A survey of the seismic hazards for about 30,000 nonresidential buildings in Portland, Oregon was conducted, and an earthquake damage and loss estimation model was developed. To conduct the buildings survey, ATC-21's Rapid Screening Procedure was used. For each building the data included: address, year built, area, number of stories, building name, use, occupancy type, estimated range of number of people, nonstructural falling hazards, building type, and performance modifiers such as soft story and torsion. Soil data were provided by the Earthquake Hazard Maps published by the Oregon Department of Geology and Mineral Industries. The algorithm set up on the GIS was to compute the structural score based on ATC-21 score, modify the score based on the geologic condition of the site, and finally, compute the damage. The proposed loss estimation model is based on ATC-13, and the scoring system developed by ATC-21. The results are in terms of percent (or dollar) damage to buildings in the survey and loss of life and serious injuries.

This paper demonstrates the concept of disaster resilience through the development and application of quantitative measures. As the idea of building disaster-resilient communities gains acceptance, new methods are needed that go beyond estimating monetary losses and that address the complex, multiple dimensions of resilience. These dimensions include technical, organizational, social, and economic facets. This paper first proposes resilience measures that relate expected losses in future disasters to a community's seismic performance objectives. It then demonstrates these measures in a case study of the Memphis, Tennessee, water delivery system. An existing earthquake loss estimation model provides a starting point for quantifying resilience. The analysis compares two seismic retrofit strategies and finds that only one improves community resilience over the status quo. However, it does not raise resilience to an adequate degree. The exercise demonstrates that the resilience framework can be valuable for guiding mitigation and preparedness efforts. However, to fully implement the concept, new research on resilience is needed that goes beyond loss estimation modeling.

Earthquake loss estimation (ELE) refers to the analysis and study of the possible effects of an earthquake in a region or population and quantifies the consequences of the earthquake. The objective of this study is to provide an insight into earthquake loss estimation for the most common approaches by seeking to survey the current methodologies for quantifying the earthquakes' negative effects. Naturally, peoples search about desirable approaches to estimate of earthquakes costs and losses which are not predetermined to subsist as usual. Other issues related to those approaches are endeavor to achieve the state of art to quantify the earthquakes consequences, the aspects of a building's response to earthquake. The aspects that will be characterized in this research are: 1) Input data like building information (Structure system, location, occupation, etc.), earthquake hazard; 2) Analysis methods; 3) Output data. ELE methods are categorized in different ways depending on one or more parameter. ELE approaches into two groups (1-a shocked building stock in a specific city or settlement, 2-specific building or structure). The varying and common use have been observed when selecting the approaches of this research. The methods and tools that used in the exploration include QLARM, SELENA, ELER, HAZUS, SLAT and FEMA P-58.

Under the situation of energy crisis, air source heat pumps are paid more attention recently. In order to save energy, the feasibility and performance of air source heat pump are studied by experiment, and variation laws of exhaust temperature, evaporator outlet temperature and outlet presser of compressor were analyzed in this paper. Air source heat pump apparatus were set up and the experiment was during 10°C, 20°C, 30°C and 40°C. The results were as follows: exhaust temperature of compressor increases gradually with the increase of tank temperature, but the temperature difference between exhaust temperature of compressor and tank temperature becomes little; temperature difference in evaporator decreases; Compressor outlet pressure increases obviously.

The Relationship

What do growth-oriented business models look like? While several economic theories, such as the theory of the firm, are based on the assumption that firms aim to maximise their profits, past research has shown that growth intention is heterogeneous among firms and that many business owners prefer to keep their firm at a size that they can manage with few resources. This paper explores the relationship of growth intention and business models, based on a sample of 135 German ICT businesses. Following an exploratory approach, Mann–Whitney U tests are applied to analyse how different business model designs correspond with different levels of growth intention. The results indicate that growth intention relates to business owners’ decisions regarding the provision of consulting services, the level of standardisation in offered products and services, the choice of addressed markets, the implementation of competitive strategies based on cost efficiency and of revenue streams based on one-time- and performance-based payments. Furthermore, the results show that growth oriented firms are no more likely than non-growth oriented firms to adapt their business models dynamically to changed internal or external conditions.

This study has been carried out to evaluate the nancial performance of HDFC bank. HDFC was amongst the rst to receive an 'in principle' approval from the Reserve Bank of India (RBI) to set up a bank in the private sector. HDFC Bank is the second largest Private sector Bank in India and one of the top 5 banks in the country. The bank has a network of 5000+branches and 16000+ATMs in 2902 cities/towns. HDFC Bank provides a number of products and services including wholesale banking and retail banking, treasury, auto loans, two wheeler loans, personal loans against property, consumer durable loans, life style loan, credit cards and the various digital products. The nancial performance of above mentioned bank has been evaluated for the past ve years i.e. 2017, 2018, 2019, 2020, 2021. The data analyzed by ratio analysis such as current ratio, liquid ratio, xed assets ratio, debt-equity ratio and net prot ratio and give interpretation to each ratio. To conclude this nancial soundness of the bank is satisfactory during the study period.

In 1997 the Internet was seen by many as a tool for radical reinterpretation of physicality and gender. Cybertheorists predicted we would leave our bodies behind and interact online as disembodied minds, and that the technology would reshape the way we saw ourselves. However, physicality has proved to be an inextricable part of all our interactions. Changing Internet technology has allowed Net users to find a myriad ways to perform and express their gender online. In this paper I consider attitudes to gender on the Net in 1997, when the main concerns were the imbalance between men and women online and whether it was possible or desirable to bring the body into online interactions. In much of the discourse surrounding gender online, a simple binary was assumed to exist. I go on to consider the extent to which those attitudes have changed today. Through my own experience of setting up a women’s community on Livejournal, and my observations of a men’s community set up in response, I conclude that though traditional attitudes to gender have largely translated to the Net and the binary is still the default view, some shifts have occurred. For example, between 1997 and today there seems to have been a fundamental change in perceptions of women’s attitudes to adversarial debate, and an increase in awareness of genders beyond the binary. In addition, experience and preliminary investigation lead me toward a hypothesis that today’s female-identified Net users are engaged in more conscious and active exploration and performance of their gender online than male-identified users are.
