Front end development for building automation systems using JavaScript Frameworks

Automation technologies are widely acclaimed to have the potential to significantly reduce energy consumption and energy-related costs in buildings. However, despite the abundance of commercially available technologies, automation in domestic environments keep on meeting commercial failures. The main reason for this is the development process that is used to build the automation applications, which tend to focus more on technical aspects rather than on the needs and limitations of the users. An instance of this problem is the complex and poorly designed home automation front-ends that deter customers from investing in a home automation product. On the other hand, developing a usable and interactive interface is a complicated task for developers due to the multidisciplinary challenges that need to be identified and solved. In this context, the current research work investigates the different design problems associated with developing a home automation interface as well as the existing design solutions that are applied to these problems. The Qualitative Data Analysis approach was used for collecting data from research papers and the open coding process was used to cluster the findings. From the analysis of the data collected, requirements for designing the interface were derived. A home energy management functionality for a Web-based home automation front-end was developed as a proof-of-concept and a user evaluation was used to assess the usability of the interface. The results of the evaluation showed that this holistic approach to designing interfaces improved its usability which increases the chances of its commercial success.

Specification of a smart meter/actuator description mechanism & development of a mobile application

Home Automation holds the potential of realizing cost savings for end users while reducing the carbon footprint of domestic energy consumption. Yet, adoption is still very low. High cost of vendor-supplied home automation systems is a major prohibiting factor. Open source systems such as FHEM, Domoticz, OpenHAB etc. are a cheaper alternative and can drive the adoption of home automation. Moreover, they have the advantage of not being limited to a single vendor or communication technology which gives end users flexibility in the choice of devices to include in their installation. However, interaction with devices having diverse communication technologies can be inconvenient for users thus limiting the utility they derive from it. For application developers, creating applications which interact with the several technologies in the home automation systems is not a consistent process. Hence, there is the need for a common description mechanism that makes interaction smooth for end users and which enables application developers to make home automation applications in a consistent and uniform way. This thesis proposes such a description mechanism within the context of an open source home automation system – FHEM, together with a system concept for its application. A mobile application was developed as a proof of concept of the proposed description mechanism and the results of the implementation are reflected upon.

Towards a better energy efficiency through a systems approach in an industrial forklift

The purpose of this study is to improve the potential energy recovery to electric energy in an electrohydraulic forklift system. The initial achieved result for energy saving ratio after structural optimization is 40 %. Component optimization is applied to the tested drive which consists of a DTC controlled electric servo motor directly running a reversible hydraulic pump. According to the study the energy efficiency and the energy recovery from the electro-hydraulic forklift system can be increased by 11 % units. New ideas and directions of further research were obtained during the study.

Development of sales invoicing process in industrial services

The objective of this Master’s thesis is to find ways to streamline the invoicing process of the case company. In order to streamline the process, the bottlenecks and development areas of the present invoicing process needs to be identified. The bottlenecks are based on interviews made to personnel. The thesis also offers solutions to overcome the identified bottlenecks. The problem is the slowness of the invoicing process which should get rid off. The slow invoicing process causes delays in obtaining payments. There are many reasons for the slowness and inefficiency of the invoicing process. One of the biggest reasons is that the information systems are not deployed entirely. It causes additional work for everyone. Practices with the customers affect also to the smooth flow of invoicing. The contracts determine when the customer can be invoiced but also work approvals, missing work orders and customer’s own invoicing basis slow the process. The fastest and cheapest solution is to deploy the systems better and do things correctly. Thus duplicated work would decrease and resources would be saved. The work allocation should be modified and the practices with customer should be influenced too. In the future the meaning of IT should be highlighted and new devices exploited.

Framework for Marketing Automation: Case Vaisala

Työ käsittelee Markkinoinnin Automaatiota, viitekehyksen rakentamista Markkinoinnin Automaation käyttöönottoon ja sen hyödyntämiselle markkinoinnin ja myynnin putken hallinnassa. Työ on suoritettu tapaustutkimuksena, jonka primääri datana on käytetty puoli-strukturoituja haastatteluja ja sekundääri datana on käytetty dataa myynnin tietojärjestelmistä. Kirjallisuuskatsaus markkinoinnin automaatioon paljastaa, että aihetta ei ole juurikaan tutkittu akateemisesti. Etenkin selkeitä aukkoja teorioissa on miten markkinoinnin automaatiota kannattaisi aloittaa ja miten siihen tarvittavia kamppanjoita kannattaisi rakentaa. Tapaustutkimuksen tuloksena selvisi selkeät ongelma kohdat nykysessä markkinoinnin ja myynnin putkessa, ja myös kohdat joissa markkinoinnin automaatio voi olla avuksi. Suurin osa ongelma kohdista on markkinoinnin ja myynnin välissä. Toimiakseen markkinoinnin automaatio vaatii selkeät määritykset yrityksessä Liidille ja miten sitä käsitellään. Toimivuuden takaamiseksi se tarvitsee myös jatkuvaa palautetta liideistä ja myynneistä. Alue mikä myös tarvitsee muutosta paremman toimivuuden takaamiseksi on markkinoinnin kamppanjoiden suunnittelu, yhdessä myynnin kanssa ja asiakkaan polku edellä. Tulevaisuuden tavoitteena tulisi olla viestien personointi ja asiakkaiden profilointi. Tulevaisuuden tutkimuskohteet olisivat erittäin avuliaita yrityksille, varsinki jos ne käsittelisivät käyttöönottoa tai personointia.
