Biquadratic Filter Applications Using a Fully-Differential Active-Only Integrator

A new class of active filters, real active-only filters is described and possible implementation issues of these filters are discussed. To remedy these issues, a fully-differential active-only integrator block built around current controlled current conveyors is presented. The integration frequency of the proposed circuit is adjustable over a wide frequency range. As an application, a real active-only filter based on the classical two-integrator loop topology is presented and designed. The feasibility of this filter in a 0.35µm CMOS process is verified through SPECTRE simulation program in the CADENCE design tool

Structural asessment and strengthening of Atatürk's mausoleum, Anitkabir

Anıtkabir is the mausoleum of Mustafa Kemal Atatürk, the commander of Turkish War of Independence and the founder of Republic of Turkey. Rather than a work of architecture, Anıtkabir has been a symbol and a focal center of Atatürk’s principles, republican revolutions and modern Turkey

Promoting Sustainable Development Through Participatory Design in a Small Town:: Mebane, North Carolina: 2nd Phase

The goal of this project is to generate appropriate design guidelines and implementation strategies for development in key locations of downtown Mebane, North Carolina. One of the main objectives of the project is to enhance community participation in this process. The appropriate goal setting technique in this regard is chosen as charrette process, i.e., the rapid pace at which the design is finalized with a guiding principle: consensus (Sanoff, 2000). The charrette process is planned in three phases. In the first phase, objectives and strategies were determined based on the identified problems. The second phase elaborates on design implications of these strategies. Finally, in the third phase the appropriate design guidelines will be generated for the development of downtown Mebane. Following the first phase of the process, which was presented in the ARCC spring 2001 conference, second phase is prepared, illuminating the third phase

MAKING A SMALL TOWN LIVABLE:: PROMOTING SUSTAINABILITY THROUGH A NEW URBANIST APPROACH IN MEBANE, NORTH CAROLINA

A contemporary nexus of urban development discussions is the concept of sustainability, which is often presented as a viable remedy to many of the contemporary urban ills, i.e., diminished livability that is mostly blamed on suburban sprawl. Not only large metropolitan areas experience sprawl. Numerous relatively small towns have also been undergoing this kind of spatial transformation as their cores are emptied in favor of suburbs. Town of Mebane, North Carolina, is one such small town. Today, downtown Mebane is home to manufacturing plants, retail stores, institutional buildings, and residences as well as empty lots and boarded-up buildings. Its architectural scale is still charming and its gridiron network of streets is capable of accommodating various modes of traffic although precedence is given to the car. Furthermore, some of the downtown buildings are worthy of consideration as historic landmarks, although many have been clad with metal panels, disguising their authenticity. This paper is a progress report on the first of three phases of an urban design actionresearch project on downtown Mebane, being undertaken by NC State University Architecture Faculty and Doctoral Students. The goal of the project is to generate sustainable urban development principles, guidelines and standards that promote urban livability. This phase involves an inventory of the town's physical, social, environmental and economical resources with New Urbanist "lenses" to develop specific sustainable urban development goals for the town's future and strategies to achieve these. In the subsequent phase of the project, proposals will be developed with citizens' input through citizens' charettes. It is envisioned that the process and the consequent proposal developed for Mebane is presented as a model to other small North Carolina towns that are striving to alleviate many of the ills of sprawl in the last phase of the project

Research Based Decision Making in Architectural Programming of Workplaces:: Case of Pamlico County Government Offices, North Carolina

Social, economical and technological developments in the recent decades, especially in the early days of the twenty-first century have consistently revealed the importance of knowledge as a base for decision-making processes. The ever-increasing dependence of productivity and competitiveness on knowledge in many fields has resulted in perception of knowledge as a commodity itself (Castells and Hall 1994). Consequently, the emphasis on knowledge generation has been identified by extensive research based applications in many fields and many societies. Within the field of architecture, knowledge generation and knowledge-based practices have started to be complementary to decision making and design processes especially in the last decades. The connotation of architecture with "art and design” has been accompanied by increased knowledge generation efforts, which has also brought architecture a connotation with "science”. The resultant forces have complemented the term "architecture as art” with another: "architecture as a knowledge-based tool” (Toker and Rifki 2001)

Nebivolol might be Beneficial in Osteoporosis Treatment: A Hypothesis

Nebivolol is a β-blocker that is highly selective for β1-adrenergic receptors with vasodilating properties. This property can be attributed to an endothelial release of nitric oxide (NO). It has been reported that nebivolol also reduces intracellular oxidative stress. There are some studies conducted in humans and animal models which have shown that NO is an important regulator of bone metabolism. However, oxidative stress and antioxidant systems may play important roles in the pathogenesis of osteoporosis. In this paper, we hypothesized that nebivolol may have beneficial effects via nitric oxide and antioxidant action in osteoporosis treatment

Short-Term Outcome of Combined Corticosteriod and Local Anaestetic Therapy with Home-Based Exercıse Programme in Painful Shoulder Conditions

Purpose: The aim of this study was to evaluate the efficacy of combined local corticosteroid and anaestethic therapy with home exercise programme in the treatment of painful shoulder conditions. Methods: 40 mg Depomedrol® (methylprednisolone acetate) + 120 mg Citanest® (procaine hydrochloride) were parenterally administered into the subacromial region of 28 patients (17 female, mean age: 48 years; 11 male, mean age: 52 years) from a group of patients who have been suffering from shoulder pain for a period of at least two months and had received no benefit from previous treatments. Simultaneously, they were placed on a home-based shoulder exercise programme. The patients were seen two months later and questioned about their conditions. The data were evaluated together with clinical findings based on the range of motion (ROM) of the shoulder. Results: Twenty of 28 patients (71.42%) reported complete relief from pain, 5 patients or 17.85% stated that they had only partial relief of pain, and 3 patients (10.71%) said that the level of pain remained essentially the same. Nineteen of 28 patients (67.85%) had good to excellent ROM while 3 (10.71%) still manifested poor ROM. Conclusion: Local corticosteroid plus local anaestethic therapy together with home exercise programme was found to be an economic, effective and safe short-term treatment in the management of painful shoulder conditions arising from certain disorders.

ARCHITECTURE AS A KNOWLEDGEBASED TOOL:: THE ARCHITECTURAL TRANSFORMATION OF WORKSPACES

In these early days of the twenty-first century the pace of innovations in technological developments is phenomenal. A common example: the personal computers that we were using five years ago – which did not even exist about twenty five years ago – are now –for all intents and purposes useless today. The speed of technological innovations and product development has reached such an extent that almost every one of us has some outdated "technological” tool, which is yet to be "upgraded” to the latest technology. While many disciplines are in constant state of inquiry – both for understanding the factors that necessitate these fast paced developments, and ways of supporting and utilizing the developments themselves, is architecture merely accommodating these technologies – i.e., is it simply a "spectator”? Or, can architecture be a discipline or realm to support these fast paced technological developments and innovations, - i.e., is it a "player”? Which role is more appropriate for architecture, or which positions for architects can highlight architecture as an important force of this era of constant and rapid technological change and development

A Comparative Analysis for Land Utilization：Steel and R/C Interlaced Structures

In architecture, interlace structural concept is considered as a new design approach for cosmopolitan cities with high density to minimize the land use and increase the interaction. With various architectural approach, land resources can be minimized by this interlace concept for residential complexes. Such buildings will eliminate the reduction of land resource problem and on the other side safety measures in structural design is incorporated by interlace concept of buildings. This new concept can be constructed steel or reinforced concrete. In this paper, an analytical approach has been presented for these buildings in architecture and structural design. In the research, design considerations were taken for interlaced structures with reinforced concrete and steel. Components of steel structure, isolated footing, and columns. This paper is presenting a step wise process for interlance structures. They are identification of project area, layout and model preparation, analysis and design of concrete interlaced structure, analysis and design of steel interlaced structure, drafting of the plans and costing and estimation of the structures. Comparison of both reinforced concrete and steel structures were carried out. The main aim of the paper is to provide a comparison between steel and concrete interlaced structure. A cost estimation was carried out to determine optimum design and construction for interlaced structures
