In this research, an improved psychrometer is developed to solve practical issues arising in the relative humidity measurement of challenging drying environments for meat manufacturing in agricultural and agri-food industries. The design in this research focused on the structure of the improved psychrometer, signal conversion, and calculation methods. The experimental results showed the effect ...

This review deals with the recent findings on the microbial conversion of essential fatty acids (EFAs) through Pseudomonas aeruginosa PR3 NRRL-B-18602, and the antimicrobial properties of bioconverted EFAs, with particular emphasis on n-3 or n-6 fatty acids. The first section deals with the most recent and some background literature on which have been the latest developments with respect to bio...

This research investigates early mover advantage of a special group of online firms: entrepreneurial etailers that operate on third party eCommerce platforms. The conventional wisdom suggests that early mover advantage would not be substantial when barrier to entry is low. However, this research argues that etailers, even when barrier to entry is low online, can enjoy early mover advantage beca...

The automation products have been applied in various industries, especially in the water disposing industry. This paper describes the design of the hardware and the software of the monitoring system of sewage treatment which is based on S7-300 PLC (Programmable Logic Controller) and the Profibus bus technology. The hardware of PLC includes the power supply, CPU (Central Processing Unit), analog...

a detailed model of wind power station, including double fed induction generator, dfig is presented in this paper. two control mechanisms are included in the model. the inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. the outer control system is used for wind turbine pitch angle. pscad/emtdc is used ...

The localisation of graphical primitives is important task in image processing. This paper discusses problems of automatic computer-based detection and localisation of elementary shape in image. A genetic algorithm is used for this task. The using of genetic algorithm allows efficiently reduce time needed to scan a task state space. A modification of genetic algorithm for shape detection is pre...

AIM To investigate the disability due to musculoskeletal disorders of the upper extremities in heavy industry workers. METHODS The population under study consisted of 802 employees, both white- and blue-collar, working in a shipyard industry in Athens, Greece. Data were collected through the distribution of questionnaires and the recording of individual and job-related characteristics during ...

We study the structure of inter-industry relationships using networks of money flows between industries in 20 national economies. We find these networks vary around a typical structure characterized by a Weibull link weight distribution, exponential industry size distribution, and a common community structure. The community structure is hierarchical, with the top level of the hierarchy comprisi...
