13 104 - PublicationRobust Method to Identify Vehicleson Thermal Images at Night(Chulalongkorn University Printing House, 2013)
; The research presents a robust method to categorize nighttime traffic by thermal images. The objective of the research is to identify and separate vehicles from unimportant thermal objects of nighttime traffic. Various thermal features of a vehicle comprising windscreen, engine heat and elsewhere, are depicted as different intensities in each thermal image. Moreover, the relation between the three features can be illustrated as a semi-Gaussian statistical distribution of data, which differentiates one type of vehicle from another. To recognize a vehicle type, there are three operating modules proposed in this research, comprising vehicle-thermal features detection, semi-Gaussian evaluation and decision, respectively. Initially, the detecting process finds a vehicle engine heat-feature by subtracting the road's intensity, selecting a suspected area to cover the vehicle's windscreen feature. Secondly, semi-Gaussian thermal distribution model is implemented to evaluate similarity between the suspected area and the model. Eventually, the decision is made based on the similarity to confirm whether it is a vehicular type or not. Experimentally, using four types of vehicles consisting of a car, van, truck and thermal object, the accuracy of identifying is extremely high.3 29 - PublicationThe GS1 Global Traceability Standard forthe Food Industry: A Case Study ofThai Beef Industry(Chulalongkorn University Printing House, 2011)
; Nowadays, traceability is recognized as an important task of food industry to givecustomers confidence in the products they buy for home consumption. Furthermore,in terms of food safety, exporting food products to the EU and developed countriessuch as Japan, Australia and U.S.A., all have specific requirements. In addition,Thailand’s General Food Law came into force in 2009, just like the EU’s, and makestraceability compulsory for all food and feed businesses. It requires that all food andfeed operators implement special traceability systems. They must be able to identifywhere their products have come from and where they are going to, and to rapidlyprovide this information to competent authorities in case a problem is found with theirproducts. The purpose of this article is to propose the concept and process of theGS1 Global traceability Standard for the food industry through a case study in theThai beef industry. This study will allow the readers to understand and realize thebasic steps to establish a traceability system for their business following the GS1global traceability standard.16 68 - PublicationThe Optimum Solutions for the Power LossesReduction in the Distribution Systems(Chulalongkorn University Printing House, 2009)
; This paper describes the mathematical procedure for the generalized equations onthe power losses reduction with the shunt capacitor on the feeder circuit in anydistribution systems which have different representative reactive load patterns,e.g. uniformly distributed reactive loads, concentrated reactive loads, or a combinationof uniformly distributed and concentrated reactive loads. The generalized equations arederived to receive the optimum shunt capacitor location, size and power lossesreduction for each of the representative reactive load patterns by using computer aidanalysis.2 18 - PublicationThe Survey of Problems and Solutions for ERP Implementation in Thai Industry(Chulalongkorn University Printing House, 2014)
; ; ; In today's global free-trade environment, most industries have to increase their potential in order to increase their competitiveness. It is known that successful implementations of the Enterprise Resource Planning system or ERP system in an organization can enable company personnel resources to improve their efficiency and effectiveness. However, not all organizations have achieved or been successful with ERP implementation. Also, it possibly generates new problems in the organization. The objective of this research is to investigate the problems and causes of unsuccessful ERP implementation in order that the obtained results can be used as guidelines for organizations that are requiring the ERP system. The research was initially conducted by in-depth interviews of the top management of research focused industries comprising 25 companies in order to study the companies' background and their business process. This was followed by management training and workshops on the business process writing and process improvement with the company project teams. Finally, following a discussion with top management and project teams, the organization can generate the to-be or expected business process. The results of the research shows that companies who have not implemented the ERP system are now encountering the following problems: top management do not understand or recognize the benefits of the ERP system, the company business process is not efficient and unable to integrate with the ERP system. Furthermore, the company does not know how to prepare and adjust to the ERP project. Of those organizations who are currently implementing the ERP system, most are encountering problems of inefficiency and not fully utilized ERP system to its potential such as inaccurate data, unreal time data, unreliable data and inconsistency of requirement data, and so on. The above results can then be used as supporting information for organizations on how to prepare themselves before implementing the ERP system and how to solve their ERP related problems.17 31 - PublicationUse of the Internet for Citizens Participation in Air Quality Management in Bangkok(Chulalongkorn University Printing House, 2008)
