 Abstract

This study confirmed that the aqueous extract of seaweed Ulva fasciata is capable of producing Silver nanoparticle (AgNPs) by reducing AgNO3 solution and is proved to be an efficient, eco-friendly and simple method. We have characterized the synthesized AgNPs using several techniques. The characteristic absorption peak at 249 nm in UV-Visible spectrum confirmed the formation of AgNPs. Crystalline nature of AgNPs is evident from the characteristic peaks in the XRD pattern. FESEM images revealed that the synthesized NPS are nearly spherical with size in the range 68.79-103.20 nm. The Characteristic peaks in the FTIR spectrum revealed the presence of Alcohols, Phenols, Alkanes and Amides, which is responsible for the formation of AgNPs. The outcome of this study is to know the methodology of green synthesis of silver nanoparticles and its characterization.

 Abstract

CT or MRI Medical imaging produces digital form of human body pictures. There exists a need for compression of these images for storage and communication purposes. Current compression schemes provide a very high compression rate with a considerable loss of quality. In medicine, it is necessary to have high image quality in region of interest, i.e. diagnostically important regions. This work discusses a model of lossless compression in region of interest with Block based PCA with high compression rate(CR) as well as high PSNR. Also the value of Mean Square Error (MSE) is very low. We evaluate our method on medical thyroid gland. This proposed method will reduce the errors caused due to manual analysis, time consuming, inaccurate and also eliminate the need of intensive trained person's in order to avoid diagnostic errors.

 Abstract

In this paper is the work based on the domination on Hamiltonian cycles in a graph. We discussed the nature and impact of domination on Hamiltonian graphs. The work is planned to study the Hamiltonian graphs and domination sets on any graph and type of dominations. We discussed the independent domination on a graph. Then using the properties of hamiltonicity of graphs and domination, we tried to find the domination sets in Hamiltonian graph.

 Abstract

The Internet of Things (IoT) has been broadly used to interconnect the accessible therapeutic assets and offer shrewd, dependable, and powerful social insurance administration to the elderly individuals. Wellbeing checking for dynamic and helped living is one of the standards that can utilize the IoT focal points to enhance the elderly way of life. In this paper, we display an IoT engineering tweaked for social insurance applications. The proposed engineering gathers the information and transfers it to the cloud where it is handled and broke down. Criticism activities in view of the investigated information can be sent back to the client. A model of the proposed engineering has been worked to show its execution points of interest.

 Abstract

In this paper, firstly an overview on MANET, their attacks, and encryption module are defined. In addition, a survey is carried out for MANET security. From, the survey found that AES is most used algorithm for data encryption as well as for key generation. The AES algorithm provides good security but not efficient in resource constraint devices. So, an Improved AES algorithm as an application for key generation for stream ciphers is proposed. In the Improved AES algorithm, by using Rijndaels substitution box and dynamic random shifting principle by reducing area and complexity as compared to AES, produced equivalent randomness. This paper introduces the concept of use of random initialization vector (IV) for resolving the replay attack on the network. The IV is randomly updated in each iteration and dependence of secret key on IV using nonlinear function producing the randomness of key. Moreover, based on NIST statistical analysis, it shows that more randomness is produced by proposed technique than A5/1 stream cipher.

 Abstract

: Lifestyle changes,urbanization and physical inactivity predispose an individual to the risk of Type 2 Diabetes Mellitus.Regular physical activity and regulated nutrition would prevent or delay the early onset of Diabetes.There is direct relationship between physical activity and metabolic health.Data indicate that 150 minutes per week of moderate to vigorous intensity physical activity brings significantly lower risks.Foods rich in soluble fiber can help lower blood cholesterol levels,enhance digestive health and minimize rise in blood sugar levels after a meal.

 Abstract

This study has been conducted to present a framework that showcases a performance excellence system using multiple regression model applied on weights derived from pair wise comparison matrices. The assessment criteria undertaken in this work are market esteem, leadership, business strategies and workforce. Companies or start ups can embrace the approach to strive for performance excellence and can expect to achieve performance goals by working on subtle fields. The assessment model can also irradiate the start up goals for aspiring ventures.
