GSM Based SMS Driven Automatic Display Toolkit for College Noticeboard (Electronics Project)

The main aim of the project will be to design a SMS driven automatic display toolkit which can replace the currently used programmable electronic display. It is proposed to design receive cum display toolkit which can be programmed from an authorized mobile phone.

The message to be displayed is sent through a SMS from an authorized transmitter. The toolkit receives the SMS, validates the sending Mobile Identification Number (MIN) and displays the desired information after necessary code conversion.

The system is made efficient by using ‘clone’ SIMs of same MIN in a geographical area so that the same SMS can be received by number of display boards in a locality using techniques of time division multiple access. Started of as an instantaneous News display unit, we have improved upon it and tried to take advantage of the computing capabilities of microcontroller. We envision a toolkit that will not only display message but also can be used to do some mechanical work.

Looking into current trend of information transfer in the campus, it is seen that important notice take time to be displayed in the notice boards. This latency is not expected in most of the cases and must be avoided.

It is proposed to implement this project at the institute level. It is proposed to place display boards in major access points. The electronics displays which are currently used are programmable displays which need to be reprogrammed each time. This makes it inefficient for immediate information transfer, and thus the display board looses its importance. The GSM based display toolkit can be used as a add-on to these display boards and make it truly wireless. The display board programs itself with the help of the incoming SMS with proper validation. Such a system proves to be helpful for immediate information transfer.

The system required for the purpose is nothing but a Microcontroller based SMS box. The main components of the toolkit include microcontroller, GSM modem. These components are integrated with the display board and thus incorporate the wireless features. The GSM modem receives the SMS. The AT commands are serially transferred to the modem through MAX232. In return the modem transmits the stored message through the COM port. The microcontroller validates the SMS and then displays the message in the LCD display board. Various time division multiplexing techniques have been suggested to make the display boards functionally efficient. The microcontroller used in this case is Philips P89C51RD2BN. Matrix Simado GDT11 is used as the GSM modem. In the prototype model, LCD display is used for simulation purpose. While implementation this can be replaced by actually display boards.

The results presented in the thesis support the proper functionalities and working of the system. The timing diagram suggests the response of the modem to various AT commands.

Remote Controlling of Home Appliances using Mobile Telephony (Electronics Project)

In modern days, we must use various high-tech machineries and equipments to get our jobs done and make the life easier. These machineries should be controlled by the homeowner from any location as the homeowner might be away from home at workplace or traveling in a different place in the weekend. Thus a system of remote monitoring and controlling are very much necessary.

Smart home is one of these types of system equipped with home appliances which we wish to control smartly from anywhere. Some products are commercially available which allow remote home appliance controlling through internet which is undoubtedly emerging. But it lacks the true sense of real mobility and security, making the remote home appliance controlling a limited term than it is supposed to be.

In search of a true remote and adequately secure solution to be really effective and practicable, mobile telephony is better than any other solutions. Mobile phones have become almost an inseparable part of civil lives today. In this paper we introduce a new mechanism so that the ordinary services of the mobile phones can be leveraged to communicate with and control the home appliances and make our homes a really smart one.

Green Supply Chain Management in Thailand: An Investigation of the Use in the Electrical and Electronics Industry (Management Project)

The objective with this project is to clarify the advantages – both economic and environmental – that companies in the Thai electronic manufacturing industry can draw from managing their supply chain and adding a green aspect to it. This through investigations of the concept known as Green Supply Chain Management (GSCM). The research will assist companies with scarce knowledge of green supply chain management in making decisions and priorities in that area.

Semi-structured interviews were performed on sight in Bangkok, Thailand and surrounding region. These provided insight and knowledge of the situation and today-state regarding environmental awareness and GSCM implementation within the Thai Electrical and Electronics Industries. Interviews were performed with representatives and experts from different sectors – from universities, industry and supporting agencies and serve as the foundation for the research.

A model has been developed out of previous research and findings that could suit the Thai industry. This model can be seen as guidelines in the work towards becoming green and aims at continuous improvement of the organizations environmental performance.

In Thailand today companies do not see the benefits of themselves review their organizations environmental impact or developing in this area. Environmental awareness among the public is low and the lack of demand for green products result in few drivers for companies to become green. Also the lack of proper legislation and compliance audits are part of the problem. Missing environmental education and knowledge are extensive and improvements needed. The concept of GSCM is not wide spread but popularity is increasing steadily. Some environmental initiatives are though performed in the industry but not under the name of the concept. Customer demands, legislation and education should be the main focus areas for developing the industry.

From the today state at a very basic low much is to be done. Fear of large investments, cost and the lack of knowledge are obstacles to the development. This research shows that these concerns are to be avoided. And by following the model in this thesis companies can find proper knowledge in the area of GSCM. Concluded is that with understanding of the concept and proper implementation from the right knowledge Thai companies can gain great advantages in the future – both economical and environmental.

Interim Management (Management Project)

The economic context changes, companies adapt and recruitment evolves. As future managers and leaders, or simply new actors in the working environment, this is our duty to be aware of the demand of the market.

The economic situation has a huge impact on the recruitment and this more so in a crisis period (Aswegen, 2009). In order to respond of the need of flexibility, facing crisis situation or simply facing the need of change, Interim Management seems to correspond to this request or is at least one of the tools that companies can take into consideration.

During the previous phase of our thesis, we realized that only a few people were aware of this promising concept of management. It became a challenge for us, we wanted to know more about this topic and to write a paper in order to share the knowledge that we would gather through the process of depicting this emerging phenomenon called, Interim Management‟ while remaining objective.

During our research and interviews, we met recruitment consultants, Interim Managers, and corporate human resources directors; all of these meetings helped us to understand companies’ needs and what they expect when hiring Interim Managers. Our thesis aims at explaining and depicting the emerging concept of Interim Management in order to give our vision of the reality.
