The trend in the design of complex instruments is toward distributed control systems implemented with networks of embedded devices. Historically these embedded networks have been implemented using field busses such as CAN, LonWorks, or ProfiNet but the ubiquitous nature and low cost of Ethernet has made it the trend in embedded network applications. Ethernet, however, largely depends on DHCP and DNS servers or static IP addressing scheme to enable communication between devices on the network. This paper presents a service-oriented architecture for self-configuring Ethernet-based distributed control systems that is able to adapt to changes in network topology without manual intervention. The three core technologies used to enable self-configuration are all part of Zero Configuration Networking: link-local address auto-configuration for automatic IP address assignment, multicast DNS for automatic hostname resolution, and multicast DNS service discovery for automatic discovery of services. A temperature control system is developed as a case study implementation of the architecture using java and SOAP web services. Programming web services is simplified using the java API for XML-Web Services. Programmer productivity is also improved since java enables the use of enterprise level development tools for debugging and deployment.

In our previous research we have presented a framework for the development and deployment of web-based applications. This paper elaborates on the core components (functional and data) that implement the generic, reusable functionality. Code segments of the components are presented, along with a short sample application. In addition, we introduce some changes that are mainly driven by usability and performance improvements, and are in adherence with the principal rules of the framework's operation. Those changes enable us to extend the applicability of the framework to other families of applications, apart from web-based business applications.

Tato práce se zabývá monitorováním vybraných činností na přenosných mobilních zařízeních s operačním systémem Android a následným zpracováním dat pomocí webové aplikace. Těmito činnostmi jsou myšleny telefonní hovory, textové zprávy a lokace. Představuje existující aplikace, které k monitorování slouží. Dále obsahuje analýzu možností monitorování vybraných činností na uvedených zařízeních. Zahrnuje také specifikaci, návrh, implementaci, předvedení a testování nového systému určeného k monitorování činností a zpracování dat.

The ultimate goal of research on Speech to Text system is to build machines that are indistinguishable from humans in the ability to communicate in natural spoken language. This paper discusses the implementation of a connected word Speech to Textsystem (STT) for the Punjabi language. Hidden Markov model toolkit (HTK)has been used to develop the system. A java platform based Graphical User Interface (GUI) has been developed to make the system fast and user friendly. The implemented system performs well with Word Recognition Rate (WR) 95.8% and 95.4%, Word Accuracy Rate (WA) 94.1% and 91.6% and Word Error Rate (WER) 5.9% and 8.35% in class room and open environment respectively.

Health tourism is now popular and being promoted in Thailand since it is one of the growing industry. Health tourism information is scattered around in many places especially, in the websites. A health tourism service provider may be in many forms such as in the hotel, as a separated business, as a hospital etc. Each service provider may have its own website as well as the websites from common providers such as Tripadvisor, Agoda, or Atsiam, etc. Each website provides different information about just one service provider. In this work, we are interested in information gathering process for health tourism. We introduce the use of parallel java platform to gather the tourism information particularly, using a java concurrent program and merge the information using MapReduce. The information we gather are preprocessed and combined with the information manually collected. Google Refine is used to merge all the information into single health tourism ontology.
