The rotary positive-displacement Roots mechanisms are popular used in industries and instruments as vacuum pump, blower, or supercharger, etc. As a mechanical blower design, its performances are affected by a variety of factors such as geometries, rotational speed, clearances, and operating processes. ...
In the process of intensive aquaculture production, it is essential and important to measure ammonia nitrogen concentration in water on-line. It affects the health of the aquaculture objects and it is the basis of closed-loop control and optimization. At present, it is measured by Ness's reagent method ...
Synthetic Aperture Radar (SAR) is an important composition on remote sensing. Computer intelligence is widely used in SAR data classification, this addresses the importance of studying the back scatter feature of the studied object. In this paper, Inverse Synthetic Aperture Radar (ISAR) images of floating ...
Presents the front cover or splash screen of the proceedings record.
The function of the reference electrode is to complete the pH measurement circuit, in conjunction with pH sensor. This paper described the characterization of in-house Reference Electrode (RE) using green colour electrolyte as a medium. The in-house RE was tested with few subjects such as commercial ...
Image processing and analysis techniques have drawn increasing attention since they enable a non-extractive and non-lethal approach to fisheries survey. To measure the fish size and length accurately, a reliable segmentation result is required. However, there are two major challenges about the segmentation. ...
This paper presents the development of a closed algal cultivation system that automatically monitors and controls significant bio-environmental parameters to optimize the growth of the microalgae Spirulina platensis, which is normally used as fish feeds. The system is composed of three major parts: ...
Presents the table of contents/splash page of the proceedings record.
This paper presents a simple method of tracking and counting fish images using an image processing technique. An experiment to capture images of fish population was conducted and fish images were processed using blob analysis and Euclidean filtering. The focus of this paper is to present the image processing ...
Portable systems are the trend nowadays, especially during this time that handheld devices have almost the same capability as with most of our computers. Developing a portable system for identifying the specie of a dried sea cucumber would be the focus of this study. Sea cucumber is one of the highest ...
Continuous water quality monitoring is important to the aquaculture industry but having this in real-time and accurate is expensive. Designing a multi-parameter portable water monitoring device will help fishermen maintain good water quality for the aquaculture. The system used a microcontroller to ...
Water quality is the first most important limiting factor in pond fish production. It is also one of the most difficult production factor to understand, predict and manage. It is not just where the fish live; its quality directly affects growth rates, the fish’s health and survival. Most fish kills, ...
Traditional farming and fishkeeping have enabled human populations to produce foods, but as communities grow though, less and less agricultural and farm land is available. In addition, due to climate change, producing crops progressively is a difficult thing to do. Aquaponics address these concerns. ...
Fighting poverty is one of the main objectives of sustainable development program. In a country like Lebanon, where poverty is a real threat and hidden under a good living looking, the situation should be explored in depth. This paper aims to evaluate the position of Lebanon compared to other Middle ...
In aquaculture, one of the most critical factors for sustaining life under the water is the dissolved oxygen (DO) since it affects not only the animal survival rate but also the growth rate. Therefore, in smart aquafarming, the DO content should be monitored thoroughly. As a consequence, in practice, ...
The dissolved oxygen (DO) measurement plays a crucial role in every automatic aerator-control system for shrimp farming because the DO affects both the animal survival rate and the growth rate. As a consequence, the accuracy degree of the DO sensor matters. The sensor with high accuracy is not economical. ...
The monitoring of water quality becomes a necessity in aquaculture system to ensure the growth and vitality of the fish. There exists several influencing factors to the water quality including acidity (pH), turbidity, dissolved oxygen and temperature level. As an alternative, the role of farmers could ...
Aquaponic NFT system is a merging system between hydroponic NFT and aquaculture. The NFT Aquaponic system needs circulation of water for 24 hours. Thus, It needs to monitor and control the level of ammonia, temperature, pH, and nutrients continuously for maintaining the environment of NFT Aquaponics. ...
The Macaronesia is a vast area playing a key role in the East boundary of the Central North-Atlantic Ocean-circulation system. Despite a significant research activity in ocean monitoring for decades using a wide range of observing systems and methodologies, the area is still under-sampled, mainly due ...
