaborate in the same virtual world on top of a shared physical workspace. This collocation allows direct user communication and interaction without computer mediation which facilitates collaborative work. With the development of multi-user display and tracking technology, classical projection-based immersive setups (e.g. CAVE) can now support group immersion for co-located users by offering individual stereoscopic views without visual distortion. In this context, the coexistence of information from the virtual and real world, especially when users do not share a common spatial reference frame, provides users with a new kind of perceptual and cognitive experience. We are interested in how users perceive and communicate with each other to achieve a shared context for collaboration, and how we can broaden supported collaborative scenarios with more flexible viewpoint control.This PhD thesis mainly addresses perceptual and cohabitation issues that we identified in the aim of supporting safe and efficient co-located collaboration in immersive virtual environment. First, we conducted a case study to examine how perceptual conflicts would alter user communication and task performance. Second, we concentrated on the design and evaluation of appropriate navigation paradigms to allow individual virtual navigation while solving cohabitation problems in a shared limited physical workspace. At last, based on the results of previous studies, we designed a generic dynamic navigation model which integrates constrains from the physical workspace and also the virtual world to enable co-located collaboration in multi-user immersive systems

The objective of the study is to find an optimal inventory distribution in a retail three-echelon environment, consisting of a supplier, a DC, and stores. An inventory model is built by replicating the echelons' periodic, order-up-to-level policies with all echelons' transactions integrated. Network carrying cost is set as an objective function, while the store target service level and the store's minimum order-up-to-levels are set as constraints. A heuristic approach, that combines the optimization and simulation methods, is used to find the optimal inventory distribution. The results show that the optimal network carrying cost can be achieved by having low inventory and low service level at the DC. In addition, the impact of the echelons' deviations from the optimal policies as well as the impact of the upstream echelon's service disruptions on the other echelons confirms the interrelation between the echelons in the network. The analyses also illustrate that high target service level can be accomplished by keeping high inventory at the stores and the DC.

The demand for increased data availability and reliability of storage systems has contributed to the design and deployment of multi-node data storage clusters. This paper presents a simulator of one such multi-node, multi-machine cluster. The simulator is architected by extending the NetApp, Inc. 2-node cluster architecture to an N-node design. Data availability is provided by mirroring client requests to a subset of peers in the multi-node cluster. Using this simulator, this thesis explores the relationship between the number of peers that each node mirrors to and the overall mirroring latency. This thesis also explores the performance cost incurred when, in response to a mirroring request from a peer node, a node stores the mirrored data in nonvolatile storage before acknowledgment. Using a workload consisting of multiple write requests to different nodes in the simulator, this thesis finds that there exists a linear relationship between the number of mirroring peers in a cluster and the resulting mirroring latency. Experiments using this workload also reveal a 40% increase in mirroring latency when the mirroring requests are stored on peer nodes persistent storage as opposed to volatile memory.

Повний текст джерелаUn problema que se introduce con esta colaboración es un incremento en la heterogeneidad tanto de cómputo como de comunicación, aumentando la complejidad de dicho sistema lo que dificulta su uso.
El objetivo de esta tesis es lograr la reducción del tiempo de ejecución de aplicaciones, originalmente desarrolladas para un cluster, usando eficientemente un multi-cluster.
Proponemos una arquitectura del sistema para lograr una máquina virtual multi-cluster transparente a la aplicación que además la dota de escalabilidad y robustez tolerando los problemas de la comunicación por Internet. Esta arquitectura propone un master-worker jerárquico en el que se introducen elementos claves como los gestores de comunicación que dotan al sistema de robustez, seguridad y transparencia en las comunicaciones entre clusters a través de Internet.
Desarrollamos un modelo de prestaciones para poder hacer una estimación teórica del tiempo de ejecución y de la eficiencia de una aplicación ejecutándose en un multi-cluster. La precisión de las estimaciones es superior al 90%.
Proponemos una metodología que da un procedimiento que define los pasos para realizar la predicción del tiempo de ejecución, para garantizar un umbral de eficiencia seleccionando los recursos adecuados y para guiar a la sintonización de la aplicación encontrando los cuellos de botella de la ejecución.
Clusters of computers represent an alternative for speeding up scientific applications. Nevertheless applications grow in complexity and need more resources. The joint of distributed clusters, using Internet, in a multi-cluster can allow the resources obtainment.
A problem on reaching an effective collaboration from multiple clusters is the increase on the computation and communication heterogeneity. This factor increases the complexity of such a system bringing difficulties in its use.
The target of this thesis is to attain the reduction of the execution time of applications, originally written for a single cluster, efficiently using a multi-cluster. In order to reach this goal we propose a system architecture, an analytical model and a performance and tuning methodology.
The proposed system architecture aims to obtain a multi-cluster virtual machine, transparent to the application and that provides scalability and robustness, tolerating possible faults in the Internet communication between clusters. This architecture is organized around a hierarchical master-worker with communication managers. Communication managers are a key element responsible for the robustness, security and transparency in the communication between clusters using Internet.
The analytical performance model was developed to estimate the execution time and efficiency of an application executing in a multi-cluster. The precision on the estimations are over 90%.
The proposed performance prediction and application tuning methodology is a procedure that defines the steps to predict the execution time and efficiency, to guarantee an efficiency threshold and to guide on the application tuning, evaluating the execution bottlenecks.

Повний текст джерелаA problem in modern command and control situations is that much data is available from different sensors. Several sensor data sources also require that the user has knowledge about the specific sensor types to be able to interpret the data.
To alleviate the working situation for a commander, we have designed and constructed a system that will take input from several different sensors and subsequently present the relevant combined information to the user. The users specify what kind of information is of interest at the moment by means of a query language. The main issues when designing this query language have been that (a) the users should not have to have any knowledge about sensors or sensor data analysis, and (b) that the query language should be powerful and flexible, yet easy to use. The solution has been to (a) use sensor data independence and (b) have a visual query language.
A visual query language was developed with a two-step interface. First, the users pose a “rough”, simple query that is evaluated by the underlying knowledge system. The system returns the relevant information that can be found in the sensor data. Then, the users have the possibility to refine the result by setting conditions for this. These conditions are formulated by specifying attributes of objects or relations between objects.
The problem of uncertainty in spatial data; (i.e. location, area) has been considered. The question of how to represent potential uncertainties is dealt with. An investigation has been carried out to find which relations are practically useful when dealing with uncertain spatial data.
The query language has been evaluated by means of a scenario. The scenario was inspired by real events and was developed in cooperation with a military officer to assure that it was fairly realistic. The scenario was simulated using several tools where the query language was one of the more central ones. It proved that the query language can be of use in realistic situations.

Повний текст джерелаIndividuals left to decompose in outdoor environments may be subjected to all manner of carnivore scavenging before they are recovered. This study documents scavenging patterns to determine the effect of multiple species on human-sized pig (Sus scrofa) remains in an outdoor setting. It is hypothesized that that identification of the species involved in scavenging and postmortem damage to bone will correlate with patterns in the way skeletal elements are dispersed from the original point of deposition. Furthermore, the interactions of multiple species of scavengers modifying the same remains will impact the dispersal of skeletal elements differently than in studies documenting single scavenger taxa. The research was conducted on private land in the Yosemite Valley, CA, USA. Six pigs of comparable mass to adult humans were left exposed for five weeks beginning May 22, 2012, and observed daily for the first two weeks. After skeletonization, the bones were mapped, collected, and examined for carnivore modification. Two additional pigs were placed separately and left undisturbed for approximately six weeks, after which a thorough search of the area was undertaken to locate and map skeletal elements. Eighteen defleshed cow (Bos taurus) femora were also secured in the same outdoor environment to document scavenger gnaw marks and behavior. Six additional femora were given to domestic dogs (Canis familiaris) to document gnaw marks and behavior. Results of this study suggest that regular human interaction has an impact on carnivore behavior. During observational period of the study, carnivore activity was nonexistent. Once daily observations had ceased, within two days coyotes (Canis latrans) and wild pigs (Sus scrofa) began scavenging the remains. Coyotes and turkey vultures (Cathartes aura) scavenged the undisturbed pigs as early as two days after deposition, and complete disarticulation had occurred by the end of the six-week study. The cow femora were scavenged by turkey vultures and ravens (Corvus corax) daily regardless of human presence but were only scavenged by coyotes after daily observations had ceased. Analysis of dispersal patterns revealed that a majority of skeletal elements were found either adjacent to the original deposition site or along nearby game trails. This suggests following game trails is an effective technique for law enforcement attempting to locate remains. However, entire carcasses can be removed with minimal skeletal elements or soft tissue left behind, stressing the importance of detailed searches for small bones to establish the original site of deposition.

Повний текст джерелаLangattomat laajakaistaverkot ovat tulleet välttämättömäksi osaksi liikkuvien ihmisten elämää. Lähes kaikki kommunikaatiotarpeet äänipuheluista internettiin pystytään toteuttamaan langattomien verkkojen avulla. Kuitenkin jotta langattomilla verkoilla pystytään tarjoamaan täysi peittävyys yli maan, se vaatii varsin kalliita investointeja verkkoinfrastruktuuriin. Langattomien verkkojen investoinnit koostuvat suurelta osin tukiasemista, jotka tähän asti ovat olleet kullakin verkkotoimittajalla täysin omanlaisensa toteutus. Kun jokainen verkkotoimittaja toteuttaa kaikki tukiaseman osat erilailla, se tarkoittaa että kutakin tukiaseman osia valmistetaan suhteellisesti pienempiä määriä ja sitä myötä niistä tulee mahdollisesti kalliimpia verrattuna standardoituhin modulaarisiin tukiasemaratkaisuihin. Nykyinen tilanne siis osaltaan johtaa siihen että verkkojen rakentaminen ja päivittäminen on kallista. Eräs ratkaisu tähän ongelmaan on tarjolla modulaarisessa tukiasemaratkaisussa ja siksi OBSAI, Open Base Station Initiative, pyrkii modulaarisoimaan ja standardoimaan yhden kalliimmista verkkoinfrastruktuurin osista, tukiaseman. OBSAI standardi pyrkii modularisoimaan tukiasema-arkkitehtuurin ja mahdollistamaan todellisen yhteensopivuuden tukiaseman eri osien välillä. Tätä todellista yhteensopivuutta ei ole vielä täysin pystytty toteuttamaan, johtuen tietyistä standardin epätarkkuuksista. Tässä lopputyössä on analysoitu OBSAI standardia ja identifioitu alueet, joihin pitää keskittyä, kun modulien välistä yhteensopivuutta testataan. Työn lopputulemana myös ehdotetaan useita parannuksia ja muutoksia standardiin, jotta todellinen yhteensopivuus modulien välillä saavutetaan. Painopiste lopputyössä on OBSAI standardin RP3 rajapinta, joka määrittelee kantataajuusosan (BB) ja radiotaajuusosan (RF) välisen rajapinnan. Kun OBSAI standardia saadaan parannettua työssä ehdotetuin toimenpitein, lopputuloksena on oletettavasti alhaisempi tukiaseman kokonaiskustannus, mahdollisuus käyttää yhteensopivia moduleita eri valmistajilta, nopeampi tuotteiden markkinoille vienti sekä parantunut tutkimusyhteistyö eri yritysten välillä.
Trådlösa nät har blivit en nödvändighet i vår allt mer mobila livsstil. Från mobiltelefoni till Internet, trådlösa nät erbjuder många typer av kommunikation. Men att erbjuda trådlös täckning i ett område kan kräva installation av en mängd dyrbar telekomutrustning. En sådan utbyggnad kräver basstationer som fram till nu har varit patentskyddade av respektive leverantör. Och patentskyddad utrustning är oftast både dyrare och mindre flexibel jämfört med standardiserade modulära lösningar. Resultatet är höga kostnader för att uppgradera näten och att utvecklingen försvåras. Ett botemedel är användningen av standardiserade moduler. Därfär försöker Open Base Station Architecture Initiative (OBSAI) att standardisera moduler i ett av de dyraste nätelementen i trådlösa nät, basstationen. OBSAI har som mål att dela upp basstationen i definierade moduler och möjliggöra fullständig interaktion mellan olika moduler. Men på grund av vissa egenskaper hos standarden har detta inte lyckats. Denna studie har undersökt standarden och pekar på områden som man måste fokusera på när man utför tester mellan moduler. Dessutom föreslås flera tillägg till standarden för att möjliggöra bättre interaktion mellan basstationens moduler. Studien fokuserar på RP3- gränssnittet med målet att möjliggöra standardiserad interaktion mellan basbands- och radio-moduler, så att dessa moduler kan kommerisialiseras. Det förväntade resultatet är lägre kostnader, bättre interaktion mellan moduler, snabbare marknadsintroduktion och mer samarbete inom forskning och utveckling.

An integrated development environment (IDE) can reduce the effort of software development in the repeated edit-compile-link-test cycle. An open integrated development environment (OIDE) enables a programmer to access variables and invoke functions directly, and provides a more effective way to test and develop software. However, the user interface of an OIDE may be frozen when some functions are invoked. In order to resolve the freezing problem and to support the development of multi-threaded program, an open environment for multi-threaded programming (MOIDE) is proposed in this paper. An MOIDE manages two kinds of components: static components and dynamic components. We analyze the working of dynamic components and propose the management model of dynamic components. According to the model, a prototype of MOIDE has been implemented.

The purpose of this thesis uses Makeblock materials to design and create a multi-function based environment detection vehicle. The controller of the vehicle is Makeblock Orion. The vehicle is equipped with the fire sensor and the gas sensor. The drive device uses DC motors to implement the motion trajectories. The video device uses the DroidCamApp with the phone lens to transmit image signals to the computer. The multi-function based environment detection vehicle is completed by the Makeblock. The vehicle uses the front-end sensor to detect the gas density. In the disaster area. The sensors measure the high value of the gas density or detect the flame. It will transmit the data and the image to the computer immediately in order to control the vehicle and understand the indoor situation clearly.
