PDF Ebook Mixed Speculative Multithreaded Execution Models

Submitted by antoq on Fri, 04/29/2011 - 08:58

The current trend toward chip multiprocessor architectures has placed great pressure on programmers and compilers to generate thread-parallel programs. Improved execution performance can no longer be obtained via traditional single-thread instruction level parallelism (ILP), but, instead, via multithreaded execution. One notable technique that facilitates the extraction of parallel threads from sequential applications is thread-level speculation (TLS). This technique allows programmers/compilers to generate threads without checking for inter-thread data and control dependences, which are then transparently enforced by the hardware. Most prior work on TLS has concentrated on thread selection and mechanisms to efficiently support the main TLS operations, such as squashes, data versioning, and commits.

PDF Ebook Structure in Architecture

Submitted by antoq on Fri, 05/14/2010 - 08:17

This curriculum unit is designed to give students an integrated interpretation of structures, structural elements, and their functions. This unit will help students make critical connections between standard science objectives taught in the classroom and the applications of those objectives in the real world of building structures.

Students will engage in activities that will foster understanding of how principals of both math and science are incorporated in the design and construction of buildings. The unit is designed to give students an opportunity to explore basic principals and concepts associated with architecture through hands-on activities.

PDF Ebook Historic Buildings and Contemporary Additions

Submitted by antoq on Fri, 05/14/2010 - 07:52

The intention of this project is to take a closer look at the use of contemporary styles for new additions to historic buildings. The use of a new and different style for additions on historic buildings, also known as contrasting styles, is one of the most typical approaches in the field, yet observing the variation in the results obtained when architects use contrasting additions in historic buildings, causes one to question this approach. What is it that makes projects like this succeed or fail? This research, will explore the key elements that allow historic buildings and contemporary additions to work cohesively, respecting and promoting each other’s architectural significance. Using the results, I will consider the feasibility of establishing design guidelines to promote the use of specific design elements for the expansion of historic buildings.

New architectural styles can actually reinforce the significance and architectural value of historic buildings. By labeling architecture as an old or new style, we are recognizing a timeframe for the use of unique and symbolic details that have value and meaning for a specific group. These symbolic details are the language that helps to illustrate or convey the evolution of our society. The styles expressed on historic buildings represent the language of the past and the new styles will represent our present in the future. For this reason, it is important to create an environment where both can coexist and correlate with each other, building additions to historic buildings using contemporary architecture styles with an honest representation of current social situations, while protecting the historic structure which represents the social situations of our past.

PDF Ebook Chaos and Geometric Order in Architecture and Design

Submitted by antoq on Wed, 03/03/2010 - 03:02

It is relatively easy to distinguish between geometric order and chaos in architectural compositions, but the definition of these concepts is difficult. The following definitions can be assumed: The geometric order is represented by ideal mathematical forms (in 2D: e.g. line, circle, quarter, or 3D: e.g. plane, sphere, cube) and ideal relationships (e.g. perpendicularly, parallelism, symmetry, rhythm/regularity). Chaos is the opposite of geometric order; it is represented by forms and relationships that are complex and difficult to describe with the language of classic mathematics.

From the point of view of spatial perception, other definitions can be assumed. In Fig. 1 two graphic compositions are presented, which consists of about 1600 points each. The average density of points is constant in the whole area of both compositions. In the first composition the circular area of regular points is visible on the background of random points. The other composition is inverse: the circular area of random points is visible on the background of regular points. Based on this example, we can indirectly define chaos as an interference of geometric order and geometric order – as an interference of chaos.

PDF Ebook A Study of Landscape Architecture Design Methods

Submitted by antoq on Sat, 02/13/2010 - 02:34

How do different methods employed by landscape architects impact the design outcome? This paper identifies and defines design methods in landscape architecture that may be classified as part of four internal and external connections and structures categories. Methods are further examined through two design exercises. In the first design exercise, the identified methods are individually applied to the same simple design which is used as a control. The only variable changed is the method used to design. The resulting designs are shown and analyzed. In the second design exercise, three different methods are applied to a complex design. Similar to the first design exercise, all variables are held constant except for the design methods. The resulting design outcomes are shown and analyzed. One conclusion from this work recommends landscape architecture designers use at least one method in each of four categories: 1) Modeling Systems, 2) Interrelationship and Dependencies, 3) Incorporation and Adadaption, and 4) Structure Problems in order to explore complex design issues more thoroughly.

This thesis centers on the key question: What effect do different design methods employed by landscape architects have on the design outcome?
One component of the design process in landscape architecture is methodology, which should be a conscious choice of methods to achieve a desired result. However, many times the choice of methodology is not given much thought. The designer chooses a methodology that she or he is comfortable with or has used in the past with no little or no thought on how this choice meshes with the objective of the design. (Lynch, 270)

PDF Ebook Sentiment in Traditional Thai Architecture

Submitted by antoq on Sat, 02/13/2010 - 02:15

Traditional Thai Architecture was initially created from Thai behavior on the basis of beliefs. Each feature, for instance, had different decorated styles; nevertheless, they had the same main function such as Spaces created by separated time zoning, split step floors, being made of natural material and prefabricated building elements. This article aims to analyze the spiritual aspect of Traditional Thai Architecture by the Systems Method. The results imply that knowledge of Thai ancestry was forged from the former environment; furthermore, the appearance appealed to all six common human contact points of eye, ear, nose, tongue, body and mind. Consequently, the buildings and the surroundings were plentiful in their display of visible-objects, sounds, aromas, tastes, touch and mind-objects. The entire system of appearance generated the Sentiment of Traditional Thai Architecture. This should be a clue to the fact that the transition between human needs and Thai culture is Traditional Thai Architecture. The results show that eye contact, ear contact, and body contact influence perception to enhance the value of Traditional Thai Architecture. Therefore, today’s Thai Architecture should be adapted to these criteria, which should be considered by designer, for conserving Traditional Thai Architecture.

The origin of the Thai race is still ambiguous. Some assume they migrated from Southwestern China, others believe they lived in the border areas between China, Laos, Burma, and Thailand for at least 2,000 years, and still others suggest that they became established in what is today Thailand and then transferred northwards.

Ebook Service Oriented Architectural Design

Submitted by wulan on Thu, 01/21/2010 - 08:39

Service orientation is becoming a standard paradigm in the development of software applications. The paradigm is centred around the notion of service, i.e. a computational entity whose functional and non-functional aspects can be described in a standard document to be advertised in some service registries and made available for discovery. Contrary to traditional applications, service oriented ones are not just statically assembled. Instead, they have the potentialities for allowing dynamic assembly via publication, discovery, selection and binding.

SEnSOria (Software Engineering for Service-Oriented Overlay Computers) is a research project that aims to develop a novel and comprehensive approach for engineering service oriented computations. Key issues of SEnSOria concern the early stage and development of service specification, like design and reconfiguration of service-based architectures. In this setting, the configuration of a system consists of the present components and interconnections (i.e. the architecture), together with their current state. Architectural styles can be applied to reuse existing design patterns and thus facilitate software development.

Ebook Deference to Committees in the Antebellum House

Submitted by wulan on Tue, 08/18/2009 - 05:07

One of the most commonly-observed characteristics of the modern House of Representatives is that the floor of the House exhibits a high degree of deference to standing committees’ bill proposals. Indeed, though there is substantial disagreement about the reasons and implications of this deference, theoretical and empirical scholars of various stripes agree that bills reported from committees enjoy high levels of success during floor consideration. In stark contrast, however, various historical and political science studies of committees in the earliest decades of congressional history paint a picture of committees as subservient agents of the House as a whole, with little independent influence upon House decision making.

Perhaps surprisingly, given this sharp difference in the perceived role of committees in the legislative process, and given also the centrality of committees in studies of Congress, little work systematically addresses questions about either the timing or causes of the emergence of deference to committee decisions. Some scholars suggest that deference emerged along with the standing committee system itself in the period from roughly 1815-1825, while others suggest that deference still was not the norm as late as the end of the 19 th century.

PDF Ebook Construction Manual For Earthquake-Resistant Houses Built of Earth

Submitted by antoq on Wed, 08/12/2009 - 07:21

The solutions proposed in this manual concentrate on low-cost single-story houses, built from earth in rural areas of earthquake-prone zones. They are based on research projects carried out at the Forschungslabor für Experimentelles Bauen (Building Research Laboratory) of the University of Kassel, Germany, on the analysis of earthquake damage in Latin America, on studying relevant literature and on the implementation of several test structures in Germany and prototype houses in Guatemala, Ecuador and Chile.

Using locally available building materials as well as the skills of local craftsmen should be considered for the design of seismic-resistant (earthquake proof) houses and it should be proved that the solutions are accepted by the users.

Ebook House-KEEPER, A Vendor-Independent Architecture For Easy Management Of Smart Homes

Submitted by wulan on Fri, 08/07/2009 - 05:02

Currently, two main technologies compete to be the standard in home network middleware. The obvious reason is that the market is extremely significant, speaking of systems which will have the ubiquity of televisions, the upgradability of PCs (Personal Computers) and the broad possibilities of software applications. Cahners In-Stat Group [CISG00] expects more than a $2 billion Internet residential gateway market segment by 2003.

Hence, Microsoft [MS] promotes UPnP [UPNP], a technology closely related to its set of products, and Sun Microsystems [SUN] continues to develop its Jini [JINI] technology, a Java-based [JAVA] solution for intelligent network infrastructure. In the following chapters, we will describe how these technologies provide all functionalities for federating those new Web-enabled, network-enabled daily appliances, called smart devices.
