(2022)This thesis is a review of articles focusing on software assisted floor plan design for architecture. I group the articles into optimization, case based design, and machine learning, based on their use of prior examples. I then look into each category and further classify articles based on dimensions relevant to their overall approach. Case based design was a popular research field in the 1990s and early 2000s when several large research projects were conducted. However, since then the research has slowed down. Over the past 20 years, optimization methods to solve architectural floor plans have been researched extensively using a number of different algorithms and data models. The most popular approach is to use a stochastic optimization method such as a genetic algorithm or simulated annealing. More recently, a number of articles have investigated the possibility of using machine learning on architectural floor plans. The advent of neural networks and GAN models, in particular, has spurred a great deal of new research. Despite considerable research efforts, assisted floor plan design has not found its way into commercial applications. To aid industry adoption, more work is needed on the integration of computational design tools into the existing design workflows.

(2023)A case study that studied the performance impact of a node.js component when it was refactored from monolith environment into independent service. The performance study studied the response time of the blocking part of JavaScript code in the component. The non blocking part of the code and the added network overhead from the refactoring were excluded from the performance review. Literature review didn’t show any related research that studied the performance impact of a node.js component when it was refactored from monolith into microservices. Many found studies were found that studied the response time and throughput of REST API build with node.js with comparisons to other programming languages. A study were found that related to refactoring an application from monolith into microservices. None of the found studies were directly related to the studied case. It was noted that the response time of the component improved by 46.5% when it was refactored from monolith into microservice. It is possible that when a node.js monolith application grows it starts to affect the throughput of the event loop affecting performance critical components. For the case component it was beneficial to refactor it into independent service in order to gain the 92.6ms in the mean response time.

(2021)Remote sensing satellites produce massive amounts of data of the earth every day. This earth observation data can be used to solve real world problems in many different fields. Finnish space data company Terramonitor has been using satellite data to produce new information for its customers. The Process for producing valuable information includes finding raw data, analysing it and visualizing it according to the client’s needs. This process contains a significant amount of manual work that is done at local workstations. Because satellite data can quickly become very big, it is not efficient to use unscalable processes that require lot of waiting time. This thesis is trying to solve the problem by introducing an architecture for cloud based real-time processing platform that allows satellite image analysis to be done in cloud environment. The architectural model is built using microservice patterns to ensure that the solution is scalable to match the changing demand.

(2023)This thesis examines Japanese castle reconstructions in the Heisei (1989–2019) and Reiwa eras (2019–) and links them to the ideas of cultural heritage and authenticity in traditional architecture. Japanese castles are opportune for examining the development of the role of architecture in cultural heritage throughout history. The role of castles as symbols of authority and later as symbols of local culture and history has changed according to the fluctuations of time and the needs of the contemporary people and thoughts. After majority of the feudal castles were demolished during Japan’s modernization, there have been three distinctive “booms” during which castles have been reconstructed. In the post-war era, dozens of ahistorical concrete replicas of castles were rebuilt concrete as local town symbols, and to many they symbolized the rebuilding of post-war Japan. From the early 1990s, however, a new castle boom has taken place, with the reconstructions emphasizing on using wood and historical evidence. Most notable of these reconstruction projects is the Nagoya Castle reconstruction project, in which the post-war concrete castle tower is to be demolished and rebuilt from wood using original methods and historical plans. This thesis examines these reconstructions in contemporary Japan, aiming to understand how authenticity and cultural heritage are related to this ongoing boom. In this study, a country-wide visitor survey on 10 Japanese castle sites was conducted, supported by two expert interviews from supervisors of two Heisei era castle reconstructions in Ōzu and Kakegawa cities. The findings supported the hypothesis, which suggested that the current appeal of castles is linked not only to their symbolic value to the castle towns, but also their value as objects of cultural heritage. This is why “authentic”, wooden reconstructions are preferred, which was evident from the visitor surveys, as all the respondents favored wooden reconstructions over concrete ones. Furthermore, majority of the respondents wished for more authentic castle reconstructions to be built.
