Deploying femtocells has been taken as an effective solution for removing coverage holes and improving wireless service performance in 3G-beyond wireless networks such as WiMAX and Long Term Evolution (LTE). This article investigates a novel framework of dynamic spectrum management for femtocell networks, called cognitive-empowered femtocells (CEF), aiming at mitigating both cross-tier and intratier interferences with minimum modifications required on the corresponding macrocell network. With the proposed framework, each CEF base station (BS) and the femtocell users can utilize spatiotemporally available radio resources for the access traffic. We conclude that the proposed CEF framework can effectively complement the existing femtocell design and serve as a value-added feature to the state-of-the-art femtocell technologies, while achieving high scalability and interoperability by minimizing the required modifications on the macrocell protocol design.

The development of pottery products was emphasized as the research and development project. The main ingredient was Nong Suea clay, Pathumthani province. Normally, Nong Suea clay was used for land-fill industries. However, the way to use Nong Suea clay as materials for pottery products could be a value added technology. In addition, the pottery products created from Nong Suea clay were used as the decorative materials. From the line blend method, six mixing ingredients were focused. The researcher found that the suitable mixing ingredient was the third formula that contained Nong Suea clay (80%) and Ranong white clay (20%). This formula was processed into five types of pottery products. Two temperatures were monitored for firing. First, the temperature at 850 °C was used for three different types of pots. This product was normally shaped by hand with a throwing wheel that led to the industrial process level. Second, the temperature at 1,200 °C was used for two different types of vases. The product decorations of these groups were applied by the flowing glaze technique which was suitable for long-term research and development. The craftmen in should be highly skilled, tool uses, and higher temperature capacity of kiln.

Logistics Process

Construction logistics process hides some non value added activities which are difficult to avoid, those activities have extended leading time which are not only cause the delay of the project completion, but also spend more production expenses that effect to the profit itself. Data rising by questionnaire is conducted in 22 qualified contractors around Denpasar with 3 respondents in each contractor. Data raising by questionnaire is done in 2 stages, first stage is questionnaire which identify wastes. Second stage are questionnaire which determine waste causes. Field observation is aimed to create a value steam mapping of construction logistic process. It had been found 7 types of wasting which often occurs. They are the field inspection, the purchase of one type material in different suppliers, awaiting the instruction of the owner, the delay of the material transportation, the purpose of approval or additional signature, clarification needs, awaiting the instruction of the superior. Afterwards, the cause of each wasting, namely the workers inspected are less skilled, the bad quality of goods given by the suppliers, the owner procedures which require workers await the instruction before working, material loading-unloading and distribution process is too slow, a complicated bureaucratic system and unclear information. And from the observation, it is obtained that there are some non-added activities occurred throughout the value stream of the construction project logistics, among them awaiting the approval of the supervisors, transportation, awaiting the order process which is still done manually and product defects during the material selection. As a wasting reduction, it is necessary to simplify the process, create a standard operation procedure, provide enough training to the workers so they are more independent, use an information technology to ease the delivery of the report, hold a long-term contracts with the suppliers and the internal customers.

Scheduling mechanism is the process of allocating radio resources to User Equipment (UE) that transmits different flows at the same time. It is performed by the scheduling algorithm implemented in the Long Term Evolution base station, Evolved Node B. Normally, most of the proposed algorithms are not focusing on handling the real-time and non-real-time traffics simultaneously. Thus, UE with bad channel quality may starve due to no resources allocated for quite a long time. To solve the problems, Exponential Blind Equal Throughput (EXP-BET) algorithm is proposed. User with the highest priority metrics is allocated the resources firstly which is calculated using the EXP-BET metric equation. This study investigates the implementation of the EXP-BET scheduling algorithm on the FPGA platform. The metric equation of the EXP-BET is modelled and simulated using System Generator. This design has utilized only 10% of available resources on FPGA. Fixed numbers are used for all the input to the scheduler. The system verification is performed by simulating the hardware co-simulation for the metric value of the EXP-BET metric algorithm. The output from the hardware co-simulation showed that the metric values of EXP-BET produce similar results to the Simulink environment.  Thus, the algorithm is ready for prototyping and Virtex-6 FPGA is chosen as the platform.

Novel Strategy

A novel strategy for the oxidation of Mg-based intermetallic compounds using CO<sub>2</sub> as an oxidizing agent was realized via simple thermal treatment, called ‘CO2-thermic Oxidation Process (CO-OP)’. Furthermore, as a value-added application, electrochemical properties of one of the reaction products (carbon-coated macroporous silicon) was evaluated. Considering the facile tunability of the chemical/physical properties of Mg-based intermetallics, we believe that this route can provide a simple and versatile platform for functional energy materials synthesis as well as CO<sub>2</sub> chemical utilization in an environment-friendly and sustainable way.
