در این رساله به مطالعه ی رفتار گروه های هموتوپی شبه توپولوژیکی فضاهای حدمعکوس می پردازیم. به طور دقیق تر شرایطی را ارائه خواهیم داد که تحت این شرایط گروه های هموتوپی فضاهای حد معکوس و به طور خاص تر فضاهای حاصلضرب، گروه توپولوژیکی شوند. همچنین شرایطی را برای شمارایی گروه های هموتوپی ارائه خواهیم داد. یک توپولوژی روی گروه های هموتوپی شکل قرار خواهیم داد که آن را با ? ?_k^top (x,x) نشان می ده...
Ability to offer a citizen-centric view of government model is the key to a successful e-government service. Life-event model is the most widely adopted paradigm supporting the idea of composing a single complex egovernment service that corresponds to an event in a citizen’s life. Elementary building blocks of Life-event are based on atomic services offered from multiple government agencies. Th...
One of the main obstacles hindering the use of large-scale agent-based simulation in practice is its scalability. The ability to run realistic and complex agent-based models is desirable to provide empirically and practically useful results. One of the suggested solutions is to run the agentbased models on top of a scalable parallel discrete-event simulation engine. This proposal raises a quest...
Wireless sensor networks consist of tiny devices that usually have severe resource constraints in terms of energy, processing power and memory. In order to work efficiently within the constrained memory, many operating systems for such devices are based on an event-driven model rather than on multi-threading. While event-driven systems allow for reduced memory usage, they require programs to be...
We propose a two-step Event-Level Feature (ELF) learning framework for automatic detection of semantic events. In the first step an elementary-level feature is generated to represent images and videos. Then in the second step an ELF is constructed on top of the elementary features to model each event as a feature vector. Semantic event detectors can be built based on the ELF. Various ELFs are g...
Environmental monitoring is a critical process in areas potentially affected by natural disasters. Nowadays, the distributed processing of vast amounts of heterogeneous sensor data in real time is a challenging task. Event processing tools allow creating an event abstraction layer on top of sensor data. Users can define event patterns to filter in real-time the information they are interested i...
Salient visual singleton stimuli produce spatial cueing effects indicative of attentional capture only when they match current task sets, suggesting that capture is subject to top-down control. However, such task-set contingent capture effects could be associated with the top-down controlled disengagement of attention from non-matching stimuli that follows their initial bottom-up salience-drive...
Top-down modulation underlies our ability to selectively attend to relevant stimuli and to ignore irrelevant stimuli. Theories addressing neural mechanisms of top-down modulation are driven by studies that reveal increased magnitude of neural activity in response to directed attention, but are limited by a lack of data reporting modulation of neural processing speed, as well as comparisons with...
Searches are presented for direct production of top or bottom squark pairs in proton–proton collisions at the CERN LHC. Two searches, based on complementary techniques, are performed in all-jet final states that are characterized by a significant imbalance in transverse momentum. An additional search requires the presence of a charged lepton isolated from other activity in the event. The data w...
A new set of measurements of the top quark mass are presented, based on the proton-proton data recorded by the CMS experiment at the LHC at ffiffi s p 1⁄4 8 TeV corresponding to a luminosity of 19.7 fb−1. The top quark mass is measured using the leptonþ jets, all-jets and dilepton decay channels, giving values of 172.35 0.16ðstatÞ 0.48ðsystÞ GeV, 172.32 0.25ðstatÞ 0.59ðsystÞ GeV, and 172.82 0.1...
