In this paper, we propose a design and implementation of Home Network Middleware which offer integrated service of electronic products. Most senior nations setting to core paradigm to ubiquitous computing techniques and effort to get the novel information and making more power about information techniques. But, they don't have a skill to Home Network Middleware in electronic products. It is a more important in Home Network Middleware. So, we will try to study about Home Network Middleware skill. And suggest to proposition that is a novel Home Network Middleware.

For a more efficient and economical management of substations of power system areas, the concept of substation automation has been introduced using intelligent and ubiquitous IT techniques. In this paper, ubiquitous IT prototype hardware, functions and communication interfaces on an embedded platform for substation automation are proposed. Also, operating system architecture is suggested for the effective implementation of substation automation.

So far, many researches have been conducted in the area of audio based context recognition. Nevertheless, most of them are based on existing feature extraction techniques derived from linear signal processing such as Fourier transform, wavelet transform, linear prediction... Meanwhile, environmental audio signal may potentially contains non-linear dynamic properties. Therefore, it is a big potential to utilize non-linear dynamic signal processing techniques in audio based context recognition.

Ubiquitous computing environment accelerates the advent of the IT Ecosystem. In the coming generation, a massive number of ubiquitous devices and services are converged into an ultra-large-scale system. In this context, high degrees of complexity and organization change the paradigm of knowledge and its management levels. The objective of this paper is to explore the Knowledge Management Systems in view of demands in ultra-large-scale systems. We introduce motivation for Next-Generation (NG) usage and their upcoming requirements. The possible applications will be discussed, and summary of different techniques are conducted. The tools and techniques that allow KMS to operate as "Vital Success Enabler" to achieve organizational benefits will be examined. Potential future directions for research are highlighted: these include advances in knowledge capture, storage / retrieval and sharing techniques, in particular with the surrounding role of information technology.

Users are able to use the information and service more free than previous wire network due to development of wireless network and device. For this reason, various studies on ubiquitous networks have been conducted. Various contexts brought in this ubiquitous environment, have recognized user's action through sensors. This results in the provision of better services. Because services exist in various places in ubiquitous networks, the application has the time of services searching. In addition, user's context is very dynamic, so a method needs to be found to recommend services to user by context. Therefore, techniques for reducing the time of service and increasing accuracy of recommendation are being studied. But it is difficult to quickly and appropriately provide large numbers of services, because only basic context information is stored. For this reason, we suggest DUPS(Dimension User Profile System), which stores location, time, and frequency information of often used services. Because previous technique used to simple information for recommending service without predicting services which is going to use on future, we can provide better service, and improve accuracy over previous techniques.

This paper is about wine quality classification with multilayer perceptron using the deep neural network. Wine complexity is an issue when predicting the quality. And the deep neural network is considered when using complex dataset. Wine Producers always aim high to get the highest possible quality. They are working on how to achieve the best results with minimum cost and efforts. Deep learning is the possible solution for them. It can help them to understand the pattern and predictions. Although there have been past researchers, which shows how artificial neural network or data mining can be used with different techniques, in this paper, rather not focusing on various techniques, we evaluate how a deep learning model predicts for the quality using two different activation functions. It will help wine producers to decide, how to lead their business with deep learning. Prediction performance could change tremendously with different models and techniques used. There are many factors, which, impact the quality of the wine. Therefore, it is a good idea to use best features for prediction. However, it could also be a good idea to test this dataset without separating these features. It means we use all features so that the system can consider all the feature. In the experiment, due to the limited data set and limited features provided, it was not possible for a system to choose the effective features.

Exiting systems are essential to prevent casualties in case of fire. However, existing guidance systems are lack of flexibility because their functionalities are fixed when they are planned. In this paper, a system is introduced which guides evacuees in realtime by processing data it gathers throughout various sensors in realtime. It is planned and designed to aid quick and efficient evacuation, and produced, installed and tested in an underground space to show its feasibility. In building the system, ubiquitous techniques are employed for its sensor network and evacuee positioning in an attempt to make it cheap and extendable.

Nowdays, in order to reduce recent traffic accident the traffic accident research which uses IT techniques is plentifully advanced. But, when running away traffic accident occurs, the assault vehicle the searching is difficult very from site. Respected a traffic accident investigation scientification RFID techniques and type expense to use an ubiquitous theory constructs the traffic accident preventive system which is efficient the algorithm which proposed. Especially in this paper, It simulated that every hour changes road follows produces the optimum traffic safety speed which in situation and weather condition.

Future space is currently getting a great deal of attention to apply ubiquitous computing technology. At the same time, various ubiquitous technology-based products are being developed with service scenarios in the views of diverse user groups predicted. Since these service models and scenarios need to be tested to verify effectiveness, it requires researchers to predict spatial shapes and service scenarios for future domestic environment that fulfills diverse future spatial requirements including ecological and user-oriented spaces, extended amenity getting maximum benefits from technology, etc. To support these developments, the need to make a physical test-bed, a real building model, is essential. However building a physical test-bed generally is economically expensive and even if the test-bed could be settled, it must be carefully designed before it is built In this paper, we suggest a virtual smart test-bed, called "V-PlaceLab", using virtual reality techniques. This system allows not only to inspect a scenario with the aid of computer simulation on a virtual environment, but also to design a virtual test-bed mentioned above.
