Abstract

Objective: The primary objective of this proposal is to explore the areas of applications for a Reconfigurable computing system and further to analyze the challenges in designing an Operating System suitable for such a computing environment. Method: In this paper we have discussed at length the issues in designing an operating system which will practically be suitable for a Reconfigurable computing environment. The different challenges faced by an Operatin System in handling the applications executed by a conventional CPU are analysed. The advantages of using the Field Programmable Gate Array (FPGA) in Reconfigurable Computing System (RCS) to handle complex applications and to increase the efficiency and throughput of the system are also discussed. Findings: A primary comparison was made with all existing strategies used in Reconfigurable Computing Systems. The inferences obtained from this analysis gave a clear picture that the objective can be achieved by designing a new OS or making some modifications in the kernel of the OS. By achieving this task, multitasking between the applications or processes can be done frequently yielding a far better performance and throughput. The challenges faced by an OS in dealing with the applications executed by the RCS can be eliminated to a greater extent. Improvements: By adopting these kind of designing strategies for the OS in a system with the programmable gate array, there is a considerable improvement and performance of the device also the life span of the device is increased which is considered as most important criteria for any users in computing environment. The new architecture and performance analysis is a research prone area in many of the leading Universities.

Abstract

Fluid handling equipment such as propellers, impellers, pumps posses the inherent risk of flow-dependent erosion-corrosion problems. Though there are many coating materials available to combat erosion-corrosion damage in the above components, iron based amorphous coatings exhibits high erosion-corrosion resistance. High velocity oxy-fuel (HVOF) spray process is extensively used to deposit erosion-corrosion resistance amorphous coatings. In this investigation, iron based amorphous metallic coating was deposited on 316 stainless steel using HVOF spray process by varying the parameters such as oxygen flow rate, fuel flow rate, powder feed rate, carrier gas flow rate, and spray distance. Empirical relationships were established to predict the porosity and micro hardness of iron based amorphous coating. Microstructure observations of the coating were done by optical microscope. From the results, it is found that, fuel flow rate and spray distance appeared to be the most significant parameters affecting the mechanical properties of the iron based amorphous coating.

Abstract

The primary objective of this proposal is to minimize the battery drain and to maximize the compatibility of the device so that the complexity of the device is much more reduced to enhance the battery period considerably. In this paper we adopted a method for increasing the response time using a priority based algorithm along with Field Programmable Gate Array (FPGA) in Reconfigurable Computing System (RCS) to handle complex applications and to increase the efficiency and throughput of the system. A primary comparison was made with all existing algorithms namely First Come First Serve (FCFS), Round Robin, Shortest Job First (SJF) for a given set of processes by taking process delay as a core parameter. The result obtained from this analysis gave a clear picture that the objective can be achieved by decreasing the waiting time and by increasing the throughput. By achieving this task, multitasking between the applications or processes can be done frequently. By adopting these kind of scheduling algorithms with programmable gate array, there is a considerable improvement and performance of the device. Also, the life span of the device is increased which is considered as most important criteria for any users in computing environment.

Abstract

This investigation was carried out in Tamil Nadu Agricultural University, Coimbatore to test the bio efficacy of different seed dressing chemical on the management of sorghum shoot fly. The micro plot field experiments conducted in farm holdings at Chinnamatham palayam and Idikarai, Coimbatore District revealed the effectiveness of imidacloprid in checking shoot fly incidence by recording a mean minimum dead heart damage of 20 and 11 per cent in trial I and II, respectively. The experiments also showed maximum plant height of 39.2 and 39.7 cm in imidacloprid treated plots. In the laboratory, the assessment of seed dressing chemicals on the germination indicated maximum germination (92 %) of sweet sorghum seeds in imidacloprid treatment with maximum seedling vigour index (2401.2). Laboratory experiments showed no adverse effect of imidacloprid and thiamethoxam on seed germination.

Abstract

Objective: The aim of this study was to Evaluation of altered temporomandibular disc position in symptomatic TMD patients with pre and post gnathological splint therapy.

Materials and Method: This study included ten patients with a mean age of 21.5 years with maxillary transverse deficiency treated with the skeletal expander. The study consisted of 15 patients with a mean age of 25 years with clinically symptomatic and orthodontically untreated TMD patients with splint therapy. Statistical analysis was performed using paired t‑test.

Results: The mean AS, SS, and PS values for right TMJ that was 0.2mm (SD ±0.6mm), 0.5mm(SD± 0.3mm), 0.4mm(SD±0.1mm), respectively and the mean difference between AS, SS, and PS values for left TMJ was 0.2mm (SD±0.1mm), 0.5mm (SD± 0.05mm), and 0.2mm (SD± 0.2mm). The ratio of AS to SS to PS was 0.2to 0.5to 0.4, No significant sex difference was noted in joint space distances. The results showed less variability of condylar position in the fossa than in normal subjects.

Conclusion: Gnathological splints can be used as effectiveness mean for treatment of such patients. This can be easy made good comfort to the patients.

Abstract

With the rapid advancement of Information and Communication Technology (ICT), the way of doing business and lifestyle has been changed over the past three decades. The best way to consider about ICT is to regard all the benefits of the digital technology that is present which is used to assist organizations or businesses and individuals. It includes any product that stores, controls, retrieves, receives or transmits information digitally. Thus, ICT has become a basic building block of the contemporary society. The aim of this paper is to identify the current status, uses of ICT as well as the challenges it is facing.
