Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Measurement of solar radiance demands expensive devices to be used. Alternatively, estimator models are used instead. In this paper, a new method based on the empirical equations is introduced to estimate the monthly average daily global solar radiation on a horizontal surface. The proposed method uses Intelligent Water ...

We investigate line drawings as an alternative method to train an object detector. While traditional approaches rely on learning an object class from example images, we make use of abstraction provided by the artist. Our object class of choice are cats, posing a challenging detection problem by a variety of poses and appearances. In order to deal with this flexibility, and similar to part-based...

The problem of modeling large-scale virtual urban environments has remained challenging for computer graphics researchers and urban planners. Cities are difficult to model in detail, since they hold diverse and complex geometries. Building large-scale 3D city models by means of photogrammetric reconstruction is a time and resource intensive, often semi-automatic process and does not provide dat...

Economic markets are complex systems. They are characterized by a large and dynamic population of firms. To deal with this complexity, we propose an adaptive multi-agent system which models a set of firms in competition with each other within a shared market. The firms are represented by agents; each firm is represented by an adaptive agent. We show the advantages of adaptive agents to represen...

We consider the problem of parsing human poses and recognizing their actions in static images with part-based models. Most previous work in part-based models only considers rigid parts (e.g., torso, head, half limbs) guided by human anatomy. We argue that this representation of parts is not necessarily appropriate. In this paper, we introduce hierarchical poselets—a new representation for model...

Artiicial life has long held out the promise of revolutionizing how scientists approach a variety of problems. In this paper we describe an application of ar-tiicial life techniques to the study of a fundamental problem in economics: How does a rm transition from monopoly behavior to competitive behavior as other rms enter the market? Solving traditional economic models provides the equilibrium...

Previous researchers in knowledge-based systems verification have concentrated on developing various approaches and computational tools to find errors in knowledge bases . However , unlike software engineering for traditional systems , there has been little investigation of the relationship between errors and system size . In addition , there has been little analysis of the relationship between...

Security subsystems are often designed with flawed assumptions arising from system designers’ faulty mental models. Designers tend to assume that users behave according to some textbook ideal, and to consider each potential exposure/interface in isolation. However, fieldwork continually shows that even well-intentioned users often depart from this ideal and circumvent controls in order to perfo...

Two key stylised facts have been established about the extinction patterns of firms. First, the probability of extinction is highest at the start of the firm’s existence, but soon becomes more or less invariant to the age of the firm. Second, a very recent finding, that the relationship between the size and frequency of firm extinctions is closely approximated by a power law. Economic theory ha...
