This paper presents a discrete-time stable tracking control scheme for an underactuated vehicle modeled as a rigid body. This energy-based control scheme guarantees discrete-time stability of the feedback system. The underactuated vehicle is characterized by four control inputs for the six degrees of ...

Most power companies are wasting hot water in the sea, which is called the wasted warm water energy. This research attempts to develop the thermal energy management system of warm water energy that is utilized in a fish farming systems based on Internet of Things(IoT). It had developed a remote control ...
The main objective of this paper is to develop IOT based smart fish farm. In this project, we had designed the vertical fish farm and had done the analysis of fluid flow. The basic importance of this vertical aquarium is that it can be installed even in the narrow area countries where there is scarcity ...
In order to solve the food safety problems such as avian influenza and hormone chicken, food safety is also a part of public safety. Based on RFID and block chain technology, a foot ring based on block chain and RFID is designed. The use of block chain technology can not be tampered with, data sharing ...
Fish farming industry has become one of the sources of income to people who are involved in business. An entrepreneur in this industry can make more money when the fish pond is equipped with the suitable device. With the existence of such device which capable in controlling the water level, monitor ...
In this paper, a super twisting sliding mode controller based (ST-SMC) vector controlled speed sensorless permanent magnet synchronous motor (PMSM) driven single stage solar photovoltaic (PV) water pumping system is proposed. The ST-SMC minimizes chattering associated with the conventional SMC without ...
Water quality depends on various factors starting from climatic conditions to geographical location, chemical constitution to aquatic bio-diversity. Due to implicit relation between water quality to the quality of life environment and health, here, in this paper we propose an IoT inspired design in ...
Biological sampling for biomass estimation is a highly labor intensive process that can benefit from automation using computer vision. In this paper two algorithms the Green Layer Extraction (GLE) method and Morphology and Marker Controlled Watershed Transformation (MMCWT) method are proposed for the ...
Qualities of the light environment are important for good welfare in a number of species. In chickens, UVA light is visible and may facilitate flock interactions. UVB wavelengths promote endogenous vitamin D synthesis, which could support the rapid skeletal development of broiler chickens. The aim of ...
Effective implementation of management interventions is often limited by uncertainty, particularly in small-scale and developing-world fisheries. An effective intervention must have a measurable benefit, and evaluation of this benefit requires an understanding of the historical and socio-ecological ...
Background Egg size represents an important form of maternal effect determined by a complex interplay of long-term adaptation and short-term plasticity balancing egg size with brood size. Haplochromine cichlids are maternal mouthbrooders showing differential parental investment in different species, ...
Inadequately treated or untreated wastewater greatly contribute to the release of unwanted toxic contaminants into water bodies. Some of these contaminants are persistent and bioaccumulative, becoming a great concern as they are released into the environment. Despite the abundance of wastewater treatment ...
Background: The aim of this work was to evaluate phytotoxicity of the thiophene derivatives against three persistent weeds of a high degree of resistance (Galinsoga parviflora Cav., Rumex acetosa L., and Chenopodium album) as well as their ecotoxicological impact on Heterocypris incongruens. In addition, ...
Abstract Males of many fish species exhibit alternative reproductive tactics, which can influence the maturation schedules, fishery productivity, and resilience to harvest of exploited populations. While alternative mating phenotypes can persist in stable equilibria through frequency‐dependent selection, ...
Summary The supply of quality juveniles via land‐based larviculture represents a major bottleneck to the growing finfish aquaculture industry. As the microbiome plays a key role in animal health, this study aimed to assess the microbial community associated with early larval development of commercially ...
Ocean temperatures are rising; species are shifting poleward, and pH is falling (ocean acidification, OA). We summarise current understanding of OA in the brackish Baltic-Skagerrak System, focussing on the direct, indirect and interactive effects of OA with other anthropogenic drivers on marine biogeochemistry, ...
Neuroendocrine tumors (NETs) are rare neoplasms mostly originating from the gastroenteropancreatic tract (GEP-NETs). Data regarding nutritional status in GEP-NET patients are limited. The aim of the study was to investigate the nutritional status and adherence to the Mediterranean Diet (MD) in GEP-NET ...
