The paper deals with dynamic energy management for smart-grid powered coordinated multi-point (CoMP) transmissions. Aiming to minimize the expected energy transaction cost while guaranteeing the worst-case users' quality of service (QoS), an infinite-horizon optimization problem is formulated to obtain the optimal downlink transmit beamformers that are robust to channel uncertainties. Capitalizing on the virtual-queue based relaxation technique and the stochastic dual-subgradient method, an efficient online algorithm is developed in this context. Without a-priori knowledge of any statistics of the underlying random processes, it is rigorously established that the proposed algorithm is able to yield a feasible and asymptotically optimal solution.

This paper presents a design of an elliptical patch textile antenna having operating frequency at 2.45 GHz for RFID application. The proposed antenna consists of elliptical patch on Dacron fabric (□ r =3) as substrate followed by a partial ground at the back of the substrate. The overall size of the proposed antenna is 45×38 mm 2 . The proposed antenna has a gain of 3.386 dB with VSWR of 1.07. The performance of the proposed antenna is analyzed under four angles of bending. The effect of change in feed length is also focused. The characteristics, low profile and compact size of the antenna depicts as a potential candidate for RFID application. CST Microwave Studio package is used for design and simulation purpose.

Although many methods have been suggested to automatically recover traceability links in software development, they do not cover all link combinations (e.g., links between the source code and test cases) because specific documents or artifact features (e.g., log documents and structures of source code) are used. In this paper, we propose a method called the Connecting Links Method (CLM) to recover transitive traceability links between two artifacts using a third artifact. Because CLM uses a different artifact as a document, it can be applied to kinds of various data. Basically, CLM recovers traceability links using the Vector Space Model (VSM) in Information Retrieval (IR) methods. For example, by connecting links between A and B and between B and C, CLM retrieves the link between A and C transitively. In this way, CLM can recover transitive traceability links when a suggested method cannot. Here we demonstrate that CLM can effectively recover links that VSM is hard using Open Source Software.

This paper discusses the learning through body babbling, which is the initial stage of development and learning of human, from the view point of constructive approach for the recognition and behavior architectures of human. In previous researches, the body babbling and learning in the developmental process of drawing manipulation is modeled with two processes, a random joint angle generation process and an offline learning process with neural network. However, there is much gap between these models and the development of human. Human's developmental process is featured by the two processes, a judgment process for exploratory behaviors and an online incremental learning process. In this research, we propose a babbling-and-learning model that includes a judgment process for planned exploratory behaviors and an online incremental learning process. The online incremental learning process is modeled by Continuous System (Dynamics) Learning Tree (CSLT, DLT). CSLT realizes similar learning with neural network with an additional feature, online incremental learning. The proposed model introduces ε-greedy method for this judgment. After joint angles are executed, CSLT learns the obtained data by its online incremental learning process. As results of the validation of the proposed model, the proposed model gathered more number of effective data. The learning model decreased its prediction error faster than the previous model.

Hybrid renewable energy systems shows a great potential for electricity generation in Bangladesh. Hybrid renewable energy system can be set up such a way that the electricity will add to national grid connection and it will eventually reduce the pressure of electricity demand from national grid. Abundance of renewable energy sources in the form of solar energy provides opportunities of renewable energy based hybrid energy system in the industrial areas of Bangladesh. This work is an in-dept. scenario and analysis of the renewable hybrid energy system in Tongi industrial areas of Bangladesh. This study is also includes co-production of diesel generator, solar PV and grid system. Optimization of hybrid renewable energy systems looks into the process of selecting the best components and its sizing with appropriate operation strategy to provide cheap, efficient, reliable and cost effective alternative energy. This paper analyzes all the conditions and constraints of the renewable energy integrated grid connection system with compensation and proposes an optimal combination of energy components for compensating regular grid failure in industrial area with minimizing the pressure of electricity demand from national grid and minimizing the life cycle cost. The final optimization result from HOMER shows that the cost of energy (COE) for 0 hour, 1 hour, 2 hour, 3 hour, 4 hour, 5 hour, 6 hour, 7 hour, 8 hour and 9 hour compensation is respectively $0.092, $0.098, $0.106, $0.113, $0.123, $0.133, $0.144, $0.152, $0.159 and $0.163.
