. V. N. Ramesh,B. Naresh Kumar Reddy,V. V. Murali Krishna,B. M. Kumar Gandhi,V. Shiva,M. Dronika Devi 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.3
Now a days Jobs are Scheduled in a single processor or more than one processor, a real time job is scheduled or executed based on requirements, An Successful task in embedded system ought to have constrained asset necessities: Memory, execution time and power utilization, these necessity are not generally simple to fulfil in real-time embedded system with hard task deadlines. In this paper we explore the effective time utilization, without influencing the deadline requirements of typical hard real time task ,there are no limitation on the new results each task can be periodic or sporadic ,with relative deadline which can be less than ,equivalent to or greater than its period, it is too fast , best-effort ,effective real time scheduling algorithm for a wide variety of job parameters.
Diffusive and stochastic analysis of Lokta-Volterra model with bifurcation
C.V. Pavan Kumar,G. Ranjith Kumar,Kalyan Das,K. Shiva Reddy,Md. Haider Ali Biswas 한국전산응용수학회 2023 Journal of applied mathematics & informatics Vol.41 No.1
The paper presents a critical analysis of selected topics related to the modeling of interacting species in which prey has nonlinear reproduction, which is in competition with predator. The mathematical model's stochastic stability is investigated. The method of designing appropriate Lyapunov functions is used to identify permanence conditions among the parameters of the model and conditions for the structure to no longer be extinct. The system's two-dimensional diffusive stability is regarded and studied. The system experiences the process of saddle-node bifurcation by varying the death rate of predator parameter. Further effects of parameters that undergo inherent oscillations are numerically investigated, revealing that as the intensity of predation parameter b is increased, the device encounters non-periodic and damped oscillations.

Peptic ulcer owes its pathological features to disregulated oxido-nitrosative and necrotic changes in gastrointestinal mucosa. Xanthium strumarium L. is a ubiquitous, abundant herb possessing an array of pharmacological properties. In view of anti-inflammatory and antioxidant activity of Xanthium strumarium L., the present investigation was designed to unravel its antiulcer potential in pylorus ligation induced gastric ulcer in laboratory animals. X. srtumarium L. leaves were extracted by refluxing with 95 % ethanol to obtained X. srtumarium L. ethanolic extract (XSEE). After 1 h pretreatment period of XSEE (100, 200 and 400 mg/kg) gastric ulcer was induced by ligation of pylorus portion of stomach. Various parameters including volume of gastric fluid, pH of gastric fluid, free as well as total acidity were measured in the gastric fluid whereas ulcer area, ulcer index, mucin content, superoxide dismutase, myeloperoxidase, nitric oxide, total calcium, histamine level, membrane bound inorganic phosphate (Na-K-ATPase), TNF-${\alpha}$ level, DNA fragmentation were determined in the gastric tissue. Pretreatment with XSEE (200 and 400 mg/kg) significantly and dose dependently (P<0.01 and P<0.001) decreased ulcer area, ulcer index, macroscopical gastric damage score, volume of gastric fluid, free acidity as well as total acidity and mucin content. It also significantly increased pH of gastric fluid. Rats treated with XSEE (200 and 400 mg/kg) significantly and dose dependently (P<0.01 and P<0.001) attenuated decreased level of superoxide dismutase, nitric oxide and Na-K-ATPase. It also significantly decreased level of myeloperoxidase, calcium and inflammatory cytokine i.e. TNF-${\alpha}$. XSEE treated rats showed significant reduction in the pylorus ligation induced apoptotic changes. The possible mechanism by which Xanthium strumarium exerts its gastro-protective action may be due to free radical quenching, DNA repair and down regulation of oxidative-nitrosative stress along with cytokines.

Desiccant cooling mechanism is one of the alternate methods to control the humidity of air and temperature, compared to the conventional vapor compression method of air conditioning. Desiccant cooling doesn’t use harmful chemicals which effect the ozone layer and it saves lots of energy. Summer air condition system can use this technology since it removes the latent heat load from the room effectively and this process is economical. Selection of the appropriate liquid desiccant and packing material is very vital to obtain maximum dehumidification. This paper focuses on the different desiccants and packings used by different researchers to enhance the dehumidification. Simple and hybrid systems are also reviewed, and their comparison are presented based on the construction and dehumidification performance.
Time and Cost Analysis for Highway Road Construction Project Using Artificial Neural Networks
Naik, M. Gopal,Radhika, V. Shiva Bala Korea Institute of Construction Engineering and Ma 2015 Journal of construction engineering and project ma Vol.5 No.1
Success of the construction companies is based on the successful completion of projects within the agreed cost and time limits. Artificial neural networks (ANN) have recently attracted much attention because of their ability to solve the qualitative and quantitative problems faced in the construction industry. For the estimation of cost and duration different ANN models were developed. The database consists of data collected from completed projects. The same data is normalised and used as inputs and targets for developing ANN models. The models are trained, tested and validated using MATLAB R2013a Software. The results obtained are the ANN predicted outputs which are compared with the actual data, from which deviation is calculated. For this purpose, two successfully completed highway road projects are considered. The Nftool (Neural network fitting tool) and Nntool (Neural network/ Data Manager) approaches are used in this study. Using Nftool with trainlm as training function and Nntool with trainbr as the training function, both the Projects A and B have been carried out. Statistical analysis is carried out for the developed models. The application of neural networks when forming a preliminary estimate, would reduce the time and cost of data processing. It helps the contractor to take the decision much easier.

Heating ventilation air conditioning (HVAC) design mainly deals with moisture and its control. The moisture may be present inside ducts, conditioned spaces, or outdoors. The process of humidification and dehumidification requires equipment for mass and heat transfer, where the transfer of energy and mass takes place at varying concentrations and temperatures. The exchange of mass or heat depends on the type of flow and is conceivably in the form of gas to liquid or liquid–vapor. This paper aims to review the effect of moisture in the buildings and modulate its effect with several humidifying and dehumidifying techniques as sustainable techniques depending upon the external weather conditions to maintain thermal comfort. Various humidification and dehumidification techniques have been discussed with both their merits, limitations, applications and future scope to meet sustainable energy demands.
