Networked Control Systems （NCSs） employ digital network for transmitting control and monitoring information among system components. Control information over digital network may be delayed due to transmission and this can adversely affect the control performance. To achieve desired performance in the presence of delays the controller needs to modify its gains based on the channel delay. In this paper, we propose a simple adaptive regulator that uses the first order approximation for computing the controller gains based on prior knowledge of channel delays from experiments. Simulation results indicate that the adaptive regulator performs well even when we model the delay via Gaussian distribution. Delay samples obtained from MODBUS over TCP/IP and data-networks are used to illustrate the performance of the controller. The controller is implemented in True Time to illustrate its real-time performance.

How the morphology of captive-reared fish is affected by structural enrichment in their rearing tanks is not well *** studies have suggested that deficiencies in rearing environments could produce inappropriate body shape in salmonids(Vehanen and Huusko 2011).Garduho-Paz et al.(2010)have found significant differences in body and head shapes of 3-spine stickleback Gasterosteus aculeatus,depending on whether fish were reared in an environment with just gravel or in an environment enriched with large stones and artificial plants.

The aim of this investigation was to analyze the associations of TMJ pain/discomfort and bone characteristics on the activities of daily living in a population based study. Methods: The study included 95 randomly selected participants. The impact of temporomandibular joint pain/discomfort on the daily activeties was assessed by using the daily living scale by List and Helkimo (1995). The levels of serum type I collagen telopeptide fragments (P1NP), C-telopeptide crosslaps of type I collagen (CTX-1), and vitamin D (25 (OH) D) were analysed. The Mann-Whitney U-test, Spearman rank correlation coefficent (rs) were used for statistical analyses. Results: Activities of daily living were influenced by temporomandibular joint pain/discomfort to varying degrees. The degree of pain/discomfort during eating was correlated with the level of C-telopeptide crosslaps of type I collagen (p = 0.02) and type 1 collagen telopeptide fragments (p = 0.04). The females in the study had significantly lower vitamin D levels compared to males (p = 0.04). Conclusions: This population based study indicates that TMJ pain/discomfort exerts a significant negative influence on activities of daily living and is related to the biochemical markers of bone turnover and 25 (OH) D level. Several functions of daily activities such as social life, exercising and eating are the most disturbed.

Background: Separation-related disorders are prevalent in dogs and can result in problem behaviours such as inappropriate elimination, destructive behaviour, and distress vocalizations which occur when an owner is absent or perceived as absent. Numerous natural products are marketed for managing anxiety in dogs;however, few, if any, of these products have documented evidence of efficacy in veterinary behaviour. Purpose: This open, multicentric clinical trial aimed to assess the efficacy of a new supplement containing alpha-casozepine and fish muscle hydrolysate on the separation-related problem in dogs and the impact on the quality of life of dogs and their pet owners. Material and Methods: Fifty-one dogs with clinical signs compatible with separation-related problems were included. The dogs were treated with a complementary feed (Zylkene Plus, Vetoquinol, France) for 30 days. Separation-related behaviour assessment (SRP), emotional disorders assessment (EDED) and the quality of life (QoL) of the pets and their pet owner were assessed at baseline and the end of the study by the veterinarians. In addition, owners were asked to rate their dog’s SRP weekly after enrolment using the same questionnaire that the veterinarian used at the beginning of the study. Results: There was a statistically significant improvement in the SRP, EDED, and QoL scores (P Conclusion: The results of this study support the hypothesis that the combination of alpha-casozepine and fish muscle hydrolysate is a promising and effective option to reduce the frequency and severity of separation-related behaviour in dogs and improve the quality of dogs and their owners.
