Building Information Modeling (BIM) är ett arbetssätt och samlat begrepp som ger möjlighet att visualisera önskad design i verklig storlek och dimensioner (ur olika vinklar och vyer). BIM är en smart teknik och en ny designprocess där all information och konstruktion specifikationer skapas i en digital fil. Så BIM är inte enbart en mjukvara, utan en enorm teknik. För att implementera denna teknik Building Information Modeling (BIM) is a way of working and collective concept that provides the opportunity to visualize the desired design in real size and dimensions (from different angles and views). BIM is a smart technology and a new design process where all information and construction specifications are created in a digital file. So BIM is not just a software, but a huge technology. To imp

The construction sector is often criticized for its lack of efficiency and quality.When the construction industry is compared to the rest of the domestic manufacturing industry, the general conclusions of the industry’s low efficiency is confirmed. The purpose has been to clarify why there is no sustainable building, despite the well-developed technology that now is available. The report also exam

Scania is a region in southern Sweden that used to be a region of wetlands. Nevertheless, due to human activities wetland loss is an established matter currently, and following from that, changes in biodiversity, water regime and nutrient retention. One purpose of creating new wetlands is to reinstate good status of biodiversity. The study was based on data gathered in July 2011 from 13 newly con

The purpose of this study is to investigate what determines an individual to join the firm and how the membership in the firm affects the individual and his identity. This study is based on the interviews with six members of a football firm in Sweden. The selection of firm members to participate in this study was made based on the writers contacts within the firm. The results of this study shows t

A lot of people suffer from nocturia which means that they have to get up in the mid-dle of the night to urinate. For the everyday healthy human this is not a serious prob-lem, they manage to go to the bathroom by themselves. But to the elderly population there is a risk involved. They could get hurt on the way to the bathroom or in many cases simply not wake up and urinate in their sleep. The exi

This report is written during a Master Thesis carried out at Volvo Aero Corporation, VAC, in relation with the Division of Production and Materials Engineering at Lund Institute of Technology. The purpose with this report is to get a better insight in some of the problems occurring during the manufacturing of a space nozzle. At VAC a new kind of nozzle wall design has been introduced for their sp

A year after the establishment of the protest camp Palestinagård at Lund’s University in May 2024 and its demolishment by the authorities, the student solidarity movement is continuously engaged in endeavours to get into conversations with the institutions at Lunds University to make their demands heard, as the genocide on the Palestinian population in Gaza is still ongoing. Further, Palestinagård

Disinformation is growing rapidly on social media, driven by evolving tactics. Meanwhile, the shift towards community-based fact-checking has raised concerns among fact-checking organizations. This study aims to explore fact-checkers’ perceptions of changes in social media governance models to counter disinformation. Based on qualitative interviews with European fact-checkers, the study reveals th

This work presents a statistical approach for estimating and analyzing the downward transport pattern and distribution of soil water by the use of pattern analysis of space-time correlation structures. This approach, called the Space-time Correlation Field, is mainly based on the analyses of correlation functions simultaneously in the space and time domain. The overall purpose of this work is to d

In modern chemical process industry, process state transitions, or grade changes, are common operations. Frequent production changes increase the focus on efficient operator support for such procedures. The aims of a grade change may be complex, and sometimes conflicting.Fast transitions are desirable in order to minimize production loss. There may also be safety aspects that must be considered, i

Is the real problem in resolving correspondence using current stereo algorithms the lack of the "right" matching criterion? In studying the related task of reconstructing three-dimensional space curves from their projections in multiple views, we suggest that the problem is more basic: matching and reconstruction are coupled, and so reconstruction algorithms should exploit ths rather than assuming

The non-associated plasticity model is utilized to simulate a three dimensional nonlinear finite element analysis on sand. The model is a three-dimensional generalization of the Cam-Clay model with yield- and flow potential functions expressed in a common format, but with different shapes and hardening rule depending on both the shear and volumetric stains, which enables modelling of dilation. The

Monolithic neural networks may be trained from measured data to establish knowledge about the process. Unfortunately, this knowledge is not guaranteed to be found and – if at all – hard to extract. Modular neural networks are better suited for this purpose. Domain-ordered by topology, rule extraction is performed module by module. This has all the benefits of a divide-and-conquer method and opens

Performance modeling is an important topic in capacity planning and overload control for web servers. We present a queueing model of an Apache web server that uses bursty arrival traffic. The arrivals of HTTP requests is assumed to be a Markov Modulated Poisson Process and the service discipline of the server is processor sharing. The total number of requests that can be processed at one time is l

We have recently considered the problem of tuning a static plant described by a differentiable input-output function, which is completely unknown, but whose Jacobian takes values in a known polytope of matrices: to drive the output to a given desired value, we have suggested an integral feedback scheme, whose convergence is ensured if the polytope of matrices is robustly full row rank. The suggest
