Periodic intermittent cruise control: An innovative approach for reducing fuel consumption and exhaust emissions in road traffic systems

Motor vehicle exhaust emission has become an important source of global atmospheric emissions, and the urgency of protection and management of this issues has become increasingly prominent. The cooperative control strategy of road vehicles can comprehensively manage the individual vehicles from the whole perspective, which is a powerful means to achieve the goal of dual carbon goal. In the preliminary stage of the IoV, limited communication bandwidth increases the difficulty of designing the above cooperative cruise control scheme. To solve this problem, we designed a new novel periodic intermittent cruise controller to track and assess the real-time operating status and relevant environmental indicators of road vehicles. Compared with the previous continuous controller, the proposed controller subdivides the time domain into each sub-period, and the controller is activated merely during the working time interval of each period, which can effectively reduce the control cost. Besides, when the leading vehicle state changes, the following vehicle can quickly respond to the above adjustment and track the leading vehicles with the new desired speed and headway, thereby reduce the duration time and amplitude of road vehicle state oscillation. Based on the Lyapunov-like function method, the sufficient condition for the existence of designed periodically intermittent cruise controller is given, which guarantees that the closed-loop error dynamic system is satisfies exponential stable, and the controller gain coefficients in proposed control protocol can be obtained via solving a set of linear matrix inequalities with some commercial software built-in toolbox. At last, based on the VT-Microenvironment experiment evaluation model, we have carried out some numerical simulation experiments, and the results show that the periodic intermittent cruise control protocol is feasible in improving vehicle safety tracking performance, and remain valid in reducing energy consumption and exhaust emissions such as CO, HC, NOx, and approximately decreased by 2.52%, 6.65%, 34.75%, and 15.70% respectively from the rural value. This research result provides a technical reference to road traffic safety and environmental assessment.

The Equation on the Justice for Migrant workers: The Urgency of Protection on Prevention Smuggled Migrant worker based on Indonesian laws

Indonesia’s marine territory has become a big challenge for the Government of Indonesia to manage it. Nowadays, Indonesian marine has lot of regulation in the sea. But it’s cannot prevent the basic interest of all people that earnings life from there. A lot of migrant has been smuggled in and by Indonesian’s marine territory. The main concerns that arouse are: how should government give an equation for Indonesian migrant workers that are smuggled and how should the government put migrant workers protection to supply the equation for them. These questions will solve by a normative juridical study on the protection of natural resources and the resources of Indonesian fisherman. The study uses normative legal research which elaborated with conceptual approach from numbers of regulations that apply in marine labor law and employment law. This research is also complemented by a literature approach in the form of Indonesian legal literature and marine journals to address the issues raised in this paper. The findings in practice prove that the government should give more attention for the fisherman’s welfare and protection related to fish catching. The objective protection for Indonesian marine resources is from regulated all the regulation to develop Indonesia economic from Maritime sector. It is all needed to make a new system in legal protection for Fisherman and Marine Resources in Indonesia.

Groundwater contamination risk assessment using intrinsic vulnerability, pollution loading and groundwater value: a case study in Yinchuan plain, China.

Groundwater contamination risk assessment is a useful tool for groundwater pollution prevention and control. Previous study has evaluated groundwater contamination risk at Yinchuan Plain, China, according to aquifer vulnerability. The present study enriches the assessment of contamination risk by adding pollution loading, which represents the hazard from human activities, and groundwater value, which represents the economic loss as a result of groundwater pollution. An approach that combines toxicity, release possibility, and the potential release quantity of pollutants on the ground surface was used to estimate the pollution loading. An integrated approach that considered both the in situ and extractive values was used to estimate groundwater value. In addition, a basic risk map was constructed by overlying the vulnerability and pollution loading maps showing the potential probability of pollution, while a value-weighted risk map was produced by overlying the basic risk and value map indicating the urgency of protection. The validation by specific contaminants shows the reliability of the basic risk assessment. Both the basic and value-weighted risk maps indicate a very high groundwater contamination risk in Yinchuan City, and the southern part of Yinchuan Plain exhibited a relatively high contamination risk. As a result of not only high vulnerability but also very high pollution loading and groundwater value, Yinchuan City is the most urgent area requiring groundwater protection. The produced maps provide effective information for decision-making regarding the optimization of monitoring network, preferential treatment, and allocating future potentially hazardous.

Decomposition of a UWB Pulse in Structures with Facial Feedback

The urgency of protection of radio-electronic equipment from UWB pulses is indicated. The principle of modal filtration based on the application of the physical phenomenon of signal decomposition in transmission lines is shortly described. An asymmetric modal filter with facial feedback is analyzed. Its models with different parameters have been developed and manufactured. A field experiment and a computer simulation of the time response to a 1 ns pulse width have been performed. The agreement between the experimental and simulation results is demonstrated. For a modal filter with optimal parameters, the input pulse attenuation by 5 times is demonstrated in a 50-Ω channel.

PERLINDUNGAN HUKUM TERHADAP IKAN HIU DAN IKAN PARI UNTUK MENJAGA KESEIMBANGAN EKOSISTEM LAUT INDONESIA

The population of sharks and rays in Indonesia threatened with extinction. Based on the findings of WWF Indonesia that there are at least 10 million sharks caught in Indonesian waters each year for commercial purposes. Urgency of protection against sharks and stingrays are not only conservation activities related to efforts to save species of marine animals from extinction, but also related to global environmental issues. Until this time there has been no regulation of the Indonesian government, which specifically provides protection to the conservation of sharks and rays in Indonesia’s marine waters. In this paper, the author will discuss two findings. First, the lack of regulations that provide legal protection to sharks and stingrays from illegal fishing activity. Secondly, there are two efforts can be made by the government, repressive and preventive measures. A repressive measure carried out by law enforcement with a very heavy sanction the perpetrators of fishing of sharks and stingrays. Preventive efforts done by making shark conservation areas and through education and awareness to the community.

The Qingyuan Mushroom Culture System as Agricultural Heritage

Qingyuan County, Zhejiang, China is recognized as a source of mushrooms around the world and as Mushroom City in China. Because of a favorable ecological environment and abundant forest resources, mushroom farmers in Qingyuan have engaged in mushroom production for 800 years and continued to form unique mushroom production systems where people and nature live in a harmonious way, and a rich and colorful mushroom culture. The Qingyuan Mushroom Culture System was named the Nationally Important Agricultural Heritage systems of China in 2014. Based on analysis of the importance of agricultural heritage and the necessity and urgency of protection, here we examine the agricultural heritage of the Qingyuan mushroom culture system as a research case study and comprehensively describe its heritage values, including supply materials and production, ecosystem services, cultural inheritance and multi-function agricultural development. These results provide reference values for agricultural heritage protection and inheritance of edible fungi in China, agricultural sustainable development and extension of agricultural function.

Entomological Contributions to Human Welfare: Through Pest Control

Entomologists have a right to be proud of their profession and their accomplishments. Their efforts have contributed greatly to the human welfare of the United States and the benefits of their work are being felt throughout much of the world. At a time when the subject of agricultural chemicals is being critically reviewed it seems particularly appropriate for us to take a close look at some of these accomplishments and point out a few of the many cases where control has paid off. If such can be demonstrated, and I believe it can, we, as entomologists, must make a concerted attempt to once again bring about an understanding public to overcome the current skepticism towards insect control. To us this seems imperative, if we are to maintain an uninterrupted abundance of quality food, forage, and fiber. The contributions of the past may prove to be one of our most effective weapons in supporting our belief in the need and urgency of protection against insect pests. Let's look at the record.
