One of the main advantages of this technique is that it can produce the scaffold with main
structural feature suitable for growth of the cell and subsequent tissue organization (Li &
Tuan, 2009; Liang et al., 2007; Leong et al., 2008). It can produce the ultra fine fibers with
special orientation, high aspect ratio, high surface area, and having control over pore
In text categorization, feature selection (FS) is a strategy that aims at making text classifiers more efficient and accurate. However, when dealing with a new task, it is still difficult to quickly select a suitable one from various FS methods provided by many previous studies. In this paper, we propose a theoretic framework of FS methods based on two basic measurements: frequency measurement and ratio measurement. Then six popular FS methods are in detail discussed under this framework.
Renewable natural resources
in the forefront to save the environment and we must do our best to find
applications suitable for them.
The production process is shown by the method of casting, rolling process
including monitoring throughout the process. Innovative testing procedures described in
electrochemistry, ultrasonic pulse velocity, fracture toughness in the macro-micro
mechanical behavior and more. The coordination between the components, laminas and
building parts are checked by different principles....
As with micromachining processes, many MEMS sensor-packaging techniques are
the same as, or derived from, those used in the semiconductor industry. However,
the mechanical requirements for a sensor package are typically much more stringent
than for purely microelectronic devices. Microelectronic packages are often generic
with plastic, ceramic, or metal packages being suitable for the vast majority of IC
The MICROMASTER 410 inverter is suitable for a variety of variable-speed drive applications. It is especially suitable for use with pumps and fans, as a drive in various sectors, e.g. food, textile and packaging industries as well as for conveyor systems, factory gate and garage door drives and as a universal drive for moving billboards.
Yet – outside the major pension funds and insurance companies – institutional investor allocations to clean
energy projects remain limited, particularly when it comes to the types of direct investment which can help
close the financing gap. Reasons for institutional investor hesitancy include a lack of information and
expertise when it comes to the type of direct infrastructure investment required to finance clean energy
projects, and a potentially unsupportive regulatory backdrop.
Commodity-level analysis illustrates the size of opportunities and the
importance of technology. In many African countries with large amounts of
suitable but currently uncultivated land, transfers of technology could pro-
vide large benefits to local populations. To reduce risks and increase benefits,
greater effort will be needed to identify local comparative advantage, assess
the technical viability of proposed investments, improve weak institutional
frameworks for land governance, and level the playing field for smallholder
Basic Korean: A Grammar and Workbook comprises an accessible reference grammar and related exercises in a single volume. This workbook presents twenty-five individual grammar points in lively and realistic contexts, covering the core material which students would expect to encounter in their first year of learning Korean. Grammar points are followed by examples and exercises which allow students to reinforce and consolidate their learning. Basic Korean is suitable for both class use as well as independent study.
Colloquial English is an easy-to-use course, specially written by an experienced teacher for self-study or class use. It teaches current spoken and written English, as used in the UK, through the medium of English itself. This course assumes a basic knowledge of English and is suitable for post-beginners, whether studying on their own or as part of a class.
full explanations and illustrations of grammatical terms
pronunciation guide to help with areas of particular difficulty

Ebook 2016 colection IELTS all speaking topics and sample answers speacial features: full topics that appread in the actual speaking section; simple answer, suitable for learners of all levels; searchable contents, easy to find desired topics.
This textbook will be designed for fixed-income securities courses taught on MSc Finance and MBA courses. There is currently no suitable text that offers a 'Hull-type' book for the fixed income student market. This book aims to fill this need. The book will contain numerous worked examples, excel spreadsheets, with a building block approach throughout. A key feature of the book will be coverage of both traditional and alternative investment strategies in the fixed-income market, for example, the book will cover the modern strategies used by fixed-income hedge funds.
This practical book gives a comprehensive introduction to the concepts and languages of the new standard IEC 61131 used to program industrial control systems. A summary of the special requirements in programming industrial automation systems and the corresponding features in the IEC 61131-3 standard makes it suitable for students as well as PLC experts. The material is presented in an easy-to-understand form using numerous examples, illustrations and summary tables. There is also a purchaser's guide and a CD-ROM containing two reduced but functional versions of programming systems.
It will be found equally suitable for quick reference to details and for the more leisured study of broad grammar topics. A useful feature of the book is the inclusion of example texts and conversations, many of them authentic, to show how grammar is used in connected writing and in speech.
KRONE cables are low skew products, i.e. the difference in propagation delay between
the individual pairs is very low. This is increasingly being requested for Gigabit
Ethernet. The suitability of the cable for high-bit-rate transmission systems ensures a
high degree of future proofing. Additional features are the slim design and low weight
of the cables. Each pair is individually shielded with foil (STP) and around the stranded
pairs (PIMF) we designed this kind with a extra foil.
In order to be suitable for tribological applications, polymeric materials, which can usually
exhibit mechanical strength, lightness, ease of processing, versatility and low cost, together
with acceptable thermal and environmental resistances, have to show good abrasion and
wear resistance. This target is not easy to achieve, since the viscoelasticity of polymeric
materials makes the analysis of the tribological features and the processes involved in such
phenomena quite complicated.
MPEG-7 will deﬁne a certain set of descriptors to describe these features. For example, the color histogram can be a very suitable descriptor for color characteristics of an image, and motion vectors (commonly available in compressed video bitstreams) form a useful descriptor for motion characteristics of a video clip. MPEG-7 also uses the concept of description scheme (DS), which means a framework that deﬁnes the descriptors and their relationships. Hence, the descriptors are the basis of a description scheme. Description then implies an instantiation of a description scheme.

It has been my object in these pages to present the life of each
astronomer in such detail as to enable the reader to realise in
some degree the man's character and surroundings; and I have
endeavoured to indicate as clearly as circumstances would permit
the main features of the discoveries by which he has become known.
FlexWave MMW 100 is a point-to-point millimeter wave transmission system that operates in
the licensed 71GHz to 86GHz spectrum and provides fiber-speed wireless Line of Sight (LOS)
communications links within a 1 – 6 km range. The MMW 100 features a 10” lens instead of a 2’
antenna making the product suitable to mount on electric poles and any other medium without
the restrictions of high pointing stability. The MMW 100 has the largest beam width allowed by
the FCC in the 71-86 GHz band (1.2 deg.)....
