In the following study the properties of the superabsorbent polymer Broadleaf P4 were investigated according to the aim to apply that polymer within constructed wetlands. The application of the polymer in constructed wetlands shall result in an improvement of the removal of pesticides. For that the polymer was given into lab-scale wetlands together with pumice and were compared to a control wetland, which was filled with gravel. The wetlands were running for several weeks in which the nutrient removal was recorded. The polymer was also tested according to its property to adsorb the pesticides before adding the pesticides to the wetland beds.
FUSO is one of the Japanese leading manufacturing of trucks and buses in the world and also it is an integral part of Daimler AG. Being a large manufacturer in trucks and buses, Fuso faces some marketing issues due to corrosion issues. Corrosion is one of the major issue to breakdown or damage the performance of the vehicles. To encounter this issue, FUSO initiated new project and called as “Anti-Corrosion Project”. The main mission of this project is to improve the corrosion resistivity or performance of the metal parts. Currently FUSO has almost 70 percent of parts which lies under Grade-III i.e. lesser than the one year corrosion resistivity.
In this project, the corrosion issues are collected by different types of audits like from customer as well as from taking two years old vehicle in worst conditions. Listed corrosion issues further investigated for current specification and requested for new proposal from supplier. Then the proposed solution is internally estimate the cost and make negotiation with the supplier. Later it’s forwarded to meeting with top management for approval. In case of higher corrosion specification, parts are taken from production line and tested in material lab which is available in FUSO. At last, the approved proposal is requested to release the drawing change and further the new proposal will be implemented. Entire project it should be coordinate with all different departments and working with teams gives more deep knowledge about the cause of issues.
With this project, parallel focused on the shop floor developments in return parts management area. FUSO is also responsible for the after sale services. In other words, FUSO provides warranty for the parts which breakdown within three years. Breakdown parts are directly delivered by the customers through dealers for warranty claim, so these parts called Warranty Part Investigation (WPI) parts. Sometimes customer wants to know the cause of the breakdown even though warranty has expired, in this case company will investigate the cause but they don’t provide the warranty. These kind of parts known as Product Quality Report (PQR) parts.
Company has a different shop floor for return parts and these parts are directly received by the company. RPM has four processes i.e. inwarding, pre-analysis, investigation and dispatch or scrap.
Usually, company used to get 30-50 parts per day, recently they decided to receive all the breakdown parts. Hence, it results in increasing the delay of inwarding and other processes. To solve this, standard layout and process are constructed. And, one of the main reasons for inward delay is higher documentation which is basically not required. These are converted into automation or digitalize work. Improvements are done using the lean manufacturing project methodology which results in more inward of failure parts and less inventory.
Many companies use machine learning techniques to support decision-making and automate business processes by learning from the data that they have. In this thesis we investigate the theory behind the most widely used in practice machine learning algorithms for solving classification and regression problems.
In particular, the following algorithms were chosen for the classification problem: Logistic Regression, Decision Trees, Random Forest, Support Vector Machine (SVM), Learning Vector Quantization (LVQ). As for the regression problem, Decision Trees, Random Forest and Gradient Boosted Tree were used. We then apply those algorithms to real company data and compare their performances and results.
The application described in this thesis has been created, built and designed to help nurses or any medical personnel all around the world in being able to access a real-time database to store patient records like Patient Name, Patient ID, Patient Age and Date of Birth, and the Symptoms that the patient is experiencing. A real-time database is a live database where all changes made to it are reflected across all devices accessing it. This application will be beneficial especially in countries where access to a computer or medical equipment is not always possible. A phone is always ready use and at the reach of the hand, users of this application will always be able to access the data at any given time and place. We will be able to add a new patient or search for existing patients. In addition, this application allows us to take RAW medical images that can be used to identify anomalies in the blood sample. RAW images are important for this application because they’re uncompressed, which means, they do not lose any quality or details. The users of this application are the medical personnel that will be taking care of the patients. These users will have to create a profile on the database in order to use the application, since their data, like user ID, will be used in order to control the behaviour of the data retrieved and stored. We will also discuss the current and future features of this application, as well as, the benefits of this application when it comes to the medical personnel, as well as patients. Finally, we will also go
over the implementation of such application from a hardware perspective, as well as a software one.
Implementation of a customised business model for innovative engineering consultancy services
(2019)
Business development is vital for every organisation who intend to grow. It follows expansion through organic and inorganic means. Also, there are many innovative business styles which help organisations to expand. This thesis shows how engineering services organisation chose its form of business expansion
The following thesis explains how engineering service sector company uses its expertise to expand its business towards consultancy market with the demonstration of the real-life executed business model.
The thesis provides a solution for the following issues
1) What is the best in-house strategy to be developed for business expansion in the service industry?
2) How did the niche market experiences help for business expansion?
Social media platforms play an increasing role in marketing, politics and police affairs, because they can strongly influence opinions. So called “opinion leaders” exert their influence in a given network and shape the opinions of other users. Identifying central nodes in a social graph has been of interest for decades. However, not all centrality measures were developed for social media platforms. They were built for social graphs, which did not include additional metrics (e.g. “likes”, “shares”). Nevertheless, these metrics play a crucial role on modern platforms. Hence, outdated measures need to be adjusted and additional metrics need to be integrated to ensure the best possible results.
Prototype-based classification methods like Generalized Matrix Learning Vector Quantization (GMLVQ) are simple and easy to implement. An appropriate choice of the activation function plays an important role in the performance of (deep) multilayer perceptrons (MLP) that rely on a non-linearity for classification and regression learning. In this thesis, successful candidates of non-linear activation functions are investigated which are known for MLPs for application in GMLVQ to realize a non-linear mapping. The influence of the non-linear activation functions on the performance of the model with respect to accuracy, convergence rate are analyzed and experimental results are documented.
This master thesis covers the topics of Customer relationships formation in the IT-outsourcing market on the example of “ABC” company. Most works related to the topic IT outsourcing cover the problems of implementation of IT services and the process of providing them to the customers and mostly all the issues are covered from the perspec-tive of consumers. Thus, problems and results of outsourcing providers of IT services remain almost uncovered. This master thesis is to reveal the specific features of IT out-sourcing business in Belarus and to develop an approach to the formation and construc-tion of a system of relationships between the company and its clients as a source of competitiveness increase.
