Congestion in the merging roadways cannot be neglect, and it is necessary to build merging roadways in more massive scale by addressing it. In this paper, We compare the oblique shockwave in aerodynamic with the dynamic process in the merging roadways. Besides, We present the formation of the oblique shock wave in the turning section and merging section. Based on the similar mechanics between airflow and traffic flow, a traffic oblique shockwave model is proposed to explain the mechanics between the merging stream and the stream from the upstream. With this analogical model, we can obtain more regularities of the process of merging roadways.

As a private wireless network of smart grid, TD-LTE network use the same frequency band with other dedicated TD-LTE networks. There is an issue of co-channel interference to be studied. The co-channel interference could be described by Reference Signal Receiving Power (RSRP), Signal to Interference Plus Noise Ratio (SINR) at certain scrambling level and different interference field intensity. This paper presents a method to test the tolerance of the interference field intensity and the reference value of SINR in a certain RSRP value, with QoS as the evaluation index. The paper firstly investigates the category of smart grid services and Quality of Service (QoS) attribute value base on the specifications of power grid. Then the definition and causes of co-channel interference in LTE network are analyzed, and the method to evaluate the co-channel interference is given. Furthermore, a test by using the proposed method is given in the laboratory environment. More than 200 times of tests are repeated, and the delay, packet loss rate and throughput are obtained. The conclusion is finally given by comparing the test value with the required value of QoS. The data obtained in this test will provide reference for the design and optimization of the TD-LTE wireless network. And the method can be further used in the selection of the critical value of the finer network terminal RSRP.

During the development of a method using effective microorganisms (EM) to reduce the soil-to-plant transfer of 137Cs on land contaminated with radioactive Cs, an unexpected effect of EM on the reduction of the 137Cs activity in soil samples was observed. Laboratory experiments were then conducted to evaluate the impact of EM and fermented organic fertilizer (EM Bokashi) on the 137Cs activity in soil samples to investigate this observation. The experimental results indicate an increase in the 137Cs decay rate of up to 4 times the theoretical decay rate corresponding to the half-life of 137Cs, which is equal to 30.17 years. Our results suggest that EM accelerates the radioactive decay of 137Cs in soil.

The following article describes three case studies where Effective Microorganisms (EM) proved to be successful at recovering natural aquatic ecosystems as well as treating sewage and industrial waste water. The first case was at a water treatment plant that received the sewage water from two populated sectors of about 1’100,000 people within Guayaquil, the largest city in Ecuador. The efficacy of EM treatment was compared to an already established water treatment system using electrical aerators. In both cases, pH was maintained at a neutral range after 8 weeks and hydrogen sulfide, main cause of foul odors, was not detected after 5 weeks. The most significant difference was in the cost and used of energy. The second case consisted of treating the facilities of a slaughterhouse processing 1000 animals a day with the objective of reducing foul odors. EM was sprayed in all areas of the facility including floors, pathways, sewers and surrounding areas. Although no measurable parameters were evaluated, workers were interviewed to determine efficacy in reducing foul odors. After 5 months of treatment, employees and foremen agreed that foul odors were reduced almost completely to the point that employees did not feel the need to use masks. In addition, there was a consensus that the working conditions had significantly improved. The third case was the treatment of a natural estuary being contaminated with sewage water. Water samples and sediments were taken from the area receiving sewage water from the city sewage system. The following parameters were evaluated: Acidity, phosphates, organic matter, hydrogen sulfide, total suspended solids, populations of coliforms and salmonella. The results showed a significant decrease in phosphates, total suspended solids, organic matter and hydrogen sulfide, and a reduction in concentration of coliforms. Additionally, pH was maintained at neutral range allowing the proliferation of native life. These experiences demonstrate the versatility and efficacy of EM to mitigate water contamination due to human activities in populated cities.

Ecological data acquisition, refinement, and analysis methods have not kept pace with advancements in mobile sensor technology and applications of machine learning techniques due to the typical “stovepiping” of the sciences. Environmental sensor networks are an emerging technology which leverages advances in distributed sensing to realize real time rich data streams for researchers. When this network is made mobile it presents a disruptive technology with the potential to reveal new phenomena and questions as observations, that were once too dangerous or costly to obtain, becomes possible. In this concept paper, we motivate and present preliminaries in our investigation pertaining to the use of Autonomous Underwater Vehicles (AUVs) in swarms to realize a mobile sensor network targeting invasive species in the Great Lakes.

With the growth of the Internet and globalization, hardships in English speech communication became more serious for non-native speakers. It would be desirable to develop a speech communication device which can convert English speech into a more intelligible one for listeners. In this study, English speech was hypothesized to be more intelligible to non-native listeners by being modified into the listeners’ native language speaking style. First, the characteristics of English between native and Japanese speeches were statistically analyzed. The analysis determined the modification model marked modification of intonation of native speakers’ speech so as to include Japanese characteristics. The hypothesis was realized by speech modification generated by a speech analysis, modification and synthesis system, STRAIGHT. Then, the modified speeches were evaluated on the basis of listening experiments involving Japanese listeners. The experiments consisted of dictation tests and preference tests, and resulted in an increase in the scores. The results, therefore, verified the hypothesis. This also revealed the potential feasibility of the speech conversion method which facilitates spoken English communication.
