In recent years, temporary housing built in a stricken area has been built by steel construction. But temporary housing could not be built unless an engineer went to a stricken area and the building could not carry a short-time loading like an earthquake or wind loadings. This research aims to develop the permanent box unit construction which is carried and assembled a part by victims. Analysis model used the vinylon fiber reinforced concrete in order to make a concrete ductile without using a reinforced rod. The linear model was analyzed with FEM software. The analysis was carried out and the validity of a temporary housing was confirmed.

Purpose: This study aims to determine the factors that cause inundation/flooding in Cemarajaya Housing, evaluate existing drainage channels and plan drainage channels for unbuilt blocks and analyze the capacity of the drainage system using the EPA SWMM 5.1 program.
Design/methodology/approach: Based on the simulation results using SWMM, the subcatchment response shows that an average of 22.11 mm per subcatchment is infiltrated and the rest becomes runoff of 310.23 mm.
Findings: The abrasion disaster that hit the north coast of Karawang, especially the village of Cemarajaya, had occurred from around 1990 to 2016 and the most severe occurred in three hamlets, so residents affected by the abrasion had to be relocated to a place far from the shoreline. The Department of Public Housing and Settlement Areas of Karawang Regency built a housing estate to relocate residents affected by the abrasion disaster.
Research limitations/implications: In this housing, 299 units of infiltration wells were built because the calculated channel dimensions were not possible to build due to the limited land area of the road.
Practical implications: The problem that occurs in the housing is that the area where the housing construction is located is in the yellow zone based on the Karawang City/Regency Sanitation Strategic (SSK) data in 2017, which is an area prone to inundation of 25% to 50%.

Full textAbstract:
In the wake of the housing market crash in the United States in the late 2000s, images of abandoned homes on the periphery of American cities dominated international media. Mexico continues to face a housing crisis that began at the same time, and the media similarly focus on the high rate of housing vacancy in the urban periphery. The vacancy rate is extreme in many newly built subdivisions in Mexico, yet it is also high in most central cities. In this article, I describe the role of government mortgage lending in housing vacancy rates, across and within cities in Mexico. I do this using data from the 2010 Census of Population and Housing for the 100 largest cities in the country. Cities with more housing built under the federal housing finance system have higher vacancy rates overall, and the relationship is strong in central areas of cities as well as the urban periphery. These findings imply that policymakers should not only be concerned with vacancy in newly built suburban developments, but they should also consider how the expansion of credit for new suburban housing has played a role in the hollowing out of central cities. The article has direct implications for Mexico and raises questions about the frame for debate about housing policy internationally. The structure of housing finance systems is often under-scrutinised. Scholars working in emerging markets should work to identify incentives in finance systems and how they shape urbanisation.

Full textAbstract:
Housing renovation is a common concern to owners, tenants and to society at large. In addition to the high economic costs, the implementation of housing renovation usually have a long-term impact on the society and the built environment. This is a theoretical paper that develops a system model for understanding sustainable housing renovation as a system phenomenon which has multiple sustainability goals, complicated dynamic processes, diverse actors, and a sophisticated institutional environment. It identifies the key challenges of a sustainable housing renovation system, namely the conflicting sustainability goals and the conflicting stakeholder interests. To address these two challenges, the paper suggests an innovation approach in which the process of innovation (linear versus organic) and the typology of innovation (product versus process and business versus social) toward sustainable housing renovation are discussed.

Buana Property is one of the developers in the housing sector or is engaged in the business of selling, buying, and renting property. Advances in technology make Buana properties that always want to grow and be better known in the community with the construction of a mobile commerce system. So far, the system at Buana Properti is still a physical store that is offline so it is not well known to the public, there is no housing sales information system that uses a mobile web system. Therefore, this system is needed to simplify the process of selling housing at Buana Properti Medan which makes it easier for buyers to make house purchases at Buana Property. The system built will also provide a home search feature where this search feature is built using the String Matching method with the Knuth-Morris Pratt (KMP) model. The system that has been built itself uses HTML and PHP programming languages in building mobile web and MySQL as a place database storage. The results of this study are that this system can assist buyers in finding homes that match their wishes and make purchase and payment transactions more easily.

Full textAbstract:
Understanding the spatial pattern of urban house prices and its association with the built environment is of great significance to housing policymaking and urban planning. However, many studies on the influencing factors of urban housing prices conduct qualitative analyses using statistical data and manual survey data. In addition, traditional housing price models are mostly linear models that cannot explain the distribution of housing prices in urban areas. In this paper, we propose using geographic big data and zonal nonlinear feature machine learning models to understand housing prices. First, the housing price influencing factor system is built based on the hedonic pricing model and geographic big data, and it includes commercial development, transportation, infrastructure, location, education, environment, and residents’ consumption level. Second, a spatial exploratory analysis framework for house price data was constructed using Moran’s I tools and geographic detectors. Finally, the XGBoost model is developed to assess the importance of the variables influencing housing prices, and the zonal nonlinear feature model is built to predict housing prices based on spatial exploration results. Taking Shenzhen as an example, this paper explored the distribution law of housing prices, analyzed the influencing factors of housing prices, and compared the different housing price models. The results show that the zonal nonlinear feature model has higher accuracy than the linear model and the global model.

The comfortable housing project for low-income urban residents possess many special characteristics such as large numbers, dispersed distribution, the large-scale of construction, urgent time schedule and strict requirement of high quality. To ensure reasonable period and construction cost, it is also necessary to reform and innovate the way of construction management thinking and working methods. Pre-control measures of construction quality are put with emphasis on transforming passivity supervision into initiative forewarning. Management efficiency of the comfortable housing project can be enhanced. The comfortable housing project for low-income urban residents is built into environmental project taken to develop energy-saving and ground-saving residential in our country. It is a realistic and sharp contradiction that construction enterprises are pursuing profit when indemnificatory housing constructing is weak of profit, and that it is an easily occurred problem that the quality of indemnificatory housing is not security. In this paper, based on the six sigma quality management the Quality Assurance System of indemnificatory housing is put forward, which can be regarded as guidance for construction enterprises.

Land use and transportation system are the main components of the city space structure formation. Settlements as the biggest land allocation in the region play an important role in the availability of human resources and the largest generation of the city. Various problems arise along with the development of urban residential settlements, generally, occur in middle-scale cities to the larger cities i.e. development of middle-class house to elite-class that formed into gate. That fact was one of the causes of transport system problems, non-integrated in the transport system in housing area cannot be avoided. Therefore, this paper explains: 1) current condition of the house built by the developer (gated house) and the self-help house, 2) transportation systems that support the residential area, and 3) concept which supports housing and transportation system alignment in the context of green concept.

Full textAbstract:
One of the key objectives of the formation and development of integrated business structures in Russia is to meet the population's need for new housing. Qualitative and quantitative indicators of residential building commissioning are significantly influenced by demand and supply factors. With the purpose of forecasting the activity of demand in the housing market with the help of methods of economic and mathematical modeling, the interrelation system of factors forming the socio-economic basis for the development of integrated business structures in construction has been built. The formulated economic and mathematical model allowed us to identify the factors focused on the formation of rational relations between the subjects of the housing and construction cluster. The model shows that the effectiveness of the mortgage lending system (from the demand side) and the level of introduction of innovations in the investment and construction complex (from the supply side) have a decisive influence on the solution of the housing problem.

Full textAbstract:
This project was initiated by the Built Environment Faculty at Southampton Institute to investigate the multi-disciplined nature of the problems in System Built Housing (SBH). The intention was to looj at the situation from a wide angle using a compatrative study. Problems on SBH estates are evident in many European countries. In the attempt for a holisitic approach to the wide range of issue involved, the topic was accessed from an urban design perspective besides the focus on housing. Valueable information was derived from conducting the researhc in two countrys, Britain and East Germany. It was possible to examine the SBH estates in two places with distinct histories, cultures, traditions and mentalities of the people. An objective of this thesis was to comapre an urban problem in the context of an eastern and western European country. The data collectiion fort this research departed from the general issues. The more it progressed the more specific and detailed became the information. First the background of the research issue was explored including the recent history of each country, the political and economic context as well as an overview about the construction systems. Furthermore SBH estates were placed in an urban design context by examining their disticnt patterns which break with the principles of traditional city planning. A questionnaire survey was conducted to investigate the attitudes towards SBH expressed by professionals and tenants as the main groups of housing actors. Open-ended questionnaires allowed a comprehensive interpretation of the situation based on the viewpoints of the respondents. The technique of cognitive mapping assisted in drawing a problem picture from the survey findings. Case studies were then used to study the situation on selected estates in detail. Interviews with housing experts in the four case study estates revealed insights into the process of decision making. Commonalities and differences between the countries were explained in the light of local and central government policies, national traditions and people's perceptions. Special attention was drawn to the urban context of the SBH estates compared to the overall city structure. Advice was given to decision makers how to achieve better effectiveness of housing regeneration schemes and to create sustainable residential areas which are appreciated by the people who live in them. Interactions between the characteristics of urban environments, the socioeconomic context, political influences and the quality of the built structures were discussed based on the knowledge gained in the two countries. This comparative study on SBH estates revealed wider conclusions which are relevant for other problems in the built environment. It illustrated that urban problems cannot be considered in isolation from their context; the same problem needs a tailor-made solution in each situation. The built environment should fill the needs of the people who live in it; they are most directly affected by urban problems and therefore should be in the centre of the decision-making process. This requires a better collaboration and the establishment of a mutual understanding among the three groups of actors: politicians, professionals and users, whatever their different economic and political powers. It is necessary to raise people's awareness of the role of their contribution to decisions about the built environment. Political and economic issues should not be the dominant issues in decision making. Short-sighted and half-hearted policy decisions often waste valuable resources without achieving a better quality of life for the people. The latter should, however, be the overall aim of all developments in the urban environment. Concerning the academic debate regarding urban regeneration, the applicabilitu of the reseach methodology was assessed critically. Furthermore, the value of introducing a comparative element into research in the built environment was discussed.

Millions of people around the developing world struggle to obtain safe, decent and affordable housing. The United States of America has substantially improved the residential construction sector by engineering new materials and developing efficient systems in wood construction.
The goal of this research was to assess the potential of introducing system built wood construction system manufactured in the United States in urban social housing markets of developing countries. Peru, Ecuador and Colombia were three countries chosen for this study. Stakeholders in social housing in these three countries were interviewed to assess key aspects of traditional construction, current social housing deficits, perception of wood use in construction, and policies associated with social housing in selected markets. Findings indicate developing custom housing products for urban social housing programs can provide access to this untapped markets. Awareness about wood construction was very limited in the studied region. System built wood construction manufacturers in the U.S. were assessed to identify barriers and incentives for internationalization. Manufacturers in the U.S. also identify the need to expand their existing customer base. Findings of the survey conducted among the manufacturers identified various barriers to export. This research contributes to opening of new markets for exports of prefabricated wooden buildings in new geographical regions.Master of Science

Full textAbstract:
In 2017, the Saudi Arabian Government through its Ministry of Housing, announced that it planned to build 1.45 million affordable houses by 2030. The government will contribute to the cost of the houses to put them within the price range of people with modest incomes. Central to achieving this goal is the use of innovative, high-tech construction methods, mainly 3D printing. Several prototype houses have been constructed and more are planned to give Saudis an opportunity to experience them first-hand before a decision is made to go ahead with the planned rollout. The motivation for this thesis was to better understand the likely success or failure of this ambitious scheme. Early research soon revealed that since the discovery of oil in the kingdom in 1938, there have been many thousands of houses and apartments built through government-sponsored affordable housing projects. All have embodied a mixture of imported western notions of domestic living combined with traditional Saudi cultural, social and religious values and practices. The construction of these large-scale projects has relied on, and to a large extent been driven by, the use of imported construction materials, techniques and expertise. To better understand the current masshousing plan this thesis, through the study of examples and case studies, explores these projects from both a technological and a qualitative perspective. The aim is to provide insights into their successes and failures in the hope that lessons can be learned that will help guide the current proposal towards a fruitful outcome for the Saudi people for whom the houses are intended. Prior to 1938, domestic buildings in Saudi Arabia were constructed by local craftsmen using traditional materials and techniques. The first modern buildings were, flat-packed, timber houses manufactured in California and imported by the Standard Oil Company of California (SOCAL) to accommodate their expat oil workers in the rapidly expanding camp at Dammam on the Arabian Gulf. A trickle soon turned into a flood with many thousands of prefabricated timber houses from America and Europe imported into oil compounds all around the country. While these houses were never accepted more widely by Saudis as suitable domestic dwellings the modernist, technological thinking they embodied undoubtedly translated into the first contemporary, non-traditional houses built outside the camps during the 1950s designed by architects and engineers employed by SOCAL’s successor company Aramco. Mass-housing projects for the wider Saudi community soon followed all of which were constructed with heavy concrete construction. The first examples were built in situ however by the 1970s industrialised prefabrication had become established as the dominant method of delivering thousands of identical, affordable houses and apartments. Many were initially unappealing to Saudi house and apartment buyers and stood empty for a number of years. When the houses were finally occupied their new owners expressed their dissatisfaction with the manifestation of imported ideas about how they should live by almost universally carrying out modifications. These range from the relatively minor, raising the height of boundary walls, to major changes including adding a second storey. It is extremely difficult for the untrained householder or the local builder to alter and modify a house constructed of factory-made, loadbearing precast concrete panels and the same will be true for 3D printed houses. For the 1970s precast houses, modifications resulted in a significant number of structural failures leading to abandonment of the house. In addition, eclectic streetscapes emerged consisting of an assortment of styles and building materials some of which attempt to recreate a resonance with vernacular modes of living. Some houses are modelled on the latest trends found in architectural and lifestyle magazines. If minimising this level of modification is accepted as a goal for the proposed 3D printed houses, then a detailed understanding of previous industrialised mass housing schemes is important.Thesis (Ph.D.) -- University of Adelaide, School of Architecture & Built Environment, 2021

Since the 1990s, the Taiwan government has introduced the concept of intelligent build-ings and has led building facilities toward being automated, remote control based, and convenient. In order to link Taiwan architecture with the world trend of environmental protection, energy conservation, and technology humane, and correspond with having the reputation of being a technology island, starting from 1992, Architecture and Build-ing Research Institute of Ministry of the Interior facilitated a series of intelligent build-ings related research, and established the "Intelligent building Standard Mark” certifica-tion system as the regulation reference for construction industries. Also, this measure-ment gave consumers with the intention of home purchase another quality choice. When there is a need for a certain product, the consumer will search related product in-formation as a reference. Through the process of understanding, these acquired infor-mation will be turned into product knowledge which will give the consumer a better un-derstanding of the product necessity. The price is often a significant external factor for identifying the product quality. This means the purchase intention of the consumers will be affected by the amount of product knowledge that they have. Those consumers with less product knowledge will regard a lower price as being equivalent to a lower quality. For them, there would be more hesitation in their purchase intention of lower-priced products. Thus, the purchase intention of consumers on a product will be inter-fered by various factors that affect consumer behavior. And it also includes many physical and mental factors that affect consumer behavior during the purchasing proc-ess. The overall cost for a house can range from millions of NT dollars to more than hundred million NT dollars. This is a huge investment amount compared to other products, and is not an average, daily commodity purchase. To lower the error rate during decision-making, the consumer decision-making needs to be more careful com-pared to purchasing other products. This research is conducted with literature study, questionnaire survey, and statistical analysis. The main purpose is to explore the effect and difference of intelligent build-ing systems and facilities implementation on the intention of home purchase of consum-ers. This is also to understand the actual thoughts of consumers and to provide the fu-ture direction for the construction-related industries. Through the research analysis, the results indicate that product knowledge, purchase intention, and consumer behavior all have significant impact on the intention of home purchase of the consumer, which means that consumer behavior on home purchase will be affected by the factors such as needs, price, practicality, … etc. Naturally, their decision-making will include con-cerns and detailed assessments in all levels.

AbstractThis chapter examines household energy practices in the ecological housing cooperative Klosterenga in Oslo, Norway. Klosterenga, built in 2000, was one of the early implementers of smart building principles in Oslo, Norway. Although the ecological profile of Klosterenga inspired some of the residents to change behavioural habits such as limiting their car use or consumption patterns, the findings of this article show that expectations of smart technology as a primary solution towards energy efficiency and residents being rational consumers using this technology to save costs do not hold. The residents of Klosterenga rarely emphasised the building’s ecological profile and smart energy systems when purchasing their home, and the energy-efficient systems and integration of heating costs in the rent had adverse effects on residents’ energy consumption. Rather than taking the visions of ecology at heart, many residents legitimised everyday habits of high indoor temperature in the fact that the system was efficient. The findings contribute to the growing body of research that critically examines how smart technology visions for reducing energy use in buildings are implemented and practiced by the residents living in them.

AbstractWith BS 1192:2007 and even more so with BS PAS 1199-2:2013 and 1192-3:2014, the concept of Common Data Environment (CDE) of the order (project, construction or management that is). Originating from a standard dedicated to design (BS 1192:2007) and although its concept has been extended to information management in general: Capex (strategy, project, construction: PAS 1192-2) and Opex (exercise: PAS 1192-3), the CDE, as it is understood today in common practice, is still very much affected by the original link with the design and the design phase (and in particular the design in the new building). All this according to an information flow that is still very linear and sequential: client, designer, builder, manager, user; more than circular, as the so-called BIM methodology would like. The risk, therefore, is that the commercial software market is affected by this CDE approach, which is also useful for the very rich real estate market of the emerging economies, neglecting the construction market of the more consolidated economies (Europe for before), very built up, and aimed more at housing quality, sustainability, reuse, and renewal of the existing heritage rather than the new one. It is consequently necessary to define new information flows and a new type of information management environment (CDE) for the phases of use, conservation, and renovation of buildings for the European market. The need arises for a specific BIM Management System (BIMMS, overcoming the classic CDE) for asset management and their enhancement that collects information from the buildings themselves and its users (Digital Twins, IoT, sensors, etc.). A new CDE / BIMMS that uses semantics and open dialogue, via API, with multiple Tools rather than acting as a repository of files and models. BIMMS is a new concept of CDE created for the operation/renovation phases in mature real estate markets (such as the European one).

Full textAbstract:
AbstractThis chapter focuses on the reception system for migrants, a system that consists of procedures that take place between practices of what is known as first reception and longer-term plans for integration. When we use the term migrant in this chapter, we are referring to those who migrate towards a territory, have arrived at a territory, or live in the territory in question for a short or long period of time. Unless noted otherwise, the term does not distinguish between migrants, asylum seekers and refugees. Our research is built on an analysis of two key periods that are critical in the emergence, evolution and consolidation of this intermediary space. Firstly, at the start of the 2000s, reception emerged as a concept and practice related to the governance of so-called transit migration. This period was characterised by a plethora of complex forced and voluntary mobilities inside Greece and the EU. Furthermore, during this period, the state of ‘being in limbo’ became established as a situation in between borders, as well as in between transiting (through) and settling (in) a territory. During the second key period from 2015 to 2019, we observe contradictory policy attempts to consolidate migrant reception as a formal system, including new infrastructures like camps and housing programmes, which were maintained by diverse agents and jurisdictions. The ‘hotspot’ approach, the closing down of the Balkan route and the EU-Turkey Statement constituted important impediments to the development of inclusive practices by international humanitarian agencies and grassroots solidarity initiatives.

Full textAbstract:
This chapter details how Mayor Michael Bloomberg celebrated successes and suffered defeats when it came to low-income housing. It mentions 165,000 units of affordable housing that Bloomberg built or renovated during his three terms, a record surpassed only by mayors Fiorello La Guardia and Ed Koch. It also reviews the highly sophisticated system of financing that Bloomberg created to accomplish his feat on housing, which included funding the New York City Housing Trust Fund. The chapter recounts the establishment of the New York City Acquisition Fund that built affordable though not necessarily low-income housing, providing developers financial incentives through various federal and state programs. It highlights the housing policy in which Bloomberg suffered his greatest defeat as he lost more low-income housing than he built.

Full textAbstract:
This work is part of a research into the state of conservation and behavior of a group of self-built social housing. The construction, which dates from 1990, was carried out with an original low-cost construction system that uses clay and wood bricks called LAD-MA. This was implemented by the NGO Urban Technical Assistance Center “Taller Norte”, in the Peñalolén commune, Santiago de Chile, Metropolitan Region. The study focuses on the evaluation of well-being and thermal comfort in these homes, which is determined through environmental monitoring by meteorological stations installed for six months in 4 homes. It is established that the houses do not comply with the parameters set up by the international standards ISO 7730 and ASHRAE 55. For this, constructive solutions are proposed to thermally improve the current houses, and update the LAD-MA construction system to comply with the thermal Insulation standards stipulated for the Sustainable Housing Certification of the Ministry of Housing and Urbanism.

This chapter discusses the development of an experimental “Ordinary” scheme built under the provisions of the 1946 Housing Act. The experiment was a district central heating system, which predicated high rents. Tenants were largely self-selecting in that they had to have enough regular income to pay these high rents. But the houses were built in tenemental form with flat roofs, and there were numerous complaints about poor noise insulation and leaks. Although its external perception was “élite,” it was still a substantially skilled manual working-class scheme, but one with several active voluntary organisations, and very popular with its tenants.

RM Daley mobilized Chicago police, the Cook County courts, and state prisons in a massively punitive assault on crime. This deflected attention from teardowns of housing projects RM’s father built and from the absence of replacement housing in hyper-segregated neighborhoods. RM shifted attention to “gangs, guns, and drugs,” tightening a criminal justice system aligned with the “politics of punishment” of the Reagan era. Residents of some Latinx neighborhoods, such as the Little Village, perceived the city as supporting their aldermens’ crime prevention efforts, yet there was little evidence that Daley’s disorderly conduct arrests, automatic transfers of juveniles to adult court, new gang loitering ordinances, and dramatic increases in arrests and punishment prevented crime in segregated Black neighborhoods. These repressive interventions increased legal cynicism in residentially segregated Black communities and in many Latinx neighborhoods. Black electoral support for RM Daley also declined. We introduce an “exclusion-containment theory of legal cynicism” to explain this.

Full textAbstract:
Chapter 4 explores the most significant dynamic of building and construction, that is, the speculation in land and real estate. It is particularly evident with the emergence of super-rich enclaves in cities, and the construction of buildings only affordable to wealthy investors. In major cities, like London and New York, the construction of, primarily, residential buildings is part of a broader process of creating investment portfolios. Such properties are less to be lived in and regarded more as economic assets that enable global investors to accumulate wealth. This phenomenon is part of a casino capitalism in which the built environment is regarded as comprising tradable objects, to be exchanged as part of a system of technocratic asset management. In the chapter, the significance of ‘building as assets’ and the impacts on the socio-spatial development of cities is discussed, including pricing people out of local housing markets and rendering neighbourhoods as ‘dead zones’. Buildings are built but rarely inhabited, or are part of a daytime economy that, at best, includes partial human presence and, at worst, perpetuates ‘ghost places’.

Full textAbstract:
This chapter presents evidence gathered from the comprehensive regeneration of Myatts Field North (MFN) estate in Lambeth, originally built in the mid-1970s as part of a slum clearance and area improvement plan. A first section contrasts the original promises made to residents by the council with the eventual 25-year, £272.4 million contract signed in 2012 with Regenter Myatts Field North Ltd (owned by Pinnacle and John Laing). Under the scheme, 305 homes have been demolished and rebuilt, 172 homes have been refurbished by Rydon, and 503 new private flats have been built outside of the PFI contract. A second section documents the extraordinary number of defective works and services that plagued the refurbishment and new housing. A third section focuses on residents’ appalling experiences under a district heating system run by energy giant, E.ON, that broke down 48 times in four years yet some residents could not afford to use it. A fourth section then discusses the betrayal of some of the homeowners who had been originally guaranteed a new home on the estate but were forced out. A fifth section ends by explaining the safety defects discovered after the Grenfell fire.

Full textAbstract:
This chapter explores how the different arrangements of low- and middle-income housing at the micro-level relate to processes of city building at the level of the city-region. We study how the social and economic contestation on the uses of urban land translate into new spatial patterns of urban and regional development. This is concretely done through a comparative case study of a Brazilian and an European city-region. This comparative perspective will sensitize the empirical investigation to the effect of the (changes of) institutional context and regimes on housing arrangements and spatial patterns of city building. A specific focus will be on self-building arrangements as practices that challenge existing formal systems of city building in both cases.

Full textAbstract:
Rotary compressor has been widely used in room air conditioner. During development of the new compressor, the abrasion of bearings and the break of crankshaft frequently occurred. So it is very important to build a numerical method to estimate the reliability of the compressor. The rotor-journal bearing system is numerically solved as a dynamic nonlinear fluid-structure interaction problem in this paper. The finite element models of the rotor and bearing housings are built up by using the Timoshenko beam model. In order to get the oil film pressure of the journal bearing, Reynolds equation is solved by variation principle, and the finite element method is used to discrete the oil film. An iterative method based on the complimentary principle is used to solve the oil film force and the Reynolds boundary simultaneously. Through analysis, the abrasion position between the bearing and shaft is presented, and the bending tension stress shows the dangerous sections of the crankshaft. Through the distribution of the oil pressure, position of the screw oil groove, which is built on the inside of the bearing housing to supply the oil to lubricate the bearing, is determined. The proper position of the radial oil hole on shaft is decided by analysis of the bending tension stress.

Full textAbstract:
The cylindrical filters presently used in <1000 m2 drip irrigation systems are frequently clogged, increasing pressure loss and lowering the flow rate through the filters. This work investigates the mechanisms for this clogging and proposes an alternative filtration design that would enable both more reliable and lower maintenance filtering. This proposed system is compatible with existing drip irrigation systems and could be made inexpensively with plastic bottle manufacturing equipment. To compare the proposed design to off-the-shelf options, a drip irrigation test setup was built to measure the pressure loss across different filters as particles accumulated. These experiments confirmed that pleated cartridge filters, with high effective surface area, incurred lower pressure losses than cylindrical filters. These tests revealed that the greatest reason for clogged performance was that filtered particles (not the cartridge filter itself) eventually restricted the flow of water through the system. This inspired the redesign of the filter housing such that the housing extended far below the filter, providing a catch basin away from the filter for the particles to settle. Fixing the filter independently of the bottom casing significantly improved the overall performance of the filtration system, reduced the maintenance requirement necessary from the user, and would enable inexpensive manufacturing via blow molding. This paper experimentally demonstrates that the cartridge filter inside the redesigned housing can filter out over 2 kg of sand while maintaining less than a .03 bar pressure drop across the filter at a flow rate of 25 l/s.

The article analyzes the current state of environmental monitoring of atmospheric air near the construction or repair and construction works of the urban environment. The main direction of environmental monitoring in the context of local construction, i.e. the construction of housing complexes, micro districts where the construction site borders on already built and populated residential buildings, should be the control of air pollution, where special attention is paid to fine dust. Reliable monitoring of dust pollution in construction zones and adjacent territories is an important goal of improving the environmental safety of construction production.

Full textAbstract:
The lighting systems of homes and workplaces today must be constantly redesigned to be environmentally friendly, sustainable, healthy and ergonomic. This requires maximizing the flow of daylight into indoors, minimizing the amount of pollutants used in their manufacture, long durability materials considered in the design, maximizing energy efficiency of the lighting system components, mimicking the spectrum of natural light and providing some control of lighting modes by the user. Taking into account all these considerations, it is proposed the design and construction of an intelligent lighting system that regulates the use of natural and artificial light, prioritizing the availability of the former over the latter in order to be implemented in housing in the region of the Yucata´n peninsula. To achieve this goal, it is designed and built a light sensor with its own signal conditioning circuit, a light tube of stainless steel with luminous flux control, a dimming circuit for a lamp that uses light-emitting diodes (LEDs) and a control system with a PIC18f4550 micro controller.

Full textAbstract:
<p>Conventional single family houses in Poland are being built in the improved traditional construction technology with massive load-bearing structure created by masonry walls made of ceramic , silicate or aerated concrete blocks, concrete foundations, concrete rib-and-slab floor and pitched timber or concrete flat roof. Expanded polystyrene and mineral wool are being used as thermal insulation. Such solution is very time- consuming and costly due to more and more expensive manpower. The change in economy from communism to free market caused the beginning of modern thinking about construction technology for family house to be light, eco-friendly, innovative and low-cost. The definition of the term “affordable” in relation to single family housing, as well as the socio-economical background for the low-cost housing in Poland is presented. The paper presents proposal of low-cost family house construction built in light steel frame technology. The supporting structure is composed of steel frame made of cold-formed galvanized C shape profiles. Externally the steel frame is covered with cement bonded particle boards, covered with polystyrene insulation and finishing coat according to ETICS system. From the inside the steel frame is covered with plasterboards. The main thermal insulation of the building is created by mineral wool filling the interior spaces of walls, ceiling and roof panels. Comparison of the total construction costs of a 136 sq m building made in light steel frame technology with buildings of identical dimensions made in other, popular and available traditional technologies showed that a steel technology is approx. 10-20 percent cheaper. The paper presents also the comparison of the low-cost model steel structure houses worked out in Czech Republic, Portugal, Romania and Brazil, including technical parameters, structure type and cost of erection.</p>

In ASME Turbo Expo 2018: Turbomachinery Technical Conference and Exposition. American Society of Mechanical Engineers, 2018. http://dx.doi.org/10.1115/gt2018-75876.
Full textAbstract:
On two-shaft DLE (Dry Low Emissions) gas turbines compressor air is often bled off the combustor housing to control the combustor flame temperature for part load emissions management. The bleed air is typically directed into the exhaust ducting, bypassing the turbine, causing engine efficiency to decrease. A prototype bleed air recirculation system was fitted onto a compressor package in the field that redirects bleed flow from the engine exhaust to the air inlet to raise the air temperature entering the engine. This system is designed to reduce the amount of bleed air required at a given ambient operating condition, while not compromising emissions, to increase part load efficiency. The bleed air recirculation system was designed, built, installed, and tested on a Mars 16000S compressor package at a station in northern Pennsylvania. A control algorithm was developed and validated to control bleed air recirculation so that package durability was not impacted. Over an evaluation period of 12 months, no significant durability issues or degradation were noted. The on-site evaluation indicated that the engine’s heat rate is significantly improved by using bleed air recirculation. The heat rate was reduced by as much as 7% during testing at site with a strong dependency on the engine operating load and ambient temperature. As predicted the best case was demonstrated at 50% load and at colder ambient conditions. The NOx emissions were also improved with bleed air recirculation. In addition, using this system extended the range of low emissions operation to lower loads. No effects on compressor surge or sound emissions were detected.

Full textAbstract:
Effects of the exhaust of a coal fueled gas turbine combustion system on turbine hot section materials and coatings are being determined. A system has been developed to evaluate currently used turbine materials and coatings exposed to coal combustion exhaust. Using an engine to test these materials is not feasible due to the inordinately expensive fuel costs associated with running the engine. Therefore, a scaled-down Hot End Simulation Rig (HESR) was designed and built to economically evaluate turbine components operating with a coal-water mixture (CWM) flow rate of 3.8–7.6 liters/hour (1–2 gallons/hour). The rig incorporates primary and secondary combustion zones, a ceramic barrier filter, and a housing for the material samples. Cooling air is metered to the samples to simulate the material temperatures of subsequent turbine stages. Because of the small scale of the rig, much development focused on the design of an adequate fuel injector that would operate reliably for long periods without plugging. Long-term testing is planned to subject the test specimens to coal exhaust using the alkali level in the fuel as the principle variable. An initial level of 300 ppm is used for a 1000 hour preliminary test. The design, development, and test procedure of the HESR are discussed.

Full textAbstract:
This paper presents a Hardware-in-the-Loop (HIL) test setup used for studying the dynamics of an elastomer supported machine bed. The setup uses real elastomer dampers and modeled machine dynamics (process model) connected together via real-time interface. The HIL approach was chosen since the elastomers are a critical part of the system, however, determining their properties for engineering needs can be a challenging task. Accurate elastomer models include many parameters that can only be determined by experimentally, and even then their implementation for real-life applications is not always practical. Using real elastomers supports in the simulation removes uncertainties associated with classic elastomer models, while simulated process makes it possible to test different scenarios fast and with good repeatability. The process model includes a description of the machine body, a rotating unbalanced drive mechanism creating cyclic loading and external excitation forces acting on the machine. The method enables testing of machine bed supports in a realistic operating environment. A test rig was built for housing the elastomers incorporating a hydraulic actuator for producing the process movement. The hydraulic circuit was designed for good dynamic performance with predictive control to minimize delays in the real-time interface. It was found that the HIL-setup can provide fast and accurate information about the plant model behavior in different operating scenarios using the elastomer supports.

New developments in instrumentation for ocean environmental engineering are allowing unprecedented levels of trace contaminant measurement in the deep ocean. With funding from the U.S. National Science Foundation (NSF), our engineering design team constructed a new mass spectrometer-based in situ analysis system for work in the deep ocean environment over prolonged deployment periods. Our design goals were a depth capability of up to 4,000 m water depth (400 bars hydrostatic pressure) and autonomous operation for periods of up to six months to a year, depending upon the type of external battery system used or other deployment circumstances, e.g., availability of a power cable or fuel cell power source. We chose a membrane introduction mass spectrometry (MIMS) sampling approach, which allows for dissolved gases and volatile organics introduction into the mass spectrometer vacuum system. The MIMS approach and the hydrophobic, silicon-coated membrane chosen both draw upon our previous experience with this technology in the deep ocean. The membrane has been tested to 400 bars in a series of long-term hydrostatic pressure tests, which extend the 200-bar working depth rating of this membrane by a factor of 2. Long-term deployment capability of the moderately powered, approximately 100 W system, was accomplished by power management of the embedded computer system and custom electronics with Windows-based and custom software now fully-developed and bench tested. The entire system fits within a 6.5-inch outside diameter pressure housing that is approximately five feet long. It consists of a 1 to 200 amu range quadrupole mass spectrometer equipped with Faraday and electron multiplier detectors, compact turbo-molecular and backing diaphragm vacuum pumps, internal rechargeable batteries, and internal waste vacuum chamber. Sample routing past the MIMS is accomplished by computer-controlled solenoid valves. We designed the pressure housings of both 6AL4V and type 2 titanium alloys that are rated to working depths of >4,000 m and are essentially corrosion proof over long-term deployments. We designed and integrated a fail-safe valving system for both rapid response to high-pressure MIMS failure and a pressure-switch circuit and high-pressure solenoid valve to detect and protect against slow leaks of the MIMS. To route sample waters to the MIMS-based instrument, we also designed and built a rugged plastic plenum that couples to the face of the sampler head, the latter of which consists of the MIMS inlet and a full-ocean rated thermister temperature probe with an operational range from −5 to 50°C. These instrumentation innovations will be described in the paper.

Full textAbstract:
The global pandemic has brought renewed attention toward the everyday challenges in informal settlements. COVID-19 reminds us that southern urban life is rooted in ‘collective’ experiences where toilets and kitchens are shared by multiple families; where the categories of work and home, private and public space overlap; and where the majority live in vulnerable conditions. Despite these challenges, some of the most innovative and collective responses to COVID-19 have emerged from these areas. While informal settlements did face a host of risks and vulnerabilities during the pandemic, local responses have highlighted the resilience of informal settlement communities. However, few informal settlements are actually ‘resilient’ and any local responses must be robustly supported by system-wide change including support from local and national governments, improvements to built infrastructure, and improved access to health care services, among other priorities. The category of ‘informal settlements’ also captures a wide range of settlement types, from a legal slum to an informal settlement with no legal status, with many other types in between. This underscores the need to address fundamental issues that ‘perpetuate conditions of inequity, exclusion and vulnerability’ while also recognising the needs and contexts of different kinds of informal settlements. Whether COVID-19 helps governments recognise conditions of insecurity and vulnerability to address safe and secure housing and infrastructures remains to be seen. This is an update to the previous SSHAP brief on ‘COVID-19 in Informal Urban Settlements’ (March 2020). This evidence review highlights local responses, grassroots efforts, and challenges around COVID-19 recovery within urban informal settlements in South Asia. It focuses on specific examples from Karachi, Pakistan and Mumbai, India to inform policy responses for COVID-19 recovery and future epidemic preparedness and response. We show how local level responses are shaped in these cities where national and international responses have not reached communities at municipal and sub-municipal levels.
