Forty-five years ago, agricultural and pharmaceutical chemistry appeared to be following
divergent paths. On the agricultural scene industrial companies were concentrating on the
synthesis of various classes of compounds and when a successful chemical candidate was
discovered, there was a good deal of joy among the synthetic chemists. We were told that
as a result of chemistry life would be better and, indeed, it was. Armed with synthetic agrochemicals,
the American farmer became the envy of the world....
In the autumn of 1994, a New Yorker cartoonist imagined a clinical scene
in which a patient who is literally radiant with health, his body throwing
off a nearly blinding aura of wellness, is nevertheless being sternly admonished
by his physician because he has achieved his health the wrong way:
“You’ve been fooling around with alternative medicines, haven’t you?” the
New Yorker cartoons constitute the most sensitive of barometers to shifting
currents in America’s cultural atmosphere.
The language of scene descriptions 2 must allow a hearer to build structures of schemas similar (to some level of detail) to those the speaker has built via perceptual processes. The understanding process in general requires a hearer to create and run "event ~ " to check the consistency and plausibility of a "picture" constructed from a speaker's description.
In this paper the experience made through the development of a NAtural Language driven Image Generation is discussed. This system is able to imagine a static scene described by means of a sequence of simple phrases. In particular, a theory for equilibrium and support will be outlined together with the problem of object positioning.
CarSim is an automatic text-to-scene conversion system. It analyzes written descriptions of car accidents and synthesizes 3D scenes of them. The conversion process consists of two stages. An information extraction module creates a tabular description of the accident and a visual simulator generates and animates the scene. We implemented a first version of CarSim that considered a corpus of texts in French. We redesigned its linguistic modules and its interface and we applied it to texts in English from the National Transportation Safety Board in the United States. ...
Carsim is a program that automatically converts narratives into 3D scenes. Carsim considers authentic texts describing road accidents, generally collected from web sites of Swedish newspapers or transcribed from hand-written accounts by victims of accidents. One of the program’s key features is that it animates the generated scene to visualize events. To create a consistent animation, Carsim extracts the participants mentioned in a text and identiﬁes what they do.
In this paper a system which understands and conceptualizes scenes descriptions in natural language is presented. Specifically, the following components of the system are described: the syntactic analyzer, based on a Procedural Systemic Grammar, the semantic analyzer relying on the Conceptual Dependency Theory, and the dictionary.
The epidemiology of infectious diseases is one of the great triumphs of applied
ecology. In particular, the public health importance of parasites has
lead to a large literature, exploring their impact on the population dynamics,
population genetics and evolutionary biology of human populations. An
important milestone was the Dahlem Conference on population biology of infectious
diseases, held in 1981. The resulting book (Anderson and May 1982)
lucidly summarised the contemporary state of parasite ecology and epidemiology.
The field of digital image segmentation is continually evolving. Most recently, the advanced segmentation methods such as Template Matching, Spatial and Temporal ARMA Processes, Mean Shift Iterative Algorithm, Constrained Compound Markov Random Field (CCMRF) model and Statistical Pattern Recognition (SPR) methods form the core of a modernization effort that resulted in the current text. This new edition of "Advanced Image Segmentation" is but a reflection of the significant progress that has been made in the field of image segmentation in just the past few years.
The interplay between geometry and topology on complex algebraic varieties is a classical theme that goes back to Lefschetz [L] and Zariski [Z] and is always present on the scene; see for instance the work by Libgober [Li]. In this paper we study complements of hypersurfaces, with special attention to the case of hyperplane arrangements as discussed in Orlik-Terao’s book [OT1]. Theorem 1 expresses the degree of the gradient map associated to any homogeneous polynomial h as the number of n-cells that have to be added to a generic hyperplane section D(h) ∩ H to obtain the complement in...
The wavelet transform is a new arrival on the mathematical scene. It is widely applied in the area of engineering, image processing. In this paper, we present the main concepts of wavelet, the averaging and differencing technique related to a wavelet decomposition, a linear algebra implementation of the Haar wavelet transform.
Standing alone in a viewing chapel in a London funeral parlour almost a decade ago I
was struck by the impossibility of coming to terms with the fact that one day I too
would be lying in a spot-lit niche like the one before me. How could I become an inert
object, not experiencing the scene, not there to tell the story? I have been studying
death ever since. To be honest I cannot say that my efforts to come to terms with this
aspect of life have been totally successful. Our mortality is a troubling matter. Yet my
interest in the topic of death has...
This paper describes an operational system which can acquire the core meanings of words without any prior knowledge of either the category or meaning of any words it encounters. The system is given as input, a description of sequences of scenes along with sentences which describe the [EVENTS] taking place as those scenes unfold, and produces as output, a lexicon consisting of the category and meaning of each word in the input, that allows the sentences to describe the [EVENTS]. It is argued, that each of the three main components of the system, the parser, the linker and the...
The paper presents a new model for contextdependent interpretation of linguistic expressions about spatial proximity between objects in a natural scene. The paper discusses novel psycholinguistic experimental data that tests and veriﬁes the model. The model has been implemented, and enables a conversational robot to identify objects in a scene through topological spatial relations (e.g. “X near Y”). The model can help motivate the choice between topological and projective prepositions.
We present a text-based approach for the
automatic indexing and retrieval of digital photographs taken at crime scenes. Our research prototype, SOCIS, goes beyond keyword-based approaches and methods that extract syntactic relations from captions; it relies on advanced Natural Language Processing techniques in order to extract relational facts. These relational facts consist of a "pragmatic relation" and the entities this relation connects (triples of the form: ARG1REL- ARG2).
Light is essential to sight. Without light there is no sight, at least not with our natural eyes. Because figure drawing begins with seeing, a book about figure drawing should have some significant information on the nature of light and how our eyes perceive it. Understanding how light works on objects in a scene helps the artist create a feeling of depth and substance in a drawing. In Figure 7.1 the lighting on the dress indicates that it is a dark satin material. In nature the artist often doesn’t have much control over the lighting of a scene. About...
The use of plastics has increased almost 20-fold in the last 30 years. Plastics have come on the scene
as the result of a continual search for man-made substances that can perform better or can be produced at a lower cost than natural materials such as wood, glass, and metal, which require mining, refining, processing, milling, and machining.

The availability of such rich imagery of large parts of
the earth’s surface under many different viewing conditions
presents enormous opportunities, both in computer vision
research and for practical applications. From the standpoint
of shape modeling research, Internet imagery presents the
ultimate data set, which should enable modeling a significant
portion of the world’s surface geometry at high resolution.
With the fullest sense of the responsibility incurred by the addition of another volume to the countless
numbers already existing, and daily appearing in the world, the following Diary has been committed to the
press, trusting that, as it was not written WITH INTENT to publication, the unpremeditated nature of the
offence may be its extenuation, and that as a faithful picture of travel in regions where excursion trains are
still unknown, and Travellers' Guides unpublished, the book may not be found altogether devoid of interest or
