A DESIGN CONCEPT PROPOSAL ABOUT COMPACT LIVING UNITS: USE CASE FOR STUDENT HOUSINGLópez Vallejo, Antonio Taneli January 2016 (has links)
In the recent years around the world there has been a constant increase in the number of students who apply to continue their studies at a higher level, this in turn has brought a great demand in the occupation for student housing. Finding a place to live is one of the issues that new students have to face when moving into another city or country, which can be really challenging at times. The project speculates with a design concept that may help the demands for student housing in the city of Växjö, Sweden. The idea is a housing unit for one person that occupies a space of 13 m2 with an interior space of 10 m2 so it can be moved with a truck to the place where required for a temporary time. The interior proposes an efficient, flexible and comfortable space for the needs in the everyday life of a student. This is done with an organize layout and some multi-purpose furniture that can also be retractable when not in use to save space.

Factors associated with nosocomial fungal sepsis among patients in the paediatric intensive care unit at the Chris Hani Baragwanath academic hospitalAhn, Seung-Hye January 2017 (has links)
A research report submitted to the Faculty of Health Sciences, University of the
Witwatersrand, Johannesburg in partial fulfillment of the requirements for the degree of
Master of Medicine in the branch of Paediatrics and Child Health
29 May 2017 / Introduction
Sepsis, and in particular, severe sepsis, remains a major cause of death in children
worldwide. One of the areas where the burden of sepsis is keenly felt is in the paediatric
intensive care unit (PICU) setting, contributing significantly to childhood mortality.
Fungal organisms have emerged as a major organism contributing to nosocomial sepsis in
PICU. No local data regarding nosocomial fungal sepsis in the non-neonatal, PICU
population exists regarding this matter. This study describes the characteristics of patients
with nosocomial fungal sepsis in the PICU at South Africa’s largest hospital Chris Hani
Baragwanath Academic Hospital (CHBAH).
Methods
This study was a retrospective review of patient records. All patients aged 0-16 years
admitted to the PICU at Chris Hani Baragwanath Academic Hospital (CHBAH) from
January 2008 through December 2011 were assessed. A total of seventeen patients who
developed nosocomial fungal sepsis were included in this study.
Results
The incidence of candidaemia was reported to be 3.2 per 100 cases. The major age group
affected by nosocomial fungal sepsis was the under one age group. The most common
diagnoses on admission were lower respiratory tract infection (LRTI) followed by
haematology-oncology and acute gastroenteritis cases. ICU

corticosteroid use (47%). The penicillin class was the most common antimicrobial that
patients were found to be on at the time of nosocomial sepsis. The most common fungal
organism as a cause for nosocomial sepsis was C. parapsilosis rather than C. albicans.
Furthermore, the majority of this study’s isolates were susceptible to voriconazole rather
the current empiric antifungal of choice, namely fluconazole.
Conclusion
The presence of central venous catheters, arterial lines, mechanical ventilation and
systemic corticosteroid use is common in paediatric patients with nosocomial fungal
sepsis. However, this study was unable to determine statistically significant factors
associated with fungal sepsis in a tertiary PICU due to the surprisingly small number of
cases (n=35) detected over a four-year period. This perhaps represents the most striking
finding of the study together with a concerning pattern of fluconazole resistance (14%)
among isolated organisms. / MT2017

The development and evaluation of a unit testing methodologyLindberg, Stefan, Strandberg, Fredrik January 2006 (has links)
<p>Westinghouse Fuel Manufacturing in Västerås, Sweden, manufactures fuel rods for nuclear plants. Manufacturing-IT is a software development section at Westinghouse Fuel Manufacturing. This thesis involves the development of a unit testing methodology (UTM) for the Manufacturing-IT section, which currently does not follow a well-defined software test process.</p><p>By evaluating different unit testing best practices and UTM design issues collected from literature, articles, papers and the Internet, a UTM document was developed. The UTM document was developed according to requirements from Manufacturing-IT and as an extension to existing documents within the Westinghouse organization.</p><p>The UTM was evaluated by applying the methodology in a case study. A single unit within a production control system in the rod manufacturing workshop at the Westinghouse fuel factory in Västerås was tested. Asides from evaluating the UTM, the case study was intended to find software tools that could simplify the unit testing process, and to test the production control system unit thoroughly.</p><p>The 182 test cases designed and implemented revealed 28 faults in the tested unit. NUnit was chosen to be the tool for automated unit testing in the UTM. The results from the case study indicate that the methods and other unit testing process related activities included in the UTM document developed are applicable to unit testing. However, adjustments and further evaluation will be needed in order to enhance the UTM.</p><p>The UTM developed in this thesis is a first step towards a structured testing process for the Manufacturing-IT section and the UTM document will be used at the Manufacturing-IT section.</p><p>By using the methods and other unit testing process related activities in the UTM developed in this thesis, any company or individual with similar requirements for a UTM as Manufacturing-IT, and that performs unit testing in an unstructured way, may benefit in that a more structured unit testing process is achieved.</p>

Geometry and continuity of fine-grained reservoir sandstones deformed within an accretionary prism - Basal Unit, West WoodbourneBlackman, Ingrid Maria 30 September 2004 (has links)
The Basal Unit of West Woodbourne Field in Barbados is a 250 m thick succession of finely-interbedded sandstones and mudstones deposited by Paleogene, fine-grained, deep-water systems off the northern South American margin and deformed as sediments were translated to the subduction zone of the Caribbean and Atlantic plates. Closely spaced gamma ray, neutron, density, spontaneous potential, formation microimager and dip meter logs, limited core, and published reports of local outcrops, were used to define three scales of vertical stratigraphic variation within this 1.5 km2 field: (1) decimeters to meters thick log facies; (2) meters to tens of meters thick log successions; and (3) tens to hundred meter thick intervals that are continuous laterally across the field. These variations record changes in sediment supply and depositional energy during progradation and abandonment events varying in scale from local shifts in distributary channels to regional changes in sediment transport along the basin. Well log correlations suggest the Basal Unit comprises a turbidite fan system (250 m thick) trending north to northeast, composed of six, vertically-stacked, distributary channel complexes. Three architectural elements are identified within each distributary channel complex: (1) Major amalgamated channels (30-40 m thick, 150-200 m wide and at least 900 m long) pass down depositional dip into proximal second-order channels that bifurcate basinward (15-20 m thick, symmetric successions); (2) Lobe deposits (20-50 m thick, 400 m wide, and at least 400 m long) are composed of upward-coarsening successions that contain distal second-order channels (1-10 m thick); and (3) Laterally extensive overbank deposits (5-10 m thick), which vertically separate distributary channel-lobe complexes. Reservoir heterogeneities within the Basal Unit are defined by the lateral extent and facies variations across a hierarchy of strata within channel-lobe complexes. Although laterally extensive muddy overbank deposits generally inhibit vertical communication between stacked channel-lobe complexes, in places where high-energy first-order channel sandstones incise underlying muddy overbank deposits, sandstones in subsequent intervals are partially connected. The Basal Unit is bounded on the southwest by a northwest-southeast trending fault that rises 30 degrees towards the northwest to define a structural trap on the northeast side of the field.

A Methodology for Estimating Construction Unit Bid PricesErbatur, Osman 1978- 14 March 2013 (has links)
The internship company does not have a standard procedure for preparing an engineer’s estimate of probable construction cost document (engineer’s estimate) for municipal projects. Every project manager employs a methodology that is a slightly different variation of the historical data approach. The internship objective was to develop a construction unit price estimation model that provides more accurate results than the company’s existing unit price estimation methodology for the City of Fort Worth construction projects.
To accomplish the internship objective several tasks were conducted, including; gathering City of Fort Worth construction projects bid tabulation data (including all bids) for the past three years; developing three construction item unit price databases using the data collected; conducting statistical analyses using the unit price databases;developing tables and graphs showing the construction cost items and their appropriate estimated unit prices to be used by the project managers in their cost estimates; developing an approach to apply construction unit costs which adjusts for unique project characteristics; developing guidelines for using the developed tables and graphs to estimate unit prices for municipal projects; using one recent project to compare the company’s existing unit price estimation methodology and the new developed model with actual unit bid prices; and developing guidelines for updating the unit price database, tables, and graphs.
The study made use of both normal and log-normal distributions to model the unit bid price data collected from the City of Fort Worth. The factors that are perceived to influence a contractor’s unit bid price for a given item were identified and given a degree of impact on the project by the project managers. The factor that had the highest impact on the unit bid prices was discovered to be item quantity. The unit price estimating methodology presented in this study generated a better fit than the internship company’s original method for predicting the actual average unit bid prices for the one case study the methodology was applied.

An Alternative Approach To Regional Economic Income: A Fuzzy Logic Model of BEA Economic AreasCato, Jamel H. 30 August 2005 (has links)
This thesis examines the policy problem of economic unit definition from the perspective of the regional economist. The regional economist faces the challenge of disaggregating macroeconomic activity into subparts that accurately reflect the actual economic organization of a country or region. Such an exercise is important because the Governments of many developed countries rely on it to allocate scarce public resources.
In the United States, the Bureau of Economic Analysis of the U.S. Department of Commerce is responsible for regional economic unit definition. To meet its mandate, the BEA has developed a complex assignment system based principally on commuting flows between regions of the Country. This assignment system works well for the centralized population centers that characterize the majority of the U.S. economy. However, the BEA system is less effective at reflecting the economic organization of rural areas, where there is little interregional commuting. To address this problem, the BEA has developed a practice of using newspaper circulation data as a proxy for economic organization.
In this thesis I develop a partial set model of regional economic organization based on the mathematics of fuzzy logic and propose it as a superior alternative to the BEAs method.

Optimization of VAV AHU Terminal Box Minimum AirflowWang, Wei 2011 August 1900 (has links)
Determining the optimal terminal box airflow is a complex process which is influenced by various factors, such as weather condition, supply air temperature, primary air fraction and internal load. A guideline for determination of a cost efficient minimum airflow setpoint for VAV terminal box units is drawn in this research. The most efficient optimal minimum airflow setpoint should not be a fix setting, but should be changing with zone load and ventilation requirement.
A fixed minimum airflow is used in conventional control strategies. The terminal box minimum airflow required is not a constant since the supply air temperature, fresh air fraction and zone load are different. It is important to set up the minimum airflow to ensure IAQ and thermal comfort and to minimize energy consumption.
Analysis has been carried out to compare how the supply air temperature, fresh air fraction and zone load affect the minimum airflow setting of an exterior zone. And 30% of design airflow is not always a good number, and may cause comfort issue or ventilation problem. If the minimum airflow is set higher than required, terminal boxes will have significantly simultaneous heating and cooling, and consume more fan power in the AHUs. If the minimum airflow is set lower than required, indoor air quality (IAQ) will be a concern. Energy saving ratio study is conducted to estimate the energy saving benefit by implementing an optimized minimum airflow.
