We review the current state of agricultural systems science, focusing in particular on the capabilities and limitations of agricultural systems models. We discuss the state of models relative to five different Use Cases spanning field, farm, landscape, regional, and global spatial scales and engaging ...
Agricultural system models have become important tools to provide predictive and assessment capability to a growing array of decision-makers in the private and public sectors. Despite ongoing research and model improvements, many of the agricultural models today are direct descendants of research investments ...
Large-scale cultivation of the European lobster (Homarus gammarus), a highly treasured seafood, has not been successful using prevalent communal rearing practices, much due to the fact that aggression towards conspecifics and cannibalism are naturally occurring behavioral traits in this species. We ...
The Indonesian government has made a clear policy to promote the use of the country’s maritime resources. One of the issues is to ensure Indonesian fish products can be marketed domestically and internationally in a competitive business environment. This paper highlights the global situation in fish ...
Three-River Headwaters Region is the complex ecosystem with typical characteristics of alpine grass land. Livestock husbandry is the main industry of yak husbandry. In recent years, with the continuous advance of industry 4.0, the data in the alpine animal husbandry has the problems of low standardization ...
In the many part of the word, availability of potable water is an issue as it is contaminated, there are basic qualitative observations that quickly determine if water is not safe to consume. To prevent the pollution, first part is to detect that pollutant. This system is to develop, implement, monitor ...
Mangrove forests constitute an important coastal ecosystem, which provides valuable ecosystem services such as coastal erosion protection, water filtration and shelters for a wide variety of plants and animals. Remote sensing satellite imagery provides valuable information for mangrove mapping and monitoring. ...
We develop a new object-based image analysis (OBIA) software system, named remote-sensing knowledge finder (RSFinder), based on the region-line primitive association framework (RLPAF). In this system, straight-edge lines are promoted as line primitives for OBIA, which is fundamentally different with ...
High SSC related to Dongjiakou Harbor construction was observed during June 2010 to August 2013. The adjacent Mytilus edulis aquaculture waters with area of 11.13 km2, 15.48 km2, and 24.27 km2 were affected by the high SSC retrieved from remote sensing SSC on 24 April 2011, 21 September 2011, and 10 ...
Derelict fishing gear produced by oyster farming activities is being dispersed along the southwestern coast of Taiwan. The derelict gear fragments littering at the coastal areas and is responsible for ghost fishing being a type of marine pollution. To address this problem, the paper presents an experimental ...
The Canadian Space Agency (CSA) in collaboration with the Naval Research Laboratory (NRL) and NASA are considering a coastal and inland water color hyperspectral imager as a complement to the NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission. This hyperspectral imager with 100 m spatial ...
Pollution in coastal areas is very hazardous for population. The problem is even higher when this pollution occurs in bathing areas such as beaches in populated areas. In this work we present a new automatic control application for wastewater plants when pollution is caused by those plants because there ...
This paper proposes a novel noncontact measuring approach for indoor objects with 3D laser camera on the principle of time-of-flight. By Capturing the actual indoor sphere, the initial point cloud image is obtained and firstly filtered with statistical outlier removal and voxel grid removal methods ...
In the favorable background of the Belt and Road Initiative, the aquatic products trade between China and ASEAN is facing a historic opportunity. In order to make guidance of transformation for the aquaculture enterprises, this article thoroughly make static and dynamic analyses on the situation of ...
Fossil fuels account for more than three-fourths of today's global energy consumption. The combustion of these fuels has contributed to the worsening of climate change and global warming. Fossil fuels are not only detrimental to the environment, but they are also not sustainable. In the Philippines, ...
This paper introduces an automated solar-powered aquaponics system, designed and implemented to be cost-effective and environmentally sound for local communities in Oman and other arid regions. It presents the design, construction and implementation of the following modules: 1) water recirculation system ...
This paper is using artificial neural network (ANN) to predict oxygen content in the water for the fish farm, so that decrease times of starts of oxygen suppliers. In Southern Taiwan, aquaculture is one of major economic industries. Especially, the important issue is how to effectively monitor the oxygen ...
The following topics are dealt with: systems theory; control theory; nonlinear control systems; finite time output feedback control; DC-DC buck power converters; distributed parameter systems; stochastic systems; system modeling; system identification; hybrid systems; optimal control; optimization; ...
Dissolved oxygen directly affects the growth status of fishes in intensive aquaculture, thus we set up a prediction model to determine the future changing trend of dissolved oxygen. The dissolved oxygen prediction model we proposed was based on the least squares support vector regression (LSSVR) model ...
This paper considers an optimal harvesting strategy problem arising in shrimp culture. The problem is formulated as an optimal control problem of nonlinear impulsive system. Since the impulsive switching constraints is very complex, the impulsive switching instants are unknown, and the objective function ...
