Evolution and development are the two biological processes most associated
with the idea of organic change. Indeed, the very notion of evolution
originally referred to the unfolding of a preformed structure within the developing
embryo and only later acquired its current meaning as the transformation
of species through time. It seems, therefore, only logical to
assume that the biological disciplines that study these two different phenomena-
embryology, later transformed into developmental biology, and
evolutionary biology, especially phylogenetics-would be closely related....
inaccuracies lead to the deviation of operational space trajectory provided by the kinematic
One method to deal with this issue can be found in an adaptive control. Xu and Gu
proposed an adaptive control scheme for space robots in both joint space and operational
space [Xu et al., 1992, Gu & Xu, 1993]. However, the adaptive control proposed in [Xu et al.,
1992] requires perfect attitude control and the adaptive control in [Gu & Xu, 1993] is
developed based on an under-actuated system on the assumption that the acceleration of the
base-satellite is measurable.
A systematic and unified presentation of the fundamentals of adaptive control theory in both continuous time and discrete time
Today, adaptive control theory has grown to be a rigorous and mature discipline. As the advantages of adaptive systems for developing advanced applications grow apparent, adaptive control is becoming more popular in many fields of engineering and science. Using a simple, balanced, and harmonious style, this book provides a convenient introduction to the subject and improves one's understanding of adaptive control theory....
The Air Force Materiel Command (AFMC) develops, acquires, and maintains most Air Force systems and is tailoring its workforce to adapt to changes in technology, weapons, and battlefield requirements. This volume is a practical guide to the main steps in analytical workforce planning and development: determining workforce
This chapter addresses the most general problem formulation of detection in
linear systems. Basically, all problem formulations that have been discussed
so far are included in the framework considered. The main purpose is to
survey multiple model algorithms, and a secondary purpose is to overview
and compare the state of the art in different application areas for reducing
complexity, where similar algorithms have been developed independently.
In Chapter 2 the equalizers operated under the assumption of perfect channel estimation, where the receiver always had perfect knowledge of the CIR. However, the CIR is typically time variant and consequently the receiver has to estimate the CIR or the coefficients of the equalizer, in order to compensate the IS1 induced by the channel. for Algorithms have been developed in order to automatically adapt the coefficients of the equalizer directly [ l 181 or by utilizing the estimated CIR [124,125]....
This paper presents an analysis of the benefits of climate change adaptation from small and medium scale hydropower plants in Lao Cai Province. Lao Cai is a mountainous province with high hydropower potential. Totally 116 small and medium hydropower projects in different stages of development have been identified with installed capacities ranging from 0.9 MW to 60 MW. Based on the results of statistic downscaling, four climate change scenarios were developed for the Lao Cai province area.

The universities must develop new fields of multi-discipline research in
building design, engineering, energy and carbon efficiency, directed towards
providing the industry with feedback on the success or otherwise of current
initiatives. This will create numerous opportunities for industrial and
international partnerships, supported by a wide range of new funding and
revenue streams, not traditionally available to academic researchers.
In so few words, this poem beautifully captures what is so vital about early
emotional development and its importance in the human condition. It is the
willingness and ability to embrace fully and experience the broad spectrum of
emotional states, including those that are painful and distressing, that may be
key to mental health and adaptive personal development.
In spite of decades of research on word sense disambiguation (WSD), all-words general purpose WSD has remained a distant goal. Many supervised WSD systems have been built, but the effort of creating the training corpus - annotated sense marked corpora - has always been a matter of concern. Therefore, attempts have been made to develop unsupervised and knowledge based techniques for WSD which do not need sense marked corpora. However such approaches have not proved effective, since they typically do not better Wordnet ﬁrst sense baseline accuracy. ...
We describe a distributed, modular architecture for platform independent natural language systems. It features automatic interface generation and self-organization. Adaptive (and nonadaptive) voting mechanisms are used for integrating discrete modules. The architecture is suitable for rapid prototyping and product delivery.
We describe the adaptation to French of a machine-learned sentence realization system called Amalgam that was originally developed to be as language independent as possible and was first implemented for German. We discuss the development of the French implementation with particular attention to the degree to which the original system could be reused, and we present the results of a human evaluation of the quality of sentence realization using the new French system.
In this demo we will present GATE, an architecture and framework for language engineering, and ANNIE, an information extraction system developed within it. We will demonstrate how ANNIE has been adapted to perform NE recognition in different languages, including Indic and Slavonic languages as well as Western European ones, and how the resources can be reused for new applications and languages.
The lack of positive results on supervised domain adaptation for WSD have cast some doubts on the utility of handtagging general corpora and thus developing generic supervised WSD systems. In this paper we show for the ﬁrst time that our WSD system trained on a general source corpus (B NC) and the target corpus, obtains up to 22% error reduction when compared to a system trained on the target corpus alone. In addition, we show that as little as 40% of the target corpus (when supplemented with the source corpus) is sufﬁcient to obtain the same results as training...
We investigate the problem of domain adaptation for parallel data in Statistical Machine Translation (SMT). While techniques for domain adaptation of monolingual data can be borrowed for parallel data, we explore conceptual differences between translation model and language model domain adaptation and their effect on performance, such as the fact that translation models typically consist of several features that have different characteristics and can be optimized separately.
This article raises questions that must be solved if psychol- ogists are to develop a science of positive psychology. First, how should psychology quantify positive mental health? At present, psychology has no metric except per-haps scores of greater than 85 on the DSM-1V's Axis V (Global Assessment of Functioning). If more reliable meth- ods or assessing the relative maturity of defenses can be developed, psychology may gain a means of quantifying the theoretical formula for positive mental health that Marie Jahoda (1959) offered to psychology 40 years ago.
This publication sheds light on the issue of decentralisation in Mexico. It shows that decentralisation can make decision-making more efficient and increase local participation in development issues. Decentralisation can provide a better framework to improve local infrastructure and to channel the necessary finance from public and private sources. The modernisation of infrastructure systems in Mexico's cities and regions would improve the quality of life and stimulate economic development, thus fostering entrepreneurship and employment.
Thesis systematized research institutions, state administrative institutions, institutional capacity building, thereby, to clarify the concept of state administrative institutions, capacity of State administrative institutions. The thesis also defines the role of the state institutions and administrative requirements on institutional capacities to adapt to the market economy and international integration. The thesis studies and assess the status of the administrative capacity of state institutions Vietnam in the market economy and international integration.
